+                            Announcing ncurses 6.4
+
+Overview
+
+   The  ncurses  (new  curses)  library  is  a free software emulation of
+   curses  in  System  V  Release  4.0 (SVr4), and more. It uses terminfo
+   format,  supports  pads  and  color  and multiple highlights and forms
+   characters and function-key mapping, and has all the other SVr4-curses
+   enhancements  over  BSD curses. SVr4 curses became the basis of X/Open
+   Curses.
+
+   In  mid-June  1995,  the  maintainer of 4.4BSD curses declared that he
+   considered  4.4BSD curses obsolete, and encouraged the keepers of unix
+   releases such as BSD/OS, FreeBSD and NetBSD to switch over to ncurses.
+
+   Since 1995, ncurses has been ported to many systems:
+     * It is used in almost every system based on the Linux kernel (aside
+       from some embedded applications).
+     * It  is  used  as the system curses library on OpenBSD, FreeBSD and
+       MacOS.
+     * It  is used in environments such as Cygwin and MinGW. The first of
+       these was EMX on OS/2 Warp.
+     * It is used (though usually not as the system curses) on all of the
+       vendor  unix  systems,  e.g.,  AIX,  HP-UX,  IRIX64, SCO, Solaris,
+       Tru64.
+     * It should work readily on any ANSI/POSIX-conforming unix.
+
+   The distribution includes the library and support utilities, including
+     * captoinfo, a termcap conversion tool
+     * clear, utility for clearing the screen
+     * infocmp, the terminfo decompiler
+     * tabs, set tabs on a terminal
+     * tic, the terminfo compiler
+     * toe, list (table of) terminfo entries
+     * tput,  utility  for  retrieving  terminal  capabilities  in  shell
+       scripts
+     * tset, to initialize the terminal
+
+   Full manual pages are provided for the library and tools.
+
+   The ncurses distribution is available at ncurses' homepage:
+
+     https://invisible-island.net/archives/ncurses/ or
+     https://invisible-mirror.net/archives/ncurses/ .
+
+   It is also available at the GNU distribution site
+
+     https://ftp.gnu.org/gnu/ncurses/ .
+
+Release Notes
+
+   These notes are for ncurses 6.4, released December 31, 2022.
+
+   This  release  is  designed  to  be source-compatible with ncurses 5.0
+   through  6.3; providing extensions to the application binary interface
+   (ABI).  Although  the  source  can  still be configured to support the
+   ncurses  5  ABI, the reason for the release is to reflect improvements
+   to the ncurses 6 ABI and the supporting utility programs.
+
+   There  are,  of  course,  numerous  other improvements, listed in this
+   announcement.
+
+   The   most  important  bug-fixes/improvements  dealt  with  robustness
+   issues.  The  release notes also mention some other bug-fixes, but are
+   focused  on  new  features and improvements to existing features since
+   ncurses 6.3 release.
+
+  Library improvements
+
+    New features
+
+   There are no new features in this release.
+
+    Other improvements
+
+   These are improvements to existing features:
+     * modify  delscreen  to  more  effectively delete all windows on the
+       given screen.
+     * modify  wnoutrefresh  to  call  pnoutrefresh if its parameter is a
+       pad,  rather than treating it as an error, and modify new_panel to
+       permit its window-parameter to be a pad
+     * modify  curses_trace()  to  show  the trace-mask as symbols, e.g.,
+       TRACE_ORDINARY, DEBUG_LEVEL(3).
+     * improve  checks  for valid mouse events when an intermediate mouse
+       state is not part of the mousemask specified by the caller
+     * allow extended-color number in opts parameter of wattr_on.
+     * improve _tracecchar_t2 formatting of base+combining character.
+     * trim  out some unwanted linker options from ncurses*config and .pc
+       files seen in Fedora 36+.
+     * improve shell-scripts with shellcheck
+     * improve use of "trap" in shell scripts, using a script.
+     * modify make-tar.sh scripts to make timestamps more predictable.
+
+   These are corrections to existing features:
+     * modify  misc/gen-pkgconfig.in  to  allow  for  the  case where the
+       library  directory  does  not  yet  exist, since this is processed
+       before doing an install
+     * set trailing null on string passed from winsnstr to wins_nwstr.
+     * modify  waddch_literal  to  allow  for double-width base character
+       when merging a combining character
+
+  Program improvements
+
+   Several improvements were made to the utility programs:
+
+   infocmp
+
+          + rewrite  canonical_name  function of infocmp to ensure buffer
+            size
+          + improve  readability  of  long parameterized expressions with
+            the  infocmp  "-f"  option  by  allowing  split before a "%p"
+            marker.
+          + modify   verbose-option   of  infocmp,  tic,  toe  to  enable
+            debug-tracing if that is configured.
+
+   tabs
+          limit tab-stop values to max-columns
+
+   tic
+          add   consistency   check   in   tic  for  u6/u7/u8/u9  and  NQ
+          capabilities.
+
+   tput
+          corrected use of original tty-modes in init/reset subcommands
+
+    Examples
+
+   Along  with  the  library and utilities, improvements were made to the
+   ncurses-examples.  Most  of  this  activity  aimed  at  improving  the
+   test-packages:
+     * add  minimal  -h  (usage)  and  -V  (version)  getopt logic to all
+       ncurses-examples programs.
+     * fix an error in "@" command in test/ncurses.c F-menu
+     * add curses_trace to ifdef's for START_TRACE in test/test.priv.h
+     * improve pthread-configuration for test/worm.c
+     * add setlocale call to several test-programs.
+     * workaround  in  test/picsmap.c  for  use of floating point for rgb
+       values by ImageMagick 6.9.11, which appears to use the wrong upper
+       limit.
+     * use  static libraries for AdaCurses test-package for Mageia, since
+       no gprbuild package is available.
+     * install  Ada95  sample  programs  in  libexecdir, adding a wrapper
+       script to invoke those.
+     * install  ncurses-examples programs in libexecdir, adding a wrapper
+       script to invoke those.
+
+   There are other new demo/test programs and reusable examples:
+
+   test/combine
+          demonstrate combining characters
+
+   test/test_delwin
+          demonstrate deleting a window
+
+   test/test_mouse
+          observe  mouse  events  in  the  raw terminal or parsed ncurses
+          modes
+
+   test/test_unget_wch
+          demonstrate the unget_wch and unget functions
+
+  Terminal database
+
+   There are several new terminal descriptions:
+     * mosh
+     * mosh-256color
+     * teken-16color
+     * teken-sc
+     * teken-vt
+     * xgterm
+
+   There  are  many  changes to existing terminal descriptions. Some were
+   updates to several descriptions:
+     * make description-fields distinct
+     * fix errata in description fields
+     * add/use several building-blocks:
+          + aixterm+sl
+          + ansi+cpr
+          + apollo+vt132
+          + decid+cpr
+          + ncr260vp+sl
+          + wyse+sl
+          + x10term+sl
+          + xterm+acs
+          + xterm+alt47
+
+   while  others  affected specific descriptions. These were retested, to
+   take into account changes by their developers:
+     * kitty
+     * teken
+
+   while  these are specific fixes based on reviewing documentation, user
+   reports, or warnings from tic:
+
+   att610+cvis0
+          amended note as per documentation for att610, att620, att730
+
+   kon, kon2, jfbterm
+          revise to undo "linux2.6" change to smacs/rmacs/enacs
+
+   st-0.6
+          add dim, ecma+strikeout
+
+   foot+base
+          add xterm+sl-alt
+
+   dec+sl
+          correct dsl in dec+sl
+
+   mintty and tmux
+          correct setal in mintty/tmux entries, add to vte-2018
+
+   nsterm
+          modify nsterm to use xterm+alt1049
+
+   putty
+          modify putty to use xterm+alt1049
+
+   vte-2018
+          add blink and setal
+
+   A few entries use extensions (user-defined terminal capabilities):
+     * use  ansi+enq  and  decid+cpr in cases where the terminal probably
+       supported the u6-u9 extension
+     * remove u6-u9 from teken-2018
+     * use  NQ  to flag entries where the terminal does not support query
+       and response
+     * add/use bracketed+paste to help identify terminals supporting this
+       xterm feature
+     * modify  samples  for xterm mouse 1002/1003 modes to use 1006 mode,
+       and also provide for focus in/out responses
+     * xterm  patch  #371 supports DEC-compatible status-line. add dec+sl
+       to  xterm-new, per xterm #371, add xterm-p371, add xterm-p370, for
+       use  in  older  terminals, and set "xterm-new" to "xterm-p370" (to
+       ease adoption).
+
+  Documentation
+
+   As usual, this release
+     * improves documentation by describing new features,
+     * attempts  to  improve the description of features which users have
+       found confusing
+     * fills  in overlooked descriptions of features which were described
+       in the NEWS file but treated sketchily in manual pages.
+
+   In  addition  to  providing  background  information  to explain these
+   features   and   show   how   they  evolved,  there  are  corrections,
+   clarifications, etc.:
+     * Corrections:
+          + remove a stray '/' from description of %g in terminfo(5).
+          + correct/improve  font-formatting in curs_getch.3x, as well as
+            other manual pages.
+     * New/improved history and portability sections:
+          + add portability notes for delscreen and delwin in manual.
+          + improve curs_slk.3x discussion of extensions and portability
+     * Other improvements:
+          + improve  curs_bkgd.3x,  explaining  that  bkgdset  can affect
+            results for bkgd
+          + add note on portable memory-leak checking in curs_memleaks.3x
+          + expanded description in resizeterm.3x
+          + add  section  on  releasing  memory  to  curs_termcap.3x  and
+            curs_terminfo.3x manpages.
+          + add  clarification  of  the  scope  of  dynamic  variables in
+            terminfo(5).
+          + improve formatting of ncurses-intro.html and hackguide.html
+          + improve curs_clear.3x links to other pages
+          + update  ncurses-howto,  making documentation fixes along with
+            corrections to example programs.
+          + use  newer  version  1.36 of gnathtml for generating Ada html
+            files.
+          + update external links in Ada95.html
+
+   There  are  no new manual pages (all of the manual page updates are to
+   existing pages).
+
+  Interesting bug-fixes
+
+   While  there  were  many bugs fixed during development of ncurses 6.4,
+   only  a  few  (the  reason  for  this release) were both important and
+   interesting. Most of the bug-fixes were for local issues which did not
+   affect  compatibility across releases. Since those are detailed in the
+   NEWS file no elaboration is needed here.
+
+   The  interesting  bugs were those dealing with memory leaks and buffer
+   overflows.  Although  the utilities are designed for text files (which
+   they do properly), some choose to test them with non-text files.
+     * Text  files  contain  no  embedded  nulls.  Also,  they end with a
+       newline.  Feeding tic non-text files exposed a few cases where the
+       program  did  not  check  for  those  issues. As a result, further
+       processing  of the input found limit-checks whose assumptions were
+       invalid.
+     * Fixing  the limit-checks (first) found a problem with tic managing
+       the  list  of  strings  in  a terminal description. In merging two
+       terminal  descriptions  (i.e.,  the  "use="  feature), tic was not
+       allocating  a  complete copy. A quick repair for that introduced a
+       memory leak.
+     * The  checks  for non-text files are improved (i.e., embedded nulls
+       in  the  input  file  will  cause  tic  to  reject  it rather than
+       attempting to process it).
+     * The string allocations in tic are likewise improved.
+
+  Configuration changes
+
+    Major changes
+
+   There  are  no  major  changes.  No  new  options  were added. Several
+   improvements were made to configure checks.
+
+    Configuration options
+
+   There are a few new/modified configure options:
+
+   --with-abi-version
+          add ABI 7 defaults to configure script.
+
+   --with-caps
+          add   warning   in  configure  script  if  file  specified  for
+          "--with-caps" does not exist.
+
+   --with-manpage-format
+          bzip2 and xz compression are now supported
+
+   --with-xterm-kbs
+          add    check/warning    in    configure    script   if   option
+          "--with-xterm-kbs" is missing or inconsistent
+
+  Portability
+
+   Many  of  the  portability  changes  are implemented via the configure
+   script:
+     * amend  configure option's auto-search to account for systems where
+       none of the directories known to pkg-config exist
+     * corrected regex needed for older pkg-config used in Solaris 10
+     * improve  handling of --with-pkg-config-libdir option, allowing for
+       the case where either $PKG_CONFIG_LIBDIR or the option value has a
+       colon-separated list of directories
+     * if   the   --with-pkg-config-libdir   option  is  not  given,  use
+       ${libdir}/pkgconfig as a default
+     * improve search-path check for pkg-config, e.g., for Debian testing
+       which installs pkg-config with architecture-prefixes.
+     * build-fix for cross-compiling to MingW, conditionally add -lssp
+     * improve configure check for getttynam
+     * fixes to build with dietlibc:
+          + add configure check for fpathconf
+          + add   configure   check   for  math  sine/cosine,  needed  in
+            test/tclock, and eliminate pow() from test/hanoi
+          + use wcsnlen as an alternative to wmemchr if it is not found
+     * modify  configure macro CF_BUILD_CC to check if the build-compiler
+       works,  rather  than that it is different from the cross-compiler,
+       e.g.,  to  accommodate  a  compiler  which  can be used for either
+       purpose with different flags
+     * modify  configure/scripts  to work around interference by GNU grep
+       3.8
+
+   Here are some of the other portability fixes:
+     * change  man_db.renames  to  template,  to  handle  ncurses*-config
+       script with the --extra-suffix configure option.
+     * update   CF_XOPEN_SOURCE  macro,  adding  variants  "gnueabi"  and
+       "gnueabihf" to get _DEFAULT_SOURCE special case, as well as adding
+       GNU  libc  suffixes for "abi64", "abin32", "x32" to distinguish it
+       from other libc flavors.
+     * work  around  musl's  nonstandard  use  of  feature test macros by
+       adding  a  definition  for NCURSES_WIDECHAR to the generated ".pc"
+       and *-config files.
+     * use  "command  -v"  rather than "type" in Ada95/gen/Makefile.in to
+       fix a portability issue.
+     _________________________________________________________________
+
+Features of ncurses
+
+   The  ncurses  package  is  fully upward-compatible with SVr4 (System V
+   Release 4) curses:
+     * All of the SVr4 calls have been implemented (and are documented).
+     * ncurses  supports  all  of  the for SVr4 curses features including
+       keyboard  mapping,  color,  forms-drawing with ACS characters, and
+       automatic recognition of keypad and function keys.
+     * ncurses  provides  these SVr4 add-on libraries (not part of X/Open
+       Curses):
+          + the  panels  library,  supporting  a  stack  of  windows with
+            backing store.
+          + the   menus   library,  supporting  a  uniform  but  flexible
+            interface for menu programming.
+          + the   form   library,   supporting  data  collection  through
+            on-screen forms.
+     * ncurses's  terminal database is fully compatible with that used by
+       SVr4 curses.
+          + ncurses  supports user-defined capabilities which it can see,
+            but  which are hidden from SVr4 curses applications using the
+            same terminal database.
+          + It  can  be optionally configured to match the format used in
+            related systems such as AIX and Tru64.
+          + Alternatively,  ncurses  can  be  configured  to  use  hashed
+            databases  rather  than  the  directory of files used by SVr4
+            curses.
+     * The ncurses utilities have options to allow you to filter terminfo
+       entries for use with less capable curses/terminfo versions such as
+       the HP-UX and AIX ports.
+
+   The ncurses package also has many useful extensions over SVr4:
+     * The  API  is 8-bit clean and base-level conformant with the X/OPEN
+       curses  specification, XSI curses (that is, it implements all BASE
+       level  features,  and  most  EXTENDED  features). It includes many
+       function calls not supported under SVr4 curses (but portability of
+       all calls is documented so you can use the SVr4 subset only).
+     * Unlike  SVr3 curses, ncurses can write to the rightmost-bottommost
+       corner  of  the  screen  if  your terminal has an insert-character
+       capability.
+     * Ada95 and C++ bindings.
+     * Support  for mouse event reporting with X Window xterm and FreeBSD
+       and OS/2 console windows.
+     * Extended mouse support via Alessandro Rubini's gpm package.
+     * The  function  wresize  allows  you  to resize windows, preserving
+       their data.
+     * The  function  use_default_colors allows you to use the terminal's
+       default colors for the default color pair, achieving the effect of
+       transparent colors.
+     * The functions keyok and define_key allow you to better control the
+       use of function keys, e.g., disabling the ncurses KEY_MOUSE, or by
+       defining  more  than  one  control  sequence to map to a given key
+       code.
+     * Support for direct-color terminals, such as modern xterm.
+     * Support for 256-color terminals, such as modern xterm.
+     * Support for 16-color terminals, such as aixterm and modern xterm.
+     * Better  cursor-movement  optimization.  The package now features a
+       cursor-local-movement computation more efficient than either BSD's
+       or System V's.
+     * Super   hardware   scrolling   support.   The  screen-update  code
+       incorporates  a novel, simple, and cheap algorithm that enables it
+       to  make  optimal  use  of hardware scrolling, line-insertion, and
+       line-deletion  for  screen-line  movements. This algorithm is more
+       powerful than the 4.4BSD curses quickch routine.
+     * Real  support  for  terminals  with  the  magic-cookie glitch. The
+       screen-update  code  will  refrain from drawing a highlight if the
+       magic-   cookie  unattributed  spaces  required  just  before  the
+       beginning  and  after the end would step on a non-space character.
+       It  will  automatically  shift  highlight boundaries when doing so
+       would  make it possible to draw the highlight without changing the
+       visual appearance of the screen.
+     * It  is  possible to generate the library with a list of pre-loaded
+       fallback  entries linked to it so that it can serve those terminal
+       types  even  when  no  terminfo tree or termcap file is accessible
+       (this  may  be useful for support of screen-oriented programs that
+       must run in single-user mode).
+     * The tic/captoinfo utility provided with ncurses has the ability to
+       translate  many  termcaps  from  the XENIX, IBM and AT&T extension
+       sets.
+     * A BSD-like tset utility is provided.
+     * The ncurses library and utilities will automatically read terminfo
+       entries  from  $HOME/.terminfo  if  it exists, and compile to that
+       directory  if  it  exists  and the user has no write access to the
+       system  directory.  This feature makes it easier for users to have
+       personal  terminfo  entries without giving up access to the system
+       terminfo directory.
+     * You  may  specify  a  path  of  directories to search for compiled
+       descriptions  with  the  environment  variable TERMINFO_DIRS (this
+       generalizes  the  feature  provided by TERMINFO under stock System
+       V.)
+     * In  terminfo  source files, use capabilities may refer not just to
+       other entries in the same source file (as in System V) but also to
+       compiled  entries  in  either the system terminfo directory or the
+       user's $HOME/.terminfo directory.
+     * The  table-of-entries  utility  toe makes it easy for users to see
+       exactly what terminal types are available on the system.
+     * The library meets the XSI requirement that every macro entry point
+       has  a  corresponding  function  which  may be linked (and will be

+
+Applications using ncurses
+
+   The  ncurses  distribution  includes  a  selection  of  test  programs
+   (including   a   few   games).   These  are  available  separately  as
+   ncurses-examples
+
+   The   ncurses   library  has  been  tested  with  a  wide  variety  of
+   applications including:
+
+   aptitude
+          FrontEnd to Apt, the debian package manager
+
+          https://wiki.debian.org/Aptitude
+
+   cdk
+          Curses Development Kit
+
+          https://invisible-island.net/cdk/

+   dialog
+          the  underlying  application used in Slackware's setup, and the
+          basis   for  similar  install/configure  applications  on  many
+          systems.
+
+          https://invisible-island.net/dialog/

+          file-transfer utility
+
+          https://www.ncftp.com/
+

+
+   vifm
+          File manager with vi like keybindings
+
+          https://vifm.info/
+
+   as well as some that use ncurses for the terminfo support alone:
+
+   minicom
+          terminal emulator for serial modem connections
+
+          https://alioth.debian.org/projects/minicom/
+
+   mosh

+
+          https://invisible-island.net/ncurses/tack.html
+
+   tmux
+          terminal multiplexor
+
+          https://github.com/tmux/tmux/wiki
+
+   vile
+          vi-like-emacs  may  be  built  to  use the terminfo, termcap or
+          curses interfaces.
+
+          https://invisible-island.net/vile/
+
+   and finally, those which use only the termcap interface:
+
+   emacs
+          text editor
+
+          https://www.gnu.org/software/emacs/
+
+   less
+          The  most  commonly  used  pager  (a program that displays text
+          files).

+   screen
+          terminal multiplexor
+
+          https://www.gnu.org/software/screen/
+
+   vim
+          text editor
+
+          https://www.vim.org/
+
+Development activities
+
+   Zeyd  Ben-Halim  started  ncurses  from  a  previous  package pcurses,
+   written  by  Pavel  Curtis.  Eric  S.  Raymond  continued development.
+   Juergen Pfeifer wrote most of the form and menu libraries.
+
+   Ongoing development work is done by Thomas E. Dickey. Thomas E. Dickey
+   has  acted  as  the maintainer for the Free Software Foundation, which
+   held  a  copyright  on ncurses for releases 4.2 through 6.1. Following
+   the release of ncurses 6.1, effective as of release 6.2, copyright for
+   ncurses  reverted  to  Thomas  E.  Dickey  (see  the  ncurses  FAQ for
+   additional information).
+
+   Contact the current maintainers at
+
+     bug-ncurses@gnu.org
+
+   To join the ncurses mailing list, please write email to
+
+     bug-ncurses-request@gnu.org
+
+   containing the line:
+
+     subscribe <name>@<host.domain>
+
+   This list is open to anyone interested in helping with the development
+   and testing of this package.
+
+   Beta versions of ncurses are made available at
+
+     https://invisible-island.net/archives/ncurses/current/ and
+     https://invisible-mirror.net/archives/ncurses/current/ .
+
+   Patches to the current release are made available at
+
+     https://invisible-island.net/archives/ncurses/6.3/ and
+     https://invisible-mirror.net/archives/ncurses/6.3/ .
+
+   There is an archive of the mailing list here:
+
+     http://lists.gnu.org/archive/html/bug-ncurses (also https)
+
+Related resources
+
+   The  release notes make scattered references to these pages, which may
+   be interesting by themselves:
+     * ncurses licensing
+     * Symbol versioning in ncurses
+     * Comments on ncurses versus slang (S-Lang)
+     * Comments on OpenBSD
+     * tack - terminfo action checker
+     * tctest - termcap library checker
+     * Terminal Database
+
+Other resources
+
+   The  distribution  provides  a  newer  version  of the terminfo-format
+   terminal description file once maintained by Eric Raymond . Unlike the
+   older  version, the termcap and terminfo data are provided in the same
+   file, which also provides several user-definable extensions beyond the
+   X/Open specification.
+
+   You  can  find  lots  of  information  on  terminal-related topics not
+   covered  in  the  terminfo  file  at  Richard  Shuford's archive . The
+   collection of computer manuals at bitsavers.org has also been useful.

+dnl and is scheduled for release in P1003.1 Issue 8 (late 2022).

+dnl
+dnl + This is a GNU make feature (since April 1988, but in turn from binutils,

+dnl
+dnl + It was adopted in NetBSD make in June 1995.
+dnl
+dnl + The other BSD make programs are derived from the NetBSD make (and for
+dnl   that reason are not actually different "implementations").
+dnl
+dnl + Some features of NetBSD make were actually adapted from pmake, which
+dnl   began as a modified GNU make starting in 1993.
+dnl
+dnl + Version 3.8 of the dmake program in January 1992 also implemented this

+dnl version) of ncurses don't define either __NCURSES_H or NCURSES_VERSION in
+dnl the header.
+dnl
+dnl If the installer has set $CFLAGS or $CPPFLAGS so that the ncurses header
+dnl is already in the include-path, don't even bother with this, since we cannot

+dnl library.
+dnl
+dnl Notes:
+dnl a) ${LOCAL_LDFLAGS} is used to link executables that will run within
+dnl the build-tree, i.e., by making use of the libraries that are compiled in
+dnl $rel_builddir/lib We avoid compiling-in a $rel_builddir/lib path for the
+dnl shared library since that can lead to unexpected results at runtime.
+dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
+dnl libraries are compiled in ../../lib
+dnl
+dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
+dnl to install symbolic links to the rel/abi versions of shared libraries.
+dnl
+dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
+dnl version when making symbolic links.
+dnl
+dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
+dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
+dnl (ex: libncurses.so.<ver>).
+dnl
+dnl Some loaders leave 'so_locations' lying around.  It is nice to clean up.

+# MKncurses_def.sh -- generate fallback definitions for ncurses_cfg.h

+# Author: Thomas E. Dickey 2000
+#
+# Given the choice between constructs such as
+#
+#	#if defined(foo) && foo
+#	#if foo
+#
+# we chose the latter.  It is guaranteed by the language standard, and there
+# appear to be no broken compilers that do not honor that detail.  But some
+# people want to use gcc's -Wundef option (corresponding to one of the less
+# useful features in Watcom's compiler) to check for misspellings.  So we
+# generate a set of fallback definitions to quiet the warnings without making
+# the code ugly.

+    `make' implicit rules from creating a file called install from it
+    when there is no Makefile.
+
+    This script is compatible with the BSD install script, but was written
+    from scratch.  It can only install one file at a time, a restriction
+    shared with many OS's install programs.

+The intention of the demo at this point in time is not to demonstrate all
+the features of (n)curses and its subsystems, but to give some sample
+sources how to use the binding at all.
+
+Ideally in the future we can combine both goals.

+#HELP
+#HELPKEYS
+You may scroll with the Cursor Up/Down Keys.
+You may leave the help with the Function Key labeled 'Quit'.
+#INHELP
+You are already in the help system.
+You may leave the help with the Function Key labeled 'Quit'.
+#MAIN
+This is the main menu of the sample program for the ncurses Ada95
+binding. The main intention of the demo is not to demonstrate or
+test all the features of ncurses and its subsystems, but to provide
+to you some sample code how to use the binding with Ada95.
+
+You may select this options:
+
+   * Look at some ncurses core functions
+   * Look at some features of the menu subsystem
+   * Look at some features of the form subsystem
+   * Look at the output of the Ada.Text_IO like functions
+     for ncurses.
+
+#MAINPAD
+You may press at any place in this demo CTRL-C. This will give you a command
+window. You can just type in the Label-String of a function key, then this
+key will be simulated. This should help you to run the application even if
+you run it on a terminal with no or only a few function keys. With CTRL-N
+and CTRL-P you may browse through the possible values in the command window.
+#MENU00
+Here we give you a selection of various menu demonstrations.
+#MENU-PAD00
+This menu itself is a demo for a single valued, 1-column menu with
+descriptions for the items, a marker and a padding character between
+the item name and the description.
+#MENU01
+This is a demo of the some of the menu layout options. One of them
+is the spacing functionality. Just press the Key labeled "Flip" to
+flip between the non-spaced and a spaced version of the menu. Please
+note that this functionality is unique for ncurses and is not found
+in the SVr4 menu implementation.
+
+This is a menu that sometimes does not fit into its window and
+therefore it becomes a scroll menu.
+
+You can also see here very nicely the pattern matching functionality
+of menus. Type for example a 'J' and you will be positioned to the
+next item after the current starting with a 'J'. Any more characters
+you type in make the pattern more specific. With CTRL-A and CTRL-Z
+(for more details press the Key labeled "Keys") you can browse
+through all the items matching the pattern.
+
+You may change the format of the menu. Just press one of the keys
+labeled "4x1", "4x2" or "4x3" to get a menu with that many rows
+and columns.
+
+With the Keys "O-Row" or "O-Col" (they occupy the same label and
+switch on selection) you can change the major order scheme for
+the menu. If "O-Col" is visible, the menu is currently major
+ordered by rows, you can switch to major column order by pressing
+the key. If "O-Row" is visible, it is just the reverse situation.
+This Key is not visible in "4x1" layout mode, because in this case
+the functionality makes no sense.
+
+With the Keys "Multi" or "Singl" (they occupy the same label and
+switch on selection) you can change whether or not the menu allows
+multiple or only single selection.
+
+With the Keys "+Desc" or "-Desc" (they occupy the same label and
+switch on selection) you can change whether or not the descriptions
+for each item should be displayed. Please not that this key is
+not visible in the "4x3" layout mode, because in this case the
+menu would not fit on a typical 80x24 screen.
+
+With the Keys "Disab" or "Enab" (they occupy the same label and
+switch on selection) you can dis- or enable the selectability of
+the month with 31 days.
+#MENU-PAD01
+You may press "Flip" to see the effect of ncurses unique menu-spacing.
+The Keys "4x1", "4x2" and "4x3" will change the format of the menu.
+Please note that this is a scrolling menu. You may also play with the
+pattern matching functionality or try to change the format of the menu.
+For more details press the Key labeled "Help".
+#FORM00
+This is a demo of the forms package.
+#FORM-PAD00
+Please note that this demo is far from being complete. It really shows
+only a small part of the functionality of the forms package. Let's hope
+the next version will have a richer demo (You want to contribute ?).
+#NOTIMPL
+Sorry this functionality of the demo is not implemented at the moment.
+Remember this is a freeware project, so I can use only my very rare
+free time to continue coding. If you would like to contribute, you
+are very welcome !
+#CURSES00
+This is a menu where you can select some different demos of the ncurses
+functionality.
+#CURSES-PAD00
+Please note that this demo is far from being complete. It really shows
+only a small part of the functionality of the curses package. Let's hope
+the next version will have a richer demo (You want to contribute ?).
+#MOUSEKEYS
+In this demo you may use this keys:
+
+   - Key labeled "Help"  to get a help
+   - Key labeled "Keys"  is what you are reading now
+   - Key labeled "Quit"  to leave the demo
+
+You may click the mouse buttons at any location at the screen and look
+at the protocol window !
+#MOUSE00
+A rather simple use of a mouse as demo. It is there just to test the
+code and to provide the sample source.
+
+It might be of interest, that the output into the protocol window is
+done by the (n)curses Text_IO subpackages. Especially the output of
+the button and state names is done by Ads's enumeration IO, which
+allows you to print the names of enumeration literals. That's really
+nice.
+#MOUSE-PAD00
+This is a very simple demo of the mouse features of ncurses. It is there
+just to test whether or not the generated code for the binding really
+works on the different architectures (seems so).
+#ATTRIBDEMO
+Again this is a more than simple demo and just here to give you the
+sourcecode.
+#ATTRIBKEYS
+You may press one of the three well known standard keys of this demo.
+#ATTRIB-PAD00
+Again this is a more than simple demo and just here to give you the
+source code. Feel free to contribute more.
+#TEXTIO
+#TEXTIOKEYS
+#TEXTIO-PAD00

+             How to install Ncurses/Terminfo on your system
+---------------------------------------------------------------------
+
+    ************************************************************
+    * READ ALL OF THIS FILE BEFORE YOU TRY TO INSTALL NCURSES. *
+    ************************************************************
+
+You should be reading the file INSTALL in a directory called ncurses-d.d, where
+d.d is the current version number.  There should be several subdirectories,
+including `c++', `form', `man', `menu', 'misc', `ncurses', `panel', `progs',
+and `test'.  See the README file for a roadmap to the package.
+
+If you are a distribution integrator or packager, please read and act on the
+section titled FOR SYSTEM INTEGRATORS below.
+
+If you are converting from BSD curses and do not have root access, be sure
+to read the BSD CONVERSION NOTES section below.
+
+If you are trying to build applications using gpm with ncurses,
+read the USING NCURSES WITH GPM section below.
+
+If you are cross-compiling, see the note below on BUILDING WITH A CROSS-COMPILER.
+
+If you want to build the Ada95 binding, go to the Ada95 directory and
+follow the instructions there.  The Ada95 binding is not covered below.
+
+
+REQUIREMENTS:
+------------
+
+You will need the following to build and install ncurses under UNIX:
+
+	* ANSI C compiler  (gcc, for instance)
+	* sh               (bash will do)
+	* awk              (mawk or gawk will do)
+	* sed
+	* BSD or System V style install (a script is enclosed)
+
+Ncurses has been also built in the OS/2 EMX environment.
+
+
+INSTALLATION PROCEDURE:
+----------------------
+
+1.  First, decide whether you want ncurses to replace your existing library (in
+    which case you'll need super-user privileges) or be installed in parallel
+    with it.
+
+    The --prefix option to configure changes the root directory for installing
+    ncurses.  The default is normally in subdirectories of /usr/local, except
+    for systems where ncurses is normally installed as a system library (see
+    "IF YOU ARE A SYSTEM INTEGRATOR").  Use --prefix=/usr to replace your
+    default curses distribution.
+
+    The package gets installed beneath the --prefix directory as follows:
+
+    In $(prefix)/bin:          tic, infocmp, captoinfo, tset,
+				reset, clear, tput, toe, tabs
+    In $(prefix)/lib:          libncurses*.* libcurses.a
+    In $(prefix)/share/terminfo: compiled terminal descriptions
+    In $(prefix)/include:      C header files
+    Under $(prefix)/man:       the manual pages
+
+    Note that the configure script attempts to locate previous installation of
+    ncurses, and will set the default prefix according to where it finds the
+    ncurses headers.
+
+    Do not use commands such as
+
+	make install prefix=XXX
+
+    to change the prefix after configuration, since the prefix value is used
+    for some absolute pathnames such as TERMINFO.  Instead do this
+
+	make install DESTDIR=XXX
+
+    See also the discussion of --with-install-prefix.
+
+2.  Type `./configure' in the top-level directory of the distribution to
+    configure ncurses for your operating system and create the Makefiles.
+    Besides --prefix, various configuration options are available to customize
+    the installation; use `./configure --help' to list the available options.
+
+    If your operating system is not supported, read the PORTABILITY section in
+    the file ncurses/README for information on how to create a configuration
+    file for your system.
+
+    The `configure' script generates makefile rules for one or more object
+    models and their associated libraries:
+
+	libncurses.a (normal)
+
+	libcurses.a (normal, a link to libncurses.a)
+		This gets left out if you configure with --disable-overwrite.
+
+	libncurses.so (shared)
+
+	libncurses_g.a (debug)
+
+	libncurses_p.a (profile)
+
+	libncurses.la (libtool)
+
+    If you configure using the --enable-widec option, a "w" is appended to the
+    library names (e.g., libncursesw.a), and the resulting libraries support
+    wide-characters, e.g., via a UTF-8 locale.  The corresponding header files
+    are compatible with the non-wide-character configuration; wide-character
+    features are provided by ifdef's in the header files.  The wide-character
+    library interfaces are not binary-compatible with the non-wide-character
+    version.  Building and running the wide-character code relies on a fairly
+    recent implementation of libiconv.  We have built this configuration on
+    various systems using libiconv, sometimes requiring libutf8.
+
+    If you configure using the --with-pthread option, a "t" is appended to
+    the library names (e.g., libncursest.a, libncursestw.a).
+
+    If you do not specify any models, the normal and debug libraries will be
+    configured.  Typing `configure' with no arguments is equivalent to:
+
+	./configure --with-normal --with-debug --enable-overwrite
+
+    Typing
+
+	./configure --with-shared
+
+    makes the shared libraries the default, resulting in
+
+	./configure --with-shared --with-normal --with-debug --enable-overwrite
+
+    If you want only shared libraries, type
+
+	./configure --with-shared --without-normal --without-debug
+
+    Rules for generating shared libraries are highly dependent upon the choice
+    of host system and compiler.  We've been testing shared libraries on
+    several systems, but more work needs to be done to make shared libraries
+    work on other systems.
+
+    If you have libtool installed, you can type
+
+	./configure --with-libtool
+
+    to generate the appropriate static and/or shared libraries for your
+    platform using libtool.
+
+    You can make curses and terminfo fall back to an existing file of termcap
+    definitions by configuring with --enable-termcap.  If you do this, the
+    library will search /etc/termcap before the terminfo database, and will
+    also interpret the contents of the TERM environment variable.  See the
+    section BSD CONVERSION NOTES below.
+
+3.  Type `make'.  Ignore any warnings, no error messages should be produced.
+    This should compile the ncurses library, the terminfo compiler tic(1),
+    captoinfo(1), infocmp(1), toe(1), clear(1) tset(1), reset(1), and tput(1)
+    programs (see the manual pages for explanation of what they do), some test
+    programs, and the panels, menus, and forms libraries.
+
+4.  Run ncurses and several other test programs in the test directory to
+    verify that ncurses functions correctly before doing an install that
+    may overwrite system files.  Read the file test/README for details on
+    the test programs.
+
+    NOTE: You must have installed the terminfo database, or set the
+    environment variable $TERMINFO to point to a SVr4-compatible terminfo
+    database before running the test programs.  Not all vendors' terminfo
+    databases are SVr4-compatible, but most seem to be.
+
+    It is possible to configure ncurses to use other terminfo database formats.
+    A few are provided as examples in the include-directory (see --with-caps).
+
+    If you run the test programs WITHOUT installing terminfo, ncurses may
+    read the termcap file and cache that in $HOME/.terminfo, which will
+    thereafter be used instead of the terminfo database.  See the comments
+    on "--enable-getcap-cache", to see why this is a Bad Thing.
+
+    The ncurses program is designed specifically to test the ncurses library.
+    You can use it to verify that the screen highlights work correctly, that
+    cursor addressing and window scrolling works OK, etc.
+
+5.  Once you've tested, you can type `make install' to install libraries,
+    the programs, the terminfo database and the manual pages.  Alternately, you
+    can type `make install' in each directory you want to install.  In the
+    top-level directory, you can do a partial install using these commands:
+
+	'make install.progs'    installs tic, infocmp, etc...
+	'make install.includes' installs the headers.
+	'make install.libs'     installs the libraries (and the headers).
+	'make install.data'     installs the terminfo data. (Note: `tic' must
+				be installed before the terminfo data can be
+				compiled).
+	'make install.man'      installs the manual pages.
+
+  ############################################################################
+  #     CAVEAT EMPTOR: `install.data' run as root will NUKE any existing     #
+  #  terminfo database. If you have any custom or unusual entries SAVE them  #
+  #  before you install ncurses.                                             #
+  ############################################################################
+
+    The terminfo(5) manual page must be preprocessed with tbl(1) before
+    being formatted by nroff(1).  Modern man(1) implementations tend to do
+    this by default, but you may want to look at your version's manual page
+    to be sure.  You may also install the manual pages after preprocessing
+    with tbl(1) by specifying the configure option --with-manpage-tbl.
+
+    If the system already has a curses library that you need to keep using
+    you'll need to distinguish between it and ncurses.  See the discussion of
+    --disable-overwrite.  If ncurses is installed outside the standard
+    directories (/usr/include and /usr/lib) then all your users will need to
+    use the -I option to compile programs and -L to link them.
+
+    If you have another curses installed in your system and you accidentally
+    compile using its curses.h you'll end up with a large number of
+    undefined symbols at link time.
+
+    IF YOU DO NOT HAVE ROOT: Change directory to the `progs' subdirectory
+    and run the `capconvert' script.  This script will deduce various things
+    about your environment and use them to build you a private terminfo tree,
+    so you can use ncurses applications.
+
+    If more than one user at your site does this, the space for the duplicate
+    trees is wasted.  Try to get your site administrators to install a system-
+    wide terminfo tree instead.
+
+    See the BSD CONVERSION NOTES section below for a few more details.
+
+6.  The c++ directory has C++ classes that are built on top of ncurses and
+    panels.  You must have c++ (and its libraries) installed before you can
+    compile and run the demo.
+
+    Use --without-cxx-binding to tell configure to not build the C++ bindings
+    and demo.
+
+    If you do not have C++, you must use the --without-cxx option to tell
+    the configure script to not attempt to determine the type of 'bool'
+    which may be supported by C++.  IF YOU USE THIS OPTION, BE ADVISED THAT
+    YOU MAY NOT BE ABLE TO COMPILE (OR RUN) NCURSES APPLICATIONS WITH C++.
+
+
+CONFIGURE OPTIONS:
+-----------------
+
+    The configure script provides a short list of its options when you type
+
+	./configure --help
+
+    The --help and several options are common to all configure scripts that are
+    generated with autoconf.  Those are all listed before the line
+
+	--enable and --with options recognized:
+
+    The other options are specific to this package.  We list them in alphabetic
+    order.
+
+    --disable-assumed-color
+	With ncurses 5.1, we introduced a new function, assume_default_colors()
+	which allows applications to specify what the default foreground and
+	background color are assumed to be.  Most color applications use
+	full-screen color; but a few do not color the background.  While the
+	assumed values can be overridden by invoking assume_default_colors(),
+	you may find it useful to set the assumed values to the pre-5.1
+	convention, using this configure option.
+
+    --disable-big-core
+	Assume machine has little memory.  The configure script attempts to
+	determine if your machine has enough memory (about 6Mb) to compile the
+	terminfo database without writing portions to disk.  Some allocators
+	return deceptive results, so you may have to override the configure
+	script.  Or you may be building tic for a smaller machine.
+
+    --disable-big-strings
+	Disable compile-time optimization of predefined tables which puts
+	all of their strings into a very long string, to reduce relocation
+	overhead.
+
+    --disable-database
+	Use only built-in data.  The ncurses libraries normally read terminfo
+	and termcap data from disk.  You can configure ncurses to have a
+	built-in database, aka "fallback" entries.  Embedded applications may
+	have no need for an external database.  Some, but not all of the
+	programs are useful in this configuration, e.g., tset and tput versus
+	infocmp and tic.
+
+    --disable-db-install
+	Do not install the terminal database.  This is used to omit features
+	for packages, as done with --without-progs.
+
+    --disable-echo
+	Use the option --disable-echo to make the build-log less verbose by
+	suppressing the display of the compile and link commands.  This makes
+	it easier to see the compiler warnings.  (You can always use "make -n"
+	to see the options that are used).
+
+    --disable-ext-funcs
+	Disable function-extensions.  Configure ncurses without the functions
+	that are not specified by XSI.  See ncurses/modules for the exact
+	list of library modules that would be suppressed.
+
+    --disable-gnat-projects
+	Disable GNAT projects even if usable, for testing old makefile rules.
+
+    --disable-hashmap
+	Compile without hashmap scrolling-optimization code.  This algorithm is
+	the default.
+
+    --disable-home-terminfo
+	The $HOME/.terminfo directory is normally added to ncurses' search
+	list for reading/writing terminfo entries, since that directory is
+	more likely writable than the system terminfo database.  Use this
+	option to disable the feature altogether.
+
+    --disable-largefile
+	Disable compiler flags needed to use large-file interfaces.
+
+    --disable-leaks
+	For testing, compile-in code that frees memory that normally would not
+	be freed, to simplify analysis of memory-leaks.
+
+	Any implementation of curses must not free the memory associated with
+	a screen, since (even after calling endwin()), it must be available
+	for use in the next call to refresh().  There are also chunks of
+	memory held for performance reasons.  That makes it hard to analyze
+	curses applications for memory leaks.  To work around this, build a
+	debugging version of the ncurses library which frees those chunks
+	which it can, and provides the _nc_free_and_exit() function to free
+	the remainder and then exit.  The ncurses utility and test programs
+	use this feature, e.g., via the ExitProgram() macro.
+
+	Because this lies outside of the library's intended usage, it is not
+	normally considered part of the ABI.  If there were some (as yet
+	unplanned) extension which frees memory in a manner that would let the
+	library resume and reallocate memory, then that would not use a "_nc_"
+	prefix.
+
+    --disable-lib-suffixes
+	Suppress the "w", "t" or "tw" suffixes which normally would be added
+	to the library names for the --enable-widec and --with-pthread options.
+
+    --disable-libtool-version
+	when using --with-libtool, control how the major/minor version numbers
+	are used for constructing the library name.
+
+	The default uses the -version-number feature of libtool, which makes
+	the library names compatible (though not identical) with the standard
+	build using --with-shared.
+
+	Use --disable-libtool-version to use the libtool -version-info feature.
+	This corresponds to the setting used before patch 20100515.
+
+	Starting with patch 20141115, using this option causes the configure
+	script to apply the top-level VERSION file to the ABI version used
+	for libtool.
+
+    --disable-lp64
+	The header files will ignore use of the _LP64 symbol to make chtype
+	and mmask_t types 32 bits (they may be long on 64-bit hosts, for
+	compatibility with older releases).
+
+	NOTE: this is potentially an ABI change, depending on existing
+	packages.  The default for this option is "disabled" for ncurses
+	ABI 5, and "enabled" for ABI 6.
+
+    --disable-macros
+	For testing, use functions rather than macros.  The program will run
+	more slowly, but it is simpler to debug.  This defines NCURSES_NOMACROS
+	at build time.  See also the --enable-expanded option.
+
+    --disable-overwrite
+	If you are installing ncurses on a system which contains another
+	development version of curses, or which could be confused by the loader
+	for another version, we recommend that you leave out the link to
+	-lcurses.  The ncurses library is always available as -lncurses.
+	Disabling overwrite also causes the ncurses header files to be
+	installed into a subdirectory, e.g., /usr/local/include/ncurses,
+	rather than the include directory.  This makes it simpler to avoid
+	compile-time conflicts with other versions of curses.h
+
+	Putting the header files into a subdirectory assumes that applications
+	will follow the (standard) practice of including the headers with
+	reference to the subdirectory name.  For instance, the normal ncurses
+	header would be included using
+
+		#include <ncurses/curses.h>
+		#include <ncurses/term.h>
+
+	while the ncursesw headers would be found this way:
+
+		#include <ncursesw/curses.h>
+		#include <ncursesw/term.h>
+
+	In either case (with or without the --disable-overwrite option),
+	almost all applications are designed to include a related set of
+	curses header files from the same directory.
+
+	Manipulating the --includedir configure option to put header files
+	directly in a subdirectory of the normal include-directory defeats
+	this, and breaks builds of portable applications.  Likewise, putting
+	some headers in /usr/include, and others in a subdirectory is a good
+	way to break builds.
+
+	When configured with --disable-overwrite, the installed header files'
+	embedded #include's are adjusted to use the same style of includes
+	noted above.  In particular, the unctrl.h header is included from
+	curses.h, which means that a makefile which tells the compiler to
+	include directly from the subdirectory will fail to compile correctly.
+	Without some special effort, it will either fail to compile at all,
+	or the compiler may find a different unctrl.h file.
+
+	In addition to the curses library, a system may provide its own
+	versions of the add-on libraries (form, menu, panel), which would
+	not be compatible with ncurses.  These options allow you to rename
+	ncurses' add-on libraries to avoid conflicts when linking:
+
+		--with-form-libname=XXX
+		--with-menu-libname=XXX
+		--with-panel-libname=XXX
+
+	Rather than renaming them abitrarily, a prefix or suffix is
+	recommended.  An "n" prefix provides consistency with ncurses versus
+	curses, i.e.,
+
+		--with-form-libname=nform
+		--with-menu-libname=nmenu
+		--with-panel-libname=npanel
+
+    --disable-pkg-ldflags
+	Omit options in $LDFLAGS and $EXTRA_LDFLAGS from the pkg-config ".pc"
+	and corresponding ncurses*-config script which normally are listed via
+	the "--libs" option.  These options are normally used to facilitate
+	linking to ncurses when it was configured to use the rpath feature.
+
+	See also --enable-rpath and --disable-rpath-hack.
+
+    --disable-relink
+	If --enable-rpath is given, the generated makefiles normally will
+	rebuild shared libraries during install.  Use this option to simply
+	copy whatever the linker produced.
+
+	Static libraries cannot simply be copied because tools use timestamps
+	to determine if the library's symbol table is up to date.  If your
+	install program supports the "-p" (preserve timestamp) option, that
+	is used when --disable-relink is given, to avoid rebuilding the symbol
+	table.
+
+	Finally, some tools ignore the subsecond timestamps supported by some
+	filesystems.  This option adds a 1-second sleep to help those tools
+	avoid unnecessary relinking during the install process.
+
+    --disable-root-access
+	Compile with environment restriction, so most file-access is limited
+	when running via a setuid/setgid application.
+
+    --disable-root-environ
+	Compile with environment restriction, so certain environment variables
+	are not available when running as root, or via a setuid/setgid
+	application.  These are (for example $TERMINFO) those that allow the
+	search path for the terminfo or termcap entry to be customized.
+
+    --disable-rpath-hack
+	Normally the configure script helps link libraries found in unusual
+	places by adding an rpath option to the link command.  If you are
+	building packages, this feature may be redundant.  Use this option
+	to suppress the feature.
+
+    --disable-scroll-hints
+	Compile without scroll-hints code.  This option is ignored when
+	hashmap scrolling is configured, which is the default.
+
+    --disable-stripping
+	Do not strip installed executables.
+
+    --disable-tic-depends
+	When building shared libraries, normally the tic library is linked to
+	depend upon the ncurses library (or equivalently, on the tinfo-library
+	if the --with-termlib option was given).  The tic- and tinfo-library
+	ABIs do not depend on the --enable-widec option.  Some packagers have
+	used this to reduce the number of library files which are packaged by
+	using only one copy of those libraries.  To make this work properly,
+	the tic library must be built without an explicit dependency on the
+	underlying library (ncurses vs ncursesw, tinfo vs tinfow).  Use this
+	configure option to do that.
+	For example
+		configure --with-ticlib --with-shared --disable-tic-depends
+
+    --disable-tparm-varargs
+	Portable programs should call tparm() using the fixed-length parameter
+	list documented in X/Open.  ncurses provides varargs support for this
+	function.  Use --disable-tparm-varargs to disable this support.
+
+    --enable-assertions
+	For testing, compile-in assertion code.  This is used only for a few
+	places where ncurses cannot easily recover by returning an error code.
+
+    --enable-broken_linker
+	A few platforms have what we consider a broken linker:  it cannot link
+	objects from an archive solely by referring to data objects in those
+	files, but requires a function reference.  This configure option
+	changes several data references to functions to work around this
+	problem.
+
+	NOTE: With ncurses 5.1, this may not be necessary, since we are
+	told that some linkers interpret uninitialized global data as a
+	different type of reference which behaves as described above.  We have
+	explicitly initialized all of the global data to work around the
+	problem.
+
+    --enable-bsdpad
+	Recognize BSD-style prefix padding.  Some ancient BSD programs (such as
+	nethack) call tputs("50") to implement delays.
+
+    --enable-colorfgbg
+	Compile with experimental $COLORFGBG code.  That environment variable
+	is set by some terminal emulators as a hint to applications, by
+	advertising the default foreground and background colors.  During
+	initialization, ncurses sets color pair 0 to match this.
+
+    --enable-const
+	The curses interface as documented in XSI is rather old, in fact
+	including features that precede ANSI C.  The prototypes generally do
+	not make effective use of "const".  When using stricter compilers (or
+	gcc with appropriate warnings), you may see warnings about the mismatch
+	between const and non-const data.  We provide a configure option which
+	changes the interfaces to use const - quieting these warnings and
+	reflecting the actual use of the parameters more closely.  The ncurses
+	library uses the symbol NCURSES_CONST for these instances of const,
+	and if you have asked for compiler warnings, will add gcc's const-qual
+	warning.  There will still be warnings due to subtle inconsistencies
+	in the interface, but at a lower level.
+
+	NOTE: configuring ncurses with this option may detract from the
+	portability of your applications by encouraging you to use const in
+	places where the XSI curses interface would not allow them.  Similar
+	issues arise when porting to SVr4 curses, which uses const in even
+	fewer places.
+
+    --enable-expanded
+	For testing, generate functions for certain macros to make them visible
+	as such to the debugger.  See also the --disable-macros option.
+
+    --enable-exp-win32
+	When configuring for MinGW, use the experimental Windows 10 driver.
+
+    --enable-ext-colors
+	Extend the cchar_t structure to allow more than 16 colors to be
+	encoded.  This applies only to the wide-character (--enable-widec)
+	configuration.
+
+	NOTE: using this option will make libraries which are not binary-
+	compatible with libncursesw 5.4.  None of the interfaces change, but
+	applications which have an array of cchar_t's must be recompiled.
+
+    --enable-ext-mouse
+	Modify the encoding of mouse state to make room for a 5th mouse button.
+	That allows one to use ncurses with a wheel mouse with xterm or
+	similar X terminal emulators.
+
+	NOTE: using this option will make libraries which are not binary-
+	compatible with libncursesw 5.4.  None of the interfaces change, but
+	applications which have mouse mask mmask_t's must be recompiled.
+
+    --enable-ext-putwin
+	Modify the file-format written by putwin() to use printable text rather
+	than binary files, allowing getwin() to read screen dumps written by
+	differently-configured ncurses libraries.  The extended getwin() can
+	still read binary screen dumps from the "same" configuration of
+	ncurses.  This does not change the ABI (the binary interface seen by
+	calling applications).
+
+    --enable-fvisibility
+    	Use the gcc "-fvisibility=hidden" option to make symbols which are not
+	explicitly exported, "hidden".  Doing this may reduce the number of
+	symbols exported in the C++ binding; it should have less effect on the
+	C libraries when symbol-versioning is used.
+
+    --enable-getcap
+	Use the 4.4BSD getcap code if available, or a bundled version of it to
+	fetch termcap entries.  Entries read in this way cannot use (make
+	cross-references to) the terminfo tree, but it is faster than reading
+	/etc/termcap.
+
+	If configured for one of the *BSD systems, this automatically uses
+	the hashed database system produced using cap_mkdb or similar tools.
+	In that case, there is no advantage in using the --enable-getcap-cache
+	option.
+
+	See also the --with-hashed-db option.
+
+    --enable-getcap-cache
+	Cache translated termcaps under the directory $HOME/.terminfo
+
+	NOTE: this sounds good - it makes ncurses run faster the second time.
+	But look where the data comes from - an /etc/termcap containing lots of
+	entries that are not up to date.  If you configure with this option and
+	forget to install the terminfo database before running an ncurses
+	application, you will end up with a hidden terminfo database that
+	generally does not support color and will miss some function keys.
+
+    --enable-hard-tabs
+	Compile-in cursor-optimization code that uses hard-tabs.  We would make
+	this a standard feature except for the concern that the terminfo entry
+	may not be accurate, or that your stty settings have disabled the use
+	of tabs.
+
+    --enable-interop
+	Compile-in experimental interop bindings.  These provide generic types
+	for the form-library.
+
+    --enable-mixed-case
+	Controls whether the filesystem on which the terminfo database resides
+	supports mixed-case filenames (normal for UNIX, but not on other
+	systems).  If you do not specify this option, the configure script
+	checks the current filesystem.
+
+    --enable-no-padding
+	Compile-in support for the $NCURSES_NO_PADDING environment variable,
+	which allows you to suppress the effect of non-mandatory padding in
+	terminfo entries.  This is the default, unless you have disabled the
+	extended functions.
+
+    --enable-opaque-curses
+    --enable-opaque-form
+    --enable-opaque-menu
+    --enable-opaque-panel
+	Define symbol in curses.h which controls whether some library
+	structures are treated as "opaque".  The --enable-opaque-curses option
+	is overridden by the --enable-reentrant option.
+
+    --enable-pc-files
+	If pkg-config is found (see --with-pkg-config), generate ".pc" files
+	for each of the libraries, and install them in pkg-config's library
+	directory.
+
+    --enable-pthreads-eintr
+	add logic in threaded configuration to ensure that a read(2) system
+	call can be interrupted for SIGWINCH.
+
+    --enable-reentrant
+	Compile configuration which improves reentrant use of the library by
+	reducing global and static variables.  This option is also set if
+	--with-pthread is used.
+
+	Enabling this option adds a "t" to the library names, except for the
+	special case when --enable-weak-symbols is also used.
+
+    --enable-rpath
+	Use rpath option when generating shared libraries, and (with some
+	restrictions) when linking the corresponding programs.  This originally
+	(in 1997) applied mainly to systems using the GNU linker (read the
+	manpage).
+
+	More recently it is useful for systems that require special treatment
+	shared libraries in "unusual" locations.  The "system" libraries reside
+	in directories which are on the loader's default search-path.  While
+	you may be able to use workarounds such as the $LD_LIBRARY_PATH
+	environment variable, they do not work with setuid applications since
+	the LD_LIBRARY_PATH variable would be unset in that situation.
+
+	This option does not apply to --with-libtool, since libtool makes
+	extra assumptions about rpath.
+
+    --enable-safe-sprintf
+	Compile with experimental safe-sprintf code.  You may consider using
+	this if you are building ncurses for a system that has neither
+	vsnprintf() or vsprintf().  It is slow, however, and is used only on
+	very old systems which lack vsnprintf().
+
+    --enable-signed-char
+	The term.h header declares a Booleans[] array typed "char".  But it
+	stores signed values there and "char" is not necessarily signed.
+	Some packagers choose to alter the type of Booleans[] though this
+	is not strictly compatible.  This option allows one to implement this
+	alteration without patching the source code.
+
+    --enable-sigwinch
+	Compile support for ncurses' SIGWINCH handler.  If your application has
+	its own SIGWINCH handler, ncurses will not use its own.  The ncurses
+	handler causes wgetch() to return KEY_RESIZE when the screen-size
+	changes.  This option is the default, unless you have disabled the
+	extended functions.
+
+    --enable-sp-funcs
+	Compile-in support for extended functions which accept a SCREEN pointer,
+	reducing the need for juggling the global SP value with set_term() and
+	delscreen().
+
+    --enable-stdnoreturn
+	When enabled, check if the <stdnoreturn.h> header exists, and if found
+	define GCC_NORETURN to _Noreturn rather than either the gcc-specific
+	__attribute__((noreturn)) or an empty token.  Doing this may require
+	calling programs which use GCC_NORETURN in their own function
+	definitions to be modified, because _Noreturn is only accepted as
+	the first token in a declaration.
+
+    --enable-string-hacks
+	Controls whether strlcat and strlcpy may be used.  The same issue
+	applies to OpenBSD's warnings about snprintf, noting that this function
+	is weakly standardized.
+
+	Aside from stifling these warnings, there is no functional improvement
+	in ncurses.
+
+    --enable-symlinks
+	If your system supports symbolic links, make tic use symbolic links
+	rather than hard links to save diskspace when writing aliases in the
+	terminfo database.
+
+    --enable-tcap-names
+	Compile-in support for user-definable terminal capabilities.  Use the
+	-x option of tic and infocmp to treat unrecognized terminal
+	capabilities as user-defined strings.  This option is the default,
+	unless you have disabled the extended functions.
+
+    --enable-term-driver
+	Enable experimental terminal-driver.  This is currently used for the
+	MinGW port, by providing a way to substitute the low-level terminfo
+	library with different terminal drivers.
+
+    --enable-termcap
+	Compile in support for reading terminal descriptions from termcap if no
+	match is found in the terminfo database.  See also the --enable-getcap
+	and --enable-getcap-cache options.
+
+	Termcap support requires run-time parsing rather than loading
+	predigested data.  If you have specified --with-ticlib, then you
+	cannot have termcap support since run-time parsing is done in the
+	tic library, which is intentionally not part of normal linkage
+	dependencies.
+
+    --enable-warnings
+	Turn on GCC compiler warnings.  There should be only a few.
+
+    --enable-wattr-macros
+	The 6.0 ABI adds support for extended colors and for extended mouse.
+	The former is a noticeable problem when developers inadvertently
+	compile using the ncurses6 header files and link with an ncurses5
+	library, because the wattr* macros use a new field in the WINDOW
+	structure.  These macros are used in several applications.
+
+	Since ncurses provides an actual function for each of these macros,
+	suppressing them from the curses.h header allows the ncurses5 libraries
+	to be used in most applications.
+
+	NOTE: The extended colors also are used in the cchar_t structure, but
+	fewer applications use that.
+
+	NOTE: This workaround does not help with mismatches in the ncurses
+	mouse version.  The extended mouse feature uses one less fewer bit for
+	each button, so that only the first button will work as expected with
+	a mismatch between header and library.  Again, most applications will
+	work, since most use only the first button.
+
+    --enable-weak-symbols
+	If the --with-pthread option is set, check if the compiler supports
+	weak-symbols.  If it does, then name the thread-capable library without
+	the "t" (libncurses rather than libncursest), and provide for
+	dynamically loading the pthreads entrypoints at runtime.  This allows
+	one to reduce the number of library files for ncurses.
+
+    --enable-wgetch-events
+	Compile with experimental wgetch-events code.  See ncurses/README.IZ
+
+    --enable-widec
+	Compile with wide-character code.  This makes a different version of
+	the libraries (e.g., libncursesw.so), which stores characters as
+	wide-characters,
+
+	NOTE: applications compiled with this configuration are not compatible
+	with those built for 8-bit characters.  You cannot simply make a
+	symbolic link to equate libncurses.so with libncursesw.so
+
+	NOTE: the Ada95 binding may be built against either version of the the
+	ncurses library, but you must decide which:  the binding installs the
+	same set of files for either version.  Currently (2002/6/22) it does
+	not use the extended features from the wide-character code, so it is
+	probably better to not install the binding for that configuration.
+
+    --enable-xmc-glitch
+	Compile-in support experimental xmc (magic cookie) code.
+
+    --with-abi-version=NUM
+	Override the ABI version, which is used in shared library filenames.
+	Normally this is the same as the release version; some ports have
+	special requirements for compatibility.
+
+	This option does not affect linking with libtool, which uses the
+	release major/minor numbers.
+
+    --with-ada-compiler=CMD
+	Specify the Ada95 compiler command (default "gnatmake")
+
+    --with-ada-include=DIR
+	Tell where to install the Ada includes (default:
+	PREFIX/lib/ada/adainclude)
+
+    --with-ada-libname=NAME
+	Override the name of the Ada binding (default: "AdaCurses")
+
+    --with-ada-objects=DIR
+	Tell where to install the Ada objects (default:  PREFIX/lib/ada/adalib)
+
+    --with-ada-sharedlib
+	Build a shared library for Ada95 binding, if the compiler permits.
+
+	NOTE: You must also set the --with-shared option on some platforms
+	for a successful build.  You need not use this option when you set
+	--with-shared, unless you want to use the Ada shared library.
+
+    --with-bool=TYPE
+	If --without-cxx is specified, override the type used for the "bool"
+	declared in curses.h (normally the type is automatically chosen to
+	correspond with that in <stdbool.h>, or defaults to platform-specific
+	sizes).
+
+    --with-build-cc=XXX
+	If cross-compiling, specify a host C compiler, which is needed to
+	compile a few utilities which generate source modules for ncurses.
+	If you do not give this option, the configure script checks if the
+	$BUILD_CC variable is set, and otherwise defaults to gcc or cc.
+
+    --with-build-cflags=XXX
+	If cross-compiling, specify the host C compiler-flags.  You might need
+	to do this if the target compiler has unusual flags which confuse the
+	host compiler.
+
+	You can also set the environment variable $BUILD_CFLAGS rather than
+	use this option.
+
+    --with-build-cpp=XXX
+	This option is provided by the same macro used for $BUILD_CC, etc.,
+	but is not directly used by ncurses.
+
+    --with-build-cppflags=XXX
+	If cross-compiling, specify the host C preprocessor-flags.  You might
+	need to do this if the target compiler has unusual flags which confuse
+	the host compiler.
+
+	You can also set the environment variable $BUILD_CPPFLAGS rather than
+	use this option.
+
+    --with-build-ldflags=XXX
+	If cross-compiling, specify the host linker-flags.  You might need to
+	do this if the target linker has unusual flags which confuse the host
+	compiler.
+
+	You can also set the environment variable $BUILD_LDFLAGS rather than
+	use this option.
+
+    --with-build-libs=XXX
+	If cross-compiling, the host libraries.  You might need to do this if
+	the target environment requires unusual libraries.
+
+	You can also set the environment variable $BUILD_LIBS rather than
+	use this option.
+
+    --with-caps=XXX
+	Specify an alternate terminfo capabilities file, which makes the
+	configure script look for "include/Caps.XXX".  A few systems, e.g.,
+	AIX 4.x use the same overall file-format as ncurses for terminfo
+	data, but use different alignments within the tables to support
+	legacy applications.  For those systems, you can configure ncurses
+	to use a terminfo database which is compatible with the native
+	applications.
+
+    --with-ccharw-max=XXX
+	Override the size of the wide-character array in cchar_t structures.
+	Changing this will alter the binary interface.  This defaults to 5.
+
+    --with-chtype=TYPE
+	Override type of chtype, which stores the video attributes and (if
+	--enable-widec is not given) a character.  Prior to ncurses 5.5, this
+	was always unsigned long, but with ncurses 5.5, it may be unsigned.
+	Use this option if you need to preserve compatibility with 64-bit
+	executables, e.g., by setting "--with-chtype=long" (the configure
+	script supplies "unsigned").
+
+    --with-config-suffix=XXX
+	Specify a suffix for the ncursesw6-config file, etc., used to work
+	around conflicts with packages.
+
+    --with-cxx-libname=NAME
+	Override the basename of the ncurses++ library (default: "ncurses++")
+
+    --with-cxx-shared
+	When --with-shared is set, build libncurses++ as a shared library.
+	This implicitly relies upon building with gcc/g++, since other
+	compiler suites may have differences in the way shared libraries are
+	built.  libtool by the way has similar limitations.
+
+    --with-database=XXX
+	Specify the terminfo source file to install.  Usually you will wish
+	to install ncurses' default (misc/terminfo.src).  Certain systems
+	have special requirements, e.g, OS/2 EMX has a customized terminfo
+	source file.
+
+    --with-dbmalloc
+	For testing, compile and link with Conor Cahill's dbmalloc library.
+	This also sets the --disable-leaks option.
+
+    --with-debug
+	Generate debug-libraries (default).  These are named by adding "_g"
+	to the root, e.g., libncurses_g.a
+
+    --with-default-terminfo-dir=XXX
+	Specify the default terminfo database directory.  This is normally
+	DATADIR/terminfo, e.g., /usr/share/terminfo.
+
+    --with-dmalloc
+	For testing, compile and link with Gray Watson's dmalloc library.
+	This also sets the --disable-leaks option.
+
+    --with-export-syms[=XXX]
+	Limit exported symbols using libtool.  The configure script
+	automatically chooses an appropriate ".sym" file, which lists the
+	symbols which are part of the ABI.
+
+    --with-extra-suffix[=XXX]
+	Add the given suffix to header- and library-names to simplify
+	installing incompatible ncurses libraries, e.g., those using a
+	different ABI.  The renaming affects the name of the
+	include-subdirectory if --disable-overwrite is given.
+
+    --with-fallbacks=XXX
+	Specify a list of fallback terminal descriptions which will be
+	compiled into the ncurses library.  See CONFIGURING FALLBACK ENTRIES.
+
+	See also "--with-tic-path" and "--with-infocmp-path".
+
+    --with-form-libname=NAME
+	Override the basename of the form library (default: "form")
+
+    --with-gpm
+	use Alessandro Rubini's GPM library to provide mouse support on the
+	Linux console.  Prior to ncurses 5.5, this introduced a dependency on
+	the GPM library.
+
+	Currently ncurses uses the dlsym() function to bind to the library at
+	runtime, so it is only necessary that the library be present when
+	ncurses is built, to obtain the filename (or soname) used in the
+	corresponding dlopen() call.  If you give a value for this option,
+	e.g.,
+
+		--with-gpm=$HOME/tmp/test-gpm.so
+
+	that overrides the configure check for the soname.
+
+	See also --without-dlsym
+
+    --with-hashed-db[=XXX]
+	Use a hashed database for storing terminfo data rather than storing
+	each compiled entry in a separate binary file within a directory
+	tree.
+
+	In particular, this uses the Berkeley database 1.8.5 interface, as
+	provided by that and its successors db 2, 3, and 4.  The actual
+	interface is slightly different in the successor versions of the
+	Berkeley database.  The database should have been configured using
+	"--enable-compat185".
+
+	If you use this option for configuring ncurses, tic will only be able
+	to write entries in the hashed database.  infocmp can still read
+	entries from a directory tree as well as reading entries from the
+	hashed database.  To do this, infocmp determines whether the $TERMINFO
+	variable points to a directory or a file, and reads the directory-tree
+	or hashed database respectively.
+
+	You cannot have a directory containing both hashed-database and
+	filesystem-based terminfo entries.
+
+	Use the parameter value to give the install-prefix used for the
+	database, e.g.,
+		--with-hashed-db=/usr/local/BigBase
+	to find the corresponding include- and lib-directories under the
+	given directory.  Alternatively, you can specify a directory leaf
+	name, e.g.,
+		--with-hashed-db=db4
+	to make the configure script look for files in a subdirectory such as
+		/usr/include/db4/db.h
+		/usr/lib/db4/libdb.so
+
+	See also the --enable-getcap option.
+
+    --with-infocmp-path[=XXX]
+	Use this option to override the automatic detection of tic in your
+	$PATH when building fallbacks (see "--with-fallbacks").
+
+    --with-install-prefix=XXX
+	Allows you to specify an alternate location for installing ncurses
+	after building it.  The value you specify is prepended to the "real"
+	install location.  This simplifies making binary packages.  The
+	makefile variable DESTDIR is set by this option.  It is also possible
+	to use
+		make install DESTDIR=XXX
+	since the makefiles pass that variable to subordinate makes.
+
+	NOTE: a few systems build shared libraries with fixed pathnames; this
+	option probably will not work for those configurations.
+
+    --with-lib-prefix=XXX
+	OS/2 EMX used a different naming convention from most Unix-like
+	platforms.  It required that the "lib" part of a library name was
+	omitted.  Newer EMX as part of eComStation does not follow that
+	convention.  Use this option to override the configure script's
+	assumptions about the library-prefix.  If this option is omitted, it
+	uses the original OS/2 EMX convention for that platform.  Use
+	"--with-lib-prefix=lib" for the newer EMX in eComStation.  Use
+	"--without-lib-prefix" to suppress it for other odd platforms.
+
+    --with-libtool[=XXX]
+	Generate libraries with libtool.  If this option is selected, then it
+	overrides all other library model specifications.  Note that libtool
+	must already be installed, uses makefile rules dependent on GNU make,
+	and does not promise to follow the version numbering convention of
+	other shared libraries on your system.  However, if the --with-shared
+	option does not succeed, you may get better results with this option.
+
+	If a parameter value is given, it must be the full pathname of the
+	particular version of libtool, e.g.,
+		/usr/bin/libtool-1.2.3
+
+	It is possible to rebuild the configure script to use the automake
+	macros for libtool, e.g., AC_PROG_LIBTOOL.  See the comments in
+	aclocal.m4 for CF_PROG_LIBTOOL, and ensure that you build configure
+	using the appropriate patch for autoconf from
+		https://invisible-island.net/autoconf/
+
+    --with-libtool-opts=XXX
+	Allow user to pass additional libtool options into the library creation
+	and link steps.  The main use for this is to do something like
+		./configure --with-libtool-opts=-static
+	to get the same behavior as automake-flavored
+		./configure --enable-static
+
+    --with-manpage-aliases
+	Tell the configure script you wish to create entries in the
+	man-directory for aliases to manpages which list them, e.g., the
+	functions in the panel manpage.  This is the default.  You can disable
+	it if your man program does this.  You can also disable
+	--with-manpage-symlinks to install files containing a ".so" command
+	rather than symbolic links.
+
+    --with-manpage-format=XXX
+	Tell the configure script how you would like to install man-pages.  The
+	option value must be one of these:  gzip, compress, BSDI, normal,
+	formatted.  If you do not give this option, the configure script
+	attempts to determine which is the case.
+
+    --with-manpage-renames=XXX
+	Tell the configure script that you wish to rename the manpages while
+	installing.  Currently the only distribution which does this is Debian.
+	The option value specifies the name of a file that lists the renamed
+	files, e.g., $srcdir/man/man_db.renames
+
+    --with-manpage-symlinks
+	Tell the configure script that you wish to make symbolic links in the
+	man-directory for aliases to the man-pages.  This is the default, but
+	can be disabled for systems that provide this automatically.  Doing
+	this on systems that do not support symbolic links will result in
+	copying the man-page for each alias.
+
+    --with-manpage-tbl
+	Tell the configure script that you wish to preprocess the manpages
+	by running them through tbl to generate tables understandable by
+	nroff.
+
+    --with-menu-libname=NAME
+	Override the basename of the menu library (default: "menu")
+
+    --with-mmask-t=TYPE
+	Override type of mmask_t, which stores the mouse mask.  Prior to
+	ncurses 5.5, this was always unsigned long, but with ncurses 5.5, it
+	may be unsigned.  Use this option if you need to preserve compatibility
+	with 64-bit executables.
+
+    --with-normal
+	Generate normal (i.e., static) libraries (default).
+
+	Note:  on Linux, the configure script will attempt to use the GPM
+	library via the dlsym() function call.  Use --without-dlsym to disable
+	this feature, or --without-gpm, depending on whether you wish to use
+	GPM.
+
+    --with-ospeed=TYPE
+	Override type of ospeed variable, which is part of the termcap
+	compatibility interface.  In termcap, this is a 'short', which works
+	for a wide range of baudrates because ospeed is not the actual speed
+	but the encoded value, e.g., B9600 would be a small number such as 13.
+	However the encoding scheme originally allowed for values "only" up to
+	38400bd.  A newer set of definitions past 38400bd is not encoded as
+	compactly, and is not guaranteed to fit into a short (see the function
+	cfgetospeed(), which returns a speed_t for this reason).  In practice,
+	applications that required knowledge of the ospeed variable, i.e.,
+	those using termcap, do not use the higher speeds.  Your application
+	(or system, in general) may or may not.
+
+    --with-panel-libname=NAME
+	Override the basename of the panel library (default: "panel")
+
+    --with-pc-suffix=SUFFIX
+	If ".pc" files are installed, optionally add a suffix to the files
+	and corresponding package names to separate unusual configurations.
+	If no option value is given (or if it is "none"), no suffix is added.
+
+    --with-pcre2
+	Add PCRE2 (Perl-compatible regular expressions v2) to the build if it
+	is available and the user requests it.  Assume the application will
+	otherwise use the POSIX interface.
+
+	This is useful for MinGW builds because the usual POSIX interface is
+	not supplied by the development environment, while ncurses' form
+	library uses a regular expression feature for one of the field types.
+
+    --with-pkg-config=[DIR]
+	Check for pkg-config, optionally specifying its path.
+
+    --with-pkg-config-libdir=[DIR]
+	If pkg-config was found, override the automatic check for its library
+	path.  The configure script allows only a single directory, because
+	that is used as the directory in which to install ".pc" files.
+
+	The automatic check for the library path prefers the first directory
+	which currently exists.  If none of the directories listed by
+	pkg-config exist, the check prefers a pkgconfig directory under the
+	"libdir" set by the configure script (which may not be the system
+	default), or if pkg-config lists nothing suitable, the first one which
+	is listed by pkg-config is used.
+
+	Automatic selection is overridden by providing an option-value
+	beginning with "/".
+
+	If this option is omitted, the default directory for installing
+	".pc" files is ${libdir}/pkgconfig
+
+    --with-profile
+	Generate profile-libraries These are named by adding "_p" to the root,
+	e.g., libncurses_p.a
+
+    --with-pthread
+	Link with POSIX threads, set --enable-reentrant.  The use_window() and
+	use_screen() functions will use mutex's, allowing rudimentary support
+	for multithreaded applications.
+
+    --with-rcs-ids
+	Compile-in RCS identifiers.  Most of the C files have an identifier.
+
+    --with-rel-version=NUM
+	Override the release version, which may be used in shared library
+	filenames.  This consists of a major and minor version number separated
+	by ".".  Normally the major version number is the same as the ABI
+	version; some ports have special requirements for compatibility.
+
+    --with-shared
+	Generate shared-libraries.  The names given depend on the system for
+	which you are building, typically using a ".so" suffix, along with
+	symbolic links that refer to the release version.
+
+	NOTE: Unless you override the configure script by setting the $CFLAGS
+	environment variable, these will not be built with the -g debugging
+	option.
+
+	NOTE: For some configurations, e.g., installing a new version of
+	ncurses shared libraries on a machine which already has ncurses
+	shared libraries, you may encounter problems with the linker.
+	For example, it may prevent you from running  the build tree's
+	copy of tic (for installing the terminfo database) because it
+	loads the system's copy of the ncurses shared libraries.
+
+	In that case, using the misc/shlib script may be helpful, since it
+	sets $LD_LIBRARY_PATH to point to the build tree, e.g.,
+
+		./misc/shlib make install
+
+	Alternatively, for most platforms, the linker accepts a list of
+	directories which will be searched for libraries at run-time.  The
+	configure script allows you to modify this list using the
+	RPATH_LIST environment variable.  It is a colon-separated list of
+	directories (default:  the "libdir" set via the configure script).
+	If you set that to put "../lib" first in the list, the linker will
+	look first at the build-directory, and avoid conflict with libraries
+	already installed.  One drawback to this approach is that libraries
+	can be accidentally searched in any "../lib" directory.
+
+	NOTE: If you use the --with-ada-sharedlib option, you should also
+	set this option, to ensure that C-language modules needed for the
+	Ada binding use appropriate compiler options.
+
+    --with-shlib-version=XXX
+	Specify whether to use the release or ABI version for shared libraries.
+	This is normally chosen automatically based on the type of system
+	which you are building on.  We use it for testing the configure script.
+
+    --with-sysmouse
+	use FreeBSD sysmouse interface provide mouse support on the console.
+
+    --with-system-type=XXX
+	For testing, override the derived host system-type which is used to
+	decide things such as the linker commands used to build shared
+	libraries.  This is normally chosen automatically based on the type of
+	system which you are building on.  We use it for testing the configure
+	script.
+
+    --with-terminfo-dirs=XXX
+	Specify a search-list of terminfo directories which will be compiled
+	into the ncurses library (default: DATADIR/terminfo)
+
+	This is a colon-separated list, like the TERMINFO_DIRS environment
+	variable.
+
+    --with-termlib[=XXX]
+	When building the ncurses library, organize this as two parts:  the
+	curses library (libncurses) and the low-level terminfo library
+	(libtinfo).  This is done to accommodate applications that use only
+	the latter.  The terminfo library is about half the size of the total.
+
+	If an option value is given, that overrides the name of the terminfo
+	library.  For instance, if the wide-character version is built, the
+	terminfo library would be named libtinfow.  But the libtinfow interface
+	is upward compatible from libtinfo, so it would be possible to overlay
+	libtinfo.so with a "wide" version of libtinfow.so by renaming it with
+	this option.
+
+    --with-termpath=XXX
+	Specify a search-list of termcap files which will be compiled into the
+	ncurses library (default:  /etc/termcap:/usr/share/misc/termcap)
+
+    --with-tic-path[=XXX]
+	Use this option to override the automatic detection of tic in your
+	$PATH when building fallbacks (see "--with-fallbacks").
+
+    --with-ticlib[=XXX]
+	When building the ncurses library, build a separate library for
+	the modules that are used only by the utility programs.  Normally
+	those would be bundled with the termlib or ncurses libraries.
+
+	If an option value is given, that overrides the name of the tic
+	library.  As in termlib, there is no ABI difference between the
+	"wide" libticw.so and libtic.so
+
+	NOTE: Overriding the name of the tic library may be useful if you are
+	also using the --with-termlib option to rename libtinfo.  If you are
+	not doing that, renaming the tic library can result in conflicting
+	library dependencies for tic and other programs built with the tic
+	library.
+
+    --with-tparm-arg[=XXX]
+	Override the type used for tparm() arguments, which normally is a
+	"long".  However the function must assume that its arguments can hold a
+	pointer to char's which is not always workable for 64-bit platforms.  A
+	better choice would be intptr_t, which was not available at the time
+	tparm's interface was defined.
+
+	If the option is not given, this defaults to "long".
+
+    --with-trace
+	Configure the trace() function as part of the all models of the ncurses
+	library.  Normally it is part of the debug (libncurses_g) library only.
+
+    --with-valgrind
+	For testing, compile with debug option.
+	This also sets the --disable-leaks option.
+
+    --with-versioned-syms[=XXX]
+	The Solaris, GNU and reportedly some other linkers (ld) accept a
+	"--version-script" option which tells the linker to annotate the
+	resulting objects with version identifiers.
+
+	Use "objdump -T" on a library to see the annotations.
+
+	The configure script attempts to automatically apply a suitable ".map"
+	file to provide this information for Linux.  Solaris mapfiles differ:
+
+	a) comments are not accepted
+	b) wildcards are not accepted, except for a special case of "_*".
+	c) each symbol listed in the map file must exist in the library
+
+	The Solaris limitations conflict with the development goal of providing
+	a small set of ".map" files as examples, which cover the most common
+	configurations.  Because that coverage is done by merging together
+	several builds, some symbols will be listed in the the ".map" files
+	that do not happen to be present in one configuration or another.
+
+	The sample ".map" (and ".sym") files are generated using a set of
+	scripts which build several configurations for each release version,
+	checking to see which of the "_nc_" symbols can be made local.  In
+	addition to the ncurses libraries and programs, the symbols used
+	by the "tack" program before version 1.08 are made global.
+
+	These sample ".map" files will not cover all possible combinations.
+	In some cases, e.g., when using the --with-weak-symbols option, you
+	may prefer to use a different ".map" file by setting this option's
+	value.
+
+    --with-wrap-prefix=XXX
+	When using the --enable-reentrant option, ncurses redefines variables
+	that would be global in curses, e.g., LINES, as a macro that calls a
+	"wrapping" function which fetches the data from the current SCREEN
+	structure.  Normally that function is named by prepending "_nc_" to the
+	variable's name.  The function is technically private (since portable
+	applications would not refer directly to it).  But according to one
+	line of reasoning, it is not the same type of "private" as functions
+	which applications should not call even via a macro.  This configure
+	option lets you choose the prefix for these wrapped variables.
+
+    --with-x11-rgb=FILE
+	Provide a pathname for the X11 rgb file, used by the picsmap program.
+	This overrides a configure check which usually works, but is needed
+	due to the lack of standardization for X11's files.
+
+    --with-xterm-kbs=XXX
+	Configure xterm's terminfo entries to use either BS (^H, i.e., ASCII
+	backspace) or DEL (^?, or 127).  XXX can be BS (or bs, 8) or DEL
+	(or del, 127).
+
+	During installation, the makefile and scripts modifies the "xterm+kbs"
+	terminfo entry to use this setting.
+
+    --without-ada
+	Suppress the configure script's check for Ada95, do not build the
+	Ada95 binding and related demo.
+
+    --without-curses-h
+	Don't install the ncurses header with the name "curses.h".  Rather,
+	install as "ncurses.h" and modify the installed headers and manpages
+	accordingly.
+
+	Likewise, do not install an alias "curses" for the ncurses manpage.
+
+    --without-cxx
+	XSI curses declares "bool" as part of the interface.  C++ also declares
+	"bool".  Neither specifies the size and type of booleans, but both
+	insist on the same name.  We chose to accommodate this by making the
+	configure script check for the size and type (e.g., unsigned or signed)
+	that your C++ compiler uses for booleans.  If you do not wish to use
+	ncurses with C++, use this option to tell the configure script to not
+	adjust ncurses bool to match C++.
+
+    --without-cxx-binding
+	Suppress the configure script's check for C++, do not build the
+	C++ binding and related demo.
+
+    --without-develop
+	Disable development options.  This does not include those that change
+	the interface, such as --enable-widec.
+
+    --without-dlsym
+	Do not use dlsym() to load GPM dynamically.
+
+    --without-manpages
+	Tell the configure script to suppress the install of ncurses' manpages.
+
+    --without-progs
+	Tell the configure script to suppress the build of ncurses' application
+	programs (e.g., tic).  The test applications will still be built if you
+	type "make", though not if you simply do "make install".
+
+    --without-tack
+	Suppress build/install with tack program, if it happens to be
+	in the same build-tree (tack was moved out of the ncurses source-tree
+	in 20070203).
+
+    --without-tests
+	Tell the configure script to suppress the build of ncurses' test
+	programs.
+
+    --without-xterm-new
+	Tell the configure script to use "xterm-old" for the entry used in
+	the terminfo database.  This will work with variations such as
+	X11R5 and X11R6 xterm.
+
+
+COMPATIBILITY WITH OLDER RELEASES:
+---------------------------------
+
+    Because ncurses implements X/Open Curses, its interface is fairly stable.
+    That does not mean the interface does not change.  Changes are made to the
+    documented interfaces when we find differences between ncurses and X/Open
+    or implementations which largely correspond to X/Open (such as Solaris).
+    We add extensions to those interfaces to solve problems not addressed by
+    the original curses design, but those must not conflict with the X/Open
+    documentation.
+
+    Here are some of the major interface changes, and related problems which
+    you may encounter when building a system with different versions of
+    ncurses:
+
+    6.4 (Dec 31, 2022)
+	Interface changes:
+
+	+ none
+
+	Added extensions:
+
+	+ none
+
+	Added internal functions (other than "_sp" variants):
+
+	+ add _nc_free_termtype1 and _nc_free_tparm, for memory-leaks
+
+	Removed internal functions:
+
+	+ none
+
+	Modified internal functions:
+
+	+ none
+
+    6.3 (Oct 21, 2021)
+	Interface changes:
+
+	+ the definition of TERMTYPE2 is now internal, not visible in the ABI,
+	  like the enclosing TERMINAL which was previously made opaque.  This
+	  was done to provide SCREEN-specific "static" variables in terminfo.
+
+	Added extensions:
+
+	+ add sp-funcs for erasewchar, killwchar.
+
+	Added internal functions (other than "_sp" variants):
+
+	+ _nc_safe_fopen and _nc_safe_open3 limit privileges if possible when
+	  opening a file; otherwise disallow access for updating files.
+
+	+ _nc_tiparm is a variant of tiparm which is used when all of the
+	  parameters are known to be numbers rather than possibly strings.
+
+	+ _nc_reset_tparm improves tic's checks by resetting the terminfo
+	  "static variables" before calling functions which may update them.
+
+	Removed internal functions:
+
+	+ none
+
+	Modified internal functions:
+
+	+ _nc_trace_ttymode passes pointer to const data
+
+	+ _nc_tparm_analyze passes pointer to int*, not int[]
+
+    6.2 (Feb 12, 2020)
+	Interface changes:
+
+	+ the terminal database must be compiled with ncurses 6.2 tic;
+	  older versions of tic/infocmp will not work.  Aside from that,
+	  the compiled database will work with older applications.
+
+	+ "*.pc" and "ncurses*-config" files give the same information.
+
+	+ vwprintw and vwscanw are deprecated.
+
+	Added extensions:
+
+	+ These make it simpler to substitute a debug-configuration of the
+	  library for non-debug:
+		curses_trace
+		exit_curses
+		exit_terminfo
+
+	Added internal functions (other than "_sp" variants):
+
+	+ These provide fast-lookup of common user-defined capabilities:
+		_nc_find_user_entry
+		_nc_get_userdefs_table
+		_nc_get_hash_user
+
+	+ This is added to work around compiler-warnings:
+		_nc_fmt_funcptr
+
+	Removed internal functions:
+
+	+ _nc_import_termtype
+
+	Modified internal functions:
+
+	+ _nc_reserve_pairs no longer returns a value
+
+    6.1 (Jan 27, 2018)
+	Interface changes:
+
+	+ X/Open Curses specifies a "reserved" void* parameter in several
+	  functions, saying that it must be NULL.  In this release, if the
+	  parameter is non-NULL, it is interpreted as a point to an integer
+	  containing a color pair.  In previous releases, a non-NULL parameter
+	  caused an error return.  Portable applications are unaffected.  Here
+	  are the functions which have been extended:
+		attr_get
+		attr_off
+		attr_on
+		attr_set
+		chgat
+		color_set
+		mvchgat
+		mvwchgat
+		slk_attr_off
+		slk_attr_on
+		slk_attr_set
+		wattr_get
+		wattr_on
+		wattr_off
+		wattr_set
+		wchgat
+		wcolor_set
+
+	+ the TERMINAL structure declared in <term.h> has been made opaque,
+	  and its size increased to handle the increased size of color pair
+	  and color value, as well as other numeric capabilities.
+
+	  A few applications required change, e.g., to use def_prog_mode;
+	  only one application (tack) is known to have a valid reason for
+	  accessing these internal details, and that was addressed by the
+	  release of tack 1.08 in 2017.  Internal functions marked as used
+	  by tack will be deprecated in future releases.
+
+	Added extensions:
+
+	+ Several new functions were added to manipulate extended color pairs
+	  and color values.  These include:
+		alloc_pair
+		extended_color_content
+		extended_pair_content
+		extended_slk_color
+		find_pair
+		free_pair
+		init_extended_color
+		init_extended_pair
+		reset_color_pairs
+
+	  as well as corresponding sp-functions.
+
+	+ A new terminfo capability "RGB" tells the ncurses library that the
+	  color values are red/green/blue, to eliminate the need for palettes
+	  in that special case for the color_content function.
+
+	Added internal functions (other than "_sp" variants):
+		_nc_copy_termtype2
+		_nc_export_termtype2
+		_nc_fallback2
+		_nc_find_prescr
+		_nc_forget_prescr
+		_nc_free_termtype2
+		_nc_read_entry2
+		_nc_write_object
+
+	Removed internal functions:
+		_nc_check_termtype
+		_nc_resolve_uses
+
+	Modified internal functions:
+
+	+ symbols are used by tic/infocmp/toe:
+		_nc_align_termtype - change parameters to TERMTYPE2*
+		_nc_check_termtype2 - change parameter to TERMTYPE2*
+		_nc_read_file_entry - change parameter to TERMTYPE2*
+		_nc_read_termtype - change parameter to TERMTYPE2*
+		_nc_trim_sgr0 - change parameter to TERMTYPE2*
+		_nc_write_entry - change parameter to TERMTYPE2*
+
+	+ symbols used only within the library:
+		_nc_fallback - change return type to TERMTYPE2*
+		_nc_init_termtype - change parameter to TERMTYPE2*
+
+    6.0 (Aug 08, 2015)
+	Interface changes:
+
+	+ The 6.0 ABI modifies the defaults for these configure options:
+	   --enable-const
+	   --enable-ext-colors
+	   --enable-ext-mouse
+	   --enable-ext-putwin
+	   --enable-interop
+	   --enable-lp64
+	   --enable-sp-funcs
+	   --with-chtype=uint32_t
+	   --with-mmask_t=uint32_t
+	   --with-tparm-arg=intptr_t
+
+	+ ncurses supports symbol versioning.  If you use this feature, about
+	  half of the "_nc_" private symbols are changed to local symbols.
+
+	+ a few applications may need to explicitly flush the standard output
+	  when switching between printf's and (curses) printw.
+
+	Added extensions:
+
+	+ use_tioctl is an improvement over use_env
+
+	+ added wgetdelay to support the NCURSES_OPAQUE feature.
+
+	Added internal functions (other than "_sp" variants):
+		_nc_init_termtype
+		_nc_mvcur
+		_nc_putchar
+		_nc_setenv_num
+		_nc_trace_mmask_t
+
+	Removed internal functions:
+		none
+
+	Modified internal functions:
+		_nc_do_color - change parameters from short/bool to int
+		_nc_keypad - change parameter from bool to int
+		_nc_setupscreen - change parameter from bool to int
+		_nc_signal_handler - change parameter from bool to int
+
+    5.9 (Apr 04, 2011)
+    5.8 (Feb 26, 2011)
+	Interface changes:
+
+	+ add an alternate library configuration, i.e., "terminal driver" to
+	  support port to Windows, built with MinGW.  There are two drivers
+	  (terminfo and Windows console).  The terminfo driver works on other
+	  platforms.
+
+	+ add a new set of functions which accept a SCREEN* parameter, in
+	  contrast with the original set which use the global value "sp".
+	  By default, these names end with "_sp", and are otherwise
+	  functionally identical with the originals.
+
+	  In addition to the "_sp" functions, there are a few new functions
+	  associated with this feature:  ceiling_panel, ground_panel,
+	  new_prescr.
+
+	  If the library is not built with the sp-funcs extension, there
+	  are no related interface changes.
+
+	+ add tiparm function based on review of X/Open Curses Issue 7.
+
+	+ change internal _nc_has_mouse function to public has_mouse function
+
+	Added extensions:
+
+	+ add a few more functions to support the NCURSES_OPAQUE feature:
+	  get_escdelay, is_pad, is_subwin
+
+	Added internal functions (other than "_sp" variants):
+		_nc_curscr_of
+		_nc_format_slks
+		_nc_get_alias_table
+		_nc_get_hash_info
+		_nc_insert_wch
+		_nc_newscr_of
+		_nc_outc_wrapper
+		_nc_retrace_char
+		_nc_retrace_int_attr_t
+		_nc_retrace_mmask_t
+		_nc_setup_tinfo
+		_nc_stdscr_of
+		_nc_tinfo_cmdch
+
+	Removed internal functions:
+		_nc_makenew (some configurations replace by _nc_makenew_sp)
+
+	Modified internal functions:
+		_nc_UpdateAttrs
+		_nc_get_hash_table
+		_nc_has_mouse
+		_nc_insert_ch
+		_nc_wgetch
+
+    5.7 (November 2, 2008)
+	Interface changes:
+
+	+ generate linkable stubs for some macros:
+		getattrs
+
+	+ Add new library configuration for tic-library (the non-curses portion
+	  of the ncurses library used for the tic program as well as some
+	  others such as tack.  There is no API change, but makefiles would be
+	  changed to use the tic-library built separately.
+
+	  tack, distributed separately from ncurses, uses some of the internal
+	  _nc_XXX functions, which are declared in the tic.h header file.
+
+	  The reason for providing this separate library is that none of the
+	  functions in it are suitable for threaded applications.
+
+	+ Add new library configuration (ncursest, ncurseswt) which provides
+	  rudimentary support for POSIX threads.  This introduces opaque
+	  access functions to the WINDOW structure and adds a parameter to
+	  several internal functions.
+
+	+ move most internal variables (except tic-library) into data blocks
+	  _nc_globals and _nc_prescreen to simplify analysis.  Those were
+	  globally accessible, but since they were not part of the documented
+	  API, there is no ABI change.
+
+	+ changed static tables of strings to be indices into long strings, to
+	  improve startup performance.  This changes parameter lists for some
+	  of the internal functions.
+
+	Added extensions:
+
+	+ add NCURSES_OPAQUE definition in curses.h to control whether internal
+	  details of the WINDOW structure are visible to an application.  This
+	  is always defined when the threaded library is built, and is optional
+	  otherwise.  New functions for this:  is_cleared, is_idcok, is_idlok,
+	  is_immedok, is_keypad, is_leaveok, is_nodelay, is_notimeout,
+	  is_scrollok, is_syncok, wgetparent and wgetscrreg.
+
+	+ the threaded library (ncursest) also disallows direct updating of
+	  global curses-level variables, providing functions (via macros) for
+	  obtaining their value.  A few of those variables can be modified by
+	  the application, using new functions:  set_escdelay, set_tabsize
+
+	+ added functions use_window() and use_screen() which wrap a mutex
+	  (if threading is configured) around a call to a user-supplied
+	  function.
+
+	Added internal functions:
+		_nc_get_alias_table
+		_nc_get_screensize
+		_nc_keyname
+		_nc_screen_of
+		_nc_set_no_padding
+		_nc_tracechar
+		_nc_tracemouse
+		_nc_unctrl
+		_nc_ungetch
+
+		These are used for leak-testing, and are stubs for
+		ABI compatibility when ncurses is not configured for that
+		using the --disable-leaks configure script option:
+
+		_nc_free_and_exit
+		_nc_leaks_tinfo
+
+	Removed internal functions:
+		none
+
+	Modified internal functions:
+		_nc_fifo_dump
+		_nc_find_entry
+		_nc_handle_sigwinch
+		_nc_init_keytry
+		_nc_keypad
+		_nc_locale_breaks_acs
+		_nc_timed_wait
+		_nc_update_screensize
+
+		Use new typedef TRIES to replace "struct tries":
+
+		_nc_add_to_try
+		_nc_expand_try
+		_nc_remove_key
+		_nc_remove_string
+		_nc_trace_tries
+
+    5.6 (December 17, 2006)
+	Interface changes:
+
+	+ generate linkable stubs for some macros:
+
+	  getbegx, getbegy, getcurx, getcury, getmaxx, getmaxy, getparx,
+	  getpary, getpary,
+
+	  and (for libncursesw)
+
+	  wgetbkgrnd
+
+	Added extensions:
+		nofilter()
+		use_legacy_coding()
+
+	Added internal functions:
+		_nc_first_db
+		_nc_get_source
+		_nc_handle_sigwinch
+		_nc_is_abs_path
+		_nc_is_dir_path
+		_nc_is_file_path
+		_nc_keep_tic_dir
+		_nc_keep_tic_dir
+		_nc_last_db
+		_nc_next_db
+		_nc_read_termtype
+		_nc_tic_dir
+
+		Also (if using the hashed database configuration):
+
+		_nc_db_close
+		_nc_db_first
+		_nc_db_get
+		_nc_db_have_data
+		_nc_db_have_index
+		_nc_db_next
+		_nc_db_open
+		_nc_db_put
+
+		otherwise
+
+		_nc_hashed_db
+
+	Removed internal functions:
+		none
+
+	Modified internal functions:
+		_nc_add_to_try
+		_nc_do_color
+		_nc_expand_try
+		_nc_remove_key
+		_nc_setupscreen
+
+    5.5 (October 10, 2005)
+	Interface changes:
+
+	+ terminfo installs "xterm-new" as "xterm" entry rather than
+	  "xterm-old" (aka xterm-r6).
+
+	+ terminfo data is installed using the tic -x option (few systems
+	  still use ncurses 4.2).
+
+	+ modify C++ binding to work with newer C++ compilers by providing
+	  initializers and using modern casts.  Old-style header names are
+	  still used in this release to allow compiling with not-so-old
+	  compilers.
+
+	+ form and menu libraries now work with wide-character data.
+	  Applications which bypassed the form library and manipulated the
+	  FIELD.buf data directly will not work properly with libformw, since
+	  that no longer points to an array of char.  The set_field_buffer()
+	  and field_buffer() functions translate to/from the actual field
+	  data.
+
+	+ change SP->_current_attr to a pointer, adjust ifdef's to ensure that
+	  libtinfo.so and libtinfow.so have the same ABI.  The reason for this
+	  is that the corresponding data which belongs to the upper-level
+	  ncurses library has a different size in each model.
+
+	+ winnstr() now returns multibyte character strings for the
+	  wide-character configuration.
+
+	+ assume_default_colors() no longer requires that use_default_colors()
+	  be called first.
+
+	+ data_ahead() now works with wide-characters.
+
+	+ slk_set() and slk_wset() now accept and store multibyte or
+	  multicolumn characters.
+
+	+ start_color() now returns OK if colors have already been started.
+	  start_color() also returns ERR if it cannot allocate memory.
+
+	+ pair_content() now returns -1 for consistency with init_pair() if it
+	  corresponds to the default-color.
+
+	+ unctrl() now returns null if its parameter does not correspond
+	  to an unsigned char.
+
+	Added extensions:
+		Experimental mouse version 2 supports wheel mice with buttons
+		4 and 5.  This requires ABI 6 because it modifies the encoding
+		of mouse events.
+
+		Experimental extended colors allows encoding of 256 foreground
+		and background colors, e.g., with the xterm-256color or
+		xterm-88color terminfo entries.  This requires ABI 6 because
+		it changes the size of cchar_t.
+
+	Added internal functions:
+		_nc_check_termtype2
+		_nc_resolve_uses2
+		_nc_retrace_cptr
+		_nc_retrace_cvoid_ptr
+		_nc_retrace_void_ptr
+		_nc_setup_term
+
+	Removed internal functions:
+		none
+
+	Modified internal functions:
+		_nc_insert_ch
+		_nc_save_str
+		_nc_trans_string
+
+    5.4 (February 8, 2004)
+	Interface changes:
+
+	+ add the remaining functions for X/Open curses wide-character support.
+	  These are only available if the library is configured using the
+	  --enable-widec option.
+		pecho_wchar()
+		slk_wset()
+
+	+ write getyx() and related 2-return macros in terms of getcury(),
+	  getcurx(), etc.
+
+	+ simplify ifdef for bool declaration in curses.h
+
+	+ modify ifdef's in curses.h that disabled use of __attribute__() for
+	  g++, since recent versions implement the cases which ncurses uses.
+
+	+ change some interfaces to use const:
+		define_key()
+		mvprintw()
+		mvwprintw()
+		printw()
+		vw_printw()
+		winsnstr()
+		wprintw()
+
+	Added extensions:
+		key_defined()
+
+	Added internal functions:
+		_nc_get_locale()
+		_nc_insert_ch()
+		_nc_is_charable()	wide
+		_nc_locale_breaks_acs()
+		_nc_pathlast()
+		_nc_to_char()		wide
+		_nc_to_widechar()	wide
+		_nc_tparm_analyze()
+		_nc_trace_bufcat()	debug
+		_nc_unicode_locale()
+
+	Removed internal functions:
+		_nc_outstr()
+		_nc_sigaction()
+
+	Modified internal functions:
+		_nc_remove_string()
+		_nc_retrace_chtype()
+
+    5.3 (October 12, 2002)
+	Interface changes:
+
+	+ change type for bool used in headers to NCURSES_BOOL, which usually
+	  is the same as the compiler's definition for 'bool'.
+
+	+ add all but two functions for X/Open curses wide-character support.
+	  These are only available if the library is configured using the
+	  --enable-widec option.  Missing functions are
+		pecho_wchar()
+		slk_wset()
+
+	+ add environment variable $NCURSES_ASSUMED_COLORS to modify the
+	  assume_default_colors() extension.
+
+	Added extensions:
+		is_term_resized()
+		resize_term()
+
+	Added internal functions:
+		_nc_altcharset_name()	debug
+		_nc_reset_colors()
+		_nc_retrace_bool()	debug
+		_nc_retrace_unsigned()	debug
+		_nc_rootname()
+		_nc_trace_ttymode()	debug
+		_nc_varargs()		debug
+		_nc_visbufn()		debug
+		_nc_wgetch()
+
+	Removed internal functions:
+		_nc_background()
+
+	Modified internal functions:
+		_nc_freeall()		debug
+
+    5.2 (October 21, 2000)
+	Interface changes:
+
+	+ revert termcap ospeed variable to 'short' (see discussion of the
+	  --with-ospeed configure option).
+
+    5.1 (July 8, 2000)
+	Interface changes:
+
+	+ made the extended terminal capabilities
+	  (configure --enable-tcap-names) a standard feature.  This should
+	  be transparent to applications that do not require it.
+
+	+ removed the trace() function and related trace support from the
+	  production library.
+
+	+ modified curses.h.in, undef'ing some symbols to avoid conflict
+	  with C++ STL.
+
+	Added extensions:  assume_default_colors().
+
+    5.0 (October 23, 1999)
+	Interface changes:
+
+	+ implemented the wcolor_set() and slk_color() functions.
+
+	+ move macro winch to a function, to hide details of struct ldat
+
+	+ corrected prototypes for slk_* functions, using chtype rather than
+	  attr_t.
+
+	+ the slk_attr_{set,off,on} functions need an additional void*
+	  parameter according to XSI.
+
+	+ modified several prototypes to correspond with 1997 version of X/Open
+	  Curses:  [w]attr_get(), [w]attr_set(), border_set() have different
+	  parameters.  Some functions were renamed or misspelled:
+	  erase_wchar(), in_wchntr(), mvin_wchntr().  Some developers have used
+	  attr_get().
+
+	Added extensions:  keybound(), curses_version().
+
+	Terminfo database changes:
+
+	+ change translation for termcap 'rs' to terminfo 'rs2', which is
+	  the documented equivalent, rather than 'rs1'.
+
+	The problems are subtler in recent releases.
+
+	a) This release provides users with the ability to define their own
+	   terminal capability extensions, like termcap.  To accomplish this,
+	   we redesigned the TERMTYPE struct (in term.h).  Very few
+	   applications use this struct.  They must be recompiled to work with
+	   the 5.0 library.
+
+	a) If you use the extended terminfo names (i.e., you used configure
+	   --enable-tcap-names), the resulting terminfo database can have some
+	   entries which are not readable by older versions of ncurses.  This
+	   is a bug in the older versions:
+
+	   + the terminfo database stores booleans, numbers and strings in
+	     arrays.  The capabilities that are listed in the arrays are
+	     specified by X/Open.  ncurses recognizes a number of obsolete and
+	     extended names which are stored past the end of the specified
+	     entries.
+
+	   + a change to read_entry.c in 951001 made the library do an lseek()
+	     call incorrectly skipping data which is already read from the
+	     string array.  This happens when the number of strings in the
+	     terminfo data file is greater than STRCOUNT, the number of
+	     specified and obsolete or extended strings.
+
+	   + as part of alignment with the X/Open final specification, in the
+	     990109 patch we added two new terminfo capabilities:
+	     set_a_attributes and set_pglen_inch).  This makes the indices for
+	     the obsolete and extended capabilities shift up by 2.
+
+	   + the last two capabilities in the obsolete/extended list are memu
+	     and meml, which are found in most terminfo descriptions for xterm.
+
+	     When trying to read this terminfo entry, the spurious lseek()
+	     causes the library to attempt to read the final portion of the
+	     terminfo data (the text of the string capabilities) 4 characters
+	     past its starting point, and reads 4 characters too few.  The
+	     library rejects the data, and applications are unable to
+	     initialize that terminal type.
+
+	   FIX: remove memu and meml from the xterm description.  They are
+	   obsolete, not used by ncurses.  (It appears that the feature was
+	   added to xterm to make it more like hpterm).
+
+	   This is not a problem if you do not use the -x option of tic to
+	   create a terminfo database with extended names.  Note that the
+	   user-defined terminal capabilities are not affected by this bug,
+	   since they are stored in a table after the older terminfo data ends,
+	   and are invisible to the older libraries.
+
+	c) Some developers did not wish to use the C++ binding, and used the
+	   configure --without-cxx option.  This causes problems if someone
+	   uses the ncurses library from C++ because that configure test
+	   determines the type for C++'s bool and makes ncurses match it, since
+	   both C++ and curses are specified to declare bool.  Calling ncurses
+	   functions with the incorrect type for bool will cause execution
+	   errors.  In 5.0 we added a configure option "--without-cxx-binding"
+	   which controls whether the binding itself is built and installed.
+
+    4.2 (March 2, 1998)
+	Interface changes:
+
+	+ correct prototype for termattrs() as per XPG4 version 2.
+
+	+ add placeholder prototypes for color_set(), erasewchar(),
+	  term_attrs(), wcolor_set() as per XPG4 version 2.
+
+	+ add macros getcur[xy] getbeg[xy] getpar[xy], which are defined in
+	  SVr4 headers.
+
+	New extensions: keyok() and define_key().
+
+	Terminfo database changes:
+
+	+ corrected definition in curses.h for ACS_LANTERN, which was 'I'
+	  rather than 'i'.
+
+    4.1 (May 15, 1997)
+
+	We added these extensions:  use_default_colors().  Also added
+	configure option --enable-const, to support the use of const where
+	X/Open should have, but did not, specify.
+
+	The terminfo database content changed the representation of color for
+	most entries that use ANSI colors.  SVr4 curses treats the setaf/setab
+	and setf/setb capabilities differently, interchanging the red/blue
+	colors in the latter.
+
+    4.0 (December 24, 1996)
+
+	We bumped to version 4.0 because the newly released Linux dynamic
+	loader (ld.so.1.8.5) did not load shared libraries whose ABI and REL
+	versions were inconsistent.  At that point, ncurses ABI was 3.4 and the
+	REL was 1.9.9g, so we made them consistent.
+
+    1.9.9g (December 1, 1996)
+
+	This fixed most of the problems with 1.9.9e, and made these interface
+	changes:
+
+	+ remove tparam(), which had been provided for compatibility with
+	  some termcap.  tparm() is standard, and does not conflict with
+	  application's fallback for missing tparam().
+
+	+ turn off hardware echo in initscr().  This changes the sense of the
+	  echo() function, which was initialized to echoing rather than
+	  nonechoing (the latter is specified).  There were several other
+	  corrections to the terminal I/O settings which cause applications to
+	  behave differently.
+
+	+ implemented several functions (such as attr_on()) which were
+	  available only as macros.
+
+	+ corrected several typos in curses.h.in (i.e., the mvXXXX macros).
+
+	+ corrected prototypes for delay_output(),
+	  has_color, immedok() and idcok().
+
+	+ corrected misspelled getbkgd().  Some applications used the
+	  misspelled name.
+
+	+ added _yoffset to WINDOW.  The size of WINDOW does not impact
+	  applications, since they use only pointers to WINDOW structs.
+
+	These changes were made to the terminfo database:
+
+	+ removed boolean 'getm' which was available as an extended name.
+
+	We added these extensions: wresize(), resizeterm(), has_key() and
+	mcprint().
+
+    1.9.9e (March 24, 1996)
+
+	not recommended (a last-minute/untested change left the forms and
+	menus libraries unusable since they do not repaint the screen).
+	Foreground/background colors are combined incorrectly, working properly
+	only on a black background.  When this was released, the X/Open
+	specification was available only in draft form.
+
+	Some applications (such as lxdialog) were "fixed" to work with the
+	incorrect color scheme.
+
+
+FOR SYSTEM INTEGRATORS:
+----------------------
+
+    Configuration and Installation:
+
+	On platforms where ncurses is assumed to be installed in /usr/lib,
+	the configure script uses "/usr" as a default.  These include any
+	that use the Linux kernel, as well as these special cases:
+
+		FreeBSD, NetBSD, OpenBSD, Cygwin, MinGW
+
+	For other platforms, the default is "/usr/local".  See the discussion
+	of the "--disable-overwrite" option.
+
+	The location of the terminfo is set indirectly by the "--datadir"
+	configure option, e.g., /usr/share/terminfo, given a datadir of
+	/usr/share.  You may want to override this if you are installing
+	ncurses libraries in nonstandard locations, but wish to share the
+	terminfo database.
+
+	Normally the ncurses library is configured in a pure-terminfo mode;
+	that is, with the --disable-termcap option.  This makes the ncurses
+	library smaller and faster.  The ncurses library includes a termcap
+	emulation that queries the terminfo database, so even applications that
+	use raw termcap to query terminal characteristics will win (providing
+	you recompile and relink them!).
+
+	If you must configure with termcap fallback enabled, you may also wish
+	to use the --enable-getcap option.  This speeds up termcap-based
+	startups, at the expense of not allowing personal termcap entries to
+	reference the terminfo tree.  See comments in
+	ncurses/tinfo/read_termcap.c for further details.
+
+	Note that if you have $TERMCAP set, ncurses will use that value
+	to locate termcap data.  In particular, running from xterm will
+	set $TERMCAP to the contents of the xterm's termcap entry.
+	If ncurses sees that, it will not examine /etc/termcap.
+
+    Keyboard Mapping:
+
+	The terminfo file assumes that Shift-Tab generates \E[Z (the ECMA-48
+	reverse-tabulation sequence) rather than ^I.  Here are the loadkeys -d
+	mappings that will set this up:
+
+		keycode	 15 = Tab	      Tab
+			alt     keycode  15 = Meta_Tab
+			shift	keycode  15 = F26
+		string F26 ="\033[Z"
+
+    Naming the Console Terminal
+
+	In various systems there has been a practice of designating the system
+	console driver type as `console'.  Please do not do this!  It
+	complicates peoples' lives, because it can mean that several different
+	terminfo entries from different operating systems all logically want to
+	be called `console'.
+
+	Please pick a name unique to your console driver and set that up
+	in the /etc/inittab table or local equivalent.  Send the entry to the
+	terminfo maintainer (listed in the misc/terminfo file) to be included
+	in the terminfo file, if it is not already there.  See the
+	term(7) manual page included with this distribution for more on
+	conventions for choosing type names.
+
+	Here are some recommended primary console names:
+
+		linux	-- Linux console driver
+		freebsd	-- FreeBSD
+		netbsd	-- NetBSD
+		bsdos	-- BSD/OS
+
+	If you are responsible for integrating ncurses for one of these
+	distributions, please either use the recommended name or get back
+	to us explaining why you don't want to, so we can work out nomenclature
+	that will make users' lives easier rather than harder.
+
+
+MODERN XTERM VERSIONS:
+---------------------
+
+	The terminfo database file included with this distribution assumes you
+	are running a modern xterm based on XFree86 (i.e., xterm-new).  The
+	earlier X11R6 entry (xterm-r6) and X11R5 entry (xterm-r5) is provided
+	as well.  See the --without-xterm-new configure script option if you
+	are unable to update your system.
+
+
+CONFIGURING FALLBACK ENTRIES:
+----------------------------
+
+	In order to support operation of ncurses programs before the terminfo
+	tree is accessible (that is, in single-user mode or at OS installation
+	time) the ncurses library can be compiled to include an array of
+	pre-fetched fallback entries.
+
+	NOTE: This must be done on a machine which has ncurses' infocmp and
+	terminfo database installed (as well as ncurses' tic and infocmp
+	programs).  That is because the fallback sources are generated and
+	compiled into the library before the build-tree's copy of infocmp is
+	available.
+
+	These entries are checked by setupterm() only when the conventional
+	fetches from the terminfo tree and the termcap fallback (if configured)
+	have been tried and failed.  Thus, the presence of a fallback will not
+	shadow modifications to the on-disk entry for the same type, when that
+	entry is accessible.
+
+	By default, there are no entries on the fallback list.  After you have
+	built the ncurses suite for the first time, you can change the list
+	(the process needs infocmp(1)).  To do so, use the script
+	ncurses/tinfo/MKfallback.sh.  The configure script option
+	--with-fallbacks does this (it accepts a comma-separated list of the
+	names you wish, and does not require a rebuild).
+
+	If you wanted (say) to have linux, vt100, and xterm fallbacks, you
+	might use the commands
+
+		cd ncurses;
+		tinfo/MKfallback.sh \
+			$TERMINFO \
+			../misc/terminfo.src \
+			`which tic` \
+			`which infocmp` \
+			linux vt100 xterm >fallback.c
+
+	The first four parameters of the script are normally supplied by
+	the configured makefiles via the "--with-fallbacks" option.  They
+	are
+
+		1) the location of the terminfo database
+		2) the source for the terminfo entries
+		3) the location of the tic program, used to create a terminfo
+		   database.
+		4) the location of the infocmp program, used to print a terminfo
+		   description.
+
+	Then just rebuild and reinstall the library as you would normally.
+	You can restore the default empty fallback list with
+
+		tinfo/MKfallback.sh \
+			$TERMINFO \
+			../misc/terminfo.src \
+			`which tic` \
+			`which infocmp` \
+			>fallback.c
+
+	The overhead for an empty fallback list is one trivial stub function.
+	Any non-empty fallback list is const'd and therefore lives in shareable
+	text space.  You can look at the comment trailing each initializer in
+	the generated ncurses/fallback.c file to see the core cost of the
+	fallbacks.  A good rule of thumb for modern vt100-like entries is that
+	each one will cost about 2.5K of text space.
+
+
+BSD CONVERSION NOTES:
+--------------------
+
+	If you need to support really ancient BSD programs, you probably
+	want to configure with the --enable-bsdpad option.  What this does
+	is enable code in tputs() that recognizes a numeric prefix on a
+	capability as a request for that much trailing padding in milliseconds.
+	There are old BSD programs that do things like tputs("50").
+
+	(If you are distributing ncurses as a support-library component of
+	an application you probably want to put the remainder of this section
+	in the package README file.)
+
+	The following note applies only if you have configured ncurses with
+	--enable-termcap.
+
+------------------------------- CUT HERE --------------------------------
+
+If you are installing this application privately (either because you
+have no root access or want to experiment with it before doing a root
+installation), there are a couple of details you need to be aware of.
+They have to do with the ncurses library, which uses terminfo rather
+than termcap for describing terminal characteristics.
+
+Though the ncurses library is terminfo-based, it can interpret your
+TERMCAP variable (if present), any local termcap files you reference
+through it, and the system termcap file.  However, to avoid slowing
+down your application startup, it does this only once per terminal type!
+
+The first time you load a given terminal type from your termcap
+database, the library initialization code will automatically write it
+in terminfo format to a subdirectory under $HOME/.terminfo.  After
+that, the initialization code will find it there and do a (much
+faster) terminfo fetch.
+
+Usually, all this means is that your home directory will silently grow
+an invisible .terminfo subdirectory which will get filled in with
+terminfo descriptions of terminal types as you invoke them.  If anyone
+ever installs a global terminfo tree on your system, this will quietly
+stop happening and your $HOME/.terminfo will become redundant.
+
+The objective of all this logic is to make converting from BSD termcap
+as painless as possible without slowing down your application (termcap
+compilation is expensive).
+
+If you don't have a TERMCAP variable or custom personal termcap file,
+you can skip the rest of this dissertation.
+
+If you *do* have a TERMCAP variable and/or a custom personal termcap file
+that defines a terminal type, that definition will stop being visible
+to this application after the first time you run it, because it will
+instead see the terminfo entry that it wrote to $HOME/terminfo the
+first time around.
+
+Subsequently, editing the TERMCAP variable or personal TERMCAP file
+will have no effect unless you explicitly remove the terminfo entry
+under $HOME/terminfo.  If you do that, the entry will be recompiled
+from your termcap resources the next time it is invoked.
+
+To avoid these complications, use infocmp(1) and tic(1) to edit the
+terminfo directory directly.
+
+------------------------------- CUT HERE --------------------------------
+
+USING GPM:
+---------
+	Ncurses 4.1 and up can be configured to use GPM (General Purpose Mouse)
+	which is used with Linux console.  Be aware that GPM is commonly
+	installed as a shared library which contains a wrapper for the curses
+	wgetch() function (libcurses.o).  Some integrators have simplified
+	linking applications by combining all or part of libcurses.so into the
+	libgpm.so file, producing symbol conflicts with ncurses (specifically
+	the wgetch function).  This was originally the BSD curses, but
+	generally whatever curses library exists on the system.
+
+	You may be able to work around this problem by linking as follows:
+
+		cc -o foo foo.o -lncurses -lgpm -lncurses
+
+	but the linker may not cooperate, producing mysterious errors.
+	See the FAQ, as well as the discussion under the --with-gpm option:
+
+	https://invisible-island.net/ncurses/ncurses.faq.html#using_gpm_lib
+
+
+BUILDING WITH A CROSS-COMPILER:
+------------------------------
+	Ncurses can be built with a cross-compiler.  Some parts must be built
+	with the host's compiler since they are used for building programs
+	(e.g., ncurses/make_hash and ncurses/make_keys) that generate tables
+	that are compiled into the ncurses library.  The essential thing to do
+	is set the BUILD_CC environment variable to your host's compiler, and
+	run the configure script configuring for the cross-compiler.
+
+	The configure options --with-build-cc, etc., are provided to make this
+	simpler.  Since make_hash and make_keys use only ANSI C features, it
+	is normally not necessary to provide the other options such as
+	--with-build-libs, but they are provided for completeness.
+
+	Note that all of the generated source-files which are part of ncurses
+	will be made if you use
+
+		make sources
+
+	This would be useful in porting to an environment which has little
+	support for the tools used to generate the sources, e.g., sed, awk and
+	Bourne-shell.
+
+	When ncurses has been successfully cross-compiled, you may want to use
+	"make install" (with a suitable target directory) to construct an
+	install tree.  Note that in this case (as with the --with-fallbacks
+	option), ncurses uses the development platform's tic to do the "make
+	install.data" portion.
+
+	The system's tic program is used to install the terminal database,
+	even for cross-compiles.  For best results, the tic program should be
+	from the most current version of ncurses.
+
+	NOTE:  the system's tic program may use a different terminfo database
+	format than the target system.  For instance, as described in term(5),
+	the conventional terminfo layout uses a directory hierarchy with one
+	letter names, while some platforms use two-letter names to work with
+	case-insensitive filesystems.  The configure script searches for a tic
+	program using the AC_CHECK_TOOL macro, which will prefer programs
+	using the canonical host prefix in their name.  You can use this fact
+	to provide a cross-compiler support utility tic, otherwise you can
+	override the configure script's choice using --with-tic-path
+

+#
+# Wrapper Makefile for ncurses library under OS/2.
+# Author:  Juan Jose Garcia Ripoll <worm@arrakis.es>.
+# Webpage: http://www.arrakis.es/~worm/
+################################################################################
+#
+# Notes (from I Zakharevich)
+# ~~~~~~~~~~~~~~~~~~~~~~~~~~
+# I could build the library with the following sequence of commands:
+#
+#   touch Makefile
+#   make -f Makefile.os2 config
+#   make -f Makefile.os2 CC=gcc HOSTCC=gcc CXX=gcc
+#
+# Ignoring the following errors:
+#   Invalid configuration `os2'...
+#   ... ac_maketemp="make": not found
+#   ... syntax error: `done' unexpected
+#   No rule to make target `lib/ncurses4.dll'
+#
+# You may need to run
+#
+#   rm make.defs
+#   make -f Makefile.os2 make.defs
+#
+# if the build of misc/panel.def fails.
+#
+# If you do not have perl, the configuration will fail.  Use autoconf to
+# generate the EMX-specific configure script (see README.emx), and run the
+# configure script to generate the makefiles.  Then, run
+#
+#   make -f Makefile.os2 make.dlls
+#
+# Notes (from J J G Ripoll)
+# ~~~~~~~~~~~~~~~~~~~~~~~~~
+# The `make.defs' rule creates the new '.def' files and outputs a diagnostic
+# about symbols that disappear from one release to the other, as well as
+# checks about the new '.def' consistency.  If there were no problems, the
+# maintainer is free to replace the `.ref' files with the newer ones using the
+# `save.defs' rule.  So, the only tough work is ensuring that the symbols that
+# disappear are not essential.
+#
+# I first thought about killing '_nc_*' symbols, but it seems that some of
+# them --_nc_panel_hook, _nc_ada*, etc-- are needed outside ncurses.dll.
+# However, the whole size of the export table will not be larger than 1k or
+# so.
+#
+# [installation]
+#
+# The way things are handled in misc/Makefile is not well suited for OS/2,
+# where only emx.src is needed.  Thus, I've written a few wrapper rules in
+# Makefile.os2 that handle installation/deinstallation.
+#
+# [distribution]
+#
+# There's also a new rule that configures and builds a sort of binary
+# distribution, much like the one I prepared for 1.9.9e.  It's `os2dist'.

+This is a log of changes that ncurses has gone through since Zeyd started
+working with Pavel Curtis' original work, pcurses, in 1992.
+
+Changes through 1.9.9e are recorded by Zeyd M Ben-Halim.
+Changes since 1.9.9e are recorded by Thomas E Dickey.
+
+Contributors include those who have provided patches (even small ones), as well
+as those who provide useful information (bug reports, analyses).  Changes with
+no cited author are the work of Thomas E Dickey (TD).
+
+A few contributors may be cited in this file by their initials.
+Each accounts for half of one percent or more of the changes since 1.9.9e.
+See the AUTHORS file for the corresponding full names.
+
+Changes through 1.9.9e did not credit all contributions;
+it is not possible to add this information.

+20221203
+	+ add -h usage and -V version options to the test-programs which use
+	  getopt.
+	+ use "command -v" rather than "type" in Ada95/gen/Makefile.in to fix
+	  a portability issue (patch by Nicolas Boulenguez).
+	+ update ncurses-howto, more documentation fixes along with corrections
+	  to example programs.
+
+20221126
+	+ fix an error in pathname of explain.txt (cf: 20200201).
+	+ fix an error in "@" command in test/ncurses.c F-menu (cf: 20190121).
+	+ improve formatting of ncurses-intro.html and hackguide.html
+	+ improve man/curs_clear.3x links to other pages
+
+20221119
+	+ use static libraries for AdaCurses test-package for Mageia, since no
+	  gprbuild package is available.
+	+ updated test packages for Debian.
+
+20221112
+	+ build-fixes for AdaCurses RPM test-package.
+
+20221105
+	+ regenerate configure scripts with autoconf 2.52.20221009
+	+ modify "--with-manpage-format" to support bzip2 and xz compression
+	  (prompted by discussion with Sam James).
+	+ modify make-tar.sh scripts to make timestamps more predictable.

+	+ improve curs_slk.3x discussion of extensions and portability (report
+	  by Bill Gray).
+
+20221023
+	+ change man_db.renames to template, to handle ncurses*-config script
+	  with the extra-suffix configure option.
+
+20221015
+	+ fix another memory-leak in tic.
+	+ update install-sh script from autoconf, to fix install problem for
+	  Ada95 with Arch; as noted in
+	  https://lists.gnu.org/archive/html/automake/2018-09/msg00005.html
+	  there are unaddressed issues.
+	+ update CF_XOPEN_SOURCE, adding GNU libc suffixes for abi64, abin32,
+	  x32 (report by Sven Joachim):
+	+ correct ifdef's for _nc_set_read_thread() (patch by Mikhail Korolev,
+	  cf: 20220813).
+
+20221008
+	+ correct a switch-statement case in configure script to allow for test
+	  builds with ABI=7.
+	+ modify misc/gen-pkgconfig.in to allow for the case where the library
+	  directory does not yet exist, since this is processed before doing an
+	  install (report by Michal Liszcz).
+
+20221001
+	+ modify configure/scripts to work around interference by GNU grep 3.8
+	  (report by Sam James).
+	+ update CF_XOPEN_SOURCE, adding variants "gnueabi" and "gnueabihf" to
+	  get _DEFAULT_SOURCE special case (report by Adam Sampson)
+
+20220924
+	+ modify configure macro CF_BUILD_CC to check if the build-compiler
+	  works, rather than that it is different from the cross-compiler, e.g.,
+	  to accommodate a compiler which can be used for either purpose with
+	  different flags (report by Mikhail Korolev).
+	+ fix another memory-leak in tic.
+	+ correct change for cppcheck in menu library (report/analysis by
+	  "tuxway", cf: 20220903).
+	+ update config.guess, config.sub
+
+20220917
+	+ reduce memory-leak in tic by separating allocations for struct entry
+	  from TERMTYPE2 (cf: 20220430).
+	+ improve interaction between tic -v option and NCURSES_TRACE, by
+	  processing the latter only when -v option does not set _nc_tracing.
+	+ modify curses_trace() to show the trace-mask as symbols, e.g.,
+	  TRACE_ORDINARY, DEBUG_LEVEL(3).
+
+20220910
+	+ amend verbose-option change to make this affect level 3, e.g., using
+	  "tic -cv3 terminfo".
+	+ work around musl's nonstandard use of feature test macros by adding
+	  a definition for NCURSES_WIDECHAR to the generated ".pc" and *-config
+	  files (report by Sam James).
+
+20220903
+	+ modify verbose-option of infocmp, tic, toe to enable debug-tracing
+	  if that is configured.
+
+20220827
+	+ modify configure scripts to use overlooked cases for LD and
+	  PKG_CONFIG variables (report by Alan Webb, Gentoo #866398).
+	+ modify nsterm to use xterm+alt1049 (report by Paul Handly) -TD
+	+ modify putty to use xterm+alt1049 -TD
+
+20220820
+	+ fix some cppcheck warnings, mostly style, in ncurses and c++
+	  libraries and progs directory.
+	+ add curses_trace to ifdef's for START_TRACE in test/test.priv.h
+	+ update config.guess
+
+20220813
+	+ modify delscreen to more effectively delete all windows on the given
+	  screen.
+	+ amend portability note for delwin in manual page.
+	+ adapt test/test_delwin.c from example by Bill Gray.
+	+ account for prescreen data if freeing leaks in pthread-configuration
+	+ split-out _nc_set_read_thread(), to reduce compiler warnings about
+	  pthread_self(), which may/may not be a weak symbol.
+	+ improve pthread-configuration for test/worm.c
+
+20220806
+	+ amend end_of_stream() to allow for input files without a final
+	  newline.
+	+ check for non-textfiles to tic.
+
+20220729
+	+ fixes to build with dietlibc:
+	  + add configure check for fpathconf (report by Georg Lehner).

+	  + correct order of checks in _nc_get_locale(), for systems lacking
+	    locale support.
+	  + add "#error" in a few places to flag unsupported configurations
+
+20180623
+	+ use _WIN32/_WIN64 in preference to __MINGW32__/__MINGW64__ symbols
+	  to simplify building with MSVC, since the former are defined in both
+	  compiler configurations (report by Ali Abdulkadir).
+	+ further improvements to configure-checks from work on dialog, i.e.,
+	  updated CF_ADD_INCDIR, CF_FIND_LINKAGE, CF_GCC_WARNINGS,

+20180609
+	+ modify generated ncurses*config and ncurses.pc, ncursesw.pc, etc.,
+	  to list helper libraries such as gpm for static linking (Debian

+	+ add RPM test-package "ncursest-examples".
+	+ modified RPM test-package to work with Mageia6.
+
+20180526
+	+ add note in curs_util.3x about unctrl.h
+	+ review/improve header files to ensure that those include necessary
+	  files except for the previously-documented cases (report by Isaac
+	  Pascual Monells).
+	+ improved test-package scripts, adapted from byacc 1.9 20180525.
+	+ fix some gcc8 warnings seen in Redhat package build, but
+	  work around bug in gcc8 compiler warnings in comp_parse.c
+

+20180505
+	+ add deprecation warnings for internal functions called by older
+	  versions of tack.
+	+ fix a special case in PutAttrChar() where a cell is marked as
+	  alternate-character set, but the terminal does not actually support
+	  the given graphic character.  This would happen in an older terminal
+	  such as vt52, which lacks most line-drawing capability.
+	+ use configure --with-config-suffix option to work around filename
+	  conflict with Debian packages versus test-packages.
+	+ update tracemunch to work with perl 5.26.2, which changed the rules
+	  for escaping regular expressions.
+
+20180428
+	+ document new form-extension O_EDGE_INSERT_STAY (report by Leon
+	  Winter).
+	+ correct error-returns listed in manual pages for a few form functions
+	  (report by Leon Winter).
+	+ add a check in form-library for null-pointer dereference:

+	  (patch by Leon Winter).
+
+20180414

+	  edge/boundary (patch by Leon Winter).
+	+ modify form library to avoid unnecessary update of cursor position in
+	  non-public fields (patch by Leon Winter).
+	+ remove unused _nc_import_termtype2() function.
+	+ also add/improve null-pointer checks in other places
+	+ add a null-pointer check in _nc_parse_entry to handle an error when
+	  a use-name is invalid syntax (report by Chung-Yi Lin).
+
+20180407
+	+ clarify in manual pages that vwprintw and vwscanw are obsolete,
+	  not part of X/Open Curses since 2007.
+	+ use "const" in some prototypes rather than NCURSES_CONST where X/Open
+	  Curses was updated to do this, e.g., wscanw, newterm, the terminfo
+	  interface.  Also use "const" for consistency in the termcap
+	  interface, which was withdrawn by X/Open Curses in Issue 5 (2007).
+	  As of Issue 7, X/Open Curses still lacks "const" for certain return
+	  values, e.g., keyname().
+
+20180331
+	+ improve terminfo write/read by modifying the fourth item of the
+	  extended header to denote the number of valid strings in the extended
+	  string table (prompted by a comment in unibilium's sources).
+
+20180324
+	+ amend Scaled256() macro in test/picsmap.c to cover the full range
+	  0..1000 (report by Roger Pau Monne).

+	+ fix a check in infotocap which may not have detected a problem when
+	  it should have.
+	+ add a check in tic for the case where setf/setb are given using
+	  different strings, but provide identical results to setaf/setab.
+	+ further improve fix for terminfo.5 (patch by Kir Kolyshkin).
+	+ reorder loop-limit checks in winsnstr() in case the string has no
+	  terminating null and only the number of characters is used (patch
+	  by Gyorgy Jeney).
+
+20180303
+	+ modify TurnOn/TurnOff macros in lib_vidattr.c and lib_vid_attr.c to
+	  avoid expansion of "CUR" in trace.
+	+ improve a few lintian warnings in test-packages.
+	+ modify lib_setup to avoid calling pthread_self() without first
+	  verifying that the address is valid, i.e., for weak symbols
+	  (report/patch by Werner Fink).
+	+ modify generated terminfo.5 to not use "expand" and related width
+	  on the last column of tables, making layout on wide terminals look
+	  better (adapted from patch by Kir Kolyshkin).
+	+ add a category to report_offsets, e.g., "w" for wide-character, "t"
+	  for threads to make the report more readable.  Reorganized the
+	  structures reported to make the categories more apparent.
+	+ simplify some ifdef's for extended-colors.
+	+ add NCURSES_GLOBALS and NCURSES_PRESCREEN to report_offsets, to show
+	  how similar the different tinfo configurations are.
+
+20180224
+	+ modify _nc_resolve_uses2() to detect incompatible types when merging
+	  a "use=" clause of extended capabilities.  The problem was seen in a
+	  defective terminfo integrated from simpleterm sources in 20171111,
+	  compounded by repair in 20180121.
+	+ correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
+	+ fix remaining flash capabilities with trailing mandatory delays -TD
+	+ correct cut/paste in NEWS (report by Sven Joachim).
+
+20180217
+	+ remove incorrect free() from 20170617 changes (report by David Macek).
+	+ correct type for "U8" in user_caps.5; it is a number not boolean.
+	+ add a null-pointer check in safe_sprintf.c (report by Steven Noonan).
+	+ improve fix for Debian #882620 by reusing limit2 variable (report by
+	  Julien Cristau, Sven Joachim).
+
+20180210
+	+ modify misc/Makefile.in to install/uninstall explicit list in case
+	  the build-directory happens to have no ".pc" files when an uninstall
+	  is performed (report by Jeffrey Walton).
+	+ deprecate safe-sprintf, since the vsnprintf function, which does what
+	  was needed, was standardized long ago.
+	+ add several development/experimental options to development packages.
+	+ minor reordering of options in configure script to make the threaded
+	  and reentrant options distinct from the other extensions which are
+	  normally enabled.
+
+20180203

+	+ use xterm+x11mouse in iterm, iterm2, mlterm3 because xterm's 1006
+	  mode does not work with those programs.  konsole is debatable -TD
+	+ add "termite" entry (report by Markus Pfeiffer) -TD
+	> merge branch begun April 2, 2017 which provides these features:
+	+ support read/write new binary-format for terminfo which stores
+	  numeric capabilities as a signed 32-bit integer.  The test programs
+	  such as picsmap, ncurses were created or updated during 2017 to use
+	  this feature.
+	+ the new format is written by the wide-character configuration of
+	  tic when it finds a numeric capability larger than 32767.
+	+ other applications such as infocmp built with the wide-character
+	  ncurses library work as expected.
+	+ applications built with the "narrow" (8-bit) configuration will
+	  read the new format, but will limit those extended values to 32767.
+	+ in either wide/narrow configuration, the structure defined in
+	  term.h still uses signed 16-bit values.
+	+ because it is incompatible with the legacy (mid-1980s) binary format,
+	  a new magic value is provided for the "file" program.
+	+ the term.5 manual page is updated to describe this new format.
+	+ the limit on file-size for compiled terminfo is increased in the
+	  wide-character configuration to 32768.
+
+20180120
+	+ build-fix in picsmap.c for stdint.h existence.
+	+ add --disable-stripping option to configure scripts.
+	+ modify ncurses-examples to install test-scripts in the data directory.
+	+ work around tool-breakage in Debian 9 and later by invoking
+	  gprconfig to specify the C compiler to be used by gnatmake,
+	  and conditionally suppressing Library_Options line for static
+	  libraries.
+	+ bump the compat level for test-packages to 7, i.e., Debian 5.
+
+20180106
+	+ fixes for writing extended color pairs in putwin.
+	+ modify test/savescreen.c to add test patterns that exercise 88-,
+	  256-, etc., colors.
+	+ modify configure option --with-build-cc, adding clang, c89 and c99
+	  as possible default values.
+	+ modify ncurses-examples configure script to use pkg-config for the
+	  extra form/menu/panel libraries, to be more consistent with the
+	  handling of the curses/ncurses library.
+	+ modify test-packages for mingw to supply "pc" files.
+	+ modify gen-pkgconfig.in to list -lpthread as a private library when
+	  configured to access it via weak symbols.
+	+ simplify gen-pkgconfig.in, adding -ltinfo without the special linker
+	  checks because some versions of the linker simply hard-code the
+	  behavior.
+	+ update URLs for ncurses website to use https.
+	+ modify CF_CURSES_LIBS to fill in $cf_nculib_root in case the
+	  ncurses-examples are built with a system ncurses that lacks the
+	  standard "curses" symbolic link, as done by SuSE.  The symbol is
+	  needed to make a followup check for the pthread library work, and
+	  would be set properly using the options "--with-screen", etc.
+	+ generate misc/*.pc with "all" rule, as done for "sources" rule
+	  (report by Jeffrey Walton).
+
+20171230
+	+ build-fix for ncurses-examples with Fedora27, adding check for
+	  reset_color_pairs() -- not yet in Fedora's package.
+	+ consistently add $CFLAGS to $MK_SHARED_LIB symbol in configure
+	  script when the latter happens to use the C compiler rather than
+	  directly using the loader (report by Jeffrey Walton).
+	+ set ABI for upcoming 6.1 release in "*.map" files.  While there are
+	  some remaining internals to apply, no ABI-related changes are
+	  anticipated.
+	+ add configure --with-config-suffix option to work around filename
+	  conflict with Redhat packages versus test-packages.
+
+20171223
+	+ modify ncurses-examples to quiet const-warnings when building with
+	  PDCurses.
+	+ modify toe to not exit if unable to read a terminal description,
+	  e.g., if there is a permission problem.
+	+ minor fix for progs/toe.c, using _nc_free_termtype2.
+	+ assign 0 to pointer in _nc_tgetent_leak() after freeing it. Also
+	  avoid reusing pointer from previous successful call to tgetent
+	  if the latest call is unsuccessful (patch by Michael Schroeder,
+	  OpenSuSE #1070450).
+	+ minor fix for test/tracemunch, initialize $awaiting variable.
+
+20171216
+	+ repair template in test/package/ncurses-examples.spec (cf: 20171111).
+	+ improve tic's warning about the number of parameters tparm might use
+	  for u1-u9 by making a special case for u6.
+	+ improve curs_attr.3x discussion of color pairs.
+
+20171209
+	+ modify misc/ncurses-config.in to make output with --includedir
+	  consistent with --cflags, i.e., when --disable-overwrite option was
+	  configured the output should show the subdirectory where headers
+	  are.
+	+ modify MKlib_gen.sh to suppress macros when calling an "implemented"
+	  function in link_test.c
+	+ updated ftp-url used in test-packages, etc.
+	+ modify order of -pie/-shared options in configure script in case
+	  LDFLAGS uses "-pie", working around a defect or limitation in the GNU
+	  linker (prompted by patch by Yogesh Prasad, forwarded by Jay Shah).
+	+ add entry in man_db.renames for user_caps.5
+
+20171125
+	+ modify MKlib_gen.sh to avoid tracing result from getstr/getnstr
+	  before initialized.
+	+ add "-a" aspect-ratio option to picsmap.
+	+ add configure check for default path of rgb.txt, used in picsmap.
+	+ modify _nc_write_entry() to truncate too-long filename (report by
+	  Hosein Askari, Debian #882620).
+	+ build-fix for ncurses-examples with NetBSD curses:
+	  + it lacks the use_env() function.
+	  + it lacks libpanel; a recent change used the wrong ifdef symbol.
+	+ add a macro for is_linetouched() and adjust the function's return
+	  value to make it possible for most applications to check for an
+	  error-return (report by Midolikawa H).
+	+ additional manpage cleanup.
+	+ update config.guess, config.sub from
+		http://git.savannah.gnu.org/cgit/config.git
+
+20171118
+	+ add a note to curs_addch.3x on portability.
+	+ add a note to curs_pad.3x on the origin and portability of pads.

+	+ improve manpage macros (prompted by discussion in Debian #880551.
+	+ reviewed test-programs using KEY_RESIZE, made fixes to test/worm.c
+	+ add a "-d" option to picsmap for default-colors.
+	+ modify old terminology entry and a few other terminal emulators to
+	  account for xon -TD
+	+ correct sgr string for tmux, which used screen's "standout" code
+	  rather than the standard code (patch by Roman Kagan)
+	+ correct sgr/sgr0 strings in a few other cases reported by tic, making
+	  those correspond to the non-sgr settings where they differ, but
+	  otherwise use ECMA-48 consistently:
+	  jaixterm, aixterm, att5420_2, att4424, att500, decansi, d410-7b,
+	  dm80, hpterm, emu-220, hp2, iTerm2.app, mterm-ansi, ncrvt100an,
+	  st-0.7, vi603, vwmterm -TD
+	+ build-fix for diagnostics warning in lib_mouse.c for pre-5.0 versions
+	  of gcc which did not recognize the diagnostic "push" pragma (patch by

+	  available; add a "S" wide-character overlap test-screen.
+	+ modify test/ncurses.c C/c tests to allow for extended color pairs.
+	+ add endwin() call in error-returns from test/ncurses.c omitted in
+	  recent redesign of its menu (cf: 20170923).
+	+ improve install of hashed-db by removing the ".db" file as done for
+	  directory-tree terminal databases.
+	+ repair a few overlooked items in include/ncurses_defs from recent
+	  port/refactoring of test-programs (cf: 20170909).
+	+ add test/padview.c, to compare pads with direct updates in view.c
+
+20171021
+	+ modify test/view.c to expand tabs using the ncurses library rather
+	  than in the test-program.
+	+ remove very old SIGWINCH example in test/view.c, just use KEY_RESIZE.
+	+ add -T, -e, -f -m options to "dots" test-programs.
+	+ fix a few typos in usage-messages for test-programs.
+
+20171014
+	+ minor cleanup to test/view.c:
+	  + eliminate "-n" option by simply reading the whole file.
+	  + implement page up/down commands.
+	+ add check in tput for init/reset operands to ensure those use a
+	  terminal.
+	+ improve manual pages which discuss chtype, cchar_t types and the
+	  attribute values which can be stored in those types.
+	+ correct array-index when parsing "-T" command-line option in tabs
+	  program.
+	+ modify demo_new_pair.c to pass extended pairs to setcchar().
+	+ add test/dots_xcurses.c to illustrate a different approach used for
+	  extended colors which can be contrasted with dots_curses.c.
+	+ add a check in tic to note when a description uses non-mandatory
+	  delays without xon_xoff.  This is not an error, but some descriptions
+	  for a terminal emulator may use the combination incorrectly.
+
+20171007
+	+ modify "-T" option of clear and tput to call use_tioctl() to obtain
+	  the operating system's notion of the screensize if possible.
+	+ review/repair some exit-codes for tput, making usage-message exit
+	  with 2 rather than 1, and a failure to open terminal 4+errno.
+	+ amend check in tput, tabs and clear to allow those to use the
+	  database-only features in cron if a -T option gives a suitable
+	  terminal name (report by Lauri Tirkkonen).
+	+ correct an ifdef in test/ncurses.c for systems with soft-keys but
+	  not slk_color().

+	+ minor fixes for configure script from work on ncurses-examples and
+	  tin.
+	+ improve animation in test/xmas.c by adding a time-delay in blinkit().
+	+ modify several test programs to reflect that ncurses honors existing
+	  signal handlers in initscr(), while other implementations do not.
+	+ modify bs.c to make it easier to quit.
+	+ change ncurses-examples to use attr_t vs chtype to follow X/Open
+	  documentation more closely since Solaris xpg4-curses uses different
+	  values for WA_xxx vs A_xxx that rely on attr_t being an unsigned
+	  short.  Tru64 aka OSF1, HPUX, AIX did as ncurses does, equating the
+	  two sets.
+
+20170923
+	+ modify menu for test/ncurses.c to fit on 24-line screen.
+	+ build-fix for configure --with-caps=uwin

+	  which was inconsistent with the normal implementation.
+	+ save/restore cursor position in Undo_Justification(), matching
+	  behavior of Buffer_To_Window() (report by Leon Winter).
+	+ modify test/knight to provide the "slow" solution for small screens
+	  using "R", noting that Warnsdorf's method is easily done with "a".
+	+ modify several test-programs which call use_default_colors() to
+	  consistently do this only if "-d" option is given.
+	+ additional changes to test with non-standard variants of curses:
+	  + modify a loop limit in firework.c to work around absence of limit
+	    checks in some libraries.
+	  + fill the last row of a window with "?" in firstlast if waddch does
+	    not return ERR on the lower-right corner.
+	+ add checks in test/configure for some functions not in 4.3BSD curses.
+	+ fix a regression in test/configure (cf: 20170826).

+	+ fix a bug in repeat_char logic (cf: 20170729, report by Chris Clayton).
+
+20170826
+	+ fixes for "iterm2" (report by Leonardo Brondani Schenkel) -TD
+	+ corrected a warning from tic about keys which are the same, to skip
+	  over missing/cancelled values.

+	  special key.
+	+ improve checks in trim_sgr0, comp_parse.c and parse_entry.c, for
+	  cancelled string capabilities.
+	+ add check in _nc_parse_entry() for invalid entry name, setting the
+	  name to "invalid" to avoid problems storing entries.
+	+ add/improve checks in tic's parser to address invalid input
+	  + add a check in comp_scan.c to handle the special case where a
+	    nontext file ending with a NUL rather than newline is given to tic
+	    as input (Redhat #1484274).
+	  + allow for cancelled capabilities in _nc_save_str (Redhat #1484276).
+	  + add validity checks for "use=" target in _nc_parse_entry (Redhat
+	    #1484284).
+	  + check for invalid strings in postprocess_termcap (Redhat #1484285)
+	  + reset secondary pointers on EOF in next_char() (Redhat #1484287).
+	  + guard _nc_safe_strcpy() and _nc_safe_strcat() against calls using
+	    cancelled strings (Redhat #1484291).
+	+ correct typo in curs_memleaks.3x (Sven Joachim).
+	+ improve test/configure checks for some curses variants not based on
+	  X/Open Curses.
+	+ add options for test/configure to disable checks for form, menu and
+	  panel libraries.
+
+20170819
+	+ update "iterm" entry -TD
+	+ add "iterm2" entry (report by Leonardo Brondani Schenkel) -TD
+	+ regenerate llib-* files.
+	+ regenerate HTML manpages.
+	+ improve picsmap test-program:
+	  + reduce memory used for tsearch
+	  + add report in log file showing cumulative color coverage.
+	+ add -x option to clear/tput to make the E3 extension optional
+	  (cf: 20130622).
+	+ add options -T and -V to clear command for compatibility with tput.
+	+ add usage message to clear command (Debian #371855).
+	+ improve usage messages for tset and tput.
+	+ minor fixes to "RGB" extension and reset_color_pairs().
+
+20170812
+	+ improve description of -R option in infocmp manual page (report by
+	  Stephane Chazelas).
+	+ add reset_color_pairs() function.
+	+ add user_caps.5 manual page to document the terminfo extensions used
+	  by ncurses.
+	+ improve build scripts, using SIGQUIT vs SIGTRAP; add other configure
+	  script fixes from work on xterm, lynx and tack.
+	+ modify install-rule for ncurses-examples to put the data files in
+	  /usr/share/ncurses-examples
+	+ improve tracemunch, by changing address-parameters of add_wch(),
+	  color_content() and pair_content() to dummy parameters.
+	+ minor optimization to _nc_change_pair, to return quickly when the
+	  current screen is marked for clearing.
+	+ in-progress changes to improve performance of test/picsmap.c for
+	  loading image files.
+	+ modify allocation for SCREEN's color-pair table to start small, grow
+	  on demand up to the existing limit.
+	+ add "RGB" extension capability for direct-color support, use this to
+	  improve color_content().
+	+ improve picsmap test-program:
+	  + if no palette file is needed, attempt to load one based on $TERM,
+	    checking first in the current directory, then by adding ".dat"
+	    suffix, and finally in the data-directory, e.g.,
+	    /usr/share/ncurses-examples
+	  + add "-l" option for logging
+	  + add "-d" option for debugging
+	  + add "-s" option for stepping automatically through list of images,
+	    with time delay.
+	  + use tsearch to improve time for loading color table for images.
+	+ update config.guess, config.sub from
+		http://git.savannah.gnu.org/cgit/config.git
+
+20170729
+	+ update interix entry using tack and SFU on Windows 7 Ultimate -TD
+	+ use ^? for kdch1 in interix (reported by Jonathan de Boyne Pollard)
+	+ add "rep" to xterm-new, available since 1997/01/26 -TD
+	+ move SGR 24 and 27 from vte-2014 to vte-2012 (request by Alain
+	  Williams) -TD
+	+ add a check in newline_forces_scroll() in case a program moves the
+	  cursor outside scrolling margins (report by Robert King).
+	+ improve _nc_tparm_analyze, using that to extend the checks made by
+	  tic for reporting inconsistencies between the expected number of
+	  parameters for a capability and the actual.
+	+ amend handling of repeat_char capability in EmitRange (adapted from
+	  report/patch by Dick Wesseling):
+	  + translate the character to the alternate character set when the
+	    alternate character set is enabled.
+	  + do not use repeat_char for characters past 255.
+	+ document "_nc_free_tinfo" in manual page, because it could be used in
+	  tack for memory-leak checking.
+	+ add "--without-tack" configure option to refine "--with-progs"
+	  configure option.  Normally tack is no longer built in-tree, but
+	  a few packagers combine it during the build.  If term_entry.h is
+	  installed, there is no advantage to in-tree builds.
+	+ adjust configure-script to define HAVE_CURSES_DATA_BOOLNAMES symbol
+	  needed for tack 1.08 when built in-tree.  Rather than relying upon
+	  internal "_nc_" functions, tack now uses the boolean, number and
+	  string capability name-arrays provided by ncurses and SVr4 Unix
+	  curses.  It still uses term_entry.h for the definitions of the
+	  extended capability arrays.
+	+ add an overlooked null-pointer check in mvcur changes from 20170722
+
+20170722
+	+ improve test-packages for ncurses-examples and AdaCurses for lintian
+	+ modify logic for endwin-state to be able to detect the case where
+	  the screen was never initialized, using that to trigger a flush of
+	  ncurses' buffer for mvcur, e.g., in test/dots_mvcur.c for the
+	  term-driver configuration.
+	+ add dependency upon ncurses_cfg.h to a few other internal header
+	  files to allow each to be compiled separately.
+	+ add dependency upon ncurses_cfg.h to tic's header-files; any program
+	  using tic-library will have to supply this file.  Legacy tack
+	  versions supply this file; ongoing tack development has dropped the
+	  dependency upon tic-library and new releases will not be affected.
+
+20170715
+	+ modify command-line parameters for "convert" used in picsmap to work
+	  with ImageMagick 6.8 and newer.
+	+ fix build-problem with tack and ABI-5 (Debian #868328).
+	+ repair termcap-format from tic/infocmp broken in 20170701 fixes
+	  (Debian #868266).
+	+ reformat terminfo.src with 20170513 updates.
+	+ improve test-packages to address lintian warnings.
+
+20170708
+	+ add a note to tic manual page about -W versus -f options.
+	+ correct a limit-check in fixes from 20170701 (report by Sven Joachim).
+
+20170701
+	+ modify update_getenv() in db_iterator.c to ensure that environment
+	  variables which are not initially set will be checked later if an
+	  application happens to set them (patch by Guillaume Maudoux).
+	+ remove initialization-check for calling napms() in the term-driver
+	  configuration; none is needed.
+	+ add help-screen to test/test_getstr.c and test/test_get_wstr.c
+	+ improve compatibility between different configurations of new_prescr,
+	  fixing a case with threaded code and term-driver where c++/demo did
+	  not work (cf: 20160213).
+	+ the fixes for Redhat #1464685 obscured a problem subsequently
+	  reported in Redhat #1464687; the given test-case was no longer
+	  reproducible.  Testing without the fixes for the earlier reports
+	  showed a problem with buffer overflow in dump_entry.c, which is
+	  addressed by reducing the use of a fixed-size buffer.
+	+ add/improve checks in tic's parser to address invalid input
+	  (Redhat #1464684, #1464685, #1464686, #1464691).
+	  + alloc_entry.c, add a check for a null-pointer.
+	  + parse_entry.c, add several checks for valid pointers as well as
+	    one check to ensure that a single character on a line is not
+	    treated as the 2-character termcap short-name.
+	+ fix a memory leak in delscreen() (report by Bai Junq).
+	+ improve tracemunch, showing thread identifiers as names.
+	+ fix a use-after-free in NCursesMenu::~NCursesMenu()
+	+ further amend incorrect calls for memory-leaks from 20170617 changes
+	  (report by Allen Hewes).
+
+20170624
+	+ modify c++/etip.h.in to accommodate deprecation of throw() and
+	  throws() in c++17 (prompted by patch by Romain Geissler).
+	+ remove some incorrect calls for memory-leaks from 20170617 changes
+	  (report by Allen Hewes).
+	+ add test-programs for termattrs and term_attrs.
+	+ modify _nc_outc_wrapper to use the standard output if the screen was
+	  not initialized, rather than returning an error.
+	+ improve checks for low-level terminfo functions when the terminal
+	  has not been initialized (Redhat #1345963).
+	+ modify make_hash to allow building with address-sanitizer,
+	  assuming that --disable-leaks is configured.
+	+ amend changes for number_format() in 20170506 to avoid undefined
+	  behavior when shifting (patch by Emanuele Giaquinta).
+
+20170617
+	+ fill in some places where TERMTYPE2 vs TERMTYPE was not used
+	  (report by Allen Hewes).
+	+ use ExitTerminfo() internally in error-exits for ncurses' setupterm
+	  to help with leak checking.
+	+ use ExitProgram() in error-exit from initscr() to help with leak
+	  checking.
+	+ review test-programs, adding checks for cases where the terminal
+	  cannot be initialized.
+
+20170610
+	+ add option "-xp" to picsmap.c, to use init_extended_pair().
+	+ make simple performance fixes for picsmap.c
+	+ improve aspect ratio of images read from "convert" in picsmap.c
+
+20170603
+	+ add option to picsmap to use color-palette files, e.g., for mapping
+	  to xterm-256color.
+	+ move the data in SCREEN used for the alloc_pair() function to the
+	  end, to restore compatibility between ncurses/ncursesw libtinfo
+	  (report/patch by Miroslav Lichvar).
+	+ add build-time utility "report_offsets" to help show when the various
+	  configurations of tinfo library are compatible or not.
+
+20170527
+	+ improved test/picsmap.c:
+	  + lookup named colors for xpm files in rgb.txt
+	  + accept blanks in color-keys for xpm files.
+	  + if neither xbm/xpm work, try "convert", which may be available.
+
+20170520
+	+ modify test/picsmap.c to read xpm files.
+	+ modify package/debian/* to create documentation packages, so the
+	  related files can be checked with lintian.
+	+ fix some typos in manpages (report/patch by Sven Joachim).
+
+20170513
+	+ add test/picsmap.c to fill in some testing issues not met by dots.
+	  The initial version reads X bitmap (".xbm") files.
+	+ repair logic which forces a repaint where a color-pair's content is
+	  changed (cf: 20170311).
+	+ improve tracemunch, showing screenXX pointers as names.
+
+20170506
+	+ modify tic/infocmp display of numeric values to use hexadecimal when
+	  they are "close" to a power of two, making the result more readable.
+	+ improve discussion of portability in curs_mouse.3x
+	+ change line-length for generated html/manpages to 78 columns from 65.
+	+ improve discussion of line-drawing characters in curs_add_wch.3x
+	  (prompted by discussion with Lorinczy Zsigmond).
+	+ cleanup formatting of hackguide.html and ncurses-intro.html
+	+ add examples for WACS_D_PLUS and WACS_T_PLUS to test/ncurses.c
+
+20170429
+	+ corrected a case where $with_gpm was set to "maybe" after CF_WITH_GPM,
+	  overlooked in 20160528 fixes (report by Alexandre Bury).
+	+ improve a couple of test-program's help-messages.
+	+ corrected loop in rain.c from 20170415 changes.
+	+ modify winnstr and winchnstr to return error if the output pointer is
+	  null, as well as adding a null pointer check of the window pointer
+	  for better compatibility with other implementations.
+	+ improve discussion of NetBSD curses in scr_dump.5
+	+ modify LIMIT_TYPED macro in new_pair.h to avoid changing sign of the
+	  value to be limited (reports by Darby Payne, Rob Boudreau).
+	+ update config.guess, config.sub from
+		http://git.savannah.gnu.org/cgit/config.git
+
+20170422
+	+ build-fix for termcap-configuration (report by Chi-Hsuan Yen).
+	+ improve terminfo manual page discussion of control- and graphics-
+	  characters.
+	+ remove tic warning about "^?" in string capabilities, which was
+	  marked as an extension (cf: 20000610, 20110820); however all Unix
+	  implementations support this and X/Open Curses does not address it.
+	  On the other hand, termcap never did support this feature.
+	+ correct missing comma-separator between string capabilities in
+	  icl6402 and m2-nam -TD
+	+ restore rmir/smir in ansi+idc to better match original ansiterm+idc,
+	  add alias ansiterm (report by Robert King).
+	+ amend an old check for ambiguous use of "ma" in terminfo versus
+	  a termcap use, if the capability is cancelled to treat it as number.
+	+ correct a case in _nc_captoinfo() which read "%%" and emitted "%".
+	+ modify sscanf calls in _nc_infotocap() for patterns "%{number}%+%c"
+	  and "%'char'%+%c" to check that the final character is really 'c',
+	  avoiding a case in icl6404 which cannot be converted to termcap.
+	+ in _nc_infotocap(), add a check to ensure that terminfo "^?" is not
+	  written to termcap, because the BSDs did not implement that.
+	+ in _nc_tic_expand() and _nc_infotocap(), improve string-length check
+	  when deciding whether to use "^X" or "\xxx" format for control
+	  characters, to make the output of tic/infocmp more predictable.
+	+ limit termcap "%d" width to 2 digits on input, and use "%2" in
+	  preference to "%02" on output.
+	+ correct terminfo/termcap conversion of "%02" and "%03" into "%2" and
+	  "%3"; the result repeated the last character.
+	+ add man/scr_dump.5 to document screen-dump format.
+
+20170415
+	+ modify several test programs to use new popup_msgs, adapted from
+	  help-screen used in test/edit_field.c
+	+ drop two symbols obsoleted in 2004: _nc_check_termtype, and
+	  _nc_resolve_uses
+	+ fix some old copyright dates (cf: 20031025).
+	+ build-fixes for test/savescreen.c to work with AIX and HPUX.
+	+ minor fix to configure script, adding a backslash/continuation.
+	+ extend TERMINAL structure for ABI 6 to store numbers internally as
+	  integers rather than short, by adding new data for this purpose.
+	+ more fixes for minor memory-leaks in test-programs.
+
+20170408
+	+ change logic in wins_nwstr() to avoid addressing data past the output
+	  of mbstowcs().
+	+ correct a call to setcchar() in Data_Entry_w() from 20131207 changes.
+	+ fix minor memory-leaks in test-programs.
+	+ further improve ifdef in term_entry.h for internal definitions not
+	  used by tack.
+
+20170401
+	+ minor fixes for vt100+4bsd, e.g., delay in sgr for consistency -TD
+	+ add smso for env230, to match sgr -TD
+	+ remove p7/protect from sgr in fbterm -TD
+	+ drop setf/setb from fbterm; setaf/setab are enough -TD
+	+ make xterm-pcolor sgr consistent with other capabilities -TD
+	+ add rmxx/smxx ECMA-48 strikeout extension to tmux and xterm-basic
+	  (discussion with Nicholas Marriott)
+	+ add test-programs sp_tinfo and extended_color
+	+ modify no-leaks code for lib_cur_term.c to account for the tgetent()
+	  cache.
+	+ modify setupterm() to save original tty-modes so that erasechar()
+	  works as expected.  Also modify _nc_setupscreen() to avoid redundant
+	  calls to get original tty-modes.
+	+ modify set_curterm() to update ttytype[] data used by longname().
+	+ modify wattr_set() and wattr_get() to return ERR if win-parameter is
+	  null, as documented.
+	+ improve cast used for null-pointer checks in header macros, to
+	  reduce compiler warnings.
+	+ modify several functions, using the reserved "opts" parameter to pass
+	  color- and pair-values larger than 16-bits:
+	  + getcchar(), setcchar(), slk_attr_set(), vid_puts(), wattr_get(),
+	    wattr_set(), wchgat(), wcolor_set().
+	  + Other functions call these with the corresponding altered behavior,
+	    including chgat(), mvchgat(), mvwchgat(), slk_color_on(),
+	    slk_color_off(), vid_attr().
+	+ add new functions for manipulating color- and pair-values larger
+	  than 16-bits.  These are extended_color_content(),
+	  extended_pair_content(), extended_slk_color(), init_extended_color(),
+	  init_extended_pair(), and the corresponding sp-funcs.
+
+20170325
+	+ fix a memory leak in the window-list when creating multiple screens
+	  (reports by Andres Martinelli, Debian #783486).
+	+ reviewed calls from link_test.c, added a few more null-pointer
+	  checks.
+	+ add a null-pointer check in ungetmouse, in case mousemask was not
+	  called (report by "Kau").
+	+ updated curs_sp_funcs.3x for new functions.
+
+20170318
+	+ change TERMINAL structure in term.h to make it opaque.  Some
+	  applications misuse its members, e.g., directly modifying it
+	  rather than using def_prog_mode().
+	+ modify utility headers such as tic.h to make it clearer which are
+	  externals that are used by tack.
+	+ improve curs_slk.3x in particular its discussion of portability.
+	+ fix cut/paste in legacy_encoding.3x
+	+ add prototype for find_pair() to new_pair.3x (report by Branden
+	  Robinson).
+	+ fix a couple of broken links in generated man-html documentation.
+	+ regenerate man-html documentation.
+
+20170311
+	+ modify vt100 rs2 string to reset vt52 mode and scrolling regions
+	  (report/analysis by Robert King) -TD
+	+ add vt100+4bsd building block, use that for older terminals rather
+	  than "vt100" which is now mostly used as a building block for
+	  terminal emulators -TD
+	+ correct a few spelling errors in terminfo.src comments -TD
+	+ add fbterm -TD
+	+ fix a typo in ncurses.c test_attr legend (patch by Petr Vanek).
+	+ changed internal colorpair_t to a struct, eliminating an internal
+	  8-bit limit on colors
+	+ add ncurses/new_pair.h
+	+ add ncurses/base/new_pair.c with alloc_pair(), find_pair() and
+	  free_pair() functions

+	  error.
+	+ fix a typo in include/hashed_db.h (Andre Sa).
+
+20170225
+	+ fixes for CF_CC_ENV_FLAGS (report by Ross Burton).
+
+20170218
+	+ fix several formatting issues with manual pages.
+	+ correct read of terminfo entry in which all strings are absent or
+	  explicitly cancelled.  Before this fix, the result was that all were
+	  treated as only absent.
+	+ modify infocmp to suppress mixture of absent/cancelled capabilities
+	  that would only show as "NULL, NULL", unless the -q option is used,
+	  e.g., to show "-, @" or "@, -".
+
+20170212
+	+ build-fixes for PGI compilers (report by Adam J. Stewart)
+	  + accept whitespace in sed expression for generating expanded.c
+	  + modify configure check that g++ compiler warnings are not used.
+	  + add configure check for -fPIC option needed for shared libraries.
+	+ let configure --disable-ext-funcs override the default for the
+	  --enable-sp-funcs option.
+	+ mark some structs in form/menu/panel libraries as potentially opaque
+	  without modifying API/ABI.
+	+ add configure option --enable-opaque-curses for ncurses library and
+	  similar options for the other libraries.
+
+20170204
+	+ trim newlines, tabs and escaped newlines from terminfo "paths" passed
+	  to db-iterator.
+	+ ignore zero-length files in db-iterator; these are useful for
+	  instance to suppress "$HOME/.terminfo" when not wanted.
+	+ amended "b64:" encoder to work with the terminfo reader.
+	+ modify terminfo reader to accept "b64:" format using RFC-3548 in
+	  as well as RFC-4648 url/filename-safe format.
+	+ modify terminfo reader to accept "hex:" format as generated by
+	  "infocmp -0qQ1" (cf: 20150905).
+	+ adjust authors comment to reflect drop below 1% for SV.
+
+20170128
+	+ minor comment-fixes to help automate links to bug-urls -TD
+	+ add dvtm, dvtm-256color -TD
+	+ add settings corresponding to xterm-keys option to tmux entry to
+	  reflect upcoming change to make that option "on" by default
+	  (patch by Nicholas Marriott).
+	+ uncancel Ms in tmux entry (Harry Gindi, Nicholas Marriott).
+	+ add dumb-emacs-ansi -TD
+
+20170121
+	+ improve discussion of early history of tput program.
+	+ incorporate A_COLOR mask into COLOR_PAIR(), in case user application
+	  provides an out-of-range pair number (report by Elijah Stone).
+	+ clarify description in tput manual page regarding support for
+	  termcap names (prompted by FreeBSD #214709).
+	+ remove a restriction in tput's support for termcap names which
+	  omitted capabilities normally not shown in termcap translations
+	  (cf: 990123).
+	+ modify configure script for clang as used on FreeBSD, to work around
+	  clang's differences in exit codes vs gcc.
+
+20170114
+	+ improve discussion of early history of tset/reset programs.
+	+ clarify in manual pages that the optional verbose option level is
+	  available only when ncurses is configured for tracing.
+	+ amend change from 20161231 to avoid writing traces to the standard
+	  error after initializing the trace feature using the environment
+	  variable.
+
+20170107
+	+ amend changes for tput to reset tty modes to "sane" if the program
+	  is run as "reset", like tset.  Likewise, ensure that tset sends
+	  either reset- or init-strings.
+	+ improve manual page descriptions of tput init/reset and tset/reset,
+	  to make it easier to see how they are similar and different.
+	+ move a static result from key_name() to _nc_globals
+	+ modify _nc_get_screensize to allow for use_env() and use_tioctl()
+	  state to be per-screen when sp-funcs are configured, better matching
+	  the behavior when using the term-driver configuration.
+	+ improve cross-references in manual pages for often used functions
+	+ move SCREEN field for use_tioctl() data before the ncursesw fields,
+	  and limit that to the sp-funcs configuration to improve termlib
+	  compatibility (cf:  20120714).
+	+ correct order of initialization for traces in use_env() and
+	  use_tioctl() versus first trace calls.
+
+20161231
+	+ fix errata for ncurses-howto (report by Damien Ruscoe).
+	+ fix a few places in configure/build scripts where DESTDIR and rpath
+	  were combined (report by Thomas Klausner).
+	+ merge current st description (report by Harry Gindi) -TD
+	+ modify flash capability for linux and wyse entries to put the delay
+	  between the reverse/normal escapes rather than after -TD
+	+ modify program tabs to pass the actual tty file descriptor to
+	  setupterm rather than the standard output, making padding work
+	  consistently.
+	+ explain in clear's manual page that it writes to stdout.
+	+ add special case for verbose debugging traces of command-line
+	  utilities which write to stderr (cf: 20161126).
+	+ remove a trace with literal escapes from skip_DECSCNM(), added in
+	  20161203.
+	+ update config.guess, config.sub from
+		http://git.savannah.gnu.org/cgit/config.git
+
+20161224
+	+ correct parameters for copywin call in _nc_Synchronize_Attributes()
+	  (patch by Leon Winter).
+	+ improve color-handling section in terminfo manual page (prompted by
+	  patch by Mihail Konev).
+	+ modify programs clear, tput and tset to pass the actual tty file
+	  descriptor to setupterm rather than the standard output, making
+	  padding work.
+
+20161217
+	+ add tput-colorcube demo script.
+	+ add -r and -s options to tput-initc demo, to match usage in xterm.
+	+ flush the standard output in _nc_flush for the case where SP is zero,
+	  e.g., when called via putp.  This fixes a scenario where "tput flash"
+	  did not work after changes in 20130112.
+
+20161210
+	+ add configure script option --disable-wattr-macros for use in cases
+	  where one wants to use the same headers for ncurses5/ncurses6
+	  development, by suppressing the wattr* macros which differ due to
+	  the introduction of extended colors (prompted by comments in
+	  Debian #230990, Redhat #1270534).
+	+ add test/tput-initc to demonstrate tput used to initialize palette
+	  from a data file.
+	+ modify test/xterm*.dat to use the newer color4/color12 values.
+
+20161203
+	+ improve discussion of field validation in form_driver.3x manual page.
+	+ update curs_trace.3x manual page.

+	+ modify linux-16color to not mask dim, standout or reverse with the
+	  ncv capability -TD
+	+ add 0.1sec mandatory delay to flash capabilities using the VT100
+	  reverse-video control -TD
+	+ omit selection of ISO-8859-1 for G0 in enacs capability from linux2.6
+	  entry, to avoid conflict with the user-defined mapping.  The reset
+	  feature will use ISO-8859-1 in any case (Mikulas Patocka).
+	+ improve check in tic for delays by also warning about beep/flash
+	  when a delay is not embedded, or if those use the VT100 reverse
+	  video escape without using a delay.
+	+ minor fix for syntax-check of delays from 20161119 changes.
+	+ modify trace() to avoid overwriting existing file (report by Maor
+	  Shwartz).
+
+20161119
+	+ add check in tic for some syntax errors of delays, as well as use of
+	  proportional delays for non-line capabilities.
+	+ document history of the clear program and the E3 extension, prompted
+	  by various discussions including
+	  http://unix.stackexchange.com/questions/87469/clearing-the-old-scrollback-buffer
+
+20161112
+	+ improve -W option in tic/infocmp:
+	  + correct order of size-adjustments in wrapped lines
+	  + if -f option splits line, do not further split it with -W
+	  + begin a new line when adding "use=" after a wrapped line
+
+20161105
+	+ fix typo in man/terminfo.tail (Alain Williams).
+	+ correct program-name in adacurses6-config.1 manual page.
+
+20161029
+	+ add new function "unfocus_current_field" (Leon Winter)
+
+20161022
+	+ modify tset -w (and tput reset) to update the program's copy of the
+	  screensize if it was already set in the system, to improve tabstop
+	  setting which relies upon knowing the actual screensize.
+	+ add functionality of tset -w to tput, like the "-c" feature this is
+	  not optional in tput.
+	+ add "clear" as a possible link/alias to tput.
+	+ improve tput's check for being called as "init" or "reset" to allow
+	  for transformed names.
+	+ split-out the "clear" function from progs/clear.c, share with
+	  tput to get the same behavior, e.g., the E3 extension.
+
+20161015
+	+ amend internal use of tputs to consistently use the number of lines
+	  affected, e.g., for insert/delete character operations.  While
+	  merging terminfo source early in 1995, several descriptions used the
+	  "*" proportional delay for these operations, prompting a change in
+	  doupdate.
+	+ regenerate llib-* files.
+	+ regenerate HTML manpages.
+	+ fix several formatting issues with manual pages.
+
+20161008
+	+ adjust size in infocmp/tic to work with strlcpy.
+	+ fix configure script to record when strlcat is found on OpenBSD.
+	+ build-fix for "recent" OpenBSD vs baudrate.
+
+20161001
+	+ add -W option to tic/infocmp to force long strings to wrap.  This is
+	  in addition to the -w option which attempts to fit capabilities into
+	  a given line-length.
+	+ add linux-m1 minitel entries (patch by Alexandre Montaron).
+	+ correct rs2 string for vt100-nam -TD
+
+20160924
+	+ modify _nc_tic_expand to escape comma if it immediately follows a
+	  percent sign, to work with minitel change.
+	+ updated minitel and viewdata descriptions (Alexandre Montaron).
+
+20160917
+	+ build-fix for gnat6, which unhelpfully attempts to compile C files.
+	+ fix typo in 20160910 changes (Debian #837892, patch by Sven Joachim).
+
+20160910
+	+ trim dead code ifdef'd with HIDE_EINTR since 970830 (discussion with
+	  Leon Winter).
+	+ trim some obsolete/incorrect wording about EINTR from wgetch manual
+	  page (patch by Leon Winter).
+	+ really correct 20100515 change (patch by Rich Coe).
+	+ add "--enable-string-hacks" option to test/configure
+	+ completed string-hacks for "sprintf", etc., including test-programs.
+	+ make "--enable-string-hacks" work with Debian by checking for the
+	  "bsd" library and its associated "<bsd/string.h>" header.
+
+20160903
+	+ correct 20100515 change for weak signals versus sigprocmask (report
+	  by Rich Coe).
+	+ modify misc/Makefile.in to work around OpenBSD "make" which unlike
+	  all other versions of "make" does not recognize continuation lines
+	  of comments.
+	+ amend the last change to CF_C_ENV_FLAGS to move only the
+	  preprocessor, optimization and warning flags to CPPFLAGS and CFLAGS,
+	  leaving the residue in CC.  That happens to work for gcc's various
+	  "model" options, but may require tuning for other compilers (report
+	  by Sven Joachim).
+
+20160827
+	+ add "v" menu entry to test/ncurses.c to show baudrate and other
+	  values.
+	+ add "newer" baudrate symbols from Linux and FreeBSD to progs/tset.c,
+	  lib_baudrate.c
+	+ modify CF_XOPEN_SOURCE macro:
+	  + add "uclinux" to case for "linux" (patch by Yann E. Morin)
+	  + modify _GNU_SOURCE for cygwin headers, tested with cygwin 2.3, 2.5
+	    (patch by Corinna Vinschen, from changes to tin).
+	+ improve CF_CC_ENV_FLAGS macro to allow for compiler wrappers such
+	  as "ccache" (report by Enrico Scholz).
+	+ update config.guess, config.sub from
+		http://git.savannah.gnu.org/cgit/config.git
+
+20160820
+	+ update tput manual page to reflect changes to manipulate terminal
+	  modes by sharing functions with tset.
+	+ add the terminal-mode parts of "reset" (aka tset) to the "tput reset"
+	  command, making the two almost the same except for window-size.
+	+ adapt logic used in dialog "--keep-tite" option for test/filter.c as
+	  "-a" option.  When set, test/filter attempts to suppress the
+	  alternate screen.
+	+ correct a typo in interix entry -TD
+
+20160813
+	+ add a dependency upon generated-sources in Ada95/src/Makefile.in to
+	  handle a case of "configure && make install".
+	+ trim trailing blanks from include/Caps*, to work around a problem
+	  in sed (Debian #818067).
+
+20160806
+	+ improve CF_GNU_SOURCE configure macro to optionally define
+	  _DEFAULT_SOURCE work around a nuisance in recent glibc releases.
+	+ move the terminfo-specific parts of tput's "reset" function into
+	  the shared reset_cmd.c, making the two forms of reset use the same
+	  strings.
+	+ split-out the terminal initialization functions from tset as
+	  progs/reset_cmd.c, as part of changes to merge the reset-feature
+	  with tput.
+
+20160730
+	+ change tset's initialization to allow it to get settings from the
+	  standard input as well as /dev/tty, to be more effective when
+	  output or error are redirected.
+	+ improve discussion of history and portability for tset/reset/tput
+	  manual pages.
+
+20160723
+	+ improve error message from tset/reset when both stderr/stdout are
+	  redirected to a file or pipe.
+	+ improve organization of curs_attr.3x, curs_color.3x
+
+20160709
+	+ work around Debian's antique/unmaintained version of mawk when
+	  building link_test.
+	+ improve test/list_keys.c, showing ncurses's convention of modifiers
+	  for special keys, based on xterm.
+
+20160702
+	+ improve test/list_keys.c, using $TERM if no parameters are given.
+
+20160625
+	+ build-fixes for ncurses "test_progs" rule.
+	+ amend change to CF_CC_ENV_FLAGS in 20160521 to make multilib build
+	  work (report by Sven Joachim).
+
+20160618
+	+ build-fixes for ncurses-examples with NetBSD curses.
+	+ improve test/list_keys.c, fixing column-widths and sorting the list
+	  to make it more readable.
+
+20160611
+	+ revise fix for Debian #805618 (report by Vlado Potisk, cf: 20151128).
+	+ modify test/ncurses.c a/A screens to make exiting on an escape
+	  character depend on the start of keypad and timeout modes, to allow
+	  better testing of function-keys.
+	+ modify rs1 for xterm-16color, xterm-88color and xterm-256color to
+	  reset palette using "oc" string as in linux -TD
+	+ use ANSI reply for u8 in xterm-new, to reflect vt220-style responses
+	  that could be returned -TD
+	+ added a few capabilities fixed in recent vte -TD
+
+20160604
+	+ correct logic for -f option in test/demo_terminfo.c
+	+ add test/list_keys.c
+
+20160528
+	+ further workaround for PIE/PIC breakage which causes gpm to not link.
+	+ fix most cppcheck warnings, mostly style, in ncurses library.
+
+20160521
+	+ improved manual page description of tset/reset versus window-size.
+	+ fixes to work with a slightly broken compiler configuration which
+	  cannot compile "Hello World!" without adding compiler options
+	  (report by Ola x Nilsson):
+	  + pass appropriate compiler options to the CF_PROG_CC_C_O macro.
+	  + when separating compiler and options in CF_CC_ENV_FLAGS, ensure
+	    that all options are split-off into CFLAGS or CPPFLAGS
+	  + restore some -I options removed in 20140726 because they appeared
+	    to be redundant.  In fact, they are needed for a compiler that
+	    cannot combine -c and -o options.
+
+20160514
+	+ regenerate HTML manpages.
+	+ improve manual pages for wgetch and wget_wch to point out that they
+	  might return values without names in curses.h (Debian #822426).
+	+ make linux3.0 entry the default linux entry (Debian #823658) -TD
+	+ modify linux2.6 entry to improve line-drawing so that the linux3.0
+	  entry can be used in non-UTF-8 mode -TD
+	+ document return value of use_extended_names (report by Mike Gran).
+
+20160507
+	+ amend change to _nc_do_color to restore the early return for the
+	  special case used in _nc_screen_wrap (report by Dick Streefland,
+	  cf: 20151017).
+	+ modify test/ncurses.c:
+	  + check return-value of putwin
+	  + correct ifdef which made the 'g' test's legend not reflect changes
+	    to keypad- and scroll-modes.
+	+ correct return-value of extended putwin (report by Mike Gran).
+
+20160423
+	+ modify test/ncurses.c 'd' edit-color menu to optionally read xterm
+	  color palette directly from terminal, as well as handling KEY_RESIZE
+	  and screen-repainting with control/L and control/R.
+	+ add 'oc' capability to xterm+256color, allowing palette reset for
+	  xterm -TD
+
+20160416
+	+ add workaround in configure script for inept transition to PIE vs
+	  PIC builds documented in
+		  https://fedoraproject.org/wiki/Changes/Harden_All_Packages
+	+ add "reset" to list of programs whose names might change in manpages
+	  due to program-transformation configure options.
+	+ drop long-obsolete "-n" option from tset.
+
+20160409
+	+ modify test/blue.c to use Unicode values for card-glyphs when
+	  available, as well as improving the check for CP437 and CP850.
+
+20160402
+	+ regenerate HTML manpages.
+	+ improve manual pages for utilities with respect to POSIX versus
+	  X/Open Curses.
+
+20160326
+	+ regenerate HTML manpages.
+	+ improve test/demo_menus.c, allowing mouse-click on the menu-headers
+	  to switch the active menu.  This requires a new extension option
+	  O_MOUSE_MENU to tell the menu driver to put mouse events which do not
+	  apply to the active menu back into the queue so that the application
+	  can handle the event.
+
+20160319
+	+ improve description of tgoto parameters (report by Steffen Nurpmeso).
+	+ amend workaround for Solaris line-drawing to restore a special case
+	  that maps Unicode line-drawing characters into the acsc string for
+	  non-Unicode locales (Debian #816888).
+
+20160312
+	+ modified test/filter.c to illustrate an alternative to getnstr, that
+	  polls for input while updating a clock on the right margin as well
+	  as responding to window size-changes.
+
+20160305
+	+ omit a redefinition of "inline" when traces are enabled, since this
+	  does not work with gcc 5.3.x MinGW cross-compiling (cf: 20150912).
+
+20160220
+	+ modify test/configure script to check for pthread dependency of
+	  ncursest or ncursestw library when building ncurses examples, e.g.,
+	  in case weak symbols are used.
+	+ modify configure macro for shared-library rules to use -Wl,-rpath
+	  rather than -rpath to work around a bug in scons (FreeBSD #178732,
+	  cf: 20061021).
+	+ double-width multibyte characters were not counted properly in
+	  winsnstr and wins_nwstr (report/example by Eric Pruitt).
+	+ update config.guess, config.sub from
+		http://git.savannah.gnu.org/cgit/config.git
+
+20160213
+	+ amend fix for _nc_ripoffline from 20091031 to make test/ditto.c work
+	  in threaded configuration.
+	+ move _nc_tracebits, _tracedump and _tracemouse to curses.priv.h,
+	  since they are not part of the suggested ABI6.
+
+20160206
+	+ define WIN32_LEAN_AND_MEAN for MinGW port, making builds faster.
+	+ modify test/ditto.c to allow $XTERM_PROG environment variable to
+	  override "xterm" as the name of the program to run in the threaded
+	  configuration.
+
+20160130
+	+ improve formatting of man/curs_refresh.3x and man/tset.1 manpages
+	+ regenerate HTML manpages using newer man2html to eliminate some
+	  unwanted blank lines.
+
+20160123
+	+ ifdef'd header-file definition of mouse_trafo() with NCURSES_NOMACROS
+	  (report by Corey Minyard).
+	+ fix some strict compiler-warnings in traces.
+
+20160116
+	+ tidy up comments about hardcoded 256color palette (report by
+	  Leonardo Brondani Schenkel) -TD
+	+ add putty-noapp entry, and amend putty entry to use application mode
+	  for better consistency with xterm (report by Leonardo Brondani
+	  Schenkel) -TD
+	+ modify _nc_viscbuf2() and _tracecchar_t2() to trace wide-characters
+	  as a whole rather than their multibyte equivalents.
+	+ minor fix in wadd_wchnstr() to ensure that each cell has nonzero
+	  width.
+	+ move PUTC_INIT calls next to wcrtomb calls, to avoid carry-over of
+	  error status when processing Unicode values which are not mapped.
+
+20160102
+	+ modify ncurses c/C color test-screens to take advantage of wide
+	  screens, reducing the number of lines used for 88- and 256-colors.
+	+ minor refinement to check versus ncv to ignore two parameters of
+	  SGR 38 and 48 when those come from color-capabilities.
+
+20151226
+	+ add check in tic for use of bold, etc., video attributes in the
+	  color capabilities, accounting whether the feature is listed in ncv.
+	+ add check in tic for conflict between ritm, rmso, rmul versus sgr0.
+
+20151219
+	+ add a paragraph to curs_getch.3x discussing key naming (discussion
+	  with James Crippen).
+	+ amend workaround for Solaris vs line-drawing to take the configure
+	  check into account.
+	+ add a configure check for wcwidth() versus the ncurses line-drawing
+	  characters, to use in special-casing systems such as Solaris.
+
+20151212
+	+ improve CF_XOPEN_CURSES macro used in test/configure, to define as
+	  needed NCURSES_WIDECHAR for platforms where _XOPEN_SOURCE_EXTENDED
+	  does not work.  Also modified the test program to ensure that if
+	  building with ncurses, that the cchar_t type is checked, since that
+	  normally is since 20111030 ifdef'd depending on this test.
+	+ improve 20121222 workaround for broken acs, letting Solaris "work"
+	  in spite of its misconfigured wcwidth which marks all of the line
+	  drawing characters as double-width.
+
+20151205
+	+ update form_cursor.3x, form_post.3x, menu_attributes.3x to list
+	  function names in NAME section (patch by Jason McIntyre).
+	+ minor fixes to manpage NAME/SYNOPSIS sections to consistently use
+	  rule that either all functions which are prototyped in SYNOPSIS are
+	  listed in the NAME section, or the manual-page name is the sole item
+	  listed in the NAME section.  The latter is used to reduce clutter,
+	  e.g., for the top-level library manual pages as well as for certain
+	  feature-pages such as SP-funcs and threading (prompted by patches by
+	  Jason McIntyre).
+
+20151128
+	+ add option to preserve leading whitespace in form fields (patch by
+	  Leon Winter).
+	+ add missing assignment in lib_getch.c to make notimeout() work
+	  (Debian #805618).
+	+ add 't' toggle for notimeout() function in test/ncurses.c a/A screens
+	+ add viewdata terminal description (Alexandre Montaron).
+	+ fix a case in tic/infocmp for formatting capabilities where a
+	  backslash at the end of a string was mishandled.
+	+ fix some typos in curs_inopts.3x (Benno Schulenberg).
+
+20151121
+	+ fix some inconsistencies in the pccon* entries -TD
+	+ add bold to pccon+sgr+acs and pccon-base (Tati Chevron).
+	+ add keys f12-f124 to pccon+keys (Tati Chevron).
+	+ add test/test_sgr.c program to exercise all combinations of sgr.
+
+20151107
+	+ modify tset's assignment to TERM in its output to reflect the name by
+	  which the terminal description is found, rather than the primary
+	  name.  That was an unnecessary part from the initial conversion of
+	  tset from termcap to terminfo.  The termcap program in 4.3BSD did
+	  this to avoid using the short 2-character name (report by Rich
+	  Burridge).
+	+ minor fix to configure script to ensure that rules for resulting.map
+	  are only generated when needed (cf: 20151101).
+	+ modify configure script to handle the case where tic-library is
+	  renamed, but the --with-debug option is used by itself without
+	  normal or shared libraries (prompted by comment in Debian #803482).
+
+20151101
+	+ amend change for pkg-config which allows build of pc-files when no
+	  valid pkg-config library directory was configured to suppress the
+	  actual install if it is not overridden to a valid directory at
+	  install time (cf: 20150822).
+	+ modify editing script which generates resulting.map to work with the
+	  clang configuration on recent FreeBSD, which gives an error on an
+	  empty "local" section.
+	+ fix a spurious "(Part)" message in test/ncurses.c b/B tests due
+	  to incorrect attribute-masking.
+
+20151024
+	+ modify MKexpanded.sh to update the expansion of a temporary filename
+	  to "expanded.c", for use in trace statements.
+	+ modify layout of b/B tests in test/ncurses.c to allow for additional
+	  annotation on the right margin; some terminals with partial support
+	  did not display well.
+	+ fix typo in curs_attr.3x (patch by Sven Joachim).
+	+ fix typo in INSTALL (patch by Tomas Cech).
+	+ improve configure check for setting WILDCARD_SYMS variable; on ppc64
+	  the variable is in the Data section rather than Text (patch by Michel
+	  Normand, Novell #946048).
+	+ using configure option "--without-fallbacks" incorrectly caused
+	  FALLBACK_LIST to be set to "no" (patch by Tomas Cech).
+	+ updated minitel entries to fix kel problem with emacs, and add
+	  minitel1b-nb (Alexandre Montaron).
+	+ reviewed/updated nsterm entry Terminal.app in OSX -TD
+	+ replace some dead URLs in comments with equivalents from the
+	  Internet Archive -TD
+	+ update config.guess, config.sub from
+		http://git.savannah.gnu.org/cgit/config.git
+
+20151017
+	+ modify ncurses/Makefile.in to sort keys.list in POSIX locale
+	  (Debian #801864, patch by Esa Peuha).
+	+ remove an early-return from _nc_do_color, which can interfere with
+	  data needed by bkgd when ncurses is configured with extended colors
+	  (patch by Denis Tikhomirov).
+	> fixes for OS/2 (patches by KO Myung-Hun)
+	+ use button instead of kbuf[0] in EMX-specific part of lib_mouse.c
+	+ support building with libtool on OS/2
+	+ use stdc++ on OS/2 kLIBC
+	+ clear cf_XOPEN_SOURCE on OS/2
+
+20151010
+	+ add configure check for openpty to test/configure script, for ditto.
+	+ minor fixes to test/view.c in investigating Debian #790847.
+	+ update autoconf patch to 2.52.20150926, incorporates a fix for Cdk.
+	+ add workaround for breakage of POSIX makefiles by recent binutils
+	  change.
+	+ improve check for working poll() by using posix_openpt() as a
+	  fallback in case there is no valid terminal on the standard input
+	  (prompted by discussion on bug-ncurses mailing list, Debian #676461).
+
+20150926
+	+ change makefile rule for removing resulting.map to distclean rather
+	  than clean.
+	+ add /lib/terminfo to terminfo-dirs in ".deb" test-package.
+	+ add note on portability of resizeterm and wresize to manual pages.
+
+20150919
+	+ clarify in resizeterm.3x how KEY_RESIZE is pushed onto the input
+	  stream.
+	+ clarify in curs_getch.3x that the keypad mode affects ability to
+	  read KEY_MOUSE codes, but does not affect KEY_RESIZE.
+	+ add overlooked build-fix needed with Cygwin for separate Ada95
+	  configure script, cf: 20150606 (report by Nicolas Boulenguez)
+
+20150912
+	+ fixes for configure/build using clang on OSX (prompted by report by
+	  William Gallafent).
+	  + do not redefine "inline" in ncurses_cfg.h; this was originally to
+	    solve a problem with gcc/g++, but is aggravated by clang's misuse
+	    of symbols to pretend it is gcc.
+	  + add braces to configure script to prevent unwanted add of
+	    "-lstdc++" to the CXXLIBS symbol.
+	  + improve/update test-program used for checking existence of stdc++
+	    library.
+	  + if $CXXLIBS is set, the linkage test uses that in addition to $LIBS
+
+20150905
+	+ add note in curs_addch.3x about line-drawing when it depends upon
+	  UTF-8.
+	+ add tic -q option for consistency with infocmp, use it to suppress
+	  all comments from the "tic -I" output.
+	+ modify infocmp -q option to suppress the "Reconstructed from"
+	  header.
+	+ add infocmp/tic -Q option, which allows one to dump the compiled
+	  form of the terminal entry, in hexadecimal or base64.
+
+20150822
+	+ sort options in usage message for infocmp, to make it simpler to
+	  see unused letters.
+	+ update usage message for tic, adding "-0" option.
+	+ documented differences in ESCDELAY versus AIX's implementation.
+	+ fix some compiler warnings from ports.
+	+ modify --with-pkg-config-libdir option to make it possible to install
+	  ".pc" files even if pkg-config is not found (adapted from patch by
+	  Joshua Root).
+
+20150815
+	+ disallow "no" as a possible value for "--with-shlib-version" option,
+	  overlooked in cleanup-changes for 20000708 (report by Tommy Alex).
+	+ update release notes in INSTALL.
+	+ regenerate llib-* files to help with review for release notes.
+
+20150810
+	+ workaround for Debian #65617, which was fixed in mawk's upstream
+	  releases in 2009 (report by Sven Joachim).  See
+	  	https://invisible-island.net/mawk/CHANGES.html#t20090727
+
+20150808 6.0 release for upload to ftp.gnu.org

+20150808
+	+ build-fix for Ada95 on older platforms without stdint.h
+	+ build-fix for Solaris, whose /bin/sh and /usr/bin/sed are non-POSIX.
+	+ update release announcement, summarizing more than 800 changes across
+	  more than 200 snapshots.
+	+ minor fixes to manpages, etc., to simplify linking from announcement
+	  page.
+
+20150725
+	+ updated llib-* files.
+	+ build-fixes for ncurses library "test_progs" rule.
+	+ use alternate workaround for gcc 5.x feature (adapted from patch by
+	  Mikhail Peselnik).
+	+ add status line to tmux via xterm+sl (patch by Nicholas Marriott).
+	+ fixes for st 0.5 from testing with tack -TD
+	+ review/improve several manual pages to break up wall-of-text:

+	+ correct an old logic error for %A and %O in tparm (report by "zreed").
+	+ improve documentation for signal handlers by adding section in the
+	  curs_initscr.3x page.
+	+ modify logic in make_keys.c to not assume anything about the size
+	  of strnames and strfnames variables, since those may be functions
+	  in the thread- or broken-linker configurations (problem found by
+	  Coverity).
+	+ modify test/configure script to check for pthreads configuration,
+	  e.g., ncursestw library.
+
+20150711
+	+ modify scripts to build/use test-packages for the pthreads
+	  configuration of ncurses6.
+	+ add references to ttytype and termcap symbols in demo_terminfo.c and
+	  demo_termcap.c to ensure that when building ncursest.map, etc., that
+	  the corresponding names such as _nc_ttytype are added to the list of
+	  versioned symbols (report by Werner Fink)
+	+ fix regression from 20150704 (report/patch by Werner Fink).
+
+20150704
+	+ fix a few problems reported by Coverity.
+	+ fix comparison against "/usr/include" in misc/gen-pkgconfig.in
+	  (report by Daiki Ueno, Debian #790548, cf:  20141213).
+
+20150627
+	+ modify configure script to remove deprecated ABI 5 symbols when
+	  building ABI 6.
+	+ add symbols _nc_Default_Field, _nc_Default_Form, _nc_has_mouse to
+	  map-files, but marked as deprecated so that they can easily be
+	  suppressed from ABI 6 builds (Debian #788610).
+	+ comment-out "screen.xterm" entry, and inherit screen.xterm-256color
+	  from xterm-new (report by Richard Birkett) -TD

+	  databases were found, as documented for setupterm.
+	+ add test_setupterm.c to demonstrate normal/error returns from the
+	  setupterm and restartterm functions.
+	+ amend cleanup change from 20110813 which removed redundant definition
+	  of ret_error, etc., from tinfo_driver.c, to account for the fact that
+	  it should return a bool rather than int (report/analysis by Johannes
+	  Schindelin).
+
+20150613
+	+ fix overflow warning for OSX with lib_baudrate.c (cf: 20010630).
+	+ modify script used to generate map/sym files to mark 5.9.20150530 as
+	  the last "5.9" version, and regenerated the files.  That makes the
+	  files not use ".current" for the post-5.9 symbols.  This also
+	  corrects the label for _nc_sigprocmask used in when weak symbols are
+	  configured for the ncursest/ncursestw libraries (prompted by
+	  discussion with Sven Joachim).
+	+ fix typo in NEWS (report by Sven Joachim).
+
+20150606 pre-release

+	  "--with-abi-version=5" option.
+	+ regenerate ada- and man-html documentation.
+	+ minor fixes to color- and util-manpages.
+	+ fix a regression in Ada95/gen/Makefile.in, to handle special case of
+	  Cygwin, which uses the broken-linker feature.
+	+ amend fix for CF_NCURSES_CONFIG used in test/configure to assume that
+	  ncurses package scripts work when present for cross-compiling, as the
+	  lessor of two evils (cf: 20150530).
+	+ add check in configure script to disallow conflicting options
+	  "--with-termlib" and "--enable-term-driver".
+	+ move defaults for "--disable-lp64" and "--with-versioned-syms" into
+	  CF_ABI_DEFAULTS macro.
+
+20150530
+	+ change private type for Event_Mask in Ada95 binding to work when

+	+ fix two problems with configure script macros (Debian #786436,
+	  cf: 20150425, cf: 20100529).
+
+20150523
+	+ add 'P' menu item to test/ncurses.c, to show pad in color.
+	+ improve discussion in curs_color.3x about color rendering (prompted
+	  by comment on Stack Overflow forum):
+	+ remove screen-bce.mlterm, since mlterm does not do "bce" -TD
+	+ add several screen.XXX entries to support the respective variations
+	  for 256 colors -TD
+	+ add putty+fnkeys* building-block entries -TD
+	+ add smkx/rmkx to capabilities analyzed with infocmp "-i" option.
+
+20150516
+	+ amend change to ".pc" files to only use the extra loader flags which
+	  may have rpath options (report by Sven Joachim, cf: 20150502).
+	+ change versioning for dpkg's in test-packages for Ada95 and
+	  ncurses-examples for consistency with Debian, to work with package
+	  updates.
+	+ regenerate html manpages.
+	+ clarify handling of carriage return in waddch manual page; it was
+	  discussed only in the portability section (prompted by comment on
+	  Stack Overflow forum):
+
+20150509
+	+ add test-packages for cross-compiling ncurses-examples using the
+	  MinGW test-packages.  These are only the Debian packages; RPM later.
+	+ cleanup format of debian/copyright files
+	+ add pc-files to the MinGW cross-compiling test-packages.
+	+ correct a couple of places in gen-pkgconfig.in to handle renaming of
+	  the tinfo library.
+
+20150502
+	+ modify the configure script to allow different default values
+	  for ABI 5 versus ABI 6.
+	+ add wgetch-events to test-packages.
+	+ add a note on how to build ncurses-examples to test/README.

+	  Debian #783486) -TD
+	+ remove unnecessary ';' from E3 capabilities -TD
+	+ add tmux entry, derived from screen (patch by Nicholas Marriott).
+	+ split-out recent change to nsterm-bce as nsterm-build326, and add
+	  nsterm-build342 to reflect changes with successive releases of OSX
+	  (discussion with Leonardo B Schenkel)
+	+ add xon, ich1, il1 to ibm3161 (patch by Stephen Powell, Debian
+	  #783806)
+	+ add sample "magic" file, to document ext-putwin.
+	+ modify gen-pkgconfig.in to add explicit -ltinfo, etc., to the
+	  generated ".pc" file when ld option "--as-needed" is used, or when
+	  ncurses and tinfo are installed without using rpath (prompted by
+	  discussion with Sylvain Bertrand).
+	+ modify test-package for ncurses6 to omit rpath feature when installed
+	  in /usr.
+	+ add OSX's "*.dSYM" to clean-rules in makefiles.
+	+ make extra-suffix work for OSX configuration, e.g., for shared
+	  libraries.
+	+ modify Ada95/configure script to work with pkg-config
+	+ move test-package for ncurses6 to /usr, since filename-conflicts have
+	  been eliminated.
+	+ corrected build rules for Ada95/gen/generate; it does not depend on
+	  the ncurses library aside from headers.
+	+ reviewed man pages, fixed a few other spelling errors.
+	+ fix a typo in curs_util.3x (Sven Joachim).
+	+ use extra-suffix in some overlooked shared library dependencies
+	  found by 20150425 changes for test-packages.

+	+ in-progress changes to modify test-packages to use ncursesw6 rather
+	  than ncursesw, with updated configure scripts.
+	+ modify CF_NCURSES_CONFIG in Ada95- and test-configure scripts to
+	  check for ".pc" files via pkg-config, but add a linkage check since
+	  frequently pkg-config configurations are broken.
+	+ modify misc/gen-pkgconfig.in to include EXTRA_LDFLAGS, e.g., for the
+	  rpath option.
+	+ add 'dim' capability to screen entry (report by Leonardo B Schenkel)
+	+ add several key definitions to nsterm-bce to match preconfigured
+	  keys, e.g., with OSX 10.9 and 10.10 (report by Leonardo B Schenkel)

+	+ fix bug in lib_tracebits.c introduced in const-fixes (cf: 20150404).
+
+20150418
+	+ avoid a blank line in output from tabs program by ending it with
+	  a carriage return as done in FreeBSD (patch by James Clarke).
+	+ build-fix for the "--enable-ext-putwin" feature when not using
+	  wide characters (report by Werner Fink).
+	+ modify autoconf macros to use scripting improvement from xterm.
+	+ add -brtl option to compiler options on AIX 5-7, needed to link
+	  with the shared libraries.
+	+ add --with-extra-suffix option to help with installing nonconflicting
+	  ncurses6 packages, e.g., avoiding header- and library-conflicts.
+	  NOTE: as a side-effect, this renames
+		  adacurses-config to adacurses5-config and
+		  adacursesw-config to adacursesw5-config
+	+ modify debian/rules test package to suffix programs with "6".
+	+ clarify in curs_inopts.3x that window-specific settings do not
+	  inherit into new windows.
+
+20150404
+	+ improve description of start_color() in the manual.
+	+ modify several files in ncurses- and progs-directories to allow
+	  const data used in internal tables to be put by the linker into the
+	  readonly text segment.
+
+20150329
+	+ correct cut/paste error for "--enable-ext-putwin" that made it the
+	  same as "--enable-ext-colors" (report by Roumen Petrov)
+
+20150328
+	+ add "-f" option to test/savescreen.c to help with testing/debugging
+	  the extended putwin/getwin.
+	+ add logic for writing/reading combining characters in the extended
+	  putwin/getwin.
+	+ add "--enable-ext-putwin" configure option to turn on the extended
+	  putwin/getwin.
+
+20150321
+	+ in-progress changes to provide an extended version of putwin and
+	  getwin which will be capable of reading screen-dumps between the
+	  wide/normal ncurses configurations.  These are text files, except
+	  for a magic code at the beginning:
+	  0       string          \210\210        Screen-dump (ncurses)
+
+20150307
+	+ document limitations of getwin in manual page (prompted by discussion
+	  with John S Urban).
+	+ extend test/savescreen.c to demonstrate that color pair values
+	  and graphic characters can be restored using getwin.
+
+20150228
+	+ modify win_driver.c to eliminate the constructor, to make it more
+	  usable in an application which may/may not need the console window
+	  (report by Grady Martin).
+
+20150221
+	+ capture define's related to -D_XOPEN_SOURCE from the configure check
+	  and add those to the *-config and *.pc files, to simplify use for
+	  the wide-character libraries.

+	  directory.
+	+ correct sense of "--disable-lib-suffixes" configure option (report
+	  by Nicolas Boos, cf: 20140426).
+
+20150214
+	+ regenerate html manpages using improved man2html from work on xterm.
+	+ regenerated ".map" and ".sym" files using improved script, accounting
+	  for the "--enable-weak-symbols" configure option (report by Werner
+	  Fink).
+
+20150131

+	  the combinations of configure options used at each stage.
+
+20150124
+	+ add configure check to determine if "local: _*;" can be used in the
+	  ".map" files to selectively omit symbols beginning with "_".  On at
+	  least recent FreeBSD, the wildcard applies to all "_" symbols.
+	+ remove obsolete/conflicting rule for ncurses.map from
+	  ncurses/Makefile.in (cf:  20130706).
+
+20150117
+	+ improve description in INSTALL of the --with-versioned-syms option.
+	+ add combination of --with-hashed-db and --with-ticlib to
+	  configurations for ".map" files (report by Werner Fink).

+	+ improve configure checks for pkg-config, addressing a variant found
+	  with FreeBSD ports.
+	+ modify win_driver.c to provide characters for special keys, like
+	  ansi.sys, when keypad mode is off, rather than returning nothing at
+	  all (discussion with Eli Zaretskii).
+	+ add "broken_linker" and "hashed-db" configure options to combinations
+	  use for generating the ".map" and ".sym" files.
+	+ avoid using "ld" directly when creating shared library, to simplify
+	  cross-compiles.  Also drop "-Bsharable" option from shared-library
+	  rules for FreeBSD and DragonFly (FreeBSD #196592).
+	+ fix a memory leak in form library Free_RegularExpression_Type()
+	  (report by Pavel Balaev).
+
+20150103
+	+ modify_nc_flush() to retry if interrupted (patch by Stian Skjelstad).
+	+ change map files to make _nc_freeall a global, since it may be used
+	  via the Ada95 binding when checking for memory leaks.
+	+ improve sed script used in 20141220 to account for wide-, threaded-
+	  variations in ABI 6.
+
+20141227
+	+ regenerate ".map" files, using step overlooked in 20141213 to use
+	  the same patch-dates across each file to match ncurses.map (report by
+	  Sven Joachim).
+
+20141221
+	+ fix an incorrect variable assignment in 20141220 changes (report by
+	  Sven Joachim).
+
+20141220
+	+ updated Ada95/configure with macro changes from 20141213
+	+ tie configure options --with-abi-version and --with-versioned-syms

+	+ replace obsolete/nonworking link to man2html with current one,
+	  regenerate html-manpages.
+
+20141213
+	+ modify misc/gen-pkgconfig.in to add -I option for include-directory
+	  when using both --prefix and --disable-overwrite (report by Misty
+	  De Meo).
+	+ add configure option --with-pc-suffix to allow minor renaming of
+	  ".pc" files and the corresponding library.  Use this in the test
+	  package for ncurses6.
+	+ modify configure script so that if pkg-config is not installed, it
+	  is still possible to install ".pc" files (report by Misty De Meo).
+	+ updated ".sym" files, removing symbols which are marked as "local"
+	  in the corresponding ".map" files.
+	+ updated ".map" files to reflect move of comp_captab and comp_hash
+	  from tic-library to tinfo-library in 20090711 (report by Sven
+	  Joachim).
+
+20141206
+	+ updated ".map" files so that each symbol that may be shared across
+	  the different library configurations has the same label.  Some
+	  review is needed to ensure these are really compatible.
+	+ modify MKlib_gen.sh to work around change in development version of
+	  gcc introduced here:
+		  https://gcc.gnu.org/ml/gcc-patches/2014-06/msg02185.html
+		  https://gcc.gnu.org/ml/gcc-patches/2014-07/msg00236.html
+	  (reports by Marcus Shawcroft, Maohui Lei).
+	+ improved configure macro CF_SUBDIR_PATH, from lynx changes.
+
+20141129
+	+ improved ".map" files by generating them with a script that builds
+	  ncurses with several related configurations and merges the results.
+	  A further refinement is planned, to make the tic- and tinfo-library
+	  symbols use the same versions across each of the four configurations
+	  which are represented (reports by Sven Joachim, Werner Fink).
+
+20141115
+	+ improve description of limits for color values and color pairs in
+	  curs_color.3x (prompted by patch by Tim van der Molen).
+	+ add VERSION file, using first field in that to record the ABI version
+	  used for configure --with-libtool --disable-libtool-version
+	+ add configure options for applying the ".map" and ".sym" files to
+	  the ncurses, form, menu and panel libraries.
+	+ add ".map" and ".sym" files to show exported symbols, e.g., for
+	  symbol-versioning.
+
+20141101
+	+ improve strict compiler-warnings by adding a cast in TRACE_RETURN
+	  and making a new TRACE_RETURN1 macro for cases where the cast does
+	  not apply.
+
+20141025
+	+ in-progress changes to integrate the win32 console driver with the
+	  msys2 configuration.
+
+20141018

+	  the vt100-compatibility issues were improved -TD
+	+ improve infocmp conversion of extended capabilities to termcap by
+	  correcting the limit check against parametrized[], as well as filling
+	  in a check if the string happens to have parameters, e.g., "xm"
+	  in recent changes.
+	+ add check for zero/negative dimensions for resizeterm and resize_term
+	  (report by Mike Gran).
+
+20141011
+	+ add experimental support for xterm's 1005 mouse mode, to use in a
+	  demonstration of its limitations.
+	+ add experimental support for "%u" format to terminfo.
+	+ modify test/ncurses.c to also show position reports in 'a' test.
+	+ minor formatting fixes to _nc_trace_mmask_t, make this function
+	  exported to help with debugging mouse changes.
+	+ improve behavior of wheel-mice for xterm protocol, noting that there
+	  are only button-presses for buttons "4" and "5", so there is no need
+	  to wait to combine events into double-clicks (report/analysis by
+	  Greg Field).
+	+ provide examples xterm-1005 and xterm-1006 terminfo entries -TD
+	+ implement decoder for xterm SGR 1006 mouse mode.
+
+20140927
+	+ implement curs_set in win_driver.c
+	+ implement flash in win_driver.c
+	+ fix an infinite loop in win_driver.c if the command-window loses
+	  focus.
+	+ improve the non-buffered mode, i.e., NCURSES_CONSOLE2, of
+	  win_driver.c by temporarily changing the buffer-size to match the
+	  window-size to eliminate the scrollback.  Also enforce a minimum
+	  screen-size of 24x80 in the non-buffered mode.
+	+ modify generated misc/Makefile to suppress install.data from the
+	  dependencies if the --disable-db-install option is used, compensating
+	  for the top-level makefile changes used to add ncurses*-config in the
+	  20140920 changes (report by Steven Honeyman).
+
+20140920
+	+ add ncurses*-config to bin-directory of sample package-scripts.
+	+ add check to ensure that getopt is available; this is a problem in
+	  some older cross-compiler environments.
+	+ expanded on the description of --disable-overwrite in INSTALL
+	  (prompted by reports by Joakim Tjernlund, Thomas Klausner).
+	  See Gentoo #522586 and NetBSD #49200 for examples.
+	  which relates to the clarified guidelines.
+	+ remove special logic from CF_INCLUDE_DIRS which adds the directory
+	  for the --includedir from the build (report by Joakim Tjernlund).
+	+ add case for Unixware to CF_XOPEN_SOURCE, from lynx changes.

+	+ merge redundant SEE-ALSO sections in form and menu manpages.
+
+20140809
+	+ modify declarations for user-data pointers in C++ binding to use
+	  reinterpret_cast to facilitate converting typed pointers to void*
+	  in user's application (patch by Adam Jiang).
+	+ regenerated html manpages.
+	+ add note regarding cause and effect for TERM in ncurses manpage,
+	  having noted clueless verbiage in Terminal.app's "help" file
+	  which reverses cause/effect.
+	+ remove special fallback definition for NCURSES_ATTR_T, since macros
+	  have resolved type-mismatches using casts (cf: 970412).
+	+ fixes for win_driver.c:
+	  + handle repainting on endwin/refresh combination.
+	  + implement beep().
+	  + minor cleanup.

+	+ fix most compiler warnings for Cygwin ncurses-examples.
+	+ restore "redundant" -I options in test/Makefile.in, since they are

+	  (cf: 20140726).
+
+20140726
+	+ eliminate some redundant -I options used for building libraries, and
+	  ensure that ${srcdir} is added to the include-options (prompted by
+	  discussion with Paul Gilmartin).
+	+ modify configure script to work with Minix3.2

+	+ when c_varargs_to_ada.c includes its header, use double quotes
+	  instead of <>.
+	+ samples/ncurses2-util.adb:  removed unused with clause.  The warning
+	  was removed by an obsolete pragma.
+	+ replaced Unreferenced pragmas with Warnings (Off).  The latter,
+	  available with older GNATs, needs no configure test.  This also
+	  replaces 3 untested Unreferenced pragmas.
+	+ simplified To_C usage in trace handling.  Using two parameters allows
+	  some basic formatting, and avoids a warning about security with some

+	  which introduces more than one gratuitous incompatibility.
+
+20140503
+	+ add vt520ansi terminfo entry (patch by Mike Gran)
+	+ further improve MinGW support for the scenario where there is an
+	  ANSI-escapes handler such as ansicon running in the console window
+	  (patch by Juergen Pfeifer).

+	  + use NC_ISATTY() macro for isatty() in library
+	  + add _nc_mingw_isatty() and related functions to windows-driver
+	  + rename terminal driver entrypoints to simplify grep's
+	+ remove a check in the sp-funcs flavor of newterm() which allowed only
+	  the first call to newterm() to succeed (report by Thomas Beierlein,
+	  cf: 20090927).
+

+	+ update config.guess, config.sub from
+		http://git.savannah.gnu.org/cgit/config.git
+
+20140412
+	+ modify configure script:
+	  + drop the -no-gcc option from Intel compiler, from lynx changes.
+	  + extend the --with-hashed-db configure option to simplify building
+	    with different versions of Berkeley database using FreeBSD ports.
+	+ improve initialization for MinGW port (Juergen Pfeifer):
+	  + enforce Windows-style path-separator if cross-compiling,
+	  + add a driver-name method to each of the drivers,
+	  + allow the Windows driver name to match "unknown", ignoring case,
+	  + lengthen the built-in name for the Windows console driver to
+	    "#win32console", and
+	  + move the comparison of driver-names allowing abbreviation, e.g.,
+	    to "#win32con" into the Windows console driver.
+
+20140329
+	+ add check in tic for mismatch between ccc and initp/initc
+	+ cancel ccc in putty-256color and konsole-256color for consistency
+	  with the cancelled initc capability (patch by Sven Zuhlsdorf).
+	+ add xterm+256setaf building block for various terminals which only
+	  get the 256-color feature half-implemented -TD
+	+ updated "st" entry (leaving the 0.1.1 version as "simpleterm") to
+	  0.4.1 -TD
+
+20140323

+
+20140322
+	+ use types from <stdint.h> in sample build-scripts for chtype, etc.

+	  using --with-chtype and related options to be defined in <stdint.h>
+	+ add terminology entry -TD
+	+ add mlterm3 entry, use that as "mlterm" -TD
+	+ inherit mlterm-256color from mlterm -TD
+
+20140315
+	+ modify _nc_New_TopRow_and_CurrentItem() to ensure that the menu's
+	  top-row is adjusted as needed to ensure that the current item is
+	  on the screen (patch by Johann Klammer).
+	+ add wgetdelay() to retrieve _delay member of WINDOW if it happens to
+	  be opaque, e.g., in the pthread configuration (prompted by patch by

+	+ add logic to win_driver.c to save/restore screen contents when not
+	  allocating a console-buffer (cf: 20140215).
+

+	+ clarify error-returns from newwin (report by Ruslan Nabioullin).
+
+20140222
+	+ fix some compiler warnings in win_driver.c

+	  console -TD
+
+20140215
+	+ in-progress changes to win_driver.c to implement output without
+	  allocating a console-buffer.  This uses a pre-existing environment
+	  variable NCGDB used by Juergen Pfeifer for debugging (prompted by
+	  discussion with Erwin Waterlander regarding Console2, which hangs
+	  when reading in an allocated console-buffer).
+	+ add -t option to gdc.c, and modify to accept "S" to step through the
+	  scrolling-stages.
+	+ regenerate NCURSES-Programming-HOWTO.html to fix some of the broken
+	  html emitted by docbook.
+
+20140209
+	+ modify CF_XOPEN_SOURCE macro to omit followup check to determine if
+	  _XOPEN_SOURCE can/should be defined.  g++ 4.7.2 built on Solaris 10
+	  has some header breakage due to its own predefinition of this symbol
+	  (report by Jean-Pierre Flori, Sage #15796).
+
+20140201
+	+ add/use symbol NCURSES_PAIRS_T like NCURSES_COLOR_T, to illustrate
+	  which "short" types are for color pairs and which are color values.
+	+ fix build for s390x, by correcting field bit offsets in generated
+	  representation clauses when int=32 long=64 and endian=big, or at
+	  least on s390x (patch by Nicolas Boulenguez).
+	+ minor cleanup change to test/form_driver_w.c (patch by Gaute Hope).
+
+20140125
+	+ remove unnecessary ifdef's in Ada95/gen/gen.c, which reportedly do
+	  not work as is with gcc 4.8 due to fixes using chtype cast made for
+	  new compiler warnings by gcc 4.8 in 20130824 (Debian #735753, patch
+	  by Nicolas Boulenguez).
+
+20140118
+	+ apply includesubdir variable which was introduced in 20130805 to
+	  gen-pkgconfig.in (Debian #735782).
+
+20131221

+	  manpages.  See
+	  ftp://ftp.invisible-island.net/ncurses/patches/man2html
+
+20131214
+	+ modify configure-script/ifdef's to allow OLD_TTY feature to be
+	  suppressed if the type of ospeed is configured using the option

+	  termcap-compatibility (adapted from suggestion by Christian
+	  Weisgerber).
+	+ correct a typo in _nc_baudrate() (patch by Christian Weisgerber,
+	  cf: 20061230).
+	+ fix a few -Wlogical-op warnings.
+	+ updated llib-l* files.
+
+20131207
+	+ add form_driver_w() entrypoint to wide-character forms library, as
+	  well as test program form_driver_w (adapted from patch by Gaute
+	  Hope).
+
+20131123
+	+ minor fix for CF_GCC_WARNINGS to special-case options which are not
+	  recognized by clang.
+
+20131116
+	+ add special case to configure script to move _XOPEN_SOURCE_EXTENDED
+	  definition from CPPFLAGS to CFLAGS if it happens to be needed for
+	  Solaris, because g++ errors with that definition (report by
+	  Jean-Pierre Flori, Sage #15268).
+	+ correct logic in infocmp's -i option which was intended to ignore
+	  strings which correspond to function-keys as candidates for piecing
+	  together initialization- or reset-strings.  The problem dates to
+	  1.9.7a, but was overlooked until changes in -Wlogical-op warnings for
+	  gcc 4.8 (report by David Binderman).
+	+ updated CF_GCC_WARNINGS to documented options for gcc 4.9.0, moving
+	  checks for -Wextra and -Wdeclaration-after-statement into the macro,
+	  and adding checks for -Wignored-qualifiers, -Wlogical-op and
+	  -Wvarargs
+	+ updated CF_CURSES_UNCTRL_H and CF_SHARED_OPTS macros from ongoing
+	  work on cdk.
+	+ update config.sub from

+	  (Debian #727119).
+	+ simplify pfkey expression in ansi.sys -TD
+
+20131027
+	+ correct/simplify ifdef's for cur_term versus broken-linker and
+	  reentrant options (report by Jean-Pierre Flori, cf: 20090530).
+	+ modify release/version combinations in test build-scripts to make
+	  them more consistent with other packages.
+
+20131019

+	  rpm macros.
+	+ add --disable-db-install configure option, to simplify building
+	  cross-compile support packages.
+	+ add mingw-ncurses.spec file, for testing cross-compiles.

+
+20130525
+	+ modify mvcur() to distinguish between internal use by the ncurses
+	  library, and external callers, preventing it from reading the content

+20130504
+	+ fixes for issues found by Coverity:

+	+ modify configure script to work around OS X's "libtool" program, to
+	  choose glibtool instead.  At the same time, chance the autoconf macro
+	  to look for a "tool" rather than a "prog", to help with potential use
+	  in cross-compiling.
+	+ separate the rpath usage for c++ library from demo program
+	  (Redhat #911540)
+	+ update/correct header-dependencies in c++ makefile (report by Werner

+	+ update manpage description of NCURSES_NO_SETBUF, explaining why it
+	  is obsolete.
+	+ add a check in waddch_nosync() to ensure that tab characters are

+20130216
+	+ modify test/testcurs.c to work with mouse for ncurses as it does for
+	  pdcurses.
+	+ modify test/knight.c to work with mouse for pdcurses as it does for
+	  ncurses.
+	+ modify internal recursion in wgetch() which handles cooked mode to
+	  check if the call to wgetnstr() returned an error.  This can happen
+	  when both nocbreak() and nodelay() are set, for instance (report by
+	  Nils Christopher Brause) (cf: 960418).
+	+ fixes for issues found by Coverity:
+	  + add a check for valid position in ClearToEOS()
+	  + fix in lib_twait.c when --enable-wgetch-events is used, pointer
+	    use after free.
+	  + improve a limit-check in make_hash.c
+	  + fix a memory leak in hashed_db.c
+
+20130209
+	+ modify test/configure script to make it simpler to override names
+	  of curses-related libraries, to help with linking with pdcurses in
+	  MinGW environment.
+	+ if the --with-terminfo-dirs configure option is not used, there is
+	  no corresponding compiled-in value for that.  Fill in "no default
+	  value" for that part of the manpage substitution.
+
+20130202
+	+ correct initialization in knight.c which let it occasionally make
+	  an incorrect move (cf: 20001028).
+	+ improve documentation of the terminfo/termcap search path.
+
+20130126
+	+ further fixes to mvcur to pass callback function (cf: 20130112),
+	  needed to make test/dots_mvcur work.
+	+ reduce calls to SetConsoleActiveScreenBuffer in win_driver.c, to
+	  help reduce flicker.
+	+ modify configure script to omit "+b" from linker options for very

+	  by Dennis Grevenstein).
+	+ restore memmove/strdup support for antique systems (request by
+	  Dennis Grevenstein).
+	+ change %l behavior in tparm to push the string length onto the stack
+	  rather than saving the formatted length into the output buffer
+	  (report by Roy Marples, cf: 980620).
+
+20130119
+	+ fixes for issues found by Coverity:
+	  + fix memory leak in safe_sprintf.c
+	  + add check for return-value in tty_update.c
+	  + correct initialization for -s option in test/view.c
+	  + add check for numeric overflow in lib_instr.c
+	  + improve error-checking in copywin
+	+ add advice in infocmp manpage for termcap users (Debian #698469).

+	  matching capability names.
+	+ modify name-comparison for tgetstr, etc., to accommodate legacy
+	  applications as well as to improve compatibility with BSD 4.2
+	  termcap implementations (Debian #698299) (cf: 980725).
+
+20130112
+	+ correct prototype in manpage for vid_puts.
+	+ drop ncurses/tty/tty_display.h, ncurses/tty/tty_input.h, since they
+	  are unused in the current driver model.
+	+ modify mvcur to use stdout except when called within the ncurses
+	  library.
+	+ modify vidattr and vid_attr to use stdout as documented in manpage.
+	+ amend changes made to buffering in 20120825 so that the low-level
+	  putp() call uses stdout rather than ncurses' internal buffering.
+	  The putp_sp() call does the same, for consistency (Redhat #892674).
+
+20130105
+	+ add "-s" option to test/view.c to allow it to start in single-step
+	  mode, reducing size of trace files when it is used for debugging
+	  MinGW changes.
+	+ revert part of 20121222 change to tinfo_driver.c
+	+ add experimental logic in win_driver.c to improve optimization of
+	  screen updates.  This does not yet work with double-width characters,
+	  so it is ifdef'd out for the moment (prompted by report by Erwin
+	  Waterlander regarding screen flicker).
+
+20121229
+	+ fix Coverity warnings regarding copying into fixed-size buffers.
+	+ add throw-declarations in the c++ binding per Coverity warning.

+	  cf: 20011208).
+	+ improve 20021221 workaround for broken acs, handling a case where

+	  wide-character which can be used.
+
+20121215
+	+ fix several warnings from clang 3.1 --analyze, includes correcting
+	  a null-pointer check in _nc_mvcur_resume.
+	+ correct display of double-width characters with MinGW port (report
+	  by Erwin Waterlander).
+	+ replace MinGW's wcrtomb(), fixing a problem with _nc_viscbuf
+	> fixes based on Coverity report:

+	+ remove dead code in progs/tset.c, test/linedata.h
+	+ add null-pointer checks in lib_tracemse.c, panel.priv.h, and some
+	  test-programs.
+
+20121208
+	+ modify test/knight.c to show the number of choices possible for
+	  each position in automove option, e.g., to allow user to follow
+	  Warnsdorff's rule to solve the puzzle.
+	+ modify test/hanoi.c to show the minimum number of moves possible for
+	  the given number of tiles (prompted by patch by Lucas Gioia).
+	> fixes based on Coverity report:
+	+ remove a few redundant checks.

+	+ initialize wbkgrndset() temporary variable when extended-colors are
+	  used.
+
+20121201
+	+ also replace MinGW's wctomb(), fixing a problem with setcchar().
+	+ modify test/view.c to load UTF-8 when built with MinGW by using
+	  regular win32 API because the MinGW functions mblen() and mbtowc()
+	  do not work.
+
+20121124
+	+ correct order of color initialization versus display in some of the
+	  test-programs, e.g., test_addstr.c
+	> fixes based on Coverity report:
+	+ delete windows on exit from some of the test-programs.

+	  test/insdelln.c, test/newdemo.c on error-return.
+
+20121110
+	+ modify configure macro CF_INCLUDE_DIRS to put $CPPFLAGS after the
+	  local -I include options in case someone has set conflicting -I
+	  options in $CPPFLAGS (prompted by patch for ncurses/Makefile.in by
+	  Vassili Courzakis).
+	+ modify the ncurses*-config scripts to eliminate relative paths from
+	  the RPATH_LIST variable, e.g., "../lib" as used in installing shared
+	  libraries or executables.
+
+20121102
+	+ realign these related pages:
+	    curs_add_wchstr.3x
+	    curs_addchstr.3x
+	    curs_addstr.3x
+	    curs_addwstr.3x
+	  and fix a long-ago error in curs_addstr.3x which said that a -1
+	  length parameter would only write as much as fit onto one line
+	  (report by Reuben Thomas).
+	+ remove obsolete fallback _nc_memmove() for memmove()/bcopy().
+	+ remove obsolete fallback _nc_strdup() for strdup().
+	+ cancel any debug-rpm in package/ncurses.spec
+	+ reviewed vte-2012, reverted most of the change since it was incorrect
+	  based on testing with tack -TD

+	  starting with version 0.20 in 2009 -TD
+
+20121026
+	+ improve malloc/realloc checking (prompted by discussion in Redhat
+	  #866989).
+	+ add ncurses test-program as "ncurses6" to the rpm- and dpkg-scripts.
+	+ updated configure macros CF_GCC_VERSION and CF_WITH_PATHLIST.  The
+	  first corrects pattern used for Mac OS X's customization of gcc.
+
+20121017
+	+ fix change to _nc_scroll_optimize(), which incorrectly freed memory
+	  (Redhat #866989).
+
+20121013
+	+ add vte-2012, gnome-2012, making these the defaults for vte/gnome
+	  (patch by Christian Persch).
+
+20121006
+	+ improve CF_GCC_VERSION to work around Debian's customization of gcc
+	  --version message.
+	+ improve configure macros as done in byacc:
+	  + drop 2.13 compatibility; use 2.52.xxxx version only since EMX port
+	    has used that for a while.
+	  + add 3rd parameter to AC_DEFINE's to allow autoheader to run, i.e.,
+	    for experimental use.

+	+ improve comparisons in configure.in for unset shell variables.
+
+20120826
+	+ increase size of ncurses' output-buffer, in case of very small
+	  initial screen-sizes.
+	+ fix evaluation of TERMINFO and TERMINFO_DIRS default values as needed
+	  after changes to use --datarootdir (reports by Gabriele Balducci,
+	  Roumen Petrov).
+
+20120825
+	+ change output buffering scheme, using buffer maintained by ncurses
+	  rather than stdio, to avoid problems with SIGTSTP handling (report
+	  by Brian Bloniarz).
+
+20120811
+	+ update autoconf patch to 2.52.20120811, adding --datarootdir
+	  (prompted by discussion with Erwin Waterlander).
+	+ improve description of --enable-reentrant option in README and the

+	  Sven Joachim, cf:  20120317).
+	+ modify followup check for pkg-config's library directory in the
+	  --enable-pc-files option to validate syntax (report by Sven Joachim,
+	  cf: 20110716).
+
+20120728
+	+ correct path for ncurses_mingw.h in include/headers, in case build
+	  is done outside source-tree (patch by Roumen Petrov).
+	+ modify some older xterm entries to align with xterm source -TD
+	+ separate "xterm-old" alias from "xterm-r6" -TD
+	+ add E3 extended capability to xterm-basic and putty -TD

+
+20120714
+	+ add use_tioctl() function (adapted from patch by Werner Fink,
+	  Novell #769788):
+
+20120707
+	+ add ncurses_mingw.h to installed headers (prompted by patch by
+	  Juergen Pfeifer).
+	+ clarify return-codes from wgetch() in response to SIGWINCH (prompted
+	  by Novell #769788).
+	+ modify resizeterm() to always push a KEY_RESIZE onto the fifo, even
+	  if screensize is unchanged.  Modify _nc_update_screensize() to push a
+	  KEY_RESIZE if there was a SIGWINCH, even if it does not call
+	  resizeterm().  These changes eliminate the case where a SIGWINCH is
+	  received, but ERR returned from wgetch or wgetnstr because the screen
+	  dimensions did not change (Novell #769788).
+
+20120630
+	+ add --enable-interop to sample package scripts (suggested by Juergen
+	  Pfeifer).
+	+ update CF_PATH_SYNTAX macro, from mawk changes.
+	+ modify mk-0th.awk to allow for generating llib-ltic, etc., though
+	  some work is needed on cproto to work with lib_gen.c to update
+	  llib-lncurses.
+	+ remove redundant getenv() cal in database-iterator leftover from
+	  cleanup in 20120622 changes (report by Sven Joachim).

+	  warnings about unused command-line parameters when compiler warnings
+	  are enabled.
+	+ improve behavior when updating terminfo entries which are hardlinked
+	  by allowing for the possibility that an alias has been repurposed to
+	  a new primary name.
+	+ fix some strict compiler warnings based on package scripts.
+	+ further fixes for configure check for working poll (Debian #676461).
+
+20120608
+	+ fix an uninitialized variable in -c/-n logic for infocmp changes
+	  (cf: 20120526).
+	+ corrected fix for building c++ binding with clang 3.0 (report/patch
+	  by Richard Yao, Gentoo #417613, cf: 20110409)
+	+ correct configure check for working poll, fixing the case where stdin
+	  is redirected, e.g., in rpm/dpkg builds (Debian #676461).
+	+ add rpm- and dpkg-scripts, to test those build-environments.
+	  The resulting packages are used only for testing.
+
+20120602
+	+ add kdch1 aka "Remove" to vt220 and vt220-8 entries -TD
+	+ add kdch1, etc., to qvt108 -TD
+	+ add dl1/il1 to some entries based on dl/il values -TD

+	  controls, and insert/delete-char keys
+	+ correct no-leaks logic in infocmp when doing comparisons, fixing

+	  entries loaded from the last-but-one of files specified on the
+	  command-line.
+	+ add kdch1 to wsvt25 entry from NetBSD CVS (reported by David Lord,
+	  analysis by Martin Husemann).
+	+ add cnorm/civis to wsvt25 entry from NetBSD CVS (report/analysis by
+	  Onno van der Linden).
+
+20120526
+	+ extend -c and -n options of infocmp to allow comparing more than two
+	  entries.
+	+ correct check in infocmp for number of terminal names when more than
+	  two are given.
+	+ correct typo in curs_threads.3x (report by Yanhui Shen on
+	  freebsd-hackers mailing list).
+
+20120512
+	+ corrected 'op' for bterm (report by Samuel Thibault) -TD
+	+ modify test/background.c to demonstrate a background character
+	  holding a colored ACS_HLINE.  The behavior differs from SVr4 due to
+	  the thick- and double-line extension (cf: 20091003).
+	+ modify handling of acs characters in PutAttrChar to avoid mapping an
+	  unmapped character to a space with A_ALTCHARSET set.
+	+ rewrite vt520 entry based on vt420 -TD
+
+20120505
+	+ remove p6 (bold) from opus3n1+ for consistency -TD

+	+ make sgr for d210 agree with other caps -TD
+	+ make sgr for d470c, d470c-7b agree with other caps -TD
+	+ remove redundant AC_DEFINE for NDEBUG versus Makefile definition.
+	+ fix a back-link in _nc_delink_entry(), which is needed if ncurses is
+	  configured with --enable-termcap and --disable-getcap.
+
+20120428
+	+ fix some inconsistencies between vt320/vt420, e.g., cnorm/civis -TD
+	+ add eslok flag to dec+sl -TD
+	+ dec+sl applies to vt320 and up -TD
+	+ drop wsl width from xterm+sl -TD

+20120421
+	+ improve cleanup of temporary files in tic using atexit().
+	+ add msgr to vt420, similar DEC vtXXX entries -TD
+	+ add several missing vt420 capabilities from vt220 -TD
+	+ factor out ansi+pp from several entries -TD
+	+ change xterm+sl and xterm+sl-twm to include only the status-line
+	  capabilities and not "use=xterm", making them more generally useful
+	  as building-blocks -TD
+	+ add dec+sl building block, as example -TD
+
+20120414
+	+ add XT to some terminfo entries to improve usefulness for other
+	  applications than screen, which would like to pretend that xterm's
+	  title is a status-line.  -TD
+	+ change use-clauses in ansi-mtabs, hp2626, and hp2622 based on review
+	  of ordering and overrides -TD
+	+ add consistency check in tic for screen's "XT" capability.
+	+ add section in terminfo.src summarizing the user-defined capabilities
+	  used in that file -TD
+
+20120407
+	+ fix an inconsistency between tic/infocmp "-x" option; tic omits all
+	  non-standard capabilities, while infocmp was ignoring only the user
+	  definable capabilities.
+	+ improve special case in tic parsing of description to allow it to be
+	  followed by terminfo capabilities.  Previously the description had to
+	  be the last field on an input line to allow tic to distinguish
+	  between termcap and terminfo format while still allowing commas to be
+	  embedded in the description.
+	+ correct variable name in gen_edit.sh which broke configurability of
+	  the --with-xterm-kbs option.
+	+ revert 2011-07-16 change to "linux" alias, return to "linux2.2" -TD
+	+ further amend 20110910 change, providing for configure-script

+
+20120331
+	+ update Ada95/configure to use CF_DISABLE_ECHO (cf: 20120317).
+	+ correct order of use-clauses in st-256color -TD
+	+ modify configure script to look for gnatgcc if the Ada95 binding
+	  is built, in preference to the default gcc/cc (suggested by
+	  Nicolas Boulenguez).
+	+ modify configure script to ensure that the same -On option used for
+	  the C compiler in CFLAGS is used for ADAFLAGS rather than simply
+	  using "-O3" (suggested by Nicolas Boulenguez)
+
+20120324
+	+ amend an old fix so that next_char() exits properly for empty files,
+	  e.g., from reading /dev/null (cf: 20080804).
+	+ modify tic so that it can read from the standard input, or from
+	  a character device.  Because tic uses seek's, this requires writing
+	  the data to a temporary file first (prompted by remark by Sven
+	  Joachim) (cf: 20000923).
+
+20120317
+	+ correct a check made in lib_napms.c, so that terminfo applications
+	  can again use napms() (cf: 20110604).
+	+ add a note in tic.h regarding required casts for ABSENT_BOOLEAN
+	  (cf: 20040327).
+	+ correct scripting for --disable-echo option in test/configure.
+	+ amend check for missing c++ compiler to work when no error is
+	  reported, and no variables set (cf: 20021206).
+	+ add/use configure macro CF_DISABLE_ECHO.
+
+20120310
+	+ fix some strict compiler warnings for abi6 and 64-bits.
+	+ use begin_va_copy/end_va_copy macros in lib_printw.c (cf: 20120303).
+	+ improve a limit-check in infocmp.c (Werner Fink):
+
+20120303
+	+ minor tidying of terminfo.tail, clarify reason for limitation
+	  regarding mapping of \0 to \200
+	+ minor improvement to _nc_copy_termtype(), using memcpy to replace
+	  loops.
+	+ fix no-leaks checking in test/demo_termcap.c to account for multiple
+	  calls to setupterm().
+	+ modified the libgpm change to show previous load as a problem in the
+	  debug-trace.
+	> merge some patches from OpenSUSE rpm (Werner Fink):
+	+ ncurses-5.7-printw.dif, fixes for varargs handling in lib_printw.c
+	+ ncurses-5.7-gpm.dif, do not dlopen libgpm if already loaded by
+	  runtime linker
+	+ ncurses-5.6-fallback.dif, do not free arrays and strings from static
+	  fallback entries
+
+20120228
+	+ fix breakage in tic/infocmp from 20120225 (report by Werner Fink).
+
+20120225
+	+ modify configure script to allow creating dll's for MinGW when
+	  cross-compiling.
+	+ add --enable-string-hacks option to control whether strlcat and
+	  strlcpy may be used.  The same issue applies to OpenBSD's warnings
+	  about snprintf, noting that this function is weakly standardized.
+	+ add configure checks for strlcat, strlcpy and snprintf, to help
+	  reduce bogus warnings with OpenBSD builds.
+	+ build-fix for OpenBSD 4.9 to supply consistent intptr_t declaration
+	  (cf:20111231)
+	+ update config.guess, config.sub
+
+20120218
+	+ correct CF_ETIP_DEFINES configure macro, making it exit properly on
+	  the first success (patch by Pierre Labastie).
+	+ improve configure macro CF_MKSTEMP by moving existence-check for
+	  mkstemp out of the AC_TRY_RUN, to help with cross-compiles.
+	+ improve configure macro CF_FUNC_POLL from luit changes to detect
+	  broken implementations, e.g., with Mac OS X.
+	+ add configure option --with-tparm-arg
+	+ build-fix for MinGW cross-compiling, so that make_hash does not
+	  depend on TTY definition (cf: 20111008).

+	  better diagnostics.
+
+20120128

+	+ amend fix intended to separate fixups for acsc to allow "tic -cv" to
+	  give verbose warnings (cf:  20110730).
+	+ modify misc/gen-edit.sh to make the location of the tabset directory
+	  consistent with misc/Makefile.in, i.e., using ${datadir}/tabset
+	  (Debian #653435, patch by Sven Joachim).
+
+20120121
+	+ add --with-lib-prefix option to allow configuring for old/new flavors
+	  of OS/2 EMX.
+	+ modify check for gnat version to allow for year, as used in FreeBSD
+	  port.
+	+ modify check_existence() in db_iterator.c to simply check if the
+	  path is a directory or file, according to the need.  Checking for
+	  directory size also gives no usable result with OS/2 (cf: 20120107).
+	+ support OS/2 kLIBC (patch by KO Myung-Hun).
+
+20120114
+	+ several improvements to test/movewindow.c (prompted by discussion on
+	  Linux Mint forum):
+	  + modify movement commands to make them continuous
+	  + rewrote the test for mvderwin
+	  + rewrote the test for recursive mvwin
+	+ split-out reusable CF_WITH_NCURSES_ETC macro in test/configure.in
+	+ updated configure macro CF_XOPEN_SOURCE, build-fixes for Mac OS X
+	  and OpenBSD.
+	+ regenerated html manpages.
+
+20120107
+	+ various improvements for MinGW (Juergen Pfeifer):
+	  + modify stat() calls to ignore the st_size member
+	  + drop mk-dlls.sh script.
+	  + change recommended regular expression library.
+	  + modify rain.c to allow for threaded configuration.
+	  + modify tset.c to allow for case when size-change logic is not used.
+
+20111231
+	+ modify toe's report when -a and -s options are combined, to add
+	  a column showing which entries belong to a given database.
+	+ add -s option to toe, to sort its output.
+	+ modify progs/toe.c, simplifying use of db-iterator results to use
+	  caching improvements from 20111001 and 20111126.
+	+ correct generation of pc-files when ticlib or termlib options are
+	  given to rename the corresponding tic- or tinfo-libraries (report
+	  by Sven Joachim).
+
+20111224
+	+ document a portability issue with tput, i.e., that scripts which work
+	  with ncurses may fail in other implementations that do no parameter
+	  analysis.
+	+ add putty-sco entry -TD
+
+20111217
+	+ review/fix places in manpages where --program-prefix configure option
+	  was not being used.
+	+ add -D option to infocmp, to show the database locations that it
+	  could use.
+	+ fix build for the special case where term-driver, ticlib and termlib
+	  are all enabled.  The terminal driver depends on a few features in
+	  the base ncurses library, so tic's dependencies include both ncurses
+	  and termlib.
+	+ fix build work for term-driver when --enable-wgetch-events option is
+	  enabled.
+	+ use <stdint.h> types to fix some questionable casts to void*.
+
+20111210
+	+ modify configure script to check if thread library provides
+	  pthread_mutexattr_settype(), e.g., not provided by Solaris 2.6
+	+ modify configure script to suppress check to define _XOPEN_SOURCE
+	  for IRIX64, since its header files have a conflict versus
+	  _SGI_SOURCE.
+	+ modify configure script to add ".pc" files for tic- and
+	  tinfo-libraries, which were omitted in recent change (cf: 20111126).
+	+ fix inconsistent checks on $PKG_CONFIG variable in configure script.
+
+20111203
+	+ modify configure-check for etip.h dependencies, supplying a temporary
+	  copy of ncurses_dll.h since it is a generated file (prompted by
+	  Debian #646977).
+	+ modify CF_CPP_PARAM_INIT "main" function to work with current C++.
+
+20111126
+	+ correct database iterator's check for duplicate entries
+	  (cf: 20111001).
+	+ modify database iterator to ignore $TERMCAP when it is not an
+	  absolute pathname.
+	+ add -D option to tic, to show the database locations that it could
+	  use.
+	+ improve description of database locations in tic manpage.
+	+ modify the configure script to generate a list of the ".pc" files to
+	  generate, rather than deriving the list from the libraries which have
+	  been built (patch by Mike Frysinger).
+	+ use AC_CHECK_TOOLS in preference to AC_PATH_PROGS when searching for
+	  ncurses*-config, e.g., in Ada95/configure and test/configure (adapted
+	  from patch by Mike Frysinger).
+
+20111119
+	+ remove obsolete/conflicting fallback definition for _POSIX_SOURCE
+	  from curses.priv.h, fixing a regression with IRIX64 and Tru64
+	  (cf: 20110416)
+	+ modify _nc_tic_dir() to ensure that its return-value is nonnull,
+	  i.e., the database iterator was not initialized.  This case is needed
+	  to when tic is translating to termcap, rather than loading the
+	  database (cf:  20111001).
+
+20111112
+	+ add pccon entries for OpenBSD console (Alexei Malinin).
+	+ build-fix for OpenBSD 4.9 with gcc 4.2.1, setting _XOPEN_SOURCE to
+	  600 to work around inconsistent ifdef'ing of wcstof between C and
+	  C++ header files.
+	+ modify capconvert script to accept more than exact match on "xterm",
+	  e.g., the "xterm-*" variants, to exclude from the conversion (patch
+	  by Robert Millan).
+	+ add -lc_r as alternative for -lpthread, allows build of threaded code
+	  in older FreeBSD machines.
+	+ build-fix for MirBSD, which fails when either _XOPEN_SOURCE or
+	  _POSIX_SOURCE are defined.
+	+ fix a typo misc/Makefile.in, used in uninstalling pc-files.
+
+20111030
+	+ modify make_db_path() to allow creating "terminfo.db" in the same
+	  directory as an existing "terminfo" directory.  This fixes a case
+	  where switching between hashed/filesystem databases would cause the
+	  new hashed database to be installed in the next best location -
+	  root's home directory.
+	+ add variable cf_cv_prog_gnat_correct to those passed to
+	  config.status, fixing a problem with Ada95 builds (cf: 20111022).
+	+ change feature test from _XPG5 to _XOPEN_SOURCE in two places, to
+	  accommodate broken implementations for _XPG6.
+	+ eliminate usage of NULL symbol from etip.h, to reduce header
+	  interdependencies.
+	+ add configure check to decide when to add _XOPEN_SOURCE define to
+	  compiler options, i.e., for Solaris 10 and later (cf: 20100403).
+	  This is a workaround for gcc 4.6, which fails to build the c++
+	  binding if that symbol is defined by the application, due to
+	  incorrectly combining the corresponding feature test macros
+	  (report by Peter Kruse).
+
+20111022
+	+ correct logic for discarding mouse events, retaining the partial
+	  events used to build up click, double-click, etc, until needed
+	  (cf: 20110917).
+	+ fix configure script to avoid creating unused Ada95 makefile when
+	  gnat does not work.
+	+ cleanup width-related gcc 3.4.3 warnings for 64-bit platform, for the
+	  internal functions of libncurses.  The external interface of courses
+	  uses bool, which still produces these warnings.
+
+20111015
+	+ improve description of --disable-tic-depends option to make it
+	  clear that it may be useful whether or not the --with-termlib
+	  option is also given (report by Sven Joachim).
+	+ amend termcap equivalent for set_pglen_inch to use the X/Open
+	  "YI" rather than the obsolete Solaris 2.5 "sL" (cf: 990109).
+	+ improve manpage for tgetent differences from termcap library.
+
+20111008
+	+ moved static data from db_iterator.c to lib_data.c
+	+ modify db_iterator.c for memory-leak checking, fix one leak.
+	+ modify misc/gen-pkgconfig.in to use Requires.private for the parts
+	  of ncurses rather than Requires, as well as Libs.private for the
+	  other library dependencies (prompted by Debian #644728).
+
+20111001
+	+ modify tic "-K" option to only set the strict-flag rather than force
+	  source-output.  That allows the same flag to control the parser for
+	  input and output of termcap source.
+	+ modify _nc_getent() to ignore backslash at the end of a comment line,
+	  making it consistent with ncurses' parser.
+	+ restore a special-case check for directory needed to make termcap
+	  text files load as if they were databases (cf: 20110924).
+	+ modify tic's resolution/collision checking to attempt to remove the
+	  conflicting alias from the second entry in the pair, which is
+	  normally following in the source file.  Also improved the warning
+	  message to make it simpler to see which alias is the problem.
+	+ improve performance of the database iterator by caching search-list.
+
+20110925
+	+ add a missing "else" in changes to _nc_read_tic_entry().
+
+20110924
+	+ modify _nc_read_tic_entry() so that hashed-database is checked before
+	  filesystem.
+	+ updated CF_CURSES_LIBS check in test/configure script.
+	+ modify configure script and makefiles to split TIC_ARGS and
+	  TINFO_ARGS into pieces corresponding to LDFLAGS and LIBS variables,
+	  to help separate searches for tic- and tinfo-libraries (patch by Nick
+	  Alcock aka "Nix").
+	+ build-fix for lib_mouse.c changes (cf: 20110917).
+
+20110917
+	+ fix compiler warning for clang 2.9
+	+ improve merging of mouse events (integrated patch by Damien
+	  Guibouret).
+	+ correct mask-check used in lib_mouse for wheel mouse buttons 4/5
+	  (patch by Damien Guibouret).
+
+20110910
+	+ modify misc/gen_edit.sh to select a "linux" entry which works with
+	  the current kernel rather than assuming it is always "linux3.0"
+	  (cf: 20110716).
+	+ revert a change to getmouse() which had the undesirable side-effect
+	  of suppressing button-release events (report by Damien Guibouret,
+	  cf: 20100102).
+	+ add xterm+kbs fragment from xterm #272 -TD
+	+ add configure option --with-pkg-config-libdir to provide control over
+	  the actual directory into which pc-files are installed, do not use
+	  the pkg-config environment variables (discussion with Frederic L W
+	  Meunier).
+	+ add link to mailing-list archive in announce.html.in, as done in
+	  FAQ (prompted by question by Andrius Bentkus).
+	+ improve manpage install by adjusting the "#include" examples to
+	  show the ncurses-subdirectory used when --disable-overwrite option
+	  is used.
+	+ install an alias for "curses" to the ncurses manpage, tied to the
+	  --with-curses-h configure option (suggested by Reuben Thomas).
+
+20110903
+	+ propagate error-returns from wresize, i.e., the internal
+	  increase_size and decrease_size functions through resize_term (report
+	  by Tim van der Molen, cf:  20020713).
+	+ fix typo in tset manpage (patch by Sven Joachim).
+
+20110820
+	+ add a check to ensure that termcap files which might have "^?" do
+	  not use the terminfo interpretation as "\177".
+	+ minor cleanup of X-terminal emulator section of terminfo.src -TD
+	+ add terminator entry -TD
+	+ add simpleterm entry -TD
+	+ improve wattr_get macros by ensuring that if the window pointer is
+	  null, then the attribute and color values returned will be zero
+	  (cf: 20110528).
+
+20110813
+	+ add substitution for $RPATH_LIST to misc/ncurses-config.in
+	+ improve performance of tic with hashed-database by caching the
+	  database connection, using atexit() to cleanup.
+	+ modify treatment of 2-character aliases at the beginning of termcap
+	  entries so they are not counted in use-resolution, since these are
+	  guaranteed to be unique.  Also ignore these aliases when reporting
+	  the primary name of the entry (cf: 20040501)
+	+ double-check gn (generic) flag in terminal descriptions to
+	  accommodate old/buggy termcap databases which misused that feature.
+	+ minor fixes to _nc_tgetent(), ensure buffer is initialized even on
+	  error-return.
+
+20110807
+	+ improve rpath fix from 20110730 by ensuring that the new $RPATH_LIST
+	  variable is defined in the makefiles which use it.
+	+ build-fix for DragonFlyBSD's pkgsrc in test/configure script.
+	+ build-fixes for NetBSD 5.1 with termcap support enabled.
+	+ corrected k9 in dg460-ansi, add other features based on manuals -TD
+	+ improve trimming of whitespace at the end of terminfo/termcap output
+	  from tic/infocmp.
+	+ when writing termcap source, ensure that colons in the description
+	  field are translated to a non-delimiter, i.e., "=".
+	+ add "-0" option to tic/infocmp, to make the termcap/terminfo source
+	  use a single line.
+	+ add a null-pointer check when handling the $CC variable.
+
+20110730
+	+ modify configure script and makefiles in c++ and progs to allow the
+	  directory used for rpath option to be overridden, e.g., to work
+	  around updates to the variables used by tic during an install.
+	+ add -K option to tic/infocmp, to provide stricter BSD-compatibility
+	  for termcap output.
+	+ add _nc_strict_bsd variable in tic library which controls the
+	  "strict" BSD termcap compatibility from 20110723, plus these
+	  features:
+	  + allow escapes such as "\8" and "\9" when reading termcap
+	  + disallow "\a", "\e", "\l", "\s" and "\:" escapes when reading
+	    termcap files, passing through "a", "e", etc.
+	  + expand "\:" as "\072" on output.
+	+ modify _nc_get_token() to reset the token's string value in case
+	  there is a string-typed token lacking the "=" marker.
+	+ fix a few memory leaks in _nc_tgetent.
+	+ fix a few places where reading from a termcap file could refer to
+	  freed memory.
+	+ add an overflow check when converting terminfo/termcap numeric
+	  values, since terminfo stores those in a short, and they must be
+	  positive.
+	+ correct internal variables used for translating to termcap "%>"
+	  feature, and translating from termcap %B to terminfo, needed by
+	  tctest (cf: 19991211).
+	+ amend a minor fix to acsc when loading a termcap file to separate it
+	  from warnings needed for tic (cf: 20040710)
+	+ modify logic in _nc_read_entry() and _nc_read_tic_entry() to allow
+	  a termcap file to be handled via TERMINFO_DIRS.
+	+ modify _nc_infotocap() to include non-mandatory padding when
+	  translating to termcap.
+	+ modify _nc_read_termcap_entry(), passing a flag in the case where
+	  getcap is used, to reduce interactive warning messages.
+
+20110723
+	+ add a check in start_color() to limit color-pairs to 256 when
+	  extended colors are not supported (patch by David Benjamin).
+	+ modify setcchar to omit no-longer-needed OR'ing of color pair in
+	  the SetAttr() macro (patch by David Benjamin).
+	+ add kich1 to sun terminfo entry (Yuri Pankov)
+	+ use bold rather than reverse for smso in sun-color terminfo entry
+	  (Yuri Pankov).
+	+ improve generation of termcap using tic/infocmp -C option, e.g.,
+	  to correspond with 4.2BSD (prompted by discussion with Yuri Pankov
+	  regarding Schilling's test program):
+	  + translate %02 and %03 to %2 and %3 respectively.
+	  + suppress string capabilities which use %s, not supported by tgoto
+	  + use \040 rather than \s
+	  + expand null characters as \200 rather than \0
+	+ modify configure script to support shared libraries for DragonFlyBSD.
+
+20110716
+	+ replace an assert() in _nc_Free_Argument() with a regular null
+	  pointer check (report/analysis by Franjo Ivancic).
+	+ modify configure --enable-pc-files option to take into account the
+	  PKG_CONFIG_PATH variable (report by Frederic L W Meunier).
+	+ add/use xterm+tmux chunk from xterm #271 -TD
+	+ resync xterm-new entry from xterm #271 -TD
+	+ add E3 extended capability to linux-basic (Miroslav Lichvar)
+	+ add linux2.2, linux2.6, linux3.0 entries to give context for E3 -TD
+	+ add SI/SO change to linux2.6 entry (Debian #515609) -TD
+	+ fix inconsistent tabset path in pcmw (Todd C. Miller).
+	+ remove a backslash which continued comment, obscuring altos3
+	  definition with OpenBSD toolset (Nicholas Marriott).
+
+20110702
+	+ add workaround from xterm #271 changes to ensure that compiler flags
+	  are not used in the $CC variable.
+	+ improve support for shared libraries, tested with AIX 5.3, 6.1 and
+	  7.1 with both gcc 4.2.4 and cc.
+	+ modify configure checks for AIX to include release 7.x
+	+ add loader flags/libraries to libtool options so that dynamic loading
+	  works properly, adapted from ncurses-5.7-ldflags-with-libtool.patch
+	  at gentoo prefix repository (patch by Michael Haubenwallner).
+
+20110626
+	+ move include of nc_termios.h out of term_entry.h, since the latter
+	  is installed, e.g., for tack while the former is not (report by
+	  Sven Joachim).
+
+20110625
+	+ improve cleanup() function in lib_tstp.c, using _exit() rather than
+	  exit() and checking for SIGTERM rather than SIGQUIT (prompted by
+	  comments forwarded by Nicholas Marriott).
+	+ reduce name pollution from term.h, moving fallback #define's for
+	  tcgetattr(), etc., to new private header nc_termios.h (report by
+	  Sergio NNX).
+	+ two minor fixes for tracing (patch by Vassili Courzakis).
+	+ improve trace initialization by starting it in use_env() and
+	  ripoffline().
+	+ review old email, add details for some changelog entries.
+
+20110611
+	+ update minix entry to minix 3.2 (Thomas Cort).
+	+ fix a strict compiler warning in change to wattr_get (cf: 20110528).
+
+20110604
+	+ fixes for MirBSD port:
+	  + set default prefix to /usr.
+	  + add support for shared libraries in configure script.
+	  + use S_ISREG and S_ISDIR consistently, with fallback definitions.
+	+ add a few more checks based on ncurses/link_test.
+	+ modify MKlib_gen.sh to handle sp-funcs renaming of NCURSES_OUTC type.
+
+20110528
+	+ add case to CF_SHARED_OPTS for Interix (patch by Markus Duft).
+	+ used ncurses/link_test to check for behavior when the terminal has
+	  not been initialized and when an application passes null pointers
+	  to the library.  Added checks to cover this (prompted by Redhat
+	  #707344).
+	+ modify MKlib_gen.sh to make its main() function call each function
+	  with zero parameters, to help find inconsistent checking for null
+	  pointers, etc.
+
+20110521
+	+ fix warnings from clang 2.7 "--analyze"
+
+20110514
+	+ compiler-warning fixes in panel and progs.
+	+ modify CF_PKG_CONFIG macro, from changes to tin -TD
+	+ modify CF_CURSES_FUNCS configure macro, used in test directory
+	  configure script:
+	  + work around (non-optimizer) bug in gcc 4.2.1 which caused
+	    test-expression to be omitted from executable.
+	  + force the linker to see a link-time expression of a symbol, to
+	    help work around weak-symbol issues.
+
+20110507
+	+ update discussion of MKfallback.sh script in INSTALL; normally the
+	  script is used automatically via the configured makefiles.  However
+	  there are still occasions when it might be used directly by packagers
+	  (report by Gunter Schaffler).
+	+ modify misc/ncurses-config.in to omit the "-L" option from the
+	  "--libs" output if the library directory is /usr/lib.
+	+ change order of tests for curses.h versus ncurses.h headers in the
+	  configure scripts for Ada95 and test-directories, to look for
+	  ncurses.h, from fixes to tin -TD
+	+ modify ncurses/tinfo/access.c to account for Tandem's root uid
+	  (report by Joachim Schmitz).
+
+20110430
+	+ modify rules in Ada95/src/Makefile.in to ensure that the PIC option
+	  is not used when building a static library (report by Nicolas
+	  Boulenguez):
+	+ Ada95 build-fix for big-endian architectures such as sparc.  This
+	  undoes one of the fixes from 20110319, which added an "Unused" member
+	  to representation clauses, replacing that with pragmas to suppress
+	  warnings about unused bits (patch by Nicolas Boulenguez).
+
+20110423
+	+ add check in test/configure for use_window, use_screen.
+	+ add configure-checks for getopt's variables, which may be declared
+	  as different types on some Unix systems.
+	+ add check in test/configure for some legacy curses types of the
+	  function pointer passed to tputs().
+	+ modify init_pair() to accept -1's for color value after
+	  assume_default_colors() has been called (Debian #337095).
+	+ modify test/background.c, adding commmand-line options to demonstrate
+	  assume_default_colors() and use_default_colors().
+
+20110416
+	+ modify configure script/source-code to only define _POSIX_SOURCE if
+	  the checks for sigaction and/or termios fail, and if _POSIX_C_SOURCE
+	  and _XOPEN_SOURCE are undefined (report by Valentin Ochs).
+	+ update config.guess, config.sub
+
+20110409
+	+ fixes to build c++ binding with clang 3.0 (patch by Alexander
+	  Kolesen).
+	+ add check for unctrl.h in test/configure, to work around breakage in
+	  some ncurses packages.
+	+ add "--disable-widec" option to test/configure script.
+	+ add "--with-curses-colr" and "--with-curses-5lib" options to the
+	  test/configure script to address testing with very old machines.
+
+20110404 5.9 release for upload to ftp.gnu.org
+
+20110402
+	+ various build-fixes for the rpm/dpkg scripts.
+	+ add "--enable-rpath-link" option to Ada95/configure, to allow
+	  packages to suppress the rpath feature which is normally used for
+	  the in-tree build of sample programs.
+	+ corrected definition of libdir variable in Ada95/src/Makefile.in,
+	  needed for rpm script.
+	+ add "--with-shared" option to Ada95/configure script, to allow
+	  making the C-language parts of the binding use appropriate compiler
+	  options if building a shared library with gnat.
+
+20110329
+	> portability fixes for Ada95 binding:
+	+ add configure check to ensure that SIGINT works with gnat.  This is
+	  needed for the "rain" sample program.  If SIGINT does not work, omit
+	  that sample program.
+	+ correct typo in check of $PKG_CONFIG variable in Ada95/configure
+	+ add ncurses_compat.c, to supply functions used in the Ada95 binding
+	  which were added in 5.7 and later.
+	+ modify sed expression in CF_NCURSES_ADDON to eliminate a dependency
+	  upon GNU sed.
+
+20110326
+	+ add special check in Ada95/configure script for ncurses6 reentrant
+	  code.
+	+ regen Ada html documentation.
+	+ build-fix for Ada shared libraries versus the varargs workaround.
+	+ add rpm and dpkg scripts for Ada95 and test directories, for test
+	  builds.
+	+ update test/configure macros CF_CURSES_LIBS, CF_XOPEN_SOURCE and

+	  first.  This fixes a confusion between termcap "sg" and terminfo
+	  "sgr" or "sgr0", originally from 990123 changes, but exposed by
+	  20091114 fixes for hashing.  With this change, only "dl" and "ed" are

+	+ update minix terminfo entry -TD
+	+ add bw (auto-left-margin) to nsterm* entries (Benjamin Sittler)
+
+20091212
+	+ correct transfer of multicolumn characters in multirow
+	  field_buffer(), which stopped at the end of the first row due to
+	  filling of unused entries in a cchar_t array with nulls.
+	+ updated nsterm* entries (Benjamin Sittler, Emanuele Giaquinta)

+	+ modify mk-1st.awk to allow tinfo library to be built when term-driver
+	  is enabled.
+	+ add error-check to configure script to ensure that sp-funcs is
+	  enabled if term-driver is, since some internal interfaces rely upon
+	  this.
+
+20091121
+	+ fix case where progs/tput is used while sp-funcs is configure; this
+	  requires save/restore of out-character function from _nc_prescreen
+	  rather than the SCREEN structure (report by Charles Wilson).
+	+ fix typo in man/curs_trace.3x which caused incorrect symbolic links
+	+ improved configure macros CF_GCC_ATTRIBUTES, CF_PROG_LINT.
+
+20091114

+	+ add test/xterm-256color.dat
+
+20091024
+	+ quiet some pedantic gcc warnings.
+	+ modify _nc_wgetch() to check for a -1 in the fifo, e.g., after a
+	  SIGWINCH, and discard that value, to avoid confusing application
+	  (patch by Eygene Ryabinkin, FreeBSD #136223).
+
+20091017
+	+ modify handling of $PKG_CONFIG_LIBDIR to use only the first item in

+	+ similar change for dg+ccc and dgunix+ccc
+
+20090927
+	+ move leak-checking for comp_captab.c into _nc_leaks_tinfo() since
+	  that module since 20090711 is in libtinfo.
+	+ add configure option --enable-term-driver, to allow compiling with
+	  terminal-driver.  That is used in MinGW port, and (being somewhat
+	  more complicated) is an experimental alternative to the conventional
+	  termlib internals.  Currently, it requires the sp-funcs feature to
+	  be enabled.
+	+ completed integrating "sp-funcs" by Juergen Pfeifer in ncurses
+	  library (some work remains for forms library).
+
+20090919

+	+ improve interix smso terminfo capability by using reverse rather than
+	  bold (report by Kristof Zelechovski).
+
+20090912

+	  test/test_addstr.c
+	  test/test_addwstr.c
+	  test/test_addchstr.c
+	  test/test_add_wchstr.c
+	+ correct internal _nc_insert_ch() to use _nc_insert_wch() when
+	  inserting wide characters, since the wins_wch() function that it used
+	  did not update the cursor position (report by Ciprian Craciun).
+
+20090906
+	+ fix typo s/is_timeout/is_notimeout/ which made "man is_notimeout" not
+	  work.
+	+ add null-pointer checks to other opaque-functions.

+	  in non-blocking mode (patch by Clemens Ladisch).
+	+ use PATH_SEPARATOR symbol when substituting into run_tic.sh, to
+	  help with builds on non-Unix platforms such as OS/2 EMX.
+	+ modify scripting for misc/run_tic.sh to test configure script's
+	  $cross_compiling variable directly rather than comparing host/build
+	  compiler names (prompted by comment in GenToo #249363).
+	+ fix configure script option --with-database, which was coded as an
+	  enable-type switch.
+	+ build-fixes for --srcdir (report by Frederic L W Meunier).
+
+20090808
+	+ separate _nc_find_entry() and _nc_find_type_entry() from
+	  implementation details of hash function.
+
+20090803
+	+ add tabs.1 to man/man_db.renames
+	+ modify lib_addch.c to compensate for removal of wide-character test

+
+20090718
+	+ fix a null-pointer check in _nc_format_slks() in lib_slk.c, from
+	  20090704 changes.
+	+ modify _nc_find_type_entry() to use hashing.
+	+ make CCHARW_MAX value configurable, noting that changing this would
+	  change the size of cchar_t, and would be ABI-incompatible.
+	+ modify test-programs, e.g,.  test/view.c, to address subtle
+	  differences between Tru64/Solaris and HPUX/AIX getcchar() return
+	  values.
+	+ modify length returned by getcchar() to count the trailing null
+	  which is documented in X/Open (cf: 20020427).

+
+20090404
+	+ suppress configure check for static/dynamic linker flags for gcc on
+	  Darwin (report by Nelson Beebe).

+	  with Charles Wilson).
+	+ use ncurses*-config scripts if available for test/configure.
+	+ update test/aclocal.m4 and test/configure
+	> patches by Charles Wilson:
+	+ modify CF_WITH_LIBTOOL configure check to allow unreleased libtool
+	  version numbers (e.g.  which include alphabetic chars, as well as
+	  digits, after the final '.').
+	+ improve use of -no-undefined option for libtool by setting an

+	+ fix an missing use of NCURSES_PUBLIC_VAR() in tinfo/MKcodes.awk
+	  from 20090321 changes.
+	+ improve mk-1st.awk script by writing separate cases for the
+	  LIBTOOL_LINK command, depending on which library (ncurses, ticlib,
+	  termlib) is to be linked.
+	+ modify configure.in to allow broken-linker configurations, not just
+	  enable-reentrant, to set public wrap prefix.

+
+20090314
+	+ modify scripts to generate ncurses*-config and pc-files to add

+	  Wilson, Samuel Thibault and Cedric Bretaudeau on Cygwin mailing
+	  list).
+	+ suppress configure check for static/dynamic linker flags for gcc on
+	  Solaris 10, since gcc is confused by absence of static libc, and
+	  does not switch back to dynamic mode before finishing the libraries
+	  (reports by Joel Bertrand, Alan Pae).
+	+ minor fixes to Intel compiler warning checks in configure script.
+	+ modify _nc_leaks_tinfo() so leak-checking in test/railroad.c works.

+
+20090228
+	+ continue integrating "sp-funcs" by Juergen Pfeifer (incomplete).

+
+20090214

+
+20090117
+	+ add -shared option to MK_SHARED_LIB when -Bsharable is used, for
+	  *BSD's, without which "main" might be one of the shared library's
+	  dependencies (report/analysis by Ken Dickey).
+	+ modify waddch_literal(), updating line-pointer after a multicolumn
+	  character is found to not fit on the current row, and wrapping is
+	  done.  Since the line-pointer was not updated, the wrapped
+	  multicolumn character was written to the beginning of the current row
+	  (cf: 20041023, reported by "Nick" regarding problem with ncmpc
+	  http://musicpd.org/mantis/bug_view_page.php?bug_id=1930).

+	  directory.
+	+ correct install for Ada95, which omitted libAdaCurses.a used in
+	  adacurses-config
+	+ change install for adacurses-config to provide additional flavors
+	  such as adacursesw-config, for ncursesw (GenToo #167849).
+
+20090105
+	+ remove undeveloped feature in ncurses-config.in for setting
+	  prefix variable.
+	+ recent change to ncurses-config.in did not take into account the
+	  --disable-overwrite option, which sets $includedir to the
+	  subdirectory and using just that for a -I option does not work - fix
+	  (report by Frederic L W Meunier).
+
+20090104
+	+ modify gen-pkgconfig.in to eliminate a dependency on rpath when
+	  deciding whether to add $LIBS to --libs output; that should be shown
+	  for the ncurses and tinfo libraries without taking rpath into
+	  account.
+	+ fix an overlooked change from $AR_OPTS to $ARFLAGS in mk-1st.awk,
+	  used in static libraries (report by Marty Jack).

+	  CC_SHARED_OPTS for Solaris (report by Dagobert Michelsen).
+	+ add configure --with-pkg-config and --enable-pc-files options, along
+	  with misc/gen-pkgconfig.in which can be used to generate ".pc" files

+	+ use $includedir symbol in misc/ncurses-config.in, add --includedir
+	  option.
+	+ change makefiles to use $ARFLAGS rather than $AR_OPTS, provide a

+
+20081227
+	+ modify mk-1st.awk to work with extra categories for tinfo library.
+	+ modify configure script to allow building shared libraries with gcc

+	+ modify ncurses 'F' test to demo wborder_set() with colored lines.
+	+ modify ncurses 'f' test to demo wborder() with colored lines.
+
+20081213
+	+ add check for failure to open hashed-database needed for db4.6
+	  (GenToo #245370).
+	+ corrected --without-manpages option; previous change only suppressed
+	  the auxiliary rules install.man and uninstall.man
+	+ add case for FreeMINT to configure macro CF_XOPEN_SOURCE (patch from
+	  GenToo #250454).
+	+ fixes from NetBSD port at

+	  patch-ac (build-fix for DragonFly)
+	  patch-ae (use INSTALL_SCRIPT for installing misc/ncurses*-config).
+	+ improve configure script macros CF_HEADER_PATH and CF_LIBRARY_PATH
+	  by adding CFLAGS, CPPFLAGS and LDFLAGS, LIBS values to the
+	  search-lists.

+	  work for progs/clear, progs/tabs, etc.
+	+ correct buffer-size after internal resizing of wide-character
+	  set_field_buffer(), broken in 20081018 changes (report by Mike Gran).
+	+ add "-i" option to test/filter.c to tell it to use initscr() rather
+	  than newterm(), to investigate report on comp.unix.programmer that
+	  ncurses would clear the screen in that case (it does not - the issue
+	  was xterm's alternate screen feature).
+	+ add check in mouse-driver to disable connection if GPM returns a
+	  zero, indicating that the connection is closed (Debian #506717,
+	  adapted from patch by Samuel Thibault).
+
+20081129
+	+ improve a workaround in adding wide-characters, when a control
+	  character is found.  The library (cf: 20040207) uses unctrl() to
+	  obtain a printable version of the control character, but was not
+	  passing color or video attributes.
+	+ improve test/ncurses.c 'a' test, using unctrl() more consistently to
+	  display meta-characters.
+	+ turn on _XOPEN_CURSES definition in curses.h
+	+ add eterm-color entry (report by Vincent Lefevre) -TD
+	+ correct use of key_name() in test/ncurses.c 'A' test, which only

+	+ change several terminfo entries to make consistent use of ANSI
+	  clear-all-tabs -TD
+	+ add "tabs" program (prompted by Debian #502260).
+	+ add configure --without-manpages option (request by Mike Frysinger).
+
+20081102 5.7 release for upload to ftp.gnu.org
+
+20081025
+	+ add a manpage to discuss memory leaks.
+	+ add support for shared libraries for QNX (other than libtool, which
+	  does not work well on that platform).
+	+ build-fix for QNX C++ binding.
+
+20081018
+	+ build-fixes for OS/2 EMX.
+	+ modify form library to accept control characters such as newline
+	  in set_field_buffer(), which is compatible with Solaris (report by
+	  Nit Khair).
+	+ modify configure script to assume --without-hashed-db when
+	  --disable-database is used.
+	+ add "-e" option in ncurses/Makefile.in when generating source-files
+	  to force earlier exit if the build environment fails unexpectedly
+	  (prompted by patch by Adrian Bunk).
+	+ change configure script to use CF_UTF8_LIB, improved variant of
+	  CF_LIBUTF8.

+	  20080823 (prompted by Debian #501421).
+
+20081004
+	+ some build-fixes for configure --disable-ext-funcs (incomplete, but
+	  works for C/C++ parts).
+	+ improve configure-check for awks unable to handle large strings, e.g.

+	+ add environment variable NCURSES_GPM_TERMS to allow override to use
+	  GPM on terminals other than "linux", etc.
+	+ disable GPM mouse support when $TERM does not happen to contain
+	  "linux", since Gpm_Open() no longer limits its assertion to terminals
+	  that it might handle, e.g., within "screen" in xterm.

+	  Miroslav Lichvar).
+	+ fix build for --disable-leaks --enable-widec --with-termlib

+
+20080925
+	+ fix bug in mouse code for GPM from 20080920 changes (reported in

+	+ change delimiter in MKlib_gen.sh from '%' to '@', to avoid
+	  substitution by IBM xlc to '#' as part of its extensions to digraphs.
+	+ update config.guess, config.sub from
+		http://savannah.gnu.org/projects/config
+	  (caveat - its maintainer removed support for older Linux systems).
+
+20080823
+	+ modify configure check for pthread library to work with OSF/1 5.1,
+	  which uses #define's to associate its header and library.
+	+ use pthread_mutexattr_init() for initializing pthread_mutexattr_t,
+	  makes threaded code work on HPUX 11.23
+	+ fix a bug in demo_menus in freeing menus (cf: 20080804).
+	+ modify configure script for the case where tic library is used (and
+	  possibly renamed) to remove its dependency upon ncurses/ncursew
+	  library (patch by Dr Werner Fink).
+	+ correct manpage for menu_fore() which gave wrong default for
+	  the attribute used to display a selected entry (report by Mike Gran).
+	+ add Eterm-256color, Eterm-88color and rxvt-88color (prompted by
+	  Debian #495815) -TD
+
+20080816
+	+ add configure option --enable-weak-symbols to turn on new feature.
+	+ add configure-check for availability of weak symbols.
+	+ modify linkage with pthread library to use weak symbols so that
+	  applications not linked to that library will not use the mutexes,
+	  etc.  This relies on gcc, and may be platform-specific (patch by Dr
+	  Werner Fink).
+	+ add note to INSTALL to document limitation of renaming of tic library
+	  using the --with-ticlib configure option (report by Dr Werner Fink).
+	+ document (in manpage) why tputs does not detect I/O errors (prompted
+	  by comments by Samuel Thibault).
+	+ fix remaining warnings from Klocwork report.
+
+20080804
+	+ modify _nc_panelhook() data to account for a permanent memory leak.
+	+ fix memory leaks in test/demo_menus
+	+ fix most warnings from Klocwork tool (report by Larry Zhou).
+	+ modify configure script CF_XOPEN_SOURCE macro to add case for

+	+ modify configure script --with-hashed-db to let $LIBS override the
+	  search for the db library (prompted by report by Samson Pierre).
+
+20080726
+	+ build-fixes for gcc 4.3.1 (changes to gnat "warnings", and C inlining
+	  thresholds).
+
+20080713
+	+ build-fix (reports by Christian Ebert, Funda Wang).
+
+20080712
+	+ compiler-warning fixes for Solaris.
+
+20080705
+	+ use NCURSES_MOUSE_MASK() in definition of BUTTON_RELEASE(), etc., to
+	  make those work properly with the "--enable-ext-mouse" configuration
+	  (cf: 20050205).
+	+ improve documentation of build-cc options in INSTALL.
+	+ work-around a bug in gcc 4.2.4 on AIX, which does not pass the

+
+20080628
+	+ correct some ifdef's needed for the broken-linker configuration.
+	+ make debugging library's $BAUDRATE feature work for termcap

+	+ change CC_SHARED_OPTS from -KPIC to -xcode=pic32 for Solaris.
+	+ add "-shared" option to MK_SHARED_LIB for gcc on Solaris (report
+	  by Poor Yorick).
+
+20080607
+	+ finish changes to wgetch(), making it switch as needed to the
+	  window's actual screen when calling wrefresh() and wgetnstr().  That
+	  allows wgetch() to get used concurrently in different threads with
+	  some minor restrictions, e.g., the application should not delete a
+	  window which is being used in a wgetch().
+	+ simplify mutex's, combining the window- and screen-mutex's.
+
+20080531
+	+ modify wgetch() to use the screen which corresponds to its window
+	  parameter rather than relying on SP; some dependent functions still
+	  use SP internally.
+	+ factor out most use of SP in lib_mouse.c, using parameter.
+	+ add internal _nc_keyname(), replacing keyname() to associate with a
+	  particular SCREEN rather than the global SP.
+	+ add internal _nc_unctrl(), replacing unctrl() to associate with a
+	  particular SCREEN rather than the global SP.
+	+ add internal _nc_tracemouse(), replacing _tracemouse() to eliminate
+	  its associated global buffer _nc_globals.tracemse_buf now in SCREEN.
+	+ add internal _nc_tracechar(), replacing _tracechar() to use SCREEN in
+	  preference to the global _nc_globals.tracechr_buf buffer.
+
+20080524
+	+ modify _nc_keypad() to make it switch temporarily as needed to the
+	  screen which must be updated.
+	+ wrap cur_term variable to help make _nc_keymap() thread-safe, and
+	  always set the screen's copy of this variable in set_curterm().
+	+ restore curs_set() state after endwin()/refresh() (report/patch
+	  Miroslav Lichvar)
+
+20080517
+	+ modify configure script to note that --enable-ext-colors and
+	  --enable-ext-mouse are not experimental, but extensions from
+	  the ncurses ABI 5.
+	+ corrected manpage description of setcchar() (discussion with
+	  Emanuele Giaquinta).
+	+ fix for adding a non-spacing character at the beginning of a line
+	  (report/patch by Miroslav Lichvar).
+
+20080503
+	+ modify screen.* terminfo entries using new screen+fkeys to fix
+	  overridden keys in screen.rxvt (Debian #478094) -TD
+	+ modify internal interfaces to reduce wgetch()'s dependency on the
+	  global SP.
+	+ simplify some loops with macros each_screen(), each_window() and
+	  each_ripoff().
+
+20080426
+	+ continue modifying test/ditto.c toward making it demonstrate
+	  multithreaded use_screen(), using fifos to pass data between screens.
+	+ fix typo in form.3x (report by Mike Gran).
+
+20080419
+	+ add screen.rxvt terminfo entry -TD
+	+ modify tic -f option to format spaces as \s to prevent them from
+	  being lost when that is read back in unformatted strings.
+	+ improve test/ditto.c, using a "talk"-style layout.
+
+20080412
+	+ change test/ditto.c to use openpty() and xterm.
+	+ add locks for copywin(), dupwin(), overlap(), overlay() on their
+	  window parameters.
+	+ add locks for initscr() and newterm() on updates to the SCREEN
+	  pointer.
+	+ finish table in curs_thread.3x manpage.
+
+20080405
+	+ begin table in curs_thread.3x manpage describing the scope of data
+	  used by each function (or symbol) for threading analysis.
+	+ add null-pointer checks to setsyx() and getsyx() (prompted by
+	  discussion by Martin v. Lowis and Jeroen Ruigrok van der Werven on
+	  python-dev2 mailing list).
+
+20080329
+	+ add null-pointer checks in set_term() and delscreen().
+	+ move _nc_windows into _nc_globals, since windows can be pads, which
+	  are not associated with a particular screen.
+	+ change use_screen() to pass the SCREEN* parameter rather than
+	  stdscr to the callback function.
+	+ force libtool to use tag for 'CC' in case it does not detect this,
+	  e.g., on aix when using CC=powerpc-ibm-aix5.3.0.0-gcc
+	  (report/patch by Michael Haubenwallner).
+	+ override OBJEXT to "lo" when building with libtool, to work on
+	  platforms such as AIX where libtool may use a different suffix for
+	  the object files than ".o" (report/patch by Michael Haubenwallner).
+	+ add configure --with-pthread option, for building with the POSIX
+	  thread library.
+
+20080322
+	+ fill in extended-color pair two more places in wbkgrndset() and
+	  waddch_nosync() (prompted by Sedeno's patch).
+	+ fill in extended-color pair in _nc_build_wch() to make colors work
+	  for wide-characters using extended-colors (patch by Alejandro R
+	  Sedeno).
+	+ add x/X toggles to ncurses.c C color test to test/demo
+	  wide-characters with extended-colors.
+	+ add a/A toggles to ncurses.c c/C color tests.
+	+ modify test/ditto.c to use use_screen().
+	+ finish modifying test/rain.c to demonstrate threads.
+
+20080308
+	+ start modifying test/rain.c for threading demo.
+	+ modify test/ncurses.c to make 'f' test accept the f/F/b/F/</> toggles
+	  that the 'F' accepts.
+	+ modify test/worm.c to show trail in reverse-video when other threads
+	  are working concurrently.
+	+ fix a deadlock from improper nesting of mutexes for windowlist and
+	  window.
+
+20080301
+	+ fixes from 20080223 resolved issue with mutexes; change to use
+	  recursive mutexes to fix memory leak in delwin() as called from
+	  _nc_free_and_exit().
+
+20080223
+	+ fix a size-difference in _nc_globals which caused hanging of mutex
+	  lock/unlock when termlib was built separately.
+
+20080216
+	+ avoid using nanosleep() in threaded configuration since that often
+	  is implemented to suspend the entire process.
+
+20080209
+	+ update test programs to build/work with various UNIX curses for
+	  comparisons.  This was to reinvestigate statement in X/Open Curses
+	  that insnstr and winsnstr perform wrapping.  None of the Unix-branded
+	  implementations do this, as noted in manpage (cf: 20040228).
+
+20080203
+	+ modify _nc_setupscreen() to set the legacy-coding value the same
+	  for both narrow/wide models.  It had been set only for wide model,
+	  but is needed to make unctrl() work with locale in the narrow model.
+	+ improve waddch() and winsch() handling of EILSEQ from mbrtowc() by
+	  using unctrl() to display illegal bytes rather than trying to append
+	  further bytes to make up a valid sequence (reported by Andrey A
+	  Chernov).
+	+ modify unctrl() to check codes in 128-255 range versus isprint().
+	  If they are not printable, and locale was set, use a "M-" or "~"
+	  sequence.
+
+20080126
+	+ improve threading in test/worm.c (wrap refresh calls, and KEY_RESIZE
+	  handling).  Now it hangs in napms(), no matter whether nanosleep()
+	  or poll() or select() are used on Linux.
+
+20080119
+	+ fixes to build with --disable-ext-funcs
+	+ add manpage for use_window and use_screen.
+	+ add set_tabsize() and set_escdelay() functions.
+
+20080112
+	+ remove recursive-mutex definitions, finish threading demo for worm.c
+	+ remove a redundant adjustment of lines in resizeterm.c's
+	  adjust_window() which caused occasional misadjustment of stdscr when
+	  softkeys were used.
+
+20080105
+	+ several improvements to terminfo entries based on xterm #230 -TD
+	+ modify MKlib_gen.sh to handle keyname/key_name prototypes, so the
+	  "link_test" builds properly.
+	+ fix for toe command-line options -u/-U to ensure filename is given.
+	+ fix allocation-size for command-line parsing in infocmp from 20070728
+	  (report by Miroslav Lichvar)
+	+ improve resizeterm() by moving ripped-off lines, and repainting the
+	  soft-keys (report by Katarina Machalkova)
+	+ add clarification in wclear's manpage noting that the screen will be
+	  cleared even if a subwindow is cleared (prompted by Christer Enfors
+	  question).
+	+ change test/ncurses.c soft-key tests to work with KEY_RESIZE.
+
+20071222
+	+ continue implementing support for threading demo by adding mutex
+	  for delwin().
+
+20071215
+	+ add several functions to C++ binding which wrap C functions that
+	  pass a WINDOW* parameter (request by Chris Lee).
+
+20071201
+	+ add note about configure options needed for Berkeley database to the
+	  INSTALL file.
+	+ improve checks for version of Berkeley database libraries.
+	+ amend fix for rpath to not modify LDFLAGS if the platform has no
+	  applicable transformation (report by Christian Ebert, cf: 20071124).
+
+20071124
+	+ modify configure option --with-hashed-db to accept a parameter which
+	  is the install-prefix of a given Berkeley Database (prompted by
+	  pierre4d2 comments).
+	+ rewrite wrapper for wcrtomb(), making it work on Solaris.  This is
+	  used in the form library to determine the length of the buffer needed
+	  by field_buffer (report by Alfred Fung).
+	+ remove unneeded window-parameter from C++ binding for wresize (report
+	  by Chris Lee).
+
+20071117
+	+ modify the support for filesystems which do not support mixed-case to
+	  generate 2-character (hexadecimal) codes for the lower-level of the
+	  filesystem terminfo database (request by Michail Vidiassov).
+	+ add configure option --enable-mixed-case, to allow overriding the
+	  configure script's check if the filesystem supports mixed-case
+	  filenames.
+	+ add wresize() to C++ binding (request by Chris Lee).
+	+ define NCURSES_EXT_FUNCS and NCURSES_EXT_COLORS in curses.h to make
+	  it simpler to tell if the extended functions and/or colors are
+	  declared.
+
+20071103
+	+ update memory-leak checks for changes to names.c and codes.c
+	+ correct acsc strings in h19, z100 (patch by Benjamin C W Sittler).
+
+20071020
+	+ continue implementing support for threading demo by adding mutex
+	  for use_window().
+	+ add mrxvt terminfo entry, add/fix xterm building blocks for modified
+	  cursor keys -TD
+	+ compile with FreeBSD "contemporary" TTY interface (patch by
+	  Rong-En Fan).
+
+20071013
+	+ modify makefile rules to allow clear, tput and tset to be built
+	  without libtic.  The other programs (infocmp, tic and toe) rely on
+	  that library.
+	+ add/modify null-pointer checks in several functions for SP and/or
+	  the WINDOW* parameter (report by Thorben Krueger).
+	+ fixes for field_buffer() in formw library (see Redhat #310071,
+	  patches by Miroslav Lichvar).
+	+ improve performance of NCURSES_CHAR_EQ code (patch by Miroslav
+	  Lichvar).
+	+ update/improve mlterm and rxvt terminfo entries, e.g., for
+	  the modified cursor- and keypad-keys -TD
+
+20071006
+	+ add code to curses.priv.h ifdef'd with NCURSES_CHAR_EQ, which
+	  changes the CharEq() macro to an inline function to allow comparing
+	  cchar_t struct's without comparing gaps in a possibly unpacked
+	  memory layout (report by Miroslav Lichvar).
+
+20070929
+	+ add new functions to lib_trace.c to setup mutex's for the _tracef()
+	  calls within the ncurses library.
+	+ for the reentrant model, move _nc_tputs_trace and _nc_outchars into
+	  the SCREEN.
+	+ start modifying test/worm.c to provide threading demo (incomplete).
+	+ separated ifdef's for some BSD-related symbols in tset.c, to make
+	  it compile on LynxOS (report by Greg Gemmer).
+20070915
+	+ modify Ada95/gen/Makefile to use shlib script, to simplify building
+	  shared-library configuration on platforms lacking rpath support.
+	+ build-fix for Ada95/src/Makefile to reflect changed dependency for
+	  the terminal-interface-curses-aux.adb file which is now generated.
+	+ restructuring test/worm.c, for use_window() example.
+
+20070908
+	+ add use_window() and use_screen() functions, to develop into support
+	  for threaded library (incomplete).
+	+ fix typos in man/curs_opaque.3x which kept the install script from
+	  creating symbolic links to two aliases created in 20070818 (report by
+	  Rong-En Fan).
+
+20070901
+	+ remove a spurious newline from output of html.m4, which caused links
+	  for Ada95 html to be incorrect for the files generated using m4.
+	+ start investigating mutex's for SCREEN manipulation (incomplete).
+	+ minor cleanup of codes.c/names.c for --enable-const
+	+ expand/revise "Routine and Argument Names" section of ncurses manpage
+	  to address report by David Givens in newsgroup discussion.
+	+ fix interaction between --without-progs/--with-termcap configure
+	  options (report by Michail Vidiassov).
+	+ fix typo in "--disable-relink" option (report by Michail Vidiassov).
+
+20070825
+	+ fix a sign-extension bug in infocmp's repair_acsc() function
+	  (cf: 971004).
+	+ fix old configure script bug which prevented "--disable-warnings"
+	  option from working (patch by Mike Frysinger).
+
+20070818
+	+ add 9term terminal description (request by Juhapekka Tolvanen) -TD
+	+ modify comp_hash.c's string output to avoid misinterpreting a null
+	  "\0" followed by a digit.
+	+ modify MKnames.awk and MKcodes.awk to support big-strings.
+	  This only applies to the cases (broken linker, reentrant) where
+	  the corresponding arrays are accessed via wrapper functions.
+	+ split MKnames.awk into two scripts, eliminating the shell redirection
+	  which complicated the make process and also the bogus timestamp file
+	  which was introduced to fix "make -j".
+	+ add test/test_opaque.c, test/test_arrays.c
+	+ add wgetscrreg() and wgetparent() for applications that may need it
+	  when NCURSES_OPAQUE is defined (prompted by Bryan Christ).
+
+20070812
+	+ amend treatment of infocmp "-r" option to retain the 1023-byte limit
+	  unless "-T" is given (cf: 981017).
+	+ modify comp_captab.c generation to use big-strings.
+	+ make _nc_capalias_table and _nc_infoalias_table private accessed via
+	  _nc_get_alias_table() since the tables are used only within the tic
+	  library.
+	+ modify configure script to skip Intel compiler in CF_C_INLINE.
+	+ make _nc_info_hash_table and _nc_cap_hash_table private accessed via
+	  _nc_get_hash_table() since the tables are used only within the tic
+	  library.
+
+20070728
+	+ make _nc_capalias_table and _nc_infoalias_table private, accessed via
+	  _nc_get_alias_table() since they are used only by parse_entry.c
+	+ make _nc_key_names private since it is used only by lib_keyname.c
+	+ add --disable-big-strings configure option to control whether
+	  unctrl.c is generated using the big-string optimization - which may
+	  use strings longer than supported by a given compiler.
+	+ reduce relocation tables for tic, infocmp by changing type of
+	  internal hash tables to short, and make those private symbols.
+	+ eliminate large fixed arrays from progs/infocmp.c
+
+20070721
+	+ change winnstr() to stop at the end of the line (cf: 970315).
+	+ add test/test_get_wstr.c
+	+ add test/test_getstr.c
+	+ add test/test_inwstr.c
+	+ add test/test_instr.c
+
+20070716
+	+ restore a call to obtain screen-size in _nc_setupterm(), which
+	  is used in tput and other non-screen applications via setupterm()
+	  (Debian #433357, reported by Florent Bayle, Christian Ohm,
+	  cf: 20070310).
+
+20070714
+	+ add test/savescreen.c test-program

+	+ minor fixes for ncurses/hashmap test-program.
+	+ modify configure script to quiet c++ build with libtool when the
+	  --disable-echo option is used.
+	+ modify configure script to disable ada95 if libtool is selected,
+	  writing a warning message (addresses FreeBSD #114493).
+	+ update config.guess, config.sub
+
+20070707
+	+ add continuous-move "M" to demo_panels to help test refresh changes.
+	+ improve fix for refresh of window on top of multi-column characters,
+	  taking into account some split characters on left/right window
+	  boundaries.
+
+20070630
+	+ add "widec" row to _tracedump() output to help diagnose remaining
+	  problems with multi-column characters.
+	+ partial fix for refresh of window on top of multi-column characters
+	  which are partly overwritten (report by Sadrul H Chowdhury).

+
+20070623
+	+ add test/demo_panels.c
+	+ implement opaque version of setsyx() and getsyx().
+
+20070612
+	+ corrected xterm+pcf2 terminfo modifiers for F1-F4, to match xterm
+	  #226 -TD
+	+ split-out key_name() from MKkeyname.awk since it now depends upon
+	  wunctrl() which is not in libtinfo (report by Rong-En Fan).

+20070602
+	+ adapt mouse-handling code from menu library in form-library
+	  (discussion with Clive Nicolson).
+	+ add a modification of test/dots.c, i.e., test/dots_mvcur.c to
+	  illustrate how to use mvcur().
+	+ modify wide-character flavor of SetAttr() to preserve the
+	  WidecExt() value stored in the .attr field, e.g., in case it
+	  is overwritten by chgat (report by Aleksi Torhamo).
+	+ correct buffer-size for _nc_viswbuf2n() (report by Aleksi Torhamo).
+	+ build-fixes for Solaris 2.6 and 2.7 (patch by Peter O'Gorman).
+
+20070526
+	+ modify keyname() to use "^X" form only if meta() has been called, or
+	  if keyname() is called without initializing curses, e.g., via
+	  initscr() or newterm() (prompted by LinuxBase #1604).
+	+ document some portability issues in man/curs_util.3x
+	+ add a shadow copy of TTY buffer to _nc_prescreen to fix applications
+	  broken by moving that data into SCREEN (cf: 20061230).

+	+ add 'O' (wide-character panel test) in ncurses.c to demonstrate a
+	  problem reported by Sadrul H Chowdhury with repainting parts of

+	  ripoffline(), those affect the available lines for soft-keys (adapted
+	  from patch by Clive Nicolson).
+	+ document some portability issues in man/curs_getyx.3x
+
+20070505
+	+ fix a bug in Ada95/samples/ncurses which caused a variable to

+	  memory-checking.
+	+ correct some functions in Ada95 binding which were using return value
+	  from C where none was returned:  idcok(), immedok() and wtimeout().
+	+ amend recent changes for Ada95 binding to make it build with
+	  Cygwin's linker, e.g., with configure options
+		--enable-broken-linker --with-ticlib
+
+20070428
+	+ add a configure check for gcc's options for inlining, use that to
+	  quiet a warning message where gcc's default behavior changed from
+	  3.x to 4.x.
+	+ improve warning message when checking if GPM is linked to curses
+	  library by not warning if its use of "wgetch" is via a weak symbol.
+	+ add loader options when building with static libraries to ensure that
+	  an installed shared library for ncurses does not conflict.  This is
+	  reported as problem with Tru64, but could affect other platforms
+	  (report Martin Mokrejs, analysis by Tim Mooney).
+	+ fix build on cygwin after recent ticlib/termlib changes, i.e.,
+	  + adjust TINFO_SUFFIX value to work with cygwin's dll naming
+	  + revert a change from 20070303 which commented out dependency of
+	    SHLIB_LIST in form/menu/panel/c++ libraries.

+
+20070421
+	+ move most static variables into structures _nc_globals and

+	  comment on comp.lang.ada newsgroup).
+	+ fix includes in c++ binding to build with Intel compiler
+	  (cf: 20061209).
+	+ update install rule in Ada95 to use mkdirs.sh

+	+ remove an unused assignment in progs/infocmp.c
+	+ fix a limit check in tack/ansi.c tools_charset()
+	+ fix tack/ansi.c tools_status() to perform the VT320/VT420

+	+ fix a couple of places in tack/output.c which did not check for EOF.
+	+ fix a loop-condition in test/bs.c

+	+ add try/catch block to c++/cursesmain.cc
+
+20070331
+	+ modify Ada95 binding to build with --enable-reentrant by wrapping
+	  global variables (bug: acs_map does not yet work).
+	+ modify Ada95 binding to use the new access-functions, allowing it
+	  to build/run when NCURSES_OPAQUE is set.
+	+ add access-functions and macros to return properties of the WINDOW
+	  structure, e.g., when NCURSES_OPAQUE is set.
+	+ improved install-sh's quoting.
+	+ use mkdirs.sh rather than mkinstalldirs, e.g., to use fixes from
+	  other programs.
+
+20070324
+	+ eliminate part of the direct use of WINDOW data from Ada95 interface.
+	+ fix substitutions for termlib filename to make configure option
+	  --enable-reentrant work with --with-termlib.
+	+ change a constructor for NCursesWindow to allow compiling with
+	  NCURSES_OPAQUE set, since we cannot pass a reference to
+	  an opaque pointer.
+
+20070317
+	+ ignore --with-chtype=unsigned since unsigned is always added to
+	  the type in curses.h; do the same for --with-mmask-t.
+	+ change warning regarding --enable-ext-colors and wide-character
+	  in the configure script to an error.
+	+ tweak error message in CF_WITH_LIBTOOL to distinguish other programs
+	  such as Darwin's libtool program (report by Michail Vidiassov)
+	+ modify edit_man.sh to allow for multiple substitutions per line.
+	+ set locale in misc/ncurses-config.in since it uses a range
+	+ change permissions libncurses++.a install (report by Michail
+	  Vidiassov).
+	+ corrected length of temporary buffer in wide-character version
+	  of set_field_buffer() (related to report by Bryan Christ).
+
+20070311
+	+ fix mk-1st.awk script install_shlib() function, broken in 20070224
+	  changes for cygwin (report by  Michail Vidiassov).
+
+20070310
+	+ increase size of array in _nc_visbuf2n() to make "tic -v" work
+	  properly in its similar_sgr() function (report/analysis by Peter
+	  Santoro).
+	+ add --enable-reentrant configure option for ongoing changes to
+	  implement a reentrant version of ncurses:
+	  + libraries are suffixed with "t"
+	  + wrap several global variables (curscr, newscr, stdscr, ttytype,
+	    COLORS, COLOR_PAIRS, COLS, ESCDELAY, LINES and TABSIZE) as
+	    functions returning values stored in SCREEN or cur_term.
+	  + move some initialization (LINES, COLS) from lib_setup.c,
+	    i.e., setupterm() to _nc_setupscreen(), i.e., newterm().
+
+20070303
+	+ regenerated html documentation.
+	+ add NCURSES_OPAQUE symbol to curses.h, will use to make structs
+	  opaque in selected configurations.
+	+ move the chunk in lib_acs.c which resets acs capabilities when
+	  running on a terminal whose locale interferes with those into
+	  _nc_setupscreen(), so the libtinfo/libtinfow files can be made
+	  identical (requested by Miroslav Lichvar).
+	+ do not use configure variable SHLIB_LIBS for building libraries
+	  outside the ncurses directory, since that symbol is customized
+	  only for that directory, and using it introduces an unneeded
+	  dependency on libdl (requested by Miroslav Lichvar).
+	+ modify mk-1st.awk so the generated makefile rules for linking or
+	  installing shared libraries do not first remove the library, in
+	  case it is in use, e.g., libncurses.so by /bin/sh (report by Jeff
+	  Chua).
+	+ revised section "Using NCURSES under XTERM" in ncurses-intro.html
+	  (prompted by newsgroup comment by Nick Guenther).
+
+20070224
+	+ change internal return codes of _nc_wgetch() to check for cases
+	  where KEY_CODE_YES should be returned, e.g., if a KEY_RESIZE was
+	  ungetch'd, and read by wget_wch().
+	+ fix static-library build broken in 20070217 changes to remove "-ldl"
+	  (report by Miroslav Lichvar).
+	+ change makefile/scripts for cygwin to allow building termlib.
+	+ use Form_Hook in manpages to match form.h
+	+ use Menu_Hook in manpages, as well as a few places in menu.h
+	+ correct form- and menu-manpages to use specific Field_Options,
+	  Menu_Options and Item_Options types.
+	+ correct prototype for _tracechar() in manpage (cf: 20011229).
+	+ correct prototype for wunctrl() in manpage.
+
+20070217
+	+ fixes for $(TICS_LIST) in ncurses/Makefile (report by Miroslav
+	  Lichvar).
+	+ modify relinking of shared libraries to apply only when rpath is
+	  enabled, and add --disable-relink option which can be used to
+	  disable the feature altogether (reports by Michail Vidiassov,
+	  Adam J Richter).
+	+ fix --with-termlib option for wide-character configuration, stripping
+	  the "w" suffix in one place (report by Miroslav Lichvar).
+	+ remove "-ldl" from some library lists to reduce dependencies in
+	  programs (report by Miroslav Lichvar).
+	+ correct description of --enable-signed-char in configure --help
+	  (report by Michail Vidiassov).
+	+ add pattern for GNU/kFreeBSD configuration to CF_XOPEN_SOURCE,
+	  which matches an earlier change to CF_SHARED_OPTS, from xterm #224
+	  fixes.
+	+ remove "${DESTDIR}" from -install_name option used for linking
+	  shared libraries on Darwin (report by Michail Vidiassov).
+
+20070210
+	+ add test/inchs.c, test/inch_wide.c, to test win_wchnstr().
+	+ remove libdl from library list for termlib (report by Miroslav
+	  Lichvar).
+	+ fix configure.in to allow --without-progs --with-termlib (patch by
+	  Miroslav Lichvar).
+	+ modify win_wchnstr() to ensure that only a base cell is returned
+	  for each multi-column character (prompted by report by Wei Kong
+	  regarding change in mvwin_wch() cf: 20041023).
+
+20070203
+	+ modify fix_wchnstr() in form library to strip attributes (and color)
+	  from the cchar_t array (field cells) read from a field's window.
+	  Otherwise, when copying the field cells back to the window, the
+	  associated color overrides the field's background color (report by
+	  Ricardo Cantu).
+	+ improve tracing for form library, showing created forms, fields, etc.
+	+ ignore --enable-rpath configure option if --with-shared was omitted.
+	+ add _nc_leaks_tinfo(), _nc_free_tic(), _nc_free_tinfo() entrypoints
+	  to allow leak-checking when both tic- and tinfo-libraries are built.
+	+ drop CF_CPP_VSCAN_FUNC macro from configure script, since C++ binding
+	  no longer relies on it.
+	+ disallow combining configure script options --with-ticlib and
+	  --enable-termcap (report by Rong-En Fan).
+	+ remove tack from ncurses tree.
+
+20070128
+	+ fix typo in configure script that broke --with-termlib option
+	  (report by Rong-En Fan).
+
+20070127
+	+ improve fix for FreeBSD gnu/98975, to allow for null pointer passed
+	  to tgetent() (report by Rong-en Fan).
+	+ update tack/HISTORY and tack/README to tell how to build it after
+	  it is removed from the ncurses tree.
+	+ fix configure check for libtool's version to trim blank lines
+	  (report by sci-fi@hush.ai).
+	+ review/eliminate other original-file artifacts in cursesw.cc, making
+	  its license consistent with ncurses.
+	+ use ncurses vw_scanw() rather than reading into a fixed buffer in
+	  the c++ binding for scanw() methods (prompted by report by Nuno Dias).
+	+ eliminate fixed-buffer vsprintf() calls in c++ binding.
+
+20070120
+	+ add _nc_leaks_tic() to separate leak-checking of tic library from
+	  term/ncurses libraries, and thereby eliminate a library dependency.
+	+ fix test/mk-test.awk to ignore blank lines.
+	+ correct paths in include/headers, for --srcdir (patch by Miroslav
+	  Lichvar).
+
+20070113
+	+ add a break-statement in misc/shlib to ensure that it exits on the
+	  _first_ matched directory (report by Paul Novak).
+	+ add tack/configure, which can be used to build tack outside the
+	  ncurses build-tree.
+	+ add --with-ticlib option, to build/install the tic-support functions
+	  in a separate library (suggested by Miroslav Lichvar).
+
+20070106
+	+ change MKunctrl.awk to reduce relocation table for unctrl.o
+	+ change MKkeyname.awk to reduce relocation table for keyname.o
+	  (patch by Miroslav Lichvar).
+
+20061230
+	+ modify configure check for libtool's version to trim blank lines
+	  (report by sci-fi@hush.ai).
+	+ modify some modules to allow them to be reentrant if _REENTRANT is
+	  defined: lib_baudrate.c, resizeterm.c (local data only)
+	+ eliminate static data from some modules: add_tries.c, hardscroll.c,
+	  lib_ttyflags.c, lib_twait.c
+	+ improve manpage install to add aliases for the transformed program
+	  names, e.g., from --program-prefix.
+	+ used linklint to verify links in the HTML documentation, made fixes
+	  to manpages as needed.
+	+ fix a typo in curs_mouse.3x (report by William McBrine).
+	+ fix install-rule for ncurses5-config to make the bin-directory.
+
+20061223
+	+ modify configure script to omit the tic (terminfo compiler) support
+	  from ncurses library if --without-progs option is given.
+	+ modify install rule for ncurses5-config to do this via "install.libs"
+	+ modify shared-library rules to allow FreeBSD 3.x to use rpath.
+	+ update config.guess, config.sub
+
+20061217 5.6 release for upload to ftp.gnu.org
+
+20061217
+	+ add ifdef's for <wctype.h> for HPUX, which has the corresponding
+	  definitions in <wchar.h>.
+	+ revert the va_copy() change from 20061202, since it was neither
+	  correct nor portable.
+	+ add $(LOCAL_LIBS) definition to progs/Makefile.in, needed for
+	  rpath on Solaris.
+	+ ignore wide-acs line-drawing characters that wcwidth() claims are
+	  not one-column.  This is a workaround for Solaris' broken locale
+	  support.
+
+20061216
+	+ modify configure --with-gpm option to allow it to accept a parameter,
+	  i.e., the name of the dynamic GPM library to load via dlopen()
+	  (requested by Bryan Henderson).
+	+ add configure option --with-valgrind, changes from vile.
+	+ modify configure script AC_TRY_RUN and AC_TRY_LINK checks to use
+	  'return' in preference to 'exit()'.
+
+20061209
+	+ change default for --with-develop back to "no".
+	+ add XTABS to tracing of TTY bits.
+	+ updated autoconf patch to ifdef-out the misfeature which declares
+	  exit() for configure tests.  This fixes a redefinition warning on
+	  Solaris.
+	+ use ${CC} rather than ${LD} in shared library rules for IRIX64,
+	  Solaris to help ensure that initialization sections are provided for
+	  extra linkage requirements, e.g., of C++ applications (prompted by
+	  comment by Casper Dik in newsgroup).
+	+ rename "$target" in CF_MAN_PAGES to make it easier to distinguish
+	  from the autoconf predefined symbol.  There was no conflict,
+	  since "$target" was used only in the generated edit_man.sh file,
+	  but SuSE's rpm package contains a patch.
+
+20061202
+	+ update man/term.5 to reflect extended terminfo support and hashed
+	  database configuration.
+	+ updates for test/configure script.
+	+ adapted from SuSE rpm package:
+	  + remove long-obsolete workaround for broken-linker which declared
+	    cur_term in tic.c
+	  + improve error recovery in PUTC() macro when wcrtomb() does not
+	    return usable results for an 8-bit character.
+	+ patches from rpm package (SuSE):
+	  + use va_copy() in extra varargs manipulation for tracing version
+	    of printw, etc.
+	  + use a va_list rather than a null in _nc_freeall()'s call to
+	    _nc_printf_string().
+	+ add some see-also references in manpages to show related
+	  wide-character functions (suggested by Claus Fischer).
+
+20061125
+	+ add a check in lib_color.c to ensure caller does not increase COLORS
+	  above max_colors, which is used as an array index (discussion with
+	  Simon Sasburg).
+	+ add ifdef's allowing ncurses to be built with tparm() using either
+	  varargs (the existing status), or using a fixed-parameter list (to
+	  match X/Open).
+
+20061104
+	+ fix redrawing of windows other than stdscr using wredrawln() by
+	  touching the corresponding rows in curscr (discussion with Dan
+	  Gookin).
+	+ add test/redraw.c
+	+ add test/echochar.c
+	+ review/cleanup manpage descriptions of error-returns for form- and
+	  menu-libraries (prompted by FreeBSD docs/46196).
+
+20061028
+	+ add AUTHORS file -TD
+	+ omit the -D options from output of the new config script --cflags
+	  option (suggested by Ralf S Engelschall).
+	+ make NCURSES_INLINE unconditionally defined in curses.h
+
+20061021
+	+ revert change to accommodate bash 3.2, since that breaks other
+	  platforms, e.g., Solaris.

+	  contributors.
+	+ improve some shared-library configure scripting for Linux, FreeBSD
+	  and NetBSD to make "--with-shlib-version" work.

+	  for rpath support in versions past 3.
+	+ use $(DESTDIR) in makefile rules for installing/uninstalling the
+	  package config script (reports/patches by Christian Wiese,
+	  Ralf S Engelschall).
+	+ fix a warning in the configure script for NetBSD 2.0, working around
+	  spurious blanks embedded in its ${MAKEFLAGS} symbol.
+	+ change test/Makefile to simplify installing test programs in a
+	  different directory when --enable-rpath is used.
+
+20061014
+	+ work around bug in bash 3.2 by adding extra quotes (Jim Gifford).
+	+ add/install a package config script, e.g., "ncurses5-config" or
+	  "ncursesw5-config", according to configuration options.
+
+20061007
+	+ add several GNU Screen terminfo variations with 16- and 256-colors,
+	  and status line (Alain Bench).
+	+ change the way shared libraries (other than libtool) are installed.
+	  Rather than copying the build-tree's libraries, link the shared
+	  objects into the install directory.  This makes the --with-rpath
+	  option work except with $(DESTDIR) (cf: 20000930).
+
+20060930
+	+ fix ifdef in c++/internal.h for QNX 6.1
+	+ test-compiled with (old) egcs-1.1.2, modified configure script to
+	  not unset the $CXX and related variables which would prevent this.

+	  (report by Michail Vidiassov).
+	+ modify CF_PATH_SYNTAX to ensure it uses the result from --prefix
+	  option (from lynx changes) -TD
+	+ adapt AC_PROG_EGREP check, noting that this is likely to be another
+	  place aggravated by POSIXLY_CORRECT.
+	+ modify configure check for awk to ensure that it is found (prompted
+	  by report by Christopher Parker).
+	+ update config.sub
+
+20060909
+	+ add kon, kon2 and jfbterm terminfo entry (request by Till Maas) -TD
+	+ remove invis capability from klone+sgr, mainly used by linux entry,
+	  since it does not really do this -TD
+
+20060903
+	+ correct logic in wadd_wch() and wecho_wch(), which did not guard
+	  against passing the multi-column attribute into a call on waddch(),
+	  e.g., using data returned by win_wch() (cf: 20041023)
+	  (report by Sadrul H Chowdhury).
+
+20060902
+	+ fix kterm's acsc string -TD
+	+ fix for change to tic/infocmp in 20060819 to ensure no blank is
+	  embedded into a termcap description.

+	  when using --with-termlib --with-trace options.
+	+ improve tgetstr() by making the return value point into the user's
+	  buffer, if provided (patch by Miroslav Lichvar (see Redhat #202480)).
+	+ correct libraries needed for foldkeys (report by Stanislav Ievlev)
+
+20060826
+	+ add terminfo entries for xfce terminal (xfce) and multi gnome
+	  terminal (mgt) -TD
+	+ add test/foldkeys.c
+
+20060819
+	+ modify tic and infocmp to avoid writing trailing blanks on terminfo
+	  source output (Debian #378783).
+	+ modify configure script to ensure that if the C compiler is used
+	  rather than the loader in making shared libraries, the $(CFLAGS)
+	  variable is also used (Redhat #199369).
+	+ port hashed-db code to db2 and db3.
+	+ fix a bug in tgetent() from 20060625 and 20060715 changes
+	  (patch/analysis by Miroslav Lichvar (see Redhat #202480)).
+
+20060805
+	+ updated xterm function-keys terminfo to match xterm #216 -TD
+	+ add configure --with-hashed-db option (tested only with FreeBSD 6.0,
+	  e.g., the db 1.8.5 interface).
+
+20060729
+	+ modify toe to access termcap data, e.g., via cgetent() functions,
+	  or as a text file if those are not available.
+	+ use _nc_basename() in tset to improve $SHELL check for csh/sh.
+	+ modify _nc_read_entry() and _nc_read_termcap_entry() so infocmp,
+	  can access termcap data when the terminfo database is disabled.
+
+20060722
+	+ widen the test for xterm kmous a little to allow for other strings
+	  than \E[M, e.g., for xterm-sco functionality in xterm.
+	+ update xterm-related terminfo entries to match xterm patch #216 -TD
+	+ update config.guess, config.sub
+
+20060715
+	+ fix for install-rule in Ada95 to add terminal_interface.ads
+	  and terminal_interface.ali (anonymous posting in comp.lang.ada).
+	+ correction to manpage for getcchar() (report by William McBrine).
+	+ add test/chgat.c
+	+ modify wchgat() to mark updated cells as changed so a refresh will
+	  repaint those cells (comments by Sadrul H Chowdhury and William
+	  McBrine).
+	+ split up dependency of names.c and codes.c in ncurses/Makefile to
+	  work with parallel make (report/analysis by Joseph S Myers).
+	+ suppress a warning message (which is ignored) for systems without
+	  an ldconfig program (patch by Justin Hibbits).
+	+ modify configure script --disable-symlinks option to allow one to
+	  disable symlink() in tic even when link() does not work (report by
+	  Nigel Horne).
+	+ modify MKfallback.sh to use tic -x when constructing fallback tables
+	  to allow extended capabilities to be retrieved from a fallback entry.
+	+ improve leak-checking logic in tgetent() from 20060625 to ensure that
+	  it does not free the current screen (report by Miroslav Lichvar).
+
+20060708
+	+ add a check for _POSIX_VDISABLE in tset (NetBSD #33916).
+	+ correct _nc_free_entries() and related functions used for memory leak
+	  checking of tic.
+
+20060701
+	+ revert a minor change for magic-cookie support from 20060513, which
+	  caused unexpected reset of attributes, e.g., when resizing test/view
+	  in color mode.
+	+ note in clear manpage that the program ignores command-line
+	  parameters (prompted by Debian #371855).
+	+ fixes to make lib_gen.c build properly with changes to the configure
+	  --disable-macros option and NCURSES_NOMACROS (cf:  20060527)
+	+ update/correct several terminfo entries -TD
+	+ add some notes regarding copyright to terminfo.src -TD
+
+20060625
+	+ fixes to build Ada95 binding with gnat-4.1.0
+	+ modify read_termtype() so the term_names data is always allocated as
+	  part of the str_table, a better fix for a memory leak (cf: 20030809).
+	+ reduce memory leaks in repeated calls to tgetent() by remembering the
+	  last TERMINAL* value allocated to hold the corresponding data and
+	  freeing that if the tgetent() result buffer is the same as the
+	  previous call (report by "Matt" for FreeBSD gnu/98975).
+	+ modify tack to test extended capability function-key strings.
+	+ improved gnome terminfo entry (GenToo #122566).
+	+ improved xterm-256color terminfo entry (patch by Alain Bench).
+
+20060617
+	+ fix two small memory leaks related to repeated tgetent() calls
+	  with TERM=screen (report by "Matt" for FreeBSD gnu/98975).
+	+ add --enable-signed-char to simplify Debian package.
+	+ reduce name-pollution in term.h by removing #define's for HAVE_xxx
+	  symbols.
+	+ correct typo in curs_terminfo.3x (Debian #369168).
+
+20060603
+	+ enable the mouse in test/movewindow.c
+	+ improve a limit-check in frm_def.c (John Heasley).
+	+ minor copyright fixes.
+	+ change configure script to produce test/Makefile from data file.
+
+20060527
+	+ add a configure option --enable-wgetch-events to enable
+	  NCURSES_WGETCH_EVENTS, and correct the associated loop-logic in
+	  lib_twait.c (report by Bernd Jendrissek).
+	+ remove include/nomacros.h from build, since the ifdef for
+	  NCURSES_NOMACROS makes that obsolete.
+	+ add entrypoints for some functions which were only provided as macros
+	  to make NCURSES_NOMACROS ifdef work properly:  getcurx(), getcury(),
+	  getbegx(), getbegy(), getmaxx(), getmaxy(), getparx() and getpary(),
+	  wgetbkgrnd().
+	+ provide ifdef for NCURSES_NOMACROS which suppresses most macro
+	  definitions from curses.h, i.e., where a macro is defined to override
+	  a function to improve performance.  Allowing a developer to suppress
+	  these definitions can simplify some application (discussion with
+	  Stanislav Ievlev).
+	+ improve description of memu/meml in terminfo manpage.
+
+20060520
+	+ if msgr is false, reset video attributes when doing an automargin
+	  wrap to the next line.  This makes the ncurses 'k' test work properly
+	  for hpterm.
+	+ correct caching of keyname(), which was using only half of its table.
+	+ minor fixes to memory-leak checking.
+	+ make SCREEN._acs_map and SCREEN._screen_acs_map pointers rather than
+	  arrays, making ACS_LEN less visible to applications (suggested by
+	  Stanislav Ievlev).
+	+ move chunk in SCREEN ifdef'd for USE_WIDEC_SUPPORT to the end, so
+	  _screen_acs_map will have the same offset in both ncurses/ncursesw,
+	  making the corresponding tinfo/tinfow libraries binary-compatible
+	  (cf: 20041016, report by Stanislav Ievlev).
+
+20060513
+	+ improve debug-tracing for EmitRange().
+	+ change default for --with-develop to "yes".  Add NCURSES_NO_HARD_TABS
+	  and NCURSES_NO_MAGIC_COOKIE environment variables to allow runtime
+	  suppression of the related hard-tabs and xmc-glitch features.
+	+ add ncurses version number to top-level manpages, e.g., ncurses, tic,
+	  infocmp, terminfo as well as form, menu, panel.
+	+ update config.guess, config.sub
+	+ modify ncurses.c to work around a bug in NetBSD 3.0 curses
+	  (field_buffer returning null for a valid field).  The 'r' test
+	  appears to not work with that configuration since the new_fieldtype()
+	  function is broken in that implementation.
+
+20060506
+	+ add hpterm-color terminfo entry -TD
+	+ fixes to compile test-programs with HPUX 11.23
+
+20060422
+	+ add copyright notices to files other than those that are generated,
+	  data or adapted from pdcurses (reports by William McBrine, David
+	  Taylor).
+	+ improve rendering on hpterm by not resetting attributes at the end
+	  of doupdate() if the terminal has the magic-cookie feature (report
+	  by Bernd Rieke).
+	+ add 256color variants of terminfo entries for programs which are
+	  reported to implement this feature -TD
+
+20060416
+	+ fix typo in change to NewChar() macro from 20060311 changes, which
+	  broke tab-expansion (report by Frederic L W Meunier).
+
+20060415
+	+ document -U option of tic and infocmp.
+	+ modify tic/infocmp to suppress smacs/rmacs when acsc is suppressed
+	  due to size limit, e.g., converting to termcap format.  Also
+	  suppress them if the output format does not contain acsc and it
+	  was not VT100-like, i.e., a one-one mapping (Novell #163715).
+	+ add configure check to ensure that SIGWINCH is defined on platforms
+	  such as OS X which exclude that when _XOPEN_SOURCE, etc., are
+	  defined (report by Nicholas Cole)
+
+20060408
+	+ modify write_object() to not write coincidental extensions of an
+	  entry made due to it being referenced in a use= clause (report by
+	  Alain Bench).
+	+ another fix for infocmp -i option, which did not ensure that some
+	  escape sequences had comparable prefixes (report by Alain Bench).
+
+20060401
+	+ improve discussion of init/reset in terminfo and tput manpages
+	  (report by Alain Bench).
+	+ use is3 string for a fallback of rs3 in the reset program; it was
+	  using is2 (report by Alain Bench).
+	+ correct logic for infocmp -i option, which did not account for
+	  multiple digits in a parameter (cf: 20040828) (report by Alain
+	  Bench).
+	+ move _nc_handle_sigwinch() to lib_setup.c to make --with-termlib
+	  option work after 20060114 changes (report by Arkadiusz Miskiewicz).
+	+ add copyright notices to test-programs as needed (report by William
+	  McBrine).
+
+20060318
+	+ modify ncurses.c 'F' test to combine the wide-characters with color
+	  and/or video attributes.
+	+ modify test/ncurses to use CTL/Q or ESC consistently for exiting
+	  a test-screen (some commands used 'x' or 'q').
+
+20060312
+	+ fix an off-by-one in the scrolling-region change (cf_ 20060311).
+
+20060311
+	+ add checks in waddchnstr() and wadd_wchnstr() to stop copying when
+	  a null character is found (report by Igor Bogomazov).
+	+ modify progs/Makefile.in to make "tput init" work properly with
+	  cygwin, i.e., do not pass a ".exe" in the reference string used
+	  in check_aliases (report by Samuel Thibault).
+	+ add some checks to ensure current position is within scrolling
+	  region before scrolling on a new line (report by Dan Gookin).
+	+ change some NewChar() usage to static variables to work around
+	  stack garbage introduced when cchar_t is not packed (Redhat #182024).
+
+20060225
+	+ workarounds to build test/movewindow with PDcurses 2.7.
+	+ fix for nsterm-16color entry (patch by Alain Bench).
+	+ correct a typo in infocmp manpage (Debian #354281).
+
+20060218
+	+ add nsterm-16color entry -TD
+	+ updated mlterm terminfo entry -TD
+	+ remove 970913 feature for copying subwindows as they are moved in
+	  mvwin() (discussion with Bryan Christ).
+	+ modify test/demo_menus.c to demonstrate moving a menu (both the
+	  window and subwindow) using shifted cursor-keys.
+	+ start implementing recursive mvwin() in movewindow.c (incomplete).
+	+ add a fallback definition for GCC_PRINTFLIKE() in test.priv.h,
+	  for movewindow.c (report by William McBrine).
+	+ add help-message to test/movewindow.c
+
+20060211
+	+ add test/movewindow.c, to test mvderwin().
+	+ fix ncurses soft-key test so color changes are shown immediately
+	  rather than delayed.
+	+ modify ncurses soft-key test to hide the keys when exiting the test
+	  screen.
+	+ fixes to build test programs with PDCurses 2.7, e.g., its headers
+	  rely on autoconf symbols, and it declares stubs for nonfunctional
+	  terminfo and termcap entrypoints.
+
+20060204
+	+ improved test/configure to build test/ncurses on HPUX 11 using the
+	  vendor curses.
+	+ documented ALTERNATE CONFIGURATIONS in the ncurses manpage, for the
+	  benefit of developers who do not read INSTALL.
+
+20060128
+	+ correct form library Window_To_Buffer() change (cf:  20040516), which
+	  should ignore the video attributes (report by Ricardo Cantu).
+
+20060121
+	+ minor fixes to xmc-glitch experimental code:
+	  + suppress line-drawing
+	  + implement max_attributes
+	  tested with xterm.
+	+ minor fixes for the database iterator.
+	+ fix some buffer limits in c++ demo (comment by Falk Hueffner in
+	  Debian #348117).
+
+20060114
+	+ add toe -a option, to show all databases.  This uses new private
+	  interfaces in the ncurses library for iterating through the list of
+	  databases.
+	+ fix toe from 20000909 changes which made it not look at
+	  $HOME/.terminfo
+	+ make toe's -v option parameter optional as per manpage.
+	+ improve SIGWINCH handling by postponing its effect during newterm(),
+	  etc., when allocating screens.
+
+20060111
+	+ modify wgetnstr() to return KEY_RESIZE if a sigwinch occurs.  Use
+	  this in test/filter.c
+	+ fix an error in filter() modification which caused some applications
+	  to fail.
+
+20060107
+	+ check if filter() was called when getting the screensize.  Keep it
+	  at 1 if so (based on Redhat #174498).
+	+ add extension nofilter().
+	+ refined the workaround for ACS mapping.
+	+ make ifdef's consistent in curses.h for the extended colors so the
+	  header file can be used for the normal curses library.  The header
+	  file installed for extended colors is a variation of the
+	  wide-character configuration (report by Frederic L W Meunier).
+
+20051231
+	+ add a workaround to ACS mapping to allow applications such as
+	  test/blue.c to use the "PC ROM" characters by masking them with
+	  A_ALTCHARSET.  This worked up til 5.5, but was lost in the revision
+	  of legacy coding (report by Michael Deutschmann).
+	+ add a null-pointer check in the wide-character version of
+	  calculate_actual_width() (report by Victor Julien).
+	+ improve test/ncurses 'd' (color-edit) test by allowing the RGB
+	  values to be set independently (patch by William McBrine).
+	+ modify test/configure script to allow building test programs with
+	  PDCurses/X11.
+	+ modified test programs to allow some to work with NetBSD curses.
+	  Several do not because NetBSD curses implements a subset of X/Open
+	  curses, and also lacks much of SVr4 additions.  But it's enough for
+	  comparison.
+	+ update config.guess and config.sub
+
+20051224
+	+ use BSD-specific fix for return-value from cgetent() from CVS where
+	  an unknown terminal type would be reportd as "database not found".
+	+ make tgetent() return code more readable using new symbols
+	  TGETENT_YES, etc.
+	+ remove references to non-existent "tctest" program.
+	+ remove TESTPROGS from progs/Makefile.in (it was referring to code
+	  that was never built in that directory).
+	+ typos in curs_addchstr.3x, some doc files (noticed in OpenBSD CVS).
+
+20051217
+	+ add use_legacy_coding() function to support lynx's font-switching
+	  feature.
+	+ fix formatting in curs_termcap.3x (report by Mike Frysinger).
+	+ modify MKlib_gen.sh to change preprocessor-expanded _Bool back to
+	  bool.
+
+20051210
+	+ extend test/ncurses.c 's' (overlay window) test to exercise overlay(),
+	  overwrite() and copywin() with different combinations of colors and
+	  attributes (including background color) to make it easy to see the
+	  effect of the different functions.
+	+ corrections to menu/m_global.c for wide-characters (report by
+	  Victor Julien).
+
+20051203
+	+ add configure option --without-dlsym, allowing developers to
+	  configure GPM support without using dlsym() (discussion with Michael
+	  Setzer).
+	+ fix wins_nwstr(), which did not handle single-column non-8bit codes
+	  (Debian #341661).
+
+20051126
+	+ move prototypes for wide-character trace functions from curses.tail
+	  to curses.wide to avoid accidental reference to those if
+	  _XOPEN_SOURCE_EXTENDED is defined without ensuring that <wchar.h> is
+	  included.
+	+ add/use NCURSES_INLINE definition.
+	+ change some internal functions to use int/unsigned rather than the
+	  short equivalents.
+
+20051119
+	+ remove a redundant check in lib_color.c (Debian #335655).
+	+ use ld's -search_paths_first option on Darwin to work around odd
+	  search rules on that platform (report by Christian Gennerat, analysis
+	  by Andrea Govoni).
+	+ remove special case for Darwin in CF_XOPEN_SOURCE configure macro.
+	+ ignore EINTR in tcgetattr/tcsetattr calls (Debian #339518).
+	+ fix several bugs in test/bs.c (patch by Stephen Lindholm).
+
+20051112
+	+ other minor fixes to cygwin based on tack -TD
+	+ correct smacs in cygwin (Debian #338234, report by Baurzhan
+	  Ismagulov, who noted that it was fixed in Cygwin).
+
+20051029
+	+ add shifted up/down arrow codes to xterm-new as kind/kri strings -TD
+	+ modify wbkgrnd() to avoid clearing the A_CHARTEXT attribute bits
+	  since those record the state of multicolumn characters (Debian
+	  #316663).
+	+ modify werase to clear multicolumn characters that extend into
+	  a derived window (Debian #316663).
+
+20051022
+	+ move assignment from environment variable ESCDELAY from initscr()
+	  down to newterm() so the environment variable affects timeouts for
+	  terminals opened with newterm() as well.
+	+ fix a memory leak in keyname().
+	+ add test/demo_altkeys.c
+	+ modify test/demo_defkey.c to exit from loop via 'q' to allow
+	  leak-checking, as well as fix a buffer size in winnstr() call.
+
+20051015
+	+ correct order of use-clauses in rxvt-basic entry which made codes for
+	  f1-f4 vt100-style rather than vt220-style (report by Gabor Z Papp).
+	+ suppress configure check for gnatmake if Ada95/Makefile.in is not
+	  found.
+	+ correct a typo in configure --with-bool option for the case where
+	  --without-cxx is used (report by Daniel Jacobowitz).
+	+ add a note to INSTALL's discussion of --with-normal, pointing out
+	  that one may wish to use --without-gpm to ensure a completely
+	  static link (prompted by report by Felix von Leitner).
+
+20051010 5.5 release for upload to ftp.gnu.org
+
+20051008
+	+ document in demo_forms.c some portability issues.
+
+20051001
+	+ document side-effect of werase() which sets the cursor position.
+	+ save/restore the current position in form field editing to make
+	  overlay mode work.
+
+20050924
+	+ correct header dependencies in progs, allowing parallel make (report
+	  by Daniel Jacobowitz).
+	+ modify CF_BUILD_CC to ensure that pre-setting $BUILD_CC overrides
+	  the configure check for --with-build-cc (report by Daniel Jacobowitz).
+	+ modify CF_CFG_DEFAULTS to not use /usr as the default prefix for
+	  NetBSD.
+	+ update config.guess and config.sub from
+		http://subversions.gnu.org/cgi-bin/viewcvs/config/config/
+
+20050917
+	+ modify sed expression which computes path for /usr/lib/terminfo
+	  symbolic link in install to ensure that it does not change unexpected
+	  levels of the path (Gentoo #42336).
+	+ modify default for --disable-lp64 configure option to reduce impact
+	  on existing 64-bit builds.  Enabling the _LP64 option may change the
+	  size of chtype and mmask_t.  However, for ABI 6, it is enabled by
+	  default (report by Mike Frysinger).
+	+ add configure script check for --enable-ext-mouse, bump ABI to 6 by
+	  default if it is used.
+	+ improve configure script logic for bumping ABI to omit this if the
+	  --with-abi-version option was used.
+	+ update address for Free Software Foundation in tack's source.
+	+ correct wins_wch(), which was not marking the filler-cells of
+	  multi-column characters (cf:  20041023).
+
+20050910
+	+ modify mouse initialization to ensure that Gpm_Open() is called only
+	  once.  Otherwise GPM gets confused in its initialization of signal
+	  handlers (Debian #326709).
+
+20050903
+	+ modify logic for backspacing in a multiline form field to ensure that
+	  it works even when the preceding line is full (report by Frank van
+	  Vugt).
+	+ remove comment about BUGS section of ncurses manpage (Debian #325481)
+
+20050827
+	+ document some workarounds for shared and libtool library
+	  configurations in INSTALL (see --with-shared and --with-libtool).
+	+ modify CF_GCC_VERSION and CF_GXX_VERSION macros to accommodate
+	  cross-compilers which emit the platform name in their version
+	  message, e.g.,
+		arm-sa1100-linux-gnu-g++ (GCC) 4.0.1
+	  (report by Frank van Vugt).
+
+20050820
+	+ start updating documentation for upcoming 5.5 release.
+	+ fix to make libtool  and libtinfo work together again (cf: 20050122).
+	+ fixes to allow building traces into libtinfo
+	+ add debug trace to tic that shows if/how ncurses will write to the
+	  lower corner of a terminal's screen.
+	+ update llib-l* files.
+
+20050813
+	+ modify initializers in c++ binding to build with old versions of g++.
+	+ improve special case for 20050115 repainting fix, ensuring that if
+	  the first changed cell is not a character that the range to be
+	  repainted is adjusted to start at a character's beginning (Debian
+	  #316663).
+
+20050806
+	+ fixes to build on QNX 6.1
+	+ improve configure script checks for Intel 9.0 compiler.
+	+ remove #include's for libc.h (obsolete).
+	+ adjust ifdef's in curses.priv.h so that when cross-compiling to
+	  produce comp_hash and make_keys, no dependency on wchar.h is needed.
+	  That simplifies the build-cppflags (report by Frank van Vugt).
+	+ move modules related to key-binding into libtinfo to fix linkage
+	  problem caused by 20050430 changes to MKkeyname.sh (report by
+	  Konstantin Andreev).
+
+20050723
+	+ updates/fixes for configure script macros from vile -TD
+	+ make prism9's sgr string agree with the rest of the terminfo -TD
+	+ make vt220's sgr0 string consistent with sgr string, do this for
+	  several related cases -TD
+	+ improve translation to termcap by filtering the 'me' (sgr0) strings
+	  as in the runtime call to tgetent() (prompted by a discussion with
+	  Thomas Klausner).
+	+ improve tic check for sgr0 versus sgr(0), to help ensure that sgr0
+	  resets line-drawing.
+
+20050716
+	+ fix special cases for trimming sgr0 for hurd and vt220 (Debian
+	  #318621).
+	+ split-out _nc_trim_sgr0() from modifications made to tgetent(), to
+	  allow it to be used by tic to provide information about the runtime
+	  changes that would be made to sgr0 for termcap applications.
+	+ modify make_sed.sh to make the group-name in the NAME section of
+	  form/menu library manpage agree with the TITLE string when renaming
+	  is done for Debian (Debian #78866).
+
+20050702
+	+ modify parameter type in c++ binding for insch() and mvwinsch() to
+	  be consistent with underlying ncurses library (was char, is chtype).
+	+ modify treatment of Intel compiler to allow _GNU_SOURCE to be defined
+	  on Linux.
+	+ improve configure check for nanosleep(), checking that it works since
+	  some older systems such as AIX 4.3 have a nonworking version.
+
+20050625
+	+ update config.guess and config.sub from
+		http://subversions.gnu.org/cgi-bin/viewcvs/config/config/
+	+ modify misc/shlib to work in test-directory.
+	+ suppress $suffix in misc/run_tic.sh when cross-compiling.  This
+	  allows cross-compiles to use the host's tic program to handle the
+	  "make install.data" step.
+	+ improve description of $LINES and $COLUMNS variables in manpages
+	  (prompted by report by Dave Ulrick).
+	+ improve description of cross-compiling in INSTALL
+	+ add NCURSES-Programming-HOWTO.html by Pradeep Padala
+	  (see http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/).
+	+ modify configure script to obtain soname for GPM library (discussion
+	  with Daniel Jacobowitz).
+	+ modify configure script so that --with-chtype option will still
+	  compute the unsigned literals suffix for constants in curses.h
+	  (report by Daniel Jacobowitz:
+	+ patches from Daniel Jacobowitz:
+	  + the man_db.renames entry for tack.1 was backwards.
+	  + tack.1 had some 1m's that should have been 1M's.
+	  + the section for curs_inwstr.3 was wrong.
+
+20050619
+	+ correction to --with-chtype option (report by Daniel Jacobowitz).
+
+20050618
+	+ move build-time edit_man.sh and edit_man.sed scripts to top directory
+	  to simplify reusing them for renaming tack's manpage (prompted by a
+	  review of Debian package).
+	+ revert minor optimization from 20041030 (Debian #313609).
+	+ libtool-specific fixes, tested with libtool 1.4.3, 1.5.0, 1.5.6,
+	  1.5.10 and 1.5.18 (all work except as noted previously for the c++
+	  install using libtool 1.5.0):
+	  + modify the clean-rule in c++/Makefile.in to work with IRIX64 make
+	    program.
+	  + use $(LIBTOOL_UNINSTALL) symbol, overlooked in 20030830
+	+ add configure options --with-chtype and --with-mmask-t, to allow
+	  overriding of the non-LP64 model's use of the corresponding types.
+	+ revise test for size of chtype (and mmask_t), which always returned
+	  "long" due to an uninitialized variable (report by Daniel Jacobowitz).
+
+20050611
+	+ change _tracef's that used "%p" format for va_list values to ignore
+	  that, since on some platforms those are not pointers.
+	+ fixes for long-formats in printf's due to largefile support.
+
+20050604
+	+ fixes for termcap support:
+	  + reset pointer to _nc_curr_token.tk_name when the input stream is
+	    closed, which could point to free memory (cf: 20030215).
+	  + delink TERMTYPE data which is used by the termcap reader, so that
+	    extended names data will be freed consistently.
+	  + free pointer to TERMTYPE data in _nc_free_termtype() rather than
+	    its callers.
+	  + add some entrypoints for freeing permanently allocated data via
+	    _nc_freeall() when NO_LEAKS is defined.
+	+ amend 20041030 change to _nc_do_color to ensure that optimization is
+	  applied only when the terminal supports back_color_erase (bce).
+
+20050528
+	+ add sun-color terminfo entry -TD
+	+ correct a missing assignment in c++ binding's method
+	  NCursesPanel::UserPointer() from 20050409 changes.
+	+ improve configure check for large-files, adding check for dirent64
+	  from vile -TD
+	+ minor change to configure script to improve linker options for the
+	  Ada95 tree.
+
+20050515
+	+ document error conditions for ncurses library functions (report by
+	  Stanislav Ievlev).
+	+ regenerated html documentation for ada binding.
+	  see ftp://ftp.invisible-island.net/ncurses/patches/gnathtml
+
+20050507
+	+ regenerated html documentation for manpages.
+	+ add $(BUILD_EXEEXT) suffix to invocation of make_keys in
+	  ncurses/Makefile (Gentoo #89772).
+	+ modify c++/demo.cc to build with g++ -fno-implicit-templates option
+	  (patch by Mike Frysinger).
+	+ modify tic to filter out long extended names when translating to
+	  termcap format.  Only two characters are permissible for termcap
+	  capability names.
+
+20050430
+	+ modify terminfo entries xterm-new and rxvt to add strings for
+	  shift-, control-cursor keys.
+	+ workaround to allow c++ binding to compile with g++ 2.95.3, which
+	  has a broken implementation of static_cast<> (patch by Jeff Chua).
+	+ modify initialization of key lookup table so that if an extended
+	  capability (tic -x) string is defined, and its name begins with 'k',
+	  it will automatically be treated as a key.
+	+ modify test/keynames.c to allow for the possibility of extended
+	  key names, e.g., via define_key(), or via "tic -x".
+	+ add test/demo_termcap.c to show the contents of given entry via the
+	  termcap interface.
+
+20050423
+	+ minor fixes for vt100/vt52 entries -TD
+	+ add configure option --enable-largefile
+	+ corrected libraries used to build Ada95/gen/gen, found in testing
+	  gcc 4.0.0.
+
+20050416
+	+ update config.guess, config.sub
+	+ modify configure script check for _XOPEN_SOURCE, disable that on
+	  Darwin whose header files have problems (patch by Chris Zubrzycki).
+	+ modify form library Is_Printable_String() to use iswprint() rather
+	  than wcwidth() for determining if a character is printable.  The
+	  latter caused it to reject menu items containing non-spacing
+	  characters.
+	+ modify ncurses test program's F-test to handle non-spacing characters
+	  by combining them with a reverse-video blank.
+	+ review/fix several gcc -Wconversion warnings.
+
+20050409
+	+ correct an off-by-one error in m_driver() for mouse-clicks used to
+	  position the mouse to a particular item.
+	+ implement test/demo_menus.c
+	+ add some checks in lib_mouse to ensure SP is set.
+	+ modify C++ binding to make 20050403 changes work with the configure
+	  --enable-const option.
+
+20050403
+	+ modify start_color() to return ERR if it cannot allocate memory.
+	+ address g++ compiler warnings in C++ binding by adding explicit
+	  member initialization, assignment operators and copy constructors.
+	  Most of the changes simply preserve the existing semantics of the
+	  binding, which can leak memory, etc., but by making these features
+	  visible, it provides a framework for improving the binding.
+	+ improve C++ binding using static_cast, etc.
+	+ modify configure script --enable-warnings to add options to g++ to
+	  correspond to the gcc --enable-warnings.
+	+ modify C++ binding to use some C internal functions to make it
+	  compile properly on Solaris (and other platforms).
+
+20050327
+	+ amend change from 20050320 to limit it to configurations with a
+	  valid locale.
+	+ fix a bug introduced in 20050320 which broke the translation of
+	  nonprinting characters to uparrow form (report by Takahashi Tamotsu).
+
+20050326
+	+ add ifdef's for _LP64 in curses.h to avoid using wasteful 64-bits for
+	  chtype and mmask_t, but add configure option --disable-lp64 in case
+	  anyone used that configuration.
+	+ update misc/shlib script to account for Mac OS X (report by Michail
+	  Vidiassov).
+	+ correct comparison for wrapping multibyte characters in
+	  waddch_literal() (report by Takahashi Tamotsu).
+
+20050320
+	+ add -c and -w options to tset to allow user to suppress ncurses'
+	  resizing of the terminal emulator window in the special case where it
+	  is not able to detect the true size (report by Win Delvaux, Debian
+	  #300419).
+	+ modify waddch_nosync() to account for locale zn_CH.GBK, which uses
+	  codes 128-159 as part of multibyte characters (report by Wang
+	  WenRui, Debian #300512).
+
+20050319
+	+ modify ncurses.c 'd' test to make it work with 88-color
+	  configuration, i.e., by implementing scrolling.
+	+ improve scrolling in ncurses.c 'c' and 'C' tests, e.g., for 88-color
+	  configuration.
+
+20050312
+	+ change tracemunch to use strict checking.
+	+ modify ncurses.c 'p' test to test line-drawing within a pad.
+	+ implement environment variable NCURSES_NO_UTF8_ACS to support
+	  miscellaneous terminal emulators which ignore alternate character
+	  set escape sequences when in UTF-8 mode.
+
+20050305
+	+ change NCursesWindow::err_handler() to a virtual function (request by
+	  Steve Beal).
+	+ modify fty_int.c and fty_num.c to handle wide characters (report by
+	  Wolfgang Gutjahr).
+	+ adapt fix for fty_alpha.c to fty_alnum.c, which also handled normal
+	  and wide characters inconsistently (report by Wolfgang Gutjahr).
+	+ update llib-* files to reflect internal interface additions/changes.
+
+20050226
+	+ improve test/configure script, adding tests for _XOPEN_SOURCE, etc.,
+	  from lynx.
+	+ add aixterm-16color terminfo entry -TD
+	+ modified xterm-new terminfo entry to work with tgetent() changes -TD
+	+ extended changes in tgetent() from 20040710 to allow the substring of
+	  sgr0 which matches rmacs to be at the beginning of the sgr0 string
+	  (request by Thomas Wolff).  Wolff says the visual effect in
+	  combination with pre-20040710 ncurses is improved.
+	+ fix off-by-one in winnstr() call which caused form field validation
+	  of multibyte characters to ignore the last character in a field.
+	+ correct logic in winsch() for inserting multibyte strings; the code
+	  would clear cells after the insertion rather than push them to the
+	  right (cf: 20040228).
+	+ fix an inconsistency in Check_Alpha_Field() between normal and wide
+	  character logic (report by Wolfgang Gutjahr).
+
+20050219
+	+ fix a bug in editing wide-characters in form library: deleting a
+	  nonwide character modified the previous wide-character.
+	+ update manpage to describe NCURSES_MOUSE_VERSION 2.
+	+ correct manpage description of mouseinterval() (Debian #280687).
+	+ add a note to default_colors.3x explaining why this extension was
+	  added (Debian #295083).
+	+ add traces to panel library.
+
+20050212
+	+ improve editing of wide-characters in form library:  left/right
+	  cursor movement, and single-character deletions work properly.
+	+ disable GPM mouse support when $TERM happens to be prefixed with
+	  "xterm".  Gpm_Open() would otherwise assert that it can deal with
+	  mouse events in this case.
+	+ modify GPM mouse support so it closes the server connection when
+	  the caller disables the mouse (report by Stanislav Ievlev).
+
+20050205
+	+ add traces for callback functions in form library.
+	+ add experimental configure option --enable-ext-mouse, which defines
+	  NCURSES_MOUSE_VERSION 2, and modifies the encoding of mouse events to
+	  support wheel mice, which may transmit buttons 4 and 5.  This works
+	  with xterm and similar X terminal emulators (prompted by question by
+	  Andreas Henningsson, this is also related to Debian #230990).
+	+ improve configure macros CF_XOPEN_SOURCE and CF_POSIX_C_SOURCE to
+	  avoid redefinition warnings on cygwin.
+
+20050129
+	+ merge remaining development changes for extended colors (mostly
+	  complete, does not appear to break other configurations).
+	+ add xterm-88color.dat (part of extended colors testing).
+	+ improve _tracedump() handling of color pairs past 96.
+	+ modify return-value from start_color() to return OK if colors have
+	  already been started.
+	+ modify curs_color.3x list error conditions for init_pair(),
+	  pair_content() and color_content().
+	+ modify pair_content() to return -1 for consistency with init_pair()
+	  if it corresponds to the default-color.
+	+ change internal representation of default-color to allow application
+	  to use color number 255.  This does not affect the total number of
+	  color pairs which are allowed.
+	+ add a top-level tags rule.
+
+20050122
+	+ add a null-pointer check in wgetch() in case it is called without
+	  first calling initscr().
+	+ add some null-pointer checks for SP, which is not set by libtinfo.
+	+ modify misc/shlib to ensure that absolute pathnames are used.
+	+ modify test/Makefile.in, etc., to link test programs only against the
+	  libraries needed, e.g., omit form/menu/panel library for the ones
+	  that are curses-specific.
+	+ change SP->_current_attr to a pointer, adjust ifdef's to ensure that
+	  libtinfo.so and libtinfow.so have the same ABI.  The reason for this
+	  is that the corresponding data which belongs to the upper-level
+	  ncurses library has a different size in each model (report by
+	  Stanislav Ievlev).
+
+20050115
+	+ minor fixes to allow test-compiles with g++.
+	+ correct column value shown in tic's warnings, which did not account
+	  for leading whitespace.
+	+ add a check in _nc_trans_string() for improperly ended strings, i.e.,
+	  where a following line begins in column 1.
+	+ modify _nc_save_str() to return a null pointer on buffer overflow.
+	+ improve repainting while scrolling wide-character data (Eungkyu Song).
+
+20050108
+	+ merge some development changes to extend color capabilities.
+
+20050101
+	+ merge some development changes to extend color capabilities.
+	+ fix manpage typo (FreeBSD report docs/75544).
+	+ update config.guess, config.sub
+	> patches for configure script (Albert Chin-A-Young):
+	+ improved fix to make mbstate_t recognized on HPUX 11i (cf:
+	  20030705), making vsscanf() prototype visible on IRIX64.  Tested for
+	  on HP-UX 11i, Solaris 7, 8, 9, AIX 4.3.3, 5.2, Tru64 UNIX 4.0D, 5.1,
+	  IRIX64 6.5, Redhat Linux 7.1, 9, and RHEL 2.1, 3.0.
+	+ print the result of the --disable-home-terminfo option.
+	+ use -rpath when compiling with SGI C compiler.
+
+20041225
+	+ add trace calls to remaining public functions in form and menu
+	  libraries.
+	+ fix check for numeric digits in test/ncurses.c 'b' and 'B' tests.
+	+ fix typo in test/ncurses.c 'c' test from 20041218.
+
+20041218
+	+ revise test/ncurses.c 'c' color test to improve use for xterm-88color
+	  and xterm-256color, added 'C' test using the wide-character color_set
+	  and attr_set functions.
+
+20041211
+	+ modify configure script to work with Intel compiler.
+	+ fix an limit-check in wadd_wchnstr() which caused labels in the
+	  forms-demo to be one character short.
+	+ fix typo in curs_addchstr.3x (Jared Yanovich).
+	+ add trace calls to most functions in form and menu libraries.
+	+ update working-position for adding wide-characters when window is
+	  scrolled (prompted by related report by Eungkyu Song).
+
+20041204
+	+ replace some references on Linux to wcrtomb() which use it to obtain
+	  the length of a multibyte string with _nc_wcrtomb, since wcrtomb() is
+	  broken in glibc (see Debian #284260).
+	+ corrected length-computation in wide-character support for
+	  field_buffer().
+	+ some fixes to frm_driver.c to allow it to accept multibyte input.
+	+ modify configure script to work with Intel 8.0 compiler.
+
+20041127
+	+ amend change to setupterm() in 20030405 which would reuse the value
+	  of cur_term if the same output was selected.  This now reuses it only
+	  when setupterm() is called from tgetent(), which has no notion of
+	  separate SCREENs.  Note that tgetent() must be called after initscr()
+	  or newterm() to use this feature (Redhat #140326).
+	+ add a check in CF_BUILD_CC macro to ensure that developer has given
+	  the --with-build-cc option when cross-compiling (report by Alexandre
+	  Campo).
+	+ improved configure script checks for _XOPEN_SOURCE and
+	  _POSIX_C_SOURCE (fix for IRIX 5.3 from Georg Schwarz, _POSIX_C_SOURCE
+	  updates from lynx).
+	+ cosmetic fix to test/gdc.c to recolor the bottom edge of the box
+	  for consistency (comment by Dan Nelson).
+
+20041120
+	+ update wsvt25 terminfo entry -TD
+	+ modify test/ins_wide.c to test all flavors of ins_wstr().
+	+ ignore filler-cells in wadd_wchnstr() when adding a cchar_t array
+	  which consists of multi-column characters, since this function
+	  constructs them (cf: 20041023).
+	+ modify winnstr() to return multibyte character strings for the
+	  wide-character configuration.
+
+20041106
+	+ fixes to make slk_set() and slk_wset() accept and store multibyte
+	  or multicolumn characters.
+
+20041030
+	+ improve color optimization a little by making _nc_do_color() check
+	  if the old/new pairs are equivalent to the default pair 0.
+	+ modify assume_default_colors() to not require that
+	  use_default_colors() be called first.
+
+20041023
+	+ modify term_attrs() to use termattrs(), add the extended attributes
+	  such as enter_horizontal_hl_mode for WA_HORIZONTAL to term_attrs().
+	+ add logic in waddch_literal() to clear orphaned cells when one
+	  multi-column character partly overwrites another.
+	+ improved logic for clearing cells when a multi-column character
+	  must be wrapped to a new line.
+	+ revise storage of cells for multi-column characters to correct a
+	  problem with repainting.  In the old scheme, it was possible for
+	  doupdate() to decide that only part of a multi-column character
+	  should be repainted since the filler cells stored only an attribute
+	  to denote them as fillers, rather than the character value and the
+	  attribute.
+
+20041016
+	+ minor fixes for traces.
+	+ add SP->_screen_acs_map[], used to ensure that mapping of missing
+	  line-drawing characters is handled properly.  For example, ACS_DARROW
+	  is absent from xterm-new, and it was coincidentally displayed the
+	  same as ACS_BTEE.
+
+20041009
+	+ amend 20021221 workaround for broken acs to reset the sgr, rmacs
+	  and smacs strings as well.  Also modify the check for screen's
+	  limitations in that area to allow the multi-character shift-in
+	  and shift-out which seem to work.
+	+ change GPM initialization, using dl library to load it dynamically
+	  at runtime (Debian #110586).
+
+20041002
+	+ correct logic for color pair in setcchar() and getcchar() (patch by
+	  Marcin 'Qrczak' Kowalczyk).
+	+ add t/T commands to ncurses b/B tests to allow a different color to
+	  be tested for the attrset part of the test than is used in the
+	  background color.
+
+20040925
+	+ fix to make setcchar() to work when its wchar_t* parameter is
+	  pointing to a string which contains more data than can be converted.
+	+ modify wget_wstr() and example in ncurses.c to work if wchar_t and
+	  wint_t are different sizes (report by Marcin 'Qrczak' Kowalczyk).
+
+20040918
+	+ remove check in wget_wch() added to fix an infinite loop, appears to
+	  have been working around a transitory glibc bug, and interferes
+	  with normal operation (report by Marcin 'Qrczak' Kowalczyk).
+	+ correct wadd_wch() and wecho_wch(), which did not pass the rendition
+	  information (report by Marcin 'Qrczak' Kowalczyk).
+	+ fix aclocal.m4 so that the wide-character version of ncurses gets
+	  compiled as libncursesw.5.dylib, instead of libncurses.5w.dylib
+	  (adapted from patch by James J Ramsey).
+	+ change configure script for --with-caps option to indicate that it
+	  is no longer experimental.
+	+ change configure script to reflect the fact that --enable-widec has
+	  not been "experimental" since 5.3 (report by Bruno Lustosa).
+
+20040911
+	+ add 'B' test to ncurses.c, to exercise some wide-character functions.
+
+20040828
+	+ modify infocmp -i option to match 8-bit controls against its table
+	  entries, e.g., so it can analyze the xterm-8bit entry.
+	+ add morphos terminfo entry, improve amiga-8bit entry (Pavel Fedin).
+	+ correct translation of "%%" in terminfo format to termcap, e.g.,
+	  using "tic -C" (Redhat #130921).
+	+ modified configure script CF_XOPEN_SOURCE macro to ensure that if
+	  it defines _POSIX_C_SOURCE, that it defines it to a specific value
+	  (comp.os.stratus newsgroup comment).
+
+20040821
+	+ fixes to build with Ada95 binding with gnat 3.4 (all warnings are
+	  fatal, and gnat does not follow the guidelines for pragmas).
+	  However that did find a coding error in Assume_Default_Colors().
+	+ modify several terminfo entries to ensure xterm mouse and cursor
+	  visibility are reset in rs2 string:  hurd, putty, gnome,
+	  konsole-base, mlterm, Eterm, screen (Debian #265784, Debian #55637).
+	  The xterm entries are left alone - old ones for compatibility, and
+	  the new ones do not require this change. -TD
+
+20040814
+	+ fake a SIGWINCH in newterm() to accommodate buggy terminal emulators
+	  and window managers (Debian #265631).
+	> terminfo updates -TD
+	+ remove dch/dch1 from rxvt because they are implemented inconsistently
+	  with the common usage of bce/ech
+	+ remove khome from vt220 (vt220's have no home key)
+	+ add rxvt+pcfkeys
+
+20040807
+	+ modify test/ncurses.c 'b' test, adding v/V toggles to cycle through
+	  combinations of video attributes so that for instance bold and
+	  underline can be tested.  This made the legend too crowded, added
+	  a help window as well.
+	+ modify test/ncurses.c 'b' test to cycle through default colors if
+	  the -d option is set.
+	+ update putty terminfo entry (Robert de Bath).
+
+20040731
+	+ modify test/cardfile.c to allow it to read more data than can be
+	  displayed.
+	+ correct logic in resizeterm.c which kept it from processing all
+	  levels of window hierarchy (reports by Folkert van Heusden,
+	  Chris Share).
+
+20040724
+	+ modify "tic -cv" to ignore delays when comparing strings.  Also
+	  modify it to ignore a canceled sgr string, e.g., for terminals which
+	  cannot properly combine attributes in one control sequence.
+	+ corrections for gnome and konsole entries (Redhat #122815, patch by
+	  Hans de Goede)
+	> terminfo updates -TD

+	+ correct tsl string in kterm
+
+20040711
+	+ add configure option --without-xterm-new
+
+20040710
+	+ add check in wget_wch() for printable bytes that are not part of a
+	  multibyte character.
+	+ modify wadd_wchnstr() to render text using window's background
+	  attributes.
+	+ improve tic's check to compare sgr and sgr0.
+	+ fix c++ directory's .cc.i rule.
+	+ modify logic in tgetent() which adjusts the termcap "me" string
+	  to work with ISO-2022 string used in xterm-new (cf: 20010908).
+	+ modify tic's check for conflicting function keys to omit that if
+	  converting termcap to termcap format.
+	+ add -U option to tic and infocmp.
+	+ add rmam/smam to linux terminfo entry (Trevor Van Bremen)

+	  (report/patch by Tony Li).
+	+ fix a missing nul check in set_field_buffer() from 20040508 changes.
+	> terminfo updates -TD

+	  cross-compiling from a separate directory tree (report/patch by
+	  Dan Engel).
+	+ modify is_term_resized() to ensure that window sizes are nonzero,
+	  as documented in the manpage (report by Ian Collier).
+	+ modify CF_XOPEN_SOURCE configure macro to make Hurd port build
+	  (Debian #249214, report/patch by Jeff Bailey).
+	+ configure-script mods from xterm, e.g., updates to CF_ADD_CFLAGS
+	+ update config.guess, config.sub
+	> terminfo updates -TD
+	  + add mlterm
+	  + add xterm-xf86-v44
+	  + modify xterm-new aka xterm-xfree86 to accommodate luit, which
+	    relies on G1 being used via an ISO-2022 escape sequence (report by
+	    Juliusz Chroboczek)
+	  + add 'hurd' entry
+
+20040619
+	+ reconsidered winsnstr(), decided after comparing other
+	  implementations that wrapping is an X/Open documentation error.
+	+ modify test/inserts.c to test all flavors of insstr().
+
+20040605
+	+ add setlocale() calls to a few test programs which may require it:
+	  demo_forms.c, filter.c, ins_wide.c, inserts.c
+	+ correct a few misspelled function names in ncurses-intro.html (report
+	  by Tony Li).
+	+ correct internal name of key_defined() manpage, which conflicted with
+	  define_key().
+
+20040529
+	+ correct size of internal pad used for holding wide-character
+	  field_buffer() results.
+	+ modify data_ahead() to work with wide-characters.
+
+20040522
+	+ improve description of terminfo if-then-else expressions (suggested
+	  by Arne Thomassen).
+	+ improve test/ncurses.c 'd' test, allow it to use external file for
+	  initial palette (added xterm-16color.dat and linux-color.dat), and
+	  reset colors to the initial palette when starting/ending the test.
+	+ change limit-check in init_color() to allow r/g/b component to
+	  reach 1000 (cf: 20020928).
+
+20040516
+	+ modify form library to use cchar_t's rather than char's in the

+	  (adapted from patch by Philipp Tomsich).
+	+ add "-x" option to infocmp like tic's "-x", for use in "-F"
+	  comparisons.  This modifies infocmp to only report extended
+	  capabilities if the -x option is given, making this more consistent
+	  with tic.  Some scripts may break, since infocmp previous gave this
+	  information without an option.
+	+ modify termcap-parsing to retain 2-character aliases at the beginning
+	  of an entry if the "-x" option is used in tic.
+
+20040424
+	+ minor compiler-warning and test-program fixes.
+
+20040417
+	+ modify tic's missing-sgr warning to apply to terminfo only.
+	+ free some memory leaks in tic.
+	+ remove check in post_menu() that prevented menus from extending
+	  beyond the screen (request by Max J. Werner).
+	+ remove check in newwin() that prevents allocating windows
+	  that extend beyond the screen.  Solaris curses does this.
+	+ add ifdef in test/color_set.c to allow it to compile with older
+	  curses.
+	+ add napms() calls to test/dots.c to make it not be a CPU hog.
+
+20040403
+	+ modify unctrl() to return null if its parameter does not correspond
+	  to an unsigned char.
+	+ add some limit-checks to guard isprint(), etc., from being used on
+	  values that do not fit into an unsigned char (report by Sami Farin).
+
+20040328
+	+ fix a typo in the _nc_get_locale() change.
+
+20040327
+	+ modify _nc_get_locale() to use setlocale() to query the program's
+	  current locale rather than using getenv().  This fixes a case in tin
+	  which relies on legacy treatment of 8-bit characters when the locale
+	  is not initialized (reported by Urs Jansen).
+	+ add sgr string to screen's and rxvt's terminfo entries -TD.
+	+ add a check in tic for terminfo entries having an sgr0 but no sgr
+	  string.  This confuses Tru64 and HPUX curses when combined with
+	  color, e.g., making them leave line-drawing characters in odd places.
+	+ correct casts used in ABSENT_BOOLEAN, CANCELLED_BOOLEAN, matches the
+	  original definitions used in Debian package to fix PowerPC bug before
+	  20030802 (Debian #237629).
+
+20040320
+	+ modify PutAttrChar() and PUTC() macro to improve use of
+	  A_ALTCHARSET attribute to prevent line-drawing characters from
+	  being lost in situations where the locale would otherwise treat the
+	  raw data as nonprintable (Debian #227879).
+
+20040313
+	+ fix a redefinition of CTRL() macro in test/view.c for AIX 5.2 (report
+	  by Jim Idle).
+	+ remove ".PP" after ".SH NAME" in a few manpages; this confuses
+	  some apropos script (Debian #237831).
+
+20040306
+	+ modify ncurses.c 'r' test so editing commands, like inserted text,
+	  set the field background, and the state of insert/overlay editing
+	  mode is shown in that test.
+	+ change syntax of dummy targets in Ada95 makefiles to work with pmake.
+	+ correct logic in test/ncurses.c 'b' for noncolor terminals which
+	  did not recognize a quit-command (cf: 20030419).
+
+20040228
+	+ modify _nc_insert_ch() to allow for its input to be part of a
+	  multibyte string.
+	+ split out lib_insnstr.c, to prepare to rewrite it.  X/Open states
+	  that this function performs wrapping, unlike all of the other
+	  insert-functions.  Currently it does not wrap.
+	+ check for nl_langinfo(CODESET), use it if available (report by
+	  Stanislav Ievlev).
+	+ split-out CF_BUILD_CC macro, actually did this for lynx first.
+	+ fixes for configure script CF_WITH_DBMALLOC and CF_WITH_DMALLOC,
+	  which happened to work with bash, but not with Bourne shell (report
+	  by Marco d'Itri via tin-dev).
+
+20040221
+	+ some changes to adapt the form library to wide characters, incomplete
+	  (request by Mike Aubury).
+	+ add symbol to curses.h which can be used to suppress include of
+	  stdbool.h, e.g.,
+		#define NCURSES_ENABLE_STDBOOL_H 0
+		#include <curses.h>
+	  (discussion on XFree86 mailing list).
+
+20040214
+	+ modify configure --with-termlib option to accept a value which sets
+	  the name of the terminfo library.  This would allow a packager to
+	  build libtinfow.so renamed to coincide with libtinfo.so (discussion
+	  with Stanislav Ievlev).
+	+ improve documentation of --with-install-prefix, --prefix and
+	  $(DESTDIR) in INSTALL (prompted by discussion with Paul Lew).
+	+ add configure check if the compiler can use -c -o options to rename
+	  its output file, use that to omit the 'cd' command which was used to
+	  ensure object files are created in a separate staging directory
+	  (prompted by comments by Johnny Wezel, Martin Mokrejs).
+
+20040208 5.4 release for upload to ftp.gnu.org
+	+ update TO-DO.
+
+20040207 pre-release
+	+ minor fixes to _nc_tparm_analyze(), i.e., do not count %i as a param,
+	  and do not count %d if it follows a %p.
+	+ correct an inconsistency between handling of codes in the 128-255
+	  range, e.g., as illustrated by test/ncurses.c f/F tests.  In POSIX
+	  locale, the latter did not show printable results, while the former
+	  did.
+	+ modify MKlib_gen.sh to compensate for broken C preprocessor on Mac
+	  OS X, which alters "%%" to "% % " (report by Robert Simms, fix
+	  verified by Scott Corscadden).
+
+20040131 pre-release
+	+ modify SCREEN struct to align it between normal/wide curses flavors
+	  to simplify future changes to build a single version of libtinfo
+	  (patch by Stanislav Ievlev).
+	+ document handling of carriage return by addch() in manpage.
+	+ document special features of unctrl() in manpage.
+	+ documented interface changes in INSTALL.
+	+ corrected control-char test in lib_addch.c to account for locale
+	  (Debian #230335, cf: 971206).
+	+ updated test/configure.in to use AC_EXEEXT and AC_OBJEXT.
+	+ fixes to compile Ada95 binding with Debian gnat 3.15p-4 package.
+	+ minor configure-script fixes for older ports, e.g., BeOS R4.5.
+
+20040125 pre-release
+	+ amend change to PutAttrChar() from 20030614 which computed the number
+	  of cells for a possibly multi-cell character.  The 20030614 change
+	  forced the cell to a blank if the result from wcwidth() was not
+	  greater than zero.  However, wcwidth() called for parameters in the
+	  range 128-255 can give this return value.  The logic now simply
+	  ensures that the number of cells is greater than zero without
+	  modifying the displayed value.
+
+20040124 pre-release
+	+ looked good for 5.4 release for upload to ftp.gnu.org (but see above)
+	+ modify configure script check for ranlib to use AC_CHECK_TOOL, since
+	  that works better for cross-compiling.
+
+20040117 pre-release
+	+ modify lib_get_wch.c to prefer mblen/mbtowc over mbrlen/mbrtowc to
+	  work around core dump in Solaris 8's locale support, e.g., for
+	  zh_CN.GB18030 (report by Saravanan Bellan).
+	+ add includes for <stdarg.h> and <stdio.h> in configure script macro
+	  to make <wchar.h> check work with Tru64 4.0d.
+	+ add terminfo entry for U/Win -TD
+	+ add terminfo entries for SFU aka Interix aka OpenNT (Federico
+	  Bianchi).
+	+ modify tput's error messages to prefix them with the program name
+	  (report by Vincent Lefevre, patch by Daniel Jacobowitz (see Debian
+	  #227586)).
+	+ correct a place in tack where exit_standout_mode was used instead of
+	  exit_attribute_mode (patch by Jochen Voss (see Debian #224443)).
+	+ modify c++/cursesf.h to use const in the Enumeration_Field method.
+	+ remove an ambiguous (actually redundant) method from c++/cursesf.h
+	+ make $HOME/.terminfo update optional (suggested by Stanislav Ievlev).
+	+ improve sed script which extracts libtool's version in the
+	  CF_WITH_LIBTOOL macro.
+	+ add ifdef'd call to AC_PROG_LIBTOOL to CF_WITH_LIBTOOL macro (to
+	  simplify local patch for Albert Chin-A-Young)..
+	+ add $(CXXFLAGS) to link command in c++/Makefile.in (adapted from
+	  patch by Albert Chin-A-Young)..
+	+ fix a missing substitution in configure.in for "$target" needed for
+	  HPUX .so/.sl case.
+	+ resync CF_XOPEN_SOURCE configure macro with lynx; fixes IRIX64 and
+	  NetBSD 1.6 conflicts with _XOPEN_SOURCE.
+	+ make check for stdbool.h more specific, to ensure that including it
+	  will actually define/declare bool for the configured compiler.
+	+ rewrite ifdef's in curses.h relating NCURSES_BOOL and bool.  The
+	  intention of that is to #define NCURSES_BOOL as bool when the
+	  compiler declares bool, and to #define bool as NCURSES_BOOL when it
+	  does not (reported by Jim Gifford, Sam Varshavchik, cf: 20031213).
+
+20040110 pre-release
+	+ change minor version to 4, i.e., ncurses 5.4
+	+ revised/improved terminfo entries for tvi912b, tvi920b (Benjamin C W
+	  Sittler).
+	+ simplified ncurses/base/version.c by defining the result from the
+	  configure script rather than using sprintf (suggested by Stanislav
+	  Ievlev).
+	+ remove obsolete casts from c++/cursesw.h (reported by Stanislav
+	  Ievlev).
+	+ modify configure script so that when configuring for termlib, programs
+	  such as tic are not linked with the upper-level ncurses library
+	  (suggested by Stanislav Ievlev).
+	+ move version.c from ncurses/base to ncurses/tinfo to allow linking
+	  of tic, etc., using libtinfo (suggested by Stanislav Ievlev).
+
+20040103
+	+ adjust -D's to build ncursesw on OpenBSD.
+	+ modify CF_PROG_EXT to make OS/2 build with EXEEXT.
+	+ add pecho_wchar().
+	+ remove <wctype.h> include from lib_slk_wset.c which is not needed (or
+	  available) on older platforms.
+
+20031227
+	+ add -D's to build ncursew on FreeBSD 5.1.
+	+ modify shared library configuration for FreeBSD 4.x/5.x to add the
+	  soname information (request by Marc Glisse).
+	+ modify _nc_read_tic_entry() to not use MAX_ALIAS, but PATH_MAX only
+	  for limiting the length of a filename in the terminfo database.
+	+ modify termname() to return the terminal name used by setupterm()
+	  rather than $TERM, without truncating to 14 characters as documented
+	  by X/Open (report by Stanislav Ievlev, cf:  970719).
+	+ re-add definition for _BSD_TYPES, lost in merge (cf: 20031206).
+
+20031220
+	+ add configure option --with-manpage-format=catonly to address
+	  behavior of BSDI, allow install of man+cat files on NetBSD, whose
+	  behavior has diverged by requiring both to be present.
+	+ remove leading blanks from comment-lines in manlinks.sed script to
+	  work with Tru64 4.0d.
+	+ add screen.linux terminfo entry (discussion on mutt-users mailing
+	  list).
+
+20031213
+	+ add a check for tic to flag missing backslashes for termcap
+	  continuation lines.  ncurses reads the whole entry, but termcap
+	  applications do not.
+	+ add configure option "--with-manpage-aliases" extending
+	  "--with-manpage-aliases" to provide the option of generating ".so"
+	  files rather than symbolic links for manpage aliases.
+	+ add bool definition in include/curses.h.in for configurations with no
+	  usable C++ compiler (cf: 20030607).
+	+ fix pathname of SigAction.h for building with --srcdir (reported by
+	  Mike Castle).
+
+20031206
+	+ folded ncurses/base/sigaction.c into includes of ncurses/SigAction.h,
+	  since that header is used only within ncurses/tty/lib_tstp.c, for
+	  non-POSIX systems (discussion with Stanislav Ievlev).
+	+ remove obsolete _nc_outstr() function (report by Stanislav Ievlev
+	  <inger@altlinux.org>).
+	+ add test/background.c and test/color_set.c
+	+ modify color_set() function to work with color pair 0 (report by
+	  George Andreou <gbandreo@tem.uoc.gr>).
+	+ add configure option --with-trace, since defining TRACE seems too
+	  awkward for some cases.
+	+ remove a call to _nc_free_termtype() from read_termtype(), since the
+	  corresponding buffer contents were already zeroed by a memset (cf:
+	  20000101).
+	+ improve configure check for _XOPEN_SOURCE and related definitions,
+	  adding special cases for Solaris' __EXTENSIONS__ and FreeBSD's
+	  __BSD_TYPES (reports by Marc Glisse <marc.glisse@normalesup.org>).
+	+ small fixes to compile on Solaris and IRIX64 using cc.
+	+ correct typo in check for pre-POSIX sort options in MKkey_defs.sh
+	  (cf: 20031101).
+
+20031129
+	+ modify _nc_gettime() to avoid a problem with arithmetic on unsigned
+	  values (Philippe Blain).
+	+ improve the nanosleep() logic in napms() by checking for EINTR and
+	  restarting (Philippe Blain).
+	+ correct expression for "%D" in lib_tgoto.c (Juha Jarvi
+	  <mooz@welho.com>).
+
+20031122
+	+ add linux-vt terminfo entry (Andrey V Lukyanov <land@long.yar.ru>).
+	+ allow "\|" escape in terminfo; tic should not warn about this.
+	+ save the full pathname of the trace-file the first time it is opened,
+	  to avoid creating it in different directories if the application
+	  opens and closes it while changing its working directory.
+	+ modify configure script to provide a non-empty default for
+	  $BROKEN_LINKER
+
+20031108
+	+ add DJGPP to special case of DOS-style drive letters potentially
+	  appearing in TERMCAP environment variable.
+	+ fix some spelling in comments (reports by Jason McIntyre, Jonathon
+	  Gray).
+	+ update config.guess, config.sub
+
+20031101
+	+ fix a memory leak in error-return from setupterm() (report by
+	  Stanislav Ievlev <inger@altlinux.org>).
+	+ use EXEEXT and OBJEXT consistently in makefiles.
+	+ amend fixes for cross-compiling to use separate executable-suffix
+	  BUILD_EXEEXT (cf: 20031018).
+	+ modify MKkey_defs.sh to check for sort utility that does not
+	  recognize key options, e.g., busybox (report by Peter S Mazinger
+	  <ps.m@gmx.net>).
+	+ fix potential out-of-bounds indexing in _nc_infotocap() (found by
+	  David Krause using some of the new malloc debugging features
+	  under OpenBSD, patch by Ted Unangst).
+	+ modify CF_LIB_SUFFIX for Itanium releases of HP-UX, which use a
+	  ".so" suffix (patch by Jonathan Ward <Jonathan.Ward@hp.com>).
+
+20031025
+	+ update terminfo for xterm-xfree86 -TD
+	+ add check for multiple "tc=" clauses in a termcap to tic.
+	+ check for missing op/oc in tic.
+	+ correct _nc_resolve_uses() and _nc_merge_entry() to allow infocmp and
+	  tic to show cancelled capabilities.  These functions were ignoring
+	  the state of the target entry, which should be untouched if cancelled.
+	+ correct comment in tack/output.c (Debian #215806).
+	+ add some null-pointer checks to lib_options.c (report by Michael
+	  Bienia).
+	+ regenerated html documentation.
+	+ correction to tar-copy.sh, remove a trap command that resulted in
+	  leaving temporary files (cf: 20030510).
+	+ remove contact/maintainer addresses for Juergen Pfeifer (his request).
+
+20031018
+	+ updated test/configure to reflect changes for libtool (cf: 20030830).
+	+ fix several places in tack/pad.c which tested and used the parameter-
+	  and parameterless strings inconsistently, i.e., in pad_rin(),
+	  pad_il(), pad_indn() and pad_dl() (Debian #215805).
+	+ minor fixes for configure script and makefiles to cleanup executables
+	  generated when cross-compiling for DJGPP.
+	+ modify infocmp to omit check for $TERM for operations that do not
+	  require it, e.g., "infocmp -e" used to build fallback list (report by
+	  Egmont Koblinger).
+
+20031004
+	+ add terminfo entries for DJGPP.
+	+ updated note about maintainer in ncurses-intro.html
+
+20030927
+	+ update terminfo entries for gnome terminal.
+	+ modify tack to reset colors after each color test, correct a place
+	  where exit_standout_mode was used instead of exit_attribute_mode.
+	+ improve tack's bce test by making it set colors other than black
+	  on white.
+	+ plug a potential recursion between napms() and _nc_timed_wait()
+	  (report by Philippe Blain).
+
+20030920
+	+ add --with-rel-version option to allow workaround to allow making
+	  libtool on Darwin generate the "same" library names as with the
+	  --with-shared option.  The Darwin ld program does not work well
+	  with a zero as the minor-version value (request by Chris Zubrzycki).
+	+ modify CF_MIXEDCASE_FILENAMES macro to work with cross-compiling.
+	+ modify tack to allow it to run from fallback terminfo data.
+	> patch by Philippe Blain:
+	+ improve PutRange() by adjusting call to EmitRange() and corresponding
+	  return-value to not emit unchanged characters on the end of the
+	  range.
+	+ improve a check for changed-attribute by exiting a loop when the
+	  change is found.
+	+ improve logic in TransformLine(), eliminating a duplicated comparison
+	  in the clr_bol logic.
+
+20030913
+	> patch by Philippe Blain:
+	+ in ncurses/tty/lib_mvcur.c,
+	  move the label 'nonlocal' just before the second gettimeofday() to
+	  be able to compute the diff time when 'goto nonlocal' used.
+	  Rename 'msec' to 'microsec' in the debug-message.
+	+ in ncurses/tty/lib_mvcur.c,
+	  Use _nc_outch() in carriage return/newline movement instead of
+	  putchar() which goes to stdout.  Move test for xold>0 out of loop.
+	+ in ncurses/tinfo/setbuf.c,
+	  Set the flag SP->_buffered at the end of operations when all has been
+	  successful (typeMalloc can fail).
+	+ simplify NC_BUFFERED macro by moving check inside _nc_setbuf().
+
+20030906
+	+ modify configure script to avoid using "head -1", which does not
+	  work if POSIXLY_CORRECT (sic) is set.
+	+ modify run_tic.in to avoid using wrong shared libraries when
+	  cross-compiling (Dan Kegel).
+
+20030830
+	+ alter configure script help message to make it clearer that
+	  --with-build-cc does not specify a cross-compiler (suggested by Dan
+	  Kegel <dank@kegel.com>).
+	+ modify configure script to accommodate libtool 1.5, as well as add an
+	  parameter to the "--with-libtool" option which can specify the
+	  pathname of libtool (report by Chris Zubrzycki).  We note that
+	  libtool 1.5 has more than one bug in its C++ support, so it is not
+	  able to install libncurses++, for instance, if $DESTDIR or the option
+	  --with-install-prefix is used.
+
+20030823
+	> patch by Philippe Blain:
+	+ move assignments to SP->_cursrow, SP->_curscol into online_mvcur().
+	+ make baudrate computation in delay_output() consistent with the
+	  assumption in _nc_mvcur_init(), i.e., a byte is 9 bits.
+
+20030816
+	+ modify logic in waddch_literal() to take into account zh_TW.Big5
+	  whose multibyte sequences may contain "printable" characters, e.g.,
+	  a "g" in the sequence "\247g" (Debian #204889, cf: 20030621).
+	+ improve storage used by _nc_safe_strcpy() by ensuring that the size
+	  is reset based on the initialization call, in case it were called
+	  after other strcpy/strcat calls (report by Philippe Blain).
+	> patch by Philippe Blain:
+	+ remove an unused ifdef for REAL_ATTR & WANT_CHAR
+	+ correct a place where _cup_cost was used rather than _cuu_cost
+
+20030809
+	+ fix a small memory leak in _nc_free_termtype().
+	+ close trace-file if trace() is called with a zero parameter.
+	+ free memory allocated for soft-key strings, in delscreen().
+	+ fix an allocation size in safe_sprintf.c for the "*" format code.
+	+ correct safe_sprintf.c to not return a null pointer if the format
+	  happens to be an empty string.  This applies to the "configure
+	  --enable-safe-sprintf" option (Redhat #101486).
+
+20030802
+	+ modify casts used for ABSENT_BOOLEAN and CANCELLED_BOOLEAN (report by
+	  Daniel Jacobowitz).
+	> patch by Philippe Blain:
+	+ change padding for change_scroll_region to not be proportional to
+	  the size of the scroll-region.
+	+ correct error-return in _nc_safe_strcat().
+
+20030726
+	+ correct limit-checks in _nc_scroll_window() (report and test-case by
+	  Thomas Graf <graf@dms.at> cf: 20011020).
+	+ re-order configure checks for _XOPEN_SOURCE to avoid conflict with
+	  _GNU_SOURCE check.
+
+20030719
+	+ use clr_eol in preference to blanks for bce terminals, so select and
+	  paste will have fewer trailing blanks, e.g., when using xterm
+	  (request by Vincent Lefevre).
+	+ correct prototype for wunctrl() in manpage.
+	+ add configure --with-abi-version option (discussion with Charles
+	  Wilson).
+	> cygwin changes from Charles Wilson:
+	  + aclocal.m4: on cygwin, use autodetected prefix for import
+	    and static lib, but use "cyg" for DLL.
+	  + include/ncurses_dll.h: correct the comments to reflect current
+	    status of cygwin/mingw port.  Fix compiler warning.
+	  + misc/run_tic.in: ensure that tic.exe can find the uninstalled
+	    DLL, by adding the lib-directory to the PATH variable.
+	  + misc/terminfo.src (nxterm|xterm-color): make xterm-color
+	    primary instead of nxterm, to match XFree86's xterm.terminfo
+	    usage and to prevent circular links.
+	    (rxvt): add additional codes from rxvt.org.
+	    (rxvt-color): new alias
+	    (rxvt-xpm): new alias
+	    (rxvt-cygwin): like rxvt, but with special acsc codes.
+	    (rxvt-cygwin-native): ditto.  rxvt may be run under XWindows, or
+	    with a "native" MSWin GUI.	Each takes different acsc codes,
+	    which are both different from the "normal" rxvt's acsc.
+	    (cygwin): cygwin-in-cmd.exe window.	 Lots of fixes.
+	    (cygwinDBG): ditto.
+	  + mk-1st.awk: use "cyg" for the DLL prefix, but "lib" for import
+	    and static libs.
+
+20030712
+	+ update config.guess, config.sub
+	+ add triples for configuring shared libraries with the Debian
+	  GNU/FreeBSD packages (patch by Robert Millan <zeratul2@wanadoo.es>).
+
+20030705
+	+ modify CF_GCC_WARNINGS so it only applies to gcc, not g++.  Some
+	  platforms have installed g++ along with the native C compiler, which
+	  would not accept gcc warning options.
+	+ add -D_XOPEN_SOURCE=500 when configuring with --enable-widec, to
+	  get mbstate_t declaration on HPUX 11.11 (report by David Ellement).
+	+ add _nc_pathlast() to get rid of casts in _nc_basename() calls.
+	+ correct a sign-extension in wadd_wch() and wecho_wchar() from
+	  20030628 (report by Tomohiro Kubota).
+	+ work around omission of btowc() and wctob() from wide-character
+	  support (sic) in NetBSD 1.6 using mbtowc() and wctomb() (report by
+	  Gabor Z Papp).
+	+ add portability note to curs_get_wstr.3x (Debian #199957).
+
+20030628
+	+ rewrite wadd_wch() and wecho_wchar() to call waddch() and wechochar()
+	  respectively, to avoid calling waddch_noecho() with wide-character
+	  data, since that function assumes its input is 8-bit data.
+	  Similarly, modify waddnwstr() to call wadd_wch().
+	+ remove logic from waddnstr() which transformed multibyte character
+	  strings into wide-characters.  Rewrite of waddch_literal() from
+	  20030621 assumes its input is raw multibyte data rather than wide
+	  characters (report by Tomohiro Kubota).
+
+20030621
+	+ write getyx() and related 2-return macros in terms of getcury(),
+	  getcurx(), etc.
+	+ modify waddch_literal() in case an application passes bytes of a
+	  multibyte character directly to waddch().  In this case, waddch()
+	  must reassemble the bytes into a wide-character (report by Tomohiro
+	  Kubota <kubota@debian.org>).
+
+20030614
+	+ modify waddch_literal() in case a multibyte value occupies more than
+	  two cells.
+	+ modify PutAttrChar() to compute the number of character cells that
+	  are used in multibyte values.  This fixes a problem displaying
+	  double-width characters (report/test by Mitsuru Chinen
+	  <mchinen@yamato.ibm.com>).
+	+ add a null-pointer check for result of keyname() in _tracechar()
+	+ modify _tracechar() to work around glibc sprintf bug.
+
+20030607
+	+ add a call to setlocale() in cursesmain.cc, making demo display
+	  properly in a UTF-8 locale.
+	+ add a fallback definition in curses.priv.h for MB_LEN_MAX (prompted
+	  by discussion with Gabor Z Papp).
+	+ use macros NCURSES_ACS() and NCURSES_WACS() to hide cast needed to
+	  appease -Wchar-subscript with g++ 3.3 (Debian #195732).
+	+ fix a redefinition of $RANLIB in the configure script when libtool
+	  is used, which broke configure on Mac OS X (report by Chris Zubrzycki
+	  <beren@mac.com>).
+	+ simplify ifdef for bool declaration in curses.h.in (suggested by
+	  Albert Chin-A-Young).
+	+ remove configure script check to allow -Wconversion for older
+	  versions of gcc (suggested by Albert Chin-A-Young).
+
+20030531
+	+ regenerated html manpages.
+	+ modify ifdef's in curses.h.in that disabled use of __attribute__()
+	  for g++, since recent versions implement the cases which ncurses uses
+	  (Debian #195230).
+	+ modify _nc_get_token() to handle a case where an entry has no
+	  description, and capabilities begin on the same line as the entry
+	  name.
+	+ fix a typo in ncurses_dll.h reported by gcc 3.3.
+	+ add an entry for key_defined.3x to man_db.renames.
+
+20030524
+	+ modify setcchar() to allow converting control characters to complex
+	  characters (report/test by Mitsuru Chinen <mchinen@yamato.ibm.com>).
+	+ add tkterm entry -TD
+	+ modify parse_entry.c to allow a terminfo entry with a leading
+	  2-character name (report by Don Libes).
+	+ corrected acsc in screen.teraterm, which requires a PC-style mapping.
+	+ fix trace statements in read_entry.c to use lseek() rather than
+	  tell().
+	+ fix signed/unsigned warnings from Sun's compiler (gcc should give
+	  these warnings, but it is unpredictable).
+	+ modify configure script to omit -Winline for gcc 3.3, since that
+	  feature is broken.
+	+ modify manlinks.sed to add a few functions that were overlooked since
+	  they return function pointers:  field_init, field_term, form_init,
+	  form_term, item_init, item_term, menu_init and menu_term.
+
+20030517
+	+ prevent recursion in wgetch() via wgetnstr() if the connection cannot
+	  be switched between cooked/raw modes because it is not a TTY (report
+	  by Wolfgang Gutjahr <gutw@knapp.com>).
+	+ change parameter of define_key() and key_defined() to const (prompted
+	  by Debian #192860).
+	+ add a check in test/configure for ncurses extensions, since there
+	  are some older versions, etc., which would not compile with the
+	  current test programs.
+	+ corrected demo in test/ncurses.c of wgetn_wstr(), which did not
+	  convert wchar_t string to multibyte form before printing it.
+	+ corrections to lib_get_wstr.c:
+	  + null-terminate buffer passed to setcchar(), which occasionally
+	    failed.
+	  + map special characters such as erase- and kill-characters into
+	    key-codes so those will work as expected even if they are not
+	    mentioned in the terminfo.
+	+ modify PUTC() and Charable() macros to make wide-character line
+	  drawing work for POSIX locale on Linux console (cf: 20021221).
+
+20030510
+	+ make typography for program options in manpages consistent (report
+	  by Miloslav Trmac <mitr@volny.cz>).
+	+ correct dependencies in Ada95/src/Makefile.in, so the builds with
+	  "--srcdir" work (report by Warren L Dodge).
+	+ correct missing definition of $(CC) in Ada95/gen/Makefile.in
+	  (reported by Warren L Dodge <warrend@mdhost.cse.tek.com>).
+	+ fix typos and whitespace in manpages (patch by Jason McIntyre
+	  <jmc@prioris.mini.pw.edu.pl>).
+
+20030503
+	+ fix form_driver() cases for REQ_CLR_EOF, REQ_CLR_EOL, REQ_DEL_CHAR,
+	  REQ_DEL_PREV and REQ_NEW_LINE, which did not ensure the cursor was at
+	  the editing position before making modifications.
+	+ add test/demo_forms and associated test/edit_field.c demos.
+	+ modify test/configure.in to use test/modules for the list of objects
+	  to compile rather than using the list of programs.
+
+20030419
+	+ modify logic of acsc to use the original character if no mapping is
+	  defined, noting that Solaris does this.
+	+ modify ncurses 'b' test to avoid using the acs_map[] array since
+	  20021231 changes it to no longer contain information from the acsc
+	  string.
+	+ modify makefile rules in c++, progs, tack and test to ensure that
+	  the compiler flags (e.g., $CFLAGS or $CCFLAGS) are used in the link
+	  command (report by Jose Luis Rico Botella <informatica@serpis.com>).
+	+ modify soft-key initialization to use A_REVERSE if A_STANDOUT would
+	  not be shown when colors are used, i.e., if ncv#1 is set in the
+	  terminfo as is done in "screen".
+
+20030412
+	+ add a test for slk_color(), in ncurses.c
+	+ fix some issues reported by valgrind in the slk_set() and slk_wset()
+	  code, from recent rewrite.
+	+ modify ncurses 'E' test to use show previous label via slk_label(),
+	  as in 'e' test.
+	+ modify wide-character versions of NewChar(), NewChar2() macros to
+	  ensure that the whole struct is initialized.
+
+20030405
+	+ modify setupterm() to check if the terminfo and terminal-modes have
+	  already been read.  This ensures that it does not reinvoke
+	  def_prog_mode() when an application calls more than one function,
+	  such as tgetent() and initscr() (report by Olaf Buddenhagen).
+
+20030329
+	+ add 'E' test to ncurses.c, to exercise slk_wset().
+	+ correct handling of carriage-return in wgetn_wstr(), used in demo of
+	  slk_wset().
+	+ first draft of slk_wset() function.
+
+20030322
+	+ improved warnings in tic when suppressing items to fit in termcap's
+	  1023-byte limit.
+	+ built a list in test/README showing which externals are being used
+	  by either programs in the test-directory or via internal library
+	  calls.
+	+ adjust include-options in CF_ETIP_DEFINES to avoid missing
+	  ncurses_dll.h, fixing special definitions that may be needed for
+	  etip.h (reported by Greg Schafer <gschafer@zip.com.au>).
+
+20030315
+	+ minor fixes for cardfile.c, to make it write the updated fields to
+	  a file when ^W is given.
+	+ add/use _nc_trace_bufcat() to eliminate some fixed buffer limits in
+	  trace code.
+
+20030308
+	+ correct a case in _nc_remove_string(), used by define_key(), to avoid
+	  infinite loop if the given string happens to be a substring of other
+	  strings which are assigned to keys (report by John McCutchan).
+	+ add key_defined() function, to tell which keycode a string is bound
+	  to (discussion with John McCutchan <ttb@tentacle.dhs.org>).
+	+ correct keybound(), which reported definitions in the wrong table,
+	  i.e., the list of definitions which are disabled by keyok().
+	+ modify demo_keydef.c to show the details it changes, and to check
+	  for errors.
+
+20030301
+	+ restructured test/configure script, make it work for libncursesw.
+	+ add description of link_fieldtype() to manpage (report by
+	  L Dee Holtsclaw <dee@sunbeltsoft.com>).
+
+20030222
+	+ corrected ifdef's relating to configure check for wchar_t, etc.
+	+ if the output is a socket or other non-tty device, use 1 millisecond
+	  for the cost in mvcur; previously it was 9 milliseconds because the
+	  baudrate was not known.
+	+ in _nc_get_tty_mode(), initialize the TTY buffer on error, since
+	  glibc copies uninitialized data in that case, as noted by valgrind.
+	+ modify tput to use the same parameter analysis as tparm() does, to
+	  provide for user-defined strings, e.g., for xterm title, a
+	  corresponding capability might be
+		title=\E]2;%p1%s^G,
+	+ modify MKlib_gen.sh to avoid passing "#" tokens through the C
+	  preprocessor.  This works around Mac OS X's preprocessor, which
+	  insists on adding a blank on each side of the token (report/analysis
+	  by Kevin Murphy <murphy@genome.chop.edu>).
+
+20030215
+	+ add configure check for wchar_t and wint_t types, rather than rely
+	  on preprocessor definitions.  Also work around for gcc fixinclude
+	  bug which creates a shadow copy of curses.h if it sees these symbols
+	  apparently typedef'd.
+	+ if database is disabled, do not generate run_tic.sh
+	+ minor fixes for memory-leak checking when termcap is read.
+
+20030208
+	+ add checking in tic for incomplete line-drawing character mapping.
+	+ updated configure script to reflect fix for AC_PROG_GCC_TRADITIONAL,
+	  which is broken in autoconf 2.5x for Mac OS X 10.2.3 (report by
+	  Gerben Wierda <Sherlock@rna.nl>).
+	+ make return value from _nc_printf_string() consistent.  Before,
+	  depending on whether --enable-safe-sprintf was used, it might not be
+	  cached for reallocating.
+
+20030201
+	+ minor fixes for memory-leak checking in lib_tparm.c, hardscroll.c
+	+ correct a potentially-uninitialized value if _read_termtype() does
+	  not read as much data as expected (report by Wolfgang Rohdewald
+	  <wr6@uni.de>).
+	+ correct several places where the aclocal.m4 macros relied on cache
+	  variable names which were incompatible (as usual) between autoconf
+	  2.13 and 2.5x, causing the test for broken-linker to give incorrect
+	  results (reports by Gerben Wierda <Sherlock@rna.nl> and Thomas Esser
+	  <te@dbs.uni-hannover.de>).
+	+ do not try to open gpm mouse driver if standard output is not a tty;
+	  the gpm library does not make this check (bug report for dialog
+	  by David Oliveira <davidoliveira@develop.prozone.ws>).
+
+20030125
+	+ modified emx.src to correspond more closely to terminfo.src, added
+	  emx-base to the latter -TD
+	+ add configure option for FreeBSD sysmouse, --with-sysmouse, and
+	  implement support for that in lib_mouse.c, lib_getch.c
+
+20030118
+	+ revert 20030105 change to can_clear_with(), does not work for the
+	  case where the update is made on cells which are blanks with
+	  attributes, e.g., reverse.
+	+ improve ifdef's to guard against redefinition of wchar_t and wint_t
+	  in curses.h (report by Urs Jansen).
+
+20030111
+	+ improve mvcur() by checking if it is safe to move when video
+	  attributes are set (msgr), and if not, reset/restore attributes
+	  within that function rather than doing it separately in the GoTo()
+	  function in tty_update.c (suggested by Philippe Blain).
+	+ add a message in run_tic.in to explain more clearly what does not
+	  work when attempting to create a symbolic link for /usr/lib/terminfo
+	  on OS/2 and other platforms with no symbolic links (report by John
+	  Polterak).
+	+ change several sed scripts to avoid using "\+" since it is not a BRE
+	  (basic regular expression).  One instance caused terminfo.5 to be
+	  misformatted on FreeBSD (report by Kazuo Horikawa
+	  <horikawa@FreeBSD.org> (see FreeBSD docs/46709)).
+	+ correct misspelled 'wint_t' in curs_get_wch.3x (Michael Elkins).
+
+20030105
+	+ improve description of terminfo operators, especially static/dynamic
+	  variables (comments by Mark I Manning IV <mark4th@earthlink.net>).
+	+ demonstrate use of FIELDTYPE by modifying test/ncurses 'r' test to
+	  use the predefined TYPE_ALPHA field-type, and by defining a
+	  specialized type for the middle initial/name.
+	+ fix MKterminfo.sh, another workaround for POSIXLY_CORRECT misfeature
+	  of sed 4.0
+	> patch by Philippe Blain:
+	+ optimize can_clear_with() a little by testing first if the parameter
+	  is indeed a "blank".
+	+ simplify ClrBottom() a little by allowing it to use clr_eos to clear
+	  sections as small as one line.
+	+ improve ClrToEOL() by checking if clr_eos is available before trying
+	  to use it.
+	+ use tputs() rather than putp() in a few cases in tty_update.c since
+	  the corresponding delays are proportional to the number of lines
+	  affected: repeat_char, clr_eos, change_scroll_region.
+
+20021231
+	+ rewrite of lib_acs.c conflicts with copying of SCREEN acs_map to/from
+	  global acs_map[] array; removed the lines that did the copying.
+
+20021228
+	+ change some overlooked tputs() calls in scrolling code to use putp()
+	  (report by Philippe Blain).
+	+ modify lib_getch.c to avoid recursion via wgetnstr() when the input
+	  is not a tty and consequently mode-changes do not work (report by
+	  <R.Chamberlin@querix.com>).
+	+ rewrote lib_acs.c to allow PutAttrChar() to decide how to render
+	  alternate-characters, i.e., to work with Linux console and UTF-8
+	  locale.
+	+ correct line/column reference in adjust_window(), needed to make
+	  special windows such as curscr track properly when resizing (report
+	  by Lucas Gonze <lgonze@panix.com>).
+	> patch by Philippe Blain:
+	+ correct the value used for blank in ClrBottom() (broken in 20000708).
+	+ correct an off-by-one in GoTo() parameter in _nc_scrolln().
+
+20021221
+	+ change several tputs() calls in scrolling code to use putp(), to
+	  enable padding which may be needed for some terminals (patch by
+	  Philippe Blain).
+	+ use '%' as sed substitute delimiter in run_tic script to avoid
+	  problems with pathname delimiters such as ':' and '@' (report by John
+	  Polterak).
+	+ implement a workaround so that line-drawing works with screen's
+	  crippled UTF-8 support (tested with 3.9.13).  This only works with
+	  the wide-character support (--enable-widec); the normal library will
+	  simply suppress line-drawing when running in a UTF-8 locale in screen.
+
+20021214
+	+ allow BUILD_CC and related configure script variables to be
+	  overridden from the environment.
+	+ make build-tools variables in ncurses/Makefile.in consistent with
+	  the configure script variables (report by Maciej W Rozycki).
+	+ modify ncurses/modules to allow
+		configure --disable-leaks --disable-ext-funcs
+	  to build (report by Gary Samuelson).
+	+ fix a few places in configure.in which lacked quotes (report by
+	  Gary Samuelson <gary.samuelson@verizon.com>).
+	+ correct handling of multibyte characters in waddch_literal() which
+	  force wrapping because they are started too late on the line (report
+	  by Sam Varshavchik).
+	+ small fix for CF_GNAT_VERSION to ignore the help-message which
+	  gnatmake adds to its version-message.
+	> Maciej W Rozycki <macro@ds2.pg.gda.pl>:
+	+ use AC_CHECK_TOOL to get proper values for AR and LD for cross
+	  compiling.
+	+ use $cross_compiling variable in configure script rather than
+	  comparing $host_alias and $target alias, since "host" is
+	  traditionally misused in autoconf to refer to the target platform.
+	+ change configure --help message to use "build" rather than "host"
+	  when referring to the --with-build-XXX options.
+
+20021206
+	+ modify CF_GNAT_VERSION to print gnatmake's version, and to allow for
+	  possible gnat versions such as 3.2 (report by Chris Lingard
+	  <chris@stockwith.co.uk>).
+	+ modify #define's for CKILL and other default control characters in
+	  tset to use the system's default values if they are defined.
+	+ correct interchanged defaults for kill and interrupt characters
+	  in tset, which caused it to report unnecessarily (Debian #171583).
+	+ repair check for missing C++ compiler, which is broken in autoconf
+	  2.5x by hardcoding it to g++ (report by Martin Mokrejs).
+	+ update config.guess, config.sub (2002-11-30)
+	+ modify configure script to skip --with-shared, etc., when the
+	  --with-libtool option is given, since they would be ignored anyway.
+	+ fix to allow "configure --with-libtool --with-termlib" to build.
+	+ modify configure script to show version number of libtool, to help
+	  with bug reports.  libtool still gets confused if the installed
+	  ncurses libraries are old, since it ignores the -L options at some
+	  point (tested with libtool 1.3.3 and 1.4.3).
+	+ reorder configure script's updating of $CPPFLAGS and $CFLAGS to
+	  prevent -I options in the user's environment from introducing
+	  conflicts with the build -I options (may be related to reports by
+	  Patrick Ash and George Goffe).
+	+ rename test/define_key.c to test/demo_defkey.c, test/keyok.c to
+	  test/demo_keyok.c to allow building these with libtool.
+
+20021123
+	+ add example program test/define_key.c for define_key().
+	+ add example program test/keyok.c for keyok().
+	+ add example program test/ins_wide.c for wins_wch() and wins_wstr().
+	+ modify wins_wch() and wins_wstr() to interpret tabs by using the
+	  winsch() internal function.
+	+ modify setcchar() to allow for wchar_t input strings that have
+	  more than one spacing character.
+
+20021116
+	+ fix a boundary check in lib_insch.c (patch by Philippe Blain).
+	+ change type for *printw functions from NCURSES_CONST to const
+	  (prompted by comment by Pedro Palhoto Matos <plpm@mega.ist.utl.pt>,
+	  but really from a note on X/Open's website stating that either is
+	  acceptable, and the latter will be used in a future revision).
+	+ add xterm-1002, xterm-1003 terminfo entries to demonstrate changes in
+	  lib_mouse.c (20021026) -TD
+	+ add screen-bce, screen-s entries from screen 3.9.13 (report by
+	  Adam Lazur <zal@debian.org>) -TD
+	+ add mterm terminfo entries -TD
+
+20021109
+	+ split-out useful fragments in terminfo for vt100 and vt220 numeric
+	  keypad, i.e., vt100+keypad, vt100+pfkeys, vt100+fnkeys and
+	  vt220+keypad.  The last as embedded in various entries had ka3 and
+	  kb2 interchanged (report/discussion with Leonard den Ottolander
+	  <leonardjo@hetnet.nl>).
+	+ add check in tic for keypads consistent with vt100 layout.
+	+ improve checks in tic for color capabilities
+
+20021102
+	+ check for missing/empty/illegal terminfo name in _nc_read_entry()
+	  (report by Martin Mokrejs, where $TERM was set to an empty string).
+	+ rewrote lib_insch.c, combining it with lib_insstr.c so both handle
+	  tab and other control characters consistently (report by Philippe
+	  Blain).
+	+ remove an #undef for KEY_EVENT from curses.tail used in the
+	  experimental NCURSES_WGETCH_EVENTS feature.  The #undef confuses
+	  dpkg's build script (Debian #165897).
+	+ fix MKlib_gen.sh, working around the ironically named POSIXLY_CORRECT
+	  feature of GNU sed 4.0 (reported by Ervin Nemeth <airwin@inf.bme.hu>).
+
+20021026
+	+ implement logic in lib_mouse.c to handle position reports which are
+	  generated when XFree86 xterm is initialized with private modes 1002
+	  or 1003.  These are returned to the application as the
+	  REPORT_MOUSE_POSITION mask, which was not implemented.  Tested both
+	  with ncurses 'a' menu (prompted by discussion with Larry Riedel
+	  <Larry@Riedel.org>).
+	+ modify lib_mouse.c to look for "XM" terminfo string, which allows
+	  one to override the escape sequence used to enable/disable mouse
+	  mode.  In particular this works for XFree86 xterm private modes
+	  1002 and 1003.  If "XM" is missing (note that this is an extended
+	  name), lib_mouse uses the conventional private mode 1000.
+	+ correct NOT_LOCAL() macro in lib_mvcur.c to refer to screen_columns
+	  where it used screen_lines (report by Philippe Blain).
+	+ correct makefile rules for the case when both --with-libtool and
+	  --with-gpm are given (report by Mr E_T <troll@logi.net.au>).
+	+ add note to terminfo manpage regarding the differences between
+	  setaf/setab and setf/setb capabilities (report by Pavel Roskin).
+
+20021019
+	+ remove redundant initialization of TABSIZE in newterm(), since it is
+	  already done in setupterm() (report by Philippe Blain).
+	+ add test/inserts.c, to test winnstr() and winsch().
+	+ replace 'sort' in dist.mk with script that sets locale to POSIX.
+	+ update URLs in announce.html.in (patch by Frederic L W Meunier).
+	+ remove glibc add-on files, which are no longer needed (report by
+	  Frederic L W Meunier).
+
+20021012 5.3 release for upload to ftp.gnu.org
+	+ modify ifdef's in etip.h.in to allow the etip.h header to compile
+	  with gcc 3.2 (patch by Dimitar Zhekov <jimmy@is-vn.bg>).
+	+ add logic to setupterm() to make it like initscr() and newterm(),
+	  by checking for $NCURSES_TRACE environment variable and enabling
+	  the debug trace in that case.
+	+ modify setupterm() to ensure that it initializes the baudrate, for
+	  applications such as tput (report by Frank Henigman).
+	+ modify definition of bits used for command-line and library debug
+	  traces to avoid overlap, using new definition TRACE_SHIFT to relate
+	  the two.
+	+ document tput's interpretation of parameterized strings according to
+	  whether parameters are given, etc. (discussion with Robert De Bath).
+
+20021005 pre-release
+	+ correct winnwstr() to account for non-character cells generated when
+	  a double-width character is added (report by Michael Bienia
+	  <michael@vorlon.ping.de>).
+	+ modify _nc_viswbuf2n() to provide better results using wctomb().
+	+ correct logic in _nc_varargs() which broke tracing of parameters for
+	  formats such as "%.*s".
+	+ correct scale factor in linux-c and linux-c-nc terminfo entries
+	  (report Floyd Davidson).
+	+ change tic -A option to -t, add the same option to infocmp for
+	  consistency.
+	+ correct "%c" implementation in lib_tparm.c, which did not map a null
+	  character to a 128 (cf: 980620) (patch by Frank Henigman
+	  <fjhenigman@mud.cgl.uwaterloo.ca>).
+
+20020928 pre-release
+	+ modify MKkey_defs.sh to check for POSIX sort -k option, use that if
+	  it is found, to accommodate newer utility which dropped the
+	  compatibility support for +number options (reported by Andrey A
+	  Chernov).
+	+ modify linux terminfo entry to use color palette feature from
+	  linux-c-nc entry (comments by Tomasz Wasiak and Floyd Davidson).
+	+ restore original color definitions in endwin() if init_color() was
+	  used, and resume those colors on the next doupdate() or refresh()
+	  (report by Tomasz Wasiak <tjwasiak@komputom.com.pl>).
+	+ improve debug-traces by modifying MKlib_gen.sh to generate calls
+	  to returnBool() and returnAttr().
+	+ add/use _nc_visbufn() and _nc_viswbufn() to limit the debug trace
+	  of waddnstr() and similar functions to match the parameters as used.
+	+ add/use _nc_retrace_bool() and _nc_retrace_unsigned().
+	+ correct type used by _nc_retrace_chtype().
+	+ add debug traces to some functions in lib_mouse.c
+	+ modify lib_addch.c to handle non-spacing characters.
+	+ correct parameter of RemAttr() in lib_bkgd.c, which caused the c++
+	  demo's boxes to lose the A_ALTCHARSET flag (broken in 20020629).
+	+ correct width computed in _tracedump(), which did not account for
+	  the attributes (broken in 20010602).
+	+ modify test/tracemunch to replace addresses for windows other than
+	  curscr, newscr and stdscr with window0, window1, etc.
+
+20020921 pre-release
+	+ redid fix for edit_man.sed path.
+	+ workaround for Cygwin bug which makes subprocess writes to stdout
+	  result in core dump.
+	+ documented getbegx(), etc.
+	+ minor fixes to configure script to use '%' consistently as a sed
+	  delimiter rather than '@'.
+	> patch by Philippe Blain:
+	+ add check in lib_overlay.c to ensure that the windows to be merged
+	  actually overlap, and in copywin(), limit the area to be touched
+	  to the lines given for the destination window.
+
+20020914 pre-release
+	+ modified curses.h so that if the wide-character version is installed
+	  overwriting /usr/include/curses.h, and if it relied on libutf8.h,
+	  then applications that use that header for wide-character support
+	  must define HAVE_LIBUTF8_H.
+	+ modify putwin(), getwin() and dupwin() to allow them to operate on
+	  pads (request by Philippe Blain).
+	+ correct attribute-merging in wborder(), broken in 20020216 (report
+	  by Tomasz Wasiak <tjwasiak@grubasek.komputom.com.pl>).
+	> patch by Philippe Blain:
+	+ corrected pop-counts in tparam_internal() to '!' and '~' cases.
+	+ use sizeof(NCURSES_CH_T) in one place that used sizeof(chtype).
+	+ remove some unused variables from mvcur test-driver.
+
+20020907 pre-release
+	+ change configure script to allow install of widec-character
+	  (ncursesw) headers to overwrite normal (ncurses) headers, since the
+	  latter is a compatible subset of the former.
+	+ fix path of edit_man.sed in configure script, needed to regenerate
+	  html manpages on Debian.
+	+ fix mismatched enums in vsscanf.c, which caused warning on Solaris.
+	+ update README.emx to reflect current patch used for autoconf.
+	+ change web- and ftp-site to invisible-island.net
+	> patch by Philippe Blain:
+	+ change case for 'P' in tparam_internal() to indicate that it pops
+	  a variable from the stack.
+	+ correct sense of precision and width in parse_format(), to avoid
+	  confusion.
+	+ modify lib_tparm.c, absorb really_get_space() into get_space().
+	+ modify getwin() and dupwin() to copy the _notimeout, _idlok and
+	  _idcok window fields.
+	+ better fix for _nc_set_type(), using typeMalloc().
+
+20020901 pre-release
+	+ change minor version to 3, i.e., ncurses 5.3
+	+ update config.guess, config.sub
+	+ retest build with each configure option; minor ifdef fixes.
+	+ make keyname() return a null pointer rather than "UNKNOWN STRING" to
+	  match XSI.
+	+ modify handling of wide line-drawing character functions to use the
+	  normal line-drawing characters when not in UTF-8 locale.
+	+ add check/fix to comp_parse.c to suppress warning about missing acsc
+	  string.  This happens in configurations where raw termcap information
+	  is processed; tic already does this and other checks.
+	+ modify tic's check for ich/ich1 versus rmir/smir to only warn about
+	  ich1, to match xterm patch #70 notes.
+	+ moved information for ripped-off lines into SCREEN struct to allow
+	  use in resizeterm().
+	+ add experimental wgetch_events(), ifdef'd with NCURSES_WGETCH_EVENTS
+	  (adapted from patch by Ilya Zakharevich - see ncurses/README.IZ).
+	+ amend check in kgetch() from 20020824 to look only for function-keys,
+	  otherwise escape sequences are not resolved properly.
+	> patch by Philippe Blain:
+	+ removed redundant assignment to SP->_checkfd from newterm().
+	+ check return-value of setupterm() in restartterm().
+	+ use sizeof(NCURSES_CH_T) in a few places that used sizeof(chtype).
+	+ prevent dupwin() from duplicating a pad.
+	+ prevent putwin() from writing a pad.
+	+ use typeRealloc() or typeMalloc() in preference to direct calls on
+	  _nc_doalloc().
+
+20020824
+	+ add a check in kgetch() for cooked characters in the fifo to avoid
+	  calling fifo_push() when a KEY_RESIZE is available (report/analysis
+	  by Sam Varshavchik <mrsam@courier-mta.com>).
+	+ fix an overlooked case for Redhat #68199 (Philippe Blain).
+	+ ensure clearerr() is called before using ferror() e.g., in
+	  lib_screen.c (report by Philippe Blain).
+
+20020817
+	+ modify lib_screen.c and lib_newwin.c to maintain the SCREEN-specific
+	  pointers for curscr/stdscr/newscr when scr_save() and scr_restore()
+	  modify the global curscr/stdscr/newscr variables.  Fixes Redhat
+	  #68199.
+	+ add checks for null pointer in calls to tparm() and tgoto() based on
+	  FreeBSD bug report.  If ncurses were built with termcap support, and
+	  the first call to tgoto() were a zero-length string, the result would
+	  be a null pointer, which was not handled properly.
+	+ correct a typo in terminfo.head, which gave the octal code for colon
+	  rather than comma.
+	+ remove the "tic -u" option from 20020810, since it did not account
+	  for nested "tc=" clauses, and when that was addressed, was still
+	  unsatisfactory.
+
+20020810
+	+ add tic -A option to suppress capabilities which are commented out
+	  when translating to termcap.
+	+ add tic -u option to provide older behavior of "tc=" clauses.
+	+ modified tic to expand all but the final "tc=" clause in a termcap
+	  entry, to accommodate termcap libraries which do not handle multiple
+	  tc clauses.
+	+ correct typo in curs_inopts.3x regarding CS8/CS7 usage (report by
+	  Philippe Blain).
+	+ remove a couple of redundant uses of A_ATTRIBUTES in expressions
+	  using AttrOf(), which already incorporates that mask (report by
+	  Philippe Blain).
+	+ document TABSIZE variable.
+	+ add NCURSES_ASSUMED_COLORS environment variable, to allow users to
+	  override compiled-in default black-on-white assumption used in
+	  assume_default_colors().
+	+ correct an off-by-one comparison against max_colors in COLORFGBG
+	  logic.
+	+ correct a use of uninitialized memory found by valgrind (reported by
+	  Olaf Buddenhagen <olafBuddenhagen@web.de>).
+	+ modified wresize() to ensure that a failed realloc will not corrupt
+	  the window structure, and to make subwindows fit within the resized
+	  window (completes Debian #87678, Debian #101699)
+
+20020803
+	+ fix an off-by-one in lib_pad.c check for limits of pad (patch by
+	  Philippe Blain).
+	+ revise logic for BeOS in lib_twait.c altered in 20011013 to restore
+	  logic used by lib_getch.c's support for GPM or EMX mouse (report by
+	  Philippe Blain)
+	+ remove NCURSES_CONST from several prototypes in curses.wide, to make
+	  the --enable-const --enable-widec configure options to work together
+	  (report by George Goffe <grgoffe@yahoo.com>).
+
+20020727
+	+ finish no-leak checking in cardfile.c, using this for testing changes
+	  to resizeterm().
+	+ simplify _nc_freeall() using delscreen().
+
+20020720
+	+ check error-return from _nc_set_tty_mode() in _nc_initscr() and
+	  reset_prog_mode() (report/patch by Philippe Blain).
+	+ regenerate configure using patch for autoconf 2.52, to address
+	  problem with identifying C++ bool type.
+	+ correct/improve logic to produce an exit status for errors in tput,
+	  which did not exit with an error when told to put a string not in the
+	  current terminfo entry (report by David Gomez <david@pleyades.net>).
+	+ modify configure script AC_OUTPUT() call to work around defect in
+	  autoconf 2.52 which adds an ifdef'd include to the generated
+	  configure definitions.
+	+ remove fstat() check from scr_init(), which also fixes a missing
+	  include for <sys/stat.h> from 20020713 (reported by David Ellement,
+	  fix suggested by Philippe Blain).
+	+ update curs_scanw.3x manpage to note that XSI curses differs from
+	  SVr4 curses: return-values are incompatible.
+	+ correct several prototypes in manpages which used const
+	  inconsistently with the curses.h file, and removed spurious const's
+	  in a few places from curses.h, e.g., for wbkgd() (report by Glenn
+	  Maynard <glenn@zewt.org>).
+	+ change internal type used by tparm() to long, to work with LP64 model.
+	+ modify nc_alloc.h to allow building with g++, for testing.
+
+20020713
+	+ add resize-handling to cardfile.c test program.
+	+ altered resizeterm() to avoid having it fail when a child window
+	  cannot be resized because it would be larger than its parent.  (More
+	  work must be done on this, but it works well enough to integrate).
+	+ improve a limit-check in lib_refresh.c
+	+ remove check in lib_screen.c relating dumptime to file's modification
+	  times, since that would not necessarily work for remotely mounted
+	  filesystems.
+	+ modify lrtest to simplify debugging changes to resizeterm, e.g.,
+	  t/T commands to enable/disable tracing.
+	+ updated status of multibyte support in TO-DO.
+	+ update contact info in source-files (patch by Juergen Pfeifer).
+
+20020706
+	+ add Caps.hpux11, as an example.
+	+ modify version_filter(), used to implement -R option for tic and
+	  infocmp, to use computed array offsets based on the Caps.* file which
+	  is actually configured, rather than constants which correspond to
+	  the Caps file.
+	+ reorganized lib_raw.c to avoid updating SP and cur_term state if the
+	  functions fail (reported by Philippe Blain).
+	+ add -Wundef to gcc warnings, adjust a few ifdef's to accommodate gcc.
+
+20020629
+	+ correct parameters to setcchar() in ncurses.c (cf: 20020406).
+	+ set locale in most test programs (view.c and ncurses.c were the
+	  only ones).
+	+ add configure option --with-build-cppflags (report by Maksim A
+	  Nikulin <M.A.Nikulin@inp.nsk.su>).
+	+ correct a typo in wide-character logic for lib_bkgnd.c (Philippe
+	  Blain).
+	+ modify lib_wacs.c to not cancel the acsc, smacs, rmacs strings when
+	  in UTF-8 locale.  Wide-character functions use Unicode values, while
+	  narrow-character functions use the terminfo data.
+	+ fix a couple of places in Ada95/samples which did not compile with
+	  gnat 3.14
+	+ modify mkinstalldirs so the DOS-pathname case is locale-independent.
+	+ fix locale problem in MKlib_gen.sh by forcing related variables to
+	  POSIX (C), using same approach as autoconf (set variables only if
+	  they were set before).  Update MKterminfo.sh and MKtermsort.sh to
+	  match.
+
+20020622
+	+ add charset to generated html.
+	+ add mvterm entry, adapted from a FreeBSD bug-report by Daniel Rudy
+	  <dcrudy@pacbell.net> -TD
+	+ add rxvt-16color, ibm+16color entries -TD
+	+ modify check in --disable-overwrite option so that it is used by
+	  default unless the --prefix/$prefix value is not /usr, in attempt to
+	  work around packagers, e.g., for Sun's freeware, who do not read the
+	  INSTALL notes.
+
+20020615
+	+ modify wgetch() to allow returning ungetch'd KEY_RESIZE as a function
+	  key code in get_wch().
+	+ extended resize-handling in test/ncurses 'a' menu to the entire
+	  stack of windows created with 'w' commands.
+	+ improve $COLORFGBG feature by interpreting an out-of-range color
+	  value as an SGR 39 or 49, for foreground/background respectively.
+	+ correct a typo in configure --enable-colorfgbg option, and move it
+	  to the experimental section (cf: 20011208).
+
+20020601
+	+ add logic to dump_entry.c to remove function-key definitions that do
+	  not fit into the 1023-byte limit for generated termcaps.  This makes
+	  hds200 fit.
+	+ more improvements to tic's warnings, including logic to ignore
+	  differences between delay values in sgr strings.
+	+ move definition of KEY_RESIZE into MKkeydefs.sh script, to
+	  accommodate Caps.osf1r5 which introduced a conflicting definition.
+
+20020525
+	+ add simple resize-handling in test/ncurses.c 'a' menu.
+	+ fixes in keyname() and _tracechar() to handle negative values.
+	+ make tic's warnings about mismatches in sgr strings easier to follow.
+	+ correct tic checks for number of parameters in smgbp and smglp.
+	+ improve scoansi terminfo entry, and add scoansi-new entry -TD
+	+ add pcvt25-color terminfo entry -TD
+	+ add kf13-kf48 strings to cons25w terminfo entry (reported by Stephen
+	  Hurd <deuce@lordlegacy.org> in newsgroup lucky.freebsd.bugs) -TD
+	+ add entrypoint _nc_trace_ttymode(), use this to distinguish the
+	  Ottyb and Nttyb members of terminal (aka cur_term), for tracing.
+
+20020523
+	+ correct and simplify logic for lib_pad.c change in 20020518 (reported
+	  by Mike Castle).
+
+20020518
+	+ fix lib_pad.c for case of drawing a double-width character which
+	  falls off the left margin of the pad (patch by Kriang Lerdsuwanakij
+	  <lerdsuwa@users.sourceforge.net>)
+	+ modify configure script to work around broken gcc 3.1 "--version"
+	  option, which adds unnecessary trash to the requested information.
+	+ adjust ifdef's in case SIGWINCH is not defined, e.g., with DJGPP
+	  (reported by Ben Decker <deckerben@freenet.de>).
+
+20020511
+	+ implement vid_puts(), vid_attr(), term_attrs() based on the narrow-
+	  character versions as well.
+	+ implement erasewchar(), killwchar() based on erasechar() and
+	  killchar().
+	+ modify erasechar() and killchar() to return ERR if the value was
+	  VDISABLE.
+	+ correct a bug in wresize() in handling subwindows (based on patch by
+	  Roger Gammans <rgammans@computer-surgery.co.uk>, report by Scott Beck
+	  <scott@gossamer-threads.com>).
+	+ improve test/tclock.c by making the second-hand update more often
+	  if gettimeofday() is available.
+
+20020429
+	+ workaround for Solaris sed with MKlib_gen.sh (reported by Andy
+	  Tsouladze <andyt@mypoints.com>).
+
+20020427
+	+ correct return-value from getcchar(), making it consistent with
+	  Solaris and Tru64.
+	+ reorder loops that generate makefile rules for different models vs
+	  subsets so configure --with-termlib works again.  This was broken by
+	  logic added to avoid duplicate rules in changes to accommodate cygwin
+	  dll's (reported by George.R.Goffe@seagate.com).
+	+ update config.guess, config.sub
+
+20020421
+	+ modify ifdef's in write_entry.c to allow use of symbolic links on
+	  platforms with no hard links, e.g., BeOS.
+	+ modify a few includes to allow compile with BeOS, which has stdbool.h
+	  with a conflicting definition for 'bool' versus its OS.h definition.
+	+ amend MKlib_gen.sh to work with gawk, which defines 'func' as an
+	  alias for 'function'.
+
+20020420
+	+ correct form of prototype for ripoffline().
+	+ modify MKlib_gen.sh to test that all functions marked as implemented
+	  can be linked.
+
+20020413
+	+ add manpages: curs_get_wstr.3x, curs_in_wchstr.3x
+	+ implement wgetn_wstr().
+	+ implement win_wchnstr().
+	+ remove redefinition of unget_wch() in lib_gen.c (reported by
+	  Jungshik Shin <jshin@jtan.com>).
+
+20020406
+	+ modified several of the test programs to allow them to compile with
+	  vendor curses implementations, e.g., Solaris, AIX -TD
+
+20020323
+	+ modified test/configure to allow configuring against ncursesw.
+	+ change WACS_xxx definition to use address, to work like Tru64 curses.
+
+20020317
+	+ add 'e' and 'm' toggles to 'a', 'A' tests in ncurses.c to demonstrate
+	  effect of echo/noecho and meta modes.
+	+ add 'A' test to ncurses.c to demonstrate wget_wch() and related
+	  functions.
+	+ add manpage: curs_get_wch.3x
+	+ implement unget_wch().
+	+ implement wget_wch().
+
+20020310
+	+ regenerated html manpages.
+	+ add manpages: curs_in_wch.3x, curs_ins_wch.3x, curs_ins_wstr.3x
+	+ implement wins_wch().
+	+ implement win_wch().
+	+ implement wins_nwstr(), wins_wstr().
+
+20020309
+	+ add manpages: curs_addwstr.3x, curs_winwstr.3x
+	+ implement winnwstr(), winwstr().
+
+20020223
+	+ add manpages: curs_add_wchstr.3x, curs_bkgrnd.3x
+	+ document wunctrl, key_name.
+	+ implement key_name().
+	+ remove const's in lib_box.c incorrectly leftover after splitting off
+	  lib_box_set.c
+	+ update llib-lncurses, llib-ncursesw, fix configure script related to
+	  these.
+
+20020218
+	+ remove quotes on "SYNOPSIS" in man/curs_box_set.3x, which resulted
+	  in spurious symlinks on install.
+
+20020216
+	+ implement whline_set(), wvline_set(), add manpage curs_border_set.
+	+ add subtest 'b' to 'F' and 'f' in ncurses.c to demonstrate use of
+	  box() and box_set() functions.
+	+ add subtest 'u' to 'F' in ncurses.c, to demonstrate use of addstr()
+	  given UTF-8 string equivalents of WACS_xxx symbols.
+	+ minor fixes to several manpages based on groff -ww output.
+	+ add descriptions of external variables of termcap interface to
+	  the manpage (report by Bruce Evans <bde@zeta.org.au>).
+	> patches by Bernhard Rosenkraenzer:
+	+ correct configure option --with-bool, which was executed as
+	  --with-ospeed.
+	+ add quotes for parameters of --with-bool and --with-ospeed configure
+	  options.
+	> patch by Sven Verdoolaege (report by Gerhard Haering
+	  <haering_linux@gmx.de>):
+	+ correct typos in definitions of several wide-character macros:
+	  waddwstr, wgetbkgrnd, mvaddwstr, mvwadd_wchnstr, mvwadd_wchnstr,
+	  mvwaddwstr.
+	+ pass $(CPPFLAGS) to MKlib_gen.sh, thereby fixing a missing definition
+	  of _XOPEN_SOURCE_EXTENDED, e.g., on Solaris
+
+20020209
+	+ implement wide-acs characters for UTF-8 locales.  When in UTF-8
+	  locale, ignore narrow version of acs.  Add 'F' test to test/ncurses.c
+	  to demonstrate.
+	+ correct prototype in keybound manpage (noted from a Debian mailing
+	  list item).
+
+20020202
+	+ add several cases to the wscanw() example in testcurs.c, showing the
+	  format.
+	+ implement a simple vsscanf() fallback function which uses the %n
+	  conversion to help parse the input data (prompted by discussion with
+	  Albert Chin-A-Young).
+	+ modify mk-1st.awk and test/Makefile.in to add $(LDFLAGS) when making
+	  shared libraries, and to use $(CFLAGS) when linking test programs
+	  (patch by Albert Chin-A-Young).
+	+ add a call to _nc_keypad() in keypad() to accommodate applications
+	  such as nvi, which use curses for output but not for input (fixes
+	  Debian #131263, cf: 20011215).
+	+ add entrypoints to resizeterm.c which provide better control over the
+	  process:  is_term_resized() and resize_term().  The latter restores
+	  the original design of resizeterm() before KEY_RESIZE was added in
+	  970906.  Do this to accommodate 20010922 changes to view.c, but allow
+	  for programs with their own sigwinch handler, such as lynx (reported
+	  by Russell Ruby <russ@math.orst.edu>).
+
+20020127
+	+ fix a typo in change to mk-1st.awk, which broke the shared-library
+	  makefile rules (reported by Martin Mokrejs).
+
+20020126
+	+ update config.guess, config.sub
+	+ finish changes needed to build dll's on cygwin.
+	+ fix a typo in mvwchat() macro (reported by Cy <yam@homerow.net).
+
+20020119
+	+ add case in lib_baudrate.c for B921600 (patch by Andrey A Chernov).
+	+ correct missing sed-editing stage in manpage installs which is used
+	  to rename manpages, broken in 20010324 fix for Debian #89939 (Debian
+	  #78866).
+	+ remove -L$(libdir) from linker flags, probably not needed any more
+	  since HPUX is handled properly (reported by Niibe Yutaka
+	  <gniibe@m17n.org>).
+	+ add configure check for mbstate_t, needed for wide-character
+	  configuration.  On some platforms we must include <wchar.h> to
+	  define this (reported by Daniel Jacobowitz).
+	+ incorporate some of the changes needed to build dll's on cygwin.
+
+20020112a
+	+ workaround for awk did not work with mawk, adjusted shell script.
+
+20020112
+	+ add Caps.osf1r5, as an example.
+	+ modify behavior of can_clear_with() so that if an application is
+	  running in a non-bce terminals with default colors enabled, it
+	  returns true, allowing the user to select/paste text without picking
+	  up extraneous trailing blanks (adapted from patch by Daniel
+	  Jacobowitz <dmj+@andrew.cmu.edu>).
+	+ modify generated curses.h to ifdef-out prototypes for extensions if
+	  they are disabled, and to define curses_version() as a string in that
+	  case.  This is needed to make the programs such as tic build in that
+	  configuration.
+	+ modified generated headers.sh to remove a gzip'd version of the
+	  target file if it exists, in case non-gzip'd manpages are installed
+	  into a directory where gzip'd ones exist.  In that case, the latter
+	  would be found.
+	+ corrected a redundant initialization of signal handlers from 20010922
+	  changes.
+	+ clarified bug-reporting address in terminfo.src (report by John H
+	  DuBois III <spcecdt@armory.com>).
+	> several fixes from Robert Joop:
+	+ do not use "-v" option of awk in MKkey_defs.sh because it does not
+	  work with SunOS nawk.
+	+ modify definitions for libutf8 in curses.h to avoid redefinition
+	  warnings for mblen
+	+ quoted references to compiler in shell command in misc/Makefile, in
+	  case it uses multiple tokens.
+
+20011229
+	+ restore special case from 20010922 changes to omit SA_RESTART when
+	  setting up SIGWINCH handler, which is needed to allow wgetch() to be
+	  interrupted by that signal.
+	+ updated configure macro CF_WITH_PATHLIST, to omit some double quotes
+	  not needed with autoconf 2.52
+	+ revert configure script to autoconf 2.13 patched with
+		autoconf-2.13-19990117.patch.gz (or later)
+	  from
+		ftp://invisible-island.net/autoconf/
+	  because autoconf 2.52 macro AC_PROG_AWK does not work on HPUX 11.0
+	  (report by David Ellement <ellement@sdd.hp.com>).  This also fixes a
+	  different problem configuring with Mac OS X (reported by Marc Smith
+	  <marc.a.smith@home.com>).
+
+20011222
+	+ modify include/edit_cfg.h to eliminate BROKEN_LINKER symbol from
+	  term.h
+	+ move prototype for _nc_vsscanf() into curses.h.in to omit
+	  HAVE_VSSCANF symbol from curses.h, which was dependent upon the
+	  ncurses_cfg.h file which is not installed.
+	+ use ACS_LEN rather than SIZEOF(acs_map) in trace code of lib_acs.c,
+	  to work with broken linker configuration, e.g., cygwin (report by
+	  Robert Joop <rj@rainbow.in-berlin.de>).
+	+ make napms() call _nc_timed_wait() rather than poll() or select(),
+	  to work around broken implementations of these on cygwin.
+
+20011218
+	+ drop configure macro CF_WIDEC_SHIFT, since that was rendered obsolete
+	  by Sven Verdoolaege's rewrite of wide-character support.  This makes
+	  libncursesw incompatible again, but makes the header files almost the
+	  same as in the narrow-character configuration.
+	+ simplify definitions that combine wide/narrow versions of bkgd, etc.,
+	  to eliminate differences between the wide/narrow versions of curses.h
+	+ correct typo in configure macro CF_FUNC_VSSCANF
+	+ correct location of call to _nc_keypad() from 20011215 changes which
+	  prevented keypad() from being disabled (reported by Lars Hecking).
+
+20011215
+	+ rewrote ncurses 'a' test to exercise wgetch() and keypad() functions
+	  better, e.g., by adding a 'w' command to create new windows which
+	  may have different keypad() settings.
+	+ corrected logic of keypad() by adding internal screen state to track
+	  whether the terminal's keypad-mode has been set.  Use this in
+	  wgetch() to update the keypad-mode according to whether the
+	  associated window's keypad-mode has been set with keypad().  This
+	  corrects a related problem restoring terminal state after handling
+	  SIGTSTP (reported by Mike Castle).
+	+ regenerate configure using patch for autoconf 2.52
+		autoconf-2.52-patch.gz
+	  at
+		ftp://invisible-island.net/autoconf/
+	+ update config.guess, config.sub from
+		http://subversions.gnu.org/cgi-bin/viewcvs/config/config/
+	+ minor changes to quoting in configure script to allow it to work
+	  with autoconf 2.52
+
+20011208
+	+ modify final checks in lib_setup.c for line and col values, making
+	  them independent.
+	+ modify acs_map[] if configure --broken-linker is specified, to make
+	  it use a function rather than an array (prompted by an incorrect
+	  implementation in cygwin package).
+	+ correct spelling of configure option --enable-colorfgbg, which
+	  happened to work if --with-develop was set (noted in cygwin package
+	  for ncurses).
+	+ modify ifdef for genericerror() to compile with SUNWspro Sun WorkShop
+	  6 update 1 C++ 5.2 (patch by Sullivan N Beck <sbeck@cise.ufl.edu>).
+	+ add configure checks to see if ncurses' fallback vsscanf() will
+	  compile either of the special cases for FILE structs, and if not,
+	  force it to the case which simply returns an error (report by
+	  Sullivan N Beck <sbeck@cise.ufl.edu> indicates that Solaris 8 with
+	  64-bits does not allow access to FILE's fields).
+	+ modify ifdef's for c++/cursesw.cc to use the fallback vsscanf() in
+	  the ncurses library if no better substitute for this can be found
+	  in the C++ runtime.
+	+ modify the build to name dynamic libraries according to the
+	  convention used on OS X and Darwin.  Rather than something like
+	  libncurses.dylib.5.2, Darwin would name it libncurses.  5.dylib.
+	  There are a few additional minor fixes, such as setting the library
+	  version and compatibility version numbers (patch by Jason Evans
+	  <jevans@apple.com>).
+	+ use 'sh' to run mkinstalldirs, to work around problems with buggy
+	  versions of 'make' on OS/2 (report by John Polterak <jp@eyup.org>).
+	+ correct typo in manpage description of curs_set() (Debian #121548).
+	+ replace the configure script existence-check for mkstemp() by one
+	  that checks if the function works, needed for older glibc and
+	  AmigaOS.
+
+20011201
+	+ modify script that generates fallbacks.c to compile a temporary
+	  copy of the terminfo source in case the host does not contain all of
+	  the entries requested for fallbacks (request by Greg Roelofs).
+	+ modify configure script to accommodate systems such as Mac OS X whose
+	  <stdbool.h> header defines a 'bool' type inconsistent with ncurses,
+	  which normally makes 'bool' consistent with C++.  Include <stdbool.h>
+	  from curses.h to force consistent usage, define a new type
+	  NCURSES_BOOL and related that to the exported 'bool' as either a
+	  typedef or definition, according to whether <stdbool.h> is present
+	  (based on a bug report for tin 1.5.9 by Aaron Adams <adamsa@mac.com>).
+
+20011124
+	+ added/updated terminfo entries for M$ telnet and KDE konsole -TD
+
+20011117
+	+ updated/expanded Apple_Terminal and Darwin PowerPC terminfo entries
+	  (Benjamin C W Sittler).
+	+ add putty terminfo entry -TD
+	+ if configuring for wide-curses, define _XOPEN_SOURCE_EXTENDED, since
+	  this may not otherwise be defined to make test/view.c compile.
+
+20011110
+	+ review/correct several missing/generated items in curses.wide, sorted
+	  the lists to make subsequent diff's easier to track.
+
+20011103
+	+ add manual pages for add_wch(), echo_wchar(), getcchar(),
+	  mvadd_wch(), mvwadd_wch(), setcchar(), wadd_wch() and wecho_wchar().
+	+ implement wecho_wchar()
+	+ modify _tracedump() to handle wide-characters by mapping them to '?'
+	  and control-characters to '.', to make the trace file readable.  Also
+	  dynamically allocate the buffer used by _tracedump() for formatting
+	  the results.
+	+ modify T_CALLED/T_RETURN macros to ease balancing call/return lines
+	  in a trace by using curly braces.
+	+ implement _nc_viscbuf(), for tracing cchar_t arrays.
+	+ correct trace-calls in setcchar() and getcchar() functions, which
+	  traced the return values but not the entry to each function.
+	+ correct usage message in test/view.c, which still mentioned -u flag.
+
+20011027
+	+ modify configure script to allow building with termcap only, or with
+	  fallbacks only.  In this case, we do not build tic and toe.
+	+ add configure --with-termpath option, to override default TERMPATH
+	  value of /etc/termcap:/usr/share/misc/termcap.
+	+ cosmetic change to tack: make menu descriptions agree with menu
+	  titles.
+
+20011020
+	+ rewrote limit-checks in wscrl() and associated _nc_scroll_window(),
+	  to ensure that if the parameter of wscrl() is larger than the size of
+	  the scrolling region, then the scrolling region will be cleared
+	  (report by Ben Kohlen <bckohlen@yahoo.com>).
+	+ add trace/varargs.c, using this to trace parameters in lib_printw.c
+	+ implement _tracecchar_t2() and _tracecchar_t().
+	+ split-out trace/visbuf.c
+	+ correct typo in lib_printw.c changes from 20010922 (report by Mike
+	  Castle).
+
+20011013
+	+ modify run_tic.sh to check if the build is a cross-compile.  In that
+	  case, do not use the build's tic to install the terminfo database
+	  (report by Rafael Rodriguez Velilla <rrv@tid.es>).
+	+ modify mouse click resolution so that mouseinterval(-1) will disable
+	  it, e.g., to handle touchscreens via a slow connection (request by
+	  Byron Stanoszek <gandalf@winds.org>).
+	+ correct mouseinterval() default value shown in curs_mouse.3x
+	+ remove conflicting definition of mouse_trafo() (reported by Lars
+	  Hecking, using gcc 2.95.3).
+
+20011001
+	+ simpler fix for signal_name(), to replace the one overlooked in
+	  20010929 (reported by Larry Virden).
+
+20010929
+	+ add -i option to view.c, to test ncurses' check for non-default
+	  signal handler for SIGINT, etc.
+	+ add cases for shared-libraries on Darwin/OS X (patch by Rob Braun
+	  <bbraun@synack.net>).
+	+ modify tset to restore original I/O modes if an error is encountered.
+	  Also modify to use buffered stderr consistently rather than mixing
+	  with write().
+	+ change signal_name() function to use if-then-else rather than case
+	  statement, since signal-values aren't really integers (reported by
+	  Larry Virden).
+	+ add limit checks in wredrawln(), fixing a problem where lynx was
+	  repainting a pad which was much larger than the screen.
+
+20010922
+	+ fix:  PutRange() was counting the second part of a wide character as
+	  part of a run, resulting in a cursor position that was one too far
+	  (patch by Sven Verdoolaege).
+	+ modify resizeterm() to not queue a KEY_RESIZE if there was no
+	  SIGWINCH, thereby separating the two styles of SIGWINCH handling
+	  in test/view.c
+	+ simplified lib_tstp.c, modify it to use SA_RESTART flag for SIGWINCH.
+	+ eliminate several static buffers in the terminfo compiler, using
+	  allocated buffers.
+	+ modify MKkeyname.awk so that keyname() does not store its result into
+	  a static buffer that is overwritten by the next call.
+	+ reorganize the output of infocmp -E and -e options to compile cleanly
+	  with gcc -Wwrite-strings warnings.
+	+ remove redefinition of chgat/wchgat/mvwchgat from curses.wide
+
+20010915
+	+ add label to test/view.c, showing the name of the last key or signal
+	  that made the screen repaint, to make it clearer when a sigwinch
+	  does this.
+	+ use ExitProgram() consistently in the test-programs to make it
+	  simpler to test leaks with dmalloc, etc.
+	+ move hashtab static data out of hashmap.c into SCREEN struct.
+	+ make NO_LEAK code compile with revised WINDOWLIST structs.
+
+20010908
+	+ modify tgetent() to check if exit_attribute_mode resets the alternate
+	  character set, and if so, attempt to adjust the copy of the termcap
+	  "me" string which it will return to eliminate that part.  In
+	  particular, 'screen' would lose track of line-drawing characters
+	  (report by Frederic L W Meunier <0@pervalidus.net>, analysis by
+	  Michael Schroeder).
+
+20010901
+	+ specify DOCTYPE in html manpages.
+	+ add missing macros for several "generated" functions:  attr_get(),
+	  attr_off(), attr_on(), attr_set(), chgat(), mvchgat(), mvwchgat() and
+	  mouse_trafo().
+	+ modify view.c to agree with non-experimental status of ncurses'
+	  sigwinch handler:
+	  + change the sense of the -r option, making it default to ncurses'
+	    sigwinch handler.
+	  + add a note explaining what functions are unsafe in a signal
+	    handler.
+	  + add a -c option, to set color display, for testing.
+	+ unset $data variable in MKterminfo.sh script, to address potential
+	  infinite loop if shell malfunction (report by Samuel Mikes
+	  <smikes@cubane.com>, for bash 2.05.0 on a Linux 2.0.36 system).
+	+ change kbs in mach terminfo entries to ^?  (Marcus Brinkmann
+	  <Marcus.Brinkmann@ruhr-uni-bochum.de>).
+	+ correct logic for COLORFGBG environment variable: if rxvt is compiled
+	  with xpm support, the variable has three fields, making it slightly
+	  incompatible with itself.  In either case, the background color is
+	  the last field.
+
+20010825
+	+ move calls to def_shell_mode() and def_prog_mode() before loop with
+	  callbacks in lib_set_term.c, since the c++ demo otherwise initialized
+	  the tty modes before saving them (patch by John David Anglin
+	  <dave@hiauly1.hia.nrc.ca>).
+	+ duplicate logic used to initialize trace in newterm(), in initscr()
+	  to avoid confusing trace of initscr().
+	+ simplify allocation of WINDOW and WINDOWLIST structs by making the
+	  first a part of the second rather than storing a pointer.  This saves
+	  a call to malloc for each window (discussion with Philippe Blain).
+	+ remove unused variable 'used_ncv' from lib_vidattr.c (Philippe
+	  Blain).
+	+ modify c++/Makefile.in to accommodate archive programs that are
+	  different for C++ than for C, and add cases for vendor's C++
+	  compilers on Solaris and IRIX (report by Albert Chin-A-Young).
+	+ correct manpage description of criteria for deciding if the terminal
+	  supports xterm mouse controls.
+	+ add several configure script options to aid with cross-compiling:
+	  --with-build-cc, --with-build-cflags, --with-build-ldflags, and
+	  --with-build-libs (request by Greg Roelofs).
+	+ change criteria for deciding if configure is cross-compiling from
+	  host/build mismatch to host/target mismatch (request by Greg Roelofs
+	  <greg.roelofs@philips.com>).
+	+ correct logic for infocmp -e and -E options which writes the data for
+	  the ext_Names[] array.  This is needed if one constructs a fallback
+	  table for a terminfo entry which uses extended termcap names, e.g.,
+	  AX in a color xterm.
+	+ fix undefined NCURSES_PATHSEP when configure --disable-database
+	  option is given.
+
+20010811
+	+ fix for VALID_BOOLEAN() macro when char is not signed.
+	+ modify 'clean' rule for C++ binding to work with Sun compiler, which
+	  caches additional information in a subdirectory of the objects.
+	+ added llib-ncursesw.
+
+20010804
+	+ add Caps.keys example for experimental extended function keys
+	  (adapted from a patch by Ilya Zakharevich).
+	+ correct parameter types of vidputs() and vidattr() to agree with
+	  header files (report by William P Setzer).
+	+ fix typos in several man-pages (patch by William P Setzer).
+	+ remove unneeded ifdef for __GNUG__ in CF_CPP_VSCAN_FUNC configure
+	  macro, which made ncurses C++ binding fail to build with other
+	  C++ compilers such as HPUX 11.x (report by Albert Chin-A-Young).
+	+ workaround for bug in HPUX 11.x C compiler: add a blank after
+	  NCURSES_EXPORT macro in form.h (report by Albert Chin-A-Young)
+	+ ignore blank lines in Caps* files in MKkey_defs.sh script (report by
+	  Albert Chin-A-Young).
+	+ correct definition of key_end in Caps.aix4, which left KEY_END
+	  undefined (report by Albert Chin-A-Young).
+	+ remove a QNX-specific fallback prototype for vsscanf(), which is
+	  obsolete with QNX RTP.
+	+ review/fix some of the T() and TR() macro calls, having noticed that
+	  there was no data for delwin() in a trace of dialog because there was
+	  no returnVoid call for wtimeout().  Also, traces in lib_twait.c are
+	  now selected under TRACE_IEVENT rather than TRACE_CALLS.
+
+20010728
+	+ add a _nc_access() check before opening files listed via $TERMPATH.
+	+ using modified man2html, regenerate some of the html manpages to fix
+	  broken HREF's where the link was hyphenated.
+
+20010721
+	+ add some limit/pointer checks to -S option of tputs.
+	+ updated/expanded Apple_Terminal and Darwin PowerPC terminfo entries
+	  (Benjamin C W Sittler).
+	+ add a note in curs_termcap.3x regarding a defect in the XSI
+	  description of tgetent (based on a discussion with Urs Jansen
+	  regarding the HPUX 11.x implementation, whose termcap interface is
+	  not compatible with existing termcap programs).
+	+ modify manhtml rule in dist.mk to preserve copyright notice on the
+	  generated files, as well as to address HTML style issues reported by
+	  tidy and weblint.  Regenerated/updated corresponding html files.
+	+ comment out use of Protected_Character and related rarely used
+	  attributes in ncurses Ada95 test/demo to compile with wide-character
+	  configuration.
+
+20010714
+	+ implement a simple example in C++ demo to test scanw().
+	+ corrected stdio function used to implement scanw() in cursesw.cc
+	+ correct definition of RemAttr() macro from 20010602 changes, which
+	  caused C++ SillyDemo to not show line-drawing characters.
+	+ modify C++ binding, adding getKey() which can be overridden by user
+	  to substitute functions other than getch() for keyboard processing
+	  of forms and menus (patch by Juergen Pfeifer).
+
+20010707
+	+ fix some of the trace calls which needed modification to work with
+	  new wide-character structures.
+	+ modify magic-cookie code in tty_update.c to compile with new
+	  wide-character structures (report by <George.R.Goffe@seagate.com>).
+	+ ensure that _XOPEN_SOURCE_EXTENDED is defined in curses.priv.h if
+	  compiling for wide-character configuration.
+	+ make addwnstr() handle non-spacing characters (patch by Sven
+	  Verdoolaege).
+
+20010630
+	+ add configure check to define _GNU_SOURCE, needed to prop up glibc
+	  header files.
+	+ split-out include/curses.wide to solve spurious redefinitions caused
+	  by defining _GNU_SOURCE, and move includes for <signal.h> before
+	  <curses.h> to work around misdefinition of ERR in glibc 2.1.3 header
+	  file.
+	+ extended ospeed change to NetBSD and OpenBSD -TD
+	+ modify logic in lib_baudrate.c for ospeed, for FreeBSD to make it
+	  work properly for termcap applications (patch by Andrey A Chernov).
+
+20010623
+	+ correct an overlooked CharOf/UChar instance (reports by Eugene Lee
+	  <eugene@anime.net>, Sven Verdoolaege).
+	+ correct unneeded ifdef for wunctrl() (reported by Sven Verdoolaege)
+
+20010618
+	+ change overlooked several CharOf/UChar instances.
+	> several patches from Sven Verdoolaege:
+	+ correct a typo in wunctrl(), which made it appear that botwc() was
+	  needed (no such function: use btowc()).
+	+ reimplement wide-character demo in test/view.c, using new functions.
+	+ implement getcchar(), setcchar(), wadd_wchnstr() and related macros.
+	+ fix a syntax problem with do/if/while in PUTC macro (curses.priv.h).
+
+20010616
+	+ add parentheses in macros for malloc in test.priv.h, fixes an
+	  expression in view.c (report by Wolfgang Gutjahr <gutw@knapp.co.at>).
+	+ add Caps.uwin, as an example.
+	+ change the way curses.h is generated, making the list of function
+	  key definitions extracted from the Caps file.
+	+ add #undef's before possible redefinition of ERR and OK in curses.h
+	+ modify logic in tic, toe, tput and tset which checks for basename of
+	  argv[0] to work properly on systems such as OS/2 which have
+	  case-independent filenames and/or program suffixes, e.g., ".ext".
+
+20010609
+	+ add a configure check, if --enable-widec is specified, for putwc(),
+	  which may be in libutf8.
+	+ remove some unnecessary text from curs_extend.3x and
+	  default_colors.3x which caused man-db to make incorrect symbolic
+	  links (Debian #99550).
+	+ add configure check if cast for _IO_va_list is needed to compile
+	  C++ vscan code (Debian #97945).
+	> several patches from Sven Verdoolaege:
+	+ correct code that used non-standard auto-initialization of a struct,
+	  which gcc allows (report by Larry Virden).
+	+ use putwc() in PUTC() macro.
+	+ make addstr() work for the special case where the codeset is
+	  non-stateful (eg. UTF-8), as well as stateful codesets.
+
+20010603
+	+ correct loop expression in NEXT_CHAR macro for lib_addstr.c changes
+	  from 20010602 (report by Mike Castle).
+
+20010602
+	+ modify mvcur() to avoid emitting newline characters when nonl() mode
+	  is set.  Normally this is not a problem since the actual terminal
+	  mode is set to suppress nl/crlf translations, however it is useful to
+	  allow the caller to manipulate the terminal mode to avoid staircasing
+	  effects after spawning a process which writes messages (for lynx
+	  2.8.4) -TD
+	> several patches from Sven Verdoolaege <skimo@kotnet.org>:
+	+ remove redundant type-conversion in fifo_push()
+	+ correct definition of addwstr() macro in curses.h.in
+	+ remove _nc_utf8_outch()
+	+ rename most existing uses of CharOf() to UChar(), e.g., where it is
+	  used to prevent sign-extension in ctype macros.
+	+ change some chtype's to attr_t's where the corresponding variables
+	  are used to manipulate attributes.
+	+ UpdateAttr() was applied to both attributes (attr_t) and characters
+	  (chtype).  Modify macro and calls to it to make these distinct.
+	+ add CharEq() macro, use in places where wide-character configuration
+	  implementation uses a struct for cchar_t.
+	+ moved struct ldat into curses.priv.h, to hide implementation details.
+	+ change CharOf() macro to use it for masking A_CHARTEXT data from
+	  chtype's.
+	+ add L() macro to curses.priv.h, for long-character literals.
+	+ replace several assignments from struct ldat entries to chtype or
+	  char values with combinations of CharOf() and AttrOf() macros.
+	+ add/use intermediate ChAttrOf() and ChCharOf() macros where we know
+	  we are using chtype data.
+	+ add/use lowlevel attribute manipulation macros AddAttr(), RemAttr()
+	  and SetAttr().
+	+ add/use SetChar() macro, to change a cchar_t based on a character and
+	  attributes.
+	+ convert most internal use of chtype to NCURSES_CH_T, to simplify use
+	  of cchar_t for wide-character configuration.  Similarly, use ARG_CH_T
+	  where a pointer would be more useful.
+	+ add stubs for tracing cchar_t values.
+	+ add/use macro ISBLANK()
+	+ add/use constructors for cchar_t's: NewChar(), NewChar2().
+	+ add/use macros CHREF(), CHDEREF(), AttrOfD(), CharOfD() to facilitate
+	  passing cchar_t's by address.
+	+ add/use PUTC_DATA, PUTC() macros.
+	+ for wide-character configuration, move the window background data to
+	  the end of the WINDOW struct so that whether _XOPEN_SOURCE_EXTENDED
+	  is defined or not, the offsets in the struct will not change.
+	+ modify addch() to work with wide-characters.
+	+ mark several wide-character functions as generated in curses.h.in
+	+ implement wunctrl(), wadd_wch(), wbkgrndset(), wbkgrnd(),
+	  wborder_set() and waddnwstr().
+
+20010526
+	+ add experimental --with-caps=XXX option to customize to similar
+	  terminfo database formats such as AIX 4.x
+	+ add Caps.aix4 as an example.
+	+ modify Caps to add columns for the the KEY_xxx symbols.
+	+ modify configure --with-widec to suppress overwrite of libcurses.so
+	  and curses.h
+	+ add checks to toe.c to avoid being confused by files and directories
+	  where we would expect the reverse, e.g., source-files in the
+	  top-level terminfo levels as is the case for AIX.
+
+20010519
+	+ add top-level 'depend' rule for the C sources, assuming that the
+	  makedepend program is available.  As a side-effect, this makes
+	  the generated sources, as in "make sources" (prompted by a report
+	  by Mike Castle that "make -j" fails because the resulting parallel
+	  processes race to generate ncurses/names.c).
+	+ modify configure script so that --disable-overwrite option's action
+	  to add a symbolic link for libcurses applies to the static library as
+	  well as the shared library when both are configured (report by Felix
+	  Natter <f.natter@ndh.net>).
+	+ add ELKS terminfo entries (Federico Bianchi
+	  <bianchi@www.arte.unipi.it>)
+	+ add u6 (CSR) to Eterm (Michael Jennings).
+
+20010512
+	+ modify test/ncurses.c to work with xterm-256color, which has fewer
+	  color pairs than colors*colors (report by David Ellement
+	  <ellement@sdd.hp.com>).
+
+20010505
+	+ corrected screen.xterm-xfree86 entry.
+	+ update comment in Caps regarding IBM (AIX) function-key definitions.
+
+20010421
+	+ modify c++/Makefile.in to link with libncurses++w.a when configured
+	  for wide-characters (patch by Sven Verdoolaege).
+	+ add check in _nc_trace_buf() to refrain from freeing a null pointer.
+	+ improve CF_PROG_INSTALL macro using CF_DIRNAME.
+	+ update config.guess, config.sub from autoconf 2.49e (alpha).
+
+20010414
+	+ add secondary check in tic.c, similar_sgr() to see if the reason
+	  for mismatch was that the individual capabilities used a time-delay
+	  while sgr did not.  Used this to cleanup mismatches, e.g., in vt100,
+	  and remove time-delay from Apple_Terminal entries.
+	+ add Apple_Terminal terminfo entries (Benjamin C W Sittler
+	  <bsittler@iname.com>).
+	+ correct definitions of shifted editing keys for xterm-xfree86 -TD
+	+ fix a bug in test/bs.c from 20010407 (patch by Erik Sigra).
+	+ prevent relative_move() from doing an overwrite if it detects 8-bit
+	  characters when configured for UTF-8 (reported by Sven Verdoolaege
+	  <skimo@kotnet.org>).
+
+20010407
+	+ add configure checks for strstream.h vscan function, and similar
+	  stdio-based function which may be used in C++ binding for gcc 3.0
+	  (reports by George Goffe, Lars Hecking, Mike Castle).
+	+ rewrite parts of configure.in which used changequote().  That feature
+	  is broken in the latest autoconf alphas (e.g., 2.49d).
+	+ add a missing pathname for ncurses_dll.h, needed when building in
+	  a directory outside the source tree (patch by Sven Verdoolaege
+	  <skimo@kotnet.org>).
+	> fix 2 bugs in test/bs.c Erik Sigra <sigra@home.se>:
+	+ no ships were ever placed in the last row or in the last column.
+	  This made the game very easy to win, because you never had to waste
+	  any shots there, but the computer did.
+	+ the squares around a sunken ship that belonged to the player were not
+	  displayed as already hit by the computer, like it does for the
+	  player.
+
+20010331
+	+ add some examples of customizing screen's terminfo:
+	  screen.xterm-xfree86, screen.xterm-r6, screen.teraterm -TD
+	+ modify screen's terminfo entry to match the khome/kend in screen
+	  3.09.08 (Debian #92215).
+	+ correct a memory leak in forms library (report by Stefan Vogtner
+	  <stefan@vogtner.de>) (patch by Juergen Pfeifer).
+
+20010324
+	+ change symbols used to guard against repeated includes to begin
+	  consistently with "NCURSES_" rather than a leading underscore.  There
+	  are other symbols defined in the header files which begin with a
+	  leading underscore, but they are part of the legacy interface.
+	+ reorder includes in c++ binding so that rcs identifiers can be
+	  compiled-in.
+	+ add .cc.ii rule to c++ makefile, to get preprocessor output for
+	  debugging.
+	+ correct configure script handling of @keyword@ substitutions when the
+	  --with-manpage-renames option is given (cf: 20000715, fixes Debian
+	  #89939).
+	+ report stack underflow/overflow in tparm() when tic -cv option is
+	  given.
+	+ remove spurious "%|" operator from xterm-xfree86 terminfo entry,
+	  (reported by Adam Costello <amc@cs.berkeley.edu>, Debian #89222).
+
+20010310
+	+ cleanup of newdemo.c, fixing some ambiguous expressions noted by gcc
+	  2.95.2, and correcting some conflicting color pair initializations.
+	+ add missing copyright notice for cursesw.h
+	+ review, make minor fixes for use of '::' for referring to C-language
+	  interface from C++ binding.
+	+ modify configure check for g++ library slightly to accommodate
+	  nonstandard version number, e.g., <vendor>-2.7 (report by Ronald Ho
+	  <rho@mipos2.intel.com>).
+	+ add configure check for c++ <sstream> header, replace hardcoded
+	  ifdef.
+	+ workaround for pre-release of gcc 3.0 libstdc++, which has dropped
+	  vscan from strstreambuf to follow standard, use wrapper for C vscanf
+	  instead (report by George Goffe <grgoffe@excite.com> and Matt Taggart
+	  <taggart@carmen.fc.hp.com>, fixes Debian .
+
+20010303
+	+ modify interface of _nc_get_token() to pass 'silent' parameter to it,
+	  to make quieter loading of /etc/termcap (patch by Todd C Miller).
+	+ correct a few typos in curs_slk.3x and curs_outopts.3x manpages
+	  (patch by Todd C Miller).
+
+20010224
+	+ compiler-warning fixes (reported by Nelson Beebe).
+
+20010210
+	+ modify screen terminfo entry to use new 3.9.8 feature allowing xterm
+	  mouse controls -TD
+
+20010203
+	+ broaden patterns used to match OS/2 EMX in configure script to cover
+	  variant used in newer config.guess/config.sub
+	+ remove changequote() calls from configure script, since this feature
+	  is broken in the autoconf 2.49c alpha, maintainers decline to fix.
+	+ remove macro callPutChar() from tty_update.c, since this is no longer
+	  needed (reported by Philippe Blain).
+	+ add a null-pointer check in tic.c to handle the case when the input
+	  file is really empty.  Modify the next_char() function in comp_scan.c
+	  to allow arbitrarily long lines, and incidentally supply a newline to
+	  files that do not end in a newline.  These changes improve tic's
+	  recovery from attempts to read binary files, e.g., its output from
+	  the terminfo database (reported by Bernhard Rosenkraenzer).
+
+20010127
+	+ revert change to c++/demo.cc from 20001209, which changed definition
+	  of main() apparently to accommodate cygwin linker, but broke the demo
+	  program.
+	+ workaround for broken egcs 2.91.66 which calls member functions
+	  (i.e., lines() and colors() of NCursesWindow before calling its
+	  constructor.  Add calls to initialize() in a few constructors which
+	  did not do this already.
+	+ use the GNAT preprocessor to make the necessary switch between TRACE
+	  and NO_TRACE configurations (patch by Juergen Pfeifer).
+	> patches by Bernhard Rosenkraenzer:
+	+ modify kterm terminfo entry to use SCS sequence to support alternate
+	  character set (it does not work with SI/SO).
+	+ --with-ospeed=something didn't work.  configure.in checked for a
+	  $enableval where it should check for $withval.  Also,
+	  ncurses/llib-lncurses still had a hardcoded short.
+
+20010114
+	+ correction to my merge of Tom Riddle's patch that broke tic in some
+	  conditions (reported by Enoch Wexler <enoch@wexler.co.il>) -TD
+
+20010113
+	+ modify view.c to test halfdelay().  Like other tests, this recognizes
+	  the 's' and space commands for stopping/starting polled input, shows
+	  a freerunning clock in the header.  If given a parameter to 's', that
+	  makes view.c use halfdelay() with that parameter rather than
+	  nodelay().
+	+ fix to allow compile with the experimental configure option
+	  --disable-hashmap.
+	+ modify postprocess_termcap() to avoid overwriting key_backspace,
+	  key_left, key_down when processing a non-base entry (report/patch by
+	  Tom Riddle).
+	+ modify _nc_wrap_entry(), adding option to reallocate the string
+	  table, needed in _nc_merge_entry() when merging termcap entries.
+	  (adapted from report/patch by Tom Riddle <ftr@oracom.com>).
+	+ modify a few configure script macros to keep $CFLAGS used only for
+	  compiler options, preprocessor options in $CPPFLAGS.
+
+20001230
+	+ correct marker positions in lrtest.c after receiving a sigwinch.
+	+ fix ifdef's in ncurses.c to build against pre-5.2 for testing.
+	+ fixes to tclock for resizing behavior, redundant computation (report
+	  and patch by A M Kuchling <akuchlin@mems-exchange.org>).
+
+20001216
+	+ improved scoansi terminfo entry -TD
+	+ modify configure script and makefile in Ada95/src to compile a stub
+	  for the trace functions when ncurses does not provide those.
+
+20001209
+	+ add ncurses_dll.h and related definitions to support generating DLL's
+	  with cygwin (adapted from a patch by Charles Wilson
+	  <cwilson@ece.gatech.edu>, changed NCURSES_EXPORT macro to make it
+	  work with 'indent') -TD
+
+20001202
+	+ correct prototypes for some functions in curs_termcap.3x, matching
+	  termcap.h, which matches X/Open.
+	> patch by Juergen Pfeifer:
+	+ a revised version of the Ada enhancements sent in by "H.
+	  Nanosecond", aka Eugene V Melaragno <aldomel@ix.netcom.com>.  This
+	  patch includes
+	  - small fixes to the existing ncurses binding
+	  - addition of some more low-level functions to the binding, including
+	    termcap and terminfo functions
+	  - An Ada implementation of the "ncurses" test application originally
+	    written in C.
+
+20001125
+	+ modify logic in lib_setup.c to allow either lines or columns value
+	  from terminfo to be used if the screen size cannot be determined
+	  dynamically rather than requiring both (patch by Ehud Karni
+	  <ehud@unix.simonwiesel.co.il>).
+	+ add check in lib_tgoto.c's is_termcap() function to reject null or
+	  empty strings (reported by Valentin Nechayev <netch@netch.kiev.ua> to
+	  freebsd-bugs).
+	+ add definition from configure script that denotes the path-separator,
+	  which is normally a colon.  The path-separator is a semicolon on
+	  OS/2 EMX and similar systems which may use a colon within pathnames.
+	+ alter logic to set default for --disable-overwrite option to set it
+	  to 'yes' if the --prefix/$prefix value is not /usr/local, thereby
+	  accommodating the most common cause of problems: gcc's nonstandard
+	  search rules.  Other locations such as /usr/local/ncurses will
+	  default to overwriting (report by Lars Hecking <lhecking@nmrc.ie>).
+
+20001118
+	+ modify default for --disable-overwrite configure option to disable
+	  if the --prefix or $prefix value is not /usr.
+	+ add cygwin to systems for which ncurses is installed by default into
+	  /usr rather than /usr/local.
+
+20001111
+	+ minor optimization in comp_error.c and lib_termname.c, using
+	  strncat() to replace strncpy() (patch by Solar Designer).
+	+ add a use_terminfo_vars() check for $HOME/.termcap, and check for
+	  geteuid() to use_terminfo_vars() (patch by Solar Designer
+	  <solar@false.com>).
+	+ improved cygwin terminfo entry, based on patch by
+	  <ernie_boyd@yahoo.com>.
+	+ modify _nc_write_entry() to allow for the possibility that linking
+	  aliases on a filesystem that ignores case would not succeed because
+	  the source and destination differ only by case, e.g., NCR260VT300WPP0
+	  on cygwin (report by Neil Zanella).
+	+ fix a typo in the curs_deleteln.3x man page (patch by Bernhard
+	  Rosenkraenzer <bero@redhat.de>).
+
+20001104
+	+ add configure option --with-ospeed to assist packagers in transition
+	  to 5.3 change to ospeed type.
+	+ add/use CharOf() macro to suppress sign-extension of char type on
+	  platforms where this is a problem in ctype macros, e.g., Solaris.
+	+ change trace output to binary format.
+	+ correct a missing quote adjustment in CF_PATH_SYNTAX autoconf
+	  macro, for OS/2 EMX configuration.
+	+ rearrange a few configure macros, moving preprocessor options to
+	  $CPPFLAGS (a now-obsolete version of autoconf did not consistently
+	  use $CPPFLAGS in both the compile and preprocessor checks).
+	+ add a check in relative_move() to guard against buffer overflow in
+	  the overwrite logic.
+
+20001028
+	+ add message to configure script showing g++ version.
+	+ resync config.guess, config.sub
+	+ modify lib_delwin.c, making it return ERR if the window did not exist
+	  (suggested by Neil Zanella).
+	+ add cases for FreeBSD 3.1 to tdlint and makellib scripts, used this
+	  to test/review ncurses library.  (Would use lclint, but it doesn't
+	  work).
+	+ reorganized knight.c to avoid forward references.  Correct screen
+	  updates when backtracking, especially to the first cell.  Add F/B/a
+	  commands.
+
+20001021 5.2 release for upload to ftp.gnu.org
+	+ update generated html files from manpages.
+	+ modify dist.mk to use edit_man.sh to substitute autoconf'd variables
+	  in html manpages.
+	+ fix an uninitialized pointer in read_termcap.c (report by Todd C
+	  Miller, from report/patch by Philip Guenther <guenther@gac.edu>).
+	+ correct help-message and array limit in knight.c (patch by Brian
+	  Raiter <breadbox@muppetlabs.com>).
+	> patch by Juergen Pfeifer:
+	+ fix to avoid warning by GNAT-3.13p about use of inconsistent casing
+	  for some identifiers defined in the standard package.
+	+ cosmetic change to forms/fty_enum.c
+
+20001014
+	+ correct an off-by-one position in test/railroad.c which could cause
+	  wrapping at the right margin.
+	+ test/repair some issues with libtool configuration.  Make
+	  --disable-echo force libtool --silent.  (Libtool does not work for
+	  OS/2 EMX, works partly for SCO - libtool is still very specific to
+	  gcc).
+	+ change default of --with-manpage-tbl to "no", since for most of the
+	  platforms which do have tbl installed, the system "man" program
+	  understands how to run tbl automatically.
+	+ minor improvement to force_bar() in comp_parse.c (Bernhard
+	  Rosenkraenzer <bero@redhat.de>).
+	+ modify lib_tparm.c to use get_space() before writing terminating
+	  null character, both for consistency as well as to ensure that if
+	  save_char() was called immediately before, that the allocated memory
+	  is enough (patch by Sergei Ivanov).
+	+ add note about termcap ML capability which is duplicated between two
+	  different capabilities:  smgl and smglr (reported by Sergei Ivanov
+	  <svivanov@pdmi.ras.ru>).
+	+ correct parameter counts in include/Caps for dclk as well as some
+	  printer-specific capabilities: csnm, defc, scs, scsd, smgtp, smglp.
+	> patch by Johnny C Lam <lamj@stat.cmu.edu>:
+	+ add support for building with libtool (apparently version 1.3.5,
+	  since old versions do not handle -L../lib), using new configure
+	  option --with-libtool.
+	+ add configure option --with-manpage-tbl, which causes the manpages to
+	  be preprocessed by tbl(1) prior to installation,
+	+ add configure option --without-curses-h, which causes the
+	  installation process to install curses.h as ncurses.h and make
+	  appropriate changes to headers and manpages.
+
+20001009
+	+ correct order of options/parameters in run_tic.in invocation of tic,
+	  which did not work with standard getopt() (reported by Ethan
+	  Butterfield <primus@veris.org>).
+	+ correct logic for 'reverse' variable in lib_vidattr.c, which was
+	  setting it true without checking if newmode had A_REVERSE set, e.g.,
+	  using $TERM=ansi on OS/2 EMX (see 20000917).
+	> patch by Todd C Miller:
+	+ add a few missing use_terminfo_vars() and fixes up _nc_tgetent().
+	  Previously, _nc_cgetset() would still get called on cp so the
+	  simplest thing is to set cp to NULL if !use_terminfo_vars().
+	+ added checks for an empty $HOME environment variable.
+	> patches for OS/2 EMX (Ilya Zakharevich):
+	+ modify convert_configure.pl to support INSTALL.  Change compiler
+	  options in that script to use multithreading, needed for the mouse.
+	+ modify OS/2 mouse support, retrying as a 2-button mouse if code fails
+	  to set up a 3-button mouse.
+	+ improve code for OS/2 mouse support, using _nc_timed_wait() to
+	  replace select() call.
+
+20001007
+	+ change type of ospeed variable back to short to match its use in
+	  legacy applications (reported by Andrey A Chernov).
+	+ add case to configure script for --enable-rpath on IRIX (patch by
+	  Albert Chin-A-Young).
+	+ minor fix to position_check() function, to ensure it gets the whole
+	  cursor report before decoding.
+	+ add configure option --disable-assumed-color, to allow pre-5.1
+	  convention of default colors used for color-pair 0 to be configured
+	  (see assume_default_colors()).
+	+ rename configure option --enable-hashmap --disable-hashmap, and
+	  reorder the configure options, splitting the experimental and
+	  development
+	+ add configure option --disable-root-environ, which tells ncurses to
+	  disregard $TERMINFO and similar environment variables if the current
+	  user is root, or running setuid/setgid (based on discussion with
+	  several people).
+	+ modified misc/run_tic.in to use tic -o, to eliminate dependency on
+	  $TERMINFO variable for installs.
+	+ add table entry for plab_norm to tput, so it passes in strings
+	  for that capability.
+	+ modify parse_format() in lib_tparm.c to ignore precision if it is
+	  longer than 10000 (report by Jouko Pynnonen).
+	+ rewrote limit checks in lib_mvcur.c using new functions
+	  _nc_safe_strcat(), etc.  Made other related changes to check lengths
+	  used for strcat/strcpy (report by Jouko Pynnonen
+	  <jouko@solutions.fi>).
+
+20000930
+	+ modify several descriptions, including those for setaf, setab, in
+	  include/Caps to indicate that the entries are parameterized.  This
+	  information is used to tell which strings are translated when
+	  converting to termcap.  Fixes a problem where the generated termcap
+	  would contain a spurious "%p1" for the terminfo "%p1%d".
+	+ modify ld -rpath options (e.g., Linux, and Solaris) to use an
+	  absolute pathname for the build tree's lib directory (prompted by
+	  discussion with Albert Chin-A-Young).
+	+ modify "make install.man" and "make uninstall.man" to include tack's
+	  man-page.
+	+ various fixes for install scripts used to support configure --srcdir
+	  and --with-install-prefix (reported by Matthew Clarke
+	  <Matthew_Clarke@mindlink.bc.ca>).
+	+ make configure script checks on variables $GCC and $GXX consistently
+	  compare against 'yes' rather than test if they are nonnull, since
+	  either may be set to the corresponding name of the C or C++ compiler
+	  (report/patch by Albert Chin-A-Young).
+
+20000923
+	+ modify rs2 capability in xterm-r6 and similar where cursor
+	  save/restore bracketed the sequence for resetting video attributes.
+	  The cursor restore would undo that (report by John Hawkinson
+	  <jhawk@MIT.EDU> (see NetBSD misc/11052)).
+	+ using parameter check added to tic, corrected 27 typos in
+	  terminfo.src -TD
+	+ modify tic to verify that its inputs are really files, in case
+	  someone tries to read a directory (or /dev/zero).
+	+ add a check for empty buffers returned by fgets() in comp_scan.c
+	  next_char() function, in case tic is run on a non-text file (fixes
+	  a core dump reported by Aaron Campbell <aaron@cs.dal.ca>).
+	+ add to railroad.c some code exercising tgoto(), providing an
+	  alternate form of display if the terminal supports cursor addressing.
+	+ split-out tgoto() again, this time into new file lib_tgoto.c, and
+	  implement a conventional BSD-style tgoto() which is used if the
+	  capability string does not contain terminfo-style padding or
+	  parameters (requested by Andrey A Chernov).
+	+ add check to tic which reports capabilities that do not reference
+	  the expected number of parameters.
+	+ add error checking to infocmp's -v and -m options to ensure that
+	  the option value is indeed a number.
+	+ some cleanup of logic in _nc_signal_handler() to verify if SIGWINCH
+	  handler is setup.  Separated the old/new sigaction data for SIGTSTP
+	  from the other signals.
+
+20000917
+	+ add S0, E0 extensions to screen's terminfo entry, which is another
+	  way to solve the misconfiguration issue -TD
+	+ completed special case for tgoto from 20000916
+
+20000916
+	+ update xterm terminfo entries to match XFree86 xterm patch #146 -TD
+	+ add Matrix Orbital terminfo entries (from Eric Z Ayers
+	  <eric@ale.org>).
+	+ add special case to lib_tparm.c to allow 'screen' program to use a
+	  termcap-style parameter "%." to tgoto() for switching character sets.
+	+ use LN_S substitution in run_tic.in, to work on OS/2 EMX which has
+	  no symbolic links.
+	+ updated notes in README.emx regarding autoconf patches.
+	+ replace a lookup table in lib_vidattr.c used to decode no_color_video
+	  with a logic expression (suggested by Philippe Blain).
+	+ add a/A toggle to ncurses.c 'b' test, which clears/sets alternate
+	  character set attribute from the displayed text.
+	+ correct inequality in parameter analysis of rewritten lib_tparm.c
+	  which had the effect of ignoring p9 in set_attributes (sgr), breaking
+	  alternate character set (reported by Piotr Majka <charvel@link.pl>).
+	+ correct ifdef'ing for GCC_PRINTF, GCC_SCANF which would not compile
+	  with Sun WorkShop compilers since these tokens were empty (cf:
+	  20000902, reported by Albert Chin-A-Young).
+
+20000909
+	+ correct an uninitialized parameter to open_tempfile() in tic.c which
+	  made "tic -I" give an ambiguous error message about tmpnam.
+	+ add special case in lib_vidattr.c to reset underline and standout for
+	  devices that have no sgr0 defined (patch by Don Lewis
+	  <Don.Lewis@tsc.tdk.com>).  Note that this will not work for bold
+	  mode, since there is no exit-bold-mode capability.
+	+ improved patch for Make_Enum_Type (patch by Juergen Pfeifer).
+	+ modify tparm to disallow arithmetic on strings, analyze the varargs
+	  list to read strings as strings and numbers as numbers.
+	+ modify tparm's internal function spop() to treat a null pointer as
+	  an empty string.
+	+ modify tput program so it can be renamed or invoked via a link as
+	  'reset' or 'init', producing the same effect as 'tput reset' or 'tput
+	  init'.
+	+ add private entrypoint _nc_basename(), use to consolidate related
+	  code in progs, as well as accommodating OS/2 EMX pathnames.
+	+ remove NCURSES_CONST line from edit_cfg.sh to compensate for its
+	  removal (except via AC_SUBST) from configure.in, making
+	  --enable-const work again (reported by Juergen Pfeifer).
+	+ regen'd configure to pick up "hpux*" change from 20000902.
+
+20000902
+	+ modify tset.c to check for transformed "reset" program name, if any.
+	+ add a check for null pointer in Make_Enum_Type() (reported by Steven
+	  W Orr <steveo@world.std.com>).
+	+ change functions _nc_parse_entry() and postprocess_termcap() to avoid
+	  using strtok(), because it is non-reentrant (reported by Andrey A
+	  Chernov <ache@nagual.pp.ru>).
+	+ remove "hpux10.*" case from CF_SHARED_OPTS configure script macro.
+	  This differed from the "hpux*" case by using reversed symbolic
+	  links, which made the 5.1 version not match the configuration of
+	  5.0 shared libraries (reported by Albert Chin-A-Young).
+	+ correct a dependency in Ada95/src/Makefile.in which prevented
+	  building with configure --srcdir (patch by H Nanosecond
+	  <aldomel@ix.netcom.com>).
+	+ modify ifdef's in curses.h.in to avoid warning if GCC_PRINTF or
+	  GCC_SCANF was not previously defined (reported by Pavel Roskin
+	  <proski@gnu.org>).
+	+ add MKncurses_def.sh to generate fallback definitions for
+	  ncurses_cfg.h, to quiet gcc -Wundef warnings, modified ifdef's in
+	  code to consistently use "#if" rather than "#ifdef".
+
+20000826
+	+ add QNX qansi entries to terminfo -TD
+	+ add os2 entry to misc/emx.src (<jmcoopr@webmail.bmi.net>).
+	+ add configure option --with-database to allow specifying a different
+	  terminfo source-file to install.  On OS/2 EMX, this defaults to
+	  misc/emx.src
+	+ change misc/run_tic.sh to derive it from misc/run_tic.in, to simplify
+	  setting .exe extension on OS/2 EMX.
+	+ add .exe extension in Ada95/gen/Makefile.in,
+	  Ada95/samples/Makefile.in, for OS/2 EMX (reported by
+	  <jmcoopr@webmail.bmi.net>).
+	+ add configure check for filesystems (such as OS/2 EMX) which do not
+	  distinguish between upper/lowercase filenames, use this to fix tags
+	  rules in makefiles.
+	+ initialize fds[] array to 0's in _nc_timed_wait(); apparently poll()
+	  only sets the revents members of that array when there is activity
+	  corresponding to the related file (report by Glenn Cooper
+	  <gcooper@qantas.com.au>, using Purify on Solaris 5.6).
+	+ change configure script to use AC_CANONICAL_SYSTEM rather than
+	  AC_CANONICAL_HOST, which means that configure --target will set
+	  a default program-prefix.
+	+ add note on cross-compiling to INSTALL (which does not rely on the
+	  AC_CANONICAL_* macros).
+
+20000819
+	+ add cases for EMX OS/2 to config.guess, config.sub
+	+ new version of config.guess, config.sub from lynx 2.8.4dev.7
+	+ add definitions via transform.h to allow tic and tput to check for
+	  the transformed aliases rather than the original infotocap, etc.
+	+ simplify transform-expressions in progs/Makefile.in, make the
+	  uninstall rule work for transformed program names.
+	+ change symbol used by --install-prefix configure option from
+	  INSTALL_PREFIX to DESTDIR (the latter has become common usage
+	  although the name is misleading).
+	+ modify programs to use curses_version() string to report the version
+	  of ncurses with which they are compiled rather than the
+	  NCURSES_VERSION string.  The function returns the patch level in
+	  addition to the major and minor version numbers.
+
+20000812
+	+ modify CF_MAN_PAGES configure macro to make transformed program names
+	  a parameter to that macro rather than embedding them in the macro.
+	+ newer config.guess, config.sub (reference version used in lynx
+	  2.8.4dev.7).
+	+ add configure option --with-default-terminfo-dir=DIR to allow
+	  specifying the default terminfo database directory (request by Albert
+	  Chin-A-Young).
+	+ minor updates for terminfo.src from FreeBSD termcap change-history.
+	+ correct notes in README and INSTALL regarding documentation files
+	  that were moved from misc directory to doc (report by Rich Kulawiec
+	  <rsk@gsp.org>).
+	+ change most remaining unquoted parameters of 'test' in configure
+	  script to use quotes, for instance fixing a problem in the
+	  --disable-database option (reported by Christian Mondrup
+	  <scancm@biobase.dk>).
+	+ minor adjustments to work around some of the incompatibilities/bugs
+	  in autoconf 2.29a alpha.
+	+ add -I/usr/local/include when --with-ncurses option is used in
+	  test/configure script.
+	+ correct logic in adjust_cancels(), which did not check both
+	  alternatives when reclassifying an extended name between boolean,
+	  number and string, causing an infinite loop in tic.
+
+20000730
+	+ correct a missing backslash in curses.priv.h
+
+20000729
+	+ change handling of non_dest_scroll_region in tty_update.c to clear
+	  text after it is shifted in rather than before shifting out.  Also
+	  correct row computation (reported by Ruediger Kuhlmann
+	  <uck4@rz.uni-karlsruhe.de>).
+	+ add/use new trace function to display chtype values from winch() and
+	  getbkgd().
+	+ add trace mask TRACE_ATTRS, alter several existing _tracef calls that
+	  trace attribute changes under TRACE_CALLS to use this.
+	+ modify MKlib_gen.sh so that functions returning chtype will call
+	  returnChar().
+	+ add returnChar() trace, for functions returning chtype.
+	+ change indent.pro to line up parenthesis.
+
+20000722
+	+ fix a heap problem with the c++ binding (report by
+	  <alexander_liberson@ninewest.com>, patch by Juergen Pfeifer).
+	+ minor adjustment to ClrToEOL() to handle an out-of-bounds parameter.
+	+ modify the check for big-core to force a couple of memory accesses,
+	  which may work as needed for older/less-capable machines (if not,
+	  there's still the explicit configure option).
+	> fixes based on diff's for Amiga and BeOS found at
+	  http://www.mathematik.uni-karlsruhe.de/~kuhlmann/cross/ncurses/
+	+ alter definition of NCURSES_CONST to make it non-empty.
+	+ add amiga-vnc terminfo entry.
+	+ redefine 'TEXT' in menu.h for AMIGA, since it is reported to have
+	  an (unspecified) symbol conflict.
+	+ replaced case-statement in _nc_tracebits() for CSIZE with a table to
+	  simplify working around implementations that define random
+	  combinations of the related macros to zero.
+	+ modify configure test for tcgetattr() to allow for old
+	  implementations, e.g., on BeOS, which only defined it as a macro.
+	> patches by Bruno Haible:
+	+ when checking LC_ALL/LC_CTYPE/LANG environment variables for UTF-8
+	  locale, ignore those which are set to an empty value, as per SUSV2.
+	+ encode 0xFFFD in UTF-8 with 3 bytes, not 2.
+	+ modify _nc_utf8_outch() to avoid sign-extension when checking for
+	  out-of-range value.
+
+20000715
+	+ correct manlinks.sed script to avoid using ERE "\+", which is not
+	  understood by older versions of sed (patch by Albert Chin-A-Young).
+	+ implement configure script options that transform installed program
+	  names, e.g., --program-prefix, including the manpage names and cross
+	  references (patch by Albert Chin-A-Young <china@thewrittenword.com>).
+	+ correct several mismatches between manpage filename and ".TH"
+	  directives, renaming dft_fgbg.3x to default_colors.3x and
+	  menu_attribs.3x to menu_attributes.3x (report by Todd C Miller).
+	+ correct missing includes for <string.h> in several places, including
+	  the C++ binding.  This is not noted by gcc unless we use the
+	  -fno-builtin option (reported by Igor Schein <igor@txc.com>).
+	+ modified progs/tset.c and tack/sysdep.c to build with sgttyb
+	  interface if neither termio or termios is available.  Tested this
+	  with FreeBSD 2.1.5 (which does have termios - but the sgttyb does
+	  work).
+
+20000708 5.1 release for upload to ftp.gnu.org
+	+ document configure options in INSTALL.
+	+ add man-page for ncurses trace functions.
+	+ correct return value shown in curs_touch.3x for is_linetouched() and
+	  is_wintouched(), in curs_initscr.3x for isendwin(), and in
+	  curs_termattr.3x for has_ic() and has_il().
+	+ add prototypes for touchline() and touchwin(), adding them to the
+	  list of generated functions.
+	+ modify fifo_push() to put ERR into the fifo just like other values to
+	  return from wgetch().  It was returning without doing that, making
+	  end-of-file condition incorrectly return a 0 (reported by Todd C
+	  Miller).
+	+ uncomment CC_SHARED_OPTS for progs and tack (see 971115), since they
+	  are needed for SCO OpenServer.
+	+ move _nc_disable_period from free_ttype.c to comp_scan.c to appease
+	  dynamic loaders on SCO and IRIX64.
+	+ add "-a" option to test/ncurses.c to invoke assume_default_colors()
+	  for testing.
+	+ correct assignment in assume_default_colors() which tells ncurses
+	  whether to use default colors, or the assumed ones (reported by Gary
+	  Funck <gary@Intrepid.Com>).
+	+ review/correct logic in mk-1st.awk for making symbolic links for
+	  shared libraries, in particular for FreeBSD, etc.
+	+ regenerate misc/*.def files for OS/2 EMX dll's.
+	+ correct quoting of values for CC_SHARED_OPTS in aclocal.m4 for
+	  cases openbsd2*, openbsd*, freebsd* and netbsd* (patch by Peter
+	  Wemm) (err in 20000610).
+	+ minor updates to release notes, as well as adding/updating URLs for
+	  examples cited in announce.html
+	> several fixes from Philippe Blain <philippe.blain2@freesbee.fr>:
+	+ correct placement of ifdef for NCURSES_XNAMES in function
+	  _nc_free_termtype(), fixes a memory leak.
+	+ add a call to _nc_synchook() to the end of function whline() like
+	  that in wvline() (difference was in 1.9.4).
+	+ make ClearScreen() a little faster by moving two instances of
+	  UpdateAttr() out of for-loops.
+	+ simplify ClrBottom() by eliminating the tstLine data, using for-loops
+	  (cf: 960428).
+
+20000701 pre-release
+	+ change minor version to 1, i.e., ncurses 5.1
+	+ add experimental configure option --enable-colorfgbg to check for
+	  $COLORFGBG variable as set by rxvt/aterm/Eterm.
+	+ add Eterm terminfo entry (Michael Jennings <mej@valinux.com>).
+	+ modify manlinks.sed to pick aliases from the SYNOPSIS section, and
+	  several manpages so manlinks.sed can find aliases for creating
+	  symbolic links.
+	+ add explanation to run_tic.sh regarding extended terminal
+	  capabilities.
+	+ change message format for edit_cfg.sh, since some people interpret
+	  it as a warning.
+	+ correct unescaped '$' in sysv5uw7*|unix_sv* rule for CF_SHARED_OPTS
+	  configure macro (report by Thanh Ma <Thanh.Ma@casi-rusco.com>).
+	+ correct logic in lib_twait.c as used by lib_mouse.c for GPM mouse
+	  support when poll() is used rather than select() (prompted by
+	  discussion with David Allen <DAllen24@aol.com>).
+
+20000624 pre-release
+	+ modify TransformLine() to check for cells with different color pairs
+	  that happen to render the same display colors.
+	+ apply $NCURSES_NO_PADDING to cost-computation in mvcur().
+	+ improve cost computation in PutRange() by accounting for the use
+	  of parm_right_cursor in mvcur().
+	+ correct cost computation in EmitRange(), which was not using the
+	  normalized value for cursor_address.
+	+ newer config.guess, config.sub (reference version used in TIN 1.5.6).
+
+20000617
+	+ update config.guess, config.sub (reference version used in PCRE 3.2).
+	+ resync changes to gnathtml against version 1.22, regenerated html
+	  files under doc/html/ada using this (1.22.1.1).
+	+ regenerated html files under doc/html/man after correcting top and
+	  bottom margin options for man2html in dist.mk
+	+ minor fixes to test programs ncurses 'i' and testcurs program to make
+	  the subwindow's background color cover the subwindow.
+	+ modify configure script so AC_MSG_ERROR is temporarily defined to a
+	  warning in AC_PROG_CXX to make it recover from a missing C++ compiler
+	  without requiring user to add --without-cxx option (adapted from
+	  comment by Akim Demaille <akim@epita.fr> to autoconf mailing list).
+	+ modify headers.sh to avoid creating temporary files in the build
+	  directory when installing headers (reported by Sergei Pokrovsky
+	  <pok@nbsp.nsk.su>)
+
+20000610
+	+ regenerated the html files under doc/html/ada/files and
+	  doc/html/ada/funcs with a slightly-improved gnathtml.
+	+ add kmous capability to linux terminfo entry to allow it to use
+	  xterm-style events provided by gpm patch by Joerg Schoen.
+	+ make the configure macro CF_SHARED_OPTS a little smarter by testing
+	  if -fPIC is supported by gcc rather than -fpic.  The former option
+	  allows larger symbol tables.
+	+ update config.guess and config.sub (patches by
+	  Kevin Buettner <kev@primenet.com> (for elf64_ia64),
+	  Bernd Kuemmerlen <bkuemmer@mevis.de> (for MacOS X)).
+	+ add warning for 'tic -cv' about use of '^?' in terminfo source, which
+	  is an extension.
+
+20000527
+	+ modify echo() behavior of getch() to match Solaris curses for
+	  carriage return and backspace (reported by Neil Zanella).
+	+ change _nc_flush() to a function.
+	+ modify delscreen() to check if the output stream has been closed, and
+	  if so, free the buffer allocated for setbuf (this provides an
+	  ncurses-specific way to avoid a memory leak when repeatedly calling
+	  newterm reported by Chipp C <at_1@zdnetonebox.com>).
+	+ correct typo in curs_getch.3x manpage regarding noecho (reported by
+	  David Malone <dwmalone@maths.tcd.ie>).
+	+ add a "make libs" rule.
+	+ make the Ada95 interface build with configure --enable-widec.
+	+ if the configure --enable-widec option is given, append 'w' to names
+	  of the generated libraries (e.g., libncursesw.so) to avoid conflict
+	  with existing ncurses libraries.
+
+20000520
+	+ modify view.c to make a rudimentary viewer of UTF-8 text if ncurses
+	  is configured with the experimental wide-character support.
+	+ add a simple UTF-8 output driver to the experimental wide-character
+	  support.  If any of the environment variables LC_ALL, LC_CTYPE or
+	  LANG contain the string "UTF-8", this driver will be used to
+	  translate the output to UTF-8.  This works with XFree86 xterm.
+	+ modify configure script to allow building shared libraries on BeOS
+	  (from a patch by Valeriy E Ushakov).
+	+ modify lib_addch.c to allow repeated update to the lower-right
+	  corner, rather than displaying only the first character written until
+	  the cursor is moved.  Recent versions of SVr4 curses can update the
+	  lower-right corner, and behave this way (reported by Neil Zanella).
+	+ add a limit-check in _nc_do_color(), to avoid using invalid color
+	  pair value (report by Brendan O'Dea <bod@compusol.com.au>).
+
+20000513
+	+ the tack program knows how to use smcup and rmcup but the "show caps
+	  that can be tested" feature did not reflect this knowledge.  Correct
+	  the display in the menu tack/test/edit/c (patch by Daniel Weaver).
+	+ xterm-16color does allow bold+colors, removed ncv#32 from that
+	  terminfo entry.
+
+20000506
+	+ correct assignment to SP->_has_sgr_39_49 in lib_dft_fgbg.c, which
+	  broke check for screen's AX capability (reported by Valeriy E Ushakov
+	  <uwe@ptc.spbu.ru>).
+	+ change man2html rule in dist.mk to workaround bug in some
+	  man-programs that ignores locale when rendering hyphenation.
+	+ change web- and ftp-site to dickey.his.com
+
+20000429
+	+ move _nc_curr_token from parse_entry.c to comp_scan.c, to work around
+	  problem linking tack on MacOS X DP3.
+	+ include <sys/time.h> in lib_napms.c to compile on MacOS X DP3
+	  (reported by Gerben Wierda <wierda@holmes.nl>).
+	+ modify lib_vidattr.c to check for ncv fixes when pair-0 is not
+	  default colors.
+	+ add -d option to ncurses.c, to turn on default-colors for testing.
+	+ add a check to _nc_makenew() to ensure that newwin() and newpad()
+	  calls do not silently fail by passing too-large limits.
+	+ add symbol NCURSES_SIZE_T to use rather than explicit 'short' for
+	  internal window and pad sizes.  Note that since this is visible in
+	  the WINDOW struct, it would be an ABI change to make this an 'int'
+	  (prompted by a question by Bastian Trompetter
+	  <btrompetter@firemail.de>, who attempted to create a 96000-line pad).
+
+20000422
+	+ add mgterm terminfo entry from NetBSD, minor adjustments to sun-ss5,
+	  aixterm entries -TD
+	+ modify tack/ansi.c to make it more tolerant of bad ANSI replies.  An
+	  example of an illegal ANSI resonse can be found using Microsoft's
+	  Telnet client.  A correct display can be found using a VT-4xx
+	  terminal or XFree86 xterm with:
+		XTerm*VT100*decTerminalID:  450
+	  (patch by Daniel Weaver).
+	+ modify gdc.c to recognize 'q' for quit, 's' for single-step and ' '
+	  for resume.  Add '-n' option to force gdc's standard input to
+	  /dev/null, to both illustrate the use of newterm() for specifying
+	  alternate inputs as well as for testing signal handling.
+	+ minor fix for configure option --with-manpage-symlinks, for target
+	  directories that contain a period ('.') (reported by Larry Virden).
+
+20000415
+	+ minor additions to beterm entry (feedback from Rico Tudor) -TD
+	+ corrections/updates for some IBM terminfo entries -TD
+	+ modify _nc_screen_wrap() so that when exiting curses mode with
+	  non-default colors, the last line on the screen will be cleared to
+	  the screen's default colors (request by Alexander V Lukyanov).
+	+ modify ncurses.c 'r' example to set nonl(), allowing control/M to be
+	  read for demonstrating the REQ_NEW_LINE operation (prompted by a
+	  question by Tony L Keith <tlkeith@keithconsulting.com>).
+	+ modify ncurses.c 'r' example of field_info() to work on Solaris 2.7,
+	  documented extension of ncurses which allows a zero pointer.
+	+ modify fmt_complex() to avoid buffer overflow in case of excess
+	  recursion, and to recognize "%e%?" as a synonym for else-if, which
+	  means that it will not recur for that special case.
+	+ add logic to support $TERMCAP variable in case the USE_GETCAP symbol
+	  is defined (patch by Todd C Miller).
+	+ modify one of the m4 files used to generate the Ada95 sources,
+	  to avoid using the token "symbols" (patch by Juergen Pfeifer).
+
+20000408
+	+ add terminfo entries bsdos-pc-m, bsdos-pc-mono (Jeffrey C Honig)
+	+ correct spelling error in terminfo entry name:  bq300-rv was given as
+	  bg300-rv in esr's version.
+	+ modify redrawwin() macro so its parameter is fully parenthesized
+	  (fixes Debian #61088).
+	+ correct formatting error in dump_entry() which set incorrect column
+	  value when no newline trimming was needed at the end of an entry,
+	  before appending "use=" clauses (cf: 960406).
+
+20000401
+	+ add configure option --with-manpage-symlinks
+	+ change unctrl() to render C1 characters (128-159) as ~@, ~A, etc.
+	+ change makefiles so trace() function is provided only if TRACE is
+	  defined, e.g., in the debug library.  Modify related calls to
+	  _tracechar() to use unctrl() instead.
+
+20000325
+	+ add screen's AX capability (for ECMA SGR 39 and 49) to applicable
+	  terminfo entries, use presence of this as a check for a small
+	  improvement in setting default colors.
+	+ improve logic in _nc_do_color() implementing assume_default_colors()
+	  by passing in previous color pair info to eliminate redundant call to
+	  set_original_colors().  (Part of this is from a patch by Alexander
+	  V Lukyanov).
+	+ modify warning in _nc_trans_string() about a possibly too-long string
+	  to do this once only rather than for each character past the
+	  threshold (600).  Change interface of _nc_trans_string() to allow
+	  check for buffer overflow.
+	+ correct use of memset in _nc_read_entry_source() to initialize ENTRY
+	  struct each time before reading new data into it, rather than once
+	  per loop (cf:  990301).  This affects multi-entry in-core operations
+	  such as "infocmp -Fa".
+
+20000319
+	+ remove a spurious pointer increment in _nc_infotocap() changes from
+	  20000311.  Add check for '.' in format of number, since that also
+	  is not permitted in termcap.
+	+ correct typo in rxvt-basic terminfo from temporary change made while
+	  integrating 20000318.
+
+20000318
+	+ revert part of the vt220 change (request by Todd C Miller).
+	+ add ansi-* terminfo entries from ESR's version.
+	+ add -a option to tic and infocmp, which retains commented-out
+	  capabilities during source translation/comparison, e.g., captoinfo
+	  and infotocap.
+	+ modify cardfile.c to display an empty card if no input data file is
+	  found, fixes a core dump in that case (reported by Bruno Haible).
+	+ correct bracketing in CF_MATH_LIB configure macro, which gave wrong
+	  result for OS/2 EMX.
+	+ supply required parameter for _nc_resolve_uses() call in
+	  read_termcap.c, overlooked in 20000311 (reported by Todd C Miller).
+	> patches by Bruno Haible <haible@ilog.fr>:
+	+ fix a compiler warning in fty_enum.c
+	+ correct LIB_PREFIX expression for DEPS_CURSES in progs, tack
+	  makefiles, which resulted in redundant linking (cf: 20000122).
+
+20000311
+	+ make ifdef's for BROKEN_LINKER consistent (patch by Todd C Miller).
+	+ improved tack/README (patch by Daniel Weaver).
+	+ modify tput.c to ensure that unspecified parameters are passed to
+	  tparm() as 0's.
+	+ add a few checks in infocmp to guard against buffer overflow when
+	  displaying string capabilities.
+	+ add check for zero-uses in infocmp's file_comparison() function
+	  before calling _nc_align_termtype().  Otherwise one parameter is
+	  indexed past the end of the uses-array.
+	+ add an option -q to infocmp to specify the less verbose output,
+	  keeping the existing format as the default, though not retaining the
+	  previous behavior that made the -F option compare each entry to
+	  itself.
+	+ adapted patch by ESR to make infocmp -F less verbose -TD
+	  (the submitted patch was unusable because it did not compile
+	  properly)
+	  + modify write_entry.c to ensure that absent or cancelled booleans
+	    are written as FALSE, for consistency with infocmp which now
+	    assumes this.  Note that for the small-core configuration, tic
+	    may not produce the same result as before.
+	  + change some private library interfaces used by infocmp, e.g.,
+	    _nc_resolve_uses().
+	  + add a check in _nc_infotocap() to ensure that cm-style capabilities
+	    accept only %d codes when converting the format from terminfo to
+	    termcap.
+	  + modify ENTRY struct to separate the data in 'parent' into the name
+	    and link values (the original idea to merge both into 'parent' was
+	    not good).
+	  + discard repair_acsc(tterm);
+	> patch by Juergen Pfeifer:
+	+ drop support for gnat 3.10
+	+ move generated documentation and html files under ./doc directory,
+	  adding makefile rules for this to dist.mk
+
+20000304
+	+ correct conflicting use of tparm() in 20000226 change to tic, which
+	  made it check only one entry at a time.
+	+ fix errors in ncurses-intro.html and hackguide.html shown by Dave
+	  Raggett's tidy.
+	+ make the example in ncurses-intro.html do something plausible, and
+	  corrected misleading comment (reported by Neil Zanella).
+	+ modify pnoutrefresh() to set newscr->_leaveok as wnoutrefresh() does,
+	  to fix a case where the cursor position was not updated as in
+	  Solaris  (patch by David Mosberger <davidm@hpl.hp.com>).
+	+ add a limit-check for wresize() to ensure that a subwindow does not
+	  address out of bounds.
+	+ correct offsets used for subwindows in wresize() (patch by Michael
+	  Andres <ma@suse.de>).
+	+ regenerate html'ized manual pages with man2html 3.0.1 (patch by
+	  Juergen Pfeifer).  This generated a file with a space in its name,
+	  which I removed.
+	+ fix a few spelling errors in tack.
+	+ modify tack/Makefile.in to match linker options of progs/Makefile.in;
+	  otherwise it does not build properly for older HPUX shared library
+	  configurations.
+	+ add several terminfo entries from esr's "11.0".
+
+20000226
+	+ make 'tput flash' work properly for xterm by flushing output in
+	  delay_output() when using napms(), and modifying xterm's terminfo to
+	  specify no padding character.  Otherwise, xterm's reported baud rate
+	  can mislead ncurses into producing too few padding characters
+	  (Debian #58530).
+	+ add a check to tic for consistency between sgr and the separate
+	  capabilities such as smso, use this to check/correct several
+	  terminfo entries (Debian #58530).
+	+ add a check to tic if cvvis is the same as cnorm, adjusted several
+	  terminfo entries to remove the conflict (Debian #58530).
+	+ correct prototype shown in attr_set()/wattr_set() manpages (fixes
+	  Debian #53962).
+	+ minor clarification for curs_set() and leaveok() manpages.
+	+ use mkstemp() for creating temporary file for tic's processing of
+	  $TERMCAP contents (fixes Debian #56465).
+	+ correct two errors from integrating Alexander's changes:  did not
+	  handle the non-bce case properly in can_erase_with() (noted by
+	  Alexander), and left fg/bg uninitialized in the pair-zero case of
+	  _nc_do_color() (reported by Dr Werner Fink <werner@suse.de> and
+	  Ismael Cordeiro <ismael@cordeiro.com>).
+
+20000219
+	+ store default-color code consistently as C_MASK, even if given as
+	  -1 for convenience (adapted from patches by Alexander V Lukyanov).
+	> patches by Alexander V Lukyanov:
+	+ change can_clear_with() macro to accommodate logic for
+	  assume_default_colors(), making most of the FILL_BCE logic
+	  unnecessary.  Made can_clear_with() an inline function to make it
+	  simpler to read.
+
+20000212
+	+ corrected form of recent copyright dates.
+	+ minor corrections to xterm-xf86-v333 terminfo entry -TD
+	> patches by Alexander V Lukyanov:
+	+ reworded dft_fgbg.3x to avoid assuming that the terminal's default
+	  colors are white on black.
+	+ fix initialization of tstLine so that it is filled with current blank
+	  character in any case.  Previously it was possible to have it filled
+	  with old blank.  The wrong over-optimization was introduced in 991002
+	  patch.  (it is not very critical as the only bad effect is not using
+	  clr_eos for clearing if blank has changed).
+
+20000205
+	+ minor corrections/updates to several terminfo entries: rxvt-basic,
+	  vt520, vt525, ibm5151, xterm-xf86-v40 -TD
+	+ modify ifdef's for poll() to allow it to use <sys/poll.h>, thereby
+	  allowing poll() to be used on Linux.
+	+ add CF_FUNC_POLL macro to check if poll() is able to select from
+	  standard input.  If not we will not use it, preferring select()
+	  (adapted from patch by Michael Pakovic <mpakovic@fdn.com>).
+	+ update CF_SHARED_OPTS macro for SCO Unixware 7.1 to allow building
+	  shared libraries (reported/tested by Thanh <thanhma@mediaone.net>).
+	+ override $LANGUAGE in build to avoid incorrect ordering of keynames.
+	+ correct CF_MATH_LIB parameter, must be sin(x), not sqrt(x).
+
+20000122
+	+ resync CF_CHECK_ERRNO and CF_LIB_PREFIX macros from tin and xterm -TD
+	+ modify CF_MATH_LIB configure macro to parameterize the test function
+	  used, for reuse in dialog and similar packages.
+	+ correct tests for file-descriptors in OS/2 EMX mouse support.  A
+	  negative value could be used by FD_SET, causing the select() call
+	  to wait indefinitely.
+
+20000115
+	+ additional fixes for non-bce terminals (handling of delete_character)
+	  to work when assume_default_colors() is not specified.
+	+ modify warning message from _nc_parse_entry() regarding extended
+	  capability names to print only if tic/infocmp/toe have the -v flag
+	  set, and not at all in ordinary user applications.  Otherwise, this
+	  warning would be shown for screen's extended capabilities in programs
+	  that use the termcap interface (reported by Todd C Miller).
+	+ modify use of _nc_tracing from programs such as tic so their debug
+	  level is not in the same range as values set by trace() function.
+	+ small panel header cleanup (patch by Juergen Pfeifer).
+	+ add 'railroad' demo for termcap interface.
+	+ modify 'tic' to write its usage message to stderr (patch by Todd C
+	  Miller).
+
+20000108
+	+ add prototype for erase() to curses.h.in, needed to make test
+	  programs build with c++/g++.
+	+ add .c.i and .c.h suffix rules to generated makefiles, for debugging.
+	+ correct install rule for tack.1; it assumed that file was in the
+	  current directory (reported by Mike Castle <dalgoda@ix.netcom.com>).
+	+ modify terminfo/termcap translation to suppress acsc before trying
+	  sgr if the entry would be too large (patch by Todd C Miller).
+	+ document a special case of incompatibility between ncurses 4.2 and
+	  5.0, add a section for this in INSTALL.
+	+ add TRACE_DATABASE flag for trace().
+
+20000101
+	+ update mach, add mach-color terminfo entries based on Debian diffs
+	  for ncurses 5.0 -TD
+	+ add entries for xterm-hp, xterm-vt220, xterm-vt52 and xterm-noapp
+	  terminfo entries -TD
+	+ change OTrs capabilities to rs2 in terminfo.src -TD
+	+ add obsolete and extended capabilities to 'screen' terminfo -TD
+	+ corrected conversion from terminfo rs2 to termcap rs (cf: 980704)
+	+ make conversion to termcap ug (underline glitch) more consistently
+	  applied.
+	+ fix out-of-scope use of 'personal[]' buffer in 'toe' (this error
+	  was in the original pre-1.9.7 version, when $HOME/.terminfo was
+	  introduced).
+	+ modify 'toe' to ignore terminfo directories to which it has no
+	  permissions.
+	+ modify read_termtype(), fixing 'toe', which could dump core when it
+	  found an incomplete entry such as "dumb" because it did not
+	  initialize its buffer for _nc_read_file_entry().
+	+ use -fPIC rather than -fpic for shared libraries on Linux, not
+	  needed for i386 but some ports (from Debian diffs for 5.0) -TD
+	+ use explicit VALID_NUMERIC() checks in a few places that had been
+	  overlooked, and add a check to ensure that init_tabs is nonzero,
+	  to avoid divide-by-zero (reported by Todd C Miller).
+	+ minor fix for CF_ANSI_CC_CHECK configure macro, for HPUX 10.x (from
+	  tin) -TD
+
+19991218
+	+ reorder tests during mouse initialization to allow for gpm to run in
+	  xterm, or for xterm to be used under OS/2 EMX.  Also drop test for
+	  $DISPLAY in favor of kmous=\E[M or $TERM containing "xterm" (report
+	  by Christian Weisgerber <naddy@mips.rhein-neckar.de>).
+	+ modify raw() and noraw() to clear/restore IEXTEN flag which affects
+	  stty lnext on systems such as FreeBSD (report by Bruce Evans
+	  <bde@zeta.org.au>, via Jason Evans <jasone@canonware.com>).
+	+ fix a potential (but unlikely) buffer overflow in failed() function
+	  of tset.c (reported by Todd C Miller).
+	+ add manual-page for ncurses extensions, documented curses_version(),
+	  use_extended_names().
+
+19991211
+	+ treat as untranslatable to termcap those terminfo strings which
+	  contain non-decimal formatting, e.g., hexadecimal or octal.
+	+ correct commented-out capabilities that cannot be translated to
+	  termcap, which did not check if a colon must be escaped.
+	+ correct termcap translation for "%>" and "%+", which did not check
+	  if a colon must be escaped, for instance.
+	+ use save_string/save_char for _nc_captoinfo() to eliminate fixed
+	  buffer (originally for _nc_infotocap() in 960301 -TD).
+	+ correct expression used for terminfo equivalent of termcap %B,
+	  adjust regent100 entry which uses this.
+	+ some cleanup and commenting of ad hoc cases in _nc_infotocap().
+	+ eliminate a fixed-buffer in tic, used for translating comments.
+	+ add manpage for infotocap
+
+19991204
+	+ add kvt and gnome terminfo entries -TD
+	+ correct translation of "%%" by infotocap, which was emitted as "%".
+	+ add "obsolete" termcap strings to terminfo.src
+	+ modify infocmp to default to showing obsolete capabilities rather
+	  than terminfo only.
+	+ modify write_entry.c so that if extended names (i.e., configure
+	  --enable-tcap-names) are active, then tic will also write "obsolete"
+	  capabilities that are present in the terminfo source.
+	+ modify tic so that when running as captoinfo or infotocap, it
+	  initializes the output format as in -C and -I options, respectively.
+	+ improve infocmp and tic -f option by splitting long strings that do
+	  not have if-then-else construct, but do have parameters, e.g., the
+	  initc for xterm-88color.
+	+ refine MKtermsort.sh slightly by using bool for the *_from_termcap
+	  arrays.
+
+19991127
+	+ additional fixes for non-bce terminals (handling of clear_screen,
+	  clr_eol, clr_eos, scrolling) to work when assume_default_colors() is
+	  not specified.
+	+ several small changes to xterm terminfo entries -TD.
+	+ move logic for _nc_windows in lib_freeall.c inside check for nonnull
+	  SP, since it is part of that struct.
+	+ remove obsolete shlib-versions, which was unintentionally re-added
+	  in 970927.
+	+ modify infocmp -e, -E options to ensure that generated fallback.c
+	  type for Booleans agrees with term.h (reported by Eric Norum
+	  <eric@cls.usask.ca>).
+	+ correct configure script's use of $LIB_PREFIX, which did not work
+	  for installing the c++ directory if $libdir did not end with "/lib"
+	  (reported by Huy Le <huyle@ugcs.caltech.edu>).
+	+ modify infocmp so -L and -f options work together.
+	+ modify the initialization of SP->_color_table[] in start_color() so
+	  that color_content() will return usable values for COLORS greater
+	  than 8.
+	+ modify ncurses 'd' test in case COLORS is greater than 16, e.g., for
+	  xterm-88color, to limit the displayed/computed colors to 16.
+	> patch by Juergen Pfeifer:
+	+ simplify coding of the panel library according to suggestions by
+	  Philippe Blain.
+	+ improve macro coding for a few macros in curses.priv.h
+
+19991113
+	+ modify treatment of color pair 0 so that if ncurses is configured
+	  to support default colors, and they are not active, then ncurses
+	  will set that explicitly, not relying on orig_colors or orig_pair.
+	+ add new extension, assume_default_colors() to provide better control
+	  over the use of default colors.
+	+ modify test programs to use more-specific ifdef's for existence of
+	  wresize(), resizeterm() and use_default_colors().
+	+ modify configure script to add specific ifdef's for some functions
+	  that are included when --enable-ext-funcs is in effect, so their
+	  existence can be ifdef'd in the test programs.
+	+ reorder some configure options, moving those extensions that have
+	  evolved from experimental status into a new section.
+	+ change configure --enable-tcap-names to enable this by default.
+
+19991106
+	+ install tack's manpage (reported by Robert Weiner
+	  <robert@progplus.com>)
+	+ correct worm.c's handling of KEY_RESIZE (patch by Frank Heckenbach).
+	+ modify curses.h.in, undef'ing some symbols to avoid conflict with C++
+	  STL (reported by Matt Gerassimoff <mgeras@ticon.net>)
+
+19991030
+	+ modify linux terminfo entry to indicate that dim does not mix with
+	  color (reported by Klaus Weide <kweide@enteract.com>).
+	+ correct several typos in terminfo entries related to missing '['
+	  in CSI's -TD
+	+ fix several compiler warnings in c++ binding (reported by Tim
+	  Mooney for alphaev56-dec-osf4.0f
+	+ rename parameter of _nc_free_entries() to accommodate lint.
+	+ correct lint rule for tack, used incorrect list of source files.
+	+ add case to config.guess, config.sub for Rhapsody.
+	+ improve configure tests for libg++ and libstdc++ by omitting the
+	  math library (which is missing on Rhapsody), and improved test for
+	  the math library itself (adapted from path by Nelson H. F. Beebe).
+	+ explicitly initialize to zero several data items which were
+	  implicitly initialized, e.g., cur_term.  If not explicitly
+	  initialized, their storage type is C (common), and causes problems
+	  linking on Rhapsody 5.5 using gcc 2.7.2.1 (reported by Nelson H. F.
+	  Beebe).
+	+ modify Ada95 binding to not include the linker option for Ada
+	  bindings in the Ada headers, but in the Makefiles instead (patch by
+	  Juergen Pfeifer).
+
+19991023 5.0 release for upload to ftp.gnu.org
+	+ effective with release of 5.0, change NCURSES_VERSION_PATCH to
+	  4-digit year.
+	+ add function curses_version(), to return ncurses library version
+	  (request by Bob van der Poel).
+	+ remove rmam, smam from cygwin terminfo entry.
+	+ modify FreeBSD cons25 terminfo entry to add cnorm and cvvis, as well
+	  as update ncv to indicate that 'dim' conflicts with colors.
+	+ modify configure script to use symbolic links for FreeBSD shared
+	  libraries by default.
+	+ correct ranf() function in rain and worm programs to ensure it does
+	  not return 1.0
+	+ hide the cursor in hanoi.c if it is running automatically.
+	+ amend lrtest.c to account for optimizations that exploit margin
+	  wrapping.
+	+ add a simple terminfo demo, dots.c
+	+ modify SIGINT/SIGQUIT handler to set a flag used in _nc_outch() to
+	  tell it to use write() rather than putc(), since the latter is not
+	  safe in a signal handler according to POSIX.
+	+ add/use internal macros _nc_flush() and NC_OUTPUT to hide details
+	  of output-file pointer in ncurses library.
+	+ uncomment CC_SHARED_OPTS (see 971115), since they are needed for SCO
+	  OpenServer.
+	+ correct CC_SHARED_OPTS for building shared libraries for SCO
+	  OpenServer.
+	+ remove usleep() from alternatives in napms(), since it may interact
+	  with alarm(), causing a process to be interrupted by SIGALRM (with
+	  advice from Bela Lubkin).
+	+ modify terminal_interface-curses-forms.ads.m4 to build/work with
+	  GNAT 3.10 (patch by Juergen Pfeifer).
+	+ remove part of CF_GPP_LIBRARY configure-script macro, which did not
+	  work with gcc 2.7.2.3
+	+ minor fix to test/tclock.c to avoid beeping more than once per second
+	+ add 's' and ' ' decoding to test/rain.c
+
+991016	pre-release
+	+ corrected BeOS code for lib_twait.c, making nodelay() function work.
+
+991009	pre-release
+	+ correct ncurses' value for cursor-column in PutCharLR(), which was
+	  off-by-one in one case (patch by Ilya Zakharevich).
+	+ fix some minor errors in position_check() debugging code, found while
+	  using this to validate the PutCharLR() patch.
+	+ modify firework, lrtest, worm examples to be resizable, and to
+	  recognize 'q' for quit, 's' for single-step and ' ' for resume.
+	+ restore reverted change to  terminal_interface-curses-forms.ads.m4,
+	  add a note on building with gnat 3.10p to Ada95/TODO.
+	+ add a copy of the standalone configure script for the test-directory
+	  to simplify testing on SCO and Solaris.
+
+991002	pre-release
+	+ minor fixes for _nc_msec_cost(), color_content(), pair_content(),
+	  _nc_freewin(), ClrBottom() and onscreen_mvcur() (analysis by Philippe
+	  Blain, comments by Alexander V Lukyanov).
+	+ simplify definition of PANEL and eliminate internal functions
+	  _nc_calculate_obscure(), _nc_free_obscure() and _nc_override(),
+	  (patch by Juergen Pfeifer, analysis by Philippe Blain
+	  <bledp@voila.fr>)).
+	+ change renaming of dft_fgbg.3x to use_default_colors.3ncurses in
+	  man_db.renames, since Debian is not concerned with 14-character
+	  filename limitation (Debian bug report by Josip Rodin
+	  <joy@cibalia.gkvk.hr>).
+	+ corrected scoansi terminfo entry by testing with scoterm and console.
+	+ revert change from 990614 to terminal_interface-curses-forms.ads.m4,
+	  since this does not work for gnat 3.10p
+	+ modify tclock example to be resizable (if ncurses' sigwinch handler
+	  is used), and in color.
+	+ use $(CC) rather than 'gcc' in MK_SHARED_LIB symbols, used for Linux
+	  shared library rules.
+
+990925	pre-release
+	+ add newer NetBSD console terminfo entries
+	+ add amiga-8bit terminfo entry (from Henning 'Faroul' Peters
+	  <Faroul@beyond.kn-bremen.de>)
+	+ remove -lcurses -ltermcap from configure script's check for the gpm
+	  library, since they are not really necessary (a properly configured
+	  gpm library has no dependency on any curses library), and if the
+	  curses library is not installed, this would cause the test to fail.
+	+ modify tic's -C option so that terminfo "use=" clauses are translated
+	  to "tc=" clauses even when running it as captoinfo.
+	+ modify CF_STDCPP_LIBRARY configure macro to perform its check only
+	  for GNU C++, since that library conflicts with SGI's libC on IRIX-6.2
+	+ modify CF_SHARED_OPTS configure macro to support build on NetBSD with
+	  ELF libraries (patch by Bernd Ernesti <bernd@arresum.inka.de>).
+	+ correct a problem in libpanel, where the _nc_top_panel variable was
+	  not set properly when bottom_panel() is called to hide a panel which
+	  is the only one on the stack (report/analysis by Michael Andres
+	  <ma@suse.de>, patch by Juergen Pfeifer).
+
+990918	pre-release
+	+ add acsc string to HP 70092 terminfo entry (patch by Joerg Wunsch
+	  <j@interface-business.de>).
+	+ add top-level uninstall.data and uninstall.man makefile rules.
+	+ correct logic of CF_LINK_FUNCS configure script, from BeOS changes so
+	  that hard-links work on Unix again.
+	+ change default value of cf_cv_builtin_bool to 1 (suggested by
+	  Jeremy Buhler), making it less likely that a conflicting declaration
+	  of bool will be seen when compiling with C++.
+
+990911	pre-release
+	+ improved configure checks for builtin.h
+	+ minor changes to C++ binding (remove static initializations, and make
+	  configure-test for parameter initializations) for features not
+	  allowed by vendor's C++ compilers (reported by Martin Mokrejs, this
+	  applies to SGI, though I found SCO has the same characteristics).
+	+ corrected quoting of ETIP_xxx definitions which support old versions
+	  of g++, e.g., those using -lg++
+	+ remove 'L' code from safe_sprintf.c, since 'long double' is not
+	  widely portable.  safe_sprintf.c is experimental, however, and
+	  exists mainly as a fallback for systems without snprintf (reported
+	  by Martin Mokrejs <mmokrejs@natur.cuni.cz>, for IRIX 6.2)
+	+ modify definition of _nc_tinfo_fkeys in broken-linker configuration
+	  so that it is not unnecessarily made extern (Jeffrey C Honig).
+
+990904	pre-release
+	+ move definition for builtin.h in configure tests to specific check
+	  for libg++, since qt uses the same filename incompatibly.
+	+ correct logic of lib_termcap.c tgetstr function, which did not copy
+	  the result to the buffer parameter.  Testing shows Solaris does
+	  update this, though of course tgetent's buffer is untouched (reported
+	  in Peter Edwards <peter.edwards@ireland.com> in
+	  mpc.lists.freebsd.current newsgroup.
+	+ corrected beterm terminfo entry, which lists some capabilities which
+	  are not actually provided by the BeOS Terminal.
+	+ add special logic to replace select() calls on BeOS, whose select()
+	  function works only for sockets.
+	+ correct missing escape in mkterm.h.awk.in, which caused part
+	  of the copyright noticed to be omitted (reported by Peter
+	  Wemm <peter@netplex.com.au>).
+	> several small changes to make the c++ binding and demo work on OS/2
+	  EMX (related to a clean reinstall of EMX):
+	+ correct library-prefix for c++ binding; none is needed.
+	+ add $x suffix to make_hash and make_keys so 'make distclean' works.
+	+ correct missing $x suffix for tack, c++ demo executables.
+	+ split CF_CXX_LIBRARY into CF_GPP_LIBRARY (for -lg++) and
+	  CF_STDCPP_LIBRARY (for -lstdc++)
+
+990828	pre-release
+	+ add cygwin terminfo entry -TD
+	+ modify CF_PROG_EXT configure macro to set .exe extension for cygwin.
+	+ add configure option --without-cxx-binding, modifying the existing
+	  --without-cxx option to check only for the C++ compiler
+	  characteristics.  Whether or not the C++ binding is needed, the
+	  configure script checks for the size/type of bool, to make ncurses
+	  match.  Otherwise C++ applications cannot use ncurses.
+
+990821	pre-release
+	+ updated configure macros CF_MAKEFLAGS, CF_CHECK_ERRNO
+	+ minor corrections to beterm terminfo entry.
+	+ modify lib_setup.c to reject values of $TERM which have a '/' in
+	  them.
+	+ add ifdef's to guard against CS5, CS6, CS7, CS8 being zero, as more
+	  than one is on BeOS.  That would break a switch statement.
+	+ add configure macro CF_LINK_FUNCS to detect and work around BeOS's
+	  nonfunctional link().
+	+ improved configure macros CF_BOOL_DECL and CF_BOOL_SIZE to detect
+	  BeOS's bool, which is declared as an unsigned char.
+
+990814	pre-release
+	+ add ms-vt100 terminfo entry -TD
+	+ minor fixes for misc/emx.src, based on testing with tack.
+	+ minor fix for test/ncurses.c, test 'a', in case ncv is not set.
+
+990731	pre-release
+	+ minor correction for 'screen' terminfo entry.
+	+ clarify description of errret values for setupterm in manpage.
+	+ modify tput to allow it to emit capabilities for hardcopy terminals
+	  (patch by Goran Uddeborg <goeran@uddeborg.pp.se>).
+	+ modify the 'o' (panel) test in ncurses.c to show the panels in color
+	  or at least in bold, to test Juergen's change to wrefresh().
+	> patches by Juergen Pfeifer:
+	+ Fixes a problem using wbkgdset() with panels.  It has actually
+	  nothing to with panels but is a problem in the implementation of
+	  wrefresh().  Whenever a window changes its background attribute to
+	  something different than newscr's background attribute, the whole
+	  window is touched to force a copy to newscr.  This is an unwanted
+	  side-effect of wrefresh() and it is actually not necessary.  A
+	  changed background attribute affects only further outputs of
+	  background it doesn't mean anything to the current content of the
+	  window.  So there is no need to force a copy.  (reported by Frank
+	  Heckenbach <frank@g-n-u.de>).
+	+ an upward compatible enhancement of the NCursesPad class in the C++
+	  binding.  It allows one to add a "viewport" window to a pad and then
+	  to use panning to view the pad through the viewport window.
+
+990724	pre-release
+	+ suppress a call to def_prog_mode() in the SIGTSTP handler if the
+	  signal was received while not in curses mode, e.g., endwin() was
+	  called in preparation for spawning a shell command (reported by Frank
+	  Heckenbach <frank@g-n-u.de>)
+	+ corrected/enhanced xterm-r5, xterm+sl, xterm+sl-twm terminfo entries.
+	+ change test for xterm mouse capability:  it now checks only if the
+	  user's $DISPLAY variable is set in conjunction with the kmous
+	  capability being present in the terminfo.  Before, it checked if any
+	  of "xterm", "rxvt" or "kterm" were substrings of the terminal name.
+	  However, some emulators which are incompatible with xterm in other
+	  ways do support the xterm mouse capability.
+	+ reviewed and made minor changes in ncurses to quiet g++ warnings
+	  about shadowed or uninitialized variables.  g++ incorrectly warns
+	  about uninitialized variables because it does not take into account
+	  short-circuit expression evaluation.
+	+ change ncurses 'b' test to start in color pair 0 and to show in the
+	  right margin those attributes which are suppressed by no_color_video,
+	  i.e., "(NCV)".
+	+ modify ifdef's in curses.h so that __attribute__ is not redefined
+	  when compiling with g++, but instead disabled the macros derived for
+	  __attribute__ since g++ does not consistently recognize the same
+	  keywords as gcc (reported by Stephan K Zitz <zitz@erf.net>).
+	+ update dependencies for term.h in ncurses/modules (reported by
+	  Ilya Zakharevich).
+
+990710	pre-release
+	+ modify the form demo in ncurses.c to illustrate how to manipulate the
+	  field appearance, e.g, for highlighting or translating the field
+	  contents.
+	+ correct logic in write_entry from split-out of home_terminfo in
+	  980919, which prevented update of $HOME/.terminfo (reported by Philip
+	  Spencer <pspencer@fields.utoronto.ca>).
+
+990703	pre-release
+	+ modify linux terminfo description to make use of kernel 2.2.x mods
+	  that support cursor style, e.g., to implement cvvis (patch by Frank
+	  Heckenbach <frank@g-n-u.de>)
+	+ add special-case in setupterm to retain previously-saved terminal
+	  settings in cur_term, which happens when curses and termcap calls are
+	  mixed (from report by Bjorn Helgaas <helgaas@dhc.net>).
+	+ suppress initialization of key-tries in _nc_keypad() if we are only
+	  disabling keypad mode, e.g., in endwin() called when keypad() was
+	  not.
+	+ modify the Ada95 makefile to ensure that always the Ada files from
+	  the development tree are used for building and not the eventually
+	  installed ones (patch by Juergen Pfeifer).
+
+990626	pre-release
+	+ use TTY definition in tack/sysdep.c rather than struct termios
+	  (reported by Philippe De Muyter).
+	+ add a fallback for strstr, used in lib_mvcur.c and tack/edit.c,
+	  not present on sysV68 (reported by Philippe De Muyter).
+	+ correct definition in comp_hash.c to build with configure
+	  --with-rcs-ids option.
+
+990619	pre-release
+	+ modified ifdef's for sigaction and sigvec to ensure we do not try to
+	  handle SIGTSTP if neither is available (from report by Philippe De
+	  Muyter).
+	> patch by Philippe De Muyter:
+	+ in tic.c, use `unlink' if `remove' is not available.
+	+ use only `unsigned' as fallback value for `speed_t'.  Some files used
+	  `short' instead.
+
+990616	pre-release
+	+ fix some compiler warnings in tack.
+	+ add a check for predefined bool type in CC, based on report that
+	  BeOS predefines a bool type.
+	+ correct logic for infocmp -e option, i.e., the configure
+	  --with-fallbacks option, which I'd not updated when implementing
+	  extended names (cf:  990301).  The new implementation adds a "-E"
+	  option to infocmp -TD
+	> patch by Juergen Pfeifer:
+	+ introduce the private type Curses_Bool in the Ada95 binding
+	  implementation.  This is to clearly represent the use of "bool" also
+	  in the binding.  It should have no effect on the generated code.
+	+ improve the man page for field_buffer() to tell the people, that the
+	  whole buffer including leading/trailing spaces is returned.  This is
+	  a common source of confusion, so it's better to document it clearly.
+
+990614	pre-release
+	> patch by Juergen Pfeifer:
+	+ use pragma PreElaborate in several places.
+	+ change a few System.Address uses to more specific types.
+	+ change interface version-number to 1.0
+	+ regenerate Ada95 HTML files.
+
+990612	pre-release
+	+ modify lib_endwin.c to avoid calling reset_shell_mode(), return ERR
+	  if it appears that curses was never initialized, e.g., by initscr().
+	  For instance, this guards against setting the terminal modes to
+	  strange values if endwin() is called after setupterm().  In the same
+	  context, Solaris curses will dump core.
+	+ modify logic that avoids a conflict in lib_vidattr.c between sgr0 and
+	  equivalent values in rmso or rmul by ensuring we do not modify the
+	  data which would be returned by the terminfo or termcap interfaces
+	  (reported by Brad Pepers <brad@linuxcanada.com>, cf:  960706).
+	+ add a null-pointer check for SP in lib_vidattr.c to logic that checks
+	  for magic cookies.
+	+ improve fallback declaration of 'bool' when the --without-cxx option
+	  is given, by using a 'char' on i386 and related hosts (prompted by
+	  discussion with Alexander V Lukyanov).
+
+990605	pre-release
+	+ include time.h in lib_napms.c if nanosleep is used (patch by
+	  R Lindsay Todd <toddr@rpi.edu>).
+	+ add an "#undef bool" to curses.h, in case someone tries to define it,
+	  e.g., perl.
+	+ add check to tparm to guard against divide by zero (reported by Aaron
+	  Campbell <aaron@ug.cs.dal.ca>).
+
+990516	pre-release
+	+ minor fix to build tack on CLIX (mismatched const).
+	> patch by Juergen Pfeifer:
+	+ change Juergen's old email address with new one in the files where it
+	  is referenced.  The Ada95 HTML pages are regenerated.
+	+ update MANIFEST to list the tack files.
+
+990509	pre-release
+	+ minor fixes to make 'tack' build/link on NeXT (reported by Francisco
+	  A. Tomei Torres).
+
+990417	pre-release
+	+ add 'tack' program (which is GPL'd), updating it to work with the
+	  modified TERMTYPE struct and making a fix to support setaf/setab
+	  capabilities.  Note that the tack program is not part of the
+	  ncurses libraries, but an application which can be distributed with
+	  ncurses.  The configure script will ignore the directory if it is
+	  omitted, however.
+	+ modify gpm mouse support so that buttons 2 and 3 are used for
+	  select/paste only when shift key is pressed, making them available
+	  for use by an application (patch by Klaus Weide).
+	+ add complete list of function keys to scoansi terminfo entry - TD
+
+990410	pre-release
+	+ add a simple test program cardfile.c to illustrate how to read form
+	  fields, and showing forms within panels.
+	+ change shared-library versioning for the Hurd to be like Linux rather
+	  than *BSD (patch by Mark Kettenis <kettenis@wins.uva.nl>).
+	+ add linux-lat terminfo entry.
+	+ back-out _nc_access check in read_termcap.c (both incorrect and
+	  unnecessary, except to guard against a small window where the file's
+	  ownership may change).
+
+990403	pre-release
+	+ remove conflicting _nc_free_termtype() function from test module
+	  lib_freeall.c
+	+ use _nc_access check in read_termcap.c for termpaths[] array (noted
+	  by Jeremy Buhler, indicating that Alan Cox made a similar patch).
+	> patch by Juergen Pfeifer:
+	+ modify menu creation to not inherit status flag from the default menu
+	  which says that the associated marker string has been allocated and
+	  should be freed (bug reported by Marek Paliwoda"
+	  <paliwoda@kki.net.pl>)
+
+990327	pre-release (alpha.gnu.org:/gnu/ncurses-5.0-beta1.tar.gz)
+	+ minor fixes to xterm-xfree86 terminfo entry - TD.
+	+ split up an expression in configure script check for ldconfig to
+	  workaround limitation of BSD/OS sh (reported by Jeff Haas
+	  <jmh@mail.msen.com>).
+	+ correct a typo in man/form_hook.3x (Todd C Miller).
+
+990318	pre-release
+	+ parenthesize and undef 'index' symbol in c++ binding and demo, to
+	  accommodate its definition on NeXT (reported by Francisco A. Tomei
+	  Torres).
+	+ add sigismember() to base/sigaction.c compatibility to link on NeXT
+	  (reported by Francisco A. Tomei Torres).
+	+ further refinements to inequality in hashmap.c to cover a case with
+	  ^U in nvi (patch by Alexander V Lukyanov).
+
+990316	pre-release
+	+ add fallback definition for getcwd, to link on NeXT.
+	+ add a copy of cur_term to tic.c to make it link properly on NeXT
+	  (reported by Francisco A. Tomei Torres).
+	+ change inequality in hashmap.c which checks the distance traveled by
+	  a chunk so that ^D command in nvi (scrolls 1/2 screen) will use
+	  scrolling logic (patch by Alexander V Lukyanov, reported by Jeffrey
+	  C Honig).
+
+990314	pre-release
+	+ modify lib_color.c to handle a special case where the curscr
+	  attributes have been made obsolete (patch by Alexander V Lukyanov).
+	+ update BSD/OS console terminfo entries to use klone+sgr and
+	  klone+color (patch by Jeffrey C Honig).
+	+ update glibc addon configure script for extended capabilities.
+	+ correct a couple of warnings in the --enable-const configuration.
+	+ make comp_hash build properly with _nc_strdup(), on NeXT (reported by
+	  Francisco A. Tomei Torres <francisco.tomei@cwix.com>).
+
+990313	pre-release
+	+ correct typos in linux-c initc string - TD
+	+ add 'crt' terminfo entry, update xterm-xfree86 entry - TD
+	+ remove a spurious argument to tparm() in lib_sklrefr.c (patch by
+	  Alexander V Lukyanov).
+
+990307	pre-release
+	+ back-out change to wgetch because it causes a problem with ^Z
+	  handling in lynx (reported by Kim DeVaughn).
+
+990306	pre-release
+	+ add -G option to tic and infocmp, to reverse the "-g" option.
+	+ recode functions in name_match.c to avoid use of strncpy, which
+	  caused a 4-fold slowdown in tic (cf: 980530).
+	+ correct a few warnings about sign-extension in recent changes.
+	> patch by Juergen Pfeifer:
+	+ fixes suggested by Jeff Bradbury <jibradbury@lucent.com>:
+	  + improved parameter checking in new_fieldtype().
+	  + fixed a typo in wgetch() timeout handling.
+	  + allow slk_init() to be called per newterm call.  The internal SLK
+	    state is stored in the SCREEN struct after every newterm() and then
+	    reset for the next newterm.
+	  + fix the problem that a slk_refresh() refreshes stdscr if the
+	    terminal has true SLKs.
+	+ update HTML documentation for Ada binding.

+	+ remove 'bool' casts from definitions of TRUE/FALSE so that statements
+	  such as "#if TRUE" work.  This was originally done to allow for a C++
+	  compiler which would warn of implicit conversions between enum and
+	  int, but is not needed for g++ (reported by Kim DeVaughn).
+	+ add use_extended_names() function to allow applications to suppress
+	  read of the extended capabilities.
+	+ add configure option --enable-tcap-names to support logic which
+	  allows ncurses' tic to define new (i.e., extended) terminal
+	  capabilities.  This is activated by the tic -x switch.  The infocmp
+	  program automatically shows or compares extended capabilities.
+	  Note:  This changes the Strings and similar arrays in the TERMTYPE
+	  struct so that applications which manipulate it must be recompiled.
+	+ use macros typeMalloc, typeCalloc and typeRealloc consistently
+	  throughout ncurses library.
+	+ add _nc_strdup() to doalloc.c.
+	+ modify define_key() to allow multiple strings to be bound to the
+	  same keycode.
+	+ correct logic error in _nc_remove_string, from 990220.
+	> patch for Ada95 binding (Juergen Pfeifer):
+	+ regenerate some of the html documentation
+	+ minor cleanup in terminal_interface-curses.adb
+
+990220	pre-release
+	+ resolve ambiguity of kend/kll/kslt and khome/kfnd/kich1 strings in
+	  xterm and ncsa terminfo entries by removing the unneeded ones.  Note
+	  that some entries will return kend & khome versus kslt and kfnd, for
+	  PC-style keyboards versus strict vt220 compatibility - TD
+	+ add function keybound(), which returns the definition associated with
+	  a given keycode.
+	+ modify define_key() to undefine the given string when no keycode is
+	  given.
+	+ modify keyok() so it works properly if there is more than one string
+	  defined for a keycode.
+	+ add check to tic to warn about terminfo descriptions that contain
+	  more than one key assigned to the same string.  This is shown only if
+	  the verbose (-v) option is given.  Moved related logic (tic -v) from
+	  comp_parse.c into the tic program.
+	+ add/use _nc_trace_tries() to show the function keys that will be
+	  recognized.
+	+ rename init_acs to _nc_init_acs (request by Alexander V Lukyanov).
+	> patch for Ada95 binding (Juergen Pfeifer):
+	+ remove all the *_adabind.c from ncurses, menu and form projects.
+	  Those little helper routines have all been implemented in Ada and are
+	  no longer required.
+	+ The option handling routines in menu and form have been made more
+	  save.  They now make sure that the unused bits in options are always
+	  zero.
+	+ modify configuration scripts to
+	  + use gnatmake as default compiler name.  This is a safer choice than
+	    gcc, because some GNAT implementations use other names for the
+	    compilerdriver to avoid conflicts.
+	  + use new default installation locations for the Ada files according
+	    to the proposed GNU Ada filesystem standard (for Linux).
+	+ simplify the Makefiles for the Ada binding
+	+ rename ada_include directory to src.
+
+990213
+	+ enable sigwinch handler by default.
+	+ disable logic that allows setbuf to be turned off/on, because some
+	  implementations will overrun the buffer after it has been disabled
+	  once.
+
+990206
+	+ suppress sc/rc capabilities from terminal description if they appear
+	  in smcup/rmcup.  This affects only scrolling optimization, to fix a
+	  problem reported by several people with xterm's alternate screen,
+	  though the problem is more general.
+	> patch for Ada95 binding (Juergen Pfeifer):
+	+ removed all pragma Preelaborate() stuff, because the just released
+	  gnat-3.11p complains on some constructs.
+	+ fixed some upper/lower case notations because gnat-3.11p found
+	  inconsistent use.
+	+ used a new method to generate the HTML documentation of the Ada95
+	  binding.  This invalidates nearly the whole ./Ada95/html subtree.
+	  Nearly all current files in this subtree are removed
+
+990130
+	+ cache last result from _nc_baudrate, for performance (suggested by
+	  Alexander V Lukyanov).
+	+ modify ClrUpdate() function to workaround a problem in nvi, which
+	  uses redrawwin in SIGTSTP handling.  Jeffrey C Honig reported that
+	  ncurses repainted the screen with nulls before resuming normal
+	  operation (patch by Alexander V Lukyanov).
+	+ generalize is_xterm() function a little by letting xterm/rxvt/kterm
+	  be any substring rather than the prefix.
+	+ modify lib_data.c to initialize SP.  Some linkers, e.g., IBM's, will
+	  not link a module if the only symbols exported from the module are
+	  uninitialized ones (patch by Ilya Zakharevich).  Ilya says that he
+	  has seen messages claiming this behavior conforms to the standard.)
+	+ move call on _nc_signal_handler past _nc_initscr, to avoid a small
+	  window where Nttyb hasn't yet been filled (reported by Klaus Weide).
+	+ modify lib_tstp.c to block SIGTTOU when handling SIGTSTP, fixes a
+	  problem where ncurses applications which were run via a shell script
+	  would hang when given a ^Z.  Also, check if the terminal's process
+	  group is consistent, i.e., a shell has not taken ownership of it,
+	  before deciding to save the current terminal settings in the SIGTSTP
+	  handler (patch by Klaus Weide).
+	+ correct spelling of ACS_ names in curs_border.3x (reported by Bob van
+	  der Poel <bvdpoel@kootenay.com>).
+	+ correct a couple of typos in the macros supporting the configure
+	  --with-shlib-version option.
+
+990123
+	+ modify fty_regex.c to compile on HAVE_REGEXPR_H_FUNCS machine (patch
+	  by Kimio Ishii <ishii@csl.sony.co.jp>).
+	+ rename BSDI console terminfo entries:  bsdos to bsdos-pc-nobold, and
+	  bsdos-bold to bsdos-pc (patch by Jeffrey C Honig).
+	+ modify tput to accept termcap names as an alternative to terminfo
+	  names (patch by Jeffrey C Honig).
+	+ correct a typo in term.7 (Todd C Miller).
+	+ add configure --with-shlib-version option to allow installing shared
+	  libraries named according to release or ABI versions.  This
+	  parameterizes some existing logic in the configure script, and is
+	  intended for compatibility upgrades on Digital Unix, which used
+	  versioned libraries in ncurses 4.2, but no longer does (cf:  980425).
+	+ resync configure script against autoconf 2.13 + patches
+	+ minor improvements for teraterm terminfo entry based on the program's
+	  source distribution.
+
+990116
+	+ change default for configure --enable-big-core to assume machines do
+	  have enough memory to resolve terminfo.src in-memory.
+	+ correct name of ncurses library in TEST_ARGS when configuring with
+	  debug library.
+	+ minor fixes to compile ncurses library with broken-linker with g++.
+	+ add --enable-broken-linker configure option, default to environment
+	  variable $BROKEN_LINKER (request by Jeffrey C Honig).
+	+ change key_names[] array to static since it is not part of the curses
+	  interface (reported by Jeffrey C Honig <jch@bsdi.com>).
+
+990110
+	+ add Tera Term terminfo entry - TD
+
+990109
+	+ reviewed/corrected macros in curses.h as per XSI document.
+	+ provide support for termcap PC variable by copying it from terminfo
+	  data and using it as the padding character in tputs (reported by
+	  Alexander V Lukyanov).
+	+ corrected iris-ansi and iris-ansi-ap terminfo entries for kent and
+	  kf9-kf12 capabilities, as well as adding kcbt.
+	+ document the mouse handling mechanism in menu_driver and make a small
+	  change in menu_driver's return codes to provide more consistency
+	  (patch by Juergen Pfeifer).
+	+ add fallback definition for NCURSES_CONST to termcap.h.in (reported
+	  by Uchiyama Yasushi <uch@nop.or.jp>).
+	+ move lib_restart.c to ncurses/base, since it uses curses functions
+	  directly, and therefore cannot be used in libtinfo.so
+	+ rename micro_char_size to micro_col_size, adding #define to retain
+	  old name.
+	+ add set_a_attributes and set_pglen_inch to terminfo structure, as per
+	  XSI and Solaris 2.5.
+	+ minor makefile files to build ncurses test_progs
+	+ update html files in misc directory to reflect changes since 4.2
+
+990102
+	+ disable scroll hints when hashmap is enabled (patch by Alexander
+	  V Lukyanov).
+	+ move logic for tic's verify of -e option versus -I and -C so that the
+	  terminfo data is not processed if we cannot handle -e (reported by
+	  Steven Schwartz <steves@unitrends.com>.
+	+ add test-driver traces to terminfo and termcap functions.
+	+ provide support for termcap ospeed variable by copying it from the
+	  internal cur_term member, and using ospeed as the baudrate reference
+	  for the delay_output and tputs functions.  If an application does not
+	  set ospeed, the library behaves as before, except that _nc_timed_wait
+	  is no longer used, or needed, since ospeed always has a value.  But
+	  the application can modify ospeed to adjust the output of padding
+	  characters (prompted by a bug report for screen 3.7.6 and email from
+	  Michael Schroeder <Michael.Schroeder@informatik.uni-erlangen.de>).
+	+ removed some unused ifdef's as part of Alexander's restructuring.
+	+ reviewed/updated curses.h, term.h against X/Open Curses Issue 4
+	  Version 2.  This includes making some parameters NCURSES_CONST
+	  rather than const, e.g., in termcap.h.
+	+ change linux terminfo entry to use ncv#2, since underline does not
+	  work with color
+
+981226
+	+ miscellaneous corrections for curses.h to match XSI.
+	+ change --enable-no-padding configure option to be normally enabled.
+	+ add section to ncurses manpage for environment variables.
+	+ investigated Debian bug report that pertains to screen 3.7.4/3.7.6
+	  changes, found no sign of problems on Linux (or on SunOS, Solaris)
+	  running screen built with ncurses.
+	+ check if tmp_fp is opened in tic.c before closing it (patch by Pavel
+	  Roskin <pavel_roskin@geocities.com>).
+	+ correct several font specification typos in man-pages.
+
+981220
+	+ correct default value for BUILD_CC (reported by Larry Virden).
+
+981219
+	+ modify _nc_set_writedir() to set a flag in _nc_tic_dir() to prevent
+	  it from changing the terminfo directory after chdir'ing to it.
+	  Otherwise, a relative path in $TERMINFO would confuse tic (prompted
+	  by a Debian bug report).
+	+ correct/update ncsa terminfo entry (report by Larry Virden).
+	+ update xterm-xfree86 terminfo to current (patch 90), smcur/rmcur
+	  changes
+	+ add Mathew Vernon's mach console entries to terminfo.src
+	+ more changes, moving functions, as part of Alexander's restructuring.
+	+ modify configure script for GNU/Hurd share-library support, introduce
+	  BUILD_CC variable for cross compiling (patch by Uchiyama Yasushi
+	  <uch@nop.or.jp>)
+
+981212
+	+ add environment variable NCURSES_NO_SETBUF to allow disabling the
+	  setbuf feature, for testing purposes.
+	+ correct ifdef's for termcap.h versus term.h that suppress redundant
+	  declarations of prototypes (reported by H.J.Lu).
+	+ modify Makefile.os2 to add linker flags which allow multiple copies
+	  of an application to coexist (reported by Ilya Zakharevich).
+	+ update Makefile.glibc and associated configure script so that ncurses
+	  builds as a glibc add-on with the new directory configuration
+	  (reported by H.J.Lu).
+
+981205
+	+ modify gen_reps() function in gen.c to work properly on SunOS
+	  (sparc), which is a left-to-right architecture.
+	+ modify relative_move and tputs to avoid an interaction with the
+	  BSD-style padding.  The relative_move function could produce a string
+	  to replace on the screen which began with a numeric character, which
+	  was then interpreted by tputs as padding.  Now relative_move will not
+	  generate a string with a leading digit in that case (overwrite).
+	  Also, tputs will only interpret padding if the string begins with a
+	  digit; as coded it permitted a string to begin with a decimal point
+	  or asterisk (reported by Larry Virden).
+	> patches by Juergen Pfeifer:
+	+ fix a typo in m_driver.c mouse handling and improves the error
+	  handling.
+	+ fix broken mouse handling in the Ada95 binding
+	+ make the Ada95 sample application menus work with the new menu mouse
+	  support
+	+ improve the mouse handling introduced by Ilya; it now handles menus
+	  with spacing.
+	+ repair a minor bug in the menu_driver code discovered during this
+	  rework.
+	+ add new function wmouse_trafo() to hide implementation details of
+	  _yoffset member of WINDOW struct needed for mouse coordinate
+	  transformation.
+
+981128
+	+ modify Ada95/gen/gen.c to avoid using return-value of sprintf, since
+	  some older implementations (e.g., SunOS 4.x) return the buffer
+	  address rather than its length.
+	> patch by Rick Ohnemus:
+	+ modify demo.cc to get it to compile with newer versions of egcs.
+	+ trim a space that appears at the end of the table preprocessor lines
+	  ('\" t).  This space prevents some versions of man from displaying
+	  the pages - changed to remove all trailing whitespace (TD)
+	+ finally, 'make clean' does not remove panel objects.
+	> patches by Ilya Zakharevich:
+	+ allow remapping of OS/2 mouse buttons using environment variable
+	  MOUSE_BUTTONS_123 with the default value 132.
+	+ add mouse support to ncurses menus.
+
+981121
+	+ modify misc/makedef.cmd to report old-style .def file symbols, and to
+	  generate the .def files sorted by increasing names rather than the
+	  reverse.
+	+ add misc/*.ref which are J.J.G.Ripoll's dll definition files (renamed
+	  from misc/*.old), and updated based on the entrypoint coding he used
+	  for an older version of ncurses.
+	+ add README.emx, to document how to build on OS/2 EMX.
+	+ updates for config.guess, config.sub from Lynx
+	> patches by Ilya Zakharevich:
+	+ minor fixes for mouse handling mode:
+	  a) Do not initialize mouse if the request is to have no mouse;
+	  b) Allow switching of OS/2 VIO mouse on and off.
+	+ modify Makefile.os2 to support alternative means of generating
+	  configure script, by translating Unix script with Perl.
+	> patches by Juergen Pfeifer:
+	+ Updates MANIFEST to reflect changes in source structure
+	+ Eliminates a problem introduced with my last patch for the C++
+	  binding in the panels code.  It removes the update() call done in the
+	  panel destructor.
+	+ Changes in the Ada95 binding to better support systems where
+	  sizeof(chtype)!=sizeof(int) (e.g.  DEC Alpha).
+
+981114
+	+ modify install-script for manpages to skip over .orig and .rej files
+	  (request by Larry Virden).
+	> patches/discussion by Alexander V Lukyanov:
+	+ move base-library sources into ncurses/base and tty (serial terminal)
+	  sources into ncurses/tty, as part of Alexander V Lukyanov's proposed
+	  changes to ncurses library.
+	+ copy _tracemouse() into ncurses.c so that lib_tracemse.c need not
+	  be linked into the normal ncurses library.
+	+ move macro winch to a function, to hide details of struct ldat
+	> patches by Juergen Pfeifer:
+	+ fix a potential compile problem in cursesw.cc
+	+ some Ada95 cosmetics
+	+ fix a gen.c problem when compiling on 64-Bit machines
+	+ fix Ada95/gen/Makefile.in "-L" linker switch
+	+ modify Ada95 makefiles to use the INSTALL_PREFIX setting.
+
+981107
+	+ ifdef'd out lib_freeall.c when not configured.
+	+ rename _tracebits() to _nc_tracebits().
+	+ move terminfo-library sources into ncurses/tinfo, and trace-support
+	  functions into ncurses/trace as part of Alexander V Lukyanov's
+	  proposed changes to ncurses library.
+	+ modify generated term.h to always specify its own definitions for
+	  HAVE_TERMIOS_H, etc., to guard against inclusion by programs with
+	  broken configure scripts.
+
+981031
+	+ modify terminfo parsing to accept octal and hexadecimal constants,
+	  like Solaris.
+	+ remove an autoconf 2.10 artifact from the configure script's check
+	  for "-g" compiler options.  (Though harmless, this confused someone
+	  at Debian, who recently issued a patch that results in the opposite
+	  effect).
+	+ add configure option --with-ada-compiler to accommodate installations
+	  that do not use gcc as the driver for GNAT (patch by Juergen
+	  Pfeifer).
+
+981017
+	+ ensure ./man exists in configure script, needed when configuring
+	  with --srcdir option.
+	+ modify infocmp "-r" option to remove limit on formatted termcap
+	  output, which makes it more like Solaris' version.
+	+ modify captoinfo to treat no-argument case more like Solaris'
+	  version, which uses the contents of $TERMCAP as the entry to format.
+	+ modify mk-2nd.awk to handle subdirectories, e.g., ncurses/tty
+	  (patch by Alexander V Lukyanov).
+
+981010
+	+ modify --with-terminfo-dirs option so that the default value is the
+	  ${datadir} value, unless $TERMINFO_DIRS is already set.  This gets
+	  rid of a hardcoded list of candidate directories in the configure
+	  script.
+	+ add some error-checking to _nc_read_file_entry() to ensure that
+	  strings are properly terminated (Todd C Miller).
+	+ rename manpage file curs_scr_dmp.3x to curs_scr_dump.3x, to
+	  correspond with contents (reported by Neil Zanella
+	  <nzanella@cs.mun.ca>).
+	+ remove redundant configure check for C++ which did not work when $CXX
+	  was specified with a full pathname (reported by Andreas Jaeger).
+	+ corrected bcopy/memmove check; the macro was not standalone.
+
+981003
+	+ remove unnecessary portion of OS/2 EMX mouse change from
+	  check_pending() (reported by Alexander V Lukyanov).
+
+980926
+	+ implement mouse support for OS/2 EMX (adapted from patch against
+	  4.2(?) by Ilya Zakharevich).
+	+ add configure-check for bcopy/memmove, for 980919 changes to hashmap.
+	+ merge Data General terminfo from Hasufin <hasufin@vidnet.net> - TD
+	+ merge AIX 3.2.5 terminfo descriptions for IBM terminals, replaces
+	  some older entries - TD
+	+ modify tic to compile into %'char' form in preference to %{number},
+	  since that is a little more efficient.
+	+ minor correction to infocmp to avoid displaying "difference" between
+	  two capabilities that are rendered in equivalent forms.
+	+ add "-g" option to tic/infocmp to force character constants to be
+	  displayed in quoted form.  Otherwise their decimal values are shown.
+	+ modify setupterm so that cancelled strings are treated the same as
+	  absent strings, cancelled and absent booleans false (does not affect
+	  tic, infocmp).
+	+ modify tic, infocmp to discard redundant i3, r3 strings when output
+	  to termcap format.
+	> patch by Alexander V Lukyanov:
+	+ improve performance of tparm, now it takes 19% instead of 25% when
+	  profiling worm.
+	+ rename maxlen/minlen to prec/width for better readability.
+	+ use format string for printing strings.
+	+ use len argument correctly in save_text, and pass it to save_number.
+
+980919
+	+ make test_progs compile (but hashmap does not function).
+	+ correct NC_BUFFERED macro, used in lib_mvcur test-driver, modify
+	  associated logic to avoid freeing the SP->_setbuf data.
+	+ add modules home_terminfo and getenv_num to libtinfo.
+	+ move write_entry to libtinfo, to work with termcap caching.
+	+ minor fixes to blue.c to build with atac.
+	+ remove softscroll.c module; no longer needed for testing.
+	> patches by Todd C Miller:
+	+ use strtol(3) instead of atoi(3) when parsing env variables so we can
+	  detect a bogus (non-numeric) value.
+	+ check for terminal names > MAX_NAME_SIZE in a few more places when
+	  dealing with env variables again.
+	+ fix a MAX_NAME_SIZE that should be MAX_NAME_SIZE+1
+	+ use sizeof instead of strlen(3) on PRIVATE_INFO since it is a fixed
+	  string #define (compile time vs runtime).
+	+ when setting errno to ENOMEM, set it right before the return, not
+	  before code that could, possibly, set errno to a different value.
+	> patches by Alexander V Lukyanov:
+	+ use default background in update_cost_from_blank()
+	+ disable scroll-hints when hashmap is configured.
+	+ improve integration of hashmap scrolling code, by adding oldhash and
+	  newhash data to SP struct.
+	+ invoke del_curterm from delscreen.
+	+ modify del_curterm to set cur_term to null if it matches the
+	  function's parameter which is deleted.
+	+ modify lib_doupdate to prefer parm_ich to the enter_insert_mode and
+	  exit_insert_mode combination, adjusting InsCharCost to check
+	  enter_insert_mode, exit_insert_mode and insert_padding.  Add
+	  insert_padding in insert mode after each char.  This adds new costs
+	  to the SP struct.
+
+980912
+	+ modify test-driver in lib_mvcur.s to use _nc_setbuffer, for
+	  consistent treatment.
+	+ modify ncurses to restore output to unbuffered on endwin, and resume
+	  buffering in refresh (see lib_set_term.c and NC_BUFFERED macro).
+	+ corrected HTML version numbers (according to the W3C validator, they
+	  never were HTML 2.0-compliant, but are acceptable 3.0).
+
+980905
+	+ modify MKterminfo.sh to generate terminfo.5 with tables sorted by
+	  capability name, as in SVr4.
+	+ modified term.h, termcap.h headers to avoid redundant declarations.
+	+ change 'u_int' type in tset.c to unsigned, making this compile on
+	  Sequent PRX 4.1 (reported by Michael Sterrett <msterret@coat.com>).
+
+980829
+	+ corrections to mailing addresses, and moving the magic line that
+	  causes the man program to invoke tbl to the first line of each
+	  manpage (patch by Rick Ohnemus <rick@ecompcon.com>).
+	+ add Makefile.os2 and supporting scripts to generate dll's on OS/2 EMX
+	  (from J.J.G.Ripoll, with further integration by TD).
+	+ correct a typo in icl6404 terminfo entry.
+	+ add xtermm and xtermc terminfo entries.
+	> from esr's terminfo version:
+	+ Added Francesco Potorti's tuned Wyse 99 entries.
+	+ dtterm enacs (from Alexander V Lukyanov).
+	+ Add ncsa-ns, ncsa-m-ns and ncsa-m entries from esr version.
+
+980822
+	+ document AT&T acs characters in terminfo.5 manpage.
+	+ use EMX _scrsize() function if terminfo and environment do not
+	  declare the screen size (reported by Ilya Zakharevich
+	  <ilya@math.ohio-state.edu>).
+	+ remove spurious '\' characters from eterm and osborne terminfo
+	  entries (prompted by an old Debian bug report).
+	+ correct reversed malloc/realloc calls in _nc_doalloc (reported by
+	  Hans-Joachim Widmaier <hjwidmai@foxboro.com>).
+	+ correct misplaced parenthesis which caused file-descriptor from
+	  opening termcap to be lost, from 980725 changes (reported by Andreas
+	  Jaeger).
+
+980815
+	+ modify lib_setup.c to eliminate unneeded include of <sys/ioctl.h>
+	  when termios is not used (patch by Todd C Miller).
+	+ add function _nc_doalloc, to ensure that failed realloc calls do not
+	  leak memory (reported by Todd C Miller).
+	+ improved ncsa-telnet terminfo entry.
+
+980809
+	+ correct missing braces around a trace statement in read_entry.c,
+	  from 980808 (reported by Kim DeVaughn <kimdv@best.com> and Liviu
+	  Daia).
+
+980808
+	+ fix missing include <errno.h> in ditto.c (reported by Bernhard
+	  Rosenkraenzer <bero@k5.sucks.eu.org>)
+	+ add NCSA telnet terminfo entries from Francesco Potorti
+	  <F.Potorti@cnuce.cnr.it>, from Debian bug reports.
+	+ make handling of $LINES and $COLUMNS variables more compatible with
+	  Solaris by allowing them to individually override the window size
+	  as obtained via ioctl.
+
+980801
+	+ modify lib_vidattr.c to allow for terminal types (e.g., xterm-color)
+	  which may reset all attributes in the 'op' capability, so that colors
+	  are set before turning on bold and other attributes, but still after
+	  turning attributes off.
+	+ add 'ditto.c' to test directory to illustrate use of newterm for
+	  initializing multiple screens.
+	+ modify _nc_write_entry() to recover from failed attempt to link alias
+	  for a terminfo on a filesystem which does not preserve character case
+	  (reported by Peter L Jordan <PJordan@chla.usc.edu>).
+
+980725
+	+ updated versions of config.guess and config.sub based on automake 1.3
+	+ change name-comparisons in lib_termcap to compare no more than 2
+	  characters (gleaned from Debian distribution of 1.9.9g-8.8, verified
+	  with Solaris curses).
+	+ fix typo in curs_insstr.3x (patch by Todd C Miller)
+	+ use 'access()' to check if ncurses library should be permitted to
+	  open or modify files with fopen/open/link/unlink/remove calls, in
+	  case the calling application is running in setuid mode (request by
+	  Cristian Gafton <gafton@redhat.com>, responding to Duncan Simpson
+	  <dps@io.stargate.co.uk>).
+	+ arm100 terminfo entries from Dave Millen <dmill@globalnet.co.uk>).
+	+ qnxt2 and minitel terminfo entries from esr's version.
+
+980718
+	+ use -R option with ldconfig on FreeBSD because otherwise it resets
+	  the search path to /usr/lib (reported by Dan Nelson).
+	+ add -soname option when building shared libraries on OpenBSD 2.x
+	  (request by QingLong).
+	+ add configure options --with-manpage-format and
+	  --with-manpage-renames (request by QingLong).
+	+ correct conversion of CANCELLED_NUMERIC in write_object(), which was
+	  omitting the high-order byte, producing a 254 in the compiled
+	  terminfo.
+	+ modify return-values of tgetflag, tgetnum, tgetstr, tigetflag,
+	  tigetnum and tigetstr to be compatible with Solaris (gleaned from
+	  Debian distribution of 1.9.9g-8.8).
+	+ modify _nc_syserr_abort to abort only when compiled for debugging,
+	  otherwise simply exit with an error.
+
+980711
+	+ modify Ada95 'gen' program to use appropriate library suffix (e.g.,
+	  "_g" for a debug build).
+	+ update Ada95 'make clean' rule to include generics .ali files
+	+ add a configure test to ensure that if GNAT is found, that it can
+	  compile/link working Ada95 program.
+	+ flush output in beep and flash functions, fixing a problem with
+	  getstr (patch by Alexander V Lukyanov)
+	+ fix egcs 1.0.2 warning for etip.h (patch by Chris Johns).
+	+ correct ifdef/brace nesting in lib_sprintf.c (patch by Bernhard
+	  Rosenkraenzer <bero@Pool.Informatik.RWTH-Aachen.DE>).
+	+ correct typo in wattr_get macro from 980509 fixes (patch by Dan
+	  Nelson).
+
+980704
+	+ merge changes from current XFree86 xterm terminfo descriptions.
+	+ add configure option '--without-ada'.
+	+ add a smart-default for termcap 'ac' to terminfo 'acs_chars' which
+	  corresponds to vt100.
+	+ change translation for termcap 'rs' to terminfo 'rs2', which is
+	  the documented equivalent, rather than 'rs1'.
+
+980627
+	+ slow 'worm' down a little, for very fast machines.
+	+ corrected firstchar/lastchar computation in lib_hline.c
+	+ simplify some expressions with CHANGED_CELL, CHANGED_RANGE and
+	  CHANGED_TO_EOL macros.
+	+ modify init_pair so that if a color-pair is reinitialized, we will
+	  repaint the areas of the screen whose color changes, like SVr4 curses
+	  (reported by Christian Maurer <maurer@inf.fu-berlin.de>).
+	+ modify getsyx/setsyx macros to comply with SVr4 man-page which
+	  says that leaveok() affects their behavior (report by Darryl Miles,
+	  patch by Alexander V Lukyanov).
+
+980620
+	+ review terminfo.5 against Solaris 2.6 curses version, corrected
+	  several minor errors/omissions.
+	+ implement tparm %l format.
+	+ implement tparm printf-style width and precision for %s, %d, %x, %o
+	  as per XSI.
+	+ implement tparm dynamic variables (reported by Xiaodan Tang).
+
+980613
+	+ update man-page for for wattr_set, wattr_get (cf:  980509)
+	+ correct limits in hashtest, which would cause nonprinting characters
+	  to be written to large screens.
+	+ correct configure script, when --without-cxx was specified:  the
+	  wrong variable was used for cf_cv_type_of_bool.  Compilers up to gcc
+	  2.8 tolerated the missing 'int'.
+	+ remove the hardcoded name "gcc" for the GNU Ada compiler.  The
+	  compiler's name might be something like "egcs" (patch by Juergen
+	  Pfeifer).
+	+ correct curs_addch.3x, which implied that echochar could directly
+	  display control characters (patch by Alexander V Lukyanov).
+	+ fix typos in ncurses-intro.html (patch by Sidik Isani
+	  <isani@cfht.hawaii.edu>)
+
+980606
+	+ add configure test for conflicting use of exception in math.h and
+	  other headers.
+	+ minor optimization to 'hash()' function in hashmap.c, reduces its
+	  time by 10%.
+	+ correct form of LD_SHARED_OPTS for HP-UX 10.x (patch by Tim Mooney).
+	+ fix missing quotes for 'print' in MKunctrl.awk script (reported by
+	  Mihai Budiu <mihaib@gs41.sp.cs.cmu.edu>).
+	> patch by Alexander V Lukyanov:
+	+ correct problem on Solaris (with poll() function) where getch could
+	  hang indefinitely even if timeout(x) was called.  This turned out to
+	  be because milliseconds was not updated before 'goto retry' in
+	  _nc_timed_wait.
+	+ simplified the function _nc_timed_wait and fixed another bug, which
+	  was the assumption of !GOOD_SELECT && HAVE_GETTIMEOFDAY in *timeleft
+	  assignment.
+	+ removed the cycle on EINTR, as it seems to be useless.
+
+980530
+	+ add makefile-rule for test/keynames
+	+ modify run_tic.sh and shlib to ensure that user's .profile does not
+	  override the $PATH used to run tic (patch by Tim Mooney).
+	+ restore LD_SHARED_OPTS to $(LD_SHARED_FLAGS) when linking programs,
+	  needed for HP-UX shared-library path (recommended by Tim Mooney).
+	+ remove special case of HP-UX -L options, use +b options to embed
+	  $(libdir) in the shared libraries (recommended by Tim Mooney).
+	+ add checks for some possible buffer overflows and unchecked
+	  malloc/realloc/calloc/strdup return values (patch by Todd C Miller
+	  <Todd.Miller@courtesan.com>)
+
+980523
+	+ correct maxx/maxy expression for num_columns/num_lines in derwin
+	  (patch by Alexander V Lukyanov).
+	+ add /usr/share/lib/terminfo and /usr/lib/terminfo as compatibility
+	  fallbacks to _nc_read_entry(), along with --with-terminfo-dirs
+	  configure option (suggested by Mike Hopkirk).
+	+ modify config.guess to recognize Unixware 2.1 and 7 (patch by Mike
+	  Hopkirk <hops@sco.com>).
+	+ suppress definition of CC_SHARED_OPTS in LDFLAGS_SHARED in c++
+	  Makefile.in, since this conflicts when g++ is used with HP-UX
+	  compiler (reported by Tim Mooney).
+	+ parenthesize 'strcpy' calls in c++ binding to workaround redefinition
+	  in some C++ implementations (reported by several people running
+	  egcs with glibc 2.0.93, analysis by Andreas Jaeger.
+
+980516
+	+ modify write_entry.c so that it will not attempt to link aliases
+	  with embedded '/', but give only a warning.
+	+ put -L$(libdir) first when linking programs, except for HP-UX.
+	+ modify comp_scan.c to handle SVr4 terminfo description for att477,
+	  which contains a colon in the description field.
+	+ modify configure script to support SCO osr5.0.5 shared libraries,
+	  from comp.unix.sco.programmer newsgroup item (Mike Hopkirk).
+	+ eliminate extra GoTo call in lib_doupdate.c (patch by Alexander V.
+	  Lukyanov).
+	+ minor adjustments of const/NCURSES_CONST from IRIX compile.
+	+ add updates based on esr's 980509 version of terminfo.src.
+
+980509
+	+ correct macros for wattr_set, wattr_get, separate wattrset macro from
+	  these to preserve behavior that allows attributes to be combined with
+	  color pair numbers.
+	+ add configure option --enable-no-padding, to allow environment
+	  variable $NCURSES_NO_PADDING to eliminate non-mandatory padding,
+	  thereby making terminal emulators (e.g., for vt100) a little more
+	  efficient (request by Daniel Eisenbud <eisenbud@cs.swarthmore.edu>).
+	+ modify configure script to embed ABI in shared libraries for HP-UX
+	  10.x (detailed request by Tim Mooney).
+	+ add test/example of the 'filter()' function.
+	+ add nxterm and xterm-color terminfo description (request by Cristian
+	  Gafton <gafton@redhat.com>).
+	+ modify rxvt terminfo description to clear alternate screen before
+	  switching back to normal screen, for compatibility with applications
+	  which use xterm (reported by Manoj Kasichainula <manojk@io.com>).
+	+ modify linux terminfo description to reset color palette (reported
+	  by Telford Tendys <telford@eng.uts.edu.au>).
+	+ correction to doupdate, for case where terminal does not support
+	  insert/delete character.  The logic did not check that there was a
+	  difference in alignment of changes to old/new screens before
+	  repainting the whole non-blank portion of the line.  Modified to fall
+	  through into logic that reduces by the portion which does not differ
+	  (reported by Daniel Eisenbud <eisenbud@cs.swarthmore.edu>).
+	+ minor performance improvement to wnoutrefresh by moving some
+	  comparisons out of inner loop.
+
+980425
+	+ modify configure script to substitute NCURSES_CONST in curses.h
+	+ updated terminfo entries for xterm-xf86-v40, xterm-16color,
+	  xterm-8bit to correspond to XFree86 3.9Ag.
+	+ remove restriction that forces ncurses to use setaf/setab if the
+	  number of colors is greater than 8.  (see 970524 for xterm-16color).
+	+ change order of -L options (so that $(libdir) is searched first) when
+	  linking tic and other programs, to workaround HP's linker.
+	  Otherwise, the -L../lib is embedded when linking against shared
+	  libraries and the installed program does not run (reported by Ralf
+	  Hildebrandt).
+	+ modify configuration of shared libraries on Digital Unix so that
+	  versioning is embedded in the library, rather than implied by
+	  links (patch by Tim Mooney).
+
+980418
+	+ modify etip.h to avoid conflict with math.h on HP-UX 9.03 with gcc
+	  2.8.1 which redefines 'exception' (reported by Ralf Hildebrandt
+	  <R.Hildebrandt@tu-bs.de>).
+	+ correct configure tests in CF_SHARED_OPTS which used $CC value to
+	  check for gcc, rather than autoconf's $GCC value.  This did not
+	  work properly if the full pathname of the compiler were given
+	  (reported by Michael Yount <yount@csf.Colorado.edu>).
+	+ revise check for compiler options to force ANSI mode since repeating
+	  an option such as -Aa causes HP's compiler to fail on its own headers
+	  (reported by Clint Olsen <olsenc@ichips.intel.com>).
+
+980411
+	+ ifdef'd has_key() and mcprint() as extended functions.
+	+ modified several prototypes to correspond with 1997 version of
+	  X/Open Curses (affects ABI since developers have used attr_get).
+	+ remove spurious trailing blanks in glibc addon-scripts (patch by
+	  H.J.Lu).
+	+ insert a few braces at locations where gcc-2.8.x asks to use them to
+	  avoid ambiguous else's, use -fpic rather than -fPIC for Linux (patch
+	  by Juergen Pfeifer).
+
+980404
+	+ split SHLIB_LIST into SHLIB_DIRS/SHLIB_LIST to keep -L options
+	  before -l to accommodate Solaris' linker (reported by Larry Virden).
+
+980328
+	+ modify lib_color.c to eliminate dependency on orig_colors and
+	  orig_pair, since SVr4 curses does not require these either, but
+	  uses them when they are available.
+	+ add detailed usage-message to infocmp.
+	+ correct a typo in att6386 entry (a "%?" which was "?").
+	+ add -f option to infocmp and tic, which formats the terminfo
+	  if/then/else/endif so that they are readable (with newlines and
+	  tabs).
+	+ fixes for glibc addon scripts (patch by H.J.Lu).
+
+980321
+	+ revise configure macro CF_SPEED_TYPE so that termcap.h has speed_t
+	  declared (from Adam J Richter <adam@yggdrasil.com>)
+	+ remove spurious curs_set() call from leaveok() (J T Conklin).
+	+ corrected handling leaveok() in doupdate() (patch by Alexander V.
+	  Lukyanov).
+	+ improved version of wredrawln (patch by Alexander V. Lukyanov).
+	+ correct c++/Makefile.in so install target do not have embedded ../lib
+	  to confuse it (patch by Thomas Graf <graf@essi.fr>).
+	+ add warning to preinstall rule which checks if the installer would
+	  overwrite a curses.h or termcap.h that is not derived from ncurses.
+	  (The recommended configuration for developers who need both is to
+	  use --disable-overwrite).
+	+ modify preinstall rule in top-level Makefile to avoid implicit
+	  use of 'sh', to accommodate Ultrix 4.4 (reported by Joao Palhoto
+	  Matos <jmatos@math.ist.utl.pt>, patch by Thomas Esser
+	  <te@informatik.uni-hannover.de>)
+	+ refine ifdef's for TRACE so that libncurses has fewer dependencies
+	  on libtinfo when TRACE is disabled.
+	+ modify configure script so that if the --with-termlib option is used
+	  to generate a separate terminfo library, we chain it to the ncurses
+	  library with a "-l" option (reported by Darryl Miles and Ian T.
+	  Zimmerman).
+
+980314
+	+ correct limits and window in wredrawln function (reported/analysis by
+	  Alexander V. Lukyanov).
+	+ correct sed expression in configure script for --with-fallback
+	  option (patch by Jesse Thilo).
+	+ correct some places in configure script where $enableval was used
+	  rather than $withval (patch by Darryl Miles <dlm@g7led.demon.co.uk>).
+	+ modify some man-pages so no '.' or '..' falls between TH and SH
+	  macros, to accommodate man_db program (reported by Ian T. Zimmerman
+	  <itz@rahul.net>).
+	+ terminfo.src 10.2.1 downloaded from ESR's webpage (ESR).
+	> several changes by Juergen Pfeifer:
+	+ add copyright notices (and rcs id's) on remaining man-pages.
+	+ corrected prototypes for slk_* functions, using chtype rather than
+	  attr_t.
+	+ implemented the wcolor_set() and slk_color() functions
+	+ the slk_attr_{set,off,on} functions need an additional void*
+	  parameter according to XSI.
+	+ fix the C++ and Ada95 binding as well as the man pages to
+	  reflect above enhancements.
+
+980307
+	+ use 'stat()' rather than 'access()' in toe.c to check for the
+	  existence of $HOME/.terminfo, since it may be a file.
+	+ suppress configure CF_CXX_LIBRARY check if we are not using g++
+	  2.7.x, since this is not needed with g++ 2.8 or egcs (patch by
+	  Juergen Pfeifer).
+	+ turn on hashmap scrolling code by default, intend to remedy defects
+	  by 4.3 release.
+	+ minor corrections to terminfo.src changelog.
+
+980302	4.2 release for upload to prep.ai.mit.edu
+	+ correct Florian's email address in ncurses-intro.html
+	+ terminfo.src 10.2.0 (ESR).
+
+980228	pre-release
+	+ add linux-koi8r replace linux-koi8, which is not KOI8 (patch by
+	  QingLong <qinglong@Bolizm.ihep.su>).
+	+ minor documentation fixes (patch by Juergen Pfeifer).
+	+ add setlocale() call to ncurses.c (reported by Claes G. Lindblad
+	  <claesg@algonet.se>).
+	+ correct sign-extension in lib_insstr.c (reported by Sotiris
+	  Vassilopoulos <svas@leon.nrcps.ariadne-t.gr>)
+
+980221	pre-release
+	+ regenerated some documentation overlooked in 980214 patch
+	  (ncurses-intro.doc, curs_outopts.3x.html)
+	+ minor ifdef change to C++ binding to work with gcc 2.8.0 (patch by
+	  Juergen Pfeifer).
+	+ change maintainer's mailing address to florian@gnu.org, change
+	  tentative mailing list address to bug-ncurses-request@gnu.org (patch
+	  by Florian La Roche).
+	+ add definition of $(REL_VERSION) to c++/Makefile.in (reported by Gran
+	  Hasse <gh@raditex.se>).
+	+ restore version numbers to Ada95 binding, accidentally deleted by
+	  copyright patch (patch by Juergen Pfeifer).
+
+980214	pre-release
+	+ remove ncurses.lsm from MANIFEST so that it won't be used in FSF
+	  distributions, though it is retained in development.
+	+ correct scaling of milliseconds to nanoseconds in lib_napms.c (patch
+	  by Jeremy Buhler).
+	+ update mailing-list information (bug-ncurses@gnu.org).
+	+ update announcement for upcoming 4.2 release.
+	+ modify -lm test to check for 'sin()' rather than 'floor()'
+	+ remove spurious commas from terminfo.src descriptions.
+	+ change copyright notices to Free Software Foundation
+
+980207
+	+ minor fixes for autoconf macros CF_ERRNO, CF_HELP_MESSAGE and
+	  CF_SIZECHANGE
+	+ modify Makefile.glibc so that $(objpfx) is defined (H.J.Lu).
+	+ ifdef-out true-return from _nc_mouse_inline() which depends on
+	  merge of QNX patch (pending 4.2 release).
+	> patch to split off seldom-used modules in ncurses (J T Conklin):
+	  This reduces size by up to 2.6kb.
+	+ move functionality of _nc_usleep into napms, add configuration case
+	  for nanosleep().
+	+ moved wchgat() from lib_addch.c to lib_chgat.c
+	+ moved clearok(), immedok(), leaveok(), and scrollok() from
+	  lib_options.c to lib_clearok.c, lib_immedok.c, lib_leaveok.c and
+	  lib_scrollok.c.
+	+ moved napms() from lib_kernel.c to lib_napms.c
+	+ moved echo() and noecho() from lib_raw.c to lib_echo.c
+	+ moved nl() and nonl() from lib_raw.c to lib_nl.c
+
+980131
+	+ corrected conversion in tclock.c (cf: 971018).
+	+ updates to Makefile.glibc and associated Linux configure script
+	  (patch by H.J.Lu).
+	+ workaround a quoting problem on SunOS with tar-copy.sh
+	+ correct init_pair() calls in worm.c to work when use_default_colors()
+	  is not available.
+	+ include <sys/types.h> in CF_SYS_TIME_SELECT to work with FreeBSD
+	  2.1.5
+	+ add ncv capability to FreeBSD console (cons25w), making reverse
+	  work with color.
+	+ correct sense of configure-test for sys/time.h inclusion with
+	  sys/select.h
+	+ fixes for Ada95/ada_include/Makefile.in to work with --srcdir option.
+	+ remove unused/obsolete test-program rules from progs/Makefile.in
+	  (the rules in ncurses/Makefile.in work).
+	+ remove shared-library loader flags from test/Makefile.in, etc.
+	+ simplify test/configure.in using new version of autoconf to create
+	  test/ncurses_cfg.h
+	+ suppress suffix rules in test/Makefile.in, provide explicit
+	  dependency to work with --srcdir option and less capable 'make'
+	  programs.
+	> adapted from patch for QNX by Xiaodan Tang:
+	+ initialize %P and %g variables set/used in tparm, and also ensure
+	  that empty strings don't return a null result from tparam_internal
+	+ add QNX-specific prototype for vsscanf()
+	+ move initialization of SP->_keytry from init_keytry() to newterm() to
+	  avoid resetting it via a keyok() call by mouse_activate().
+	+ reorganized some functions in lib_mouse() to use case-statements.
+	+ remove sgr string from qnx terminfo entry since it is reported to
+	  turn off attributes inconsistently.
+
+980124
+	+ add f/F/b/B commands to ncurses 'b' test to toggle colors, providing
+	  test for no_color_video.
+	+ adjusted emx.src to use no_color_video, now works with ncurses 'b'
+	  and 'k' tests.
+	+ implement no_color_video attribute, and as a special case, reverse
+	  colors when the reverse attribute cannot be combined with color.

+	+ modify CF_BOOL_SIZE to check if C++ bool types are unsigned.
+	> patches by J.J.G.Ripoll
+	+ add configure/makefile variables to support .exe extension on
+	  OS/2 EMX (requires additional autoconf patches).
+	+ explicitly initialize variables in lib_data.c to appease OS/2 linker
+	> patches by Fred Fish <fnf@ninemoons.com>
+	+ misc/Makefile.in (install.data):  Avoid trying to install the CVS
+	  directory.
+	+ aclocal.m4 (install.includes):  Remove files in the include directory
+	  where we are going to install new ones, not the original source
+	  files.
+	+ misc/terminfo.src:  Add entry for "beterm", derived from termcap
+	  distributed with BeOS PR2 using captoinfo.
+	+ aclocal.m4: Wrap $cf_cv_type_of_bool with quotes (contains space)
+	+ aclocal.m4: Assume bool types are unsigned.
+	+ progs/infocmp.c: workaround mwcc 32k function data limit
+
+980117
+	+ correct initialization of color-pair (cf: 970524) in xmas.c, which
+	  was using only one color-pair for all colors (reported by
+	  J.J.G.Ripoll).
+	+ add multithread options for objects build on EMX, for compatibility
+	  with XFree86.
+	+ split up an expression in MKlib_gen.sh to work around a problem on
+	  OS/2 EMX, with 'ash' (patch by J.J.G.Ripoll).
+	+ change terminfo entries xterm (xterm-xf86-v40), xterm-8bit rs1 to use
+	  hard reset.
+	+ rename terminfo entry xterm-xf86-v39t to xterm-xf86-v40
+	+ remove bold/underline from sun console entries since they're not
+	  implemented.
+	+ correct _tracef calls in _tracedump(), which did not separate format
+	  from parameters.
+	+ correct getopt string for tic "-o" option, and add it to man-page
+	  synopsis (reported by Darren Hiebert <darren@hmi.com>).
+	+ correct typo in panel/Makefile.in, reversed if-statement in scrolling
+	  optimization (Alexander V.  Lukyanov).
+	+ test for 'remove()', use 'unlink() if not found (patch by Philippe De
+	  Muyter <phdm@macqel.be>).
+	> patches by Juergen Pfeifer:
+	+ Improve a feature of the forms driver.  For invisible fields
+	  (O_VISIBLE off) only the contents but not the attributes are cleared.
+	  We now clear both.  (Reported by Javier Kohan
+	  <jkohan@adan.fceia.unr.edu.ar>)
+	+ The man page form_field_opts.3x makes now clear, that invisible
+	  fields are also always inactive.
+	+ adjust ifdef's to compile the C++ binding with the just released
+	  gcc-2.8.0 c++ and the corresponding new C++ libraries.
+
+980110
+	+ correct "?" command in ncurses.c; it was performing non-screen writes
+	  while the program was in screen mode.  (It "worked" in 1.9.9e because
+	  that version sets OPOST and OCRNL incorrectly).
+	+ return error from functions in lib_kernel, lib_raw and lib_ti if
+	  cur_term is null, or if underlying I/O fails.
+	+ amend change to tputs() so that it does not return an error if
+	  cur_term is null, since some applications depend on being able to use
+	  tputs without initializing the terminal (reported by Christian J.
+	  Robinson <infynity@cyberhighway.net>).
+
+980103
+	+ add a copy of emx.src from J.J.G.Ripoll's OS/2 EMX version of ncurses
+	  1.9.9e, together with fixes/additions for the "ansi" terminal type.
+	+ add tic check for save/restore cursor if change_scroll_region is
+	  defined (reference: O'Reilly book).
+	+ modify read_termcap.c to handle EMX-style pathnames (reported by
+	  J.J.G.Ripoll).
+	+ modify lib_raw.c to use EMX's setmode (patch from J.J.G.Ripoll).
+	  Ripoll says EMX's curses does this.
+	+ modify _nc_tic_expand() to generate \0 rather than \200.
+	+ move/revise 'expand()' from dump_entry.c to ncurses library as
+	  _nc_tic_expand(), for use by tack.
+	+ decode \a as \007 for terminfo, as per XSI.
+	+ correct translation of terminfo "^@", to \200, like \0.
+	+ modify next_char() to treat <cr><lf> the same as <newline>, for
+	  cross-platform compatibility.
+	+ use new version of autoconf (971230) to work around limited
+	  environment on CLIX, due to the way autoconf builds --help message.
+	> patch by Juergen Pfeifer:
+	+ check that the Ada95 binding runs against the correct version of
+	  ncurses.
+	+ insert constants about the library version into the main spec-file of
+	  the Ada95 binding.
+
+971227
+	+ modify open/fopen calls to use binary mode, needed for EMX.
+	+ modify configure script to work with autoconf 2.10 mods for OS/2
+	  EMX (from J.J.G.Ripoll).
+	+ generated ncurses_cfg.h with patch (971222) to autoconf 2.12 which
+	  bypasses limited sed buffer length.
+	> several changes from Juan Jose Garcia Ripoll <worm@arrakis.es>
+	  (J.J.G.Ripoll) to support OS/2 EMX:
+	+ add a _scrolling flag to SP, to set when we encounter a terminal
+	  that simply cannot scroll.
+	+ corrected logic in _nc_add_to_try(), by ensuring that strings with
+	  embedded \200 characters are matched.
+	+ don't assume the host has 'link()' function, for linking terminfo
+	  entries.
+
+971220
+	+ if there's no ioctl's to support sigwinch handler, disable it.
+	+ add configure option --disable-ext-funcs to remove the extended
+	  functions from the build.
+	+ add configure option --with-termlib to generate the terminfo
+	  functions as a separate library.
+	+ add 'sources' rule to facilitate cross-compiling.
+	+ review/fix order of mostlyclean/clean/distclean rules.
+	+ modify install-rule for headers to first remove old header, in
+	  case there was a symbolic link that confuses the install script.
+	+ corrected substitution for NCURSES_CONST in term.h (cf: 971108)
+	+ add null pointer checks in wnoutrefresh(), overlap() (patch by
+	  Xiaodan Tang <xtang@qnx.com>)
+	+ correct tputs(), which could dereference a null cur_term if invoked
+	  before terminal is initialized (patch by Christopher Seawood
+	  <cls@seawood.org>)
+	> patch by Juergen Pfeifer:
+	+ makes better use of "pragma Inline" in the Ada95 binding
+	+ resynchronizes the generated html manpages
+
+971213
+	+ additional fixes for man-pages section-references
+	+ add (for debugging) a check for ich/ich1 conflict with smir/rmir
+	  to tic, etc.
+	+ remove hpa/vpa from rxvt terminal description because they are not
+	  implemented correctly, added sgr0.
+	+ change ncurses 's' to use raw mode, so ^Q works (reported by Rudolf
+	  Leitgeb <leitgeb@leland.stanford.edu>)
+
+971206
+	+ modify protection when installing libraries to (normally) not
+	  executable.  HP-UX shared libraries are an exception.
+	+ add configure check for 'tack'.
+	+ implement script for renaming section-references in man-page install,
+	  for Debian configuration.
+	+ add validity-check for SP in trace code in baudrate() (reported by
+	  Daniel Weaver).
+	> patch by Alexander V. Lukyanov (fixes to match sol25 curses)
+	+ modify 'overlay()' so that copy applies target window background to
+	  characters.
+	+ correct 'mvwin()' so that it does not clear the previous locations.
+	+ correct lib_acs.c so that 8-bit character is not sign expanded in
+	  case of wide characters in chtype.
+	+ correct control-char test in lib_addch.c for use with wide chars
+	+ use attribute in the chtype when adding a control character in
+	  lib_addch.c control char was added with current attribute
+
+971129
+	+ save/restore errno in _tracef() function
+	+ change treatment of initialize_color to use a range of 0..1000
+	  (recommended by Daniel Weaver).
+	+ set umask in mkinstalldirs, fixing problems reported by users who
+	  have set root's umask to 077.
+	+ correct bug in tic that caused capabilities to be reprinted at the
+	  end of output when they had embedded comments.
+	+ rewrote wredrawln to correspond to XSI, and split-out since it is
+	  not often used (from report by Alexander V. Lukyanov, 970825)
+	+ rewrote Dan Nelson's change to make it portable, as well as to
+	  correct logic for handling backslashes.
+	+ add code to _nc_tgetent() to make it work more like a real tgetent().
+	  It removes all empty fields, and removes all but the first in a group
+	  of duplicate caps.  The code was pulled from the BSD libtermcap code
+	  in termcap.c (patch by Dan Nelson <dnelson@emsphone.com>
+	+ don't include --enable-widec in the --with-develop configure option,
+	  since it is not binary-compatible with 4.1 (noted by Alexander V.
+	  Lukyanov)
+	> patch by Juergen Pfeifer:
+	+ further improvements of the usage of elaboration pragmas in the Ada95
+	  binding
+	+ enhanced Ada95 sample to use the user_data mechanism for panels.
+	+ a fix for the configuration script to make gnat-3.10 the required

+	+ resync of the html version of the manpages
+
+971122
+	> fixes/updates for terminfo.src:
+	+ add vt220-js, pilot, rbcomm, datapoint entries from esr's 27-jun-97
+	  version.
+	+ add hds200 description (Walter Skorski)
+	+ add EMX 0.9b descriptions
+	+ correct rmso/smso capabilities in wy30-mc and wy50-mc (Daniel Weaver)
+	+ rename xhpterm back to hpterm.
+	> patch by Juergen Pfeifer:
+	+ Improves the usage of elaboration pragmas for the Ada95 binding.
+	+ Adds a translation of the test/rain.c into Ada95 to the samples.
+	  This has been contributed to the project by Laurent Pautet
+	  (pautet@gnat.com)
+
+971115
+	+ increase MAX_NAME_SIZE to 512 to handle extremely long alias list
+	  in HP-UX terminfo.
+	+ correction & simplification of delay computation in tputs, based on
+	  comments from Daniel Weaver.
+	+ replace test for SCO with more precise header tests.
+	+ add configure test for unsigned literals, use in NCURSES_BITS macro.
+	+ comment-out the -PIC, etc., flags from c++, progs and test makefiles
+	  since they probably are not needed, and are less efficient (noted by
+	  Juergen Fluk)
+	+ add -L$(libdir) to loader options, after -L../lib so that loaders
+	  that record this information will tend to do the right thing if
+	  the programs are moved around after installing them (suggested by
+	  Juergen Fluk).
+	+ add -R option to loader options for programs for Solaris if the
+	  --enable-rpath option is specified for the libraries.
+
+971112
+	+ correct installed filename for shared libraries on *BSD (reported by
+	  Juergen Fluk).
+
+971108
+	+ cleanup logic for deciding when tputs() should call delay_output(),
+	  based on comments from Daniel Weaver.
+	+ modified tputs() to avoid use of float.
+	+ correct use of trailpad in tputs(), which used the wrong variable
+	  in call to delay_output().
+	+ correct inverted expression for null-count in delay_output()
+	  (analysis by Daniel Weaver).
+	+ apply --enable-rpath option to Solaris (requested by Larry Virden).
+	+ correct substitution of EXTRA_CFLAGS for gcc 2.6.3
+	+ correct check for error-return by _nc_tgetent(), which returns 0
+	  for success.
+	+ add configure test for BSD 4.4 cgetent() function, modify
+	  read_termcap.c to use the host's version of that if found, using the
+	  terminal database on FreeBSD (reported by Peter Wemm).
+	+ add u8, u9 strings to sun-il description for Daniel Weaver.
+	+ use NCURSES_CONST in panel's user-pointer.
+	+ modify edit_cfg.sh and MKterm.h.awk.in to substitute NCURSES_CONST
+	  so that will work on NeXT.
+	+ use _nc_set_screen() rather than assignments to SP to fix port to
+	  NeXT (reported by Francisco A. Tomei Torres).
+
+971101
+	+ force mandatory padding in bell and flash_screen, as specified in
+	  XSI.
+	+ don't allow padding_baud_rate to override mandatory delays (reported
+	  by Daniel Weaver).
+	+ modify delay_output() to use _nc_timed_wait() if no baudrate has been
+	  defined, or if the cur_term pointer is not initialized.  XSI treats
+	  this as unspecified.  (requested by Daniel Weaver).
+	+ change getcap-cache ifdef's to eliminate unnecessary chdir/mkdir
+	  when that feature is not configured.
+	+ remove _nc_err_abort() calls when write_entry.c finds a directory but
+	  cannot write to it, e.g., when translating part/all of /etc/termcap
+	  (reported by Andreas Jaeger <aj@arthur.rhein-neckar.de>).
+	  (this dates back to 951102 in 1.9.7a).
+	+ minor ifdef fixes to compile with atac and glibc 2.0.5c
+	+ add check for -lgen when configuring regexpr.h
+	+ modify Solaris shared-library option "-d y" to "-dy" to workaround
+	  incompatibility of gcc 2.7.2 vs vendor's tools.
+
+971026
+	+ correct ifdef's for struct winsize vs struct ttysize in lib_setup.c
+	  to compile on SCO.
+	+ remove dangling backslash in panel/Makefile.in
+	+ modify MKkeyname.awk to work with SCO's nawk, which dumps core in the
+	  length() function.
+	+ correct length of allocation in _nc_add_to_try(), to allow for
+	  trailing null.
+	+ correct logic in _nc_remove_key(), which was discarding too many
+	  nodes (patch by Alexander V. Lukyanov)
+
+971025
+	+ add definition for $(REL_VERSION) to test/Makefile.in, so *BSD
+	  shared libraries link properly (see 970524).
+	+ modify Linux shared-library generation to include library
+	  dependencies (e.g., -lncurses and -lgpm) in the forms, menu and
+	  panel libraries (suggested by Juergen Pfeifer).
+	+ modify configure script to use config.guess and config.sub rather
+	  than uname, which is unreliable on some systems.
+	+ updated Makefile.glibc, test-built with glibc 2.0.5c
+	+ modify keyname() to return values consistent with SVr4 curses (patch
+	  by Juergen Fluk).
+	> changes requested by Daniel Weaver:
+	+ modify delay_output() so that it uses the same output function as
+	  tputs() if called from that function.
+	+ move _baudrate from SCREEN to TERMINAL so that low-level use of
+	  tputs works when SP is not set.
+	> patch by Juergen Pfeifer:
+	+ factor lib_menu and lib_form into smaller modules
+	+ clean up the interface between panel and SCREEN
+	+ minor changes to the Ada95 mouse support implementation
+	+ minor bugfix in C++ binding to ripoff windows
+	+ fix a few Ada95 html documentation pages
+
+971018
+	+ split-out lib_ungetch.c, make runtime link to resizeterm() to
+	  decouple those modules from lib_restart.c
+	+ add xterm-xf86-v39t description to terminfo.src
+	+ reset SP->_endwin in lib_tstp.c cleanup() function after calling
+	  endwin() to avoid unnecessary repainting if the application has
+	  established an atexit function, etc.  Encountered this problem in
+	  the c++ demo, whose destructors repaint the screen.
+	+ combine _nc_get_screensize() and resizeterm() calls as new function
+	  _nc_update_screensize().
+	+ minor fixes to allow compile with g++ (suggested by Nelson H. F.
+	  Beebe).
+	+ implement install-rules for Ada95 makefiles.
+	+ use screen_lines or MAXLINES as needed where LINES was coded,
+	  as well as screen_columns for COLS, in the ncurses library.
+	> patch by Alexander V. Lukyanov:
+	+ modify logic for ripped-off lines to handle several SCREENs.
+	> patch by Juergen Pfeifer:
+	+ factors lib_slk.c into some smaller modules
+	+ factors panel.c into some smaller modules
+	+ puts the static information about the current panel stack into the
+	  SCREEN structure to allow different panel stacks on different
+	  screens.
+	+ preliminary fix for an error adjusting LINES to account for
+	  ripped-off lines.
+
+971011
+	+ move _nc_max_click_interval and other mouse interface items to SCREEN
+	  struct so that they are associated with a single terminal, and also
+	  save memory when the application does not need a mouse (roughly 3k vs
+	  0.5k on Linux).
+	+ modify mouseinterval() so that a negative parameter queries the
+	  click-interval without modifying it.
+	+ modify ncurses 'i' test to work with ncurses' apparent extension from
+	  SVr4, i.e., allows nocbreak+noecho (analysis by Alexander V.
+	  Lukyanov).
+	+ add configure options --with-ada-includes and --with-ada-objects,
+	  to drive Ada95 binding install (not yet implemented).
+	+ install C++ binding as -lncurses++ and associated headers with the
+	  other ncurses headers.
+	+ fix header uninstall if configure --srcdir is used.
+	> minor interface changes to support 'tack' program -TD
+	  (request by Daniel Weaver <danw@znyx.com>).
+	+ export functions _nc_trans_string() and _nc_msec_cost().
+	+ add variable _nc_nulls_sent, to record the number of padding
+	  characters output in delay_output().
+	+ move tests for generic_type and hard_copy terminals in setupterm()
+	  to the end of that function so that the library will still be
+	  initialized, though not generally useful for curses programs.
+	> patches by Alexander V. Lukyanov:
+	+ modify ClrBottom() to avoid using clr_eos if there is only one line
+	  to erase.
+	+ typo in configure --help.
+	> patch by J T Conklin (with minor resync against Juergen's changes)
+	+ split-out lib_flash.c from lib_beep.c
+	+ split-out lib_hline.c and lib_vline.c from lib_box.c
+	+ split-out lib_wattron.c, lib_wattroff.c from lib_addch.c
+
+971005
+	> patch by Juergen Pfeifer:
+	+ correct source/target of c++/edit_cfg.sh
+
+971004
+	+ add color, mouse support to kterm terminfo entry.
+	+ modify lib_mouse.c to recognize rxvt, kterm, color_xterm also as
+	  providing "xterm"-style mouse.
+	+ updated rxvt's terminfo description to correspond to 2.21b, with
+	  fixes for the acsc (the box1 capability is incorrect, ech1 does not
+	  work).
+	+ fix logic in parse_entry.c that discarded acsc when 'synthesizing'
+	  an entry from equivalents in XENIX or AIX.  This lets ncurses handle
+	  the distribution copy of rxvt's terminfo.
+	+ modify acsc capability for linux and linux-koi8 terminfo descriptions
+	  (from Pavel Roskin <pavel@absolute.spb.su>).
+	+ corrected definition in curses.h for ACS_LANTERN, which was 'I'
+	  rather than 'i' (see 970802).
+	+ updated terminfo.src with reformatted acsc entries, and repaired the
+	  trashed entries with spurious '\' characters that this exposed.
+	+ add logic to dump_entry.c to reformat acsc entries into canonical
+	  form (sorted, unique mapping).
+	+ add configure script to generate c++/etip.h
+	+ add configure --with-develop option, to enable by default most of the
+	  experimental options (requested by Alexander V. Lukyanov).
+	+ rename 'deinstall' to 'uninstall', following GNU convention
+	  (suggested by Alexander V. Lukyanov).
+	> patches by Alexander V. Lukyanov:
+	+ modify tactics 2 and 5 in onscreen_mvcur(), to allow them on the last
+	  line of the screen, since carriage return will not cause a newline.
+	+ remove clause from PutCharLR() that would try to use
+	  eat_newline_glitch since that apparently does not work on some
+	  terminals (e.g., M$ telnet).
+	+ correct a limit check in scroll_csr_backward()
+	> patches by Juergen Pfeifer:
+	+ adds dummy implementations of methods above() and below() to the
+	  NCursesPanel class.
+	+ fixes missing returncode in NCursesWindow::ripoffline()
+	+ fixes missing returncode in TestApplication::run() in demo.cc
+	+ We should at least give a comment in etip.h why it is currently a
+	  problem to install the C++ binding somewhere
+	+ makes the WINDOW* argument of wenclose() a const.
+	+ modifies several of the routines in lib_adabind.c to use a const
+	  WINDOW* argument.
+
+970927
+	+ add 'deinstall' rules.
+	+ use explicit assignments in configure --without-progs option to
+	  work around autoconf bug which doesn't always set $withval.
+	+ check for ldconfig, don't try to run it if not found.
+	+ implement simple/unoptimized case in lib_doupdate.c to handle
+	  display with magic cookie glitch, tested with ncurses.c program.
+	+ correct missing _tracef in getmouse(), to balance the returnCode
+	  macro.
+	+ simplify show_attr() in ncurses.c using termattrs().
+	> patches by Juergen Pfeifer:
+	+ provides missing inlines for mvw[hv]line in cursesw.h of the C++
+	  binding
+	+ fixes a typo in a comment of frm_driver.c
+	+ Enhances Ada95 Makefiles to fulfill the requirement of GNAT-3.10 that
+	  generics should be compiled.  Proper fixes to the configuration
+	  scripts are also provided.
+
+970920
+	+ several modifications to the configure script (requested by Ward
+	  Horner):
+	  + add configure options --without-progs, to suppress the build of the
+	    utility programs, e.g., for cross-compiling.
+	  + add $(HOSTCCFLAGS) and $(HOSTLDFLAGS) symbols to ncurses
+	    Makefile.in, to simplify setup for cross compiling.
+	  + add logic in configure script to recognize "--target=vxworks", and
+	    generate load/install actions for VxWorks objects.
+	+ move typedef for sigaction_t into SigAction.h to work around problem
+	  generating lint library.
+	+ modify fty_regex.c to reflect renaming of ifdef's for regular
+	  expressions.
+	+ simplify ifdef in lib_setup.c for TIOCGWINSZ since that symbol may
+	  reside in <sys/ioctl.h>.
+	+ merge testcurs.c with version from PDCurses 2.3, clarifying some of
+	  the more obscure tests, which rely upon color.
+	+ use macros getbegyx() and getmaxyx() in newdemo.c and testcurs.c
+	+ modify ncurses.c to use getbegyx() and getmaxyx() macros to cover up
+	  implementation difference wrt SVr4 curses, allow 's' test to work.
+	+ add missing endwin() to testscanw.c program (reported by Fausto
+	  Saporito <fausap@itb.it>).
+	+ fixes/updates for Makefile.glibc and related files under sysdeps
+	  (patch by H.J.Lu).
+	> patches by Juergen Pfeifer:
+	+ add checks for null pointers, especially WINDOW's throughout the
+	  ncurses library.
+	+ solve a problem with wrong calculation of panel overlapping (reported
+	  by Ward Horner):
+	  + make sure that a panel's window isn't a pad.
+	  + do more error checking in module lib_touch.c
+	+ missing files for Ada95 binding from the last patch
+	+ synch. of generated html pages (RCS-Id's were wrong in html files)
+	+ support for Key_Resize in Ada binding
+	+ changed documentation style in ./c++/cursesm.h
+	> patches by Alexander V. Lukyanov:
+	+ undo attempt to do recursive inlining for PutChar(), noting that it
+	  did not improve timing measurably, but inflated the size of
+	  lib_doupdate.o
+
+970913
+	+ modify rain.c to use color.
+	+ correct scroll_csr_backward() to match scroll_csr_forward().
+	+ minor adjustment to llib-lncurses, to work with Solaris 2.5.1
+	+ minor fixes to sysdeps/unix/sysv/linux/configure to reflect renaming
+	  of configure cache variables in 970906.
+	+ correct logic involving changes to O_VISIBLE option in
+	  Synchronize_Options function in frm_driver.c (Tony Hoffmann
+	  <Tony.Hoffmann@hia.nrc.ca>)
+	+ add $(HOSTCC) symbol to ncurses Makefile.in, to simplify setup for
+	  cross compiling (suggested by Chris Johns).
+	+ modify ifdef in lib_setup.c to only include <sys/ioctl.h> if we can
+	  use it to support screen-size calculation (reported by Chris Johns).
+	+ #undef unctrl to avoid symbol conflict in port to RTEMS (reported by
+	  Chris Johns <cjohns@plessey.com.au>)
+	> patches by Juergen Pfeifer:
+	+ simplified, made minor corrections to Ada95 binding to form
+	  fieldtype.
+	+ The C++ binding has been enhanced:
+	  + Improve NCursesWindow class:  added additional methods to cover
+	    more ncurses functionality.  Make refresh() and noutrefresh()
+	    virtual members to allow different implementation in the
+	    NCursesPanel class.
+	  + CAUTION:  changed order of parameters in vline() and hline() of
+	    NCursesWindow class.
+	  + Make refresh() in NCursesPanel non-static, it is now a
+	    reimplementation of refresh() in the base class.  Added
+	    noutrefresh() to NCursesPanel.
+	  + Added NCursesForm and related classes to support libform
+	    functionality.
+	  + Moved most of configuration related stuff from cursesw.h to etip.h
+	  + Added NCursesApplication class to support easy configuration of
+	    menu and forms related attributes as well as ripped of title lines
+	    and Soft-Label-Keys for an application.
+	  + Support of Auto-Cleanup for a menu's fieldlist.
+	  + Change of return type for current_item() and operator[] for menus.
+	  + Enhanced demo.
+	+ Fixed a bug in form/fld_def.c:  take into account that copyarg and
+	  freearg for a fieldtype may be NULL, makearg must not be NULL
+	+ Fixed a bug in form/fld_type.c:  in set_fieldtype_arg() makearg must
+	  not be NULL, copyarg and freearg may be NULL.
+	+ Fixed a bug in form/frm_def.c:  Allow Disconnect_Fields() if it is
+	  already disconnected.
+	+ Enhance form/frm_driver.c:  Allow growth of dynamic fields also on
+	  navigation requests.
+	+ Fixed a bug in form/fty_enum.c:  wrong position of postincrement in
+	  case-insensitiva comparison routine.
+	+ Enhanced form/lib_adabind.c with function _nc_get_field() to get a
+	  forms field by index.
+	+ Enhanced menu/m_adabind.c with function _nc_get_item() to get a menus
+	  item by index.
+	+ Fixed in curses.h.in:  make chtype argument for pechochar() constant.
+	  Mark wbkgdset() as implemented, remove wbkgdset macro, because it was
+	  broken (didn't handle colors correctly).
+	+ Enhanced lib_mouse.c: added _nc_has_mouse() function
+	+ Added _nc_has_mouse() prototype to curses.priv.h
+	+ Modified lib_bkgd.c:  hopefully correct implementation of wbkgdset();
+	  streamlined implementation of wbkgd()
+	+ Modified lib_mvwin.c:  Disable move of a pad.  Implement (costly)
+	  move of subwindows.  Fixed update behavior of movements of regular
+	  windows.
+	+ Fixed lib_pad.c:  make chtype argument of pechochar() const.
+	+ Fixed lib_window.c:  dupwin() is not(!) in every bit a really clone
+	  of the original.  Subwindows become regular windows by doing a
+	  dupwin().
+	+ Improved manpage form_fieldtype.3x
+	> patches by Alexander V. Lukyanov:
+	+ simplify the PutChar() handling of exit_am_mode, because we already
+	  know that auto_right_margin is true.
+	+ add a check in PutChar() for ability to insert to the case of
+	  shifting character to LR corner.
+	+ in terminal initialization by _nc_screen_resume(), make sure that
+	  terminal right margin mode is known.
+	+ move logic that invokes touchline(), or does the equivalent, into
+	  _nc_scroll_window().
+	+ modify scrolling logic use of insert/delete line capability, assuming
+	  that they affect the screen contents only within the current
+	  scrolling region.
+	+ modify rain.c to demonstrate SIGWINCH handler.
+	+ remove logic from getch() that would return an ERR if the application
+	  called getch() when the cursor was at the lower-right corner of the
+	  physical screen, and the terminal does not have insert-character
+	  ability.
+	+ change view.c so that it breaks out of getch() loop if a KEY_RESIZE
+	  is read, and modify logic in getch() so this fix will yield the
+	  desired behavior, i.e., the screen is repainted automatically when
+	  the terminal window is resized.
+
+970906
+	+ add configure option --enable-sigwinch
+	+ modify view.c to test KEY_RESIZE logic, with "-r" option.
+	+ modify testcurs.c to eliminate misleading display wrt cursor type
+	  by testing if the terminal supports cnorm, civis, cvvis.
+	+ several fixes for m68k/NeXT 4.0, to bring cur_term, _nc_curr_line and
+	  _nc_curr_col variables into linked programs:  move these variables,
+	  making new modules lib_cur_term and trace_buf (reported by Francisco
+	  Alberto Tomei Torres <fatomei@sandburg.unm.edu>).
+	> patches by Alexander V. Lukyanov:
+	+ add pseudo-functionkey KEY_RESIZE which is returned by getch() when
+	  the SIGWINCH handler has been called since the last call to
+	  doupdate().
+	+ modify lib_twait.c to hide EINTR only if HIDE_EINTR is defined.
+	+ add SIGWINCH handler to ncurses library which is used if there is no
+	  application SIGWINCH handler in effect when the screen is
+	  initialized.
+	+ make linked list of all SCREEN structures.
+	+ move curses.h include before definition of SCREEN to use types in
+	  that structure.
+	+ correction to ensure that wgetstr uses only a newline to force a
+	  scroll (970831).
+
+970831
+	+ add experimental configure option --enable-safe-sprintf; the normal
+	  mode now allocates a buffer as large as the screen for the
+	  lib_printw.c functions.
+	+ modify wgetch to refresh screen when reading ungetch'd characters,
+	  since the application may require this - SVr4 does this.
+	+ refine treatment of newline in wgetstr to echo only when this would
+	  force the screen to scroll.
+
+970830
+	+ remove override in wgetstr() that forces keypad(), since SVr4 does
+	  not do this.
+	+ correct y-reference for erasure in wgetstr() when a wrap forces a
+	  scroll.
+	+ correct x-position in waddch() after a wrap forces a scroll.
+	+ echo newline in wgetstr(), making testscanw.c scroll properly when
+	  scanw is done.
+	+ modify vwscanw() to avoid potential buffer overflow.
+	+ rewrote lib_printw.c to eliminate fixed-buffer limits.
+	> patches by Alexander V. Lukyanov:
+	+ correct an error in handling cooked mode in wgetch(); processing
+	  was in the wrong order.
+	+ simplified logic in wgetch() that handles backspace, etc., by using
+	  wechochar().
+	+ correct wechochar() so that it interprets the output character as
+	  in waddch().
+	+ modify pechochar() to use prefresh() rather than doupdate(), since
+	  the latter does not guarantee immediate refresh of the pad.
+	+ modify pechochar() so that if called with a non-pad WINDOW, will
+	  invoke wechochar() instead.
+	+ modify fifo indices to allow fifo to be longer than 127 bytes.
+
+970823
+	+ add xterm-8bit to terminfo.src
+	+ moved logic for SP->_fifohold inside check_pending() to make it
+	  work properly when we add calls to that function.
+	+ ensure that bool functions return only TRUE or FALSE, and TRUE/FALSE
+	  are assigned to bool values (patch by H.J.Lu).
+	> patches by Alexander V. Lukyanov:
+	+ several fixes to getch:
+	  1.  Separate cooked and raw keys in fifo
+	  2.  Fix the case of ungetch'ed KEY_MOUSE
+	  3.  wrap the code for hiding EINTR with ifdef HIDE_EINTR
+	  4.  correctly handle input errors (i.e., EINTR) without loss of raw
+	      keys
+	  5.  recognize ESC KEY_LEFT and similar
+	  6.  correctly handle the case of reception of KEY_MOUSE from gpm
+	+ correct off-by-one indexing error in _nc_mouse_parse(), that caused
+	  single mouse events (press/release) to be ignored in favor of
+	  composed events (click).  Improves on a fix from integrating gpm
+	  support in 961229.
+	+ add another call to check_pending, before scrolling, for
+	  line-breakout optimization
+	+ improve hashmap.c by
+	  1.  fixed loop condition in grow_hunks()
+	  2.  not marking lines with offset 0
+	  3.  fixed condition of 'too far' criteria, thus one-line hunks are
+	  ignored and two lines interchanged won't pass.
+	+ rewrote/simplified _nc_scroll_optimize() by separating into two
+	  passes, forward/backward, looking for chunks moving only in the given
+	  direction.
+	+ move logic that emits sgr0 when initializing the screen to
+	  _nc_screen_init(), now invoked from newterm.
+	+ move cursor-movement cleanup from endwin() into _nc_mvcur_wrap()
+	  function and screen cleanup (i.e., color) into _nc_screen_wrap()
+	  function.
+	+ add new functions _nc_screen_init(), _nc_screen_resume() and
+	  _nc_screen_wrap().
+	+ rename _nc_mvcur_scrolln() to _nc_scrolln().
+	+ add a copy of acs_map[] to the SCREEN structure, where it can be
+	  stored/retrieved via set_term().
+	+ move variables _nc_idcok, _nc_idlok, _nc_windows into the SCREEN
+	  structure.
+
+970816
+	+ implement experimental _nc_perform_scroll().
+	+ modify newterm (actually _nc_setupscreen()) to emit an sgr0 when
+	  initializing the screen, as does SVr4 (reported by Alexander V.
+	  Lukyanov).
+	+ added test_progs rule to ncurses/Makefile.
+	+ modify test/configure.in to check if initscr is already in $LIBS
+	  before looking for (n)curses library.
+	+ correct version-number in configure script for OSF1 shared-library
+	  options (patch by Tim Mooney).
+	+ add -DNDEBUG to CPPFLAGS for --enable-assertions (as Juergen
+	  originally patched) since the c++ demo files do not necessarily
+	  include ncurses_cfg.h
+	+ supply default value for --enable-assertions option in configure
+	  script (reported by Kriang Lerdsuwanakij <lerdsuwa@scf-fs.usc.edu>).
+	> patches by Alexander V. Lukyanov:
+	+ correct/simplify logic of werase(), wclrtoeol() and wclrbot().  See
+	  example firstlast.c
+	+ optimize waddch_literal() and waddch_nosync() by factoring out
+	  common subexpressions.
+	+ correct sense of NDEBUG ifdef for CHECK_POSITION macro.
+	+ corrections to render_char(), to make handling of colored blanks
+	  match SVr4 curses, as well as to correct a bug that xor'd space
+	  against the background character.
+	+ replaced hash function with a faster one (timed it)
+	+ rewrote the hashmap algorithm to be one-pass, this avoids multiple
+	  cost_effective() calls on the same lines.
+	+ modified cost_effective() so it is now slightly more precise.
+	> patches for glibc integration (H.J.Lu):
+	+ add modules define_key, keyok, name_match, tries
+	+ add makefile rules for some of the unit tests in ncurses (mvcur,
+	  captoinfo, hardscroll, hashmap).
+	+ update Linux configure-script for wide-character definitions.
+
+970809
+	+ modify _tracebits() to show the character size (e.g., CS8).
+	+ modify tparm() to emit '\200' where the generated string would have a
+	  null (reported by From:  Ian Dall <Ian.Dall@dsto.defence.gov.au> for
+	  terminal type ncr7900).
+	+ modify install process so that ldconfig is not invoked if the
+	  package is built with an install-prefix.
+	+ correct test program for chtype size (reported by Tim Mooney).
+	+ add configure option --disable-scroll-hints, using this to ifdef the
+	  logic that computes indices for _nc_scroll_optimize().
+	+ add module ncurses/softscroll.c, to perform single-stage computation
+	  of scroll indices used in _nc_scroll_optimize().  This is faster than
+	  the existing scrolling algorithm, but tends to make too-small hunks.
+	+ eliminate fixed buffer size in _nc_linedump().
+	+ minor fixes to lib_doupdate.c to add tradeoff between clr_eol (el)
+	  and clr_bol (el1), refine logic in ClrUpdate() and ClrBottom() (patch
+	  by Alexander V. Lukyanov).
+	+ add test/testaddch.c, from a pending patch by Alexander V. Lukyanov.
+	+ correct processing of "configure --enable-assertions" option (patch
+	  by Juergen Pfeifer).
+
+970802
+	+ add '-s' (single-step) option too test/hashtest.c, correct an error
+	  in loop limit for '-f' (footer option), toggle scrollok() when
+	  writing footer to avoid wrap at lower-right corner.
+	+ correct behavior of clrtoeol() immediately after wrapping cursor,
+	  which was not clearing the line at the cursor position (reported by
+	  Liviu Daia <daia@stoilow.imar.ro>).
+	+ corrected mapping for ACS_LANTERN, which was 'I' rather than 'i'
+	  (reported by Klaus Weide <kweide@tezcat.com>).
+	+ many corrections to make progs/capconvert work, as well as make it
+	  reasonably portable and integrated with ncurses 4.1 (reported by Dave
+	  Furstenau <df@ravine.binary.net>).
+
+970726
+	+ add flag SP->_fifohold, corresponding logic to modify the behavior of
+	  the line breakout logic so that if the application does not read
+	  input, refreshes will not be stopped, but only slowed.
+	+ generate slk_attr_off(), slk_attr_on(), slk_attr_set(), vid_attr(),
+	  ifdef'd for wide-character support, since ncurses' WA_xxx attribute
+	  masks are identical with the A_xxx masks.
+	+ modify MKlib_gen.sh to generate ifdef'd functions to support optional
+	  configuration of wide-characters.
+	+ modify tset to behave more like SVr4's tset, which does not modify
+	  the settings of intr, quit or erase unless they are given as command
+	  options (reported by Nelson H. F. Beebe <beebe@math.utah.edu>).
+	+ modify tset to look in /etc/ttys or /etc/ttytype if the configuration
+	  does not have getttynam().
+	+ extend baudrate table in tset.c to match baudrate() function.
+	+ add table entries for B230400 and B460800 to baudrate() function.
+	+ improve breakout logic by allowing it before the first line updated,
+	  which is what SVr4 curses does (patch by Alexander V. Lukyanov).
+	+ correct initialization of vcost in relative_move(), for cursor-down
+	  case (patch by Alexander V. Lukyanov).
+	> nits gleaned from Debian distribution of 1.9.9g-3:
+	+ install symbolic link for intotocap.
+	+ reference libc directly when making shared libraries.
+	+ correct renaming of curs_scr_dmp.3x in man_db.renames.
+	+ guard tgetflag() and other termcap functions against null cur_term
+	  pointer.
+
+970719
+	+ corrected initial state of software echo (error in 970405, reported
+	  by Alexander V. Lukyanov).
+	+ reviewed/added messages to configure script, so that all non-test
+	  options should be accompanied by a message.
+	+ add configure check for long filenames, using this to determine if
+	  it is safe to allow long aliases for terminal descriptions as does
+	  SVr4.
+	+ add configure options for widec (wide character), hashmap (both
+	  experimental).
+	> patch by Alexander V. Lukyanov:
+	+ hashmap.c - improved by heuristic, so that scroll test works much
+	  better when csr is not available.
+	+ hardscroll.c - patched so that it continues to scroll other chunks
+	  after failure to scroll one.
+	+ lib_doupdate.c - _nc_mvcur_scrolln extended to handle more cases; csr
+	  is avoided as it is relative costly.  Fixed wrong coordinates in one
+	  case and wrong string in TRACE.
+	> patch by Juergen Pfeifer:
+	+ modify C++ binding to compile on AIX 4.x with the IBM C-SET++
+	  compiler.
+
+970712
+	+ remove alternate character set from kterm terminfo entry; it uses the
+	  shift-out control for a purpose incompatible with curses, i.e., font
+	  switching.
+	+ disentangle 'xterm' terminfo entry from some derived entries that
+	  should be based on xterm-r6 instead.
+	+ add cbt to xterm-xf86-xv32 terminfo entry; I added the emulation for
+	  XFree86 3.1.2F, but overlooked its use in terminfo then - T.Dickey.
+	+ correct logic in lib_mvcur.c that uses back_tab.
+
+970706
+	+ correct change from 970628 to ClrUpdate() in lib_doupdate.c so that
+	  contents of curscr are saved in newscr before clearing the screen.
+	  This is needed to make repainting work with the present logic of
+	  TransformLine().
+	+ use napms() rather than sleep() in tset.c to avoid interrupting I/O.
+
+970705
+	+ add limit checks to _nc_read_file_entry() to guard against overflow
+	  of buffer when reading incompatible terminfo format, e.g, from OSF/1.
+	+ correct some loop-variable errors in xmc support in lib_doupdate.c
+	+ modify ncurses 'b' test to add gaps, specified by user, to allow
+	  investigation of interaction with xmc (magic cookie) code.
+	+ correct typo in 970524 mods to xmas.c, had omitted empty parameter
+	  list from has_colors(), which gcc ignores, but SVr4 does not
+	  (reported by Larry Virden).
+	+ correct rmso capability in wy50-mc description.
+	+ add configure option "--enable-hard-tabs", renamed TABS_OK ifdef to
+	  USE_HARD_TABS.
+	> patch by Juergen Pfeifer:
+	+ Add bindings for keyok() and define_key() to the Ada95 packages.
+	+ Improve man pages menu_post.3x and menu_format.3x
+	+ Fix the HTML pages in the Ada95/html directory to reflect the above
+	  changes.
+
+970628
+	+ modify change from 970101 to ClrUpdate() in lib_doupdate.c so that
+	  pending changes to both curscr and newscr are flushed properly.
+	  This fixes a case where the first scrolling operation in nvi would
+	  cause the screen to be cleared unnecessarily and repainted before
+	  doing the indexing, i.e., by repeatedly pressing 'j' (reported by
+	  Juergen Pfeifer).
+	+ correct error in trans_string() which added embedded newlines in a
+	  terminfo description to the stored strings.
+	+ remove spurious newlines from sgr in wyse50 (and several other)
+	  terminfo descriptions.
+	+ add configure option for experimental xmc (magic cookie) code,
+	  "--enable-xmc-glitch".  When disabled (the default), attributes that
+	  would store a magic cookie are suppressed in vidputs().  The magic
+	  cookie code is far from workable at this stage; the configuration
+	  option is a stopgap.
+	+ move _nc_initscr() from lib_initscr.c to lib_newterm.c
+	+ correct path for invoking make_keys (a missing "./").
+
+970621
+	+ correct sign-extension problem with "infocmp -e", which corrupted
+	  acsc values computed for linux fallback data.
+	+ correct dependency on ncurses/names.c (a missing "./").
+	+ modify configure script to use '&&' even for cd'ing to existing
+	  directories to work around broken shell interpreters.
+	+ correct a loop-limit in _nc_hash_map() (patch by Alexander V.
+	  Lukyanov).
+
+970615
+	+ restore logic in _nc_scroll_optimize() which marks as touched the
+	  lines in curscr that are shifted.
+	+ add new utility 'make_keys' to compute keys.tries as a table rather
+	  than a series of function calls.
+	+ correct include-dependency for tic.h used by name_match
+	+ removed buffer-allocation for name and description from m_item_new.c,
+	  since this might result in incompatibilities with SVr4.  Also fixed
+	  the corresponding Ada95 binding module (patch by Juergen Pfeifer,
+	  report by Avery Pennarun <apenwarr@foxnet.net>)
+	+ removed the mechanism to timestamp the generated Ada95 sources.  This
+	  resulted always in generating patches for the HTML doc, even when
+	  nothing really changed (patch by Juergen Pfeifer).
+	+ improve man page mitem_new.3x (patch by Juergen Pfeifer).
+
+970614
+	+ remove ech capability from rxvt description because it does not work.
+	+ add missing case logic for infocmp -I option (reported by Lorenzo M.
+	  Catucci <lorenzo@argon.roma2.infn.it>)
+	+ correct old bug in pnoutrefresh() unmasked by fix in 970531; this
+	  caused glitches in the ncurses 'p' test since the area outside the
+	  pad was not compared when setting up indices for _nc_scroll_optimize.
+	+ rewrote tracebits() to workaround misdefinition of TOSTOP on Ultrix
+	  4.4, as well as to eliminate fixed-size buffer (reported by Chris
+	  Tanner <tannerc@aecl.ca>)
+	+ correct prototype for termattrs() as per XPG4 version 2.
+	+ add placeholder prototypes for color_set(), erasewchar(),
+	  term_attrs(), wcolor_set() as per XPG4 version 2.
+	+ correct attribution for progs/progs.priv.h and lib_twait.c
+	+ improve line-breakout logic by checking based on changed lines rather
+	  than total lines (patch by Alexander V. Lukyanov).
+	+ correct loop limits for table-lookup of enumerated value in form
+	  (patch by Juergen Pfeifer).
+	+ improve threshold computation for determining when to call ClrToEOL
+	  (patch by Alexander V. Lukyanov).
+
+970531
+	+ add configure option --disable-database to force the library to
+	  use only the fallback data.
+	+ add configure option --with-fallbacks, to specify list of fallback
+	  terminal descriptions.
+	+ add a symbolic link for ncurses.h during install; too many programs
+	  still assume there's an ncurses.h
+	+ add new terminfo.src entry for xterm-xf86-v33.
+	+ restore terminfo.src entry for emu to using setf/setb, since it is
+	  not, after all, generating ANSI sequences.  Corrected missing comma
+	  that caused setf/setb entries to merge.
+	+ modify mousemask() to use keyok() to enable/disable KEY_MOUSE, so
+	  that applications can disable ncurses' mouse and supply their own
+	  handler.
+	+ add extensions keyok() and define_key().  These are designed to allow
+	  the user's application better control over the use of function keys,
+	  e.g., disabling the ncurses KEY_MOUSE.  (The define_key idea was from
+	  a mailing-list thread started by Kenneth Albanowski
+	  <kjahds@kjahds.com> Nov'1995).
+	+ restore original behavior in ncurses 'g' test, i.e., explicitly
+	  set the keypad mode rather than use the default, since it confuses
+	  people.
+	+ rewrote the newdemo banner so it's readable (reported by Hugh
+	  Daniel).
+	+ tidy up exit from hashtest (reported by Hugh Daniel).
+	+ restore check for ^Q in ncurses 'g' test broken in 970510 (reported
+	  by Hugh Daniel)
+	+ correct tput program, checking return-value of setupterm (patch by
+	  Florian La Roche).
+	+ correct logic in pnoutrefresh() and pechochar() functions (reported
+	  by Kriang Lerdsuwanakij <lerdsuwa@scf.usc.edu>).  The computation
+	  of 'wide' date to eric's #283 (1.9.9), and the pechochar bug to the
+	  original implementation (1.9.6).
+	+ correct typo in vt102-w terminfo.src entry (patch by Robert Wuest
+	  <rwuest@sire.vt.com>)
+	+ move calls of _nc_background() out of various loops, as its return
+	  value will be the same for the whole window being operated on (patch
+	  by J T Conklin).
+	+ add macros getcur[xy] getbeg[xy] getpar[xy], which are defined in
+	  SVr4 headers (patch by J T Conklin <jtc@NetBSD.ORG>)
+	+ modify glibc addon-configure scripts (patch by H.J.Lu).
+	+ correct a bug in hashmap.c: the size used for clearing the hashmap
+	  table was incorrect, causing stack corruption for large values of
+	  LINES, e.g., >MAXLINES/2 (patch by Alexander V. Lukyanov).
+	+ eric's terminfo 9.13.23 & 9.13.24 changes: replaced minitel-2 entry,
+	  added MGR, ansi-nt (note: the changes described for 9.13.24 have not
+	  been applied).
+	> several changes by Juergen Pfeifer:
+	+ correct a missing error-return in form_driver.c when wrapping of a
+	  field is not possible.
+	+ correct logic in form_driver.c for configurations that do not have
+	  memccpy() (reported by Sidik Isani <isani@cfht.hawaii.edu>)
+	+ change several c++ binding functions to inline.
+	+ modify c++ menu binding to inherit from panels, for proper
+	  initialization.
+	+ correct freeing of menu items in c++ binding.
+	+ modify c++ binding to reflect removal of const from user data pointer
+	  in forms/menus libraries.
+
+970524
+	+ add description of xterm-16color.
+	+ modify name of shared-library on *BSD to end with $(REL_VERSION)
+	  rather than $(ABI_VERSION) to match actual convention on FreeBSD
+	  (cf: 960713).
+	+ add OpenBSD to shared-library case, same as NetBSD and FreeBSD
+	  (reported by Hugh Daniel <hugh@rat.toad.com>).
+	+ corrected include-dependency in menu/Makefile so that "make install"
+	  works properly w/o first doing "make".
+	+ add fallback definition for isascii, used in infocmp.
+	+ modify xmas to use color, and to exit right away when a key is
+	  pressed.
+	+ modify gdc so that the scrolled digits function as described (there
+	  was no time delay between the stages, and the digits overwrote the
+	  bounding box without tidying up).
+	+ modify lib_color.c to use setaf/setab only for the ANSI color codes
+	  0 through 7.  Using 16 colors requires setf/setb.
+	+ modify ncurses 'c' test to work with 16 colors, as well as the normal
+	  8 colors.
+	+ remove const qualifier from user data pointer in forms and menus
+	  libraries (patch by Juergen Pfeifer).
+	+ rewrote 'waddchnstr()' to avoid using the _nc_waddch_nosync()
+	  function, thereby not interpreting tabs, etc., as per spec (patch by
+	  Alexander V. Lukyanov).
+
+970517
+	+ suppress check for pre-existing ncurses header if the --prefix
+	  option is specified.
+	+ add configure options "--with-system-type" and
+	  "--with-system-release" to assist in checking the generated
+	  makefiles.
+	+ add configure option "--enable-rpath" to allow installers to specify
+	  that programs linked against shared libraries will have their library
+	  path embedded, allowing installs into nonstandard locations.
+	+ add flags to OSF1 shared-library options to specify version and
+	  symbol file (patch by Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>)
+	+ add missing definition for ABI_VERSION to c++/Makefile.in (reported
+	  by Satoshi Adachi <adachi@wisdom.aa.ap.titech.ac.jp>).
+	+ modify link flags to accommodate HP-UX linker which embeds absolute
+	  pathnames in executables linked against shared libraries (reported by
+	  Jason Evans <jasone@mrc.uidaho.edu>, solved by Alan Shutko
+	  <ats@hubert.wustl.edu>).
+	+ drop unnecessary check for attribute-change in onscreen_mvcur() since
+	  mvcur() is the only caller within the library, and that check in turn
+	  is exercised only from lib_doupdate.c (patch by Alexander V.
+	  Lukyanov).
+	+ add 'blank' parameter to _nc_scroll_window() so _nc_mvcur_scrolln()
+	  can use the background of stdscr as a parameter to that function
+	  (patch by Alexander V. Lukyanov).
+	+ moved _nc_mvcur_scrolln() from lib_mvcur.c to lib_doupdate.c, to use
+	  the latter's internal functions, as well as to eliminate unnecessary
+	  cursor save/restore operations (patch by Alexander V. Lukyanov).
+	+ omit parameter of ClrUpdate(), since it is called only for newscr,
+	  further optimized/reduced by using ClearScreen() and TransformLine()
+	  to get rid of duplicate code (patch by Alexander V. Lukyanov).
+	+ modify scrolling algorithm in _nc_scroll_optimize() to reject hunks
+	  that are smaller than the distance to be moved (patch by Alexander V.
+	  Lukyanov).
+	+ correct a place where the panel library was not ifdef'd in ncurses.c
+	  (Juergen Pfeifer)
+	+ documentation fixes (Juergen Pfeifer)
+
+970515	4.1 release for upload to prep.ai.mit.edu
+	+ re-tag changes since 970505 as 4.1 release.
+
+970510
+	+ modify ncurses 'g' test to allow mouse input
+	+ modify default xterm description to include mouse.
+	+ modify configure script to add -Wwrite-strings if gcc warnings are
+	  enabled while configuring --enable-const (and fixed related
+	  warnings).
+	+ add toggle, status display for keypad mode to ncurses 'g' test to
+	  verify that keypad and scrollok are not inherited from parent window
+	  during a call to newwin.
+	+ correction to MKexpanded.sh to make it work when configure --srcdir
+	  is used (reported by H.J.Lu).
+	+ revise test for bool-type, ensuring that it checks if builtin.h is
+	  available before including it, adding test for sizeof(bool) equal
+	  to sizeof(short), and warning user if the size cannot be determined
+	  (reported by Alexander V. Lukyanov).
+	+ add files to support configuration of ncurses as an add-on library
+	  for GNU libc (patch by H.J.Lu <hjl@lucon.org>)
+
+970506
+	+ correct buffer overrun in lib_traceatr.c
+	+ modify change to lib_vidattr.c to avoid redundant orig_pair.
+	+ turn on 'echo()' in hanoi.c, since it is initially off.
+	+ rename local 'errno' variable in etip.h to avoid conflict with global
+	  (H.J.Lu).
+	+ modify configure script to cache LD, AR, AR_OPTS (patch by H.J.Lu
+	  <hjl@lucon.org>)
+
+970505	4.1 pre-release
+	+ regenerate the misc directory html dumps without the link list, which
+	  is not useful.
+	+ correct dependency in form directory makefile which caused
+	  unnecessary recompiles.
+	+ correct substitution for ABI_VERSION in test-makefile
+	+ modify install rules for shared-library targets to remove the target
+	  before installing, since some install programs do not properly handle
+	  overwrite of symbolic links.
+	+ change order of top-level targets so that 'include' immediate
+	  precedes the 'ncurses' directory, reducing the time between new
+	  headers and new libraries (requested by Larry Virden).
+	+ modify lib_vidattr.c so that colors are turned off only before
+	  modifying other attributes, turned on after others.  This makes the
+	  hanoi.c program display correctly on FreeBSD console.
+	+ modify debug code in panel library to print user-data addresses
+	  rather than the strings which they (may) point to.
+	+ add check to ensure that C++ binding and demo are not built with g++
+	  versions below 2.7, since the binding uses templates.
+	+ modify c++ binding and demo to build and run with SGI's c++ compiler.
+	  (It also compiles with the Sun SparcWorks compiler, but the demo does
+	  not link, due to a vtbl problem).
+	+ corrections to demo.cc, to fix out-of-scope variables (Juergen
+	  Pfeifer).
+
+970503
+	+ correct memory leak in _nc_trace_buf().
+	+ add configure test for regexpr.h, for Unixware 1.x.
+	+ correct missing "./" prefixing names of generated files in ncurses
+	  directory.
+	+ use single-quotes in configure scripts assignments for MK_SHARED_LIB
+	  to workaround shell bug on FreeBSD 2.1.5
+	+ remove tabs from intermediate #define's for GCC_PRINTF, GCC_SCANF
+	  that caused incorrect result in ncurses_cfg.h
+	+ correct initialization in lib_trace.c, which omitted version info.
+	+ remove ech, el1 attributes from cons25w description; they appear to
+	  malfunction in FreeBSD 2.1.5
+	+ correct color attributes in terminfo.src and lib_color.c to match
+	  SVr4 behavior by interchanging codes 1,4, 3,6 in the setf/setb
+	  capabilities.
+	+ use curs_set() rather than checks via tigetstr() for test programs
+	  that hide the cursor: firework, rain, worm.
+	+ ensure that if the terminal lacks change_scroll_region, parm_index
+	  and parm_rindex are used only to scroll the whole screen (patch by
+	  Peter Wemm).
+	+ correct curs_set() logic, which did not return ERR if the requested
+	  attributes did not exist, nor did it assume an unknown initial state
+	  for the cursor (patch by Alexander V. Lukyanov).
+	+ combine IDcTransformLine and NoIDcTransformLine to new TransformLine
+	  function in lib_doupdate.c (patch by Alexander V. Lukyanov).
+	+ correct hashmap.c, which did not update index information (patch by
+	  Alexander V. Lukyanov).
+	+ fixes for C++ binding and demo (see c++/NEWS) (Juergen Pfeifer).
+	+ correct index in lib_instr.c (Juergen Pfeifer).
+	+ correct typo in 970426 patch from Tom's cleanup of lib_overlay.c
+	  (patch by Juergen Pfeifer).
+
+970426
+	+ corrected cost computation in PutRange(), which was using
+	  milliseconds compared to characters by adding two new members to the
+	  SCREEN struct, _hpa_ch_cost and _cup_ch_cost.
+	+ drop ncurses/lib_unctrl.c, add ncurses/MKunctrl.awk to generate a
+	  const array of strings (suggested by Alexander V. Lukyanov).  The
+	  original suggestion in 970118 used a perl script.
+	+ rewrote ncurses 'b' test to better exercise magic-cookie (xmc), as
+	  well as noting the attributes that are not supported by a terminal.
+	+ trace the computation of cost values in lib_mvcur.c
+	+ modify _nc_visbuf() to use octal rather than hex, corrected sign
+	  extension bug in that function that caused buffer overflow.
+	+ modify trace in lib_acs.c to use _nc_visbuf().
+	+ suppress trace within _traceattr2().
+	+ correct logic of _tracechtype2(), which did not account for repeats
+	  or redefinition within an acsc string.
+	+ modify debug-library version baudrate() to use environment variable
+	  $BAUDRATE to override speed computation.  This is needed for
+	  regression testing.
+	+ correct problems shown by "weblint -pedantic".
+	+ update mailing-list information (now ncurses@bsdi.com).
+
+970419
+	+ Improve form_field_validation.3x manpage to better describe the
+	  precision parameter for TYPE_NUMERIC and TYPE_INTEGER.  Provide more
+	  precise information how the range checking can be avoided.  (patch by
+	  Juergen Pfeifer, reported by Bryan Henderson)
+	+ change type of min/max value of form types TYPE_INTEGER to long to
+	  match SVr4 documentation.
+	+ set the form window to stdscr in set_form_win() so that form_win()
+	  won't return null (patch by Juergen Pfeifer, reported by Bryan
+	  Henderson <bryanh@giraffe.netgate.net>).
+
+970412
+	+ corrected ifdef'ing of inline (cf: 970321) for TRACE vs C++.
+	+ corrected toggle_attr_off() macro (patch by Andries Brouwer).
+	+ modify treatment of empty token in $MANPATH to /usr/man (reported by
+	  <Andries.Brouwer@cwi.nl>)
+	+ modify traces that record functions-called so that chtype and attr_t
+	  values are expressed symbolically, to simplify reuse of generated
+	  test-scripts on SVr4 regression testing.
+	+ add new trace functions _traceattr2() and _tracechtype2()
+
+970405
+	+ add configure option --enable-const, to support the use of 'const'
+	  where XSI should have, but did not, specify.  This defines
+	  NCURSES_CONST, which is an empty token otherwise, for strict
+	  compatibility.
+	+ make processing of configure options more verbose by echoing the
+	  --enable/--with values.
+	+ add configure option --enable-big-core
+	+ set initial state of software echo off as per XSI.
+	+ check for C++ builtin.h header
+	+ correct computation of absolute-path for $INSTALL that dropped "-c"
+	  parameter from the expression.
+	+ rename config.h to ncurses_cfg.h to avoid naming-conflict when
+	  ncurses is integrated into larger systems (adapted from diffs by
+	  H.J.Lu for libc).
+	+ correct inequality in lib_doupdate.c that caused a single-char to not
+	  be updated when the char on the right-margin was not blank, idcok()
+	  was true (patch by Alexander V Lukyanov (in 970124), reported
+	  by Kriang Lerdsuwanakij <lerdsuwa@scf-fs.usc.edu> in 970329).
+	+ modify 'clean' rule in include/Makefile so that files created by
+	  configure script are removed in 'distclean' rule instead.
+
+970328
+	+ correct array limit in tparam_internal(), add case to interpret "%x"
+	  (patch by Andreas Schwab)
+	+ rewrote number-parsing in ncurses.c 'd' test; it did not reset the
+	  value properly when non-numeric characters were given (reported by
+	  Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>)
+
+970321
+	+ move definition of __INTERNAL_CAPS_VISIBLE before include for
+	  progs.priv.h (patch by David MacKenzie).

+	  directory to better accommodate a case where installer is configuring
+	  a second copy of ncurses (reported by Klaus Weide
+	  <kweide@tezcat.com>)
+	+ moved the #define for 'inline' as an empty token from the
+	  $(CFLAGS_DEBUG) symbol into config.h, to avoid redefinition warning
+	  (reported by Ward Horner).
+	+ modify test for bool builtin type to use 'unsigned' rather than
+	  'unknown' when cross-compiling (reported by Ward Horner).
+
+970315
+	+ add header dependencies so that "make install.libs" will succeed
+	  even if "make all" is not done first.
+	+ moved some macros from lib_doupdate.c to curses.priv.h to use in
+	  expanded functions with ATAC.
+	+ correct implementation of lib_instr.c; both XSI and SVr4 agree that
+	  the winnstr functions can return more characters than will fit on one
+	  line.
+
+970308
+	+ modify script that generates lib_gen.c to support traces of called &
+	  return.
+	+ add new configure option "--disable-macros", for testing calls within
+	  lib_gen.c
+	+ corrected logic that screens level-checking of called/return traces.
+
+970301
+	+ use new configure macro NC_SUBST to replace AC_PATH_PROG, better
+	  addressing request by Ward Horner.
+	+ check for cross-compiling before trying to invoke the autoconf
+	  AC_FUNC_SETVBUF_REVERSED macro (reported by Ward Horner)
+	+ correct/simplify loop in _nc_visbuf(), 970201 changes omitted
+	  a pointer-increment.
+	+ eliminate obsolete symbol SHARED_ABI from dist.mk (noted by
+	  Florian La Roche).
+
+970215
+	+ add configure option --enable-expanded, together with code that
+	  implements an expanded form of certain complex macros, for testing
+	  with ATAC.
+	+ disable CHECK_POSITION unless --with-assertions is configured
+	  (Alexander V Lukyanov pointed out that this is redundant).
+	+ use keyname() to show traced chtype values where applicable rather
+	  than _tracechar(), which truncates the value to 8-bits.
+	+ minor fixes to TRACE_ICALLS, added T_CREATE, TRACE_CCALLS macros.
+	+ modify makefiles in progs and test directories to avoid using C
+	  preprocessor options on link commands (reported by Ward Horner)
+	+ correct ifdef/include-order for nc_alloc.h vs lib_freeall.c (reported
+	  by Ward Horner)
+	+ modify ifdef's to use configure-defined symbols consistently
+	  (reported by Ward Horner)
+	+ add/use new makefile symbols AR, AR_OPTS and LD to assist in non-UNIX
+	  ports (reported by Ward Horner <whorner@tsi-telsys.com>)
+	+ rename struct try to struct tries, to avoid name conflict with C++
+	  (reported by Gary Johnson).
+	+ modify worm.c to hide cursor while running.
+	+ add -Wcast-qual to gcc warnings, fix accordingly.
+	+ use PutChar rather than PutAttrChar in ClrToEOL to properly handle
+	  wrapping (Alexander V Lukyanov).
+	+ correct spurious echoing of input in hanoi.c from eric's #291 & #292
+	  patches (reported by Vernon C. Hoxie <vern@zebra.alphacdc.com>).
+	+ extend IRIX configuration to IRIX64
+	+ supply missing install.libs rule needed after restructuring
+	  test/Makefile.in
+
+970208
+	+ modify "make mostlyclean" to leave automatically-generated source
+	  in the ncurses directory, for use in cross-compiles.
+	+ autogenerated object-dependencies for test directory
+	+ add configure option --with-rcs-ids
+	+ modify configuration scripts to generate major/minor/patch versions
+	  (suggested by Alexander V Lukyanov).
+	+ supply missing va_end's in lib_scanw.c
+	+ use stream I/O for trace-output, to eliminate fixed-size buffer
+	+ add TRACE_ICALLS definition/support to lib_trace.c
+	+ modify Ada95 binding to work with GNAT 3.09 (Juergen Pfeifer).
+
+970201
+	+ add/modify traces for called/return values to simplify extraction
+	  for test scripts.
+	+ changed _nc_visbuf to quote its result, and to dynamically allocate
+	  the returned buffer.
+	+ invoke ldconfig after installing shared library
+	+ modify install so that overwrite applies to shared library -lcurses
+	  in preference to static library (reported by Zeyd M Ben-Halim 960928).
+	+ correct missing ';' in 961221 mod to overwrite optional use of $(LN_S)
+	  symbol.
+	+ fixes to allow "make install" to work without first doing a "make
+	  all" (suggested by Larry Virden).
+
+970125
+	+ correct order of #ifdef for TABS_OK.
+	+ instrumented toe.c to test memory-leaks.
+	+ correct memory-deallocation in toe.c (patch by Jesse Thilo).
+	+ include <sys/types.h> in configuration test for regex.h (patch by
+	  Andreas Schwab)
+	+ make infocmp recognize -I option, for SVr4 compatibility (reported by
+	  Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>)
+
+970118
+	+ add extension 'use_default_colors()', modified test applications that
+	  use default background (firework, gdc, hanoi, knight, worm) to
+	  demonstrate.
+	+ correct some limit checks in lib_doupdate.c exposed while running
+	  worm.
+	+ use typeCalloc macro for readability.
+	+ add/use definition for CONST to accommodate testing with Solaris
+	  (SVr4) curses, which doesn't use 'const' in its prototypes.
+	+ modify ifdef's in test/hashtest.c and test/view.c to compile with
+	  Solaris curses.
+	+ modify _tracedump() to pad colors & attrs lines to match change
+	  in 970101 showing first/last changes.
+	+ corrected location of terminating null on dynamically allocated forms
+	  fields (patch by Per Foreby).
+
+970111
+	+ added headers to make view.c compile on SCO with the resizeterm()
+	  code (i.e., struct winsize) - though this compiles, I don't have a
+	  suitable test configuration since SIGWINCH doesn't pass my network to
+	  that machine - T.Dickey.
+	+ update test/configure.in to supply some default substitutions.
+	+ modify configure script to add -lncurses after -lgpm to fix problem
+	  linking against static libraries.
+	+ add a missing noraw() to test/ncurses.c (places noted by Jeremy
+	  Buhler)
+	+ add a missing wclear() to test/testcurs.c (patch by Jeremy Buhler
+	  <jbuhler@cs.washington.edu>)
+	+ modify headers to accommodate compilers that don't allow duplicate
+	  "#define" lines for NCURSES_VERSION (reported by Larry W. Virden
+	  <lvirden@cas.org>)
+	+ fix formatting glitch in curs_getch.3x (patch by Jesse Thilo).
+	+ modify lib_doupdate to make el, el1 and ed optimization use the
+	  can_clear_with macro, and change EmitRange to allow leaving cursor at
+	  the middle of interval, rather than always at the end (patch by
+	  Alexander V Lukyanov).  This was originally 960929, resync 970106.
+
+970104
+	+ workaround defect in autoconf 2.12 (which terminates configuration
+	  if no C++ compiler is found) by adding an option --without-cxx.
+	+ modify several man-pages to use tbl, where .nf/.fi was used (reported
+	  by Jesse Thilo).
+	+ correct font-codes in some man-pages (patch by Jesse Thilo
+	  <Jesse.Thilo@pobox.com>)
+	+ use configure script's knowledge of existence of g++ library for the
+	  c++ Makefile (reported by Paul Jackson).
+	+ correct misleading description of --datadir configuration option
+	  (reported by Paul Jackson <pj@sam.engr.sgi.com>)
+
+970101
+	+ several corrections to _nc_mvcur_scrolln(), prompted by a bug report
+	  from Peter Wemm:
+	> the logic for non_dest_scroll_region was interchanged between the
+	  forward & reverse scrolling cases.
+	> multiple returns from the function allowed certain conditions to do
+	  part of an operation before discovering that it couldn't be
+	  completed, returning an error without restoring the cursor.
+	> some returns were ERR, where the function had completed the
+	  operation, because the insert/delete line logic was improperly
+	  tested (this was probably the case Peter saw).
+	> contrary to comments, some scrolling cases were tested after the
+	  insert/delete line method.
+	+ modify _tracedump() to show first/last changes.
+	+ modify param of ClrUpdate() in lib_doupdate.c to 'newscr', fixes
+	  refresh problem (reported by Peter Wemm) that caused nvi to not show
+	  result of ":r !ls" until a ^L was typed.
+
+961229	(internal alpha)
+	+ correct some of the writable-strings warnings (reported by Gary
+	  Johnson <gjohnson@season.com>).  Note that most of the remaining ones
+	  are part of the XSI specification, and can't be "fixed".
+	+ improve include-dependencies in form, menu, panel directories.
+	+ correct logic of delay_output(), which would return early if
+	  there is data on stdin.
+	+ modify interface & logic of _nc_timed_wait() to support 2 file
+	  descriptors, needed for GPM.
+	+ integrate patch by Andrew Kuchling <amk@magnet.com> for GPM (mouse)
+	  support, correcting logic in wgetch() and _nc_mouse_parse() which
+	  prevented patch from working properly -TD
+	+ improve performance of panel algorithm (Juergen Pfeifer 961203).
+	+ strip RCS id's from generated .html files in Ada95 subtree.
+	+ resync with generated .html files (Juergen Pfeifer 961223).
+	+ terminfo.src 10.1.0 (ESR).
+
+961224	4.0 release
+	+ release as 4.0 to accommodate Linux ld.so.1.8.5
+	+ correct syntax/spelling, regenerated .doc files from .html using
+	  lynx 2.5
+	+ refined forms/menus makefiles (Juergen Pfeifer 961223).
+
+961221	- snapshot
+	+ remove logic in read_entry.c that attempts to refine errno by using
+	  'access()' for the directory (from patch by Florian La Roche).
+	+ correct configure test/substitution that inhibits generating
+	  include-path to /usr/include if gcc is used (reported by Florian La
+	  Roche).
+	+ modify setupterm() to allocate new TERMINAL for each call, just as
+	  solaris' curses does (Alexander V Lukyanov 960829).
+	+ corrected memory leaks in read_entry.c
+	+ add configure options --with-dbmalloc, --with-dmalloc, and
+	  --disable-leaks, tested by instrumenting infocmp, ncurses programs.
+	+ move #include's for stdlib.h and string.h to *.priv.h to accommodate
+	  use of dbmalloc.
+	+ modify use of $(LN_S) to follow recommendation in autoconf 2.12,
+	  i.e., set current directory before linking.
+	+ split-out panel.priv.h, improve dependencies for forms, menus
+	  (Juergen Pfeifer 961204).
+	+ modify _nc_freewin() to reset globals curscr/newscr/stdscr when
+	  freeing the corresponding WINDOW (found using Purify).
+	+ modify delwin() to return ERR if the window to be deleted has
+	  subwindows, needed as a side-effect of resizeterm() (found using
+	  Purify).  Tested and found that SVr4 curses behaves this way.
+	+ implement logic for _nc_freeall(), bringing stub up to date.
+
+961215
+	+ modify wbkgd() so that it doesn't set nulls in the rendered text,
+	  even if its argument doesn't specify a character (fixes test case by
+	  Juergen Pfeifer for bug-report).
+	+ set window-attributes in wbkgd(), to simplify comparison against
+	  Solaris curses, which does this.
+
+961214	- snapshot
+	+ replace most constants in ncurses 'o' test by expressions, making it
+	  work with wider range of screen sizes.
+	+ add options to ncurses.c to specify 'e' test softkey format, and the
+	  number of header/footer lines to rip-off.
+	+ add ^R (repaint after resize), ^L (refresh) commands to ncurses 'p'
+	  test.
+	+ add shell-out (!) command to ncurses 'p' test to allow test of
+	  resize between endwin/refresh.
+	+ correct line-wrap case in mvcur() by emitting carriage return,
+	  overlooked in 960928, but needed due to SVr4 compatibility changes to
+	  terminal modes in 960907.
+	+ correct logic in wresize that causes new lines to be allocated,
+	  broken for the special case of increasing rows only in 960907's fix
+	  for subwindows.
+	+ modify configure script to generate $(LDFLAGS) with -L and -l options
+	  in preference to explicit library filenames.  (NOTE: this may
+	  require further amending, since I vaguely recall a dynamic loader
+	  that did not work properly without the full names, but it should be
+	  handled as an exception to the rule, since some linkers do bulk
+	  inclusion of libraries when given the full name - T.Dickey).
+	+ modify configure script to allow user-supplied $CFLAGS to set the
+	  debug-option in all libraries (requested by lots of people) -TD
+	+ use return consistently from main(), rather than exit (reported by
+	  Florian La Roche).
+	+ add --enable-getcap-cache option to configure, normally disabled
+	  (requested by Florian La Roche).
+	+ make configure test for gettimeofday() and possibly -lbsd more
+	  efficient (requested by Florian La Roche <florian@knorke.saar.de>)
+	+ minor adjustments to Ada95 binding (patches by Juergen Pfeifer)
+	+ correct attributes after emitting orig_pair in lib_vidattr.c (patch
+	  by Alexander V Lukyanov).
+
+961208
+	+ corrected README wrt Ada95 (Juergen Pfeifer)
+
+961207	- snapshot
+	+ integrate resizeterm() into doupdate(), so that if screen size
+	  changes between endwin/refresh, ncurses will resize windows to fit
+	  (this needs additional testing with pads and softkeys).
+	+ add, for memory-leak testing, _nc_freeall() entrypoint to free all
+	  data used in ncurses library.
+	+ initialize _nc_idcok, _nc_idlok statically to resolve discrepancy
+	  between initscr() and newwin() initialization (reported by
+	  Alexander V Lukyanov).
+	+ test built VERSION=4.0, SHARED_ABI=4 with Linux ld.so.1.8.5
+	  (set beta versions to those values -- NOTE that subsequent pre-4.0
+	  beta may not be interchangeable).
+	+ modify configure script to work with autoconf 2.12
+
+961130	1.9.9g release
+	+ add copyright notices to configuration scripts (written by Thomas
+	  Dickey).
+
+961127
+	> patch, mostly for panel (Juergen Pfeifer):
+	+ cosmetic improvement for a few routines in the ncurses core library
+	  to avoid warning messages.
+	+ the panel overlap detection was broken
+	+ the panel_window() function was not fool-proof.
+	+ Some inlining...
+	+ Cosmetic changes (also to avoid warning messages when compiling with
+	  -DTRACE).
+
+961126
+	> patch by Juergen Pfeifer:
+	+ eliminates warning messages for the compile of libform.
+	+ inserts Per Foreby's new field type TYPE_IPV4 into libform.
+	+ Updates man page and the Ada95 binding to reflect this.
+	+ Improves inlining in libmenu and libform.
+
+961120
+	+ improve the use of the "const" qualifier in the
+	  panel library (Juergen Pfeifer)
+	+ change set_panel_userptr() and panel_userptr() to use void*
+	  (Juergen Pfeifer)
+
+961119
+	+ change ABI to 3.4
+	+ package with 961119 version of Ada95 binding (fixes for gnat-3.07).
+	  (Juergen Pfeifer)
+	+ correct initialization of the stdscr pseudo panel in panel library
+	  (Juergen Pfeifer)
+	+ use MODULE_ID (rcs keywords) in forms and menus libraries (Juergen
+	  Pfeifer).
+	> patch #324 (ESR):
+	+ typo in curs_termcap man page (reported by Hendrik Reichel
+	  <106065.2344@compuserve.com>)
+	+ change default xterm entry to xterm-r6.
+	+ add entry for color_xterm
+
+961116	- snapshot
+	+ lint found several functions that had only #define implementations
+	  (e.g., attr_off), modified curses.h.in to generate them as per XSI
+	  Curses requirement that every macro be available as a function.
+	+ add check in infocmp.c to guard against string compare of
+	  CANCELLED_STRING values.
+	+ modify firework.c, rain.c to hide cursor while running.
+	+ correct missing va_end in lib_tparm.c
+	+ modify hanoi.c to work on non-color terminals, and to use timing
+	  delays when in autoplay mode.
+	+ correct 'echochar()' to refresh immediately (reported by Adrian
+	  Garside <94ajg2@eng.cam.ac.uk>)
+	> patch #322 (ESR):
+	+ reorganize terminfo.src entries for xterm.
+
+961109	- snapshot
+	+ corrected error in line-breakout logic (lib_doupdate.c)
+	+ modified newdemo to use wgetch(win) rather than getch() to eliminate
+	  a spurious clear-screen.
+	+ corrected ifdef's for 'poll()' configuration.
+	+ added modules to ncurses, form, menu for Ada95 binding (Juergen
+	  Pfeifer).
+	+ modify set_field_buffer() to allow assignment of string longer than
+	  the initial buffer length, and to return the complete string rather
+	  than only the initial size (Juergen Pfeifer and Per Foreby
+	  <perf@efd.lth.se>).
+
+961102	- snapshot
+	+ configure for 'poll()' in preference to 'select()', since older
+	  systems are more likely to have a broken 'select()'.
+	+ modified render_char() to avoid OR'ing colors.
+	+ minor fixes to testcurs.c, newdemo.c test programs: ifdef'd out the
+	  resize test, use wbkgd and corrected box() parameters.
+	+ make flushinp() test work in ncurses.c by using napms() instead of
+	  sleep().
+	+ undo ESR's changes to xterm-x11r6 (it no longer matched the X11R6.1
+	  distribution, as stated)
+	+ terminfo 9.13.18 resync (ESR)
+	+ check for getenv("HOME") returning null (ESR).
+	+ change buffer used to decode xterm-mouse commands to unsigned to
+	  handle displays wider than 128 chars (Juergen Pfeifer).
+	+ correct typo curs_outopts.3x (Juergen Pfeifer).
+	+ correct limit-checking in wenclose() (Juergen Pfeifer).
+	+ correction to Peter Wemm's newwin change (Thomas Fehr
+	  <fehr@suse.de>).
+	+ corrections to logic that combines colors and attributes; they must
+	  not be OR'd (Juergen Pfeifer, extending from report/patch by Rick
+	  Marshall).
+
+961026	- snapshot
+	+ reset flags in 'getwin()' that might cause refresh to attempt to
+	  manipulate the non-existent parent of a window that is read from a
+	  file (lib_screen.c).
+	+ restructure _nc_timed_wait() to log more information, and to try to
+	  recover from badly-behaved 'select()' calls (still testing this).
+	+ move define for GOOD_SELECT into configure script.
+	+ corrected extra '\' character inserted before ',' in comp_scan.c
+	+ corrected expansion of %-format characters in dump_entry.c; some were
+	  rendered as octal constants.
+	+ modify dump_entry.c to make terminfo output more readable and like
+	  SVr4, by using "\s" for spaces (leading/trailing only), "\," for
+	  comma, "\^" and "\:" as well.
+	+ corrected some memory leaks in ncurses.c, and a minor logic error
+	  in the top-level command-parser.
+	+ correction for label format 4 (PC style with info line), a
+	  slk_clear(), slk_restore() sequence didn't redraw the info line
+	  (Juergen Pfeifer).
+	+ modified the slk window (if simulated) to inherit the background and
+	  default character attributes from stdscr (Juergen Pfeifer).
+	+ corrected limit-check in set_top_row (Juergen Pfeifer).
+
+961019	- snapshot
+	+ correct loop-limit in wnoutrefresh(), bug exposed during pipe-testing
+	  had '.lastchar' entry one beyond '._maxx'.
+	+ modify ncurses test-program to work with data piped to it.
+	+ corrected pathname computation in run_tic.sh, removing extra "../"
+	  (reported by Tim Mooney).
+	+ modified configure script to use previous install's location for
+	  curses.h
+	+ added NetBSD and FreeBSD to platforms that use --prefix=/usr as
+	  a default.
+
+961013
+	+ revised xterm terminfo descriptions to reflect the several versions
+	  that are available.
+	+ corrected a pointer reference in dump_entry.c that didn't test if
+	  the pointer was -1.
+
+961005	- snapshot
+	+ correct _nc_mvcur_scrolln for terminals w/o scrolling region.
+	+ add -x option to hashtest to control whether it allows writes to the
+	  lower-right corner.
+	+ ifdef'd (NCURSES_TEST) the logic for _nc_optimize_enable to make it
+	  simpler to construct tests (for double-check of _nc_hash_map tests).
+	+ correct ifdef's for c++ in curses.h
+	+ change default xterm type to xterm-x11r6.
+	+ correct quoting in configure that made man-pages installed with
+	  $datadir instead of actual terminfo path.
+	+ correct whitespace in include/Caps, which caused kf11, clr_eol and
+	  clr_end to be omitted from terminfo.5
+	+ fix memory leaks in delscreen() (adapted from Alexander V Lukyanov).
+	+ improve appearance of marker in multi-selection menu (Juergen
+	  Pfeifer)
+	+ fix behavior for forms with all fields inactive (Juergen Pfeifer)
+	+ document 'field_index()' (Juergen Pfeifer)
+	> patch #321 (ESR):
+	+ add some more XENIX keycap translations to include/Caps.
+	+ modify newwin to set initial state of each line to 'touched'
+	  (from patch by Peter Wemm <peter@spinner.dialix.com>)
+	+ in SET_TTY, replace TCSANOW with TCSADRAIN (Alexander V Lukyanov).
+
+960928	- snapshot
+	+ ifdef'd out _nc_hash_map (still slower)
+	+ add graphic characters to vt52 description.
+	+ use PutAttrChar in ClrToEOL to ensure proper background, position.
+	+ simplify/correct logic in 'mvcur()' that does wrapping; it was
+	  updating the position w/o actually moving the cursor, which broke
+	  relative moves.
+	+ ensure that 'doupdate()' sets the .oldindex values back to a sane
+	  state; this was causing a spurious refresh in ncurses 'r'.
+	+ add logic to configure (from vile) to guard against builders who
+	  don't remove config.cache & config.status when doing new builds -TD
+	+ corrected logic for 'repeat_char' in EmitRange (cf: eric #317), which
+	  did not follow the 2-parameter scheme specified in XSI.
+	+ corrected logic of wrefresh, wnoutrefresh broken in #319, making
+	  clearok work properly (report by Michael Elkins).
+	+ corrected problem with endwin introduced by #314 (removing the

+	+ re-add _nc_hash_map
+	+ modify EmitRange to maintain position as per original design
+	  (patch by A. Lukyanov).
+	+ modify test/ncurses.c and tputs, etc., to allow trace counting

+
+960622	- snapshot

+
+960617
+	+ corrected two logic errors in read_entry.c, write_entry.c (called by

+	+ modified lib_doupdate.c to use lower-level SP's current_attr state
+	  instead of curscr's state, since it is redundant.
+	+ correction to IDcTransformLine logic which controls where InsStr is

+* tic is much better at translating XENIX and AIX termcap entries now.
+* tic can interpret ko capabilities now.

+* revised 'configure' script to produce libraries for normal, debug,
+  profile and shared object models.
+
+### ncurses 1.9.1 -> 1.9.2
+
+* use 'autoconf' to implement 'configure' script.
+* panels support added
+* tic now checks for excessively long termcap entries when doing translation
+* first cut at eliminating namespace pollution.
+
+### ncurses 1.8.9 -> 1.9
+
+* cleanup gcc warnings for the following: use size_t where 'int' is not
+  appropriate, fixed some shadowed variables, change attr_t to compatible with
+  chtype, use attr_t in some places where it was confused with 'int'.
+* use chtype/attr_t casts as appropriate to ensure portability of masking
+  operations.
+* added-back waddchnstr() to lib_addstr.c (it had been deleted).
+* supplied missing prototypes in curses.h
+* include <termcap.h> in lib_termcap.c to ensure that the prototypes
+  are consistent (they weren't).
+* corrected prototype of tputs in <termcap.h>
+* rewrote varargs parsing in lib_tparm.c (to avoid referencing memory
+  that may be out of bounds on the stack) -- Purify found this.
+* ensure that TRACE is defined in lib_trace.c (to solve prototype
+  warnings from gcc).
+* corrected scrolling-region size in 'mvcur_wrap()'
+* more spelling fixes
+* use 'calloc()' to allocate WINDOW struct in lib_newwin.c (Purify).
+* set default value for SP->_ofp in lib_set_term.c (otherwise SunOS dumps
+  core in init_acs()).
+* include <errno.h> in write_entry.c (most "braindead" includes declare errno
+  in that file).
+
+### ncurses 1.8.8 -> 1.8.9
+
+* compile (mostly) clean with gcc 2.5.8 -Wall -Wstrict-prototypes
+  -Wmissing-prototypes -Wconversion and using __attribute__ to flush out
+  non-portable use of "%x" for pointers, or for chtype data (which is declared
+  as a long).
+* modified doupdate to ensure that typahead was turned on before attempting
+  select-call (otherwise, some implementations hang).
+* added trace mask TRACE_FIFO, use this in lib_getch.c to allow finer
+  resolution of traces.
+* improved bounds checking on several critical functions.
+* the data directory has been replaced by the new master terminfo file.
+* -F file-comparison option added to infocmp.
+* compatibility with XSI Curses is now documented in the man bages.
+* wsyncup/wsyncdown functions are reliable now; subwindow code in general
+  is much less flaky.
+* capabilities ~msgr, tilde_glitch, insert_padding, generic_type, no_pad_char,
+  memory_above, memory_below, and hard_copy are now used properly.
+* cursor-movement optimization has been completely rewritten.
+* vertical-movement optimization now uses hardware scrolling, il, dl.
+
+### ncurses 1.8.7 -> 1.8.8
+* untic no longer exists, infocmp replaces it.
+* tic can understand termcap now, especially if it is called captoinfo.
+* The Linux Standard Console terminfo entry is called linux insead of console.
+  It also uses the kernel's new method of changing charsets.
+* initscr() will EXIT upon error (as the docs say) This will mostly happen if
+  you try to run on an undefined terminal.
+* I can get things running on AIX but tic can't compile terminfo. I have to
+  compile entries on another machine. Volunteers to hunt this bug are welcome.
+* wbkgd() and wbkgdset() can be used to set a windows background to color.
+  wclear()/werase() DO NOT use the current attribute to clear the screen.
+  This is the way SVR4 curses works. PDCurses 2.1 is broken in this respect,
+  though PDCurses 2.2 has been fixed.
+* cleaned up the test/ directory.
+* test/worm will segfault after quite a while.
+* many spelling corrections courtesy of Thomas E. Dickey
+
+### ncurses 1.8.6 -> 1.8.7
+* cleaned up programs in test/ directory.
+* fixed wbkgdset() macro.
+* modified getstr() to stop it from advancing cursor in noecho mode.
+* modified linux terminfo entry to work with the latest kernel to get
+  the correct alternate character set.
+* also added a linux-mono entry for those running on monochrome screens.
+* changed initscr() so that it behaves like the man page says it does.
+  this fixes the problem with programs in test/ crashing with SIGSEV if
+  a terminal is undefined.
+* modified addch() to avoid using any term.h #define's
+* removed duplicate tgoto() in lib_tparm.c
+* modified dump_entry.c so that infocmp deals correctly with ',' in acsc
+* modified delwin() to correctly handle deleting subwindows.
+* fixed Makefile.dist to stop installing an empty curses.h
+* fixed a couple of out-of-date notes in man pages.
+
+### ncurses 1.8.5 -> 1.8.6
+* Implemented wbkgd(), bkgd(), bkgdset(), and wbkgdset().
+* The handling of attributes has been improved and now does not turn off color
+  if other attributes are turned off.
+* scrolling code is improved. Scrolling in subwindows is still broken.
+* Fixes to several bugs that manifest them on platforms other than Linux.
+* The default to meta now depends on the status of the terminal when ncurses
+  is started.
+* The interface to the tracing facility has changed.  Instead of the pair of
+  functions traceon() and traceoff(), there is just one function trace() which
+  takes a trace mask argument.  The trace masks, defined in curses.h, are
+  as follows:
+
+	#define TRACE_DISABLE   0x00    /* turn off tracing */
+	#define TRACE_ORDINARY  0x01    /* ordinary trace mode */
+	#define TRACE_CHARPUT   0x02    /* also trace all character outputs */
+	#define TRACE_MAXIMUM   0x0f    /* maximum trace level */
+
+  More trace masks may be added, or these may be changed, in future releases.
+* The pad code has been improved and the pad test code in test/ncurses.c has
+  been improved.
+* The prototype ansi entry has been changed to work with a wider variety
+  of emulators.
+* Fix to the prototype ansi entry that enables it to work with PC emulators
+  that treat trailing ";m" in a highlight sequence as ";0m"; this doesn't
+  break operation with any emulators.
+* There are now working infocmp, captoinfo, tput, and tclear utilities.
+* tic can now compile entries in termcap syntax.
+* Core-dump bug in pnoutrefresh fixed.
+* We now recognize and compile all the nonstandard capabilities in Ross
+  Ridge's mytinfo package (rendering it obsolete).
+* General cleanup and documentation improvements.
+* Fixes and additions to the installation-documentation files.
+* Take cursor to normal mode on endwin.
+
+### ncurses 1.8.4 -> 1.8.5
+* serious bugs in updating screen which caused erratic non-display,
+  fixed.
+* fixed initialization for getch() related variable which cause
+  unpredictable results.
+* fixed another doupdate bug which only appeared if you have
+  parm_char.
+* implemented redrawln() and redrawwin().
+* implemented winsnstr() and related functions.
+* cleaned up insertln() and deleteln() and implemented (w)insdeln().
+* changed Makefile.dist so that installation of man pages will
+  take note of the terminfo directory.
+* fixed Configure (removed the mysterious 'X').
+* Eric S. Raymond fixed the script.* files so that they work with
+  stock awk.
+
+#### ncurses 1.8.3 -> 1.8.4 #### ####
+* fixed bug in refreshing the screen after return from shell_mode.
+  There are still problems but they don't manifest themselves on
+  my machine (Linux 0.99.14f).
+* added wgetnstr() and modified things accordingly.
+* fixed the script.src script.test to work with awk not just gawk.
+* Configure can now take an argument of the target system.
+* added test/ncurses.c which replaces several other programs and
+  performs more testing.
+[Thanks to Eric S Raymond for the last 4]
+* more fixes to lib_overlay.c and added test/over.c to illustrate
+  how it works.
+* fixed ungetch() to take int instead of ch.
+* fixes to cure wgetch() if flushinp() is called.
+
+One note I forgot to mention in 1.8.3 is that tracing is off by
+default starting in the version. If you want tracing output, put
+traceon(); in your code and link with -ldcurses.
+
+#### ncurses 1.8.2 -> ncurses 1.8.3 #### ####
+MAJOR CHANGES:
+1) The order of capabilities has been changed in order to achieve
+binary compatibility with SVR4 terminfo database. This has the
+unfortunate effect of breaking application currently linked with
+ncurses. To ensure correct behavior, recompile all such programs.
+Most programs using color or newer capabilities will break, others
+will probably continue to work ok.
+
+2) Pavel Curtis has renounced his copyright to the public domain.
+This means that his original sources (posted to comp.sources.unix,
+volume 1) are now in the public domain.  The current sources are
+NOT in the public domain, they are copyrighted by me.  I'm
+entertaining ideas on what the new terms ncurses is released under.
+
+3) Eric S. Raymond has supplied a complete set of man pages for
+ncurses in ?roff format. They will eventually replace most of the
+current docs. Both sets are included in this release.
+
+Other changes and notes from 1.8.2 include:
+* SIGSEGV during scrolling no longer occurs.
+* Other problems with scrolling and use of idl have been corrected.
+* lib_getch.c has been re-written and should perform flawlessly.
+  please use test/getch.c and any other programs to test this.
+* ripoffline() is implemented (Thanks to Eric) and slk_ functions
+  changed accordingly.
+* I've added support for terminals that scroll if you write in the
+  bottom-right corner.
+* fixed more bugs in pads code. If anybody has a program that uses
+  pads I'd love a copy.
+* correct handling for terminal with back_color_erase capability
+  (such as Linux console, and most PC terminals)
+* ^Z handling apparently didn't work (I should never trust code
+  sent me to me without extensive testing). It now seems to be
+  fixed. Let me know if you have problems.
+* I've added support for Apollo and NeXT, but it may still be
+  incomplete, especially when dealing with the lack of POSIX
+  features.
+* scrolling should be more efficient on terminals with idl
+  capabilities. Please see src/lib_scroll.c for more notes.
+* The line drawing routines were offset by 1 at both ends. This
+  is now fixed.
+* added a few missing prototypes and macros (e.g. setterm())
+* fixed code in src/lib_overlay.c which used to crash.
+* added a few more programs in test/ The ones from the PDCurses
+  package are useful, especially if you have SVR4 proper. I'm
+  interested in the results you get on such a systems (Eric? ;-).
+  They already exposed certain bugs in ncurses.
+* See src/README for porting notes.
+* The C++ code should really replace ncurses.h instead of working
+  around it. It should avoid name-space clashes with nterm.h (use
+  rows instead of lines, etc.)
+* The C++ should compile ok. I've added explicit rules to the
+  Makefile because no C++ defaults are documented on the suns.
+* The docs say that echo() and nocbreak() are mutually exclusive.
+  At the moment ncurses will switch to cbreak() if the case above
+  occurs. Should it continue to do so? How about echo() and noraw()?
+* PDCurses seem to assume that wclear() will use current attribute
+  when clearing the screen. According to Eric this is not the case
+  with SVR4.
+* I have discovered, to my chagrin, SunOS 4.x (and probably other systems)
+  * doesn't have vsscanf and God knows what else!  I've will do a vsscanf().
+* I've also found out that the src/script.* rely on gawk and will not
+  work with stock awk or even with nawk. Any changes are welcome.
+* Linux is more tolerant of NULL dereferences than most systems. This
+  fact was exposed by hanoi.
+* ncurses still seems inefficient in drawing the screen on a serial
+  link between Linux and suns. The padding may be the culprit.
+* There seems to be one lingering problem with doupdate() after shelling
+  out. Despite the fact the it is sending out the correct information
+  to the terminal, nothing takes effect until you press ^L or another
+  refresh takes place. And yes, output does get flushed.
+
+#### ncurses 1.8.1 -> ncurses 1.8.2 #### Nov 28, 1993 ####
+
+* added support for SVR4 and BSDI's BSD/386.
+* major update and fix to scrolling routine.
+* MORE fixes to stuff in lib_getch.c.
+* cleaned-up configuration options and can now generate
+	Config.* files through an awk script.
+* changed setupterm() so it can be called more than once,
+	add added set_curterm(), del_curterm().
+* a few minor cleanups.
+* added more prototypes in curses.h
+
+#### ncurses 1.8 -> ncurses 1.8.1 #### Nov 4, 1993 ####
+
+* added support for NeXTStep 3.0
+* added termcap emulation (not well tested).
+* more complete C++ interface to ncurses.
+* fixed overlay(), overwrite(), and added copywin().
+* a couple of bug fixes.
+* a few code cleanups.
+
+#### ncurses 0.7.2/0.7.3 -> ncurses 1.8 #### Aug 31, 1993 ####
+
+* The annoying message "can't open file." was due to missing
+  terminfo entry for the used terminal. It has now been
+  replaced by a hopefully more helpful message.
+* Problems with running on serial lines are now fixed.
+* Added configuration files for SunOS, Linux, HP/UX, Ultrix,
+  386bsd/BSDI (if you have others send'em to me)
+* Cleaner Makefile.
+* The documentation in manual.doc is now more uptodate.
+* update optimization and support for hp terminals, and 386bsd
+  console driver(s).
+* mvcur optimization for terminals without cursor addressing
+  (doesn't work on Linux)
+* if cursor moved since last update, getch() will refresh the
+  screen before working.
+* getch() & alarm() can now live together. in 0.7.3 a signal
+  interrupted getch() (bug or feature?) now the getch is
+  restarted.
+* scanw() et all were sick, now fixed.
+* support for 8-bit input (use meta()).
+* added default screen size to all terminfos.
+* added c++ Ncursesw class.
+* several minor bug fixes.
+
+#### ncurses 0.7.2 -> ncurses 0.7.3 #### May 27, 1993 ####
+
+* Config file to cope with different platforms (386BSD, BSDI, Ultrix, SunOS)
+* more fixes to lib_getch.c
+* changes related to Config
+
+#### ncurses 0.7 -> ncurses 0.7.2 #### May 22, 1993 ####
+
+* docs updated slightly (color usage is now documented).
+* yet another fix for getch(), this one fixes problems with ESC being swallowed
+  if another character is typed before the 1 second timeout.
+* Hopefully, addstr() and addch() are 8-bit clean.
+* fixed lib_tparm.c to use stdarg.h (should run on suns now)
+* order of capabilities changed to reflect that specified in SYSV
+  this will allow for binary-compatibility with existing terminfo dbs.
+* added halfdelay()
+* fixed problems with asc_init()
+* added A_PROTECT and A_INVIS
+* cleaned up vidputs()
+* general cleanup of the code
+* more attention to portability to other systems
+* added terminfos for hp70092 (won't work until changes to lib_update.c are
+  made) and 386BSD pcvt drivers.
+
+Thanks to Hellmuth Michaelis for his help.
+optimization code is slated for the next major release, stay tuned!
+
+#### ncurses 0.6/0.61 -> ncurses 0.7 #### April 1, 1993
+Please note that the next release will be called 1.8. If you want to know about
+the rationale drop me a line.
+
+Included are several test programs in test/.
+I've split up the panels library, reversi, tetris, sokoban. They are now
+available separately from netcom.com:pub/zmbenhal/
+
+* color and ACS support is now fully compatible with SYSV at the terminfo
+  level.
+* Capabilities now includes as many SYSV caps I could find.
+* tigetflag,tigetnum,tigetstr functions added.
+* boolnames, boolfnames, boolcodes numnames, numfnames, numcodes,
+  strnames, strfnames, strcodes arrays are now added.
+* keyname() is added.
+* All function keys can be defined in terminfo entries.
+* fixed lin_tparm.c to behave properly.
+* terminfo entries for vt* and xterm are included (improvements are welcome)
+* more automation in handling caps and keys.
+* included fixes from 0.6.1
+* added a few more missing functions.
+* fixed a couple of minor bugs.

+
+1) Included the missing data/console.
+
+2) allow attributes when drawing boxes.
+
+3) corrected usage of win->_delay value.
+
+4) fixed a bug in lib_getch.c. if it didn't recognize a sequence it would
+	simply return the last character in the sequence. The correct
+	behavior is to return the entire sequence one character at a time.
+
+#### ncurses0.5 -> ncurses0.6 #### March 1, 1993 ####
+* removed _numchngd from struct _win_st and made appropriate changes.
+* rewritten kgetch() to remove problems with interaction between alarm and
+  read(). It caused SIGSEGV every now and then.
+* fixed a bug that miscounted the numbers of columns when updating.
+  (in lib_doupdate.c(ClrUpdate() -- iterate to columns not columns-1)
+* fixed a bug that cause the lower-right corner to be incorrect.
+  (in lib_doupdate.c(putChar() -- check against columns not columns-1)
+* made resize() and cleanup() static to lib_newterm.c
+* added notimeout().

+  fixed bug '\n' no causing a LF.
+* fixed bug that reset terminal colors regardless of whether we use color
+  or not.

+See the file INSTALL for instructions on how to build and install ncurses.
+See the file NEWS for a release history and bug-fix notes.
+See the file TO-DO for things that still need doing, including known bugs.

+
+Browse the file doc/html/hackguide.html for a tour of the package internals.
+
+ROADMAP AND PACKAGE OVERVIEW:
+
+You should be reading this file in a directory called:  ncurses-d.d, where d.d
+is the current version number (see the dist.mk file in this directory for
+that).  There should be a number of subdirectories, including `c++', `form',
+`man', `menu', `misc', `ncurses', `panel', `progs', `test', 'tack' and `Ada95'.
+(The 'tack' program may be distributed separately).
+
+A full build/install of this package typically installs several libraries, a
+handful of utilities, and a database hierarchy.  Here is an inventory of the
+pieces:
+
+The libraries are:
+
+	libncurses.a       (normal)
+	libncurses.so      (shared)
+	libncurses_g.a     (debug and trace code enabled)
+	libncurses_p.a     (profiling enabled)
+
+	libpanel.a         (normal)
+	libpanel.so        (shared)
+	libpanel_g.a       (debug and trace code enabled)
+
+	libmenu.a          (normal)
+	libmenu.so         (shared)
+	libmenu_g.a        (debug enabled)
+
+	libform.a          (normal)
+	libform.so         (shared)
+	libform_g.a        (debug enabled)
+
+If you configure using the --enable-widec option, a "w" is appended to the
+library names (e.g., libncursesw.a), and the resulting libraries support
+wide-characters, e.g., via a UTF-8 locale.  The corresponding header files
+are compatible with the non-wide-character configuration; wide-character
+features are provided by ifdef's in the header files.  The wide-character
+library interfaces are not binary-compatible with the non-wide-character
+version.
+
+If you configure using the --enable-reentrant option, a "t" is appended to the
+library names (e.g., libncursest.a) and the resulting libraries have a
+different binary interface which makes the ncurses interface more "opaque".
+
+The ncurses libraries implement the curses API.  The panel, menu and forms
+libraries implement clones of the SVr4 panel, menu and forms APIs.  The source
+code for these lives in the `ncurses', `panel', `menu', and `form' directories
+respectively.
+
+In the `c++' directory, you'll find code that defines an interface to the
+curses, forms, menus and panels library packaged as C++ classes, and a demo program in C++
+to test it.  These class definition modules are not installed by the 'make
+install.libs' rule as libncurses++.
+
+In the `Ada95' directory, you'll find code and documentation for an
+Ada95 binding of the curses API, to be used with the GNAT compiler.
+This binding is built by a normal top-level `make' if configure detects
+an usable version of GNAT (3.11 or above). It is not installed automatically.
+See the Ada95 directory for more build and installation instructions and
+for documentation of the binding.
+
+To do its job, the ncurses code needs your terminal type to be set in the
+environment variable TERM (normally set by your OS; under UNIX, getty(1)
+typically does this, but you can override it in your .profile); and, it needs a
+database of terminal descriptions in which to look up your terminal type's
+capabilities.
+
+In older (V7/BSD) versions of curses, the database was a flat text file,
+/etc/termcap; in newer (USG/USL) versions, the database is a hierarchy of
+fast-loading binary description blocks under /usr/lib/terminfo.  These binary
+blocks are compiled from an improved editable text representation called
+`terminfo' format (documented in man/terminfo.5).  The ncurses library can use
+either /etc/termcap or the compiled binary terminfo blocks, but prefers the
+second form.
+
+In the `misc' directory, there is a text file terminfo.src, in editable
+terminfo format, which can be used to generate the terminfo binaries (that's
+what make install.data does).  If the package was built with the
+--enable-termcap option enabled, and the ncurses library cannot find a terminfo
+description for your terminal, it will fall back to the termcap file supplied
+with your system (which the ncurses package installation leaves strictly
+alone).
+
+The utilities are as follows:
+
+	tic             -- terminfo source to binary compiler
+	infocmp         -- terminfo binary to source decompiler/comparator
+	clear           -- emits clear-screen for current terminal
+	tabs            -- set tabs on a terminal
+	tput            -- shell-script access to terminal capabilities.
+	toe             -- table of entries utility
+	tset            -- terminal-initialization utility
+
+The first two (tic and infocmp) are used for manipulating terminfo
+descriptions; the next two (clear and tput) are for use in shell scripts.  The
+last (tset) is provided for 4.4BSD compatibility.  The source code for all of
+these lives in the `progs' directory.
+
+Detailed documentation for all libraries and utilities can be found in the
+`man' and `doc' directories.  An HTML introduction to ncurses, panels, and
+menus programming lives in the `doc/html' directory.  Manpages in HTML format
+are under `doc/html/man'.
+
+The `test' directory contains programs that can be used to verify or
+demonstrate the functions of the ncurses libraries.  See test/README for
+descriptions of these programs.  Notably, the `ncurses' utility is designed to
+help you systematically exercise the library functions.

+
+This is work in progress, but it is in an state where one can see it
+works at least on the Windows Console.
+
+You should install the MSYS2 package, so that you have a shell environment that
+allows you to run scripts, especially configure, etc.  You can get that
+from
+	https://www.msys2.org/
+
+or the individual packages from
+
+	https://sourceforge.net/projects/msys2/files/
+
+You may also use a hosted MinGW cross-compile toolchain, e.g., on Ubuntu or
+ArchLinux to build the libraries and tools.
+
+To build ncurses for native Windows with support for the new Windows 10 Virtual
+Terminal and PseudoConsole support, you should install at least version 8.0 of
+the mingw-w64-x86_64-headers package as it appears to have support for the
+required Windows SDK level.  Please note that some of the Linux distributions
+are a bit behind with respect to the required MinGW header versions and you may
+not be able to properly build the libraries for current Windows 10 using these
+toolchains.  Although it is a bit slow, MSYS2 on Windows 10 64-Bit is the
+authoritative build environment for the MinGW version of ncurses.
+
+Using MinGW is a pragmatic decision, it is the easiest way to port this
+heavily UNIX based sourcebase to native Windows. The goal is of course
+to provide the includes, libraries and DLLs to be used with the more
+common traditional development environments on Windows, mainly with
+Microsoft Visual Studio.
+
+The TERM environment variable must be set especially to activate the Windows
+console-driver.  The driver checks if TERM is set to "#win32con" (explicit
+use) or if TERM is unset or empty (implicit).
+
+Beginning with build 17763 (Fall 2018 update), Windows 10 supports ANSI escape
+sequences (Virtual Terminal support). If ncurses detects this or a later
+Windows 10 version, the interpretation of the implicit TERM setting (which
+means: TERM is not set or empty) changes. In this case, TERM is to be assumed
+to be "ms-terminal" and ncurses acts using the regular terminfo based driver,
+thus acting like a regular Terminal we all know from UNIX like environments.
+
+This code requires WindowsNT 6.0 or better, which means on the client
+Windows Vista or better, on the server Windows Server 2008 or better.
+
+If running on Windows 10 Build 17763 or later is detected, any program
+spawning a subprocess running a ncurses program should use the new
+PseudoConsole support, which provides what we know as pty from the UNIX
+world also for Windows. Using the CreatePseudoConsole API
+(see https://docs.microsoft.com/en-us/windows/console/createpseudoconsole)
+in the calling process, it is guaranteed that the called ncurses program has
+a console that is required by its implementation, even if the calling program
+is NOT a console program, e.g., MSYS2's own mintty Terminal emulator.
+
+In the current MSYS2/minGW setup, building MinGW shared libraries with
+libtool for ncurses seems to be broken, so I recommend NOT to use libtool.
+
+To build a modern but still small footprint ncurses that provides
+hooks for interop, I recommend using these options:
+
+	--without-libtool
+	--disable-home-terminfo
+	--enable-database
+	--disable-termcap
+	--enable-sp-funcs
+	--enable-term-driver
+	--enable-interop
+
+This is the configuration command line which I am using at the moment
+(assuming environment variable MINGW_ROOT holds the root directory name of
+your MinGW build):
+
+./configure \
+	--prefix=/mingw64 \
+	--without-cxx \
+	--without-ada \
+	--enable-warnings \
+	--enable-assertions \
+	--enable-exp-win32 \
+	--enable-ext-funcs \
+	--disable-home-terminfo \
+	--disable-echo \
+	--disable-getcap \
+	--disable-hard-tabs \
+	--disable-leaks \
+	--disable-macros \
+	--disable-overwrite \
+	--enable-opaque-curses \
+	--enable-opaque-panel \
+	--enable-opaque-menu \
+	--enable-opaque-form \
+	--enable-database \
+	--enable-sp-funcs \
+	--enable-term-driver \
+	--enable-interop \
+	--disable-termcap \
+	--enable-database \
+	--with-progs \
+	--without-libtool \
+	--enable-pc-files \
+	--with-shared \
+	--with-normal \
+	--without-debug \
+	--with-fallbacks=ms-terminal \
+	--without-manpages
+
+Please note that it is also necessary to set this environment variable:
+
+export PATH_SEPARATOR=";"
+
+in order to parse the terminfo paths correctly. Terminfo paths should
+always be separated by a semicolon, even when running under MSYS2.
+
+All the options above are - like the whole Windows support -
+experimental.

+
+You can build ncurses on OS/2 in the EMX environment.  But you must build and
+acquire tools.  Not all of the tools distributed with EMX work properly, and
+some additional ones are required.
+
+First, the configure script distributed with ncurses will not run as-is in EMX.
+You can generate a new one if you have autoconf built for EMX.  You will need
+the EMX development tools, of course.  Get these programs to start:
+
+	GNU m4 program (version 1.4)
+	GNU autoconf (version 2.13).
+	GNU patch (version 2.5)
+
+Apply the autoconf patches from
+
+	https://invisible-island.net/autoconf
+	ftp://ftp.invisible-island.net/autoconf
+
+These are ordered by date:
+
+	autoconf-2.13-20030927.patch.gz
+	autoconf-2.13-20030927-emx.patch.gz
+
+I built my development environment for ncurses using EMX 0.9c at the end of
+1997.  Much of the EMX patch for autoconf was done originally by J.J.G.Ripoll,
+using a similar environment (he prefers using the 'ash' shell).  Newer versions
+may fix these problems:
+
+	+ The pdksh program distributed at Hobbes and Leo (with a 1996 date) is
+	  defective.  It does not process "here documents" correctly (which
+	  renders it useless for running the autoconf script).  I built my own
+	  copy of pdksh 5.2.13, which does have the bug corrected (documented
+	  in the change log for pdksh).
+
+	+ I also built from sources (because the distributed binaries did not
+	  work) the cmp, diff programs.
+
+	  Other required utilities such as ar, cat, chmod, cp, gawk, grep, mv,
+	  ls, rm, mkdir, sed, sort and tr worked.
+
+Once you have autoconf patched and installed, run 'autoconf' from the top-level
+directory of ncurses to generate the EMX-specific configure script.

+
+SHORT-TERM TO-DO ITEMS:
+
+Known Problems:
+
++ libtool does not work with GNAT.
+
++ The screen optimization has been tested only in an ad hoc manner.  We should
+  develop a good set of regression tests to cover lib_doupdate.c and
+  lib_mvcur.c.
+
++ Magic cookie support (for nonzero xmc values) does not work, since the logic
+  does not take into account refresh.  Also, the initial optimize does not
+  adjust the current location when a cookie is emitted.
+
++ Scrolling optimization has holes:  for example, it forces repaints of the
+  screen between calls to refresh().
+
++ SVr4 uses slightly different rules for determining when softkeys are shown.
+  For example, they are initially displayed (before the ncurses 'e' test
+  activates them), and a touchwin can apparently also force them to be
+  displayed.
+
++ The code departs from perfect 8-bit cleanness in one respect; you cannot
+  specify a character \200 as part of a capability string, because the
+  terminfo library interprets \200 as a request to embed NUL (\000) at that
+  point.  This is a legacy terminfo property we can't mess with.
+
++ The window classes defined in the c++ subdirectory need documentation.  Some
+  C++ programmer could earn a lot of good karma by doing this...
+
++ vid_attr() should support the set_a_attributes (sgr1) string, but does not.
+  There appear to be no terminals that require that functionality.
+
++ the configure --disable-ext-funcs option does not work for Ada95 tree.
+
++ the --with-pthread configuration builds for Cygwin, but does not work
+  properly (test/worm.c shows all of the worms in the same location).
+
++ the --enable-rpath configure option builds for the corresponding platforms;
+  however combining it with --with-ticlib and --with-termlib does not always
+  produce libraries that can be run without setting environment variables.
+  Building those with libtool does not work either.  (This is a problem with
+  the BSD platforms).
+
++ more work is needed to make the MinGW port support ordinary terminals.
+
+Portability (or lack thereof):
+
++ Users of older System V UNIXes (but not Solaris, and probably not SVr4) may
+  trip over a known problem with the signal-handling code which causes abrupt
+  termination of ncurses applications following resume from a ^Z suspend (this
+  problem was first seen running lynx).  You will not see this problem if you
+  are using one of the 4.4BSD derivatives like such as, NetBSD, or BSDI, or
+  systems using that convention.  For details, see the analysis in the header
+  comment of ncurses/tty/lib_tstp.c .
+
++ In theory, vwprintw and vwscanf are supposed to use the older varargs.h
+  interface for handling variadic argument lists (and are deprecated by X/Open
+  for that reason).  Many newer systems do no have varargs.h, instead they have
+  only the newer X/Open-standard stdargs.h equivalent.  So these functions use
+  stdargs instead.  This is unlikely to be a problem unless you're building
+  ncurses on a System V old enough to only have varargs.h.  (Solaris 2.5.1 used
+  the stdarg.h binding as well).
+
++ If you're using a system old enough not to have a native vsscanf(3) in its
+  library, vwscanw() will not work.  If you want to fix this, add an
+  implementation to ncurses/vsscanf.c.
+
++ The C++ binding fails to build with a few C++ compilers.
+
++ terminfo.5 does not format with the SunOS (and most other platform's) tbl
+  utility because it relies on a diversion for each table entry.  Get the
+  groff package.
+
+Untested features:
+
++ The code for the HP color model using set_color_pair is untested.
+
++ The code for handling soft labels on a terminal type with built-in support
+  for them (num_labels > 0, label_height, label_width, label_format, label_off,
+  label_on, plab_norm, lab_f*) has not been tested.  The label_format and
+  lab_f* capabilities aren't presently used.
+
+LONGER-TERM TO-DO ITEMS:
+
+1. Extended COSE conformance
+
+There is an XPG4 standard released in 1996 which describes a superset
+of the SVr4 API.  The library is BASE conformant with this standard.
+We would like to make ncurses fully conformant at the EXTENDED level
+supporting internationalization.
+
+2. DOS port
+
+Only a few of the files in the library depend on the terminfo format.
+It should be possible to further kernelize the package, then rewrite
+a small number of core files to produce a functionally-compatible
+port that would do updates to a memory-mapped screen area.  The first
+result of this would be a DOS port.
+
+3. X port
+
+It would be nice if ncurses could recognize when it was running under X and
+maintain its own window.  With this feature, all ncurses programs would
+automatically become X programs.  The challenge is to handle resize events
+properly.
+
+4. Unused capabilities
+
+The currently unused capabilities fall naturally into several groups:
+
+A. Status-line capabilities:
+
+	Booleans: has_status_line, status_line_esc_ok.
+	Numerics: width_status_line.
+	Strings: dis_status_line, from_status_line, to_status_line.
+
+System V Release 1 curses made no use of these at all.  SVr4's use, if
+any, is unknown.  From the AT&T termcap file it looks like curses, in general,
+shouldn't use them; terminal variants with status lines have their line count
+decremented by 1, suggesting that curses is supposed to leave the status line
+alone.
+
+B. Printer capabilities:
+
+	Boolean: col_addr_glitch, cr_cancels_micro_mode, has_print_wheel,
+		row_addr_glitch, semi_auto_right_margin, cpi_changes_res,
+		lpi_changes_res.
+	Numeric: buffer_capacity, dot_horz_spacing, dot_vert_spacing,
+		max_micro_address, max_micro_jump, micro_col_size,
+		micro_line_size, number_of_pins, output_res_char,
+		output_res_line, output_res_horz_inch, print_rate,
+		wide_char_size, bit_image_entwining, bit_image_type.
+	String: down_half_line, form_feed, up_half_line, set_left_margin,
+		set_right_margin, clear_margins, change_char_pitch
+		... set_page_length (all the SVr4 printer caps),
+
+Curses doesn't use these.
+
+C. Printer-control capabilities:
+
+	Boolean: prtr_silent.
+	Strings: print_screen, prtr_on, prtr_off, prtr_non.
+
+Curses doesn't use these.
+
+D. Dialer strings:
+
+	Strings: hangup, dial_phone, quick_dial, tone, pulse, flash_hook,
+		fixed_pause, wait_tone.
+
+Curses doesn't use these.
+
+E. Window and virtual-terminal capabilities:
+
+	Numerics: maximum_windows, virtual_terminal.
+	Strings: req_for_input, create_window, goto_window, set_window.
+
+These seem to be fossils from some AT&T experiments on character-based
+window systems that never escaped the lab.  The virtual_terminal cap had
+something to do with building terminal emulations into tty line disciplines.
+
+F. Unused VDT capabilities:
+
+	Booleans: erase_overstrike, has_meta_key, insert_null_glitch,
+		move_insert, dest_tabs_magic_smso, transparent_underline,
+		needs_xon_xoff, hard_cursor.
+	Numerics: lines_of_memory, buttons.
+	Strings: pkey_key, pkey_local, pkey_xmit, underline_char,
+		enter_xon_mode,	exit_xon_mode, xon_character, xoff_character,
+		display_clock, remove_clock, user[0-5], display_pc_char,
+		enter_scancode_mode, exit_scancode_mode, pc_term_options,
+		scancode_escape, alt_scancode_esc.
+
+These are the potentially important ones for ncurses.  Notes:
+
+	i) ncurses doesn't need move_insert; it never uses cup/hpa/vpa while
+		insert_mode is on.
+
+	ii) We probably don't care about dest_tabs_magic_smso; only
+		Telerays used it and they're all long obsolete.

+dnl -------------------------
+dnl Most "modern" terminal emulators are based to some degree on VT100, and
+dnl should support line-drawing.  Even with Unicode.  There is a problem.
+dnl
+dnl While most of the VT100 graphics characters were incorporated into Unicode,
+dnl all of those were combined into a page of useful graphics characters.
+dnl
+dnl So far, so good.
+dnl
+dnl However, while they are useful, there are other considerations.  CJK
+dnl is (because of poor device resolution) often rendered as double-width
+dnl characters.  So... for these generally-useful characters, what should
+dnl be the width (to make them consistent with adjacent characters)?
+dnl
+dnl The obvious choice would have been to make this locale-dependent, and use
+dnl wcwidth() to tell applications what the actual width is.  That was too
+dnl obvious.  Instead, we have a slew of "ambiguous-width" characters.
+dnl See for example
+dnl		http://www.unicode.org/reports/tr11/tr11-29.html
+dnl		http://www.cl.cam.ac.uk/~mgk25/ucs/scw-proposal.html
+dnl
+dnl The EastAsianWidth-6.2.0.txt file from the Unicode organization lists
+dnl more than 22,000 characters, with 1281 of those as ambiguous-width.  For
+dnl instance, it lists half (44/96) of the Latin-1 characters as
+dnl ambiguous-width.  Also, all of the box-characters at 0x2500 are ambiguous.
+dnl
+dnl What this means for the implementor is that on some systems wcwidth() can
+dnl give bad advice.  On Solaris, some of the ambiguous widths are returned as
+dnl 1 (the Latin-1 characters), while others are returned as 2 (line-drawing
+dnl characters).  These do not necessarily match the behavior of the terminal
+dnl emulator.  xterm, for instance, does an optional startup check to find if
+dnl this problem (or similar) exists with the system's locale tables, rejecting
+dnl them if they are too unreliable.

+dnl -----------------
+dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
+dnl character-strings.
+dnl
+dnl It is ambiguous because the specification accommodated the pre-ANSI
+dnl compilers bundled by more than one vendor in lieu of providing a standard C
+dnl compiler other than by costly add-ons.  Because of this, the specification
+dnl did not take into account the use of const for telling the compiler that
+dnl string literals would be in readonly memory.
+dnl
+dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
+dnl let the compiler decide how to represent Xt's strings which were #define'd.
+dnl That does not solve the problem of using the block of Xt's strings which
+dnl are compiled into the library (and is less efficient than one might want).
+dnl
+dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
+dnl when compiling the library and compiling using the library, to tell the
+dnl compiler that String is const.

+dnl acts as a placeholder.
+dnl
+dnl The ".PHONY" feature was proposed in 2011 here
+dnl     https://www.austingroupbugs.net/view.php?id=523
+dnl and is scheduled for release in P1003.1 Issue 8 (late 2022).
+dnl
+dnl This is not supported by SVr4 make (or SunOS 4, 4.3SD, etc), but works with
+dnl a few others (i.e., GNU make and the non-POSIX "BSD" make):
+dnl
+dnl + This is a GNU make feature (since April 1988, but in turn from binutils,
+dnl   date unspecified).
+dnl
+dnl + It was adopted in NetBSD make in June 1995.
+dnl
+dnl + The other BSD make programs are derived from the NetBSD make (and for
+dnl   that reason are not actually different "implementations").
+dnl
+dnl + Some features of NetBSD make were actually adapted from pmake, which
+dnl   began as a modified GNU make starting in 1993.
+dnl
+dnl + Version 3.8 of the dmake program in January 1992 also implemented this
+dnl   GNU make extension, but is less well known than the BSD make.

+dnl b) ${LOCAL_LDFLAGS2} has the same intention but assumes that the shared
+dnl libraries are compiled in ../../lib
+dnl
+dnl The variable 'cf_cv_do_symlinks' is used to control whether we configure
+dnl to install symbolic links to the rel/abi versions of shared libraries.
+dnl
+dnl The variable 'cf_cv_shlib_version' controls whether we use the rel or abi
+dnl version when making symbolic links.
+dnl
+dnl The variable 'cf_cv_shlib_version_infix' controls whether shared library
+dnl version numbers are infix (ex: libncurses.<ver>.dylib) or postfix
+dnl (ex: libncurses.so.<ver>).

+
+  <h2><a name="h2-overview" id="h2-overview">Overview</a></h2>
+
+  <p>The <span class="main-name">ncurses</span> (new curses)
+  library is a free software emulation of curses in System V
+  Release 4.0 (SVr4), and more. It uses terminfo format, supports
+  pads and color and multiple highlights and forms characters and
+  function-key mapping, and has all the other SVr4-curses
+  enhancements over BSD curses. SVr4 curses became the basis of
+  X/Open Curses.</p>
+
+  <p>In mid-June 1995, the maintainer of 4.4BSD curses declared
+  that he considered 4.4BSD curses obsolete, and encouraged the
+  keepers of <span class="main-name">unix</span> releases such as
+  BSD/OS, FreeBSD and NetBSD to switch over to <span class=
+  "main-name">ncurses</span>.</p>
+
+  <p>Since 1995, <span class="main-name">ncurses</span> has been
+  ported to many systems:</p>
+
+  <ul>
+    <li>It is used in almost every system based on the Linux kernel
+    (aside from some embedded applications).</li>
+
+    <li>It is used as the system curses library on OpenBSD, FreeBSD
+    and MacOS.</li>
+
+    <li>It is used in environments such as Cygwin and MinGW. The
+    first of these was EMX on OS/2 Warp.</li>
+
+    <li>It is used (though usually not as the <em>system</em>
+    curses) on all of the vendor <span class=
+    "main-name">unix</span> systems, e.g., AIX, HP-UX, IRIX64, SCO,
+    Solaris, Tru64.</li>
+
+    <li>It should work readily on any ANSI/POSIX-conforming
+    <span class="main-name">unix</span>.</li>
+  </ul>
+
+  <p>The distribution includes the library and support utilities,
+  including</p>
+
+  <ul>
+    <li><a href="@HOMEPAGE@/man/captoinfo.1m.html"><span class=

+  <p>These notes are for <span class="main-name">ncurses</span>
+  @VERSION@, released <strong>December 31, 2022</strong>.</p>
+
+  <p>This release is designed to be source-compatible with
+  <span class="main-name">ncurses</span> 5.0 through 6.3; providing
+  extensions to the application binary interface (ABI). Although
+  the source can still be configured to support the <span class=
+  "main-name">ncurses</span> 5 ABI, the reason for the release is
+  to reflect improvements to the <span class=
+  "main-name">ncurses</span> 6 ABI and the supporting utility
+  programs.</p>
+
+  <p>There are, of course, numerous other improvements, listed in
+  this announcement.</p>
+
+  <p>The most <a href="#h3-bug-fixes">important
+  bug-fixes/improvements</a> dealt with robustness issues. The
+  release notes also mention some other bug-fixes, but are focused
+  on new features and improvements to existing features since
+  <span class="main-name">ncurses</span> 6.3 release.</p>

+  <h3><a name="h3-bug-fixes" id="h3-bug-fixes">Interesting
+  bug-fixes</a></h3>
+
+  <p>While there were many bugs fixed during development of ncurses
+  6.4, only a few (the reason for this release) were both important
+  and interesting. Most of the bug-fixes were for local issues
+  which did not affect compatibility across releases. Since those
+  are detailed in the <a href=
+  "@HOMEPAGE@/NEWS.html#t20221231">NEWS</a> file no elaboration is
+  needed here.</p>
+
+  <p>The interesting bugs were those dealing with memory leaks and
+  buffer overflows. Although the utilities are designed for
+  <em>text</em> files (which they do properly), some choose to test
+  them with <strong>non-</strong><em>text</em> files.</p>
+
+  <ul>
+    <li>
+      <p>Text files contain no embedded nulls. Also, they end with
+      a newline. Feeding <strong>tic</strong> non-text files
+      exposed a few cases where the program did not check for those
+      issues. As a result, further processing of the input found
+      limit-checks whose assumptions were invalid.</p>
+    </li>
+
+    <li>
+      <p>Fixing the limit-checks (first) found a problem with
+      <strong>tic</strong> managing the list of strings in a
+      terminal description. In merging two terminal descriptions
+      (i.e., the &ldquo;use=&rdquo; feature), <strong>tic</strong>
+      was not allocating a complete copy. A quick repair for that
+      introduced a memory leak.</p>
+    </li>

+
+      <ul>
+        <li>add configure check for <tt>fpathconf</tt></li>
+
+        <li>add configure check for math sine/cosine, needed in

+    </li>
+
+    <li>
+      <p>modify configure macro <tt>CF_BUILD_CC</tt> to check if

+
+    <li>
+      <p>work around <em>musl</em>'s nonstandard use of feature

+  <span class="main-name">ncurses</span></a></h2>
+
+  <p>The <span class="main-name">ncurses</span> package is fully
+  upward-compatible with SVr4 (System V Release 4) curses:</p>
+
+  <ul>
+    <li>
+      <p>All of the SVr4 calls have been implemented (and are
+      documented).</p>
+    </li>
+
+    <li>
+      <p><span class="main-name">ncurses</span> supports all of the
+      for SVr4 curses features including keyboard mapping, color,
+      forms-drawing with ACS characters, and automatic recognition
+      of keypad and function keys.</p>
+    </li>
+
+    <li>
+      <p><span class="main-name">ncurses</span> provides these SVr4
+      add-on libraries (not part of X/Open Curses):</p>
+
+      <ul>
+        <li>
+          <p>the panels library, supporting a stack of windows with
+          backing store.</p>
+        </li>
+
+        <li>
+          <p>the menus library, supporting a uniform but flexible
+          interface for menu programming.</p>
+        </li>
+
+        <li>
+          <p>the form library, supporting data collection through
+          on-screen forms.</p>
+        </li>
+      </ul>
+    </li>
+
+    <li>
+      <p><span class="main-name">ncurses</span>'s terminal database
+      is fully compatible with that used by SVr4 curses.</p>
+
+      <ul>
+        <li>
+          <p><span class="main-name">ncurses</span> supports
+          user-defined capabilities which it can see, but which are
+          hidden from SVr4 curses applications using the
+          <em>same</em> terminal database.</p>
+        </li>
+
+        <li>
+          <p>It can be optionally configured to match the format
+          used in related systems such as AIX and Tru64.</p>
+        </li>
+
+        <li>
+          <p>Alternatively, <span class="main-name">ncurses</span>
+          can be configured to use hashed databases rather than the
+          directory of files used by SVr4 curses.</p>
+        </li>
+      </ul>
+    </li>
+
+    <li>
+      <p>The <span class="main-name">ncurses</span> utilities have
+      options to allow you to filter terminfo entries for use with
+      less capable <em>curses</em>/<em>terminfo</em> versions such
+      as the HP-UX and AIX ports.</p>
+    </li>
+  </ul>
+
+  <p>The <span class="main-name">ncurses</span> package also has
+  many useful extensions over SVr4:</p>
+
+  <ul>
+    <li>
+      <p>The API is 8-bit clean and base-level conformant with the
+      X/OPEN curses specification, XSI curses (that is, it
+      implements all <em>BASE</em> level features, and most
+      <em>EXTENDED</em> features). It includes many function calls
+      not supported under SVr4 curses (but portability of all calls
+      is documented so you can use the SVr4 subset only).</p>
+    </li>
+
+    <li>
+      <p>Unlike SVr3 curses, <span class="main-name">ncurses</span>
+      can write to the rightmost-bottommost corner of the screen if
+      your terminal has an insert-character capability.</p>
+    </li>
+
+    <li>
+      <p>Ada95 and C++ bindings.</p>
+    </li>
+
+    <li>
+      <p>Support for mouse event reporting with X Window xterm and
+      FreeBSD and OS/2 console windows.</p>
+    </li>
+
+    <li>
+      <p>Extended mouse support via Alessandro Rubini's gpm
+      package.</p>
+    </li>
+
+    <li>
+      <p>The function <code>wresize</code> allows you to resize
+      windows, preserving their data.</p>
+    </li>
+
+    <li>
+      <p>The function <code>use_default_colors</code> allows you to
+      use the terminal's default colors for the default color pair,
+      achieving the effect of transparent colors.</p>
+    </li>
+
+    <li>
+      <p>The functions <code>keyok</code> and
+      <code>define_key</code> allow you to better control the use
+      of function keys, e.g., disabling the <span class=
+      "main-name">ncurses</span> KEY_MOUSE, or by defining more
+      than one control sequence to map to a given key code.</p>
+    </li>
+
+    <li>
+      <p>Support for direct-color terminals, such as modern
+      xterm.</p>
+    </li>
+
+    <li>
+      <p>Support for 256-color terminals, such as modern xterm.</p>
+    </li>
+
+    <li>
+      <p>Support for 16-color terminals, such as <em>aixterm</em>
+      and <em>modern xterm</em>.</p>
+    </li>
+
+    <li>
+      <p>Better cursor-movement optimization. The package now
+      features a cursor-local-movement computation more efficient
+      than either BSD's or System V's.</p>
+    </li>
+
+    <li>
+      <p>Super hardware scrolling support. The screen-update code
+      incorporates a novel, simple, and cheap algorithm that
+      enables it to make optimal use of hardware scrolling,
+      line-insertion, and line-deletion for screen-line movements.
+      This algorithm is more powerful than the 4.4BSD curses
+      <code>quickch</code> routine.</p>
+    </li>
+
+    <li>
+      <p>Real support for terminals with the magic-cookie glitch.
+      The screen-update code will refrain from drawing a highlight
+      if the magic- cookie unattributed spaces required just before
+      the beginning and after the end would step on a non-space
+      character. It will automatically shift highlight boundaries
+      when doing so would make it possible to draw the highlight
+      without changing the visual appearance of the screen.</p>
+    </li>
+
+    <li>
+      <p>It is possible to generate the library with a list of
+      pre-loaded fallback entries linked to it so that it can serve
+      those terminal types even when no terminfo tree or termcap
+      file is accessible (this may be useful for support of
+      screen-oriented programs that must run in single-user
+      mode).</p>

+      <p>The <a href="@HOMEPAGE@/man/tic.1m.html"><span class=

+      provided with <span class="main-name">ncurses</span> has the

+    </li>
+
+    <li>
+      <p>The <span class="main-name">ncurses</span> library and
+      utilities will automatically read terminfo entries from
+      $HOME/.terminfo if it exists, and compile to that directory
+      if it exists and the user has no write access to the system
+      directory. This feature makes it easier for users to have
+      personal terminfo entries without giving up access to the
+      system terminfo directory.</p>
+    </li>
+
+    <li>
+      <p>You may specify a path of directories to search for
+      compiled descriptions with the environment variable
+      TERMINFO_DIRS (this generalizes the feature provided by
+      TERMINFO under stock System V.)</p>
+    </li>
+
+    <li>
+      <p>In terminfo source files, use capabilities may refer not
+      just to other entries in the same source file (as in System
+      V) but also to compiled entries in either the system terminfo
+      directory or the user's $HOME/.terminfo directory.</p>
+    </li>
+
+    <li>
+      <p>The table-of-entries utility <a href=
+      "@HOMEPAGE@/man/toe.1m.html"><span class=
+      "part-name">toe</span></a> makes it easy for users to see
+      exactly what terminal types are available on the system.</p>
+    </li>
+
+    <li>
+      <p>The library meets the XSI requirement that every macro
+      entry point has a corresponding function which may be linked
+      (and will be prototype-checked) if the macro definition is
+      disabled with <code>#undef</code>.</p>
+    </li>
+
+    <li>
+      <p>Extensive documentation is provided (see the <em><a href=

+This is a log of changes that the ncurses C++ binding has gone
+through starting with the integration of menu and forms integration
+into the binding.
+
+990731  + Improve support for pads. A viewport window may now be added to
+          a pad. It will then be possible to use a builtin panning mechanism
+          to view the pad.
+
+970908	+ Improve NCursesWindow class: added additional methods to
+	  cover more ncurses functionality. Make refresh() and
+	  noutrefresh() virtual members to allow different implementation
+	  in the NCursesPanel class.
+	+ CAUTION: changed order of parameters in vline() and hline() of
+	  NCursesWindow class.
+	+ Make refresh() in NCursesPanel non-static, it is now a
+	  reimplementation  of refresh() in the base class. Added
+	  noutrefresh() to NCursesPanel.
+	+ Added NCursesForm and related classes to support libform
+	  functionality.
+	+ Moved most of configuration related stuff from cursesw.h to
+	  etip.h
+	+ Added NCursesApplication class to support easy configuration
+	  of menu and forms related attributes as well as ripped of
+	  title lines and Soft-Label-Keys for an application.
+	+ Support of Auto-Cleanup for a menus fieldlist.
+	+ Change of return type for current_item() and operator[] for
+	  menus.
+	+ Enhanced demo.
+970502
+	+ Introduced the THROW and THROWS functions/macros to prepare
+	  a smoother transition to real exception handling.
+	+ Exception classes provided in etip.h
+	+ Added the NCursesMenu class to support libmenu functionality.
+	+ The inheritace relation between NCursesWindow and NCursesColorWindow
+	  was kind of brain damage. Monochrome is a special case of colored, so
+	  the relation should be just the opposite. This would allow all
+	  derived classes like NCursesPanel, NCursesMenu or NCursesForm to
+	  have colors.
+	  To resolve that design flaw I put the color functionality into the
+	  NCursesWindow class and it can be switched on by the static member
+	  useColors(). NCursesColorWindow is still there for compatibility
+	  reasons.

+                  C++ interface to ncurses routines
+-----------------------------------------------------------------------
+
+This directory contains the source code for several C++ classes which
+ease the use of writing ncurses-based programs.  The code was originally
+derived from the libg++ CursesWindow class, but rewritten for ncurses.
+
+The classes simplify the use of window specific functions by
+encapsulating them in the window object.  Function overloading is
+used in order to narrow the interface.  For example, you do not have the
+distinction between `printw' and `mvprintw' anymore.
+
+A second benefit is the removal of all #defines which are included in
+the curses.h file.  This is a steady cause of trouble because many
+common identifiers are used.  Instead now all #defines are inline
+functions, which also allows strict type checking of arguments.
+
+The next enhancement is color support. It was originally provided by a
+derived class.  This caused some trouble if you think about Panels or
+Menus and Forms with colors.  We decided to put color support into the
+base class so that any derived class may use color support also.
+The implementation chosen here is directed to unrestricted use
+of mixes of color and monochrome windows.  The original NCursesColorWindow
+class is maintained for compatibility reasons.
+
+The last point to mention is the support of other packages that are
+distributed with the ncurses package:  the panels library, the menu library
+and the form library.  This support is provided by the NCursesPanel class,
+which is also derived from the NCursesWindow class and the NCursesMenu
+and NCursesForm classes which are derived from NCursesPanel.  This allows
+building interfaces with windows.
+
+Please see the example program for a quick introduction.
+
+Note that at this point, there is no documentation for these classes.
+Hopefully some will be written in the not too distant future.  For now,
+to find out how to use the classes, read the code and the example program.
+
+Suggestions for enhancements and contributions of code (and docs) are
+welcome.  Please let us know which functionality you miss.

+# Configuration subroutine to validate and canonicalize a configuration type.
+# Supply the specified configuration type as an argument.
+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.
+

+# https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
+
+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases
+# that are meaningful with *any* GNU software.
+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.
+
+# The "shellcheck disable" line above the timestamp inhibits complaints
+# about features and limitations of the classic Bourne shell that were
+# superseded or lifted in POSIX.  However, this script identifies a wide
+# variety of pre-POSIX systems that do not have POSIX shells at all, and
+# even some reasonably current systems (Solaris 10 as case-in-point) still
+# have a pre-POSIX /bin/sh.

+Abstract
+
+   This document is a hacker's tour of the ncurses library and utilities.
+   It  discusses  design  philosophy,  implementation  methods,  and  the
+   conventions  used  for  coding  and  documentation.  It is recommended
+   reading  for  anyone  who  is  interested  in  porting,  extending  or
+   improving the package.
+
+Objective of the Package
+
+   The objective of the ncurses package is to provide a free software API
+   for character-cell terminals and terminal emulators with the following
+   characteristics:
+     * Source-compatible    with    historical   curses   implementations
+       (including the original BSD curses and System V curses.
+     * Conformant  with the XSI Curses standard issued as part of XPG4 by
+       X/Open.
+     * High-quality  --  stable and reliable code, wide portability, good
+       packaging, superior documentation.
+     * Featureful  --  should  eliminate  as  much  of  the drudgery of C
+       interface programming as possible, freeing programmers to think at
+       a higher level of design.
+
+   These  objectives  are  in  priority  order.  So,  for example, source
+   compatibility  with  older  version  must  trump  featurefulness -- we
+   cannot  add  features  if  it  means  breaking  the portion of the API
+   corresponding to historical curses versions.
+
+  Why System V Curses?
+
+   We  used System V curses as a model, reverse-engineering their API, in
+   order to fulfill the first two objectives.
+
+   System  V  curses implementations can support BSD curses programs with
+   just a recompilation, so by capturing the System V API we also capture
+   BSD's.
+
+   More  importantly  for  the  future, the XSI Curses standard issued by
+   X/Open  is  explicitly and closely modeled on System V. So conformance
+   with System V took us most of the way to base-level XSI conformance.
+
+  How to Design Extensions
+
+   The  third  objective (standards conformance) requires that it be easy
+   to  condition  source  code  using  ncurses  so  that  the  absence of
+   nonstandard extensions does not break the code.
+
+   Accordingly,  we  have  a  policy of associating with each nonstandard
+   extension  a  feature  macro, so that ncurses client code can use this
+   macro  to  condition  in  or  out  the  code that requires the ncurses
+   extension.
+
+   For  example,  there is a macro NCURSES_MOUSE_VERSION which XSI Curses
+   does  not  define, but which is defined in the ncurses library header.
+   You can use this to condition the calls to the mouse API calls.
+
+Portability and Configuration
+
+   Code  written  for  ncurses may assume an ANSI-standard C compiler and
+   POSIX-compatible  OS  interface.  It may also assume the presence of a
+   System-V-compatible select(2) call.
+
+   We encourage (but do not require) developers to make the code friendly
+   to less-capable UNIX environments wherever possible.
+
+   We  encourage  developers  to  support  OS-specific  optimizations and
+   methods not available under POSIX/ANSI, provided only that:
+     * All  such  code  is properly conditioned so the build process does
+       not attempt to compile it under a plain ANSI/POSIX environment.
+     * Adding    such   implementation   methods   does   not   introduce
+       incompatibilities in the ncurses API between platforms.
+
+   We  use GNU autoconf(1) as a tool to deal with portability issues. The
+   right way to leverage an OS-specific feature is to modify the autoconf
+   specification  files  (configure.in  and  aclocal.m4)  to set up a new
+   feature macro, which you then use to condition your code.
+
+Documentation Conventions
+
+   There  are  three kinds of documentation associated with this package.
+   Each has a different preferred format:
+     * Package-internal files (README, INSTALL, TO-DO etc.)
+     * Manual pages.
+     * Everything else (i.e., narrative documentation).
+
+   Our conventions are simple:
+    1. Maintain package-internal files in plain text. The expected viewer
+       for  them  is  more(1)  or  an editor window; there is no point in
+       elaborate mark-up.
+    2. Mark  up manual pages in the man macros. These have to be viewable
+       through traditional man(1) programs.
+    3. Write everything else in HTML.
+
+   When  in  doubt,  HTMLize  a  master and use lynx(1) to generate plain
+   ASCII (as we do for the announcement document).
+
+   The  reason  for  choosing  HTML  is  that  it is (a) well-adapted for
+   on-line  browsing through viewers that are everywhere; (b) more easily
+   readable  as plain text than most other mark-ups, if you do not have a
+   viewer;  and  (c)  carries  enough information that you can generate a
+   nice-looking  printed  version  from  it.  Also,  of  course,  it make
+   exporting things like the announcement document to WWW pretty trivial.
+
+How to Report Bugs
+
+   The  reporting  address  for  bugs  is  bug-ncurses@gnu.org. This is a
+   majordomo  list;  to join, write to bug-ncurses-request@gnu.org with a
+   message containing the line:
+             subscribe <name>@<host.domain>
+
+   The  ncurses  code is maintained by a small group of volunteers. While
+   we  try  our best to fix bugs promptly, we simply do not have a lot of
+   hours  to  spend  on  elementary  hand-holding. We rely on intelligent
+   cooperation  from  our  users.  If  you  think you have found a bug in
+   ncurses,  there  are some steps you can take before contacting us that
+   will help get the bug fixed quickly.
+
+   In  order  to  use  our bug-fixing time efficiently, we put people who
+   show  us  they  have  taken these steps at the head of our queue. This
+   means that if you do not, you will probably end up at the tail end and
+   have to wait a while.
+    1. Develop a recipe to reproduce the bug.
+       Bugs  we  can reproduce are likely to be fixed very quickly, often
+       within  days.  The most effective single thing you can do to get a
+       quick  fix  is  develop a way we can duplicate the bad behavior --
+       ideally,  by  giving  us source for a small, portable test program
+       that  breaks the library. (Even better is a keystroke recipe using
+       one of the test programs provided with the distribution.)
+    2. Try to reproduce the bug on a different terminal type.
+       In  our experience, most of the behaviors people report as library
+       bugs are actually due to subtle problems in terminal descriptions.
+       This  is  especially  likely  to  be  true  if  you  are  using  a
+       traditional  asynchronous  terminal or PC-based terminal emulator,
+       rather than xterm or a UNIX console entry.
+       It  is  therefore  extremely helpful if you can tell us whether or
+       not  your  problem reproduces on other terminal types. Usually you
+       will  have both a console type and xterm available; please tell us
+       whether or not your bug reproduces on both.
+       If  you  have  xterm  available,  it is also good to collect xterm
+       reports for different window sizes. This is especially true if you
+       normally  use  an unusual xterm window size -- a surprising number
+       of the bugs we have seen are either triggered or masked by these.
+    3. Generate and examine a trace file for the broken behavior.
+       Recompile   your  program  with  the  debugging  versions  of  the
+       libraries.  Insert  a  trace()  call  with  the  argument  set  to
+       TRACE_UPDATE.  (See "Writing Programs with NCURSES" for details on
+       trace  levels.) Reproduce your bug, then look at the trace file to
+       see what the library was actually doing.
+       Another  frequent  cause  of  apparent  bugs is application coding
+       errors  that  cause  the  wrong  things  to  be put on the virtual
+       screen. Looking at the virtual-screen dumps in the trace file will
+       tell  you  immediately if this is happening, and save you from the
+       possible  embarrassment of being told that the bug is in your code
+       and is your problem rather than ours.
+       If  the virtual-screen dumps look correct but the bug persists, it
+       is  possible  to  crank  up  the trace level to give more and more
+       information  about  the  library's  update actions and the control
+       sequences  it  issues  to  perform them. The test directory of the
+       distribution contains a tool for digesting these logs to make them
+       less tedious to wade through.
+       Often  you  will  find terminfo problems at this stage by noticing
+       that  the  escape  sequences  put out for various capabilities are
+       wrong.  If  not,  you  are  likely  to  learn enough to be able to
+       characterize any bug in the screen-update logic quite exactly.
+    4. Report details and symptoms, not just interpretations.
+       If you do the preceding two steps, it is very likely that you will
+       discover the nature of the problem yourself and be able to send us
+       a  fix.  This  will  create happy feelings all around and earn you
+       good karma for the first time you run into a bug you really cannot
+       characterize and fix yourself.
+       If  you  are  still stuck, at least you will know what to tell us.
+       Remember,  we  need  details.  If  you guess about what is safe to
+       leave out, you are too likely to be wrong.
+       If  your  bug  produces a bad update, include a trace file. Try to
+       make  the  trace  at the least voluminous level that pins down the
+       bug.  Logs  that  have been through tracemunch are OK, it does not
+       throw   away  any  information  (actually  they  are  better  than
+       un-munched ones because they are easier to read).
+       If  your bug produces a core-dump, please include a symbolic stack
+       trace generated by gdb(1) or your local equivalent.
+       Tell  us about every terminal on which you have reproduced the bug
+       --  and  every  terminal  on  which  you  cannot. Ideally, send us
+       terminfo sources for all of these (yours might differ from ours).
+       Include  your ncurses version and your OS/machine type, of course!
+       You can find your ncurses version in the curses.h file.
+
+   If  your  problem  smells  like a logic error or in cursor movement or
+   scrolling  or a bad capability, there are a couple of tiny test frames
+   for  the  library  algorithms in the progs directory that may help you
+   isolate  it. These are not part of the normal build, but do have their
+   own make productions.
+
+   The   most  important  of  these  is  mvcur,  a  test  frame  for  the
+   cursor-movement  optimization  code.  With  this  program, you can see
+   directly  what  control sequences will be emitted for any given cursor
+   movement or scroll/insert/delete operations. If you think you have got
+   a  bad  capability  identified, you can disable it and test again. The
+   program is command-driven and has on-line help.
+
+   If  you think the vertical-scroll optimization is broken, or just want
+   to  understand  how it works better, build hashmap and read the header
+   comments  of hardscroll.c and hashmap.c; then try it out. You can also
+   test the hardware-scrolling optimization separately with hardscroll.
+
+A Tour of the Ncurses Library
+
+  Library Overview
+
+   Most  of  the  library is superstructure -- fairly trivial convenience
+   interfaces  to a small set of basic functions and data structures used
+   to  manipulate  the  virtual  screen (in particular, none of this code
+   does  any  I/O  except  through  calls  to  more  fundamental  modules
+   described below). The files
+
+     lib_addch.c    lib_bkgd.c    lib_box.c    lib_chgat.c   lib_clear.c

+
+   are  all  in  this  category.  They  are very unlikely to need change,
+   barring bugs or some fundamental reorganization in the underlying data
+   structures.
+
+   These files are used only for debugging support:
+
+     lib_trace.c     lib_traceatr.c    lib_tracebits.c    lib_tracechr.c
+     lib_tracedmp.c lib_tracemse.c trace_buf.c
+
+   It  is  rather unlikely you will ever need to change these, unless you
+   want to introduce a new debug trace level for some reason.
+
+   There  is  another  group  of  files  that  do direct I/O via tputs(),
+   computations  on  the  terminal  capabilities,  or  queries  to the OS
+   environment,  but  nevertheless have only fairly low complexity. These
+   include:
+
+     lib_acs.c   lib_beep.c   lib_color.c   lib_endwin.c   lib_initscr.c
+     lib_longname.c  lib_newterm.c  lib_options.c lib_termcap.c lib_ti.c
+     lib_tparm.c lib_tputs.c lib_vidattr.c read_entry.c.
+
+   They are likely to need revision only if ncurses is being ported to an
+   environment without an underlying terminfo capability representation.
+
+   These  files  have  serious  hooks  into  the  tty  driver  and signal
+   facilities:
+
+     lib_kernel.c lib_baudrate.c lib_raw.c lib_tstp.c lib_twait.c
+
+   If you run into porting snafus moving the package to another UNIX, the
+   problem  is  likely  to be in one of these files. The file lib_print.c
+   uses sleep(2) and also falls in this category.
+
+   Almost all of the real work is done in the files
+
+     hardscroll.c   hashmap.c   lib_addch.c  lib_doupdate.c  lib_getch.c
+     lib_mouse.c lib_mvcur.c lib_refresh.c lib_setup.c lib_vidattr.c
+
+   Most  of  the  algorithmic  complexity  in  the library lives in these
+   files.  If there is a real bug in ncurses itself, it is probably here.
+   We  will  tour  some  of  these  files in detail below (see The Engine
+   Room).
+
+   Finally,  there  is  a  group  of  files  that is actually most of the
+   terminfo  compiler.  The reason this code lives in the ncurses library
+   is to support fallback to /etc/termcap. These files include
+
+     alloc_entry.c  captoinfo.c  comp_captab.c  comp_error.c comp_hash.c
+     comp_parse.c comp_scan.c parse_entry.c read_termcap.c write_entry.c
+
+   We will discuss these in the compiler tour.
+
+  The Engine Room
+
+    Keyboard Input
+
+   All  ncurses  input  funnels through the function wgetch(), defined in
+   lib_getch.c.  This function is tricky; it has to poll for keyboard and
+   mouse  events and do a running match of incoming input against the set
+   of defined special keys.
+
+   The  central  data  structure  in this module is a FIFO queue, used to
+   match   multiple-character   input   sequences   against   special-key
+   capabilities; also to implement pushback via ungetch().
+
+   The wgetch() code distinguishes between function key sequences and the
+   same  sequences  typed manually by doing a timed wait after each input
+   character  that  could  lead  a  function  key sequence. If the entire
+   sequence  takes  less  than  1  second,  it  is  assumed  to have been
+   generated by a function key press.
+
+   Hackers  bruised  by  previous encounters with variant select(2) calls
+   may  find  the  code  in  lib_twait.c  interesting.  It deals with the
+   problem  that  some  BSD  selects  do  not return a reliable time-left
+   value.  The  function  timed_wait()  effectively  simulates a System V
+   select.
+
+    Mouse Events
+
+   If the mouse interface is active, wgetch() polls for mouse events each
+   call,  before  it  goes  to  the  keyboard  for  input.  It  is  up to
+   lib_mouse.c how the polling is accomplished; it may vary for different
+   devices.
+
+   Under  xterm,  however,  mouse  event  notifications  come  in via the
+   keyboard  input  stream.  They  are  recognized  by  having  the kmous
+   capability  as a prefix. This is kind of klugey, but trying to wire in
+   recognition   of   a  mouse  key  prefix  without  going  through  the
+   function-key  machinery  would be just too painful, and this turns out
+   to  imply having the prefix somewhere in the function-key capabilities
+   at terminal-type initialization.
+
+   This  kluge  only  works  because  kmous  is  not actually used by any
+   historic terminal type or curses implementation we know of. Best guess
+   is  it  is  a relic of some forgotten experiment in-house at Bell Labs
+   that  did  not  leave  any traces in the publicly-distributed System V
+   terminfo  files.  If System V or XPG4 ever gets serious about using it
+   again, this kluge may have to change.
+
+   Here are some more details about mouse event handling:
+
+   The  lib_mouse()  code  is  logically  split  into  a lower level that
+   accepts  event reports in a device-dependent format and an upper level
+   that  parses  mouse  gestures  and  filters events. The mediating data
+   structure is a circular queue of event structures.
+
+   Functionally, the lower level's job is to pick up primitive events and
+   put  them  on  the circular queue. This can happen in one of two ways:
+   either  (a)  _nc_mouse_event()  detects  a  series  of  incoming mouse
+   reports  and queues them, or (b) code in lib_getch.c detects the kmous
+   prefix  in  the  keyboard  input  stream and calls _nc_mouse_inline to
+   queue up a series of adjacent mouse reports.
+
+   In either case, _nc_mouse_parse() should be called after the series is
+   accepted to parse the digested mouse reports (low-level events) into a
+   gesture (a high-level or composite event).
+
+    Output and Screen Updating
+
+   With the single exception of character echoes during a wgetnstr() call
+   (which  simulates  cooked-mode line editing in an ncurses window), the
+   library normally does all its output at refresh time.
+
+   The  main  job  is  to  go  from  the  current state of the screen (as
+   represented  in  the curscr window structure) to the desired new state
+   (as represented in the newscr window structure), while doing as little
+   I/O as possible.
+
+   The  brains  of this operation are the modules hashmap.c, hardscroll.c
+   and  lib_doupdate.c; the latter two use lib_mvcur.c. Essentially, what
+   happens looks like this:
+     * The  hashmap.c  module  tries  to  detect  vertical motion changes
+       between   the  real  and  virtual  screens.  This  information  is
+       represented by the oldindex members in the newscr structure. These
+       are modified by vertical-motion and clear operations, and both are
+       re-initialized  after  each  update.  To  this  change-journalling
+       information,  the  hashmap  code  adds  deductions  made  using  a
+       modified  Heckel  algorithm on hash values generated from the line
+       contents.
+     * The  hardscroll.c  module  computes  an  optimum  set  of  scroll,
+       insertion,  and  deletion operations to make the indices match. It
+       calls _nc_mvcur_scrolln() in lib_mvcur.c to do those motions.
+     * Then  lib_doupdate.c  goes  to work. Its job is to do line-by-line
+       transformations  of curscr lines to newscr lines. Its main tool is
+       the   routine   mvcur()   in   lib_mvcur.c.   This   routine  does
+       cursor-movement  optimization, attempting to get from given screen
+       location  A  to  given  location B in the fewest output characters
+       possible.
+
+   If  you  want to work on screen optimizations, you should use the fact
+   that  (in  the  trace-enabled  version  of  the  library) enabling the
+   TRACE_TIMES  trace  level  causes  a  report  to be emitted after each
+   screen  update  giving  the  elapsed  time  and  a count of characters
+   emitted  during  the  update.  You can use this to tell when an update
+   optimization improves efficiency.
+
+   In  the  trace-enabled  version of the library, it is also possible to
+   disable and re-enable various optimizations at runtime by tweaking the
+   variable  _nc_optimize_enable.  See  the  file include/curses.h.in for
+   mask values, near the end.
+
+The Forms and Menu Libraries
+
+   The  forms  and menu libraries should work reliably in any environment
+   you  can  port ncurses to. The only portability issue anywhere in them
+   is  what  flavor  of  regular expressions the built-in form field type
+   TYPE_REGEXP will recognize.
+
+   The  configuration  code  prefers the POSIX regex facility, modeled on
+   System  V's,  but  will  settle  for  BSD regexps if the former is not
+   available.
+
+   Historical  note:  the  panels code was written primarily to assist in
+   porting  u386mon  2.0 (comp.sources.misc v14i001-4) to systems lacking
+   panels  support; u386mon 2.10 and beyond use it. This version has been
+   slightly cleaned up for ncurses.
+
+A Tour of the Terminfo Compiler
+
+   The ncurses implementation of tic is rather complex internally; it has
+   to  do  a  trying  combination  of missions. This starts with the fact
+   that,  in  addition  to  its normal duty of compiling terminfo sources
+   into  loadable  terminfo binaries, it has to be able to handle termcap
+   syntax and compile that too into terminfo entries.
+
+   The  implementation  therefore  starts  with a table-driven, dual-mode
+   lexical analyzer (in comp_scan.c). The lexer chooses its mode (termcap
+   or terminfo) based on the first "," or ":" it finds in each entry. The
+   lexer  does  all  the work of recognizing capability names and values;
+   the  grammar above it is trivial, just "parse entries till you run out
+   of file".
+
+  Translation of Non-use Capabilities
+
+   Translation   of  most  things  besides  use  capabilities  is  pretty
+   straightforward.   The   lexical   analyzer's   tokenizer  hands  each
+   capability  name  to a hash function, which drives a table lookup. The
+   table entry yields an index which is used to look up the token type in
+   another table, and controls interpretation of the value.
+
+   One  possibly  interesting aspect of the implementation is the way the
+   compiler  tables  are  initialized.  All  the  tables are generated by
+   various  awk/sed/sh  scripts  from  a master table include/Caps; these
+   scripts  actually  write  C  initializers  which  are  linked  to  the
+   compiler. Furthermore, the hash table is generated in the same way, so
+   it  doesn't  have  to  be  generated at compiler startup time (another
+   benefit  of  this  organization  is  that  the  hash  table  can be in
+   shareable text space).
+
+   Thus, adding a new capability is usually pretty trivial, just a matter
+   of  adding one line to the include/Caps file. We will have more to say
+   about this in the section on Source-Form Translation.
+
+  Use Capability Resolution
+
+   The  background  problem  that  makes tic tricky is not the capability
+   translation  itself,  it  is the resolution of use capabilities. Older
+   versions would not handle forward use references for this reason (that
+   is, a using terminal always had to follow its use target in the source
+   file).  By  doing  this,  they  got  away with a simple implementation
+   tactic;  compile  everything  as  it  blows by, then resolve uses from
+   compiled entries.
+
+   This  will  not  do  for  ncurses.  The problem is that that the whole
+   compilation  process  has  to  be embeddable in the ncurses library so
+   that it can be called by the startup code to translate termcap entries
+   on  the  fly.  The  embedded  version  cannot go promiscuously writing
+   everything  it  translates  out  to  disk  --  for  one thing, it will
+   typically be running with non-root permissions.
+
+   So  our  tic  is  designed  to  parse  an  entire terminfo file into a
+   doubly-linked  circular  list of entry structures in-core, and then do
+   use  resolution  in-memory  before writing everything out. This design
+   has other advantages: it makes forward and back use-references equally
+   easy  (so  we get the latter for free), and it makes checking for name
+   collisions before they are written out easy to do.
+
+   And   this  is  exactly  how  the  embedded  version  works.  But  the
+   stand-alone  user-accessible  version  of  tic  partly  reverts to the
+   historical strategy; it writes to disk (not keeping in core) any entry
+   with no use references.
+
+   This  is  strictly  a  core-economy  kluge,  implemented  because  the
+   terminfo  master file is large enough that some core-poor systems swap
+   like crazy when you compile it all in memory...there have been reports
+   of  this process taking three hours, rather than the twenty seconds or
+   less typical on the author's development box.
+
+   So. The executable tic passes the entry-parser a hook that immediately
+   writes  out  the  referenced  entry if it has no use capabilities. The
+   compiler  main loop refrains from adding the entry to the in-core list
+   when  this hook fires. If some other entry later needs to reference an
+   entry  that  got  written immediately, that is OK; the resolution code
+   will fetch it off disk when it cannot find it in core.
+
+   Name  collisions  will  still  be  detected,  just not as cleanly. The
+   write_entry()   code   complains  before  overwriting  an  entry  that
+   postdates  the time of tic's first call to write_entry(), Thus it will
+   complain  about overwriting entries newly made during the tic run, but
+   not about overwriting ones that predate it.
+
+  Source-Form Translation
+
+   Another use of tic is to do source translation between various termcap
+   and terminfo formats. There are more variants out there than you might
+   think; the ones we know about are described in the captoinfo(1) manual
+   page.
+
+   The  translation output code (dump_entry() in ncurses/dump_entry.c) is
+   shared  with  the  infocmp(1)  utility.  It  takes  the  same internal
+   representation  used  to  generate  the  binary  form  and dumps it to
+   standard output in a specified format.
+
+   The  include/Caps  file  has  a header comment describing ways you can
+   specify  source  translations  for  nonstandard  capabilities  just by
+   altering  the  master  table.  It  is  possible  to  set up capability
+   aliasing  or  tell  the  compiler  to  plain ignore a given capability
+   without writing any C code at all.
+
+   For  circumstances where you need to do algorithmic translation, there
+   are  functions  in  parse_entry.c called after the parse of each entry
+   that are specifically intended to encapsulate such translations. This,
+   for  example,  is  where  the AIX box1 capability get translated to an
+   acsc string.
+
+Other Utilities
+
+   The  infocmp  utility  is just a wrapper around the same entry-dumping
+   code  used  by tic for source translation. Perhaps the one interesting
+   aspect  of  the  code  is the use of a predicate function passed in to
+   dump_entry()  to  control  which  capabilities  are  dumped.  This  is
+   necessary in order to handle both the ordinary De-compilation case and
+   entry difference reporting.
+
+   The  tput  and  clear  utilities  just  do an entry load followed by a
+   tputs() of a selected capability.
+
+Style Tips for Developers
+
+   See   the  TO-DO  file  in  the  top-level  directory  of  the  source
+   distribution for additions that would be particularly useful.
+
+   The  prefix  _nc_  should be used on library public functions that are
+   not  part  of  the  curses  API  in  order to prevent pollution of the
+   application  namespace.  If  you have to add to or modify the function
+   prototypes  in curses.h.in, read ncurses/MKlib_gen.sh first so you can
+   avoid  breaking XSI conformance. Please join the ncurses mailing list.
+   See  the INSTALL file in the top level of the distribution for details
+   on the list.
+
+   Look  for  the  string  FIXME  in  source  files to tag minor bugs and
+   potential problems that could use fixing.
+
+   Do  not try to auto-detect OS features in the main body of the C code.
+   That is the job of the configuration system.
+
+   To hold down complexity, do make your code data-driven. Especially, if
+   you  can drive logic from a table filtered out of include/Caps, do it.
+   If  you  find  you  need  to augment the data in that file in order to
+   generate  the proper table, that is still preferable to ad-hoc code --
+   that is why the fifth field (flags) is there.
+
+   Have fun!
+
+Porting Hints
+
+   The  following  notes  are intended to be a first step towards DOS and
+   Macintosh ports of the ncurses libraries.
+
+   The  following library modules are "pure curses"; they operate only on
+   the  curses  internal  structures,  do all output through other curses
+   calls  (not  including  tputs()  and putp()) and do not call any other
+   UNIX  routines  such  as  signal(2)  or  the stdio library. Thus, they
+   should not need to be modified for single-terminal ports.
+
+     lib_addch.c    lib_addstr.c    lib_bkgd.c   lib_box.c   lib_clear.c
+     lib_clrbot.c   lib_clreol.c  lib_delch.c  lib_delwin.c  lib_erase.c
+     lib_inchstr.c  lib_insch.c  lib_insdel.c lib_insstr.c lib_keyname.c
+     lib_move.c   lib_mvwin.c   lib_newwin.c   lib_overlay.c   lib_pad.c
+     lib_printw.c  lib_refresh.c  lib_scanw.c  lib_scroll.c lib_scrreg.c
+     lib_set_term.c  lib_touch.c  lib_tparm.c  lib_tputs.c  lib_unctrl.c
+     lib_window.c panel.c
+
+   This module is pure curses, but calls outstr():
+
+     lib_getstr.c
+
+   These  modules  are  pure  curses,  except  that  they use tputs() and
+   putp():
+
+     lib_beep.c   lib_color.c   lib_endwin.c   lib_options.c   lib_slk.c
+     lib_vidattr.c
+
+   This modules assist in POSIX emulation on non-POSIX systems:
+
+   sigaction.c
+          signal calls
+
+   The    following   source   files   will   not   be   needed   for   a
+   single-terminal-type port.
+
+     alloc_entry.c   captoinfo.c   clear.c   comp_captab.c  comp_error.c
+     comp_hash.c   comp_main.c   comp_parse.c  comp_scan.c  dump_entry.c
+     infocmp.c parse_entry.c read_entry.c tput.c write_entry.c
+
+   The  following  modules will use open()/read()/write()/close()/lseek()
+   on files, but no other OS calls.
+
+   lib_screen.c
+          used to read/write screen dumps
+
+   lib_trace.c
+          used to write trace data to the logfile
+
+   Modules that would have to be modified for a port start here:
+
+   The  following  modules  are  "pure  curses"  but  contain assumptions
+   inappropriate for a memory-mapped port.
+
+   lib_longname.c
+          assumes there may be multiple terminals
+
+   lib_acs.c
+          assumes acs_map as a double indirection
+
+   lib_mvcur.c
+          assumes cursor moves have variable cost
+
+   lib_termcap.c
+          assumes there may be multiple terminals
+
+   lib_ti.c
+          assumes there may be multiple terminals
+
+   The following modules use UNIX-specific calls:
+
+   lib_doupdate.c
+          input checking
+
+   lib_getch.c
+          read()
+
+   lib_initscr.c
+          getenv()
+
+   lib_newterm.c
+   lib_baudrate.c
+   lib_kernel.c
+          various tty-manipulation and system calls
+
+   lib_raw.c
+          various tty-manipulation calls
+
+   lib_setup.c
+          various tty-manipulation calls
+
+   lib_restart.c
+          various tty-manipulation calls
+
+   lib_tstp.c
+          signal-manipulation calls
+
+   lib_twait.c
+          gettimeofday(), select().

+  <h1>Ada95 Binding for ncurses</h1>
+
+  <p>by J&uuml;rgen Pfeifer.</p>
+  <hr>
+
+  <h2>General Remarks</h2>
+
+  <ul>
+    <li>This document describes Version 01.00 of the binding.</li>
+
+    <li>The functionality is modeled to be compatible with the
+    ncurses package, a clone of the SVr4 curses model.<br>
+    I did the development on an Intel box running the latest stable
+    release of <a href="http://www.linux.org">Linux</a>, ncurses
+    and the most recent released <a href="https://ftp.gnu.org/gnu/gcc/">GNU 
+    Ada Translator</a> gnat versions. For any older versions of
+    ncurses and gnat it is not guaranteed to work.</li>
+
+    <li>You must have the m4 macroprocessor to build this package.
+    If you don't have this program, you can get the FSF version
+    <a href="https://ftp.gnu.org/pub/gnu/">here</a>.</li>
+
+    <li>Ada programs are supposed to be readable. One of my
+    favorite methods to make code readable is to use expressive
+    names for the identifiers. You can find a list of a mapping of
+    the cryptic curses names to the Ada names in this <a href=
+    "ada/table.html">table</a>.</li>
+
+    <li>This is not a typical one-to-one interface mapping. It is
+    close to one-to-one on the functional level. Each (n)curses
+    function has its counterpart with a more or less similar
+    formal parameter list in the binding. It is not one-to-one with
+    respect to the datatypes. I tried to make records out of the
+    flat chtype and similar structures, so you don't have to do bit
+    operations to mark an attributed character as bold. Just make
+    the boolean member <strong>bold</strong> of the record true.
+    The binding also hides the structures like WINDOW, PANEL, MENU,
+    FORM etc. ! It is a pure functional API.</li>
+
+    <li>I try to do as much error checking as possible and feasible
+    in the binding. I will raise an Ada exception when something
+    went wrong in the low-level curses. This has the effect that -
+    at least first time in my life - (n)curses programs have now a
+    very rigid error checking, but - thanks to Ada - you don't have
+    to code the orgiastic error checking style of C.</li>
+
+    <li>Support for wide characters is currently not in the
+    binding, as it is not really in ncurses at this point in
+    time.</li>
+  </ul>
+
+  <h2>Limitations</h2>
+
+  <ul>
+    <li>I provide no SCREEN datatype and functions to set a new
+    screen. If you need this (mostly for debugging I guess), write
+    a small C routine doing all this and import it into your Ada
+    program.</li>
+
+    <li>I provide no functions to switch on/off curses tracing
+    options. Same suggestion as above.</li>
+
+    <li>Although Ada95 is an OO Language, this binding doesn't
+    provide an OO abstraction of the (n)curses functionality. As
+    mentioned above it is a thin binding for the (n)curses
+    functions. But without any doubt it would be nice to build on
+    top of this an OO abstraction of (n)curses functionality.<br>
+    The only exception is the method how fieldtypes are represented
+    in this Binding. We provide an abstract tagged type Field_Type
+    from which the various fieldtypes are derived.</li>
+
+    <li>I currently do not support the link_fieldtype functionality
+    of the forms subsystem.</li>
+
+    <li>The *_IO packages are currently output only.</li>
+  </ul>

+
+  <h2>Implementation Details</h2>
+
+  <h4>Behind the abstraction</h4>
+
+  <p>All the new types like <strong>Window</strong>,
+  <strong>Panel</strong>, <strong>Menu</strong>,
+  <strong>Form</strong> etc. are just opaque representations of the
+  pointers to the corresponding low level (n)curses structures like
+  <strong>WINDOW *</strong>, <strong>PANEL *</strong>, <strong>MENU
+  *</strong> or <strong>FORM *</strong>. So you can safely pass
+  them to C routines that expect a pointer to one of those
+  structures.</p>
+
+  <h4>Extended ripoffline() usage</h4>
+
+  <p>The official documentation of (n)curses says, that the line
+  parameter determines only whether or not exactly
+  <strong>one</strong> line is stolen from the top or bottom of the
+  screen. So essentially only the sign of the parameter is
+  evaluated. ncurses has internally implemented it in a way, that
+  uses the line parameter also to control the amount of lines to
+  steal. This mechanism is used in the
+  <strong>Rip_Off_Lines</strong> routine of the binding.</p>
+
+  <h4><a name="userpointer" id="userpointer">How user defined field
+  types work</a></h4>
+
+  <p>TBD</p>
+
+  <h4>Enumeration fields handling</h4>
+
+  <p>The (n)curses documentation says, that the String arrays to be
+  passed to an TYPE_ENUM fieldtype must not be automatic variables.
+  This is not true in this binding, because it is internally
+  arranged to safely copy these values.</p>
+
+  <h4><a name="compiler" id="compiler">Using other Ada
+  compilers</a></h4>
+
+  <p>This should basically not be a problem.</p>
+
+  <h4>Port to other curses implementations</h4>
+
+  <p>Basically it should not be too hard to make all this run on a
+  regular SVr4 implementation of curses. The problems are probably
+  these:<br></p>
+
+  <ul>
+    <li>ncurses has some additional features which are presented in
+    this binding. You have two choices to deal with this:
+
+      <ul>
+        <li>Emulate the feature in this binding</li>
+
+        <li>Raise an exception for non implemented features</li>
+      </ul>
+
+      <p>Most likely you will follow a mixed approach. Some
+      features are easy to simulate, others will be hard if not
+      impossible.</p>
+    </li>
+  </ul>
+
+  <p>I'm quite sure I forgot something.</p>

+      Introduction</a></h2>
+
+      <p>In the olden days of teletype terminals, terminals were
+      away from computers and were connected to them through serial
+      cables. The terminals could be configured by sending a series
+      of bytes. All the capabilities (such as moving the cursor to
+      a new location, erasing part of the screen, scrolling the
+      screen, changing modes, etc.) of terminals could be accessed
+      through these series of bytes. These control seeuqnces are
+      usually called escape sequences, because they start with an
+      escape(0x1B) character. Even today, with proper emulation, we
+      can send escape sequences to the emulator and achieve the
+      same effect on a terminal window.</p>
+
+      <p>Suppose you wanted to print a line in color. Try typing
+      this on your console.</p>
+
+      <pre class="PROGRAMLISTING">echo "^[[0;31;40mIn Color"</pre>
+      <p>The first character is an escape character, which looks
+      like two characters ^ and [. To be able to print it, you have
+      to press CTRL+V and then the ESC key. All the others are
+      normal printable characters. You should be able to see the
+      string "In Color" in red. It stays that way and to revert
+      back to the original mode type this.</p>
+
+      <pre class="PROGRAMLISTING">echo "^[[0;37;40m"</pre>
+      <p>Now, what do these magic characters mean? Difficult to
+      comprehend? They might even be different for different
+      terminals. So the designers of UNIX invented a mechanism
+      named <tt class="LITERAL">termcap</tt>. It is a file that
+      lists all the capabilities of a particular terminal, along
+      with the escape sequences needed to achieve a particular
+      effect. In the later years, this was replaced by <tt class=
+      "LITERAL">terminfo</tt>. Without delving too much into
+      details, this mechanism allows application programs to query
+      the terminfo database and obtain the control characters to be
+      sent to a terminal or terminal emulator.</p>

+      <div class="SECT2">

+        <h3 class="SECT2"><a name="WHATIS" id="WHATIS">1.1. What is
+        NCURSES?</a></h3>
+
+        <p>You might be wondering, what the import of all this
+        technical gibberish is. In the above scenario, every
+        application program is supposed to query the terminfo and
+        perform the necessary stuff (sending control characters,
+        etc.). It soon became difficult to manage this complexity
+        and this gave birth to 'CURSES'. Curses is a pun on the
+        name "cursor optimization". The Curses library forms a
+        wrapper over working with raw terminal codes, and provides
+        highly flexible and efficient API (Application Programming
+        Interface). It provides functions to move the cursor,
+        create windows, produce colors, play with mouse, etc. The
+        application programs need not worry about the underlying
+        terminal capabilities.</p>
+
+        <p>So what is NCURSES? NCURSES is a clone of the original
+        System V Release 4.0 (SVr4) curses. It is a freely
+        distributable library, fully compatible with older version
+        of curses. In short, it is a library of functions that
+        manages an application's display on character-cell
+        terminals. In the remainder of the document, the terms
+        curses and ncurses are used interchangeably.</p>
+
+        <p>A detailed history of NCURSES can be found in the NEWS
+        file from the source distribution. The current package is
+        maintained by <a href="mailto:dickey@invisible-island.net"
+        target="_top">Thomas Dickey</a>. You can contact the
+        maintainers at <a href="mailto:bug-ncurses@gnu.org" target=
+        "_top">bug-ncurses@gnu.org</a>.</p>

+
+        <p>NCURSES not only creates a wrapper over terminal
+        capabilities, but also gives a robust framework to create
+        nice looking UI (User Interface)s in text mode. It provides
+        functions to create windows, etc. Its sister libraries
+        panel, menu and form provide an extension to the basic
+        curses library. These libraries usually come along with
+        curses. One can create applications that contain multiple
+        windows, menus, panels and forms. Windows can be managed
+        independently, can provide 'scrollability' and even can be
+        hidden.</p>
+
+        <p>Menus provide the user with an easy command selection
+        option. Forms allow the creation of easy-to-use data entry
+        and display windows. Panels extend the capabilities of
+        ncurses to deal with overlapping and stacked windows.</p>
+
+        <p>These are just some of the basic things we can do with
+        ncurses. As we move along, We will see all the capabilities
+        of these libraries.</p>

+          <h4 class="SECT3"><a name="ABOUT-INITSCR" id=
+          "ABOUT-INITSCR">2.2.1. About initscr()</a></h4>
+
+          <p>The function initscr() initializes the terminal in
+          curses mode. In some implementations, it clears the
+          screen and presents a blank screen. To do any screen
+          manipulation using curses package this has to be called
+          first. This function initializes the curses system and
+          allocates memory for our present window (called
+          <tt class="LITERAL">stdscr</tt>) and some other
+          data-structures. Under extreme cases this function might
+          fail due to insufficient memory to allocate memory for
+          curses library's data structures.</p>
+
+          <p>After this is done, we can do a variety of
+          initializations to customize our curses settings. These
+          details will be explained <a href="#INIT">later</a> .</p>
+        </div>

+
+          <h4 class="SECT3"><a name="MYST-REFRESH" id=
+          "MYST-REFRESH">2.2.2. The mysterious refresh()</a></h4>
+
+          <p>The next line printw prints the string "Hello World
+          !!!" on to the screen. This function is analogous to
+          normal printf in all respects except that it prints the
+          data on a window called stdscr at the current (y,x)
+          co-ordinates. Since our present co-ordinates are at 0,0
+          the string is printed at the left hand corner of the
+          window.</p>
+
+          <p>This brings us to that mysterious refresh(). Well,
+          when we called printw the data is actually written to an
+          imaginary window, which is not updated on the screen yet.
+          The job of printw is to update a few flags and data
+          structures and write the data to a buffer corresponding
+          to stdscr. In order to show it on the screen, we need to
+          call refresh() and tell the curses system to dump the
+          contents on the screen.</p>
+
+          <p>The philosophy behind all this is to allow the
+          programmer to do multiple updates on the imaginary screen
+          or windows and do a refresh once all his screen update is
+          done. refresh() checks the window and updates only the
+          portion which has been changed. This improves performance
+          and offers greater flexibility too. But, it is sometimes
+          frustrating to beginners. A common mistake committed by
+          beginners is to forget to call refresh() after they did
+          some update through printw() class of functions. I still
+          forget to add it sometimes :-)</p>

+
+          <p>And finally don't forget to end the curses mode.
+          Otherwise your terminal might behave strangely after the
+          program quits. endwin() frees the memory taken by curses
+          sub-system and its data structures and puts the terminal
+          in normal mode. This function must be called after you
+          are done with the curses mode.</p>

+
+      <p>We now know that to initialize curses system the function
+      initscr() has to be called. There are functions which can be
+      called after this initialization to customize our curses
+      session. We may ask the curses system to set the terminal in
+      raw mode or initialize color or initialize the mouse, etc.
+      Let's discuss some of the functions that are normally called
+      immediately after initscr();</p>

+        raw() and cbreak()</a></h3>
+
+        <p>Normally the terminal driver buffers the characters a
+        user types until a new line or carriage return is
+        encountered. But most programs require that the characters
+        be available as soon as the user types them. The above two
+        functions are used to disable line buffering. The
+        difference between these two functions is in the way
+        control characters like suspend (CTRL-Z), interrupt and
+        quit (CTRL-C) are passed to the program. In the raw() mode
+        these characters are directly passed to the program without
+        generating a signal. In the <tt class=
+        "LITERAL">cbreak()</tt> mode these control characters are
+        interpreted as any other character by the terminal driver.
+        I personally prefer to use raw() as I can exercise greater
+        control over what the user does.</p>

+        echo() and noecho()</a></h3>
+
+        <p>These functions control the echoing of characters typed
+        by the user to the terminal. <tt class=
+        "LITERAL">noecho()</tt> switches off echoing. The reason
+        you might want to do this is to gain more control over
+        echoing or to suppress unnecessary echoing while taking
+        input from the user through the getch(), etc. functions.
+        Most of the interactive programs call <tt class=
+        "LITERAL">noecho()</tt> at initialization and do the
+        echoing of characters in a controlled manner. It gives the
+        programmer the flexibility of echoing characters at any
+        place in the window without updating current (y,x)
+        co-ordinates.</p>

+
+        <p>This is my favorite initialization function. It enables
+        the reading of function keys like F1, F2, arrow keys, etc.
+        Almost every interactive program enables this, as arrow
+        keys are a major part of any User Interface. Do <tt class=

+
+        <p>This function, though not used very often, is a useful
+        one at times. halfdelay()is called to enable the half-delay
+        mode, which is similar to the cbreak() mode in that
+        characters typed are immediately available to program.
+        However, it waits for 'X' tenths of a second for input and
+        then returns ERR, if no input is available. 'X' is the

+        "LITERAL">getch()</tt> is used to get a character from
+        user. It is equivalent to normal <tt class=
+        "LITERAL">getchar()</tt> except that we can disable the
+        line buffering to avoid &lt;enter&gt; after input. Look for
+        more about <tt class="LITERAL">getch()</tt>and reading keys
+        in the <a href="#KEYS">key management section</a> . The
+        functions attron and attroff are used to switch some

+      A Word about Windows</a></h2>
+
+      <p>Before we plunge into the myriad ncurses functions, let me
+      clear few things about windows. Windows are explained in
+      detail in following <a href="#WINDOWS">sections</a></p>
+
+      <p>A Window is an imaginary screen defined by curses system.
+      A window does not mean a bordered window which you usually
+      see on Win9X platforms. When curses is initialized, it
+      creates a default window named <tt class=
+      "LITERAL">stdscr</tt> which represents your 80x25 (or the
+      size of window in which you are running) screen. If you are
+      doing simple tasks like printing few strings, reading input,
+      etc., you can safely use this single window for all of your
+      purposes. You can also create windows and call functions
+      which explicitly work on the specified window.</p>
+
+      <p>For example, if you call</p>
+
+      <pre class="PROGRAMLISTING">    printw("Hi There !!!");
+    refresh();</pre>
+      <p>It prints the string on stdscr at the present cursor
+      position. Similarly the call to refresh(), works on stdscr
+      only.</p>
+
+      <p>Say you have created <a href="#WINDOWS">windows</a> then
+      you have to call a function with a 'w' added to the usual
+      function.</p>
+
+      <pre class="PROGRAMLISTING">    wprintw(win, "Hi There !!!");
+    wrefresh(win);</pre>
+      <p>As you will see in the rest of the document, naming of
+      functions follow the same convention. For each function there
+      usually are three more functions.</p>
+
+      <pre class=
+      "PROGRAMLISTING">    printw(string);        /* Print on stdscr at present cursor position */
+    mvprintw(y, x, string);/* Move to (y, x) then print string     */
+    wprintw(win, string);  /* Print on window win at present cursor position */
+                           /* in the window */
+    mvwprintw(win, y, x, string);   /* Move to (y, x) relative to window */
+                                    /* co-ordinates and then print         */</pre>
+      <p>Usually the w-less functions are macros which expand to
+      corresponding w-function with stdscr as the window
+      parameter.</p>

+
+      <p>I guess you can't wait any more to see some action. Back
+      to our odyssey of curses functions. Now that curses is
+      initialized, let's interact with world.</p>
+
+      <p>There are three classes of functions which you can use to
+      do output on screen.</p>
+
+      <ol type="1">
+        <li>
+          <p>addch() class: Print single character with
+          attributes</p>
+        </li>
+
+        <li>
+          <p>printw() class: Print formatted output similar to
+          printf()</p>
+        </li>
+
+        <li>
+          <p>addstr() class: Print strings</p>
+        </li>
+      </ol>
+
+      <p>These functions can be used interchangeably and it is a
+      matter of style as to which class is used. Let's see each one
+      in detail.</p>
+
+      <div class="SECT2">
+        <hr>
+
+        <h3 class="SECT2"><a name="ADDCHCLASS" id="ADDCHCLASS">6.1.
+        addch() class of functions</a></h3>
+
+        <p>These functions put a single character into the current
+        cursor location and advance the position of the cursor. You
+        can give the character to be printed but they usually are
+        used to print a character with some attributes. Attributes
+        are explained in detail in later <a href=
+        "#ATTRIB">sections</a> of the document. If a character is
+        associated with an attribute(bold, reverse video etc.),
+        when curses prints the character, it is printed in that
+        attribute.</p>
+
+        <p>In order to combine a character with some attributes,
+        you have two options:</p>
+
+        <ul>
+          <li>
+            <p>By OR'ing a single character with the desired
+            attribute macros. These attribute macros could be found
+            in the header file <tt class="LITERAL">ncurses.h</tt>.
+            For example, you want to print a character ch(of type
+            char) bold and underlined, you would call addch() as
+            below.</p>
+
+            <pre class=
+            "PROGRAMLISTING">    addch(ch | A_BOLD | A_UNDERLINE);</pre>
+          </li>
+
+          <li>
+            <p>By using functions like <tt class=
+            "LITERAL">attrset(),attron(),attroff()</tt>. These
+            functions are explained in the <a href=
+            "#ATTRIB">Attributes</a> section. Briefly, they
+            manipulate the current attributes of the given window.
+            Once set, the character printed in the window are
+            associated with the attributes until it is turned
+            off.</p>
+          </li>
+        </ul>
+
+        <p>Additionally, <tt class="LITERAL">curses</tt> provides
+        some special characters for character-based graphics. You
+        can draw tables, horizontal or vertical lines, etc. You can
+        find all available characters in the header file <tt class=
+        "LITERAL">ncurses.h</tt>. Try looking for macros beginning
+        with <tt class="LITERAL">ACS_</tt> in this file.</p>

+
+        <pre class="PROGRAMLISTING">    mvaddch(row,col,ch);</pre>
+        <p><tt class="LITERAL">waddch()</tt> is similar to

+        character into the given window. (Note that <tt class=

+        <tt class="LITERAL">stdscr</tt>.)</p>
+
+        <p>In a similar fashion <tt class="LITERAL">mvwaddch()</tt>
+        function is used to add a character into the given window

+
+        <p>Now, we are familiar with the basic output function
+        <tt class="LITERAL">addch()</tt>. But, if we want to print
+        a string, it would be very annoying to print it character
+        by character. Fortunately, <tt class="LITERAL">ncurses</tt>
+        provides <tt class="LITERAL">printf</tt><span class=

+        For example if you don't use the function cbreak(), curses
+        will not read your input characters contiguously but will
+        begin read them only after a new line or an EOF is
+        encountered. In order to avoid this, the cbreak() function
+        must used so that characters are immediately available to

+      <p>Don't worry about all those initialization and other crap.
+      Concentrate on the while loop. It reads each character in the
+      file and searches for the pattern /*. Once it spots the
+      pattern, it switches the BOLD attribute on with <tt class=
+      "LITERAL">attron()</tt> . When we get the pattern */ it is
+      switched off by <tt class="LITERAL">attroff()</tt> .</p>
+
+      <p>The above program also introduces us to two useful
+      functions <tt class="LITERAL">getyx()</tt> and <tt class=
+      "LITERAL">move()</tt>. The first function gets the
+      co-ordinates of the present cursor into the variables y, x.
+      Since getyx() is a macro we don't have to pass pointers to
+      variables. The function <tt class="LITERAL">move()</tt> moves
+      the cursor to the co-ordinates given to it.</p>
+
+      <p>The above program is really a simple one which doesn't do
+      much. On these lines one could write a more useful program

+
+        <p>Then what is the difference between attron() and
+        attrset()? attrset sets the attributes of window whereas
+        attron just switches on the attribute given to it. So
+        attrset() fully overrides whatever attributes the window
+        previously had and sets it to the new attribute(s).
+        Similarly attroff() just switches off the attribute(s)
+        given to it as an argument. This gives us the flexibility
+        of managing attributes easily.But if you use them
+        carelessly you may loose track of what attributes the
+        window has and garble the display. This is especially true
+        while managing menus with colors and highlighting. So
+        decide on a consistent policy and stick to it. You can
+        always use <tt class="LITERAL">standend()</tt> which is
+        equivalent to <tt class="LITERAL">attrset(A_NORMAL)</tt>
+        which turns off all attributes and brings you to normal
+        mode.</p>

+
+        <p>The function attr_get() gets the current attributes and

+        often as the above functions, this is useful in scanning
+        areas of screen. Say we wanted to do some complex update on
+        screen and we are not sure what attribute each character is
+        associated with. Then this function can be used with either
+        attrset or attron to produce the desired effect.</p>

+        can be used to set attributes for a group of characters
+        without moving. I mean it !!! without moving the cursor :-)
+        It changes the attributes of a given number of characters
+        starting at the current cursor location.</p>
+
+        <p>We can give -1 as the character count to update till end

+        <p>This function is useful when changing attributes for
+        characters that are already on the screen. Move to the
+        character from which you want to change and change the
+        attribute.</p>
+
+        <p>Other functions wchgat(), mvchgat(), wchgat() behave
+        similarly except that the w functions operate on the
+        particular window. The mv functions first move the cursor
+        then perform the work given to them. Actually chgat is a
+        macro which is replaced by a wchgat() with stdscr as the

+      Windows</a></h2>
+
+      <p>Windows form the most important concept in curses. You
+      have seen the standard window stdscr above where all the
+      functions implicitly operated on this window. Now to make
+      design even a simplest GUI, you need to resort to windows.
+      The main reason you may want to use windows is to manipulate
+      parts of the screen separately, for better efficiency, by
+      updating only the windows that need to be changed and for a
+      better design. I would say the last reason is the most
+      important in going for windows. You should always strive for
+      a better and easy-to-manage design in your programs. If you
+      are writing big, complex GUIs this is of pivotal importance
+      before you start doing anything.</p>

+
+        <p>A Window can be created by calling the function
+        <tt class="LITERAL">newwin()</tt>. It doesn't create any
+        thing on the screen actually. It allocates memory for a
+        structure to manipulate the window and updates the
+        structure with data regarding the window such as its size,
+        beginy, beginx, etc. Hence in curses, a window is just an
+        abstraction of an imaginary window, which can be
+        manipulated independent of other parts of screen. The
+        function newwin() returns a pointer to structure WINDOW,
+        which can be passed to window related functions such as
+        wprintw(), etc. Finally the window can be destroyed with
+        delwin(). It will deallocate the memory associated with the
+        window structure.</p>

+
+        <p>Don't scream. I know it is a big example. But I have to
+        explain some important things here :-). This program
+        creates a rectangular window that can be moved with left,
+        right, up, down arrow keys. It repeatedly creates and
+        destroys windows as user press a key. Don't go beyond the
+        screen limits. Checking for those limits is left as an
+        exercise for the reader. Let's dissect it by line by
+        line.</p>
+
+        <p>The <tt class="LITERAL">create_newwin()</tt> function
+        creates a window with <tt class="LITERAL">newwin()</tt> and
+        displays a border around it with box. The function
+        <tt class="LITERAL">destroy_win()</tt> first erases the
+        window from screen by painting a border with ' ' character
+        and then calling <tt class="LITERAL">delwin()</tt> to
+        deallocate memory related to it. Depending on the key the
+        user presses, starty or startx is changed and a new window
+        is created.</p>
+
+        <p>In the destroy_win, as you can see, I used wborder
+        instead of box. The reason is written in the comments (You
+        missed it. I know. Read the code :-)). wborder draws a
+        border around the window with the characters given to it as
+        the 4 corner points and the 4 lines. To put it clearly, if
+        you have called wborder as below:</p>
+
+        <pre class=
+        "PROGRAMLISTING">    wborder(win, '|', '|', '-', '-', '+', '+', '+', '+');</pre>
+        <p>it produces something like</p>

+
+        <p>You can also see in the above examples, that I have used
+        the variables COLS, LINES which are initialized to the
+        screen sizes after initscr(). They can be useful in finding
+        screen dimensions and finding the center co-ordinate of the
+        screen as above. The function <tt class=
+        "LITERAL">getch()</tt> as usual gets the key from keyboard
+        and according to the key it does the corresponding work.
+        This type of switch- case is very common in any GUI based
+        programs.</p>

+
+        <p>Above program is grossly inefficient in that with each
+        press of a key, a window is destroyed and another is
+        created. So let's write a more efficient program which uses
+        other border related functions.</p>
+
+        <p>The following program uses <tt class=
+        "LITERAL">mvhline()</tt> and <tt class=
+        "LITERAL">mvvline()</tt> to achieve similar effect. These
+        two functions are simple. They create a horizontal or

+
+        <p>As you can see, to start using color, you should first
+        call the function <tt class="LITERAL">start_color()</tt>.
+        After that, you can use color capabilities of your
+        terminals using various functions. To find out whether a
+        terminal has color capabilities or not, you can use
+        <tt class="LITERAL">has_colors()</tt> function, which
+        returns FALSE if the terminal does not support color.</p>
+
+        <p>Curses initializes all the colors supported by terminal
+        when start_color() is called. These can be accessed by the
+        define constants like <tt class="LITERAL">COLOR_BLACK</tt>
+        , etc. Now to actually start using colors, you have to
+        define pairs. Colors are always used in pairs. That means
+        you have to use the function <tt class=
+        "LITERAL">init_pair()</tt> to define the foreground and
+        background for the pair number you give. After that that
+        pair number can be used as a normal attribute with
+        <tt class="LITERAL">COLOR_PAIR()</tt>function. This may
+        seem to be cumbersome at first. But this elegant solution
+        allows us to manage color pairs very easily. To appreciate
+        it, you have to look into the the source code of "dialog",
+        a utility for displaying dialog boxes from shell scripts.
+        The developers have defined foreground and background
+        combinations for all the colors they might need and
+        initialized at the beginning. This makes it very easy to
+        set attributes just by accessing a pair which we already
+        have defined as a constant.</p>
+
+        <p>The following colors are defined in <tt class=
+        "LITERAL">curses.h</tt>. You can use these as parameters
+        for various color functions.</p>

+
+        <p>No GUI is complete without a strong user interface and
+        to interact with the user, a curses program should be
+        sensitive to key presses or the mouse actions done by the
+        user. Let's deal with the keys first.</p>
+
+        <p>As you have seen in almost all of the above examples, it
+        is very easy to get key input from the user. A simple way
+        of getting key presses is to use <tt class=
+        "LITERAL">getch()</tt> function. The cbreak mode should be
+        enabled to read keys when you are interested in reading
+        individual key hits rather than complete lines of text
+        (which usually end with a carriage return). keypad should
+        be enabled to get the Functions keys, arrow keys, etc. See
+        the initialization section for details.</p>
+
+        <p><tt class="LITERAL">getch()</tt> returns an integer
+        corresponding to the key pressed. If it is a normal
+        character, the integer value will be equivalent to the
+        character. Otherwise it returns a number which can be
+        matched with the constants defined in <tt class=
+        "LITERAL">curses.h</tt>. For example if the user presses
+        F1, the integer returned is 265. This can be checked using
+        the macro KEY_F() defined in curses.h. This makes reading
+        keys portable and easy to manage.</p>
+
+        <p>For example, if you call getch() like this</p>
+
+        <pre class="PROGRAMLISTING">    int ch;
+
+    ch = getch();</pre>
+        <p>getch() will wait for the user to press a key, (unless
+        you specified a timeout) and when user presses a key, the
+        corresponding integer is returned. Then you can check the
+        value returned with the constants defined in curses.h to
+        match against the keys you want.</p>
+
+        <p>The following code piece will do that job.</p>
+

+

+      give a professional windows-type look. Unfortunately, it soon
+      becomes difficult to manage these. The multiple refreshes,

+      create blotches, whenever you forget to refresh the windows
+      in the proper order.</p>
+
+      <p>Don't despair. There is an elegant solution provided in
+      panels library. In the words of developers of ncurses</p>
+
+      <p><span class="emphasis"><i class="EMPHASIS">When your

+      </p>
+
+      <p>If you have lot of overlapping windows, then panels
+      library is the way to go. It obviates the need of doing
+      series of wnoutrefresh(), doupdate() and relieves the burden
+      of doing it correctly(bottom up). The library maintains
+      information about the order of windows, their overlapping and
+      update the screen properly. So why wait? Let's take a close
+      peek into panels.</p>

+        <h3 class="SECT2"><a name="PANELBASICS" id=
+        "PANELBASICS">16.1. The Basics</a></h3>
+
+        <p>Panel object is a window that is implicitly treated as
+        part of a deck including all other panel objects. The deck
+        is treated as a stack with the top panel being completely
+        visible and the other panels may or may not be obscured
+        according to their positions. So the basic idea is to
+        create a stack of overlapping panels and use panels library
+        to display them correctly. There is a function similar to
+        refresh() which, when called , displays panels in the
+        correct order. Functions are provided to hide or show
+        panels, move panels, change its size, etc. The overlapping
+        problem is managed by the panels library during all the
+        calls to these functions.</p>
+
+        <p>The general flow of a panel program goes like this:</p>
+
+        <ol type="1">
+          <li>
+            <p>Create the windows (with newwin()) to be attached to
+            the panels.</p>
+          </li>
+
+          <li>
+            <p>Create panels with the chosen visibility order.
+            Stack them up according to the desired visibility. The
+            function new_panel() is used to created panels.</p>
+          </li>
+
+          <li>
+            <p>Call update_panels() to write the panels to the
+            virtual screen in correct visibility order. Do a
+            doupdate() to show it on the screen.</p>
+          </li>
+
+          <li>
+            <p>Mainpulate the panels with show_panel(),
+            hide_panel(), move_panel(), etc. Make use of helper
+            functions like panel_hidden() and panel_window(). Make
+            use of user pointer to store custom data for a panel.
+            Use the functions set_panel_userptr() and
+            panel_userptr() to set and get the user pointer for a
+            panel.</p>
+          </li>
+
+          <li>
+            <p>When you are done with the panel use del_panel() to
+            delete the panel.</p>
+          </li>
+        </ol>
+
+        <p>Let's make the concepts clear, with some programs. The
+        following is a simple program which creates 3 overlapping
+        panels and shows them on the screen.</p>

+
+        <p>In the above example I used user pointers to find out
+        the next window in the cycle. We can attach custom
+        information to the panel by specifying a user pointer,
+        which can point to any information you want to store. In
+        this case I stored the pointer to the next panel in the
+        cycle. User pointer for a panel can be set with the
+        function <tt class="LITERAL">set_panel_userptr()</tt>. It
+        can be accessed using the function <tt class=
+        "LITERAL">panel_userptr()</tt> which will return the user
+        pointer for the panel given as argument. After finding the
+        next panel in the cycle, it is brought to the top by the
+        function top_panel(). This function brings the panel given
+        as argument to the top of the panel stack.</p>

+        "PANELMOVERESIZE">16.5. Moving and Resizing Panels</a></h3>
+
+        <p>The function <tt class="LITERAL">move_panel()</tt> can
+        be used to move a panel to the desired location. It does
+        not change the position of the panel in the stack. Make
+        sure that you use move_panel() instead mvwin() on the
+        window associated with the panel.</p>
+
+        <p>Resizing a panel is slightly complex. There is no
+        straight forward function just to resize the window
+        associated with a panel. A solution to resize a panel is to
+        create a new window with the desired sizes, change the
+        window associated with the panel using replace_panel().
+        Don't forget to delete the old window. The window
+        associated with a panel can be found by using the function
+        panel_window().</p>
+
+        <p>The following program shows these concepts, in
+        supposedly simple program. You can cycle through the window
+        with &lt;TAB&gt; as usual. To resize or move the active
+        panel press 'r' for resize 'm' for moving. Then use arrow
+        keys to resize or move it to the desired way and press
+        enter to end your resizing or moving. This example makes
+        use of user data to get the required data to do the
+        operations.</p>

+        <p>Concentrate on the main while loop. Once it finds out

+        'r' is pressed resizing mode is started. After this the new

+        the user presses &lt;ENTER&gt; present selection ends and
+        panel is resized by using the concept explained. While in
+        resizing mode the program doesn't show how the window is
+        getting resized. It is left as an exercise to the reader to
+        print a dotted border while it gets resized to a new
+        position.</p>
+
+        <p>When the user presses 'm' the move mode starts. This is
+        a bit simpler than resizing. As the arrow keys are pressed
+        the new position is updated and pressing of &lt;ENTER&gt;
+        causes the panel to be moved by calling the function
+        move_panel().</p>
+
+        <p>In this program the user data which is represented as
+        PANEL_DATA, plays very important role in finding the
+        associated information with a panel. As written in the
+        comments, the PANEL_DATA stores the panel sizes, label,
+        label color and a pointer to the next panel in the
+        cycle.</p>

+
+        <p>A Panel can be hidden by using the function
+        hide_panel(). This function merely removes it form the
+        stack of panels, thus hiding it on the screen once you do
+        update_panels() and doupdate(). It doesn't destroy the
+        PANEL structure associated with the hidden panel. It can be
+        shown again by using the show_panel() function.</p>
+
+        <p>The following program shows the hiding of panels. Press
+        'a' or 'b' or 'c' to show or hide first, second and third
+        windows respectively. It uses a user data with a small
+        variable hide, which keeps track of whether the window is
+        hidden or not. For some reason the function <tt class=
+        "LITERAL">panel_hidden()</tt> which tells whether a panel
+        is hidden or not is not working. A bug report was also
+        presented by Michael Andres <a href=

+      to give a nicer look, with colors, etc. Let's get into the
+      details.</p>
+
+      <p>A menu is a screen display that assists the user to choose
+      some subset of a given set of items. To put it simple, a menu
+      is a collection of items from which one or more items can be
+      chosen. Some readers might not be aware of multiple item
+      selection capability. Menu library provides functionality to
+      write menus from which the user can chose more than one item
+      as the preferred choice. This is dealt with in a later
+      section. Now it is time for some rudiments.</p>

+        to be done with the menu. According to the parameter,

+

+        important to understand various options it takes and what
+        they do. As explained above, the second parameter to
+        menu_driver() can be either a navigational request, a
+        printable character or a KEY_MOUSE key. Let's dissect the
+        different navigational requests.</p>

+            </p>
+
+            <p>A Menu can be displayed with multiple columns for
+            more than one item. This can be done by using the
+            <tt class="LITERAL">menu_format()</tt>function. When a
+            multi columnar menu is displayed these requests cause
+            the menu driver to move the current selection to left
+            or right.</p>
+          </li>
+
+          <li>
+            <p><span class="emphasis"><i class=

+            </p>
+
+            <p>These two options you have seen in the above
+            example. These options when given, makes the
+            menu_driver to move the current selection to an item up
+            or down.</p>

+

+            REQ_SCR_DPAGE, REQ_SCR_UPAGE are related to scrolling.
+            If all the items in the menu cannot be displayed in the
+            menu sub window, then the menu is scrollable. These
+            requests can be given to the menu_driver to do the

+
+            <p>This request when given, toggles the present
+            selection. This option is to be used only in a multi
+            valued menu. So to use this request the option
+            O_ONEVALUE must be off. This option can be made off or
+            on with set_menu_opts().</p>

+            Requests</i></span>
+            </p>
+
+            <p>Every menu has an associated pattern buffer, which
+            is used to find the nearest match to the ascii
+            characters entered by the user. Whenever ascii
+            characters are given to menu_driver, it puts in to the
+            pattern buffer. It also tries to find the nearest match
+            to the pattern in the items list and moves current
+            selection to that item. The request REQ_CLEAR_PATTERN
+            clears the pattern buffer. The request REQ_BACK_PATTERN
+            deletes the previous character in the pattern buffer.
+            In case the pattern matches more than one item then the
+            matched items can be cycled through REQ_NEXT_MATCH and
+            REQ_PREV_MATCH which move the current selection to the
+            next and previous matches respectively.</p>

+        number of choices has been increased to ten, which is
+        larger than our sub window size which can hold 6 items.
+        This message has to be explicitly conveyed to the menu
+        system with the function set_menu_format(). In here we
+        specify the number of rows and columns we want to be
+        displayed for a single page. We can specify any number of
+        items to be shown, in the rows variables, if it is less
+        than the height of the sub window. If the key pressed by
+        the user is a PAGE UP or PAGE DOWN, the menu is scrolled a
+        page due to the requests (REQ_SCR_DPAGE and REQ_SCR_UPAGE)
+        given to menu_driver().</p>

+
+        <p>Whew, A lot of new functions. Let's take them one after
+        another. Firstly, the REQ_TOGGLE_ITEM. In a multi-valued
+        menu, the user should be allowed to select or un select
+        more than one item. The request REQ_TOGGLE_ITEM toggles the
+        present selection. In this case when space is pressed
+        REQ_TOGGLE_ITEM request is sent to menu_driver to achieve
+        the result.</p>
+
+        <p>Now when the user presses &lt;ENTER&gt; we show the
+        items he presently selected. First we find out the items
+        associated with the menu using the function menu_items().
+        Then we loop through the items to find out if the item is
+        selected or not. The function item_value() returns TRUE if
+        an item is selected. The function item_count() returns the
+        number of items in the menu. The item name can be found
+        with item_name(). You can also find the description
+        associated with an item using item_description().</p>

+
+        <p>Well, by this time you must be itching for some
+        difference in your menu, with lots of functionality. I
+        know. You want Colors !!!. You want to create nice menus
+        similar to those text mode <a href=
+        "http://www.jersey.net/~debinjoe/games/" target="_top">dos
+        games</a>. The functions set_menu_fore() and
+        set_menu_back() can be used to change the attribute of the
+        selected item and unselected item. The names are
+        misleading. They don't change menu's foreground or
+        background which would have been useless.</p>
+
+        <p>The function set_menu_grey() can be used to set the
+        display attribute for the non-selectable items in the menu.
+        This brings us to the interesting option for an item the
+        one and only O_SELECTABLE. We can turn it off by the
+        function item_opts_off() and after that that item is not
+        selectable. It is like a grayed item in those fancy windows
+        menus. Let's put these concepts in practice with this
+        example</p>

+      Library</a></h2>
+
+      <p>Well. If you have seen those forms on web pages which take
+      input from users and do various kinds of things, you might be
+      wondering how would any one create such forms in text mode
+      display. It is quite difficult to write those nifty forms in
+      plain ncurses. Forms library tries to provide a basic frame
+      work to build and maintain forms with ease. It has lot of
+      features(functions) which manage validation, dynamic
+      expansion of fields, etc. Let's see it in full flow.</p>
+
+      <p>A form is a collection of fields; each field can be either
+      a label(static text) or a data-entry location. The forms also
+      library provides functions to divide forms into multiple
+      pages.</p>
+
+      <div class="SECT2">
+        <hr>
+
+        <h3 class="SECT2"><a name="FORMBASICS" id=
+        "FORMBASICS">18.1. The Basics</a></h3>
+
+        <p>Forms are created in much the same way as menus. First
+        the fields related to the form are created with
+        new_field(). You can set options for the fields, so that
+        they can be displayed with some fancy attributes, validated
+        before the field looses focus, etc. Then the fields are
+        attached to form. After this, the form can be posted to
+        display and is ready to receive inputs. On the similar
+        lines to menu_driver(), the form is manipulated with
+        form_driver(). We can send requests to form_driver to move
+        focus to a certain field, move cursor to end of the field
+        etc. After the user enters values in the fields and
+        validation done, form can be unposted and memory allocated
+        can be freed.</p>
+
+        <p>The general flow of control of a forms program looks
+        like this.</p>
+
+        <ol type="1">
+          <li>
+            <p>Initialize curses</p>
+          </li>
+
+          <li>
+            <p>Create fields using new_field(). You can specify the
+            height and width of the field, and its position on the
+            form.</p>
+          </li>
+
+          <li>
+            <p>Create the forms with new_form() by specifying the
+            fields to be attached with.</p>
+          </li>
+
+          <li>
+            <p>Post the form with form_post() and refresh the
+            screen.</p>
+          </li>
+
+          <li>
+            <p>Process the user requests with a loop and do
+            necessary updates to form with form_driver.</p>
+          </li>
+
+          <li>
+            <p>Unpost the menu with form_unpost()</p>
+          </li>
+
+          <li>
+            <p>Free the memory allocated to menu by free_form()</p>
+          </li>
+
+          <li>
+            <p>Free the memory allocated to the items with
+            free_field()</p>
+          </li>

+          <li>
+            <p>End curses</p>
+          </li>
+        </ol>
+
+        <p>As you can see, working with forms library is much
+        similar to handling menu library. The following examples
+        will explore various aspects of form processing. Let's
+        start the journey with a simple example. first.</p>

+
+        <p>Above example is pretty straight forward. It creates two
+        fields with <tt class="LITERAL">new_field()</tt>.
+        new_field() takes height, width, starty, startx, number of
+        offscreen rows and number of additional working buffers.
+        The fifth argument number of offscreen rows specifies how
+        much of the field to be shown. If it is zero, the entire
+        field is always displayed otherwise the form will be
+        scrollable when the user accesses not displayed parts of
+        the field. The forms library allocates one buffer per field
+        to store the data user enters. Using the last parameter to
+        new_field() we can specify it to allocate some additional
+        buffers. These can be used for any purpose you like.</p>
+
+        <p>After creating the fields, back ground attribute of both
+        of them is set to an underscore with set_field_back(). The
+        AUTOSKIP option is turned off using field_opts_off(). If
+        this option is turned on, focus will move to the next field
+        in the form once the active field is filled up
+        completely.</p>

+          <p>Though above functions seem quite simple, using colors
+          with set_field_fore() may be frustrating in the
+          beginning. Let me first explain about foreground and
+          background attributes of a field. The foreground
+          attribute is associated with the character. That means a
+          character in the field is printed with the attribute you
+          have set with set_field_fore(). Background attribute is
+          the attribute used to fill background of field, whether
+          any character is there or not. So what about colors?
+          Since colors are always defined in pairs, what is the
+          right way to display colored fields? Here's an example
+          clarifying color attributes.</p>

+          one line field. A new field created with height greater
+          than one will be defined to be a multi line field.</p>
+
+          <p>A one line field with O_STATIC turned off (dynamically

+          number of columns can increase if the user enters more
+          data than the initial field will hold. The number of
+          columns displayed will remain fixed and the additional
+          data will scroll horizontally.</p>
+
+          <p>A multi line field with O_STATIC turned off
+          (dynamically growable field) will contain a fixed number
+          of columns, but the number of rows can increase if the
+          user enters more data than the initial field will hold.
+          The number of rows displayed will remain fixed and the
+          additional data will scroll vertically.</p>
+
+          <p>The above two paragraphs pretty much describe a
+          dynamically growable field's behavior. The way other
+          parts of forms library behaves is described below:</p>
+
+          <ol type="1">
+            <li>
+              <p>The field option O_AUTOSKIP will be ignored if the
+              option O_STATIC is off and there is no maximum growth
+              specified for the field. Currently, O_AUTOSKIP
+              generates an automatic REQ_NEXT_FIELD form driver
+              request when the user types in the last character
+              position of a field. On a growable field with no
+              maximum growth specified, there is no last character
+              position. If a maximum growth is specified, the
+              O_AUTOSKIP option will work as normal if the field
+              has grown to its maximum size.</p>
+            </li>
+
+            <li>
+              <p>The field justification will be ignored if the
+              option O_STATIC is off. Currently, set_field_just can
+              be used to JUSTIFY_LEFT, JUSTIFY_RIGHT,
+              JUSTIFY_CENTER the contents of a one line field. A
+              growable one line field will, by definition, grow and
+              scroll horizontally and may contain more data than
+              can be justified. The return from field_just will be
+              unchanged.</p>
+            </li>
+
+            <li>
+              <p>The overloaded form driver request REQ_NEW_LINE
+              will operate the same way regardless of the
+              O_NL_OVERLOAD form option if the field option
+              O_STATIC is off and there is no maximum growth
+              specified for the field. Currently, if the form
+              option O_NL_OVERLOAD is on, REQ_NEW_LINE implicitly
+              generates a REQ_NEXT_FIELD if called from the last
+              line of a field. If a field can grow without bound,
+              there is no last line, so REQ_NEW_LINE will never
+              implicitly generate a REQ_NEXT_FIELD. If a maximum
+              growth limit is specified and the O_NL_OVERLOAD form
+              option is on, REQ_NEW_LINE will only implicitly
+              generate REQ_NEXT_FIELD if the field has grown to its
+              maximum size and the user is on the last line.</p>
+            </li>
+
+            <li>
+              <p>The library call dup_field will work as usual; it
+              will duplicate the field, including the current
+              buffer size and contents of the field being
+              duplicated. Any specified maximum growth will also be
+              duplicated.</p>
+            </li>
+
+            <li>
+              <p>The library call link_field will work as usual; it
+              will duplicate all field attributes and share buffers
+              with the field being linked. If the O_STATIC field
+              option is subsequently changed by a field sharing
+              buffers, how the system reacts to an attempt to enter
+              more data into the field than the buffer will
+              currently hold will depend on the setting of the
+              option in the current field.</p>
+            </li>
+
+            <li>
+              <p>The library call field_info will work as usual;
+              the variable nrow will contain the value of the
+              original call to new_field. The user should use
+              dynamic_field_info, described above, to query the
+              current size of the buffer.</p>
+            </li>
+          </ol>
+
+          <p>Some of the above points make sense only after
+          explaining form driver. We will be looking into that in
+          next few sections.</p>

+
+        <p>By default, a field will accept any data input by the
+        user. It is possible to attach validation to the field.
+        Then any attempt by the user to leave the field, while it
+        contains data that doesn't match the validation type will
+        fail. Some validation types also have a character-validity
+        check for each time a character is entered in the
+        field.</p>
+
+        <p>Validation can be attached to a field with the following
+        function.</p>
+
+        <pre class=
+        "PROGRAMLISTING">int set_field_type(FIELD *field,          /* field to alter */
+                   FIELDTYPE *ftype,      /* type to associate */
+                   ...);                  /* additional arguments*/</pre>Once
+set, the validation type for a field can be queried with
+
+        <pre class=
+        "PROGRAMLISTING">FIELDTYPE *field_type(FIELD *field);      /* field to query */</pre>
+        <p>The form driver validates the data in a field only when
+        data is entered by the end-user. Validation does not occur
+        when</p>
+
+        <ul>
+          <li>
+            <p>the application program changes the field value by

+            <p>linked field values are changed indirectly -- by
+            changing the field to which they are linked</p>
+          </li>
+        </ul>
+
+        <p>The following are the pre-defined validation types. You
+        can also specify custom validation, though it is a bit
+        tricky and cumbersome.</p>
+
+        <h1 class="BRIDGEHEAD"><a name="AEN1074" id=
+        "AEN1074"></a>TYPE_ALPHA</h1>
+
+        <p>This field type accepts alphabetic data; no blanks, no
+        digits, no special characters (this is checked at
+        character-entry time). It is set up with:</p>
+
+        <pre class=

+                   int width);            /* minimum width of field */</pre>
+        <p>The width argument sets a minimum width of data. The
+        user has to enter at-least width number of characters
+        before he can leave the field. Typically you'll want to set
+        this to the field width; if it is greater than the field
+        width, the validation check will always fail. A minimum
+        width of zero makes field completion optional.</p>
+
+        <h1 class="BRIDGEHEAD"><a name="AEN1078" id=
+        "AEN1078"></a>TYPE_ALNUM</h1>
+
+        <p>This field type accepts alphabetic data and digits; no
+        blanks, no special characters (this is checked at
+        character-entry time). It is set up with:</p>

+                   int width);            /* minimum width of field */</pre>
+        <p>The width argument sets a minimum width of data. As with
+        TYPE_ALPHA, typically you'll want to set this to the field
+        width; if it is greater than the field width, the
+        validation check will always fail. A minimum width of zero
+        makes field completion optional.</p>
+
+        <h1 class="BRIDGEHEAD"><a name="AEN1082" id=
+        "AEN1082"></a>TYPE_ENUM</h1>
+
+        <p>This type allows you to restrict a field's values to be
+        among a specified set of string values (for example, the
+        two-letter postal codes for U.S. states). It is set up
+        with:</p>
+
+        <pre class=
+        "PROGRAMLISTING">int set_field_type(FIELD *field,          /* field to alter */

+                   int checkcase;         /* case-sensitive? */
+                   int checkunique);      /* must specify uniquely? */</pre>
+        <p>The valuelist parameter must point at a NULL-terminated
+        list of valid strings. The checkcase argument, if true,
+        makes comparison with the string case-sensitive.</p>
+
+        <p>When the user exits a TYPE_ENUM field, the validation
+        procedure tries to complete the data in the buffer to a
+        valid entry. If a complete choice string has been entered,
+        it is of course valid. But it is also possible to enter a
+        prefix of a valid string and have it completed for you.</p>
+
+        <p>By default, if you enter such a prefix and it matches
+        more than one value in the string list, the prefix will be
+        completed to the first matching value. But the checkunique
+        argument, if true, requires prefix matches to be unique in
+        order to be valid.</p>
+
+        <p>The REQ_NEXT_CHOICE and REQ_PREV_CHOICE input requests
+        can be particularly useful with these fields.</p>

+
+        <p>If the value passes its range check, it is padded with

+
+          <p>The behavior of the REQ_NEW_LINE and REQ_DEL_PREV
+          requests is complicated and partly controlled by a pair
+          of forms options. The special cases are triggered when
+          the cursor is at the beginning of a field, or on the last
+          line of the field.</p>
+
+          <p>First, we consider REQ_NEW_LINE:</p>
+
+          <p>The normal behavior of REQ_NEW_LINE in insert mode is
+          to break the current line at the position of the edit
+          cursor, inserting the portion of the current line after
+          the cursor as a new line following the current and moving
+          the cursor to the beginning of that new line (you may
+          think of this as inserting a newline in the field
+          buffer).</p>
+
+          <p>The normal behavior of REQ_NEW_LINE in overlay mode is
+          to clear the current line from the position of the edit
+          cursor to end of line. The cursor is then moved to the
+          beginning of the next line.</p>
+
+          <p>However, REQ_NEW_LINE at the beginning of a field, or
+          on the last line of a field, instead does a
+          REQ_NEXT_FIELD. O_NL_OVERLOAD option is off, this special
+          action is disabled.</p>
+
+          <p>Now, let us consider REQ_DEL_PREV:</p>
+
+          <p>The normal behavior of REQ_DEL_PREV is to delete the
+          previous character. If insert mode is on, and the cursor
+          is at the start of a line, and the text on that line will
+          fit on the previous one, it instead appends the contents
+          of the current line to the previous one and deletes the
+          current line (you may think of this as deleting a newline
+          from the field buffer).</p>
+
+          <p>However, REQ_DEL_PREV at the beginning of a field is
+          instead treated as a REQ_PREV_FIELD.</p>
+
+          <p>If the O_BS_OVERLOAD option is off, this special
+          action is disabled and the forms driver just returns
+          E_REQUEST_DENIED.</p>

+                      A good widget for displaying the progress of
+                      something. (akin to a console window)
+Selection List        Creates a multiple option selection list.
+Slider                Akin to the scale widget, this widget provides a
+                      visual slide bar to represent the numeric value.
+Template              Creates a entry field with character sensitive 
+                      positions. Used for pre-formatted fields like
+                      dates and phone numbers.
+Viewer                This is a file/information viewer. Very useful
+                      when you need to display loads of information.

+
+          <p>Apart from making our life easier with readily usable
+          widgets, cdk solves one frustrating problem with printing
+          multi colored strings, justified strings elegantly.
+          Special formatting tags can be embedded in the strings
+          which are passed to CDK functions. For Example</p>
+
+          <p>If the string</p>
+
+          <pre class=

+background.&lt;!1&gt;"</pre>
+          <p>given as a parameter to newCDKLabel(), it prints the
+          line with yellow foreground and blue background. There
+          are other tags available for justifying string, embedding
+          special drawing characters, etc. Please refer to the man
+          page cdk_display(3X) for details. The man page explains
+          the usage with nice examples.</p>

+
+        <p>Long long ago, in September 1994, when few people knew
+        linux, Jeff Tranter wrote an <a href=
+        "http://www2.linuxjournal.com/lj-issues/issue5/2807.html"
+        target="_top">article</a> on dialog in Linux Journal. He
+        starts the article with these words..</p>
+
+        <p><span class="emphasis"><i class="EMPHASIS">Linux is
+        based on the Unix operating system, but also features a
+        number of unique and useful kernel features and application
+        programs that often go beyond what is available under Unix.
+        One little-known gem is "dialog", a utility for creating
+        professional-looking dialog boxes from within shell
+        scripts. This article presents a tutorial introduction to
+        the dialog utility, and shows examples of how and where it
+        can be used</i></span>
+        </p>
+
+        <p>As he explains, dialog is a real gem in making
+        professional-looking dialog boxes with ease. It creates a
+        variety of dialog boxes, menus, check lists, etc. It is
+        usually installed by default. If not, you can download it
+        from <a href="https://invisible-island.net/dialog/" target=
+        "_top">Thomas Dickey</a>'s site.</p>
+
+        <p>The above-mentioned article gives a very good overview
+        of its uses and capabilities. The man page has more
+        details. It can be used in variety of situations. One good
+        example is building of linux kernel in text mode. Linux
+        kernel uses a modified version of dialog tailored for its
+        needs.</p>
+
+        <p>dialog was initially designed to be used with shell
+        scripts. If you want to use its functionality in a c
+        program, then you can use libdialog. The documentation
+        regarding this is sparse. Definitive reference is the
+        dialog.h header file which comes with the library. You may
+        need to hack here and there to get the required output. The
+        source is easily customizable. I have used it on a number
+        of occasions by modifying the code.</p>

+
+        <p>The perl module Curses, Curses::Form and Curses::Widgets
+        give access to curses from perl. If you have curses and

+        can use these modules from perl scripts like any other
+        module. For more information on perl modules see perlmod
+        man page. The above modules come with good documentation
+        and they have some demo scripts to test the functionality.
+        Though the widgets provided are very rudimentary, these
+        modules provide good access to curses library from
+        perl.</p>
+
+        <p>Some of my code examples are converted to perl by

+
+  <h2><a name="h2-overview" id="h2-overview">Overview</a></h2>
+
+  <p>The <span class="main-name">ncurses</span> (new curses)
+  library is a free software emulation of curses in System V
+  Release 4.0 (SVr4), and more. It uses terminfo format, supports
+  pads and color and multiple highlights and forms characters and
+  function-key mapping, and has all the other SVr4-curses
+  enhancements over BSD curses. SVr4 curses became the basis of
+  X/Open Curses.</p>
+
+  <p>In mid-June 1995, the maintainer of 4.4BSD curses declared
+  that he considered 4.4BSD curses obsolete, and encouraged the
+  keepers of <span class="main-name">unix</span> releases such as
+  BSD/OS, FreeBSD and NetBSD to switch over to <span class=
+  "main-name">ncurses</span>.</p>
+
+  <p>Since 1995, <span class="main-name">ncurses</span> has been
+  ported to many systems:</p>
+
+  <ul>
+    <li>It is used in almost every system based on the Linux kernel
+    (aside from some embedded applications).</li>
+
+    <li>It is used as the system curses library on OpenBSD, FreeBSD
+    and MacOS.</li>
+
+    <li>It is used in environments such as Cygwin and MinGW. The
+    first of these was EMX on OS/2 Warp.</li>
+
+    <li>It is used (though usually not as the <em>system</em>
+    curses) on all of the vendor <span class=
+    "main-name">unix</span> systems, e.g., AIX, HP-UX, IRIX64, SCO,
+    Solaris, Tru64.</li>
+
+    <li>It should work readily on any ANSI/POSIX-conforming
+    <span class="main-name">unix</span>.</li>
+  </ul>
+
+  <p>The distribution includes the library and support utilities,
+  including</p>
+
+  <ul>
+    <li><a href="https://invisible-island.net/ncurses/man/captoinfo.1m.html"><span class=

+  <h2><a name="h2-release-notes" id="h2-release-notes">Release
+  Notes</a></h2>
+
+  <p>These notes are for <span class="main-name">ncurses</span>
+  6.4, released <strong>December 31, 2022</strong>.</p>
+
+  <p>This release is designed to be source-compatible with
+  <span class="main-name">ncurses</span> 5.0 through 6.3; providing
+  extensions to the application binary interface (ABI). Although
+  the source can still be configured to support the <span class=
+  "main-name">ncurses</span> 5 ABI, the reason for the release is
+  to reflect improvements to the <span class=
+  "main-name">ncurses</span> 6 ABI and the supporting utility
+  programs.</p>
+
+  <p>There are, of course, numerous other improvements, listed in
+  this announcement.</p>
+
+  <p>The most <a href="#h3-bug-fixes">important
+  bug-fixes/improvements</a> dealt with robustness issues. The
+  release notes also mention some other bug-fixes, but are focused
+  on new features and improvements to existing features since
+  <span class="main-name">ncurses</span> 6.3 release.</p>
+
+  <h3><a name="h3-library" id="h3-library">Library improvements</a></h3>
+
+  <h4><a name="h4-new-library" id="h4-new-library">New features</a></h4>
+
+  <p>There are no new features in this release.</p>
+
+  <h4><a name="h4-fixes-library" id="h4-fixes-library">Other
+  improvements</a></h4>
+
+  <p>These are improvements to existing features:</p>
+
+  <ul>
+    <li>
+      <p>modify <tt>delscreen</tt> to more effectively delete all
+      windows on the given screen.</p>
+    </li>
+
+    <li>
+      <p>modify <tt>wnoutrefresh</tt> to call <tt>pnoutrefresh</tt>
+      if its parameter is a pad, rather than treating it as an
+      error, and modify new_panel to permit its window-parameter to
+      be a pad</p>
+    </li>
+
+    <li>
+      <p>modify curses_trace() to show the trace-mask as symbols,
+      e.g., <tt>TRACE_ORDINARY</tt>, <tt>DEBUG_LEVEL(3)</tt>.</p>
+    </li>
+
+    <li>
+      <p>improve checks for valid mouse events when an intermediate
+      mouse state is not part of the mousemask specified by the
+      caller</p>
+    </li>
+
+    <li>
+      <p>allow extended-color number in <em>opts</em> parameter of
+      <tt>wattr_on</tt>.</p>
+    </li>
+
+    <li>
+      <p>improve <tt>_tracecchar_t2</tt> formatting of
+      base+combining character.</p>
+    </li>
+
+    <li>
+      <p>trim out some unwanted linker options from ncurses*config
+      and .pc files seen in Fedora 36+.</p>
+    </li>
+
+    <li>
+      <p>improve shell-scripts with <em>shellcheck</em></p>
+    </li>
+
+    <li>
+      <p>improve use of "trap" in shell scripts, using a
+      script.</p>
+    </li>
+
+    <li>
+      <p>modify <tt>make-tar.sh</tt> scripts to make timestamps
+      more predictable.</p>
+    </li>
+  </ul>
+
+  <p>These are corrections to existing features:</p>
+
+  <ul>
+    <li>
+      <p>modify <tt>misc/gen-pkgconfig.in</tt> to allow for the
+      case where the library directory does not yet exist, since
+      this is processed before doing an install</p>
+    </li>
+
+    <li>
+      <p>set trailing null on string passed from <tt>winsnstr</tt>
+      to <tt>wins_nwstr</tt>.</p>
+    </li>
+
+    <li>
+      <p>modify <tt>waddch_literal</tt> to allow for double-width
+      base character when merging a combining character</p>
+    </li>
+  </ul>
+
+  <h3><a name="h3-programs" id="h3-programs">Program

+  <h4><a name="h4-examples" id="h4-examples">Examples</a></h4>
+
+  <p>Along with the library and utilities, improvements were made
+  to the <a href=
+  "https://invisible-island.net/ncurses/ncurses-examples.html">ncurses-examples</a>. Most of
+  this activity aimed at improving the test-packages:</p>
+
+  <ul>
+    <li>
+      <p>add minimal <tt>-h</tt> (usage) and <tt>-V</tt> (version)
+      getopt logic to all ncurses-examples programs.</p>
+    </li>
+
+    <li>
+      <p>fix an error in "@" command in <tt>test/ncurses.c</tt>
+      F-menu</p>
+    </li>
+
+    <li>
+      <p>add curses_trace to ifdef's for <tt>START_TRACE</tt> in
+      <tt>test/test.priv.h</tt></p>
+    </li>
+
+    <li>
+      <p>improve pthread-configuration for test/worm.c</p>
+    </li>
+
+    <li>
+      <p>add <tt>setlocale</tt> call to several test-programs.</p>
+    </li>
+
+    <li>
+      <p>workaround in <tt>test/picsmap.c</tt> for use of floating
+      point for rgb values by ImageMagick 6.9.11, which appears to
+      use the wrong upper limit.</p>
+    </li>
+
+    <li>
+      <p>use static libraries for AdaCurses test-package for
+      Mageia, since no gprbuild package is available.</p>
+    </li>
+
+    <li>
+      <p>install Ada95 sample programs in libexecdir, adding a

+  <h3><a name="h3-bug-fixes" id="h3-bug-fixes">Interesting
+  bug-fixes</a></h3>
+
+  <p>While there were many bugs fixed during development of ncurses
+  6.4, only a few (the reason for this release) were both important
+  and interesting. Most of the bug-fixes were for local issues
+  which did not affect compatibility across releases. Since those
+  are detailed in the <a href=
+  "https://invisible-island.net/ncurses/NEWS.html#t20221231">NEWS</a> file no elaboration is
+  needed here.</p>
+
+  <p>The interesting bugs were those dealing with memory leaks and
+  buffer overflows. Although the utilities are designed for
+  <em>text</em> files (which they do properly), some choose to test
+  them with <strong>non-</strong><em>text</em> files.</p>
+
+  <ul>
+    <li>
+      <p>Text files contain no embedded nulls. Also, they end with
+      a newline. Feeding <strong>tic</strong> non-text files
+      exposed a few cases where the program did not check for those
+      issues. As a result, further processing of the input found
+      limit-checks whose assumptions were invalid.</p>
+    </li>
+
+    <li>
+      <p>Fixing the limit-checks (first) found a problem with
+      <strong>tic</strong> managing the list of strings in a
+      terminal description. In merging two terminal descriptions
+      (i.e., the &ldquo;use=&rdquo; feature), <strong>tic</strong>
+      was not allocating a complete copy. A quick repair for that
+      introduced a memory leak.</p>
+    </li>
+
+    <li>
+      <p>The checks for non-text files are improved (i.e., embedded
+      nulls in the input file will cause <strong>tic</strong> to
+      reject it rather than attempting to process it).</p>
+    </li>
+
+    <li>
+      <p>The string allocations in <strong>tic</strong> are
+      likewise improved.</p>
+    </li>
+  </ul>

+
+  <dl>
+    <dt><tt>--with-abi-version</tt>
+    </dt>
+
+    <dd>
+      <p>add ABI 7 defaults to configure script.</p>

+    </dd>
+  </dl>
+
+  <h3><a name="h3-portability" id="h3-portability">Portability</a></h3>
+
+  <p>Many of the portability changes are implemented via the
+  configure script:</p>
+
+  <ul>
+    <li>
+      <p>amend configure option's auto-search to account for
+      systems where none of the directories known to
+      <em>pkg-config</em> exist</p>
+    </li>
+
+    <li>
+      <p>corrected regex needed for older <em>pkg-config</em> used
+      in Solaris 10</p>
+    </li>
+
+    <li>
+      <p>improve handling of <tt>--with-pkg-config-libdir</tt>
+      option, allowing for the case where either
+      <tt>$PKG_CONFIG_LIBDIR</tt> or the option value has a
+      colon-separated list of directories</p>
+    </li>
+
+    <li>
+      <p>if the <tt>--with-pkg-config-libdir</tt> option is not
+      given, use <tt>${libdir}/pkgconfig</tt> as a default</p>
+    </li>
+
+    <li>
+      <p>improve search-path check for <em>pkg-config</em>, e.g.,
+      for Debian testing which installs <em>pkg-config</em> with
+      architecture-prefixes.</p>
+    </li>
+
+    <li>
+      <p>build-fix for cross-compiling to MingW, conditionally add
+      <tt>-lssp</tt></p>
+    </li>
+
+    <li>
+      <p>improve configure check for <tt>getttynam</tt></p>
+    </li>
+
+    <li>
+      <p>fixes to build with <em>dietlibc</em>:</p>
+
+      <ul>
+        <li>add configure check for <tt>fpathconf</tt></li>
+
+        <li>add configure check for math sine/cosine, needed in
+        test/tclock, and eliminate <tt>pow()</tt> from
+        test/hanoi</li>
+
+        <li>use <tt>wcsnlen</tt> as an alternative to
+        <tt>wmemchr</tt> if it is not found</li>
+      </ul>
+    </li>
+
+    <li>
+      <p>modify configure macro <tt>CF_BUILD_CC</tt> to check if
+      the build-compiler works, rather than that it is different
+      from the cross-compiler, e.g., to accommodate a compiler
+      which can be used for either purpose with different flags</p>
+    </li>
+
+    <li>
+      <p>modify configure/scripts to work around interference by
+      GNU grep 3.8</p>
+    </li>
+  </ul>
+
+  <p>Here are some of the other portability fixes:</p>
+
+  <ul>
+    <li>
+      <p>change <tt>man_db.renames</tt> to template, to handle
+      <em>ncurses*-config</em> script with the
+      <tt>--extra-suffix</tt> configure option.</p>
+    </li>
+
+    <li>
+      <p>update <tt>CF_XOPEN_SOURCE</tt> macro, adding variants
+      &ldquo;gnueabi" and &ldquo;gnueabihf" to get
+      <tt>_DEFAULT_SOURCE</tt> special case, as well as adding GNU
+      libc suffixes for &ldquo;abi64&rdquo;, &ldquo;abin32&rdquo;,
+      &ldquo;x32&rdquo; to distinguish it from other libc
+      flavors.</p>
+    </li>
+
+    <li>
+      <p>work around <em>musl</em>'s nonstandard use of feature
+      test macros by adding a definition for
+      <tt>NCURSES_WIDECHAR</tt> to the generated &ldquo;.pc&rdquo;
+      and <em><tt>*-config</tt></em> files.</p>
+    </li>

+  <span class="main-name">ncurses</span></a></h2>
+
+  <p>The <span class="main-name">ncurses</span> package is fully
+  upward-compatible with SVr4 (System V Release 4) curses:</p>
+
+  <ul>
+    <li>
+      <p>All of the SVr4 calls have been implemented (and are
+      documented).</p>
+    </li>
+
+    <li>
+      <p><span class="main-name">ncurses</span> supports all of the
+      for SVr4 curses features including keyboard mapping, color,
+      forms-drawing with ACS characters, and automatic recognition
+      of keypad and function keys.</p>
+    </li>
+
+    <li>
+      <p><span class="main-name">ncurses</span> provides these SVr4
+      add-on libraries (not part of X/Open Curses):</p>
+
+      <ul>
+        <li>
+          <p>the panels library, supporting a stack of windows with
+          backing store.</p>
+        </li>
+
+        <li>
+          <p>the menus library, supporting a uniform but flexible
+          interface for menu programming.</p>
+        </li>
+
+        <li>
+          <p>the form library, supporting data collection through
+          on-screen forms.</p>
+        </li>
+      </ul>
+    </li>
+
+    <li>
+      <p><span class="main-name">ncurses</span>'s terminal database
+      is fully compatible with that used by SVr4 curses.</p>
+
+      <ul>
+        <li>
+          <p><span class="main-name">ncurses</span> supports
+          user-defined capabilities which it can see, but which are
+          hidden from SVr4 curses applications using the
+          <em>same</em> terminal database.</p>
+        </li>
+
+        <li>
+          <p>It can be optionally configured to match the format
+          used in related systems such as AIX and Tru64.</p>
+        </li>
+
+        <li>
+          <p>Alternatively, <span class="main-name">ncurses</span>
+          can be configured to use hashed databases rather than the
+          directory of files used by SVr4 curses.</p>
+        </li>
+      </ul>
+    </li>
+
+    <li>
+      <p>The <span class="main-name">ncurses</span> utilities have
+      options to allow you to filter terminfo entries for use with
+      less capable <em>curses</em>/<em>terminfo</em> versions such
+      as the HP-UX and AIX ports.</p>
+    </li>
+  </ul>
+
+  <p>The <span class="main-name">ncurses</span> package also has
+  many useful extensions over SVr4:</p>
+
+  <ul>
+    <li>
+      <p>The API is 8-bit clean and base-level conformant with the
+      X/OPEN curses specification, XSI curses (that is, it
+      implements all <em>BASE</em> level features, and most
+      <em>EXTENDED</em> features). It includes many function calls
+      not supported under SVr4 curses (but portability of all calls
+      is documented so you can use the SVr4 subset only).</p>
+    </li>
+
+    <li>
+      <p>Unlike SVr3 curses, <span class="main-name">ncurses</span>
+      can write to the rightmost-bottommost corner of the screen if
+      your terminal has an insert-character capability.</p>
+    </li>
+
+    <li>
+      <p>Ada95 and C++ bindings.</p>
+    </li>
+
+    <li>
+      <p>Support for mouse event reporting with X Window xterm and
+      FreeBSD and OS/2 console windows.</p>
+    </li>
+
+    <li>
+      <p>Extended mouse support via Alessandro Rubini's gpm
+      package.</p>
+    </li>
+
+    <li>
+      <p>The function <code>wresize</code> allows you to resize
+      windows, preserving their data.</p>
+    </li>
+
+    <li>
+      <p>The function <code>use_default_colors</code> allows you to
+      use the terminal's default colors for the default color pair,
+      achieving the effect of transparent colors.</p>
+    </li>
+
+    <li>
+      <p>The functions <code>keyok</code> and
+      <code>define_key</code> allow you to better control the use
+      of function keys, e.g., disabling the <span class=
+      "main-name">ncurses</span> KEY_MOUSE, or by defining more
+      than one control sequence to map to a given key code.</p>
+    </li>
+
+    <li>
+      <p>Support for direct-color terminals, such as modern
+      xterm.</p>
+    </li>
+
+    <li>
+      <p>Support for 256-color terminals, such as modern xterm.</p>
+    </li>
+
+    <li>
+      <p>Support for 16-color terminals, such as <em>aixterm</em>
+      and <em>modern xterm</em>.</p>
+    </li>
+
+    <li>
+      <p>Better cursor-movement optimization. The package now
+      features a cursor-local-movement computation more efficient
+      than either BSD's or System V's.</p>
+    </li>
+
+    <li>
+      <p>Super hardware scrolling support. The screen-update code
+      incorporates a novel, simple, and cheap algorithm that
+      enables it to make optimal use of hardware scrolling,
+      line-insertion, and line-deletion for screen-line movements.
+      This algorithm is more powerful than the 4.4BSD curses
+      <code>quickch</code> routine.</p>
+    </li>
+
+    <li>
+      <p>Real support for terminals with the magic-cookie glitch.
+      The screen-update code will refrain from drawing a highlight
+      if the magic- cookie unattributed spaces required just before
+      the beginning and after the end would step on a non-space
+      character. It will automatically shift highlight boundaries
+      when doing so would make it possible to draw the highlight
+      without changing the visual appearance of the screen.</p>
+    </li>
+
+    <li>
+      <p>It is possible to generate the library with a list of
+      pre-loaded fallback entries linked to it so that it can serve
+      those terminal types even when no terminfo tree or termcap
+      file is accessible (this may be useful for support of
+      screen-oriented programs that must run in single-user
+      mode).</p>
+    </li>
+
+    <li>
+      <p>The <a href="https://invisible-island.net/ncurses/man/tic.1m.html"><span class=
+      "part-name">tic</span></a>/<a href=
+      "https://invisible-island.net/ncurses/man/captoinfo.1m.html">captoinfo</a> utility
+      provided with <span class="main-name">ncurses</span> has the
+      ability to translate many termcaps from the XENIX, IBM and
+      AT&amp;T extension sets.</p>
+    </li>
+
+    <li>
+      <p>A BSD-like <a href=
+      "https://invisible-island.net/ncurses/man/tset.1.html"><span class=
+      "part-name">tset</span></a> utility is provided.</p>
+    </li>
+
+    <li>
+      <p>The <span class="main-name">ncurses</span> library and
+      utilities will automatically read terminfo entries from
+      $HOME/.terminfo if it exists, and compile to that directory
+      if it exists and the user has no write access to the system
+      directory. This feature makes it easier for users to have
+      personal terminfo entries without giving up access to the
+      system terminfo directory.</p>
+    </li>
+
+    <li>
+      <p>You may specify a path of directories to search for
+      compiled descriptions with the environment variable
+      TERMINFO_DIRS (this generalizes the feature provided by
+      TERMINFO under stock System V.)</p>
+    </li>
+
+    <li>
+      <p>In terminfo source files, use capabilities may refer not
+      just to other entries in the same source file (as in System
+      V) but also to compiled entries in either the system terminfo
+      directory or the user's $HOME/.terminfo directory.</p>
+    </li>
+
+    <li>
+      <p>The table-of-entries utility <a href=
+      "https://invisible-island.net/ncurses/man/toe.1m.html"><span class=
+      "part-name">toe</span></a> makes it easy for users to see
+      exactly what terminal types are available on the system.</p>
+    </li>
+
+    <li>
+      <p>The library meets the XSI requirement that every macro
+      entry point has a corresponding function which may be linked
+      (and will be prototype-checked) if the macro definition is
+      disabled with <code>#undef</code>.</p>
+    </li>
+
+    <li>
+      <p>Extensive documentation is provided (see the <em><a href=

+
+  <h2><a name="abstract" id="abstract">Abstract</a></h2>
+
+  <p>This document is a hacker's tour of the
+  <strong>ncurses</strong> library and utilities. It discusses
+  design philosophy, implementation methods, and the conventions
+  used for coding and documentation. It is recommended reading for
+  anyone who is interested in porting, extending or improving the
+  package.</p>
+
+  <h2><a name="objective" id="objective">Objective of the
+  Package</a></h2>
+
+  <p>The objective of the <strong>ncurses</strong> package is to
+  provide a free software API for character-cell terminals and
+  terminal emulators with the following characteristics:</p>
+
+  <ul>
+    <li>Source-compatible with historical curses implementations
+    (including the original BSD curses and System V curses.</li>
+
+    <li>Conformant with the XSI Curses standard issued as part of
+    XPG4 by X/Open.</li>
+
+    <li>High-quality &mdash; stable and reliable code, wide
+    portability, good packaging, superior documentation.</li>
+
+    <li>Featureful &mdash; should eliminate as much of the drudgery
+    of C interface programming as possible, freeing programmers to
+    think at a higher level of design.</li>
+  </ul>
+
+  <p>These objectives are in priority order. So, for example,
+  source compatibility with older version must trump featurefulness
+  &mdash; we cannot add features if it means breaking the portion
+  of the API corresponding to historical curses versions.</p>
+
+  <h3><a name="whysvr4" id="whysvr4">Why System V Curses?</a></h3>
+
+  <p>We used System V curses as a model, reverse-engineering their
+  API, in order to fulfill the first two objectives.</p>
+
+  <p>System V curses implementations can support BSD curses
+  programs with just a recompilation, so by capturing the System V
+  API we also capture BSD's.</p>
+
+  <p>More importantly for the future, the XSI Curses standard
+  issued by X/Open is explicitly and closely modeled on System V.
+  So conformance with System V took us most of the way to
+  base-level XSI conformance.</p>
+
+  <h3><a name="extensions" id="extensions">How to Design
+  Extensions</a></h3>
+
+  <p>The third objective (standards conformance) requires that it
+  be easy to condition source code using <strong>ncurses</strong>
+  so that the absence of nonstandard extensions does not break the
+  code.</p>
+
+  <p>Accordingly, we have a policy of associating with each
+  nonstandard extension a feature macro, so that ncurses client
+  code can use this macro to condition in or out the code that
+  requires the <strong>ncurses</strong> extension.</p>
+
+  <p>For example, there is a macro
+  <code>NCURSES_MOUSE_VERSION</code> which XSI Curses does not
+  define, but which is defined in the <strong>ncurses</strong>
+  library header. You can use this to condition the calls to the
+  mouse API calls.</p>
+
+  <h2><a name="portability" id="portability">Portability and
+  Configuration</a></h2>
+
+  <p>Code written for <strong>ncurses</strong> may assume an
+  ANSI-standard C compiler and POSIX-compatible OS interface. It
+  may also assume the presence of a System-V-compatible
+  <em>select(2)</em> call.</p>
+
+  <p>We encourage (but do not require) developers to make the code
+  friendly to less-capable UNIX environments wherever possible.</p>
+
+  <p>We encourage developers to support OS-specific optimizations
+  and methods not available under POSIX/ANSI, provided only
+  that:</p>
+
+  <ul>
+    <li>All such code is properly conditioned so the build process
+    does not attempt to compile it under a plain ANSI/POSIX
+    environment.</li>
+
+    <li>Adding such implementation methods does not introduce
+    incompatibilities in the <strong>ncurses</strong> API between
+    platforms.</li>
+  </ul>
+
+  <p>We use GNU <code>autoconf(1)</code> as a tool to deal with
+  portability issues. The right way to leverage an OS-specific
+  feature is to modify the autoconf specification files
+  (configure.in and aclocal.m4) to set up a new feature macro,
+  which you then use to condition your code.</p>
+
+  <h2><a name="documentation" id="documentation">Documentation
+  Conventions</a></h2>
+
+  <p>There are three kinds of documentation associated with this
+  package. Each has a different preferred format:</p>
+
+  <ul>
+    <li>Package-internal files (README, INSTALL, TO-DO etc.)</li>
+
+    <li>Manual pages.</li>
+
+    <li>Everything else (i.e., narrative documentation).</li>
+  </ul>
+
+  <p>Our conventions are simple:</p>
+
+  <ol>
+    <li><strong>Maintain package-internal files in plain
+    text.</strong> The expected viewer for them is <em>more(1)</em> or
+    an editor window; there is no point in elaborate mark-up.</li>
+
+    <li><strong>Mark up manual pages in the man macros.</strong>
+    These have to be viewable through traditional <em>man(1)</em>
+    programs.</li>
+
+    <li><strong>Write everything else in HTML.</strong>
+    </li>
+  </ol>
+
+  <p>When in doubt, HTMLize a master and use <em>lynx(1)</em> to
+  generate plain ASCII (as we do for the announcement
+  document).</p>
+
+  <p>The reason for choosing HTML is that it is (a) well-adapted
+  for on-line browsing through viewers that are everywhere; (b)
+  more easily readable as plain text than most other mark-ups, if
+  you do not have a viewer; and (c) carries enough information that
+  you can generate a nice-looking printed version from it. Also, of
+  course, it make exporting things like the announcement document
+  to WWW pretty trivial.</p>
+
+  <h2><a name="bugtrack" id="bugtrack">How to Report Bugs</a></h2>
+
+  <p>The <a name="bugreport" id="bugreport">reporting address for
+  bugs</a> is <a href=
+  "mailto:bug-ncurses@gnu.org">bug-ncurses@gnu.org</a>. This is a
+  majordomo list; to join, write to
+  <code>bug-ncurses-request@gnu.org</code> with a message
+  containing the line:</p>
+
+  <pre class="code-block">
+             subscribe &lt;name&gt;@&lt;host.domain&gt;
+</pre>
+  <p>The <code>ncurses</code> code is maintained by a small group
+  of volunteers. While we try our best to fix bugs promptly, we
+  simply do not have a lot of hours to spend on elementary
+  hand-holding. We rely on intelligent cooperation from our users.
+  If you think you have found a bug in <code>ncurses</code>, there
+  are some steps you can take before contacting us that will help
+  get the bug fixed quickly.</p>
+
+  <p>In order to use our bug-fixing time efficiently, we put people
+  who show us they have taken these steps at the head of our queue.
+  This means that if you do not, you will probably end up at the
+  tail end and have to wait a while.</p>
+
+  <ol>
+    <li><p>Develop a recipe to reproduce the bug.
+      <p>Bugs we can reproduce are likely to be fixed very quickly,
+      often within days. The most effective single thing you can do
+      to get a quick fix is develop a way we can duplicate the bad
+      behavior &mdash; ideally, by giving us source for a small,
+      portable test program that breaks the library. (Even better
+      is a keystroke recipe using one of the test programs provided
+      with the distribution.)</p>
+    </li>
+
+    <li><p>Try to reproduce the bug on a different terminal type.
+      <p>In our experience, most of the behaviors people report as
+      library bugs are actually due to subtle problems in terminal
+      descriptions. This is especially likely to be true if you are
+      using a traditional asynchronous terminal or PC-based
+      terminal emulator, rather than xterm or a UNIX console
+      entry.</p>
+
+      <p>It is therefore extremely helpful if you can tell us
+      whether or not your problem reproduces on other terminal
+      types. Usually you will have both a console type and xterm
+      available; please tell us whether or not your bug reproduces
+      on both.</p>
+
+      <p>If you have xterm available, it is also good to collect
+      xterm reports for different window sizes. This is especially
+      true if you normally use an unusual xterm window size &mdash;
+      a surprising number of the bugs we have seen are either
+      triggered or masked by these.</p>
+    </li>
+
+    <li><p>Generate and examine a trace file for the broken behavior.
+      <p>Recompile your program with the debugging versions of the
+      libraries. Insert a <code>trace()</code> call with the
+      argument set to <code>TRACE_UPDATE</code>. (See <a href=
+      "ncurses-intro.html#debugging">"Writing Programs with
+      NCURSES"</a> for details on trace levels.) Reproduce your
+      bug, then look at the trace file to see what the library was
+      actually doing.</p>
+
+      <p>Another frequent cause of apparent bugs is application
+      coding errors that cause the wrong things to be put on the
+      virtual screen. Looking at the virtual-screen dumps in the
+      trace file will tell you immediately if this is happening,
+      and save you from the possible embarrassment of being told
+      that the bug is in your code and is your problem rather than
+      ours.</p>
+
+      <p>If the virtual-screen dumps look correct but the bug
+      persists, it is possible to crank up the trace level to give
+      more and more information about the library's update actions
+      and the control sequences it issues to perform them. The test
+      directory of the distribution contains a tool for digesting
+      these logs to make them less tedious to wade through.</p>
+
+      <p>Often you will find terminfo problems at this stage by
+      noticing that the escape sequences put out for various
+      capabilities are wrong. If not, you are likely to learn
+      enough to be able to characterize any bug in the
+      screen-update logic quite exactly.</p>
+    </li>
+
+    <li><p>Report details and symptoms, not just interpretations.
+      <p>If you do the preceding two steps, it is very likely that
+      you will discover the nature of the problem yourself and be
+      able to send us a fix. This will create happy feelings all
+      around and earn you good karma for the first time you run
+      into a bug you really cannot characterize and fix
+      yourself.</p>
+
+      <p>If you are still stuck, at least you will know what to
+      tell us. Remember, we need details. If you guess about what
+      is safe to leave out, you are too likely to be wrong.</p>
+
+      <p>If your bug produces a bad update, include a trace file.
+      Try to make the trace at the <em>least</em> voluminous level
+      that pins down the bug. Logs that have been through
+      tracemunch are OK, it does not throw away any information
+      (actually they are better than un-munched ones because they
+      are easier to read).</p>
+
+      <p>If your bug produces a core-dump, please include a
+      symbolic stack trace generated by gdb(1) or your local
+      equivalent.</p>
+
+      <p>Tell us about every terminal on which you have reproduced
+      the bug &mdash; and every terminal on which you cannot.
+      Ideally, send us terminfo sources for all of these (yours
+      might differ from ours).</p>
+
+      <p>Include your ncurses version and your OS/machine type, of
+      course! You can find your ncurses version in the
+      <code>curses.h</code> file.</p>
+    </li>
+  </ol>
+
+  <p>If your problem smells like a logic error or in cursor
+  movement or scrolling or a bad capability, there are a couple of
+  tiny test frames for the library algorithms in the progs
+  directory that may help you isolate it. These are not part of the
+  normal build, but do have their own make productions.</p>
+
+  <p>The most important of these is <code>mvcur</code>, a test
+  frame for the cursor-movement optimization code. With this
+  program, you can see directly what control sequences will be
+  emitted for any given cursor movement or scroll/insert/delete
+  operations. If you think you have got a bad capability
+  identified, you can disable it and test again. The program is
+  command-driven and has on-line help.</p>
+
+  <p>If you think the vertical-scroll optimization is broken, or
+  just want to understand how it works better, build
+  <code>hashmap</code> and read the header comments of
+  <code>hardscroll.c</code> and <code>hashmap.c</code>; then try it
+  out. You can also test the hardware-scrolling optimization
+  separately with <code>hardscroll</code>.</p>

+
+  <p>There is another group of files that do direct I/O via

+

+
+  <p>Finally, there is a group of files that is actually most of
+  the terminfo compiler. The reason this code lives in the

+
+  <blockquote>

+
+  <h3><a name="engine" id="engine">The Engine Room</a></h3>
+
+  <h4><a name="input" id="input">Keyboard Input</a></h4>
+
+  <p>All <code>ncurses</code> input funnels through the function
+  <code>wgetch()</code>, defined in <code>lib_getch.c</code>. This
+  function is tricky; it has to poll for keyboard and mouse events
+  and do a running match of incoming input against the set of
+  defined special keys.</p>
+
+  <p>The central data structure in this module is a FIFO queue,
+  used to match multiple-character input sequences against
+  special-key capabilities; also to implement pushback via
+  <code>ungetch()</code>.</p>
+
+  <p>The <code>wgetch()</code> code distinguishes between function
+  key sequences and the same sequences typed manually by doing a
+  timed wait after each input character that could lead a function
+  key sequence. If the entire sequence takes less than 1 second, it
+  is assumed to have been generated by a function key press.</p>
+
+  <p>Hackers bruised by previous encounters with variant
+  <code>select(2)</code> calls may find the code in
+  <code>lib_twait.c</code> interesting. It deals with the problem
+  that some BSD selects do not return a reliable time-left value.
+  The function <code>timed_wait()</code> effectively simulates a
+  System V select.</p>
+
+  <h4><a name="mouse" id="mouse">Mouse Events</a></h4>
+
+  <p>If the mouse interface is active, <code>wgetch()</code> polls
+  for mouse events each call, before it goes to the keyboard for
+  input. It is up to <code>lib_mouse.c</code> how the polling is
+  accomplished; it may vary for different devices.</p>
+
+  <p>Under xterm, however, mouse event notifications come in via
+  the keyboard input stream. They are recognized by having the
+  <strong>kmous</strong> capability as a prefix. This is kind of
+  klugey, but trying to wire in recognition of a mouse key prefix
+  without going through the function-key machinery would be just
+  too painful, and this turns out to imply having the prefix
+  somewhere in the function-key capabilities at terminal-type
+  initialization.</p>
+
+  <p>This kluge only works because <strong>kmous</strong> is not
+  actually used by any historic terminal type or curses
+  implementation we know of. Best guess is it is a relic of some
+  forgotten experiment in-house at Bell Labs that did not leave any
+  traces in the publicly-distributed System V terminfo files. If
+  System V or XPG4 ever gets serious about using it again, this
+  kluge may have to change.</p>
+
+  <p>Here are some more details about mouse event handling:</p>
+
+  <p>The <code>lib_mouse()</code> code is logically split into a
+  lower level that accepts event reports in a device-dependent
+  format and an upper level that parses mouse gestures and filters
+  events. The mediating data structure is a circular queue of event
+  structures.</p>
+
+  <p>Functionally, the lower level's job is to pick up primitive
+  events and put them on the circular queue. This can happen in one
+  of two ways: either (a) <code>_nc_mouse_event()</code> detects a
+  series of incoming mouse reports and queues them, or (b) code in
+  <code>lib_getch.c</code> detects the <strong>kmous</strong>
+  prefix in the keyboard input stream and calls _nc_mouse_inline to
+  queue up a series of adjacent mouse reports.</p>
+
+  <p>In either case, <code>_nc_mouse_parse()</code> should be
+  called after the series is accepted to parse the digested mouse
+  reports (low-level events) into a gesture (a high-level or
+  composite event).</p>
+
+  <h4><a name="output" id="output">Output and Screen Updating</a></h4>
+
+  <p>With the single exception of character echoes during a
+  <code>wgetnstr()</code> call (which simulates cooked-mode line
+  editing in an ncurses window), the library normally does all its
+  output at refresh time.</p>
+
+  <p>The main job is to go from the current state of the screen (as
+  represented in the <code>curscr</code> window structure) to the
+  desired new state (as represented in the <code>newscr</code>
+  window structure), while doing as little I/O as possible.</p>
+
+  <p>The brains of this operation are the modules
+  <code>hashmap.c</code>, <code>hardscroll.c</code> and
+  <code>lib_doupdate.c</code>; the latter two use
+  <code>lib_mvcur.c</code>. Essentially, what happens looks like
+  this:</p>
+
+  <ul>
+    <li>
+      <p>The <code>hashmap.c</code> module tries to detect vertical
+      motion changes between the real and virtual screens. This
+      information is represented by the oldindex members in the
+      newscr structure. These are modified by vertical-motion and
+      clear operations, and both are re-initialized after each
+      update. To this change-journalling information, the hashmap
+      code adds deductions made using a modified Heckel algorithm
+      on hash values generated from the line contents.</p>
+    </li>
+
+    <li>
+      <p>The <code>hardscroll.c</code> module computes an optimum
+      set of scroll, insertion, and deletion operations to make the
+      indices match. It calls <code>_nc_mvcur_scrolln()</code> in
+      <code>lib_mvcur.c</code> to do those motions.</p>
+    </li>
+
+    <li>
+      <p>Then <code>lib_doupdate.c</code> goes to work. Its job is
+      to do line-by-line transformations of <code>curscr</code>
+      lines to <code>newscr</code> lines. Its main tool is the
+      routine <code>mvcur()</code> in <code>lib_mvcur.c</code>.
+      This routine does cursor-movement optimization, attempting to
+      get from given screen location A to given location B in the
+      fewest output characters possible.</p>
+    </li>
+  </ul>
+
+  <p>If you want to work on screen optimizations, you should use
+  the fact that (in the trace-enabled version of the library)
+  enabling the <code>TRACE_TIMES</code> trace level causes a report
+  to be emitted after each screen update giving the elapsed time
+  and a count of characters emitted during the update. You can use
+  this to tell when an update optimization improves efficiency.</p>
+
+  <p>In the trace-enabled version of the library, it is also
+  possible to disable and re-enable various optimizations at
+  runtime by tweaking the variable
+  <code>_nc_optimize_enable</code>. See the file
+  <code>include/curses.h.in</code> for mask values, near the
+  end.</p>
+
+  <h2><a name="fmnote" id="fmnote">The Forms and Menu Libraries</a></h2>
+
+  <p>The forms and menu libraries should work reliably in any
+  environment you can port ncurses to. The only portability issue
+  anywhere in them is what flavor of regular expressions the
+  built-in form field type TYPE_REGEXP will recognize.</p>
+
+  <p>The configuration code prefers the POSIX regex facility,
+  modeled on System V's, but will settle for BSD regexps if the
+  former is not available.</p>
+
+  <p>Historical note: the panels code was written primarily to
+  assist in porting u386mon 2.0 (comp.sources.misc v14i001-4) to
+  systems lacking panels support; u386mon 2.10 and beyond use it.
+  This version has been slightly cleaned up for
+  <code>ncurses</code>.</p>
+
+  <h2><a name="tic" id="tic">A Tour of the Terminfo Compiler</a></h2>
+
+  <p>The <strong>ncurses</strong> implementation of
+  <strong>tic</strong> is rather complex internally; it has to do a
+  trying combination of missions. This starts with the fact that,
+  in addition to its normal duty of compiling terminfo sources into
+  loadable terminfo binaries, it has to be able to handle termcap
+  syntax and compile that too into terminfo entries.</p>
+
+  <p>The implementation therefore starts with a table-driven,
+  dual-mode lexical analyzer (in <code>comp_scan.c</code>). The
+  lexer chooses its mode (termcap or terminfo) based on the first
+  &ldquo;,&rdquo; or &ldquo;:&rdquo; it finds in each entry. The
+  lexer does all the work of recognizing capability names and
+  values; the grammar above it is trivial, just "parse entries till
+  you run out of file".</p>
+
+  <h3><a name="nonuse" id="nonuse">Translation of
+  Non-<strong>use</strong> Capabilities</a></h3>
+
+  <p>Translation of most things besides <strong>use</strong>
+  capabilities is pretty straightforward. The lexical analyzer's
+  tokenizer hands each capability name to a hash function, which
+  drives a table lookup. The table entry yields an index which is
+  used to look up the token type in another table, and controls
+  interpretation of the value.</p>
+
+  <p>One possibly interesting aspect of the implementation is the
+  way the compiler tables are initialized. All the tables are
+  generated by various awk/sed/sh scripts from a master table
+  <code>include/Caps</code>; these scripts actually write C
+  initializers which are linked to the compiler. Furthermore, the
+  hash table is generated in the same way, so it doesn't have to be
+  generated at compiler startup time (another benefit of this
+  organization is that the hash table can be in shareable text
+  space).</p>
+
+  <p>Thus, adding a new capability is usually pretty trivial, just
+  a matter of adding one line to the <code>include/Caps</code>
+  file. We will have more to say about this in the section on
+  <a href="#translation">Source-Form Translation</a>.</p>
+
+  <h3><a name="uses" id="uses">Use Capability Resolution</a></h3>
+
+  <p>The background problem that makes <strong>tic</strong> tricky
+  is not the capability translation itself, it is the resolution of
+  <strong>use</strong> capabilities. Older versions would not
+  handle forward <strong>use</strong> references for this reason
+  (that is, a using terminal always had to follow its use target in
+  the source file). By doing this, they got away with a simple
+  implementation tactic; compile everything as it blows by, then
+  resolve uses from compiled entries.</p>
+
+  <p>This will not do for <strong>ncurses</strong>. The problem is
+  that that the whole compilation process has to be embeddable in
+  the <strong>ncurses</strong> library so that it can be called by
+  the startup code to translate termcap entries on the fly. The
+  embedded version cannot go promiscuously writing everything it
+  translates out to disk &mdash; for one thing, it will typically
+  be running with non-root permissions.</p>
+
+  <p>So our <strong>tic</strong> is designed to parse an entire
+  terminfo file into a doubly-linked circular list of entry
+  structures in-core, and then do <strong>use</strong> resolution
+  in-memory before writing everything out. This design has other
+  advantages: it makes forward and back use-references equally easy
+  (so we get the latter for free), and it makes checking for name
+  collisions before they are written out easy to do.</p>
+
+  <p>And this is exactly how the embedded version works. But the
+  stand-alone user-accessible version of <strong>tic</strong>
+  partly reverts to the historical strategy; it writes to disk (not
+  keeping in core) any entry with no <strong>use</strong>
+  references.</p>
+
+  <p>This is strictly a core-economy kluge, implemented because the
+  terminfo master file is large enough that some core-poor systems
+  swap like crazy when you compile it all in memory...there have
+  been reports of this process taking <strong>three hours</strong>,
+  rather than the twenty seconds or less typical on the author's
+  development box.</p>
+
+  <p>So. The executable <strong>tic</strong> passes the
+  entry-parser a hook that <em>immediately</em> writes out the
+  referenced entry if it has no use capabilities. The compiler main
+  loop refrains from adding the entry to the in-core list when this
+  hook fires. If some other entry later needs to reference an entry
+  that got written immediately, that is OK; the resolution code
+  will fetch it off disk when it cannot find it in core.</p>
+
+  <p>Name collisions will still be detected, just not as cleanly.
+  The <code>write_entry()</code> code complains before overwriting
+  an entry that postdates the time of <strong>tic</strong>'s first
+  call to <code>write_entry()</code>, Thus it will complain about
+  overwriting entries newly made during the <strong>tic</strong>
+  run, but not about overwriting ones that predate it.</p>
+
+  <h3><a name="translation" id="translation">Source-Form
+  Translation</a></h3>
+
+  <p>Another use of <strong>tic</strong> is to do source
+  translation between various termcap and terminfo formats. There
+  are more variants out there than you might think; the ones we
+  know about are described in the <strong>captoinfo(1)</strong>
+  manual page.</p>
+
+  <p>The translation output code (<code>dump_entry()</code> in
+  <code>ncurses/dump_entry.c</code>) is shared with the
+  <strong>infocmp(1)</strong> utility. It takes the same internal
+  representation used to generate the binary form and dumps it to
+  standard output in a specified format.</p>
+
+  <p>The <code>include/Caps</code> file has a header comment
+  describing ways you can specify source translations for
+  nonstandard capabilities just by altering the master table. It is
+  possible to set up capability aliasing or tell the compiler to
+  plain ignore a given capability without writing any C code at
+  all.</p>
+
+  <p>For circumstances where you need to do algorithmic
+  translation, there are functions in <code>parse_entry.c</code>
+  called after the parse of each entry that are specifically
+  intended to encapsulate such translations. This, for example, is
+  where the AIX <strong>box1</strong> capability get translated to
+  an <strong>acsc</strong> string.</p>
+
+  <h2><a name="utils" id="utils">Other Utilities</a></h2>
+
+  <p>The <strong>infocmp</strong> utility is just a wrapper around
+  the same entry-dumping code used by <strong>tic</strong> for
+  source translation. Perhaps the one interesting aspect of the
+  code is the use of a predicate function passed in to
+  <code>dump_entry()</code> to control which capabilities are
+  dumped. This is necessary in order to handle both the ordinary
+  De-compilation case and entry difference reporting.</p>
+
+  <p>The <strong>tput</strong> and <strong>clear</strong> utilities
+  just do an entry load followed by a <code>tputs()</code> of a
+  selected capability.</p>
+
+  <h2><a name="style" id="style">Style Tips for Developers</a></h2>
+
+  <p>See the TO-DO file in the top-level directory of the source
+  distribution for additions that would be particularly useful.</p>
+
+  <p>The prefix <code>_nc_</code> should be used on library public
+  functions that are not part of the curses API in order to prevent
+  pollution of the application namespace. If you have to add to or
+  modify the function prototypes in curses.h.in, read
+  ncurses/MKlib_gen.sh first so you can avoid breaking XSI
+  conformance. Please join the ncurses mailing list. See the
+  INSTALL file in the top level of the distribution for details on
+  the list.</p>
+
+  <p>Look for the string <code>FIXME</code> in source files to tag
+  minor bugs and potential problems that could use fixing.</p>
+
+  <p>Do not try to auto-detect OS features in the main body of the
+  C code. That is the job of the configuration system.</p>
+
+  <p>To hold down complexity, do make your code data-driven.
+  Especially, if you can drive logic from a table filtered out of
+  <code>include/Caps</code>, do it. If you find you need to augment
+  the data in that file in order to generate the proper table, that
+  is still preferable to ad-hoc code &mdash; that is why the fifth
+  field (flags) is there.</p>
+
+  <p>Have fun!</p>
+

+       determine how to clear the screen.
+
+       <STRONG>clear</STRONG>  writes  to  the  standard output.  You can redirect the standard

+            and <STRONG>COLUMNS</STRONG> will also be ignored.

+
+
+</PRE><H2><a name="h2-HISTORY">HISTORY</a></H2><PRE>
+       A  <STRONG>clear</STRONG>  command  appeared  in 2.79BSD dated February 24, 1979.  Later
+       that was provided in Unix 8th edition (1985).
+
+       AT&amp;T adapted a different BSD program  (<STRONG>tset</STRONG>)  to  make  a  new  command
+       (<STRONG>tput</STRONG>),  and used this to replace the <STRONG>clear</STRONG> command with a shell script
+       which calls <STRONG>tput</STRONG> <STRONG>clear</STRONG>, e.g.,
+
+           /usr/bin/tput ${1:+-T$1} clear 2&gt; /dev/null
+           exit
+
+       In 1989, when Keith Bostic revised the BSD  <STRONG>tput</STRONG>  command  to  make  it
+       similar  to  the  AT&amp;T  <STRONG>tput</STRONG>,  he  added  a  shell script for the <STRONG>clear</STRONG>
+       command:
+
+           exec tput clear
+
+       The remainder of the script in each case is a copyright notice.
+
+       The ncurses <STRONG>clear</STRONG> command began in 1995 by adapting  the  original  BSD
+       <STRONG>clear</STRONG> command (with terminfo, of course).
+
+       The <STRONG>E3</STRONG> extension came later:
+
+       <STRONG>o</STRONG>   In  June  1999, <STRONG>xterm</STRONG> provided an extension to the standard control
+           sequence for clearing the screen.  Rather than  clearing  just  the
+           visible part of the screen using
+
+               printf '\033[2J'
+
+           one could clear the <EM>scrollback</EM> using
+
+               printf '\033[<STRONG>3</STRONG>J'
+
+           This  is  documented  in  <EM>XTerm</EM>  <EM>Control</EM>  <EM>Sequences</EM>  as  a  feature
+           originating with <STRONG>xterm</STRONG>.
+
+       <STRONG>o</STRONG>   A few other terminal developers adopted the feature, e.g., PuTTY in
+           2006.
+
+       <STRONG>o</STRONG>   In  April  2011, a Red Hat developer submitted a patch to the Linux
+           kernel, modifying its console driver to do  the  same  thing.   The
+           Linux  change,  part  of  the  3.0  release, did not mention <STRONG>xterm</STRONG>,
+           although it was cited in the Red Hat bug report (#683733) which led
+           to the change.
+
+       <STRONG>o</STRONG>   Again,  a  few  other terminal developers adopted the feature.  But
+           the next relevant step was a change to the <STRONG>clear</STRONG> program in 2013 to
+           incorporate this extension.
+
+       <STRONG>o</STRONG>   In  2013,  the <STRONG>E3</STRONG> extension was overlooked in <STRONG>tput</STRONG> with the "clear"
+           parameter.  That was addressed in  2016  by  reorganizing  <STRONG>tput</STRONG>  to
+           share its logic with <STRONG>clear</STRONG> and <STRONG>tset</STRONG>.
+

+       Neither IEEE Std 1003.1/The Open  Group  Base  Specifications  Issue  7
+       (POSIX.1-2008) nor X/Open Curses Issue 7 documents tset or reset.
+
+       The latter documents <STRONG>tput</STRONG>, which could be used to replace this  utility
+       either  via  a shell script or by an alias (such as a symbolic link) to
+       run <STRONG>tput</STRONG> as <STRONG>clear</STRONG>.

+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       All routines return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.
+
+       X/Open does not  define  any  error  conditions.   This  implementation
+       returns an error
+
+       <STRONG>o</STRONG>   if the window pointer is null or
+
+       <STRONG>o</STRONG>   if it is not possible to add a complete character in the window.
+
+       The latter may be due to different causes:
+
+       <STRONG>o</STRONG>   If  <STRONG>scrollok</STRONG> is not enabled, writing a character at the lower right
+           margin succeeds.  However, an error is returned because it  is  not
+           possible to wrap to a new line
+
+       <STRONG>o</STRONG>   If  an error is detected when converting a multibyte character to a
+           sequence of bytes, or if it is not  possible  to  add  all  of  the
+           resulting bytes in the window, an error is returned.
+
+       Functions  with  a  "mv"  prefix  first perform a cursor movement using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.

+       All  of these functions are described in the XSI Curses standard, Issue
+       4.  The defaults specified for line-drawing  characters  apply  in  the
+       POSIX locale.
+
+       X/Open  Curses  makes it clear that the WACS_ symbols should be defined
+       as a pointer to <STRONG>cchar_t</STRONG> data, e.g., in the discussion of <STRONG>border_set</STRONG>.  A
+       few implementations are problematic:
+
+       <STRONG>o</STRONG>   NetBSD curses defines the symbols as a <STRONG>wchar_t</STRONG> within a <STRONG>cchar_t</STRONG>.
+
+       <STRONG>o</STRONG>   HPUX curses equates some of the <STRONG>ACS_</STRONG> symbols to the analogous <STRONG>WACS_</STRONG>
+           symbols  as  if  the  <STRONG>ACS_</STRONG>  symbols  were  wide  characters.    The
+           misdefined  symbols  are the arrows and other symbols which are not
+           used for line-drawing.
+
+       X/Open Curses does not define symbols for thick- or double-lines.  SVr4
+       curses  implementations  defined their line-drawing symbols in terms of
+       intermediate  symbols.   This  implementation  extends  those  symbols,
+       providing new definitions which are not in the SVr4 implementations.
+
+       Not  all  Unicode-capable  terminals  provide  support  for VT100-style
+       alternate character  sets  (i.e.,  the  <STRONG>acsc</STRONG>  capability),  with  their
+       corresponding  line-drawing  characters.  X/Open Curses did not address
+       the  aspect  of  integrating  Unicode  with  line-drawing   characters.
+       Existing  implementations  of Unix curses (AIX, HPUX, Solaris) use only
+       the <STRONG>acsc</STRONG> character-mapping to provide this feature.  As a result, those
+       implementations  can  only  use  single-byte  line-drawing  characters.
+       Ncurses 5.3 (2002) provided a table of Unicode values  to  solve  these
+       problems.  NetBSD curses incorporated that table in 2010.
+
+       In  this  implementation,  the  Unicode  values are used instead of the
+       terminal description's <STRONG>acsc</STRONG> mapping as discussed in <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG> for the
+       environment  variable  <STRONG>NCURSES_NO_UTF8_ACS</STRONG>.   In contrast, for the same
+       cases, the line-drawing characters described in <STRONG><A HREF="curs_addch.3x.html">curs_addch(3x)</A></STRONG> will use
+       only the ASCII default values.
+
+       Having  Unicode available does not solve all of the problems with line-
+       drawing for curses:
+
+       <STRONG>o</STRONG>   The closest Unicode equivalents to the VT100 graphics  <EM>S1</EM>,  <EM>S3</EM>,  <EM>S7</EM>
+           and  <EM>S9</EM> frequently are not displayed at the regular intervals which
+           the terminal used.
+
+       <STRONG>o</STRONG>   The <EM>lantern</EM> is a special case.  It originated with  the  AT&amp;T  4410
+           terminal  in the early 1980s.  There is no accessible documentation
+           depicting the lantern symbol on the AT&amp;T terminal.
+
+           Lacking documentation, most readers assume that a <EM>storm</EM> <EM>lantern</EM> was
+           intended.  But there are several possibilities, all with problems.
+
+           Unicode  6.0  (2010)  does provide two lantern symbols: U+1F383 and
+           U+1F3EE.  Those were not available  in  2002,  and  are  irrelevant
+           since  they  lie  outside the BMP and as a result are not generally
+           available in terminals.  They are not storm lanterns, in any case.
+
+           Most <EM>storm</EM> <EM>lanterns</EM> have a tapering glass chimney (to guard against
+           tipping); some have a wire grid protecting the chimney.
+
+           For  the  tapering  appearance,   U+2603 was adequate.  In use on a
+           terminal, no one can tell what the image represents.  Unicode calls
+           it a snowman.
+
+           Others have suggested these alternatives: &lt;section&gt; U+00A7 (section
+           mark), &lt;Theta&gt; U+0398 (theta), &lt;Phi&gt; U+03A6 (phi),  &lt;delta&gt;  U+03B4
+           (delta),  U+2327 (x in a rectangle),  U+256C (forms double vertical
+           and horizontal), and  U+2612 (ballot box with x).

+       These  functions copy the (null-terminated) array of complex characters
+       <EM>wchstr</EM> into the window image structure starting at the  current  cursor
+       position.   The four functions with <EM>n</EM> as the last argument copy at most
+       <EM>n</EM> elements, but no more than will fit on the line.  If  <STRONG>n</STRONG>=<STRONG>-1</STRONG>  then  the
+       whole  array  is  copied, to the maximum number of characters that will
+       fit on the line.
+
+       The window cursor is <EM>not</EM> advanced.  These functions  work  faster  than
+       <STRONG>waddnstr</STRONG>.  On the other hand:
+
+       <STRONG>o</STRONG>   they  do  not perform checking (such as for the newline, backspace,
+           or carriage return characters),
+
+       <STRONG>o</STRONG>   they do not advance the current cursor position,
+
+       <STRONG>o</STRONG>   they do not expand other control characters to ^-escapes, and
+
+       <STRONG>o</STRONG>   they truncate the string if it crosses  the  right  margin,  rather
+           than wrapping it around to the new line.
+
+       These  functions  end  successfully  on encountering a null <STRONG>cchar_t</STRONG>, or
+       when they have filled the current line.  If a complex character  cannot
+       completely  fit  at  the end of the current line, the remaining columns
+       are filled with the background character and rendition.

+       The <STRONG>addch</STRONG>, <STRONG>waddch</STRONG>, <STRONG>mvaddch</STRONG> and <STRONG>mvwaddch</STRONG> routines put the  character  <EM>ch</EM>
+       into  the  given  window  at its current window position, which is then
+       advanced.  They are  analogous  to  <STRONG>putchar(3)</STRONG>  in  <STRONG>stdio(3)</STRONG>.   If  the
+       advance is at the right margin:
+
+       <STRONG>o</STRONG>   The cursor automatically wraps to the beginning of the next line.
+
+       <STRONG>o</STRONG>   At  the  bottom of the current scrolling region, and if <STRONG>scrollok</STRONG> is
+           enabled, the scrolling region is scrolled up one line.
+
+       <STRONG>o</STRONG>   If <STRONG>scrollok</STRONG> is not enabled, writing a character at the lower  right
+           margin  succeeds.   However, an error is returned because it is not
+           possible to wrap to a new line
+
+       If <EM>ch</EM> is a tab, newline, carriage return or backspace,  the  cursor  is
+       moved appropriately within the window:
+
+       <STRONG>o</STRONG>   Backspace  moves the cursor one character left; at the left edge of
+           a window it does nothing.
+
+       <STRONG>o</STRONG>   Carriage return moves the cursor to the window left margin  on  the
+           current line.
+
+       <STRONG>o</STRONG>   Newline  does  a <STRONG>clrtoeol</STRONG>, then moves the cursor to the window left
+           margin on the next line, scrolling the window if on the last line.
+
+       <STRONG>o</STRONG>   Tabs are considered to be at every eighth column.  The tab interval
+           may be altered by setting the <STRONG>TABSIZE</STRONG> variable.
+
+       If  <EM>ch</EM>  is  any  other nonprintable character, it is drawn in printable
+       form, i.e., the <STRONG>^</STRONG><EM>X</EM> notation used by <STRONG><A HREF="unctrl.3x.html">unctrl(3x)</A></STRONG>.   Calling  <STRONG>winch</STRONG>  after
+       adding  a  nonprintable character does not return the character itself,
+       but instead returns the printable representation of the character.
+
+       Video attributes can be combined with a character  argument  passed  to
+       <STRONG>addch</STRONG>  or  related  functions by logical-ORing them into the character.
+       (Thus, text, including attributes, can be  copied  from  one  place  to
+       another  using  <STRONG><A HREF="curs_inch.3x.html">inch(3x)</A></STRONG>  and  <STRONG>addch</STRONG>.)   See the <STRONG><A HREF="curs_attr.3x.html">curs_attr(3x)</A></STRONG> page for
+       values of predefined video attribute constants  that  can  be  usefully
+       OR'ed into characters.

+
+</PRE><H3><a name="h3-Echoing-characters">Echoing characters</a></H3><PRE>
+       The  <STRONG>echochar</STRONG>  and <STRONG>wechochar</STRONG> routines are equivalent to a call to <STRONG>addch</STRONG>
+       followed by a call to <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG>, or a call to <STRONG>waddch</STRONG>  followed  by  a
+       call  to <STRONG>wrefresh</STRONG>.  The knowledge that only a single character is being
+       output  is  used  and,  for  non-control  characters,  a   considerable
+       performance  gain  may be seen by using these routines instead of their
+       equivalents.

+           Solaris), while others define those to entries in an array.
+
+           This  implementation uses an array <STRONG>acs_map</STRONG>, as done in SVr4 curses.
+           NetBSD also uses an array, actually named <STRONG>_acs_char</STRONG>, with a <STRONG>#define</STRONG>
+           for compatibility.
+
+       <STRONG>o</STRONG>   HPUX curses equates some of the <STRONG>ACS_</STRONG> symbols to the analogous <STRONG>WACS_</STRONG>
+           symbols  as  if  the  <STRONG>ACS_</STRONG>  symbols  were  wide  characters.    The
+           misdefined  symbols  are the arrows and other symbols which are not
+           used for line-drawing.
+
+       <STRONG>o</STRONG>   X/Open Curses (issues 2 through 7) has a  typographical  error  for
+           the  ACS_LANTERN  symbol,  equating  its  "VT100+  Character"  to <STRONG>I</STRONG>
+           (capital I), while the header files for SVr4 curses and the various
+           implementations use <STRONG>i</STRONG> (lowercase).
+
+           None  of the terminal descriptions on Unix platforms use uppercase-
+           I,  except  for  Solaris  (i.e.,  <STRONG>screen</STRONG>'s  terminal   description,
+           apparently  based on the X/Open documentation around 1995).  On the
+           other hand, the terminal description <EM>gs6300</EM> (AT&amp;T PC6300 with EMOTS
+           Terminal Emulator) uses lowercase-i.
+
+       Some  ACS  symbols  (ACS_S3,  ACS_S7,  ACS_LEQUAL,  ACS_GEQUAL, ACS_PI,
+       ACS_NEQUAL, ACS_STERLING) were not documented in any publicly  released
+       System  V.   However,  many  publicly  available terminfos include <STRONG>acsc</STRONG>
+       strings in which their key characters (pryz{|})  are  embedded,  and  a
+       second-hand  list  of  their  character descriptions has come to light.
+       The ACS-prefixed names for them were invented for <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>.
+
+       The <EM>displayed</EM> values for the <STRONG>ACS_</STRONG> and <STRONG>WACS_</STRONG> constants depend on
+
+       <STRONG>o</STRONG>   the library configuration, i.e., <STRONG>ncurses</STRONG> versus <STRONG>ncursesw</STRONG>, where the
+           latter  is  capable  of displaying Unicode while the former is not,
+           and
+
+       <STRONG>o</STRONG>   whether the <EM>locale</EM> uses UTF-8 encoding.
+
+       In certain cases,  the  terminal  is  unable  to  display  line-drawing
+       characters   except   by   using   UTF-8   (see   the   discussion   of
+       <STRONG>NCURSES_NO_UTF8_ACS</STRONG> in <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>).
+
+
+</PRE><H3><a name="h3-Character-Set">Character Set</a></H3><PRE>
+       X/Open Curses assumes that the parameter passed to  <STRONG>waddch</STRONG>  contains  a
+       single  character.   As  discussed in <STRONG><A HREF="curs_attr.3x.html">curs_attr(3x)</A></STRONG>, that character may
+       have been more than eight bits in an SVr3 or SVr4  implementation,  but
+       in  the  X/Open Curses model, the details are not given.  The important
+       distinction between SVr4 curses and X/Open  Curses  is  that  the  non-
+       character  information  (attributes  and  color) was separated from the
+       character information which is packed in a <STRONG>chtype</STRONG> to pass to <STRONG>waddch</STRONG>.
+
+       In this implementation,  <STRONG>chtype</STRONG>  holds  an  eight-bit  character.   But
+       ncurses  allows  multibyte  characters  to be passed in a succession of
+       calls to <STRONG>waddch</STRONG>.  The other implementations do not do this; a  call  to
+       <STRONG>waddch</STRONG>  passes  exactly  one  character which may be rendered as one or
+       more cells on the screen depending on whether it is printable.
+
+       Depending on the locale settings, ncurses will inspect the byte  passed
+       in  each  call  to <STRONG>waddch</STRONG>, and check if the latest call will continue a
+       multibyte sequence.  When a character is <EM>complete</EM>, ncurses displays the
+       character and moves to the next position in the screen.
+
+       If  the  calling  application  interrupts  the succession of bytes in a
+       multibyte character by moving the current location (e.g., using <STRONG>wmove</STRONG>),
+       ncurses discards the partially built character, starting over again.
+
+       For  portability  to  other  implementations,  do  not  rely  upon this
+       behavior:
+
+       <STRONG>o</STRONG>   check if a character can be represented as a  single  byte  in  the
+           current locale before attempting call <STRONG>waddch</STRONG>, and
+
+       <STRONG>o</STRONG>   call <STRONG>wadd_wch</STRONG> for characters which cannot be handled by <STRONG>waddch</STRONG>.
+
+
+</PRE><H3><a name="h3-TABSIZE">TABSIZE</a></H3><PRE>
+       The  <STRONG>TABSIZE</STRONG>  variable  is  implemented  in  SVr4 and other versions of
+       curses, but is not part of X/Open curses  (see  <STRONG><A HREF="curs_variables.3x.html">curs_variables(3x)</A></STRONG>  for
+       more details).
+
+       If <EM>ch</EM> is a carriage return, the cursor is moved to the beginning of the
+       current row of the window.  This is true of other implementations,  but
+       is not documented.

+       These functions write the (null-terminated) character string <EM>str</EM> on the
+       given window.  It is similar to calling <STRONG>waddch</STRONG> once for  each  byte  in
+       the string.
+
+       The <EM>mv</EM> functions perform cursor movement once, before writing any char-
+       acters.  Thereafter, the cursor is advanced as a side-effect of writing
+       to the window.
+
+       The  four  functions with <EM>n</EM> as the last argument write at most <EM>n</EM> bytes,
+       or until a terminating null is reached.  If <EM>n</EM> is -1,  then  the  entire
+       string will be added.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.
+
+       X/Open  does  not define any error conditions.  This implementation re-
+       turns an error
+
+       <STRONG>o</STRONG>   if the window pointer is null or
+
+       <STRONG>o</STRONG>   if the string pointer is null or
+
+       <STRONG>o</STRONG>   if the corresponding calls to <STRONG>waddch</STRONG> return an error.
+
+       Functions with a "mv" prefix first  perform  a  cursor  movement  using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.  If an error is returned by the  <STRONG>wmove</STRONG>,  no
+       characters are added to the window.
+
+       If  an  error  is  returned  by <STRONG>waddch</STRONG> (e.g., because the window is not
+       large enough, or an illegal byte sequence was detected)  only  part  of
+       the  string  may be added.  Aside from that, there is a special case in
+       <STRONG>waddch</STRONG> where an error may be  returned  after  successfully  writing  a
+       character  to  the lower-right corner of a window when <STRONG>scrollok</STRONG> is dis-
+       abled.

+       These  routines  manipulate the current attributes of the named window,

+       with  <STRONG>waddch</STRONG>,  <STRONG>waddstr</STRONG>  and  <STRONG>wprintw</STRONG>.  Attributes are a property of the
+       character, and move with the character through any  scrolling  and  in-
+       sert/delete  line/character  operations.   To the extent possible, they
+       are displayed as appropriate modifications to the graphic rendition  of
+       characters put on the screen.
+
+       These  routines do not affect the attributes used when erasing portions
+       of the window.  See <STRONG><A HREF="curs_bkgd.3x.html">curs_bkgd(3x)</A></STRONG> for functions which  modify  the  at-

+       There are two sets of functions:

+           <STRONG>tr_set</STRONG> and <STRONG>wattr_get</STRONG>.
+
+       <STRONG>o</STRONG>   functions  for manipulating only the window attributes (not color):
+           <STRONG>wattr_on</STRONG> and <STRONG>wattr_off</STRONG>.
+
+       The <STRONG>wattr_set</STRONG> function sets the current attributes of the given  window
+       to <EM>attrs</EM>, with color specified by <EM>pair</EM>.
+
+       Use <STRONG>wattr_get</STRONG> to retrieve attributes for the given window.
+
+       Use  <STRONG>attr_on</STRONG>  and  <STRONG>wattr_on</STRONG>  to turn on window attributes, i.e., values
+       OR'd together in <EM>attr</EM>, without affecting  other  attributes.   Use  <STRONG>at-</STRONG>
+       <STRONG>tr_off</STRONG>  and  <STRONG>wattr_off</STRONG> to turn off window attributes, again values OR'd
+       together in <EM>attr</EM>, without affecting other attributes.
+
+
+</PRE><H3><a name="h3-Legacy-window-attributes">Legacy window attributes</a></H3><PRE>
+       The X/Open window attribute routines which <EM>set</EM> or <EM>get</EM>, turn <EM>on</EM>  or  <EM>off</EM>
+       are extensions of older routines which assume that color pairs are OR'd
+       into the attribute parameter.  These newer routines use similar  names,
+       because X/Open simply added an underscore (<STRONG>_</STRONG>) for the newer names.
+
+       The <STRONG>int</STRONG> datatype used in the legacy routines is treated as if it is the
+       same size as <STRONG>chtype</STRONG> (used by <STRONG><A HREF="curs_addch.3x.html">addch(3x)</A></STRONG>).  It holds the common video at-
+       tributes  (such  as  bold,  reverse),  as well as a few bits for color.
+       Those bits correspond to the <STRONG>A_COLOR</STRONG> symbol.  The <STRONG>COLOR_PAIR</STRONG> macro pro-
+       vides  a value which can be OR'd into the attribute parameter.  For ex-
+       ample, as long as that value fits into the  <STRONG>A_COLOR</STRONG>  mask,  then  these
+       calls produce similar results:
+
+           attrset(A_BOLD | COLOR_PAIR(<EM>pair</EM>));
+           attr_set(A_BOLD, <EM>pair</EM>, NULL);
+
+       However, if the value does not fit, then the <STRONG>COLOR_PAIR</STRONG> macro uses only
+       the bits that fit.  For example, because in ncurses <STRONG>A_COLOR</STRONG>  has  eight
+       (8) bits, then <STRONG>COLOR_PAIR(</STRONG><EM>259</EM><STRONG>)</STRONG> is 4 (i.e., 259 is 4 more than the limit
+       255).
+
+       The <STRONG>PAIR_NUMBER</STRONG> macro extracts a pair number from an <STRONG>int</STRONG>  (or  <STRONG>chtype</STRONG>).
+       For  example,  the <EM>input</EM> and <EM>output</EM> values in these statements would be
+       the same:
+
+           int value = A_BOLD | COLOR_PAIR(<EM>input</EM>);
+           int <EM>output</EM> = PAIR_NUMBER(value);
+
+       The <STRONG>attrset</STRONG> routine is a legacy feature predating SVr4 curses but  kept
+       in X/Open Curses for the same reason that SVr4 curses kept it: compati-
+       bility.
+
+       The remaining <STRONG>attr</STRONG>* functions operate exactly  like  the  corresponding
+       <STRONG>attr_</STRONG>*  functions,  except  that they take arguments of type <STRONG>int</STRONG> rather
+       than <STRONG>attr_t</STRONG>.
+
+       There is no corresponding <STRONG>attrget</STRONG> function as such  in  X/Open  Curses,
+       although ncurses provides <STRONG>getattrs</STRONG> (see <STRONG><A HREF="curs_legacy.3x.html">curs_legacy(3x)</A></STRONG>).

+       X/Open Curses is largely based  on  SVr4  curses,  adding  support  for
+       "wide-characters"  (not  specific to Unicode).  Some of the X/Open dif-
+       ferences from SVr4 curses address the way video attributes can  be  ap-
+       plied  to  wide-characters.   But aside from that, <STRONG>attrset</STRONG> and <STRONG>attr_set</STRONG>
+       are similar.  SVr4 curses provided the basic features for  manipulating
+       video  attributes.  However, earlier versions of curses provided a part
+       of these features.
+
+       As seen in 2.8BSD, curses assumed 7-bit characters,  using  the  eighth
+       bit  of  a byte to represent the <EM>standout</EM> feature (often implemented as
+       bold and/or reverse video).  The BSD curses library provided  functions
+       <STRONG>standout</STRONG>  and  <STRONG>standend</STRONG> which were carried along into X/Open Curses due
+       to their pervasive use in legacy applications.
+
+       Some terminals in the 1980s  could  support  a  variety  of  video  at-
+       tributes,  although the BSD curses library could do nothing with those.
+       System V (1983) provided an improved curses library.  It defined the <STRONG>A_</STRONG>
+       symbols  for  use  by  applications to manipulate the other attributes.
+       There are few useful references for the chronology.
+
+       Goodheart's book <EM>UNIX</EM> <EM>Curses</EM> <EM>Explained</EM> (1991)  describes  SVr3  (1987),
+       commenting on several functions:
+
+       <STRONG>o</STRONG>   the  <STRONG>attron</STRONG>,  <STRONG>attroff</STRONG>, <STRONG>attrset</STRONG> functions (and most of the functions
+           found in SVr4 but not in BSD curses) were introduced by System V,
+
+       <STRONG>o</STRONG>   the alternate character set feature with <STRONG>A_ALTCHARSET</STRONG> was added  in
+           SVr2 and improved in SVr3 (by adding <STRONG>acs_map[]</STRONG>),
+
+       <STRONG>o</STRONG>   <STRONG>start_color</STRONG>  and  related color-functions were introduced by System
+           V.3.2,
+
+       <STRONG>o</STRONG>   pads, soft-keys were added in SVr3, and
+
+       Goodheart did not mention the background character or the <STRONG>cchar_t</STRONG> type.
+       Those are respectively SVr4 and X/Open features.  He did mention the <STRONG>A_</STRONG>
+       constants, but did not indicate their values.  Those were not the  same
+       in different systems, even for those marked as System V.
+
+       Different  Unix  systems  used  different  sizes  for the bit-fields in
+       <STRONG>chtype</STRONG> for <EM>characters</EM> and <EM>colors</EM>, and took into account  the  different
+       integer sizes (32-bit versus 64-bit).
+
+       This  table  showing  the number of bits for <STRONG>A_COLOR</STRONG> and <STRONG>A_CHARTEXT</STRONG> was
+       gleaned from the curses header files for various operating systems  and
+       architectures.   The inferred architecture and notes reflect the format
+       and size of the defined constants as well as clues such as  the  alter-
+       nate  character  set implementation.  A 32-bit library can be used on a
+       64-bit system, but not necessarily the reverse.

+              in 1996.
+
+          <STRONG>o</STRONG>   HP-UX  10.30 (1997) marked "curses_colr" obsolete.  That version
+              of curses was dropped with HP-UX 11.30 in 2006.
+
+          Regarding OSF/1 (and Tru64),
+
+          <STRONG>o</STRONG>   These used 64-bit hardware.  Like ncurses, the OSF/1 curses  in-
+              terface is not customized for 32-bit and 64-bit versions.
+
+          <STRONG>o</STRONG>   Unlike other systems which evolved from AT&amp;T code, OSF/1 provid-
+              ed a new implementation for X/Open curses.
+
+          Regarding Solaris,
+
+          <STRONG>o</STRONG>   The initial release of Solaris was in 1992.
+
+          <STRONG>o</STRONG>   The <EM>xpg4</EM> (X/Open) curses was developed by MKS from 1990 to 1995.
+              Sun's copyright began in 1996.
+
+          <STRONG>o</STRONG>   Sun updated the X/Open curses interface after 64-bit support was
+              introduced in 1997, but did not modify the  SVr4  curses  inter-
+              face.
+
+          Regarding U/Win,
+
+          <STRONG>o</STRONG>   Development  of  the  curses  library  began in 1991, stopped in
+              2000.
+
+          <STRONG>o</STRONG>   Color support was added in 1998.
+
+          <STRONG>o</STRONG>   The library uses only <STRONG>chtype</STRONG> (no <STRONG>cchar_t</STRONG>).

+       Once X/Open curses was adopted in the mid-1990s, the  constraint  of  a
+       32-bit interface with many colors and wide-characters for <STRONG>chtype</STRONG> became
+       a moot point.  The <STRONG>cchar_t</STRONG> structure (whose size and  members  are  not
+       specified in X/Open Curses) could be extended as needed.
+
+       Other interfaces are rarely used now:
+
+       <STRONG>o</STRONG>   BSD  curses was improved slightly in 1993/1994 using Keith Bostic's
+           modification to make the library 8-bit clean for <STRONG>nvi(1)</STRONG>.  He  moved
+           <EM>standout</EM> attribute to a structure member.
+
+           The  resulting  4.4BSD curses was replaced by ncurses over the next
+           ten years.
+
+       <STRONG>o</STRONG>   U/Win is rarely used now.

+       This implementation provides the <STRONG>A_ITALIC</STRONG> attribute for terminals which
+       have  the  <STRONG>enter_italics_mode</STRONG> (<STRONG>sitm</STRONG>) and <STRONG>exit_italics_mode</STRONG> (<STRONG>ritm</STRONG>) capa-
+       bilities.  Italics are not mentioned in X/Open Curses.  Unlike the oth-
+       er  video attributes, <STRONG>A_ITALIC</STRONG> is unrelated to the <STRONG>set_attributes</STRONG> capa-
+       bilities.  This implementation makes the  assumption  that  <STRONG>exit_attri-</STRONG>
+       <STRONG>bute_mode</STRONG> may also reset italics.
+
+       Each  of  the functions added by XSI Curses has a parameter <EM>opts</EM>, which
+       X/Open Curses still (after more than twenty  years)  documents  as  re-
+       served for future use, saying that it should be <STRONG>NULL</STRONG>.  This implementa-
+       tion uses that parameter in ABI 6 for the functions which have a color-
+       pair parameter to support <EM>extended</EM> <EM>color</EM> <EM>pairs</EM>:
+
+       <STRONG>o</STRONG>   For functions which modify the color, e.g., <STRONG>wattr_set</STRONG> and <STRONG>wattr_on</STRONG>,
+           if <EM>opts</EM> is set it is treated as a pointer to <STRONG>int</STRONG>, and used  to  set
+           the color pair instead of the <STRONG>short</STRONG> <EM>pair</EM> parameter.
+
+       <STRONG>o</STRONG>   For functions which retrieve the color, e.g., <STRONG>wattr_get</STRONG>, if <EM>opts</EM> is
+           set it is treated as a pointer to <STRONG>int</STRONG>, and  used  to  retrieve  the
+           color  pair  as  an <STRONG>int</STRONG> value, in addition to retrieving it via the
+           standard pointer to <STRONG>short</STRONG> parameter.
+
+       <STRONG>o</STRONG>   For functions which turn attributes off, e.g., <STRONG>wattr_off</STRONG>, the  <EM>opts</EM>
+           parameter is ignored except except to check that it is <STRONG>NULL</STRONG>.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       These functions are supported in the XSI Curses standard, Issue 4.  The
+       standard defined the dedicated type for highlights, <STRONG>attr_t</STRONG>,  which  was
+       not defined in SVr4 curses.  The functions taking <STRONG>attr_t</STRONG> arguments were
+       not supported under SVr4.
+
+       Very old versions of this library did not force an update of the screen
+       when  changing  the  attributes.   Use  <STRONG>touchwin</STRONG> to force the screen to
+       match the updated attributes.
+
+       The XSI Curses standard states that whether the  traditional  functions
+       <STRONG>attron</STRONG>/<STRONG>attroff</STRONG>/<STRONG>attrset</STRONG>  can  manipulate  attributes other than <STRONG>A_BLINK</STRONG>,
+       <STRONG>A_BOLD</STRONG>, <STRONG>A_DIM</STRONG>, <STRONG>A_REVERSE</STRONG>, <STRONG>A_STANDOUT</STRONG>, or <STRONG>A_UNDERLINE</STRONG> is  "unspecified".
+       Under  this implementation as well as SVr4 curses, these functions cor-
+       rectly manipulate all  other  highlights  (specifically,  <STRONG>A_ALTCHARSET</STRONG>,
+       <STRONG>A_PROTECT</STRONG>, and <STRONG>A_INVIS</STRONG>).
+
+       XSI Curses added these entry points:
+
+              <STRONG>attr_get</STRONG>, <STRONG>attr_on</STRONG>, <STRONG>attr_off</STRONG>, <STRONG>attr_set</STRONG>, <STRONG>wattr_on</STRONG>, <STRONG>wattr_off</STRONG>, <STRONG>wat-</STRONG>
+              <STRONG>tr_get</STRONG>, <STRONG>wattr_set</STRONG>
+
+       The new functions are intended to work with a new series  of  highlight
+       macros prefixed with <STRONG>WA_</STRONG>.  The older macros have direct counterparts in
+       the newer set of names:
+
+              <STRONG>Name</STRONG>            <STRONG>Description</STRONG>
+              ------------------------------------------------------------
+              <STRONG>WA_NORMAL</STRONG>       Normal display (no highlight)
+              <STRONG>WA_STANDOUT</STRONG>     Best highlighting mode of the terminal.
+              <STRONG>WA_UNDERLINE</STRONG>    Underlining
+              <STRONG>WA_REVERSE</STRONG>      Reverse video
+              <STRONG>WA_BLINK</STRONG>        Blinking
+              <STRONG>WA_DIM</STRONG>          Half bright
+              <STRONG>WA_BOLD</STRONG>         Extra bright or bold
+              <STRONG>WA_ALTCHARSET</STRONG>   Alternate character set
+
+       XSI curses does not assign values to these symbols, nor does  it  state
+       whether or not they are related to the similarly-named A_NORMAL, etc.:
+
+       <STRONG>o</STRONG>   The  XSI  curses standard specifies that each pair of corresponding
+           <STRONG>A_</STRONG> and <STRONG>WA_</STRONG>-using functions operates on the  same  current-highlight
+           information.
+
+       <STRONG>o</STRONG>   However, in some implementations, those symbols have unrelated val-
+           ues.
+
+           For example, the Solaris <EM>xpg4</EM> (X/Open) curses declares <STRONG>attr_t</STRONG> to be
+           an unsigned short integer (16-bits), while <STRONG>chtype</STRONG> is a unsigned in-
+           teger (32-bits).  The <STRONG>WA_</STRONG> symbols in this case are  different  from
+           the  <STRONG>A_</STRONG>  symbols because they are used for a smaller datatype which
+           does not represent <STRONG>A_CHARTEXT</STRONG> or <STRONG>A_COLOR</STRONG>.
+
+           In this implementation (as in many others), the values happen to be
+           the  same  because it simplifies copying information between <STRONG>chtype</STRONG>
+           and <STRONG>cchar_t</STRONG> variables.
+
+       <STRONG>o</STRONG>   Because ncurses's <STRONG>attr_t</STRONG> can hold a  color  pair  (in  the  <STRONG>A_COLOR</STRONG>
+           field),  a  call to <STRONG>wattr_on</STRONG>, <STRONG>wattr_off</STRONG>, or <STRONG>wattr_set</STRONG> may alter the
+           window's color.  If the color pair information in the attribute pa-
+           rameter is zero, no change is made to the window's color.
+
+           This is consistent with SVr4 curses; X/Open Curses does not specify
+           this.
+
+       The XSI standard extended conformance level adds new highlights <STRONG>A_HORI-</STRONG>
+       <STRONG>ZONTAL</STRONG>,  <STRONG>A_LEFT</STRONG>,  <STRONG>A_LOW</STRONG>,  <STRONG>A_RIGHT</STRONG>, <STRONG>A_TOP</STRONG>, <STRONG>A_VERTICAL</STRONG> (and corresponding
+       <STRONG>WA_</STRONG> macros for each).  As of August 2013, no  known  terminal  provides
+       these highlights (i.e., via the <STRONG>sgr1</STRONG> capability).
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       All routines return the integer <STRONG>OK</STRONG> on success, or <STRONG>ERR</STRONG> on failure.
+
+       X/Open does not define any error conditions.
+
+       This implementation
+
+       <STRONG>o</STRONG>   returns an error if the window pointer is null.
+
+       <STRONG>o</STRONG>   returns an error if the color pair parameter for <STRONG>wcolor_set</STRONG> is out-
+           side the range 0..COLOR_PAIRS-1.
+
+       <STRONG>o</STRONG>   does not return an error if either of the parameters  of  <STRONG>wattr_get</STRONG>
+           used for retrieving attribute or color-pair values is <STRONG>NULL</STRONG>.
+
+       Functions  with  a  "mv"  prefix  first perform a cursor movement using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.

+       The <STRONG>bkgdset</STRONG> and <STRONG>wbkgdset</STRONG> routines set the <EM>background</EM> for a  window.   A
+       window's  background  is  a  <STRONG>chtype</STRONG>  consisting  of  any combination of
+       attributes (i.e., rendition) and a character:
+
+       <STRONG>o</STRONG>   The attribute part of the background is combined (OR'ed)  with  all
+           non-blank characters that are written into the window with <STRONG>waddch</STRONG>.
+
+       <STRONG>o</STRONG>   Both  the  character  and  attribute  parts  of  the background are
+           combined with blank characters that are written into the window.
+
+       The background becomes a property of each character and moves with  the
+       character   through  any  scrolling  and  insert/delete  line/character
+       operations.
+
+       To the extent possible on a particular terminal, the attribute part  of
+       the  background  is displayed as the graphic rendition of the character
+       put on the screen.
+
+
+</PRE><H3><a name="h3-bkgd">bkgd</a></H3><PRE>
+       The <STRONG>bkgd</STRONG> and <STRONG>wbkgd</STRONG> functions set the background property of the current
+       or  specified  window  and  then  apply this setting to every character
+       position in that window.  According to  X/Open  Curses,  it  should  do
+       this:
+
+       <STRONG>o</STRONG>   The  rendition  of  every character on the screen is changed to the
+           new background rendition.
+
+       <STRONG>o</STRONG>   Wherever the former background character appears, it is changed  to
+           the new background character.
+
+       Neither  X/Open Curses nor the SVr4 manual pages give details about the
+       way the rendition of characters on the screen is updated when  <STRONG>bkgd</STRONG>  or
+       <STRONG>wbkgd</STRONG> is used to change the background character.
+
+       This  implementation,  like  SVr4 curses, does not store the background
+       and window attribute contributions to each cell separately.  It updates
+       the  rendition  by  comparing  the  character, non-color attributes and
+       colors contained in the background.   For  each  cell  in  the  window,
+       whether or not it is blank:
+
+       <STRONG>o</STRONG>   The  library  first  compares  the <EM>character</EM>, and if it matches the
+           current character part of the background, it replaces that with the
+           new background character.
+
+           When <STRONG>bkgdset</STRONG> is used to set the background character, that does not
+           update each cell in the window.  A subsequent  call  to  <STRONG>bkgd</STRONG>  will
+           only  modify  the  <EM>character</EM>  in  cells  which  match  the  current
+           background character.
+
+       <STRONG>o</STRONG>   The library then checks if the cell uses  color,  i.e.,  its  color
+           pair  value  is nonzero.  If not, it simply replaces the attributes
+           and color pair in the cell  with  those  from  the  new  background
+           character.
+
+       <STRONG>o</STRONG>   If  the  cell uses color, and that matches the color in the current
+           background, the library removes attributes which may have come from
+           the current background and adds attributes from the new background.
+           It finishes by setting the cell to  use  the  color  from  the  new
+           background.
+
+       <STRONG>o</STRONG>   If  the  cell  uses color, and that does not match the color in the
+           current  background,  the  library  updates  only   the   non-color
+           attributes,  first  removing  those  which  may  have come from the
+           current  background,  and  then  adding  attributes  from  the  new
+           background.
+
+       If the background's character value is zero (0), a space is assumed.
+
+       If  the  terminal  does  not  support  color,  or if color has not been
+       started  with  <STRONG>start_color</STRONG>,  the  new  background   character's   color
+       attribute will be ignored.

+       The  <STRONG>getbkgd</STRONG>  function  returns  the  given window's current background

+       These functions are described in the XSI Curses standard, Issue 4.   It
+       specifies  that  <STRONG>bkgd</STRONG>  and  <STRONG>wbkgd</STRONG>  return  <STRONG>ERR</STRONG> on failure, but gives no
+       failure conditions.
+
+       The routines <STRONG>bkgd</STRONG> and <STRONG>wbkgd</STRONG> return the integer <STRONG>OK</STRONG>, unless  the  library
+       has not been initialized.
+
+       In  contrast, the SVr4.0 manual says <STRONG>bkgd</STRONG> and <STRONG>wbkgd</STRONG> may return <STRONG>OK</STRONG> "or a
+       non-negative integer if <STRONG>immedok</STRONG> is set", which  refers  to  the  return
+       value  from <STRONG>wrefresh</STRONG> (used to implement the immediate repainting).  The
+       SVr4 curses <STRONG>wrefresh</STRONG> returns the number of characters  written  to  the
+       screen during the refresh.  This implementation does not do that.

+       Note that <STRONG>bkgdset</STRONG> and <STRONG>bkgd</STRONG> may be macros.
+
+       X/Open  Curses  mentions that the character part of the background must
+       be a single-byte value.  This  implementation,  like  SVr4,  checks  to
+       ensure  that,  and will reuse the old background character if the check
+       fails.

+       All  routines return the integer <STRONG>OK</STRONG>.  The SVr4.0 manual says "or a non-

+
+       X/Open does not define any error conditions.  This  implementation  re-
+       turns an error if the window pointer is null.
+
+       Functions  with  a  "mv"  prefix  first perform a cursor movement using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.

+       screen.   That is, they erase all lines below the cursor in the window.
+       Also, the current line to  the  right  of  the  cursor,  inclusive,  is
+       erased.

+       All routines return the integer <STRONG>OK</STRONG> on success and <STRONG>ERR</STRONG> on failure.
+
+       X/Open defines no error conditions.  In this implementation,
+
+       <STRONG>o</STRONG>   functions using a window pointer parameter return an error if it is
+           null
+
+       <STRONG>o</STRONG>   <STRONG>wclrtoeol</STRONG> returns an error if the cursor position is about to wrap.

+       Note  that  <STRONG>erase</STRONG>, <STRONG>werase</STRONG>, <STRONG>clear</STRONG>, <STRONG>wclear</STRONG>, <STRONG>clrtobot</STRONG>, and <STRONG>clrtoeol</STRONG> may be
+       macros.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       These functions are described in the XSI Curses standard, Issue 4.  The
+       standard  specifies  that  they return <STRONG>ERR</STRONG> on failure, but specifies no
+       error conditions.
+
+       The SVr4.0 manual says that these functions could return  "a  non-nega-
+       tive  integer  if <STRONG><A HREF="curs_outopts.3x.html">immedok(3x)</A></STRONG> is set", referring to the return-value of
+       <STRONG>wrefresh</STRONG>.  In that implementation, <STRONG>wrefresh</STRONG> would return a count of the
+       number of characters written to the terminal.
+
+       Some  historic  curses implementations had, as an undocumented feature,
+       the ability to do the equivalent of <STRONG>clearok(...,</STRONG> <STRONG>1)</STRONG>  by  saying  <STRONG>touch-</STRONG>
+       <STRONG>win(stdscr)</STRONG> or <STRONG>clear(stdscr)</STRONG>.  This will not work under ncurses.
+
+       This implementation, and others such as Solaris, sets the current posi-
+       tion to 0,0 after erasing via <STRONG>werase</STRONG> and <STRONG>wclear</STRONG>.  That fact is not doc-
+       umented  in  other  implementations, and may not be true of implementa-
+       tions which were not derived from SVr4 source.
+
+       Not obvious from the description, most implementations clear the screen
+       after  <STRONG>wclear</STRONG>  even  for  a subwindow or derived window.  If you do not
+       want to clear the screen during the next <STRONG>wrefresh</STRONG>, use <STRONG>werase</STRONG> instead.

+       <STRONG>curses</STRONG> supports color attributes on terminals with that capability.  To
+       use  these  routines  <STRONG>start_color</STRONG>  must  be called, usually right after
+       <STRONG>initscr</STRONG>.  Colors are always used in pairs (referred to as color-pairs).
+       A  color-pair  consists  of  a  foreground color (for characters) and a
+       background color (for the blank field on which the characters are  dis-
+       played).   A  programmer  initializes  a  color-pair  with  the routine
+       <STRONG>init_pair</STRONG>.  After it has been initialized, <STRONG>COLOR_PAIR</STRONG>(<EM>n</EM>) can be used to
+       convert the pair to a video attribute.
+
+       If  a  terminal is capable of redefining colors, the programmer can use
+       the routine <STRONG>init_color</STRONG> to change the definition of a color.   The  rou-
+       tines  <STRONG>has_colors</STRONG>  and <STRONG>can_change_color</STRONG> return <STRONG>TRUE</STRONG> or <STRONG>FALSE</STRONG>, depending
+       on whether the terminal has color capabilities and whether the program-
+       mer can change the colors.  The routine <STRONG>color_content</STRONG> allows a program-
+       mer to extract the amounts of red, green, and  blue  components  in  an
+       initialized  color.   The  routine  <STRONG>pair_content</STRONG> allows a programmer to
+       find out how a given color-pair is currently defined.
+
+
+</PRE><H3><a name="h3-Color-Rendering">Color Rendering</a></H3><PRE>
+       The <STRONG>curses</STRONG> library combines these inputs to produce  the  actual  fore-
+       ground and background colors shown on the screen:
+
+       <STRONG>o</STRONG>   per-character video attributes (e.g., via <STRONG>waddch</STRONG>),
+
+       <STRONG>o</STRONG>   the window attribute (e.g., by <STRONG>wattrset</STRONG>), and
+
+       <STRONG>o</STRONG>   the background character (e.g., <STRONG>wbkgdset</STRONG>).
+
+       Per-character and window attributes are usually set by a parameter con-
+       taining video attributes including a color pair value.  Some  functions
+       such as <STRONG>wattr_set</STRONG> use a separate parameter which is the color pair num-
+       ber.
+
+       The background character is a special case:  it  includes  a  character
+       value, just as if it were passed to <STRONG>waddch</STRONG>.
+
+       The  <STRONG>curses</STRONG> library does the actual work of combining these color pairs
+       in an internal function called from <STRONG>waddch</STRONG>:
+
+       <STRONG>o</STRONG>   If the parameter passed to <STRONG>waddch</STRONG> is <EM>blank</EM>, and it uses the special
+           color pair 0,
+
+           <STRONG>o</STRONG>   <STRONG>curses</STRONG> next checks the window attribute.
+
+           <STRONG>o</STRONG>   If  the window attribute does not use color pair 0, <STRONG>curses</STRONG> uses
+               the color pair from the window attribute.
+
+           <STRONG>o</STRONG>   Otherwise, <STRONG>curses</STRONG> uses the background character.
+
+       <STRONG>o</STRONG>   If the parameter passed to <STRONG>waddch</STRONG> is <EM>not</EM> <EM>blank</EM>, or it does not  use
+           the  special  color  pair 0, <STRONG>curses</STRONG> prefers the color pair from the
+           parameter, if it is nonzero.  Otherwise, it tries the window attri-
+           bute next, and finally the background character.
+
+       Some  <STRONG>curses</STRONG>  functions such as <STRONG>wprintw</STRONG> call <STRONG>waddch</STRONG>.  Those do not com-
+       bine its parameter with a color pair.  Consequently those calls use on-
+       ly the window attribute or the background character.

+       The <STRONG>start_color</STRONG> routine requires no arguments.  It must  be  called  if
+       the  programmer wants to use colors, and before any other color manipu-
+       lation routine is called.  It is good practice  to  call  this  routine
+       right after <STRONG>initscr</STRONG>.  <STRONG>start_color</STRONG> does this:
+
+       <STRONG>o</STRONG>   It  initializes  two  global variables, <STRONG>COLORS</STRONG> and <STRONG>COLOR_PAIRS</STRONG> (re-
+           spectively defining the maximum number of  colors  and  color-pairs
+           the terminal can support).
+
+       <STRONG>o</STRONG>   It  initializes  the special color pair <STRONG>0</STRONG> to the default foreground
+           and background colors.  No other color pairs are initialized.
+
+       <STRONG>o</STRONG>   It restores the colors on the terminal to the values they had  when
+           the terminal was just turned on.
+
+       <STRONG>o</STRONG>   If  the  terminal supports the <STRONG>initc</STRONG> (<STRONG>initialize_color</STRONG>) capability,
+           <STRONG>start_color</STRONG> initializes its internal table  representing  the  red,
+           green, and blue components of the color palette.
+
+           The components depend on whether the terminal uses CGA (aka "ANSI")
+           or HLS (i.e.,  the  <STRONG>hls</STRONG>  (<STRONG>hue_lightness_saturation</STRONG>)  capability  is
+           set).   The  table  is  initialized  first  for  eight basic colors
+           (black, red, green, yellow, blue, magenta, cyan, and white),  using
+           weights that depend upon the CGA/HLS choice.  For "ANSI" colors the
+           weights are <STRONG>680</STRONG> or <STRONG>0</STRONG> depending on whether  the  corresponding  red,
+           green,  or  blue component is used or not.  That permits using <STRONG>1000</STRONG>
+           to represent bold/bright colors.  After the  initial  eight  colors
+           (if  the  terminal  supports more than eight colors) the components
+           are initialized using the same pattern, but with weights  of  <STRONG>1000</STRONG>.
+           SVr4 uses a similar scheme, but uses <STRONG>1000</STRONG> for the components of the
+           initial eight colors.
+
+           <STRONG>start_color</STRONG> does not attempt to set the terminal's color palette to
+           match its built-in table.  An application may use <STRONG>init_color</STRONG> to al-
+           ter the internal table along with the terminal's color.
+
+       These limits apply to color values and  color  pairs.   Values  outside
+       these limits are not legal, and may result in a runtime error:

+       SVr3.2 introduced color support to curses in 1987.
+
+       SVr4 made internal changes, e.g., moving  the  storage  for  the  color
+       state  from  <STRONG>SP</STRONG> (the <STRONG>SCREEN</STRONG> structure) to <STRONG>cur_term</STRONG> (the <STRONG>TERMINAL</STRONG> struc-
+       ture), but provided the same set of library functions.
+
+       SVr4 curses limits the number of color pairs  to  64,  reserving  color
+       pair  zero  (0)  as the terminal's initial uncolored state.  This limit
+       arises because the color pair information is a bitfield in  the  <STRONG>chtype</STRONG>
+       data type (denoted by <STRONG>A_COLOR</STRONG>).
+
+       Other implementations of curses had different limits:
+
+       <STRONG>o</STRONG>   PCCurses (1987-1990) provided for only eight (8) colors.
+
+       <STRONG>o</STRONG>   PDCurses  (1992-present)  inherited the 8-color limitation from PC-
+           Curses, but changed this to 256 in version 2.5 (2001),  along  with
+           changing <STRONG>chtype</STRONG> from 16-bits to 32-bits.
+
+       <STRONG>o</STRONG>   X/Open Curses (1992-present) added a new structure <STRONG>cchar_t</STRONG> to store
+           the character, attributes and color-pair values, allowing increased
+           range  of  color-pairs.   Both  color-pairs and color-values used a
+           signed <STRONG>short</STRONG>, limiting values to 15 bits.
+
+       <STRONG>o</STRONG>   ncurses (1992-present) uses eight bits for <STRONG>A_COLOR</STRONG> in  <STRONG>chtype</STRONG>  val-
+           ues.
+
+           Version  5.3  provided  a wide-character interface (2002), but left
+           color-pairs as part of the attributes-field.
+
+           Since version 6 (2015), ncurses uses a separate <STRONG>int</STRONG> for color-pairs
+           in the <STRONG>cchar_t</STRONG> values.  When those color-pair values fit in 8 bits,
+           ncurses allows color-pairs to be manipulated via the functions  us-

+       <STRONG>o</STRONG>   NetBSD  curses  used  6 bits from 2000 (when colors were first sup-
+           ported) until 2004.  At that point, NetBSD changed to use 10  bits.
+           As of 2021, that size is unchanged.  Like ncurses before version 6,
+           the NetBSD color-pair information is stored in the attributes field
+           of  <STRONG>cchar_t</STRONG>,  limiting the number of color-pairs by the size of the
+           bitfield.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       This implementation satisfies XSI Curses's minimum maximums for  <STRONG>COLORS</STRONG>
+       and <STRONG>COLOR_PAIRS</STRONG>.
+
+       The  <STRONG>init_pair</STRONG>  routine accepts negative values of foreground and back-
+       ground color to support the <STRONG><A HREF="default_colors.3x.html">use_default_colors(3x)</A></STRONG> extension, but  only
+       if that routine has been first invoked.
+
+       The assumption that <STRONG>COLOR_BLACK</STRONG> is the default background color for all
+       terminals can be modified using  the  <STRONG><A HREF="default_colors.3x.html">assume_default_colors(3x)</A></STRONG>  exten-
+       sion.
+
+       This  implementation checks the pointers, e.g., for the values returned
+       by <STRONG>color_content</STRONG> and <STRONG>pair_content</STRONG>, and will treat those as optional pa-
+       rameters when null.
+
+       X/Open  Curses  does  not  specify a limit for the number of colors and
+       color pairs which a terminal can support.  However, in its use of <STRONG>short</STRONG>
+       for  the  parameters,  it carries over SVr4's implementation detail for
+       the compiled terminfo database, which uses signed 16-bit numbers.  This
+       implementation  provides extended versions of those functions which use
+       <STRONG>short</STRONG> parameters, allowing applications to use larger color- and  pair-
+       numbers.
+
+       The <STRONG>reset_color_pairs</STRONG> function is an extension of ncurses.

+       be  compiled  into  the terminfo description, i.e., via the terminfo or
+       termcap interfaces.  Normally these names are available for use,  since

+       The <STRONG>get_wch</STRONG>, <STRONG>wget_wch</STRONG>, <STRONG>mvget_wch</STRONG>, and <STRONG>mvwget_wch</STRONG> functions read a char-
+       acter  from  the terminal associated with the current or specified win-
+       dow.  In no-delay mode, if no input is waiting, the value  <STRONG>ERR</STRONG>  is  re-
+       turned.   In delay mode, the program waits until the system passes text
+       through to the program.  Depending on the setting of  <STRONG>cbreak</STRONG>,  this  is
+       after one character (cbreak mode), or after the first newline (nocbreak
+       mode).  In half-delay mode, the program waits until the  user  types  a
+       character or the specified timeout interval has elapsed.
+
+       Unless  <STRONG>noecho</STRONG> has been set, these routines echo the character into the
+       designated window.
+
+       If the window is not a pad and has been moved  or  modified  since  the
+       last call to <STRONG>wrefresh</STRONG>, <STRONG>wrefresh</STRONG> will be called before another character
+       is read.
+
+       If <STRONG>keypad</STRONG> is enabled, these functions respond  to  the  pressing  of  a
+       function key by setting the object pointed to by <EM>wch</EM> to the keycode as-
+       signed to the function key, and returning <STRONG>KEY_CODE_YES</STRONG>.  If a character
+       (such  as  escape) that could be the beginning of a function key is re-
+       ceived, curses sets a timer.  If the remainder of the sequence does ar-
+       rive  within  the designated time, curses passes through the character;
+       otherwise, curses returns the function key  value.   For  this  reason,
+       many  terminals  experience a delay between the time a user presses the
+       escape key and the time the escape is returned to the program.
+
+       The keycodes returned by these functions are the same as those returned
+       by <STRONG>wgetch</STRONG>:
+
+       <STRONG>o</STRONG>   The  predefined  function  keys  are listed in <STRONG>&lt;curses.h&gt;</STRONG> as macros
+           with values outside the range of 8-bit characters.  Their names be-
+           gin with <STRONG>KEY_</STRONG>.
+
+       <STRONG>o</STRONG>   Other  (user-defined)  function keys which may be defined using <STRONG>de-</STRONG>
+           <STRONG><A HREF="define_key.3x.html">fine_key(3x)</A></STRONG> have no names, but also are expected  to  have  values
+           outside the range of 8-bit characters.
+
+
+</PRE><H3><a name="h3-unget_wch">unget_wch</a></H3><PRE>
+       The <STRONG>unget_wch</STRONG> function pushes the wide character <EM>wch</EM> back onto the head
+       of the input queue, so the wide character is returned by the next  call
+       to  <STRONG>get_wch</STRONG>.  The pushback of one character is guaranteed.  If the pro-
+       gram calls <STRONG>unget_wch</STRONG> too many times  without  an  intervening  call  to
+       <STRONG>get_wch</STRONG>, the operation may fail.
+
+       Unlike <STRONG>ungetch</STRONG> and <STRONG>wgetch</STRONG>, <STRONG>unget_wch</STRONG> cannot distinguish special charac-
+       ters returned by <STRONG>wget_wch</STRONG> from ordinary characters.  An application can
+       push  special  keys  which it may read via <STRONG>wget_wch</STRONG> by checking for the
+       <STRONG>KEY_CODE_YES</STRONG> result, and using <STRONG>ungetch</STRONG> for those special keys.

+       The header file  <STRONG>&lt;curses.h&gt;</STRONG>  automatically  includes  the  header  file
+       <STRONG>&lt;stdio.h&gt;</STRONG>.
+
+       Applications  should  not  define the escape key by itself as a single-
+       character function.
+
+       When using <STRONG>get_wch</STRONG>, <STRONG>wget_wch</STRONG>, <STRONG>mvget_wch</STRONG>,  or  <STRONG>mvwget_wch</STRONG>,  applications
+       should not use <STRONG>nocbreak</STRONG> mode and <STRONG>echo</STRONG> mode at the same time.  Depending
+       on the state of the tty driver when each character is typed,  the  pro-
+       gram may produce undesirable results.
+
+       All functions except <STRONG>wget_wch</STRONG> and <STRONG>unget_wch</STRONG> may be macros.

+       tion returns <STRONG>ERR</STRONG>.
+
+       Functions  with  a  "mv"  prefix  first perform a cursor movement using

+       The  effect  of  <STRONG>get_wstr</STRONG> is as though a series of calls to <STRONG><A HREF="curs_get_wch.3x.html">get_wch(3x)</A></STRONG>
+       were made, until a newline, other end-of-line, or end-of-file condition
+       is  processed.  An end-of-file condition is represented by <STRONG>WEOF</STRONG>, as de-
+       fined in <STRONG>&lt;wchar.h&gt;</STRONG>.  The newline and end-of-line conditions are  repre-
+       sented  by  the  <STRONG>\n</STRONG>  <STRONG>wchar_t</STRONG>  value.   In all instances, the end of the
+       string is terminated by a null <STRONG>wchar_t</STRONG>.  The routine  places  resulting
+       values in the area pointed to by <EM>wstr</EM>.
+
+       The  user's  erase and kill characters are interpreted.  If keypad mode
+       is on for the window, <STRONG>KEY_LEFT</STRONG> and <STRONG>KEY_BACKSPACE</STRONG>  are  both  considered
+       equivalent to the user's kill character.
+
+       Characters  input  are  echoed  only  if <STRONG>echo</STRONG> is currently on.  In that
+       case, backspace is echoed as deletion of the previous character  (typi-
+       cally a left motion).
+
+       The effect of <STRONG>wget_wstr</STRONG> is as though a series of calls to <STRONG>wget_wch</STRONG> were
+       made.
+
+       The effect of <STRONG>mvget_wstr</STRONG> is as though a call to <STRONG>move</STRONG> and then a  series
+       of calls to <STRONG>get_wch</STRONG> were made.
+
+       The  effect  of <STRONG>mvwget_wstr</STRONG> is as though a call to <STRONG>wmove</STRONG> and then a se-
+       ries of calls to <STRONG>wget_wch</STRONG> were made.
+
+       The <STRONG>getn_wstr</STRONG>, <STRONG>mvgetn_wstr</STRONG>, <STRONG>mvwgetn_wstr</STRONG>, and <STRONG>wgetn_wstr</STRONG> functions  are
+       identical to the <STRONG>get_wstr</STRONG>, <STRONG>mvget_wstr</STRONG>, <STRONG>mvwget_wstr</STRONG>, and <STRONG>wget_wstr</STRONG> func-
+       tions, respectively, except that the <STRONG>*n_*</STRONG> versions read at most <EM>n</EM> char-
+       acters, letting the application prevent overflow of the input buffer.
+
+
+</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
+       Using  <STRONG>get_wstr</STRONG>,  <STRONG>mvget_wstr</STRONG>,  <STRONG>mvwget_wstr</STRONG>, or <STRONG>wget_wstr</STRONG> to read a line
+       that overflows the array pointed to by <STRONG>wstr</STRONG> causes  undefined  results.
+       The use of <STRONG>getn_wstr</STRONG>, <STRONG>mvgetn_wstr</STRONG>, <STRONG>mvwgetn_wstr</STRONG>, or <STRONG>wgetn_wstr</STRONG>, respec-
+       tively, is recommended.
+
+       These functions cannot return <STRONG>KEY_</STRONG> values because there is  no  way  to
+       distinguish a <STRONG>KEY_</STRONG> value from a valid <STRONG>wchar_t</STRONG> value.
+
+       All of these routines except <STRONG>wgetn_wstr</STRONG> may be macros.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       All  of  these  functions return <STRONG>OK</STRONG> upon successful completion.  Other-
+       wise, they return <STRONG>ERR</STRONG>.
+
+       Functions using a window parameter return an error if it is null.
+
+              <STRONG>wgetn_wstr</STRONG>
+                   returns an error if the associated call to <STRONG>wget_wch</STRONG> failed.
+
+       Functions with a "mv" prefix first  perform  a  cursor  movement  using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       These functions are described in The Single Unix Specification, Version
+       2.   No  error conditions are defined.  This implementation returns <STRONG>ERR</STRONG>
+       if the window pointer is null, or if the lower-level <STRONG>wget_wch</STRONG> call  re-
+       turns  an <STRONG>ERR</STRONG>.  In the latter case, an <STRONG>ERR</STRONG> return without other data is
+       treated as an end-of-file condition, and the returned array contains  a
+       <STRONG>WEOF</STRONG> followed by a null <STRONG>wchar_t</STRONG>.
+
+       X/Open curses documented these functions to pass an array of <STRONG>wchar_t</STRONG> in
+       1997, but that was an error because of this part of the description:
+
+              The effect of <STRONG>get_wstr</STRONG> is as though a series of calls to <STRONG>get_wch</STRONG>
+              were  made, until a newline character, end-of-line character, or
+              end-of-file character is processed.
+
+       The latter function <EM>get</EM><STRONG>_</STRONG><EM>wch</EM> can return a negative value, while  <STRONG>wchar_t</STRONG>
+       is  a  unsigned  type.  All of the vendors implement this using <STRONG>wint_t</STRONG>,
+       following the standard.
+
+       X/Open Curses, Issue 7 (2009) is unclear regarding whether  the  termi-
+       nating <EM>null</EM> <STRONG>wchar_t</STRONG> value is counted in the length parameter <EM>n</EM>.  X/Open
+       Curses, Issue 7 revised the corresponding description  of  <STRONG>wgetnstr</STRONG>  to
+       address this issue.  The unrevised description of <STRONG>wget_nwstr</STRONG> can be in-
+       terpreted either way.  This implementation counts the terminator in the
+       length.
+
+       X/Open  Curses  does  not specify what happens if the length <EM>n</EM> is nega-
+       tive.
+
+       <STRONG>o</STRONG>   For analogy with <STRONG>wgetnstr</STRONG>, ncurses  6.2  uses  a  limit  (based  on
+           <STRONG>LINE_MAX</STRONG>).
+
+       <STRONG>o</STRONG>   Some  other  implementations (such as Solaris xcurses) do the same,
+           while others (PDCurses) do not allow this.
+
+       <STRONG>o</STRONG>   NetBSD 7 curses imitates ncurses 6.1 in this regard, treating a  <STRONG>-1</STRONG>
+           as an indefinite number of characters.

+       <STRONG>o</STRONG>   color pair (at least 16 bits,  inferred  from  the  <STRONG>unsigned</STRONG>  <STRONG>short</STRONG>
+           type).
+
+       The non-spacing characters are optional, in the sense that zero or more
+       may be stored in a <STRONG>cchar_t</STRONG>.  XOpen/Curses specifies a limit:
+
+           Implementations may limit the number of non-spacing characters that
+           can  be  associated with a spacing character, provided any limit is
+           at least 5.
+
+       The Unix implementations at the time follow that limit:
+
+       <STRONG>o</STRONG>   AIX 4 and OSF1 4 use the same declaration with an array of  5  non-
+           spacing characters <EM>z</EM> and a single spacing character <EM>c</EM>.
+
+       <STRONG>o</STRONG>   HP-UX 10  uses  an  opaque  structure with 28 bytes, which is large
+           enough for the 6 <STRONG>wchar_t</STRONG> values.
+
+       <STRONG>o</STRONG>   Solaris <EM>xpg4</EM> curses uses a single array of 6 <STRONG>wchar_t</STRONG> values.
+
+       This implementation's <STRONG>cchar_t</STRONG> was defined in 1995 using <STRONG>5</STRONG> for the total
+       of  spacing and non-spacing characters (<STRONG>CCHARW_MAX</STRONG>).  That was probably
+       due to a misreading of the  AIX 4  header  files,  because  the  X/Open
+       Curses  document  was  not generally available at that time.  Later (in
+       2002), this detail was  overlooked  when  beginning  to  implement  the
+       functions using the structure.
+
+       In  practice, even four non-spacing characters may seem enough.  X/Open
+       Curses documents possible uses for  non-spacing  characters,  including
+       using  them  for ligatures between characters (a feature apparently not
+       supported by any curses implementation).  Unicode does  not  limit  the
+       (analogous) number of combining characters, so some applications may be
+       affected.

+       The <STRONG>getch</STRONG>, <STRONG>wgetch</STRONG>, <STRONG>mvgetch</STRONG> and <STRONG>mvwgetch</STRONG>, routines read a character from
+       the window.  In no-delay mode, if no input is waiting, the value <STRONG>ERR</STRONG> is
+       returned.  In delay mode, the program waits  until  the  system  passes
+       text  through to the program.  Depending on the setting of <STRONG>cbreak</STRONG>, this
+       is after one character  (cbreak  mode),  or  after  the  first  newline
+       (nocbreak mode).  In half-delay mode, the program waits until a charac-
+       ter is typed or the specified timeout has been reached.
+
+       If <STRONG>echo</STRONG> is enabled, and the window is not a  pad,  then  the  character
+       will also be echoed into the designated window according to the follow-
+       ing rules:
+
+       <STRONG>o</STRONG>   If the character is the current erase  character,  left  arrow,  or
+           backspace,  the  cursor  is  moved  one  space to the left and that
+           screen position is erased as if <STRONG>delch</STRONG> had been called.
+
+       <STRONG>o</STRONG>   If the character value is any other <STRONG>KEY_</STRONG> define, the user is alert-
+           ed with a <STRONG>beep</STRONG> call.
+
+       <STRONG>o</STRONG>   If  the character is a carriage-return, and if <STRONG>nl</STRONG> is enabled, it is
+           translated to a line-feed after echoing.
+
+       <STRONG>o</STRONG>   Otherwise the character is simply output to the screen.
+
+       If the window is not a pad, and it has been moved or modified since the
+       last call to <STRONG>wrefresh</STRONG>, <STRONG>wrefresh</STRONG> will be called before another character
+       is read.
+
+
+</PRE><H3><a name="h3-Keypad-mode">Keypad mode</a></H3><PRE>
+       If <STRONG>keypad</STRONG> is <STRONG>TRUE</STRONG>, and a function key is pressed, the  token  for  that
+       function key is returned instead of the raw characters:
+
+       <STRONG>o</STRONG>   The  predefined  function  keys  are listed in <STRONG>&lt;curses.h&gt;</STRONG> as macros
+           with values outside the range of 8-bit characters.  Their names be-
+           gin with <STRONG>KEY_</STRONG>.
+
+       <STRONG>o</STRONG>   Other  (user-defined)  function keys which may be defined using <STRONG>de-</STRONG>
+           <STRONG><A HREF="define_key.3x.html">fine_key(3x)</A></STRONG> have no names, but also are expected  to  have  values
+           outside the range of 8-bit characters.
+
+       Thus,  a  variable  intended to hold the return value of a function key
+       must be of short size or larger.
+
+       When a character that could be the beginning of a function key  is  re-
+       ceived  (which, on modern terminals, means an escape character), <STRONG>curses</STRONG>
+       sets a timer.  If the remainder of the sequence does not come in within
+       the  designated  time,  the character is passed through; otherwise, the
+       function key value is returned.  For this reason, many terminals  expe-
+       rience  a  delay between the time a user presses the escape key and the
+       escape is returned to the program.
+
+       In <STRONG>ncurses</STRONG>, the timer normally expires after the value in <STRONG>ESCDELAY</STRONG> (see
+       <STRONG><A HREF="curs_variables.3x.html">curs_variables(3x)</A></STRONG>).   If <STRONG>notimeout</STRONG> is <STRONG>TRUE</STRONG>, the timer does not expire;
+       it is an infinite (or very large) value.  Because function keys usually
+       begin  with an escape character, the terminal may appear to hang in no-
+       timeout mode after  pressing  the  escape  key  until  another  key  is
+       pressed.

+       The  <STRONG>ungetch</STRONG> routine places <EM>ch</EM> back onto the input queue to be returned
+       by the next call to <STRONG>wgetch</STRONG>.  There is just one input queue for all win-
+       dows.

+
+       <STRONG>o</STRONG>   Not all of these are necessarily supported on any particular termi-
+           nal.
+
+       <STRONG>o</STRONG>   The  naming  convention  may  seem obscure, with some apparent mis-
+           spellings (such as "RSUME" for "resume").  The names correspond  to
+           the  long  terminfo capability names for the keys, and were defined
+           long ago, in the 1980s.

+       Use of the escape key by a programmer for a single  character  function
+       is  discouraged, as it will cause a delay of up to one second while the
+       keypad code looks for a following function-key sequence.
+
+       Some keys may be the same as commonly used control keys, e.g.,  <STRONG>KEY_EN-</STRONG>
+       <STRONG>TER</STRONG>  versus control/M, <STRONG>KEY_BACKSPACE</STRONG> versus control/H.  Some curses im-
+       plementations may differ according to whether they treat these  control
+       keys  specially  (and ignore the terminfo), or use the terminfo defini-
+       tions.  <STRONG>Ncurses</STRONG> uses the terminfo definition.  If it says that  <STRONG>KEY_EN-</STRONG>
+       <STRONG>TER</STRONG> is control/M, <STRONG>getch</STRONG> will return <STRONG>KEY_ENTER</STRONG> when you press control/M.
+
+       Generally,  <STRONG>KEY_ENTER</STRONG> denotes the character(s) sent by the <EM>Enter</EM> key on
+       the numeric keypad:
+
+       <STRONG>o</STRONG>   the terminal description lists the most useful keys,
+
+       <STRONG>o</STRONG>   the <EM>Enter</EM> key on the regular keyboard is  already  handled  by  the
+           standard ASCII characters for carriage-return and line-feed,
+
+       <STRONG>o</STRONG>   depending on whether <STRONG>nl</STRONG> or <STRONG>nonl</STRONG> was called, pressing "Enter" on the
+           regular keyboard may return either a carriage-return or  line-feed,
+           and finally
+
+       <STRONG>o</STRONG>   "Enter or send" is the standard description for this key.
+
+       When   using   <STRONG>getch</STRONG>,  <STRONG>wgetch</STRONG>,  <STRONG>mvgetch</STRONG>,  or  <STRONG>mvwgetch</STRONG>,  nocbreak  mode
+       (<STRONG>nocbreak</STRONG>) and echo mode (<STRONG>echo</STRONG>) should not be used at  the  same  time.
+       Depending  on the state of the tty driver when each character is typed,
+       the program may produce undesirable results.
+
+       Note that <STRONG>getch</STRONG>, <STRONG>mvgetch</STRONG>, and <STRONG>mvwgetch</STRONG> may be macros.
+
+       Historically, the set of keypad macros was largely defined by  the  ex-
+       tremely  function-key-rich  keyboard of the AT&amp;T 7300, aka 3B1, aka Sa-
+       fari 4.  Modern personal computers usually have only a small subset  of
+       these.   IBM  PC-style  consoles  typically  support  little  more than
+       <STRONG>KEY_UP</STRONG>, <STRONG>KEY_DOWN</STRONG>, <STRONG>KEY_LEFT</STRONG>, <STRONG>KEY_RIGHT</STRONG>,  <STRONG>KEY_HOME</STRONG>,  <STRONG>KEY_END</STRONG>,  <STRONG>KEY_NPAGE</STRONG>,
+       <STRONG>KEY_PPAGE</STRONG>,  and  function  keys  1  through 12.  The Ins key is usually
+       mapped to <STRONG>KEY_IC</STRONG>.

+       The *get* functions are described in the XSI Curses standard, Issue  4.
+       They  read  single-byte  characters  only.  The standard specifies that
+       they return <STRONG>ERR</STRONG> on failure, but specifies no error conditions.
+
+       The echo behavior of these functions on  input  of  <STRONG>KEY_</STRONG>  or  backspace
+       characters  was not specified in the SVr4 documentation.  This descrip-
+       tion is adopted from the XSI Curses standard.
+
+       The behavior of <STRONG>getch</STRONG> and friends in the presence of handled signals is
+       unspecified in the SVr4 and XSI Curses documentation.  Under historical
+       curses implementations, it varied depending on  whether  the  operating
+       system's  implementation of handled signal receipt interrupts a <STRONG>read(2)</STRONG>
+       call in progress or not, and also (in some  implementations)  depending
+       on whether an input timeout or non-blocking mode has been set.
+
+       <STRONG>KEY_MOUSE</STRONG> is mentioned in XSI Curses, along with a few related terminfo
+       capabilities, but no higher-level functions use the feature.   The  im-
+       plementation in ncurses is an extension.
+
+       <STRONG>KEY_RESIZE</STRONG> is an extension first implemented for ncurses.  NetBSD curs-
+       es later added this extension.
+
+       Programmers concerned about portability should be prepared  for  either
+       of  two  cases: (a) signal receipt does not interrupt <STRONG>getch</STRONG>; (b) signal
+       receipt interrupts <STRONG>getch</STRONG> and causes it to return <STRONG>ERR</STRONG> with <STRONG>errno</STRONG> set  to
+       <STRONG>EINTR</STRONG>.
+
+       The  <STRONG>has_key</STRONG> function is unique to <STRONG>ncurses</STRONG>.  We recommend that any code
+       using it be conditionalized on the <STRONG>NCURSES_VERSION</STRONG> feature macro.

+       The function <STRONG>getstr</STRONG> is equivalent to a series of calls to <STRONG>getch</STRONG>,  until
+       a  newline or carriage return is received (the terminating character is
+       not included in the returned string).  The resulting value is placed in
+       the area pointed to by the character pointer <EM>str</EM>, followed by a NUL.
+
+       The  <STRONG>getnstr</STRONG>  function reads from the <EM>stdscr</EM> default window.  The other
+       functions, such as <STRONG>wgetnstr</STRONG>, read from the window given as a parameter.
+
+       <STRONG>getnstr</STRONG> reads at most <EM>n</EM> characters, thus preventing a possible overflow
+       of  the input buffer.  Any attempt to enter more characters (other than
+       the terminating newline or carriage return) causes  a  beep.   Function
+       keys also cause a beep and are ignored.
+
+       The user's <EM>erase</EM> and <EM>kill</EM> characters are interpreted:
+
+       <STRONG>o</STRONG>   The  <EM>erase</EM>  character (e.g., <STRONG>^H</STRONG>) erases the character at the end of
+           the buffer, moving the cursor to the left.
+
+           If <EM>keypad</EM> mode is on for the window, <STRONG>KEY_LEFT</STRONG> and <STRONG>KEY_BACKSPACE</STRONG> are
+           both considered equivalent to the user's erase character.
+
+       <STRONG>o</STRONG>   The <EM>kill</EM> character (e.g., <STRONG>^U</STRONG>) erases the entire buffer, leaving the
+           cursor at the beginning of the buffer.
+
+       Characters input are echoed only if <STRONG>echo</STRONG>  is  currently  on.   In  that
+       case,  backspace is echoed as deletion of the previous character (typi-
+       cally a left motion).
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       All routines return the integer <STRONG>ERR</STRONG> upon failure and an <STRONG>OK</STRONG> (SVr4 speci-
+       fies  only  "an  integer value other than <STRONG>ERR</STRONG>") upon successful comple-
+       tion.
+
+       X/Open defines no error conditions.
+
+       In this implementation, these functions return an error if  the  window
+       pointer is null, or if its timeout expires without having any data.
+
+       This  implementation  provides an extension as well.  If a <STRONG>SIGWINCH</STRONG> in-
+       terrupts the function, it will return <STRONG>KEY_RESIZE</STRONG> rather than <STRONG>OK</STRONG> or <STRONG>ERR</STRONG>.
+
+       Functions with a "mv" prefix first  perform  a  cursor  movement  using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.

+       These functions are described in the  XSI  Curses  standard,  Issue  4.
+       They  read  single-byte  characters only.  The standard does not define
+       any error conditions.  This implementation returns <STRONG>ERR</STRONG>  if  the  window
+       pointer is null, or if the lower-level <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG> call returns an <STRONG>ERR</STRONG>.
+
+       SVr3  and  early  SVr4  curses  implementations did not reject function
+       keys; the SVr4.0 documentation claimed that  "special  keys"  (such  as
+       function  keys, "home" key, "clear" key, <EM>etc</EM>.) are "interpreted", with-
+       out giving details.  It lied.  In fact, the "character" value  appended
+       to  the  string by those implementations was predictable but not useful
+       (being, in fact, the low-order eight bits of the key's KEY_ value).
+
+       The functions <STRONG>getnstr</STRONG>, <STRONG>mvgetnstr</STRONG>, and <STRONG>mvwgetnstr</STRONG> were present  but  not
+       documented in SVr4.
+
+       X/Open Curses, Issue 5 (2007) stated that these functions "read at most
+       <EM>n</EM> bytes" but did not state whether the terminating NUL  is  counted  in
+       that  limit.   X/Open  Curses,  Issue 7 (2009) changed that to say they
+       "read at most <EM>n</EM>-1 bytes" to allow for the terminating NUL.  As of 2018,
+       some implementations do, some do not count it:
+
+       <STRONG>o</STRONG>   ncurses  6.1  and PDCurses do not count the NUL in the given limit,
+           while
+
+       <STRONG>o</STRONG>   Solaris SVr4 and NetBSD curses count the NUL as part of the limit.
+
+       <STRONG>o</STRONG>   Solaris xcurses provides both:  its  wide-character  <STRONG>wget_nstr</STRONG>  re-
+           serves a NUL, but its <STRONG>wgetnstr</STRONG> does not count the NUL consistently.
+
+       In SVr4 curses, a negative value of <EM>n</EM> tells <STRONG>wgetnstr</STRONG> to assume that the
+       caller's buffer is large enough to hold the result, i.e., to  act  like
+       <STRONG>wgetstr</STRONG>.   X/Open  Curses does not mention this (or anything related to
+       negative or zero values of <EM>n</EM>), however  most  implementations  use  the
+       feature, with different limits:
+
+       <STRONG>o</STRONG>   Solaris  SVr4  curses  and  PDCurses limit the result to 255 bytes.
+           Other Unix systems than Solaris are likely to use the same limit.
+
+       <STRONG>o</STRONG>   Solaris xcurses limits the result to <STRONG>LINE_MAX</STRONG> bytes.
+
+       <STRONG>o</STRONG>   NetBSD 7 assumes no particular limit for the result  from  <STRONG>wgetstr</STRONG>.
+           However,  it  limits  the <STRONG>wgetnstr</STRONG> parameter <EM>n</EM> to ensure that it is
+           greater than zero.
+
+           A comment in NetBSD's source code states that this is specified  in
+           SUSv2.
+
+       <STRONG>o</STRONG>   ncurses  (before  6.2)  assumes  no particular limit for the result
+           from <STRONG>wgetstr</STRONG>, and treats the <EM>n</EM>  parameter  of  <STRONG>wgetnstr</STRONG>  like  SVr4
+           curses.
+
+       <STRONG>o</STRONG>   ncurses  6.2  uses  <STRONG>LINE_MAX</STRONG>,  or a larger (system-dependent) value
+           which the <STRONG>sysconf</STRONG> function may provide.   If  neither  <STRONG>LINE_MAX</STRONG>  or
+           <STRONG>sysconf</STRONG>  is available, ncurses uses the POSIX value for <STRONG>LINE_MAX</STRONG> (a
+           2048 byte limit).  In either case, it reserves a byte for the  ter-
+           minating NUL.
+
+       Although  <STRONG>getnstr</STRONG>  is equivalent to a series of calls to <STRONG>getch</STRONG>, it also
+       makes changes to the curses modes to allow simple editing of the  input
+       buffer:
+
+       <STRONG>o</STRONG>   <STRONG>getnstr</STRONG>  saves  the  current  value of the <STRONG>nl</STRONG>, <STRONG>echo</STRONG>, <STRONG>raw</STRONG> and <STRONG>cbreak</STRONG>
+           modes, and sets <STRONG>nl</STRONG>, <STRONG>noecho</STRONG>, <STRONG>noraw</STRONG>, and <STRONG>cbreak</STRONG>.
+
+           <STRONG>getnstr</STRONG> handles the echoing of characters, rather than  relying  on
+           the caller to set an appropriate mode.
+
+       <STRONG>o</STRONG>   It  also  obtains  the <EM>erase</EM> and <EM>kill</EM> characters from <STRONG>erasechar</STRONG> and
+           <STRONG>killchar</STRONG>, respectively.
+
+       <STRONG>o</STRONG>   On return, <STRONG>getnstr</STRONG> restores the modes to their previous values.
+
+       Other implementations differ in their treatment of special characters:
+
+       <STRONG>o</STRONG>   While they may set the <EM>echo</EM> mode, other implementations do not mod-
+           ify  the  <EM>raw</EM> mode, They may take the <EM>cbreak</EM> mode set by the caller
+           into account when deciding whether to handle echoing within <STRONG>getnstr</STRONG>
+           or as a side-effect of the <STRONG>getch</STRONG> calls.
+
+       <STRONG>o</STRONG>   The original ncurses (as <EM>pcurses</EM> in 1986) set <STRONG>noraw</STRONG> and <STRONG>cbreak</STRONG> when
+           accepting input for <STRONG>getnstr</STRONG>.  That may have been done to make func-
+           tion- and cursor-keys work; it is not necessary with ncurses.
+
+           Since  1995, ncurses has provided signal handlers for INTR and QUIT
+           (e.g., <STRONG>^C</STRONG> or <STRONG>^\</STRONG>).  With the <STRONG>noraw</STRONG> and <STRONG>cbreak</STRONG>  settings,  those  may
+           catch  a  signal  and stop the program, where other implementations
+           allow one to enter those characters in the buffer.
+
+       <STRONG>o</STRONG>   Starting in 2021 (ncurses 6.3), <STRONG>getnstr</STRONG> sets <STRONG>raw</STRONG>, rather than <STRONG>noraw</STRONG>
+           and  <STRONG>cbreak</STRONG> for better compatibility with SVr4-curses, e.g., allow-
+           ing one to enter a <STRONG>^C</STRONG> into the buffer.

+       The <STRONG>getyx</STRONG> macro places the current cursor position of the given  window

+
+       If  <EM>win</EM>  is  a  subwindow,  the  <STRONG>getparyx</STRONG>  macro  places  the beginning
+       coordinates of the subwindow relative to the  parent  window  into  two
+       integer variables <EM>y</EM> and <EM>x</EM>.  Otherwise, <STRONG>-1</STRONG> is placed into <EM>y</EM> and <EM>x</EM>.
+
+       Like  <STRONG>getyx</STRONG>,  the  <STRONG>getbegyx</STRONG>  and  <STRONG>getmaxyx</STRONG>  macros  store  the  current
+       beginning coordinates and size of the specified window.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       The return values of these macros are undefined (i.e., they should  not
+       be used as the right-hand side of assignment statements).
+
+
+</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
+       All  of these interfaces are macros.  A "<STRONG>&amp;</STRONG>" is not necessary before the
+       variables <EM>y</EM> and <EM>x</EM>.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       The <STRONG>getyx</STRONG>, <STRONG>getparyx</STRONG>, <STRONG>getbegyx</STRONG> and <STRONG>getmaxyx</STRONG> macros are described in  the
+       XSI Curses standard, Issue 4.
+
+       This  implementation also provides functions <STRONG>getbegx</STRONG>, <STRONG>getbegy</STRONG>, <STRONG>getcurx</STRONG>,
+       <STRONG>getcury</STRONG>, <STRONG>getmaxx</STRONG>, <STRONG>getmaxy</STRONG>, <STRONG>getparx</STRONG> and <STRONG>getpary</STRONG> for  compatibility  with
+       older versions of curses.
+
+       Although  X/Open  Curses  does  not  address this, many implementations
+       provide members of the WINDOW structure containing values corresponding
+       to  these  macros.  For best portability, do not rely on using the data
+       in WINDOW, since some implementations make WINDOW opaque (do not  allow
+       direct use of its members).
+
+       Besides the problem of opaque structures, the data stored in like-named
+       members may not have like-values  in  different  implementations.   For
+       example,  the  WINDOW._maxx and WINDOW._maxy values in ncurses have (at
+       least  since  release  1.8.1)  differed  by   one   from   some   other
+       implementations.   The  difference  is  hidden  by  means  of the macro
+       <STRONG>getmaxyx</STRONG>.

+       These functions are described in the XSI Curses standard, Issue 4.
+
+       Very  old systems (before standardization) provide a different function
+       with the same name:
+
+       <STRONG>o</STRONG>   The <STRONG>winch</STRONG> function was part of the  original  BSD  curses  library,
+           which   stored   a  7-bit  character  combined  with  the  <EM>standout</EM>
+           attribute.
+
+           In BSD curses, <STRONG>winch</STRONG> returned only the character  (as  an  integer)
+           with the <EM>standout</EM> attribute removed.
+
+       <STRONG>o</STRONG>   System  V  curses  added support for several video attributes which
+           could be combined with characters in the window.
+
+           Reflecting this improvement, the function was altered to return the
+           character combined with all video attributes in a <STRONG>chtype</STRONG> value.
+
+       X/Open Curses does not specify the size and layout of attributes, color
+       and character values in <STRONG>chtype</STRONG>; it is  implementation-dependent.   This
+       implementation  uses 8 bits for character values.  An application using
+       more bits,  e.g.,  a  Unicode  value,  should  use  the  wide-character
+       equivalents to these functions.

+       These  routines  return  a  NULL-terminated array of <STRONG>chtype</STRONG> quantities,
+       starting at the current cursor position in the named window and  ending
+       at  the  right  margin of the window.  The four functions with <EM>n</EM> as the
+       last argument, return a leading substring at  most  <EM>n</EM>  characters  long
+       (exclusive of the trailing (chtype)0).  Constants defined in <STRONG>&lt;curses.h&gt;</STRONG>
+       can be used with the <STRONG>&amp;</STRONG> (logical AND) operator to extract the  character
+       or   the   attribute   alone  from  any  position  in  the  <EM>chstr</EM>  [see
+       <STRONG><A HREF="curs_inch.3x.html">curs_inch(3x)</A></STRONG>].
+

+       other than <STRONG>ERR</STRONG> upon successful completion (the number of characters re-
+       trieved, exclusive of the trailing 0).
+
+       X/Open Curses defines no error conditions.  In this implementation:
+
+       <STRONG>o</STRONG>   If the <EM>win</EM> parameter is null, an error is returned,
+
+       <STRONG>o</STRONG>   If the <EM>chstr</EM> parameter is null, an error is returned,
+
+       Functions with a "mv" prefix first  perform  a  cursor  movement  using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.
+
+
+</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
+       Note that all routines except <STRONG>winchnstr</STRONG> may be macros.  SVr4  does  not

+       <STRONG>initscr</STRONG> is normally the first <STRONG>curses</STRONG> routine to call when  initializing
+       a  program.   A few special routines sometimes need to be called before
+       it; these are <STRONG><A HREF="curs_slk.3x.html">slk_init(3x)</A></STRONG>, <STRONG>filter</STRONG>, <STRONG>ripoffline</STRONG>, <STRONG>use_env</STRONG>.  For multiple-
+       terminal applications, <STRONG>newterm</STRONG> may be called before <STRONG>initscr</STRONG>.
+
+       The initscr code determines the terminal type and initializes all <STRONG>curs-</STRONG>
+       <STRONG>es</STRONG> data structures.  <STRONG>initscr</STRONG> also causes the first call to  <STRONG><A HREF="curscurs_refresh.3x.html">refresh(3x)</A></STRONG>
+       to  clear  the  screen.  If errors occur, <STRONG>initscr</STRONG> writes an appropriate
+       error message to standard error and exits; otherwise, a pointer is  re-
+       turned to <STRONG>stdscr</STRONG>.
+
+
+</PRE><H3><a name="h3-newterm">newterm</a></H3><PRE>
+       A program that outputs to more than one terminal should use the <STRONG>newterm</STRONG>
+       routine for each terminal instead of <STRONG>initscr</STRONG>.  A program that needs  to
+       inspect capabilities, so it can continue to run in a line-oriented mode
+       if the terminal cannot support a screen-oriented  program,  would  also
+       use <STRONG>newterm</STRONG>.  The routine <STRONG>newterm</STRONG> should be called once for each termi-
+       nal.  It returns a variable of type <STRONG>SCREEN</STRONG> <STRONG>*</STRONG> which should be saved as a
+       reference to that terminal.  <STRONG>newterm</STRONG>'s arguments are
+
+       <STRONG>o</STRONG>   the <EM>type</EM> of the terminal to be used in place of <STRONG>$TERM</STRONG>,
+
+       <STRONG>o</STRONG>   a file pointer for output to the terminal, and
+
+       <STRONG>o</STRONG>   another file pointer for input from the terminal
+
+       If the <EM>type</EM> parameter is <STRONG>NULL</STRONG>, <STRONG>$TERM</STRONG> will be used.
+
+
+</PRE><H3><a name="h3-endwin">endwin</a></H3><PRE>
+       The  program  must also call <STRONG>endwin</STRONG> for each terminal being used before
+       exiting from <STRONG>curses</STRONG>.  If <STRONG>newterm</STRONG> is called more than once for the  same
+       terminal, the first terminal referred to must be the last one for which
+       <STRONG>endwin</STRONG> is called.
+
+       A program should always call <STRONG>endwin</STRONG> before  exiting  or  escaping  from
+       <STRONG>curses</STRONG> mode temporarily.  This routine
+
+       <STRONG>o</STRONG>   resets colors to correspond with the default color pair 0,
+
+       <STRONG>o</STRONG>   moves the cursor to the lower left-hand corner of the screen,
+
+       <STRONG>o</STRONG>   clears  the  remainder of the line so that it uses the default col-
+           ors,
+
+       <STRONG>o</STRONG>   sets the cursor to normal visibility (see <STRONG><A HREF="curs_kernel.3x.html">curs_set(3x)</A></STRONG>),
+
+       <STRONG>o</STRONG>   stops cursor-addressing mode using the <EM>exit</EM><STRONG>_</STRONG><EM>ca</EM><STRONG>_</STRONG><EM>mode</EM> terminal  capa-
+           bility,
+
+       <STRONG>o</STRONG>   restores tty modes (see <STRONG><A HREF="curs_kernel.3x.html">reset_shell_mode(3x)</A></STRONG>).
+
+       Calling <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG> or <STRONG><A HREF="curs_refresh.3x.html">doupdate(3x)</A></STRONG> after a temporary escape causes the
+       program to resume visual mode.
+
+
+</PRE><H3><a name="h3-isendwin">isendwin</a></H3><PRE>
+       The <STRONG>isendwin</STRONG> routine returns <STRONG>TRUE</STRONG> if <STRONG>endwin</STRONG> has been called without any
+       subsequent calls to <STRONG>wrefresh</STRONG>, and <STRONG>FALSE</STRONG> otherwise.
+
+
+</PRE><H3><a name="h3-set_term">set_term</a></H3><PRE>
+       The  <STRONG>set_term</STRONG>  routine  is  used to switch between different terminals.
+       The screen reference <EM>new</EM> becomes the new current terminal.  The  previ-
+       ous  terminal  is  returned  by  the routine.  This is the only routine
+       which manipulates <STRONG>SCREEN</STRONG> pointers; all other routines affect  only  the
+       current terminal.
+
+
+</PRE><H3><a name="h3-delscreen">delscreen</a></H3><PRE>
+       The  <STRONG>delscreen</STRONG>  routine  frees  storage associated with the <STRONG>SCREEN</STRONG> data
+       structure.  The <STRONG>endwin</STRONG> routine does not do this, so <STRONG>delscreen</STRONG> should be
+       called after <STRONG>endwin</STRONG> if a particular <STRONG>SCREEN</STRONG> is no longer needed.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       <STRONG>endwin</STRONG> returns the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> upon successful com-
+       pletion.
+
+       Routines that return pointers always return <STRONG>NULL</STRONG> on error.
+
+       X/Open defines no error conditions.  In this implementation
+
+       <STRONG>o</STRONG>   <STRONG>endwin</STRONG> returns an error if the terminal was not initialized.
+
+       <STRONG>o</STRONG>   <STRONG>newterm</STRONG> returns an error if it cannot allocate the data  structures
+           for  the  screen,  or  for the top-level windows within the screen,
+           i.e., <STRONG>curscr</STRONG>, <STRONG>newscr</STRONG>, or <STRONG>stdscr</STRONG>.
+
+       <STRONG>o</STRONG>   <STRONG>set_term</STRONG> returns no error.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       These functions were described in the XSI Curses standard, Issue 4.  As
+       of 2015, the current document is X/Open Curses, Issue 7.
+
+
+</PRE><H3><a name="h3-Differences">Differences</a></H3><PRE>
+       X/Open  specifies that portable applications must not call <STRONG>initscr</STRONG> more
+       than once:
+
+       <STRONG>o</STRONG>   The portable way to use <STRONG>initscr</STRONG> is once only,  using  <STRONG>refresh</STRONG>  (see
+           <STRONG><A HREF="curs_refresh.3x.html">curs_refresh(3x)</A></STRONG>) to restore the screen after <STRONG>endwin</STRONG>.
+
+       <STRONG>o</STRONG>   This implementation allows using <STRONG>initscr</STRONG> after <STRONG>endwin</STRONG>.
+
+       Old versions of curses, e.g., BSD 4.4, would return a null pointer from
+       <STRONG>initscr</STRONG> when an error is detected, rather than exiting.  It is safe but
+       redundant to check the return value of <STRONG>initscr</STRONG> in XSI Curses.
+
+       Calling  <STRONG>endwin</STRONG>  does not dispose of the memory allocated in <STRONG>initscr</STRONG> or
+       <STRONG>newterm</STRONG>.  Deleting a <STRONG>SCREEN</STRONG> provides a way to do this:
+
+       <STRONG>o</STRONG>   X/Open Curses does not say what happens to <STRONG>WINDOW</STRONG>s  when  <STRONG>delscreen</STRONG>
+           "frees  storage associated with the <STRONG>SCREEN</STRONG>" nor does the SVr4 docu-
+           mentation help, adding that it should be called after <STRONG>endwin</STRONG>  if  a
+           <STRONG>SCREEN</STRONG> is no longer needed.
+
+       <STRONG>o</STRONG>   However,  <STRONG>WINDOW</STRONG>s are implicitly associated with a <STRONG>SCREEN</STRONG>.  so that
+           it is reasonable to expect <STRONG>delscreen</STRONG> to deal with these.
+
+       <STRONG>o</STRONG>   SVr4 curses deletes  the  standard  <STRONG>WINDOW</STRONG>  structures  <STRONG>stdscr</STRONG>  and
+           <STRONG>curscr</STRONG>  as  well  as a work area <STRONG>newscr</STRONG>.  SVr4 curses ignores other
+           windows.
+
+       <STRONG>o</STRONG>   Since version 4.0 (1996), ncurses has maintained a list of all win-
+           dows  for  each screen, using that information to delete those win-
+           dows when <STRONG>delscreen</STRONG> is called.
+
+       <STRONG>o</STRONG>   NetBSD copied this feature of ncurses in  2001.   PDCurses  follows
+           the SVr4 model, deleting only the standard <STRONG>WINDOW</STRONG> structures.
+
+
+</PRE><H3><a name="h3-Unset-TERM-Variable">Unset TERM Variable</a></H3><PRE>
+       If  the  TERM variable is missing or empty, <STRONG>initscr</STRONG> uses the value "un-
+       known", which normally corresponds to a terminal entry with the <EM>generic</EM>

+            <EM>to</EM> <EM>signals</EM> ...
+
+       This implementation establishes signal handlers during  initialization,
+       e.g., <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>.  Applications which must handle these signals
+       should set up the corresponding handlers  <EM>after</EM>  initializing  the  li-
+       brary:
+
+       <STRONG>SIGINT</STRONG>
+            The  handler  <EM>attempts</EM> to cleanup the screen on exit.  Although it
+            <EM>usually</EM> works as expected, there are limitations:
+
+            <STRONG>o</STRONG>   Walking the <STRONG>SCREEN</STRONG> list is unsafe, since all  list  management
+                is done without any signal blocking.
+
+            <STRONG>o</STRONG>   On systems which have <STRONG>REENTRANT</STRONG> turned on, <STRONG>set_term</STRONG> uses func-
+                tions which could deadlock or misbehave in other ways.
+
+            <STRONG>o</STRONG>   <STRONG>endwin</STRONG> calls other functions, many of which use stdio or other
+                library functions which are clearly unsafe.
+
+       <STRONG>SIGTERM</STRONG>
+            This  uses  the same handler as <STRONG>SIGINT</STRONG>, with the same limitations.
+            It is not mentioned in X/Open Curses, but  is  more  suitable  for
+            this purpose than <STRONG>SIGQUIT</STRONG> (which is used in debugging).
+
+       <STRONG>SIGTSTP</STRONG>
+            This  handles the <EM>stop</EM> signal, used in job control.  When resuming
+            the process,  this  implementation  discards  pending  input  with
+            <STRONG>flushinput</STRONG>  (see  <STRONG><A HREF="curs_util.3x.html">curs_util(3x)</A></STRONG>), and repaints the screen assuming
+            that it has been completely altered.  It also  updates  the  saved
+            terminal modes with <STRONG>def_shell_mode</STRONG> (see <STRONG><A HREF="curs_kernel.3x.html">curs_kernel(3x)</A></STRONG>).
+
+       <STRONG>SIGWINCH</STRONG>
+            This  handles  the  window-size  changes which were ignored in the
+            standardization efforts.  The handler sets a  (signal-safe)  vari-
+            able  which  is  later  tested in <STRONG>wgetch</STRONG> (see <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG>).  If
+            <STRONG>keypad</STRONG> has been enabled for the corresponding window,  <STRONG>wgetch</STRONG>  re-
+            turns  the  key symbol <STRONG>KEY_RESIZE</STRONG>.  At the same time, <STRONG>wgetch</STRONG> calls
+            <STRONG>resizeterm</STRONG> to adjust the standard screen <STRONG>stdscr</STRONG>, and update  other
+            data such as <STRONG>LINES</STRONG> and <STRONG>COLS</STRONG>.

+       The <STRONG>ncurses</STRONG> library provides several functions which let an application
+       change the way input from the terminal is handled.   Some  are  global,
+       applying to all windows.  Others apply only to a specific window.  Win-
+       dow-specific settings are not automatically applied to new  or  derived
+       windows.   An  application must apply these to each window, if the same
+       behavior is needed.
+
+
+</PRE><H3><a name="h3-cbreak_nocbreak">cbreak/nocbreak</a></H3><PRE>
+       Normally, the tty driver buffers typed characters until  a  newline  or
+       carriage  return  is typed.  The <STRONG>cbreak</STRONG> routine disables line buffering
+       and erase/kill character-processing (interrupt and flow control charac-
+       ters  are  unaffected), making characters typed by the user immediately
+       available to the program.  The <STRONG>nocbreak</STRONG> routine returns the terminal to
+       normal (cooked) mode.
+
+       Initially the terminal may or may not be in <STRONG>cbreak</STRONG> mode, as the mode is
+       inherited; therefore, a program should call <STRONG>cbreak</STRONG> or <STRONG>nocbreak</STRONG>  explic-
+       itly.   Most  interactive  programs  using  <STRONG>curses</STRONG> set the <STRONG>cbreak</STRONG> mode.
+       Note that <STRONG>cbreak</STRONG> overrides <STRONG>raw</STRONG>.  [See <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG> for  a  discussion
+       of how these routines interact with <STRONG>echo</STRONG> and <STRONG>noecho</STRONG>.]
+
+
+</PRE><H3><a name="h3-echo_noecho">echo/noecho</a></H3><PRE>
+       The  <STRONG>echo</STRONG>  and  <STRONG>noecho</STRONG> routines control whether characters typed by the
+       user are echoed by <STRONG><A HREF="curs_getch.3x.html">getch(3x)</A></STRONG> as they are typed.   Echoing  by  the  tty
+       driver  is  always  disabled,  but  initially <STRONG>getch</STRONG> is in echo mode, so
+       characters typed are echoed.  Authors of most interactive programs pre-
+       fer  to do their own echoing in a controlled area of the screen, or not
+       to echo at all, so  they  disable  echoing  by  calling  <STRONG>noecho</STRONG>.   [See
+       <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG>  for  a  discussion  of how these routines interact with
+       <STRONG>cbreak</STRONG> and <STRONG>nocbreak</STRONG>.]
+
+
+</PRE><H3><a name="h3-halfdelay">halfdelay</a></H3><PRE>
+       The <STRONG>halfdelay</STRONG> routine is used for half-delay mode, which is similar  to
+       <STRONG>cbreak</STRONG> mode in that characters typed by the user are immediately avail-
+       able to the program.  However, after blocking for <EM>tenths</EM> tenths of sec-
+       onds,  <STRONG>ERR</STRONG>  is returned if nothing has been typed.  The value of <EM>tenths</EM>
+       must be a number between 1 and 255.  Use <STRONG>nocbreak</STRONG> to  leave  half-delay
+       mode.
+
+
+</PRE><H3><a name="h3-intrflush">intrflush</a></H3><PRE>
+       If  the  <STRONG>intrflush</STRONG> option is enabled (<EM>bf</EM> is <STRONG>TRUE</STRONG>), and an interrupt key
+       is pressed on the keyboard (interrupt, break, quit), all output in  the
+       tty  driver queue will be flushed, giving the effect of faster response
+       to the interrupt, but causing <STRONG>curses</STRONG> to have the wrong idea of what  is
+       on  the screen.  Disabling the option (<EM>bf</EM> is <STRONG>FALSE</STRONG>) prevents the flush.
+       The default for the option is inherited from the tty  driver  settings.
+       The window argument is ignored.
+
+
+</PRE><H3><a name="h3-keypad">keypad</a></H3><PRE>
+       The  <STRONG>keypad</STRONG>  option  enables the keypad of the user's terminal.  If en-
+       abled (<EM>bf</EM> is <STRONG>TRUE</STRONG>), the user can press a function key (such as an arrow
+       key)  and  <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG>  returns a single value representing the function
+       key, as in <STRONG>KEY_LEFT</STRONG>.  If disabled (<EM>bf</EM> is <STRONG>FALSE</STRONG>), <STRONG>curses</STRONG> does not  treat
+       function keys specially and the program has to interpret the escape se-
+       quences itself.  If the keypad in the terminal can be turned  on  (made
+       to  transmit)  and  off  (made to work locally), turning on this option
+       causes the terminal keypad to be turned on when <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG>  is  called.
+       The default value for keypad is <STRONG>FALSE</STRONG>.
+
+
+</PRE><H3><a name="h3-meta">meta</a></H3><PRE>
+       Initially,  whether the terminal returns 7 or 8 significant bits on in-
+       put depends on the control mode of the tty driver [see <STRONG>termios(3)</STRONG>].  To
+       force  8  bits  to be returned, invoke <STRONG>meta</STRONG>(<EM>win</EM>, <STRONG>TRUE</STRONG>); this is equiva-
+       lent, under POSIX, to setting the CS8 flag on the terminal.  To force 7
+       bits to be returned, invoke <STRONG>meta</STRONG>(<EM>win</EM>, <STRONG>FALSE</STRONG>); this is equivalent, under
+       POSIX, to setting the CS7 flag on the terminal.  The  window  argument,
+       <EM>win</EM>, is always ignored.  If the terminfo capabilities <STRONG>smm</STRONG> (meta_on) and
+       <STRONG>rmm</STRONG> (meta_off) are defined for the terminal, <STRONG>smm</STRONG> is sent to the  termi-
+       nal  when  <STRONG>meta</STRONG>(<EM>win</EM>,  <STRONG>TRUE</STRONG>)  is  called  and <STRONG>rmm</STRONG> is sent when <STRONG>meta</STRONG>(<EM>win</EM>,
+       <STRONG>FALSE</STRONG>) is called.
+
+

+       The <STRONG>nl</STRONG> and <STRONG>nonl</STRONG> routines control whether the underlying display  device
+       translates the return key into newline on input.
+
+
+</PRE><H3><a name="h3-nodelay">nodelay</a></H3><PRE>
+       The <STRONG>nodelay</STRONG> option causes <STRONG>getch</STRONG> to be a non-blocking call.  If no input
+       is ready, <STRONG>getch</STRONG> returns <STRONG>ERR</STRONG>.  If disabled (<EM>bf</EM> is  <STRONG>FALSE</STRONG>),  <STRONG>getch</STRONG>  waits
+       until a key is pressed.
+
+

+       When  interpreting  an  escape  sequence, <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG> sets a timer while
+       waiting for the next character.  If  <STRONG>notimeout(</STRONG><EM>win</EM>,  <STRONG>TRUE</STRONG>)  is  called,
+       then  <STRONG>wgetch</STRONG>  does  not  set a timer.  The purpose of the timeout is to
+       differentiate between sequences received from a function key and  those
+       typed by a user.
+
+
+</PRE><H3><a name="h3-raw_noraw">raw/noraw</a></H3><PRE>
+       The  <STRONG>raw</STRONG> and <STRONG>noraw</STRONG> routines place the terminal into or out of raw mode.
+       Raw mode is similar to <STRONG>cbreak</STRONG> mode, in that characters typed are  imme-
+       diately  passed  through to the user program.  The differences are that
+       in raw mode, the interrupt, quit, suspend, and flow control  characters
+       are  all  passed through uninterpreted, instead of generating a signal.
+       The behavior of the BREAK key depends on other bits in the  tty  driver
+       that are not set by <STRONG>curses</STRONG>.

+       done  [see  <STRONG>termios(3)</STRONG>].   When  <STRONG>qiflush</STRONG>  is called, the queues will be
+       flushed when these control characters are read.  You may want  to  call
+       <STRONG>noqiflush</STRONG>  in a signal handler if you want output to continue as though
+       the interrupt had not occurred, after the handler exits.

+       The <STRONG>timeout</STRONG> and <STRONG>wtimeout</STRONG> routines set blocking or non-blocking read for
+       a  given  window.   If  <EM>delay</EM> is negative, blocking read is used (i.e.,
+       waits indefinitely for input).  If <EM>delay</EM>  is  zero,  then  non-blocking
+       read is used (i.e., read returns <STRONG>ERR</STRONG> if no input is waiting).  If <EM>delay</EM>
+       is positive, then read blocks for <EM>delay</EM> milliseconds, and  returns  <STRONG>ERR</STRONG>
+       if  there  is  still  no input.  Hence, these routines provide the same
+       functionality as <STRONG>nodelay</STRONG>, plus the additional capability of being  able
+       to block for only <EM>delay</EM> milliseconds (where <EM>delay</EM> is positive).

+       The <STRONG>curses</STRONG> library does "line-breakout optimization" by looking for ty-
+       peahead periodically while updating the screen.  If input is found, and
+       it  is  coming  from  a  tty, the current update is postponed until <STRONG>re-</STRONG>
+       <STRONG><A HREF="refresh.3x.html">fresh(3x)</A></STRONG> or <STRONG>doupdate</STRONG> is called again.  This allows faster response  to
+       commands  typed in advance.  Normally, the input FILE pointer passed to
+       <STRONG>newterm</STRONG>, or <STRONG>stdin</STRONG> in the case that <STRONG>initscr</STRONG> was used, will be used to do
+       this typeahead checking.  The <STRONG>typeahead</STRONG> routine specifies that the file
+       descriptor <EM>fd</EM> is to be used to check for typeahead instead.  If  <EM>fd</EM>  is
+       -1, then no typeahead checking is done.

+       All  routines  that  return  an  integer return <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG>
+       (SVr4 specifies only "an integer value other than <STRONG>ERR</STRONG>") upon successful
+       completion,  unless  otherwise  noted in the preceding routine descrip-
+       tions.
+
+       X/Open does not define any error conditions.  In  this  implementation,
+       functions  with  a window parameter will return an error if it is null.
+       Any function will also return an error if the terminal was not initial-
+       ized.  Also,
+
+              <STRONG>halfdelay</STRONG>
+                   returns  an  error  if  its  parameter is outside the range
+                   1..255.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       These functions are described in the XSI Curses standard, Issue 4.
+
+       The ncurses library obeys the XPG4 standard and the historical practice
+       of  the  AT&amp;T  curses  implementations, in that the echo bit is cleared
+       when curses initializes the terminal state.  BSD curses  differed  from
+       this  slightly;  it left the echo bit on at initialization, but the BSD
+       <STRONG>raw</STRONG> call turned it off as a side-effect.   For  best  portability,  set
+       <STRONG>echo</STRONG>  or <STRONG>noecho</STRONG> explicitly just after initialization, even if your pro-
+       gram remains in cooked mode.
+
+       The XSI Curses standard is ambiguous on the  question  of  whether  <STRONG>raw</STRONG>
+       should  disable  the  CRLF translations controlled by <STRONG>nl</STRONG> and <STRONG>nonl</STRONG>.  BSD
+       curses did turn off these translations; AT&amp;T curses (at least  as  late
+       as  SVr1)  did not.  We chose to do so, on the theory that a programmer
+       requesting raw input wants a clean  (ideally  8-bit  clean)  connection
+       that the operating system will not alter.
+
+       When <STRONG>keypad</STRONG> is first enabled, ncurses loads the key-definitions for the
+       current terminal description.  If the terminal description includes ex-
+       tended string capabilities, e.g., from using the <STRONG>-x</STRONG> option of <STRONG>tic</STRONG>, then
+       ncurses also defines keys for the capabilities whose names  begin  with
+       "k".  The corresponding keycodes are generated and (depending on previ-
+       ous loads of terminal descriptions) may differ from one execution of  a
+       program to the next.  The generated keycodes are recognized by the <STRONG>key-</STRONG>
+       <STRONG>name</STRONG> function (which will then return a name beginning with "k"  denot-
+       ing  the terminfo capability name rather than "K", used for curses key-
+       names).  On the other hand, an application can use <STRONG>define_key</STRONG> to estab-
+       lish a specific keycode for a given string.  This makes it possible for
+       an application to check for  an  extended  capability's  presence  with
+       <STRONG>tigetstr</STRONG>, and reassign the keycode to match its own needs.
+
+       Low-level applications can use <STRONG>tigetstr</STRONG> to obtain the definition of any
+       particular string capability.  Higher-level applications which use  the
+       curses  <STRONG>wgetch</STRONG>  and  similar functions to return keycodes rely upon the
+       order in which the strings are loaded.  If more than one key definition
+       has  the  same  string  value, then <STRONG>wgetch</STRONG> can return only one keycode.
+       Most curses implementations (including ncurses) load key definitions in
+       the  order  defined  by the array of string capability names.  The last
+       key to be loaded determines the keycode which  will  be  returned.   In
+       ncurses,  you  may  also  have extended capabilities interpreted as key
+       definitions.  These are loaded after the predefined keys, and if a  ca-
+       pability's value is the same as a previously-loaded key definition, the
+       later definition is the one used.

+
+       The  <STRONG>noraw</STRONG>  and  <STRONG>nocbreak</STRONG> calls follow historical practice in that they
+       attempt to restore to normal ("cooked") mode from raw and cbreak  modes
+       respectively.   Mixing raw/noraw and cbreak/nocbreak calls leads to tty
+       driver control states that are hard to predict or understand; it is not

+       These routines insert a <STRONG>wchar_t</STRONG> character string (as many characters as
+       will fit on the line) before the character under the cursor.  All char-
+       acters to the right of the cursor are shifted right, with the possibil-
+       ity of the rightmost characters on the line being lost.  No wrapping is
+       performed.   The cursor position does not change (after moving to <EM>y</EM>, <EM>x</EM>,
+       if specified).  The four routines with <EM>n</EM> as the last argument insert  a
+       leading  substring  of at most <EM>n</EM> <STRONG>wchar_t</STRONG> characters.  If <EM>n</EM> is less than
+       1, the entire string is inserted.
+
+       If a character in <EM>wstr</EM> is a tab, newline, carriage return or backspace,
+       the  cursor  is  moved appropriately within the window.  A newline also
+       does a <STRONG>clrtoeol</STRONG> before moving.  Tabs are  considered  to  be  at  every
+       eighth column.  If a character in <EM>wstr</EM> is another control character, it
+       is drawn in the <STRONG>^</STRONG><EM>X</EM> notation.  Calling <STRONG>win_wch</STRONG> after  adding  a  control
+       character  (and moving to it, if necessary) does not return the control
+       character, but instead returns a character in the  ^-representation  of
+       the control character.
+
+
+</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
+       Note that all but wins_nwstr may be macros.
+
+       If  the  first character in the string is a nonspacing character, these
+       functions will fail.  XSI does not define what will happen  if  a  non-
+       spacing character follows a control character.

+       Upon successful completion, these functions return <STRONG>OK</STRONG>.  Otherwise, they

+
+       Functions with a "mv" prefix first  perform  a  cursor  movement  using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.

+       These routines return a string of characters in <EM>str</EM>, extracted starting
+       at  the  current  cursor  position in the named window.  Attributes are
+       stripped from the characters.  The four functions with <EM>n</EM>  as  the  last
+       argument   return  a  leading  substring  at  most  <EM>n</EM>  characters  long
+       (exclusive of the trailing NUL).

+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       All of the  functions  return  <STRONG>ERR</STRONG>  upon  failure,  or  the  number  of
+       characters actually read into the string.
+
+       X/Open Curses defines no error conditions.  In this implementation:
+
+       <STRONG>o</STRONG>   If the <EM>win</EM> parameter is null, an error is returned,
+
+       <STRONG>o</STRONG>   If the <EM>chstr</EM> parameter is null, an error is returned,
+
+       Functions  with  a  "mv"  prefix  first perform a cursor movement using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.

+       SVr4  does not document whether a length limit includes or excludes the
+       trailing NUL.
+
+       The ncurses library extends the XSI description by allowing a  negative
+       value  for  <EM>n</EM>.  In this case, the functions return the string ending at
+       the right margin.

+       The following routines give low-level access to various <STRONG>curses</STRONG> capabil-
+       ities.  These routines typically are used inside library routines.
+
+
+</PRE><H3><a name="h3-def_prog_mode_-def_shell_mode">def_prog_mode, def_shell_mode</a></H3><PRE>
+       The <STRONG>def_prog_mode</STRONG> and <STRONG>def_shell_mode</STRONG> routines save the current terminal
+       modes as the "program" (in <STRONG>curses</STRONG>) or "shell" (not in <STRONG>curses</STRONG>) state for
+       use by the <STRONG>reset_prog_mode</STRONG> and <STRONG>reset_shell_mode</STRONG> routines.  This is done
+       automatically  by <STRONG>initscr</STRONG>.  There is one such save area for each screen
+       context allocated by <STRONG>newterm</STRONG>.
+
+
+</PRE><H3><a name="h3-reset_prog_mode_-reset_shell_mode">reset_prog_mode, reset_shell_mode</a></H3><PRE>
+       The <STRONG>reset_prog_mode</STRONG> and <STRONG>reset_shell_mode</STRONG> routines restore the  terminal
+       to  "program"  (in <STRONG>curses</STRONG>) or "shell" (out of <STRONG>curses</STRONG>) state.  These are
+       done automatically by <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG> and, after an <STRONG>endwin</STRONG>, by <STRONG>doupdate</STRONG>,  so
+       they normally are not called.
+
+
+</PRE><H3><a name="h3-resetty_-savetty">resetty, savetty</a></H3><PRE>
+       The <STRONG>resetty</STRONG> and <STRONG>savetty</STRONG> routines save and restore the state of the ter-
+       minal modes.  <STRONG>savetty</STRONG> saves the current state in a buffer  and  <STRONG>resetty</STRONG>
+       restores the state to what it was at the last call to <STRONG>savetty</STRONG>.
+
+
+</PRE><H3><a name="h3-getsyx">getsyx</a></H3><PRE>
+       The  <STRONG>getsyx</STRONG>  routine  returns  the  current  coordinates of the <EM>virtual</EM>
+       <EM>screen</EM> cursor in <EM>y</EM> and <EM>x</EM>.  If <STRONG>leaveok</STRONG> is currently <STRONG>TRUE</STRONG>, then <STRONG>-1</STRONG>,<STRONG>-1</STRONG>  is
+       returned.  If lines have been removed from the top of the screen, using
+       <STRONG>ripoffline</STRONG>, <EM>y</EM> and <EM>x</EM> include these lines; therefore, <EM>y</EM> and <EM>x</EM>  should  be
+       used only as arguments for <STRONG>setsyx</STRONG>.
+
+       Few applications will use this feature, most use <STRONG>getyx</STRONG> instead.
+
+
+</PRE><H3><a name="h3-setsyx">setsyx</a></H3><PRE>
+       The  <STRONG>setsyx</STRONG> routine sets the <EM>virtual</EM> <EM>screen</EM> cursor to <EM>y</EM>, <EM>x</EM>.  If <EM>y</EM> and <EM>x</EM>
+       are both <STRONG>-1</STRONG>, then <STRONG>leaveok</STRONG> is set.  The two routines <STRONG>getsyx</STRONG>  and  <STRONG>setsyx</STRONG>
+       are  designed to be used by a library routine, which manipulates <STRONG>curses</STRONG>
+       windows but does not want to change the current position  of  the  pro-
+       gram's cursor.  The library routine would call <STRONG>getsyx</STRONG> at the beginning,
+       do its manipulation of its own windows, do a <STRONG>wnoutrefresh</STRONG> on  its  win-
+       dows, call <STRONG>setsyx</STRONG>, and then call <STRONG>doupdate</STRONG>.
+
+       Few applications will use this feature, most use <STRONG>wmove</STRONG> instead.
+
+
+</PRE><H3><a name="h3-ripoffline">ripoffline</a></H3><PRE>
+       The  <STRONG>ripoffline</STRONG>  routine  provides  access  to  the  same facility that
+       <STRONG>slk_init</STRONG> [see <STRONG><A HREF="curs_slk.3x.html">curs_slk(3x)</A></STRONG>] uses to reduce  the  size  of  the  screen.
+       <STRONG>ripoffline</STRONG>  must be called before <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG> is called, to pre-
+       pare these initial actions:
+
+       <STRONG>o</STRONG>   If <EM>line</EM> is positive, a line is removed from the top of <STRONG>stdscr</STRONG>.
+
+       <STRONG>o</STRONG>   if <EM>line</EM> is negative, a line is removed from the bottom.
+
+       When the resulting initialization is done inside <STRONG>initscr</STRONG>,  the  routine
+       <STRONG>init</STRONG> (supplied by the user) is called with two arguments:
+
+       <STRONG>o</STRONG>   a window pointer to the one-line window that has been allocated and
+
+       <STRONG>o</STRONG>   an integer with the number of columns in the window.
+
+       Inside  this  initialization  routine,  the integer variables <STRONG>LINES</STRONG> and
+       <STRONG>COLS</STRONG> (defined in <STRONG>&lt;curses.h&gt;</STRONG>) are not guaranteed to be accurate and <STRONG>wre-</STRONG>
+       <STRONG>fresh</STRONG> or <STRONG>doupdate</STRONG> must not be called.  It is allowable to call <STRONG>wnoutre-</STRONG>
+       <STRONG>fresh</STRONG> during the initialization routine.
+
+       <STRONG>ripoffline</STRONG> can be called up to five times  before  calling  <STRONG>initscr</STRONG>  or
+       <STRONG>newterm</STRONG>.
+
+
+</PRE><H3><a name="h3-curs_set">curs_set</a></H3><PRE>
+       The  <STRONG>curs_set</STRONG>  routine  sets  the cursor state to invisible, normal, or
+       very visible for <STRONG>visibility</STRONG> equal to <STRONG>0</STRONG>, <STRONG>1</STRONG>, or <STRONG>2</STRONG> respectively.   If  the
+       terminal  supports  the <EM>visibility</EM> requested, the previous <EM>cursor</EM> state
+       is returned; otherwise, <STRONG>ERR</STRONG> is returned.
+
+
+</PRE><H3><a name="h3-napms">napms</a></H3><PRE>
+       The <STRONG>napms</STRONG> routine is used to sleep for <EM>ms</EM> milliseconds.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       Except for <STRONG>curs_set</STRONG>, these routines always return <STRONG>OK</STRONG>.
+
+       <STRONG>curs_set</STRONG> returns the previous cursor state, or  <STRONG>ERR</STRONG>  if  the  requested
+       <EM>visibility</EM> is not supported.
+
+       X/Open defines no error conditions.  In this implementation
+
+       <STRONG>def_prog_mode</STRONG>, <STRONG>def_shell_mode</STRONG>, <STRONG>reset_prog_mode</STRONG>, <STRONG>reset_shell_mode</STRONG>
+            return an error if the terminal was not initialized, or if the I/O
+            call to obtain the terminal settings fails.
+
+       <STRONG>ripoffline</STRONG>
+            returns an error if the maximum number of ripped-off lines exceeds
+            the maximum (NRIPS = 5).
+
+
+</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
+       Note that <STRONG>getsyx</STRONG> is a macro, so <STRONG>&amp;</STRONG> is not necessary before the variables
+       <EM>y</EM> and <EM>x</EM>.
+
+       Older SVr4 man pages warn that the return value of  <STRONG>curs_set</STRONG>  "is  cur-
+       rently  incorrect".   This  implementation gets it right, but it may be
+       unwise to count on the correctness of the return value anywhere else.
+
+       Both ncurses and SVr4 will call <STRONG>curs_set</STRONG> in <STRONG>endwin</STRONG> if <STRONG>curs_set</STRONG> has been
+       called  to make the cursor other than normal, i.e., either invisible or
+       very visible.  There is no way for ncurses  to  determine  the  initial
+       cursor state to restore that.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       The <EM>virtual</EM> <EM>screen</EM> functions <STRONG>setsyx</STRONG> and <STRONG>getsyx</STRONG> are not described in the
+       XSI Curses standard, Issue 4.  All other functions are as described  in
+       XSI Curses.
+
+       The  SVr4  documentation  describes  <STRONG>setsyx</STRONG> and <STRONG>getsyx</STRONG> as having return
+       type int.  This is misleading, as they are macros  with  no  documented
+       semantics for the return value.

+       These  legacy  functions  are  simpler  to  use  than the X/Open Curses
+       functions:
+
+       <STRONG>o</STRONG>   The <STRONG>getattrs</STRONG> function returns the same attribute data as <STRONG>wattr_get</STRONG>.
+
+           However, <STRONG>getattrs</STRONG> returns an integer  (actually  a  <STRONG>chtype</STRONG>),  while
+           <STRONG>wattr_get</STRONG>  returns  the current color pair in a separate parameter.
+           In the wide-character library configuration, color  pairs  may  not
+           fit into a <STRONG>chtype</STRONG>, so <STRONG>wattr_get</STRONG> is the only way to obtain the color
+           information.
+
+           Because <STRONG>getattrs</STRONG> returns the attributes in a single  parameter,  it
+           would  not  be possible for an application to distinguish that from
+           <STRONG>ERR</STRONG> (a <EM>-1</EM>).  If the window  parameter  is  null,  <STRONG>getattrs</STRONG>  returns
+           <STRONG>A_NORMAL</STRONG> (zero).
+
+       <STRONG>o</STRONG>   The <STRONG>getbegy</STRONG> and <STRONG>getbegx</STRONG> functions return the same data as <STRONG>getbegyx</STRONG>.
+
+       <STRONG>o</STRONG>   The <STRONG>getcury</STRONG> and <STRONG>getcurx</STRONG> functions return the same data as <STRONG>getyx</STRONG>.
+
+       <STRONG>o</STRONG>   The <STRONG>getmaxy</STRONG> and <STRONG>getmaxx</STRONG> functions return the same data as <STRONG>getmaxyx</STRONG>.
+
+       <STRONG>o</STRONG>   The <STRONG>getpary</STRONG> and <STRONG>getparx</STRONG> functions return the same data as <STRONG>getparyx</STRONG>.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>

+       All of these interfaces are provided  as  macros  and  functions.   The

+       These  functions  are  used to simplify analysis of memory leaks in the
+       ncurses library.
+
+       Any implementation of curses must not free the memory associated with a
+       screen, since (even after calling <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG>), it must be available for
+       use in the next call to <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG>.  There are also chunks  of  memory
+       held for performance reasons.  That makes it hard to analyze curses ap-
+       plications for memory leaks.  When using the specially  configured  de-
+       bugging version of the ncurses library, applications can call functions
+       which free those chunks of memory, simplifying the process  of  memory-
+       leak checking.
+
+       Some  of  the functions are named with a "_nc_" prefix because they are
+       not intended for use in the non-debugging library:
+
+       <STRONG>_nc_freeall</STRONG>
+            This frees (almost) all of the memory allocated by ncurses.
+
+       <STRONG>_nc_free_and_exit</STRONG>
+            This frees the memory allocated by ncurses (like <STRONG>_nc_freeall</STRONG>), and
+            exits the program.  It is preferred over <STRONG>_nc_freeall</STRONG> since some of
+            that memory may be required to keep the application running.  Sim-
+            ply exiting (with the given exit-code) is safer.
+
+       <STRONG>_nc_free_tinfo</STRONG>
+            Use  this  function  if only the low-level terminfo functions (and
+            corresponding library) are used.  Like <STRONG>_nc_free_and_exit</STRONG>, it exits
+            the program after freeing memory.
+
+       The  functions  prefixed "_nc" are normally not available; they must be
+       configured into the library at build time using the <STRONG>--disable-leaks</STRONG> op-
+       tion.   That compiles-in code that frees memory that normally would not
+       be freed.
+
+       The <STRONG>exit_curses</STRONG> and <STRONG>exit_terminfo</STRONG> functions call <STRONG>_nc_free_and_exit</STRONG>  and
+       <STRONG>_nc_free_tinfo</STRONG>  if  the  library  is  configured to support memory-leak
+       checking.  If the library is  not  configured  to  support  memory-leak
+       checking, they simply call <STRONG>exit</STRONG>.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       These functions do not return a value.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       These functions are not part of X/Open Curses; nor do other implementa-
+       tions of curses provide a similar feature.
+
+       In any implementation of X/Open Curses, an application can free part of
+       the memory allocated by curses:
+
+       <STRONG>o</STRONG>   The  portable  part  of  <STRONG>exit_curses</STRONG>  can be freed using <STRONG>delscreen</STRONG>,
+           passing the <STRONG>SCREEN*</STRONG> pointer returned by <STRONG>newterm</STRONG>.
+
+           In some implementations, there is a global variable <STRONG>sp</STRONG> which  could
+           be used, e.g., if the screen were only initialized using <STRONG>initscr</STRONG>.
+
+       <STRONG>o</STRONG>   The portable part of <STRONG>exit_terminfo</STRONG> can be freed using <STRONG>del_curterm</STRONG>.
+
+           In this case, there is a global variable <STRONG>cur_term</STRONG> which can be used
+           as parameter.

+       To make mouse events visible, use the <STRONG>mousemask</STRONG>  function.   This  sets
+       the  mouse  events to be reported.  By default, no mouse events are re-
+       ported.

+       The <STRONG>wmouse_trafo</STRONG> function transforms a given pair of  coordinates  from
+       stdscr-relative coordinates to coordinates relative to the given window
+       or vice versa.  The resulting stdscr-relative coordinates are  not  al-
+       ways  identical  to window-relative coordinates due to the mechanism to
+       reserve lines on top or bottom of the screen for  other  purposes  (see
+       the <STRONG>ripoffline</STRONG> and <STRONG><A HREF="curs_slk.3x.html">slk_init(3x)</A></STRONG> calls, for example).

+           converted  to  window-relative coordinates and returned through the

+       These calls were designed for <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>, and are not  found  in  SVr4
+       curses, 4.4BSD curses, or any other previous version of curses.
+
+       SVr4  curses had support for the mouse in a variant of <STRONG>xterm(1)</STRONG>.  It is
+       mentioned in a few places, but with no supporting documentation:
+
+       <STRONG>o</STRONG>   the "libcurses" manual page lists functions for this feature  which
+           are prototyped in <STRONG>curses.h</STRONG>:
+
+               extern int mouse_set(long int);
+               extern int mouse_on(long int);
+               extern int mouse_off(long int);
+               extern int request_mouse_pos(void);
+               extern int map_button(unsigned long);
+               extern void wmouse_position(WINDOW *, int *, int *);
+               extern unsigned long getmouse(void), getbmap(void);
+
+       <STRONG>o</STRONG>   the "terminfo" manual page lists capabilities for the feature
+
+               buttons           btns    BT       Number of buttons on the mouse
+               get_mouse         getm    Gm       Curses should get button events
+               key_mouse         kmous   Km       0631, Mouse event has occurred
+               mouse_info        minfo   Mi       Mouse status information
+               req_mouse_pos     reqmp   RQ       Request mouse position report
+
+       <STRONG>o</STRONG>   the  interface  made assumptions (as does ncurses) about the escape
+           sequences sent to and received from the terminal.
+
+           For instance the SVr4 curses library used the <STRONG>get_mouse</STRONG>  capability
+           to  tell  the  terminal  which  mouse button events it should send,
+           passing the mouse-button bit-mask to the terminal.  Also, it  could
+           ask  the terminal where the mouse was using the <STRONG>req_mouse_pos</STRONG> capa-
+           bility.
+
+           Those features required a terminal which had been modified to  work
+           with curses.  They were not part of the X Consortium's xterm.
+
+       When  developing the xterm mouse support for ncurses in September 1995,
+       Eric Raymond was uninterested in using the same interface  due  to  its
+       lack of documentation.  Later, in 1998, Mark Hesseling provided support
+       in PDCurses 2.3 using the SVr4 interface.  PDCurses, however, does  not
+       use  video  terminals, making it unnecessary to be concerned about com-
+       patibility with the escape sequences.
+
+       The feature macro <STRONG>NCURSES_MOUSE_VERSION</STRONG> is provided so the preprocessor
+       can  be used to test whether these features are present.  If the inter-
+       face is changed, the value of <STRONG>NCURSES_MOUSE_VERSION</STRONG> will be  increment-
+       ed.   These values for <STRONG>NCURSES_MOUSE_VERSION</STRONG> may be specified when con-
+       figuring ncurses:
+
+          1  has definitions for reserved events.  The mask uses 28 bits.
+
+          2  adds definitions for button 5, removes the  definitions  for  re-
+             served events.  The mask uses 29 bits.
+
+       The order of the <STRONG>MEVENT</STRONG> structure members is not guaranteed.  Addition-
+       al fields may be added to the structure in the future.
+
+       Under <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>, these calls are  implemented  using  either  xterm's
+       built-in mouse-tracking API or platform-specific drivers including
+
+          <STRONG>o</STRONG>   Alessandro Rubini's gpm server
+
+          <STRONG>o</STRONG>   FreeBSD sysmouse
+
+          <STRONG>o</STRONG>   OS/2 EMX
+
+       If you are using an unsupported configuration, mouse events will not be
+       visible to <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG> (and the <STRONG>mousemask</STRONG> function will  always  return
+       <STRONG>0</STRONG>).
+
+       If  the  terminfo entry contains a <STRONG>XM</STRONG> string, this is used in the xterm
+       mouse driver to control the way the terminal is initialized  for  mouse
+       operation.   The  default,  if  <STRONG>XM</STRONG> is not found, corresponds to private
+       mode 1000 of xterm:
+
+          \E[?1000%?%p1%{1}%=%th%el%;
+
+       The mouse driver also recognizes a newer xterm private mode 1006, e.g.,
+
+          \E[?1006;1000%?%p1%{1}%=%th%el%;
+
+       The <EM>z</EM> member in the event structure is not presently used.  It  is  in-
+       tended  for use with touch screens (which may be pressure-sensitive) or
+       with 3D-mice/trackballs/power gloves.
+
+       The <STRONG>ALL_MOUSE_EVENTS</STRONG>  class  does  not  include  <STRONG>REPORT_MOUSE_POSITION</STRONG>.
+       They  are  distinct.   For example, in xterm, wheel/scrolling mice send
+       position reports as a sequence of presses of buttons  4  or  5  without
+       matching button-releases.
+
+
+</PRE><H2><a name="h2-BUGS">BUGS</a></H2><PRE>
+       Mouse  events  under  xterm  will  not in fact be ignored during cooked
+       mode, if they have been enabled by <STRONG>mousemask</STRONG>.  Instead, the xterm mouse
+       report sequence will appear in the string read.
+
+       Mouse  events  under  xterm  will not be detected correctly in a window
+       with its keypad bit off, since they are interpreted  as  a  variety  of
+       function  key.   Your  terminfo  description  should  have <STRONG>kmous</STRONG> set to
+       "\E[M" (the beginning of the response from  xterm  for  mouse  clicks).
+       Other  values  for  <STRONG>kmous</STRONG> are permitted, but under the same assumption,
+       i.e., it is the beginning of the response.
+
+       Because there are no standard terminal responses that  would  serve  to
+       identify  terminals which support the xterm mouse protocol, <STRONG>ncurses</STRONG> as-
+       sumes that if <STRONG>kmous</STRONG> is defined in the terminal description, or  if  the
+       terminal  description's  primary  name  or  aliases  contain the string
+       "xterm", then the terminal may send mouse events.  The <STRONG>kmous</STRONG> capability
+       is  checked first, allowing the use of newer xterm mouse protocols such
+       as xterm's private mode 1006.

+       If <STRONG>clearok</STRONG> is called with <STRONG>TRUE</STRONG> as argument, the next call  to  <STRONG>wrefresh</STRONG>
+       with this window will clear the screen completely and redraw the entire
+       screen from scratch.  This is useful when the contents  of  the  screen
+       are  uncertain, or in some cases for a more pleasing visual effect.  If
+       the <EM>win</EM> argument to <STRONG>clearok</STRONG> is the global  variable  <STRONG>curscr</STRONG>,  the  next

+       disabled by default because insert/delete line tends to be visually an-
+       noying when used in applications where it is not really needed.  If in-

+       Normally, the hardware cursor is left at the  location  of  the  window
+       cursor  being  refreshed.   The  <STRONG>leaveok</STRONG> option allows the cursor to be
+       left wherever the update happens to leave it.  It is useful for  appli-
+       cations  where  the  cursor  is not used, since it reduces the need for
+       cursor motions.

+       The <STRONG>scrollok</STRONG> option controls what happens when the cursor of  a  window
+       is  moved  off  the edge of the window or scrolling region, either as a
+       result of a newline action on the bottom line, or typing the last char-
+       acter of the last line.  If disabled, (<EM>bf</EM> is <STRONG>FALSE</STRONG>), the cursor is left
+       on the bottom line.  If enabled, (<EM>bf</EM> is <STRONG>TRUE</STRONG>), the window  is  scrolled
+       up one line (Note that to get the physical scrolling effect on the ter-
+       minal, it is also necessary to call <STRONG>idlok</STRONG>).
+
+
+</PRE><H3><a name="h3-setscrreg_wsetscrreg">setscrreg/wsetscrreg</a></H3><PRE>
+       The <STRONG>setscrreg</STRONG> and <STRONG>wsetscrreg</STRONG> routines allow the application  programmer
+       to set a software scrolling region in a window.  The <EM>top</EM> and <EM>bot</EM> param-
+       eters are the line  numbers  of  the  top  and  bottom  margin  of  the
+       scrolling region.  (Line 0 is the top line of the window.)  If this op-
+       tion and <STRONG>scrollok</STRONG> are enabled, an attempt to move off the bottom margin
+       line causes all lines in the scrolling region to scroll one line in the
+       direction of the first line.  Only the text of the window is  scrolled.
+       (Note  that this has nothing to do with the use of a physical scrolling
+       region capability in the terminal, like that in the VT100.  If <STRONG>idlok</STRONG> is
+       enabled and the terminal has either a scrolling region or insert/delete
+       line capability, they will probably be used by the output routines.)

+       The functions <STRONG>setscrreg</STRONG> and <STRONG>wsetscrreg</STRONG> return <STRONG>OK</STRONG> upon success  and  <STRONG>ERR</STRONG>
+       upon  failure.  All other routines that return an integer always return
+       <STRONG>OK</STRONG>.
+
+       X/Open Curses does not define any error conditions.
+

+

+           the window pointer is null
+
+       <STRONG>o</STRONG>   <STRONG>wsetscrreg</STRONG>  returns  an error if the scrolling region limits extend
+           outside the window.
+
+       X/Open does not define any error conditions.  This  implementation  re-
+       turns an error if the window pointer is null.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       These functions are described in the XSI Curses standard, Issue 4.
+
+       From the outset, ncurses used <STRONG>nl</STRONG>/<STRONG>nonl</STRONG> to control the conversion of new-
+       lines to carriage return/line-feed on output as  well  as  input.   XSI
+       Curses  documents only the use of these functions for input.  This dif-
+       ference arose from converting the  <EM>pcurses</EM>  source  (which  used  <STRONG>ioctl</STRONG>
+       calls  with  the <STRONG>sgttyb</STRONG> structure) to termios (i.e., the POSIX terminal
+       interface).  In the former, both input and output were controlled via a
+       single  option  <STRONG>CRMOD</STRONG>,  while the latter separates these features.  Be-
+       cause that conversion interferes with output optimization, <STRONG>nl</STRONG>/<STRONG>nonl</STRONG> were
+       amended after ncurses 6.2 to eliminate their effect on output.
+
+       Some  historic  curses implementations had, as an undocumented feature,
+       the ability to do the equivalent of <STRONG>clearok(...,</STRONG> <STRONG>1)</STRONG>  by  saying  <STRONG>touch-</STRONG>
+       <STRONG>win(stdscr)</STRONG> or <STRONG>clear(stdscr)</STRONG>.  This will not work under ncurses.
+
+       Earlier  System  V  curses implementations specified that with <STRONG>scrollok</STRONG>
+       enabled, any window modification triggering  a  scroll  also  forced  a
+       physical refresh.  XSI Curses does not require this, and <STRONG>ncurses</STRONG> avoids
+       doing it to perform better  vertical-motion  optimization  at  <STRONG>wrefresh</STRONG>
+       time.
+
+       The XSI Curses standard does not mention that the cursor should be made
+       invisible as a side-effect of <STRONG>leaveok</STRONG>.  SVr4 curses documentation  does
+       this,  but  the code does not.  Use <STRONG>curs_set</STRONG> to make the cursor invisi-
+       ble.

+       The <STRONG>newpad</STRONG> routine creates and returns a pointer  to  a  new  pad  data
+       structure  with  the given number of lines, <EM>nlines</EM>, and columns, <EM>ncols</EM>.
+       A pad is like a window, except that it is not restricted by the  screen
+       size,  and  is not necessarily associated with a particular part of the
+       screen.  Pads can be used when a large window is  needed,  and  only  a
+       part  of  the  window will be on the screen at one time.  Automatic re-
+       freshes of pads (e.g., from scrolling or echoing of input) do  not  oc-
+       cur.
+
+       It  is  not  legal to call <STRONG>wrefresh</STRONG> with a <EM>pad</EM> as an argument; the rou-
+       tines <STRONG>prefresh</STRONG> or <STRONG>pnoutrefresh</STRONG> should be  called  instead.   Note  that
+       these routines require additional parameters to specify the part of the
+       pad to be displayed and the location on the screen to be used  for  the
+       display.
+
+
+</PRE><H3><a name="h3-subpad">subpad</a></H3><PRE>
+       The  <STRONG>subpad</STRONG> routine creates and returns a pointer to a subwindow within
+       a pad with the given number of lines, <EM>nlines</EM>, and columns, <EM>ncols</EM>.   Un-
+       like  <STRONG>subwin</STRONG>,  which uses screen coordinates, the window is at position
+       (<EM>begin</EM>_<EM>x</EM><STRONG>,</STRONG> <EM>begin</EM>_<EM>y</EM>) on the pad.  The window is made in the middle of the
+       window  <EM>orig</EM>,  so  that changes made to one window affect both windows.
+       During the use of this routine, it will  often  be  necessary  to  call
+       <STRONG>touchwin</STRONG> or <STRONG>touchline</STRONG> on <EM>orig</EM> before calling <STRONG>prefresh</STRONG>.
+
+
+</PRE><H3><a name="h3-prefresh_-pnoutrefresh">prefresh, pnoutrefresh</a></H3><PRE>
+       The  <STRONG>prefresh</STRONG>  and  <STRONG>pnoutrefresh</STRONG> routines are analogous to <STRONG>wrefresh</STRONG> and
+       <STRONG>wnoutrefresh</STRONG> except that they relate to pads instead of  windows.   The
+       additional  parameters  are needed to indicate what part of the pad and
+       screen are involved.
+
+       <STRONG>o</STRONG>   The <EM>pminrow</EM> and <EM>pmincol</EM> parameters specify the upper left-hand cor-
+           ner of the rectangle to be displayed in the pad.
+
+       <STRONG>o</STRONG>   The  <EM>sminrow</EM>,  <EM>smincol</EM>, <EM>smaxrow</EM>, and <EM>smaxcol</EM> parameters specify the
+           edges of the rectangle to be displayed on the screen.
+
+       The lower right-hand corner of the rectangle to be displayed in the pad

+       BSD curses has no <EM>pad</EM> feature.
+
+       SVr2 curses (1986) provided the <STRONG>newpad</STRONG> and related functions, document-
+       ing  them  in  a single line each.  SVr3 (1987) provided more extensive
+       documentation.
+
+       The documentation does not explain the term <EM>pad</EM>.  However,  the  Apollo
+       <EM>Aegis</EM> workstation operating system supported a graphical <EM>pad</EM> feature:
+
+       <STRONG>o</STRONG>   These  graphical pads could be much larger than the computer's dis-
+           play.
+
+       <STRONG>o</STRONG>   The read-only output from a command could be scrolled back  to  in-
+           spect, and select text from the pad.
+
+       The two uses may be related.
+
+       The  XSI  Curses  standard,  Issue 4 describes these functions, without
+       significant change from the SVr3 documentation.  It describes no  error
+       conditions.   The  behavior of <STRONG>subpad</STRONG> if the parent window is not a pad
+       is undocumented, and is not checked by the vendor Unix implementations:
+
+       <STRONG>o</STRONG>   SVr4 curses sets a flag in the <STRONG>WINDOW</STRONG>  structure  in  <STRONG>newpad</STRONG>  which
+           tells if the window is a <EM>pad</EM>.
+
+           However,  it  uses this information only in <STRONG>waddch</STRONG> (to decide if it
+           should call <STRONG>wrefresh</STRONG>) and <STRONG>wscrl</STRONG> (to avoid  scrolling  a  pad),  and
+           does  not  check  in  <STRONG>wrefresh</STRONG>  to ensure that the pad is refreshed
+           properly.
+
+       <STRONG>o</STRONG>   Solaris X/Open Curses checks if a window is a pad in  <STRONG>wnoutrefresh</STRONG>,
+           returning <STRONG>ERR</STRONG> in that case.
+
+           However,  it only sets the flag for subwindows if the parent window
+           is a pad.  Its <STRONG>newpad</STRONG> function does not set this information.  Con-
+           sequently, the check will never fail.
+
+           It  makes no comparable check in <STRONG>pnoutrefresh</STRONG>, though interestingly
+           enough, a comment in the source code states  that  the  lack  of  a
+           check was an MKS extension.
+
+       <STRONG>o</STRONG>   NetBSD  7 curses sets a flag in the <STRONG>WINDOW</STRONG> structure for <STRONG>newpad</STRONG> and
+           <STRONG>subpad</STRONG>, using this to help with the  distinction  between  <STRONG>wnoutre-</STRONG>
+           <STRONG>fresh</STRONG> and <STRONG>pnoutrefresh</STRONG>.
+
+           It  does  not  check for the case where a subwindow is created in a
+           pad using <STRONG>subwin</STRONG> or <STRONG>derwin</STRONG>.
+
+           The <STRONG>dupwin</STRONG> function returns a regular  window  when  duplicating  a
+           pad.   Likewise,  <STRONG>getwin</STRONG> always returns a window, even if the saved
+           data was from a pad.
+
+       This implementation
+
+       <STRONG>o</STRONG>   sets a flag in the <STRONG>WINDOW</STRONG> structure for <STRONG>newpad</STRONG> and <STRONG>subpad</STRONG>,
+
+       <STRONG>o</STRONG>   allows a <STRONG>subwin</STRONG> or <STRONG>derwin</STRONG> call to succeed having a  pad  parent  by
+           forcing the subwindow to be a pad,
+
+       <STRONG>o</STRONG>   checks  in  both  <STRONG>wnoutrefresh</STRONG> and <STRONG>pnoutrefresh</STRONG> to ensure that pads
+           and windows are handled distinctly, and
+
+       <STRONG>o</STRONG>   ensures that <STRONG>dupwin</STRONG> and <STRONG>getwin</STRONG> treat pads  versus  windows  consis-
+           tently.

+       The <STRONG>printw</STRONG>, <STRONG>wprintw</STRONG>, <STRONG>mvprintw</STRONG> and <STRONG>mvwprintw</STRONG> routines are  analogous  to
+       <STRONG>printf</STRONG>  [see <STRONG>printf(3)</STRONG>].  In effect, the string that would be output by
+       <STRONG>printf</STRONG> is output instead as though <STRONG>waddstr</STRONG> were used on the given  win-
+       dow.
+
+       The  <STRONG>vwprintw</STRONG>  and  <STRONG>vw_printw</STRONG>  routines  are  analogous to <STRONG>vprintf</STRONG> [see
+       <STRONG>printf(3)</STRONG>] and perform a <STRONG>wprintw</STRONG> using a variable argument  list.   The
+       third  argument  is a <STRONG>va_list</STRONG>, a pointer to a list of arguments, as de-
+       fined in <STRONG>&lt;stdarg.h&gt;</STRONG>.

+       only  specifies "an integer value other than <STRONG>ERR</STRONG>") upon successful com-

+
+       X/Open defines no error conditions.  In this implementation,  an  error
+       may be returned if it cannot allocate enough memory for the buffer used
+       to format the results.  It will return an error if the  window  pointer
+       is null.
+
+       Functions  with  a  "mv"  prefix  first perform a cursor movement using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.
+
+
+</PRE><H2><a name="h2-HISTORY">HISTORY</a></H2><PRE>
+       While <STRONG>printw</STRONG> was implemented in 4BSD, it was unused until 4.2BSD (which
+       used it in games).  That early version of curses was before the ANSI  C
+       standard.   It  did not use &lt;varargs.h&gt;, though that was available.  In
+       1991 (a couple of years after SVr4 was generally available,  and  after
+       the  C  standard  was published), other developers updated the library,
+       using &lt;stdarg.h&gt; internally in 4.4BSD curses.  Even with this  improve-
+       ment, BSD curses did not use function prototypes (or even declare func-
+       tions) in the &lt;curses.h&gt; header until 1992.
+
+       SVr2 documented <STRONG>printw</STRONG>, <STRONG>wprintw</STRONG>  tersely  as  "printf  on  <EM>stdscr</EM>"  and
+       tersely as "printf on <EM>win</EM>", respectively.
+
+       SVr3  added  <STRONG>mvprintw</STRONG>,  and <STRONG>mvwprintw</STRONG>, with a three-line summary saying
+       that they were analogous to <STRONG>printf(3)</STRONG>, explaining that the string which
+       would be output from <STRONG>printf(3)</STRONG> would instead be output using <STRONG>waddstr</STRONG> on
+       the given window.  SVr3 also added <STRONG>vwprintw</STRONG>, saying that the third  pa-
+       rameter  is a <STRONG>va_list</STRONG>, defined in &lt;varargs.h&gt;, and referring the reader
+       to the manual pages for <EM>varargs</EM> and <STRONG>vprintf</STRONG> for detailed descriptions.
+
+       SVr4 added  no  new  variations  of  <STRONG>printw</STRONG>,  but  provided  for  using
+       &lt;varargs.h&gt; or &lt;stdarg.h&gt; to define the <STRONG>va_list</STRONG> type.
+
+       X/Open  Curses  added  <STRONG>vw_printw</STRONG>  to replace <STRONG>vwprintw</STRONG>, stating that its
+       <STRONG>va_list</STRONG> definition requires &lt;stdarg.h&gt;.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       In this implementation, <STRONG>vw_printw</STRONG> and <STRONG>vwprintw</STRONG> are equivalent, to  sup-
+       port legacy applications.  However, the latter (<STRONG>vwprintw</STRONG>) is obsolete:
+
+       <STRONG>o</STRONG>   The  XSI  Curses  standard, Issue 4 described these functions.  The
+           function <STRONG>vwprintw</STRONG> is marked TO BE WITHDRAWN, and is to be  replaced
+           by a function <STRONG>vw_printw</STRONG> using the <STRONG>&lt;stdarg.h&gt;</STRONG> interface.
+
+       <STRONG>o</STRONG>   The  Single Unix Specification, Version 2 states that <STRONG>vw_printw</STRONG>  is
+           preferred  to  <STRONG>vwprintw</STRONG>  since  the   latter   requires   including
+           <STRONG>&lt;varargs.h&gt;</STRONG>,  which  cannot be used in the same file as <STRONG>&lt;stdarg.h&gt;</STRONG>.
+           This implementation uses <STRONG>&lt;stdarg.h&gt;</STRONG> for both, because  that  header
+           is included in <STRONG>&lt;curses.h</STRONG>&gt;.
+
+       <STRONG>o</STRONG>   X/Open  Curses, Issue 5 (December 2007) marked <STRONG>vwprintw</STRONG> (along with
+           <STRONG>vwscanw</STRONG> and the termcap interface) as withdrawn.

+       The <STRONG>refresh</STRONG> and <STRONG>wrefresh</STRONG> routines (or <STRONG>wnoutrefresh</STRONG> and  <STRONG>doupdate</STRONG>)  must
+       be called to get actual output to the terminal, as other routines mere-
+       ly manipulate data structures.  The routine <STRONG>wrefresh</STRONG> copies  the  named
+       window  to  the  <EM>physical</EM>  <EM>screen</EM>,  taking into account what is already
+       there to do optimizations.  The <STRONG>refresh</STRONG> routine is the same, using <STRONG>std-</STRONG>
+       <STRONG>scr</STRONG> as the default window.  Unless <STRONG>leaveok</STRONG> has been enabled, the physi-
+       cal cursor of the terminal is left at the location of  the  cursor  for
+       that window.
+
+
+</PRE><H3><a name="h3-wnoutrefresh_doupdate">wnoutrefresh/doupdate</a></H3><PRE>
+       The <STRONG>wnoutrefresh</STRONG> and <STRONG>doupdate</STRONG> routines allow multiple updates with more
+       efficiency than <STRONG>wrefresh</STRONG> alone.  In addition to all the  window  struc-
+       tures,  <STRONG>curses</STRONG>  keeps  two  data  structures  representing the terminal
+       screen:
+
+       <STRONG>o</STRONG>   a <EM>physical</EM> <EM>screen</EM>, describing what is actually on the screen, and
+
+       <STRONG>o</STRONG>   a <EM>virtual</EM> <EM>screen</EM>, describing what the programmer wants to  have  on
+           the screen.
+
+       The routine <STRONG>wrefresh</STRONG> works by
+
+       <STRONG>o</STRONG>   first  calling  <STRONG>wnoutrefresh</STRONG>,  which copies the named window to the
+           <EM>virtual</EM> <EM>screen</EM>, and
+
+       <STRONG>o</STRONG>   then calling <STRONG>doupdate</STRONG>, which compares the  <EM>virtual</EM>  <EM>screen</EM>  to  the
+           <EM>physical</EM> <EM>screen</EM> and does the actual update.
+
+       If the programmer wishes to output several windows at once, a series of
+       calls to <STRONG>wrefresh</STRONG> results in  alternating  calls  to  <STRONG>wnoutrefresh</STRONG>  and
+       <STRONG>doupdate</STRONG>,  causing  several  bursts  of output to the screen.  By first
+       calling <STRONG>wnoutrefresh</STRONG> for each window, it is then possible to call <STRONG>doup-</STRONG>
+       <STRONG>date</STRONG>  once,  resulting  in  only  one burst of output, with fewer total
+       characters transmitted and less CPU time used.
+
+       If the <EM>win</EM> argument to <STRONG>wrefresh</STRONG> is the <EM>physical</EM> <EM>screen</EM> (i.e., the glob-
+       al  variable  <STRONG>curscr</STRONG>),  the screen is immediately cleared and repainted
+       from scratch.
+
+       The phrase "copies the named window to the virtual screen" above is am-
+       biguous.   What actually happens is that all <EM>touched</EM> (changed) lines in
+       the window are copied to the virtual  screen.   This  affects  programs
+       that use overlapping windows; it means that if two windows overlap, you
+       can refresh them in either order and the overlap region will  be  modi-
+       fied  only  when  it  is  explicitly  changed.  (But see the section on
+       <STRONG>PORTABILITY</STRONG> below for a warning about exploiting this behavior.)
+
+
+</PRE><H3><a name="h3-wredrawln_redrawwin">wredrawln/redrawwin</a></H3><PRE>
+       The <STRONG>wredrawln</STRONG> routine indicates to <STRONG>curses</STRONG> that some  screen  lines  are
+       corrupted  and  should  be  thrown away before anything is written over
+       them.  It touches the indicated lines (marking them changed).  The rou-
+       tine <STRONG>redrawwin</STRONG> touches the entire window.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       Routines  that  return an integer return <STRONG>ERR</STRONG> upon failure, and <STRONG>OK</STRONG> (SVr4
+       only specifies "an integer value other than <STRONG>ERR</STRONG>") upon successful  com-
+       pletion.
+
+       X/Open does not define any error conditions.  In this implementation
+
+          <STRONG>wnoutrefresh</STRONG>
+               returns  an error if the window pointer is null, or if the win-
+               dow is really a pad.
+
+          <STRONG>wredrawln</STRONG>
+               returns an error if the associated call to <STRONG>touchln</STRONG>  returns  an
+               error.
+

+       The XSI Curses standard, Issue 4 describes these functions.
+
+       Whether  <STRONG>wnoutrefresh</STRONG>  copies to the virtual screen the entire contents
+       of a window or just its changed portions has never been well-documented
+       in  historic  curses  versions (including SVr4).  It might be unwise to
+       rely on either behavior in programs that might have to be  linked  with
+       other curses implementations.  Instead, you can do an explicit <STRONG>touchwin</STRONG>
+       before the <STRONG>wnoutrefresh</STRONG> call to guarantee an entire-contents copy  any-
+       where.

+       The <STRONG>scanw</STRONG>, <STRONG>wscanw</STRONG> and <STRONG>mvscanw</STRONG> routines  are  analogous  to  <STRONG>scanf</STRONG>  [see
+       <STRONG>scanf(3)</STRONG>].   The  effect  of  these  routines is as though <STRONG>wgetstr</STRONG> were
+       called on the  window,  and  the  resulting  line  used  as  input  for
+       <STRONG>sscanf(3)</STRONG>.   Fields which do not map to a variable in the <EM>fmt</EM> field are
+       lost.
+
+       The <STRONG>vwscanw</STRONG> and <STRONG>vw_scanw</STRONG> routines are  analogous  to  <STRONG>vscanf(3)</STRONG>.   They
+       perform a <STRONG>wscanw</STRONG> using a variable argument list.  The third argument is
+       a <STRONG>va_list</STRONG>, a pointer to a list of arguments, as defined in <STRONG>&lt;stdarg.h&gt;</STRONG>.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       <STRONG>vwscanw</STRONG> returns <STRONG>ERR</STRONG> on failure and an integer equal to  the  number  of
+       fields scanned on success.
+
+       Applications  may  use the return value from the <STRONG>scanw</STRONG>, <STRONG>wscanw</STRONG>, <STRONG>mvscanw</STRONG>
+       and <STRONG>mvwscanw</STRONG> routines to determine the  number  of  fields  which  were
+       mapped in the call.
+
+       Functions  with  a  "mv"  prefix  first perform a cursor movement using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer is null.
+
+
+</PRE><H2><a name="h2-HISTORY">HISTORY</a></H2><PRE>
+       While  <STRONG>scanw</STRONG>  was implemented in 4BSD, none of the BSD releases used it
+       until 4.4BSD (in a game).  That early version of curses was before  the
+       ANSI  C  standard.   It  did  not  use  &lt;varargs.h&gt;,  though  that  was
+       available.  In 1991  (a  couple  of  years  after  SVr4  was  generally
+       available,  and  after  the C standard was published), other developers
+       updated the library, using  &lt;stdarg.h&gt;  internally  in  4.4BSD  curses.
+       Even  with this improvement, BSD curses did not use function prototypes
+       (or even declare functions) in the &lt;curses.h&gt; header until 1992.
+
+       SVr2 documented <STRONG>scanw</STRONG>, <STRONG>wscanw</STRONG> tersely as  "scanf  through  <EM>stdscr</EM>"  and
+       tersely as "scanf through <EM>win</EM>", respectively.
+
+       SVr3 added <STRONG>mvscanw</STRONG>, and <STRONG>mvwscanw</STRONG>, with a three-line summary saying that
+       they were analogous to <STRONG>scanf(3)</STRONG>, explaining that the string which would
+       be  output  from  <STRONG>scanf(3)</STRONG> would instead be output using <STRONG>waddstr</STRONG> on the
+       given window.  SVr3 also added <STRONG>vwscanw</STRONG>, saying that the third parameter
+       is  a  <STRONG>va_list</STRONG>, defined in &lt;varargs.h&gt;, and referring the reader to the
+       manual  pages  for  <EM>varargs</EM>  and  <STRONG>vprintf</STRONG>  for  detailed  descriptions.
+       (Because the SVr3 documentation does not mention <STRONG>vscanf</STRONG>, that reference
+       to <STRONG>vprintf</STRONG> may not be an error).
+
+       SVr4  added  no  new  variations  of  <STRONG>scanw</STRONG>,  but  provided  for  using
+       &lt;varargs.h&gt; or &lt;stdarg.h&gt; to define the <STRONG>va_list</STRONG> type.
+
+       X/Open  Curses  added  <STRONG>vw_scanw</STRONG>  to  replace  <STRONG>vwscanw</STRONG>, stating that its
+       <STRONG>va_list</STRONG> definition requires &lt;stdarg.h&gt;.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       In this implementation, <STRONG>vw_scanw</STRONG> and <STRONG>vwscanw</STRONG> are equivalent, to support
+       legacy applications.  However, the latter (<STRONG>vwscanw</STRONG>) is obsolete:
+
+       <STRONG>o</STRONG>   The  XSI Curses standard, Issue 4 described these functions, noting
+           that the function <STRONG>vwscanw</STRONG> is marked TO BE WITHDRAWN, and is  to  be
+           replaced by a function <STRONG>vw_scanw</STRONG> using the <STRONG>&lt;stdarg.h&gt;</STRONG> interface.
+
+       <STRONG>o</STRONG>   The  Single  Unix Specification, Version 2 states that <STRONG>vw_scanw</STRONG>  is
+           preferred  to  <STRONG>vwscanw</STRONG>  since   the   latter   requires   including
+           <STRONG>&lt;varargs.h&gt;</STRONG>,  which  cannot be used in the same file as <STRONG>&lt;stdarg.h&gt;</STRONG>.
+           This implementation uses <STRONG>&lt;stdarg.h&gt;</STRONG> for both, because  that  header
+           is included in <STRONG>&lt;curses.h</STRONG>&gt;.
+
+       <STRONG>o</STRONG>   X/Open  Curses,  Issue 5 (December 2007) marked <STRONG>vwscanw</STRONG> (along with
+           <STRONG>vwprintw</STRONG> and the termcap interface) as withdrawn.
+
+       Both XSI and The Single Unix Specification, Version 2 state that  these
+       functions return <STRONG>ERR</STRONG> or <STRONG>OK</STRONG>.
+
+       <STRONG>o</STRONG>   Since  the  underlying  <STRONG>scanf(3)</STRONG>  can  return  the  number of items
+           scanned, and the SVr4 code was documented to use this feature, this
+           is  probably  an  editing error which was introduced in XSI, rather
+           than being done intentionally.
+
+       <STRONG>o</STRONG>   This implementation  returns  the  number  of  items  scanned,  for
+           compatibility  with  SVr4  curses.   As of 2018, NetBSD curses also
+           returns the number of  items  scanned.   Both  ncurses  and  NetBSD
+           curses call <STRONG>vsscanf</STRONG> to scan the string, which returns <STRONG>EOF</STRONG> on error.
+
+       <STRONG>o</STRONG>   Portable  applications should only test if the return value is <STRONG>ERR</STRONG>,
+           since the <STRONG>OK</STRONG> value (zero) is likely to be misleading.
+
+           One possible way to get useful results  would  be  to  use  a  "%n"
+           conversion at the end of the format string to ensure that something
+           was processed.

+       The  <STRONG>scroll</STRONG> routine scrolls the window up one line.  This involves mov-
+       ing the lines in the window data structure.  As an optimization, if the
+       scrolling  region  of  the  window  is  the entire screen, the <EM>physical</EM>
+       <EM>screen</EM> may be scrolled at the same time.
+
+       For positive <EM>n</EM>, the <STRONG>scrl</STRONG> and <STRONG>wscrl</STRONG> routines  scroll  the  window  up  <EM>n</EM>
+       lines  (line  <EM>i</EM>+<EM>n</EM> becomes <EM>i</EM>); otherwise scroll the window down <EM>n</EM> lines.
+       This involves moving the lines in the window character image structure.
+       The current cursor position is not changed.
+
+       For these functions to work, scrolling must be enabled via <STRONG>scrollok</STRONG>.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       These routines return <STRONG>ERR</STRONG> upon failure, and <STRONG>OK</STRONG> (SVr4 only specifies "an
+       integer value other than <STRONG>ERR</STRONG>") upon successful completion.
+
+       X/Open defines no error conditions.
+
+       This implementation returns an error if the window pointer is null,  or
+       if scrolling is not enabled in the window, e.g., with <STRONG>scrollok</STRONG>.
+
+
+</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
+       Note that <STRONG>scrl</STRONG> and <STRONG>scroll</STRONG> may be macros.
+
+       The  SVr4  documentation  says  that  the  optimization  of  physically
+       scrolling immediately if the scroll region is the  entire  screen  "is"
+       performed,  not  "may  be" performed.  This implementation deliberately
+       does not guarantee that this will occur, to leave open the  possibility
+       of smarter optimization of multiple scroll actions on the next update.
+
+       Neither  the SVr4 nor the XSI documentation specify whether the current
+       attribute or current color-pair of blanks generated by the scroll func-
+       tion is zeroed.  Under this implementation it is.

+       The slk* functions manipulate the set of soft function-key labels  that
+       exist on many terminals.  For those terminals that do not have soft la-
+       bels, <STRONG>curses</STRONG> takes over the bottom line of <STRONG>stdscr</STRONG>, reducing the size of
+       <STRONG>stdscr</STRONG>  and the variable <STRONG>LINES</STRONG>.  <STRONG>curses</STRONG> standardizes on eight labels of
+       up to eight characters each.  In addition to this, the  ncurses  imple-
+       mentation  supports  a  mode where it simulates 12 labels of up to five
+       characters each.  This is useful for PC-like enduser devices.   ncurses
+       simulates this mode by taking over up to two lines at the bottom of the
+       screen; it does not try to use any hardware support for this mode.
+
+
+</PRE><H3><a name="h3-Initialization">Initialization</a></H3><PRE>
+       The <STRONG>slk_init</STRONG> routine must  be  called  before  <STRONG>initscr</STRONG>  or  <STRONG>newterm</STRONG>  is
+       called.   If  <STRONG>initscr</STRONG> eventually uses a line from <STRONG>stdscr</STRONG> to emulate the
+       soft labels, then <EM>fmt</EM> determines how the labels  are  arranged  on  the
+       screen:
+
+          <STRONG>0</STRONG>  indicates a 3-2-3 arrangement of the labels.
+
+          <STRONG>1</STRONG>  indicates a 4-4 arrangement
+
+          <STRONG>2</STRONG>  indicates the PC-like 4-4-4 mode.
+
+          <STRONG>3</STRONG>  is again the PC-like 4-4-4 mode, but in addition an index line is
+             generated, helping the user to identify the key numbers easily.

+       The <STRONG>slk_set</STRONG> routine (and the <STRONG>slk_wset</STRONG> routine  for  the  wide-character
+       library) has three parameters:
+
+          <EM>labnum</EM>
+               is the label number, from <STRONG>1</STRONG> to <STRONG>8</STRONG> (12 if <EM>fmt</EM> in <STRONG>slk_init</STRONG> is <STRONG>2</STRONG> or
+               <STRONG>3</STRONG>);
+
+          <EM>label</EM>
+               is be the string to put on the label, up to eight (five if  <EM>fmt</EM>
+               in  <STRONG>slk_init</STRONG> is <STRONG>2</STRONG> or <STRONG>3</STRONG>) characters in length.  A null string or
+               a null pointer sets up a blank label.
+
+          <EM>fmt</EM>  is either <STRONG>0</STRONG>, <STRONG>1</STRONG>, or <STRONG>2</STRONG>, indicating whether the  label  is  to  be
+               left-justified,  centered,  or  right-justified,  respectively,
+               within the label.
+
+       The <STRONG>slk_label</STRONG> routine returns the current label for label  number  <EM>lab-</EM>
+       <EM>num</EM>, with leading and trailing blanks stripped.

+       The <STRONG>slk_refresh</STRONG> and <STRONG>slk_noutrefresh</STRONG> routines correspond to the <STRONG>wrefresh</STRONG>
+       and <STRONG>wnoutrefresh</STRONG> routines.
+
+       The <STRONG>slk_clear</STRONG> routine clears the soft labels from the screen.
+
+       The <STRONG>slk_restore</STRONG> routine restores the soft labels to the screen after  a
+       <STRONG>slk_clear</STRONG> has been performed.
+
+       The  <STRONG>slk_touch</STRONG> routine forces all the soft labels to be output the next

+
+       Because  <STRONG>slk_color</STRONG>  accepts  only <STRONG>short</STRONG> (signed 16-bit integer) values,
+       this implementation provides <STRONG>extended_slk_color</STRONG> which accepts an  inte-

+       X/Open  Curses  documents the <EM>opts</EM> argument as reserved for future use,
+       saying that it must be null.  This implementation uses  that  parameter
+       in ABI 6 for the functions which have a color-pair parameter to support
+       extended color pairs.
+
+       For  functions  which modify the color, e.g., <STRONG>slk_attr_set</STRONG>, if <EM>opts</EM>  is
+       set  it  is  treated  as a pointer to <STRONG>int</STRONG>, and used to  set  the  color
+       pair instead of the <STRONG>short</STRONG> pair parameter.

+       The  XSI  Curses  standard,  Issue 4, described the soft-key functions,
+       with some differences from SVr4 curses:
+
+       <STRONG>o</STRONG>   It added functions like the SVr4  attribute-manipulation  functions
+           <STRONG>slk_attron</STRONG>,  <STRONG>slk_attroff</STRONG>, <STRONG>slk_attrset</STRONG>, but which use <STRONG>attr_t</STRONG> parame-
+           ters (rather than <STRONG>chtype</STRONG>), along with a reserved <EM>opts</EM> parameter.
+
+           Two of these new functions (unlike the SVr4 functions) have no pro-
+           vision for color: <STRONG>slk_attr_on</STRONG> and <STRONG>slk_attr_off</STRONG>.
+
+           The third function (<STRONG>slk_attr_set</STRONG>) has a color-pair parameter.
+
+       <STRONG>o</STRONG>   It added <STRONG>const</STRONG> qualifiers to parameters (unnecessarily), and
+
+       <STRONG>o</STRONG>   It added <STRONG>slk_color</STRONG>.
+
+       Although  <STRONG>slk_start</STRONG>  is  declared in the curses header file, it was not
+       documented by SVr4 other than its presence in a list of libtermlib.so.1
+       symbols.  Reading the source code (i.e., Illumos):
+
+       <STRONG>o</STRONG>   <STRONG>slk_start</STRONG> has two parameters:
+
+           <STRONG>o</STRONG>   <EM>ng</EM> (number of groups) and
+
+           <STRONG>o</STRONG>   <EM>gp</EM> (group pointer).
+
+       <STRONG>o</STRONG>   Soft-key groups are an array of <EM>ng</EM> integers.
+
+       <STRONG>o</STRONG>   In  SVr4, <STRONG>slk_init</STRONG> calls <STRONG>slk_start</STRONG> passing a null for <EM>gp</EM>.  For this
+           case, <STRONG>slk_start</STRONG> uses the number of groups <EM>ng</EM> (3 for the 3-2-3  lay-
+           out, 2 for the 4-4 layout) which <STRONG>slk_init</STRONG> provided.
+
+           If  <EM>ng</EM>  is  neither  2 or 3, <STRONG>slk_start</STRONG> checks the terminfo <EM>fln</EM> (la-
+           bel_format) capability, interpreting that as a comma-separated list
+           of numbers, e.g., "3,2,3" for the 3-2-3 layout.
+
+           Finally, if there is no <EM>fln</EM> capability, <STRONG>slk_start</STRONG> returns ERR.
+
+       <STRONG>o</STRONG>   If  <STRONG>slk_start</STRONG>  is given a non-null <EM>gp</EM>, it copies the <EM>ng</EM> elements of
+           the group of soft-keys, up to 16.
+
+           If there are more than 16 elements, <STRONG>slk_start</STRONG> returns an error.
+
+       <STRONG>o</STRONG>   The format codes <STRONG>2</STRONG> and <STRONG>3</STRONG> for <STRONG>slk_init</STRONG>  were  added  by  ncurses  in
+           1996.  PDCurses 2.4 added this feature in 2001.
+
+       The function <STRONG>slk_attr</STRONG> was added by ncurses in 1996.
+
+       X/Open  Curses  does  not  specify a limit for the number of colors and
+       color pairs which a terminal can support.  However, in its use of <STRONG>short</STRONG>
+       for  the  parameters,  it carries over SVr4's implementation detail for
+       the compiled terminfo database, which uses signed 16-bit numbers.  This
+       implementation  provides extended versions of those functions which use
+       <STRONG>int</STRONG> parameters, allowing applications to use larger  color-  and  pair-
+       numbers.

+       This  implementation  can  be  configured to provide a set of functions
+       which improve the ability to manage multiple screens.  This feature can
+       be added to any of the configurations supported by ncurses; it adds new
+       entrypoints without changing the meaning of any of the existing ones.
+
+
+</PRE><H3><a name="h3-IMPROVED-FUNCTIONS">IMPROVED FUNCTIONS</a></H3><PRE>
+       Most of the functions are new versions of existing functions.  A param-
+       eter  is  added  at  the  front  of the parameter list.  It is a SCREEN
+       pointer.
+
+       The existing functions all use the current screen, which  is  a  static
+       variable.  The extended functions use the specified screen, thereby re-
+       ducing the number of variables which must be modified to update  multi-
+       ple screens.
+
+
+</PRE><H3><a name="h3-NEW-FUNCTIONS">NEW FUNCTIONS</a></H3><PRE>
+       Here are the new functions:
+
+       ceiling_panel
+            this returns a pointer to the topmost panel in the given screen.
+
+       ground_panel
+            this returns a pointer to the lowest panel in the given screen.
+
+       new_prescr
+            when  creating  a  new  screen,  the library uses static variables
+            which have been preset, e.g.,  by  <STRONG><A HREF="curs_util.3x.html">use_env(3x)</A></STRONG>,  <STRONG><A HREF="curs_util.3x.html">filter(3x)</A></STRONG>,  etc.
+            With  the  screen-pointer extension, there are situations where it
+            must create a current screen before the unextended  library  does.
+            The  <STRONG>new_prescr</STRONG> function is used internally to handle these cases.
+            It is also provided as an entrypoint to allow applications to cus-
+            tomize the library initialization.
+
+
+</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
+       This extension introduces some new names:
+
+       NCURSES_SP_FUNCS
+            This  is set to the library patch-level number.  In the unextended
+            library, this is zero (0), to make it useful for checking  if  the
+            extension is provided.
+
+       NCURSES_SP_NAME
+            The new functions are named using the macro <EM>NCURSES</EM><STRONG>_</STRONG><EM>SP</EM><STRONG>_</STRONG><EM>NAME</EM>, which
+            hides the actual implementation.  Currently this adds a "_sp" suf-
+            fix  to the name of the unextended function.  This manual page in-
+            dexes the extensions showing the full name.   However  the  proper
+            usage of these functions uses the macro, to provide for the possi-
+            bility of changing the naming convention for specific library con-
+            figurations.
+
+       NCURSES_SP_OUTC
+            This  is  a new function-pointer type to use in the screen-pointer
+            functions where an <EM>NCURSES</EM><STRONG>_</STRONG><EM>OUTC</EM> is used in the unextended library.
+
+       NCURSES_OUTC
+            This is a function-pointer type used for the cases where  a  func-
+            tion passes characters to the output stream, e.g., <STRONG><A HREF="curs_terminfo.3x.html">vidputs(3x)</A></STRONG>.

+       These  routines  are  specific  to ncurses.  They were not supported on
+       Version 7, BSD or System V implementations.  It is recommended that any
+       code  depending  on  ncurses  extensions  be  conditioned  using <EM>NCURS-</EM>

+       These routines are included as a conversion aid for programs  that  use
+       the  <EM>termcap</EM>  library.  Their parameters are the same, but the routines
+       are emulated using the <EM>terminfo</EM> database.  Thus, they can only be  used
+       to  query  the  capabilities  of entries for which a terminfo entry has
+       been compiled.
+
+
+</PRE><H3><a name="h3-Initialization">Initialization</a></H3><PRE>
+       The <STRONG>tgetent</STRONG> routine loads the entry for <EM>name</EM>.  It returns:
+
+          1  on success,
+
+          0  if there is no such entry (or that it is a generic  type,  having
+             too little information for curses applications to run), and
+
+          -1 if the terminfo database could not be found.
+
+       This differs from the <EM>termcap</EM> library in two ways:
+
+          <STRONG>o</STRONG>   The  emulation  ignores  the buffer pointer <EM>bp</EM>.  The <EM>termcap</EM> li-
+              brary would store a copy of the terminal description in the area
+              referenced  by this pointer.  However, ncurses stores its termi-
+              nal descriptions in compiled binary form, which is not the  same
+              thing.
+
+          <STRONG>o</STRONG>   There is a difference in return codes.  The <EM>termcap</EM> library does
+              not check if the terminal description is marked with the <EM>generic</EM>
+              capability,  or  if the terminal description has cursor-address-
+              ing.
+
+
+</PRE><H3><a name="h3-Capability-Values">Capability Values</a></H3><PRE>
+       The <STRONG>tgetflag</STRONG> routine gets the boolean entry for <EM>id</EM>, or zero  if  it  is
+       not available.
+
+       The  <STRONG>tgetnum</STRONG>  routine gets the numeric entry for <EM>id</EM>, or -1 if it is not
+       available.
+
+       The <STRONG>tgetstr</STRONG> routine returns the string entry for <EM>id</EM>, or zero if  it  is
+       not  available.  Use <STRONG>tputs</STRONG> to output the returned string.  The <EM>area</EM> pa-
+       rameter is used as follows:
+
+          <STRONG>o</STRONG>   It is assumed to be the address of a pointer to a buffer managed
+              by the calling application.
+
+          <STRONG>o</STRONG>   However, ncurses checks to ensure that <STRONG>area</STRONG> is not NULL, and al-
+              so that the resulting buffer pointer is  not  NULL.   If  either
+              check fails, the <EM>area</EM> parameter is ignored.
+
+          <STRONG>o</STRONG>   If  the  checks succeed, ncurses also copies the return value to
+              the buffer pointed to by <EM>area</EM>, and the <EM>area</EM> value will be updat-
+              ed to point past the null ending this value.
+
+          <STRONG>o</STRONG>   The  return  value itself is an address in the terminal descrip-
+              tion which is loaded into memory.
+
+       Only the first two characters of the <STRONG>id</STRONG> parameter of <STRONG>tgetflag</STRONG>,  <STRONG>tgetnum</STRONG>
+       and <STRONG>tgetstr</STRONG> are compared in lookups.
+
+
+</PRE><H3><a name="h3-Formatting-Capabilities">Formatting Capabilities</a></H3><PRE>
+       The <STRONG>tgoto</STRONG> routine expands the given capability using the parameters.
+
+       <STRONG>o</STRONG>   Because  the  capability may have padding characters, the output of
+           <STRONG>tgoto</STRONG> should be passed to <STRONG>tputs</STRONG> rather than some other output func-
+           tion such as <STRONG>printf(3)</STRONG>.
+
+       <STRONG>o</STRONG>   While  <STRONG>tgoto</STRONG> is assumed to be used for the two-parameter cursor po-
+           sitioning capability, termcap applications also use it for  single-
+           parameter capabilities.
+
+           Doing this shows a quirk in <STRONG>tgoto</STRONG>: most hardware terminals use cur-
+           sor addressing with <EM>row</EM> first, but the original developers  of  the
+           termcap  interface  chose  to  put the <EM>column</EM> parameter first.  The
+           <STRONG>tgoto</STRONG> function swaps the order of parameters.  It  does  this  also
+           for  calls  requiring  only  a single parameter.  In that case, the
+           first parameter is merely a placeholder.
+
+       <STRONG>o</STRONG>   Normally the ncurses library is compiled with terminfo support.  In
+           that case, <STRONG>tgoto</STRONG> uses <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG> (a more capable formatter).
+
+           However,  <STRONG>tparm</STRONG>  is not a <EM>termcap</EM> feature, and portable <EM>termcap</EM> ap-
+           plications should not rely upon its availability.
+
+       The <STRONG>tputs</STRONG> routine is described on the  <STRONG><A HREF="curs_terminfo.3x.html">curs_terminfo(3x)</A></STRONG>  manual  page.
+       It can retrieve capabilities by either termcap or terminfo name.
+
+
+</PRE><H3><a name="h3-Global-Variables">Global Variables</a></H3><PRE>
+       The  variables <STRONG>PC</STRONG>, <STRONG>UP</STRONG> and <STRONG>BC</STRONG> are set by <STRONG>tgetent</STRONG> to the terminfo entry's
+       data for <STRONG>pad_char</STRONG>, <STRONG>cursor_up</STRONG> and <STRONG>backspace_if_not_bs</STRONG>, respectively.  <STRONG>UP</STRONG>
+       is  not used by ncurses.  <STRONG>PC</STRONG> is used in the <STRONG>tdelay_output</STRONG> function.  <STRONG>BC</STRONG>
+       is used in the <STRONG>tgoto</STRONG> emulation.  The variable <STRONG>ospeed</STRONG> is set by  ncurses
+       in a system-specific coding to reflect the terminal speed.
+
+
+</PRE><H3><a name="h3-Releasing-Memory">Releasing Memory</a></H3><PRE>
+       The  termcap  functions  provide  no  means for freeing memory, because
+       legacy termcap implementations used only the buffer areas  provided  by
+       the  caller  via <STRONG>tgetent</STRONG> and <STRONG>tgetstr</STRONG>.  Those buffers are unused in ter-
+       minfo.
+
+       On the other hand, terminfo allocates memory.  It uses <STRONG>setupterm</STRONG> to re-
+       trieve the data used by <STRONG>tgetent</STRONG> and the functions which return capabil-
+       ity values such as <STRONG>tgetstr</STRONG>.  One could use
+
+            <STRONG>del_curterm(cur_term);</STRONG>
+
+
+       to free this memory, but  there  is  an  additional  complication  with
+       ncurses.   It uses a fixed-size <EM>pool</EM> of storage locations, one per set-
+       ting of the <STRONG>TERM</STRONG> variable when <STRONG>tgetent</STRONG> is called.  The  <STRONG>screen(1)</STRONG>  pro-
+       gram relies upon this arrangement, to improve its performance.
+
+       An  application  which  uses only the low-level termcap functions could
+       free the memory using <STRONG>del_curterm</STRONG>, because the pool is freed using oth-
+       er functions (see <STRONG><A HREF="curs_memleaks.3x.html">curs_memleaks(3x)</A></STRONG>).
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       Except  where  explicitly noted, routines that return an integer return

+       than <STRONG>ERR</STRONG>") upon successful completion.

+       If  you  call <STRONG>tgetstr</STRONG> to fetch <STRONG>ca</STRONG> or any other parameterized string, be

+       not-quite-compatible termcap notation.  This will not cause problems if
+       all you do with it is call <STRONG>tgoto</STRONG> or <STRONG>tparm</STRONG>, which both expand  terminfo-
+       style  strings as terminfo.  (The <STRONG>tgoto</STRONG> function, if configured to sup-

+       style parser if the string does not appear to be terminfo).
+
+       Because terminfo conventions for representing padding in  string  capa-
+       bilities differ from termcap's, users can be surprised:
+
+       <STRONG>o</STRONG>   <STRONG>tputs("50")</STRONG> in a terminfo system will put out a literal "50" rather
+           than busy-waiting for 50 milliseconds.
+
+       <STRONG>o</STRONG>   However, if ncurses is configured to support termcap, it  may  also
+           have been configured to support the BSD-style padding.
+
+           In that case, <STRONG>tputs</STRONG> inspects strings passed to it, looking for dig-
+           its at the beginning of the string.
+
+           <STRONG>tputs("50")</STRONG> in a termcap system may wait for 50 milliseconds rather
+           than put out a literal "50"
+
+       Note  that termcap has nothing analogous to terminfo's <STRONG>sgr</STRONG> string.  One
+       consequence of this is that termcap applications  assume  <STRONG>me</STRONG>  (terminfo
+       <STRONG>sgr0</STRONG>)  does not reset the alternate character set.  This implementation
+       checks for, and modifies the data shown to the termcap interface to ac-
+       commodate termcap's limitation in this respect.

+       These  functions  are  provided for supporting legacy applications, and
+       should not be used in new programs:
+
+       <STRONG>o</STRONG>   The XSI Curses standard, Issue 4 describes these functions.  Howev-
+           er,  they  are  marked TO BE WITHDRAWN and may be removed in future
+           versions.
+
+       <STRONG>o</STRONG>   X/Open Curses, Issue 5 (December 2007) marked the termcap interface
+           (along with <STRONG>vwprintw</STRONG> and <STRONG>vwscanw</STRONG>) as withdrawn.
+
+       Neither  the  XSI Curses standard nor the SVr4 man pages documented the
+       return values of <STRONG>tgetent</STRONG> correctly, though all three were in  fact  re-
+       turned  ever  since SVr1.  In particular, an omission in the XSI Curses
+       documentation has been misinterpreted to mean that <STRONG>tgetent</STRONG>  returns  <STRONG>OK</STRONG>
+       or  <STRONG>ERR</STRONG>.  Because the purpose of these functions is to provide compati-
+       bility with the <EM>termcap</EM> library, that is a defect in XCurses, Issue  4,
+       Version 2 rather than in ncurses.

+       External variables are provided for support of certain termcap applica-
+       tions.  However, termcap applications' use of those variables is poorly
+       documented, e.g., not distinguishing between input and output.  In par-
+       ticular, some applications are reported to declare  and/or  modify  <STRONG>os-</STRONG>
+       <STRONG>peed</STRONG>.
+
+       The  comment that only the first two characters of the <STRONG>id</STRONG> parameter are
+       used escapes many application developers.  The original BSD 4.2 termcap
+       library (and historical relics thereof) did not require a trailing null
+       NUL on the parameter name passed  to  <STRONG>tgetstr</STRONG>,  <STRONG>tgetnum</STRONG>  and  <STRONG>tgetflag</STRONG>.
+       Some  applications  assume  that the termcap interface does not require
+       the trailing NUL for the parameter name.  Taking into account these is-
+       sues:
+
+       <STRONG>o</STRONG>   As  a  special  case,  <STRONG>tgetflag</STRONG>  matched against a single-character
+           identifier provided that was at the end of  the  terminal  descrip-
+           tion.  You should not rely upon this behavior in portable programs.
+           This implementation disallows matches against single-character  ca-
+           pability names.
+
+       <STRONG>o</STRONG>   This  implementation  disallows  matches  by  the termcap interface
+           against extended capability names which are longer than two charac-
+           ters.
+
+       The BSD termcap function <STRONG>tgetent</STRONG> returns the text of a termcap entry in
+       the buffer passed as an argument.  This library  (like  other  terminfo
+       implementations) does not store terminal descriptions as text.  It sets
+       the buffer contents to a null-terminated string.
+
+
+</PRE><H3><a name="h3-Other-Compatibility">Other Compatibility</a></H3><PRE>
+       This library includes a termcap.h header, for compatibility with  other
+       implementations.   But  the header is rarely used because the other im-
+       plementations are not strictly compatible.
+
+       The original BSD termcap (through 4.3BSD) had no header file which gave
+       function prototypes, because that was a feature of ANSI C.  BSD termcap
+       was written several years before C was  standardized.   However,  there
+       were two different termcap.h header files in the BSD sources:
+
+       <STRONG>o</STRONG>   One  was used internally by the <STRONG>jove</STRONG> editor in 2BSD through 4.4BSD.
+           It defined global symbols for the termcap variables which it used.
+
+       <STRONG>o</STRONG>   The other appeared in 4.4BSD Lite Release 2 (mid-1993) as  part  of
+           <EM>libedit</EM> (also known as the <EM>editline</EM> library).  The CSRG source his-
+           tory shows that this was added in  mid-1992.   The  <EM>libedit</EM>  header
+           file  was used internally, as a convenience for compiling the <EM>edit-</EM>
+           <EM>line</EM> library.  It declared function prototypes, but no global vari-
+           ables.
+
+       The  header  file from <EM>libedit</EM> was added to NetBSD's termcap library in
+       mid-1994.
+
+       Meanwhile, GNU termcap was under development, starting  in  1990.   The
+       first  release  (termcap 1.0) in 1991 included a termcap.h header.  The
+       second release (termcap 1.1) in September 1992 modified the  header  to
+       use <STRONG>const</STRONG> for the function prototypes in the header where one would ex-
+       pect the parameters to be read-only.  This was a difference versus  the
+       original  BSD  termcap.   The prototype for <STRONG>tputs</STRONG> also differed, but in
+       that instance, it was <EM>libedit</EM> which differed from BSD termcap.
+
+       A copy of GNU termcap 1.3 was bundled with <EM>bash</EM> in mid-1993, to support
+       the <STRONG>readline(3)</STRONG> library.
+
+       A  termcap.h  file was provided in ncurses 1.8.1 (November 1993).  That
+       reflected influence by <STRONG>emacs(1)</STRONG> (rather than <STRONG>jove(1)</STRONG>) and GNU termcap:
+
+       <STRONG>o</STRONG>   it provided declarations for a few global symbols used by <STRONG>emacs</STRONG>
+
+       <STRONG>o</STRONG>   it provided function prototypes (using <STRONG>const</STRONG>).
+
+       <STRONG>o</STRONG>   a prototype for <STRONG>tparam</STRONG> (a GNU termcap feature) was provided.
+
+       Later (in mid-1996) the <STRONG>tparam</STRONG> function was removed from ncurses.  As a
+       result,  there are differences between any of the four implementations,
+       which must be taken into account by programs which can  work  with  all
+       termcap library interfaces.

+       These  low-level  routines must be called by programs that have to deal
+       directly with the <STRONG>terminfo</STRONG> database to handle certain terminal capabil-
+       ities, such as programming function keys.  For all other functionality,
+       <STRONG>curses</STRONG> routines are more suitable and their use is recommended.
+
+       None of these functions use  (or  are  aware  of)  multibyte  character
+       strings such as UTF-8:
+
+       <STRONG>o</STRONG>   capability names use the POSIX portable character set
+
+       <STRONG>o</STRONG>   capability  string  values  have  no  associated encoding; they are
+           strings of 8-bit characters.
+
+
+</PRE><H3><a name="h3-Initialization">Initialization</a></H3><PRE>
+       Initially, <STRONG>setupterm</STRONG> should be called.  The high-level curses functions
+       <STRONG>initscr</STRONG>  and  <STRONG>newterm</STRONG> call <STRONG>setupterm</STRONG> to initialize the low-level set of
+       terminal-dependent variables [listed in <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>].
+
+       Applications can use the terminal  capabilities  either  directly  (via
+       header  definitions),  or by special functions.  The header files <STRONG>curs-</STRONG>
+       <STRONG>es.h</STRONG> and <STRONG>term.h</STRONG> should be included (in this order) to get  the  defini-
+       tions for these strings, numbers, and flags.
+
+       The  <STRONG>terminfo</STRONG>  variables <STRONG>lines</STRONG> and <STRONG>columns</STRONG> are initialized by <STRONG>setupterm</STRONG>
+       as follows:
+
+       <STRONG>o</STRONG>   If <STRONG>use_env(FALSE)</STRONG> has been called, values  for  <STRONG>lines</STRONG>  and  <STRONG>columns</STRONG>
+           specified in <STRONG>terminfo</STRONG> are used.
+
+       <STRONG>o</STRONG>   Otherwise,  if  the  environment variables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> exist,
+           their values are used.  If these environment variables do not exist
+           and  the program is running in a window, the current window size is
+           used.  Otherwise, if the environment variables do  not  exist,  the
+           values for <STRONG>lines</STRONG> and <STRONG>columns</STRONG> specified in the <STRONG>terminfo</STRONG> database are
+           used.
+
+       Parameterized strings should be passed  through  <STRONG>tparm</STRONG>  to  instantiate
+       them.   All  <STRONG>terminfo</STRONG> strings (including the output of <STRONG>tparm</STRONG>) should be
+       printed with <STRONG>tputs</STRONG> or <STRONG>putp</STRONG>.  Call <STRONG>reset_shell_mode</STRONG> to restore  the  tty
+       modes before exiting [see <STRONG><A HREF="curs_kernel.3x.html">curs_kernel(3x)</A></STRONG>].
+
+       Programs which use cursor addressing should
+
+       <STRONG>o</STRONG>   output <STRONG>enter_ca_mode</STRONG> upon startup and
+
+       <STRONG>o</STRONG>   output <STRONG>exit_ca_mode</STRONG> before exiting.
+
+       Programs which execute shell subprocesses should
+
+       <STRONG>o</STRONG>   call  <STRONG>reset_shell_mode</STRONG>  and output <STRONG>exit_ca_mode</STRONG> before the shell is
+           called and
+
+       <STRONG>o</STRONG>   output <STRONG>enter_ca_mode</STRONG> and call <STRONG>reset_prog_mode</STRONG> after returning  from

+       The  <STRONG>setupterm</STRONG> routine reads in the <STRONG>terminfo</STRONG> database, initializing the
+       <STRONG>terminfo</STRONG> structures, but does not  set  up  the  output  virtualization
+       structures used by <STRONG>curses</STRONG>.  These are its parameters:
+
+          <EM>term</EM> is the terminal type, a character string.  If <EM>term</EM> is null, the
+               environment variable <STRONG>TERM</STRONG> is used.
+
+          <EM>filedes</EM>
+               is the file descriptor used for all output.
+
+          <EM>errret</EM>
+               points to an optional location where an error status can be re-
+               turned  to  the  caller.  If <EM>errret</EM> is not null, then <STRONG>setupterm</STRONG>
+               returns <STRONG>OK</STRONG> or <STRONG>ERR</STRONG> and stores a  status  value  in  the  integer
+               pointed  to by <EM>errret</EM>.  A return value of <STRONG>OK</STRONG> combined with sta-
+               tus of <STRONG>1</STRONG> in <EM>errret</EM> is normal.
+
+               If <STRONG>ERR</STRONG> is returned, examine <EM>errret</EM>:
+
+               <STRONG>1</STRONG>    means that the terminal is hardcopy, cannot  be  used  for
+                    curses applications.
+
+                    <STRONG>setupterm</STRONG>  determines  if  the entry is a hardcopy type by
+                    checking the <STRONG>hc</STRONG> (<STRONG>hardcopy</STRONG>) capability.
+
+               <STRONG>0</STRONG>    means that the terminal could not be found, or that it  is
+                    a  generic  type, having too little information for curses
+                    applications to run.
+
+                    <STRONG>setupterm</STRONG> determines if the entry is  a  generic  type  by

+
+               <STRONG>-1</STRONG>   means that the <STRONG>terminfo</STRONG> database could not be found.
+
+               If <EM>errret</EM> is null, <STRONG>setupterm</STRONG> prints an error message upon find-
+               ing an error and exits.  Thus, the simplest call is:

+                     <STRONG>setupterm((char</STRONG> <STRONG>*)0,</STRONG> <STRONG>1,</STRONG> <STRONG>(int</STRONG> <STRONG>*)0);</STRONG>,

+       The <STRONG>setupterm</STRONG> routine stores its information about the  terminal  in  a
+       <STRONG>TERMINAL</STRONG>  structure  pointed to by the global variable <STRONG>cur_term</STRONG>.  If it
+       detects an error, or decides that the terminal is unsuitable  (hardcopy
+       or  generic),  it discards this information, making it not available to
+       applications.
+
+       If <STRONG>setupterm</STRONG> is called repeatedly for the same terminal type,  it  will
+       reuse  the  information.   It maintains only one copy of a given termi-
+       nal's capabilities in memory.  If it is called for  different  terminal
+       types,  <STRONG>setupterm</STRONG>  allocates new storage for each set of terminal capa-
+       bilities.
+
+       The <STRONG>set_curterm</STRONG> routine sets <STRONG>cur_term</STRONG> to <EM>nterm</EM>, and makes  all  of  the
+       <STRONG>terminfo</STRONG>  boolean,  numeric,  and  string variables use the values from
+       <EM>nterm</EM>.  It returns the old value of <STRONG>cur_term</STRONG>.
+
+       The <STRONG>del_curterm</STRONG> routine frees the space pointed to by <EM>oterm</EM>  and  makes
+       it available for further use.  If <EM>oterm</EM> is the same as <STRONG>cur_term</STRONG>, refer-
+       ences to any of the <STRONG>terminfo</STRONG> boolean,  numeric,  and  string  variables
+       thereafter  may  refer  to  invalid  memory locations until another <STRONG>se-</STRONG>
+       <STRONG>tupterm</STRONG> has been called.
+
+       The <STRONG>restartterm</STRONG> routine is similar to  <STRONG>setupterm</STRONG>  and  <STRONG>initscr</STRONG>,  except
+       that it is called after restoring memory to a previous state (for exam-
+       ple, when reloading a game saved as a core  image  dump).   <STRONG>restartterm</STRONG>
+       assumes  that the windows and the input and output options are the same
+       as when memory was saved, but the terminal type and baud  rate  may  be
+       different.   Accordingly,  <STRONG>restartterm</STRONG>  saves  various  tty state bits,
+       calls <STRONG>setupterm</STRONG>, and then restores the bits.

+       Application developers should keep in mind these quirks of  the  inter-
+       face:
+
+       <STRONG>o</STRONG>   Although  <STRONG>tparm</STRONG>'s actual parameters may be integers or strings, the
+           prototype expects <STRONG>long</STRONG> (integer) values.
+
+       <STRONG>o</STRONG>   Aside from the <STRONG>set_attributes</STRONG> (<STRONG>sgr</STRONG>) capability, most terminal capa-
+           bilities require no more than one or two parameters.
+
+       <STRONG>o</STRONG>   Padding  information  is  ignored  by  <STRONG>tparm</STRONG>;  it is interpreted by
+           <STRONG>tputs</STRONG>.
+
+       <STRONG>o</STRONG>   The capability string is  null-terminated.   Use  "\200"  where  an
+           ASCII NUL is needed in the output.
+
+       <STRONG>tiparm</STRONG>  is  a  newer  form of <STRONG>tparm</STRONG> which uses <EM>&lt;stdarg.h&gt;</EM> rather than a
+       fixed-parameter list.  Its numeric parameters are integers (int) rather
+       than longs.
+
+
+</PRE><H3><a name="h3-Output-Functions">Output Functions</a></H3><PRE>
+       The  <STRONG>tputs</STRONG>  routine  applies padding information (i.e., by interpreting
+       marker embedded in the terminfo capability such as  "$&lt;5&gt;"  as  5  mil-
+       liseconds) to the string <EM>str</EM> and outputs it:
+
+       <STRONG>o</STRONG>   The  <EM>str</EM> parameter must be a terminfo string variable or the return
+           value from <STRONG>tparm</STRONG>, <STRONG>tiparm</STRONG>, <STRONG>tgetstr</STRONG>, or <STRONG>tgoto</STRONG>.
+
+           The <STRONG>tgetstr</STRONG> and <STRONG>tgoto</STRONG> functions are part of the <EM>termcap</EM>  interface,
+           which  happens to share this function name with the <EM>terminfo</EM> inter-
+           face.
+
+       <STRONG>o</STRONG>   <EM>affcnt</EM> is the number of lines affected, or 1 if not applicable.
+
+       <STRONG>o</STRONG>   <EM>putc</EM> is a <STRONG>putchar</STRONG>-like routine to which the characters are  passed,
+           one at a time.
+
+       The  <STRONG>putp</STRONG> routine calls <STRONG>tputs(</STRONG><EM>str</EM><STRONG>,</STRONG> <STRONG>1,</STRONG> <STRONG>putchar)</STRONG>.  The output of <STRONG>putp</STRONG> al-
+       ways goes to <STRONG>stdout</STRONG>, rather than the <EM>filedes</EM> specified in <STRONG>setupterm</STRONG>.
+
+       The <STRONG>vidputs</STRONG> routine displays the string on the terminal  in  the  video
+       attribute mode <EM>attrs</EM>, which is any combination of the attributes listed
+       in <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>.  The characters are passed to the  <STRONG>putchar</STRONG>-like  routine
+       <EM>putc</EM>.
+
+       The <STRONG>vidattr</STRONG> routine is like the <STRONG>vidputs</STRONG> routine, except that it outputs
+       through <STRONG>putchar</STRONG>.
+
+       The <STRONG>vid_attr</STRONG> and <STRONG>vid_puts</STRONG> routines correspond to vidattr  and  vidputs,
+       respectively.   They  use a set of arguments for representing the video
+       attributes plus color, i.e.,
+
+       <STRONG>o</STRONG>   <EM>attrs</EM> of type <STRONG>attr_t</STRONG> for the attributes and
+
+       <STRONG>o</STRONG>   <EM>pair</EM> of type <STRONG>short</STRONG> for the color-pair number.
+
+       The <STRONG>vid_attr</STRONG> and <STRONG>vid_puts</STRONG> routines are designed to  use  the  attribute
+       constants with the <STRONG>WA_</STRONG> prefix.
+
+       X/Open  Curses  reserves  the <EM>opts</EM> argument for future use, saying that
+       applications must provide a null pointer for that argument.  As an  ex-
+       tension,  this  implementation  allows  <EM>opts</EM> to be used as a pointer to
+       <STRONG>int</STRONG>, which overrides the <EM>pair</EM> (<STRONG>short</STRONG>) argument.
+
+       The <STRONG>mvcur</STRONG> routine provides low-level cursor motion.   It  takes  effect
+       immediately (rather than at the next refresh).
+
+       While <STRONG>putp</STRONG> and <STRONG>mvcur</STRONG> are low-level functions which do not use the high-

+       Older  versions  of  <STRONG>ncurses</STRONG> assumed that the file descriptor passed to
+       <STRONG>setupterm</STRONG> from <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG> uses buffered I/O, and would write to
+       the  corresponding stream.  In addition to the limitation that the ter-
+       minal was left in block-buffered mode on exit (like System  V  curses),
+       it  was  problematic  because  <STRONG>ncurses</STRONG>  did not allow a reliable way to
+       cleanup on receiving SIGTSTP.
+
+       The current version (ncurses6) uses output buffers managed directly  by
+       <STRONG>ncurses</STRONG>.  Some of the low-level functions described in this manual page
+       write to the standard output.  They are not signal-safe.  The high-lev-
+       el functions in <STRONG>ncurses</STRONG> use alternate versions of these functions using
+       the more reliable buffering scheme.
+
+
+</PRE><H3><a name="h3-Function-prototypes">Function prototypes</a></H3><PRE>
+       The X/Open Curses prototypes are based on the SVr4 curses header decla-
+       rations,  which  were defined at the same time the C language was first
+       standardized in the late 1980s.
+
+       <STRONG>o</STRONG>   X/Open Curses uses <STRONG>const</STRONG>  less  effectively  than  a  later  design
+           might,  in  some cases applying it needlessly to values are already
+           constant, and in most cases overlooking parameters  which  normally
+           would  use <STRONG>const</STRONG>.  Using constant parameters for functions which do
+           not use <STRONG>const</STRONG> may prevent the program from compiling.  On the other
+           hand, <EM>writable</EM> <EM>strings</EM> are an obsolescent feature.
+
+           As  an  extension,  this implementation can be configured to change
+           the function prototypes to use the <STRONG>const</STRONG> keyword.  The ncurses  ABI
+           6 enables this feature by default.
+
+       <STRONG>o</STRONG>   X/Open  Curses  prototypes <STRONG>tparm</STRONG> with a fixed number of parameters,
+           rather than a variable argument list.
+
+           This implementation uses a variable argument list, but can be  con-
+           figured  to  use  the  fixed-parameter list.  Portable applications
+           should provide 9 parameters after the format; zeroes are  fine  for
+           this purpose.
+
+           In  response  to review comments by Thomas E. Dickey, X/Open Curses
+           Issue 7 proposed the <STRONG>tiparm</STRONG> function in mid-2009.
+

+       If configured to use the terminal-driver, e.g., for the MinGW port,
+
+       <STRONG>o</STRONG>   <STRONG>setupterm</STRONG> interprets a missing/empty TERM variable as  the  special
+           value "unknown".
+
+       <STRONG>o</STRONG>   <STRONG>setupterm</STRONG>  allows explicit use of the the windows console driver by
+           checking if $TERM is set to "#win32con" or an abbreviation of  that
+           string.
+
+
+</PRE><H3><a name="h3-Other-portability-issues">Other portability issues</a></H3><PRE>
+       In  System  V Release 4, <STRONG>set_curterm</STRONG> has an <STRONG>int</STRONG> return type and returns
+       <STRONG>OK</STRONG> or <STRONG>ERR</STRONG>.  We have chosen to implement the X/Open Curses semantics.
+
+       In System V Release 4, the third argument of <STRONG>tputs</STRONG>  has  the  type  <STRONG>int</STRONG>
+       <STRONG>(*putc)(char)</STRONG>.
+
+       At  least one implementation of X/Open Curses (Solaris) returns a value
+       other than <STRONG>OK</STRONG>/<STRONG>ERR</STRONG> from <STRONG>tputs</STRONG>.  That returns the length of  the  string,
+       and does no error-checking.
+
+       X/Open  notes  that after calling <STRONG>mvcur</STRONG>, the curses state may not match
+       the actual terminal state, and that an application should touch and re-
+       fresh the window before resuming normal curses calls.  Both <STRONG>ncurses</STRONG> and
+       System V Release 4 curses implement <STRONG>mvcur</STRONG> using the SCREEN  data  allo-
+       cated  in  either  <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>.  So though it is documented as a
+       terminfo function, <STRONG>mvcur</STRONG> is really a curses function which is not  well
+       specified.
+
+       X/Open  states that the old location must be given for <STRONG>mvcur</STRONG>.  This im-
+       plementation allows the caller to use -1's for the old  ordinates.   In
+       that case, the old location is unknown.

+       This  implementation  can  be configured to provide rudimentary support
+       for multi-threaded applications.  This makes a  different  set  of  li-
+       braries, e.g., <STRONG>libncursest</STRONG> since the binary interfaces are different.
+
+       Rather  than  modify  the interfaces to pass a thread specifier to each
+       function, it adds a few functions which can be used in  any  configura-
+       tion  which  hide  the  mutex's needed to prevent concurrent use of the
+       global variables when configured for threading.
+
+       In addition to forcing access to members of the <STRONG>WINDOW</STRONG> structure to  be
+       via  functions  (see <STRONG><A HREF="curs_opaque.3x.html">curs_opaque(3x)</A></STRONG>), it makes functions of the common
+       global variables, e.g., COLORS,  COLOR_PAIRS,  COLS,  ESCDELAY,  LINES,
+       TABSIZE  curscr, newscr and ttytype.  Those variables are maintained as
+       read-only values, stored in the <STRONG>SCREEN</STRONG> structure.
+
+       Even this is not enough to make a thread-safe application using curses.
+       A multi-threaded application would be expected to have threads updating
+       separate windows (within the same  device),  or  updating  on  separate
+       screens  (on  different  devices).  Also, a few of the global variables
+       are considered writable by some applications.  The functions  described
+       here address these special situations.
+
+       The ESCDELAY and TABSIZE global variables are modified by some applica-
+       tions.  To modify them in any configuration, use  the  <STRONG>set_escdelay</STRONG>  or
+       <STRONG>set_tabsize</STRONG> functions.  Other global variables are not modifiable.
+
+       The <STRONG>get_escdelay</STRONG> function returns the value for ESCDELAY.
+
+       The  <STRONG>use_window</STRONG> and <STRONG>use_screen</STRONG> functions provide coarse granularity mu-
+       texes for their respective <STRONG>WINDOW</STRONG> and <STRONG>SCREEN</STRONG> parameters, and call a us-
+       er-supplied  function,  passing  it a <EM>data</EM> parameter, and returning the
+       value from the user-supplied function to the application.

+</PRE><H3><a name="h3-USAGE">USAGE</a></H3><PRE>
+       All of the ncurses library functions assume that the locale is not  al-
+       tered during operation.  In addition, they use data which is maintained
+       within a hierarchy of scopes.
+
+          <STRONG>o</STRONG>   global data, e.g., used in the low-level terminfo or termcap in-
+              terfaces.
+
+          <STRONG>o</STRONG>   terminal data, e.g., associated with a call to <STRONG>set_curterm</STRONG>.  The
+              terminal data are initialized when screens are created.
+
+          <STRONG>o</STRONG>   screen data, e.g., associated with a call to <STRONG>newterm</STRONG> or <STRONG>initscr</STRONG>.
+
+          <STRONG>o</STRONG>   window data, e.g., associated with a call to <STRONG>newwin</STRONG>  or  <STRONG>subwin</STRONG>.
+              Windows  are  associated with screens.  Pads are not necessarily
+              associated with a particular screen.
+
+              Most curses applications operate on one or more windows within a
+              single screen.
+
+          <STRONG>o</STRONG>   reentrant, i.e., it uses only the data passed as parameters.
+
+       This  table lists the scope of data used for each symbol in the ncurses
+       library when it is configured to support threading:

+       The <STRONG>touchwin</STRONG> and <STRONG>touchline</STRONG> routines throw away all optimization  infor-
+       mation about which parts of the window have been touched, by pretending
+       that the entire window has been drawn on.  This is sometimes  necessary
+       when  using  overlapping  windows, since a change to one window affects
+       the other window, but the records of which lines have been  changed  in
+       the other window do not reflect the change.  The routine <STRONG>touchline</STRONG> only
+       pretends that <EM>count</EM> lines have been changed, beginning with line <EM>start</EM>.
+
+       The <STRONG>untouchwin</STRONG> routine marks all lines in the window as unchanged since
+       the last call to <STRONG>wrefresh</STRONG>.
+
+       The  <STRONG>wtouchln</STRONG>  routine makes <EM>n</EM> lines in the window, starting at line <EM>y</EM>,
+       look as if they have (<EM>changed</EM><STRONG>=1</STRONG>) or have not (<EM>changed</EM><STRONG>=0</STRONG>)  been  changed
+       since the last call to <STRONG>wrefresh</STRONG>.
+
+       The <STRONG>is_linetouched</STRONG> and <STRONG>is_wintouched</STRONG> routines return <STRONG>TRUE</STRONG> if the speci-
+       fied line/window was modified since the last call to  <STRONG>wrefresh</STRONG>;  other-
+       wise  they  return  <STRONG>FALSE</STRONG>.   In addition, <STRONG>is_linetouched</STRONG> returns <STRONG>ERR</STRONG> if
+       <EM>line</EM> is not valid for the given window.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       All routines return the integer <STRONG>ERR</STRONG> upon failure and an  integer  value
+       other  than  <STRONG>ERR</STRONG>  upon successful completion, unless otherwise noted in
+       the preceding routine descriptions.
+
+       X/Open does not define any error conditions.  In this implementation
+
+          <STRONG>is_linetouched</STRONG>
+               returns an error if the window pointer is null, or if the  line
+               number is outside the window.
+
+               The constant <STRONG>ERR</STRONG> is distinct from <STRONG>TRUE</STRONG> and <STRONG>FALSE</STRONG>, which are the
+               normal return values of this function.   Because  the  function
+               returns a <STRONG>bool</STRONG>, returning <STRONG>ERR</STRONG> (which is neither <STRONG>TRUE</STRONG> nor <STRONG>FALSE</STRONG>)
+               may not be supported by the compiler.
+
+               To provide error-checking and also match  the  X/Open  function
+               prototype, the <STRONG>ERR</STRONG> is provided by a macro named <STRONG>is_linetouched</STRONG>.
+               The actual function returns <STRONG>FALSE</STRONG> when it detects an error.
+
+          <STRONG>wtouchln</STRONG>
+               returns an error if the window pointer is null, or if the  line
+               number is outside the window.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       These  functions  were  introduced  by SVr4.  The Solaris curses header
+       file, for instance, defines both an actual function and macro for each.
+       The  macros  give the same result as the actual functions.  SVr4 curses
+       does not check the window parameter <EM>win</EM> to ensure that it is not  <STRONG>NULL</STRONG>;
+       otherwise this implementation behaves the same as SVr4.
+
+       The XSI Curses standard, Issue 4 describes these functions, but defines
+       no error conditions.

+</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
+       The <EM>curses</EM> <EM>trace</EM> routines are used for debugging the ncurses libraries,
+       as well as applications which use the ncurses libraries.  Some  limita-
+       tions apply:
+
+       <STRONG>o</STRONG>   Aside from <STRONG>curses_trace</STRONG>, the other functions are normally available
+           only with the debugging library e.g., <STRONG>libncurses_g.a</STRONG>.
+
+           All of the trace functions may be compiled into any model  (shared,
+           static, profile) by defining the symbol <STRONG>TRACE</STRONG>.
+
+       <STRONG>o</STRONG>   Additionally,  the  functions  which use <STRONG>cchar_t</STRONG> are only available
+           with the wide-character configuration of the libraries.
+
+
+</PRE><H3><a name="h3-Functions">Functions</a></H3><PRE>
+       The principal parts of this interface are
+
+       <STRONG>o</STRONG>   <STRONG>curses_trace</STRONG>, which selectively enables different tracing features,
+           and
+
+       <STRONG>o</STRONG>   <STRONG>_tracef</STRONG>, which writes formatted data to the <EM>trace</EM> file.
+
+           The other functions either return a pointer to a string-area (allo-
+           cated by the corresponding function), or return no value  (such  as
+           <STRONG>_tracedump</STRONG>,  which  implements  the  screen dump for <STRONG>TRACE_UPDATE</STRONG>).
+           The caller should not free these strings, since the  allocation  is
+           reused on successive calls.  To work around the problem of a single
+           string-area per  function,  some  use  a  buffer-number  parameter,
+           telling the library to allocate additional string-areas.
+
+       The <STRONG>curses_trace</STRONG> function is always available, whether or not the other
+       trace functions are available:
+
+       <STRONG>o</STRONG>   If tracing is available, calling <STRONG>curses_trace</STRONG> with a nonzero param-
+           eter updates the trace mask, and returns the previous trace mask.
+
+           When the trace mask is nonzero, ncurses creates the file "trace" in
+           the current directory for output.  If the file already  exists,  no
+           tracing is done.
+
+       <STRONG>o</STRONG>   If tracing is not available, <STRONG>curses_trace</STRONG> returns zero (0).
+
+
+</PRE><H3><a name="h3-Trace-Parameter">Trace Parameter</a></H3><PRE>
+       The  trace  parameter  is  formed  by  OR'ing  values  from the list of
+       <STRONG>TRACE_</STRONG><EM>xxx</EM> definitions in <STRONG>&lt;curses.h&gt;</STRONG>.  These include:
+
+       <STRONG>TRACE_DISABLE</STRONG>
+            turn off tracing by passing a zero parameter.
+
+            The library flushes the output file, but retains an open  file-de-
+            scriptor  to the trace file so that it can resume tracing later if
+            a nonzero parameter is passed to the <STRONG>curses_trace</STRONG> function.
+
+       <STRONG>TRACE_TIMES</STRONG>
+            trace user and system times of updates.
+
+       <STRONG>TRACE_TPUTS</STRONG>
+            trace <STRONG><A HREF="curs_terminfo.3x.html">tputs(3x)</A></STRONG> calls.
+
+       <STRONG>TRACE_UPDATE</STRONG>
+            trace update actions, old &amp; new screens.
+
+       <STRONG>TRACE_MOVE</STRONG>
+            trace cursor movement and scrolling.
+
+       <STRONG>TRACE_CHARPUT</STRONG>
+            trace all character outputs.
+
+       <STRONG>TRACE_ORDINARY</STRONG>
+            trace all update actions.  The old and  new  screen  contents  are
+            written to the trace file for each refresh.
+
+       <STRONG>TRACE_CALLS</STRONG>
+            trace  all curses calls.  The parameters for each call are traced,
+            as well as return values.
+
+       <STRONG>TRACE_VIRTPUT</STRONG>
+            trace virtual character puts, i.e., calls to <STRONG>addch</STRONG>.
+
+       <STRONG>TRACE_IEVENT</STRONG>
+            trace low-level input processing, including timeouts.
+
+       <STRONG>TRACE_BITS</STRONG>
+            trace state of TTY control bits.
+
+       <STRONG>TRACE_ICALLS</STRONG>
+            trace internal/nested calls.
+
+       <STRONG>TRACE_CCALLS</STRONG>
+            trace per-character calls.
+
+       <STRONG>TRACE_DATABASE</STRONG>
+            trace read/write of terminfo/termcap data.
+
+       <STRONG>TRACE_ATTRS</STRONG>
+            trace changes to video attributes and colors.
+
+       <STRONG>TRACE_MAXIMUM</STRONG>
+            maximum trace level, enables all of the separate trace features.
+
+       Some tracing features are enabled whenever the  <STRONG>curses_trace</STRONG>  parameter
+       is  nonzero.   Some features overlap.  The specific names are used as a
+       guideline.

+       These functions check the <STRONG>NCURSES_TRACE</STRONG> environment  variable,  to  set

+       The  command-line  utilities  such  as  <STRONG><A HREF="tic.1m.html">tic(1)</A></STRONG> provide a verbose option

+       tion.   Both  of  these  (<STRONG>-v</STRONG>  and  <STRONG>curses_trace</STRONG>)  use the same variable
+       (<STRONG>_nc_tracing</STRONG>), which determines the messages which are written.
+
+       Because the command-line utilities may  call  initialization  functions
+       such  as <STRONG>setupterm</STRONG>, <STRONG>tgetent</STRONG> or <STRONG>use_extended_names</STRONG>, some of their debug-
+       ging output may be directed to the <EM>trace</EM> file if the <STRONG>NCURSES_TRACE</STRONG>  en-
+       vironment variable is set:
+

+
+       <STRONG>o</STRONG>   messages produced by the underlying library are written to <EM>trace</EM>.
+
+       If  ncurses  is built without tracing, none of the latter are produced,

+       These  functions  are not part of the XSI interface.  Some other curses
+       implementations are known to have similar features, but  they  are  not
+       compatible with ncurses:
+
+       <STRONG>o</STRONG>   SVr4  provided  <STRONG>traceon</STRONG>  and <STRONG>traceoff</STRONG>, to control whether debugging
+           information was written to the "trace" file.  While  the  functions
+           were  always  available, this feature was only enabled if <STRONG>DEBUG</STRONG> was
+           defined when building the library.
+
+           The SVr4 tracing feature is undocumented.
+
+       <STRONG>o</STRONG>   PDCurses provides <STRONG>traceon</STRONG> and <STRONG>traceoff</STRONG>, which (like SVr4)  are  al-
+           ways  available, and enable tracing to the "trace" file only when a
+           debug-library is built.
+
+           PDCurses has a short description of these functions,  with  a  note
+           that  they are not present in X/Open Curses, ncurses or NetBSD.  It
+           does not mention SVr4, but the functions'  inclusion  in  a  header
+           file section labeled "Quasi-standard" hints at the origin.
+
+       <STRONG>o</STRONG>   NetBSD  does  not  provide functions for enabling/disabling traces.
+           It  uses  environment   variables   <STRONG>CURSES_TRACE_MASK</STRONG>   and   <STRONG>CURS-</STRONG>
+           <STRONG>ES_TRACE_FILE</STRONG>  to  determine  what is traced, and where the results
+           are written.  This is available only when a debug-library is built.
+
+           The NetBSD tracing feature is undocumented.
+
+       A few ncurses functions are not  provided  when  symbol  versioning  is
+       used:
+
+           _nc_tracebits, _tracedump, _tracemouse
+
+       The  original  <STRONG>trace</STRONG> routine was deprecated because it often conflicted
+       with application names.

+       The <STRONG>unctrl</STRONG> routine returns a character string which is a printable rep-
+       resentation of the character <EM>c</EM>, ignoring attributes.   Control  charac-
+       ters  are  displayed  in the <STRONG>^</STRONG><EM>X</EM> notation.  Printing characters are dis-
+       played as is.  The corresponding <STRONG>wunctrl</STRONG> returns a printable  represen-
+       tation of a wide character.
+
+
+</PRE><H3><a name="h3-keyname_key_name">keyname/key_name</a></H3><PRE>
+       The <STRONG>keyname</STRONG> routine returns a character string corresponding to the key
+       <EM>c</EM>:
+
+       <STRONG>o</STRONG>   Printable characters are displayed as themselves, e.g., a one-char-
+           acter string containing the key.
+
+       <STRONG>o</STRONG>   Control characters are displayed in the <STRONG>^</STRONG><EM>X</EM> notation.
+
+       <STRONG>o</STRONG>   DEL (character 127) is displayed as <STRONG>^?</STRONG>.
+
+       <STRONG>o</STRONG>   Values  above 128 are either meta characters (if the screen has not
+           been initialized, or if <STRONG><A HREF="curs_inopts.3x.html">meta(3x)</A></STRONG> has been called with a <STRONG>TRUE</STRONG> param-
+           eter),  shown  in the <STRONG>M-</STRONG><EM>X</EM> notation, or are displayed as themselves.
+           In the latter case, the values may not be printable;  this  follows
+           the X/Open specification.
+
+       <STRONG>o</STRONG>   Values above 256 may be the names of the names of function keys.
+
+       <STRONG>o</STRONG>   Otherwise  (if there is no corresponding name) the function returns
+           null, to denote an error.  X/Open also lists an "UNKNOWN  KEY"  re-
+           turn value, which some implementations return rather than null.
+
+       The  corresponding <STRONG>key_name</STRONG> returns a character string corresponding to
+       the wide-character value <EM>w</EM>.  The two functions do not return  the  same
+       set  of strings; the latter returns null where the former would display
+       a meta character.
+
+
+</PRE><H3><a name="h3-filter_nofilter">filter/nofilter</a></H3><PRE>
+       The <STRONG>filter</STRONG> routine, if used, must be called before <STRONG>initscr</STRONG>  or  <STRONG>newterm</STRONG>
+       are called.  Calling <STRONG>filter</STRONG> causes these changes in initialization:
+
+       <STRONG>o</STRONG>   <STRONG>LINES</STRONG> is set to 1;
+
+       <STRONG>o</STRONG>   the  capabilities  <STRONG>clear</STRONG>,  <STRONG>cud1</STRONG>,  <STRONG>cud</STRONG>, <STRONG>cup</STRONG>, <STRONG>cuu1</STRONG>, <STRONG>cuu</STRONG>, <STRONG>vpa</STRONG> are dis-
+           abled;
+
+       <STRONG>o</STRONG>   the capability <STRONG>ed</STRONG> is disabled if <STRONG>bce</STRONG> is set;
+
+       <STRONG>o</STRONG>   and the <STRONG>home</STRONG> string is set to the value of <STRONG>cr</STRONG>.
+
+       The <STRONG>nofilter</STRONG> routine cancels the effect of  a  preceding  <STRONG>filter</STRONG>  call.
+       That  allows  the  caller to initialize a screen on a different device,
+       using a different value of <STRONG>$TERM</STRONG>.  The limitation  arises  because  the
+       <STRONG>filter</STRONG> routine modifies the in-memory copy of the terminal information.
+
+
+</PRE><H3><a name="h3-use_env">use_env</a></H3><PRE>
+       The  <STRONG>use_env</STRONG>  routine,  if  used,  should  be  called before <STRONG>initscr</STRONG> or
+       <STRONG>newterm</STRONG> are called (because those compute the screen size).   It  modi-
+       fies  the way <STRONG>ncurses</STRONG> treats environment variables when determining the
+       screen size.
+
+       <STRONG>o</STRONG>   Normally <STRONG>ncurses</STRONG> looks first  at  the  terminal  database  for  the
+           screen size.
+
+           If  <STRONG>use_env</STRONG>  was called with <STRONG>FALSE</STRONG> for parameter, it stops here un-
+           less <STRONG>use_tioctl</STRONG> was also called with <STRONG>TRUE</STRONG> for parameter.
+
+       <STRONG>o</STRONG>   Then it asks for the screen size via operating  system  calls.   If
+           successful, it overrides the values from the terminal database.
+
+       <STRONG>o</STRONG>   Finally  (unless  <STRONG>use_env</STRONG> was called with <STRONG>FALSE</STRONG> parameter), <STRONG>ncurses</STRONG>
+           examines the <STRONG>LINES</STRONG> or <STRONG>COLUMNS</STRONG> environment variables, using a  value
+           in  those to override the results from the operating system or ter-
+           minal database.
+
+           <STRONG>Ncurses</STRONG> also updates the screen size in response to  <STRONG>SIGWINCH</STRONG>,  un-
+           less overridden by the <STRONG>LINES</STRONG> or <STRONG>COLUMNS</STRONG> environment variables,
+
+
+</PRE><H3><a name="h3-use_tioctl">use_tioctl</a></H3><PRE>
+       The  <STRONG>use_tioctl</STRONG>  routine,  if  used, should be called before <STRONG>initscr</STRONG> or
+       <STRONG>newterm</STRONG> are called (because those  compute  the  screen  size).   After
+       <STRONG>use_tioctl</STRONG>  is  called  with  <STRONG>TRUE</STRONG> as an argument, <STRONG>ncurses</STRONG> modifies the
+       last step in its computation of screen size as follows:
+
+       <STRONG>o</STRONG>   checks if the <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> environment variables are set to  a
+           number greater than zero.
+
+       <STRONG>o</STRONG>   for  each,  <STRONG>ncurses</STRONG>  updates the corresponding environment variable
+           with the value that it has obtained via operating  system  call  or
+           from the terminal database.
+
+       <STRONG>o</STRONG>   <STRONG>ncurses</STRONG>  re-fetches  the value of the environment variables so that
+           it is still the environment variables which set the screen size.
+
+       The <STRONG>use_env</STRONG> and <STRONG>use_tioctl</STRONG> routines combine as summarized here:

+           <STRONG>use_env</STRONG>   <STRONG>use_tioctl</STRONG>   <STRONG>Summary</STRONG>
+           ----------------------------------------------------------------
+           TRUE      FALSE        This is the default  behavior.   <STRONG>ncurses</STRONG>

+                                  to determine size.
+
+
+</PRE><H3><a name="h3-putwin_getwin">putwin/getwin</a></H3><PRE>
+       The  <STRONG>putwin</STRONG> routine writes all data associated with window (or pad) <EM>win</EM>
+       into the file to which <EM>filep</EM> points.  This information can be later re-
+       trieved using the <STRONG>getwin</STRONG> function.
+
+       The  <STRONG>getwin</STRONG>  routine  reads  window  related data stored in the file by
+       <STRONG>putwin</STRONG>.  The routine then creates and initializes a  new  window  using
+       that  data.   It  returns a pointer to the new window.  There are a few
+       caveats:
+
+       <STRONG>o</STRONG>   the data written is a copy of the <STRONG>WINDOW</STRONG> structure, and its associ-
+           ated  character cells.  The format differs between the wide-charac-
+           ter (<STRONG>ncursesw</STRONG>) and non-wide (<STRONG>ncurses</STRONG>) libraries.  You can  transfer
+           data between the two, however.
+
+       <STRONG>o</STRONG>   the  retrieved  window  is always created as a top-level window (or
+           pad), rather than a subwindow.
+
+       <STRONG>o</STRONG>   the window's character cells contain the color pair <EM>value</EM>, but  not
+           the  actual  color  <EM>numbers</EM>.   If cells in the retrieved window use
+           color pairs which have not been created in  the  application  using
+           <STRONG>init_pair</STRONG>, they will not be colored when the window is refreshed.
+
+
+</PRE><H3><a name="h3-delay_output">delay_output</a></H3><PRE>
+       The  <STRONG>delay_output</STRONG>  routine  inserts  an <EM>ms</EM> millisecond pause in output.
+       This routine should not be used extensively because padding  characters
+       are  used  rather  than a CPU pause.  If no padding character is speci-
+       fied, this uses <STRONG>napms</STRONG> to perform the delay.
+
+
+</PRE><H3><a name="h3-flushinp">flushinp</a></H3><PRE>
+       The <STRONG>flushinp</STRONG> routine throws away any typeahead that has been  typed  by

+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       Except  for  <STRONG>flushinp</STRONG>,  routines that return an integer return <STRONG>ERR</STRONG> upon
+       failure and <STRONG>OK</STRONG> (SVr4 specifies only "an integer value other than  <STRONG>ERR</STRONG>")
+       upon successful completion.
+
+       Routines that return pointers return <STRONG>NULL</STRONG> on error.
+
+       X/Open does not define any error conditions.  In this implementation
+
+          <STRONG>flushinp</STRONG>
+               returns an error if the terminal was not initialized.
+
+          <STRONG>putwin</STRONG>
+               returns  an  error if the associated <STRONG>fwrite</STRONG> calls return an er-
+               ror.

+       The SVr4 documentation describes the  action  of  <STRONG>filter</STRONG>  only  in  the
+       vaguest  terms.   The  description  here is adapted from the XSI Curses
+       standard (which erroneously fails to describe the disabling of <STRONG>cuu</STRONG>).
+
+
+</PRE><H3><a name="h3-keyname">keyname</a></H3><PRE>
+       The <STRONG>keyname</STRONG> function may return the names of user-defined string  capa-
+       bilities  which  are defined in the terminfo entry via the <STRONG>-x</STRONG> option of
+       <STRONG>tic</STRONG>.  This implementation automatically assigns at run-time keycodes to
+       user-defined  strings  which  begin  with  "k".   The keycodes start at
+       KEY_MAX, but are not guaranteed to be the same value for different runs
+       because  user-defined  codes  are merged from all terminal descriptions
+       which have been loaded.  The <STRONG><A HREF="curs_extend.3x.html">use_extended_names(3x)</A></STRONG>  function  controls
+       whether  this  data  is loaded when the terminal description is read by
+       the library.
+
+
+</PRE><H3><a name="h3-nofilter_use_tioctl">nofilter/use_tioctl</a></H3><PRE>
+       The <STRONG>nofilter</STRONG> and <STRONG>use_tioctl</STRONG> routines are  specific  to  <STRONG>ncurses</STRONG>.   They
+       were  not  supported on Version 7, BSD or System V implementations.  It
+       is recommended that any code depending on <STRONG>ncurses</STRONG> extensions be  condi-
+       tioned using NCURSES_VERSION.
+
+
+</PRE><H3><a name="h3-putwin_getwin-file-format">putwin/getwin file-format</a></H3><PRE>
+       The <STRONG>putwin</STRONG> and <STRONG>getwin</STRONG> functions have several issues with portability:
+
+       <STRONG>o</STRONG>   The  files  written  and read by these functions use an implementa-
+           tion-specific format.  Although the format is an obvious target for
+           standardization, it has been overlooked.
+
+           Interestingly  enough,  according to the copyright dates in Solaris
+           source, the functions (along with <STRONG>scr_init</STRONG>, etc.)  originated  with
+           the University of California, Berkeley (in 1982) and were later (in
+           1988) incorporated into SVr4.  Oddly, there are no  such  functions
+           in the 4.3BSD curses sources.
+
+       <STRONG>o</STRONG>   Most implementations simply dump the binary <STRONG>WINDOW</STRONG> structure to the
+           file.  These include SVr4 curses, NetBSD and PDCurses, as  well  as
+           older <STRONG>ncurses</STRONG> versions.  This implementation (as well as the X/Open
+           variant of Solaris curses, dated 1995) uses textual dumps.
+
+           The implementations which  use  binary  dumps  use  block-I/O  (the
+           <STRONG>fwrite</STRONG>  and  <STRONG>fread</STRONG>  functions).   Those  that use textual dumps use
+           buffered-I/O.  A few applications may happen to write extra data in
+           the  file  using these functions.  Doing that can run into problems
+           mixing block- and buffered-I/O.  This  implementation  reduces  the
+           problem  on writes by flushing the output.  However, reading from a
+           file written using mixed schemes may not be successful.
+
+
+</PRE><H3><a name="h3-unctrl_wunctrl">unctrl/wunctrl</a></H3><PRE>
+       The XSI Curses standard, Issue 4 describes these functions.  It  states
+       that <STRONG>unctrl</STRONG> and <STRONG>wunctrl</STRONG> will return a null pointer if unsuccessful, but
+       does not define any error conditions.  This implementation  checks  for
+       three cases:
+
+       <STRONG>o</STRONG>   the  parameter  is  a  7-bit  US-ASCII code.  This is the case that
+           X/Open Curses documented.
+
+       <STRONG>o</STRONG>   the parameter is in the range 128-159, i.e., a C1 control code.  If
+           <STRONG><A HREF="legacy_coding.3x.html">use_legacy_coding(3x)</A></STRONG>  has  been  called with a <STRONG>2</STRONG> parameter, <STRONG>unctrl</STRONG>
+           returns the parameter, i.e., a one-character string with the param-
+           eter  as  the  first  character.  Otherwise, it returns "~@", "~A",
+           etc., analogous to "^@", "^A", C0 controls.
+
+           X/Open Curses does not document whether <STRONG>unctrl</STRONG> can be called before
+           initializing curses.  This implementation permits that, and returns
+           the "~@", etc., values in that case.
+
+       <STRONG>o</STRONG>   parameter values outside the 0 to 255 range.  <STRONG>unctrl</STRONG> returns a null
+           pointer.
+
+       The strings returned by <STRONG>unctrl</STRONG> in this implementation are determined at
+       compile time, showing C1 controls from the upper-128 codes with  a  "~"
+       prefix  rather  than "^".  Other implementations have different conven-
+       tions.  For example, they may show both sets of control characters with
+       "^", and strip the parameter to 7 bits.  Or they may ignore C1 controls
+       and treat all of the upper-128 codes as printable.  This implementation
+       uses  8  bits  but  does  not modify the string to reflect locale.  The
+       <STRONG><A HREF="legacy_coding.3x.html">use_legacy_coding(3x)</A></STRONG> function allows the caller to change  the  output

+       Likewise,  the <STRONG><A HREF="curs_inopts.3x.html">meta(3x)</A></STRONG> function allows the caller to change the output
+       of <STRONG>keyname</STRONG>, i.e., it determines whether to  use  the  "M-"  prefix  for
+       "meta"  keys  (codes  in  the  range 128 to 255).  Both <STRONG>use_legacy_cod-</STRONG>

+       Curses  does  not  document  the  treatment  of codes 128 to 159.  When
+       treating them as "meta" keys (or if <STRONG>keyname</STRONG> is called before initializ-
+       ing curses), this implementation returns strings "M-^@", "M-^A", etc.
+
+       X/Open Curses documents <STRONG>unctrl</STRONG> as declared in <STRONG>&lt;unctrl.h&gt;</STRONG>, which <STRONG>ncurses</STRONG>
+       does.  However, <STRONG>ncurses</STRONG>' <STRONG>&lt;curses.h&gt;</STRONG> includes <STRONG>&lt;unctrl.h&gt;</STRONG>,  matching  the

+       <STRONG>TABSIZE</STRONG>  is  a feature of SVr4 curses which is not documented by X/Open
+       curses.
+
+       <STRONG>o</STRONG>   In SVr4 curses, <STRONG>TABSIZE</STRONG> is initially set from the terminal descrip-
+           tion's  <STRONG>init_tabs</STRONG> capability.  After that, it can be altered by the
+           applications using SVr4 curses.
+
+           SVr4 curses uses the current value of <STRONG>TABSIZE</STRONG> to compute the  posi-
+           tion  of  tabstops  for  updating both the virtual screen with <STRONG>add-</STRONG>
+           <STRONG><A HREF="addch.3x.html">ch(3x)</A></STRONG> as well as the physical screen with <STRONG><A HREF="curs_terminfo.3x.html">mvcur(3x)</A></STRONG>.
+
+       <STRONG>o</STRONG>   This implementation uses the current value of <STRONG>TABSIZE</STRONG> only for  up-
+           dating  the  virtual screen.  It uses the terminal description's <STRONG>it</STRONG>
+           (<STRONG>init_tabs</STRONG>) capability for computing hardware tabs (i.e., tab stops
+           on the physical screen).
+
+       <STRONG>o</STRONG>   Other  implementations  differ.  For instance, NetBSD curses allows
+           <STRONG>TABSIZE</STRONG> to be set through an environment variable.  This  implemen-
+           tation does not.
+
+           NetBSD curses does not support hardware tabs; it uses the <STRONG>init_tabs</STRONG>
+           capability and the <STRONG>TABSIZE</STRONG> variable only for updating  the  virtual
+           screen.
+
+       <STRONG>ESCDELAY</STRONG> is an extension in AIX curses:
+
+       <STRONG>o</STRONG>   In AIX, the units for <STRONG>ESCDELAY</STRONG> are <EM>fifths</EM> of a millisecond.
+
+       <STRONG>o</STRONG>   The default value for AIX's <STRONG>ESCDELAY</STRONG> is 0.1 seconds.
+
+       <STRONG>o</STRONG>   AIX  also enforces a limit of 10,000 seconds for <STRONG>ESCDELAY</STRONG>; this im-
+           plementation currently has no upper limit.
+
+       This implementation has long used <STRONG>ESCDELAY</STRONG> with units of  milliseconds,
+       making  it  impossible to be completely compatible with AIX.  Likewise,
+       most users have either decided to override the value, or rely upon  its
+       default value.

+       Calling <STRONG>newwin</STRONG> creates and returns a pointer to a new window  with  the
+       given  number  of lines and columns.  The upper left-hand corner of the

+              line <EM>begin</EM>_<EM>y</EM>,
+              column <EM>begin</EM>_<EM>x</EM>

+
+       A new full-screen window is created by calling <STRONG>newwin(0,0,0,0)</STRONG>.
+
+       Regardless of the function  used  for  creating  a  new  window  (e.g.,
+       <STRONG>newwin</STRONG>, <STRONG>subwin</STRONG>, <STRONG>derwin</STRONG>, <STRONG>newpad</STRONG>), rather than a duplicate (with <STRONG>dupwin</STRONG>),
+       all of the window modes are initialized to the default  values.   These
+       functions set window modes after a window is created:
+

+       Calling <STRONG>delwin</STRONG> deletes the named window, freeing all memory  associated
+       with  it  (it does not actually erase the window's screen image).  Sub-
+       windows must be deleted before the main window can be deleted.

+       Calling <STRONG>mvwin</STRONG> moves the window so that the upper left-hand corner is at
+       position  (<EM>x</EM>,  <EM>y</EM>).   If  the  move would cause the window to be off the
+       screen, it is an error and the window is not moved.  Moving  subwindows
+       is allowed, but should be avoided.
+
+
+</PRE><H3><a name="h3-subwin">subwin</a></H3><PRE>
+       Calling  <STRONG>subwin</STRONG>  creates and returns a pointer to a new window with the
+       given number of lines, <EM>nlines</EM>, and columns, <EM>ncols</EM>.  The  window  is  at
+       position (<EM>begin</EM>_<EM>y</EM>, <EM>begin</EM>_<EM>x</EM>) on the screen.  The subwindow shares memory
+       with the window <EM>orig</EM>, so that changes made to one  window  will  affect
+       both  windows.  When using this routine, it is necessary to call <STRONG>touch-</STRONG>
+       <STRONG>win</STRONG> or <STRONG>touchline</STRONG> on <EM>orig</EM> before calling <STRONG>wrefresh</STRONG> on the subwindow.
+
+
+</PRE><H3><a name="h3-derwin">derwin</a></H3><PRE>
+       Calling <STRONG>derwin</STRONG> is the same as calling <STRONG>subwin,</STRONG> except that  <EM>begin</EM>_<EM>y</EM>  and
+       <EM>begin</EM>_<EM>x</EM>  are  relative to the origin of the window <EM>orig</EM> rather than the
+       screen.  There is no difference between the subwindows and the  derived
+       windows.
+
+       Calling  <STRONG>mvderwin</STRONG> moves a derived window (or subwindow) inside its par-
+       ent window.  The screen-relative  parameters  of  the  window  are  not
+       changed.  This routine is used to display different parts of the parent
+       window at the same physical position on the screen.
+
+
+</PRE><H3><a name="h3-dupwin">dupwin</a></H3><PRE>

+       Calling <STRONG>wsyncup</STRONG> touches all locations in  ancestors  of  <EM>win</EM>  that  are
+       changed  in  <EM>win</EM>.   If  <STRONG>syncok</STRONG> is called with second argument <STRONG>TRUE</STRONG> then
+       <STRONG>wsyncup</STRONG> is called automatically whenever there is a change in the  win-
+       dow.
+
+
+</PRE><H3><a name="h3-wsyncdown">wsyncdown</a></H3><PRE>
+       The  <STRONG>wsyncdown</STRONG>  routine  touches  each  location  in  <EM>win</EM> that has been
+       touched in any of its ancestor windows.  This routine is called by <STRONG>wre-</STRONG>
+       <STRONG>fresh</STRONG>, so it should almost never be necessary to call it manually.
+
+
+</PRE><H3><a name="h3-wcursyncup">wcursyncup</a></H3><PRE>
+       The  routine  <STRONG>wcursyncup</STRONG> updates the current cursor position of all the
+       ancestors of the window to reflect the current cursor position  of  the
+       window.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       Routines that return an integer return the integer <STRONG>ERR</STRONG> upon failure and
+       <STRONG>OK</STRONG> (SVr4 only specifies "an integer value other than  <STRONG>ERR</STRONG>")  upon  suc-
+       cessful completion.
+
+       Routines that return pointers return <STRONG>NULL</STRONG> on error.
+
+       X/Open defines no error conditions.  In this implementation
+
+       <STRONG>delwin</STRONG>
+            returns  an  error if the window pointer is null, or if the window
+            is the parent of another window.
+
+       <STRONG>derwin</STRONG>
+            returns an error if the parent window pointer is null, or  if  any
+            of  its  ordinates  or dimensions is negative, or if the resulting
+            window does not fit inside the parent window.
+
+       <STRONG>dupwin</STRONG>
+            returns an error if the window pointer is null.
+
+            This implementation also maintains a list of windows,  and  checks
+            that  the pointer passed to <STRONG>delwin</STRONG> is one that it created, return-
+            ing an error if it was not..
+
+       <STRONG>mvderwin</STRONG>
+            returns an error if the window pointer is null, or if some part of
+            the window would be placed off-screen.
+
+       <STRONG>mvwin</STRONG>
+            returns  an  error if the window pointer is null, or if the window
+            is really a pad, or if some part of the  window  would  be  placed
+            off-screen.
+
+       <STRONG>newwin</STRONG>
+            will  fail if either of its beginning ordinates is negative, or if
+            either the number of lines or columns is negative.
+
+       <STRONG>syncok</STRONG>
+            returns an error if the window pointer is null.
+
+       <STRONG>subwin</STRONG>
+            returns an error if the parent window pointer is null, or  if  any
+            of  its  ordinates  or dimensions is negative, or if the resulting
+            window does not fit inside the parent window.
+
+       The functions which return a window pointer may also fail if  there  is
+       insufficient  memory  for  its data structures.  Any of these functions
+       will fail if the screen has not been initialized, i.e., with <STRONG>initscr</STRONG> or
+       <STRONG>newterm</STRONG>.

+       If  many small changes are made to the window, the <STRONG>wsyncup</STRONG> option could
+       degrade performance.

+       The subwindow functions (<STRONG>subwin</STRONG>, <STRONG>derwin</STRONG>, <STRONG>mvderwin</STRONG>, <STRONG>wsyncup</STRONG>,  <STRONG>wsyncdown</STRONG>,
+       <STRONG>wcursyncup</STRONG>,  <STRONG>syncok</STRONG>)  are flaky, incompletely implemented, and not well
+       tested.
+
+       The System V curses documentation is very unclear  about  what  <STRONG>wsyncup</STRONG>
+       and  <STRONG>wsyncdown</STRONG>  actually do.  It seems to imply that they are only sup-
+       posed to touch exactly  those  lines  that  are  affected  by  ancestor
+       changes.  The language here, and the behavior of the <STRONG>curses</STRONG> implementa-
+       tion, is patterned on the XPG4 curses standard.  The weaker  XPG4  spec
+       may result in slower updates.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       The XSI Curses standard, Issue 4 describes these functions.
+
+       X/Open Curses states regarding <STRONG>delwin</STRONG>:
+
+       <STRONG>o</STRONG>   It must delete subwindows before deleting their parent.
+
+       <STRONG>o</STRONG>   If  <STRONG>delwin</STRONG>  is asked to delete a parent window, it can only succeed
+           if the curses library keeps a list of the subwindows.  SVr4  curses
+           kept  a  count  of the number of subwindows rather than a list.  It
+           simply returned <STRONG>ERR</STRONG> when asked  to  delete  a  subwindow.   Solaris
+           X/Open curses does not even make that check, and will delete a par-
+           ent window which still has subwindows.
+
+       <STRONG>o</STRONG>   Since release 4.0 (1996), ncurses maintains a list of  windows  for
+           each  screen,  to ensure that a window has no subwindows before al-
+           lowing deletion.
+
+       <STRONG>o</STRONG>   NetBSD copied this feature of ncurses in 2003.
+           PDCurses follows the scheme used in Solaris X/Open curses.

+       The  <STRONG>use_default_colors</STRONG>   and   <STRONG>assume_default_colors</STRONG>   functions   are
+       extensions  to  the  curses library.  They are used with terminals that
+       support ISO 6429 color,  or  equivalent.   These  terminals  allow  the
+       application  to reset color to an unspecified default value (e.g., with
+       SGR 39 or SGR 49).
+
+       Applications that paint a colored background over the whole  screen  do
+       not  take  advantage  of  SGR  39  and  SGR  49.  Some applications are
+       designed to work with the default background,  using  colors  only  for
+       text.  For example, there are several implementations of the <STRONG>ls</STRONG> program
+       which use colors to denote different file types or permissions.   These
+       "color  ls"  programs  do  not necessarily modify the background color,
+       typically  using  only  the  <STRONG>setaf</STRONG>  terminfo  capability  to  set   the
+       foreground color.  Full-screen applications that use default colors can
+       achieve similar visual effects.
+
+       The first function, <STRONG>use_default_colors</STRONG>  tells  the  curses  library  to
+       assign  terminal  default  foreground/background colors to color number
+       -1.  So init_pair(x,COLOR_RED,-1) will initialize  pair  x  as  red  on
+       default  background and init_pair(x,-1,COLOR_BLUE) will initialize pair
+       x as default foreground on blue.
+
+       The other, <STRONG>assume_default_colors</STRONG> is  a  refinement  which  tells  which
+       colors  to  paint for color pair 0.  This function recognizes a special
+       color number -1, which denotes the default terminal color.
+
+       The following are equivalent:
+              <EM>use</EM><STRONG>_</STRONG><EM>default</EM><STRONG>_</STRONG><EM>colors();</EM>

+
+       These are ncurses extensions.  For other curses implementations,  color
+       number  -1  does  not  mean  anything,  just  as  for  ncurses before a
+       successful call of <STRONG>use_default_colors</STRONG> or <STRONG>assume_default_colors</STRONG>.
+
+       Other curses implementations do not  allow  an  application  to  modify
+       color  pair  0.  They assume that the background is COLOR_BLACK, but do
+       not ensure that the color pair 0 is painted to  match  the  assumption.
+       If   your   application  does  not  use  either  <STRONG>use_default_colors</STRONG>  or
+       <STRONG>assume_default_colors</STRONG> ncurses will paint a white foreground (text) with
+       black background for color pair 0.

+       These  functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.
+       They will fail if either the terminal does not support the <STRONG>orig_pair</STRONG> or
+       <STRONG>orig_colors</STRONG>  capability.   If  the  <STRONG>initialize_pair</STRONG>  capability  is not
+       found, this causes an error as well.

+       Associated with this extension, the <STRONG>init_pair</STRONG> function accepts negative
+       arguments to specify default foreground or background colors.
+
+       The  <STRONG>use_default_colors</STRONG>  function  was added to support <STRONG>ded</STRONG>.  This is a
+       full-screen application which uses curses to manage only  part  of  the
+       screen.  The bottom portion of the screen, which is of adjustable size,
+       is left uncolored to display the results from shell commands.  The  top
+       portion  of  the screen colors filenames using a scheme like the "color
+       ls" programs.  Attempting to manage the background color of the  screen
+       for this application would give unsatisfactory results for a variety of
+       reasons.  This extension was devised after noting that color xterm (and
+       similar   programs)   provides   a  background  color  which  does  not
+       necessarily correspond to any of the  ANSI  colors.   While  a  special
+       terminfo  entry  could  be  constructed using nine colors, there was no
+       mechanism provided within curses to account for the  related  <STRONG>orig_pair</STRONG>
+       and <STRONG>back_color_erase</STRONG> capabilities.
+
+       The  <STRONG>assume_default_colors</STRONG>  function  was  added  to  solve a different
+       problem: support for applications which would use environment variables
+       and  other  configuration  to  bypass  curses' notion of the terminal's
+       default colors, setting specific values.

+       This  is an extension to the curses library.  It permits an application

+       the ncurses library will interpret them just as it would the predefined
+       codes in the terminfo database.
+
+       If the given string is null, any existing definition for the keycode is
+       removed.   Similarly,  if  the  given  keycode is negative or zero, any
+       existing string for the given definition is removed.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>

+       The <STRONG>form</STRONG> library provides terminal-independent facilities for composing
+       form screens on character-cell terminals.  The library includes:  field
+       routines, which create and modify form fields; and form routines, which
+       group fields into forms,  display  forms  on  the  screen,  and  handle
+       interaction with the user.
+
+       The  <STRONG>form</STRONG>  library uses the <STRONG>curses</STRONG> libraries.  To use the <STRONG>form</STRONG> library,
+       link with the options <STRONG>-lform</STRONG> <STRONG>-lcurses</STRONG>.
+
+       Your program should set up the locale, e.g.,
+
+            <STRONG>setlocale(LC_ALL,</STRONG> <STRONG>"");</STRONG>
+
+       so that input/output processing will work.
+
+       A curses initialization routine such as <STRONG>initscr</STRONG> must be  called  before

+       Once a form has been posted (displayed), you should funnel input events
+       to it through <STRONG>form_driver</STRONG>.  This routine has three major input cases:
+
+       <STRONG>o</STRONG>   The input is a form navigation request.  Navigation  request  codes
+           are constants defined in <STRONG>&lt;form.h&gt;</STRONG>, which are distinct from the key-
+           and character codes returned by <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG>.
+
+       <STRONG>o</STRONG>   The input is a printable character.   Printable  characters  (which
+           must  be  positive,  less  than  256)  are checked according to the
+           program's locale settings.
+
+       <STRONG>o</STRONG>   The input is the KEY_MOUSE special key  associated  with  an  mouse
+           event.
+
+

+       This  extension  simplifies  the  use  of  the forms library using wide

+       character returned by <STRONG><A HREF="curs_get_wch.3x.html">get_wch(3x)</A></STRONG>.  The type must be passed as well, to
+       enable the library  to  determine  whether  the  parameter  is  a  wide

+

+       The  form  library  makes  updates  to  the window associated with form
+       fields rather than directly to the field buffers.
+
+       The form driver provides low-level control over  updates  to  the  form
+       fields.   The  form driver also provides for validating modified fields
+       to ensure that the contents meet whatever  constraints  an  application
+       may attach using <STRONG>set_field_type</STRONG>.
+
+       You  can  validate  a  field  without  making  any  changes to it using
+       <STRONG>REQ_VALIDATION</STRONG>.  The form driver also validates a field in these cases:
+
+       <STRONG>o</STRONG>   a call to <STRONG>set_current_field</STRONG> attempts to move to a different field.
+
+       <STRONG>o</STRONG>   a call to <STRONG>set_current_page</STRONG> attempts to move to a different page  of
+           the form.
+
+       <STRONG>o</STRONG>   a request attempts to move to a different field.
+
+       <STRONG>o</STRONG>   a request attempts to move to a different page of the form.
+
+       In each case, the move fails if the field is invalid.
+
+       If  the  modified  field  is valid, the form driver copies the modified
+       data from the window associated with the field to the field buffer.
+
+
+</PRE><H3><a name="h3-Mouse-handling">Mouse handling</a></H3><PRE>
+       If the second argument is the KEY_MOUSE  special  key,  the  associated
+       mouse  event  is translated into one of the above pre-defined requests.
+       Currently only clicks in the user window (e.g., inside the form display
+       area or the decoration window) are handled.
+
+       If you click above the display region of the form:
+
+          a REQ_PREV_FIELD is generated for a single click,
+
+          a REQ_PREV_PAGE is generated for a double-click and
+
+          a REQ_FIRST_FIELD is generated for a triple-click.
+
+       If you click below the display region of the form:
+
+          a REQ_NEXT_FIELD is generated for a single click,
+
+          a REQ_NEXT_PAGE is generated for a double-click and
+
+          a REQ_LAST_FIELD is generated for a triple-click.
+
+       If you click at an field inside the display area of the form:
+
+          <STRONG>o</STRONG>   the form cursor is positioned to that field.
+
+          <STRONG>o</STRONG>   If  you  double-click  a field, the form cursor is positioned to
+              that field and <STRONG>E_UNKNOWN_COMMAND</STRONG> is returned.  This return value
+              makes sense, because a double click usually means that an field-
+              specific action should be returned.  It is exactly  the  purpose
+              of  this  return  value  to  signal that an application specific
+              command should be executed.
+
+          <STRONG>o</STRONG>   If a translation into a request was  done,  <STRONG>form_driver</STRONG>  returns
+              the result of this request.
+
+       If  you clicked outside the user window or the mouse event could not be
+       translated into a form request an <STRONG>E_REQUEST_DENIED</STRONG> is returned.
+
+
+</PRE><H3><a name="h3-Application-defined-commands">Application-defined commands</a></H3><PRE>
+       If the second argument is neither printable nor one of the  above  pre-
+       defined form requests, the driver assumes it is an application-specific
+       command and returns  <STRONG>E_UNKNOWN_COMMAND</STRONG>.   Application-defined  commands
+       should  be  defined relative to <STRONG>MAX_COMMAND</STRONG>, the maximum value of these
+       pre-defined requests.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       <STRONG>form_driver</STRONG> returns one of the following error codes:
+
+       <STRONG>E_OK</STRONG> The routine succeeded.
+
+       <STRONG>E_BAD_ARGUMENT</STRONG>
+            Routine detected an incorrect or out-of-range argument.
+
+       <STRONG>E_BAD_STATE</STRONG>
+            Routine was called from an initialization or termination function.

+          <STRONG>o</STRONG>   Buffer 0 is the displayed value of the field.

+              the  <STRONG>nbuf</STRONG>  argument  of  (see  <STRONG><A HREF="form_field_new.3x.html">form_field_new(3x)</A></STRONG>)  but  are not
+              manipulated by the forms library.
+
+       The function <STRONG>field_buffer</STRONG> returns a pointer  to  the  contents  of  the
+       given numbered buffer:
+
+          <STRONG>o</STRONG>   The  buffer contents always have the same length, and are padded
+              with trailing spaces as needed to  ensure  this  length  is  the
+              same.
+
+          <STRONG>o</STRONG>   The  buffer  may contain leading spaces, depending on how it was
+              set.
+
+          <STRONG>o</STRONG>   The buffer contents are set with <STRONG>set_field_buffer</STRONG>, or as a  side
+              effect of any editing operations on the corresponding field.
+
+          <STRONG>o</STRONG>   Editing  operations  are  based on the <EM>window</EM> which displays the
+              field, rather than a <EM>string</EM>.  The window contains only printable
+              characters,  and  is  filled  with  blanks.  If you want the raw
+              data, you must write your own routine that copies the value  out
+              of the buffer and removes the leading and trailing spaces.
+
+          <STRONG>o</STRONG>   Because  editing  operations change the content of the buffer to
+              correspond to the window, you should not rely on  using  buffers
+              for long-term storage of form data.
+
+       The function <STRONG>set_field_status</STRONG> sets the associated status flag of <EM>field</EM>;
+       <STRONG>field_status</STRONG> gets the current value.  The  status  flag  is  set  to  a
+       nonzero value whenever the field changes.
+
+       The  function  <STRONG>set_max_field</STRONG> sets the maximum size for a dynamic field.

+       The function <STRONG>new_field</STRONG> allocates a new field and  initializes  it  from
+       the  parameters  given: height, width, row of upper-left corner, column
+       of upper-left corner, number off-screen rows, and number of  additional
+       working buffers.
+
+       The  function  <STRONG>dup_field</STRONG>  duplicates  a  field at a new location.  Most
+       attributes (including current contents, size, validation  type,  buffer
+       count,  growth  threshold,  justification,  foreground, background, pad
+       character, options, and user pointer) are copied.  Field status and the
+       field page bit are not copied.
+
+       The  function  <STRONG>link_field</STRONG> acts like <STRONG>dup_field</STRONG>, but the new field shares
+       buffers with its parent.  Attribute data is separate.
+
+       The function <STRONG>free_field</STRONG> de-allocates storage associated with a field.
+

+       The functions <STRONG>new_field</STRONG>, <STRONG>dup_field</STRONG>, <STRONG>link_field</STRONG> return  <STRONG>NULL</STRONG>  on  error.
+       They set <STRONG>errno</STRONG> according to their success:
+
+       <STRONG>E_OK</STRONG> The routine succeeded.
+
+       <STRONG>E_BAD_ARGUMENT</STRONG>
+            Routine detected an incorrect or out-of-range argument.
+
+       <STRONG>E_SYSTEM_ERROR</STRONG>
+            System error occurred, e.g., malloc failure.
+
+       The function <STRONG>free_field</STRONG> returns one of the following:
+
+       <STRONG>E_OK</STRONG> The routine succeeded.
+
+       <STRONG>E_BAD_ARGUMENT</STRONG>
+            Routine detected an incorrect or out-of-range argument.

+       The function <STRONG>set_field_opts</STRONG> sets all  the  given  field's  option  bits
+       (field option bits may be logically-OR'ed together).
+
+       The  function  <STRONG>field_opts_on</STRONG> turns on the given option bits, and leaves
+       others alone.
+
+       The function <STRONG>field_opts_off</STRONG> turns off the given option bits, and leaves
+       others alone.
+
+       The function <STRONG>field_opts</STRONG> returns the field's current option bits.
+
+       The following standard options are defined (all are on by default):
+
+       O_ACTIVE
+            The  field  is  visited during processing.  If this option is off,
+            the field will not be reachable by navigation keys.  Please notice
+            that an invisible field appears to be inactive also.
+
+       O_AUTOSKIP
+            Skip to the next field when this one fills.
+
+       O_BLANK
+            The  field is cleared whenever a character is entered at the first
+            position.
+
+       O_EDIT
+            The field can be edited.
+
+       O_NULLOK
+            Allow a blank field.
+
+       O_PASSOK
+            Validate field only if modified by user.
+
+       O_PUBLIC
+            The field contents are displayed as data is entered.
+
+       O_STATIC
+            Field buffers are fixed  to  field's  original  size.   Turn  this
+            option off to create a dynamic field.
+
+       O_VISIBLE
+            The  field  is  displayed.   If this option is off, display of the
+            field is suppressed.
+
+       O_WRAP
+            Words that do not fit on a line are  wrapped  to  the  next  line.
+            Words are blank-separated.
+
+       These extension options are defined (extensions are off by default):
+
+       O_DYNAMIC_JUSTIFY
+            Permit dynamic fields to be justified, like static fields.
+
+       O_NO_LEFT_STRIP
+            Preserve leading whitespace in the field buffer, which is normally
+            discarded.
+
+       O_EDGE_INSERT_STAY
+            When  inserting  into  a  field  up  to  the  boundary   position,
+            optionally   delay  the  scrolling,  so  that  the  last  inserted
+            character remains visible, but advance the cursor to  reflect  the
+            insertion.   This  allows the form library to display the inserted
+            character in one-character fields as well as allowing the  library
+            to maintain consistent state.
+
+       O_INPUT_FIELD
+            The <STRONG>set_max_field</STRONG> function checks for this extension, which allows
+            a dynamic field to shrink if the new limit  is  smaller  than  the
+            current field size.
+

+       Returns a pointer to the <EM>field</EM> <EM>type</EM> associated  with  the  form  field,

+
+
+</PRE><H3><a name="h3-set_field_type">set_field_type</a></H3><PRE>
+       The  function  <STRONG>set_field_type</STRONG> associates a field type with a given form
+       field.  This is the type checked by validation functions.   Most  field
+       types  are  configurable,  via arguments which the caller provides when
+       calling <STRONG>set_field_type</STRONG>.
+
+       Several field types are predefined by the form library.
+
+
+</PRE><H3><a name="h3-Predefined-types">Predefined types</a></H3><PRE>
+       It is possible to set up new  programmer-defined  field  types.   Field
+       types  are implemented via the <STRONG>FIELDTYPE</STRONG> data structure, which contains
+       several pointers to functions.
+
+       See the <STRONG><A HREF="form_fieldtype.3x.html">form_fieldtype(3x)</A></STRONG> manual page, which describes functions which
+       can be used to construct a field-type dynamically.
+
+       The predefined types are as follows:
+
+       TYPE_ALNUM
+            Alphanumeric data.  Required parameter:
+
+            <STRONG>o</STRONG>   a third <STRONG>int</STRONG> argument, a minimum field width.
+
+       TYPE_ALPHA
+            Character data.  Required parameter:
+
+            <STRONG>o</STRONG>   a third <STRONG>int</STRONG> argument, a minimum field width.
+
+       TYPE_ENUM
+            Accept one of a specified set of strings.  Required parameters:
+
+            <STRONG>o</STRONG>   a third <STRONG>(char</STRONG> <STRONG>**)</STRONG> argument pointing to a string list;
+
+            <STRONG>o</STRONG>   a fourth <STRONG>int</STRONG> flag argument to enable case-sensitivity;
+
+            <STRONG>o</STRONG>   a  fifth  <STRONG>int</STRONG> flag argument specifying whether a partial match
+                must be a unique one.  If this flag is off, a  prefix  matches
+                the  first of any set of more than one list elements with that
+                prefix.
+
+            The library copies the string list, so you may  use  a  list  that
+            lives in automatic variables on the stack.
+
+       TYPE_INTEGER
+            Integer  data,  parsable  to  an  integer  by  <STRONG>atoi(3)</STRONG>.   Required
+            parameters:
+
+            <STRONG>o</STRONG>   a third <STRONG>int</STRONG> argument controlling the precision,
+
+            <STRONG>o</STRONG>   a fourth <STRONG>long</STRONG> argument constraining minimum value,
+
+            <STRONG>o</STRONG>   a fifth <STRONG>long</STRONG> constraining maximum value.  If the maximum value
+                is  less  than  or  equal  to  the minimum value, the range is
+                simply ignored.
+
+            On return, the field buffer is formatted according to  the  <STRONG>printf</STRONG>
+            format  specification  ".*ld",  where  the  "*" is replaced by the
+            precision argument.
+
+            For details of the precision handling see <STRONG>printf(3)</STRONG>.
+
+       TYPE_NUMERIC
+            Numeric  data  (may  have   a   decimal-point   part).    Required
+            parameters:
+
+            <STRONG>o</STRONG>   a third <STRONG>int</STRONG> argument controlling the precision,
+
+            <STRONG>o</STRONG>   a fourth <STRONG>double</STRONG> argument constraining minimum value,
+
+            <STRONG>o</STRONG>   and a fifth <STRONG>double</STRONG> constraining maximum value.  If your system
+                supports locales, the decimal point character must be the  one
+                specified  by  your locale.  If the maximum value is less than
+                or equal to the minimum value, the range is simply ignored.
+
+            On return, the field buffer is formatted according to  the  <STRONG>printf</STRONG>
+            format  specification  ".*f",  where  the  "*"  is replaced by the
+            precision argument.
+
+            For details of the precision handling see <STRONG>printf(3)</STRONG>.
+
+       TYPE_REGEXP
+            Regular expression data.  Required parameter:
+
+            <STRONG>o</STRONG>   a third argument, a regular expression <STRONG>(char</STRONG> <STRONG>*)</STRONG>  string.   The
+                data is valid if the regular expression matches it.
+
+            Regular expressions are in the format of <STRONG>regcomp</STRONG> and <STRONG>regexec</STRONG>.
+
+            The  regular  expression  must match the whole field.  If you have
+            for example, an eight character wide field, a  regular  expression
+            "^[0-9]*$"  always means that you have to fill all eight positions
+            with digits.  If you want to allow fewer digits, you may  use  for
+            example  "^[0-9]*  *$" which is good for trailing spaces (up to an
+            empty field), or "^ *[0-9]* *$" which  is  good  for  leading  and
+            trailing spaces around the digits.
+
+       TYPE_IPV4
+            An Internet Protocol Version 4 address.  Required parameter:
+
+            <STRONG>o</STRONG>   none
+
+            The  form  library  checks  whether or not the buffer has the form
+            <EM>a.b.c.d</EM>, where <EM>a</EM>, <EM>b</EM>, <EM>c</EM>, and <EM>d</EM> are numbers in the range 0  to  255.
+            Trailing  blanks in the buffer are ignored.  The address itself is
+            not validated.
+
+            This is an ncurses extension; this field type may not be available
+            in other curses implementations.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       The  functions  <STRONG>field_type</STRONG>  and  <STRONG>field_arg</STRONG>  return  <STRONG>NULL</STRONG> on error.  The

+       The  function  <STRONG>new_fieldtype</STRONG>  creates  a new field type usable for data
+       validation.  Its parameters are function pointers:
+
+       <EM>field</EM><STRONG>_</STRONG><EM>check</EM>
+            This function checks  the  validity  of  an  entered  data  string
+            whenever  the  user  attempts  to  leave  a  field.   It  has  two
+            arguments:
+
+            <STRONG>o</STRONG>   The  (FIELD  *)  argument  is  passed  in  so  the  validation
+                predicate   can  see  the  field's  buffer,  sizes  and  other
+                attributes.
+
+            <STRONG>o</STRONG>   The second argument  is  an  argument-block  structure,  about
+                which more below.
+
+       <EM>char</EM><STRONG>_</STRONG><EM>check</EM>
+            This function validates input characters as they are entered.  The
+            form library passes it the character to be checked and  a  pointer
+            to an argument-block structure.
+
+
+</PRE><H3><a name="h3-free_fieldtype">free_fieldtype</a></H3><PRE>
+       The  <STRONG>free_fieldtype</STRONG>  function  frees  the  space  allocated for a given
+       validation type by <STRONG>new_fieldtype</STRONG>.
+
+
+</PRE><H3><a name="h3-set_fieldtype_arg">set_fieldtype_arg</a></H3><PRE>
+       The  function  <STRONG>set_fieldtype_arg</STRONG>  associates  three  storage-management
+       functions with a field type:
+
+       <EM>make</EM><STRONG>_</STRONG><EM>arg</EM>
+            This  function  is  automatically applied to the list of arguments
+            you give <STRONG>set_field_type</STRONG> when attaching validation to a field.   It
+            stores  the  arguments in an allocated argument-block object which
+            is used when validating input.
+
+       <EM>copy</EM><STRONG>_</STRONG><EM>arg</EM>
+            This function may be used by applications to copy argument-blocks.
+
+       <EM>free</EM><STRONG>_</STRONG><EM>arg</EM>
+            Frees an argument-block structure.
+
+       You must supply the <EM>make</EM><STRONG>_</STRONG><EM>arg</EM> function.  The other two are optional: you
+       may  supply NULL for them.  In this case, the form library assumes that
+       <EM>make</EM><STRONG>_</STRONG><EM>arg</EM> does not allocate memory but simply loads the argument into  a
+       single scalar value.
+
+
+</PRE><H3><a name="h3-set_fieldtype_choice">set_fieldtype_choice</a></H3><PRE>
+       The  form  driver  requests  <STRONG>REQ_NEXT_CHOICE</STRONG> and <STRONG>REQ_PREV_CHOICE</STRONG> assume
+       that the possible values of a field form an ordered  set,  and  provide
+       the forms user with a way to move through the set.
+
+       The  <STRONG>set_fieldtype_choice</STRONG>  function  allows forms programmers to define
+       successor  and  predecessor  functions  for  the  field  type.    These
+       functions  take  the  field  pointer and an argument-block structure as
+       arguments.
+
+
+</PRE><H3><a name="h3-link_fieldtype">link_fieldtype</a></H3><PRE>
+       The function <STRONG>link_fieldtype</STRONG> creates a new field type from the two given
+       types.  They are connected by an logical 'OR'.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       The  pointer-valued  routines  return  NULL  on  error.  They set <STRONG>errno</STRONG>
+       according to their success:
+
+       <STRONG>E_OK</STRONG> The routine succeeded.
+
+       <STRONG>E_BAD_ARGUMENT</STRONG>
+            Routine detected an incorrect or out-of-range argument.
+
+       <STRONG>E_SYSTEM_ERROR</STRONG>
+            System error occurred, e.g., malloc failure.
+
+       The integer-valued routines return one of the following codes on error:
+
+       <STRONG>E_OK</STRONG> The routine succeeded.
+
+       <STRONG>E_BAD_ARGUMENT</STRONG>
+            Routine detected an incorrect or out-of-range argument.
+
+       <STRONG>E_CONNECTED</STRONG>
+            The field is already connected to a form.
+
+       <STRONG>E_CURRENT</STRONG>
+            The field is the current field.

+       Every  form  has an associated pair of <STRONG>curses</STRONG> windows.  The form window
+       displays any title and border associated  with  the  window;  the  form
+       subwindow  displays  the items of the form that are currently available
+       for selection.
+
+       The first four  functions  get  and  set  those  windows.   It  is  not
+       necessary to set either window; by default, the driver code uses <STRONG>stdscr</STRONG>
+       for both.
+
+       In the <STRONG>set_</STRONG> functions, window argument of <STRONG>NULL</STRONG> is treated as though  it
+       were <STRONG>stsdcr</STRONG>.  A form argument of <STRONG>NULL</STRONG> is treated as a request to change
+       the system default form window or subwindow.
+
+       The function <STRONG>scale_form</STRONG> returns  the  minimum  size  required  for  the
+       subwindow of <EM>form</EM>.

+       <STRONG>infocmp</STRONG>  can  be  used  to  compare  a binary <STRONG>terminfo</STRONG> entry with other
+       terminfo entries, rewrite a <STRONG>terminfo</STRONG> description to take  advantage  of
+       the  <STRONG>use=</STRONG>  terminfo field, or print out a <STRONG>terminfo</STRONG> description from the
+       binary file (<STRONG>term</STRONG>) in a variety of formats.  In all cases, the  boolean
+       fields  will be printed first, followed by the numeric fields, followed
+       by the string fields.
+
+
+</PRE><H3><a name="h3-Default-Options">Default Options</a></H3><PRE>
+       If no options are specified and zero or one  <EM>termnames</EM>  are  specified,
+       the <STRONG>-I</STRONG> option will be assumed.  If more than one <EM>termname</EM> is specified,
+       the <STRONG>-d</STRONG> option will be assumed.
+
+
+</PRE><H3><a name="h3-Comparison-Options-_-d_-_-c_-_-n_">Comparison Options [-d] [-c] [-n]</a></H3><PRE>
+       <STRONG>infocmp</STRONG>  compares  the  <STRONG>terminfo</STRONG>  description  of  the  first  terminal
+       <EM>termname</EM>  with  each  of  the descriptions given by the entries for the
+       other terminal's <EM>termnames</EM>.  If a capability is defined for only one of
+       the   terminals,  the  value  returned  depends  on  the  type  of  the
+       capability:
+
+       <STRONG>o</STRONG>   <STRONG>F</STRONG> for missing boolean variables
+
+       <STRONG>o</STRONG>   <STRONG>NULL</STRONG> for missing integer or string variables
+
+       Use the <STRONG>-q</STRONG> option to show the distinction between <EM>absent</EM> and  <EM>cancelled</EM>
+       capabilities.
+
+       These  options  produce a list which you can use to compare two or more
+       terminal descriptions:
+
+       <STRONG>-d</STRONG>   produces a list of each capability that is <EM>different</EM>  between  two
+            entries.   Each  item  in  the list shows ":" after the capability
+            name, followed by the capability values, separated by a comma.
+
+       <STRONG>-c</STRONG>   produces a list of each capability that is <EM>common</EM> between  two  or
+            more entries.  Missing capabilities are ignored.  Each item in the
+            list  shows  "="  after  the  capability  name,  followed  by  the
+            capability value.
+
+            The  <STRONG>-u</STRONG>  option  provides  a  related  output,  showing  the first
+            terminal description rewritten to use the  second  as  a  building
+            block via the "use=" clause.
+
+       <STRONG>-n</STRONG>   produces  a  list  of each capability that is in <EM>none</EM> of the given
+            entries.  Each item in the list shows "!"  before  the  capability
+            name.
+
+            Normally only the conventional capabilities are shown.  Use the <STRONG>-x</STRONG>
+            option to add the BSD-compatibility capabilities  (names  prefixed
+            with "OT").
+
+            If  no  <EM>termnames</EM> are given, <STRONG>infocmp</STRONG> uses the environment variable
+            <STRONG>TERM</STRONG> for each of the <EM>termnames</EM>.
+
+
+</PRE><H3><a name="h3-Source-Listing-Options-_-I_-_-L_-_-C_-_-r_">Source Listing Options [-I] [-L] [-C] [-r]</a></H3><PRE>
+       The <STRONG>-I</STRONG>, <STRONG>-L</STRONG>, and <STRONG>-C</STRONG> options will  produce  a  source  listing  for  each
+       terminal named.
+
+            <STRONG>-I</STRONG>   use the <STRONG>terminfo</STRONG> names
+            <STRONG>-L</STRONG>   use the long C variable name listed in &lt;<STRONG>term.h</STRONG>&gt;
+            <STRONG>-C</STRONG>   use the <STRONG>termcap</STRONG> names
+            <STRONG>-r</STRONG>   when using <STRONG>-C</STRONG>, put out all capabilities in <STRONG>termcap</STRONG> form
+            <STRONG>-K</STRONG>   modifies the <STRONG>-C</STRONG> option, improving BSD-compatibility.
+
+       If  no  <EM>termnames</EM> are given, the environment variable <STRONG>TERM</STRONG> will be used
+       for the terminal name.
+
+       The source produced by the <STRONG>-C</STRONG> option may be used directly as a  <STRONG>termcap</STRONG>
+       entry,  but not all parameterized strings can be changed to the <STRONG>termcap</STRONG>
+       format.  <STRONG>infocmp</STRONG> will attempt to  convert  most  of  the  parameterized
+       information,  and  anything not converted will be plainly marked in the
+       output and commented out.  These should be edited by hand.
+
+       For best results when converting to <STRONG>termcap</STRONG> format, you should use both
+       <STRONG>-C</STRONG>  and  <STRONG>-r</STRONG>.   Normally a termcap description is limited to 1023 bytes.
+       <STRONG>infocmp</STRONG> trims away less essential parts to make it  fit.   If  you  are
+       converting to one of the (rare) termcap implementations which accept an
+       unlimited size of termcap, you may want to add  the  <STRONG>-T</STRONG>  option.   More
+       often  however,  you  must  help  the  termcap implementation, and trim
+       excess whitespace (use the <STRONG>-0</STRONG> option for that).
+
+       All padding information for strings  will  be  collected  together  and
+       placed  at  the  beginning  of  the  string  where  <STRONG>termcap</STRONG> expects it.
+       Mandatory padding (padding information with a trailing "/") will become
+       optional.
+
+       All  <STRONG>termcap</STRONG>  variables  no longer supported by <STRONG>terminfo</STRONG>, but which are
+       derivable from other <STRONG>terminfo</STRONG>  variables,  will  be  output.   Not  all
+       <STRONG>terminfo</STRONG>  capabilities  will  be translated; only those variables which
+       were part of <STRONG>termcap</STRONG> will normally be output.  Specifying the <STRONG>-r</STRONG> option
+       will  take off this restriction, allowing all capabilities to be output
+       in <EM>termcap</EM> form.  Normally you would use both the <STRONG>-C</STRONG>  and  <STRONG>-r</STRONG>  options.
+       The  actual  format  used  incorporates  some  improvements for escaped
+       characters  from  terminfo  format.   For  a  stricter   BSD-compatible
+       translation, use the <STRONG>-K</STRONG> option rather than <STRONG>-C</STRONG>.
+
+       Note  that  because  padding  is  collected  to  the  beginning  of the
+       capability, not all capabilities are output.  Mandatory padding is  not
+       supported.   Because  <STRONG>termcap</STRONG>  strings  are  not as flexible, it is not
+       always possible  to  convert  a  <STRONG>terminfo</STRONG>  string  capability  into  an
+       equivalent <STRONG>termcap</STRONG> format.  A subsequent conversion of the <STRONG>termcap</STRONG> file
+       back into <STRONG>terminfo</STRONG> format will not necessarily reproduce  the  original
+       <STRONG>terminfo</STRONG> source.
+
+       Some  common  <STRONG>terminfo</STRONG>  parameter sequences, their <STRONG>termcap</STRONG> equivalents,
+       and some terminal types which commonly have such sequences, are:

+       The <STRONG>-u</STRONG> option produces a  <STRONG>terminfo</STRONG>  source  description  of  the  first
+       terminal  <EM>termname</EM>  which  is  relative  to the sum of the descriptions
+       given by the entries for the other terminals <EM>termnames</EM>.  It  does  this
+       by  analyzing  the differences between the first <EM>termname</EM> and the other
+       <EM>termnames</EM> and producing a description with <STRONG>use=</STRONG> fields  for  the  other
+       terminals.  In this manner, it is possible to retrofit generic terminfo
+       entries into a terminal's description.  Or, if  two  similar  terminals
+       exist, but were coded at different times or by different people so that
+       each description is a full description, using <STRONG>infocmp</STRONG>  will  show  what
+       can be done to change one description to be relative to the other.
+
+       A capability will be printed with an at-sign (@) if it no longer exists
+       in the first <EM>termname</EM>, but one of the other <EM>termname</EM> entries contains a
+       value for it.  A capability's value will be printed if the value in the
+       first <EM>termname</EM> is not found in any of the other <EM>termname</EM> entries, or if
+       the  first of the other <EM>termname</EM> entries that has this capability gives
+       a different value for the capability than that in the first <EM>termname</EM>.
+
+       The order of the other <EM>termname</EM>  entries  is  significant.   Since  the
+       terminfo  compiler  <STRONG>tic</STRONG>  does a left-to-right scan of the capabilities,
+       specifying two <STRONG>use=</STRONG> entries that contain differing entries for the same
+       capabilities will produce different results depending on the order that
+       the entries are given in.  <STRONG>infocmp</STRONG> will flag any  such  inconsistencies
+       between the other <EM>termname</EM> entries as they are found.
+
+       Alternatively, specifying a capability <EM>after</EM> a <STRONG>use=</STRONG> entry that contains
+       that capability will cause the  second  specification  to  be  ignored.
+       Using  <STRONG>infocmp</STRONG>  to recreate a description can be a useful check to make
+       sure that everything was specified correctly  in  the  original  source
+       description.
+
+       Another  error  that  does not cause incorrect compiled files, but will
+       slow down the compilation time, is specifying extra  <STRONG>use=</STRONG>  fields  that
+       are superfluous.  <STRONG>infocmp</STRONG> will flag any other <EM>termname</EM> <EM>use=</EM> fields that
+       were not needed.
+
+   <STRONG>Changing</STRONG> <STRONG>Databases</STRONG> <STRONG>[-A</STRONG> <EM>directory</EM>] [-B <EM>directory</EM>]
+       Like  other  <STRONG>ncurses</STRONG>  utilities,  <STRONG>infocmp</STRONG>  looks   for   the   terminal
+       descriptions   in  several  places.   You  can  use  the  <STRONG>TERMINFO</STRONG>  and
+       <STRONG>TERMINFO_DIRS</STRONG> environment variables to override the compiled-in default
+       list of places to search (see <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG> for details).
+
+       You  can  also use the options <STRONG>-A</STRONG> and <STRONG>-B</STRONG> to override the list of places
+       to search when comparing terminal descriptions:
+
+       <STRONG>o</STRONG>   The <STRONG>-A</STRONG> option sets the location for the first <EM>termname</EM>
+
+       <STRONG>o</STRONG>   The <STRONG>-B</STRONG> option sets the location for the other <EM>termnames</EM>.
+
+       Using these options, it is  possible  to  compare  descriptions  for  a
+       terminal  with  the  same name located in two different databases.  For
+       instance, you can use this feature for comparing descriptions  for  the
+       same terminal created by different people.

+       <STRONG>-0</STRONG>   causes the fields to be printed on one line, without wrapping.
+
+       <STRONG>-1</STRONG>   causes the fields to be printed out one to a line.  Otherwise, the
+            fields will be printed several to a line to a maximum width of  60
+            characters.
+
+       <STRONG>-a</STRONG>   tells  <STRONG>infocmp</STRONG>  to  retain  commented-out capabilities rather than
+            discarding them.  Capabilities are  commented  by  prefixing  them
+            with a period.
+
+       <STRONG>-D</STRONG>   tells <STRONG>infocmp</STRONG> to print the database locations that it knows about,
+            and exit.
+
+       <STRONG>-E</STRONG>   Dump the capabilities of the given terminal as tables,  needed  in
+            the   C   initializer  for  a  TERMTYPE  structure  (the  terminal
+            capability structure in the <STRONG>&lt;term.h&gt;</STRONG>).  This option is useful  for
+            preparing  versions  of  the  curses library hardwired for a given
+            terminal type.  The tables are all declared static, and are  named
+            according  to  the type and the name of the corresponding terminal
+            entry.
+
+            Before ncurses 5.0, the split between the <STRONG>-e</STRONG> and  <STRONG>-E</STRONG>  options  was
+            not  needed;  but  support  for extended names required making the
+            arrays  of  terminal  capabilities  separate  from  the   TERMTYPE
+            structure.
+
+       <STRONG>-e</STRONG>   Dump the capabilities of the given terminal as a C initializer for
+            a TERMTYPE structure (the terminal  capability  structure  in  the
+            <STRONG>&lt;term.h&gt;</STRONG>).   This  option  is useful for preparing versions of the
+            curses library hardwired for a given terminal type.
+
+       <STRONG>-F</STRONG>   compare terminfo files.  This assumes that two following arguments
+            are  filenames.   The  files  are  searched  for  pairwise matches
+            between entries, with two entries considered to match  if  any  of
+            their  names  do.   The  report  printed  to standard output lists
+            entries with no matches in the other file, and entries  with  more
+            than  one match.  For entries with exactly one match it includes a
+            difference report.  Normally, to reduce the volume of the  report,
+            use  references  are  not resolved before looking for differences,
+            but resolution can be forced by also specifying <STRONG>-r</STRONG>.
+
+       <STRONG>-f</STRONG>   Display complex terminfo strings which contain  if/then/else/endif
+            expressions indented for readability.
+
+       <STRONG>-G</STRONG>   Display  constant  literals  in  decimal  form  rather  than their
+            character equivalents.
+
+       <STRONG>-g</STRONG>   Display constant character literals in  quoted  form  rather  than

+            as starting/stopping keymap mode (<STRONG>smkx</STRONG>, <STRONG>rmkx</STRONG>).
+
+            For each string, the code tries to  analyze  it  into  actions  in
+            terms  of  the  other capabilities in the entry, certain X3.64/ISO
+            6429/ECMA-48 capabilities, and certain DEC VT-series private modes
+            (the  set  of  recognized  special sequences has been selected for
+            completeness over the existing terminfo  database).   Each  report
+            line  consists  of  the  capability  name, followed by a colon and
+            space, followed by a printable expansion of the capability  string
+            with   sections   matching   recognized  actions  translated  into

+
+               2  base64
+
+               3  hexadecimal and base64
+
+            For example, this prints the compiled terminfo value as  a  string
+            which could be assigned to the <STRONG>TERMINFO</STRONG> environment variable:
+
+                infocmp -0 -q -Q2
+
+       <STRONG>-q</STRONG>   This makes the output a little shorter:
+
+            <STRONG>o</STRONG>   Make  the  comparison listing shorter by omitting subheadings,
+                and using "-" for absent capabilities, "@" for canceled rather
+                than "NULL".
+
+            <STRONG>o</STRONG>   However,   show   differences  between  absent  and  cancelled
+                capabilities.
+
+            <STRONG>o</STRONG>   Omit the "Reconstructed from" comment for source listings.
+
+       <STRONG>-R</STRONG><EM>subset</EM>
+            Restrict output to a given subset.  This option is  for  use  with
+            archaic  versions of terminfo like those on SVr1, Ultrix, or HP-UX
+            that do not support the full set of SVR4/XSI Curses terminfo;  and
+            variants  such  as AIX that have their own extensions incompatible
+            with SVr4/XSI.
+
+            <STRONG>o</STRONG>   Available terminfo subsets are  "SVr1",  "Ultrix",  "HP",  and
+                "AIX"; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for details.
+
+            <STRONG>o</STRONG>   You  can  also  choose  the  subset  "BSD"  which selects only
+                capabilities with termcap equivalents  recognized  by  4.4BSD.
+                The <STRONG>-C</STRONG> option sets the "BSD" subset as a side-effect.
+
+            <STRONG>o</STRONG>   If  you  select  any  other value for <STRONG>-R</STRONG>, it is the same as no
+                subset, i.e.,  all  capabilities  are  used.   The  <STRONG>-I</STRONG>  option
+                likewise selects no subset as a side-effect.
+
+       <STRONG>-s</STRONG> <EM>[d|i|l|c]</EM>
+            The  <STRONG>-s</STRONG>  option sorts the fields within each type according to the
+            argument below:
+
+            <STRONG>d</STRONG>    leave fields in  the  order  that  they  are  stored  in  the
+                 <EM>terminfo</EM> database.
+
+            <STRONG>i</STRONG>    sort by <EM>terminfo</EM> name.
+
+            <STRONG>l</STRONG>    sort by the long C variable name.
+
+            <STRONG>c</STRONG>    sort by the <EM>termcap</EM> name.
+
+            If  the  <STRONG>-s</STRONG>  option  is  not given, the fields printed out will be
+            sorted alphabetically by  the  <STRONG>terminfo</STRONG>  name  within  each  type,
+            except  in  the  case of the <STRONG>-C</STRONG> or the <STRONG>-L</STRONG> options, which cause the
+            sorting to be done by the <STRONG>termcap</STRONG> name  or  the  long  C  variable
+            name, respectively.
+
+       <STRONG>-T</STRONG>   eliminates  size-restrictions  on  the  generated  text.   This is
+            mainly  useful  for  testing  and  analysis,  since  the  compiled
+            descriptions  are  limited  (e.g.,  1023  for  termcap,  4096  for
+            terminfo).
+
+       <STRONG>-t</STRONG>   tells <STRONG>tic</STRONG> to discard commented-out  capabilities.   Normally  when
+            translating  from terminfo to termcap, untranslatable capabilities
+            are commented-out.
+
+       <STRONG>-U</STRONG>   tells <STRONG>infocmp</STRONG> to not  post-process  the  data  after  parsing  the
+            source  file.   This  feature  helps  when  comparing  the  actual
+            contents of two source files, since  it  excludes  the  inferences
+            that <STRONG>infocmp</STRONG> makes to fill in missing data.
+
+       <STRONG>-V</STRONG>   reports the version of ncurses which was used in this program, and
+            exits.
+
+       <STRONG>-v</STRONG> <EM>n</EM> prints out tracing information on standard error  as  the  program
+            runs.
+
+            The  optional  parameter  <EM>n</EM>  is  a number from 1 to 10, inclusive,
+            indicating the desired level of detail of information.  If ncurses
+            is  built  without  tracing  support,  the  optional  parameter is
+            ignored.
+
+       <STRONG>-W</STRONG>   By itself, the <STRONG>-w</STRONG>  option  will  not  force  long  strings  to  be
+            wrapped.  Use the <STRONG>-W</STRONG> option to do this.
+
+       <STRONG>-w</STRONG> <EM>width</EM>
+            changes the output to <EM>width</EM> characters.
+
+       <STRONG>-x</STRONG>   print information for user-defined capabilities (see <STRONG>user_caps(5)</STRONG>.
+            These are extensions to  the  terminfo  repertoire  which  can  be
+            loaded using the <STRONG>-x</STRONG> option of <STRONG>tic</STRONG>.

+       Eric  Raymond  used  the  AT&amp;T  documentation  in  1995  to  provide an
+       equivalent <STRONG>infocmp</STRONG> for ncurses.   In  addition,  he  added  a  few  new
+       features such as:
+
+       <STRONG>o</STRONG>   the   <STRONG>-e</STRONG>   option,   to  support  <EM>fallback</EM>  (compiled-in)  terminal
+           descriptions
+
+       <STRONG>o</STRONG>   the <STRONG>-i</STRONG> option, to help with analysis
+
+       Later, Thomas Dickey added the <STRONG>-x</STRONG> (user-defined  capabilities)  option,
+       and  the  <STRONG>-E</STRONG>  option  to  support  fallback  entries  with user-defined
+       capabilities.
+
+       For a complete list, see the <EM>EXTENSIONS</EM> section.
+
+       In 2010, Roy Marples provided an <STRONG>infocmp</STRONG> program  for  NetBSD.   It  is
+       less  capable  than  the  SVr4  or ncurses versions (e.g., it lacks the
+       sorting options documented in X/Open), but does include the  <STRONG>-x</STRONG>  option
+       adapted from ncurses.

+
+       SVr4   infocmp  does  not  distinguish  between  absent  and  cancelled
+       capabilities.  Also, it shows missing integer capabilities as  <STRONG>-1</STRONG>  (the
+       internal   value   used   to   represent   missing   integers).    This

+

+       The  <STRONG>use_legacy_coding</STRONG>  function is an extension to the curses library.
+       It allows the caller to change  the  result  of  <STRONG>unctrl</STRONG>,  and  suppress
+       related checks within the library that would normally cause nonprinting
+       characters to be rendered in visible form.   This  affects  only  8-bit
+       characters.
+
+       The <EM>level</EM> parameter controls the result:
+
+              0    the   library  functions  normally,  rendering  nonprinting
+                   characters as described in <STRONG>unctrl</STRONG>.

+</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
+       The <STRONG>menu</STRONG> library provides terminal-independent facilities for composing
+       menu systems on character-cell terminals.  The library  includes:  item
+       routines,  which create and modify menu items; and menu routines, which
+       group items into  menus,  display  menus  on  the  screen,  and  handle
+       interaction with the user.
+
+       The <STRONG>menu</STRONG> library uses the <STRONG>curses</STRONG> libraries, and a curses initialization
+       routine such as <STRONG>initscr</STRONG> must  be  called  before  using  any  of  these
+       functions.   To  use  the  <STRONG>menu</STRONG>  library,  link with the options <STRONG>-lmenu</STRONG>
+       <STRONG>-lcurses</STRONG>.
+
+
+</PRE><H3><a name="h3-Current-Default-Values-for-Item-Attributes">Current Default Values for Item Attributes</a></H3><PRE>
+       The <STRONG>menu</STRONG> library maintains a default value for  item  attributes.   You
+       can  get  or  set  this default by calling the appropriate <STRONG>get_</STRONG> or <STRONG>set_</STRONG>
+       routine with a <STRONG>NULL</STRONG> item pointer.  Changing this default  with  a  <STRONG>set_</STRONG>
+       function  affects  future  item  creations,  but  does  not  change the
+       rendering of items already created.

+       Once a menu has been posted (displayed), you should funnel input events
+       to it through <STRONG>menu_driver</STRONG>.  This routine has three major input cases:
+
+       <STRONG>o</STRONG>   The input is a form navigation request.  Navigation  request  codes
+           are constants defined in <STRONG>&lt;form.h&gt;</STRONG>, which are distinct from the key-
+           and character codes returned by <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG>.
+
+       <STRONG>o</STRONG>   The input is a printable character.   Printable  characters  (which
+           must  be  positive,  less  than  256)  are checked according to the
+           program's locale settings.
+
+       <STRONG>o</STRONG>   The input is the KEY_MOUSE special key  associated  with  an  mouse
+           event.
+
+       The menu driver requests are as follows:
+
+       REQ_LEFT_ITEM
+            Move left to an item.
+
+       REQ_RIGHT_ITEM
+            Move right to an item.
+
+       REQ_UP_ITEM
+            Move up to an item.
+
+       REQ_DOWN_ITEM
+            Move down to an item.
+
+       REQ_SCR_ULINE
+            Scroll up a line.
+
+       REQ_SCR_DLINE
+            Scroll down a line.
+
+       REQ_SCR_DPAGE
+            Scroll down a page.
+
+       REQ_SCR_UPAGE
+            Scroll up a page.
+
+       REQ_FIRST_ITEM
+            Move to the first item.
+
+       REQ_LAST_ITEM
+            Move to the last item.
+
+       REQ_NEXT_ITEM
+            Move to the next item.
+
+       REQ_PREV_ITEM
+            Move to the previous item.
+
+       REQ_TOGGLE_ITEM
+            Select/deselect an item.
+
+       REQ_CLEAR_PATTERN
+            Clear the menu pattern buffer.
+
+       REQ_BACK_PATTERN
+            Delete the previous character from the pattern buffer.
+
+       REQ_NEXT_MATCH
+            Move to the next item matching the pattern match.
+
+       REQ_PREV_MATCH
+            Move to the previous item matching the pattern match.
+
+       If the second argument is a printable character, the code appends it to
+       the pattern buffer and attempts to move to the next item  matching  the
+       new pattern.  If there is no such match, <STRONG>menu_driver</STRONG> returns <STRONG>E_NO_MATCH</STRONG>
+       and deletes the appended character from the buffer.
+
+       If the second argument is one of the above  pre-defined  requests,  the
+       corresponding action is performed.
+
+
+</PRE><H3><a name="h3-MOUSE-HANDLING">MOUSE HANDLING</a></H3><PRE>
+       If  the  second  argument  is the KEY_MOUSE special key, the associated
+       mouse event is translated into one of the above  pre-defined  requests.
+       Currently only clicks in the user window (e.g., inside the menu display
+       area or the decoration window) are handled.
+
+       If you click above the display region of the menu:
+
+       <STRONG>o</STRONG>   a REQ_SCR_ULINE is generated for a single click,
+
+       <STRONG>o</STRONG>   a REQ_SCR_UPAGE is generated for a double-click and
+
+       <STRONG>o</STRONG>   a REQ_FIRST_ITEM is generated for a triple-click.
+
+       If you click below the display region of the menu:
+
+       <STRONG>o</STRONG>   a REQ_SCR_DLINE is generated for a single click,
+
+       <STRONG>o</STRONG>   a REQ_SCR_DPAGE is generated for a double-click and
+
+       <STRONG>o</STRONG>   a REQ_LAST_ITEM is generated for a triple-click.
+
+       If you click at an item inside the display area of the menu:
+
+       <STRONG>o</STRONG>   the menu cursor is positioned to that item.
+
+       <STRONG>o</STRONG>   If you double-click an item  a  REQ_TOGGLE_ITEM  is  generated  and
+           <STRONG>E_UNKNOWN_COMMAND</STRONG>  is  returned.   This  return  value makes sense,
+           because a double click usually means that an  item-specific  action
+           should be returned.  It is exactly the purpose of this return value
+           to signal that an application specific command should be executed.
+
+       <STRONG>o</STRONG>   If a translation into a request was done, <STRONG>menu_driver</STRONG>  returns  the
+           result of this request.
+
+       If  you clicked outside the user window or the mouse event could not be
+       translated into a menu request an <STRONG>E_REQUEST_DENIED</STRONG> is returned.

+</PRE><H3><a name="h3-APPLICATION-DEFINED-COMMANDS">APPLICATION-DEFINED COMMANDS</a></H3><PRE>
+       If the second argument is neither printable nor one of the  above  pre-

+       The function <STRONG>set_menu_format</STRONG> sets the maximum display size of the given
+       menu.  If this size is too small to display all menu  items,  the  menu
+       will  be  made  scrollable.   If  this  size  is  larger than the menus
+       subwindow and the subwindow is too small to  display  all  menu  items,
+       <STRONG>post_menu</STRONG> will fail.
+
+       The  default format is 16 rows, 1 column.  Calling <STRONG>set_menu_format</STRONG> with
+       a null menu pointer will change this default.  A  zero  row  or  column
+       argument  to  <STRONG>set_menu_format</STRONG> is interpreted as a request not to change
+       the current value.
+
+       The function <STRONG>menu_format</STRONG> returns the maximum-size constraints  for  the
+       given menu into the storage addressed by <STRONG>rows</STRONG> and <STRONG>cols</STRONG>.

+       In  order  to  make  menu selections visible on older terminals without
+       highlighting or color capability, the menu library marks selected items
+       in a menu with a prefix string.
+
+       The  function  <STRONG>set_menu_mark</STRONG>  sets  the mark string for the given menu.
+       Calling <STRONG>set_menu_mark</STRONG> with a null  menu  item  will  abolish  the  mark
+       string.   Note  that  changing the length of the mark string for a menu
+       while the menu is posted is likely to produce unhelpful behavior.
+
+       The default string is "-" (a dash).  Calling <STRONG>set_menu_mark</STRONG> with a  non-
+       <STRONG>NULL</STRONG> menu argument will change this default.
+
+       The function <STRONG>menu_mark</STRONG> returns the menu's mark string (or <STRONG>NULL</STRONG> if there
+       is none).

+       The function <STRONG>set_menu_opts</STRONG> sets all the given menu's option bits  (menu
+       option bits may be logically-OR'ed together).

+
+       O_ONEVALUE

+            Don't  wrap  around  next-item  and previous-item, requests to the
+            other end of the menu.
+
+       O_MOUSE_MENU
+            If user clicks with  the  mouse  and  it  does  not  fall  on  the

+       The  <STRONG>ncurses</STRONG>  library  routines  give  the  user a terminal-independent
+       method of updating  character  screens  with  reasonable  optimization.
+       This  implementation  is  "new  curses"  (ncurses)  and is the approved
+       replacement for 4.4BSD classic curses,  which  has  been  discontinued.
+       This describes <STRONG>ncurses</STRONG> version 6.4 (patch 20221231).
+
+       The  <STRONG>ncurses</STRONG>  library emulates the curses library of System V Release 4
+       UNIX, and XPG4 (X/Open Portability Guide) curses  (also  known  as  XSI
+       curses).   XSI  stands  for  X/Open  System  Interfaces Extension.  The
+       <STRONG>ncurses</STRONG> library is freely redistributable in source form.   Differences
+       from   the   SVr4  curses  are  summarized  under  the  <EM>EXTENSIONS</EM>  and
+       <EM>PORTABILITY</EM> sections below and described in detail  in  the  respective
+       <EM>EXTENSIONS</EM>, <EM>PORTABILITY</EM> and <EM>BUGS</EM> sections of individual man pages.
+
+       The  <STRONG>ncurses</STRONG>  library  also  provides  many  useful  extensions,  i.e.,
+       features which cannot be implemented by a  simple  add-on  library  but
+       which require access to the internals of the library.
+
+       A  program  using  these  routines  must  be  linked with the <STRONG>-lncurses</STRONG>
+       option, or (if it  has  been  generated)  with  the  debugging  library
+       <STRONG>-lncurses_g</STRONG>.   (Your  system  integrator  may also have installed these
+       libraries under the names  <STRONG>-lcurses</STRONG>  and  <STRONG>-lcurses_g</STRONG>.)   The  ncurses_g
+       library  generates  trace logs (in a file called "trace" in the current
+       directory) that describe curses  actions.   See  also  the  section  on
+       <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>.
+
+       The   <STRONG>ncurses</STRONG>   package   supports:  overall  screen,  window  and  pad
+       manipulation; output to  windows  and  pads;  reading  terminal  input;
+       control  over terminal and <STRONG>curses</STRONG> input and output options; environment
+       query routines; color manipulation; use of soft  label  keys;  terminfo
+       capabilities; and access to low-level terminal-manipulation routines.
+
+
+</PRE><H3><a name="h3-Initialization">Initialization</a></H3><PRE>
+       The  library uses the locale which the calling program has initialized.
+       That is normally done with <STRONG>setlocale(3)</STRONG>:
+
+           <STRONG>setlocale(LC_ALL,</STRONG> <STRONG>"");</STRONG>
+
+       If the locale is not initialized, the library assumes  that  characters
+       are  printable  as in ISO-8859-1, to work with certain legacy programs.
+       You should initialize the locale and not rely on  specific  details  of
+       the library when the locale has not been setup.
+
+       The  function  <STRONG>initscr</STRONG>  or  <STRONG>newterm</STRONG>  must  be  called to initialize the
+       library before any of the other routines that  deal  with  windows  and
+       screens  are  used.   The  routine  <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG>  must  be  called before
+       exiting.
+
+       To get character-at-a-time input  without  echoing  (most  interactive,
+       screen  oriented  programs want this), the following sequence should be
+       used:
+
+           <STRONG>initscr();</STRONG> <STRONG>cbreak();</STRONG> <STRONG>noecho();</STRONG>
+
+       Most programs would additionally use the sequence:
+
+           <STRONG>intrflush(stdscr,</STRONG> <STRONG>FALSE);</STRONG>
+           <STRONG>keypad(stdscr,</STRONG> <STRONG>TRUE);</STRONG>
+
+       Before a <STRONG>curses</STRONG> program is run, the tab stops of the terminal should be
+       set  and  its initialization strings, if defined, must be output.  This
+       can be done  by  executing  the  <STRONG>tput</STRONG>  <STRONG>init</STRONG>  command  after  the  shell
+       environment  variable  <STRONG>TERM</STRONG>  has  been  exported.   <STRONG>tset(1)</STRONG>  is usually
+       responsible for doing this.  [See <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for further details.]
+
+
+</PRE><H3><a name="h3-Datatypes">Datatypes</a></H3><PRE>
+       The <STRONG>ncurses</STRONG> library permits manipulation  of  data  structures,  called
+       <EM>windows</EM>,   which  can  be  thought  of  as  two-dimensional  arrays  of
+       characters representing all or part of a CRT screen.  A default  window
+       called  <STRONG>stdscr</STRONG>,  which is the size of the terminal screen, is supplied.
+       Others may be created with <STRONG>newwin</STRONG>.
+
+       Note that <STRONG>curses</STRONG> does not handle overlapping windows,  that's  done  by
+       the  <STRONG><A HREF="panel.3x.html">panel(3x)</A></STRONG>  library.   This means that you can either use <STRONG>stdscr</STRONG> or
+       divide the screen into tiled windows  and  not  using  <STRONG>stdscr</STRONG>  at  all.
+       Mixing the two will result in unpredictable, and undesired, effects.
+
+       Windows  are referred to by variables declared as <STRONG>WINDOW</STRONG> <STRONG>*</STRONG>.  These data
+       structures are manipulated with routines described here  and  elsewhere
+       in  the <STRONG>ncurses</STRONG> manual pages.  Among those, the most basic routines are
+       <STRONG>move</STRONG> and <STRONG>addch</STRONG>.  More general versions of these routines  are  included
+       with  names  beginning  with  <STRONG>w</STRONG>, allowing the user to specify a window.
+       The routines not beginning with <STRONG>w</STRONG> affect <STRONG>stdscr</STRONG>.
+
+       After using routines to manipulate a  window,  <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG>  is  called,
+       telling  <STRONG>curses</STRONG>  to  make  the user's CRT screen look like <STRONG>stdscr</STRONG>.  The
+       characters in a window are actually  of  type  <STRONG>chtype</STRONG>,  (character  and
+       attribute  data) so that other information about the character may also
+       be stored with each character.
+
+       Special windows called <EM>pads</EM> may also be manipulated.  These are windows
+       which  are not constrained to the size of the screen and whose contents
+       need  not  be  completely  displayed.   See   <STRONG><A HREF="curs_pad.3x.html">curs_pad(3x)</A></STRONG>   for   more
+       information.
+
+       In  addition  to drawing characters on the screen, video attributes and
+       colors may be supported, causing the characters  to  show  up  in  such
+       modes  as  underlined,  in reverse video, or in color on terminals that
+       support such display enhancements.   Line  drawing  characters  may  be
+       specified  to  be  output.   On input, <STRONG>curses</STRONG> is also able to translate
+       arrow and function keys that  transmit  escape  sequences  into  single
+       values.   The  video  attributes,  line  drawing  characters, and input
+       values use names, defined in <STRONG>&lt;curses.h&gt;</STRONG>, such as <STRONG>A_REVERSE</STRONG>,  <STRONG>ACS_HLINE</STRONG>,
+       and <STRONG>KEY_LEFT</STRONG>.
+
+
+</PRE><H3><a name="h3-Environment-variables">Environment variables</a></H3><PRE>
+       If  the  environment  variables  <STRONG>LINES</STRONG>  and  <STRONG>COLUMNS</STRONG> are set, or if the
+       program  is  executing  in  a  window  environment,  line  and   column
+       information  in  the  environment  will  override  information  read by
+       <EM>terminfo</EM>.  This would affect a program running in an  AT&amp;T  630  layer,
+       for   example,   where   the  size  of  a  screen  is  changeable  (see
+       <STRONG>ENVIRONMENT</STRONG>).
+
+       If the environment variable <STRONG>TERMINFO</STRONG>  is  defined,  any  program  using
+       <STRONG>curses</STRONG>  checks  for  a local terminal definition before checking in the
+       standard place.  For example, if <STRONG>TERM</STRONG>  is  set  to  <STRONG>att4424</STRONG>,  then  the
+       compiled terminal definition is found in
+
+           <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
+
+       (The  <STRONG>a</STRONG> is copied from the first letter of <STRONG>att4424</STRONG> to avoid creation of
+       huge directories.)  However,  if  <STRONG>TERMINFO</STRONG>  is  set  to  <STRONG>$HOME/myterms</STRONG>,
+       <STRONG>curses</STRONG> first checks
+
+           <STRONG>$HOME/myterms/a/att4424</STRONG>,
+
+       and if that fails, it then checks
+
+           <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
+
+       This  is  useful  for developing experimental definitions or when write
+       permission in <STRONG>/usr/share/terminfo</STRONG> is not available.
+
+       The integer variables <STRONG>LINES</STRONG> and <STRONG>COLS</STRONG> are defined in <STRONG>&lt;curses.h&gt;</STRONG> and will
+       be  filled  in  by  <STRONG>initscr</STRONG> with the size of the screen.  The constants
+       <STRONG>TRUE</STRONG> and <STRONG>FALSE</STRONG> have the values <STRONG>1</STRONG> and <STRONG>0</STRONG>, respectively.
+
+       The <STRONG>curses</STRONG> routines also define the <STRONG>WINDOW</STRONG> <STRONG>*</STRONG> variable <STRONG>curscr</STRONG>  which  is
+       used  for  certain  low-level  operations like clearing and redrawing a
+       screen containing garbage.  The <STRONG>curscr</STRONG>  can  be  used  in  only  a  few
+       routines.
+
+
+</PRE><H3><a name="h3-Routine-and-Argument-Names">Routine and Argument Names</a></H3><PRE>
+       Many  <STRONG>curses</STRONG> routines have two or more versions.  The routines prefixed
+       with <EM>w</EM> require a window argument.  The routines prefixed with <EM>p</EM> require
+       a pad argument.  Those without a prefix generally use <STRONG>stdscr</STRONG>.
+
+       The  routines  prefixed with <STRONG>mv</STRONG> require a <EM>y</EM> and <EM>x</EM> coordinate to move to
+       before performing the appropriate action.  The <STRONG>mv</STRONG> routines imply a call
+       to  <STRONG>move</STRONG> before the call to the other routine.  The coordinate <EM>y</EM> always
+       refers to the row (of the window), and <EM>x</EM> always refers to  the  column.
+       The upper left-hand corner is always (0,0), not (1,1).
+
+       The  routines prefixed with <STRONG>mvw</STRONG> take both a window argument and <EM>x</EM> and <EM>y</EM>
+       coordinates.  The  window  argument  is  always  specified  before  the
+       coordinates.
+
+       In  each case, <EM>win</EM> is the window affected, and <EM>pad</EM> is the pad affected;
+       <EM>win</EM> and <EM>pad</EM> are always pointers to type <STRONG>WINDOW</STRONG>.
+
+       Option setting routines require a Boolean flag <EM>bf</EM> with the  value  <STRONG>TRUE</STRONG>
+       or  <STRONG>FALSE</STRONG>;  <EM>bf</EM>  is always of type <STRONG>bool</STRONG>.  Most of the data types used in
+       the library routines, such as <STRONG>WINDOW</STRONG>,  <STRONG>SCREEN</STRONG>,  <STRONG>bool</STRONG>,  and  <STRONG>chtype</STRONG>  are
+       defined  in  <STRONG>&lt;curses.h&gt;</STRONG>.   Types used for the terminfo routines such as
+       <STRONG>TERMINAL</STRONG> are defined in <STRONG>&lt;term.h&gt;</STRONG>.
+
+       This  manual  page  describes  functions  which  may  appear   in   any
+       configuration  of  the library.  There are two common configurations of
+       the library:
+
+          <EM>ncurses</EM>
+               the "normal" library,  which  handles  8-bit  characters.   The
+               normal   (8-bit)   library   stores  characters  combined  with
+               attributes in <STRONG>chtype</STRONG> data.
+
+               Attributes alone (no corresponding character) may be stored  in
+               <STRONG>chtype</STRONG> or the equivalent <STRONG>attr_t</STRONG> data.  In either case, the data
+               is stored in something like an integer.
+
+               Each cell (row and column) in a <STRONG>WINDOW</STRONG> is stored as a <STRONG>chtype</STRONG>.
+
+          <EM>ncursesw</EM>
+               the  so-called  "wide"   library,   which   handles   multibyte
+               characters  (see the section on <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>).  The
+               "wide" library includes all of  the  calls  from  the  "normal"
+               library.   It  adds about one third more calls using data types
+               which store multibyte characters:
+
+               <STRONG>cchar_t</STRONG>
+                    corresponds to <STRONG>chtype</STRONG>.  However it is a structure, because
+                    more  data  is  stored  than can fit into an integer.  The
+                    characters are large enough  to  require  a  full  integer
+                    value - and there may be more than one character per cell.
+                    The video attributes and  color  are  stored  in  separate
+                    fields of the structure.
+
+                    Each  cell  (row  and  column)  in a <STRONG>WINDOW</STRONG> is stored as a
+                    <STRONG>cchar_t</STRONG>.
+
+                    The <STRONG><A HREF="curs_getcchar.3x.html">setcchar(3x)</A></STRONG>  and  <STRONG><A HREF="curs_getcchar.3x.html">getcchar(3x)</A></STRONG>  functions  store  and
+                    retrieve the data from a <STRONG>cchar_t</STRONG> structure.
+
+               <STRONG>wchar_t</STRONG>
+                    stores  a  "wide"  character.  Like <STRONG>chtype</STRONG>, this may be an
+                    integer.
+
+               <STRONG>wint_t</STRONG>
+                    stores a <STRONG>wchar_t</STRONG> or <STRONG>WEOF</STRONG> - not the same, though  both  may
+                    have the same size.
+
+               The  "wide"  library provides new functions which are analogous
+               to functions in  the  "normal"  library.   There  is  a  naming
+               convention  which  relates  many of the normal/wide variants: a
+               "_w" is inserted into the name.  For  example,  <STRONG>waddch</STRONG>  becomes
+               <STRONG>wadd_wch</STRONG>.

+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       Routines  that return an integer return <STRONG>ERR</STRONG> upon failure and an integer
+       value other than <STRONG>ERR</STRONG> upon successful completion, unless otherwise noted
+       in the routine descriptions.
+
+       As  a  general  rule,  routines  check  for  null  pointers  passed  as
+       parameters, and handle this as an error.
+
+       All macros return  the  value  of  the  <STRONG>w</STRONG>  version,  except  <STRONG>setscrreg</STRONG>,
+       <STRONG>wsetscrreg</STRONG>,  <STRONG>getyx</STRONG>,  <STRONG>getbegyx</STRONG>,  and  <STRONG>getmaxyx</STRONG>.   The  return  values of
+       <STRONG>setscrreg</STRONG>, <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>,  <STRONG>getbegyx</STRONG>,  and  <STRONG>getmaxyx</STRONG>  are  undefined
+       (i.e.,  these  should  not be used as the right-hand side of assignment
+       statements).
+
+       Functions with a "mv" prefix first  perform  a  cursor  movement  using
+       <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+       the window pointer  is  null.   Most  "mv"-prefixed  functions  (except
+       variadic  functions  such  as <STRONG>mvprintw</STRONG>) are provided both as macros and
+       functions.
+
+       Routines that return pointers return <STRONG>NULL</STRONG> on error.

+
+</PRE><H2><a name="h2-ENVIRONMENT">ENVIRONMENT</a></H2><PRE>
+       The following  environment  symbols  are  useful  for  customizing  the
+       runtime  behavior of the <STRONG>ncurses</STRONG> library.  The most important ones have
+       been already discussed in detail.
+
+
+</PRE><H3><a name="h3-CC-command-character">CC command-character</a></H3><PRE>
+       When set, change occurrences of the command_character (i.e., the  <STRONG>cmdch</STRONG>
+       capability)  of  the  loaded  terminfo  entries  to  the  value of this
+       variable.  Very few terminfo entries provide this feature.
+
+       Because this name is also used in development environments to represent
+       the C compiler's name, <STRONG>ncurses</STRONG> ignores it if it does not happen to be a
+       single character.
+
+
+</PRE><H3><a name="h3-BAUDRATE">BAUDRATE</a></H3><PRE>
+       The  debugging  library  checks  this  environment  variable  when  the
+       application  has  redirected  output to a file.  The variable's numeric
+       value is used for the baudrate.  If no value  is  found,  <STRONG>ncurses</STRONG>  uses
+       9600.  This allows testers to construct repeatable test-cases that take
+       into account costs that depend on baudrate.
+
+
+</PRE><H3><a name="h3-COLUMNS">COLUMNS</a></H3><PRE>
+       Specify the width of the screen in characters.  Applications running in
+       a  windowing  environment  usually  are able to obtain the width of the
+       window in which they are executing.  If neither the <STRONG>COLUMNS</STRONG>  value  nor
+       the  terminal's  screen  size is available, <STRONG>ncurses</STRONG> uses the size which
+       may be specified in the terminfo database (i.e., the <STRONG>cols</STRONG> capability).
+
+       It is important that your  application  use  a  correct  size  for  the
+       screen.   This  is  not always possible because your application may be
+       running on a host which does not honor NAWS (Negotiations About  Window
+       Size),  or  because  you  are  temporarily  running  as  another  user.
+       However, setting <STRONG>COLUMNS</STRONG> and/or <STRONG>LINES</STRONG> overrides the  library's  use  of
+       the screen size obtained from the operating system.
+
+       Either  <STRONG>COLUMNS</STRONG>  or <STRONG>LINES</STRONG> symbols may be specified independently.  This
+       is  mainly  useful  to  circumvent  legacy  misfeatures   of   terminal
+       descriptions,  e.g.,  xterm  which commonly specifies a 65 line screen.
+       For best results, <STRONG>lines</STRONG> and <STRONG>cols</STRONG> should not be specified in a  terminal
+       description for terminals which are run as emulations.
+
+       Use  the  <STRONG>use_env</STRONG>  function  to disable all use of external environment
+       (but not including system calls) to determine the screen size.  Use the
+       <STRONG>use_tioctl</STRONG> function to update <STRONG>COLUMNS</STRONG> or <STRONG>LINES</STRONG> to match the screen size
+       obtained from system calls or the terminal database.
+
+
+</PRE><H3><a name="h3-ESCDELAY">ESCDELAY</a></H3><PRE>
+       Specifies the total time, in milliseconds, for which ncurses will await
+       a  character  sequence,  e.g., a function key.  The default value, 1000
+       milliseconds, is enough for most uses.  However, it is made a  variable
+       to accommodate unusual applications.
+
+       The  most common instance where you may wish to change this value is to
+       work with slow hosts, e.g., running on a network.  If the  host  cannot
+       read  characters rapidly enough, it will have the same effect as if the
+       terminal did not send characters  rapidly  enough.   The  library  will
+       still see a timeout.
+
+       Note  that  xterm  mouse  events  are built up from character sequences
+       received from the xterm.   If  your  application  makes  heavy  use  of
+       multiple-clicking,  you may wish to lengthen this default value because
+       the timeout applies to the composed multi-click event as  well  as  the
+       individual clicks.
+
+       In addition to the environment variable, this implementation provides a
+       global variable with the same name.  Portable applications  should  not
+       rely  upon  the  presence  of  ESCDELAY in either form, but setting the
+       environment variable rather than the global variable  does  not  create
+       problems when compiling an application.

+       Most of the terminal descriptions in the terminfo database are  written
+       for  real  "hardware"  terminals.   Many  people use terminal emulators
+       which run in a windowing environment and use curses-based applications.
+       Terminal  emulators  can  duplicate  all  of the important aspects of a
+       hardware terminal, but they do not  have  the  same  limitations.   The
+       chief  limitation  of  a  hardware terminal from the standpoint of your
+       application is the management of  dataflow,  i.e.,  timing.   Unless  a
+       hardware  terminal  is  interfaced  into a terminal concentrator (which
+       does flow control), it (or  your  application)  must  manage  dataflow,
+       preventing  overruns.   The cheapest solution (no hardware cost) is for
+       your program to do this by pausing after operations that  the  terminal
+       does slowly, such as clearing the display.
+
+       As  a  result,  many  terminal  descriptions (including the vt100) have
+       delay times embedded.  You may wish to use these descriptions, but  not
+       want to pay the performance penalty.
+
+       Set  the  NCURSES_NO_PADDING  environment  variable  to disable all but
+       mandatory padding.  Mandatory padding is used  as  a  part  of  special
+       control sequences such as <STRONG>flash</STRONG>.

+       This setting is obsolete.  Before changes

+
+          <STRONG>o</STRONG>   continued though 5.9 patch 20130126
+
+       <STRONG>ncurses</STRONG>  enabled  buffered output during terminal initialization.  This
+       was done (as in SVr4 curses)  for  performance  reasons.   For  testing
+       purposes,  both  of  <STRONG>ncurses</STRONG> and certain applications, this feature was
+       made optional.  Setting the NCURSES_NO_SETBUF variable disabled  output
+       buffering,  leaving  the output in the original (usually line buffered)
+       mode.
+
+       In the current implementation, ncurses performs its own  buffering  and
+       does  not require this workaround.  It does not modify the buffering of
+       the standard output.
+
+       The reason for the change was to make the behavior for  interrupts  and
+       other   signals   more   robust.    One   drawback   is   that  certain
+       nonconventional programs would mix ordinary stdio  calls  with  ncurses
+       calls  and (usually) work.  This is no longer possible since ncurses is
+       not using the buffered standard output but its own output (to the  same
+       file  descriptor).  As a special case, the low-level calls such as <STRONG>putp</STRONG>
+       still use the standard output.  But high-level curses calls do not.

+       During initialization, the <STRONG>ncurses</STRONG> library  checks  for  special  cases

+       capabilities) described in  the  terminfo  are  known  to  be  missing.
+       Specifically,  when  running  in  a  UTF-8  locale,  the  Linux console

+       <STRONG>TERM</STRONG>  environment  variable  for  these.   For other special cases, you
+       should set this environment variable.  Doing this tells ncurses to  use
+       Unicode values which correspond to the VT100 line-drawing glyphs.  That
+       works for the special cases cited, and is likely to work  for  terminal
+       emulators.
+
+       When  setting  this  variable,  you  should  set it to a nonzero value.
+       Setting it to zero (or to a nonnumber) disables the special  check  for

+
+       As  an  alternative  to the environment variable, ncurses checks for an
+       extended terminfo capability <STRONG>U8</STRONG>.  This is a  numeric  capability  which

+       terminal databases:
+
+       <STRONG>o</STRONG>   Normally these are stored in a directory tree, using subdirectories
+           named by the first letter of the terminal names therein.
+
+           This is the scheme used in System V, which legacy Unix systems use,
+           and the <STRONG>TERMINFO</STRONG> variable is used by <EM>curses</EM> applications  on  those
+           systems to override the default location of the terminal database.
+
+       <STRONG>o</STRONG>   If  <STRONG>ncurses</STRONG>  is  built  to use hashed databases, then each entry in

+
+           rather than
+
+               /usr/share/terminfo/
+
+           The hashed database uses less disk-space and  is  a  little  faster
+           than  the  directory  tree.   However, some applications assume the
+           existence of the directory tree, reading it  directly  rather  than
+           using the terminfo library calls.
+
+       <STRONG>o</STRONG>   If  <STRONG>ncurses</STRONG>  is  built  with  a  support  for reading termcap files

+       using <STRONG>ncurses</STRONG>:
+

+
+            This  option  is  used to avoid filename conflicts when <STRONG>ncurses</STRONG> is
+            not the main implementation of curses of the computer.  If <STRONG>ncurses</STRONG>
+            is  installed  disabling  overwrite,  it  puts  its  headers  in a
+            subdirectory, e.g.,
+
+                <STRONG>#include</STRONG> <STRONG>&lt;ncurses/curses.h&gt;</STRONG>
+
+            It also omits a  symbolic  link  which  would  allow  you  to  use
+            <STRONG>-lcurses</STRONG> to build executables.
+
+       --enable-widec
+            The   configure   script   renames   the   library   and  (if  the
+            <STRONG>--disable-overwrite</STRONG> option is used) puts the  header  files  in  a
+            different  subdirectory.   All  of  the  library  names have a "w"
+            appended to them, i.e., instead of
+
+                <STRONG>-lncurses</STRONG>
+
+            you link with
+
+                <STRONG>-lncursesw</STRONG>
+
+            You must also enable the wide-character  features  in  the  header
+            file  when  compiling  for  the  wide-character library to use the
+            extended (wide-character) functions.   The  symbol  which  enables
+            these features has changed since XSI Curses, Issue 4:
+
+            <STRONG>o</STRONG>   Originally,  the  wide-character  feature  required the symbol
+                <STRONG>_XOPEN_SOURCE_EXTENDED</STRONG>  but  that  was  only  valid  for  XPG4
+                (1996).
+
+            <STRONG>o</STRONG>   Later,  that was deemed conflicting with <STRONG>_XOPEN_SOURCE</STRONG> defined
+                to 500.
+
+            <STRONG>o</STRONG>   As of mid-2018, none of the features  in  this  implementation
+                require  a  <STRONG>_XOPEN_SOURCE</STRONG>  feature greater than 600.  However,
+                X/Open Curses, Issue 7 (2009) recommends defining it to 700.
+
+            <STRONG>o</STRONG>   Alternatively,  you  can  enable  the  feature   by   defining
+                <STRONG>NCURSES_WIDECHAR</STRONG>  with  the caveat that some other header file
+                than <STRONG>curses.h</STRONG> may require a specific value  for  <STRONG>_XOPEN_SOURCE</STRONG>
+                (or a system-specific symbol).
+
+            The  <STRONG>curses.h</STRONG>  file  which  is  installed  for  the wide-character
+            library is designed to be compatible  with  the  normal  library's
+            header.   Only  the size of the <STRONG>WINDOW</STRONG> structure differs, and very
+            few applications require more than a pointer to <STRONG>WINDOW</STRONG>s.
+
+            If  the  headers  are  installed  allowing  overwrite,  the  wide-
+            character  library's  headers  should  be installed last, to allow
+            applications to be built using either library from the same set of
+            headers.

+            <STRONG>--enable-widec</STRONG>).
+
+            The global variables such as <STRONG>LINES</STRONG> are replaced by macros to allow
+            read-only access.  At the same time, setter-functions are provided
+            to  set  these  values.   Some applications (very few) may require

+       The <STRONG>ncurses</STRONG> library can be compiled with an option (<STRONG>-DUSE_GETCAP</STRONG>)  that
+       falls  back  to  the  old-style /etc/termcap file if the terminal setup
+       code cannot find a terminfo entry corresponding to <STRONG>TERM</STRONG>.  Use  of  this
+       feature  is  not  recommended,  as  it  essentially  includes an entire
+       termcap compiler in the <STRONG>ncurses</STRONG> startup code, at  significant  cost  in
+       core and startup cycles.
+
+       The  <STRONG>ncurses</STRONG>  library includes facilities for capturing mouse events on
+       certain terminals (including xterm).   See  the  <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG>  manual
+       page for details.
+
+       The  <STRONG>ncurses</STRONG>  library  includes  facilities  for  responding  to window

+       the library may be configured with a <STRONG>SIGWINCH</STRONG> handler.
+
+       The <STRONG>ncurses</STRONG> library extends the fixed set of function key  capabilities
+       of  terminals by allowing the application designer to define additional
+       key sequences at runtime.  See the <STRONG><A HREF="define_key.3x.html">define_key(3x)</A></STRONG> <STRONG><A HREF="key_defined.3x.html">key_defined(3x)</A></STRONG>,  and

+
+       The  <STRONG>ncurses</STRONG>  library  can  exploit the capabilities of terminals which
+       implement the ISO-6429 SGR 39 and  SGR  49  controls,  which  allow  an
+       application  to  reset  the  terminal  to  its  original foreground and
+       background colors.  From the users'  perspective,  the  application  is
+       able  to  draw  colored  text  on  a  background  whose  color  is  set
+       independently, providing better control over color contrasts.  See  the
+       <STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG> manual page for details.
+
+       The  <STRONG>ncurses</STRONG>  library  includes  a  function  for directing application

+
+       A  small  number  of local differences (that is, individual differences

+       In  many cases, X/Open Curses is vague about error conditions, omitting

+
+       Unlike other  implementations,  this  one  checks  parameters  such  as
+       pointers  to  WINDOW  structures to ensure they are not null.  The main
+       reason for providing this  behavior  is  to  guard  against  programmer
+       error.   The  standard interface does not provide a way for the library
+       to tell an application which of several possible errors were  detected.
+       Relying  on  this  (or  some other) extension will adversely affect the

+       Most of the extensions provided by ncurses have not been  standardized.
+       Some  have  been  incorporated  into  other  implementations,  such  as
+       PDCurses or NetBSD curses.  Here are a few to consider:
+
+       <STRONG>o</STRONG>   The routine <STRONG>has_key</STRONG> is not part of XPG4, nor is it present in SVr4.
+           See the <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG> manual page for details.
+
+       <STRONG>o</STRONG>   The  routine  <STRONG>slk_attr</STRONG>  is  not  part of XPG4, nor is it present in
+           SVr4.  See the <STRONG><A HREF="curs_slk.3x.html">curs_slk(3x)</A></STRONG> manual page for details.
+
+       <STRONG>o</STRONG>   The routines <STRONG>getmouse</STRONG>, <STRONG>mousemask</STRONG>,  <STRONG>ungetmouse</STRONG>,  <STRONG>mouseinterval</STRONG>,  and
+           <STRONG>wenclose</STRONG>  relating  to  mouse interfacing are not part of XPG4, nor
+           are they present in SVr4.  See the <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> manual  page  for
+           details.
+
+       <STRONG>o</STRONG>   The  routine  <STRONG>mcprint</STRONG>  was  not  present  in  any  previous  curses
+           implementation.  See the <STRONG><A HREF="curs_print.3x.html">curs_print(3x)</A></STRONG> manual page for details.
+
+       <STRONG>o</STRONG>   The routine <STRONG>wresize</STRONG> is not part of XPG4, nor is it present in SVr4.
+           See the <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG> manual page for details.
+
+       <STRONG>o</STRONG>   The   WINDOW  structure's  internal  details  can  be  hidden  from
+           application programs.  See <STRONG><A HREF="curs_opaque.3x.html">curs_opaque(3x)</A></STRONG> for  the  discussion  of
+           <STRONG>is_scrollok</STRONG>, etc.
+
+       <STRONG>o</STRONG>   This  implementation  can  be  configured  to  provide  rudimentary
+           support for multi-threaded applications.  See <STRONG><A HREF="curs_threads.3x.html">curs_threads(3x)</A></STRONG>  for
+           details.

+       In  historic  curses  versions, delays embedded in the capabilities <STRONG>cr</STRONG>,

+       bytes.  This  method  is  slightly  more  expensive,  but  narrows  the
+       interface  to the UNIX kernel significantly and increases the package's
+       portability correspondingly.
+
+
+</PRE><H3><a name="h3-Header-files">Header files</a></H3><PRE>
+       The header file <STRONG>&lt;curses.h&gt;</STRONG>  automatically  includes  the  header  files
+       <STRONG>&lt;stdio.h&gt;</STRONG> and <STRONG>&lt;unctrl.h&gt;</STRONG>.
+
+       X/Open Curses has more to say, but does not finish the story:
+
+           The  inclusion  of &lt;curses.h&gt; may make visible all symbols from the
+           headers &lt;stdio.h&gt;, &lt;term.h&gt;, &lt;termios.h&gt;, and &lt;wchar.h&gt;.
+
+       Here is a more complete story:
+
+       <STRONG>o</STRONG>   Starting  with  BSD  curses,  all  implementations  have   included
+           &lt;stdio.h&gt;.
+
+           BSD  curses  included  &lt;curses.h&gt;  and  &lt;unctrl.h&gt; from an internal
+           header "curses.ext" ("ext" was a short name for <EM>externs</EM>).
+
+           BSD curses used &lt;stdio.h&gt; internally (for <STRONG>printw</STRONG>  and  <STRONG>scanw</STRONG>),  but
+           nothing in &lt;curses.h&gt; itself relied upon &lt;stdio.h&gt;.
+
+       <STRONG>o</STRONG>   SVr2  curses  added <STRONG><A HREF="curs_initscr.3x.html">newterm(3x)</A></STRONG>, which relies upon &lt;stdio.h&gt;.  That
+           is, the function prototype uses <STRONG>FILE</STRONG>.
+
+           SVr4 curses added <STRONG>putwin</STRONG> and <STRONG>getwin</STRONG>, which also use &lt;stdio.h&gt;.
+
+           X/Open Curses documents all three of these functions.
+
+           SVr4 curses and X/Open Curses  do  not  require  the  developer  to
+           include  &lt;stdio.h&gt;  before  including  &lt;curses.h&gt;.   Both  document
+           curses showing &lt;curses.h&gt; as the only required header.
+
+           As a result, standard &lt;curses.h&gt; will always include &lt;stdio.h&gt;.
+
+       <STRONG>o</STRONG>   X/Open Curses  is  inconsistent  with  respect  to  SVr4  regarding
+           &lt;unctrl.h&gt;.
+
+           As   noted  in  <STRONG><A HREF="curs_util.3x.html">curs_util(3x)</A></STRONG>,  ncurses  includes  &lt;unctrl.h&gt;  from
+           &lt;curses.h&gt; (like SVr4).
+
+       <STRONG>o</STRONG>   X/Open's comments about &lt;term.h&gt; and &lt;termios.h&gt; may refer to HP-UX
+           and AIX:
+
+           HP-UX curses includes &lt;term.h&gt; from &lt;curses.h&gt; to declare <STRONG>setupterm</STRONG>
+           in curses.h, but ncurses (and Solaris curses) do not.
+
+           AIX curses includes &lt;term.h&gt; and &lt;termios.h&gt;.  Again, ncurses  (and
+           Solaris curses) do not.
+
+       <STRONG>o</STRONG>   X/Open  says  that &lt;curses.h&gt; <EM>may</EM> include &lt;term.h&gt;, but there is no
+           requirement that it do that.
+
+           Some  programs  use  functions  declared  in  both  &lt;curses.h&gt;  and
+           &lt;term.h&gt;,  and  must include both headers in the same module.  Very
+           old versions of AIX curses  required  including  &lt;curses.h&gt;  before
+           including &lt;term.h&gt;.
+
+           Because  ncurses  header files include the headers needed to define
+           datatypes used in the headers, ncurses header files can be included
+           in  any  order.  But for portability, you should include &lt;curses.h&gt;
+           before &lt;term.h&gt;.
+
+       <STRONG>o</STRONG>   X/Open Curses says <EM>"may</EM> <EM>make</EM> <EM>visible"</EM> because  including  a  header
+           file does not necessarily make all symbols in it visible (there are
+           ifdef's to consider).
+
+           For instance, in ncurses &lt;wchar.h&gt; <EM>may</EM> be included  if  the  proper
+           symbol  is defined, and if ncurses is configured for wide-character
+           support.  If the header  is  included,  its  symbols  may  be  made
+           visible.   That depends on the value used for <STRONG>_XOPEN_SOURCE</STRONG> feature
+           test macro.
+
+       <STRONG>o</STRONG>   X/Open Curses documents one required header,  in  a  special  case:
+           &lt;stdarg.h&gt;   before  &lt;curses.h&gt;  to  prototype  the  <STRONG>vw_printw</STRONG>  and
+           <STRONG>vw_scanw</STRONG> functions (as  well  as  the  obsolete  the  <STRONG>vwprintw</STRONG>  and
+           <STRONG>vwscanw</STRONG> functions).  Each of those uses a <STRONG>va_list</STRONG> parameter.
+
+           The  two  obsolete  functions  were  introduced in SVr3.  The other
+           functions were introduced  in  X/Open  Curses.   In  between,  SVr4
+           curses  provided  for  the  possibility  that  an application might
+           include either &lt;varargs.h&gt; or &lt;stdarg.h&gt;.  Initially, that was done
+           by  using  <STRONG>void*</STRONG>  for the <STRONG>va_list</STRONG> parameter.  Later, a special type
+           (defined in &lt;stdio.h&gt;) was introduced, to allow for compiler  type-
+           checking.  That special type is always available, because &lt;stdio.h&gt;
+           is always included by &lt;curses.h&gt;.
+
+           None of the X/Open Curses implementations require an application to
+           include  &lt;stdarg.h&gt;  before  &lt;curses.h&gt;  because  they  either have
+           allowed for a special type, or (like  ncurses)  include  &lt;stdarg.h&gt;
+           directly to provide a portable interface.

+       These functions are an extension to the curses library.  They permit an
+       application  to  dynamically  allocate   a   color   pair   using   the
+       foreground/background  colors  rather  than  assign  a fixed color pair
+       number, and return an unused pair to the pool.
+
+       The number of colors may be related to the  number  of  possible  color
+       pairs for a given terminal, or it may not:
+
+       <STRONG>o</STRONG>   While  almost  all  terminals  allow  setting  the color <EM>attributes</EM>
+           independently, it is unlikely that  your  terminal  allows  you  to
+           modify  the  attributes of a given character cell without rewriting
+           it.  That is, the foreground and background colors are applied as a
+           pair.
+
+       <STRONG>o</STRONG>   Color  pairs  are  the  curses  library's  way  of managing a color
+           palette on a terminal.  If the library does not keep track  of  the
+           <EM>combinations</EM> of colors which are displayed, it will be inefficient.
+
+       <STRONG>o</STRONG>   For   simple  terminal  emulators  with  only  a  few  dozen  color
+           combinations, it  is  convenient  to  use  the  maximum  number  of
+           combinations as the limit on color pairs:
+
+               <STRONG>COLORS</STRONG> <EM>*</EM> <STRONG>COLORS</STRONG>
+
+       <STRONG>o</STRONG>   Terminals  which support <EM>default</EM> <EM>colors</EM> distinct from "ANSI colors"
+           add to the possible combinations, producing this total:
+
+               <EM>(</EM> <STRONG>COLORS</STRONG> <EM>+</EM> <EM>1</EM> <EM>)</EM> <EM>*</EM> <EM>(</EM> <STRONG>COLORS</STRONG> <EM>+</EM> <EM>1</EM> <EM>)</EM>
+
+       <STRONG>o</STRONG>   An application might use up to a few dozen color pairs to implement
+           a predefined color scheme.
+
+           Beyond  that lies in the realm of programs using the foreground and
+           background colors  for  "ASCII  art"  (or  some  other  non-textual
+           application).
+
+           Also beyond those few dozen pairs, the required size for a table to
+           represent the combinations grows rapidly with an increasing  number
+           of colors.
+
+           These  functions allow a developer to let the screen library manage
+           color pairs.
+
+
+</PRE><H3><a name="h3-alloc_pair">alloc_pair</a></H3><PRE>
+       The  <STRONG>alloc_pair</STRONG>  function  accepts  parameters   for   foreground   and
+       background  color,  and  checks  if  that  color combination is already
+       associated with a color pair.
+
+       <STRONG>o</STRONG>   If the combination already exists, <STRONG>alloc_pair</STRONG> returns the  existing
+           pair.
+
+       <STRONG>o</STRONG>   If the combination does not exist, <STRONG>alloc_pair</STRONG> allocates a new color
+           pair and returns that.
+
+       <STRONG>o</STRONG>   If the table  fills  up,  <STRONG>alloc_pair</STRONG>  discards  the  least-recently
+           allocated entry using <STRONG>free_pair</STRONG> and allocates a new color pair.
+
+       All  of  the  color  pairs are allocated from a table of possible color
+       pairs.  The size of the table  is  determined  by  the  terminfo  <STRONG>pairs</STRONG>
+       capability.   The  table  is  shared with <STRONG>init_pair</STRONG>; in fact <STRONG>alloc_pair</STRONG>
+       calls <STRONG>init_pair</STRONG> after updating the ncurses library's fast index to  the
+       colors versus color pairs.
+
+
+</PRE><H3><a name="h3-find_pair">find_pair</a></H3><PRE>
+       The <STRONG>find_pair</STRONG> function accepts parameters for foreground and background
+       color, and checks if that color combination is already associated  with
+       a  color  pair,  returning  the  pair  number if it has been allocated.
+       Otherwise it returns -1.
+
+
+</PRE><H3><a name="h3-free_pair">free_pair</a></H3><PRE>
+       Marks the given color pair as unused, i.e., like color pair 0.
+

+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       The <STRONG>alloc_pair</STRONG> function returns a color pair  number  in  the  range  1
+       through  <STRONG>COLOR_PAIRS</STRONG>-1, unless it encounters an error updating its fast
+       index to the color pair values, preventing it from allocating  a  color
+       pair.  In that case, it returns -1.
+
+       The  <STRONG>find_pair</STRONG>  function returns a color pair number if the given color
+       combination has been associated with a color pair, or -1 if not.
+
+       Likewise, <STRONG>free_pair</STRONG> returns <STRONG>OK</STRONG> unless it encounters an  error  updating
+       the fast index or if no such color pair is in use.

+       Panels  are  <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG> windows with the added feature of depth.  Panel
+       functions allow the use  of  stacked  windows  and  ensure  the  proper
+       portions  of  each  window  and  the curses <STRONG>stdscr</STRONG> window are hidden or
+       displayed when panels are added, moved, modified or removed.   The  set
+       of  currently visible panels is the stack of panels.  The <STRONG>stdscr</STRONG> window
+       is beneath all panels, and is not considered part of the stack.
+
+       A window is associated with every panel.  The panel routines enable you
+       to  create, move, hide, and show panels, as well as position a panel at
+       any desired location in the stack.
+
+       Panel routines are a functional layer added to  <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>,  make  only
+       high-level curses calls, and work anywhere terminfo curses does.

+       Reasonable care has been taken  to   ensure   compatibility  with   the
+       native   panel  facility introduced in System V (inspection of the SVr4
+       manual pages suggests the programming  interface  is  unchanged).   The
+       <STRONG>PANEL</STRONG>   data  structures  are  merely   similar.   The   programmer  is
+       cautioned not to directly use <STRONG>PANEL</STRONG> fields.
+
+       The  functions  <STRONG>show_panel</STRONG>  and  <STRONG>top_panel</STRONG>  are   identical   in   this
+       implementation,  and work equally well with displayed or hidden panels.
+       In the native System  V  implementation,  <STRONG>show_panel</STRONG>  is  intended  for
+       making  a  hidden panel visible (at the top of the stack) and <STRONG>top_panel</STRONG>
+       is intended for making an already-visible panel move to the top of  the
+       stack.   You  are  cautioned  to  use  the  correct  function to ensure
+       compatibility with native panel libraries.
+
+

+       In your library list, libpanel.a should be  before  libncurses.a;  that
+       is, you should say "-lpanel -lncurses", not the other way around (which
+       would give a link-error with static libraries).
+

+       The panel facility was documented in SVr4.2 in <EM>Character</EM> <EM>User</EM> <EM>Interface</EM>
+       <EM>Programming</EM> <EM>(UNIX</EM> <EM>SVR4.2)</EM>.
+
+       It is not part of X/Open Curses.
+
+       A few implementations exist:
+
+       <STRONG>o</STRONG>   Systems  based  on  SVr4  source  code, e.g., Solaris, provide this
+           library.
+
+       <STRONG>o</STRONG>   <STRONG>ncurses</STRONG> (since version 0.6 in 1993) and <STRONG>PDCurses</STRONG> (since version 2.2
+           in 1995) provide a panel library whose common ancestor was a public
+           domain implementation by Warren Tucker published  in  <EM>u386mon</EM>  2.20
+           (1990).
+
+           According  to  Tucker, the SystemV panel library was first released
+           in SVr3.2 (1988), and his implementation  helped  with  a  port  to
+           SVr3.1 (1987).
+
+           Several  developers have improved each of these; they are no longer
+           the same as Tucker's implementation.
+
+       <STRONG>o</STRONG>   NetBSD 8 (2018) has a panel library  begun  by  Valery  Ushakov  in
+           2015.  This is based on the AT&amp;T documentation.

+       programs running in  an  X  Window  terminal  (e.g.,  xterm)  when  the
+       terminal's screen size is changed by the user:
+
+       <STRONG>o</STRONG>   Curses  windows  cannot extend outside the screen.  If the terminal
+           is shrunk, curses windows must be shrunk to fit.
+
+       <STRONG>o</STRONG>   If the terminal is stretched, rows and/or columns can be  added  to
+           existing  windows.   The  added  cells  should  match  the  current
+           attributes of the windows.
+
+       If the calling program has not set up a handler for  <STRONG>SIGWINCH</STRONG>  when  it
+       initializes  <STRONG>ncurses</STRONG>  (e.g.,  using  <STRONG><A HREF="curs_initscr.3x.html">initscr(3x)</A></STRONG>  or <STRONG><A HREF="curs_initscr.3x.html">newterm(3x)</A></STRONG>), then
+       <STRONG>ncurses</STRONG> sets a handler for <STRONG>SIGWINCH</STRONG> which notifies the library  when  a
+       window-size   event   has   occurred.   The  library  checks  for  this
+       notification
+
+       <STRONG>o</STRONG>   when reading input data,
+
+       <STRONG>o</STRONG>   when implicitly resuming program mode (e.g., between <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG> and
+           <STRONG><A HREF="curs_refresh.3x.html">wrefresh(3x)</A></STRONG>), and
+
+       <STRONG>o</STRONG>   when explicitly resuming program mode in <STRONG><A HREF="curs_terminfo.3x.html">restartterm(3x)</A></STRONG>.
+
+       When the library has found that the terminal's window-size has changed,
+       it calls <STRONG>resizeterm</STRONG> to update its data structures.
+
+       An application which establishes its  own  <STRONG>SIGWINCH</STRONG>  handler  can  call
+       <STRONG>resizeterm</STRONG>,  but  in  that case, the library will not see <STRONG>SIGWINCH</STRONG>, and
+       proper layout will rely upon the application.

+       The function <STRONG>resizeterm</STRONG> resizes the standard and current windows (i.e.,
+       <STRONG>stdscr</STRONG>  and  <STRONG>curscr</STRONG>)  to  the  specified  dimensions, and adjusts other
+       bookkeeping data used by the <STRONG>ncurses</STRONG> library  that  record  the  window
+       dimensions such as the <STRONG>LINES</STRONG> and <STRONG>COLS</STRONG> variables.
+
+
+</PRE><H3><a name="h3-resize_term">resize_term</a></H3><PRE>
+       Most  of  the  work  for  <STRONG>resizeterm</STRONG>  is  done  by  the  inner function
+       <STRONG>resize_term</STRONG>.  The outer function <STRONG>resizeterm</STRONG> adds  bookkeeping  for  the
+       <STRONG>SIGWINCH</STRONG>  handler,  as  well  as  repainting  the  soft-key  area  (see
+       <STRONG><A HREF="curs_slk.3x.html">slk_touch(3x)</A></STRONG>).
+
+       The <STRONG>resize_term</STRONG> function attempts to resize all  windows.   This  helps
+       with simple applications.  However:
+
+       <STRONG>o</STRONG>   It is not possible to automatically resize pads.
+
+       <STRONG>o</STRONG>   Applications  which  have  complicated  layouts  should  check  for
+           <STRONG>KEY_RESIZE</STRONG> returned from <STRONG>wgetch</STRONG>, and  adjust  their  layout,  e.g.,
+           using <STRONG>wresize</STRONG> and <STRONG>mvwin</STRONG>, or by recreating the windows.
+
+       When  resizing  windows,  <STRONG>resize_term</STRONG>  recursively  adjusts subwindows,
+       keeping them within the updated parent window's limits.  If a top-level
+       window  happens  to extend to the screen's limits, then on resizing the
+       window, <STRONG>resize_term</STRONG> will keep the window extending to the corresponding
+       limit, regardless of whether the screen has shrunk or grown.
+
+
+</PRE><H3><a name="h3-is_term_resized">is_term_resized</a></H3><PRE>
+       A support function <STRONG>is_term_resized</STRONG> is provided so that applications can
+       check if the <STRONG>resize_term</STRONG> function would modify the  window  structures.
+       It returns <STRONG>TRUE</STRONG> if the windows would be modified, and <STRONG>FALSE</STRONG> otherwise.
+
+
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+       Except  as  noted,  these functions return the integer <STRONG>ERR</STRONG> upon failure
+       and <STRONG>OK</STRONG> on success.  They will fail if either of the dimensions are less
+       than  or  equal  to  zero,  or  if an error occurs while (re)allocating
+       memory for the windows.
+
+
+</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
+       While these functions are intended to  be  used  to  support  a  signal
+       handler  (i.e.,  for  <STRONG>SIGWINCH</STRONG>), care should be taken to avoid invoking
+       them in a context where <STRONG>malloc</STRONG> or <STRONG>realloc</STRONG> may  have  been  interrupted,
+       since it uses those functions.
+
+       If ncurses is configured to supply its own <STRONG>SIGWINCH</STRONG> handler,
+
+       <STRONG>o</STRONG>   on receipt of a <STRONG>SIGWINCH</STRONG>, the handler sets a flag
+
+       <STRONG>o</STRONG>   which is tested in <STRONG><A HREF="curs_getch.3x.html">wgetch(3x)</A></STRONG>, <STRONG><A HREF="curs_refresh.3x.html">doupdate(3x)</A></STRONG> and <STRONG><A HREF="curs_terminfo.3x.html">restartterm(3x)</A></STRONG>,
+
+       <STRONG>o</STRONG>   in turn, calling the <STRONG>resizeterm</STRONG> function,
+
+       <STRONG>o</STRONG>   which <STRONG>ungetch</STRONG>'s a <STRONG>KEY_RESIZE</STRONG> which will be read on the next call to
+           <STRONG>wgetch</STRONG>.
+
+           The <STRONG>KEY_RESIZE</STRONG> alerts an  application  that  the  screen  size  has
+           changed,  and  that it should repaint special features such as pads
+           that cannot be done automatically.
+
+           Calling <STRONG>resizeterm</STRONG> or <STRONG>resize_term</STRONG> directly from a signal handler is
+           unsafe.   This  indirect  method  is  used to provide a safe way to
+           resize the ncurses data structures.
+
+       If the environment variables <STRONG>LINES</STRONG> or <STRONG>COLUMNS</STRONG> are set,  this  overrides
+       the  library's  use  of  the  window  size  obtained from the operating
+       system.  Thus, even if a <STRONG>SIGWINCH</STRONG> is received, no  screen  size  change
+       may be recorded.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       It is possible to resize the screen with SVr4 curses, by
+
+       <STRONG>o</STRONG>   exiting curses with <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG> and

+       The  curses library provides applications with the ability to write the
+       contents of a window to an external file using <STRONG>scr_dump</STRONG> or <STRONG>putwin</STRONG>,  and
+       read it back using <STRONG>scr_restore</STRONG> or <STRONG>getwin</STRONG>.
+
+       The  <STRONG>putwin</STRONG>  and  <STRONG>getwin</STRONG>  functions  do  the  work;  while <STRONG>scr_dump</STRONG> and
+       <STRONG>scr_restore</STRONG> conveniently save  and  restore  the  whole  screen,  i.e.,
+       <STRONG>stdscr</STRONG>.
+
+
+</PRE><H3><a name="h3-ncurses6">ncurses6</a></H3><PRE>
+       A  longstanding implementation of screen-dump was revised with ncurses6
+       to remedy problems with the earlier approach:
+
+       <STRONG>o</STRONG>   A "magic number" is written to the  beginning  of  the  dump  file,
+           allowing  applications  (such  as <STRONG>file(1)</STRONG>) to recognize curses dump
+           files.
+
+           Because ncurses6 uses a new  format,  that  requires  a  new  magic
+           number  was  unused  by other applications.  This 16-bit number was
+           unused:
+
+               0x8888 (octal "\210\210")
+
+           but to be more certain, this 32-bit number was chosen:
+
+               0x88888888 (octal "\210\210\210\210")
+
+           This is the pattern  submitted  to  the  maintainers  of  the  <STRONG>file</STRONG>
+           program:
+
+               #
+               # ncurses5 (and before) did not use a magic number,
+               # making screen dumps "data".
+               #
+               # ncurses6 (2015) uses this format, ignoring byte-order
+               0    string    \210\210\210\210ncurses    ncurses6 screen image
+               #
+
+       <STRONG>o</STRONG>   The screen dumps are written in textual form, so that internal data
+           sizes are not directly related to the dump-format, and enabling the
+           library  to  read  dumps  from  either  narrow-  or wide-character-
+           configurations.
+
+           The  <EM>narrow</EM>  library  configuration  holds  characters  and   video
+           attributes  in  a  32-bit  <STRONG>chtype</STRONG>, while the <EM>wide-character</EM> library
+           stores this information in the <STRONG>cchar_t</STRONG>  structure,  which  is  much
+           larger than 32-bits.
+
+       <STRONG>o</STRONG>   It  is  possible  to  read  a  screen  dump  into a terminal with a
+           different screen-size, because the library truncates or  fills  the
+           screen as necessary.
+
+       <STRONG>o</STRONG>   The ncurses6 <STRONG>getwin</STRONG> reads the legacy screen dumps from ncurses5.
+
+
+</PRE><H3><a name="h3-ncurses5-_legacy_">ncurses5 (legacy)</a></H3><PRE>
+       The screen-dump feature was added to ncurses in June 1995.  While there
+       were fixes and improvements in succeeding years, the basic  scheme  was
+       unchanged:
+
+       <STRONG>o</STRONG>   The <STRONG>WINDOW</STRONG> structure was written in binary form.
+
+       <STRONG>o</STRONG>   The <STRONG>WINDOW</STRONG> structure refers to lines of data, which were written as
+           an array of binary data following the <STRONG>WINDOW</STRONG>.
+
+       <STRONG>o</STRONG>   When <STRONG>getwin</STRONG> restored the window, it would  keep  track  of  offsets
+           into  the  array of line-data and adjust the <STRONG>WINDOW</STRONG> structure which
+           was read back into memory.
+
+       This is similar to Unix SystemV, but does not write a "magic number" to
+       identify the file format.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       There  is  no  standard  format for <STRONG>putwin</STRONG>.  This section gives a brief
+       description of the existing formats.
+
+
+</PRE><H3><a name="h3-X_Open-Curses">X/Open Curses</a></H3><PRE>
+       Refer to <EM>X/Open</EM> <EM>Curses,</EM> <EM>Issue</EM> <EM>7</EM> (2009).
+
+       X/Open's documentation for <EM>enhanced</EM> <EM>curses</EM> says only:
+
+          The <STRONG>getwin(</STRONG> <STRONG>)</STRONG> function reads window-related data stored in the  file
+          by  <EM>putwin(</EM> <EM>)</EM>.   The  function  then  creates  and initializes a new
+          window using that data.
+
+          The <STRONG>putwin(</STRONG> <STRONG>)</STRONG> function writes all data associated with <EM>win</EM> into  the
+          <STRONG>stdio(3)</STRONG>  stream to which <EM>filep</EM> points, using an <STRONG>unspecified</STRONG> <STRONG>format</STRONG>.
+          This information can be retrieved later using <STRONG>getwin(</STRONG> <STRONG>)</STRONG>.
+
+       In the mid-1990s when the X/Open Curses  document  was  written,  there
+       were  still  systems  using older, less capable curses libraries (aside
+       from the BSD curses library which was not relevant to X/Open because it
+       did not meet the criteria for <EM>base</EM> <EM>curses</EM>).  The document explained the
+       term "enhanced" as follows:
+
+          <STRONG>o</STRONG>   Shading is used to identify  <EM>X/Open</EM>  <EM>Enhanced</EM>  <EM>Curses</EM>  material,
+              relating to interfaces included to provide enhanced capabilities
+              for applications originally written to be  compiled  on  systems
+              based  on  the  UNIX  operating system.  Therefore, the features
+              described may not be present on systems that conform to <STRONG>XPG4</STRONG>  <STRONG>or</STRONG>
+              <STRONG>to</STRONG>  <STRONG>earlier</STRONG>  <STRONG>XPG</STRONG>  <STRONG>releases</STRONG>.   The  relevant  reference pages may
+              provide additional or more specific portability  warnings  about
+              use of the material.
+
+       In  the foregoing, emphasis was added to <STRONG>unspecified</STRONG> <STRONG>format</STRONG> and to <STRONG>XPG4</STRONG>
+       <STRONG>or</STRONG> <STRONG>to</STRONG> <STRONG>earlier</STRONG> <STRONG>XPG</STRONG> <STRONG>releases</STRONG>, for clarity.
+
+
+</PRE><H3><a name="h3-Unix-SystemV">Unix SystemV</a></H3><PRE>
+       Unix SystemV curses identified the file  format  by  writing  a  "magic
+       number" at the beginning of the dump.  The <STRONG>WINDOW</STRONG> data and the lines of
+       text follow, all in binary form.
+
+       The Solaris curses source has these definitions:
+
+           /* terminfo magic number */
+           #define MAGNUM  0432
+
+           /* curses screen dump magic number */
+           #define SVR2_DUMP_MAGIC_NUMBER  0433
+           #define SVR3_DUMP_MAGIC_NUMBER  0434
+
+       That is, the feature was likely introduced in SVr2 (1984), and improved
+       in SVr3 (1987).  The Solaris curses source has no magic number for SVr4
+       (1989).  Other operating systems (AIX and  HPUX)  use  a  magic  number
+       which would correspond to this definition:
+
+           /* curses screen dump magic number */
+           #define SVR4_DUMP_MAGIC_NUMBER  0435
+
+       That  octal number in bytes is 001, 035.  Because most Unix vendors use
+       big-endian hardware, the magic number is written  with  the  high-order
+       byte first, e.g.,
+
+            01 35
+
+       After  the magic number, the <STRONG>WINDOW</STRONG> structure and line-data are written
+       in binary format.  While the magic number used by the Unix systems  can
+       be seen using <STRONG>od(1)</STRONG>, none of the Unix systems documents the format used
+       for screen-dumps.
+

+       produced dumps of different size (all  on  64-bit  hardware,  on  40x80

+       As  noted  above,  Solaris  curses has no magic number corresponding to
+       SVr4 curses.  This is odd since Solaris was the first operating  system
+       to pass the SVr4 guidelines.  Solaris has two versions of curses:
+
+       <STRONG>o</STRONG>   The default curses library uses the SVr3 magic number.
+
+       <STRONG>o</STRONG>   There  is  an  alternate  curses library in <STRONG>/usr/xpg4</STRONG>.  This uses a
+           textual format with no magic number.
+
+           According to the copyright notice, the <EM>xpg4</EM> Solaris curses  library
+           was developed by MKS (Mortice Kern Systems) from 1990 to 1995.
+
+           Like  ncurses6,  there  is  a  file-header with parameters.  Unlike
+           ncurses6, the contents of the window are  written  piecemeal,  with
+           coordinates  and  attributes  for  each  chunk  of text rather than
+           writing the whole window from top to bottom.

+       PDCurses added support for screen dumps in version  2.7  (2005).   Like
+       Unix  SystemV  and  ncurses5, it writes the <STRONG>WINDOW</STRONG> structure in binary,
+       but begins the file with its three-byte identifier "PDC", followed by a
+       one-byte version, e.g.,
+
+                "PDC\001"
+
+

+       As  of  April  2017,  NetBSD  curses  does  not  support  <STRONG>scr_dump</STRONG>  and
+       <STRONG>scr_restore</STRONG> (or <STRONG>scr_init</STRONG>, <STRONG>scr_set</STRONG>), although it has <STRONG>putwin</STRONG> and <STRONG>getwin</STRONG>.
+
+       Like ncurses5, NetBSD <STRONG>putwin</STRONG> does not identify its dumps with a  useful
+       magic number.  It writes
+
+       <STRONG>o</STRONG>   the curses shared library major and minor versions as the first two
+           bytes (e.g., 7 and 1),
+
+       <STRONG>o</STRONG>   followed by a binary dump of the <STRONG>WINDOW</STRONG>,
+
+       <STRONG>o</STRONG>   some data for wide-characters referenced by the  <STRONG>WINDOW</STRONG>  structure,
+           and
+
+       <STRONG>o</STRONG>   finally, lines as done by other implementations.

+       Given  a  simple  program  which writes text to the screen (and for the

+
+       <STRONG>o</STRONG>   The actual color pair values are not written to the file.
+
+       <STRONG>o</STRONG>   All  characters  are  shown  in  printable form; spaces are "\s" to
+           ensure they are not overlooked.
+
+       <STRONG>o</STRONG>   Attributes are written in escaped curly  braces,  e.g.,  "\{BOLD}",
+           and may include a color-pair (C1 or C2 in this example).
+
+       <STRONG>o</STRONG>   The  parameters  in  the  header  are  written out only if they are
+           nonzero.  When reading back, order does not matter.

+       The  <STRONG>tabs</STRONG> program clears and sets tab-stops on the terminal.  This uses
+       the terminfo <STRONG>clear_all_tabs</STRONG> and <STRONG>set_tab</STRONG>  capabilities.   If  either  is
+       absent,  <STRONG>tabs</STRONG> is unable to clear/set tab-stops.  The terminal should be
+       configured to use hard tabs, e.g.,
+
+           stty tab0
+
+       Like <STRONG><A HREF="clear.1.html">clear(1)</A></STRONG>, <STRONG>tabs</STRONG> writes to the standard output.   You  can  redirect
+       the  standard  output  to  a  file  (which  prevents <STRONG>tabs</STRONG> from actually
+       changing the tabstops), and later <STRONG>cat</STRONG> the file to the  screen,  setting
+       tabstops at that point.
+
+       These   are   hardware   tabs,  which  cannot  be  queried  rapidly  by
+       applications running in the terminal, if  at  all.   Curses  and  other
+       full-screen  applications  may  use  hardware  tabs in optimizing their
+       output to the terminal.  If  the  hardware  tabstops  differ  from  the
+       information  in  the  terminal  database,  the result is unpredictable.
+       Before running curses programs, you should either  reset  tab-stops  to
+       the standard interval
+
+           tabs -8
+
+       or  use the <STRONG>reset</STRONG> program, since the normal initialization sequences do
+       not ensure that tab-stops are reset.

+       A  few  terminals  provide the capability for changing their left/right
+       margins.  The tabs program has an option to use this feature:
+
+       <STRONG>+m</STRONG> <EM>margin</EM>
+            The  effect  depends  on  whether  the  terminal  has  the  margin
+            capabilities:
+
+            <STRONG>o</STRONG>   If  the  terminal provides the capability for setting the left
+                margin, tabs uses this, and adjusts the  available  width  for
+                tab-stops.
+
+            <STRONG>o</STRONG>   If the terminal does not provide the margin capabilities, tabs
+                imitates the effect, putting the tab stops at the  appropriate
+                place  on  each  line.   The  terminal's  left-margin  is  not
+                modified.
+
+            If the <EM>margin</EM> parameter is omitted, the default is 10.  Use <STRONG>+m0</STRONG> to
+            reset  the  left  margin, i.e., to the left edge of the terminal's
+            display.  Before setting a left-margin, tabs resets the margin  to
+            reduce  problems which might arise on moving the cursor before the
+            current left-margin.
+
+       When setting or resetting the left-margin, tabs may  reset  the  right-
+       margin.

+       (POSIX.1-2008) describes a <STRONG>tabs</STRONG> utility.  However
+
+       <STRONG>o</STRONG>   This standard describes a <STRONG>+m</STRONG> option,  to  set  a  terminal's  left-
+           margin.   Very  few of the entries in the terminal database provide
+           the  <STRONG>smgl</STRONG>   (<STRONG>set_left_margin</STRONG>)   or   <STRONG>smglp</STRONG>   (<STRONG>set_left_margin_parm</STRONG>)
+           capability needed to support the feature.
+
+       <STRONG>o</STRONG>   There  is no counterpart in X/Open Curses Issue 7 for this utility,
+           unlike <STRONG><A HREF="tput.1.html">tput(1)</A></STRONG>.
+
+       The <STRONG>-d</STRONG> (debug) and <STRONG>-n</STRONG> (no-op) options are extensions  not  provided  by
+       other implementations.
+
+       A  <STRONG>tabs</STRONG>  utility  appeared in PWB/Unix 1.0 (1977).  There was a reduced
+       version of the <STRONG>tabs</STRONG> utility in Unix 7th edition  and  in  3BSD  (1979).
+       The  latter supported a single "-n" option (to cause the first tab stop
+       to be set on the left margin).  That option is not documented by POSIX.
+
+       The PWB/Unix <STRONG>tabs</STRONG> utility, which was included  in  System  III  (1980),
+       used  built-in  tables  rather than the terminal database, to support a
+       half-dozen hardcopy terminal (printer) types.   It  also  had  built-in
+       logic  to support the left-margin, as well as a feature for copying the
+       tab settings from a file.
+
+       Later versions of Unix, e.g., SVr4,  added  support  for  the  terminal
+       database,  but  kept the tables to support the printers.  In an earlier
+       development effort, the tab-stop initialization provided by <STRONG>tset</STRONG> (1982)
+       and incorporated into <STRONG>tput</STRONG> uses the terminal database,
+
+       The  <STRONG>+m</STRONG>  option  was  documented  in  the  Base  Specifications Issue 5
+       (Unix98,  1997),  and  omitted  in  Issue  6  (Unix03,  2004)   without
+       documenting   the   rationale,  though  an  introductory  comment  <EM>"and</EM>
+       <EM>optionally</EM> <EM>adjusts</EM> <EM>the</EM> <EM>margin"</EM> remains, overlooked in the removal.  The
+       documented  <STRONG>tabs</STRONG>  utility  in  Issues  6 and later has no mechanism for
+       setting margins.  The <STRONG>+m</STRONG> option in this implementation differs from the
+       feature  in  SVr4  by  using terminal capabilities rather than built-in
+       tables.
+
+       POSIX documents no limits on the number of  tab  stops.   Documentation
+       for other implementations states that there is a limit on the number of
+       tab stops (e.g., 20 in PWB/Unix's <STRONG>tabs</STRONG> utility).  While some  terminals
+       may  not  accept  an arbitrary number of tab stops, this implementation
+       will attempt to set tab stops up to the right margin of the screen,  if
+       the given list happens to be that long.
+
+       The  <EM>Rationale</EM> section of the POSIX documentation goes into some detail
+       about the ways the committee considered redesigning the <STRONG>tabs</STRONG>  and  <STRONG>tput</STRONG>
+       utilities, without proposing an improved solution.  It comments that
+
+            no  known  historical  version  of tabs supports the capability of
+            setting arbitrary tab stops.
+
+       However,  the  <EM>Explicit</EM>  <EM>Lists</EM>  described  in  this  manual  page  were
+       implemented  in  PWB/Unix.   Those  provide  the  capability of setting
+       abitrary tab stops.

+       Compiled   terminfo   descriptions   are  placed  under  the  directory
+       <STRONG>/usr/share/terminfo</STRONG>.  Two configurations are supported  (when  building
+       the <STRONG>ncurses</STRONG> libraries):
+
+       <STRONG>directory</STRONG> <STRONG>tree</STRONG>
+            A two-level scheme is used to avoid a linear search of a huge UNIX
+            system directory: <STRONG>/usr/share/terminfo/c/name</STRONG>  where  <EM>name</EM>  is  the
+            name of the terminal, and <EM>c</EM> is the first character of <EM>name</EM>.  Thus,
+            <EM>act4</EM>  can  be  found  in  the   file   <STRONG>/usr/share/terminfo/a/act4</STRONG>.
+            Synonyms  for  the same terminal are implemented by multiple links
+            to the same compiled file.
+
+       <STRONG>hashed</STRONG> <STRONG>database</STRONG>
+            Using Berkeley database, two types  of  records  are  stored:  the
+            terminfo  data  in  the  same format as stored in a directory tree
+            with the terminfo's primary name as a key, and records  containing
+            only aliases pointing to the primary name.
+
+            If  built  to  write  hashed  databases,  <STRONG>ncurses</STRONG>  can  still read
+            terminfo databases organized as a directory tree, but cannot write
+            entries  into  the  directory  tree.   It  can  write (or rewrite)
+            entries in the hashed database.
+
+            <STRONG>ncurses</STRONG>  distinguishes  the  two  cases  in   the   TERMINFO   and
+            TERMINFO_DIRS  environment  variable  by assuming a directory tree
+            for entries that correspond to an existing directory,  and  hashed
+            database otherwise.
+
+
+</PRE><H3><a name="h3-LEGACY-STORAGE-FORMAT">LEGACY STORAGE FORMAT</a></H3><PRE>
+       The format has been chosen so that it will be the same on all hardware.
+       An 8 or more bit  byte  is  assumed,  but  no  assumptions  about  byte
+       ordering or sign extension are made.
+
+       The  compiled  file  is  created  with the <STRONG>tic</STRONG> program, and read by the
+       routine <STRONG><A HREF="curs_terminfo.3x.html">setupterm(3x)</A></STRONG>.  The file is divided into six parts:
+
+            a) <EM>header</EM>,
+
+            b) <EM>terminal</EM> <EM>names</EM>,
+
+            c) <EM>boolean</EM> <EM>flags</EM>,
+
+            d) <EM>numbers</EM>,
+
+            e) <EM>strings</EM>, and
+
+            f) <EM>string</EM> <EM>table</EM>.
+
+       The <EM>header</EM> section begins the file.  This section  contains  six  short
+       integers in the format described below.  These integers are
+
+            (1) the <EM>magic</EM> <EM>number</EM> (octal 0432);
+
+            (2) the size, in bytes, of the <EM>terminal</EM> <EM>names</EM> section;
+
+            (3) the number of bytes in the <EM>boolean</EM> <EM>flags</EM> section;
+
+            (4) the number of short integers in the <EM>numbers</EM> section;
+
+            (5) the number of offsets (short integers) in the <EM>strings</EM> section;
+
+            (6) the size, in bytes, of the <EM>string</EM> <EM>table</EM>.
+
+       The  capabilities  in  the <EM>boolean</EM> <EM>flags</EM>, <EM>numbers</EM>, and <EM>strings</EM> sections
+       are in the same order as the file &lt;term.h&gt;.
+
+       Short integers are signed, in the range  -32768  to  32767.   They  are
+       stored  as  two  8-bit  bytes.   The  first  byte  contains  the  least
+       significant 8 bits of the value, and the second byte contains the  most
+       significant 8 bits.  (Thus, the value represented is 256*second+first.)
+       This format corresponds to the hardware of the VAX and PDP-11 (that is,
+       little-endian  machines).   Machines  where this does not correspond to
+       the hardware must read the  integers  as  two  bytes  and  compute  the
+       little-endian value.
+
+       Numbers  in  a  terminal  description,  whether they are entries in the
+       <EM>numbers</EM> or <EM>strings</EM> table, are positive  integers.   Boolean  flags  are
+       treated  as  positive  one-byte integers.  In each case, those positive
+       integers represent a terminal capability.  The  terminal  compiler  tic
+       uses  negative  integers  to handle the cases where a capability is not
+       available:
+
+       <STRONG>o</STRONG>   If a capability is absent from this terminal, tic stores  a  -1  in
+           the corresponding table.
+
+           The integer value -1 is represented by two bytes 0377, 0377.
+           Absent boolean values are represented by the byte 0 (false).
+
+       <STRONG>o</STRONG>   If  a capability has been canceled from this terminal, tic stores a
+           -2 in the corresponding table.
+
+           The integer value -2 is represented by two bytes 0377, 0376.
+           The boolean value -2 is represented by the byte 0376.
+
+       <STRONG>o</STRONG>   Other negative values are illegal.
+
+       The <EM>terminal</EM> <EM>names</EM> section comes after the  <EM>header</EM>.   It  contains  the
+       first  line  of the terminfo description, listing the various names for
+       the terminal, separated by  the  "|"  character.   The  <EM>terminal</EM>  <EM>names</EM>
+       section is terminated with an ASCII NUL character.
+
+       The  <EM>boolean</EM>  <EM>flags</EM>  section  has  one  byte  for  each  flag.  Boolean
+       capabilities are either 1 or 0 (true or false) according to whether the
+       terminal supports the given capability or not.
+
+       Between  the  <EM>boolean</EM> <EM>flags</EM> section and the <EM>number</EM> section, a null byte
+       will be inserted, if necessary,  to  ensure  that  the  <EM>number</EM>  section
+       begins  on  an even byte This is a relic of the PDP-11's word-addressed
+       architecture, originally designed to avoid traps induced by  addressing
+       a  word  on  an odd byte boundary.  All short integers are aligned on a
+       short word boundary.
+
+       The <EM>numbers</EM> section is similar to  the  <EM>boolean</EM>  <EM>flags</EM>  section.   Each
+       capability  takes  up two bytes, and is stored as a little-endian short
+       integer.
+
+       The <EM>strings</EM> section is also similar.  Each capability is  stored  as  a
+       short integer.  The capability value is an index into the <EM>string</EM> <EM>table</EM>.
+
+       The <EM>string</EM> <EM>table</EM> is the last section.  It contains all of the values of
+       string capabilities referenced in the <EM>strings</EM> section.  Each string  is
+       null-terminated.  Special characters in ^X or \c notation are stored in
+       their interpreted  form,  not  the  printing  representation.   Padding
+       information  $&lt;nn&gt;  and  parameter  information %x are stored intact in
+       uninterpreted form.

+       The previous section describes the conventional terminfo binary format.
+       With  some  minor variations of the offsets (see PORTABILITY), the same
+       binary format is used in all modern UNIX systems.  Each system  uses  a
+       predefined set of boolean, number or string capabilities.
+
+       The <STRONG>ncurses</STRONG> libraries and applications support extended terminfo binary
+       format, allowing users to  define  capabilities  which  are  loaded  at
+       runtime.   This  extension  is made possible by using the fact that the
+       other implementations stop reading the terminfo  data  when  they  have
+       reached  the  end  of the size given in the header.  <STRONG>ncurses</STRONG> checks the
+       size, and if it exceeds that due to the predefined data,  continues  to
+       parse according to its own scheme.
+
+       First, it reads the extended header (5 short integers):
+
+            (1)  count of extended boolean capabilities
+
+            (2)  count of extended numeric capabilities
+
+            (3)  count of extended string capabilities
+
+            (4)  count of the items in extended string table
+
+            (5)  size of the extended string table in bytes
+
+       The  count-  and  size-values for the extended string table include the
+       extended capability <EM>names</EM> as well as extended capability <EM>values</EM>.
+
+       Using the counts and sizes, <STRONG>ncurses</STRONG> allocates arrays and reads data for
+       the extended capabilities in the same order as the header information.
+
+       The  extended  string  table  contains  values for string capabilities.
+       After the end of these values, it contains the names for  each  of  the
+       extended  capabilities  in  order,  e.g.,  booleans,  then  numbers and
+       finally strings.
+
+       Applications which manipulate terminal data  can  use  the  definitions
+       described  in  <STRONG><A HREF="term_variables.3x.html">term_variables(3x)</A></STRONG>  which  associate the long capability
+       names with members of a <STRONG>TERMTYPE</STRONG> structure.
+
+
+</PRE><H3><a name="h3-EXTENDED-NUMBER-FORMAT">EXTENDED NUMBER FORMAT</a></H3><PRE>
+       On occasion, 16-bit signed integers are not large enough.  With <STRONG>ncurses</STRONG>
+       6.1,  a new format was introduced by making a few changes to the legacy
+       format:
+
+       <STRONG>o</STRONG>   a different magic number (octal 01036)
+
+       <STRONG>o</STRONG>   changing the type for the <EM>number</EM> array from signed 16-bit  integers
+           to signed 32-bit integers.
+
+       To   maintain   compatibility,  the  library  presents  the  same  data
+       structures to direct users of the <STRONG>TERMTYPE</STRONG>  structure  as  in  previous
+       formats.   However,  that  cannot  provide  callers  with  the extended
+       numbers.   The  library  uses  a  similar  but  hidden  data  structure
+       <STRONG>TERMTYPE2</STRONG> to provide data for the terminfo functions.

+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+
+</PRE><H3><a name="h3-setupterm">setupterm</a></H3><PRE>
+       Note  that  it  is  possible for <STRONG>setupterm</STRONG> to expect a different set of
+       capabilities than  are  actually  present  in  the  file.   Either  the
+       database   may   have  been  updated  since  <STRONG>setupterm</STRONG>  was  recompiled
+       (resulting in extra unrecognized entries in the file)  or  the  program
+       may  have  been  recompiled more recently than the database was updated
+       (resulting in missing entries).  The routine <STRONG>setupterm</STRONG> must be prepared
+       for  both  possibilities  -  this  is  why  the  numbers  and sizes are
+       included.  Also, new capabilities must always be added at  the  end  of
+       the lists of boolean, number, and string capabilities.

+       X/Open  Curses  does  not  specify  a format for the terminfo database.
+       UNIX System V curses used a directory-tree of  binary  files,  one  per
+       terminal description.
+
+       Despite  the  consistent  use  of  little-endian  for  numbers  and the
+       otherwise  self-describing  format,  it  is  not  wise  to   count   on
+       portability   of   binary  terminfo  entries  between  commercial  UNIX
+       versions.  The problem is that there are at  least  three  versions  of
+       terminfo  (under  HP-UX,  AIX,  and OSF/1) which diverged from System V
+       terminfo after SVr1, and  have  added  extension  capabilities  to  the
+       string  table that (in the binary format) collide with System V and XSI
+       Curses extensions.  See <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for detailed discussion of terminfo
+       source compatibility issues.
+
+       This  implementation  is by default compatible with the binary terminfo
+       format used by Solaris curses, except in a few less-used details  where
+       it  was  found that the latter did not match X/Open Curses.  The format
+       used by the other Unix versions can be matched by building ncurses with
+       different configuration options.
+
+
+</PRE><H3><a name="h3-Magic-codes">Magic codes</a></H3><PRE>
+       The  magic  number  in a binary terminfo file is the first 16-bits (two
+       bytes).  Besides making it more reliable for the library to check  that
+       a  file  is  terminfo,  utilities such as <STRONG>file(1)</STRONG> also use that to tell
+       what the file-format is.  System V defined more than one magic  number,
+       with 0433, 0435 as screen-dumps (see <STRONG><A HREF="scr_dump.5.html">scr_dump(5)</A></STRONG>).  This implementation
+       uses 01036 as a continuation of that sequence,  but  with  a  different
+       high-order byte to avoid confusion.

+
+</PRE><H3><a name="h3-The-TERMTYPE-structure">The TERMTYPE structure</a></H3><PRE>
+       Direct  access  to  the  <STRONG>TERMTYPE</STRONG>  structure  is  provided  for  legacy

+       related  functions  described in <STRONG><A HREF="curs_terminfo.3x.html">curs_terminfo(3x)</A></STRONG> for reading terminal

+       A small number of terminal descriptions  use  uppercase  characters  in
+       their  names.   If  the  underlying  filesystem  ignores the difference
+       between  uppercase  and  lowercase,  <STRONG>ncurses</STRONG>  represents   the   "first
+       character"  of  the  terminal  name used as the intermediate level of a
+       directory tree in (two-character) hexadecimal form.

+       term - conventions for naming terminal types
+
+
+</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
+       The  environment variable <STRONG>TERM</STRONG> should normally contain the type name of
+       the terminal, console or  display-device  type  you  are  using.   This
+       information  is  critical  for  all screen-oriented programs, including
+       your editor and mailer.
+
+       A default <STRONG>TERM</STRONG> value  will  be  set  on  a  per-line  basis  by  either
+       <STRONG>/etc/inittab</STRONG>  (e.g.,  System-V-like  UNIXes) or <STRONG>/etc/ttys</STRONG> (BSD UNIXes).
+       This will nearly  always  suffice  for  workstation  and  microcomputer
+       consoles.
+
+       If  you  use a dialup line, the type of device attached to it may vary.
+       Older UNIX systems pre-set a very dumb terminal  type  like  "dumb"  or
+       "dialup"  on  dialup lines.  Newer ones may pre-set "vt100", reflecting
+       the prevalence of DEC VT100-compatible terminals and  personal-computer
+       emulators.
+
+       Modern  telnets pass your <STRONG>TERM</STRONG> environment variable from the local side
+       to the remote one.  There can be problems if  the  remote  terminfo  or
+       termcap  entry  for  your  type  is not compatible with yours, but this
+       situation is rare and  can  almost  always  be  avoided  by  explicitly
+       exporting  "vt100"  (assuming  you  are  in fact using a VT100-superset
+       console, terminal, or terminal emulator).
+
+       In any case, you are free to override the system <STRONG>TERM</STRONG> setting  to  your
+       taste in your shell profile.  The <STRONG><A HREF="tset.1.html">tset(1)</A></STRONG> utility may be of assistance;
+       you can give it a set of rules for deducing or  requesting  a  terminal
+       type based on the tty device and baud rate.
+
+       Setting  your  own  <STRONG>TERM</STRONG> value may also be useful if you have created a
+       custom entry incorporating options (such as  visual  bell  or  reverse-
+       video)  which  you  wish  to  override the system default type for your
+       line.
+
+       Terminal type descriptions are  stored  as  files  of  capability  data
+       underneath /usr/share/terminfo.  To browse a list of all terminal names
+       recognized by the system, do
+
+            toe | more
+
+       from your shell.   These  capability  files  are  in  a  binary  format
+       optimized for retrieval speed (unlike the old text-based <STRONG>termcap</STRONG> format
+       they replace); to examine  an  entry,  you  must  use  the  <STRONG><A HREF="infocmp.1m.html">infocmp(1m)</A></STRONG>
+       command.  Invoke it as follows:
+
+            infocmp <EM>entry</EM><STRONG>_</STRONG><EM>name</EM>
+
+       where  <EM>entry</EM><STRONG>_</STRONG><EM>name</EM>  is the name of the type you wish to examine (and the
+       name of its capability file  the  subdirectory  of  /usr/share/terminfo
+       named  for  its first letter).  This command dumps a capability file in
+       the text format described by <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.
+
+       The first line of a <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> description gives the  names  by  which
+       terminfo  knows a terminal, separated by "|" (pipe-bar) characters with
+       the last name field terminated by a comma.  The first name field is the
+       type's <EM>primary</EM> <EM>name</EM>, and is the one to use when setting <STRONG>TERM</STRONG>.  The last
+       name field (if distinct from the first) is actually  a  description  of
+       the  terminal  type  (it  may contain blanks; the others must be single
+       words).  Name fields between  the  first  and  last  (if  present)  are
+       aliases  for  the  terminal,  usually  historical  names  retained  for
+       compatibility.
+
+       There are some conventions for how to  choose  terminal  primary  names
+       that  help  keep  them  informative and unique.  Here is a step-by-step
+       guide to naming terminals that also explains how to parse them:
+
+       First, choose a root name.  The  root  will  consist  of  a  lower-case
+       letter  followed by up to seven lower-case letters or digits.  You need
+       to avoid using punctuation characters in root names, because  they  are
+       used and interpreted as filenames and shell meta-characters (such as !,
+       $, *, ?, etc.) embedded in them may cause odd and  unhelpful  behavior.
+       The  slash  (/),  or  any  other  character  that may be interpreted by
+       anyone's file system (\, $, [, ]), is especially dangerous (terminfo is
+       platform-independent,  and choosing names with special characters could
+       someday make life difficult for users of a future port).  The  dot  (.)
+       character  is  relatively safe as long as there is at most one per root
+       name; some historical terminfo names use it.
+
+       The root name for a terminal or workstation console type should  almost
+       always  begin  with a vendor prefix (such as <STRONG>hp</STRONG> for Hewlett-Packard, <STRONG>wy</STRONG>
+       for Wyse, or <STRONG>att</STRONG> for AT&amp;T terminals), or a common name of the  terminal
+       line  (<STRONG>vt</STRONG>  for  the  VT  series  of  terminals from DEC, or <STRONG>sun</STRONG> for Sun
+       Microsystems workstation  consoles,  or  <STRONG>regent</STRONG>  for  the  ADDS  Regent
+       series.   You  can  list  the  terminfo  tree  to see what prefixes are
+       already in common use.  The root name prefix should  be  followed  when
+       appropriate by a model number; thus <STRONG>vt100</STRONG>, <STRONG>hp2621</STRONG>, <STRONG>wy50</STRONG>.
+
+       The  root  name for a PC-Unix console type should be the OS name, i.e.,
+       <STRONG>linux</STRONG>, <STRONG>bsdos</STRONG>, <STRONG>freebsd</STRONG>, <STRONG>netbsd</STRONG>.  It should <EM>not</EM> be <STRONG>console</STRONG> or  any  other
+       generic that might cause confusion in a multi-platform environment!  If
+       a model number follows, it should indicate either the OS release  level
+       or the console driver release level.
+
+       The  root name for a terminal emulator (assuming it does not fit one of
+       the standard ANSI or vt100 types) should  be  the  program  name  or  a
+       readily recognizable abbreviation of it (i.e., <STRONG>versaterm</STRONG>, <STRONG>ctrm</STRONG>).
+
+       Following  the  root name, you may add any reasonable number of hyphen-
+       separated feature suffixes.
+
+       2p   Has two pages of memory.  Likewise 4p, 8p, etc.
+
+       mc   Magic-cookie.  Some  terminals  (notably  older  Wyses)  can  only
+            support  one  attribute  without magic-cookie lossage.  Their base
+            entry is usually paired with another that has this suffix and uses
+            magic cookies to support multiple attributes.
+
+       -am  Enable auto-margin (right-margin wraparound).
+
+       -m   Mono mode - suppress color support.
+
+       -na  No  arrow  keys  -  termcap  ignores arrow keys which are actually
+            there on the terminal, so the user can use the arrow keys locally.
+
+       -nam No auto-margin - suppress am capability.
+
+       -nl  No labels - suppress soft labels.
+
+       -nsl No status line - suppress status line.
+
+       -pp  Has a printer port which is used.
+
+       -rv  Terminal in reverse video mode (black on white).
+
+       -s   Enable status line.
+
+       -vb  Use visible bell (flash) rather than beep.
+
+       -w   Wide; terminal is in 132-column mode.
+
+       Conventionally, if your terminal type is a variant intended to  specify
+       a  line  height,  that  suffix should go first.  So, for a hypothetical
+       FuBarCo model 2317 terminal in 30-line mode with  reverse  video,  best
+       form would be <STRONG>fubar-30-rv</STRONG> (rather than, say, "fubar-rv-30").
+
+       Terminal  types  that are written not as standalone entries, but rather
+       as components to be plugged into other entries  via  <STRONG>use</STRONG>  capabilities,
+       are distinguished by using embedded plus signs rather than dashes.
+
+       Commands which use a terminal type to control display often accept a -T
+       option that accepts a terminal name  argument.   Such  programs  should
+       fall  back  on  the  <STRONG>TERM</STRONG>  environment  variable  when  no -T option is
+       specified.

+       <STRONG><A HREF="curs_terminfo.3x.html">curs_terminfo(3x)</A></STRONG> manual page.
+
+       Depending  on  the  configuration,  these  may  be actual variables, or
+       macros (see <STRONG><A HREF="curs_threads.3x.html">curs_threads(3x)</A></STRONG>) which provide read-only access  to  <EM>curs-</EM>

+       After initializing the curses or terminfo interfaces, the <STRONG>acs_map</STRONG> array
+       holds  information  used to translate cells with the <STRONG>A_ALTCHARSET</STRONG> video
+       attribute into line-drawing characters.
+
+       The encoding of the information in this array has changed periodically.
+       Application  developers  need  only know that it is used for the "ACS_"
+       constants in &lt;curses.h&gt;.
+
+       The comparable data for the wide-character library is a  private  vari-
+       able.

+       After initializing the curses or terminfo interfaces, the <STRONG>cur_term</STRONG> con-
+       tains data describing the current terminal.  This variable is also  set
+       as a side-effect of <STRONG><A HREF="curs_initscr.3x.html">set_term(3x)</A></STRONG> and <STRONG><A HREF="curs_initscr.3x.html">delscreen(3x)</A></STRONG>.
+
+       It  is possible to save a value of <STRONG>cur_term</STRONG> for subsequent use as a pa-
+       rameter to <STRONG>set_term</STRONG>, for switching between screens.  Alternatively, one
+       can  save  the  return  value from <STRONG>newterm</STRONG> or <STRONG><A HREF="curs_terminfo.3x.html">setupterm(3x)</A></STRONG> to reuse in

+       The <STRONG><A HREF="tic.1m.html">tic(1)</A></STRONG> and <STRONG><A HREF="infocmp.1m.html">infocmp(1)</A></STRONG> programs use lookup tables for the  long  and

+       names for termcap capabilities.  These are available to other  applica-
+       tions,  although the hash-tables used by the terminfo and termcap func-
+       tions are not available.
+
+       The long terminfo capability names use a  "l"  (ell)  in  their  names:
+       <STRONG>boolfnames</STRONG>, <STRONG>numfnames</STRONG>, and <STRONG>strfnames</STRONG>.
+
+       These  are  the  short names for terminfo capabilities: <STRONG>boolnames</STRONG>, <STRONG>num-</STRONG>

+
+       These are the corresponding names used for termcap descriptions:  <STRONG>bool-</STRONG>

+       In addition to the variables, <STRONG>&lt;term.h&gt;</STRONG> also defines a symbol  for  each

+
+       The  actual definition of <STRONG>CUR</STRONG> depends upon the implementation, but each

+       header files.
+
+       All  implementations  which provide terminfo interfaces add definitions

+       <EM>Terminfo</EM>  is  a  database describing terminals, used by screen-oriented
+       programs  such  as  <STRONG>nvi(1)</STRONG>,  <STRONG>lynx(1)</STRONG>,   <STRONG>mutt(1)</STRONG>,   and   other   curses
+       applications,  using  high-level calls to libraries such as <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>.
+       It is also used via low-level calls by  non-curses  applications  which
+       may  be  screen-oriented  (such  as  <STRONG><A HREF="clear.1.html">clear(1)</A></STRONG>)  or  non-screen (such as
+       <STRONG><A HREF="tabs.1.html">tabs(1)</A></STRONG>).
+
+       <EM>Terminfo</EM> describes terminals by giving a set of capabilities which they
+       have, by specifying how to perform screen operations, and by specifying
+       padding requirements and initialization sequences.
+
+       This manual describes <STRONG>ncurses</STRONG> version 6.4 (patch 20221231).
+
+
+</PRE><H3><a name="h3-Terminfo-Entry-Syntax">Terminfo Entry Syntax</a></H3><PRE>
+       Entries in <EM>terminfo</EM> consist of a sequence of fields:
+
+       <STRONG>o</STRONG>   Each field ends with a comma "," (embedded commas  may  be  escaped
+           with a backslash or written as "\054").
+
+       <STRONG>o</STRONG>   White space between fields is ignored.
+
+       <STRONG>o</STRONG>   The first field in a <EM>terminfo</EM> entry begins in the first column.
+
+       <STRONG>o</STRONG>   Newlines  and  leading  whitespace (spaces or tabs) may be used for
+           formatting entries for readability.  These are removed from  parsed
+           entries.
+
+           The  <STRONG>infocmp</STRONG>  <STRONG>-f</STRONG> and <STRONG>-W</STRONG> options rely on this to format if-then-else
+           expressions, or  to  enforce  maximum  line-width.   The  resulting
+           formatted terminal description can be read by <STRONG>tic</STRONG>.
+
+       <STRONG>o</STRONG>   The  first  field for each terminal gives the names which are known
+           for the terminal, separated by "|" characters.
+
+           The first name given  is  the  most  common  abbreviation  for  the
+           terminal  (its  primary name), the last name given should be a long
+           name fully identifying the terminal  (see  <STRONG><A HREF="curs_termattrs.3x.html">longname(3x)</A></STRONG>),  and  all
+           others  are  treated as synonyms (aliases) for the primary terminal
+           name.
+
+           X/Open Curses advises that all names but  the  last  should  be  in
+           lower  case  and  contain no blanks; the last name may well contain
+           upper case and blanks for readability.
+
+           This implementation is not so strict; it allows mixed case  in  the
+           primary name and aliases.  If the last name has no embedded blanks,
+           it allows that to be both an alias and a  verbose  name  (but  will
+           warn about this ambiguity).
+
+       <STRONG>o</STRONG>   Lines  beginning  with  a  "#"  in  the first column are treated as
+           comments.
+
+           While comment lines are legal at any point, the output of <STRONG>captoinfo</STRONG>
+           and  <STRONG>infotocap</STRONG>  (aliases  for <STRONG>tic</STRONG>) will move comments so they occur
+           only between entries.
+
+       Terminal names (except for the last, verbose entry)  should  be  chosen
+       using  the  following  conventions.   The  particular piece of hardware
+       making up the terminal should have a root name,  thus  "hp2621".   This
+       name should not contain hyphens.  Modes that the hardware can be in, or
+       user preferences, should be indicated by appending a hyphen and a  mode
+       suffix.   Thus,  a  vt100  in  132-column  mode  would be vt100-w.  The
+       following suffixes should be used where possible:
+
+            <STRONG>Suffix</STRONG>                  <STRONG>Meaning</STRONG>                   <STRONG>Example</STRONG>
+            -<EM>nn</EM>      Number of lines on the screen            aaa-60
+            -<EM>n</EM>p      Number of pages of memory                c100-4p
+            -am      With automargins (usually the default)   vt100-am
+            -m       Mono mode; suppress color                ansi-m
+            -mc      Magic cookie; spaces when highlighting   wy30-mc
+            -na      No arrow keys (leave them in local)      c100-na
+            -nam     Without automatic margins                vt100-nam
+            -nl      No status line                           att4415-nl
+            -ns      No status line                           hp2626-ns
+            -rv      Reverse video                            c100-rv

+            -vb      Use visible bell instead of beep         wy370-vb
+            -w       Wide mode (&gt; 80 columns, usually 132)    vt100-w

+       The terminfo entry consists of  several  <EM>capabilities</EM>,  i.e.,  features
+       that  the  terminal  has,  or  methods  for  exercising  the terminal's
+       features.
+
+       After the first field (giving the name(s) of the terminal entry), there
+       should be one or more <EM>capability</EM> fields.  These are boolean, numeric or
+       string names with corresponding values:
+
+       <STRONG>o</STRONG>   Boolean capabilities are true  when  present,  false  when  absent.
+           There is no explicit value for boolean capabilities.
+
+       <STRONG>o</STRONG>   Numeric  capabilities  have  a  "#"  following  the  name,  then an
+           unsigned decimal integer value.
+
+       <STRONG>o</STRONG>   String capabilities have a "=" following the name, then  an  string
+           of characters making up the capability value.
+
+           String  capabilities  can be split into multiple lines, just as the
+           fields comprising a terminal  entry  can  be  split  into  multiple
+           lines.   While  blanks  between fields are ignored, blanks embedded
+           within a string value are retained, except for leading blanks on  a
+           line.
+
+       Any  capability  can  be  <EM>canceled</EM>,  i.e., suppressed from the terminal
+       entry, by following its name with "@" rather than a capability value.
+
+
+</PRE><H3><a name="h3-Similar-Terminals">Similar Terminals</a></H3><PRE>
+       If there are two very similar  terminals,  one  (the  variant)  can  be
+       defined   as  being  just  like  the  other  (the  base)  with  certain
+       exceptions.  In the definition of the variant,  the  string  capability
+       <STRONG>use</STRONG> can be given with the name of the base terminal:
+
+       <STRONG>o</STRONG>   The  capabilities  given before <STRONG>use</STRONG> override those in the base type
+           named by <STRONG>use</STRONG>.
+
+       <STRONG>o</STRONG>   If there are multiple <STRONG>use</STRONG> capabilities, they are merged in  reverse
+           order.   That  is,  the rightmost <STRONG>use</STRONG> reference is processed first,
+           then the one to its left, and so forth.
+
+       <STRONG>o</STRONG>   Capabilities given explicitly in the entry override  those  brought
+           in by <STRONG>use</STRONG> references.
+
+       A  capability  can  be  canceled  by placing <STRONG>xx@</STRONG> to the left of the use
+       reference that imports it, where <EM>xx</EM> is the  capability.   For  example,
+       the entry
+
+              2621-nl, smkx@, rmkx@, use=2621,
+
+       defines a 2621-nl that does not have the <STRONG>smkx</STRONG> or <STRONG>rmkx</STRONG> capabilities, and
+       hence does not turn on the function key labels  when  in  visual  mode.
+       This  is  useful  for  different modes for a terminal, or for different
+       user preferences.
+
+       An entry included via <STRONG>use</STRONG> can contain canceled capabilities, which have
+       the  same  effect as if those cancels were inline in the using terminal
+       entry.
+
+
+</PRE><H3><a name="h3-Predefined-Capabilities">Predefined Capabilities</a></H3><PRE>
+       The following is a complete table of the  capabilities  included  in  a
+       terminfo  description  block  and available to terminfo-using code.  In
+       each line of the table,
+
+       The <STRONG>variable</STRONG> is the name by  which  the  programmer  (at  the  terminfo
+       level) accesses the capability.
+
+       The  <STRONG>capname</STRONG> is the short name used in the text of the database, and is
+       used by a person updating the database.   Whenever  possible,  capnames
+       are chosen to be the same as or similar to the ANSI X3.64-1979 standard
+       (now superseded by  ECMA-48,  which  uses  identical  or  very  similar
+       names).    Semantics   are   also   intended  to  match  those  of  the
+       specification.
+
+       The termcap code is the old <STRONG>termcap</STRONG> capability name (some  capabilities
+       are new, and have names which termcap did not originate).
+
+       Capability  names have no hard length limit, but an informal limit of 5
+       characters has been adopted to keep them short and to allow the tabs in
+       the source file <STRONG>Caps</STRONG> to line up nicely.
+
+       Finally,  the description field attempts to convey the semantics of the
+       capability.  You may find some codes in the description field:
+
+       (P)    indicates that padding may be specified
+
+       #[1-9] in the description field indicates that  the  string  is  passed
+              through <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG> with parameters as given (#<EM>i</EM>).
+
+              If  no  parameters  are  listed  in the description, passing the
+              string through <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG> may give unexpected results,  e.g.,  if
+              it contains percent (%%) signs.
+
+       (P*)   indicates  that  padding may vary in proportion to the number of
+              lines affected
+
+       (#<EM>i</EM>)   indicates the <EM>i</EM>th parameter.
+
+
+       These are the boolean capabilities:
+
+
+                  <STRONG>Variable</STRONG>            <STRONG>Cap-</STRONG>      <STRONG>TCap</STRONG>       <STRONG>Description</STRONG>

+
+        The XSI Curses standard added these hardcopy capabilities.  They  were
+        used  in  some post-4.1 versions of System V curses, e.g., Solaris 2.5
+        and IRIX 6.x.  Except for <STRONG>YI</STRONG>, the <STRONG>ncurses</STRONG> termcap names for  them  are
+        invented.   According to the XSI Curses standard, they have no termcap
+        names.  If your compiled terminfo entries use these, they may  not  be
+        binary-compatible with System V terminfo entries after SVr4.1; beware!

+       The  preceding  section  listed the <EM>predefined</EM> capabilities.  They deal
+       with some special features for terminals no longer (or possibly  never)
+       produced.   Occasionally  there are special features of newer terminals
+       which are awkward or impossible to represent by reusing the  predefined
+       capabilities.
+
+       <STRONG>ncurses</STRONG>    addresses   this   limitation   by   allowing   user-defined
+       capabilities.  The <STRONG>tic</STRONG> and <STRONG>infocmp</STRONG> programs provide the <STRONG>-x</STRONG>  option  for
+       this purpose.  When <STRONG>-x</STRONG> is set, <STRONG>tic</STRONG> treats unknown capabilities as user-
+       defined.  That is, if <STRONG>tic</STRONG> encounters a capability name  which  it  does
+       not  recognize, it infers its type (boolean, number or string) from the
+       syntax and makes an extended table  entry  for  that  capability.   The
+       <STRONG><A HREF="curs_extend.3x.html">use_extended_names(3x)</A></STRONG>  function  makes  this information conditionally
+       available to applications.   The  ncurses  library  provides  the  data
+       leaving most of the behavior to applications:
+
+       <STRONG>o</STRONG>   User-defined  capability  strings  whose  name  begins with "k" are
+           treated as function keys.
+
+       <STRONG>o</STRONG>   The types (boolean,  number,  string)  determined  by  <STRONG>tic</STRONG>  can  be
+           inferred by successful calls on <STRONG>tigetflag</STRONG>, etc.
+
+       <STRONG>o</STRONG>   If the capability name happens to be two characters, the capability
+           is also available through the termcap interface.
+
+       While termcap is said to be  extensible  because  it  does  not  use  a
+       predefined  set of capabilities, in practice it has been limited to the
+       capabilities defined by terminfo implementations.   As  a  rule,  user-
+       defined capabilities intended for use by termcap applications should be
+       limited to booleans and numbers to avoid running  past  the  1023  byte
+       limit  assumed  by  termcap implementations and their applications.  In
+       particular, providing extended sets  of  function  keys  (past  the  60
+       numbered keys and the handful of special named keys) is best done using
+       the longer names available using terminfo.

+       Entries may continue onto multiple lines by placing white space at  the

+       lines beginning with "#".  Capabilities in <EM>terminfo</EM> are of three types:
+
+       <STRONG>o</STRONG>   Boolean capabilities which indicate  that  the  terminal  has  some
+           particular feature,
+
+       <STRONG>o</STRONG>   numeric capabilities giving the size of the terminal or the size of
+           particular delays, and
+
+       <STRONG>o</STRONG>   string capabilities, which give a sequence which  can  be  used  to
+           perform particular terminal operations.
+
+
+</PRE><H3><a name="h3-Types-of-Capabilities">Types of Capabilities</a></H3><PRE>
+       All capabilities have names.  For instance, the fact that ANSI-standard
+       terminals have <EM>automatic</EM> <EM>margins</EM> (i.e., an automatic return  and  line-
+       feed  when the end of a line is reached) is indicated by the capability
+       <STRONG>am</STRONG>.  Hence the description of ansi includes <STRONG>am</STRONG>.   Numeric  capabilities
+       are  followed  by  the  character  "#" and then a positive value.  Thus
+       <STRONG>cols</STRONG>, which indicates the number of columns the terminal has, gives the
+       value  "80" for ansi.  Values for numeric capabilities may be specified
+       in decimal, octal or hexadecimal,  using  the  C  programming  language
+       conventions (e.g., 255, 0377 and 0xff or 0xFF).
+
+       Finally,  string  valued capabilities, such as <STRONG>el</STRONG> (clear to end of line
+       sequence) are given by the two-character  code,  an  "=",  and  then  a
+       string ending at the next following ",".
+
+       A  number  of  escape  sequences  are  provided  in  the  string valued
+       capabilities for easy encoding of characters there:
+
+       <STRONG>o</STRONG>   Both <STRONG>\E</STRONG> and <STRONG>\e</STRONG> map to an ESCAPE character,
+
+       <STRONG>o</STRONG>   <STRONG>^x</STRONG> maps to a control-x for any appropriate <EM>x</EM>, and
+
+       <STRONG>o</STRONG>   the sequences
+
+             <STRONG>\n</STRONG>, <STRONG>\l</STRONG>, <STRONG>\r</STRONG>, <STRONG>\t</STRONG>, <STRONG>\b</STRONG>, <STRONG>\f</STRONG>, and <STRONG>\s</STRONG>
+
+           produce
+
+             <EM>newline</EM>, <EM>line-feed</EM>, <EM>return</EM>, <EM>tab</EM>, <EM>backspace</EM>, <EM>form-feed</EM>, and <EM>space</EM>,
+
+           respectively.
+
+       X/Open Curses does not say what "appropriate <EM>x</EM>" might be.  In practice,
+       that  is a printable ASCII graphic character.  The special case "^?" is
+       interpreted as DEL (127).  In all other cases, the character  value  is
+       AND'd  with 0x1f, mapping to ASCII control codes in the range 0 through
+       31.
+
+       Other escapes include
+
+       <STRONG>o</STRONG>   <STRONG>\^</STRONG> for <STRONG>^</STRONG>,
+
+       <STRONG>o</STRONG>   <STRONG>\\</STRONG> for <STRONG>\</STRONG>,
+
+       <STRONG>o</STRONG>   <STRONG>\</STRONG>, for comma,
+
+       <STRONG>o</STRONG>   <STRONG>\:</STRONG> for <STRONG>:</STRONG>,
+
+       <STRONG>o</STRONG>   and <STRONG>\0</STRONG> for null.
+
+           <STRONG>\0</STRONG> will produce \200, which does not terminate a string but behaves
+           as  a null character on most terminals, providing CS7 is specified.
+           See <STRONG>stty(1)</STRONG>.
+
+           The reason for this quirk is to maintain  binary  compatibility  of
+           the  compiled  terminfo files with other implementations, e.g., the
+           SVr4 systems, which document this.   Compiled  terminfo  files  use
+           null-terminated  strings,  with  no  lengths.  Modifying this would
+           require a new binary  format,  which  would  not  work  with  other
+           implementations.
+
+       Finally, characters may be given as three octal digits after a <STRONG>\</STRONG>.
+
+       A  delay  in  milliseconds  may appear anywhere in a string capability,
+       enclosed in $&lt;..&gt; brackets, as in <STRONG>el</STRONG>=\EK$&lt;5&gt;,  and  padding  characters
+       are supplied by <STRONG><A HREF="curs_terminfo.3x.html">tputs(3x)</A></STRONG> to provide this delay.
+
+       <STRONG>o</STRONG>   The  delay  must  be  a  number  with  at most one decimal place of
+           precision; it may be followed by suffixes "*" or "/" or both.
+
+       <STRONG>o</STRONG>   A "*" indicates that the padding required is  proportional  to  the
+           number  of lines affected by the operation, and the amount given is
+           the per-affected-unit padding required.  (In  the  case  of  insert
+           character, the factor is still the number of <EM>lines</EM> affected.)
+
+           Normally, padding is advisory if the device has the <STRONG>xon</STRONG> capability;
+           it is used for cost computation but does not trigger delays.
+
+       <STRONG>o</STRONG>   A "/" suffix indicates that the padding is mandatory and  forces  a
+           delay of the given number of milliseconds even on devices for which
+           <STRONG>xon</STRONG> is present to indicate flow control.
+
+       Sometimes individual capabilities must be commented out.  To  do  this,
+       put  a  period before the capability name.  For example, see the second
+       <STRONG>ind</STRONG> in the example above.
+
+
+</PRE><H3><a name="h3-Fetching-Compiled-Descriptions">Fetching Compiled Descriptions</a></H3><PRE>
+       The <STRONG>ncurses</STRONG> library  searches  for  terminal  descriptions  in  several
+       places.   It  uses only the first description found.  The library has a
+       compiled-in list of  places  to  search  which  can  be  overridden  by
+       environment  variables.   Before starting to search, <STRONG>ncurses</STRONG> eliminates
+       duplicates in its search list.
+
+       <STRONG>o</STRONG>   If the environment variable TERMINFO is set, it is  interpreted  as
+           the pathname of a directory containing the compiled description you
+           are working on.  Only that directory is searched.
+
+       <STRONG>o</STRONG>   If TERMINFO is not set, <STRONG>ncurses</STRONG> will instead look in the  directory
+           <STRONG>$HOME/.terminfo</STRONG> for a compiled description.
+
+       <STRONG>o</STRONG>   Next,  if  the  environment  variable TERMINFO_DIRS is set, <STRONG>ncurses</STRONG>
+           will interpret the contents of that variable as a  list  of  colon-
+           separated directories (or database files) to be searched.
+
+           An  empty directory name (i.e., if the variable begins or ends with
+           a colon, or contains adjacent colons) is interpreted as the  system
+           location <EM>/usr/share/terminfo</EM>.
+
+       <STRONG>o</STRONG>   Finally, <STRONG>ncurses</STRONG> searches these compiled-in locations:
+
+           <STRONG>o</STRONG>   a list of directories (no default value), and
+
+           <STRONG>o</STRONG>   the   system   terminfo   directory,  <EM>/usr/share/terminfo</EM>  (the
+               compiled-in default).
+
+
+</PRE><H3><a name="h3-Preparing-Descriptions">Preparing Descriptions</a></H3><PRE>
+       We now outline how to prepare  descriptions  of  terminals.   The  most
+       effective  way  to  prepare  a terminal description is by imitating the
+       description of a similar  terminal  in  <EM>terminfo</EM>  and  to  build  up  a
+       description gradually, using partial descriptions with <EM>vi</EM> or some other
+       screen-oriented program to check that they are correct.  Be aware  that
+       a  very  unusual terminal may expose deficiencies in the ability of the
+       <EM>terminfo</EM> file to describe it or bugs in the screen-handling code of the
+       test program.
+
+       To  get the padding for insert line right (if the terminal manufacturer
+       did not document it) a severe test is to edit  a  large  file  at  9600
+       baud, delete 16 or so lines from the middle of the screen, then hit the
+       "u" key several times quickly.  If the terminal messes up, more padding
+       is usually needed.  A similar test can be used for insert character.
+
+
+</PRE><H3><a name="h3-Basic-Capabilities">Basic Capabilities</a></H3><PRE>
+       The  number  of  columns  on each line for the terminal is given by the
+       <STRONG>cols</STRONG> numeric capability.  If the terminal is a CRT, then the number  of
+       lines  on the screen is given by the <STRONG>lines</STRONG> capability.  If the terminal
+       wraps around to the beginning of the next  line  when  it  reaches  the
+       right  margin,  then it should have the <STRONG>am</STRONG> capability.  If the terminal
+       can clear its screen, leaving the cursor in  the  home  position,  then
+       this  is  given  by  the  <STRONG>clear</STRONG>  string  capability.   If  the terminal
+       overstrikes (rather than clearing a position when a character is struck
+       over)  then  it  should  have  the <STRONG>os</STRONG> capability.  If the terminal is a
+       printing terminal, with no soft copy unit, give it both <STRONG>hc</STRONG> and <STRONG>os</STRONG>.  (<STRONG>os</STRONG>
+       applies  to  storage scope terminals, such as TEKTRONIX 4010 series, as
+       well as hard copy and APL terminals.)  If there is a code to  move  the
+       cursor to the left edge of the current row, give this as <STRONG>cr</STRONG>.  (Normally
+       this will be carriage return,  control/M.)   If  there  is  a  code  to
+       produce an audible signal (bell, beep, etc) give this as <STRONG>bel</STRONG>.
+
+       If there is a code to move the cursor one position to the left (such as
+       backspace) that capability should be given as <STRONG>cub1</STRONG>.   Similarly,  codes
+       to  move  to the right, up, and down should be given as <STRONG>cuf1</STRONG>, <STRONG>cuu1</STRONG>, and
+       <STRONG>cud1</STRONG>.  These local cursor motions should not alter the text  they  pass
+       over,  for  example,  you  would  not normally use "<STRONG>cuf1</STRONG>= " because the
+       space would erase the character moved over.
+
+       A very important point here is that the local cursor motions encoded in
+       <EM>terminfo</EM>  are  undefined  at  the left and top edges of a CRT terminal.
+       Programs should never attempt to backspace around the left edge, unless
+       <STRONG>bw</STRONG>  is given, and never attempt to go up locally off the top.  In order
+       to scroll text up, a program will go to the bottom left corner  of  the
+       screen and send the <STRONG>ind</STRONG> (index) string.
+
+       To  scroll  text  down,  a  program  goes to the top left corner of the
+       screen and sends the <STRONG>ri</STRONG> (reverse index) string.  The strings <STRONG>ind</STRONG> and <STRONG>ri</STRONG>
+       are undefined when not on their respective corners of the screen.
+
+       Parameterized  versions  of  the  scrolling  sequences are <STRONG>indn</STRONG> and <STRONG>rin</STRONG>
+       which have the same semantics as <STRONG>ind</STRONG> and <STRONG>ri</STRONG> except that they  take  one
+       parameter,  and scroll that many lines.  They are also undefined except
+       at the appropriate edge of the screen.
+
+       The <STRONG>am</STRONG> capability tells whether the cursor sticks at the right edge  of
+       the  screen when text is output, but this does not necessarily apply to
+       a <STRONG>cuf1</STRONG> from the last column.  The only local motion  which  is  defined
+       from  the  left  edge is if <STRONG>bw</STRONG> is given, then a <STRONG>cub1</STRONG> from the left edge
+       will move to the right edge of the previous row.  If <STRONG>bw</STRONG> is  not  given,
+       the  effect  is undefined.  This is useful for drawing a box around the
+       edge of the screen, for example.  If the terminal has switch selectable
+       automatic  margins,  the <EM>terminfo</EM> file usually assumes that this is on;
+       i.e., <STRONG>am</STRONG>.  If the terminal has a  command  which  moves  to  the  first
+       column  of  the  next line, that command can be given as <STRONG>nel</STRONG> (newline).
+       It does not matter if the command clears the remainder of  the  current
+       line,  so  if the terminal has no <STRONG>cr</STRONG> and <STRONG>lf</STRONG> it may still be possible to
+       craft a working <STRONG>nel</STRONG> out of one or both of them.
+
+       These  capabilities  suffice  to  describe  hard-copy  and  "glass-tty"
+       terminals.  Thus the model 33 teletype is described as
+
+       33|tty33|tty|model 33 teletype,
+               bel=^G, cols#72, cr=^M, cud1=^J, hc, ind=^J, os,
+
+       while the Lear Siegler ADM-3 is described as
+
+       adm3|3|lsi adm3,
+               am, bel=^G, clear=^Z, cols#80, cr=^M, cub1=^H, cud1=^J,

+       Cursor  addressing  and  other  strings  requiring  parameters  in  the
+       terminal are described  by  a  parameterized  string  capability,  with
+       <EM>printf</EM>-like  escapes  such  as  <EM>%x</EM>  in it.  For example, to address the
+       cursor, the <STRONG>cup</STRONG> capability is given, using two parameters: the row  and
+       column  to  address  to.   (Rows and columns are numbered from zero and
+       refer to the physical screen visible to the user,  not  to  any  unseen
+       memory.)   If  the terminal has memory relative cursor addressing, that
+       can be indicated by <STRONG>mrcup</STRONG>.
+
+       The parameter mechanism uses a stack and special <STRONG>%</STRONG> codes to  manipulate
+       it.   Typically  a  sequence  will  push one of the parameters onto the
+       stack and then print it in  some  format.   Print  (e.g.,  "%d")  is  a
+       special  case.  Other operations, including "%t" pop their operand from
+       the stack.   It  is  noted  that  more  complex  operations  are  often
+       necessary, e.g., in the <STRONG>sgr</STRONG> string.
+
+       The <STRONG>%</STRONG> encodings have the following meanings:
+
+       <STRONG>%%</STRONG>   outputs "%"
+
+       <STRONG>%</STRONG><EM>[[</EM>:<EM>]flags][width[.precision]][</EM><STRONG>doxXs</STRONG><EM>]</EM>
+            as  in  <STRONG>printf(3)</STRONG>,  flags are <EM>[-+#]</EM> and <EM>space</EM>.  Use a ":" to allow
+            the next character to be a "-" flag, avoiding interpreting "%-" as
+            an operator.

+

+            get static variable <EM>[a-z]</EM> and push it
+
+            The  terms  "static"  and "dynamic" are misleading.  Historically,
+            these are simply two different sets of variables, whose values are
+            not  reset  between calls to <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG>.  However, that fact is not
+            documented in other implementations.  Relying on it will adversely
+            impact portability to other implementations:
+
+            <STRONG>o</STRONG>   SVr2  curses  supported <EM>dynamic</EM> variables.  Those are set only
+                by a <STRONG>%P</STRONG> operator.  A <STRONG>%g</STRONG> for a  given  variable  without  first
+                setting  it  with  <STRONG>%P</STRONG> will give unpredictable results, because
+                dynamic variables are an  uninitialized  local  array  on  the
+                stack in the <STRONG>tparm</STRONG> function.
+
+            <STRONG>o</STRONG>   SVr3.2  curses supported <EM>static</EM> variables.  Those are an array
+                in the <STRONG>TERMINAL</STRONG> structure (declared in <STRONG>term.h</STRONG>), and are zeroed
+                automatically when the <STRONG>setupterm</STRONG> function allocates the data.
+
+            <STRONG>o</STRONG>   SVr4 curses made no further improvements to the <EM>dynamic/static</EM>
+                variable feature.
+
+            <STRONG>o</STRONG>   Solaris XPG4 curses does not distinguish between  <EM>dynamic</EM>  and
+                <EM>static</EM>  variables.  They are the same.  Like SVr4 curses, XPG4
+                curses does not initialize these explicitly.
+
+            <STRONG>o</STRONG>   Before version 6.3, ncurses stores  both  <EM>dynamic</EM>  and  <EM>static</EM>
+                variables in persistent storage, initialized to zeros.
+
+            <STRONG>o</STRONG>   Beginning  with version 6.3, ncurses stores <EM>static</EM> and <EM>dynamic</EM>
+                variables in the same manner as SVr4.
+
+                <STRONG>o</STRONG>   Unlike  other  implementations,  ncurses   zeros   dynamic
+                    variables before the first <STRONG>%g</STRONG> or <STRONG>%P</STRONG> operator.
+
+                <STRONG>o</STRONG>   Like  SVr2,  the  scope of dynamic variables in ncurses is
+                    within the current call to <STRONG>tparm</STRONG>.  Use static variables if
+                    persistent storage is needed.

+            (false), control passes to the <STRONG>%e</STRONG> (else) part.

+

+
+            Use the <STRONG>-f</STRONG> option of <STRONG>tic</STRONG> or <STRONG>infocmp</STRONG> to see the  structure  of  if-
+            then-else's.  Some strings, e.g., <STRONG>sgr</STRONG> can be very complicated when
+            written on one line.  The <STRONG>-f</STRONG> option splits the string  into  lines
+            with the parts indented.
+
+       Binary  operations  are  in postfix form with the operands in the usual
+       order.  That is, to get x-5 one  would  use  "%gx%{5}%-".   <STRONG>%P</STRONG>  and  <STRONG>%g</STRONG>
+       variables are persistent across escape-string evaluations.
+
+       Consider  the HP2645, which, to get to row 3 and column 12, needs to be
+       sent \E&amp;a12c03Y padded for 6 milliseconds.  Note that the order of  the
+       rows  and  columns  is  inverted  here, and that the row and column are
+       printed   as   two   digits.     Thus    its    <STRONG>cup</STRONG>    capability    is
+       "cup=6\E&amp;%p2%2dc%p1%2dY".
+
+       The  Microterm ACT-IV needs the current row and column sent preceded by
+       a  <STRONG>^T</STRONG>,  with  the  row   and   column   simply   encoded   in   binary,
+       "cup=^T%p1%c%p2%c".   Terminals  which  use  "%c"  need  to  be able to
+       backspace the cursor (<STRONG>cub1</STRONG>), and to move the cursor up one line on  the
+       screen  (<STRONG>cuu1</STRONG>).   This  is  necessary  because it is not always safe to
+       transmit <STRONG>\n</STRONG> <STRONG>^D</STRONG> and <STRONG>\r</STRONG>, as the system may change or discard them.   (The
+       library  routines  dealing with terminfo set tty modes so that tabs are
+       never expanded, so \t is safe to send.  This turns out to be  essential
+       for the Ann Arbor 4080.)
+
+       A  final example is the LSI ADM-3a, which uses row and column offset by
+       a blank character, thus "cup=\E=%p1%' '%+%c%p2%' '%+%c".  After sending
+       "\E=",  this  pushes  the first parameter, pushes the ASCII value for a
+       space (32), adds them (pushing the sum on the stack in place of the two
+       previous  values) and outputs that value as a character.  Then the same
+       is done for the second parameter.  More complex arithmetic is  possible
+       using the stack.

+       If  the  terminal has a fast way to home the cursor (to very upper left
+       corner of screen) then this can be given as <STRONG>home</STRONG>; similarly a fast  way
+       of  getting  to the lower left-hand corner can be given as <STRONG>ll</STRONG>; this may
+       involve going up with <STRONG>cuu1</STRONG> from the home position, but a program should
+       never do this itself (unless <STRONG>ll</STRONG> does) because it can make no assumption
+       about the effect of moving up from the home position.   Note  that  the
+       home  position  is  the  same  as  addressing to (0,0): to the top left
+       corner of the screen, not of memory.  (Thus, the  \EH  sequence  on  HP
+       terminals cannot be used for <STRONG>home</STRONG>.)
+
+       If the terminal has row or column absolute cursor addressing, these can
+       be given as single  parameter  capabilities  <STRONG>hpa</STRONG>  (horizontal  position
+       absolute)  and  <STRONG>vpa</STRONG>  (vertical position absolute).  Sometimes these are
+       shorter than the more general  two  parameter  sequence  (as  with  the
+       hp2645)   and  can  be  used  in  preference  to  <STRONG>cup</STRONG>.   If  there  are
+       parameterized local motions (e.g., move <EM>n</EM> spaces to  the  right)  these
+       can  be  given  as  <STRONG>cud</STRONG>,  <STRONG>cub</STRONG>,  <STRONG>cuf</STRONG>,  and  <STRONG>cuu</STRONG>  with a single parameter
+       indicating how many spaces to move.  These are primarily useful if  the
+       terminal does not have <STRONG>cup</STRONG>, such as the TEKTRONIX 4025.
+
+       If  the  terminal  needs to be in a special mode when running a program
+       that uses these capabilities, the codes to enter and exit this mode can
+       be  given as <STRONG>smcup</STRONG> and <STRONG>rmcup</STRONG>.  This arises, for example, from terminals
+       like the Concept with more than one page of memory.   If  the  terminal
+       has  only  memory  relative  cursor  addressing and not screen relative
+       cursor addressing, a one screen-sized window must  be  fixed  into  the
+       terminal for cursor addressing to work properly.  This is also used for
+       the TEKTRONIX 4025, where <STRONG>smcup</STRONG> sets the command character  to  be  the
+       one  used  by  terminfo.   If  the  <STRONG>smcup</STRONG> sequence will not restore the

+
+</PRE><H3><a name="h3-Margins">Margins</a></H3><PRE>
+       SVr4  (and  X/Open Curses) list several string capabilities for setting
+       margins.  Two were intended for use with  terminals,  and  another  six
+       were intended for use with printers.
+
+       <STRONG>o</STRONG>   The two terminal capabilities assume that the terminal may have the
+           capability of setting the left and/or right margin at  the  current
+           cursor column position.
+
+       <STRONG>o</STRONG>   The printer capabilities assume that the printer may have two types
+           of capability:
+
+           <STRONG>o</STRONG>   the ability to set a top and/or bottom margin using the current
+               line position, and
+
+           <STRONG>o</STRONG>   parameterized  capabilities  for setting the top, bottom, left,
+               right margins given the number of rows or columns.
+
+       In practice, the categorization into "terminal" and  "printer"  is  not
+       suitable:
+
+       <STRONG>o</STRONG>   The  AT&amp;T  SVr4  terminal  database  uses <STRONG>smgl</STRONG> four times, for AT&amp;T
+           hardware.
+
+           Three of the four are printers.   They  lack  the  ability  to  set
+           left/right margins by specifying the column.
+
+       <STRONG>o</STRONG>   Other  (non-AT&amp;T) terminals may support margins but using different
+           assumptions from AT&amp;T.
+
+           For instance, the DEC VT420 supports left/right margins,  but  only
+           using a column parameter.  As an added complication, the VT420 uses
+           two settings to fully enable left/right margins (left/right  margin
+           mode,  and  origin  mode).   The  former enables the margins, which
+           causes printed text to wrap  within  margins,  but  the  latter  is
+           needed to prevent cursor-addressing outside those margins.
+
+       <STRONG>o</STRONG>   Both  DEC  VT420  left/right  margins are set with a single control
+           sequence.  If either is omitted, the corresponding margin is set to
+           the  left  or  right  edge  of the display (rather than leaving the
+           margin unmodified).
+
+       These are the margin-related capabilities:
+
+                <STRONG>Name</STRONG>       <STRONG>Description</STRONG>
+                ------------------------------------------------------
+                smgl       Set left margin at current column

+                smgb       Set bottom margin at current line

+                smgtb      Set both top and bottom margins to <EM>T</EM> and <EM>B</EM>
+
+       When writing an application that uses these  string  capabilities,  the
+       pairs  should be first checked to see if each capability in the pair is
+       set or only one is set:
+
+       <STRONG>o</STRONG>   If both <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG>  are  set,  each  is  used  with  a  single
+           argument,  <EM>N</EM>,  that  gives  the column number of the left and right
+           margin, respectively.
+
+       <STRONG>o</STRONG>   If both <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG> are set, each is used to set  the  top  and
+           bottom margin, respectively:
+
+           <STRONG>o</STRONG>   <STRONG>smgtp</STRONG> is used with a single argument, <EM>N</EM>, the line number of the
+               top margin.
+
+           <STRONG>o</STRONG>   <STRONG>smgbp</STRONG> is used with two arguments, <EM>N</EM> and <EM>M</EM>, that give  the  line
+               number of the bottom margin, the first counting from the top of
+               the page  and  the  second  counting  from  the  bottom.   This
+               accommodates  the two styles of specifying the bottom margin in
+               different manufacturers' printers.
+
+           When designing a terminfo entry for a printer that has  a  settable
+           bottom  margin,  only  the first or second argument should be used,
+           depending on the printer.  When developing an application that uses
+           <STRONG>smgbp</STRONG> to set the bottom margin, both arguments must be given.
+
+       Conversely, when only one capability in the pair is set:
+
+       <STRONG>o</STRONG>   If  only  one  of  <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> is set, then it is used with two
+           arguments, the column number of the left and right margins, in that
+           order.
+
+       <STRONG>o</STRONG>   Likewise,  if  only  one of <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG> is set, then it is used
+           with two arguments that give the top and bottom  margins,  in  that
+           order, counting from the top of the page.
+
+           When designing a terminfo entry for a printer that requires setting
+           both left and right or top and bottom margins simultaneously,  only
+           one  capability  in  the  pairs  <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> or <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG>
+           should be defined, leaving the other unset.
+
+       Except for very old terminal descriptions, e.g.,  those  developed  for
+       SVr4,  the  scheme  just  described  should be considered obsolete.  An
+       improved set of capabilities was added late in the SVr4 releases (<STRONG>smglr</STRONG>
+       and  <STRONG>smgtb</STRONG>),  which  explicitly  use  two  parameters  for  setting the
+       left/right or top/bottom margins.
+
+       When setting margins, the line- and column-values are zero-based.
+
+       The <STRONG>mgc</STRONG> string capability should  be  defined.   Applications  such  as
+       <STRONG><A HREF="tabs.1.html">tabs(1)</A></STRONG> rely upon this to reset all margins.

+       the end of the display, then this should be given as <STRONG>ed</STRONG>.   <STRONG>Ed</STRONG>  is  only

+       If  the  terminal  can  open a new blank line before the line where the
+       cursor is, this should be given as <STRONG>il1</STRONG>; this  is  done  only  from  the
+       first  position  of  a  line.  The cursor must then appear on the newly
+       blank line.  If the terminal can delete the line which  the  cursor  is
+       on,  then this should be given as <STRONG>dl1</STRONG>; this is done only from the first
+       position on the line to be deleted.  Versions of <STRONG>il1</STRONG> and <STRONG>dl1</STRONG> which take
+       a single parameter and insert or delete that many lines can be given as
+       <STRONG>il</STRONG> and <STRONG>dl</STRONG>.
+
+       If the terminal has a settable scrolling region (like  the  vt100)  the
+       command  to  set  this  can be described with the <STRONG>csr</STRONG> capability, which
+       takes two parameters: the top and bottom lines of the scrolling region.
+       The cursor position is, alas, undefined after using this command.
+
+       It  is possible to get the effect of insert or delete line using <STRONG>csr</STRONG> on
+       a properly chosen region; the <STRONG>sc</STRONG>  and  <STRONG>rc</STRONG>  (save  and  restore  cursor)
+       commands may be useful for ensuring that your synthesized insert/delete
+       string does not move the cursor.  (Note that  the  <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>  library
+       does   this   synthesis   automatically,   so   you  need  not  compose
+       insert/delete strings for an entry with <STRONG>csr</STRONG>).
+
+       Yet another way to construct insert  and  delete  might  be  to  use  a
+       combination  of  index  with  the  memory-lock  feature  found  on some
+       terminals  (like  the  HP-700/90  series,  which   however   also   has
+       insert/delete).
+
+       Inserting  lines  at  the  top or bottom of the screen can also be done
+       using <STRONG>ri</STRONG> or <STRONG>ind</STRONG> on many terminals without a  true  insert/delete  line,
+       and is often faster even on terminals with those features.
+
+       The  boolean  <STRONG>non_dest_scroll_region</STRONG>  should  be  set if each scrolling
+       window is effectively a view port on a screen-sized  canvas.   To  test
+       for  this  capability,  create  a scrolling region in the middle of the
+       screen, write something to the bottom line, move the cursor to the  top
+       of  the region, and do <STRONG>ri</STRONG> followed by <STRONG>dl1</STRONG> or <STRONG>ind</STRONG>.  If the data scrolled
+       off the bottom of the region by the <STRONG>ri</STRONG> re-appears,  then  scrolling  is
+       non-destructive.   System  V  and XSI Curses expect that <STRONG>ind</STRONG>, <STRONG>ri</STRONG>, <STRONG>indn</STRONG>,
+       and  <STRONG>rin</STRONG>  will  simulate  destructive  scrolling;  their  documentation
+       cautions  you  not  to  define  <STRONG>csr</STRONG>  unless  this is true.  This <STRONG>curses</STRONG>
+       implementation is more  liberal  and  will  do  explicit  erases  after
+       scrolling if <STRONG>ndsrc</STRONG> is defined.
+
+       If  the  terminal has the ability to define a window as part of memory,
+       which all commands affect, it should  be  given  as  the  parameterized
+       string  <STRONG>wind</STRONG>.  The four parameters are the starting and ending lines in
+       memory and the starting and ending columns in memory, in that order.
+
+       If the terminal can retain display memory above, then the <STRONG>da</STRONG> capability
+       should  be  given;  if  display  memory  can be retained below, then <STRONG>db</STRONG>
+       should be given.  These indicate that deleting a line or scrolling  may
+       bring  non-blank lines up from below or that scrolling back with <STRONG>ri</STRONG> may
+       bring down non-blank lines.

+
+</PRE><H3><a name="h3-Insert_Delete-Character">Insert/Delete Character</a></H3><PRE>
+       There are two basic kinds of  intelligent  terminals  with  respect  to
+       insert/delete  character  which  can  be described using <EM>terminfo.</EM>  The
+       most  common  insert/delete  character  operations  affect   only   the
+       characters  on the current line and shift characters off the end of the
+       line rigidly.  Other terminals, such as the Concept 100 and the  Perkin
+       Elmer  Owl,  make a distinction between typed and untyped blanks on the
+       screen, shifting upon an insert or delete only to an untyped  blank  on
+       the  screen  which  is  either  eliminated,  or expanded to two untyped
+       blanks.
+
+       You can determine the kind of terminal you have by clearing the  screen
+       and  then  typing  text separated by cursor motions.  Type "abc    def"
+       using local cursor motions (not  spaces)  between  the  "abc"  and  the
+       "def".   Then position the cursor before the "abc" and put the terminal
+       in insert mode.  If typing characters causes the rest of  the  line  to
+       shift  rigidly  and  characters to fall off the end, then your terminal
+       does not distinguish between blanks  and  untyped  positions.   If  the
+       "abc"  shifts over to the "def" which then move together around the end
+       of the current line and onto the next  as  you  insert,  you  have  the
+       second  type  of  terminal,  and  should  give the capability <STRONG>in</STRONG>, which
+       stands for "insert null".
+
+       While these are two logically  separate  attributes  (one  line  versus
+       multi-line  insert  mode,  and  special treatment of untyped spaces) we
+       have seen no terminals whose insert mode cannot be described  with  the
+       single attribute.
+
+       Terminfo  can  describe  both  terminals which have an insert mode, and
+       terminals which send a simple sequence to open a blank position on  the
+       current line.  Give as <STRONG>smir</STRONG> the sequence to get into insert mode.  Give
+       as <STRONG>rmir</STRONG> the sequence to leave  insert  mode.   Now  give  as  <STRONG>ich1</STRONG>  any
+       sequence  needed  to  be  sent  just before sending the character to be
+       inserted.  Most terminals with a true insert mode will not  give  <STRONG>ich1</STRONG>;
+       terminals  which  send a sequence to open a screen position should give
+       it here.
+
+       If your terminal has both, insert mode is usually preferable  to  <STRONG>ich1</STRONG>.
+       Technically,  you  should  not  give  both unless the terminal actually
+       requires both to be used in combination.  Accordingly, some  non-curses
+       applications  get  confused if both are present; the symptom is doubled
+       characters in an update using insert.  This requirement  is  now  rare;
+       most  <STRONG>ich</STRONG>  sequences do not require previous smir, and most smir insert
+       modes do not require <STRONG>ich1</STRONG> before each character.   Therefore,  the  new
+       <STRONG>curses</STRONG>  actually  assumes this is the case and uses either <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> or
+       <STRONG>ich</STRONG>/<STRONG>ich1</STRONG> as appropriate (but not both).  If you have to write an  entry
+       to  be  used  under  new curses for a terminal old enough to need both,
+       include the <STRONG>rmir</STRONG>/<STRONG>smir</STRONG> sequences in <STRONG>ich1</STRONG>.
+
+       If post insert padding is needed, give this as a number of milliseconds
+       in  <STRONG>ip</STRONG> (a string option).  Any other sequence which may need to be sent
+       after an insert of a single character may also be given in <STRONG>ip</STRONG>.  If your
+       terminal  needs  both  to be placed into an "insert mode" and a special
+       code to precede each inserted character, then both <STRONG>smir</STRONG>/<STRONG>rmir</STRONG>  and  <STRONG>ich1</STRONG>
+       can  be  given,  and  both  will be used.  The <STRONG>ich</STRONG> capability, with one
+       parameter, <EM>n</EM>, will repeat the effects of <STRONG>ich1</STRONG> <EM>n</EM> times.
+
+       If padding is necessary between characters typed while  not  in  insert
+       mode, give this as a number of milliseconds padding in <STRONG>rmp</STRONG>.
+
+       It  is  occasionally  necessary  to move around while in insert mode to
+       delete characters on the same line (e.g., if there is a tab  after  the
+       insertion  position).   If  your terminal allows motion while in insert
+       mode you can give the capability <STRONG>mir</STRONG> to  speed  up  inserting  in  this
+       case.   Omitting  <STRONG>mir</STRONG>  will affect only speed.  Some terminals (notably
+       Datamedia's) must not have <STRONG>mir</STRONG> because of the  way  their  insert  mode
+       works.
+
+       Finally,  you  can  specify <STRONG>dch1</STRONG> to delete a single character, <STRONG>dch</STRONG> with
+       one parameter, <EM>n</EM>, to delete <EM>n</EM> <EM>characters,</EM> and  delete  mode  by  giving
+       <STRONG>smdc</STRONG>  and  <STRONG>rmdc</STRONG>  to  enter  and exit delete mode (any mode the terminal
+       needs to be placed in for <STRONG>dch1</STRONG> to work).
+
+       A command to erase <EM>n</EM> characters  (equivalent  to  outputting  <EM>n</EM>  blanks
+       without moving the cursor) can be given as <STRONG>ech</STRONG> with one parameter.
+
+
+</PRE><H3><a name="h3-Highlighting_-Underlining_-and-Visible-Bells">Highlighting, Underlining, and Visible Bells</a></H3><PRE>
+       If your terminal has one or more kinds of display attributes, these can
+       be represented in a number of different ways.  You  should  choose  one
+       display  form  as  <EM>standout</EM>  <EM>mode</EM>,  representing a good, high contrast,
+       easy-on-the-eyes, format for  highlighting  error  messages  and  other
+       attention  getters.   (If  you  have a choice, reverse video plus half-
+       bright is good, or reverse video alone.)  The sequences  to  enter  and
+       exit  standout  mode  are given as <STRONG>smso</STRONG> and <STRONG>rmso</STRONG>, respectively.  If the
+       code to change into or out of standout mode  leaves  one  or  even  two
+       blank  spaces  on  the screen, as the TVI 912 and Teleray 1061 do, then
+       <STRONG>xmc</STRONG> should be given to tell how many spaces are left.
+
+       Codes to begin underlining and end underlining can be given as <STRONG>smul</STRONG> and
+       <STRONG>rmul</STRONG> respectively.  If the terminal has a code to underline the current
+       character and move the cursor one space  to  the  right,  such  as  the
+       Microterm Mime, this can be given as <STRONG>uc</STRONG>.
+
+       Other  capabilities  to  enter various highlighting modes include <STRONG>blink</STRONG>
+       (blinking) <STRONG>bold</STRONG> (bold or extra bright) <STRONG>dim</STRONG> (dim or  half-bright)  <STRONG>invis</STRONG>
+       (blanking  or invisible text) <STRONG>prot</STRONG> (protected) <STRONG>rev</STRONG> (reverse video) <STRONG>sgr0</STRONG>
+       (turn off <EM>all</EM> attribute modes) <STRONG>smacs</STRONG>  (enter  alternate  character  set
+       mode) and <STRONG>rmacs</STRONG> (exit alternate character set mode).  Turning on any of
+       these modes singly may or may not turn off other modes.
+
+       If there is a sequence to set arbitrary  combinations  of  modes,  this
+       should  be  given  as  <STRONG>sgr</STRONG> (set attributes), taking 9 parameters.  Each
+       parameter is either 0 or nonzero, as the corresponding attribute is  on
+       or  off.  The 9 parameters are, in order: standout, underline, reverse,
+       blink, dim, bold, blank, protect, alternate  character  set.   Not  all
+       modes  need  be  supported  by  <STRONG>sgr</STRONG>, only those for which corresponding
+       separate attribute commands exist.
+
+       For example, the DEC vt220 supports most of the modes:
+
+               <STRONG>tparm</STRONG> <STRONG>parameter</STRONG>      <STRONG>attribute</STRONG>        <STRONG>escape</STRONG> <STRONG>sequence</STRONG>
+
+               none                 none             \E[0m
+               p1                   standout         \E[0;1;7m
+               p2                   underline        \E[0;4m
+               p3                   reverse          \E[0;7m
+               p4                   blink            \E[0;5m
+               p5                   dim              not available
+               p6                   bold             \E[0;1m
+               p7                   invis            \E[0;8m
+               p8                   protect          not used
+               p9                   altcharset       ^O (off) ^N (on)
+
+       We begin each escape sequence by turning off any existing modes,  since
+       there  is  no quick way to determine whether they are active.  Standout
+       is set up to be  the  combination  of  reverse  and  bold.   The  vt220
+       terminal  has  a  protect  mode,  though it is not commonly used in sgr
+       because it protects characters on the screen from the host's  erasures.
+       The  altcharset  mode  also is different in that it is either ^O or ^N,
+       depending on whether it is off or on.  If all modes are turned on,  the
+       resulting sequence is \E[0;1;4;5;7;8m^N.
+
+       Some  sequences  are  common  to  different  modes.  For example, ;7 is
+       output when either p1 or p3 is true, that is,  if  either  standout  or
+       reverse modes are turned on.
+
+       Writing out the above sequences, along with their dependencies yields
+
+            <STRONG>sequence</STRONG>             <STRONG>when</STRONG> <STRONG>to</STRONG> <STRONG>output</STRONG>      <STRONG>terminfo</STRONG> <STRONG>translation</STRONG>
+
+            \E[0                 always              \E[0
+            ;1                   if p1 or p6         %?%p1%p6%|%t;1%;
+            ;4                   if p2               %?%p2%|%t;4%;
+            ;5                   if p4               %?%p4%|%t;5%;
+            ;7                   if p1 or p3         %?%p1%p3%|%t;7%;
+            ;8                   if p7               %?%p7%|%t;8%;
+            m                    always              m
+            ^N or ^O             if p9 ^N, else ^O   %?%p9%t^N%e^O%;
+
+       Putting this all together into the sgr sequence gives:
+
+           sgr=\E[0%?%p1%p6%|%t;1%;%?%p2%t;4%;%?%p4%t;5%;
+               %?%p1%p3%|%t;7%;%?%p7%t;8%;m%?%p9%t\016%e\017%;,
+
+       Remember  that  if  you specify sgr, you must also specify sgr0.  Also,
+       some implementations rely on sgr  being  given  if  sgr0  is,  Not  all
+       terminfo  entries  necessarily  have  an  sgr  string,  however.   Many
+       terminfo entries are derived from termcap entries  which  have  no  sgr
+       string.  The only drawback to adding an sgr string is that termcap also
+       assumes that sgr0 does not exit alternate character set mode.
+
+       Terminals  with  the  "magic  cookie"  glitch  (<STRONG>xmc</STRONG>)  deposit   special
+       "cookies"  when  they  receive mode-setting sequences, which affect the
+       display algorithm rather than having extra  bits  for  each  character.
+       Some  terminals, such as the HP 2621, automatically leave standout mode
+       when they move to a new line or  the  cursor  is  addressed.   Programs
+       using  standout mode should exit standout mode before moving the cursor
+       or sending a newline, unless the <STRONG>msgr</STRONG> capability, asserting that it  is
+       safe to move in standout mode, is present.
+
+       If  the  terminal has a way of flashing the screen to indicate an error
+       quietly (a bell replacement) then this can be given as <STRONG>flash</STRONG>;  it  must
+       not move the cursor.
+
+       If  the cursor needs to be made more visible than normal when it is not
+       on the bottom line (to make, for example, a non-blinking underline into
+       an  easier  to  find block or blinking underline) give this sequence as
+       <STRONG>cvvis</STRONG>.  If there is a way to make the cursor completely invisible, give
+       that  as  <STRONG>civis</STRONG>.  The capability <STRONG>cnorm</STRONG> should be given which undoes the
+       effects of both of these modes.
+
+       If your terminal correctly generates  underlined  characters  (with  no
+       special  codes  needed)  even  though  it does not overstrike, then you
+       should give the capability <STRONG>ul</STRONG>.  If  a  character  overstriking  another
+       leaves  both  characters  on the screen, specify the capability <STRONG>os</STRONG>.  If
+       overstrikes are erasable with a blank, then this should be indicated by

+       A  string to program screen labels should be specified as <STRONG>pln</STRONG>.  Each of
+       these strings takes two parameters: the function key number to  program
+       (from 0 to 10) and the string to program it with.  Function key numbers
+       out of this range may program undefined keys in  a  terminal  dependent
+       manner.   The  difference between the capabilities is that <STRONG>pfkey</STRONG> causes
+       pressing the given key to be the same as  the  user  typing  the  given
+       string;  <STRONG>pfloc</STRONG>  causes  the  string  to  be executed by the terminal in
+       local; and <STRONG>pfx</STRONG> causes the string to be transmitted to the computer.
+
+       The capabilities <STRONG>nlab</STRONG>, <STRONG>lw</STRONG> and <STRONG>lh</STRONG>  define  the  number  of  programmable
+       screen  labels  and  their  width and height.  If there are commands to
+       turn the labels on and off, give  them  in  <STRONG>smln</STRONG>  and  <STRONG>rmln</STRONG>.   <STRONG>smln</STRONG>  is
+       normally  output  after one or more pln sequences to make sure that the
+       change becomes visible.

+
+</PRE><H3><a name="h3-Tabs-and-Initialization">Tabs and Initialization</a></H3><PRE>
+       A few capabilities are used only for tabs:
+
+       <STRONG>o</STRONG>   If the terminal has hardware tabs, the command to  advance  to  the
+           next tab stop can be given as <STRONG>ht</STRONG> (usually control/I).
+
+       <STRONG>o</STRONG>   A "back-tab" command which moves leftward to the preceding tab stop
+           can be given as <STRONG>cbt</STRONG>.
+
+           By convention, if the teletype modes indicate that tabs  are  being
+           expanded  by  the  computer rather than being sent to the terminal,
+           programs should not use <STRONG>ht</STRONG> or <STRONG>cbt</STRONG> even if they are  present,  since
+           the user may not have the tab stops properly set.
+
+       <STRONG>o</STRONG>   If  the  terminal has hardware tabs which are initially set every <EM>n</EM>
+           spaces when the terminal is powered up, the numeric parameter <STRONG>it</STRONG> is
+           given, showing the number of spaces the tabs are set to.
+
+           The <STRONG>it</STRONG> capability is normally used by the <STRONG>tset</STRONG> command to determine
+           whether to set the mode for hardware tab expansion, and whether  to
+           set the tab stops.  If the terminal has tab stops that can be saved
+           in non-volatile memory, the terminfo description  can  assume  that
+           they are properly set.
+
+       Other capabilities include
+
+       <STRONG>o</STRONG>   <STRONG>is1</STRONG>, <STRONG>is2</STRONG>, and <STRONG>is3</STRONG>, initialization strings for the terminal,
+
+       <STRONG>o</STRONG>   <STRONG>iprog</STRONG>,  the  path  name  of  a  program to be run to initialize the
+           terminal,
+
+       <STRONG>o</STRONG>   and <STRONG>if</STRONG>, the name of a file containing long initialization strings.
+
+       These strings are expected to set the terminal  into  modes  consistent
+       with  the  rest of the terminfo description.  They are normally sent to
+       the terminal, by the <EM>init</EM> option of the <STRONG>tput</STRONG>  program,  each  time  the
+       user logs in.  They will be printed in the following order:
+
+              run the program
+                     <STRONG>iprog</STRONG>
+
+              output
+                     <STRONG>is1</STRONG> and
+                     <STRONG>is2</STRONG>
+
+              set the margins using
+                     <STRONG>mgc</STRONG> or
+                     <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> or
+                     <STRONG>smgl</STRONG> and <STRONG>smgr</STRONG>
+
+              set tabs using
+                     <STRONG>tbc</STRONG> and <STRONG>hts</STRONG>
+
+              print the file
+                     <STRONG>if</STRONG>
+
+              and finally output
+                     <STRONG>is3</STRONG>.
+
+       Most  initialization  is  done with <STRONG>is2</STRONG>.  Special terminal modes can be
+       set up without duplicating strings by putting the common  sequences  in
+       <STRONG>is2</STRONG> and special cases in <STRONG>is1</STRONG> and <STRONG>is3</STRONG>.
+
+       A  set  of  sequences  that  does a harder reset from a totally unknown
+       state can be given as <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rf</STRONG> and <STRONG>rs3</STRONG>, analogous to <STRONG>is1</STRONG> <STRONG>,</STRONG> <STRONG>is2</STRONG> <STRONG>,</STRONG> <STRONG>if</STRONG>
+       and  <STRONG>is3</STRONG>  respectively.   These  strings  are output by <EM>reset</EM> option of
+       <STRONG>tput</STRONG>, or by the <STRONG>reset</STRONG> program (an alias of <STRONG>tset</STRONG>), which  is  used  when
+       the terminal gets into a wedged state.  Commands are normally placed in
+       <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG> <STRONG>rs3</STRONG> and <STRONG>rf</STRONG> only if they produce annoying effects on the screen
+       and are not necessary when logging in.  For example, the command to set
+       the vt100 into 80-column mode would normally be part  of  <STRONG>is2</STRONG>,  but  it
+       causes  an  annoying  glitch  of  the screen and is not normally needed
+       since the terminal is usually already in 80-column mode.
+
+       The <STRONG>reset</STRONG> program writes strings including <STRONG>iprog</STRONG>,  etc.,  in  the  same
+       order  as  the  <EM>init</EM> program, using <STRONG>rs1</STRONG>, etc., instead of <STRONG>is1</STRONG>, etc.  If
+       any of <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>, or <STRONG>rf</STRONG> reset capability strings are  missing,  the
+       <STRONG>reset</STRONG>   program   falls  back  upon  the  corresponding  initialization
+       capability string.
+
+       If there are commands to set and clear tab stops, they can be given  as
+       <STRONG>tbc</STRONG> (clear all tab stops) and <STRONG>hts</STRONG> (set a tab stop in the current column
+       of every row).  If a more complex sequence is needed to  set  the  tabs
+       than can be described by this, the sequence can be placed in <STRONG>is2</STRONG> or <STRONG>if</STRONG>.
+
+       The  <STRONG>tput</STRONG>  <STRONG>reset</STRONG>  command uses the same capability strings as the <STRONG>reset</STRONG>
+       command, although the two programs (<STRONG>tput</STRONG> and <STRONG>reset</STRONG>)  provide  different
+       command-line options.
+
+       In  practice,  these  terminfo  capabilities  are  not  often  used  in
+       initialization of tabs (though they are required for the <STRONG>tabs</STRONG> program):
+
+       <STRONG>o</STRONG>   Almost all hardware terminals (at least those which supported tabs)
+           initialized those to every <EM>eight</EM> columns:
+
+           The  only  exception  was  the  AT&amp;T 2300 series, which set tabs to
+           every <EM>five</EM> columns.
+
+       <STRONG>o</STRONG>   In particular, developers  of  the  hardware  terminals  which  are
+           commonly  used  as  models  for  modern terminal emulators provided
+           documentation demonstrating that <EM>eight</EM> columns were the standard.
+
+       <STRONG>o</STRONG>   Because of this, the terminal initialization programs <STRONG>tput</STRONG> and <STRONG>tset</STRONG>
+           use   the  <STRONG>tbc</STRONG>  (<STRONG>clear_all_tabs</STRONG>)  and  <STRONG>hts</STRONG>  (<STRONG>set_tab</STRONG>)  capabilities
+           directly only when the <STRONG>it</STRONG> (<STRONG>init_tabs</STRONG>) capability is set to a  value
+           other than <EM>eight</EM>.
+
+
+</PRE><H3><a name="h3-Delays-and-Padding">Delays and Padding</a></H3><PRE>
+       Many  older  and slower terminals do not support either XON/XOFF or DTR
+       handshaking, including hard copy terminals and some very  archaic  CRTs
+       (including,  for  example,  DEC  VT100s).   These  may  require padding
+       characters after certain cursor motions and screen changes.
+
+       If the terminal uses xon/xoff handshaking for flow control (that is, it
+       automatically  emits  ^S  back  to  the host when its input buffers are
+       close to full), set <STRONG>xon</STRONG>.  This capability suppresses  the  emission  of
+       padding.   You  can  also  set  it  for  memory-mapped  console devices
+       effectively that do not have a speed limit.  Padding information should
+       still  be  included  so  that  routines can make better decisions about
+       relative costs, but actual pad characters will not be transmitted.
+
+       If <STRONG>pb</STRONG> (padding baud rate) is given, padding is suppressed at baud rates
+       below  the  value  of  <STRONG>pb</STRONG>.  If the entry has no padding baud rate, then
+       whether padding is emitted or not is completely controlled by <STRONG>xon</STRONG>.
+
+       If the terminal requires other than a null (zero) character as  a  pad,
+       then  this  can  be  given as <STRONG>pad</STRONG>.  Only the first character of the <STRONG>pad</STRONG>
+       string is used.
+
+
+</PRE><H3><a name="h3-Status-Lines">Status Lines</a></H3><PRE>
+       Some terminals have an extra "status line" which is not  normally  used
+       by software (and thus not counted in the terminal's <STRONG>lines</STRONG> capability).
+
+       The  simplest case is a status line which is cursor-addressable but not
+       part of the main scrolling region on the screen; the Heathkit H19 has a
+       status  line  of  this  kind,  as  would a 24-line VT100 with a 23-line
+       scrolling region set up on initialization.  This situation is indicated
+       by the <STRONG>hs</STRONG> capability.
+
+       Some  terminals  with status lines need special sequences to access the
+       status line.  These may be expressed as a string with single  parameter
+       <STRONG>tsl</STRONG>  which takes the cursor to a given zero-origin column on the status
+       line.  The  capability  <STRONG>fsl</STRONG>  must  return  to  the  main-screen  cursor
+       positions before the last <STRONG>tsl</STRONG>.  You may need to embed the string values
+       of <STRONG>sc</STRONG> (save  cursor)  and  <STRONG>rc</STRONG>  (restore  cursor)  in  <STRONG>tsl</STRONG>  and  <STRONG>fsl</STRONG>  to
+       accomplish this.
+
+       The  status  line is normally assumed to be the same width as the width
+       of the terminal.  If this is  untrue,  you  can  specify  it  with  the
+       numeric capability <STRONG>wsl</STRONG>.
+
+       A command to erase or blank the status line may be specified as <STRONG>dsl</STRONG>.
+
+       The  boolean  capability  <STRONG>eslok</STRONG>  specifies that escape sequences, tabs,
+       etc., work ordinarily in the status line.
+
+       The <STRONG>ncurses</STRONG> implementation does not yet use any of these  capabilities.
+       They are documented here in case they ever become important.

+
+       A few notes apply to the table itself:
+
+       <STRONG>o</STRONG>   X/Open  Curses  incorrectly  states that the mapping for <EM>lantern</EM> is
+           uppercase "I" although Unix implementations use the  lowercase  "i"
+           mapping.
+
+       <STRONG>o</STRONG>   The  DEC  VT100  implemented graphics using the alternate character
+           set feature, temporarily switching <EM>modes</EM> and sending characters  in
+           the  range  0x60  (96)  to 0x7e (126) (the <STRONG>acsc</STRONG> <STRONG>Value</STRONG> column in the
+           table).
+
+       <STRONG>o</STRONG>   The AT&amp;T terminal added graphics characters outside that range.
+
+           Some of the characters within the range do  not  match  the  VT100;
+           presumably  they  were  used in the AT&amp;T terminal: <EM>board</EM> <EM>of</EM> <EM>squares</EM>
+           replaces the VT100 <EM>newline</EM> symbol, while  <EM>lantern</EM>  <EM>symbol</EM>  replaces
+           the VT100 <EM>vertical</EM> <EM>tab</EM> symbol.  The other VT100 symbols for control
+           characters (<EM>horizontal</EM> <EM>tab</EM>, <EM>carriage</EM> <EM>return</EM> and <EM>line-feed</EM>) are  not
+           (re)used in curses.
+
+       The  best  way to define a new device's graphics set is to add a column
+       to a copy of this table for your terminal, giving the  character  which
+       (when  emitted  between  <STRONG>smacs</STRONG>/<STRONG>rmacs</STRONG>  switches) will be rendered as the
+       corresponding graphic.  Then read off the VT100/your terminal character
+       pairs right to left in sequence; these become the ACSC string.

+       The  curses  library  functions <STRONG>init_pair</STRONG> and <STRONG>init_color</STRONG> manipulate the
+       <EM>color</EM>  <EM>pairs</EM>  and  <EM>color</EM>  <EM>values</EM>  discussed  in   this   section   (see
+       <STRONG><A HREF="curs_color.3x.html">curs_color(3x)</A></STRONG> for details on these and related functions).
+
+       Most color terminals are either "Tektronix-like" or "HP-like":
+
+       <STRONG>o</STRONG>   Tektronix-like terminals have a predefined set of <EM>N</EM> colors (where <EM>N</EM>
+           is usually 8), and can set character-cell foreground and background
+           characters independently, mixing them into <EM>N</EM> * <EM>N</EM> color-pairs.
+
+       <STRONG>o</STRONG>   On  HP-like  terminals,  the  user  must  set  each  color  pair up
+           separately  (foreground  and  background  are   not   independently
+           settable).   Up  to  <EM>M</EM> color-pairs may be set up from 2*<EM>M</EM> different
+           colors.  ANSI-compatible terminals are Tektronix-like.
+
+       Some basic color capabilities are independent of the color method.  The
+       numeric  capabilities  <STRONG>colors</STRONG>  and <STRONG>pairs</STRONG> specify the maximum numbers of
+       colors and color-pairs that can be displayed  simultaneously.   The  <STRONG>op</STRONG>
+       (original pair) string resets foreground and background colors to their
+       default values for the terminal.  The <STRONG>oc</STRONG> string resets  all  colors  or
+       color-pairs  to  their default values for the terminal.  Some terminals
+       (including many PC terminal emulators)  erase  screen  areas  with  the
+       current  background  color rather than the power-up default background;
+       these should have the boolean capability <STRONG>bce</STRONG>.
+
+       While the  curses  library  works  with  <EM>color</EM>  <EM>pairs</EM>  (reflecting  the
+       inability  of  some  devices  to  set  foreground and background colors
+       independently), there  are  separate  capabilities  for  setting  these
+       features:
+
+       <STRONG>o</STRONG>   To   change  the  current  foreground  or  background  color  on  a
+           Tektronix-type terminal, use <STRONG>setaf</STRONG> (set ANSI foreground) and  <STRONG>setab</STRONG>
+           (set  ANSI  background)  or  <STRONG>setf</STRONG>  (set  foreground)  and <STRONG>setb</STRONG> (set
+           background).  These take one parameter, the color number.  The SVr4
+           documentation  describes only <STRONG>setaf</STRONG>/<STRONG>setab</STRONG>; the XPG4 draft says that
+           "If the terminal supports ANSI escape sequences to  set  background
+           and   foreground,   they  should  be  coded  as  <STRONG>setaf</STRONG>  and  <STRONG>setab</STRONG>,

+       It  is  important  to  not  confuse the two sets of color capabilities;
+       otherwise red/blue will be interchanged on the display.
+
+       On an HP-like terminal, use <STRONG>scp</STRONG> with a color-pair number  parameter  to
+       set which color pair is current.
+
+       Some terminals allow the <EM>color</EM> <EM>values</EM> to be modified:
+
+       <STRONG>o</STRONG>   On  a Tektronix-like terminal, the capability <STRONG>ccc</STRONG> may be present to
+           indicate that colors can be modified.  If so, the <STRONG>initc</STRONG>  capability
+           will take a color number (0 to <STRONG>colors</STRONG> - 1)and three more parameters
+           which describe the color.  These three parameters default to  being
+           interpreted  as  RGB  (Red,  Green,  Blue)  values.  If the boolean
+           capability <STRONG>hls</STRONG> is present, they are instead as HLS (Hue, Lightness,
+           Saturation) indices.  The ranges are terminal-dependent.
+
+       <STRONG>o</STRONG>   On  an HP-like terminal, <STRONG>initp</STRONG> may give a capability for changing a
+           color-pair value.  It will  take  seven  parameters;  a  color-pair
+           number  (0  to  <STRONG>max_pairs</STRONG>  -  1),  and two triples describing first
+           background and then foreground colors.  These  parameters  must  be
+           (Red,  Green,  Blue)  or  (Hue, Lightness, Saturation) depending on
+           <STRONG>hls</STRONG>.
+
+       On some color terminals,  colors  collide  with  highlights.   You  can
+       register  these collisions with the <STRONG>ncv</STRONG> capability.  This is a bit-mask
+       of  attributes  not  to  be  used  when  colors   are   enabled.    The
+       correspondence with the attributes understood by <STRONG>curses</STRONG> is as follows:

+       If the terminal requires other than a null (zero) character as  a  pad,
+       then  this  can  be  given as pad.  Only the first character of the pad
+       string is used.  If the terminal does not have a pad character, specify
+       npc.   Note that ncurses implements the termcap-compatible <STRONG>PC</STRONG> variable;
+       though the application may set this value to  something  other  than  a
+       null,  ncurses will test <STRONG>npc</STRONG> first and use napms if the terminal has no
+       pad character.
+
+       If the terminal can move up or down half a line, this can be  indicated
+       with  <STRONG>hu</STRONG>  (half-line  up)  and  <STRONG>hd</STRONG> (half-line down).  This is primarily
+       useful for superscripts and subscripts on hard-copy  terminals.   If  a
+       hard-copy terminal can eject to the next page (form feed), give this as
+       <STRONG>ff</STRONG> (usually control/L).
+
+       If there is a command to repeat a given character  a  given  number  of
+       times   (to   save  time  transmitting  a  large  number  of  identical
+       characters) this can be indicated with the  parameterized  string  <STRONG>rep</STRONG>.
+       The  first  parameter is the character to be repeated and the second is
+       the number of times to repeat it.  Thus, tparm(repeat_char, 'x', 10) is
+       the same as "xxxxxxxxxx".
+
+       If the terminal has a settable command character, such as the TEKTRONIX
+       4025, this can be indicated with <STRONG>cmdch</STRONG>.  A prototype command  character
+       is  chosen  which is used in all capabilities.  This character is given
+       in the <STRONG>cmdch</STRONG> capability to identify it.  The  following  convention  is
+       supported on some UNIX systems: The environment is to be searched for a
+       <STRONG>CC</STRONG> variable, and if found, all occurrences of the  prototype  character
+       are replaced with the character in the environment variable.
+
+       Terminal  descriptions  that  do not represent a specific kind of known
+       terminal, such as <EM>switch</EM>, <EM>dialup</EM>, <EM>patch</EM>, and  <EM>network</EM>,  should  include
+       the  <STRONG>gn</STRONG> (generic) capability so that programs can complain that they do
+       not know how to talk to the terminal.  (This capability does not  apply
+       to  <EM>virtual</EM>  terminal  descriptions  for which the escape sequences are
+       known.)
+
+       If the terminal has a "meta key" which acts as a shift key, setting the
+       8th  bit  of any character transmitted, this fact can be indicated with
+       <STRONG>km</STRONG>.  Otherwise, software will assume that the 8th bit is parity and  it
+       will  usually be cleared.  If strings exist to turn this "meta mode" on
+       and off, they can be given as <STRONG>smm</STRONG> and <STRONG>rmm</STRONG>.
+
+       If the terminal has more lines of memory than will fit on the screen at
+       once,  the number of lines of memory can be indicated with <STRONG>lm</STRONG>.  A value
+       of <STRONG>lm</STRONG>#0 indicates that the number of lines is not fixed, but that there
+       is still more memory than fits on the screen.
+
+       If  the terminal is one of those supported by the UNIX virtual terminal
+       protocol, the terminal number can be given as <STRONG>vt</STRONG>.
+
+       Media copy strings which control an auxiliary printer connected to  the
+       terminal  can  be  given as <STRONG>mc0</STRONG>: print the contents of the screen, <STRONG>mc4</STRONG>:
+       turn off the printer, and <STRONG>mc5</STRONG>: turn on the printer.  When  the  printer
+       is  on,  all text sent to the terminal will be sent to the printer.  It
+       is undefined whether the text is also displayed on the terminal  screen
+       when  the  printer  is  on.   A variation <STRONG>mc5p</STRONG> takes one parameter, and
+       leaves the printer on for as  many  characters  as  the  value  of  the
+       parameter, then turns the printer off.  The parameter should not exceed
+       255.  All text, including <STRONG>mc4</STRONG>, is transparently passed to  the  printer
+       while an <STRONG>mc5p</STRONG> is in effect.

+       Hazeltine  terminals, which do not allow "~" characters to be displayed

+
+       Terminals which ignore a line-feed immediately after an <STRONG>am</STRONG>  wrap,  such
+       as the Concept and vt100, should indicate <STRONG>xenl</STRONG>.
+
+       If  <STRONG>el</STRONG>  is  required  to get rid of standout (instead of merely writing
+       normal text on top of it), <STRONG>xhp</STRONG> should be given.
+
+       Teleray terminals, where tabs turn all characters moved over to blanks,
+       should  indicate  <STRONG>xt</STRONG> (destructive tabs).  Note: the variable indicating
+       this  is  now  "dest_tabs_magic_smso";  in  older  versions,   it   was
+       teleray_glitch.   This  glitch  is  also  taken  to mean that it is not
+       possible to position the cursor on top of a  "magic  cookie",  that  to
+       erase  standout  mode  it is instead necessary to use delete and insert
+       line.  The ncurses implementation ignores this glitch.
+
+       The Beehive Superbee, which is unable to correctly transmit the  escape
+       or  control/C  characters,  has <STRONG>xsb</STRONG>, indicating that the f1 key is used
+       for escape and f2 for control/C.  (Only  certain  Superbees  have  this
+       problem,  depending on the ROM.)  Note that in older terminfo versions,
+       this capability was called "beehive_glitch"; it is now "no_esc_ctl_c".

+
+
+</PRE><H3><a name="h3-Pitfalls-of-Long-Entries">Pitfalls of Long Entries</a></H3><PRE>
+       Long  terminfo  entries are unlikely to be a problem; to date, no entry
+       has  even  approached  terminfo's   4096-byte   string-table   maximum.
+       Unfortunately,  the termcap translations are much more strictly limited
+       (to 1023 bytes), thus termcap translations of long terminfo entries can
+       cause problems.
+
+       The  man  pages  for  4.3BSD and older versions of <STRONG>tgetent</STRONG> instruct the
+       user to allocate a 1024-byte buffer for the termcap entry.   The  entry
+       gets  null-terminated by the termcap library, so that makes the maximum
+       safe length for a termcap entry 1k-1 (1023) bytes.  Depending  on  what
+       the  application  and the termcap library being used does, and where in
+       the termcap file the terminal type that <STRONG>tgetent</STRONG> is  searching  for  is,
+       several bad things can happen.
+
+       Some  termcap libraries print a warning message or exit if they find an
+       entry that's longer than 1023 bytes; others do not; others truncate the
+       entries  to  1023  bytes.  Some application programs allocate more than
+       the recommended 1K for the termcap entry; others do not.
+
+       Each termcap entry has two important sizes associated with  it:  before
+       "tc"  expansion, and after "tc" expansion.  "tc" is the capability that
+       tacks on another termcap entry to the end of the current one, to add on
+       its capabilities.  If a termcap entry does not use the "tc" capability,
+       then of course the two lengths are the same.
+
+       The "before tc expansion" length is the most important one, because  it
+       affects  more than just users of that particular terminal.  This is the
+       length of the entry as it exists in /etc/termcap, minus the  backslash-
+       newline pairs, which <STRONG>tgetent</STRONG> strips out while reading it.  Some termcap
+       libraries strip off the final newline, too (GNU termcap does not).  Now
+       suppose:
+
+       <STRONG>o</STRONG>   a termcap entry before expansion is more than 1023 bytes long,
+
+       <STRONG>o</STRONG>   and the application has only allocated a 1k buffer,
+
+       <STRONG>o</STRONG>   and  the termcap library (like the one in BSD/OS 1.1 and GNU) reads
+           the whole entry into the buffer, no matter what its length, to  see
+           if it is the entry it wants,
+
+       <STRONG>o</STRONG>   and  <STRONG>tgetent</STRONG>  is  searching  for a terminal type that either is the
+           long entry, appears in the termcap file after the  long  entry,  or
+           does  not  appear in the file at all (so that <STRONG>tgetent</STRONG> has to search
+           the whole termcap file).
+
+       Then <STRONG>tgetent</STRONG> will overwrite memory, perhaps  its  stack,  and  probably
+       core   dump   the  program.   Programs  like  telnet  are  particularly
+       vulnerable; modern telnets pass along values  like  the  terminal  type
+       automatically.   The  results  are almost as undesirable with a termcap
+       library, like SunOS 4.1.3 and Ultrix 4.4, that prints warning  messages
+       when  it  reads  an  overly  long  termcap entry.  If a termcap library
+       truncates long entries, like OSF/1 3.0, it is immune to dying here  but
+       will return incorrect data for the terminal.
+
+       The  "after  tc  expansion"  length  will  have a similar effect to the
+       above, but only for people who actually set TERM to that terminal type,
+       since  <STRONG>tgetent</STRONG>  only  does "tc" expansion once it is found the terminal
+       type it was looking for, not while searching.
+
+       In summary, a termcap entry that is longer than 1023 bytes  can  cause,
+       on  various  combinations of termcap libraries and applications, a core
+       dump, warnings, or incorrect operation.  If it is too long even  before
+       "tc"  expansion,  it will have this effect even for users of some other
+       terminal types and users whose TERM variable does not  have  a  termcap
+       entry.
+
+       When  in  -C (translate to termcap) mode, the <STRONG>ncurses</STRONG> implementation of
+       <STRONG><A HREF="tic.1m.html">tic(1m)</A></STRONG> issues warning messages when the pre-tc  length  of  a  termcap
+       translation  is  too  long.  The -c (check) option also checks resolved
+       (after tc expansion) lengths.

+       It is not wise to count  on  portability  of  binary  terminfo  entries

+       Searching    for   terminal   descriptions   in   <STRONG>$HOME/.terminfo</STRONG>   and
+       TERMINFO_DIRS is not supported by older implementations.
+
+       Some SVr4 <STRONG>curses</STRONG> implementations, and all  previous  to  SVr4,  do  not
+       interpret the %A and %O operators in parameter strings.
+
+       SVr4/XPG4  do  not  specify  whether <STRONG>msgr</STRONG> licenses movement while in an
+       alternate-character-set mode (such modes may, among other  things,  map
+       CR  and  NL  to  characters  that  do  not trigger local motions).  The
+       <STRONG>ncurses</STRONG> implementation ignores <STRONG>msgr</STRONG> in <STRONG>ALTCHARSET</STRONG>  mode.   This  raises
+       the  possibility  that  an  XPG4  implementation  making  the  opposite
+       interpretation may need terminfo entries made for <STRONG>ncurses</STRONG> to have  <STRONG>msgr</STRONG>
+       turned off.
+
+       The <STRONG>ncurses</STRONG> library handles insert-character and insert-character modes

+       documented in SVr4 or the XSI Curses standard.  They are  deduced  from
+       the documentation for the AT&amp;T 505 terminal.
+
+       Be  careful  assigning the <STRONG>kmous</STRONG> capability.  The <STRONG>ncurses</STRONG> library wants
+       to interpret it as <STRONG>KEY_MOUSE</STRONG>, for use by terminals and  emulators  like
+       xterm  that can return mouse-tracking information in the keyboard-input
+       stream.

+       X/Open Curses does not mention  italics.   Portable  applications  must

+       includes the <EM>no</EM><STRONG>_</STRONG><EM>color</EM><STRONG>_</STRONG><EM>video</EM> (ncv) capability.   The  32768  mask  value
+       used  for  italics with ncv can be confused with an absent or cancelled
+       ncv.  If italics should work with colors, then the ncv  value  must  be
+       specified, even if it is zero.
+
+       Different  commercial  ports  of  terminfo and curses support different
+       subsets of the XSI  Curses  standard  and  (in  some  cases)  different
+       extension sets.  Here is a summary, accurate as of October 1995:
+
+       <STRONG>o</STRONG>   <STRONG>SVR4,</STRONG> <STRONG>Solaris,</STRONG> <STRONG>ncurses</STRONG> -- These support all SVr4 capabilities.
+
+       <STRONG>o</STRONG>   <STRONG>SGI</STRONG> -- Supports the SVr4 set, adds one undocumented extended string
+           capability (<STRONG>set_pglen</STRONG>).
+
+       <STRONG>o</STRONG>   <STRONG>SVr1,</STRONG> <STRONG>Ultrix</STRONG> -- These  support  a  restricted  subset  of  terminfo
+           capabilities.   The  booleans  end with <STRONG>xon_xoff</STRONG>; the numerics with
+           <STRONG>width_status_line</STRONG>; and the strings with <STRONG>prtr_non</STRONG>.
+
+       <STRONG>o</STRONG>   <STRONG>HP/UX</STRONG> -- Supports the  SVr1  subset,  plus  the  SVr[234]  numerics
+           <STRONG>num_labels</STRONG>,   <STRONG>label_height</STRONG>,  <STRONG>label_width</STRONG>,  plus  function  keys  11
+           through 63, plus <STRONG>plab_norm</STRONG>,  <STRONG>label_on</STRONG>,  and  <STRONG>label_off</STRONG>,  plus  some
+           incompatible extensions in the string table.
+
+       <STRONG>o</STRONG>   <STRONG>AIX</STRONG>  -- Supports the SVr1 subset, plus function keys 11 through 63,
+           plus a number of incompatible string table extensions.
+
+       <STRONG>o</STRONG>   <STRONG>OSF</STRONG> -- Supports both the SVr4 set and the AIX extensions.

+       The <STRONG>tic</STRONG> command translates a <STRONG>terminfo</STRONG>  file  from  source  format  into
+       compiled  format.   The  compiled  format is necessary for use with the
+       library routines in <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>.
+
+       As described in <STRONG><A HREF="term.5.html">term(5)</A></STRONG>, the database may be either  a  directory  tree
+       (one  file  per  terminal  entry)  or a hashed database (one record per
+       entry).  The <STRONG>tic</STRONG> command writes only one type of  entry,  depending  on
+       how it was built:
+
+       <STRONG>o</STRONG>   For    directory    trees,    the    top-level   directory,   e.g.,
+           /usr/share/terminfo, specifies the location of the database.
+
+       <STRONG>o</STRONG>   For hashed databases, a filename is needed.  If the given  file  is
+           not  found  by  that  name,  but  can be found by adding the suffix
+           ".db", then that is used.
+
+           The default name for the hashed database is the same as the default
+           directory name (only adding a ".db" suffix).
+
+       In  either  case  (directory  or  hashed database), <STRONG>tic</STRONG> will create the
+       container if it does not exist.  For a directory,  this  would  be  the
+       "terminfo" leaf, versus a "terminfo.db" file.
+
+       The  results  are  normally  placed  in  the  system  terminfo database
+       <STRONG>/usr/share/terminfo</STRONG>.  The compiled terminal description can  be  placed
+       in a different terminfo database.  There are two ways to achieve this:
+
+       <STRONG>o</STRONG>   First,  you  may override the system default either by using the <STRONG>-o</STRONG>
+           option,  or  by  setting  the  variable  <STRONG>TERMINFO</STRONG>  in  your   shell
+           environment to a valid database location.
+
+       <STRONG>o</STRONG>   Secondly,  if  <STRONG>tic</STRONG>  cannot  write  in  <EM>/usr/share/terminfo</EM>  or  the
+           location specified using your TERMINFO variable, it looks  for  the
+           directory  <EM>$HOME/.terminfo</EM> (or hashed database <EM>$HOME/.terminfo.db)</EM>;
+           if that location exists, the entry is placed there.
+
+       Libraries  that  read  terminfo  entries  are  expected  to  check   in
+       succession
+
+       <STRONG>o</STRONG>   a location specified with the TERMINFO environment variable,
+
+       <STRONG>o</STRONG>   <EM>$HOME/.terminfo</EM>,
+
+       <STRONG>o</STRONG>   directories listed in the TERMINFO_DIRS environment variable,
+
+       <STRONG>o</STRONG>   a compiled-in list of directories (no default value), and
+
+       <STRONG>o</STRONG>   the system terminfo database (<EM>/usr/share/terminfo</EM>).
+
+

+       This  is the same program as infotocap and captoinfo; usually those are
+       linked to, or copied from this program:
+
+       <STRONG>o</STRONG>   When invoked as infotocap, tic sets the <STRONG>-I</STRONG> option.
+
+       <STRONG>o</STRONG>   When invoked as captoinfo, tic sets the <STRONG>-C</STRONG> option.
+
+
+</PRE><H3><a name="h3-OPTIONS">OPTIONS</a></H3><PRE>
+       <STRONG>-0</STRONG>     restricts the output to a single line
+
+       <STRONG>-1</STRONG>     restricts the output to a single column
+
+       <STRONG>-a</STRONG>     tells <STRONG>tic</STRONG>  to  retain  commented-out  capabilities  rather  than
+              discarding  them.   Capabilities are commented by prefixing them
+              with a period.  This sets the <STRONG>-x</STRONG> option, because it  treats  the
+              commented-out  entries  as user-defined names.  If the source is
+              termcap, accept the 2-character names  required  by  version  6.
+              Otherwise these are ignored.
+
+       <STRONG>-C</STRONG>     Force  source translation to termcap format.  Note: this differs
+              from the <STRONG>-C</STRONG> option of <STRONG><A HREF="infocmp.1m.html">infocmp(1m)</A></STRONG> in that  it  does  not  merely
+              translate capability names, but also translates terminfo strings
+              to termcap format.  Capabilities that are not  translatable  are
+              left  in  the entry under their terminfo names but commented out
+              with two preceding dots.  The actual  format  used  incorporates
+              some  improvements  for escaped characters from terminfo format.
+              For a stricter BSD-compatible translation, add the <STRONG>-K</STRONG> option.
+
+              If this is combined with <STRONG>-c</STRONG>,  <STRONG>tic</STRONG>  makes  additional  checks  to
+              report  cases  where  the  terminfo  values do not have an exact
+              equivalent in termcap form.  For example:
+
+              <STRONG>o</STRONG>   <STRONG>sgr</STRONG> usually will not  convert,  because  termcap  lacks  the
+                  ability  to  work with more than two parameters, and because
+                  termcap lacks many of the arithmetic/logical operators  used
+                  in terminfo.
+
+              <STRONG>o</STRONG>   capabilities  with more than one delay or with delays before
+                  the end of the string will not convert completely.
+
+       <STRONG>-c</STRONG>     tells <STRONG>tic</STRONG> to  only  check  <EM>file</EM>  for  errors,  including  syntax
+              problems  and  bad  use-links.  If you specify <STRONG>-C</STRONG> (<STRONG>-I</STRONG>) with this
+              option, the code will print warnings about entries which,  after
+              use  resolution, are more than 1023 (4096) bytes long.  Due to a
+              fixed buffer length in older termcap libraries, as well as buggy
+              checking  for  the  buffer  length  (and  a  documented limit in
+              terminfo),  these  entries  may  cause  core  dumps  with  other
+              implementations.
+
+              <STRONG>tic</STRONG>  checks  string  capabilities  to  ensure  that  those  with
+              parameters will be valid expressions.  It does this  check  only
+              for  the predefined string capabilities; those which are defined
+              with the <STRONG>-x</STRONG> option are ignored.
+
+       <STRONG>-D</STRONG>     tells <STRONG>tic</STRONG> to print the database locations that it  knows  about,
+              and exit.  The first location shown is the one to which it would
+              write compiled terminal descriptions.  If <STRONG>tic</STRONG>  is  not  able  to
+              find  a  writable  database  location  according  to  the  rules
+              summarized above, it will print a diagnostic and  exit  with  an
+              error rather than printing a list of database locations.
+
+       <STRONG>-e</STRONG> <EM>names</EM>
+              Limit  writes  and translations to the following comma-separated
+              list of terminals.  If any name or alias of a  terminal  matches
+              one  of  the  names  in  the  list, the entry will be written or
+              translated as normal.  Otherwise no output will be generated for
+              it.   The  option  value is interpreted as a file containing the
+              list if it contains a '/'.  (Note:  depending  on  how  tic  was
+              compiled, this option may require <STRONG>-I</STRONG> or <STRONG>-C</STRONG>.)
+
+       <STRONG>-f</STRONG>     Display     complex     terminfo     strings    which    contain
+              if/then/else/endif expressions indented for readability.
+
+       <STRONG>-G</STRONG>     Display constant literals in  decimal  form  rather  than  their
+              character equivalents.
+
+       <STRONG>-g</STRONG>     Display  constant  character literals in quoted form rather than
+              their decimal equivalents.
+
+       <STRONG>-I</STRONG>     Force source translation to terminfo format.
+
+       <STRONG>-K</STRONG>     Suppress some longstanding ncurses extensions to termcap format,
+              e.g., "\s" for space.
+
+       <STRONG>-L</STRONG>     Force  source  translation  to  terminfo format using the long C
+              variable names listed in &lt;<STRONG>term.h</STRONG>&gt;
+
+       <STRONG>-N</STRONG>     Disable smart defaults.  Normally, when translating from termcap
+              to  terminfo,  the  compiler makes a number of assumptions about
+              the   defaults    of    string    capabilities    <STRONG>reset1_string</STRONG>,
+              <STRONG>carriage_return</STRONG>,  <STRONG>cursor_left</STRONG>, <STRONG>cursor_down</STRONG>, <STRONG>scroll_forward</STRONG>, <STRONG>tab</STRONG>,
+              <STRONG>newline</STRONG>, <STRONG>key_backspace</STRONG>, <STRONG>key_left</STRONG>, and <STRONG>key_down</STRONG>, then attempts to
+              use  obsolete termcap capabilities to deduce correct values.  It
+              also normally suppresses output of obsolete termcap capabilities
+              such  as <STRONG>bs</STRONG>.  This option forces a more literal translation that
+              also preserves the obsolete capabilities.
+
+       <STRONG>-o</STRONG><EM>dir</EM>  Write compiled entries to given  database  location.   Overrides
+              the TERMINFO environment variable.
+
+       <STRONG>-Q</STRONG><EM>n</EM>    Rather  than  show  source  in terminfo (text) format, print the
+              compiled  (binary)  format  in  hexadecimal  or   base64   form,
+              depending on the option's value:
+
+               1  hexadecimal
+
+               2  base64
+
+               3  hexadecimal and base64
+
+       <STRONG>-q</STRONG>     Suppress  comments  and  blank  lines  when  showing  translated
+              source.
+
+       <STRONG>-R</STRONG><EM>subset</EM>
+              Restrict output to a given subset.  This option is for use  with
+              archaic  versions of terminfo like those on SVr1, Ultrix, or HP-

+              and  outright  broken  ports  like  AIX  3.x that have their own
+              extensions incompatible with SVr4/XSI.   Available  subsets  are
+              "SVr1",  "Ultrix",  "HP",  "BSD"  and "AIX"; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for

+       <STRONG>-r</STRONG>     Force  entry  resolution  (so  there   are   no   remaining   tc
+              capabilities)  even  when  doing  translation to termcap format.
+              This may be needed if you are preparing a  termcap  file  for  a
+              termcap  library (such as GNU termcap through version 1.3 or BSD
+              termcap  through  4.3BSD)  that  does  not  handle  multiple  tc
+              capabilities per entry.
+
+       <STRONG>-s</STRONG>     Summarize  the  compile  by  showing  the database location into
+              which entries are written, and the number of entries  which  are
+              compiled.
+
+       <STRONG>-T</STRONG>     eliminates  size-restrictions  on  the  generated text.  This is
+              mainly useful for  testing  and  analysis,  since  the  compiled
+              descriptions  are  limited  (e.g.,  1023  for  termcap, 4096 for
+              terminfo).
+
+       <STRONG>-t</STRONG>     tells <STRONG>tic</STRONG> to discard commented-out capabilities.  Normally  when
+              translating    from    terminfo   to   termcap,   untranslatable
+              capabilities are commented-out.
+
+       <STRONG>-U</STRONG>   tells <STRONG>tic</STRONG> to not post-process the data after  parsing  the  source
+            file.  Normally, it infers data which is commonly missing in older
+            terminfo data, or in termcaps.
+
+       <STRONG>-V</STRONG>   reports the version of ncurses which was used in this program, and
+            exits.
+
+       <STRONG>-v</STRONG><EM>n</EM>  specifies that (verbose) output be written to standard error trace
+            information showing <STRONG>tic</STRONG>'s progress.
+
+            The optional parameter <EM>n</EM> is a  number  from  1  to  9,  inclusive,
+            indicating the desired level of detail of information.
+
+            <STRONG>o</STRONG>   If  ncurses  is  built  without  tracing support, the optional
+                parameter is ignored.
+
+            <STRONG>o</STRONG>   If <EM>n</EM> is omitted, the default level is 1.
+
+            <STRONG>o</STRONG>   If <EM>n</EM> is specified and greater than 1, the level of  detail  is
+                increased,   and   the   output   is   written  (with  tracing
+                information) to the "trace" file.
+
+            The debug flag levels are as follows:
+
+            1   Names of files created and linked
+
+            2   Information related to the "use" facility
+

+

+            wrapped.  Use the <STRONG>-W</STRONG> option to do this.
+
+            If  you specify both <STRONG>-f</STRONG> and <STRONG>-W</STRONG> options, the latter is ignored when
+            <STRONG>-f</STRONG> has already split the line.
+
+       <STRONG>-w</STRONG><EM>n</EM>  specifies the width of the output.  The parameter is optional.  If
+            it is omitted, it defaults to 60.
+
+       <STRONG>-x</STRONG>   Treat  unknown  capabilities  as  user-defined (see <STRONG>user_caps(5)</STRONG>).
+            That is, if you supply  a  capability  name  which  <STRONG>tic</STRONG>  does  not
+            recognize, it will infer its type (boolean, number or string) from
+            the syntax and make an  extended  table  entry  for  that.   User-
+            defined  capability strings whose name begins with "k" are treated

+       System V Release 2 provided  a  <STRONG>tic</STRONG>  utility.   It  accepted  a  single
+       option:  <STRONG>-v</STRONG>  (optionally  followed  by  a  number).   According to Ross
+       Ridge's comment in <EM>mytinfo</EM>, this version of <STRONG>tic</STRONG> was unable to represent
+       cancelled capabilities.
+
+       System  V  Release 3 provided a different <STRONG>tic</STRONG> utility, written by Pavel
+       Curtis, (originally named "compile" in <EM>pcurses</EM>).  This added an  option
+       <STRONG>-c</STRONG>  to check the file for errors, with the caveat that errors in "use="
+       links would not be reported.  System  V  Release  3  documented  a  few
+       warning  messages  which  did not appear in <EM>pcurses</EM>.  While the program
+       itself was changed  little  as  development  continued  with  System  V
+       Release  4,  the  table  of capabilities grew from 180 (<EM>pcurses</EM>) to 464
+       (Solaris).
+
+       In early development of ncurses (1993), Zeyd Ben-Halim used  the  table
+       from  <EM>mytinfo</EM>  to  extend  the  <EM>pcurses</EM>  table to 469 capabilities (456
+       matched SVr4, 8 were only in SVr4, 13 were not in SVr4).  Of those  13,
+       11  were  ultimately  discarded  (perhaps  to match the draft of X/Open
+       Curses).  The exceptions were <STRONG>memory_lock_above</STRONG> and <STRONG>memory_unlock</STRONG>  (see
+       <STRONG><A HREF="user_caps.5.html">user_caps(5)</A></STRONG>).
+
+       Eric  Raymond  incorporated  parts of <EM>mytinfo</EM> into ncurses to implement
+       the termcap-to-terminfo source conversion, and extended that  to  begin
+       development of the corresponding terminfo-to-termcap source conversion,
+       Thomas Dickey completed that development over  the  course  of  several
+       years.
+
+       In  1999,  Thomas  Dickey  added  the <STRONG>-x</STRONG> option to support user-defined
+       capabilities.
+
+       In 2010, Roy Marples provided a <STRONG>tic</STRONG> program and  terminfo  library  for
+       NetBSD.   That  implementation  adapts  several  features from ncurses,
+       including <STRONG>tic</STRONG>'s <STRONG>-x</STRONG> option.
+
+       The <STRONG>-c</STRONG> option tells <STRONG>tic</STRONG> to check for problems in  the  terminfo  source
+       file.  Continued development provides additional checks:
+
+       <STRONG>o</STRONG>   <EM>pcurses</EM> had 8 warnings
+
+       <STRONG>o</STRONG>   ncurses in 1996 had 16 warnings
+
+       <STRONG>o</STRONG>   Solaris (SVr4) curses has 28 warnings
+
+       <STRONG>o</STRONG>   NetBSD tic in 2019 has 19 warnings.
+
+       <STRONG>o</STRONG>   ncurses in 2019 has 96 warnings
+
+       The checking done in ncurses' <STRONG>tic</STRONG> helps with the conversion to termcap,
+       as well as pointing out errors and inconsistencies.  It is also used to
+       ensure  consistency  with the user-defined capabilities.  There are 527
+       distinct capabilities in ncurses' terminal database; 128 of  those  are
+       user-defined.

+       X/Open  Curses, Issue 7 (2009) provides a brief description of <STRONG>tic</STRONG>.  It
+       lists one option: <STRONG>-c</STRONG>.  The omission of <STRONG>-v</STRONG> is  unexpected.   The  change
+       history  states  that  the  description  is  derived  from True64 UNIX.
+       According to its manual  pages,  that  system  also  supported  the  <STRONG>-v</STRONG>
+       option.
+
+       Shortly  after  Issue  7  was  released, Tru64 was discontinued.  As of
+       2019, the surviving implementations of <STRONG>tic</STRONG> are  SVr4  (AIX,  HP-UX  and
+       Solaris), ncurses and NetBSD curses.  The SVr4 <STRONG>tic</STRONG> programs all support
+       the <STRONG>-v</STRONG> option.  The NetBSD <STRONG>tic</STRONG> program follows X/Open's  documentation,
+       omitting the <STRONG>-v</STRONG> option.
+
+       The  X/Open  rationale  states  that  some  implementations of <STRONG>tic</STRONG> read
+       terminal descriptions from the standard input if the <EM>file</EM> parameter  is
+       omitted.   None of these implementations do that.  Further, it comments
+       that some  may  choose  to  read  from  "./terminfo.src"  but  that  is
+       obsolescent  behavior  from SVr2, and is not (for example) a documented
+       feature of SVr3.
+
+
+</PRE><H3><a name="h3-COMPATIBILITY">COMPATIBILITY</a></H3><PRE>
+       There is  some  evidence  that  historic  <STRONG>tic</STRONG>  implementations  treated
+       description  fields with no whitespace in them as additional aliases or
+       short names.  This <STRONG>tic</STRONG>  does  not  do  that,  but  it  does  warn  when
+       description fields may be treated that way and check them for dangerous
+       characters.
+
+
+</PRE><H3><a name="h3-EXTENSIONS">EXTENSIONS</a></H3><PRE>
+       Unlike the SVr4 <STRONG>tic</STRONG> command, this implementation can  actually  compile
+       termcap  sources.   In fact, entries in terminfo and termcap syntax can
+       be mixed in a single source file.  See  <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>  for  the  list  of
+       termcap names taken to be equivalent to terminfo names.
+
+       The  SVr4  manual  pages  are not clear on the resolution rules for <STRONG>use</STRONG>
+       capabilities.   This  implementation  of  <STRONG>tic</STRONG>  will  find  <STRONG>use</STRONG>  targets
+       anywhere  in  the  source  file, or anywhere in the file tree rooted at
+       <STRONG>TERMINFO</STRONG> (if <STRONG>TERMINFO</STRONG> is defined), or  in  the  user's  <EM>$HOME/.terminfo</EM>
+       database  (if  it  exists),  or (finally) anywhere in the system's file
+       tree of compiled entries.
+
+       The error messages from this <STRONG>tic</STRONG> have the same format as  GNU  C  error
+       messages, and can be parsed by GNU Emacs's compile facility.
+
+       Aside from <STRONG>-c</STRONG> and <STRONG>-v</STRONG>, options are not portable:
+
+       <STRONG>o</STRONG>   Most of tic's options are not supported by SVr4 <STRONG>tic</STRONG>:
+
+           <STRONG>-0</STRONG> <STRONG>-1</STRONG> <STRONG>-C</STRONG> <STRONG>-G</STRONG> <STRONG>-I</STRONG> <STRONG>-N</STRONG> <STRONG>-R</STRONG> <STRONG>-T</STRONG> <STRONG>-V</STRONG> <STRONG>-a</STRONG> <STRONG>-e</STRONG> <STRONG>-f</STRONG> <STRONG>-g</STRONG> <STRONG>-o</STRONG> <STRONG>-r</STRONG> <STRONG>-s</STRONG> <STRONG>-t</STRONG> <STRONG>-x</STRONG>
+
+       <STRONG>o</STRONG>   The NetBSD <STRONG>tic</STRONG>  supports a few of the ncurses options
+
+           <STRONG>-a</STRONG> <STRONG>-o</STRONG> <STRONG>-x</STRONG>
+
+           and  adds  <STRONG>-S</STRONG>  (a feature which does the same thing as infocmp's <STRONG>-e</STRONG>
+           and <STRONG>-E</STRONG> options).
+
+       The SVr4 <STRONG>-c</STRONG> mode does not report bad "use=" links.
+
+       System V does  not  compile  entries  to  or  read  entries  from  your
+       <EM>$HOME/.terminfo</EM> database unless TERMINFO is explicitly set to it.

+       header will be issued as each directory is entered.
+
+       There are other options intended for use by terminfo file maintainers:
+
+       <STRONG>-a</STRONG>     report  on  all  of  the  terminal databases which ncurses would
+              search, rather than only the first one that it finds.
+
+              If the <STRONG>-s</STRONG> is also given,  <STRONG>toe</STRONG>  adds  a  column  to  the  report,
+              showing (like <STRONG>conflict(1)</STRONG>) which entries which belong to a given
+              terminal database.  An "*" marks entries which differ,  and  "+"
+              marks equivalent entries.
+
+              Without  the <STRONG>-s</STRONG> option, <STRONG>toe</STRONG> does not attempt to merge duplicates
+              in its report
+
+       <STRONG>-s</STRONG>     sort the output by the entry names.
+
+       <STRONG>-u</STRONG> <EM>file</EM>
+              says  to  write  a  report  to  the  standard  output,   listing
+              dependencies  in  the  given  terminfo/termcap source file.  The
+              report condenses the "use" relation: each line consists  of  the
+              primary  name  of a terminal that has use capabilities, followed
+              by a colon, followed by the whitespace-separated  primary  names
+              of all terminals which occur in those use capabilities, followed
+              by a newline
+
+       <STRONG>-U</STRONG> <EM>file</EM>
+              says to write a report to the standard output,  listing  reverse
+              dependencies  in  the  given  terminfo/termcap source file.  The
+              report reverses the "use" relation: each line  consists  of  the
+              primary  name  of  a  terminal  that occurs in use capabilities,
+              followed  by  a  colon,  followed  by  the  whitespace-separated
+              primary names of all terminals which depend on it, followed by a
+              newline.
+
+       <STRONG>-v</STRONG><EM>n</EM>    specifies that (verbose) output be written  to  standard  error,
+              showing <STRONG>toe</STRONG>'s progress.
+
+              The  optional  parameter <EM>n</EM> is a number from 1 to 10, interpreted
+              as for <STRONG><A HREF="tic.1m.html">tic(1m)</A></STRONG>.  If ncurses is built  without  tracing  support,
+              the optional parameter is ignored.
+
+       <STRONG>-V</STRONG>     reports  the  version of ncurses which was used in this program,

+       The  <STRONG>tput</STRONG>  utility  uses  the  <STRONG>terminfo</STRONG>  database to make the values of
+       terminal-dependent capabilities and information available to the  shell
+       (see  <STRONG>sh(1)</STRONG>),  to  initialize or reset the terminal, or return the long
+       name of the requested terminal  type.   The  result  depends  upon  the
+       capability's type:
+
+          string
+               <STRONG>tput</STRONG>  writes  the  string  to the standard output.  No trailing
+               newline is supplied.
+
+          integer
+               <STRONG>tput</STRONG> writes the decimal value to the standard  output,  with  a
+               trailing newline.
+
+          boolean
+               <STRONG>tput</STRONG>  simply sets the exit code (<STRONG>0</STRONG> for TRUE if the terminal has
+               the capability, <STRONG>1</STRONG> for FALSE if it does not), and writes nothing
+               to the standard output.
+
+       Before  using  a value returned on the standard output, the application
+       should test the exit code (e.g., <STRONG>$?</STRONG>, see <STRONG>sh(1)</STRONG>) to be  sure  it  is  <STRONG>0</STRONG>.
+       (See  the <STRONG>EXIT</STRONG> <STRONG>CODES</STRONG> and <STRONG>DIAGNOSTICS</STRONG> sections.)  For a complete list of
+       capabilities and the <EM>capname</EM> associated with each, see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.
+
+
+</PRE><H3><a name="h3-Options">Options</a></H3><PRE>
+       <STRONG>-S</STRONG>     allows more than one capability per  invocation  of  <STRONG>tput</STRONG>.   The
+              capabilities  must  be  passed  to  <STRONG>tput</STRONG> from the standard input
+              instead of from  the  command  line  (see  example).   Only  one
+              <EM>capname</EM>  is allowed per line.  The <STRONG>-S</STRONG> option changes the meaning
+              of the <STRONG>0</STRONG> and <STRONG>1</STRONG> boolean and string exit codes (see the EXIT CODES
+              section).
+
+              Because  some capabilities may use <EM>string</EM> parameters rather than
+              <EM>numbers</EM>, <STRONG>tput</STRONG> uses a table and the presence of parameters in its
+              input  to  decide whether to use <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG>, and how to interpret
+              the parameters.
+
+       <STRONG>-T</STRONG><EM>type</EM> indicates  the  <EM>type</EM>  of  terminal.   Normally  this  option  is
+              unnecessary,  because  the default is taken from the environment
+              variable <STRONG>TERM</STRONG>.  If <STRONG>-T</STRONG> is specified,  then  the  shell  variables
+              <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> will also be ignored.
+
+       <STRONG>-V</STRONG>     reports  the  version of ncurses which was used in this program,
+              and exits.
+
+       <STRONG>-x</STRONG>     do not attempt to clear the terminal's scrollback  buffer  using
+              the extended "E3" capability.
+
+
+</PRE><H3><a name="h3-Commands">Commands</a></H3><PRE>
+       A few commands (<STRONG>init</STRONG>, <STRONG>reset</STRONG> and <STRONG>longname</STRONG>) are special; they are defined
+       by the <STRONG>tput</STRONG> program.  The others are the names of <EM>capabilities</EM> from the
+       terminal  database  (see  <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>  for  a list).  Although <STRONG>init</STRONG> and
+       <STRONG>reset</STRONG> resemble capability names,  <STRONG>tput</STRONG>  uses  several  capabilities  to
+       perform these special functions.
+
+       <EM>capname</EM>
+              indicates the capability from the terminal database.
+
+              If  the  capability  is  a  string  that  takes  parameters, the
+              arguments following the capability will be  used  as  parameters
+              for the string.
+
+              Most  parameters  are numbers.  Only a few terminal capabilities
+              require string parameters; <STRONG>tput</STRONG> uses a table to decide which  to
+              pass  as  strings.   Normally <STRONG>tput</STRONG> uses <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG> to perform the
+              substitution.  If no parameters are given  for  the  capability,
+              <STRONG>tput</STRONG> writes the string without performing the substitution.
+
+       <STRONG>init</STRONG>   If  the terminal database is present and an entry for the user's
+              terminal exists (see <STRONG>-T</STRONG><EM>type</EM>, above), the following will occur:
+
+              (1)  first, <STRONG>tput</STRONG> retrieves the current  terminal  mode  settings
+                   for your terminal.  It does this by successively testing
+
+                   <STRONG>o</STRONG>   the standard error,
+
+                   <STRONG>o</STRONG>   standard output,
+
+                   <STRONG>o</STRONG>   standard input and
+
+                   <STRONG>o</STRONG>   ultimately "/dev/tty"
+
+                   to   obtain  terminal  settings.   Having  retrieved  these
+                   settings, <STRONG>tput</STRONG> remembers which file descriptor to use  when
+                   updating settings.
+
+              (2)  if  the  window  size cannot be obtained from the operating
+                   system, but the terminal description (or environment, e.g.,
+                   <STRONG>LINES</STRONG>  and  <STRONG>COLUMNS</STRONG>  variables  specify  this),  update the
+                   operating system's notion of the window size.
+
+              (3)  the terminal modes will be updated:
+
+                   <STRONG>o</STRONG>   any delays (e.g., newline) specified in the entry  will
+                       be set in the tty driver,
+
+                   <STRONG>o</STRONG>   tabs  expansion  will  be turned on or off according to
+                       the specification in the entry, and
+
+                   <STRONG>o</STRONG>   if tabs are not expanded, standard  tabs  will  be  set
+                       (every 8 spaces).
+
+              (4)  if  present,  the terminal's initialization strings will be
+                   output as detailed in the <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> section on  <EM>Tabs</EM>  <EM>and</EM>
+                   <EM>Initialization</EM>,
+
+              (5)  output is flushed.
+
+              If  an  entry does not contain the information needed for any of
+              these activities, that activity will silently be skipped.
+
+       <STRONG>reset</STRONG>  This is similar to <STRONG>init</STRONG>, with two differences:
+
+              (1)  before any other initialization, the terminal modes will be
+                   reset to a "sane" state:
+
+                   <STRONG>o</STRONG>   set cooked and echo modes,
+
+                   <STRONG>o</STRONG>   turn off cbreak and raw modes,
+
+                   <STRONG>o</STRONG>   turn on newline translation and
+
+                   <STRONG>o</STRONG>   reset  any  unset  special  characters to their default
+                       values

+       <STRONG>tput</STRONG> handles the <STRONG>clear</STRONG>, <STRONG>init</STRONG> and <STRONG>reset</STRONG> commands  specially:  it  allows
+       for the possibility that it is invoked by a link with those names.
+
+       If  <STRONG>tput</STRONG>  is invoked by a link named <STRONG>reset</STRONG>, this has the same effect as
+       <STRONG>tput</STRONG> <STRONG>reset</STRONG>.  The  <STRONG><A HREF="tset.1.html">tset(1)</A></STRONG>  utility  also  treats  a  link  named  <STRONG>reset</STRONG>
+       specially.
+
+       Before ncurses 6.1, the two utilities were different from each other:
+
+       <STRONG>o</STRONG>   <STRONG>tset</STRONG>  utility  reset the terminal modes and special characters (not
+           done with <STRONG>tput</STRONG>).
+
+       <STRONG>o</STRONG>   On the other hand, <STRONG>tset</STRONG>'s repertoire of terminal  capabilities  for
+           resetting  the terminal was more limited, i.e., only <STRONG>reset_1string</STRONG>,
+           <STRONG>reset_2string</STRONG> and <STRONG>reset_file</STRONG>  in  contrast  to  the  tab-stops  and
+           margins which are set by this utility.
+
+       <STRONG>o</STRONG>   The  <STRONG>reset</STRONG>  program  is  usually an alias for <STRONG>tset</STRONG>, because of this
+           difference with resetting terminal modes and special characters.
+
+       With the changes made for ncurses 6.1, the <EM>reset</EM>  feature  of  the  two
+       programs is (mostly) the same.  A few differences remain:
+
+       <STRONG>o</STRONG>   The  <STRONG>tset</STRONG>  program  waits  one  second  when  resetting, in case it
+           happens to be a hardware terminal.
+
+       <STRONG>o</STRONG>   The two programs  write  the  terminal  initialization  strings  to
+           different  streams  (i.e.,  the  standard  error  for  <STRONG>tset</STRONG> and the
+           standard output for <STRONG>tput</STRONG>).
+
+           <STRONG>Note:</STRONG>  although  these  programs  write   to   different   streams,
+           redirecting  their output to a file will capture only part of their
+           actions.  The changes to the terminal modes  are  not  affected  by
+           redirecting the output.
+
+       If  <STRONG>tput</STRONG>  is  invoked by a link named <STRONG>init</STRONG>, this has the same effect as
+       <STRONG>tput</STRONG> <STRONG>init</STRONG>.  Again, you are less likely to use that link because another
+       program named <STRONG>init</STRONG> has a more well-established use.

+       <STRONG><A HREF="curs_terminfo.3x.html">setupterm(3x)</A></STRONG> to obtain the terminal size:
+
+       <STRONG>o</STRONG>   first, it gets the size from the terminal database (which generally

+           window size)
+
+       <STRONG>o</STRONG>   then  it  asks  the operating system for the terminal's size (which

+           support <EM>NAWS</EM>: negotiations about window size).
+

+       The  <STRONG>tput</STRONG>  command  was begun by Bill Joy in 1980.  The initial version
+       only cleared the screen.
+
+       AT&amp;T System V provided a different <STRONG>tput</STRONG> command:
+
+       <STRONG>o</STRONG>   SVr2 provided  a  rudimentary  <STRONG>tput</STRONG>  which  checked  the  parameter
+           against  each  predefined capability and returned the corresponding
+           value.  This  version  of  <STRONG>tput</STRONG>  did  not  use  <STRONG><A HREF="curs_terminfo.3x.html">tparm(3x)</A></STRONG>  for  the
+           capabilities which are parameterized.
+
+       <STRONG>o</STRONG>   SVr3 replaced that, a year later, by a more extensive program whose
+           <STRONG>init</STRONG> and <STRONG>reset</STRONG>  subcommands  (more  than  half  the  program)  were
+           incorporated  from  the  <STRONG>reset</STRONG>  feature of BSD <STRONG>tset</STRONG> written by Eric
+           Allman.
+
+       <STRONG>o</STRONG>   SVr4 added color initialization using the <STRONG>orig_colors</STRONG> and <STRONG>orig_pair</STRONG>
+           capabilities in the <STRONG>init</STRONG> subcommand.
+
+       Keith  Bostic  replaced  the  BSD  <STRONG>tput</STRONG>  command  in  1989  with  a new
+       implementation based on the AT&amp;T System V program <STRONG>tput</STRONG>.  Like the  AT&amp;T
+       program,  Bostic's  version accepted some parameters named for <EM>terminfo</EM>
+       capabilities (<STRONG>clear</STRONG>, <STRONG>init</STRONG>, <STRONG>longname</STRONG> and <STRONG>reset</STRONG>).   However  (because  he
+       had  only  <EM>termcap</EM>  available),  it  accepted  <EM>termcap</EM>  names for other
+       capabilities.  Also, Bostic's BSD <STRONG>tput</STRONG> did not modify the terminal  I/O
+       modes as the earlier BSD <STRONG>tset</STRONG> had done.
+
+       At the same time, Bostic added a shell script named "clear", which used
+       <STRONG>tput</STRONG> to clear the screen.
+
+       Both  of  these  appeared  in  4.4BSD,  becoming   the   "modern"   BSD
+       implementation of <STRONG>tput</STRONG>.
+
+       This  implementation of <STRONG>tput</STRONG> began from a different source than AT&amp;T or
+       BSD: Ross Ridge's <EM>mytinfo</EM> package, published  on  <EM>comp.sources.unix</EM>  in
+       December  1992.   Ridge's  program  made  more sophisticated use of the
+       terminal capabilities than the BSD program.   Eric  Raymond  used  that
+       <STRONG>tput</STRONG>  program  (and  other  parts  of <EM>mytinfo</EM>) in ncurses in June 1995.
+       Using the portions dealing with terminal  capabilities  almost  without
+       change,   Raymond   made  improvements  to  the  way  the  command-line
+       parameters were handled.
+
+
+</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
+       This implementation of <STRONG>tput</STRONG> differs from AT&amp;T  <STRONG>tput</STRONG>  in  two  important
+       areas:
+
+       <STRONG>o</STRONG>   <STRONG>tput</STRONG>  <EM>capname</EM>  writes  to  the standard output.  That need not be a
+           regular  terminal.   However,  the  subcommands  which   manipulate
+           terminal modes may not use the standard output.
+
+           The  AT&amp;T  implementation's  <STRONG>init</STRONG>  and  <STRONG>reset</STRONG>  commands use the BSD
+           (4.1c)  <STRONG>tset</STRONG>  source,  which  manipulates   terminal   modes.    It
+           successively  tries standard output, standard error, standard input
+           before falling back to "/dev/tty" and finally just assumes a 1200Bd
+           terminal.  When updating terminal modes, it ignores errors.
+
+           Until  changes made after ncurses 6.0, <STRONG>tput</STRONG> did not modify terminal
+           modes.  <STRONG>tput</STRONG> now uses a similar scheme, using functions shared with
+           <STRONG>tset</STRONG>  (and ultimately based on the 4.4BSD <STRONG>tset</STRONG>).  If it is not able
+           to open a terminal, e.g., when running in <STRONG>cron(1)</STRONG>, <STRONG>tput</STRONG> will return
+           an error.
+
+       <STRONG>o</STRONG>   AT&amp;T <STRONG>tput</STRONG> guesses the type of its <EM>capname</EM> operands by seeing if all
+           of the characters are numeric, or not.
+
+           Most implementations which provide support for <EM>capname</EM> operands use
+           the  <STRONG>tparm</STRONG>  function  to  expand  parameters  in it.  That function
+           expects a mixture of numeric and string parameters, requiring  <STRONG>tput</STRONG>
+           to know which type to use.
+
+           This  implementation  uses a table to determine the parameter types
+           for the standard <EM>capname</EM> operands, and an internal library function
+           to analyze nonstandard <EM>capname</EM> operands.
+
+           Besides  providing  more  reliable operation than AT&amp;T's utility, a
+           portability problem is introduced  by  this  analysis:  An  OpenBSD
+           developer  adapted  the  internal  library function from ncurses to
+           port NetBSD's  termcap-based  <STRONG>tput</STRONG>  to  terminfo.   That  had  been
+           modified  to  interpret  multiple  commands  on  a  line.  Portable
+           applications should not rely upon this feature; ncurses provides it
+           to support applications written specifically for OpenBSD.
+
+       This  implementation  (unlike  others)  can  accept  both  <EM>termcap</EM>  and
+       <EM>terminfo</EM> names for the <EM>capname</EM> feature, if <EM>termcap</EM> support is  compiled
+       in.   However,  the  predefined  <EM>termcap</EM>  and  <EM>terminfo</EM>  names have two
+       ambiguities in this case (and the <EM>terminfo</EM> name is assumed):
+
+       <STRONG>o</STRONG>   The <EM>termcap</EM> name <STRONG>dl</STRONG> corresponds to the <EM>terminfo</EM>  name  <STRONG>dl1</STRONG>  (delete
+           one line).
+           The  <EM>terminfo</EM>  name <STRONG>dl</STRONG> corresponds to the <EM>termcap</EM> name <STRONG>DL</STRONG> (delete a
+           given number of lines).
+
+       <STRONG>o</STRONG>   The <EM>termcap</EM> name <STRONG>ed</STRONG> corresponds to  the  <EM>terminfo</EM>  name  <STRONG>rmdc</STRONG>  (end
+           delete mode).
+           The  <EM>terminfo</EM>  name <STRONG>ed</STRONG> corresponds to the <EM>termcap</EM> name <STRONG>cd</STRONG> (clear to
+           end of screen).
+
+       The <STRONG>longname</STRONG> and <STRONG>-S</STRONG> options, and  the  parameter-substitution  features
+       used  in  the  <STRONG>cup</STRONG>  example,  were  not  supported in BSD curses before
+       4.3reno (1989) or in AT&amp;T/USL curses before SVr4 (1988).
+
+       IEEE  Std  1003.1/The  Open  Group    Base   Specifications   Issue   7
+       (POSIX.1-2008)  documents  only the operands for <STRONG>clear</STRONG>, <STRONG>init</STRONG> and <STRONG>reset</STRONG>.
+       There are a few interesting observations to make regarding that:
+
+       <STRONG>o</STRONG>   In this implementation, <STRONG>clear</STRONG> is part of the <EM>capname</EM> support.   The
+           others   (<STRONG>init</STRONG>   and   <STRONG>longname</STRONG>)  do  not  correspond  to  terminal
+           capabilities.
+
+       <STRONG>o</STRONG>   Other  implementations  of  <STRONG>tput</STRONG>  on  SVr4-based  systems  such  as
+           Solaris,  IRIX64  and  HPUX as well as others such as AIX and Tru64
+           provide support for <EM>capname</EM> operands.
+
+       <STRONG>o</STRONG>   A few platforms such as FreeBSD recognize termcap names rather than
+           terminfo capability names in their respective <STRONG>tput</STRONG> commands.  Since
+           2010, NetBSD's <STRONG>tput</STRONG> uses terminfo names.   Before  that,  it  (like
+           FreeBSD) recognized termcap names.

+           Beginning  in  2021,  FreeBSD uses the ncurses <STRONG>tput</STRONG>, configured for
+           both terminfo (tested first) and termcap (as a fallback).
+
+       Because (apparently) <EM>all</EM> of the certified Unix systems support the full
+       set  of  capability names, the reasoning for documenting only a few may
+       not be apparent.
+
+       <STRONG>o</STRONG>   X/Open Curses Issue 7 documents <STRONG>tput</STRONG> differently, with <EM>capname</EM>  and
+           the other features used in this implementation.
+
+       <STRONG>o</STRONG>   That  is,  there  are  two standards for <STRONG>tput</STRONG>: POSIX (a subset) and
+           X/Open Curses (the full implementation).  POSIX documents a  subset
+           to  avoid  the  complication  of  including  X/Open  Curses and the
+           terminal capabilities database.
+
+       <STRONG>o</STRONG>   While it is certainly possible to  write  a  <STRONG>tput</STRONG>  program  without
+           using   curses,   none   of   the   systems  which  have  a  curses
+           implementation provide a <STRONG>tput</STRONG> utility which does  not  provide  the
+           <EM>capname</EM> feature.
+
+       X/Open  Curses  Issue  7  (2009)  is  the  first  version  to  document
+       utilities.  However that part of X/Open Curses does not follow existing
+       practice (i.e., Unix features documented in SVID 3):
+
+       <STRONG>o</STRONG>   It  assigns exit code 4 to "invalid operand", which may be the same
+           as <EM>unknown</EM> <EM>capability</EM>.  For instance, the source code for  Solaris'
+           xcurses uses the term "invalid" in this case.
+
+       <STRONG>o</STRONG>   It  assigns  exit  code  255  to  a  numeric  variable  that is not
+           specified in the terminfo database.  That likely is a documentation
+           error,  confusing  the  <STRONG>-1</STRONG>  written  to  the standard output for an
+           absent or cancelled numeric value versus an (unsigned) exit code.
+
+       The various Unix systems (AIX, HPUX, Solaris) use the  same  exit-codes
+       as ncurses.
+
+       NetBSD curses documents different exit codes which do not correspond to
+       either ncurses or X/Open.

+       This program initializes terminals.
+
+       First,  <STRONG>tset</STRONG>  retrieves  the  current  terminal  mode settings for your
+       terminal.  It does this by successively testing
+
+       <STRONG>o</STRONG>   the standard error,
+
+       <STRONG>o</STRONG>   standard output,
+
+       <STRONG>o</STRONG>   standard input and
+
+       <STRONG>o</STRONG>   ultimately "/dev/tty"
+
+       to obtain terminal settings.  Having  retrieved  these  settings,  <STRONG>tset</STRONG>
+       remembers which file descriptor to use when updating settings.
+
+       Next,  <STRONG>tset</STRONG>  determines  the type of terminal that you are using.  This
+       determination is done as follows, using the first terminal type found.
+
+       1. The <STRONG>terminal</STRONG> argument specified on the command line.
+
+       2. The value of the <STRONG>TERM</STRONG> environmental variable.
+
+       3. (BSD systems only.) The terminal type associated with  the  standard
+       error  output  device  in the <EM>/etc/ttys</EM> file.  (On System-V-like UNIXes
+       and systems using that convention, <STRONG>getty(1)</STRONG> does this  job  by  setting
+       <STRONG>TERM</STRONG> according to the type passed to it by <EM>/etc/inittab</EM>.)
+
+       4. The default terminal type, "unknown".
+
+       If  the  terminal  type  was  not specified on the command-line, the <STRONG>-m</STRONG>
+       option mappings are then applied (see the section <STRONG>TERMINAL</STRONG> <STRONG>TYPE</STRONG> <STRONG>MAPPING</STRONG>
+       for  more  information).   Then,  if  the  terminal  type begins with a
+       question mark ("?"), the user  is  prompted  for  confirmation  of  the
+       terminal  type.   An empty response confirms the type, or, another type
+       can be entered to specify a new type.  Once the terminal type has  been
+       determined, the terminal description for the terminal is retrieved.  If
+       no terminal description is found for the type, the user is prompted for
+       another terminal type.
+
+       Once the terminal description is retrieved,
+
+       <STRONG>o</STRONG>   if  the  "<STRONG>-w</STRONG>"  option  is  enabled,  <STRONG>tset</STRONG> may update the terminal's
+           window size.
+
+           If the window size cannot be obtained from  the  operating  system,
+           but  the  terminal  description  (or  environment,  e.g., <STRONG>LINES</STRONG> and
+           <STRONG>COLUMNS</STRONG> variables specify this), use  this  to  set  the  operating
+           system's notion of the window size.
+
+       <STRONG>o</STRONG>   if  the  "<STRONG>-c</STRONG>"  option is enabled, the backspace, interrupt and line
+           kill characters (among many other things) are set
+
+       <STRONG>o</STRONG>   unless  the  "<STRONG>-I</STRONG>"  option  is  enabled,  the   terminal   and   tab
+           <EM>initialization</EM>  strings  are sent to the standard error output, and
+           <STRONG>tset</STRONG> waits one second (in case a hardware reset was issued).
+
+       <STRONG>o</STRONG>   Finally, if the erase, interrupt  and  line  kill  characters  have
+           changed,  or  are not set to their default values, their values are
+           displayed to the standard error output.
+
+
+</PRE><H3><a name="h3-reset---reinitialization">reset - reinitialization</a></H3><PRE>
+       When invoked as <STRONG>reset</STRONG>, <STRONG>tset</STRONG> sets the terminal modes to "sane" values:
+
+       <STRONG>o</STRONG>   sets cooked and echo modes,
+
+       <STRONG>o</STRONG>   turns off cbreak and raw modes,
+
+       <STRONG>o</STRONG>   turns on newline translation and
+
+       <STRONG>o</STRONG>   resets any unset special characters to their default values
+
+       before doing the terminal initialization described above.  Also, rather
+       than  using  the  terminal <EM>initialization</EM> strings, it uses the terminal
+       <EM>reset</EM> strings.
+
+       The <STRONG>reset</STRONG> command is useful after a program dies leaving a terminal  in
+       an abnormal state:
+
+       <STRONG>o</STRONG>   you may have to type
+
+               <EM>&lt;LF&gt;</EM><STRONG>reset</STRONG><EM>&lt;LF&gt;</EM>
+
+           (the line-feed character is normally control-J) to get the terminal
+           to work, as carriage-return may no  longer  work  in  the  abnormal
+           state.
+
+       <STRONG>o</STRONG>   Also, the terminal will often not echo the command.
+
+
+</PRE><H2><a name="h2-OPTIONS">OPTIONS</a></H2><PRE>
+       The options are as follows:
+
+       <STRONG>-c</STRONG>   Set control characters and modes.
+
+       <STRONG>-e</STRONG> <EM>ch</EM>
+            Set the erase character to <EM>ch</EM>.
+
+       <STRONG>-I</STRONG>   Do  not  send  the  terminal  or tab initialization strings to the
+            terminal.
+
+       <STRONG>-i</STRONG> <EM>ch</EM>
+            Set the interrupt character to <EM>ch</EM>.
+
+       <STRONG>-k</STRONG> <EM>ch</EM>
+            Set the line kill character to <EM>ch</EM>.
+
+       <STRONG>-m</STRONG> <EM>mapping</EM>
+            Specify a mapping from a port type to a terminal.  See the section
+            <STRONG>TERMINAL</STRONG> <STRONG>TYPE</STRONG> <STRONG>MAPPING</STRONG> for more information.
+
+       <STRONG>-Q</STRONG>   Do  not  display any values for the erase, interrupt and line kill
+            characters.   Normally  <STRONG>tset</STRONG>  displays  the  values  for   control
+            characters which differ from the system's default values.
+
+       <STRONG>-q</STRONG>   The  terminal  type  is  displayed to the standard output, and the
+            terminal is not initialized in any way.  The option "-" by  itself
+            is equivalent but archaic.
+
+       <STRONG>-r</STRONG>   Print the terminal type to the standard error output.
+
+       <STRONG>-s</STRONG>   Print the sequence of shell commands to initialize the environment
+            variable <STRONG>TERM</STRONG> to the standard output.  See the section <STRONG>SETTING</STRONG> <STRONG>THE</STRONG>
+            <STRONG>ENVIRONMENT</STRONG> for details.
+
+       <STRONG>-V</STRONG>   reports the version of ncurses which was used in this program, and
+            exits.
+
+       <STRONG>-w</STRONG>   Resize the window to match the  size  deduced  via  <STRONG><A HREF="curs_terminfo.3x.html">setupterm(3x)</A></STRONG>.
+            Normally  this  has  no  effect,  unless  <STRONG>setupterm</STRONG> is not able to
+            detect the window size.
+
+       The arguments for the <STRONG>-e</STRONG>, <STRONG>-i</STRONG>, and <STRONG>-k</STRONG> options may either be  entered  as
+       actual  characters  or by using the "hat" notation, i.e., control-h may
+       be specified as "^H" or "^h".
+
+       If neither <STRONG>-c</STRONG> or <STRONG>-w</STRONG> is given, both options are assumed.
+
+
+</PRE><H2><a name="h2-SETTING-THE-ENVIRONMENT">SETTING THE ENVIRONMENT</a></H2><PRE>
+       It is often desirable to enter the terminal type and information  about
+       the terminal's capabilities into the shell's environment.  This is done
+       using the <STRONG>-s</STRONG> option.
+
+       When the <STRONG>-s</STRONG> option is specified, the commands to enter the  information
+       into  the  shell's  environment are written to the standard output.  If
+       the <STRONG>SHELL</STRONG> environmental variable ends in "csh", the  commands  are  for
+       <STRONG>csh</STRONG>,  otherwise,  they  are  for <STRONG>sh(1)</STRONG>.  Note, the <STRONG>csh</STRONG> commands set and
+       unset the shell variable <STRONG>noglob</STRONG>, leaving it unset.  The following  line
+       in  the  <STRONG>.login</STRONG>  or  <STRONG>.profile</STRONG>  files  will  initialize  the environment
+       correctly:
+
+           eval `tset -s options ... `
+
+
+</PRE><H2><a name="h2-TERMINAL-TYPE-MAPPING">TERMINAL TYPE MAPPING</a></H2><PRE>
+       When the terminal is not hardwired into  the  system  (or  the  current
+       system  information  is  incorrect)  the terminal type derived from the
+       <EM>/etc/ttys</EM> file or the <STRONG>TERM</STRONG> environmental variable  is  often  something
+       generic  like  <STRONG>network</STRONG>,  <STRONG>dialup</STRONG>,  or  <STRONG>unknown</STRONG>.   When <STRONG>tset</STRONG> is used in a
+       startup script it is often desirable to provide information  about  the
+       type of terminal used on such ports.
+
+       The  <STRONG>-m</STRONG>  options  maps  from some set of conditions to a terminal type,
+       that is, to tell <STRONG>tset</STRONG> "If I'm on this port at a particular speed, guess
+       that I'm on that kind of terminal".
+
+       The  argument  to  the  <STRONG>-m</STRONG> option consists of an optional port type, an
+       optional operator, an optional baud  rate  specification,  an  optional
+       colon  (":")  character and a terminal type.  The port type is a string
+       (delimited by  either  the  operator  or  the  colon  character).   The
+       operator  may  be  any combination of "&gt;", "&lt;", "@", and "!"; "&gt;" means
+       greater than, "&lt;" means less than, "@" means equal to and  "!"  inverts
+       the  sense  of the test.  The baud rate is specified as a number and is
+       compared with the speed of the standard error output (which  should  be
+       the control terminal).  The terminal type is a string.
+
+       If  the  terminal  type  is  not  specified on the command line, the <STRONG>-m</STRONG>
+       mappings are applied to the terminal type.  If the port type  and  baud
+       rate  match  the  mapping,  the  terminal type specified in the mapping
+       replaces the current type.  If more than one mapping is specified,  the
+       first applicable mapping is used.
+
+       For  example,  consider  the following mapping: <STRONG>dialup&gt;9600:vt100</STRONG>.  The
+       port type is dialup , the operator is &gt;, the baud rate specification is
+       9600, and the terminal type is vt100.  The result of this mapping is to
+       specify that if the terminal type is  <STRONG>dialup</STRONG>,  and  the  baud  rate  is
+       greater than 9600 baud, a terminal type of <STRONG>vt100</STRONG> will be used.
+
+       If  no  baud  rate  is specified, the terminal type will match any baud
+       rate.  If no port type is specified, the terminal type will  match  any
+       port  type.   For  example,  <STRONG>-m</STRONG>  <STRONG>dialup:vt100</STRONG> <STRONG>-m</STRONG> <STRONG>:?xterm</STRONG> will cause any
+       dialup port, regardless of baud rate, to match the terminal type vt100,
+       and  any non-dialup port type to match the terminal type ?xterm.  Note,
+       because of the leading question mark, the user will  be  queried  on  a
+       default port as to whether they are actually using an xterm terminal.
+
+       No  whitespace  characters  are  permitted  in  the <STRONG>-m</STRONG> option argument.
+       Also, to avoid problems with meta-characters, it is suggested that  the
+       entire <STRONG>-m</STRONG> option argument be placed within single quote characters, and
+       that  <STRONG>csh</STRONG>  users  insert  a  backslash  character  ("\")   before   any
+       exclamation marks ("!").
+
+
+</PRE><H2><a name="h2-HISTORY">HISTORY</a></H2><PRE>
+       A  <STRONG>reset</STRONG> command appeared in 1BSD (March 1978), written by Kurt Shoens.
+       This program set the <EM>erase</EM> and <EM>kill</EM> characters to <STRONG>^H</STRONG> (backspace) and  <STRONG>@</STRONG>
+       respectively.  Mark Horton improved that in 3BSD (October 1979), adding
+       <EM>intr</EM>, <EM>quit</EM>, <EM>start</EM>/<EM>stop</EM> and <EM>eof</EM>  characters  as  well  as  changing  the
+       program  to  avoid  modifying any user settings.  That version of <STRONG>reset</STRONG>
+       did not use the termcap database.
+
+       A separate <STRONG>tset</STRONG> command was provided in 1BSD by Eric Allman, using  the
+       termcap  database.   Allman's comments in the source code indicate that
+       he began work in October 1977, continuing development over the next few
+       years.
+
+       According to comments in the source code, the <STRONG>tset</STRONG> program was modified
+       in September 1980, to use logic copied from the 3BSD  "reset"  when  it
+       was invoked as <STRONG>reset</STRONG>.  This version appeared in 4.1cBSD, late in 1982.
+
+       Other developers (e.g., Keith Bostic and Jim Bloom) continued to modify
+       <STRONG>tset</STRONG> until 4.4BSD was released in 1993.
+
+       The <STRONG>ncurses</STRONG> implementation was lightly adapted from the 4.4BSD  sources
+       for a terminfo environment by Eric S. Raymond &lt;esr@snark.thyrsus.com&gt;.
+
+
+</PRE><H2><a name="h2-COMPATIBILITY">COMPATIBILITY</a></H2><PRE>
+       Neither  IEEE  Std  1003.1/The  Open  Group Base Specifications Issue 7
+       (POSIX.1-2008) nor X/Open Curses Issue 7 documents <STRONG>tset</STRONG> or <STRONG>reset</STRONG>.
+
+       The AT&amp;T <STRONG>tput</STRONG> utility (AIX, HPUX, Solaris) incorporated  the  terminal-
+       mode  manipulation  as well as termcap-based features such as resetting
+       tabstops from <STRONG>tset</STRONG> in BSD (4.1c),  presumably  with  the  intention  of
+       making  <STRONG>tset</STRONG>  obsolete.   However, each of those systems still provides
+       <STRONG>tset</STRONG>.  In fact, the commonly-used <STRONG>reset</STRONG> utility is always an alias  for
+       <STRONG>tset</STRONG>.
+
+       The   <STRONG>tset</STRONG>   utility   provides  for  backward-compatibility  with  BSD
+       environments (under most modern UNIXes, <STRONG>/etc/inittab</STRONG> and  <STRONG>getty(1)</STRONG>  can
+       set  <STRONG>TERM</STRONG>  appropriately  for each dial-up line; this obviates what was
+       <STRONG>tset</STRONG>'s most important use).  This implementation  behaves  like  4.4BSD
+       <STRONG>tset</STRONG>, with a few exceptions specified here.
+
+       A  few  options are different because the <STRONG>TERMCAP</STRONG> variable is no longer
+       supported under terminfo-based <STRONG>ncurses</STRONG>:
+
+       <STRONG>o</STRONG>   The <STRONG>-S</STRONG> option of BSD <STRONG>tset</STRONG> no  longer  works;  it  prints  an  error
+           message to the standard error and dies.
+
+       <STRONG>o</STRONG>   The <STRONG>-s</STRONG> option only sets <STRONG>TERM</STRONG>, not <STRONG>TERMCAP</STRONG>.
+
+       There  was an undocumented 4.4BSD feature that invoking <STRONG>tset</STRONG> via a link
+       named "TSET" (or via  any  other  name  beginning  with  an  upper-case
+       letter) set the terminal to use upper-case only.  This feature has been
+       omitted.
+
+       The <STRONG>-A</STRONG>, <STRONG>-E</STRONG>, <STRONG>-h</STRONG>, <STRONG>-u</STRONG> and <STRONG>-v</STRONG> options were deleted from the <STRONG>tset</STRONG> utility in
+       4.4BSD.   None of them were documented in 4.3BSD and all are of limited
+       utility at best.   The  <STRONG>-a</STRONG>,  <STRONG>-d</STRONG>,  and  <STRONG>-p</STRONG>  options  are  similarly  not
+       documented  or  useful,  but  were  retained  as  they  appear to be in
+       widespread use.  It is strongly recommended that  any  usage  of  these
+       three options be changed to use the <STRONG>-m</STRONG> option instead.  The <STRONG>-a</STRONG>, <STRONG>-d</STRONG>, and
+       <STRONG>-p</STRONG> options are therefore omitted from the usage summary above.
+
+       Very old systems, e.g., 3BSD, used a different  terminal  driver  which
+       was  replaced  in  4BSD in the early 1980s.  To accommodate these older
+       systems, the 4BSD <STRONG>tset</STRONG> provided a <STRONG>-n</STRONG> option to  specify  that  the  new
+       terminal  driver  should be used.  This implementation does not provide
+       that choice.
+
+       It is still permissible to specify the <STRONG>-e</STRONG>, <STRONG>-i</STRONG>, and <STRONG>-k</STRONG>  options  without
+       arguments, although it is strongly recommended that such usage be fixed
+       to explicitly specify the character.
+
+       As of 4.4BSD, executing <STRONG>tset</STRONG> as <STRONG>reset</STRONG> no longer implies the <STRONG>-Q</STRONG>  option.
+       Also, the interaction between the - option and the <EM>terminal</EM> argument in
+       some historic implementations of <STRONG>tset</STRONG> has been removed.
+
+       The <STRONG>-c</STRONG> and  <STRONG>-w</STRONG>  options  are  not  found  in  earlier  implementations.
+       However, a different window size-change feature was provided in 4.4BSD.
+
+       <STRONG>o</STRONG>   In  4.4BSD,  <STRONG>tset</STRONG> uses the window size from the termcap description
+           to set the window size if <STRONG>tset</STRONG> is not able  to  obtain  the  window
+           size from the operating system.
+
+       <STRONG>o</STRONG>   In ncurses, <STRONG>tset</STRONG> obtains the window size using <STRONG>setupterm</STRONG>, which may
+           be from the operating system, the  <STRONG>LINES</STRONG>  and  <STRONG>COLUMNS</STRONG>  environment
+           variables or the terminal description.
+
+       Obtaining  the  window  size from the terminal description is common to
+       both implementations, but considered obsolescent.  Its  only  practical
+       use is for hardware terminals.  Generally speaking, a window size would
+       be unset only if there were some problem obtaining the value  from  the
+       operating  system  (and  <STRONG>setupterm</STRONG> would still fail).  For that reason,
+       the <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> environment variables may be useful  for  working
+       around  window-size  problems.   Those  have  the  drawback that if the
+       window is resized, those variables must be recomputed  and  reassigned.
+       To do this more easily, use the <STRONG>resize(1)</STRONG> program.
+
+
+</PRE><H2><a name="h2-ENVIRONMENT">ENVIRONMENT</a></H2><PRE>
+       The <STRONG>tset</STRONG> command uses these environment variables:
+
+       SHELL
+            tells  <STRONG>tset</STRONG>  whether  to  initialize  <STRONG>TERM</STRONG>  using  <STRONG>sh(1)</STRONG> or <STRONG>csh(1)</STRONG>
+            syntax.
+
+       TERM Denotes your terminal  type.   Each  terminal  type  is  distinct,
+            though many are similar.
+
+       TERMCAP
+            may  denote  the  location of a termcap database.  If it is not an
+            absolute pathname, e.g., begins  with  a  "/",  <STRONG>tset</STRONG>  removes  the
+            variable  from  the  environment  before  looking for the terminal

+       Before  ncurses  5.0,  terminfo  databases  used  a <EM>fixed</EM> <EM>repertoire</EM> of
+       terminal capabilities designed for the SVr2 terminal database in  1984,
+       and  extended  in  stages  through SVr4 (1989), and standardized in the
+       Single Unix Specification beginning in 1995.
+
+       Most of the <EM>extensions</EM> in this fixed repertoire were additions  to  the
+       tables of boolean, numeric and string capabilities.  Rather than change
+       the meaning of an existing capability,  a  new  name  was  added.   The
+       terminfo  database  uses  a  binary  format;  binary  compatibility was
+       ensured by using a header which gave the number of items in the  tables
+       for each type of capability.  The standardization was incomplete:
+
+       <STRONG>o</STRONG>   The  <EM>binary</EM>  <EM>format</EM>  itself  is  not described in the X/Open Curses
+           documentation.  Only the <EM>source</EM> <EM>format</EM> is described.
+
+           Library developers rely upon the SVr4 documentation,  and  reverse-
+           engineering the compiled terminfo files to match the binary format.
+
+       <STRONG>o</STRONG>   Lacking a standard for the binary format, most implementations copy
+           the SVr2 binary format, which uses 16-bit signed integers,  and  is
+           limited to 4096-byte entries.
+
+           The  format  cannot  represent very large numeric capabilities, nor
+           can it represent large numbers of special keyboard definitions.
+
+       <STRONG>o</STRONG>   The tables of capability names differ between implementations.
+
+           Although they <EM>may</EM> provide all of the standard capability names, the
+           position  in the tables differs because some features were added as
+           needed, while others were added  (out  of  order)  to  comply  with
+           X/Open Curses.
+
+           While  ncurses' repertoire of predefined capabilities is closest to
+           Solaris, Solaris's terminfo database has a few differences from the
+           list  published  by  X/Open  Curses.   For  example, ncurses can be
+           configured with tables which match the terminal databases for  AIX,
+           HP-UX or OSF/1, rather than the default Solaris-like configuration.
+
+       <STRONG>o</STRONG>   In  SVr4  curses  and  ncurses, the terminal database is defined at
+           compile-time using a text file which lists the  different  terminal
+           capabilities.
+
+           In  principle,  the  text-file  can  be  extended,  but  doing this
+           requires recompiling and reinstalling the library.   The  text-file
+           used  in  ncurses  for  terminal  capabilities includes details for
+           various systems past the documented X/Open  Curses  features.   For
+           example, ncurses supports these capabilities in each configuration:
+
+               memory_lock
+                    (meml) lock memory above cursor
+
+               memory_unlock
+                    (memu) unlock memory
+
+               box_chars_1
+                    (box1) box characters primary set
+
+           The memory lock/unlock capabilities were included because they were
+           used in the X11R6 terminal  description  for  <STRONG>xterm(1)</STRONG>.   The  <EM>box1</EM>
+           capability  is  used  in  tic  to  help  with terminal descriptions
+           written for AIX.
+
+       During the 1990s, some users were reluctant to use terminfo in spite of
+       its performance advantages over termcap:
+
+       <STRONG>o</STRONG>   The  fixed  repertoire  prevented  users  from  adding features for
+           unanticipated terminal improvements  (or  required  them  to  reuse
+           existing capabilities as a workaround).
+
+       <STRONG>o</STRONG>   The  limitation  to  16-bit  signed  integers  was  also mentioned.
+           Because termcap stores everything as a string, it  could  represent
+           larger numbers.
+
+       Although  termcap's  extensibility  was  rarely  used (it was never the
+       <EM>speaker</EM> who had actually used the feature), the criticism had a  point.
+       ncurses   5.0  provided  a  way  to  detect  nonstandard  capabilities,
+       determine their type and optionally store and retrieve them  in  a  way
+       which did not interfere with other applications.  These are referred to
+       as <EM>user-defined</EM> <EM>capabilities</EM> because no modifications to the  toolset's
+       predefined capability names are needed.
+
+       The  ncurses  utilities <STRONG>tic</STRONG> and <STRONG>infocmp</STRONG> have a command-line option "-x"
+       to  control  whether  the  nonstandard  capabilities  are   stored   or
+       retrieved.   A  library function <STRONG>use_extended_names</STRONG> is provided for the
+       same purpose.
+
+       When compiling a terminal database, if "-x" is set, <STRONG>tic</STRONG>  will  store  a
+       user-defined  capability  if  the  capability  name  is  not one of the
+       predefined names.
+
+       Because ncurses provides  a  termcap  library  interface,  these  user-
+       defined capabilities may be visible to termcap applications:
+
+       <STRONG>o</STRONG>   The   termcap  interface  (like  all  implementations  of  termcap)
+           requires that the capability names are 2-characters.
+
+           When  the  capability  is  simple  enough  for  use  in  a  termcap
+           application, it is provided as a 2-character name.
+
+       <STRONG>o</STRONG>   There  are  other user-defined capabilities which refer to features
+           not usable in termcap, e.g., parameterized strings  that  use  more
+           than two parameters or use more than the trivial expression support
+           provided by termcap.  For these, the terminfo database should  have
+           only capability names with 3 or more characters.
+
+       <STRONG>o</STRONG>   Some terminals can send distinct strings for special keys (cursor-,
+           keypad-  or  function-keys)  depending  on  modifier  keys  (shift,
+           control,  etc.).   While  terminfo  and  termcap  have  a set of 60
+           predefined function-key names, to which a series  of  keys  can  be
+           assigned,   that  is  insufficient  for  more  than  a  dozen  keys
+           multiplied by more than a couple  of  modifier  combinations.   The
+           ncurses  database  uses  a  convention based on <STRONG>xterm(1)</STRONG> to provide
+           extended special-key names.
+
+           Fitting that into termcap's limitation of 2-character  names  would
+           be   pointless.   These  extended  keys  are  available  only  with
+           terminfo.
+

+       The ncurses library uses the user-definable  capabilities.   While  the
+       terminfo  database  may  have  other extensions, ncurses makes explicit
+       checks for these:
+
+          AX <EM>boolean</EM>, asserts that the terminal interprets SGR 39 and  SGR  49
+             by  resetting  the foreground and background color, respectively,
+             to the default.
+
+             This is a feature recognized by the <STRONG>screen</STRONG> program as well.
+
+          E3 <EM>string</EM>, tells how to  clear  the  terminal's  scrollback  buffer.
+             When present, the <STRONG><A HREF="clear.1.html">clear(1)</A></STRONG> program sends this before clearing the
+             terminal.
+
+             The command "<STRONG>tput</STRONG> <STRONG>clear</STRONG>" does the same thing.
+
+          NQ used to suppress a consistency  check  in  tic  for  the  ncurses
+             capabilities  in  user6  through  user9 (u6, u7, u8 and u9) which
+             tell how to query the terminal's cursor position and  its  device
+             attributes.
+
+          RGB
+             <EM>boolean</EM>,   <EM>number</EM>   <STRONG>or</STRONG>   <EM>string</EM>,   used   to   assert   that  the
+             <STRONG>set_a_foreground</STRONG> and <STRONG>set_a_background</STRONG> capabilities correspond  to
+             <EM>direct</EM>  <EM>colors</EM>,  using  an RGB (red/green/blue) convention.  This
+             capability  allows   the   <STRONG>color_content</STRONG>   function   to   return
+             appropriate   values   without   requiring   the  application  to
+             initialize colors using <STRONG>init_color</STRONG>.
+
+             The capability type determines the values which ncurses sees:
+
+             <EM>boolean</EM>
+                implies that the number of bits for red, green  and  blue  are
+                the  same.   Using  the maximum number of colors, ncurses adds
+                two, divides that sum by three, and assigns the result to red,
+                green and blue in that order.
+
+                If the number of bits needed for the number of colors is not a
+                multiple of three, the blue (and  green)  components  lose  in
+                comparison to red.
+
+             <EM>number</EM>
+                tells  ncurses  what result to add to red, green and blue.  If
+                ncurses runs out of bits, blue (and green) lose just as in the
+                <EM>boolean</EM> case.
+
+             <EM>string</EM>
+                explicitly  list  the  number  of bits used for red, green and
+                blue components as a slash-separated list of decimal integers.
+
+             Because there are several  RGB  encodings  in  use,  applications
+             which  make  assumptions  about  the number of bits per color are
+             unlikely to work reliably.  As a trivial case, for  example,  one
+             could  define  <STRONG>RGB#1</STRONG> to represent the standard eight ANSI colors,
+             i.e., one bit per color.
+
+          U8 <EM>number</EM>, asserts that ncurses must use Unicode  values  for  line-
+             drawing  characters,  and  that  it  should  ignore the alternate
+             character set capabilities when the locale uses  UTF-8  encoding.
+             For  more  information, see the discussion of <STRONG>NCURSES_NO_UTF8_ACS</STRONG>
+             in <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>.
+
+             Set this capability to a nonzero value to enable it.
+
+          XM <EM>string</EM>, override ncurses's built-in string which enables/disables
+             <STRONG>xterm(1)</STRONG> mouse mode.
+
+             ncurses  sends a character sequence to the terminal to initialize
+             mouse mode, and when the user clicks the  mouse  buttons  or  (in
+             certain  modes) moves the mouse, handles the characters sent back
+             by the terminal to tell it what was done with the mouse.
+
+             The mouse protocol  is  enabled  when  the  <EM>mask</EM>  passed  in  the
+             <STRONG>mousemask</STRONG>  function  is nonzero.  By default, ncurses handles the
+             responses for the X11 xterm mouse protocol.  It also knows  about
+             the  <EM>SGR</EM>  <EM>1006</EM>  xterm mouse protocol, but must to be told to look
+             for this specifically.  It will not be able to guess  which  mode
+             is  used,  because  the  responses  are  enough  alike  that only
+             confusion would result.
+
+             The <STRONG>XM</STRONG> capability has a single parameter.  If nonzero, the  mouse
+             protocol  should  be enabled.  If zero, the mouse protocol should
+             be disabled.  ncurses inspects this capability if it is  present,
+             to  see whether the 1006 protocol is used.  If so, it expects the
+             responses to use the <EM>SGR</EM> <EM>1006</EM> xterm mouse protocol.
+
+             The xterm mouse protocol is used  by  other  terminal  emulators.
+             The  terminal database uses building-blocks for the various xterm
+             mouse  protocols  which  can  be  used  in  customized   terminal
+             descriptions.
+
+             The terminal database building blocks for this mouse feature also
+             have  an  experimental  capability  <EM>xm</EM>.   The   "xm"   capability
+             describes  the mouse response.  Currently there is no interpreter
+             which would use  this  information  to  make  the  mouse  support
+             completely data-driven.
+
+             <EM>xm</EM> shows the format of the mouse responses.  In this experimental
+             capability, the parameters are
+
+               <EM>p1</EM>   y-ordinate
+
+               <EM>p2</EM>   x-ordinate
+
+               <EM>p3</EM>   button
+
+               <EM>p4</EM>   state, e.g., pressed or released
+

+
+               <EM>p8</EM>   x-ordinate ending region
+
+             Here are  examples  from  the  terminal  database  for  the  most

+       Several  terminals  provide  the  ability  to send distinct strings for
+       combinations of modified special keys.  There is no standard  for  what
+       those keys can send.
+
+       Since  1999,  <STRONG>xterm(1)</STRONG>  has  supported  <EM>shift</EM>,  <EM>control</EM>,  <EM>alt</EM>, and <EM>meta</EM>
+       modifiers which produce distinct special-key strings.   In  a  terminal
+       description,  ncurses  has  no special knowledge of the modifiers used.
+       Applications can use the <EM>naming</EM> <EM>convention</EM>  established  for  <STRONG>xterm</STRONG>  to
+       find these special keys in the terminal description.
+
+       Starting  with  the curses convention that <EM>key</EM> <EM>names</EM> begin with "k" and
+       that shifted special keys are  an  uppercase  name,  ncurses'  terminal
+       database defines these names to which a suffix is added:
+
+            <STRONG>Name</STRONG>   <STRONG>Description</STRONG>
+            ---------------------------------------------------------------
+            kDC    special form of kdch1 (delete character)
+            kDN    special form of kcud1 (cursor down)
+            kEND   special form of kend (End)
+            kHOM   special form of khome (Home)
+            kLFT   special form of kcub1 (cursor-left or cursor-back)
+            kNXT   special form of knext (Next, or Page-Down)
+            kPRV   special form of kprev (Prev, or Page-Up)
+            kRIT   special form of kcuf1 (cursor-right, or cursor-forward)
+            kUP    special form of kcuu1 (cursor-up)
+
+       These are the suffixes used to denote the modifiers:
+
+            <STRONG>Value</STRONG>   <STRONG>Description</STRONG>
+            ----------------------------------
+            2       Shift

+
+       None  of these are predefined; terminal descriptions can refer to <EM>names</EM>
+       which ncurses will allocate at runtime to <EM>key-codes</EM>.  To use these keys
+       in an ncurses program, an application could do this:
+

+       This is an extension to the curses library.  It reallocates storage for
+       an <STRONG>ncurses</STRONG> window to adjust its dimensions to the specified values.  If
+       either  dimension  is larger than the current values, the window's data
+       is filled with blanks that have the current  background  rendition  (as

+       The  function  returns  the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.

+       The  only  restriction placed on the dimensions is that they be greater

+  <h2><a name="introduction" id="introduction">Introduction</a></h2>
+
+  <p>This document is an introduction to programming with
+  <code>curses</code>. It is not an exhaustive reference for the
+  curses Application Programming Interface (API); that role is
+  filled by the <code>curses</code> manual pages. Rather, it is
+  intended to help C programmers ease into using the package.</p>
+
+  <p>This document is aimed at C applications programmers not yet
+  specifically familiar with ncurses. If you are already an
+  experienced <code>curses</code> programmer, you should
+  nevertheless read the sections on <a href="#mouse">Mouse
+  Interfacing</a>, <a href="#debugging">Debugging</a>, <a href=
+  "#compat">Compatibility with Older Versions</a>, and <a href=
+  "#hints">Hints, Tips, and Tricks</a>. These will bring you up to
+  speed on the special features and quirks of the
+  <code>ncurses</code> implementation. If you are not so
+  experienced, keep reading.</p>
+
+  <p>The <code>curses</code> package is a subroutine library for
+  terminal-independent screen-painting and input-event handling
+  which presents a high level screen model to the programmer,
+  hiding differences between terminal types and doing automatic
+  optimization of output to change one screen full of text into
+  another. <code>Curses</code> uses terminfo, which is a database
+  format that can describe the capabilities of thousands of
+  different terminals.</p>
+
+  <p>The <code>curses</code> API may seem something of an archaism
+  on UNIX desktops increasingly dominated by X, Motif, and Tcl/Tk.
+  Nevertheless, UNIX still supports tty lines and X supports
+  <em>xterm(1)</em>; the <code>curses</code> API has the advantage
+  of (a) back-portability to character-cell terminals, and (b)
+  simplicity. For an application that does not require bit-mapped
+  graphics and multiple fonts, an interface implementation using
+  <code>curses</code> will typically be a great deal simpler and
+  less expensive than one using an X toolkit.</p>
+
+  <h3><a name="history" id="history">A Brief History of Curses</a></h3>
+
+  <p>Historically, the first ancestor of <code>curses</code> was
+  the routines written to provide screen-handling for the
+  <code>vi</code> editor; these used the <code>termcap</code>
+  database facility (both released in 3BSD) for describing terminal
+  capabilities. These routines were abstracted into a documented
+  library and first released with the early BSD UNIX versions. All
+  of this work was done by students at the University of California
+  (Berkeley campus). The curses library was first published in
+  4.0BSD, a year after 3BSD (i.e., late 1980).</p>
+
+  <p>After graduation, one of those students went to work at
+  AT&amp;T Bell Labs, and made an improved <code>termcap</code>
+  library called <code>terminfo</code> (i.e.,
+  &ldquo;libterm&rdquo;), and adapted the curses library to use
+  this. That was subsequently released in System V Release 2 (early
+  1984). Thereafter, other developers added to the curses and
+  terminfo libraries. For instance, a student at Cornell University
+  wrote an improved terminfo library as well as a tool
+  (<code>tic</code>) to compile the terminal descriptions. As a
+  general rule, AT&amp;T did not identify the developers in the
+  source-code or documentation; the <code>tic</code> and
+  <code>infocmp</code> programs are the exceptions.</p>
+
+  <p>System V Release 3 (System III UNIX) from Bell Labs featured a
+  rewritten and much-improved <code>curses</code> library, along
+  with the <code>tic</code> program (late 1986).</p>
+
+  <p>To recap, terminfo is based on Berkeley's termcap database,
+  but contains a number of improvements and extensions.
+  Parameterized capabilities strings were introduced, making it
+  possible to describe multiple video attributes, and colors and to
+  handle far more unusual terminals than possible with termcap. In
+  the later AT&amp;T System V releases, <code>curses</code> evolved
+  to use more facilities and offer more capabilities, going far
+  beyond BSD curses in power and flexibility.</p>
+
+  <h3><a name="scope" id="scope">Scope of This Document</a></h3>
+
+  <p>This document describes <code>ncurses</code>, a free
+  implementation of the System V <code>curses</code> API with some
+  clearly marked extensions. It includes the following System V
+  curses features:</p>
+
+  <ul>
+    <li>Support for multiple screen highlights (BSD curses could
+    only handle one &ldquo;standout&rdquo; highlight, usually
+    reverse-video).</li>
+
+    <li>Support for line- and box-drawing using forms
+    characters.</li>
+
+    <li>Recognition of function keys on input.</li>
+
+    <li>Color support.</li>
+
+    <li>Support for pads (windows of larger than screen size on
+    which the screen or a subwindow defines a viewport).</li>
+  </ul>
+
+  <p>Also, this package makes use of the insert and delete line and
+  character features of terminals so equipped, and determines how
+  to optimally use these features with no help from the programmer.
+  It allows arbitrary combinations of video attributes to be
+  displayed, even on terminals that leave &ldquo;magic
+  cookies&rdquo; on the screen to mark changes in attributes.</p>
+
+  <p>The <code>ncurses</code> package can also capture and use
+  event reports from a mouse in some environments (notably, xterm
+  under the X window system). This document includes tips for using
+  the mouse.</p>
+
+  <p>The <code>ncurses</code> package was originated by Pavel
+  Curtis. The original maintainer of this package is <a href=
+  "mailto:zmbenhal@netcom.com">Zeyd Ben-Halim</a>
+  &lt;zmbenhal@netcom.com&gt;. <a href=
+  "mailto:esr@snark.thyrsus.com">Eric S. Raymond</a>
+  &lt;esr@snark.thyrsus.com&gt; wrote many of the new features in
+  versions after 1.8.1 and wrote most of this introduction.
+  J&uuml;rgen Pfeifer wrote all of the menu and forms code as well
+  as the <a href="http://www.adahome.com">Ada95</a> binding.
+  Ongoing work is being done by <a href=
+  "mailto:dickey@invisible-island.net">Thomas Dickey</a>
+  (maintainer). Contact the current maintainers at <a href=
+  "mailto:bug-ncurses@gnu.org">bug-ncurses@gnu.org</a>.</p>
+
+  <p>This document also describes the <a href="#panels">panels</a>
+  extension library, similarly modeled on the SVr4 panels facility.
+  This library allows you to associate backing store with each of a
+  stack or deck of overlapping windows, and provides operations for
+  moving windows around in the stack that change their visibility
+  in the natural way (handling window overlaps).</p>
+
+  <p>Finally, this document describes in detail the <a href=
+  "#menu">menus</a> and <a href="#form">forms</a> extension
+  libraries, also cloned from System V, which support easy
+  construction and sequences of menus and fill-in forms.</p>
+
+  <h3><a name="terminology" id="terminology">Terminology</a></h3>
+
+  <p>In this document, the following terminology is used with
+  reasonable consistency:</p>
+
+  <dl>
+    <dt>window</dt>
+
+    <dd>A data structure describing a sub-rectangle of the screen
+    (possibly the entire screen). You can write to a window as
+    though it were a miniature screen, scrolling independently of
+    other windows on the physical screen.</dd>
+
+    <dt>screens</dt>
+
+    <dd>A subset of windows which are as large as the terminal
+    screen, i.e., they start at the upper left hand corner and
+    encompass the lower right hand corner. One of these,
+    <code>stdscr</code>, is automatically provided for the
+    programmer.</dd>
+
+    <dt>terminal screen</dt>
+
+    <dd>The package's idea of what the terminal display currently
+    looks like, i.e., what the user sees now. This is a special
+    screen.</dd>
+  </dl>
+

+
+  <h3><a name="overview" id="overview">An Overview of Curses</a></h3>
+
+  <h4><a name="compiling" id="compiling">Compiling Programs using
+  Curses</a></h4>
+
+  <p>In order to use the library, it is necessary to have certain
+  types and variables defined. Therefore, the programmer must have
+  a line:</p>
+
+  <pre class="code-block">
+          #include &lt;curses.h&gt;
+</pre>
+  <p>at the top of the program source. The screen package uses the
+  Standard I/O library, so <code>&lt;curses.h&gt;</code> includes
+  <code>&lt;stdio.h&gt;</code>. <code>&lt;curses.h&gt;</code> also
+  includes <code>&lt;termios.h&gt;</code>,
+  <code>&lt;termio.h&gt;</code>, or <code>&lt;sgtty.h&gt;</code>
+  depending on your system. It is redundant (but harmless) for the
+  programmer to do these includes, too. In linking with
+  <code>curses</code> you need to have <code>-lncurses</code> in
+  your LDFLAGS or on the command line. There is no need for any
+  other libraries.</p>
+
+  <h4><a name="updating" id="updating">Updating the Screen</a></h4>
+
+  <p>In order to update the screen optimally, it is necessary for
+  the routines to know what the screen currently looks like and
+  what the programmer wants it to look like next. For this purpose,
+  a data type (structure) named WINDOW is defined which describes a
+  window image to the routines, including its starting position on
+  the screen (the (y, x) coordinates of the upper left hand corner)
+  and its size. One of these (called <code>curscr</code>, for
+  current screen) is a screen image of what the terminal currently
+  looks like. Another screen (called <code>stdscr</code>, for
+  standard screen) is provided by default to make changes on.</p>
+
+  <p>A window is a purely internal representation. It is used to
+  build and store a potential image of a portion of the terminal.
+  It does not bear any necessary relation to what is really on the
+  terminal screen; it is more like a scratchpad or write
+  buffer.</p>
+
+  <p>To make the section of physical screen corresponding to a
+  window reflect the contents of the window structure, the routine
+  <code>refresh()</code> (or <code>wrefresh()</code> if the window
+  is not <code>stdscr</code>) is called.</p>
+
+  <p>A given physical screen section may be within the scope of any
+  number of overlapping windows. Also, changes can be made to
+  windows in any order, without regard to motion efficiency. Then,
+  at will, the programmer can effectively say &ldquo;make it look
+  like this,&rdquo; and let the package implementation determine
+  the most efficient way to repaint the screen.</p>
+
+  <h4><a name="stdscr" id="stdscr">Standard Windows and Function
+  Naming Conventions</a></h4>
+
+  <p>As hinted above, the routines can use several windows, but two
+  are automatically given: <code>curscr</code>, which knows what
+  the terminal looks like, and <code>stdscr</code>, which is what
+  the programmer wants the terminal to look like next. The user
+  should never actually access <code>curscr</code> directly.
+  Changes should be made to through the API, and then the routine
+  <code>refresh()</code> (or <code>wrefresh()</code>) called.</p>
+
+  <p>Many functions are defined to use <code>stdscr</code> as a
+  default screen. For example, to add a character to
+  <code>stdscr</code>, one calls <code>addch()</code> with the
+  desired character as argument. To write to a different window.
+  use the routine <code>waddch()</code> (for
+  <strong>w</strong>indow-specific addch()) is provided. This
+  convention of prepending function names with a &ldquo;w&rdquo;
+  when they are to be applied to specific windows is consistent.
+  The only routines which do not follow it are those for which a
+  window must always be specified.</p>
+
+  <p>In order to move the current (y, x) coordinates from one point
+  to another, the routines <code>move()</code> and
+  <code>wmove()</code> are provided. However, it is often desirable
+  to first move and then perform some I/O operation. In order to
+  avoid clumsiness, most I/O routines can be preceded by the prefix
+  &ldquo;mv&rdquo; and the desired (y, x) coordinates prepended to
+  the arguments to the function. For example, the calls</p>
+
+  <pre class="code-block">
+          move(y, x);
+          addch(ch);
+</pre>
+  <p>can be replaced by</p>
+
+  <pre class="code-block">
+          mvaddch(y, x, ch);
+</pre>
+  <p>and</p>
+
+  <pre class="code-block">
+          wmove(win, y, x);
+          waddch(win, ch);
+</pre>
+  <p>can be replaced by</p>
+
+  <pre class="code-block">
+          mvwaddch(win, y, x, ch);
+</pre>
+  <p>Note that the window description pointer (win) comes before
+  the added (y, x) coordinates. If a function requires a window
+  pointer, it is always the first parameter passed.</p>
+
+  <h4><a name="variables" id="variables">Variables</a></h4>
+
+  <p>The <code>curses</code> library sets some variables describing
+  the terminal capabilities.</p>
+
+  <pre class="code-block">
+      type   name      description
+      ------------------------------------------------------------------
+      int    LINES     number of lines on the terminal
+      int    COLS      number of columns on the terminal
+</pre>
+  <p>The <code>curses.h</code> also introduces some
+  <code>#define</code> constants and types of general
+  usefulness:</p>
+
+  <dl>
+    <dt><code>bool</code>
+    </dt>
+
+    <dd>boolean type, actually a &ldquo;char&rdquo; (e.g.,

+
+  <h3><a name="using" id="using">Using the Library</a></h3>
+
+  <p>Now we describe how to actually use the screen package. In it,

+  <h4><a name="starting" id="starting">Starting up</a></h4>
+
+  <p>In order to use the screen package, the routines must know
+  about terminal characteristics, and the space for
+  <code>curscr</code> and <code>stdscr</code> must be allocated.
+  These function <code>initscr()</code> does both these things.
+  Since it must allocate space for the windows, it can overflow
+  memory when attempting to do so. On the rare occasions this
+  happens, <code>initscr()</code> will terminate the program with
+  an error message. <code>initscr()</code> must always be called
+  before any of the routines which affect windows are used. If it
+  is not, the program will core dump as soon as either
+  <code>curscr</code> or <code>stdscr</code> are referenced.
+  However, it is usually best to wait to call it until after you
+  are sure you will need it, like after checking for startup
+  errors. Terminal status changing routines like <code>nl()</code>
+  and <code>cbreak()</code> should be called after
+  <code>initscr()</code>.</p>
+
+  <p>Once the screen windows have been allocated, you can set them
+  up for your program. If you want to, say, allow a screen to
+  scroll, use <code>scrollok()</code>. If you want the cursor to be
+  left in place after the last change, use <code>leaveok()</code>.
+  If this is not done, <code>refresh()</code> will move the cursor
+  to the window's current (y, x) coordinates after updating it.</p>
+
+  <p>You can create new windows of your own using the functions
+  <code>newwin()</code>, <code>derwin()</code>, and
+  <code>subwin()</code>. The routine <code>delwin()</code> will
+  allow you to get rid of old windows. All the options described
+  above can be applied to any window.</p>
+
+  <h4><a name="output" id="output">Output</a></h4>
+
+  <p>Now that we have set things up, we will want to actually
+  update the terminal. The basic functions used to change what will
+  go on a window are <code>addch()</code> and <code>move()</code>.
+  <code>addch()</code> adds a character at the current (y, x)
+  coordinates. <code>move()</code> changes the current (y, x)
+  coordinates to whatever you want them to be. It returns
+  <code>ERR</code> if you try to move off the window. As mentioned
+  above, you can combine the two into <code>mvaddch()</code> to do
+  both things at once.</p>
+
+  <p>The other output functions, such as <code>addstr()</code> and
+  <code>printw()</code>, all call <code>addch()</code> to add
+  characters to the window.</p>
+
+  <p>After you have put on the window what you want there, when you
+  want the portion of the terminal covered by the window to be made
+  to look like it, you must call <code>refresh()</code>. In order
+  to optimize finding changes, <code>refresh()</code> assumes that
+  any part of the window not changed since the last
+  <code>refresh()</code> of that window has not been changed on the
+  terminal, i.e., that you have not refreshed a portion of the
+  terminal with an overlapping window. If this is not the case, the
+  routine <code>touchwin()</code> is provided to make it look like
+  the entire window has been changed, thus making
+  <code>refresh()</code> check the whole subsection of the terminal
+  for changes.</p>
+
+  <p>If you call <code>wrefresh()</code> with <code>curscr</code>
+  as its argument, it will make the screen look like
+  <code>curscr</code> thinks it looks like. This is useful for
+  implementing a command which would redraw the screen in case it
+  get messed up.</p>
+
+  <h4><a name="input" id="input">Input</a></h4>
+
+  <p>The complementary function to <code>addch()</code> is
+  <code>getch()</code> which, if echo is set, will call
+  <code>addch()</code> to echo the character. Since the screen
+  package needs to know what is on the terminal at all times, if
+  characters are to be echoed, the tty must be in raw or cbreak
+  mode. Since initially the terminal has echoing enabled and is in
+  ordinary &ldquo;cooked&rdquo; mode, one or the other has to
+  changed before calling <code>getch()</code>; otherwise, the
+  program's output will be unpredictable.</p>
+
+  <p>When you need to accept line-oriented input in a window, the
+  functions <code>wgetstr()</code> and friends are available. There
+  is even a <code>wscanw()</code> function that can do
+  <code>scanf()</code>(3)-style multi-field parsing on window
+  input. These pseudo-line-oriented functions turn on echoing while
+  they execute.</p>
+
+  <p>The example code above uses the call <code>keypad(stdscr,
+  TRUE)</code> to enable support for function-key mapping. With
+  this feature, the <code>getch()</code> code watches the input
+  stream for character sequences that correspond to arrow and
+  function keys. These sequences are returned as pseudo-character
+  values. The <code>#define</code> values returned are listed in
+  the <code>curses.h</code> The mapping from sequences to
+  <code>#define</code> values is determined by <code>key_</code>
+  capabilities in the terminal's terminfo entry.</p>
+
+  <h4><a name="formschars" id="formschars">Using Forms
+  Characters</a></h4>
+
+  <p>The <code>addch()</code> function (and some others, including
+  <code>box()</code> and <code>border()</code>) can accept some
+  pseudo-character arguments which are specially defined by
+  <code>ncurses</code>. These are <code>#define</code> values set
+  up in the <code>curses.h</code> header; see there for a complete
+  list (look for the prefix <code>ACS_</code>).</p>
+
+  <p>The most useful of the ACS defines are the forms-drawing
+  characters. You can use these to draw boxes and simple graphs on
+  the screen. If the terminal does not have such characters,
+  <code>curses.h</code> will map them to a recognizable (though
+  ugly) set of ASCII defaults.</p>
+
+  <h4><a name="attributes" id="attributes">Character Attributes and
+  Color</a></h4>
+
+  <p>The <code>ncurses</code> package supports screen highlights
+  including standout, reverse-video, underline, and blink. It also
+  supports color, which is treated as another kind of
+  highlight.</p>
+
+  <p>Highlights are encoded, internally, as high bits of the
+  pseudo-character type (<code>chtype</code>) that
+  <code>curses.h</code> uses to represent the contents of a screen
+  cell. See the <code>curses.h</code> header file for a complete
+  list of highlight mask values (look for the prefix
+  <code>A_</code>).</p>
+
+  <p>There are two ways to make highlights. One is to logical-or
+  the value of the highlights you want into the character argument
+  of an <code>addch()</code> call, or any other output call that
+  takes a <code>chtype</code> argument.</p>
+
+  <p>The other is to set the current-highlight value. This is
+  <em>logical-OR</em>ed with any highlight you specify the first
+  way. You do this with the functions <code>attron()</code>,
+  <code>attroff()</code>, and <code>attrset()</code>; see the
+  manual pages for details. Color is a special kind of highlight.
+  The package actually thinks in terms of color pairs, combinations
+  of foreground and background colors. The sample code above sets
+  up eight color pairs, all of the guaranteed-available colors on
+  black. Note that each color pair is, in effect, given the name of
+  its foreground color. Any other range of eight non-conflicting
+  values could have been used as the first arguments of the
+  <code>init_pair()</code> values.</p>
+
+  <p>Once you have done an <code>init_pair()</code> that creates
+  color-pair N, you can use <code>COLOR_PAIR(N)</code> as a
+  highlight that invokes that particular color combination. Note
+  that <code>COLOR_PAIR(N)</code>, for constant N, is itself a
+  compile-time constant and can be used in initializers.</p>
+
+  <h4><a name="mouse" id="mouse">Mouse Interfacing</a></h4>
+
+  <p>The <code>ncurses</code> library also provides a mouse
+  interface.</p>
+
+  <blockquote>
+    <strong>NOTE:</strong> this facility is specific to
+    <code>ncurses</code>, it is not part of either the XSI Curses
+    standard, nor of System V Release 4, nor BSD curses. System V
+    Release 4 curses contains code with similar interface
+    definitions, however it is not documented. Other than by
+    disassembling the library, we have no way to determine exactly
+    how that mouse code works. Thus, we recommend that you wrap
+    mouse-related code in an #ifdef using the feature macro
+    NCURSES_MOUSE_VERSION so it will not be compiled and linked on
+    non-ncurses systems.
+  </blockquote>
+
+  <p>Presently, mouse event reporting works in the following
+  environments:</p>
+
+  <ul>
+    <li>xterm and similar programs such as rxvt.</li>
+
+    <li>Linux console, when configured with <code>gpm</code>(1),
+    Alessandro Rubini's mouse server.</li>
+
+    <li>FreeBSD sysmouse (console)</li>
+
+    <li>OS/2 EMX</li>
+  </ul>
+
+  <p>The mouse interface is very simple. To activate it, you use
+  the function <code>mousemask()</code>, passing it as first
+  argument a bit-mask that specifies what kinds of events you want
+  your program to be able to see. It will return the bit-mask of
+  events that actually become visible, which may differ from the
+  argument if the mouse device is not capable of reporting some of
+  the event types you specify.</p>
+
+  <p>Once the mouse is active, your application's command loop
+  should watch for a return value of <code>KEY_MOUSE</code> from
+  <code>wgetch()</code>. When you see this, a mouse event report
+  has been queued. To pick it off the queue, use the function
+  <code>getmouse()</code> (you must do this before the next
+  <code>wgetch()</code>, otherwise another mouse event might come
+  in and make the first one inaccessible).</p>
+
+  <p>Each call to <code>getmouse()</code> fills a structure (the
+  address of which you will pass it) with mouse event data. The
+  event data includes zero-origin, screen-relative character-cell
+  coordinates of the mouse pointer. It also includes an event mask.
+  Bits in this mask will be set, corresponding to the event type
+  being reported.</p>
+
+  <p>The mouse structure contains two additional fields which may
+  be significant in the future as ncurses interfaces to new kinds
+  of pointing device. In addition to x and y coordinates, there is
+  a slot for a z coordinate; this might be useful with
+  touch-screens that can return a pressure or duration parameter.
+  There is also a device ID field, which could be used to
+  distinguish between multiple pointing devices.</p>
+
+  <p>The class of visible events may be changed at any time via
+  <code>mousemask()</code>. Events that can be reported include
+  presses, releases, single-, double- and triple-clicks (you can
+  set the maximum button-down time for clicks). If you do not make
+  clicks visible, they will be reported as press-release pairs. In
+  some environments, the event mask may include bits reporting the
+  state of shift, alt, and ctrl keys on the keyboard during the
+  event.</p>
+
+  <p>A function to check whether a mouse event fell within a given
+  window is also supplied. You can use this to see whether a given
+  window should consider a mouse event relevant to it.</p>
+
+  <p>Because mouse event reporting will not be available in all
+  environments, it would be unwise to build <code>ncurses</code>
+  applications that <em>require</em> the use of a mouse. Rather,
+  you should use the mouse as a shortcut for point-and-shoot
+  commands your application would normally accept from the
+  keyboard. Two of the test games in the <code>ncurses</code>
+  distribution (<code>bs</code> and <code>knight</code>) contain
+  code that illustrates how this can be done.</p>
+
+  <p>See the manual page <code>curs_mouse(3X)</code> for full
+  details of the mouse-interface functions.</p>
+
+  <h4><a name="finishing" id="finishing">Finishing Up</a></h4>
+
+  <p>In order to clean up after the <code>ncurses</code> routines,
+  the routine <code>endwin()</code> is provided. It restores tty
+  modes to what they were when <code>initscr()</code> was first
+  called, and moves the cursor down to the lower-left corner. Thus,
+  anytime after the call to initscr, <code>endwin()</code> should
+  be called before exiting.</p>
+

+    will clear the screen. If an error occurs a message is written
+    to standard error and the program exits. Otherwise it returns a
+    pointer to stdscr. A few functions may be called before initscr
+    (<code>slk_init()</code>, <code>filter()</code>,

+    non-visual mode. Calling <code>refresh()</code> or

+    should be saved as a reference to that terminal. (NOTE: a
+    SCREEN variable is not a <em>screen</em> in the sense we are
+    describing in this introduction, but a collection of parameters
+    used to assist in optimizing the display.) The arguments are

+    terminal screen: a physical screen, describing what is actually
+    on the screen, and a virtual screen, describing what the
+    programmer wants to have on the screen. wrefresh works by first
+    copying the named window to the virtual screen
+    (<code>wnoutrefresh()</code>), and then calling the routine to
+    update the screen (<code>doupdate()</code>). If the programmer
+    wishes to output several windows at once, a series of calls to
+    <code>wrefresh</code> will result in alternating calls to
+    <code>wnoutrefresh()</code> and <code>doupdate()</code>,
+    causing several bursts of output to the screen. By calling

+
+    <dd>
+      This routine is called to initialize a terminal's
+      description, without setting up the curses screen structures
+      or changing the tty-driver mode bits. <code>term</code> is
+      the character string representing the name of the terminal
+      being used. <code>filenum</code> is the UNIX file descriptor
+      of the terminal to be used for output. <code>errret</code> is
+      a pointer to an integer, in which a success or failure
+      indication is returned. The values returned can be 1 (all is
+      well), 0 (no such terminal), or -1 (some problem locating the
+      terminfo database).
+      <p>The value of <code>term</code> can be given as NULL, which
+      will cause the value of <code>TERM</code> in the environment
+      to be used. The <code>errret</code> pointer can also be given
+      as NULL, meaning no error code is wanted. If
+      <code>errret</code> is defaulted, and something goes wrong,
+      <code>setupterm()</code> will print an appropriate error

+      restoring <code>cur_term</code>, it is possible for a program
+      to use two or more terminals at once.
+      <code>Setupterm()</code> also stores the names section of the
+      terminal description in the global character array
+      <code>ttytype[]</code>. Subsequent calls to
+      <code>setupterm()</code> will overwrite this array, so you
+      will have to save it yourself if need be.</p>

+    of arguments. The output goes to a file called
+    <code>trace</code> in the current directory.</dd>
+  </dl>
+
+  <p>Trace logs can be difficult to interpret due to the sheer
+  volume of data dumped in them. There is a script called
+  <strong>tracemunch</strong> included with the
+  <code>ncurses</code> distribution that can alleviate this problem
+  somewhat; it compacts long sequences of similar operations into
+  more succinct single-line pseudo-operations. These pseudo-ops can
+  be distinguished by the fact that they are named in capital
+  letters.</p>
+
+  <h3><a name="hints" id="hints">Hints, Tips, and Tricks</a></h3>
+
+  <p>The <code>ncurses</code> manual pages are a complete reference
+  for this library. In the remainder of this document, we discuss
+  various useful methods that may not be obvious from the manual
+  page descriptions.</p>
+
+  <h4><a name="caution" id="caution">Some Notes of Caution</a></h4>
+
+  <p>If you find yourself thinking you need to use
+  <code>noraw()</code> or <code>nocbreak()</code>, think again and
+  move carefully. It is probably better design to use
+  <code>getstr()</code> or one of its relatives to simulate cooked
+  mode. The <code>noraw()</code> and <code>nocbreak()</code>
+  functions try to restore cooked mode, but they may end up
+  clobbering some control bits set before you started your
+  application. Also, they have always been poorly documented, and
+  are likely to hurt your application's usability with other curses
+  libraries.</p>
+
+  <p>Bear in mind that <code>refresh()</code> is a synonym for
+  <code>wrefresh(stdscr)</code>. Do not try to mix use of
+  <code>stdscr</code> with use of windows declared by
+  <code>newwin()</code>; a <code>refresh()</code> call will blow
+  them off the screen. The right way to handle this is to use
+  <code>subwin()</code>, or not touch <code>stdscr</code> at all
+  and tile your screen with declared windows which you then
+  <code>wnoutrefresh()</code> somewhere in your program event loop,
+  with a single <code>doupdate()</code> call to trigger actual
+  repainting.</p>
+
+  <p>You are much less likely to run into problems if you design
+  your screen layouts to use tiled rather than overlapping windows.
+  Historically, curses support for overlapping windows has been
+  weak, fragile, and poorly documented. The <code>ncurses</code>
+  library is not yet an exception to this rule.</p>
+
+  <p>There is a panels library included in the <code>ncurses</code>
+  distribution that does a pretty good job of strengthening the
+  overlapping-windows facilities.</p>
+
+  <p>Try to avoid using the global variables LINES and COLS. Use
+  <code>getmaxyx()</code> on the <code>stdscr</code> context
+  instead. Reason: your code may be ported to run in an environment
+  with window resizes, in which case several screens could be open
+  with different sizes.</p>
+
+  <h4><a name="leaving" id="leaving">Temporarily Leaving NCURSES
+  Mode</a></h4>
+
+  <p>Sometimes you will want to write a program that spends most of
+  its time in screen mode, but occasionally returns to ordinary
+  &ldquo;cooked&rdquo; mode. A common reason for this is to support
+  shell-out. This behavior is simple to arrange in
+  <code>ncurses</code>.</p>
+
+  <p>To leave <code>ncurses</code> mode, call <code>endwin()</code>
+  as you would if you were intending to terminate the program. This
+  will take the screen back to cooked mode; you can do your
+  shell-out. When you want to return to <code>ncurses</code> mode,
+  simply call <code>refresh()</code> or <code>doupdate()</code>.
+  This will repaint the screen.</p>
+
+  <p>There is a boolean function, <code>isendwin()</code>, which
+  code can use to test whether <code>ncurses</code> screen mode is
+  active. It returns <code>TRUE</code> in the interval between an
+  <code>endwin()</code> call and the following
+  <code>refresh()</code>, <code>FALSE</code> otherwise.</p>
+
+  <p>Here is some sample code for shellout:</p>
+
+  <pre class="code-block">
+    addstr("Shelling out...");
+    def_prog_mode();           /* save current tty modes */
+    endwin();                  /* restore original tty modes */
+    system("sh");              /* run shell */
+    addstr("returned.\n");     /* prepare return message */
+    refresh();                 /* restore save modes, repaint screen */
+</pre>
+  <h4><a name="xterm" id="xterm">Using NCURSES under XTERM</a></h4>
+
+  <p>A resize operation in X sends <code>SIGWINCH</code> to the
+  application running under xterm. The easiest way to handle
+  <code>SIGWINCH</code> is to do an <code>endwin</code>, followed
+  by an <code>refresh</code> and a screen repaint you code
+  yourself. The <code>refresh</code> will pick up the new screen
+  size from the xterm's environment.</p>
+
+  <p>That is the standard way, of course (it even works with some
+  vendor's curses implementations). Its drawback is that it clears
+  the screen to reinitialize the display, and does not resize
+  subwindows which must be shrunk. <code>Ncurses</code> provides an
+  extension which works better, the <code>resizeterm</code>
+  function. That function ensures that all windows are limited to
+  the new screen dimensions, and pads <code>stdscr</code> with
+  blanks if the screen is larger.</p>
+
+  <p>The <code>ncurses</code> library provides a SIGWINCH signal
+  handler, which pushes a <code>KEY_RESIZE</code> via the wgetch()
+  calls. When <code>ncurses</code> returns that code, it calls
+  <code>resizeterm</code> to update the size of the standard
+  screen's window, repainting that (filling with blanks or
+  truncating as needed). It also resizes other windows, but its
+  effect may be less satisfactory because it cannot know how you
+  want the screen re-painted. You will usually have to write
+  special-purpose code to handle <code>KEY_RESIZE</code>
+  yourself.</p>
+
+  <h4><a name="screens" id="screens">Handling Multiple Terminal
+  Screens</a></h4>
+
+  <p>The <code>initscr()</code> function actually calls a function
+  named <code>newterm()</code> to do most of its work. If you are
+  writing a program that opens multiple terminals, use
+  <code>newterm()</code> directly.</p>
+
+  <p>For each call, you will have to specify a terminal type and a
+  pair of file pointers; each call will return a screen reference,
+  and <code>stdscr</code> will be set to the last one allocated.
+  You will switch between screens with the <code>set_term</code>
+  call. Note that you will also have to call
+  <code>def_shell_mode</code> and <code>def_prog_mode</code> on
+  each tty yourself.</p>
+
+  <h4><a name="testing" id="testing">Testing for Terminal
+  Capabilities</a></h4>
+
+  <p>Sometimes you may want to write programs that test for the
+  presence of various capabilities before deciding whether to go
+  into <code>ncurses</code> mode. An easy way to do this is to call
+  <code>setupterm()</code>, then use the functions
+  <code>tigetflag()</code>, <code>tigetnum()</code>, and
+  <code>tigetstr()</code> to do your testing.</p>
+
+  <p>A particularly useful case of this often comes up when you
+  want to test whether a given terminal type should be treated as
+  &ldquo;smart&rdquo; (cursor-addressable) or &ldquo;stupid&rdquo;.
+  The right way to test this is to see if the return value of
+  <code>tigetstr("cup")</code> is non-NULL. Alternatively, you can
+  include the <code>term.h</code> file and test the value of the
+  macro <code>cursor_address</code>.</p>
+
+  <h4><a name="tuning" id="tuning">Tuning for Speed</a></h4>
+
+  <p>Use the <code>addchstr()</code> family of functions for fast
+  screen-painting of text when you know the text does not contain
+  any control characters. Try to make attribute changes infrequent
+  on your screens. Do not use the <code>immedok()</code>
+  option!</p>
+
+  <h4><a name="special" id="special">Special Features of
+  NCURSES</a></h4>
+
+  <p>The <code>wresize()</code> function allows you to resize a
+  window in place. The associated <code>resizeterm()</code>
+  function simplifies the construction of <a href=
+  "#xterm">SIGWINCH</a> handlers, for resizing all windows.</p>
+
+  <p>The <code>define_key()</code> function allows you to define at
+  runtime function-key control sequences which are not in the
+  terminal description. The <code>keyok()</code> function allows
+  you to temporarily enable or disable interpretation of any
+  function-key control sequence.</p>
+
+  <p>The <code>use_default_colors()</code> function allows you to
+  construct applications which can use the terminal's default
+  foreground and background colors as an additional "default"
+  color. Several terminal emulators support this feature, which is
+  based on ISO 6429.</p>
+
+  <p>Ncurses supports up 16 colors, unlike SVr4 curses which
+  defines only 8. While most terminals which provide color allow
+  only 8 colors, about a quarter (including XFree86 xterm) support
+  16 colors.</p>
+
+  <h3><a name="compat" id="compat">Compatibility with Older
+  Versions</a></h3>
+
+  <p>Despite our best efforts, there are some differences between
+  <code>ncurses</code> and the (undocumented!) behavior of older
+  curses implementations. These arise from ambiguities or omissions
+  in the documentation of the API.</p>
+
+  <h4><a name="refbug" id="refbug">Refresh of Overlapping
+  Windows</a></h4>
+
+  <p>If you define two windows A and B that overlap, and then
+  alternately scribble on and refresh them, the changes made to the
+  overlapping region under historic <code>curses</code> versions
+  were often not documented precisely.</p>
+
+  <p>To understand why this is a problem, remember that screen
+  updates are calculated between two representations of the
+  <em>entire</em> display. The documentation says that when you
+  refresh a window, it is first copied to the virtual screen, and
+  then changes are calculated to update the physical screen (and
+  applied to the terminal). But "copied to" is not very specific,
+  and subtle differences in how copying works can produce different
+  behaviors in the case where two overlapping windows are each
+  being refreshed at unpredictable intervals.</p>
+
+  <p>What happens to the overlapping region depends on what
+  <code>wnoutrefresh()</code> does with its argument -- what
+  portions of the argument window it copies to the virtual screen.
+  Some implementations do "change copy", copying down only
+  locations in the window that have changed (or been marked changed
+  with <code>wtouchln()</code> and friends). Some implementations
+  do "entire copy", copying <em>all</em> window locations to the
+  virtual screen whether or not they have changed.</p>
+
+  <p>The <code>ncurses</code> library itself has not always been
+  consistent on this score. Due to a bug, versions 1.8.7 to 1.9.8a
+  did entire copy. Versions 1.8.6 and older, and versions 1.9.9 and
+  newer, do change copy.</p>
+
+  <p>For most commercial curses implementations, it is not
+  documented and not known for sure (at least not to the
+  <code>ncurses</code> maintainers) whether they do change copy or
+  entire copy. We know that System V release 3 curses has logic in
+  it that looks like an attempt to do change copy, but the
+  surrounding logic and data representations are sufficiently
+  complex, and our knowledge sufficiently indirect, that it is hard
+  to know whether this is reliable. It is not clear what the SVr4
+  documentation and XSI standard intend. The XSI Curses standard
+  barely mentions wnoutrefresh(); the SVr4 documents seem to be
+  describing entire-copy, but it is possible with some effort and
+  straining to read them the other way.</p>
+
+  <p>It might therefore be unwise to rely on either behavior in
+  programs that might have to be linked with other curses
+  implementations. Instead, you can do an explicit
+  <code>touchwin()</code> before the <code>wnoutrefresh()</code>
+  call to guarantee an entire-contents copy anywhere.</p>
+
+  <p>The really clean way to handle this is to use the panels
+  library. If, when you want a screen update, you do
+  <code>update_panels()</code>, it will do all the necessary
+  <code>wnoutrefresh()</code> calls for whatever panel stacking
+  order you have defined. Then you can do one
+  <code>doupdate()</code> and there will be a <em>single</em> burst
+  of physical I/O that will do all your updates.</p>
+
+  <h4><a name="backbug" id="backbug">Background Erase</a></h4>
+
+  <p>If you have been using a very old versions of
+  <code>ncurses</code> (1.8.7 or older) you may be surprised by the
+  behavior of the erase functions. In older versions, erased areas
+  of a window were filled with a blank modified by the window's
+  current attribute (as set by <strong>wattrset()</strong>,
+  <strong>wattron()</strong>, <strong>wattroff()</strong> and
+  friends).</p>
+
+  <p>In newer versions, this is not so. Instead, the attribute of
+  erased blanks is normal unless and until it is modified by the
+  functions <code>bkgdset()</code> or <code>wbkgdset()</code>.</p>
+
+  <p>This change in behavior conforms <code>ncurses</code> to
+  System V Release 4 and the XSI Curses standard.</p>
+
+  <h3><a name="xsifuncs" id="xsifuncs">XSI Curses Conformance</a></h3>
+
+  <p>The <code>ncurses</code> library is intended to be base-level
+  conformant with the XSI Curses standard from X/Open. Many
+  extended-level features (in fact, almost all features not
+  directly concerned with wide characters and internationalization)
+  are also supported.</p>
+
+  <p>One effect of XSI conformance is the change in behavior
+  described under <a href="#backbug">"Background Erase --
+  Compatibility with Old Versions"</a>.</p>
+
+  <p>Also, <code>ncurses</code> meets the XSI requirement that
+  every macro entry point have a corresponding function which may
+  be linked (and will be prototype-checked) if the macro definition
+  is disabled with <code>#undef</code>.</p>
+
+  <h2><a name="panels" id="panels">The Panels Library</a></h2>
+
+  <p>The <code>ncurses</code> library by itself provides good
+  support for screen displays in which the windows are tiled
+  (non-overlapping). In the more general case that windows may
+  overlap, you have to use a series of <code>wnoutrefresh()</code>
+  calls followed by a <code>doupdate()</code>, and be careful about
+  the order you do the window refreshes in. It has to be
+  bottom-upwards, otherwise parts of windows that should be
+  obscured will show through.</p>
+
+  <p>When your interface design is such that windows may dive
+  deeper into the visibility stack or pop to the top at runtime,
+  the resulting book-keeping can be tedious and difficult to get
+  right. Hence the panels library.</p>
+
+  <p>The <code>panel</code> library first appeared in AT&amp;T
+  System V. The version documented here is the <code>panel</code>
+  code distributed with <code>ncurses</code>.</p>
+
+  <h3><a name="pcompile" id="pcompile">Compiling With the Panels
+  Library</a></h3>
+
+  <p>Your panels-using modules must import the panels library
+  declarations with</p>
+
+  <pre class="code-block">
+          #include &lt;panel.h&gt;
+</pre>
+  <p>and must be linked explicitly with the panels library using an
+  <code>-lpanel</code> argument. Note that they must also link the
+  <code>ncurses</code> library with <code>-lncurses</code>. Many
+  linkers are two-pass and will accept either order, but it is
+  still good practice to put <code>-lpanel</code> first and
+  <code>-lncurses</code> second.</p>
+
+  <h3><a name="poverview" id="poverview">Overview of Panels</a></h3>
+
+  <p>A panel object is a window that is implicitly treated as part
+  of a <dfn>deck</dfn> including all other panel objects. The deck
+  has an implicit bottom-to-top visibility order. The panels
+  library includes an update function (analogous to
+  <code>refresh()</code>) that displays all panels in the deck in
+  the proper order to resolve overlaps. The standard window,
+  <code>stdscr</code>, is considered below all panels.</p>
+
+  <p>Details on the panels functions are available in the man
+  pages. We will just hit the highlights here.</p>
+
+  <p>You create a panel from a window by calling
+  <code>new_panel()</code> on a window pointer. It then becomes the
+  top of the deck. The panel's window is available as the value of
+  <code>panel_window()</code> called with the panel pointer as
+  argument.</p>
+
+  <p>You can delete a panel (removing it from the deck) with
+  <code>del_panel</code>. This will not deallocate the associated
+  window; you have to do that yourself. You can replace a panel's
+  window with a different window by calling
+  <code>replace_window</code>. The new window may be of different
+  size; the panel code will re-compute all overlaps. This operation
+  does not change the panel's position in the deck.</p>
+
+  <p>To move a panel's window, use <code>move_panel()</code>. The
+  <code>mvwin()</code> function on the panel's window is not
+  sufficient because it does not update the panels library's
+  representation of where the windows are. This operation leaves
+  the panel's depth, contents, and size unchanged.</p>
+
+  <p>Two functions (<code>top_panel()</code>,
+  <code>bottom_panel()</code>) are provided for rearranging the
+  deck. The first pops its argument window to the top of the deck;
+  the second sends it to the bottom. Either operation leaves the
+  panel's screen location, contents, and size unchanged.</p>
+
+  <p>The function <code>update_panels()</code> does all the
+  <code>wnoutrefresh()</code> calls needed to prepare for
+  <code>doupdate()</code> (which you must call yourself,
+  afterwards).</p>
+
+  <p>Typically, you will want to call <code>update_panels()</code>
+  and <code>doupdate()</code> just before accepting command input,
+  once in each cycle of interaction with the user. If you call
+  <code>update_panels()</code> after each and every panel write,
+  you will generate a lot of unnecessary refresh activity and
+  screen flicker.</p>
+
+  <h3><a name="pstdscr" id="pstdscr">Panels, Input, and the
+  Standard Screen</a></h3>
+
+  <p>You should not mix <code>wnoutrefresh()</code> or
+  <code>wrefresh()</code> operations with panels code; this will
+  work only if the argument window is either in the top panel or
+  unobscured by any other panels.</p>
+
+  <p>The <code>stsdcr</code> window is a special case. It is
+  considered below all panels. Because changes to panels may
+  obscure parts of <code>stdscr</code>, though, you should call
+  <code>update_panels()</code> before <code>doupdate()</code> even
+  when you only change <code>stdscr</code>.</p>
+
+  <p>Note that <code>wgetch</code> automatically calls
+  <code>wrefresh</code>. Therefore, before requesting input from a
+  panel window, you need to be sure that the panel is totally
+  unobscured.</p>
+
+  <p>There is presently no way to display changes to one obscured
+  panel without repainting all panels.</p>
+
+  <h3><a name="hiding" id="hiding">Hiding Panels</a></h3>
+
+  <p>It is possible to remove a panel from the deck temporarily;
+  use <code>hide_panel</code> for this. Use
+  <code>show_panel()</code> to render it visible again. The
+  predicate function <code>panel_hidden</code> tests whether or not
+  a panel is hidden.</p>
+
+  <p>The <code>panel_update</code> code ignores hidden panels. You
+  cannot do <code>top_panel()</code> or <code>bottom_panel</code>
+  on a hidden panel(). Other panels operations are applicable.</p>
+
+  <h3><a name="pmisc" id="pmisc">Miscellaneous Other Facilities</a></h3>
+
+  <p>It is possible to navigate the deck using the functions
+  <code>panel_above()</code> and <code>panel_below</code>. Handed a
+  panel pointer, they return the panel above or below that panel.
+  Handed <code>NULL</code>, they return the bottom-most or top-most
+  panel.</p>
+
+  <p>Every panel has an associated user pointer, not used by the
+  panel code, to which you can attach application data. See the man
+  page documentation of <code>set_panel_userptr()</code> and
+  <code>panel_userptr</code> for details.</p>
+
+  <h2><a name="menu" id="menu">The Menu Library</a></h2>
+
+  <p>A menu is a screen display that assists the user to choose
+  some subset of a given set of items. The <code>menu</code>
+  library is a curses extension that supports easy programming of
+  menu hierarchies with a uniform but flexible interface.</p>
+
+  <p>The <code>menu</code> library first appeared in AT&amp;T
+  System V. The version documented here is the <code>menu</code>
+  code distributed with <code>ncurses</code>.</p>
+
+  <h3><a name="mcompile" id="mcompile">Compiling With the menu
+  Library</a></h3>
+
+  <p>Your menu-using modules must import the menu library
+  declarations with</p>
+
+  <pre class="code-block">
+          #include &lt;menu.h&gt;
+</pre>
+  <p>and must be linked explicitly with the menus library using an
+  <code>-lmenu</code> argument. Note that they must also link the
+  <code>ncurses</code> library with <code>-lncurses</code>. Many
+  linkers are two-pass and will accept either order, but it is
+  still good practice to put <code>-lmenu</code> first and
+  <code>-lncurses</code> second.</p>
+
+  <h3><a name="moverview" id="moverview">Overview of Menus</a></h3>
+
+  <p>The menus created by this library consist of collections of
+  <dfn>items</dfn> including a name string part and a description
+  string part. To make menus, you create groups of these items and
+  connect them with menu frame objects.</p>
+
+  <p>The menu can then by <dfn>posted</dfn>, that is written to an
+  associated window. Actually, each menu has two associated
+  windows; a containing window in which the programmer can scribble
+  titles or borders, and a subwindow in which the menu items proper
+  are displayed. If this subwindow is too small to display all the
+  items, it will be a scrollable viewport on the collection of
+  items.</p>
+
+  <p>A menu may also be <dfn>unposted</dfn> (that is, undisplayed),
+  and finally freed to make the storage associated with it and its
+  items available for re-use.</p>
+
+  <p>The general flow of control of a menu program looks like
+  this:</p>
+
+  <ol>
+    <li>Initialize <code>curses</code>.</li>
+
+    <li>Create the menu items, using <code>new_item()</code>.</li>
+
+    <li>Create the menu using <code>new_menu()</code>.</li>
+
+    <li>Post the menu using <code>post_menu()</code>.</li>
+
+    <li>Refresh the screen.</li>
+
+    <li>Process user requests via an input loop.</li>
+
+    <li>Unpost the menu using <code>unpost_menu()</code>.</li>
+
+    <li>Free the menu, using <code>free_menu()</code>.</li>
+
+    <li>Free the items using <code>free_item()</code>.</li>
+
+    <li>Terminate <code>curses</code>.</li>
+  </ol>
+
+  <h3><a name="mselect" id="mselect">Selecting items</a></h3>
+
+  <p>Menus may be multi-valued or (the default) single-valued (see
+  the manual page <code>menu_opts(3x)</code> to see how to change
+  the default). Both types always have a <dfn>current
+  item</dfn>.</p>
+
+  <p>From a single-valued menu you can read the selected value
+  simply by looking at the current item. From a multi-valued menu,
+  you get the selected set by looping through the items applying
+  the <code>item_value()</code> predicate function. Your
+  menu-processing code can use the function
+  <code>set_item_value()</code> to flag the items in the select
+  set.</p>
+
+  <p>Menu items can be made unselectable using
+  <code>set_item_opts()</code> or <code>item_opts_off()</code> with
+  the <code>O_SELECTABLE</code> argument. This is the only option
+  so far defined for menus, but it is good practice to code as
+  though other option bits might be on.</p>
+
+  <h3><a name="mdisplay" id="mdisplay">Menu Display</a></h3>
+
+  <p>The menu library calculates a minimum display size for your
+  window, based on the following variables:</p>
+
+  <ul>
+    <li>The number and maximum length of the menu items</li>
+
+    <li>Whether the O_ROWMAJOR option is enabled</li>
+
+    <li>Whether display of descriptions is enabled</li>
+
+    <li>Whatever menu format may have been set by the
+    programmer</li>
+
+    <li>The length of the menu mark string used for highlighting
+    selected items</li>
+  </ul>
+
+  <p>The function <code>set_menu_format()</code> allows you to set
+  the maximum size of the viewport or <dfn>menu page</dfn> that
+  will be used to display menu items. You can retrieve any format
+  associated with a menu with <code>menu_format()</code>. The
+  default format is rows=16, columns=1.</p>
+
+  <p>The actual menu page may be smaller than the format size. This
+  depends on the item number and size and whether O_ROWMAJOR is on.
+  This option (on by default) causes menu items to be displayed in
+  a &ldquo;raster-scan&rdquo; pattern, so that if more than one
+  item will fit horizontally the first couple of items are
+  side-by-side in the top row. The alternative is column-major
+  display, which tries to put the first several items in the first
+  column.</p>
+
+  <p>As mentioned above, a menu format not large enough to allow
+  all items to fit on-screen will result in a menu display that is
+  vertically scrollable.</p>
+
+  <p>You can scroll it with requests to the menu driver, which will
+  be described in the section on <a href="#minput">menu input
+  handling</a>.</p>
+
+  <p>Each menu has a <dfn>mark string</dfn> used to visually tag
+  selected items; see the <code>menu_mark(3x)</code> manual page
+  for details. The mark string length also influences the menu page
+  size.</p>
+
+  <p>The function <code>scale_menu()</code> returns the minimum
+  display size that the menu code computes from all these factors.
+  There are other menu display attributes including a select
+  attribute, an attribute for selectable items, an attribute for
+  unselectable items, and a pad character used to separate item
+  name text from description text. These have reasonable defaults
+  which the library allows you to change (see the
+  <code>menu_attribs(3x)</code> manual page.</p>
+
+  <h3><a name="mwindows" id="mwindows">Menu Windows</a></h3>
+
+  <p>Each menu has, as mentioned previously, a pair of associated
+  windows. Both these windows are painted when the menu is posted
+  and erased when the menu is unposted.</p>
+
+  <p>The outer or frame window is not otherwise touched by the menu
+  routines. It exists so the programmer can associate a title, a
+  border, or perhaps help text with the menu and have it properly
+  refreshed or erased at post/unpost time. The inner window or
+  <dfn>subwindow</dfn> is where the current menu page is
+  displayed.</p>
+
+  <p>By default, both windows are <code>stdscr</code>. You can set
+  them with the functions in <code>menu_win(3x)</code>.</p>
+
+  <p>When you call <code>post_menu()</code>, you write the menu to
+  its subwindow. When you call <code>unpost_menu()</code>, you
+  erase the subwindow, However, neither of these actually modifies
+  the screen. To do that, call <code>wrefresh()</code> or some
+  equivalent.</p>
+
+  <h3><a name="minput" id="minput">Processing Menu Input</a></h3>
+
+  <p>The main loop of your menu-processing code should call
+  <code>menu_driver()</code> repeatedly. The first argument of this
+  routine is a menu pointer; the second is a menu command code. You
+  should write an input-fetching routine that maps input characters
+  to menu command codes, and pass its output to
+  <code>menu_driver()</code>. The menu command codes are fully
+  documented in <code>menu_driver(3x)</code>.</p>
+
+  <p>The simplest group of command codes is
+  <code>REQ_NEXT_ITEM</code>, <code>REQ_PREV_ITEM</code>,
+  <code>REQ_FIRST_ITEM</code>, <code>REQ_LAST_ITEM</code>,
+  <code>REQ_UP_ITEM</code>, <code>REQ_DOWN_ITEM</code>,
+  <code>REQ_LEFT_ITEM</code>, <code>REQ_RIGHT_ITEM</code>. These
+  change the currently selected item. These requests may cause
+  scrolling of the menu page if it only partially displayed.</p>
+
+  <p>There are explicit requests for scrolling which also change
+  the current item (because the select location does not change,
+  but the item there does). These are <code>REQ_SCR_DLINE</code>,
+  <code>REQ_SCR_ULINE</code>, <code>REQ_SCR_DPAGE</code>, and
+  <code>REQ_SCR_UPAGE</code>.</p>
+
+  <p>The <code>REQ_TOGGLE_ITEM</code> selects or deselects the
+  current item. It is for use in multi-valued menus; if you use it
+  with <code>O_ONEVALUE</code> on, you will get an error return
+  (<code>E_REQUEST_DENIED</code>).</p>
+
+  <p>Each menu has an associated pattern buffer. The
+  <code>menu_driver()</code> logic tries to accumulate printable
+  ASCII characters passed in in that buffer; when it matches a
+  prefix of an item name, that item (or the next matching item) is
+  selected. If appending a character yields no new match, that
+  character is deleted from the pattern buffer, and
+  <code>menu_driver()</code> returns <code>E_NO_MATCH</code>.</p>
+
+  <p>Some requests change the pattern buffer directly:
+  <code>REQ_CLEAR_PATTERN</code>, <code>REQ_BACK_PATTERN</code>,
+  <code>REQ_NEXT_MATCH</code>, <code>REQ_PREV_MATCH</code>. The
+  latter two are useful when pattern buffer input matches more than
+  one item in a multi-valued menu.</p>
+
+  <p>Each successful scroll or item navigation request clears the
+  pattern buffer. It is also possible to set the pattern buffer
+  explicitly with <code>set_menu_pattern()</code>.</p>
+
+  <p>Finally, menu driver requests above the constant
+  <code>MAX_COMMAND</code> are considered application-specific
+  commands. The <code>menu_driver()</code> code ignores them and
+  returns <code>E_UNKNOWN_COMMAND</code>.</p>
+
+  <h3><a name="mmisc" id="mmisc">Miscellaneous Other Features</a></h3>
+
+  <p>Various menu options can affect the processing and visual
+  appearance and input processing of menus. See <code>menu_opts(3x)
+  for details.</code></p>
+
+  <p>It is possible to change the current item from application
+  code; this is useful if you want to write your own navigation
+  requests. It is also possible to explicitly set the top row of
+  the menu display. See <code>mitem_current(3x)</code>. If your
+  application needs to change the menu subwindow cursor for any
+  reason, <code>pos_menu_cursor()</code> will restore it to the
+  correct location for continuing menu driver processing.</p>
+
+  <p>It is possible to set hooks to be called at menu
+  initialization and wrapup time, and whenever the selected item
+  changes. See <code>menu_hook(3x)</code>.</p>
+
+  <p>Each item, and each menu, has an associated user pointer on
+  which you can hang application data. See
+  <code>mitem_userptr(3x)</code> and
+  <code>menu_userptr(3x)</code>.</p>
+
+  <h2><a name="form" id="form">The Forms Library</a></h2>
+
+  <p>The <code>form</code> library is a curses extension that
+  supports easy programming of on-screen forms for data entry and
+  program control.</p>
+
+  <p>The <code>form</code> library first appeared in AT&amp;T
+  System V. The version documented here is the <code>form</code>
+  code distributed with <code>ncurses</code>.</p>
+
+  <h3><a name="fcompile" id="fcompile">Compiling With the form
+  Library</a></h3>
+
+  <p>Your form-using modules must import the form library
+  declarations with</p>
+
+  <pre class="code-block">
+          #include &lt;form.h&gt;
+</pre>
+  <p>and must be linked explicitly with the forms library using an
+  <code>-lform</code> argument. Note that they must also link the
+  <code>ncurses</code> library with <code>-lncurses</code>. Many
+  linkers are two-pass and will accept either order, but it is
+  still good practice to put <code>-lform</code> first and
+  <code>-lncurses</code> second.</p>
+
+  <h3><a name="foverview" id="foverview">Overview of Forms</a></h3>
+
+  <p>A form is a collection of fields; each field may be either a
+  label (explanatory text) or a data-entry location. Long forms may
+  be segmented into pages; each entry to a new page clears the
+  screen.</p>
+
+  <p>To make forms, you create groups of fields and connect them
+  with form frame objects; the form library makes this relatively
+  simple.</p>
+
+  <p>Once defined, a form can be <dfn>posted</dfn>, that is written
+  to an associated window. Actually, each form has two associated
+  windows; a containing window in which the programmer can scribble
+  titles or borders, and a subwindow in which the form fields
+  proper are displayed.</p>
+
+  <p>As the form user fills out the posted form, navigation and
+  editing keys support movement between fields, editing keys
+  support modifying field, and plain text adds to or changes data
+  in a current field. The form library allows you (the forms
+  designer) to bind each navigation and editing key to any
+  keystroke accepted by <code>curses</code> Fields may have
+  validation conditions on them, so that they check input data for
+  type and value. The form library supplies a rich set of
+  pre-defined field types, and makes it relatively easy to define
+  new ones.</p>
+
+  <p>Once its transaction is completed (or aborted), a form may be
+  <dfn>unposted</dfn> (that is, undisplayed), and finally freed to
+  make the storage associated with it and its items available for
+  re-use.</p>
+
+  <p>The general flow of control of a form program looks like
+  this:</p>
+
+  <ol>
+    <li>Initialize <code>curses</code>.</li>
+
+    <li>Create the form fields, using
+    <code>new_field()</code>.</li>
+
+    <li>Create the form using <code>new_form()</code>.</li>
+
+    <li>Post the form using <code>post_form()</code>.</li>
+
+    <li>Refresh the screen.</li>
+
+    <li>Process user requests via an input loop.</li>
+
+    <li>Unpost the form using <code>unpost_form()</code>.</li>
+
+    <li>Free the form, using <code>free_form()</code>.</li>
+
+    <li>Free the fields using <code>free_field()</code>.</li>
+
+    <li>Terminate <code>curses</code>.</li>
+  </ol>
+
+  <p>Note that this looks much like a menu program; the form
+  library handles tasks which are in many ways similar, and its
+  interface was obviously designed to resemble that of the <a href=
+  "#menu">menu library</a> wherever possible.</p>
+
+  <p>In forms programs, however, the &ldquo;process user
+  requests&rdquo; is somewhat more complicated than for menus.
+  Besides menu-like navigation operations, the menu driver loop has
+  to support field editing and data validation.</p>
+
+  <h3><a name="fcreate" id="fcreate">Creating and Freeing Fields
+  and Forms</a></h3>
+
+  <p>The basic function for creating fields is
+  <code>new_field()</code>:</p>
+
+  <pre class="code-block">
+FIELD *new_field(int height, int width,   /* new field size */
+                 int top, int left,       /* upper left corner */
+                 int offscreen,           /* number of offscreen rows */
+                 int nbuf);               /* number of working buffers */
+</pre>
+  <p>Menu items always occupy a single row, but forms fields may
+  have multiple rows. So <code>new_field()</code> requires you to
+  specify a width and height (the first two arguments, which mist
+  both be greater than zero).</p>
+
+  <p>You must also specify the location of the field's upper left
+  corner on the screen (the third and fourth arguments, which must
+  be zero or greater). Note that these coordinates are relative to
+  the form subwindow, which will coincide with <code>stdscr</code>
+  by default but need not be <code>stdscr</code> if you have done
+  an explicit <code>set_form_win()</code> call.</p>
+
+  <p>The fifth argument allows you to specify a number of
+  off-screen rows. If this is zero, the entire field will always be
+  displayed. If it is nonzero, the form will be scrollable, with
+  only one screen-full (initially the top part) displayed at any
+  given time. If you make a field dynamic and grow it so it will no
+  longer fit on the screen, the form will become scrollable even if
+  the <code>offscreen</code> argument was initially zero.</p>
+
+  <p>The forms library allocates one working buffer per field; the
+  size of each buffer is <code>((height + offscreen)*width +
+  1</code>, one character for each position in the field plus a NUL
+  terminator. The sixth argument is the number of additional data
+  buffers to allocate for the field; your application can use them
+  for its own purposes.</p>
+
+  <pre class="code-block">
+FIELD *dup_field(FIELD *field,            /* field to copy */
+                 int top, int left);      /* location of new copy */
+</pre>
+  <p>The function <code>dup_field()</code> duplicates an existing
+  field at a new location. Size and buffering information are
+  copied; some attribute flags and status bits are not (see the
+  <code>form_field_new(3X)</code> for details).</p>
+
+  <pre class="code-block">
+FIELD *link_field(FIELD *field,           /* field to copy */
+                  int top, int left);     /* location of new copy */
+</pre>
+  <p>The function <code>link_field()</code> also duplicates an
+  existing field at a new location. The difference from
+  <code>dup_field()</code> is that it arranges for the new field's
+  buffer to be shared with the old one.</p>
+
+  <p>Besides the obvious use in making a field editable from two
+  different form pages, linked fields give you a way to hack in
+  dynamic labels. If you declare several fields linked to an
+  original, and then make them inactive, changes from the original
+  will still be propagated to the linked fields.</p>
+
+  <p>As with duplicated fields, linked fields have attribute bits
+  separate from the original.</p>
+
+  <p>As you might guess, all these field-allocations return
+  <code>NULL</code> if the field allocation is not possible due to
+  an out-of-memory error or out-of-bounds arguments.</p>
+
+  <p>To connect fields to a form, use</p>
+
+  <pre class="code-block">
+FORM *new_form(FIELD **fields);
+</pre>
+  <p>This function expects to see a NULL-terminated array of field
+  pointers. Said fields are connected to a newly-allocated form
+  object; its address is returned (or else NULL if the allocation
+  fails).</p>
+
+  <p>Note that <code>new_field()</code> does <em>not</em> copy the
+  pointer array into private storage; if you modify the contents of
+  the pointer array during forms processing, all manner of bizarre
+  things might happen. Also note that any given field may only be
+  connected to one form.</p>
+
+  <p>The functions <code>free_field()</code> and
+  <code>free_form</code> are available to free field and form
+  objects. It is an error to attempt to free a field connected to a
+  form, but not vice-versa; thus, you will generally free your form
+  objects first.</p>
+
+  <h3><a name="fattributes" id="fattributes">Fetching and Changing
+  Field Attributes</a></h3>
+
+  <p>Each form field has a number of location and size attributes
+  associated with it. There are other field attributes used to
+  control display and editing of the field. Some (for example, the
+  <code>O_STATIC</code> bit) involve sufficient complications to be
+  covered in sections of their own later on. We cover the functions
+  used to get and set several basic attributes here.</p>
+
+  <p>When a field is created, the attributes not specified by the
+  <code>new_field</code> function are copied from an invisible
+  system default field. In attribute-setting and -fetching
+  functions, the argument NULL is taken to mean this field. Changes
+  to it persist as defaults until your forms application
+  terminates.</p>
+
+  <h4><a name="fsizes" id="fsizes">Fetching Size and Location
+  Data</a></h4>
+
+  <p>You can retrieve field sizes and locations through:</p>
+
+  <pre class="code-block">
+int field_info(FIELD *field,              /* field from which to fetch */
+               int *height, *int width,   /* field size */
+               int *top, int *left,       /* upper left corner */
+               int *offscreen,            /* number of offscreen rows */
+               int *nbuf);                /* number of working buffers */
+</pre>
+  <p>This function is a sort of inverse of
+  <code>new_field()</code>; instead of setting size and location
+  attributes of a new field, it fetches them from an existing
+  one.</p>
+
+  <h4><a name="flocation" id="flocation">Changing the Field
+  Location</a></h4>
+
+  <p>It is possible to move a field's location on the screen:</p>
+
+  <pre class="code-block">
+int move_field(FIELD *field,              /* field to alter */
+               int top, int left);        /* new upper-left corner */
+</pre>
+  <p>You can, of course. query the current location through
+  <code>field_info()</code>.</p>
+
+  <h4><a name="fjust" id="fjust">The Justification Attribute</a></h4>
+
+  <p>One-line fields may be unjustified, justified right, justified
+  left, or centered. Here is how you manipulate this attribute:</p>
+
+  <pre class="code-block">
+int set_field_just(FIELD *field,          /* field to alter */
+                   int justmode);         /* mode to set */
+
+int field_just(FIELD *field);             /* fetch mode of field */
+</pre>
+  <p>The mode values accepted and returned by this functions are
+  preprocessor macros <code>NO_JUSTIFICATION</code>,
+  <code>JUSTIFY_RIGHT</code>, <code>JUSTIFY_LEFT</code>, or
+  <code>JUSTIFY_CENTER</code>.</p>
+
+  <h4><a name="fdispatts" id="fdispatts">Field Display
+  Attributes</a></h4>
+
+  <p>For each field, you can set a foreground attribute for entered
+  characters, a background attribute for the entire field, and a
+  pad character for the unfilled portion of the field. You can also
+  control pagination of the form.</p>
+
+  <p>This group of four field attributes controls the visual
+  appearance of the field on the screen, without affecting in any
+  way the data in the field buffer.</p>
+
+  <pre class="code-block">
+int set_field_fore(FIELD *field,          /* field to alter */
+                   chtype attr);          /* attribute to set */
+
+chtype field_fore(FIELD *field);          /* field to query */
+
+int set_field_back(FIELD *field,          /* field to alter */
+                   chtype attr);          /* attribute to set */
+
+chtype field_back(FIELD *field);          /* field to query */
+
+int set_field_pad(FIELD *field,           /* field to alter */
+                 int pad);                /* pad character to set */
+
+chtype field_pad(FIELD *field);
+
+int set_new_page(FIELD *field,            /* field to alter */
+                 int flag);               /* TRUE to force new page */
+
+chtype new_page(FIELD *field);            /* field to query */
+</pre>
+  <p>The attributes set and returned by the first four functions
+  are normal <code>curses(3x)</code> display attribute values
+  (<code>A_STANDOUT</code>, <code>A_BOLD</code>,
+  <code>A_REVERSE</code> etc). The page bit of a field controls
+  whether it is displayed at the start of a new form screen.</p>
+
+  <h4><a name="foptions" id="foptions">Field Option Bits</a></h4>
+
+  <p>There is also a large collection of field option bits you can
+  set to control various aspects of forms processing. You can
+  manipulate them with these functions:</p>
+
+  <pre class="code-block">
+int set_field_opts(FIELD *field,          /* field to alter */
+                   int attr);             /* attribute to set */
+
+int field_opts_on(FIELD *field,           /* field to alter */
+                  int attr);              /* attributes to turn on */
+
+int field_opts_off(FIELD *field,          /* field to alter */
+                   int attr);             /* attributes to turn off */
+
+int field_opts(FIELD *field);             /* field to query */
+</pre>
+  <p>By default, all options are on. Here are the available option
+  bits:</p>
+
+  <dl>
+    <dt>O_VISIBLE</dt>
+
+    <dd>Controls whether the field is visible on the screen. Can be
+    used during form processing to hide or pop up fields depending
+    on the value of parent fields.</dd>
+
+    <dt>O_ACTIVE</dt>
+
+    <dd>Controls whether the field is active during forms
+    processing (i.e. visited by form navigation keys). Can be used
+    to make labels or derived fields with buffer values alterable
+    by the forms application, not the user.</dd>
+
+    <dt>O_PUBLIC</dt>
+
+    <dd>Controls whether data is displayed during field entry. If
+    this option is turned off on a field, the library will accept
+    and edit data in that field, but it will not be displayed and
+    the visible field cursor will not move. You can turn off the
+    O_PUBLIC bit to define password fields.</dd>
+
+    <dt>O_EDIT</dt>
+
+    <dd>Controls whether the field's data can be modified. When
+    this option is off, all editing requests except
+    <code>REQ_PREV_CHOICE</code> and <code>REQ_NEXT_CHOICE</code>
+    will fail. Such read-only fields may be useful for help
+    messages.</dd>
+
+    <dt>O_WRAP</dt>
+
+    <dd>Controls word-wrapping in multi-line fields. Normally, when
+    any character of a (blank-separated) word reaches the end of
+    the current line, the entire word is wrapped to the next line
+    (assuming there is one). When this option is off, the word will
+    be split across the line break.</dd>
+
+    <dt>O_BLANK</dt>
+
+    <dd>Controls field blanking. When this option is on, entering a
+    character at the first field position erases the entire field
+    (except for the just-entered character).</dd>
+
+    <dt>O_AUTOSKIP</dt>
+
+    <dd>Controls automatic skip to next field when this one fills.
+    Normally, when the forms user tries to type more data into a
+    field than will fit, the editing location jumps to next field.
+    When this option is off, the user's cursor will hang at the end
+    of the field. This option is ignored in dynamic fields that
+    have not reached their size limit.</dd>
+
+    <dt>O_NULLOK</dt>
+
+    <dd>Controls whether <a href="#fvalidation">validation</a> is
+    applied to blank fields. Normally, it is not; the user can
+    leave a field blank without invoking the usual validation check
+    on exit. If this option is off on a field, exit from it will
+    invoke a validation check.</dd>
+
+    <dt>O_PASSOK</dt>
+
+    <dd>Controls whether validation occurs on every exit, or only
+    after the field is modified. Normally the latter is true.
+    Setting O_PASSOK may be useful if your field's validation
+    function may change during forms processing.</dd>
+
+    <dt>O_STATIC</dt>
+
+    <dd>Controls whether the field is fixed to its initial
+    dimensions. If you turn this off, the field becomes <a href=
+    "#fdynamic">dynamic</a> and will stretch to fit entered
+    data.</dd>
+  </dl>
+
+  <p>A field's options cannot be changed while the field is
+  currently selected. However, options may be changed on posted
+  fields that are not current.</p>
+
+  <p>The option values are bit-masks and can be composed with
+  logical-or in the obvious way.</p>
+
+  <h3><a name="fstatus" id="fstatus">Field Status</a></h3>
+
+  <p>Every field has a status flag, which is set to FALSE when the
+  field is created and TRUE when the value in field buffer 0
+  changes. This flag can be queried and set directly:</p>
+
+  <pre class="code-block">
+int set_field_status(FIELD *field,      /* field to alter */
+                   int status);         /* mode to set */
+
+int field_status(FIELD *field);         /* fetch mode of field */
+</pre>
+  <p>Setting this flag under program control can be useful if you
+  use the same form repeatedly, looking for modified fields each
+  time.</p>
+
+  <p>Calling <code>field_status()</code> on a field not currently
+  selected for input will return a correct value. Calling
+  <code>field_status()</code> on a field that is currently selected
+  for input may not necessarily give a correct field status value,
+  because entered data is not necessarily copied to buffer zero
+  before the exit validation check. To guarantee that the returned
+  status value reflects reality, call <code>field_status()</code>
+  either (1) in the field's exit validation check routine, (2) from
+  the field's or form's initialization or termination hooks, or (3)
+  just after a <code>REQ_VALIDATION</code> request has been
+  processed by the forms driver.</p>
+
+  <h3><a name="fuser" id="fuser">Field User Pointer</a></h3>
+
+  <p>Each field structure contains one character pointer slot that
+  is not used by the forms library. It is intended to be used by
+  applications to store private per-field data. You can manipulate
+  it with:</p>
+
+  <pre class="code-block">
+int set_field_userptr(FIELD *field,       /* field to alter */
+                   char *userptr);        /* mode to set */
+
+char *field_userptr(FIELD *field);        /* fetch mode of field */
+</pre>(Properly, this user pointer field ought to have <code>(void
+*)</code> type. The <code>(char *)</code> type is retained for
+System V compatibility.)
+  <p>It is valid to set the user pointer of the default field (with
+  a <code>set_field_userptr()</code> call passed a NULL field
+  pointer.) When a new field is created, the default-field user
+  pointer is copied to initialize the new field's user pointer.</p>
+
+  <h3><a name="fdynamic" id="fdynamic">Variable-Sized Fields</a></h3>
+
+  <p>Normally, a field is fixed at the size specified for it at
+  creation time. If, however, you turn off its O_STATIC bit, it
+  becomes <dfn>dynamic</dfn> and will automatically resize itself
+  to accommodate data as it is entered. If the field has extra
+  buffers associated with it, they will grow right along with the
+  main input buffer.</p>
+
+  <p>A one-line dynamic field will have a fixed height (1) but
+  variable width, scrolling horizontally to display data within the
+  field area as originally dimensioned and located. A multi-line
+  dynamic field will have a fixed width, but variable height
+  (number of rows), scrolling vertically to display data within the
+  field area as originally dimensioned and located.</p>
+
+  <p>Normally, a dynamic field is allowed to grow without limit.
+  But it is possible to set an upper limit on the size of a dynamic
+  field. You do it with this function:</p>
+
+  <pre class="code-block">
+int set_max_field(FIELD *field,     /* field to alter (may not be NULL) */
+                   int max_size);   /* upper limit on field size */
+</pre>
+  <p>If the field is one-line, <code>max_size</code> is taken to be
+  a column size limit; if it is multi-line, it is taken to be a
+  line size limit. To disable any limit, use an argument of zero.
+  The growth limit can be changed whether or not the O_STATIC bit
+  is on, but has no effect until it is.</p>
+
+  <p>The following properties of a field change when it becomes
+  dynamic:</p>
+
+  <ul>
+    <li>If there is no growth limit, there is no final position of
+    the field; therefore <code>O_AUTOSKIP</code> and
+    <code>O_NL_OVERLOAD</code> are ignored.</li>
+
+    <li>Field justification will be ignored (though whatever
+    justification is set up will be retained internally and can be
+    queried).</li>
+
+    <li>The <code>dup_field()</code> and <code>link_field()</code>
+    calls copy dynamic-buffer sizes. If the <code>O_STATIC</code>
+    option is set on one of a collection of links, buffer resizing
+    will occur only when the field is edited through that
+    link.</li>
+
+    <li>The call <code>field_info()</code> will retrieve the
+    original static size of the field; use
+    <code>dynamic_field_info()</code> to get the actual dynamic
+    size.</li>
+  </ul>
+
+  <h3><a name="fvalidation" id="fvalidation">Field Validation</a></h3>
+
+  <p>By default, a field will accept any data that will fit in its
+  input buffer. However, it is possible to attach a validation type
+  to a field. If you do this, any attempt to leave the field while
+  it contains data that does not match the validation type will
+  fail. Some validation types also have a character-validity check
+  for each time a character is entered in the field.</p>
+
+  <p>A field's validation check (if any) is not called when
+  <code>set_field_buffer()</code> modifies the input buffer, nor
+  when that buffer is changed through a linked field.</p>
+
+  <p>The <code>form</code> library provides a rich set of
+  pre-defined validation types, and gives you the capability to
+  define custom ones of your own. You can examine and change field
+  validation attributes with the following functions:</p>
+
+  <pre class="code-block">
+int set_field_type(FIELD *field,          /* field to alter */
+                   FIELDTYPE *ftype,      /* type to associate */
+                   ...);                  /* additional arguments*/
+
+FIELDTYPE *field_type(FIELD *field);      /* field to query */
+</pre>
+  <p>The validation type of a field is considered an attribute of
+  the field. As with other field attributes, Also, doing
+  <code>set_field_type()</code> with a <code>NULL</code> field
+  default will change the system default for validation of
+  newly-created fields.</p>
+
+  <p>Here are the pre-defined validation types:</p>
+
+  <h4><a name="ftype_alpha" id="ftype_alpha">TYPE_ALPHA</a></h4>
+
+  <p>This field type accepts alphabetic data; no blanks, no digits,
+  no special characters (this is checked at character-entry time).
+  It is set up with:</p>
+
+  <pre class="code-block">
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_ALPHA,            /* type to associate */
+                   int width);            /* maximum width of field */
+</pre>
+  <p>The <code>width</code> argument sets a minimum width of data.
+  Typically you will want to set this to the field width; if it is
+  greater than the field width, the validation check will always
+  fail. A minimum width of zero makes field completion
+  optional.</p>
+
+  <h4><a name="ftype_alnum" id="ftype_alnum">TYPE_ALNUM</a></h4>
+
+  <p>This field type accepts alphabetic data and digits; no blanks,
+  no special characters (this is checked at character-entry time).
+  It is set up with:</p>
+
+  <pre class="code-block">
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_ALNUM,            /* type to associate */
+                   int width);            /* maximum width of field */
+</pre>
+  <p>The <code>width</code> argument sets a minimum width of data.
+  As with TYPE_ALPHA, typically you will want to set this to the
+  field width; if it is greater than the field width, the
+  validation check will always fail. A minimum width of zero makes
+  field completion optional.</p>
+
+  <h4><a name="ftype_enum" id="ftype_enum">TYPE_ENUM</a></h4>
+
+  <p>This type allows you to restrict a field's values to be among
+  a specified set of string values (for example, the two-letter
+  postal codes for U.S. states). It is set up with:</p>
+
+  <pre class="code-block">
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_ENUM,             /* type to associate */
+                   char **valuelist;      /* list of possible values */
+                   int checkcase;         /* case-sensitive? */
+                   int checkunique);      /* must specify uniquely? */
+</pre>
+  <p>The <code>valuelist</code> parameter must point at a
+  NULL-terminated list of valid strings. The <code>checkcase</code>
+  argument, if true, makes comparison with the string
+  case-sensitive.</p>
+
+  <p>When the user exits a TYPE_ENUM field, the validation
+  procedure tries to complete the data in the buffer to a valid
+  entry. If a complete choice string has been entered, it is of
+  course valid. But it is also possible to enter a prefix of a
+  valid string and have it completed for you.</p>
+
+  <p>By default, if you enter such a prefix and it matches more
+  than one value in the string list, the prefix will be completed
+  to the first matching value. But the <code>checkunique</code>
+  argument, if true, requires prefix matches to be unique in order
+  to be valid.</p>
+
+  <p>The <code>REQ_NEXT_CHOICE</code> and
+  <code>REQ_PREV_CHOICE</code> input requests can be particularly
+  useful with these fields.</p>
+
+  <h4><a name="ftype_integer" id="ftype_integer">TYPE_INTEGER</a></h4>
+
+  <p>This field type accepts an integer. It is set up as
+  follows:</p>
+
+  <pre class="code-block">
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_INTEGER,          /* type to associate */
+                   int padding,           /* # places to zero-pad to */
+                   int vmin, int vmax);   /* valid range */
+</pre>
+  <p>Valid characters consist of an optional leading minus and
+  digits. The range check is performed on exit. If the range
+  maximum is less than or equal to the minimum, the range is
+  ignored.</p>
+
+  <p>If the value passes its range check, it is padded with as many
+  leading zero digits as necessary to meet the padding
+  argument.</p>
+
+  <p>A <code>TYPE_INTEGER</code> value buffer can conveniently be
+  interpreted with the C library function <code>atoi(3)</code>.</p>
+
+  <h4><a name="ftype_numeric" id="ftype_numeric">TYPE_NUMERIC</a></h4>
+
+  <p>This field type accepts a decimal number. It is set up as
+  follows:</p>
+
+  <pre class="code-block">
+int set_field_type(FIELD *field,              /* field to alter */
+                   TYPE_NUMERIC,              /* type to associate */
+                   int padding,               /* # places of precision */
+                   double vmin, double vmax); /* valid range */
+</pre>
+  <p>Valid characters consist of an optional leading minus and
+  digits. possibly including a decimal point. If your system
+  supports locale's, the decimal point character used must be the
+  one defined by your locale. The range check is performed on exit.
+  If the range maximum is less than or equal to the minimum, the
+  range is ignored.</p>
+
+  <p>If the value passes its range check, it is padded with as many
+  trailing zero digits as necessary to meet the padding
+  argument.</p>
+
+  <p>A <code>TYPE_NUMERIC</code> value buffer can conveniently be
+  interpreted with the C library function <code>atof(3)</code>.</p>
+
+  <h4><a name="ftype_regexp" id="ftype_regexp">TYPE_REGEXP</a></h4>
+
+  <p>This field type accepts data matching a regular expression. It
+  is set up as follows:</p>
+
+  <pre class="code-block">
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_REGEXP,           /* type to associate */
+                   char *regexp);         /* expression to match */
+</pre>
+  <p>The syntax for regular expressions is that of
+  <code>regcomp(3)</code>. The check for regular-expression match
+  is performed on exit.</p>
+
+  <h3><a name="fbuffer" id="fbuffer">Direct Field Buffer
+  Manipulation</a></h3>
+
+  <p>The chief attribute of a field is its buffer contents. When a
+  form has been completed, your application usually needs to know
+  the state of each field buffer. You can find this out with:</p>
+
+  <pre class="code-block">
+char *field_buffer(FIELD *field,          /* field to query */
+                   int bufindex);         /* number of buffer to query */
+</pre>
+  <p>Normally, the state of the zero-numbered buffer for each field
+  is set by the user's editing actions on that field. It is
+  sometimes useful to be able to set the value of the zero-numbered
+  (or some other) buffer from your application:</p>
+
+  <pre class="code-block">
+int set_field_buffer(FIELD *field,        /* field to alter */
+                   int bufindex,          /* number of buffer to alter */
+                   char *value);          /* string value to set */
+</pre>
+  <p>If the field is not large enough and cannot be resized to a
+  sufficiently large size to contain the specified value, the value
+  will be truncated to fit.</p>
+
+  <p>Calling <code>field_buffer()</code> with a null field pointer
+  will raise an error. Calling <code>field_buffer()</code> on a
+  field not currently selected for input will return a correct
+  value. Calling <code>field_buffer()</code> on a field that is
+  currently selected for input may not necessarily give a correct
+  field buffer value, because entered data is not necessarily
+  copied to buffer zero before the exit validation check. To
+  guarantee that the returned buffer value reflects on-screen
+  reality, call <code>field_buffer()</code> either (1) in the
+  field's exit validation check routine, (2) from the field's or
+  form's initialization or termination hooks, or (3) just after a
+  <code>REQ_VALIDATION</code> request has been processed by the
+  forms driver.</p>
+
+  <h3><a name="formattrs" id="formattrs">Attributes of Forms</a></h3>
+
+  <p>As with field attributes, form attributes inherit a default
+  from a system default form structure. These defaults can be
+  queried or set by of these functions using a form-pointer
+  argument of <code>NULL</code>.</p>
+
+  <p>The principal attribute of a form is its field list. You can
+  query and change this list with:</p>
+
+  <pre class="code-block">
+int set_form_fields(FORM *form,           /* form to alter */
+                    FIELD **fields);      /* fields to connect */
+
+char *form_fields(FORM *form);            /* fetch fields of form */
+
+int field_count(FORM *form);              /* count connect fields */
+</pre>
+  <p>The second argument of <code>set_form_fields()</code> may be a
+  NULL-terminated field pointer array like the one required by
+  <code>new_form()</code>. In that case, the old fields of the form
+  are disconnected but not freed (and eligible to be connected to
+  other forms), then the new fields are connected.</p>
+
+  <p>It may also be null, in which case the old fields are
+  disconnected (and not freed) but no new ones are connected.</p>
+
+  <p>The <code>field_count()</code> function simply counts the
+  number of fields connected to a given from. It returns -1 if the
+  form-pointer argument is NULL.</p>
+
+  <h3><a name="fdisplay" id="fdisplay">Control of Form Display</a></h3>
+
+  <p>In the overview section, you saw that to display a form you
+  normally start by defining its size (and fields), posting it, and
+  refreshing the screen. There is an hidden step before posting,
+  which is the association of the form with a frame window
+  (actually, a pair of windows) within which it will be displayed.
+  By default, the forms library associates every form with the
+  full-screen window <code>stdscr</code>.</p>
+
+  <p>By making this step explicit, you can associate a form with a
+  declared frame window on your screen display. This can be useful
+  if you want to adapt the form display to different screen sizes,
+  dynamically tile forms on the screen, or use a form as part of an
+  interface layout managed by <a href="#panels">panels</a>.</p>
+
+  <p>The two windows associated with each form have the same
+  functions as their analogues in the <a href="#menu">menu
+  library</a>. Both these windows are painted when the form is
+  posted and erased when the form is unposted.</p>
+
+  <p>The outer or frame window is not otherwise touched by the form
+  routines. It exists so the programmer can associate a title, a
+  border, or perhaps help text with the form and have it properly
+  refreshed or erased at post/unpost time. The inner window or
+  subwindow is where the current form page is actually
+  displayed.</p>
+
+  <p>In order to declare your own frame window for a form, you will
+  need to know the size of the form's bounding rectangle. You can
+  get this information with:</p>
+
+  <pre class="code-block">
+int scale_form(FORM *form,                /* form to query */
+               int *rows,                 /* form rows */
+               int *cols);                /* form cols */
+</pre>
+  <p>The form dimensions are passed back in the locations pointed
+  to by the arguments. Once you have this information, you can use
+  it to declare of windows, then use one of these functions:</p>
+
+  <pre class="code-block">
+int set_form_win(FORM *form,              /* form to alter */
+                 WINDOW *win);            /* frame window to connect */
+
+WINDOW *form_win(FORM *form);             /* fetch frame window of form */
+
+int set_form_sub(FORM *form,              /* form to alter */
+                 WINDOW *win);            /* form subwindow to connect */
+
+WINDOW *form_sub(FORM *form);             /* fetch form subwindow of form */
+</pre>
+  <p>Note that curses operations, including <code>refresh()</code>,
+  on the form, should be done on the frame window, not the form
+  subwindow.</p>
+
+  <p>It is possible to check from your application whether all of a
+  scrollable field is actually displayed within the menu subwindow.
+  Use these functions:</p>
+
+  <pre class="code-block">
+int data_ahead(FORM *form);               /* form to be queried */
+
+int data_behind(FORM *form);              /* form to be queried */
+</pre>
+  <p>The function <code>data_ahead()</code> returns TRUE if (a) the
+  current field is one-line and has undisplayed data off to the
+  right, (b) the current field is multi-line and there is data
+  off-screen below it.</p>
+
+  <p>The function <code>data_behind()</code> returns TRUE if the
+  first (upper left hand) character position is off-screen (not
+  being displayed).</p>
+
+  <p>Finally, there is a function to restore the form window's
+  cursor to the value expected by the forms driver:</p>
+
+  <pre class="code-block">
+int pos_form_cursor(FORM *)               /* form to be queried */
+</pre>
+  <p>If your application changes the form window cursor, call this
+  function before handing control back to the forms driver in order
+  to re-synchronize it.</p>
+
+  <h3><a name="fdriver" id="fdriver">Input Processing in the Forms
+  Driver</a></h3>
+
+  <p>The function <code>form_driver()</code> handles virtualized
+  input requests for form navigation, editing, and validation
+  requests, just as <code>menu_driver</code> does for menus (see
+  the section on <a href="#minput">menu input handling</a>).</p>
+
+  <pre class="code-block">
+int form_driver(FORM *form,               /* form to pass input to */
+                int request);             /* form request code */
+</pre>
+  <p>Your input virtualization function needs to take input and
+  then convert it to either an alphanumeric character (which is
+  treated as data to be entered in the currently-selected field),
+  or a forms processing request.</p>
+
+  <p>The forms driver provides hooks (through input-validation and
+  field-termination functions) with which your application code can
+  check that the input taken by the driver matched what was
+  expected.</p>
+
+  <h4><a name="fpage" id="fpage">Page Navigation Requests</a></h4>
+
+  <p>These requests cause page-level moves through the form,

+  and <code>REQ_PREV_PAGE</code> from the first page goes to the
+  last.</p>
+
+  <h4><a name="ffield" id="ffield">Inter-Field Navigation

+    <dt><code>REQ_DOWN_FIELD</code>
+    </dt>
+
+    <dd>Move down to field.</dd>
+  </dl>
+
+  <p>These requests treat the list of fields on a page as cyclic;
+  that is, <code>REQ_NEXT_FIELD</code> from the last field goes to
+  the first, and <code>REQ_PREV_FIELD</code> from the first field
+  goes to the last. The order of the fields for these (and the
+  <code>REQ_FIRST_FIELD</code> and <code>REQ_LAST_FIELD</code>
+  requests) is simply the order of the field pointers in the form
+  array (as set up by <code>new_form()</code> or
+  <code>set_form_fields()</code></p>
+
+  <p>It is also possible to traverse the fields as if they had been
+  sorted in screen-position order, so the sequence goes
+  left-to-right and top-to-bottom. To do this, use the second group
+  of four sorted-movement requests.</p>
+
+  <p>Finally, it is possible to move between fields using visual
+  directions up, down, right, and left. To accomplish this, use the
+  third group of four requests. Note, however, that the position of
+  a form for purposes of these requests is its upper-left
+  corner.</p>
+
+  <p>For example, suppose you have a multi-line field B, and two
+  single-line fields A and C on the same line with B, with A to the
+  left of B and C to the right of B. A <code>REQ_MOVE_RIGHT</code>
+  from A will go to B only if A, B, and C <em>all</em> share the

+  <h4><a name="fscroll" id="fscroll">Scrolling Requests</a></h4>
+
+  <p>Fields that are dynamic and have grown and fields explicitly
+  created with offscreen rows are scrollable. One-line fields
+  scroll horizontally; multi-line fields scroll vertically. Most
+  scrolling is triggered by editing and intra-field movement (the
+  library scrolls the field to keep the cursor visible). It is
+  possible to explicitly request scrolling with the following
+  requests:</p>
+
+  <dl>
+    <dt><code>REQ_SCR_FLINE</code>
+    </dt>
+
+    <dd>Scroll vertically forward a line.</dd>

+
+  <h4><a name="fedit" id="fedit">Editing Requests</a></h4>
+
+  <p>When you pass the forms driver an ASCII character, it is
+  treated as a request to add the character to the field's data
+  buffer. Whether this is an insertion or a replacement depends on
+  the field's edit mode (insertion is the default.</p>
+
+  <p>The following requests support editing the field and changing
+  the edit mode:</p>
+
+  <dl>
+    <dt><code>REQ_INS_MODE</code>
+    </dt>
+
+    <dd>Set insertion mode.</dd>
+
+    <dt><code>REQ_OVL_MODE</code>
+    </dt>
+
+    <dd>Set overlay mode.</dd>
+
+    <dt><code>REQ_NEW_LINE</code>
+    </dt>
+
+    <dd>New line request (see below for explanation).</dd>
+
+    <dt><code>REQ_INS_CHAR</code>
+    </dt>
+
+    <dd>Insert space at character location.</dd>
+
+    <dt><code>REQ_INS_LINE</code>
+    </dt>
+
+    <dd>Insert blank line at character location.</dd>
+
+    <dt><code>REQ_DEL_CHAR</code>
+    </dt>
+
+    <dd>Delete character at cursor.</dd>
+
+    <dt><code>REQ_DEL_PREV</code>
+    </dt>

+    </dt>
+
+    <dd>Clear to end of line.</dd>
+
+    <dt><code>REQ_CLR_EOF</code>
+    </dt>
+
+    <dd>Clear to end of field.</dd>
+
+    <dt><code>REQ_CLEAR_FIELD</code>
+    </dt>
+
+    <dd>Clear entire field.</dd>
+  </dl>
+
+  <p>The behavior of the <code>REQ_NEW_LINE</code> and
+  <code>REQ_DEL_PREV</code> requests is complicated and partly
+  controlled by a pair of forms options. The special cases are
+  triggered when the cursor is at the beginning of a field, or on
+  the last line of the field.</p>
+
+  <p>First, we consider <code>REQ_NEW_LINE</code>:</p>
+
+  <p>The normal behavior of <code>REQ_NEW_LINE</code> in insert
+  mode is to break the current line at the position of the edit
+  cursor, inserting the portion of the current line after the
+  cursor as a new line following the current and moving the cursor
+  to the beginning of that new line (you may think of this as
+  inserting a newline in the field buffer).</p>
+
+  <p>The normal behavior of <code>REQ_NEW_LINE</code> in overlay
+  mode is to clear the current line from the position of the edit
+  cursor to end of line. The cursor is then moved to the beginning
+  of the next line.</p>
+
+  <p>However, <code>REQ_NEW_LINE</code> at the beginning of a
+  field, or on the last line of a field, instead does a
+  <code>REQ_NEXT_FIELD</code>. <code>O_NL_OVERLOAD</code> option is
+  off, this special action is disabled.</p>
+
+  <p>Now, let us consider <code>REQ_DEL_PREV</code>:</p>
+
+  <p>The normal behavior of <code>REQ_DEL_PREV</code> is to delete
+  the previous character. If insert mode is on, and the cursor is
+  at the start of a line, and the text on that line will fit on the
+  previous one, it instead appends the contents of the current line
+  to the previous one and deletes the current line (you may think
+  of this as deleting a newline from the field buffer).</p>
+
+  <p>However, <code>REQ_DEL_PREV</code> at the beginning of a field
+  is instead treated as a <code>REQ_PREV_FIELD</code>.</p>
+
+  <p>If the <code>O_BS_OVERLOAD</code> option is off, this special
+  action is disabled and the forms driver just returns
+  <code>E_REQUEST_DENIED</code>.</p>
+
+  <p>See <a href="#frmoptions">Form Options</a> for discussion of
+  how to set and clear the overload options.</p>
+
+  <h4><a name="forder" id="forder">Order Requests</a></h4>
+
+  <p>If the type of your field is ordered, and has associated
+  functions for getting the next and previous values of the type
+  from a given value, there are requests that can fetch that value
+  into the field buffer:</p>
+
+  <dl>
+    <dt><code>REQ_NEXT_CHOICE</code>
+    </dt>
+
+    <dd>Place the successor value of the current value in the
+    buffer.</dd>
+
+    <dt><code>REQ_PREV_CHOICE</code>
+    </dt>
+
+    <dd>Place the predecessor value of the current value in the
+    buffer.</dd>
+  </dl>
+
+  <p>Of the built-in field types, only <code>TYPE_ENUM</code> has
+  built-in successor and predecessor functions. When you define a
+  field type of your own (see <a href="#fcustom">Custom Validation
+  Types</a>), you can associate our own ordering functions.</p>
+
+  <h4><a name="fappcmds" id="fappcmds">Application Commands</a></h4>
+
+  <p>Form requests are represented as integers above the
+  <code>curses</code> value greater than <code>KEY_MAX</code> and
+  less than or equal to the constant <code>MAX_COMMAND</code>. If
+  your input-virtualization routine returns a value above
+  <code>MAX_COMMAND</code>, the forms driver will ignore it.</p>
+
+  <h3><a name="fhooks" id="fhooks">Field Change Hooks</a></h3>
+
+  <p>It is possible to set function hooks to be executed whenever
+  the current field or form changes. Here are the functions that
+  support this:</p>
+
+  <pre class="code-block">
+typedef void    (*HOOK)();       /* pointer to function returning void */
+
+int set_form_init(FORM *form,    /* form to alter */
+                  HOOK hook);    /* initialization hook */
+
+HOOK form_init(FORM *form);      /* form to query */
+
+int set_form_term(FORM *form,    /* form to alter */
+                  HOOK hook);    /* termination hook */
+
+HOOK form_term(FORM *form);      /* form to query */
+
+int set_field_init(FORM *form,   /* form to alter */
+                  HOOK hook);    /* initialization hook */
+
+HOOK field_init(FORM *form);     /* form to query */
+
+int set_field_term(FORM *form,   /* form to alter */
+                  HOOK hook);    /* termination hook */
+
+HOOK field_term(FORM *form);     /* form to query */
+</pre>
+  <p>These functions allow you to either set or query four
+  different hooks. In each of the set functions, the second
+  argument should be the address of a hook function. These
+  functions differ only in the timing of the hook call.</p>
+
+  <dl>
+    <dt>form_init</dt>
+
+    <dd>This hook is called when the form is posted; also, just
+    after each page change operation.</dd>
+
+    <dt>field_init</dt>
+
+    <dd>This hook is called when the form is posted; also, just
+    after each field change</dd>
+
+    <dt>field_term</dt>
+
+    <dd>This hook is called just after field validation; that is,
+    just before the field is altered. It is also called when the
+    form is unposted.</dd>
+
+    <dt>form_term</dt>
+
+    <dd>This hook is called when the form is unposted; also, just
+    before each page change operation.</dd>
+  </dl>
+
+  <p>Calls to these hooks may be triggered</p>
+
+  <ol>
+    <li>When user editing requests are processed by the forms
+    driver</li>
+
+    <li>When the current page is changed by
+    <code>set_current_field()</code> call</li>
+
+    <li>When the current field is changed by a
+    <code>set_form_page()</code> call</li>
+  </ol>
+
+  <p>See <a name="ffocus" id="ffocus">Field Change Commands</a> for
+  discussion of the latter two cases.</p>
+
+  <p>You can set a default hook for all fields by passing one of
+  the set functions a NULL first argument.</p>
+
+  <p>You can disable any of these hooks by (re)setting them to
+  NULL, the default value.</p>
+
+  <h3><a href="#ffocus">Field Change Commands</a></h3>
+
+  <p>Normally, navigation through the form will be driven by the
+  user's input requests. But sometimes it is useful to be able to
+  move the focus for editing and viewing under control of your
+  application, or ask which field it currently is in. The following
+  functions help you accomplish this:</p>
+
+  <pre class="code-block">
+int set_current_field(FORM *form,         /* form to alter */
+                      FIELD *field);      /* field to shift to */
+
+FIELD *current_field(FORM *form);         /* form to query */
+
+int field_index(FORM *form,               /* form to query */
+                FIELD *field);            /* field to get index of */
+</pre>
+  <p>The function <code>field_index()</code> returns the index of
+  the given field in the given form's field array (the array passed
+  to <code>new_form()</code> or
+  <code>set_form_fields()</code>).</p>
+
+  <p>The initial current field of a form is the first active field
+  on the first page. The function <code>set_form_fields()</code>
+  resets this.</p>
+
+  <p>It is also possible to move around by pages.</p>
+
+  <pre class="code-block">
+int set_form_page(FORM *form,             /* form to alter */
+                  int page);              /* page to go to (0-origin) */
+
+int form_page(FORM *form);                /* return form's current page */
+</pre>
+  <p>The initial page of a newly-created form is 0. The function
+  <code>set_form_fields()</code> resets this.</p>
+
+  <h3><a name="frmoptions" id="frmoptions">Form Options</a></h3>
+
+  <p>Like fields, forms may have control option bits. They can be
+  changed or queried with these functions:</p>
+
+  <pre class="code-block">
+int set_form_opts(FORM *form,             /* form to alter */
+                  int attr);              /* attribute to set */
+
+int form_opts_on(FORM *form,              /* form to alter */
+                 int attr);               /* attributes to turn on */
+
+int form_opts_off(FORM *form,             /* form to alter */
+                  int attr);              /* attributes to turn off */
+
+int form_opts(FORM *form);                /* form to query */
+</pre>
+  <p>By default, all options are on. Here are the available option
+  bits:</p>
+
+  <dl>
+    <dt>O_NL_OVERLOAD</dt>
+
+    <dd>Enable overloading of <code>REQ_NEW_LINE</code> as
+    described in <a href="#fedit">Editing Requests</a>. The value
+    of this option is ignored on dynamic fields that have not
+    reached their size limit; these have no last line, so the
+    circumstances for triggering a <code>REQ_NEXT_FIELD</code>
+    never arise.</dd>
+
+    <dt>O_BS_OVERLOAD</dt>
+
+    <dd>Enable overloading of <code>REQ_DEL_PREV</code> as
+    described in <a href="#fedit">Editing Requests</a>.</dd>
+  </dl>
+
+  <p>The option values are bit-masks and can be composed with
+  logical-or in the obvious way.</p>
+
+  <h3><a name="fcustom" id="fcustom">Custom Validation Types</a></h3>
+
+  <p>The <code>form</code> library gives you the capability to
+  define custom validation types of your own. Further, the optional
+  additional arguments of <code>set_field_type</code> effectively
+  allow you to parameterize validation types. Most of the
+  complications in the validation-type interface have to do with
+  the handling of the additional arguments within custom validation
+  functions.</p>
+
+  <h4><a name="flinktypes" id="flinktypes">Union Types</a></h4>
+
+  <p>The simplest way to create a custom data type is to compose it
+  from two preexisting ones:</p>
+
+  <pre class="code-block">
+FIELD *link_fieldtype(FIELDTYPE *type1,
+                      FIELDTYPE *type2);
+</pre>
+  <p>This function creates a field type that will accept any of the
+  values legal for either of its argument field types (which may be
+  either predefined or programmer-defined). If a
+  <code>set_field_type()</code> call later requires arguments, the
+  new composite type expects all arguments for the first type, than
+  all arguments for the second. Order functions (see <a href=
+  "#forder">Order Requests</a>) associated with the component types
+  will work on the composite; what it does is check the validation
+  function for the first type, then for the second, to figure what
+  type the buffer contents should be treated as.</p>
+
+  <h4><a name="fnewtypes" id="fnewtypes">New Field Types</a></h4>
+
+  <p>To create a field type from scratch, you need to specify one
+  or both of the following things:</p>
+
+  <ul>
+    <li>A character-validation function, to check each character as
+    it is entered.</li>
+
+    <li>A field-validation function to be applied on exit from the
+    field.</li>
+  </ul>
+
+  <p>Here is how you do that:</p>
+
+  <pre class="code-block">
+typedef int     (*HOOK)();       /* pointer to function returning int */
+
+FIELDTYPE *new_fieldtype(HOOK f_validate, /* field validator */
+                         HOOK c_validate) /* character validator */
+
+int free_fieldtype(FIELDTYPE *ftype);     /* type to free */
+</pre>
+  <p>At least one of the arguments of <code>new_fieldtype()</code>
+  must be non-NULL. The forms driver will automatically call the
+  new type's validation functions at appropriate points in
+  processing a field of the new type.</p>
+
+  <p>The function <code>free_fieldtype()</code> deallocates the
+  argument fieldtype, freeing all storage associated with it.</p>
+
+  <p>Normally, a field validator is called when the user attempts
+  to leave the field. Its first argument is a field pointer, from
+  which it can get to field buffer 0 and test it. If the function
+  returns TRUE, the operation succeeds; if it returns FALSE, the
+  edit cursor stays in the field.</p>
+
+  <p>A character validator gets the character passed in as a first
+  argument. It too should return TRUE if the character is valid,
+  FALSE otherwise.</p>
+
+  <h4><a name="fcheckargs" id="fcheckargs">Validation Function
+  Arguments</a></h4>
+
+  <p>Your field- and character- validation functions will be passed
+  a second argument as well. This second argument is the address of
+  a structure (which we will call a <em>pile</em>) built from any
+  of the field-type-specific arguments passed to
+  <code>set_field_type()</code>. If no such arguments are defined
+  for the field type, this pile pointer argument will be NULL.</p>
+
+  <p>In order to arrange for such arguments to be passed to your
+  validation functions, you must associate a small set of
+  storage-management functions with the type. The forms driver will
+  use these to synthesize a pile from the trailing arguments of
+  each <code>set_field_type()</code> argument, and a pointer to the
+  pile will be passed to the validation functions.</p>
+
+  <p>Here is how you make the association:</p>
+
+  <pre class="code-block">
+typedef char    *(*PTRHOOK)();    /* pointer to function returning (char *) */
+typedef void    (*VOIDHOOK)();    /* pointer to function returning void */
+
+int set_fieldtype_arg(FIELDTYPE *type,    /* type to alter */
+                      PTRHOOK make_str,   /* make structure from args */
+                      PTRHOOK copy_str,   /* make copy of structure */
+                      VOIDHOOK free_str); /* free structure storage */
+</pre>
+  <p>Here is how the storage-management hooks are used:</p>
+
+  <dl>
+    <dt><code>make_str</code>
+    </dt>
+
+    <dd>This function is called by <code>set_field_type()</code>.
+    It gets one argument, a <code>va_list</code> of the
+    type-specific arguments passed to
+    <code>set_field_type()</code>. It is expected to return a pile
+    pointer to a data structure that encapsulates those
+    arguments.</dd>
+
+    <dt><code>copy_str</code>
+    </dt>
+
+    <dd>This function is called by form library functions that
+    allocate new field instances. It is expected to take a pile
+    pointer, copy the pile to allocated storage, and return the
+    address of the pile copy.</dd>
+
+    <dt><code>free_str</code>
+    </dt>
+
+    <dd>This function is called by field- and type-deallocation
+    routines in the library. It takes a pile pointer argument, and
+    is expected to free the storage of that pile.</dd>
+  </dl>
+
+  <p>The <code>make_str</code> and <code>copy_str</code> functions
+  may return NULL to signal allocation failure. The library
+  routines will that call them will return error indication when
+  this happens. Thus, your validation functions should never see a
+  NULL file pointer and need not check specially for it.</p>
+
+  <h4><a name="fcustorder" id="fcustorder">Order Functions For
+  Custom Types</a></h4>
+
+  <p>Some custom field types are simply ordered in the same
+  well-defined way that <code>TYPE_ENUM</code> is. For such types,
+  it is possible to define successor and predecessor functions to
+  support the <code>REQ_NEXT_CHOICE</code> and
+  <code>REQ_PREV_CHOICE</code> requests. Here is how:</p>
+
+  <pre class="code-block">
+typedef int     (*INTHOOK)();     /* pointer to function returning int */
+
+int set_fieldtype_arg(FIELDTYPE *type,    /* type to alter */
+                      INTHOOK succ,       /* get successor value */
+                      INTHOOK pred);      /* get predecessor value */
+</pre>
+  <p>The successor and predecessor arguments will each be passed
+  two arguments; a field pointer, and a pile pointer (as for the
+  validation functions). They are expected to use the function
+  <code>field_buffer()</code> to read the current value, and
+  <code>set_field_buffer()</code> on buffer 0 to set the next or
+  previous value. Either hook may return TRUE to indicate success
+  (a legal next or previous value was set) or FALSE to indicate
+  failure.</p>
+
+  <h4><a name="fcustprobs" id="fcustprobs">Avoiding Problems</a></h4>
+
+  <p>The interface for defining custom types is complicated and
+  tricky. Rather than attempting to create a custom type entirely
+  from scratch, you should start by studying the library source
+  code for whichever of the pre-defined types seems to be closest
+  to what you want.</p>
+
+  <p>Use that code as a model, and evolve it towards what you
+  really want. You will avoid many problems and annoyances that
+  way. The code in the <code>ncurses</code> library has been
+  specifically exempted from the package copyright to support
+  this.</p>
+
+  <p>If your custom type defines order functions, have do something
+  intuitive with a blank field. A useful convention is to make the
+  successor of a blank field the types minimum value, and its
+  predecessor the maximum.</p>

+Introduction
+
+   This document is an introduction to programming with curses. It is not
+   an   exhaustive  reference  for  the  curses  Application  Programming
+   Interface  (API);  that  role  is  filled  by the curses manual pages.
+   Rather,  it  is  intended  to  help  C programmers ease into using the
+   package.
+
+   This   document  is  aimed  at  C  applications  programmers  not  yet
+   specifically  familiar with ncurses. If you are already an experienced
+   curses  programmer, you should nevertheless read the sections on Mouse
+   Interfacing,  Debugging, Compatibility with Older Versions, and Hints,
+   Tips,  and  Tricks.  These  will  bring you up to speed on the special
+   features  and  quirks of the ncurses implementation. If you are not so
+   experienced, keep reading.
+
+   The  curses  package  is a subroutine library for terminal-independent
+   screen-painting  and  input-event handling which presents a high level
+   screen  model  to  the programmer, hiding differences between terminal
+   types  and doing automatic optimization of output to change one screen
+   full  of  text into another. Curses uses terminfo, which is a database
+   format  that  can  describe the capabilities of thousands of different
+   terminals.
+
+   The  curses  API  may  seem  something of an archaism on UNIX desktops
+   increasingly  dominated  by  X,  Motif, and Tcl/Tk. Nevertheless, UNIX
+   still  supports  tty lines and X supports xterm(1); the curses API has
+   the advantage of (a) back-portability to character-cell terminals, and
+   (b)  simplicity.  For  an application that does not require bit-mapped
+   graphics  and multiple fonts, an interface implementation using curses
+   will  typically  be  a  great deal simpler and less expensive than one
+   using an X toolkit.
+
+  A Brief History of Curses
+
+   Historically, the first ancestor of curses was the routines written to
+   provide  screen-handling  for  the  vi  editor; these used the termcap
+   database  facility  (both  released  in  3BSD) for describing terminal
+   capabilities. These routines were abstracted into a documented library
+   and  first released with the early BSD UNIX versions. All of this work
+   was  done  by  students  at  the  University  of  California (Berkeley
+   campus).  The  curses  library  was  first published in 4.0BSD, a year
+   after 3BSD (i.e., late 1980).
+
+   After  graduation,  one  of  those  students went to work at AT&T Bell
+   Labs,  and  made  an  improved  termcap library called terminfo (i.e.,
+   "libterm"),  and  adapted  the  curses  library  to use this. That was
+   subsequently  released in System V Release 2 (early 1984). Thereafter,
+   other  developers  added  to  the  curses  and terminfo libraries. For
+   instance,  a  student at Cornell University wrote an improved terminfo
+   library  as well as a tool (tic) to compile the terminal descriptions.
+   As  a  general  rule,  AT&T  did  not  identify  the developers in the
+   source-code  or  documentation;  the  tic and infocmp programs are the
+   exceptions.
+
+   System  V  Release  3  (System  III  UNIX)  from  Bell Labs featured a
+   rewritten and much-improved curses library, along with the tic program
+   (late 1986).
+
+   To  recap,  terminfo  is  based  on  Berkeley's  termcap database, but
+   contains  a  number  of  improvements  and  extensions.  Parameterized
+   capabilities  strings  were introduced, making it possible to describe
+   multiple  video  attributes, and colors and to handle far more unusual
+   terminals  than  possible  with  termcap.  In  the later AT&T System V
+   releases,  curses  evolved  to  use  more  facilities  and  offer more
+   capabilities, going far beyond BSD curses in power and flexibility.
+
+  Scope of This Document
+
+   This document describes ncurses, a free implementation of the System V
+   curses  API  with  some  clearly  marked  extensions.  It includes the
+   following System V curses features:
+     * Support  for  multiple  screen  highlights  (BSD curses could only
+       handle one "standout" highlight, usually reverse-video).
+     * Support for line- and box-drawing using forms characters.
+     * Recognition of function keys on input.
+     * Color support.
+     * Support  for pads (windows of larger than screen size on which the
+       screen or a subwindow defines a viewport).
+
+   Also,  this  package  makes  use  of  the  insert  and delete line and
+   character  features  of  terminals  so equipped, and determines how to
+   optimally  use  these  features  with  no help from the programmer. It
+   allows  arbitrary  combinations  of  video attributes to be displayed,
+   even  on  terminals  that  leave "magic cookies" on the screen to mark
+   changes in attributes.
+
+   The  ncurses  package  can  also  capture and use event reports from a
+   mouse in some environments (notably, xterm under the X window system).
+   This document includes tips for using the mouse.
+
+   The  ncurses  package  was  originated  by  Pavel Curtis. The original
+   maintainer  of  this  package is Zeyd Ben-Halim <zmbenhal@netcom.com>.
+   Eric S. Raymond <esr@snark.thyrsus.com> wrote many of the new features
+   in  versions  after 1.8.1 and wrote most of this introduction. Juergen
+   Pfeifer  wrote  all  of  the  menu and forms code as well as the Ada95
+   binding.  Ongoing  work  is  being done by Thomas Dickey (maintainer).
+   Contact the current maintainers at bug-ncurses@gnu.org.
+
+   This  document  also describes the panels extension library, similarly
+   modeled  on  the  SVr4  panels  facility.  This  library allows you to
+   associate  backing  store  with each of a stack or deck of overlapping
+   windows,  and  provides  operations  for  moving windows around in the
+   stack that change their visibility in the natural way (handling window
+   overlaps).
+
+   Finally,  this  document  describes  in  detail  the  menus  and forms
+   extension  libraries,  also  cloned  from System V, which support easy
+   construction and sequences of menus and fill-in forms.
+
+  Terminology
+
+   In  this  document,  the following terminology is used with reasonable
+   consistency:
+
+   window
+          A  data  structure  describing  a  sub-rectangle  of the screen
+          (possibly  the  entire  screen).  You  can write to a window as
+          though  it  were a miniature screen, scrolling independently of
+          other windows on the physical screen.
+
+   screens
+          A  subset of windows which are as large as the terminal screen,
+          i.e.,  they  start  at the upper left hand corner and encompass
+          the   lower  right  hand  corner.  One  of  these,  stdscr,  is
+          automatically provided for the programmer.
+
+   terminal screen
+          The package's idea of what the terminal display currently looks
+          like, i.e., what the user sees now. This is a special screen.
+
+The Curses Library
+
+  An Overview of Curses
+
+    Compiling Programs using Curses
+
+   In order to use the library, it is necessary to have certain types and
+   variables defined. Therefore, the programmer must have a line:
+          #include <curses.h>
+
+   at the top of the program source. The screen package uses the Standard
+   I/O   library,  so  <curses.h>  includes  <stdio.h>.  <curses.h>  also
+   includes  <termios.h>,  <termio.h>,  or  <sgtty.h>  depending  on your
+   system.  It is redundant (but harmless) for the programmer to do these
+   includes,  too.  In  linking with curses you need to have -lncurses in
+   your  LDFLAGS  or  on the command line. There is no need for any other
+   libraries.
+
+    Updating the Screen
+
+   In  order  to  update  the  screen  optimally, it is necessary for the
+   routines  to  know  what  the screen currently looks like and what the
+   programmer  wants  it to look like next. For this purpose, a data type
+   (structure)  named WINDOW is defined which describes a window image to
+   the  routines,  including its starting position on the screen (the (y,
+   x)  coordinates  of  the  upper left hand corner) and its size. One of
+   these  (called  curscr,  for current screen) is a screen image of what
+   the  terminal currently looks like. Another screen (called stdscr, for
+   standard screen) is provided by default to make changes on.
+
+   A  window is a purely internal representation. It is used to build and
+   store a potential image of a portion of the terminal. It does not bear
+   any necessary relation to what is really on the terminal screen; it is
+   more like a scratchpad or write buffer.
+
+   To  make  the  section  of  physical  screen corresponding to a window
+   reflect  the  contents  of the window structure, the routine refresh()
+   (or wrefresh() if the window is not stdscr) is called.
+
+   A  given physical screen section may be within the scope of any number
+   of  overlapping  windows.  Also, changes can be made to windows in any
+   order,  without  regard  to  motion  efficiency.  Then,  at  will, the
+   programmer  can  effectively say "make it look like this," and let the
+   package implementation determine the most efficient way to repaint the
+   screen.
+
+    Standard Windows and Function Naming Conventions
+
+   As  hinted  above,  the  routines can use several windows, but two are
+   automatically given: curscr, which knows what the terminal looks like,
+   and  stdscr,  which  is what the programmer wants the terminal to look
+   like  next.  The  user  should  never actually access curscr directly.
+   Changes  should  be  made  to  through  the  API, and then the routine
+   refresh() (or wrefresh()) called.
+
+   Many  functions  are  defined  to  use stdscr as a default screen. For
+   example,  to  add  a  character  to stdscr, one calls addch() with the
+   desired character as argument. To write to a different window. use the
+   routine  waddch()  (for  window-specific  addch())  is  provided. This
+   convention of prepending function names with a "w" when they are to be
+   applied  to specific windows is consistent. The only routines which do
+   not follow it are those for which a window must always be specified.
+
+   In  order  to  move  the  current (y, x) coordinates from one point to
+   another,  the routines move() and wmove() are provided. However, it is
+   often  desirable to first move and then perform some I/O operation. In
+   order  to  avoid  clumsiness, most I/O routines can be preceded by the
+   prefix  "mv"  and  the  desired  (y,  x)  coordinates prepended to the
+   arguments to the function. For example, the calls
+          move(y, x);
+          addch(ch);
+
+   can be replaced by
+          mvaddch(y, x, ch);
+
+   and
+          wmove(win, y, x);
+          waddch(win, ch);
+
+   can be replaced by
+          mvwaddch(win, y, x, ch);
+
+   Note  that the window description pointer (win) comes before the added
+   (y,  x)  coordinates.  If  a function requires a window pointer, it is
+   always the first parameter passed.
+
+    Variables
+
+   The  curses  library  sets  some  variables  describing  the  terminal
+   capabilities.
+      type   name      description
+      ------------------------------------------------------------------
+      int    LINES     number of lines on the terminal
+      int    COLS      number of columns on the terminal
+
+   The  curses.h  also  introduces  some  #define  constants and types of
+   general usefulness:
+
+   bool
+          boolean type, actually a "char" (e.g., bool doneit;)
+
+   TRUE
+          boolean "true" flag (1).
+
+   FALSE
+          boolean "false" flag (0).
+
+   ERR
+          error flag returned by routines on a failure (-1).
+
+   OK
+          error flag returned by routines when things go right.
+
+  Using the Library
+
+   Now  we  describe  how  to  actually use the screen package. In it, we
+   assume  all  updating,  reading,  etc.  is  applied  to  stdscr. These
+   instructions  will  work  on  any  window,  providing  you  change the
+   function names and parameters as mentioned above.
+
+   Here is a sample program to motivate the discussion:
+#include <stdlib.h>
+#include <curses.h>
+#include <signal.h>
+
+static void finish(int sig);
+
+int
+main(int argc, char *argv[])
+{
+    int num = 0;
+
+    /* initialize your non-curses data structures here */
+
+    (void) signal(SIGINT, finish);      /* arrange interrupts to terminate */
+
+    (void) initscr();      /* initialize the curses library */
+    keypad(stdscr, TRUE);  /* enable keyboard mapping */
+    (void) nonl();         /* tell curses not to do NL->CR/NL on output */
+    (void) cbreak();       /* take input chars one at a time, no wait for \n */
+    (void) echo();         /* echo input - in color */
+
+    if (has_colors())
+    {
+        start_color();
+
+        /*
+         * Simple color assignment, often all we need.  Color pair 0 cannot
+         * be redefined.  This example uses the same value for the color
+         * pair as for the foreground color, though of course that is not
+         * necessary:
+         */
+        init_pair(1, COLOR_RED,     COLOR_BLACK);
+        init_pair(2, COLOR_GREEN,   COLOR_BLACK);
+        init_pair(3, COLOR_YELLOW,  COLOR_BLACK);
+        init_pair(4, COLOR_BLUE,    COLOR_BLACK);
+        init_pair(5, COLOR_CYAN,    COLOR_BLACK);
+        init_pair(6, COLOR_MAGENTA, COLOR_BLACK);
+        init_pair(7, COLOR_WHITE,   COLOR_BLACK);
+    }
+
+    for (;;)
+    {
+        int c = getch();     /* refresh, accept single keystroke of input */
+        attrset(COLOR_PAIR(num % 8));
+        num++;
+
+        /* process the command keystroke */
+    }
+
+    finish(0);               /* we are done */
+}
+
+static void finish(int sig)
+{
+    endwin();
+
+    /* do your non-curses wrapup here */
+
+    exit(0);
+}
+
+    Starting up
+
+   In  order  to  use  the  screen  package, the routines must know about
+   terminal  characteristics, and the space for curscr and stdscr must be
+   allocated.  These  function initscr() does both these things. Since it
+   must  allocate  space  for  the  windows,  it can overflow memory when
+   attempting  to  do  so.  On the rare occasions this happens, initscr()
+   will  terminate  the  program  with  an  error message. initscr() must
+   always  be  called before any of the routines which affect windows are
+   used.  If  it  is  not,  the  program will core dump as soon as either
+   curscr  or  stdscr are referenced. However, it is usually best to wait
+   to  call  it  until  after  you  are sure you will need it, like after
+   checking  for  startup  errors. Terminal status changing routines like
+   nl() and cbreak() should be called after initscr().
+
+   Once  the  screen windows have been allocated, you can set them up for
+   your  program.  If  you  want  to,  say, allow a screen to scroll, use
+   scrollok().  If you want the cursor to be left in place after the last
+   change,  use  leaveok().  If this is not done, refresh() will move the
+   cursor to the window's current (y, x) coordinates after updating it.
+
+   You  can  create new windows of your own using the functions newwin(),
+   derwin(), and subwin(). The routine delwin() will allow you to get rid
+   of  old windows. All the options described above can be applied to any
+   window.
+
+    Output
+
+   Now  that  we  have set things up, we will want to actually update the
+   terminal.  The basic functions used to change what will go on a window
+   are addch() and move(). addch() adds a character at the current (y, x)
+   coordinates. move() changes the current (y, x) coordinates to whatever
+   you want them to be. It returns ERR if you try to move off the window.
+   As  mentioned above, you can combine the two into mvaddch() to do both
+   things at once.
+
+   The  other  output  functions, such as addstr() and printw(), all call
+   addch() to add characters to the window.
+
+   After  you  have  put on the window what you want there, when you want
+   the  portion  of the terminal covered by the window to be made to look
+   like  it,  you  must  call  refresh().  In  order  to optimize finding
+   changes,  refresh()  assumes  that  any part of the window not changed
+   since  the  last  refresh() of that window has not been changed on the
+   terminal,  i.e., that you have not refreshed a portion of the terminal
+   with  an  overlapping  window.  If  this  is not the case, the routine
+   touchwin() is provided to make it look like the entire window has been
+   changed,  thus  making  refresh()  check  the  whole subsection of the
+   terminal for changes.
+
+   If  you  call wrefresh() with curscr as its argument, it will make the
+   screen  look  like  curscr  thinks  it  looks like. This is useful for
+   implementing  a  command  which would redraw the screen in case it get
+   messed up.
+
+    Input
+
+   The  complementary  function  to  addch() is getch() which, if echo is
+   set, will call addch() to echo the character. Since the screen package
+   needs  to know what is on the terminal at all times, if characters are
+   to  be  echoed, the tty must be in raw or cbreak mode. Since initially
+   the terminal has echoing enabled and is in ordinary "cooked" mode, one
+   or  the  other  has  to changed before calling getch(); otherwise, the
+   program's output will be unpredictable.
+
+   When you need to accept line-oriented input in a window, the functions
+   wgetstr() and friends are available. There is even a wscanw() function
+   that  can  do  scanf()(3)-style  multi-field  parsing on window input.
+   These  pseudo-line-oriented  functions  turn  on  echoing  while  they
+   execute.
+
+   The  example  code  above uses the call keypad(stdscr, TRUE) to enable
+   support  for function-key mapping. With this feature, the getch() code
+   watches  the  input  stream for character sequences that correspond to
+   arrow   and   function   keys.   These   sequences   are  returned  as
+   pseudo-character values. The #define values returned are listed in the
+   curses.h The mapping from sequences to #define values is determined by
+   key_ capabilities in the terminal's terminfo entry.
+
+    Using Forms Characters
+
+   The  addch()  function (and some others, including box() and border())
+   can accept some pseudo-character arguments which are specially defined
+   by  ncurses.  These  are #define values set up in the curses.h header;
+   see there for a complete list (look for the prefix ACS_).
+
+   The  most  useful of the ACS defines are the forms-drawing characters.
+   You  can  use  these to draw boxes and simple graphs on the screen. If
+   the  terminal does not have such characters, curses.h will map them to
+   a recognizable (though ugly) set of ASCII defaults.
+
+    Character Attributes and Color
+
+   The  ncurses  package  supports  screen highlights including standout,
+   reverse-video,  underline, and blink. It also supports color, which is
+   treated as another kind of highlight.
+
+   Highlights   are   encoded,   internally,   as   high   bits   of  the
+   pseudo-character  type  (chtype)  that  curses.h uses to represent the
+   contents of a screen cell. See the curses.h header file for a complete
+   list of highlight mask values (look for the prefix A_).
+
+   There  are two ways to make highlights. One is to logical-or the value
+   of  the  highlights you want into the character argument of an addch()
+   call, or any other output call that takes a chtype argument.
+
+   The  other is to set the current-highlight value. This is logical-ORed
+   with  any  highlight  you  specify the first way. You do this with the
+   functions attron(), attroff(), and attrset(); see the manual pages for
+   details.  Color  is  a special kind of highlight. The package actually
+   thinks  in  terms  of  color  pairs,  combinations  of  foreground and
+   background  colors.  The  sample code above sets up eight color pairs,
+   all  of the guaranteed-available colors on black. Note that each color
+   pair  is, in effect, given the name of its foreground color. Any other
+   range  of  eight  non-conflicting  values  could have been used as the
+   first arguments of the init_pair() values.
+
+   Once  you  have done an init_pair() that creates color-pair N, you can
+   use  COLOR_PAIR(N)  as  a highlight that invokes that particular color
+   combination.  Note  that  COLOR_PAIR(N),  for  constant N, is itself a
+   compile-time constant and can be used in initializers.
+
+    Mouse Interfacing
+
+   The ncurses library also provides a mouse interface.
+
+     NOTE:  this  facility  is  specific  to  ncurses, it is not part of
+     either  the XSI Curses standard, nor of System V Release 4, nor BSD
+     curses.  System  V  Release  4  curses  contains  code with similar
+     interface  definitions, however it is not documented. Other than by
+     disassembling  the library, we have no way to determine exactly how
+     that   mouse   code   works.  Thus,  we  recommend  that  you  wrap
+     mouse-related   code   in   an   #ifdef  using  the  feature  macro
+     NCURSES_MOUSE_VERSION  so  it  will  not  be compiled and linked on
+     non-ncurses systems.
+
+   Presently, mouse event reporting works in the following environments:
+     * xterm and similar programs such as rxvt.
+     * Linux  console,  when  configured with gpm(1), Alessandro Rubini's
+       mouse server.
+     * FreeBSD sysmouse (console)
+     * OS/2 EMX
+
+   The  mouse  interface  is  very  simple.  To  activate it, you use the
+   function  mousemask(),  passing  it  as first argument a bit-mask that
+   specifies  what  kinds  of  events you want your program to be able to
+   see.  It  will  return  the  bit-mask  of  events that actually become
+   visible, which may differ from the argument if the mouse device is not
+   capable of reporting some of the event types you specify.
+
+   Once the mouse is active, your application's command loop should watch
+   for  a  return  value of KEY_MOUSE from wgetch(). When you see this, a
+   mouse  event report has been queued. To pick it off the queue, use the
+   function  getmouse()  (you  must  do  this  before  the next wgetch(),
+   otherwise  another  mouse  event  might come in and make the first one
+   inaccessible).
+
+   Each  call  to  getmouse() fills a structure (the address of which you
+   will  pass  it)  with  mouse  event  data.  The  event  data  includes
+   zero-origin,  screen-relative  character-cell coordinates of the mouse
+   pointer.  It  also  includes  an event mask. Bits in this mask will be
+   set, corresponding to the event type being reported.
+
+   The  mouse  structure  contains  two  additional  fields  which may be
+   significant  in  the  future  as  ncurses  interfaces  to new kinds of
+   pointing  device.  In addition to x and y coordinates, there is a slot
+   for  a  z coordinate; this might be useful with touch-screens that can
+   return  a  pressure  or  duration parameter. There is also a device ID
+   field,  which  could  be used to distinguish between multiple pointing
+   devices.
+
+   The   class  of  visible  events  may  be  changed  at  any  time  via
+   mousemask().  Events  that  can be reported include presses, releases,
+   single-,   double-   and   triple-clicks  (you  can  set  the  maximum
+   button-down  time for clicks). If you do not make clicks visible, they
+   will  be  reported  as  press-release pairs. In some environments, the
+   event  mask  may  include  bits reporting the state of shift, alt, and
+   ctrl keys on the keyboard during the event.
+
+   A  function  to check whether a mouse event fell within a given window
+   is  also  supplied.  You  can  use  this to see whether a given window
+   should consider a mouse event relevant to it.
+
+   Because   mouse   event   reporting  will  not  be  available  in  all
+   environments,  it  would  be unwise to build ncurses applications that
+   require  the  use  of  a  mouse. Rather, you should use the mouse as a
+   shortcut  for point-and-shoot commands your application would normally
+   accept  from  the  keyboard.  Two  of  the  test  games in the ncurses
+   distribution  (bs  and  knight) contain code that illustrates how this
+   can be done.
+
+   See   the   manual   page  curs_mouse(3X)  for  full  details  of  the
+   mouse-interface functions.
+
+    Finishing Up
+
+   In  order to clean up after the ncurses routines, the routine endwin()
+   is  provided.  It  restores tty modes to what they were when initscr()
+   was  first called, and moves the cursor down to the lower-left corner.
+   Thus,  anytime  after  the  call to initscr, endwin() should be called
+   before exiting.
+
+  Function Descriptions
+
+   We  describe  the detailed behavior of some important curses functions
+   here, as a supplement to the manual page descriptions.
+
+    Initialization and Wrapup
+
+   initscr()
+          The  first  function  called should almost always be initscr().
+          This  will  determine  the  terminal type and initialize curses
+          data structures. initscr() also arranges that the first call to
+          refresh()  will  clear the screen. If an error occurs a message
+          is  written  to standard error and the program exits. Otherwise
+          it  returns  a pointer to stdscr. A few functions may be called
+          before  initscr (slk_init(), filter(), ripoffline(), use_env(),
+          and, if you are using multiple terminals, newterm().)
+
+   endwin()
+          Your  program  should  always  call  endwin() before exiting or
+          shelling  out  of  the  program. This function will restore tty
+          modes,  move the cursor to the lower left corner of the screen,
+          reset  the  terminal  into  the proper non-visual mode. Calling
+          refresh()  or  doupdate()  after  a  temporary  escape from the
+          program will restore the ncurses screen from before the escape.
+
+   newterm(type, ofp, ifp)
+          A  program  which  outputs to more than one terminal should use
+          newterm() instead of initscr(). newterm() should be called once
+          for each terminal. It returns a variable of type SCREEN * which
+          should  be  saved  as  a  reference  to that terminal. (NOTE: a
+          SCREEN  variable is not a screen in the sense we are describing
+          in  this  introduction,  but a collection of parameters used to
+          assist  in  optimizing the display.) The arguments are the type
+          of the terminal (a string) and FILE pointers for the output and
+          input  of  the  terminal.  If type is NULL then the environment
+          variable  $TERM  is used. endwin() should called once at wrapup
+          time for each terminal opened using this function.
+
+   set_term(new)
+          This  function  is  used  to  switch  to  a  different terminal
+          previously  opened  by  newterm(). The screen reference for the
+          new  terminal is passed as the parameter. The previous terminal
+          is  returned  by  the function. All other calls affect only the
+          current terminal.
+
+   delscreen(sp)
+          The  inverse  of  newterm();  deallocates  the  data structures
+          associated with a given SCREEN reference.
+
+    Causing Output to the Terminal
+
+   refresh() and wrefresh(win)
+          These  functions  must  be called to actually get any output on
+          the   terminal,   as  other  routines  merely  manipulate  data
+          structures.  wrefresh() copies the named window to the physical
+          terminal  screen,  taking into account what is already there in
+          order  to do optimizations. refresh() does a refresh of stdscr.
+          Unless  leaveok()  has been enabled, the physical cursor of the
+          terminal is left at the location of the window's cursor.
+
+   doupdate() and wnoutrefresh(win)
+          These two functions allow multiple updates with more efficiency
+          than  wrefresh.  To use them, it is important to understand how
+          curses  works. In addition to all the window structures, curses
+          keeps  two  data structures representing the terminal screen: a
+          physical screen, describing what is actually on the screen, and
+          a  virtual screen, describing what the programmer wants to have
+          on the screen. wrefresh works by first copying the named window
+          to  the  virtual  screen (wnoutrefresh()), and then calling the
+          routine  to  update  the screen (doupdate()). If the programmer
+          wishes  to output several windows at once, a series of calls to
+          wrefresh will result in alternating calls to wnoutrefresh() and
+          doupdate(),  causing several bursts of output to the screen. By
+          calling  wnoutrefresh() for each window, it is then possible to
+          call  doupdate()  once,  resulting in only one burst of output,
+          with  fewer  total  characters  transmitted (this also avoids a
+          visually annoying flicker at each update).
+
+    Low-Level Capability Access
+
+   setupterm(term, filenum, errret)
+          This  routine is called to initialize a terminal's description,
+          without setting up the curses screen structures or changing the
+          tty-driver mode bits. term is the character string representing
+          the  name  of the terminal being used. filenum is the UNIX file
+          descriptor  of  the terminal to be used for output. errret is a
+          pointer to an integer, in which a success or failure indication
+          is  returned. The values returned can be 1 (all is well), 0 (no
+          such  terminal),  or  -1  (some  problem  locating the terminfo
+          database).
+
+          The  value  of  term can be given as NULL, which will cause the
+          value of TERM in the environment to be used. The errret pointer
+          can  also be given as NULL, meaning no error code is wanted. If
+          errret is defaulted, and something goes wrong, setupterm() will
+          print  an  appropriate  error  message  and  exit,  rather than
+          returning.  Thus,  a simple program can call setupterm(0, 1, 0)
+          and not worry about initialization errors.
+
+          After  the call to setupterm(), the global variable cur_term is
+          set to point to the current structure of terminal capabilities.
+          By  calling  setupterm()  for  each  terminal,  and  saving and
+          restoring  cur_term, it is possible for a program to use two or
+          more  terminals  at  once.  Setupterm()  also  stores the names
+          section  of  the  terminal  description in the global character
+          array ttytype[]. Subsequent calls to setupterm() will overwrite
+          this array, so you will have to save it yourself if need be.
+
+    Debugging
+
+     NOTE: These functions are not part of the standard curses API!
+
+   trace()
+          This  function  can be used to explicitly set a trace level. If
+          the  trace  level  is  nonzero,  execution of your program will
+          generate a file called "trace" in the current working directory
+          containing  a  report  on  the  library's actions. Higher trace
+          levels  enable  more  detailed  (and  verbose) reporting -- see
+          comments  attached  to  TRACE_ defines in the curses.h file for
+          details. (It is also possible to set a trace level by assigning
+          a trace level value to the environment variable NCURSES_TRACE).
+
+   _tracef()
+          This  function  can  be  used  to  output  your  own  debugging
+          information.  It  is  only  available  only  if  you  link with
+          -lncurses_g.  It  can be used the same way as printf(), only it
+          outputs  a  newline after the end of arguments. The output goes
+          to a file called trace in the current directory.
+
+   Trace  logs  can  be difficult to interpret due to the sheer volume of
+   data dumped in them. There is a script called tracemunch included with
+   the  ncurses distribution that can alleviate this problem somewhat; it
+   compacts  long  sequences  of  similar  operations  into more succinct
+   single-line  pseudo-operations.  These pseudo-ops can be distinguished
+   by the fact that they are named in capital letters.
+
+  Hints, Tips, and Tricks
+
+   The ncurses manual pages are a complete reference for this library. In
+   the remainder of this document, we discuss various useful methods that
+   may not be obvious from the manual page descriptions.
+
+    Some Notes of Caution
+
+   If  you  find yourself thinking you need to use noraw() or nocbreak(),
+   think  again  and  move carefully. It is probably better design to use
+   getstr()  or one of its relatives to simulate cooked mode. The noraw()
+   and  nocbreak() functions try to restore cooked mode, but they may end
+   up   clobbering   some  control  bits  set  before  you  started  your
+   application.  Also,  they  have always been poorly documented, and are
+   likely   to  hurt  your  application's  usability  with  other  curses
+   libraries.
+
+   Bear  in mind that refresh() is a synonym for wrefresh(stdscr). Do not
+   try  to  mix use of stdscr with use of windows declared by newwin(); a
+   refresh()  call will blow them off the screen. The right way to handle
+   this  is  to  use  subwin(),  or not touch stdscr at all and tile your
+   screen  with  declared windows which you then wnoutrefresh() somewhere
+   in  your  program event loop, with a single doupdate() call to trigger
+   actual repainting.
+
+   You  are  much  less  likely  to  run into problems if you design your
+   screen   layouts   to  use  tiled  rather  than  overlapping  windows.
+   Historically,  curses  support  for overlapping windows has been weak,
+   fragile,  and  poorly  documented.  The  ncurses library is not yet an
+   exception to this rule.
+
+   There  is  a  panels library included in the ncurses distribution that
+   does  a  pretty  good  job  of  strengthening  the overlapping-windows
+   facilities.
+
+   Try to avoid using the global variables LINES and COLS. Use getmaxyx()
+   on  the stdscr context instead. Reason: your code may be ported to run
+   in  an  environment with window resizes, in which case several screens
+   could be open with different sizes.
+
+    Temporarily Leaving NCURSES Mode
+
+   Sometimes  you  will  want  to write a program that spends most of its
+   time  in  screen  mode,  but occasionally returns to ordinary "cooked"
+   mode.  A common reason for this is to support shell-out. This behavior
+   is simple to arrange in ncurses.
+
+   To  leave  ncurses  mode,  call  endwin()  as  you  would  if you were
+   intending  to terminate the program. This will take the screen back to
+   cooked  mode;  you  can  do your shell-out. When you want to return to
+   ncurses  mode,  simply call refresh() or doupdate(). This will repaint
+   the screen.
+
+   There  is  a  boolean function, isendwin(), which code can use to test
+   whether ncurses screen mode is active. It returns TRUE in the interval
+   between an endwin() call and the following refresh(), FALSE otherwise.
+
+   Here is some sample code for shellout:
+    addstr("Shelling out...");
+    def_prog_mode();           /* save current tty modes */
+    endwin();                  /* restore original tty modes */
+    system("sh");              /* run shell */
+    addstr("returned.\n");     /* prepare return message */
+    refresh();                 /* restore save modes, repaint screen */
+
+    Using NCURSES under XTERM
+
+   A  resize  operation  in  X  sends SIGWINCH to the application running
+   under  xterm.  The  easiest way to handle SIGWINCH is to do an endwin,
+   followed  by  an  refresh  and a screen repaint you code yourself. The
+   refresh will pick up the new screen size from the xterm's environment.
+
+   That  is the standard way, of course (it even works with some vendor's
+   curses  implementations). Its drawback is that it clears the screen to
+   reinitialize the display, and does not resize subwindows which must be
+   shrunk.   Ncurses  provides  an  extension  which  works  better,  the
+   resizeterm  function.  That  function  ensures  that  all  windows are
+   limited  to  the new screen dimensions, and pads stdscr with blanks if
+   the screen is larger.
+
+   The ncurses library provides a SIGWINCH signal handler, which pushes a
+   KEY_RESIZE  via the wgetch() calls. When ncurses returns that code, it
+   calls  resizeterm  to update the size of the standard screen's window,
+   repainting that (filling with blanks or truncating as needed). It also
+   resizes other windows, but its effect may be less satisfactory because
+   it  cannot  know  how you want the screen re-painted. You will usually
+   have to write special-purpose code to handle KEY_RESIZE yourself.
+
+    Handling Multiple Terminal Screens
+
+   The initscr() function actually calls a function named newterm() to do
+   most  of  its  work.  If you are writing a program that opens multiple
+   terminals, use newterm() directly.
+
+   For  each call, you will have to specify a terminal type and a pair of
+   file  pointers;  each  call will return a screen reference, and stdscr
+   will be set to the last one allocated. You will switch between screens
+   with  the  set_term  call.  Note  that  you  will  also  have  to call
+   def_shell_mode and def_prog_mode on each tty yourself.
+
+    Testing for Terminal Capabilities
+
+   Sometimes you may want to write programs that test for the presence of
+   various  capabilities before deciding whether to go into ncurses mode.
+   An  easy way to do this is to call setupterm(), then use the functions
+   tigetflag(), tigetnum(), and tigetstr() to do your testing.
+
+   A  particularly  useful  case  of this often comes up when you want to
+   test  whether  a  given  terminal  type  should  be treated as "smart"
+   (cursor-addressable) or "stupid". The right way to test this is to see
+   if the return value of tigetstr("cup") is non-NULL. Alternatively, you
+   can  include  the  term.h  file  and  test  the  value  of  the  macro
+   cursor_address.
+
+    Tuning for Speed
+
+   Use  the  addchstr()  family  of functions for fast screen-painting of
+   text  when  you know the text does not contain any control characters.
+   Try  to  make attribute changes infrequent on your screens. Do not use
+   the immedok() option!
+
+    Special Features of NCURSES
+
+   The  wresize()  function  allows  you to resize a window in place. The
+   associated   resizeterm()  function  simplifies  the  construction  of
+   SIGWINCH handlers, for resizing all windows.
+
+   The define_key() function allows you to define at runtime function-key
+   control  sequences  which  are  not  in  the terminal description. The
+   keyok()   function   allows  you  to  temporarily  enable  or  disable
+   interpretation of any function-key control sequence.
+
+   The use_default_colors() function allows you to construct applications
+   which  can use the terminal's default foreground and background colors
+   as  an  additional "default" color. Several terminal emulators support
+   this feature, which is based on ISO 6429.
+
+   Ncurses  supports  up 16 colors, unlike SVr4 curses which defines only
+   8. While most terminals which provide color allow only 8 colors, about
+   a quarter (including XFree86 xterm) support 16 colors.
+
+  Compatibility with Older Versions
+
+   Despite  our  best efforts, there are some differences between ncurses
+   and  the  (undocumented!)  behavior  of  older curses implementations.
+   These  arise from ambiguities or omissions in the documentation of the
+   API.
+
+    Refresh of Overlapping Windows
+
+   If  you  define two windows A and B that overlap, and then alternately
+   scribble  on  and  refresh  them,  the changes made to the overlapping
+   region  under  historic  curses  versions  were  often  not documented
+   precisely.
+
+   To  understand why this is a problem, remember that screen updates are
+   calculated  between  two  representations  of  the entire display. The
+   documentation  says that when you refresh a window, it is first copied
+   to  the  virtual screen, and then changes are calculated to update the
+   physical  screen (and applied to the terminal). But "copied to" is not
+   very specific, and subtle differences in how copying works can produce
+   different behaviors in the case where two overlapping windows are each
+   being refreshed at unpredictable intervals.
+
+   What  happens to the overlapping region depends on what wnoutrefresh()
+   does  with  its  argument  --  what portions of the argument window it
+   copies  to  the virtual screen. Some implementations do "change copy",
+   copying  down  only locations in the window that have changed (or been
+   marked  changed  with wtouchln() and friends). Some implementations do
+   "entire  copy",  copying  all  window  locations to the virtual screen
+   whether or not they have changed.
+
+   The  ncurses  library  itself  has  not always been consistent on this
+   score.  Due  to  a  bug,  versions  1.8.7  to  1.9.8a did entire copy.
+   Versions  1.8.6  and  older,  and  versions 1.9.9 and newer, do change
+   copy.
+
+   For  most  commercial curses implementations, it is not documented and
+   not  known  for sure (at least not to the ncurses maintainers) whether
+   they  do  change  copy or entire copy. We know that System V release 3
+   curses  has  logic in it that looks like an attempt to do change copy,
+   but  the  surrounding  logic and data representations are sufficiently
+   complex,  and  our knowledge sufficiently indirect, that it is hard to
+   know  whether  this  is  reliable.  It  is  not  clear  what  the SVr4
+   documentation  and XSI standard intend. The XSI Curses standard barely
+   mentions  wnoutrefresh();  the  SVr4  documents  seem to be describing
+   entire-copy, but it is possible with some effort and straining to read
+   them the other way.
+
+   It  might  therefore  be unwise to rely on either behavior in programs
+   that  might  have  to  be  linked  with  other curses implementations.
+   Instead,  you  can do an explicit touchwin() before the wnoutrefresh()
+   call to guarantee an entire-contents copy anywhere.
+
+   The  really clean way to handle this is to use the panels library. If,
+   when  you want a screen update, you do update_panels(), it will do all
+   the  necessary  wnoutrefresh() calls for whatever panel stacking order
+   you  have  defined. Then you can do one doupdate() and there will be a
+   single burst of physical I/O that will do all your updates.
+
+    Background Erase
+
+   If you have been using a very old versions of ncurses (1.8.7 or older)
+   you  may be surprised by the behavior of the erase functions. In older
+   versions,  erased  areas of a window were filled with a blank modified
+   by  the  window's  current attribute (as set by wattrset(), wattron(),
+   wattroff() and friends).
+
+   In  newer  versions,  this is not so. Instead, the attribute of erased
+   blanks  is  normal  unless  and  until it is modified by the functions
+   bkgdset() or wbkgdset().
+
+   This change in behavior conforms ncurses to System V Release 4 and the
+   XSI Curses standard.
+
+  XSI Curses Conformance
+
+   The  ncurses  library is intended to be base-level conformant with the
+   XSI  Curses  standard  from  X/Open.  Many extended-level features (in
+   fact,  almost all features not directly concerned with wide characters
+   and internationalization) are also supported.
+
+   One  effect  of  XSI  conformance  is the change in behavior described
+   under "Background Erase -- Compatibility with Old Versions".
+
+   Also,  ncurses  meets the XSI requirement that every macro entry point
+   have  a  corresponding  function  which  may  be  linked  (and will be
+   prototype-checked) if the macro definition is disabled with #undef.
+
+The Panels Library
+
+   The  ncurses  library  by  itself  provides  good  support  for screen
+   displays in which the windows are tiled (non-overlapping). In the more
+   general  case  that  windows  may overlap, you have to use a series of
+   wnoutrefresh()  calls  followed  by a doupdate(), and be careful about
+   the order you do the window refreshes in. It has to be bottom-upwards,
+   otherwise parts of windows that should be obscured will show through.
+
+   When  your  interface design is such that windows may dive deeper into
+   the  visibility  stack  or  pop  to  the top at runtime, the resulting
+   book-keeping  can  be  tedious  and  difficult to get right. Hence the
+   panels library.
+
+   The  panel  library  first  appeared  in  AT&T  System  V. The version
+   documented here is the panel code distributed with ncurses.
+
+  Compiling With the Panels Library
+
+   Your  panels-using modules must import the panels library declarations
+   with
+          #include <panel.h>
+
+   and must be linked explicitly with the panels library using an -lpanel
+   argument.  Note  that  they  must  also  link the ncurses library with
+   -lncurses. Many linkers are two-pass and will accept either order, but
+   it is still good practice to put -lpanel first and -lncurses second.
+
+  Overview of Panels
+
+   A  panel  object  is  a window that is implicitly treated as part of a
+   deck  including  all  other  panel  objects.  The deck has an implicit
+   bottom-to-top  visibility order. The panels library includes an update
+   function (analogous to refresh()) that displays all panels in the deck
+   in  the proper order to resolve overlaps. The standard window, stdscr,
+   is considered below all panels.
+
+   Details  on  the  panels  functions are available in the man pages. We
+   will just hit the highlights here.
+
+   You  create  a  panel from a window by calling new_panel() on a window
+   pointer.  It  then  becomes the top of the deck. The panel's window is
+   available as the value of panel_window() called with the panel pointer
+   as argument.
+
+   You  can  delete  a  panel (removing it from the deck) with del_panel.
+   This  will  not  deallocate the associated window; you have to do that
+   yourself.  You can replace a panel's window with a different window by
+   calling  replace_window.  The new window may be of different size; the
+   panel  code  will  re-compute  all  overlaps.  This operation does not
+   change the panel's position in the deck.
+
+   To  move  a  panel's window, use move_panel(). The mvwin() function on
+   the  panel's  window  is not sufficient because it does not update the
+   panels  library's  representation  of  where  the  windows  are.  This
+   operation leaves the panel's depth, contents, and size unchanged.
+
+   Two   functions   (top_panel(),   bottom_panel())   are  provided  for
+   rearranging the deck. The first pops its argument window to the top of
+   the  deck;  the second sends it to the bottom. Either operation leaves
+   the panel's screen location, contents, and size unchanged.
+
+   The  function update_panels() does all the wnoutrefresh() calls needed
+   to prepare for doupdate() (which you must call yourself, afterwards).
+
+   Typically,  you  will want to call update_panels() and doupdate() just
+   before accepting command input, once in each cycle of interaction with
+   the  user.  If  you  call  update_panels()  after each and every panel
+   write,  you  will  generate  a lot of unnecessary refresh activity and
+   screen flicker.
+
+  Panels, Input, and the Standard Screen
+
+   You should not mix wnoutrefresh() or wrefresh() operations with panels
+   code;  this will work only if the argument window is either in the top
+   panel or unobscured by any other panels.
+
+   The  stsdcr  window  is  a  special  case.  It is considered below all
+   panels. Because changes to panels may obscure parts of stdscr, though,
+   you  should  call update_panels() before doupdate() even when you only
+   change stdscr.
+
+   Note  that  wgetch  automatically  calls  wrefresh.  Therefore, before
+   requesting  input  from  a  panel window, you need to be sure that the
+   panel is totally unobscured.
+
+   There  is  presently  no  way to display changes to one obscured panel
+   without repainting all panels.
+
+  Hiding Panels
+
+   It  is  possible  to  remove  a  panel  from the deck temporarily; use
+   hide_panel  for this. Use show_panel() to render it visible again. The
+   predicate  function  panel_hidden  tests  whether  or  not  a panel is
+   hidden.
+
+   The panel_update code ignores hidden panels. You cannot do top_panel()
+   or  bottom_panel  on  a  hidden  panel().  Other panels operations are
+   applicable.
+
+  Miscellaneous Other Facilities
+
+   It  is possible to navigate the deck using the functions panel_above()
+   and  panel_below.  Handed a panel pointer, they return the panel above
+   or  below  that  panel.  Handed  NULL,  they return the bottom-most or
+   top-most panel.
+
+   Every  panel  has  an  associated  user pointer, not used by the panel
+   code,  to  which  you  can  attach  application data. See the man page
+   documentation of set_panel_userptr() and panel_userptr for details.
+
+The Menu Library
+
+   A menu is a screen display that assists the user to choose some subset
+   of  a  given set of items. The menu library is a curses extension that
+   supports  easy  programming  of  menu  hierarchies  with a uniform but
+   flexible interface.
+
+   The  menu  library  first  appeared  in  AT&T  System  V.  The version
+   documented here is the menu code distributed with ncurses.
+
+  Compiling With the menu Library
+
+   Your menu-using modules must import the menu library declarations with
+          #include <menu.h>
+
+   and  must  be linked explicitly with the menus library using an -lmenu
+   argument.  Note  that  they  must  also  link the ncurses library with
+   -lncurses. Many linkers are two-pass and will accept either order, but
+   it is still good practice to put -lmenu first and -lncurses second.
+
+  Overview of Menus
+
+   The  menus  created  by  this  library consist of collections of items
+   including  a  name  string part and a description string part. To make
+   menus,  you  create  groups  of these items and connect them with menu
+   frame objects.
+
+   The  menu can then by posted, that is written to an associated window.
+   Actually, each menu has two associated windows; a containing window in
+   which  the  programmer can scribble titles or borders, and a subwindow
+   in which the menu items proper are displayed. If this subwindow is too
+   small  to  display  all the items, it will be a scrollable viewport on
+   the collection of items.
+
+   A  menu may also be unposted (that is, undisplayed), and finally freed
+   to  make  the  storage  associated with it and its items available for
+   re-use.
+
+   The general flow of control of a menu program looks like this:
+    1. Initialize curses.
+    2. Create the menu items, using new_item().
+    3. Create the menu using new_menu().
+    4. Post the menu using post_menu().
+    5. Refresh the screen.
+    6. Process user requests via an input loop.
+    7. Unpost the menu using unpost_menu().
+    8. Free the menu, using free_menu().
+    9. Free the items using free_item().
+   10. Terminate curses.
+
+  Selecting items
+
+   Menus  may  be  multi-valued  or  (the default) single-valued (see the
+   manual  page  menu_opts(3x)  to  see  how to change the default). Both
+   types always have a current item.
+
+   From  a  single-valued  menu you can read the selected value simply by
+   looking  at  the  current  item. From a multi-valued menu, you get the
+   selected  set  by  looping through the items applying the item_value()
+   predicate  function.  Your  menu-processing  code can use the function
+   set_item_value() to flag the items in the select set.
+
+   Menu   items   can  be  made  unselectable  using  set_item_opts()  or
+   item_opts_off()  with  the  O_SELECTABLE  argument.  This  is the only
+   option  so  far  defined for menus, but it is good practice to code as
+   though other option bits might be on.
+
+  Menu Display
+
+   The  menu  library  calculates a minimum display size for your window,
+   based on the following variables:
+     * The number and maximum length of the menu items
+     * Whether the O_ROWMAJOR option is enabled
+     * Whether display of descriptions is enabled
+     * Whatever menu format may have been set by the programmer
+     * The  length of the menu mark string used for highlighting selected
+       items
+
+   The  function  set_menu_format() allows you to set the maximum size of
+   the viewport or menu page that will be used to display menu items. You
+   can retrieve any format associated with a menu with menu_format(). The
+   default format is rows=16, columns=1.
+
+   The actual menu page may be smaller than the format size. This depends
+   on  the item number and size and whether O_ROWMAJOR is on. This option
+   (on  by  default) causes menu items to be displayed in a "raster-scan"
+   pattern, so that if more than one item will fit horizontally the first
+   couple  of  items  are side-by-side in the top row. The alternative is
+   column-major  display,  which  tries to put the first several items in
+   the first column.
+
+   As  mentioned above, a menu format not large enough to allow all items
+   to  fit  on-screen  will  result  in a menu display that is vertically
+   scrollable.
+
+   You  can  scroll  it  with  requests to the menu driver, which will be
+   described in the section on menu input handling.
+
+   Each  menu  has a mark string used to visually tag selected items; see
+   the menu_mark(3x) manual page for details. The mark string length also
+   influences the menu page size.
+
+   The  function  scale_menu()  returns the minimum display size that the
+   menu  code  computes  from  all  these  factors.  There are other menu
+   display  attributes  including  a  select  attribute, an attribute for
+   selectable  items,  an  attribute  for  unselectable  items, and a pad
+   character used to separate item name text from description text. These
+   have  reasonable  defaults which the library allows you to change (see
+   the menu_attribs(3x) manual page.
+
+  Menu Windows
+
+   Each  menu has, as mentioned previously, a pair of associated windows.
+   Both these windows are painted when the menu is posted and erased when
+   the menu is unposted.
+
+   The  outer  or  frame  window  is  not  otherwise  touched by the menu
+   routines. It exists so the programmer can associate a title, a border,
+   or  perhaps  help text with the menu and have it properly refreshed or
+   erased at post/unpost time. The inner window or subwindow is where the
+   current menu page is displayed.
+
+   By  default,  both  windows  are  stdscr.  You  can  set them with the
+   functions in menu_win(3x).
+
+   When  you  call post_menu(), you write the menu to its subwindow. When
+   you  call  unpost_menu(), you erase the subwindow, However, neither of
+   these  actually  modifies  the  screen. To do that, call wrefresh() or
+   some equivalent.
+
+  Processing Menu Input
+
+   The  main  loop of your menu-processing code should call menu_driver()
+   repeatedly.  The first argument of this routine is a menu pointer; the
+   second  is  a  menu  command  code. You should write an input-fetching
+   routine that maps input characters to menu command codes, and pass its
+   output  to  menu_driver(). The menu command codes are fully documented
+   in menu_driver(3x).
+
+   The  simplest  group of command codes is REQ_NEXT_ITEM, REQ_PREV_ITEM,
+   REQ_FIRST_ITEM,     REQ_LAST_ITEM,     REQ_UP_ITEM,     REQ_DOWN_ITEM,
+   REQ_LEFT_ITEM,  REQ_RIGHT_ITEM.  These  change  the currently selected
+   item.  These  requests may cause scrolling of the menu page if it only
+   partially displayed.
+
+   There  are  explicit  requests  for  scrolling  which  also change the
+   current  item  (because  the  select location does not change, but the
+   item    there   does).   These   are   REQ_SCR_DLINE,   REQ_SCR_ULINE,
+   REQ_SCR_DPAGE, and REQ_SCR_UPAGE.
+
+   The  REQ_TOGGLE_ITEM  selects or deselects the current item. It is for
+   use  in multi-valued menus; if you use it with O_ONEVALUE on, you will
+   get an error return (E_REQUEST_DENIED).
+
+   Each  menu  has  an associated pattern buffer. The menu_driver() logic
+   tries  to  accumulate  printable  ASCII  characters  passed in in that
+   buffer;  when  it  matches a prefix of an item name, that item (or the
+   next  matching  item)  is selected. If appending a character yields no
+   new  match,  that  character  is  deleted from the pattern buffer, and
+   menu_driver() returns E_NO_MATCH.
+
+   Some  requests  change the pattern buffer directly: REQ_CLEAR_PATTERN,
+   REQ_BACK_PATTERN,  REQ_NEXT_MATCH,  REQ_PREV_MATCH. The latter two are
+   useful  when  pattern  buffer  input  matches  more than one item in a
+   multi-valued menu.
+
+   Each  successful  scroll or item navigation request clears the pattern
+   buffer.  It is also possible to set the pattern buffer explicitly with
+   set_menu_pattern().
+
+   Finally,  menu  driver  requests  above  the  constant MAX_COMMAND are
+   considered   application-specific  commands.  The  menu_driver()  code
+   ignores them and returns E_UNKNOWN_COMMAND.
+
+  Miscellaneous Other Features
+
+   Various  menu  options can affect the processing and visual appearance
+   and input processing of menus. See menu_opts(3x) for details.
+
+   It  is possible to change the current item from application code; this
+   is  useful  if  you  want to write your own navigation requests. It is
+   also  possible  to explicitly set the top row of the menu display. See
+   mitem_current(3x).  If  your  application  needs  to  change  the menu
+   subwindow  cursor for any reason, pos_menu_cursor() will restore it to
+   the correct location for continuing menu driver processing.
+
+   It  is  possible  to set hooks to be called at menu initialization and
+   wrapup   time,   and   whenever   the   selected   item  changes.  See
+   menu_hook(3x).
+
+   Each  item, and each menu, has an associated user pointer on which you
+   can hang application data. See mitem_userptr(3x) and menu_userptr(3x).
+
+The Forms Library
+
+   The  form library is a curses extension that supports easy programming
+   of on-screen forms for data entry and program control.
+
+   The  form  library  first  appeared  in  AT&T  System  V.  The version
+   documented here is the form code distributed with ncurses.
+
+  Compiling With the form Library
+
+   Your form-using modules must import the form library declarations with
+          #include <form.h>
+
+   and  must  be linked explicitly with the forms library using an -lform
+   argument.  Note  that  they  must  also  link the ncurses library with
+   -lncurses. Many linkers are two-pass and will accept either order, but
+   it is still good practice to put -lform first and -lncurses second.
+
+  Overview of Forms
+
+   A  form  is  a  collection of fields; each field may be either a label
+   (explanatory  text)  or  a  data-entry  location.  Long  forms  may be
+   segmented into pages; each entry to a new page clears the screen.
+
+   To  make forms, you create groups of fields and connect them with form
+   frame objects; the form library makes this relatively simple.
+
+   Once  defined,  a form can be posted, that is written to an associated
+   window.  Actually,  each form has two associated windows; a containing
+   window  in  which the programmer can scribble titles or borders, and a
+   subwindow in which the form fields proper are displayed.
+
+   As  the  form  user  fills out the posted form, navigation and editing
+   keys  support  movement between fields, editing keys support modifying
+   field,  and plain text adds to or changes data in a current field. The
+   form  library  allows you (the forms designer) to bind each navigation
+   and  editing  key  to any keystroke accepted by curses Fields may have
+   validation  conditions on them, so that they check input data for type
+   and  value.  The form library supplies a rich set of pre-defined field
+   types, and makes it relatively easy to define new ones.
+
+   Once its transaction is completed (or aborted), a form may be unposted
+   (that  is,  undisplayed),  and  finally  freed  to  make  the  storage
+   associated with it and its items available for re-use.
+
+   The general flow of control of a form program looks like this:
+    1. Initialize curses.
+    2. Create the form fields, using new_field().
+    3. Create the form using new_form().
+    4. Post the form using post_form().
+    5. Refresh the screen.
+    6. Process user requests via an input loop.
+    7. Unpost the form using unpost_form().
+    8. Free the form, using free_form().
+    9. Free the fields using free_field().
+   10. Terminate curses.
+
+   Note  that  this  looks  much  like  a  menu program; the form library
+   handles  tasks  which  are in many ways similar, and its interface was
+   obviously  designed  to  resemble  that  of  the menu library wherever
+   possible.
+
+   In  forms  programs,  however, the "process user requests" is somewhat
+   more   complicated   than  for  menus.  Besides  menu-like  navigation
+   operations, the menu driver loop has to support field editing and data
+   validation.
+
+  Creating and Freeing Fields and Forms
+
+   The basic function for creating fields is new_field():
+FIELD *new_field(int height, int width,   /* new field size */
+                 int top, int left,       /* upper left corner */
+                 int offscreen,           /* number of offscreen rows */
+                 int nbuf);               /* number of working buffers */
+
+   Menu  items  always  occupy  a  single  row, but forms fields may have
+   multiple  rows.  So  new_field()  requires  you to specify a width and
+   height  (the  first  two  arguments,  which  mist both be greater than
+   zero).
+
+   You must also specify the location of the field's upper left corner on
+   the  screen  (the  third  and  fourth arguments, which must be zero or
+   greater).  Note  that  these  coordinates  are  relative  to  the form
+   subwindow,  which will coincide with stdscr by default but need not be
+   stdscr if you have done an explicit set_form_win() call.
+
+   The  fifth argument allows you to specify a number of off-screen rows.
+   If  this  is zero, the entire field will always be displayed. If it is
+   nonzero,  the  form  will  be  scrollable,  with  only one screen-full
+   (initially  the  top  part) displayed at any given time. If you make a
+   field  dynamic and grow it so it will no longer fit on the screen, the
+   form  will  become  scrollable  even  if  the  offscreen  argument was
+   initially zero.
+
+   The  forms library allocates one working buffer per field; the size of
+   each buffer is ((height + offscreen)*width + 1, one character for each
+   position in the field plus a NUL terminator. The sixth argument is the
+   number  of  additional  data  buffers  to allocate for the field; your
+   application can use them for its own purposes.
+FIELD *dup_field(FIELD *field,            /* field to copy */
+                 int top, int left);      /* location of new copy */
+
+   The  function  dup_field()  duplicates  an  existing  field  at  a new
+   location.  Size  and  buffering information are copied; some attribute
+   flags  and  status  bits  are  not  (see  the  form_field_new(3X)  for
+   details).
+FIELD *link_field(FIELD *field,           /* field to copy */
+                  int top, int left);     /* location of new copy */
+
+   The  function  link_field() also duplicates an existing field at a new
+   location.  The difference from dup_field() is that it arranges for the
+   new field's buffer to be shared with the old one.
+
+   Besides  the obvious use in making a field editable from two different
+   form pages, linked fields give you a way to hack in dynamic labels. If
+   you  declare  several fields linked to an original, and then make them
+   inactive,  changes  from  the original will still be propagated to the
+   linked fields.
+
+   As  with duplicated fields, linked fields have attribute bits separate
+   from the original.
+
+   As  you  might  guess,  all these field-allocations return NULL if the
+   field  allocation  is  not  possible  due to an out-of-memory error or
+   out-of-bounds arguments.
+
+   To connect fields to a form, use
+FORM *new_form(FIELD **fields);
+
+   This  function  expects  to  see  a  NULL-terminated  array  of  field
+   pointers.  Said fields are connected to a newly-allocated form object;
+   its address is returned (or else NULL if the allocation fails).
+
+   Note  that  new_field()  does  not copy the pointer array into private
+   storage;  if you modify the contents of the pointer array during forms
+   processing,  all manner of bizarre things might happen. Also note that
+   any given field may only be connected to one form.
+
+   The  functions  free_field() and free_form are available to free field
+   and  form objects. It is an error to attempt to free a field connected
+   to a form, but not vice-versa; thus, you will generally free your form
+   objects first.
+
+  Fetching and Changing Field Attributes
+
+   Each  form  field  has  a  number  of  location  and  size  attributes
+   associated  with  it. There are other field attributes used to control
+   display and editing of the field. Some (for example, the O_STATIC bit)
+   involve  sufficient  complications  to be covered in sections of their
+   own later on. We cover the functions used to get and set several basic
+   attributes here.
+
+   When a field is created, the attributes not specified by the new_field
+   function  are  copied  from  an  invisible  system  default  field. In
+   attribute-setting  and -fetching functions, the argument NULL is taken
+   to mean this field. Changes to it persist as defaults until your forms
+   application terminates.
+
+    Fetching Size and Location Data
+
+   You can retrieve field sizes and locations through:
+int field_info(FIELD *field,              /* field from which to fetch */
+               int *height, *int width,   /* field size */
+               int *top, int *left,       /* upper left corner */
+               int *offscreen,            /* number of offscreen rows */
+               int *nbuf);                /* number of working buffers */
+
+   This  function is a sort of inverse of new_field(); instead of setting
+   size  and  location attributes of a new field, it fetches them from an
+   existing one.
+
+    Changing the Field Location
+
+   It is possible to move a field's location on the screen:
+int move_field(FIELD *field,              /* field to alter */
+               int top, int left);        /* new upper-left corner */
+
+   You can, of course. query the current location through field_info().
+
+    The Justification Attribute
+
+   One-line  fields  may be unjustified, justified right, justified left,
+   or centered. Here is how you manipulate this attribute:
+int set_field_just(FIELD *field,          /* field to alter */
+                   int justmode);         /* mode to set */
+
+int field_just(FIELD *field);             /* fetch mode of field */
+
+   The   mode   values  accepted  and  returned  by  this  functions  are
+   preprocessor  macros NO_JUSTIFICATION, JUSTIFY_RIGHT, JUSTIFY_LEFT, or
+   JUSTIFY_CENTER.
+
+    Field Display Attributes
+
+   For  each  field,  you  can  set  a  foreground  attribute for entered
+   characters,  a  background  attribute  for the entire field, and a pad
+   character  for the unfilled portion of the field. You can also control
+   pagination of the form.
+
+   This  group of four field attributes controls the visual appearance of
+   the  field on the screen, without affecting in any way the data in the
+   field buffer.
+int set_field_fore(FIELD *field,          /* field to alter */
+                   chtype attr);          /* attribute to set */
+
+chtype field_fore(FIELD *field);          /* field to query */
+
+int set_field_back(FIELD *field,          /* field to alter */
+                   chtype attr);          /* attribute to set */
+
+chtype field_back(FIELD *field);          /* field to query */
+
+int set_field_pad(FIELD *field,           /* field to alter */
+                 int pad);                /* pad character to set */
+
+chtype field_pad(FIELD *field);
+
+int set_new_page(FIELD *field,            /* field to alter */
+                 int flag);               /* TRUE to force new page */
+
+chtype new_page(FIELD *field);            /* field to query */
+
+   The attributes set and returned by the first four functions are normal
+   curses(3x)  display  attribute  values  (A_STANDOUT, A_BOLD, A_REVERSE
+   etc).  The page bit of a field controls whether it is displayed at the
+   start of a new form screen.
+
+    Field Option Bits
+
+   There  is  also a large collection of field option bits you can set to
+   control  various  aspects of forms processing. You can manipulate them
+   with these functions:
+int set_field_opts(FIELD *field,          /* field to alter */
+                   int attr);             /* attribute to set */
+
+int field_opts_on(FIELD *field,           /* field to alter */
+                  int attr);              /* attributes to turn on */
+
+int field_opts_off(FIELD *field,          /* field to alter */
+                   int attr);             /* attributes to turn off */
+
+int field_opts(FIELD *field);             /* field to query */
+
+   By default, all options are on. Here are the available option bits:
+
+   O_VISIBLE
+          Controls  whether  the  field  is visible on the screen. Can be
+          used  during form processing to hide or pop up fields depending
+          on the value of parent fields.
+
+   O_ACTIVE
+          Controls  whether  the  field is active during forms processing
+          (i.e.  visited  by  form  navigation keys). Can be used to make
+          labels  or  derived  fields with buffer values alterable by the
+          forms application, not the user.
+
+   O_PUBLIC
+          Controls  whether data is displayed during field entry. If this
+          option  is  turned  off on a field, the library will accept and
+          edit  data  in that field, but it will not be displayed and the
+          visible  field  cursor  will  not  move.  You  can turn off the
+          O_PUBLIC bit to define password fields.
+
+   O_EDIT
+          Controls  whether  the  field's data can be modified. When this
+          option  is off, all editing requests except REQ_PREV_CHOICE and
+          REQ_NEXT_CHOICE  will fail. Such read-only fields may be useful
+          for help messages.
+
+   O_WRAP
+          Controls word-wrapping in multi-line fields. Normally, when any
+          character  of  a  (blank-separated) word reaches the end of the
+          current  line,  the  entire  word  is  wrapped to the next line
+          (assuming there is one). When this option is off, the word will
+          be split across the line break.
+
+   O_BLANK
+          Controls  field  blanking.  When  this option is on, entering a
+          character  at  the first field position erases the entire field
+          (except for the just-entered character).
+
+   O_AUTOSKIP
+          Controls  automatic  skip  to  next  field when this one fills.
+          Normally,  when  the  forms user tries to type more data into a
+          field  than will fit, the editing location jumps to next field.
+          When this option is off, the user's cursor will hang at the end
+          of  the  field.  This  option is ignored in dynamic fields that
+          have not reached their size limit.
+
+   O_NULLOK
+          Controls   whether  validation  is  applied  to  blank  fields.
+          Normally,  it  is not; the user can leave a field blank without
+          invoking  the usual validation check on exit. If this option is
+          off on a field, exit from it will invoke a validation check.
+
+   O_PASSOK
+          Controls whether validation occurs on every exit, or only after
+          the  field  is  modified.  Normally the latter is true. Setting
+          O_PASSOK  may be useful if your field's validation function may
+          change during forms processing.
+
+   O_STATIC
+          Controls  whether the field is fixed to its initial dimensions.
+          If  you  turn  this  off,  the  field  becomes dynamic and will
+          stretch to fit entered data.
+
+   A  field's  options  cannot  be  changed  while the field is currently
+   selected.  However,  options  may be changed on posted fields that are
+   not current.
+
+   The option values are bit-masks and can be composed with logical-or in
+   the obvious way.
+
+  Field Status
+
+   Every field has a status flag, which is set to FALSE when the field is
+   created  and  TRUE when the value in field buffer 0 changes. This flag
+   can be queried and set directly:
+int set_field_status(FIELD *field,      /* field to alter */
+                   int status);         /* mode to set */
+
+int field_status(FIELD *field);         /* fetch mode of field */
+
+   Setting  this  flag under program control can be useful if you use the
+   same form repeatedly, looking for modified fields each time.
+
+   Calling  field_status()  on  a  field not currently selected for input
+   will return a correct value. Calling field_status() on a field that is
+   currently  selected for input may not necessarily give a correct field
+   status value, because entered data is not necessarily copied to buffer
+   zero  before the exit validation check. To guarantee that the returned
+   status  value  reflects reality, call field_status() either (1) in the
+   field's  exit validation check routine, (2) from the field's or form's
+   initialization   or   termination   hooks,   or   (3)   just  after  a
+   REQ_VALIDATION request has been processed by the forms driver.
+
+  Field User Pointer
+
+   Each  field  structure contains one character pointer slot that is not
+   used  by  the forms library. It is intended to be used by applications
+   to store private per-field data. You can manipulate it with:
+int set_field_userptr(FIELD *field,       /* field to alter */
+                   char *userptr);        /* mode to set */
+
+char *field_userptr(FIELD *field);        /* fetch mode of field */
+
+   (Properly,  this  user  pointer field ought to have (void *) type. The
+   (char *) type is retained for System V compatibility.)
+
+   It  is  valid  to  set  the  user pointer of the default field (with a
+   set_field_userptr()  call  passed  a  NULL  field pointer.) When a new
+   field  is  created,  the  default-field  user  pointer  is  copied  to
+   initialize the new field's user pointer.
+
+  Variable-Sized Fields
+
+   Normally,  a  field  is fixed at the size specified for it at creation
+   time.  If,  however, you turn off its O_STATIC bit, it becomes dynamic
+   and  will  automatically  resize  itself  to accommodate data as it is
+   entered.  If the field has extra buffers associated with it, they will
+   grow right along with the main input buffer.
+
+   A  one-line  dynamic  field  will have a fixed height (1) but variable
+   width, scrolling horizontally to display data within the field area as
+   originally  dimensioned  and  located. A multi-line dynamic field will
+   have  a  fixed  width, but variable height (number of rows), scrolling
+   vertically  to  display  data  within  the  field  area  as originally
+   dimensioned and located.
+
+   Normally,  a dynamic field is allowed to grow without limit. But it is
+   possible  to set an upper limit on the size of a dynamic field. You do
+   it with this function:
+int set_max_field(FIELD *field,     /* field to alter (may not be NULL) */
+                   int max_size);   /* upper limit on field size */
+
+   If the field is one-line, max_size is taken to be a column size limit;
+   if  it  is multi-line, it is taken to be a line size limit. To disable
+   any  limit,  use  an argument of zero. The growth limit can be changed
+   whether or not the O_STATIC bit is on, but has no effect until it is.
+
+   The following properties of a field change when it becomes dynamic:
+     * If  there  is  no  growth limit, there is no final position of the
+       field; therefore O_AUTOSKIP and O_NL_OVERLOAD are ignored.
+     * Field justification will be ignored (though whatever justification
+       is set up will be retained internally and can be queried).
+     * The  dup_field() and link_field() calls copy dynamic-buffer sizes.
+       If  the  O_STATIC  option  is set on one of a collection of links,
+       buffer  resizing  will occur only when the field is edited through
+       that link.
+     * The  call  field_info()  will retrieve the original static size of
+       the  field;  use  dynamic_field_info()  to  get the actual dynamic
+       size.
+
+  Field Validation
+
+   By  default,  a  field will accept any data that will fit in its input
+   buffer.  However,  it  is  possible  to  attach a validation type to a
+   field.  If  you  do  this,  any  attempt  to  leave the field while it
+   contains  data that does not match the validation type will fail. Some
+   validation  types also have a character-validity check for each time a
+   character is entered in the field.
+
+   A   field's   validation   check   (if   any)   is   not  called  when
+   set_field_buffer()  modifies the input buffer, nor when that buffer is
+   changed through a linked field.
+
+   The  form library provides a rich set of pre-defined validation types,
+   and  gives  you  the capability to define custom ones of your own. You
+   can  examine and change field validation attributes with the following
+   functions:
+int set_field_type(FIELD *field,          /* field to alter */
+                   FIELDTYPE *ftype,      /* type to associate */
+                   ...);                  /* additional arguments*/
+
+FIELDTYPE *field_type(FIELD *field);      /* field to query */
+
+   The  validation  type  of  a  field  is considered an attribute of the
+   field.  As  with  other field attributes, Also, doing set_field_type()
+   with  a  NULL  field  default  will  change  the  system  default  for
+   validation of newly-created fields.
+
+   Here are the pre-defined validation types:
+
+    TYPE_ALPHA
+
+   This  field  type  accepts  alphabetic  data; no blanks, no digits, no
+   special  characters  (this  is checked at character-entry time). It is
+   set up with:
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_ALPHA,            /* type to associate */
+                   int width);            /* maximum width of field */
+
+   The  width  argument  sets a minimum width of data. Typically you will
+   want  to  set this to the field width; if it is greater than the field
+   width,  the validation check will always fail. A minimum width of zero
+   makes field completion optional.
+
+    TYPE_ALNUM
+
+   This  field  type  accepts  alphabetic  data and digits; no blanks, no
+   special  characters  (this  is checked at character-entry time). It is
+   set up with:
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_ALNUM,            /* type to associate */
+                   int width);            /* maximum width of field */
+
+   The  width  argument sets a minimum width of data. As with TYPE_ALPHA,
+   typically  you  will  want  to  set  this to the field width; if it is
+   greater than the field width, the validation check will always fail. A
+   minimum width of zero makes field completion optional.
+
+    TYPE_ENUM
+
+   This  type  allows  you  to  restrict  a  field's values to be among a
+   specified  set  of  string  values (for example, the two-letter postal
+   codes for U.S. states). It is set up with:
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_ENUM,             /* type to associate */
+                   char **valuelist;      /* list of possible values */
+                   int checkcase;         /* case-sensitive? */
+                   int checkunique);      /* must specify uniquely? */
+
+   The  valuelist parameter must point at a NULL-terminated list of valid
+   strings.  The  checkcase  argument, if true, makes comparison with the
+   string case-sensitive.
+
+   When  the user exits a TYPE_ENUM field, the validation procedure tries
+   to  complete  the  data  in the buffer to a valid entry. If a complete
+   choice  string has been entered, it is of course valid. But it is also
+   possible to enter a prefix of a valid string and have it completed for
+   you.
+
+   By  default,  if  you enter such a prefix and it matches more than one
+   value  in  the  string list, the prefix will be completed to the first
+   matching value. But the checkunique argument, if true, requires prefix
+   matches to be unique in order to be valid.
+
+   The   REQ_NEXT_CHOICE   and  REQ_PREV_CHOICE  input  requests  can  be
+   particularly useful with these fields.
+
+    TYPE_INTEGER
+
+   This field type accepts an integer. It is set up as follows:
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_INTEGER,          /* type to associate */
+                   int padding,           /* # places to zero-pad to */
+                   int vmin, int vmax);   /* valid range */
+
+   Valid  characters consist of an optional leading minus and digits. The
+   range check is performed on exit. If the range maximum is less than or
+   equal to the minimum, the range is ignored.
+
+   If the value passes its range check, it is padded with as many leading
+   zero digits as necessary to meet the padding argument.
+
+   A TYPE_INTEGER value buffer can conveniently be interpreted with the C
+   library function atoi(3).
+
+    TYPE_NUMERIC
+
+   This field type accepts a decimal number. It is set up as follows:
+int set_field_type(FIELD *field,              /* field to alter */
+                   TYPE_NUMERIC,              /* type to associate */
+                   int padding,               /* # places of precision */
+                   double vmin, double vmax); /* valid range */
+
+   Valid  characters  consist  of  an  optional leading minus and digits.
+   possibly  including a decimal point. If your system supports locale's,
+   the  decimal  point  character  used  must  be the one defined by your
+   locale.  The range check is performed on exit. If the range maximum is
+   less than or equal to the minimum, the range is ignored.
+
+   If  the  value  passes  its  range  check,  it  is padded with as many
+   trailing zero digits as necessary to meet the padding argument.
+
+   A TYPE_NUMERIC value buffer can conveniently be interpreted with the C
+   library function atof(3).
+
+    TYPE_REGEXP
+
+   This  field type accepts data matching a regular expression. It is set
+   up as follows:
+int set_field_type(FIELD *field,          /* field to alter */
+                   TYPE_REGEXP,           /* type to associate */
+                   char *regexp);         /* expression to match */
+
+   The  syntax  for  regular expressions is that of regcomp(3). The check
+   for regular-expression match is performed on exit.
+
+  Direct Field Buffer Manipulation
+
+   The chief attribute of a field is its buffer contents. When a form has
+   been  completed,  your  application usually needs to know the state of
+   each field buffer. You can find this out with:
+char *field_buffer(FIELD *field,          /* field to query */
+                   int bufindex);         /* number of buffer to query */
+
+   Normally,  the state of the zero-numbered buffer for each field is set
+   by the user's editing actions on that field. It is sometimes useful to
+   be  able  to set the value of the zero-numbered (or some other) buffer
+   from your application:
+int set_field_buffer(FIELD *field,        /* field to alter */
+                   int bufindex,          /* number of buffer to alter */
+                   char *value);          /* string value to set */
+
+   If  the  field  is  not  large  enough  and  cannot  be  resized  to a
+   sufficiently large size to contain the specified value, the value will
+   be truncated to fit.
+
+   Calling  field_buffer() with a null field pointer will raise an error.
+   Calling  field_buffer()  on  a  field not currently selected for input
+   will return a correct value. Calling field_buffer() on a field that is
+   currently  selected for input may not necessarily give a correct field
+   buffer value, because entered data is not necessarily copied to buffer
+   zero  before the exit validation check. To guarantee that the returned
+   buffer  value  reflects  on-screen reality, call field_buffer() either
+   (1) in the field's exit validation check routine, (2) from the field's
+   or  form's  initialization  or  termination hooks, or (3) just after a
+   REQ_VALIDATION request has been processed by the forms driver.
+
+  Attributes of Forms
+
+   As  with  field  attributes,  form attributes inherit a default from a
+   system default form structure. These defaults can be queried or set by
+   of these functions using a form-pointer argument of NULL.
+
+   The principal attribute of a form is its field list. You can query and
+   change this list with:
+int set_form_fields(FORM *form,           /* form to alter */
+                    FIELD **fields);      /* fields to connect */
+
+char *form_fields(FORM *form);            /* fetch fields of form */
+
+int field_count(FORM *form);              /* count connect fields */
+
+   The  second  argument  of  set_form_fields()  may be a NULL-terminated
+   field pointer array like the one required by new_form(). In that case,
+   the  old  fields  of  the  form  are  disconnected  but not freed (and
+   eligible  to  be  connected  to  other forms), then the new fields are
+   connected.
+
+   It  may  also  be  null, in which case the old fields are disconnected
+   (and not freed) but no new ones are connected.
+
+   The   field_count()  function  simply  counts  the  number  of  fields
+   connected  to a given from. It returns -1 if the form-pointer argument
+   is NULL.
+
+  Control of Form Display
+
+   In  the  overview section, you saw that to display a form you normally
+   start  by  defining  its size (and fields), posting it, and refreshing
+   the  screen.  There  is  an  hidden  step before posting, which is the
+   association  of  the  form  with  a  frame window (actually, a pair of
+   windows)  within  which  it  will  be displayed. By default, the forms
+   library associates every form with the full-screen window stdscr.
+
+   By making this step explicit, you can associate a form with a declared
+   frame window on your screen display. This can be useful if you want to
+   adapt  the  form  display  to different screen sizes, dynamically tile
+   forms  on  the  screen,  or  use a form as part of an interface layout
+   managed by panels.
+
+   The  two  windows associated with each form have the same functions as
+   their  analogues  in  the menu library. Both these windows are painted
+   when the form is posted and erased when the form is unposted.
+
+   The  outer  or  frame  window  is  not  otherwise  touched by the form
+   routines. It exists so the programmer can associate a title, a border,
+   or  perhaps  help text with the form and have it properly refreshed or
+   erased at post/unpost time. The inner window or subwindow is where the
+   current form page is actually displayed.
+
+   In order to declare your own frame window for a form, you will need to
+   know  the  size  of  the  form's  bounding rectangle. You can get this
+   information with:
+int scale_form(FORM *form,                /* form to query */
+               int *rows,                 /* form rows */
+               int *cols);                /* form cols */
+
+   The form dimensions are passed back in the locations pointed to by the
+   arguments.  Once  you have this information, you can use it to declare
+   of windows, then use one of these functions:
+int set_form_win(FORM *form,              /* form to alter */
+                 WINDOW *win);            /* frame window to connect */
+
+WINDOW *form_win(FORM *form);             /* fetch frame window of form */
+
+int set_form_sub(FORM *form,              /* form to alter */
+                 WINDOW *win);            /* form subwindow to connect */
+
+WINDOW *form_sub(FORM *form);             /* fetch form subwindow of form */
+
+   Note  that curses operations, including refresh(), on the form, should
+   be done on the frame window, not the form subwindow.
+
+   It  is  possible  to  check  from  your  application  whether all of a
+   scrollable  field is actually displayed within the menu subwindow. Use
+   these functions:
+int data_ahead(FORM *form);               /* form to be queried */
+
+int data_behind(FORM *form);              /* form to be queried */
+
+   The  function  data_ahead()  returns  TRUE if (a) the current field is
+   one-line  and  has  undisplayed data off to the right, (b) the current
+   field is multi-line and there is data off-screen below it.
+
+   The function data_behind() returns TRUE if the first (upper left hand)
+   character position is off-screen (not being displayed).
+
+   Finally,  there  is  a function to restore the form window's cursor to
+   the value expected by the forms driver:
+int pos_form_cursor(FORM *)               /* form to be queried */
+
+   If your application changes the form window cursor, call this function
+   before   handing  control  back  to  the  forms  driver  in  order  to
+   re-synchronize it.
+
+  Input Processing in the Forms Driver
+
+   The function form_driver() handles virtualized input requests for form
+   navigation, editing, and validation requests, just as menu_driver does
+   for menus (see the section on menu input handling).
+int form_driver(FORM *form,               /* form to pass input to */
+                int request);             /* form request code */
+
+   Your  input  virtualization  function  needs  to  take  input and then
+   convert  it  to  either an alphanumeric character (which is treated as
+   data  to  be  entered  in  the  currently-selected  field), or a forms
+   processing request.
+
+   The   forms   driver  provides  hooks  (through  input-validation  and
+   field-termination  functions)  with  which  your  application code can
+   check that the input taken by the driver matched what was expected.
+
+    Page Navigation Requests
+
+   These  requests  cause  page-level  moves through the form, triggering
+   display of a new form screen.
+
+   REQ_NEXT_PAGE
+          Move to the next form page.
+
+   REQ_PREV_PAGE
+          Move to the previous form page.
+
+   REQ_FIRST_PAGE
+          Move to the first form page.
+
+   REQ_LAST_PAGE
+          Move to the last form page.
+
+   These  requests  treat the list as cyclic; that is, REQ_NEXT_PAGE from
+   the last page goes to the first, and REQ_PREV_PAGE from the first page
+   goes to the last.
+
+    Inter-Field Navigation Requests
+
+   These requests handle navigation between fields on the same page.
+
+   REQ_NEXT_FIELD
+          Move to next field.
+
+   REQ_PREV_FIELD
+          Move to previous field.
+
+   REQ_FIRST_FIELD
+          Move to the first field.
+
+   REQ_LAST_FIELD
+          Move to the last field.
+
+   REQ_SNEXT_FIELD
+          Move to sorted next field.
+
+   REQ_SPREV_FIELD
+          Move to sorted previous field.
+
+   REQ_SFIRST_FIELD
+          Move to the sorted first field.
+
+   REQ_SLAST_FIELD
+          Move to the sorted last field.
+
+   REQ_LEFT_FIELD
+          Move left to field.
+
+   REQ_RIGHT_FIELD
+          Move right to field.
+
+   REQ_UP_FIELD
+          Move up to field.
+
+   REQ_DOWN_FIELD
+          Move down to field.
+
+   These  requests treat the list of fields on a page as cyclic; that is,
+   REQ_NEXT_FIELD   from   the   last   field  goes  to  the  first,  and
+   REQ_PREV_FIELD from the first field goes to the last. The order of the
+   fields for these (and the REQ_FIRST_FIELD and REQ_LAST_FIELD requests)
+   is simply the order of the field pointers in the form array (as set up
+   by new_form() or set_form_fields()
+
+   It  is also possible to traverse the fields as if they had been sorted
+   in  screen-position  order,  so  the  sequence  goes left-to-right and
+   top-to-bottom.   To   do   this,   use   the   second  group  of  four
+   sorted-movement requests.
+
+   Finally, it is possible to move between fields using visual directions
+   up,  down, right, and left. To accomplish this, use the third group of
+   four requests. Note, however, that the position of a form for purposes
+   of these requests is its upper-left corner.
+
+   For   example,  suppose  you  have  a  multi-line  field  B,  and  two
+   single-line fields A and C on the same line with B, with A to the left
+   of  B  and  C  to the right of B. A REQ_MOVE_RIGHT from A will go to B
+   only  if  A, B, and C all share the same first line; otherwise it will
+   skip over B to C.
+
+    Intra-Field Navigation Requests
+
+   These  requests drive movement of the edit cursor within the currently
+   selected field.
+
+   REQ_NEXT_CHAR
+          Move to next character.
+
+   REQ_PREV_CHAR
+          Move to previous character.
+
+   REQ_NEXT_LINE
+          Move to next line.
+
+   REQ_PREV_LINE
+          Move to previous line.
+
+   REQ_NEXT_WORD
+          Move to next word.
+
+   REQ_PREV_WORD
+          Move to previous word.
+
+   REQ_BEG_FIELD
+          Move to beginning of field.
+
+   REQ_END_FIELD
+          Move to end of field.
+
+   REQ_BEG_LINE
+          Move to beginning of line.
+
+   REQ_END_LINE
+          Move to end of line.
+
+   REQ_LEFT_CHAR
+          Move left in field.
+
+   REQ_RIGHT_CHAR
+          Move right in field.
+
+   REQ_UP_CHAR
+          Move up in field.
+
+   REQ_DOWN_CHAR
+          Move down in field.
+
+   Each  word  is  separated  from  the  previous  and next characters by
+   whitespace. The commands to move to beginning and end of line or field
+   look for the first or last non-pad character in their ranges.
+
+    Scrolling Requests
+
+   Fields  that  are dynamic and have grown and fields explicitly created
+   with   offscreen   rows   are   scrollable.   One-line  fields  scroll
+   horizontally;  multi-line  fields scroll vertically. Most scrolling is
+   triggered by editing and intra-field movement (the library scrolls the
+   field  to  keep  the  cursor  visible).  It  is possible to explicitly
+   request scrolling with the following requests:
+
+   REQ_SCR_FLINE
+          Scroll vertically forward a line.
+
+   REQ_SCR_BLINE
+          Scroll vertically backward a line.
+
+   REQ_SCR_FPAGE
+          Scroll vertically forward a page.
+
+   REQ_SCR_BPAGE
+          Scroll vertically backward a page.
+
+   REQ_SCR_FHPAGE
+          Scroll vertically forward half a page.
+
+   REQ_SCR_BHPAGE
+          Scroll vertically backward half a page.
+
+   REQ_SCR_FCHAR
+          Scroll horizontally forward a character.
+
+   REQ_SCR_BCHAR
+          Scroll horizontally backward a character.
+
+   REQ_SCR_HFLINE
+          Scroll horizontally one field width forward.
+
+   REQ_SCR_HBLINE
+          Scroll horizontally one field width backward.
+
+   REQ_SCR_HFHALF
+          Scroll horizontally one half field width forward.
+
+   REQ_SCR_HBHALF
+          Scroll horizontally one half field width backward.
+
+   For scrolling purposes, a page of a field is the height of its visible
+   part.
+
+    Editing Requests
+
+   When  you pass the forms driver an ASCII character, it is treated as a
+   request  to add the character to the field's data buffer. Whether this
+   is  an  insertion  or  a  replacement depends on the field's edit mode
+   (insertion is the default.
+
+   The following requests support editing the field and changing the edit
+   mode:
+
+   REQ_INS_MODE
+          Set insertion mode.
+
+   REQ_OVL_MODE
+          Set overlay mode.
+
+   REQ_NEW_LINE
+          New line request (see below for explanation).
+
+   REQ_INS_CHAR
+          Insert space at character location.
+
+   REQ_INS_LINE
+          Insert blank line at character location.
+
+   REQ_DEL_CHAR
+          Delete character at cursor.
+
+   REQ_DEL_PREV
+          Delete previous word at cursor.
+
+   REQ_DEL_LINE
+          Delete line at cursor.
+
+   REQ_DEL_WORD
+          Delete word at cursor.
+
+   REQ_CLR_EOL
+          Clear to end of line.
+
+   REQ_CLR_EOF
+          Clear to end of field.
+
+   REQ_CLEAR_FIELD
+          Clear entire field.
+
+   The   behavior  of  the  REQ_NEW_LINE  and  REQ_DEL_PREV  requests  is
+   complicated  and  partly  controlled  by  a pair of forms options. The
+   special  cases  are triggered when the cursor is at the beginning of a
+   field, or on the last line of the field.
+
+   First, we consider REQ_NEW_LINE:
+
+   The  normal  behavior  of  REQ_NEW_LINE in insert mode is to break the
+   current line at the position of the edit cursor, inserting the portion
+   of  the  current  line  after  the  cursor as a new line following the
+   current  and  moving the cursor to the beginning of that new line (you
+   may think of this as inserting a newline in the field buffer).
+
+   The  normal  behavior  of REQ_NEW_LINE in overlay mode is to clear the
+   current  line from the position of the edit cursor to end of line. The
+   cursor is then moved to the beginning of the next line.
+
+   However, REQ_NEW_LINE at the beginning of a field, or on the last line
+   of  a  field,  instead  does a REQ_NEXT_FIELD. O_NL_OVERLOAD option is
+   off, this special action is disabled.
+
+   Now, let us consider REQ_DEL_PREV:
+
+   The  normal  behavior  of  REQ_DEL_PREV  is  to  delete  the  previous
+   character.  If  insert mode is on, and the cursor is at the start of a
+   line,  and  the  text  on  that  line will fit on the previous one, it
+   instead  appends  the contents of the current line to the previous one
+   and  deletes  the  current  line  (you may think of this as deleting a
+   newline from the field buffer).
+
+   However,  REQ_DEL_PREV  at the beginning of a field is instead treated
+   as a REQ_PREV_FIELD.
+
+   If  the  O_BS_OVERLOAD  option is off, this special action is disabled
+   and the forms driver just returns E_REQUEST_DENIED.
+
+   See  Form  Options for discussion of how to set and clear the overload
+   options.
+
+    Order Requests
+
+   If the type of your field is ordered, and has associated functions for
+   getting  the  next and previous values of the type from a given value,
+   there are requests that can fetch that value into the field buffer:
+
+   REQ_NEXT_CHOICE
+          Place the successor value of the current value in the buffer.
+
+   REQ_PREV_CHOICE
+          Place the predecessor value of the current value in the buffer.
+
+   Of the built-in field types, only TYPE_ENUM has built-in successor and
+   predecessor  functions.  When you define a field type of your own (see
+   Custom   Validation   Types),  you  can  associate  our  own  ordering
+   functions.
+
+    Application Commands
+
+   Form  requests  are  represented  as  integers  above the curses value
+   greater   than  KEY_MAX  and  less  than  or  equal  to  the  constant
+   MAX_COMMAND.  If  your  input-virtualization  routine  returns a value
+   above MAX_COMMAND, the forms driver will ignore it.
+
+  Field Change Hooks
+
+   It  is  possible  to  set  function  hooks to be executed whenever the
+   current  field  or  form  changes. Here are the functions that support
+   this:
+typedef void    (*HOOK)();       /* pointer to function returning void */
+
+int set_form_init(FORM *form,    /* form to alter */
+                  HOOK hook);    /* initialization hook */
+
+HOOK form_init(FORM *form);      /* form to query */
+
+int set_form_term(FORM *form,    /* form to alter */
+                  HOOK hook);    /* termination hook */
+
+HOOK form_term(FORM *form);      /* form to query */
+
+int set_field_init(FORM *form,   /* form to alter */
+                  HOOK hook);    /* initialization hook */
+
+HOOK field_init(FORM *form);     /* form to query */
+
+int set_field_term(FORM *form,   /* form to alter */
+                  HOOK hook);    /* termination hook */
+
+HOOK field_term(FORM *form);     /* form to query */
+
+   These functions allow you to either set or query four different hooks.
+   In  each  of  the  set  functions,  the  second argument should be the
+   address  of a hook function. These functions differ only in the timing
+   of the hook call.
+
+   form_init
+          This  hook  is called when the form is posted; also, just after
+          each page change operation.
+
+   field_init
+          This  hook  is called when the form is posted; also, just after
+          each field change
+
+   field_term
+          This  hook is called just after field validation; that is, just
+          before the field is altered. It is also called when the form is
+          unposted.
+
+   form_term
+          This  hook  is  called  when  the  form is unposted; also, just
+          before each page change operation.
+
+   Calls to these hooks may be triggered
+    1. When user editing requests are processed by the forms driver
+    2. When the current page is changed by set_current_field() call
+    3. When the current field is changed by a set_form_page() call
+
+   See Field Change Commands for discussion of the latter two cases.
+
+   You  can  set  a default hook for all fields by passing one of the set
+   functions a NULL first argument.
+
+   You  can  disable  any of these hooks by (re)setting them to NULL, the
+   default value.
+
+  Field Change Commands
+
+   Normally,  navigation  through  the  form will be driven by the user's
+   input  requests.  But  sometimes  it  is useful to be able to move the
+   focus  for  editing  and viewing under control of your application, or
+   ask  which  field it currently is in. The following functions help you
+   accomplish this:
+int set_current_field(FORM *form,         /* form to alter */
+                      FIELD *field);      /* field to shift to */
+
+FIELD *current_field(FORM *form);         /* form to query */
+
+int field_index(FORM *form,               /* form to query */
+                FIELD *field);            /* field to get index of */
+
+   The function field_index() returns the index of the given field in the
+   given   form's   field  array  (the  array  passed  to  new_form()  or
+   set_form_fields()).
+
+   The  initial  current field of a form is the first active field on the
+   first page. The function set_form_fields() resets this.
+
+   It is also possible to move around by pages.
+int set_form_page(FORM *form,             /* form to alter */
+                  int page);              /* page to go to (0-origin) */
+
+int form_page(FORM *form);                /* return form's current page */
+
+   The   initial  page  of  a  newly-created  form  is  0.  The  function
+   set_form_fields() resets this.
+
+  Form Options
+
+   Like  fields,  forms may have control option bits. They can be changed
+   or queried with these functions:
+int set_form_opts(FORM *form,             /* form to alter */
+                  int attr);              /* attribute to set */
+
+int form_opts_on(FORM *form,              /* form to alter */
+                 int attr);               /* attributes to turn on */
+
+int form_opts_off(FORM *form,             /* form to alter */
+                  int attr);              /* attributes to turn off */
+
+int form_opts(FORM *form);                /* form to query */
+
+   By default, all options are on. Here are the available option bits:
+
+   O_NL_OVERLOAD
+          Enable  overloading  of  REQ_NEW_LINE  as  described in Editing
+          Requests. The value of this option is ignored on dynamic fields
+          that  have  not  reached  their  size limit; these have no last
+          line,  so  the  circumstances  for  triggering a REQ_NEXT_FIELD
+          never arise.
+
+   O_BS_OVERLOAD
+          Enable  overloading  of  REQ_DEL_PREV  as  described in Editing
+          Requests.
+
+   The option values are bit-masks and can be composed with logical-or in
+   the obvious way.
+
+  Custom Validation Types
+
+   The  form library gives you the capability to define custom validation
+   types  of  your  own.  Further,  the  optional additional arguments of
+   set_field_type effectively allow you to parameterize validation types.
+   Most  of the complications in the validation-type interface have to do
+   with the handling of the additional arguments within custom validation
+   functions.
+
+    Union Types
+
+   The  simplest  way  to create a custom data type is to compose it from
+   two preexisting ones:
+FIELD *link_fieldtype(FIELDTYPE *type1,
+                      FIELDTYPE *type2);
+
+   This  function creates a field type that will accept any of the values
+   legal  for  either  of  its  argument field types (which may be either
+   predefined  or  programmer-defined).  If a set_field_type() call later
+   requires  arguments,  the new composite type expects all arguments for
+   the  first  type,  than  all arguments for the second. Order functions
+   (see  Order Requests) associated with the component types will work on
+   the  composite;  what it does is check the validation function for the
+   first  type,  then  for  the  second,  to  figure what type the buffer
+   contents should be treated as.
+
+    New Field Types
+
+   To  create  a field type from scratch, you need to specify one or both
+   of the following things:
+     * A  character-validation function, to check each character as it is
+       entered.
+     * A field-validation function to be applied on exit from the field.
+
+   Here is how you do that:
+typedef int     (*HOOK)();       /* pointer to function returning int */
+
+FIELDTYPE *new_fieldtype(HOOK f_validate, /* field validator */
+                         HOOK c_validate) /* character validator */
+
+int free_fieldtype(FIELDTYPE *ftype);     /* type to free */
+
+   At least one of the arguments of new_fieldtype() must be non-NULL. The
+   forms  driver  will  automatically  call  the  new  type's  validation
+   functions at appropriate points in processing a field of the new type.
+
+   The  function  free_fieldtype()  deallocates  the  argument fieldtype,
+   freeing all storage associated with it.
+
+   Normally,  a field validator is called when the user attempts to leave
+   the  field.  Its  first argument is a field pointer, from which it can
+   get  to  field buffer 0 and test it. If the function returns TRUE, the
+   operation  succeeds; if it returns FALSE, the edit cursor stays in the
+   field.
+
+   A  character  validator  gets  the  character  passed  in  as  a first
+   argument.  It  too should return TRUE if the character is valid, FALSE
+   otherwise.
+
+    Validation Function Arguments
+
+   Your  field-  and  character-  validation  functions  will be passed a
+   second  argument  as  well.  This  second argument is the address of a
+   structure  (which  we  will  call  a  pile)  built  from  any  of  the
+   field-type-specific  arguments  passed to set_field_type(). If no such
+   arguments  are  defined for the field type, this pile pointer argument
+   will be NULL.
+
+   In order to arrange for such arguments to be passed to your validation
+   functions,  you  must  associate  a  small  set  of storage-management
+   functions with the type. The forms driver will use these to synthesize
+   a  pile from the trailing arguments of each set_field_type() argument,
+   and a pointer to the pile will be passed to the validation functions.
+
+   Here is how you make the association:
+typedef char    *(*PTRHOOK)();    /* pointer to function returning (char *) */
+typedef void    (*VOIDHOOK)();    /* pointer to function returning void */
+
+int set_fieldtype_arg(FIELDTYPE *type,    /* type to alter */
+                      PTRHOOK make_str,   /* make structure from args */
+                      PTRHOOK copy_str,   /* make copy of structure */
+                      VOIDHOOK free_str); /* free structure storage */
+
+   Here is how the storage-management hooks are used:
+
+   make_str
+          This  function  is  called  by  set_field_type().  It  gets one
+          argument,  a  va_list  of the type-specific arguments passed to
+          set_field_type().  It is expected to return a pile pointer to a
+          data structure that encapsulates those arguments.
+
+   copy_str
+          This function is called by form library functions that allocate
+          new  field  instances.  It  is expected to take a pile pointer,
+          copy  the  pile to allocated storage, and return the address of
+          the pile copy.
+
+   free_str
+          This   function  is  called  by  field-  and  type-deallocation
+          routines  in the library. It takes a pile pointer argument, and
+          is expected to free the storage of that pile.
+
+   The  make_str  and  copy_str  functions  may  return  NULL  to  signal
+   allocation  failure.  The  library  routines  will that call them will
+   return  error  indication  when  this  happens.  Thus, your validation
+   functions  should  never  see  a  NULL file pointer and need not check
+   specially for it.
+
+    Order Functions For Custom Types
+
+   Some  custom  field  types are simply ordered in the same well-defined
+   way  that  TYPE_ENUM  is.  For  such  types,  it is possible to define
+   successor and predecessor functions to support the REQ_NEXT_CHOICE and
+   REQ_PREV_CHOICE requests. Here is how:
+typedef int     (*INTHOOK)();     /* pointer to function returning int */
+
+int set_fieldtype_arg(FIELDTYPE *type,    /* type to alter */
+                      INTHOOK succ,       /* get successor value */
+                      INTHOOK pred);      /* get predecessor value */
+
+   The  successor  and  predecessor  arguments  will  each  be passed two
+   arguments;  a field pointer, and a pile pointer (as for the validation
+   functions).  They  are  expected to use the function field_buffer() to
+   read  the current value, and set_field_buffer() on buffer 0 to set the
+   next  or  previous  value.  Either  hook  may  return TRUE to indicate
+   success  (a legal next or previous value was set) or FALSE to indicate
+   failure.
+
+    Avoiding Problems
+
+   The  interface  for  defining  custom types is complicated and tricky.
+   Rather  than attempting to create a custom type entirely from scratch,
+   you  should start by studying the library source code for whichever of
+   the pre-defined types seems to be closest to what you want.
+
+   Use  that code as a model, and evolve it towards what you really want.
+   You  will avoid many problems and annoyances that way. The code in the
+   ncurses  library  has  been  specifically  exempted  from  the package
+   copyright to support this.
+
+   If  your  custom  type  defines  order  functions,  have  do something
+   intuitive  with  a  blank  field.  A  useful convention is to make the
+   successor   of  a  blank  field  the  types  minimum  value,  and  its
+   predecessor the maximum.

+This is a clone of the form library that is available with typical
+System V curses implementations (ETI).
+
+It is modelled after the documentation that comes for this library with
+a 386 based SVR4 implementation (ESIX).
+
+The development environment was and is an ELF based Linux system.
+
+For things that still need doing, see the TO-DO file in the top-level

+/*----------------------------------------------------------------------------
+  This is the core module of the form library. It contains the majority
+  of the driver routines as well as the form_driver function.
+
+  Essentially this module is nearly the whole library. This is because
+  all the functions in this module depends on some others in the module,
+  so it makes no sense to split them into separate files because they
+  will always be linked together. The only acceptable concern is turnaround
+  time for this module, but now we have all Pentiums or RISCs, so what!
+
+  The driver routines are grouped into nine generic categories:
+
+   a)   Page Navigation            ( all functions prefixed by PN_ )
+        The current page of the form is left and some new page is
+        entered.
+   b)   Inter-Field Navigation     ( all functions prefixed by FN_ )
+        The current field of the form is left and some new field is
+        entered.
+   c)   Intra-Field Navigation     ( all functions prefixed by IFN_ )
+        The current position in the current field is changed.
+   d)   Vertical Scrolling         ( all functions prefixed by VSC_ )
+        Essentially this is a specialization of Intra-Field navigation.
+        It has to check for a multi-line field.
+   e)   Horizontal Scrolling       ( all functions prefixed by HSC_ )
+        Essentially this is a specialization of Intra-Field navigation.
+        It has to check for a single-line field.
+   f)   Field Editing              ( all functions prefixed by FE_ )
+        The content of the current field is changed
+   g)   Edit Mode requests         ( all functions prefixed by EM_ )
+        Switching between insert and overlay mode
+   h)   Field-Validation requests  ( all functions prefixed by FV_ )
+        Perform verifications of the field.
+   i)   Choice requests            ( all functions prefixed by CR_ )
+        Requests to enumerate possible field values

+Some options that may effect compatibility in behavior to SVr4 forms,

+
+The initial implementation tries to stay very close with the behavior
+of the original SVr4 implementation, although in some areas it is quite
+clear that this isn't the most appropriate way. As far as possible this
+sources will allow you to build a forms lib that behaves quite similar
+to SVr4, but now and in the future we will give you better options.
+Perhaps at some time we will make this configurable at runtime.

+ * This is not a full implementation of a field type, but adds some
+ * support for higher level languages with some restrictions to interop
+ * with C language. In particular, the collection of arguments for the
+ * various fieldtypes is not based on the vararg C mechanism, but on a
+ * iterator based callback mechanism that allows the high level language
+ * to provide the arguments as a structure. Most languages have mechanisms
+ * to layout structures so that they can be passed to C.
+ *
+ * The languages can register a new generic fieldtype dynamically and store
+ * a handle (key) to the calling object as an argument. Together with that
+ * it can register a freearg callback, so that the high level language
+ * remains in control of the memory management of the arguments they pass.
+ * The design idea is, that the high-level language - typically a OO
+ * language like C# or Java, uses its own dispatching mechanisms
+ * (polymorphism) to call the proper check routines responsible for the
+ * argument type. So these language implement typically only one generic
+ * fieldtype they register with the forms library using this call.
+ *
+ * For that purpose we have extended the fieldtype structure by a new element
+ * that gets the arguments from a single struct passed by the caller.

+#
+# This is the master termcap/terminfo capability table.
+#
+# This table is used to generate initializers for tables that drive tic,
+# infocmp, and the library compilation code used to support the termcap
+# compatibility hack.  It is also used to generate the tabular portion of the
+# terminfo(5) man page; lines beginning with `#%' are passed through to become
+# the terminfo table.
+#
+# This file has three major sections; a standard-capabilities table, two
+# extension-capability tables, and a section of aliases declarations.
+# The first two have the same format, as follows:
+#
+# FILE FORMAT
+#
+# Column 1: terminfo variable name
+# Column 2: terminfo capability name
+# Column 3: capability type (boolean, numeric, or string)
+# Column 4: termcap capability name
+# Column 5: KEY_xxx name, if any, `-' otherwise
+# Column 6: value for KEY_xxx name, if any, `-' otherwise
+# Column 7: Lead with `Y' if capability should be emitted in termcap
+#           translations, `-' otherwise
+# Column 8: capability description
+#
+# The codes following [Y-] in column 7 describe the versions of termcap which
+# use the given capability.  This information is not used by the curses library
+# proper; rather, it is there to help the terminfo maintainer avoid emitting
+# termcap entry translations that are more than 1023 bytes long (and tank a
+# lot of old termcap-using programs).  The codes read as follows:
+#	B = mentioned in the BSD man page for 4.4BSD curses
+#	C = used by the 4.4BSD curses library
+#	G = mentioned in the documentation for GNU termcap
+#	E = used by GNU Emacs
+#	K = remove this terminfo capability when translating to standard format
+# The important codes are C and E.  A cap with C or E should be preserved in
+# translation if possible.  The problem is that preserving all such caps may
+# lead to some termcap translations being too long.  The termcap maintainer
+# has a bit of a juggling act to do...potential problem cases are marked with
+# an asterisk (*).
+#
+# The aliases section has the following format:
+#
+# Column 1: either `capalias' or `infoalias'
+# Column 2: name to be aliased
+# Column 3: what name it should translate to.  The name IGNORE means it
+#           should be discarded with a warning message.
+# Column 4: name of the extension set (used for compiler warning messages)
+# Column 5: capability description (usually an associated terminfo variable)
+#
+# HANDLING TERMCAP AND TERMINFO EXTENSIONS
+#
+# There are basically five different ways to handle termcap and terminfo
+# extensions:
+#
+# 1. Don't list the capname here, or list it but comment it out (the latter
+# is preferable; someone might want to handle it in the future).  If you do
+# this, the capability will be treated as unknown and raise a warning from
+# the compiler.
+#
+# 2. Alias it.  This is appropriate if the capability has the same meaning
+# as an already-supported one.  The compiler will handle aliasing, emitting
+# an appropriate informational message whenever an alias fires.
+#
+# 3. List it in the standard table.  You almost certainly do *not* want
+# to do this -- the capabilities in that one, and their order, have been
+# carefully chosen to be SVr4-binary-compatible when they're written out
+# as a terminfo object, and breaking this would be bad.  It is up to the ncurses
+# library what to do with the terminfo data after it is read in.
+#
+# 4. List it in the aliases table with an IGNORE target field.  If you
+# do this, the capability will be ignored on input (though the user will
+# get a warning message about it).
+#
+# 5. List it in the extensions table. If you do this, the compiler will
+# silently accept the capability, but the curses library proper will never
+# see it (because it won't be written out as part of the terminfo object
+# format).  It is up to you what you have the compiler do with it.
+#
+# There are two opposite reasons to choose option 5.  One is when you want
+# to eat the capability silently and discard it when doing translations
+# to terminfo with tic -I.  Some very old obsolete BSD caps like :kn: are
+# in this class.  Nothing will ever use them again.
+#
+# More usually, you want the compiler to try to deduce something from the
+# capability value that it can use to translate it into your output format.
+# You'll need to write custom code, probably in postprocess_termcap() or
+# postprocess_terminfo(), to handle the translation.
+#
+# CONTROLLING ENTRY LENGTH
+#
+# Notes on specific elisions made to fit translations within 1023 bytes:
+#
+# Machines with IBM PC-like keyboards want to be able to define the following
+# keys: key_npage, key_ppage, key_home, key_ll (which is used for in termcap-
+# only environments for End or Home-Down), key_dc, and key_ic.  This is also
+# the set of keys the `joe' editor will be upset if it can't see.  So don't
+# trim those out of the set to be translated to termcap, or various users of
+# the termcap file will become irate.
+#
+# It might look tempting to leave those long init strings out of translations.
+# We can't do it (yet); 4.4BSD tput and tset use them.
+#
+# We retain the sgr capability in translation in spite of the fact that neither
+# 4.4BSD nor GNU Emacs uses it, because (a) some entry naming distinctions are
+# hard to understand without it, and (b) the entries in which it is long tend
+# to be older types that don't use up a lot of string space on function keys.
+# The tic(1) translation code will complain and elide it if it makes a critical
+# difference (there is special code in tic to recognize this situation).
+#
+# Yes, BSD tset(1) uses hpa.  We elide hpa/vpa anyway because the motion
+# optimizer in BSD curses didn't use them.  This omission seems to be the
+# single most effective one, it shortened the resolved length of all thirteen
+# problem entries in the 9.9.0 version of the terminfo master below critical.
+#
+# It would be nice to keep f11 and f12 for Emacs use, but a couple of termcap
+# translations go back over critical if we do this.  As 4.4BSD curses fades
+# into history and GNU termcap's application base shrinks towards being GNU
+# Emacs only, we'll probably elide out some BSD-only capabilities in order
+# to buy space for non-essentials Emacs is still using.  Capabilities high
+# on that hit list: rc, sc, uc.

+#############################################################################
+#
+# STANDARD CAPABILITIES
+#
+#%The following is a complete table of the capabilities included in a
+#%terminfo description block and available to terminfo-using code.  In each
+#%line of the table,
+#%
+#%The \fBvariable\fR is the name by which the programmer (at the terminfo level)
+#%accesses the capability.
+#%
+#%The \fBcapname\fR is the short name used in the text of the database,
+#%and is used by a person updating the database.
+#%Whenever possible, capnames are chosen to be the same as or similar to
+#%the ANSI X3.64-1979 standard (now superseded by ECMA-48, which uses
+#%identical or very similar names).  Semantics are also intended to match
+#%those of the specification.
+#%
+#%The termcap code is the old
+#%.B termcap
+#%capability name (some capabilities are new, and have names which termcap
+#%did not originate).
+#%.P
+#%Capability names have no hard length limit, but an informal limit of 5
+#%characters has been adopted to keep them short and to allow the tabs in
+#%the source file
+#%.B Caps
+#%to line up nicely.
+#%
+#%Finally, the description field attempts to convey the semantics of the
+#%capability.  You may find some codes in the description field:
+#%.TP
+#%(P)
+#%indicates that padding may be specified
+#%.TP
+#%#[1-9]
+#%in the description field indicates that the string is passed
+#%through \fBtparm\fP(3X) with parameters as given (#\fIi\fP).
+#%.IP
+#%If no parameters are listed in the description,
+#%passing the string through \fBtparm\fP(3X) may give unexpected results,
+#%e.g., if it contains percent (%%) signs.
+#%.TP
+#%(P*)
+#%indicates that padding may vary in proportion to the number of
+#%lines affected
+#%.TP
+#%(#\d\fIi\fP\u)
+#%indicates the \fIi\fP\uth\d parameter.

+# TERMCAP EXTENSION CAPABILITIES
+#
+# The capabilities below are either obsolete or extensions on certain systems.
+# They are not used by SVR4 terminfo.  Some are used by captoinfo to translate
+# termcap sources; the rest are listed for completeness, and in case somebody
+# cares about them enough to hack in code that will translate them into
+# terminfo capabilities.
+#
+# The first part of the list is from Ross Ridge's `mytinfo' package
+# (comp.sources.unix, volume 26); the variable names and terminfo names (as
+# well as the termcap codes) match his list.
+#
+# This group of codes is not marked obsolete in 4.4BSD, but have no direct
+# terminfo equivalents.  The rs capability is specially translated to terminfo
+# r2, and vice versa, if an entry does not already have an r2.  Similarly,
+# i2 is translated to r3 if there is no r3 (because SV terminfo maps is to i2).
+# The ug capability is thrown away, but assumed to be whatever sg is if the
+# latter is nonzero and we're dumping in termcap format.

+# The `kn' code is accepted but ignored.
+#
+# The `ma' capability was a 4.0BSD feature used by vi version 2.

+#
+# This is an adaptation of ncurses' termcap/terminfo capability table, which
+# is designed to align with AIX 4.x's terminfo.
+#
+# This table is used to generate initializers for tables that drive tic,
+# infocmp, and the library compilation code used to support the termcap
+# compatibility hack.  It is also used to generate the tabular portion of the
+# terminfo(5) man page; lines beginning with `#%' are passed through to become
+# the terminfo table.
+#
+# This file has three major sections; a standard-capabilities table, two
+# extension-capability tables, and a section of aliases declarations.
+# The first two have the same format, as follows:
+#
+# FILE FORMAT
+#
+# Column 1: terminfo variable name
+# Column 2: terminfo capability name
+# Column 3: capability type (boolean, numeric, or string)
+# Column 4: termcap capability name
+# Column 5: KEY_xxx name, if any, `-' otherwise
+# Column 6: value for KEY_xxx name, if any, `-' otherwise
+# Column 7: Lead with `Y' if capability should be emitted in termcap
+#           translations, `-' otherwise
+# Column 8: capability description
+#
+# The codes following [Y-] in column 7 describe the versions of termcap which
+# use the given capability.  This information is not used by the curses library
+# proper; rather, it is there to help the terminfo maintainer avoid emitting
+# termcap entry translations that are more than 1023 bytes long (and tank a
+# lot of old termcap-using programs).  The codes read as follows:
+#	B = mentioned in the BSD man page for 4.4BSD curses
+#	C = used by the 4.4BSD curses library
+#	G = mentioned in the documentation for GNU termcap
+#	E = used by GNU Emacs
+#	K = remove this terminfo capability when translating to standard format
+# The important codes are C and E.  A cap with C or E should be preserved in
+# translation if possible.  The problem is that preserving all such caps may
+# lead to some termcap translations being too long.  The termcap maintainer
+# has a bit of a juggling act to do...potential problem cases are marked with
+# an asterisk (*).
+#
+# The aliases section has the following format:
+#
+# Column 1: either `capalias' or `infoalias'
+# Column 2: name to be aliased
+# Column 3: what name it should translate to.  The name IGNORE means it
+#           should be discarded with a warning message.
+# Column 4: name of the extension set (used for compiler warning messages)
+# Column 5: capability description (usually an associated terminfo variable)
+#
+# HANDLING TERMCAP AND TERMINFO EXTENSIONS
+#
+# There are basically five different ways to handle termcap and terminfo
+# extensions:
+#
+# 1. Don't list the capname here, or list it but comment it out (the latter
+# is preferable; someone might want to handle it in the future).  If you do
+# this, the capability will be treated as unknown and raise a warning from
+# the compiler.
+#
+# 2. Alias it.  This is appropriate if the capability has the same meaning
+# as an already-supported one.  The compiler will handle aliasing, emitting
+# an appropriate informational message whenever an alias fires.
+#
+# 3. List it in the standard table.  You almost certainly do *not* want
+# to do this -- the capabilities in that one, and their order, have been
+# carefully chosen to be SVr4-binary-compatible when they're written out
+# as a terminfo object, and breaking this would be bad.  It is up to the ncurses
+# library what to do with the terminfo data after it is read in.
+#
+# 4. List it in the aliases table with an IGNORE target field.  If you
+# do this, the capability will be ignored on input (though the user will
+# get a warning message about it).
+#
+# 5. List it in the extensions table. If you do this, the compiler will
+# silently accept the capability, but the curses library proper will never
+# see it (because it won't be written out as part of the terminfo object
+# format).  It is up to you what you have the compiler do with it.
+#
+# There are two opposite reasons to choose option 5.  One is when you want
+# to eat the capability silently and discard it when doing translations
+# to terminfo with tic -I.  Some very old obsolete BSD caps like :kn: are
+# in this class.  Nothing will ever use them again.
+#
+# More usually, you want the compiler to try to deduce something from the
+# capability value that it can use to translate it into your output format.
+# You'll need to write custom code, probably in postprocess_termcap() or
+# postprocess_terminfo(), to handle the translation.
+#
+# CONTROLLING ENTRY LENGTH
+#
+# Notes on specific elisions made to fit translations within 1023 bytes:
+#
+# Machines with IBM PC-like keyboards want to be able to define the following
+# keys: key_npage, key_ppage, key_home, key_ll (which is used for in termcap-
+# only environments for End or Home-Down), key_dc, and key_ic.  This is also
+# the set of keys the `joe' editor will be upset if it can't see.  So don't
+# trim those out of the set to be translated to termcap, or various users of
+# the termcap file will become irate.
+#
+# It might look tempting to leave those long init strings out of translations.
+# We can't do it (yet); 4.4BSD tput and tset use them.
+#
+# We retain the sgr capability in translation in spite of the fact that neither
+# 4.4BSD nor GNU Emacs uses it, because (a) some entry naming distinctions are
+# hard to understand without it, and (b) the entries in which it is long tend
+# to be older types that don't use up a lot of string space on function keys.
+# The tic(1) translation code will complain and elide it if it makes a critical
+# difference (there is special code in tic to recognize this situation).
+#
+# Yes, BSD tset(1) uses hpa.  We elide hpa/vpa anyway because the motion
+# optimizer in BSD curses didn't use them.  This omission seems to be the
+# single most effective one, it shortened the resolved length of all thirteen
+# problem entries in the 9.9.0 version of the terminfo master below critical.
+#
+# It would be nice to keep f11 and f12 for Emacs use, but a couple of termcap
+# translations go back over critical if we do this.  As 4.4BSD curses fades
+# into history and GNU termcap's application base shrinks towards being GNU
+# Emacs only, we'll probably elide out some BSD-only capabilities in order
+# to buy space for non-essentials Emacs is still using.  Capabilities high
+# on that hit list: rc, sc, uc.

+# STANDARD CAPABILITIES
+#
+#%The following is a complete table of the capabilities included in a
+#%terminfo description block and available to terminfo-using code.  In each
+#%line of the table,
+#%
+#%The \fBvariable\fR is the name by which the programmer (at the terminfo level)
+#%accesses the capability.
+#%
+#%The \fBcapname\fR is the short name used in the text of the database,
+#%and is used by a person updating the database.
+#%Whenever possible, capnames are chosen to be the same as or similar to
+#%the ANSI X3.64-1979 standard (now superseded by ECMA-48, which uses
+#%identical or very similar names).  Semantics are also intended to match
+#%those of the specification.
+#%
+#%The termcap code is the old
+#%.B termcap
+#%capability name (some capabilities are new, and have names which termcap
+#%did not originate).
+#%.P
+#%Capability names have no hard length limit, but an informal limit of 5
+#%characters has been adopted to keep them short and to allow the tabs in
+#%the source file
+#%.B Caps
+#%to line up nicely.
+#%
+#%Finally, the description field attempts to convey the semantics of the
+#%capability.  You may find some codes in the description field:
+#%.TP
+#%(P)
+#%indicates that padding may be specified
+#%.TP
+#%#[1-9]
+#%in the description field indicates that the string is passed
+#%through \fBtparm\fP(3X) with parameters as given (#\fIi\fP).
+#%.IP
+#%If no parameters are listed in the description,
+#%passing the string through \fBtparm\fP(3X) may give unexpected results,
+#%e.g., if it contains percent (%%) signs.
+#%.TP
+#%(P*)
+#%indicates that padding may vary in proportion to the number of
+#%lines affected
+#%.TP
+#%(#\d\fIi\fP\u)
+#%indicates the \fIi\fP\uth\d parameter.

+# TERMCAP EXTENSION CAPABILITIES
+#
+# The capabilities below are either obsolete or extensions on certain systems.
+# They are not used by SVR4 terminfo.  Some are used by captoinfo to translate
+# termcap sources; the rest are listed for completeness, and in case somebody
+# cares about them enough to hack in code that will translate them into
+# terminfo capabilities.
+#
+# The first part of the list is from Ross Ridge's `mytinfo' package
+# (comp.sources.unix, volume 26); the variable names and terminfo names (as
+# well as the termcap codes) match his list.
+#
+# This group of codes is not marked obsolete in 4.4BSD, but have no direct
+# terminfo equivalents.  The rs capability is specially translated to terminfo
+# r2, and vice versa, if an entry does not already have an r2.  Similarly,
+# i2 is translated to r3 if there is no r3 (because SV terminfo maps is to i2).
+# The ug capability is thrown away, but assumed to be whatever sg is if the
+# latter is nonzero and we're dumping in termcap format.

+#
+# This is an adaptation of ncurses' termcap/terminfo capability table, which
+# is designed to align with HPUX 11.x's terminfo.
+#
+# This table is used to generate initializers for tables that drive tic,
+# infocmp, and the library compilation code used to support the termcap
+# compatibility hack.  It is also used to generate the tabular portion of the
+# terminfo(5) man page; lines beginning with `#%' are passed through to become
+# the terminfo table.
+#
+# This file has three major sections; a standard-capabilities table, two
+# extension-capability tables, and a section of aliases declarations.
+# The first two have the same format, as follows:
+#
+# FILE FORMAT
+#
+# Column 1: terminfo variable name
+# Column 2: terminfo capability name
+# Column 3: capability type (boolean, numeric, or string)
+# Column 4: termcap capability name
+# Column 5: KEY_xxx name, if any, `-' otherwise
+# Column 6: value for KEY_xxx name, if any, `-' otherwise
+# Column 7: Lead with `Y' if capability should be emitted in termcap
+#           translations, `-' otherwise
+# Column 8: capability description
+#
+# The codes following [Y-] in column 7 describe the versions of termcap which
+# use the given capability.  This information is not used by the curses library
+# proper; rather, it is there to help the terminfo maintainer avoid emitting
+# termcap entry translations that are more than 1023 bytes long (and tank a
+# lot of old termcap-using programs).  The codes read as follows:
+#	B = mentioned in the BSD man page for 4.4BSD curses
+#	C = used by the 4.4BSD curses library
+#	G = mentioned in the documentation for GNU termcap
+#	E = used by GNU Emacs
+#	K = remove this terminfo capability when translating to standard format
+# The important codes are C and E.  A cap with C or E should be preserved in
+# translation if possible.  The problem is that preserving all such caps may
+# lead to some termcap translations being too long.  The termcap maintainer
+# has a bit of a juggling act to do...potential problem cases are marked with
+# an asterisk (*).
+#
+# The aliases section has the following format:
+#
+# Column 1: either `capalias' or `infoalias'
+# Column 2: name to be aliased
+# Column 3: what name it should translate to.  The name IGNORE means it
+#           should be discarded with a warning message.
+# Column 4: name of the extension set (used for compiler warning messages)
+# Column 5: capability description (usually an associated terminfo variable)
+#
+# HANDLING TERMCAP AND TERMINFO EXTENSIONS
+#
+# There are basically five different ways to handle termcap and terminfo
+# extensions:
+#
+# 1. Don't list the capname here, or list it but comment it out (the latter
+# is preferable; someone might want to handle it in the future).  If you do
+# this, the capability will be treated as unknown and raise a warning from
+# the compiler.
+#
+# 2. Alias it.  This is appropriate if the capability has the same meaning
+# as an already-supported one.  The compiler will handle aliasing, emitting
+# an appropriate informational message whenever an alias fires.
+#
+# 3. List it in the standard table.  You almost certainly do *not* want
+# to do this -- the capabilities in that one, and their order, have been
+# carefully chosen to be SVr4-binary-compatible when they're written out
+# as a terminfo object, and breaking this would be bad.  It is up to the ncurses
+# library what to do with the terminfo data after it is read in.
+#
+# 4. List it in the aliases table with an IGNORE target field.  If you
+# do this, the capability will be ignored on input (though the user will
+# get a warning message about it).
+#
+# 5. List it in the extensions table. If you do this, the compiler will
+# silently accept the capability, but the curses library proper will never
+# see it (because it won't be written out as part of the terminfo object
+# format).  It is up to you what you have the compiler do with it.
+#
+# There are two opposite reasons to choose option 5.  One is when you want
+# to eat the capability silently and discard it when doing translations
+# to terminfo with tic -I.  Some very old obsolete BSD caps like :kn: are
+# in this class.  Nothing will ever use them again.
+#
+# More usually, you want the compiler to try to deduce something from the
+# capability value that it can use to translate it into your output format.
+# You'll need to write custom code, probably in postprocess_termcap() or
+# postprocess_terminfo(), to handle the translation.
+#
+# CONTROLLING ENTRY LENGTH
+#
+# Notes on specific elisions made to fit translations within 1023 bytes:
+#
+# Machines with IBM PC-like keyboards want to be able to define the following
+# keys: key_npage, key_ppage, key_home, key_ll (which is used for in termcap-
+# only environments for End or Home-Down), key_dc, and key_ic.  This is also
+# the set of keys the `joe' editor will be upset if it can't see.  So don't
+# trim those out of the set to be translated to termcap, or various users of
+# the termcap file will become irate.
+#
+# It might look tempting to leave those long init strings out of translations.
+# We can't do it (yet); 4.4BSD tput and tset use them.
+#
+# We retain the sgr capability in translation in spite of the fact that neither
+# 4.4BSD nor GNU Emacs uses it, because (a) some entry naming distinctions are
+# hard to understand without it, and (b) the entries in which it is long tend
+# to be older types that don't use up a lot of string space on function keys.
+# The tic(1) translation code will complain and elide it if it makes a critical
+# difference (there is special code in tic to recognize this situation).
+#
+# Yes, BSD tset(1) uses hpa.  We elide hpa/vpa anyway because the motion
+# optimizer in BSD curses didn't use them.  This omission seems to be the
+# single most effective one, it shortened the resolved length of all thirteen
+# problem entries in the 9.9.0 version of the terminfo master below critical.
+#
+# It would be nice to keep f11 and f12 for Emacs use, but a couple of termcap
+# translations go back over critical if we do this.  As 4.4BSD curses fades
+# into history and GNU termcap's application base shrinks towards being GNU
+# Emacs only, we'll probably elide out some BSD-only capabilities in order
+# to buy space for non-essentials Emacs is still using.  Capabilities high
+# on that hit list: rc, sc, uc.

+#
+# STANDARD CAPABILITIES
+#
+#%The following is a complete table of the capabilities included in a
+#%terminfo description block and available to terminfo-using code.  In each
+#%line of the table,
+#%
+#%The \fBvariable\fR is the name by which the programmer (at the terminfo level)
+#%accesses the capability.
+#%
+#%The \fBcapname\fR is the short name used in the text of the database,
+#%and is used by a person updating the database.
+#%Whenever possible, capnames are chosen to be the same as or similar to
+#%the ANSI X3.64-1979 standard (now superseded by ECMA-48, which uses
+#%identical or very similar names).  Semantics are also intended to match
+#%those of the specification.
+#%
+#%The termcap code is the old
+#%.B termcap
+#%capability name (some capabilities are new, and have names which termcap
+#%did not originate).
+#%.P
+#%Capability names have no hard length limit, but an informal limit of 5
+#%characters has been adopted to keep them short and to allow the tabs in
+#%the source file
+#%.B Caps
+#%to line up nicely.
+#%
+#%Finally, the description field attempts to convey the semantics of the
+#%capability.  You may find some codes in the description field:
+#%.TP
+#%(P)
+#%indicates that padding may be specified
+#%.TP
+#%#[1-9]
+#%in the description field indicates that the string is passed
+#%through \fBtparm\fP(3X) with parameters as given (#\fIi\fP).
+#%.IP
+#%If no parameters are listed in the description,
+#%passing the string through \fBtparm\fP(3X) may give unexpected results,
+#%e.g., if it contains percent (%%) signs.
+#%.TP
+#%(P*)
+#%indicates that padding may vary in proportion to the number of
+#%lines affected
+#%.TP
+#%(#\d\fIi\fP\u)
+#%indicates the \fIi\fP\uth\d parameter.
+#%
+#%.PP

+# TERMCAP EXTENSION CAPABILITIES
+#
+# The capabilities below are either obsolete or extensions on certain systems.
+# They are not used by SVR4 terminfo.  Some are used by captoinfo to translate
+# termcap sources; the rest are listed for completeness, and in case somebody
+# cares about them enough to hack in code that will translate them into
+# terminfo capabilities.
+#
+# The first part of the list is from Ross Ridge's `mytinfo' package
+# (comp.sources.unix, volume 26); the variable names and terminfo names (as
+# well as the termcap codes) match his list.
+#
+# This group of codes is not marked obsolete in 4.4BSD, but have no direct
+# terminfo equivalents.  The rs capability is specially translated to terminfo
+# r2, and vice versa, if an entry does not already have an r2.  Similarly,
+# i2 is translated to r3 if there is no r3 (because SV terminfo maps is to i2).
+# The ug capability is thrown away, but assumed to be whatever sg is if the
+# latter is nonzero and we're dumping in termcap format.
+#

+termcap_reset			OTrs	str	rs	-		-	YB-G-	terminal reset string
+magic_cookie_glitch_ul		OTug	num	ug	-		-	YBCGE	number of blanks left by ul
+#
+# Obsolete termcap capabilities.  Some are used for termcap translation.  The

+# printing them in terminfo source dumps of compiled entries.

+#
+# The following comments describe capnames so ancient that I believe no

+# clash with terminfo names in ways that cannot be resolved by type
+# information.
+#
+# These mytinfo codes are not used in the 4.4BSD curses code.  They are
+# marked obsolete in the 4.4BSD manual pages.
+#
+# There is one conflict with terminfo; ma is in both.  This conflict is
+# resolved by type information.
+#
+# The `ko' capability is translated by special code.  It should contain a
+# comma-separated list of capabilities for which there are corresponding keys.
+# The `kn' code is accepted but ignored.
+#
+# The `ma' capability was a 4.0BSD feature used by vi version 2.
+# It consists of pairs of characters corresponding to kl, kr, ku, kd, and kh.
+# Besides being obsolete, that interpretation conflicts with max_attributes.
+#
+# Here is a description of memory_lock_above and memory_unlock:
+# "You can 'freeze' data on the screen by turning on Memory Lock in a line of
+# text.  All lines above the cursor's current line become locked in place on

+# under the frozen data.  Lines scrolled off the screen are inserted into
+# memory immediately preceding the first frozen line." (from the HP 700/96
+# User's manual).  VT100/ANSI memory lock set is \E[>2h, reset is \E[>2l.

+#
+# This is an adaptation of ncurses' termcap/terminfo capability table, which
+# is illustrates an experimental extension to describe alt-, shift- and
+# control-modifiers applied to function and normal keys, as done on IBM pc's.
+#
+# This table is used to generate initializers for tables that drive tic,
+# infocmp, and the library compilation code used to support the termcap
+# compatibility hack.  It is also used to generate the tabular portion of the
+# terminfo(5) man page; lines beginning with `#%' are passed through to become
+# the terminfo table.
+#
+# This file has three major sections; a standard-capabilities table, two
+# extension-capability tables, and a section of aliases declarations.
+# The first two have the same format, as follows:
+#
+# FILE FORMAT
+#
+# Column 1: terminfo variable name
+# Column 2: terminfo capability name
+# Column 3: capability type (boolean, numeric, or string)
+# Column 4: termcap capability name
+# Column 5: KEY_xxx name, if any, `-' otherwise
+# Column 6: value for KEY_xxx name, if any, `-' otherwise
+# Column 7: Lead with `Y' if capability should be emitted in termcap
+#           translations, `-' otherwise
+# Column 8: capability description
+#
+# The codes following [Y-] in column 7 describe the versions of termcap which
+# use the given capability.  This information is not used by the curses library
+# proper; rather, it is there to help the terminfo maintainer avoid emitting
+# termcap entry translations that are more than 1023 bytes long (and tank a
+# lot of old termcap-using programs).  The codes read as follows:
+#	B = mentioned in the BSD man page for 4.4BSD curses
+#	C = used by the 4.4BSD curses library
+#	G = mentioned in the documentation for GNU termcap
+#	E = used by GNU Emacs
+#	K = remove this terminfo capability when translating to standard format
+# The important codes are C and E.  A cap with C or E should be preserved in
+# translation if possible.  The problem is that preserving all such caps may
+# lead to some termcap translations being too long.  The termcap maintainer
+# has a bit of a juggling act to do...potential problem cases are marked with
+# an asterisk (*).
+#
+# The aliases section has the following format:
+#
+# Column 1: either `capalias' or `infoalias'
+# Column 2: name to be aliased
+# Column 3: what name it should translate to.  The name IGNORE means it
+#           should be discarded with a warning message.
+# Column 4: name of the extension set (used for compiler warning messages)
+# Column 5: capability description (usually an associated terminfo variable)
+#
+# HANDLING TERMCAP AND TERMINFO EXTENSIONS
+#
+# There are basically five different ways to handle termcap and terminfo
+# extensions:
+#
+# 1. Don't list the capname here, or list it but comment it out (the latter
+# is preferable; someone might want to handle it in the future).  If you do
+# this, the capability will be treated as unknown and raise a warning from
+# the compiler.
+#
+# 2. Alias it.  This is appropriate if the capability has the same meaning
+# as an already-supported one.  The compiler will handle aliasing, emitting
+# an appropriate informational message whenever an alias fires.
+#
+# 3. List it in the standard table.  You almost certainly do *not* want
+# to do this -- the capabilities in that one, and their order, have been
+# carefully chosen to be SVr4-binary-compatible when they're written out
+# as a terminfo object, and breaking this would be bad.  It is up to the ncurses
+# library what to do with the terminfo data after it is read in.
+#
+# 4. List it in the aliases table with an IGNORE target field.  If you
+# do this, the capability will be ignored on input (though the user will
+# get a warning message about it).
+#
+# 5. List it in the extensions table. If you do this, the compiler will
+# silently accept the capability, but the curses library proper will never
+# see it (because it won't be written out as part of the terminfo object
+# format).  It is up to you what you have the compiler do with it.
+#
+# There are two opposite reasons to choose option 5.  One is when you want
+# to eat the capability silently and discard it when doing translations
+# to terminfo with tic -I.  Some very old obsolete BSD caps like :kn: are
+# in this class.  Nothing will ever use them again.
+#
+# More usually, you want the compiler to try to deduce something from the
+# capability value that it can use to translate it into your output format.
+# You'll need to write custom code, probably in postprocess_termcap() or
+# postprocess_terminfo(), to handle the translation.
+#
+# CONTROLLING ENTRY LENGTH
+#
+# Notes on specific elisions made to fit translations within 1023 bytes:
+#
+# Machines with IBM PC-like keyboards want to be able to define the following
+# keys: key_npage, key_ppage, key_home, key_ll (which is used for in termcap-
+# only environments for End or Home-Down), key_dc, and key_ic.  This is also
+# the set of keys the `joe' editor will be upset if it can't see.  So don't
+# trim those out of the set to be translated to termcap, or various users of
+# the termcap file will become irate.
+#
+# It might look tempting to leave those long init strings out of translations.
+# We can't do it (yet); 4.4BSD tput and tset use them.
+#
+# We retain the sgr capability in translation in spite of the fact that neither
+# 4.4BSD nor GNU Emacs uses it, because (a) some entry naming distinctions are
+# hard to understand without it, and (b) the entries in which it is long tend
+# to be older types that don't use up a lot of string space on function keys.
+# The tic(1) translation code will complain and elide it if it makes a critical
+# difference (there is special code in tic to recognize this situation).
+#
+# Yes, BSD tset(1) uses hpa.  We elide hpa/vpa anyway because the motion
+# optimizer in BSD curses didn't use them.  This omission seems to be the
+# single most effective one, it shortened the resolved length of all thirteen
+# problem entries in the 9.9.0 version of the terminfo master below critical.
+#
+# It would be nice to keep f11 and f12 for Emacs use, but a couple of termcap
+# translations go back over critical if we do this.  As 4.4BSD curses fades
+# into history and GNU termcap's application base shrinks towards being GNU
+# Emacs only, we'll probably elide out some BSD-only capabilities in order
+# to buy space for non-essentials Emacs is still using.  Capabilities high
+# on that hit list: rc, sc, uc.

+# STANDARD CAPABILITIES
+#
+#%The following is a complete table of the capabilities included in a
+#%terminfo description block and available to terminfo-using code.  In each
+#%line of the table,
+#%
+#%The \fBvariable\fR is the name by which the programmer (at the terminfo level)
+#%accesses the capability.
+#%
+#%The \fBcapname\fR is the short name used in the text of the database,
+#%and is used by a person updating the database.
+#%Whenever possible, capnames are chosen to be the same as or similar to
+#%the ANSI X3.64-1979 standard (now superseded by ECMA-48, which uses
+#%identical or very similar names).  Semantics are also intended to match
+#%those of the specification.
+#%
+#%The termcap code is the old
+#%.B termcap
+#%capability name (some capabilities are new, and have names which termcap
+#%did not originate).
+#%.P
+#%Capability names have no hard length limit, but an informal limit of 5
+#%characters has been adopted to keep them short and to allow the tabs in
+#%the source file
+#%.B Caps
+#%to line up nicely.
+#%
+#%Finally, the description field attempts to convey the semantics of the
+#%capability.  You may find some codes in the description field:
+#%.TP
+#%(P)
+#%indicates that padding may be specified
+#%.TP
+#%#[1-9]
+#%in the description field indicates that the string is passed
+#%through \fBtparm\fP(3X) with parameters as given (#\fIi\fP).
+#%.IP
+#%If no parameters are listed in the description,
+#%passing the string through \fBtparm\fP(3X) may give unexpected results,
+#%e.g., if it contains percent (%%) signs.
+#%.TP
+#%(P*)
+#%indicates that padding may vary in proportion to the number of
+#%lines affected
+#%.TP
+#%(#\d\fIi\fP\u)
+#%indicates the \fIi\fP\uth\d parameter.

+# TERMCAP EXTENSION CAPABILITIES
+#
+# The capabilities below are either obsolete or extensions on certain systems.
+# They are not used by SVR4 terminfo.  Some are used by captoinfo to translate
+# termcap sources; the rest are listed for completeness, and in case somebody
+# cares about them enough to hack in code that will translate them into
+# terminfo capabilities.
+#
+# The first part of the list is from Ross Ridge's `mytinfo' package
+# (comp.sources.unix, volume 26); the variable names and terminfo names (as
+# well as the termcap codes) match his list.
+#
+# This group of codes is not marked obsolete in 4.4BSD, but have no direct
+# terminfo equivalents.  The rs capability is specially translated to terminfo
+# r2, and vice versa, if an entry does not already have an r2.  Similarly,
+# i2 is translated to r3 if there is no r3 (because SV terminfo maps is to i2).
+# The ug capability is thrown away, but assumed to be whatever sg is if the
+# latter is nonzero and we're dumping in termcap format.

+#
+# This is an adaptation of ncurses' termcap/terminfo capability table, which
+# is designed to align with OSF/1 version 5 (Tru64) terminfo.
+#
+# This table is used to generate initializers for tables that drive tic,
+# infocmp, and the library compilation code used to support the termcap
+# compatibility hack.  It is also used to generate the tabular portion of the
+# terminfo(5) man page; lines beginning with `#%' are passed through to become
+# the terminfo table.
+#
+# This file has three major sections; a standard-capabilities table, two
+# extension-capability tables, and a section of aliases declarations.
+# The first two have the same format, as follows:
+#
+# FILE FORMAT
+#
+# Column 1: terminfo variable name
+# Column 2: terminfo capability name
+# Column 3: capability type (boolean, numeric, or string)
+# Column 4: termcap capability name
+# Column 5: KEY_xxx name, if any, `-' otherwise
+# Column 6: value for KEY_xxx name, if any, `-' otherwise
+# Column 7: Lead with `Y' if capability should be emitted in termcap
+#           translations, `-' otherwise
+# Column 8: capability description
+#
+# The codes following [Y-] in column 7 describe the versions of termcap which
+# use the given capability.  This information is not used by the curses library
+# proper; rather, it is there to help the terminfo maintainer avoid emitting
+# termcap entry translations that are more than 1023 bytes long (and tank a
+# lot of old termcap-using programs).  The codes read as follows:
+#	B = mentioned in the BSD man page for 4.4BSD curses
+#	C = used by the 4.4BSD curses library
+#	G = mentioned in the documentation for GNU termcap
+#	E = used by GNU Emacs
+#	K = remove this terminfo capability when translating to standard format
+# The important codes are C and E.  A cap with C or E should be preserved in
+# translation if possible.  The problem is that preserving all such caps may
+# lead to some termcap translations being too long.  The termcap maintainer
+# has a bit of a juggling act to do...potential problem cases are marked with
+# an asterisk (*).
+#
+# The aliases section has the following format:
+#
+# Column 1: either `capalias' or `infoalias'
+# Column 2: name to be aliased
+# Column 3: what name it should translate to.  The name IGNORE means it
+#           should be discarded with a warning message.
+# Column 4: name of the extension set (used for compiler warning messages)
+# Column 5: capability description (usually an associated terminfo variable)
+#
+# HANDLING TERMCAP AND TERMINFO EXTENSIONS
+#
+# There are basically five different ways to handle termcap and terminfo
+# extensions:
+#
+# 1. Don't list the capname here, or list it but comment it out (the latter
+# is preferable; someone might want to handle it in the future).  If you do
+# this, the capability will be treated as unknown and raise a warning from
+# the compiler.
+#
+# 2. Alias it.  This is appropriate if the capability has the same meaning
+# as an already-supported one.  The compiler will handle aliasing, emitting
+# an appropriate informational message whenever an alias fires.
+#
+# 3. List it in the standard table.  You almost certainly do *not* want
+# to do this -- the capabilities in that one, and their order, have been
+# carefully chosen to be SVr4-binary-compatible when they're written out
+# as a terminfo object, and breaking this would be bad.  It is up to the ncurses
+# library what to do with the terminfo data after it is read in.
+#
+# 4. List it in the aliases table with an IGNORE target field.  If you
+# do this, the capability will be ignored on input (though the user will
+# get a warning message about it).
+#
+# 5. List it in the extensions table. If you do this, the compiler will
+# silently accept the capability, but the curses library proper will never
+# see it (because it won't be written out as part of the terminfo object
+# format).  It is up to you what you have the compiler do with it.
+#
+# There are two opposite reasons to choose option 5.  One is when you want
+# to eat the capability silently and discard it when doing translations
+# to terminfo with tic -I.  Some very old obsolete BSD caps like :kn: are
+# in this class.  Nothing will ever use them again.
+#
+# More usually, you want the compiler to try to deduce something from the
+# capability value that it can use to translate it into your output format.
+# You'll need to write custom code, probably in postprocess_termcap() or
+# postprocess_terminfo(), to handle the translation.
+#
+# CONTROLLING ENTRY LENGTH
+#
+# Notes on specific elisions made to fit translations within 1023 bytes:
+#
+# Machines with IBM PC-like keyboards want to be able to define the following
+# keys: key_npage, key_ppage, key_home, key_ll (which is used for in termcap-
+# only environments for End or Home-Down), key_dc, and key_ic.  This is also
+# the set of keys the `joe' editor will be upset if it can't see.  So don't
+# trim those out of the set to be translated to termcap, or various users of
+# the termcap file will become irate.
+#
+# It might look tempting to leave those long init strings out of translations.
+# We can't do it (yet); 4.4BSD tput and tset use them.
+#
+# We retain the sgr capability in translation in spite of the fact that neither
+# 4.4BSD nor GNU Emacs uses it, because (a) some entry naming distinctions are
+# hard to understand without it, and (b) the entries in which it is long tend
+# to be older types that don't use up a lot of string space on function keys.
+# The tic(1) translation code will complain and elide it if it makes a critical
+# difference (there is special code in tic to recognize this situation).
+#
+# Yes, BSD tset(1) uses hpa.  We elide hpa/vpa anyway because the motion
+# optimizer in BSD curses didn't use them.  This omission seems to be the
+# single most effective one, it shortened the resolved length of all thirteen
+# problem entries in the 9.9.0 version of the terminfo master below critical.
+#
+# It would be nice to keep f11 and f12 for Emacs use, but a couple of termcap
+# translations go back over critical if we do this.  As 4.4BSD curses fades
+# into history and GNU termcap's application base shrinks towards being GNU
+# Emacs only, we'll probably elide out some BSD-only capabilities in order
+# to buy space for non-essentials Emacs is still using.  Capabilities high
+# on that hit list: rc, sc, uc.

+# STANDARD CAPABILITIES
+#
+#%The following is a complete table of the capabilities included in a
+#%terminfo description block and available to terminfo-using code.  In each
+#%line of the table,
+#%
+#%The \fBvariable\fR is the name by which the programmer (at the terminfo level)
+#%accesses the capability.
+#%
+#%The \fBcapname\fR is the short name used in the text of the database,
+#%and is used by a person updating the database.
+#%Whenever possible, capnames are chosen to be the same as or similar to
+#%the ANSI X3.64-1979 standard (now superseded by ECMA-48, which uses
+#%identical or very similar names).  Semantics are also intended to match
+#%those of the specification.
+#%
+#%The termcap code is the old
+#%.B termcap
+#%capability name (some capabilities are new, and have names which termcap
+#%did not originate).
+#%.P
+#%Capability names have no hard length limit, but an informal limit of 5
+#%characters has been adopted to keep them short and to allow the tabs in
+#%the source file
+#%.B Caps
+#%to line up nicely.
+#%
+#%Finally, the description field attempts to convey the semantics of the
+#%capability.  You may find some codes in the description field:
+#%.TP
+#%(P)
+#%indicates that padding may be specified
+#%.TP
+#%#[1-9]
+#%in the description field indicates that the string is passed
+#%through \fBtparm\fP(3X) with parameters as given (#\fIi\fP).
+#%.IP
+#%If no parameters are listed in the description,
+#%passing the string through \fBtparm\fP(3X) may give unexpected results,
+#%e.g., if it contains percent (%%) signs.
+#%.TP
+#%(P*)
+#%indicates that padding may vary in proportion to the number of
+#%lines affected
+#%.TP
+#%(#\d\fIi\fP\u)
+#%indicates the \fIi\fP\uth\d parameter.

+# TERMCAP EXTENSION CAPABILITIES
+#
+# The capabilities below are either obsolete or extensions on certain systems.
+# They are not used by SVR4 terminfo.  Some are used by captoinfo to translate
+# termcap sources; the rest are listed for completeness, and in case somebody
+# cares about them enough to hack in code that will translate them into
+# terminfo capabilities.
+#
+# The first part of the list is from Ross Ridge's `mytinfo' package
+# (comp.sources.unix, volume 26); the variable names and terminfo names (as
+# well as the termcap codes) match his list.
+#
+# This group of codes is not marked obsolete in 4.4BSD, but have no direct
+# terminfo equivalents.  The rs capability is specially translated to terminfo
+# r2, and vice versa, if an entry does not already have an r2.  Similarly,
+# i2 is translated to r3 if there is no r3 (because SV terminfo maps is to i2).
+# The ug capability is thrown away, but assumed to be whatever sg is if the
+# latter is nonzero and we're dumping in termcap format.

+# Obsolete termcap capabilities.  Some are used for termcap translation.  The

+#
+# This is an adaptation of ncurses' termcap/terminfo capability table, which
+# is designed to align with U/Win's terminfo.
+#
+# This table is used to generate initializers for tables that drive tic,
+# infocmp, and the library compilation code used to support the termcap
+# compatibility hack.  It is also used to generate the tabular portion of the
+# terminfo(5) man page; lines beginning with `#%' are passed through to become
+# the terminfo table.
+#
+# This file has three major sections; a standard-capabilities table, two
+# extension-capability tables, and a section of aliases declarations.
+# The first two have the same format, as follows:
+#
+# FILE FORMAT
+#
+# Column 1: terminfo variable name
+# Column 2: terminfo capability name
+# Column 3: capability type (boolean, numeric, or string)
+# Column 4: termcap capability name
+# Column 5: KEY_xxx name, if any, `-' otherwise
+# Column 6: value for KEY_xxx name, if any, `-' otherwise
+# Column 7: Lead with `Y' if capability should be emitted in termcap
+#           translations, `-' otherwise
+# Column 8: capability description
+#
+# The codes following [Y-] in column 7 describe the versions of termcap which
+# use the given capability.  This information is not used by the curses library
+# proper; rather, it is there to help the terminfo maintainer avoid emitting
+# termcap entry translations that are more than 1023 bytes long (and tank a
+# lot of old termcap-using programs).  The codes read as follows:
+#	B = mentioned in the BSD man page for 4.4BSD curses
+#	C = used by the 4.4BSD curses library
+#	G = mentioned in the documentation for GNU termcap
+#	E = used by GNU Emacs
+#	K = remove this terminfo capability when translating to standard format
+# The important codes are C and E.  A cap with C or E should be preserved in
+# translation if possible.  The problem is that preserving all such caps may
+# lead to some termcap translations being too long.  The termcap maintainer
+# has a bit of a juggling act to do...potential problem cases are marked with
+# an asterisk (*).
+#
+# The aliases section has the following format:
+#
+# Column 1: either `capalias' or `infoalias'
+# Column 2: name to be aliased
+# Column 3: what name it should translate to.  The name IGNORE means it
+#           should be discarded with a warning message.
+# Column 4: name of the extension set (used for compiler warning messages)
+# Column 5: capability description (usually an associated terminfo variable)
+#
+# HANDLING TERMCAP AND TERMINFO EXTENSIONS
+#
+# There are basically five different ways to handle termcap and terminfo
+# extensions:
+#
+# 1. Don't list the capname here, or list it but comment it out (the latter
+# is preferable; someone might want to handle it in the future).  If you do
+# this, the capability will be treated as unknown and raise a warning from
+# the compiler.
+#
+# 2. Alias it.  This is appropriate if the capability has the same meaning
+# as an already-supported one.  The compiler will handle aliasing, emitting
+# an appropriate informational message whenever an alias fires.
+#
+# 3. List it in the standard table.  You almost certainly do *not* want
+# to do this -- the capabilities in that one, and their order, have been
+# carefully chosen to be SVr4-binary-compatible when they're written out
+# as a terminfo object, and breaking this would be bad.  It is up to the ncurses
+# library what to do with the terminfo data after it is read in.
+#
+# 4. List it in the aliases table with an IGNORE target field.  If you
+# do this, the capability will be ignored on input (though the user will
+# get a warning message about it).
+#
+# 5. List it in the extensions table. If you do this, the compiler will
+# silently accept the capability, but the curses library proper will never
+# see it (because it won't be written out as part of the terminfo object
+# format).  It is up to you what you have the compiler do with it.
+#
+# There are two opposite reasons to choose option 5.  One is when you want
+# to eat the capability silently and discard it when doing translations
+# to terminfo with tic -I.  Some very old obsolete BSD caps like :kn: are
+# in this class.  Nothing will ever use them again.
+#
+# More usually, you want the compiler to try to deduce something from the
+# capability value that it can use to translate it into your output format.
+# You'll need to write custom code, probably in postprocess_termcap() or
+# postprocess_terminfo(), to handle the translation.
+#
+# CONTROLLING ENTRY LENGTH
+#
+# Notes on specific elisions made to fit translations within 1023 bytes:
+#
+# Machines with IBM PC-like keyboards want to be able to define the following
+# keys: key_npage, key_ppage, key_home, key_ll (which is used for in termcap-
+# only environments for End or Home-Down), key_dc, and key_ic.  This is also
+# the set of keys the `joe' editor will be upset if it can't see.  So don't
+# trim those out of the set to be translated to termcap, or various users of
+# the termcap file will become irate.
+#
+# It might look tempting to leave those long init strings out of translations.
+# We can't do it (yet); 4.4BSD tput and tset use them.
+#
+# We retain the sgr capability in translation in spite of the fact that neither
+# 4.4BSD nor GNU Emacs uses it, because (a) some entry naming distinctions are
+# hard to understand without it, and (b) the entries in which it is long tend
+# to be older types that don't use up a lot of string space on function keys.
+# The tic(1) translation code will complain and elide it if it makes a critical
+# difference (there is special code in tic to recognize this situation).
+#
+# Yes, BSD tset(1) uses hpa.  We elide hpa/vpa anyway because the motion
+# optimizer in BSD curses didn't use them.  This omission seems to be the
+# single most effective one, it shortened the resolved length of all thirteen
+# problem entries in the 9.9.0 version of the terminfo master below critical.
+#
+# It would be nice to keep f11 and f12 for Emacs use, but a couple of termcap
+# translations go back over critical if we do this.  As 4.4BSD curses fades
+# into history and GNU termcap's application base shrinks towards being GNU
+# Emacs only, we'll probably elide out some BSD-only capabilities in order
+# to buy space for non-essentials Emacs is still using.  Capabilities high
+# on that hit list: rc, sc, uc.

+#
+# STANDARD CAPABILITIES
+#
+#%The following is a complete table of the capabilities included in a
+#%terminfo description block and available to terminfo-using code.  In each
+#%line of the table,
+#%
+#%The \fBvariable\fR is the name by which the programmer (at the terminfo level)
+#%accesses the capability.
+#%
+#%The \fBcapname\fR is the short name used in the text of the database,
+#%and is used by a person updating the database.
+#%Whenever possible, capnames are chosen to be the same as or similar to
+#%the ANSI X3.64-1979 standard (now superseded by ECMA-48, which uses
+#%identical or very similar names).  Semantics are also intended to match
+#%those of the specification.
+#%
+#%The termcap code is the old
+#%.B termcap
+#%capability name (some capabilities are new, and have names which termcap
+#%did not originate).
+#%.P
+#%Capability names have no hard length limit, but an informal limit of 5
+#%characters has been adopted to keep them short and to allow the tabs in
+#%the source file
+#%.B Caps
+#%to line up nicely.
+#%
+#%Finally, the description field attempts to convey the semantics of the
+#%capability.  You may find some codes in the description field:
+#%.TP
+#%(P)
+#%indicates that padding may be specified
+#%.TP
+#%#[1-9]
+#%in the description field indicates that the string is passed
+#%through \fBtparm\fP(3X) with parameters as given (#\fIi\fP).
+#%.IP
+#%If no parameters are listed in the description,
+#%passing the string through \fBtparm\fP(3X) may give unexpected results,
+#%e.g., if it contains percent (%%) signs.
+#%.TP
+#%(P*)
+#%indicates that padding may vary in proportion to the number of
+#%lines affected
+#%.TP
+#%(#\d\fIi\fP\u)
+#%indicates the \fIi\fP\uth\d parameter.

+# TERMCAP EXTENSION CAPABILITIES
+#
+# The capabilities below are either obsolete or extensions on certain systems.
+# They are not used by SVR4 terminfo.  Some are used by captoinfo to translate
+# termcap sources; the rest are listed for completeness, and in case somebody
+# cares about them enough to hack in code that will translate them into
+# terminfo capabilities.
+#
+# The first part of the list is from Ross Ridge's `mytinfo' package
+# (comp.sources.unix, volume 26); the variable names and terminfo names (as
+# well as the termcap codes) match his list.
+#
+# This group of codes is not marked obsolete in 4.4BSD, but have no direct
+# terminfo equivalents.  The rs capability is specially translated to terminfo
+# r2, and vice versa, if an entry does not already have an r2.  Similarly,
+# i2 is translated to r3 if there is no r3 (because SV terminfo maps is to i2).
+# The ug capability is thrown away, but assumed to be whatever sg is if the
+# latter is nonzero and we're dumping in termcap format.
+#

+termcap_reset			OTrs	str	rs	-		-	YB-G-	terminal reset string
+magic_cookie_glitch_ul		OTug	num	ug	-		-	YBCGE	number of blanks left by ul
+#
+# Obsolete termcap capabilities.  Some are used for termcap translation.  The

+# printing them in terminfo source dumps of compiled entries.

+#
+# The following comments describe capnames so ancient that I believe no

+# clash with terminfo names in ways that cannot be resolved by type
+# information.
+#
+# These mytinfo codes are not used in the 4.4BSD curses code.  They are
+# marked obsolete in the 4.4BSD manual pages.
+#
+# There is one conflict with terminfo; ma is in both.  This conflict is
+# resolved by type information.
+#
+# The `ko' capability is translated by special code.  It should contain a
+# comma-separated list of capabilities for which there are corresponding keys.
+# The `kn' code is accepted but ignored.
+#
+# The `ma' capability was a 4.0BSD feature used by vi version 2.
+# It consists of pairs of characters corresponding to kl, kr, ku, kd, and kh.
+# Besides being obsolete, that interpretation conflicts with max_attributes.
+#
+# Here is a description of memory_lock_above and memory_unlock:
+# "You can 'freeze' data on the screen by turning on Memory Lock in a line of

+# further data entered forces the first line of unfrozen line text to scroll
+# under the frozen data.  Lines scrolled off the screen are inserted into
+# memory immediately preceding the first frozen line." (from the HP 700/96
+# User's manual).  VT100/ANSI memory lock set is \E[>2h, reset is \E[>2l.

+.SH NAME
+adacurses@USE_CFG_SUFFIX@\-config \- helper script for @ADA_LIBNAME@ libraries
+.SH SYNOPSIS
+.B \*C
+[\fIoptions\fP]
+.SH DESCRIPTION
+This is a shell script which simplifies configuring an application to use
+the @ADA_LIBNAME@ library binding to ncurses.
+.SH OPTIONS
+.TP
+\fB\-\-cflags\fP
+echos the gnat (Ada compiler) flags needed to compile with @ADA_LIBNAME@.
+.TP
+\fB\-\-libs\fP
+echos the gnat libraries needed to link with @ADA_LIBNAME@.
+.TP
+\fB\-\-version\fP
+echos the release+patchdate version of the ncurses libraries used
+to configure and build @ADA_LIBNAME@.
+.TP
+\fB\-\-help\fP
+prints a list of the \fB\*C\fP script's options.
+.PP
+If no options are given, \fB\*C\fP prints the combination
+of
+\fB\-\-cflags\fP and
+\fB\-\-libs\fP
+that \fBgnatmake\fP expects (see example).
+.SH EXAMPLE
+.PP
+For example, supposing that you want to compile the "Hello World!"
+program for @ADA_LIBNAME@.
+Make a file named "hello.adb":
+.RS
+.nf
+.ft CW
+with Terminal_Interface.Curses; use Terminal_Interface.Curses;
+
+procedure Hello is
+
+   Visibility : Cursor_Visibility := Invisible;
+   done : Boolean := False;
+   c : Key_Code;
+
+begin
+
+   Init_Screen;
+   Set_Echo_Mode (False);
+
+   Set_Cursor_Visibility (Visibility);
+   Set_Timeout_Mode (Standard_Window, Non_Blocking, 0);
+
+   Move_Cursor (Line => Lines / 2, Column => (Columns - 12) / 2);
+   Add (Str => "Hello World!");
+
+   while not done loop
+
+      c := Get_Keystroke (Standard_Window);
+      case c is
+      when Character'Pos ('q') => done := True;
+      when others => null;
+      end case;
+
+      Nap_Milli_Seconds (50);
+   end loop;
+
+   End_Windows;
+
+end Hello;
+.fi
+.RE
+.PP
+Then, using
+.RS
+.ft CW
+gnatmake `adacurses-config --cflags` hello -largs `adacurses-config --libs`
+.ft
+.RE
+.PP
+or (simpler):
+.RS
+.ft CW
+gnatmake hello `adacurses-config`
+.ft
+.RE
+.PP
+you will compile and link the program.
+.SH "SEE ALSO"

+.SH SYNOPSIS
+\fB@CAPTOINFO@\fR [\fB\-v\fIn\fR \fIwidth\fR]  [\fB\-V\fR] [\fB\-1\fR] [\fB\-w\fR \fIwidth\fR] \fIfile\fR ...
+.SH DESCRIPTION
+\fB@CAPTOINFO@\fP looks in each given text
+\fIfile\fP for \fBtermcap\fP descriptions.
+For each
+one found, an equivalent \fBterminfo\fP description is written to standard
+output.
+Termcap \fBtc\fP capabilities are translated directly to terminfo
+\fBuse\fP capabilities.
+.PP
+If no \fIfile\fP is given, then the environment variable \fBTERMCAP\fP is used
+for the filename or entry.
+If \fBTERMCAP\fP is a full pathname to a file, only
+the terminal whose name is specified in the environment variable \fBTERM\fP is
+extracted from that file.
+If the environment variable \fBTERMCAP\fP is not
+set, then the file \fB\*d\fP is read.
+.TP 5
+\fB\-v\fP
+print out tracing information on standard error as the program runs.
+.TP 5
+\fB\-V\fP
+print out the version of the program in use on standard error and exit.
+.TP 5
+\fB\-1\fP
+cause the fields to print out one to a line.
+Otherwise, the fields
+will be printed several to a line to a maximum width of 60
+characters.
+.TP 5
+\fB\-w\fP
+change the output to \fIwidth\fP characters.
+.SH FILES
+.TP 20
+\*d
+Compiled terminal description database.
+.SH TRANSLATIONS FROM NONSTANDARD CAPABILITIES
+.PP
+Some obsolete nonstandard capabilities will automatically be translated
+into standard (SVr4/XSI Curses) terminfo capabilities by \fB@CAPTOINFO@\fP.
+Whenever one of these automatic translations is done, the program
+will issue an notification to stderr, inviting the user to check that
+it has not mistakenly translated a completely unknown and random
+capability and/or syntax error.

+.SH NAME
+\fB@CLEAR@\fP \- clear the terminal screen
+.SH SYNOPSIS
+\fB@CLEAR@\fR [\fB\-T\fItype\fR] [\fB\-V\fR] [\fB\-x\fR]
+.br
+.SH DESCRIPTION
+\fB@CLEAR@\fP clears your terminal's screen if this is possible,
+including the terminal's scrollback buffer
+(if the extended \*(``E3\*('' capability is defined).
+\fB@CLEAR@\fP looks in the environment for the terminal type
+given by the environment variable \fBTERM\fP,
+and then in the
+\fBterminfo\fP database to determine how to clear the screen.
+.PP
+\fB@CLEAR@\fP writes to the standard output.
+You can redirect the standard output to a file (which prevents
+\fB@CLEAR@\fP from actually clearing the screen),
+and later \fBcat\fP the file to the screen, clearing it at that point.
+.SH OPTIONS
+.PP
+.TP 5
+.B \-T \fItype\fP
+indicates the \fItype\fP of terminal.
+Normally this option is
+unnecessary, because the default is taken from the environment
+variable \fBTERM\fP.
+If \fB\-T\fP is specified, then the shell
+variables \fBLINES\fP and \fBCOLUMNS\fP will also be ignored.
+.TP
+.B \-V
+reports the version of ncurses which was used in this program, and exits.
+The options are as follows:
+.TP
+.B \-x
+do not attempt to clear the terminal's scrollback buffer
+using the extended \*(``E3\*('' capability.
+.SH HISTORY
+A \fBclear\fP command appeared in 2.79BSD dated February 24, 1979.
+Later that was provided in Unix 8th edition (1985).
+.PP
+AT&T adapted a different BSD program (\fBtset\fP) to make
+a new command (\fBtput\fP),
+and used this to replace the \fBclear\fP command with a shell script
+which calls \fBtput clear\fP, e.g.,
+.NS
+/usr/bin/tput ${1:+-T$1} clear 2> /dev/null
+exit
+.NE
+.PP
+In 1989, when Keith Bostic revised the BSD \fBtput\fP command
+to make it similar to the AT&T \fBtput\fP,
+he added a shell script for the \fBclear\fP command:
+.NS
+exec tput clear
+.NE
+.PP
+The remainder of the script in each case is a copyright notice.
+.PP
+The ncurses \fBclear\fP command began in 1995 by adapting the original
+BSD \fBclear\fP command (with terminfo, of course).
+.PP
+The \fBE3\fP extension came later:
+.bP
+In June 1999, \fBxterm\fP provided an extension to the standard control
+sequence for clearing the screen.
+Rather than clearing just the visible part of the screen using
+.NS
+printf '\\033[2J'
+.NE
+.IP
+one could clear the \fIscrollback\fP using
+.NS
+printf '\\033[\fB3\fPJ'
+.NE
+.IP
+This is documented in \fIXTerm Control Sequences\fP as a feature originating
+with \fBxterm\fP.
+.bP
+A few other terminal developers adopted the feature, e.g., PuTTY in 2006.
+.bP
+In April 2011, a Red Hat developer submitted a patch to the Linux
+kernel, modifying its console driver to do the same thing.
+The Linux change, part of the 3.0 release, did not mention \fBxterm\fP,
+although it was cited in the Red Hat bug report (#683733)
+which led to the change.
+.bP
+Again, a few other terminal developers adopted the feature.
+But the
+next relevant step was a change to the \fBclear\fP program in 2013
+to incorporate this extension.
+.bP
+In 2013, the \fBE3\fP extension was overlooked in \fB@TPUT@\fP with
+the \*(``clear\*('' parameter.
+That was addressed in 2016 by reorganizing \fB@TPUT@\fP to share
+its logic with \fB@CLEAR@\fP and \fB@TSET@\fP.
+.SH PORTABILITY
+Neither IEEE Std 1003.1/The Open  Group  Base  Specifications  Issue  7
+(POSIX.1-2008) nor X/Open Curses Issue 7 documents @TSET@ or @RESET@.
+.PP
+The latter documents \fBtput\fP, which could be used to replace this utility
+either via a shell script or by an alias (such as a symbolic link) to
+run \fB@TPUT@\fP as \fB@CLEAR@\fP.
+.SH SEE ALSO

+.SH DESCRIPTION
+.SS add_wch
+.PP
+The
+\fBadd_wch\fP,
+\fBwadd_wch\fP,
+\fBmvadd_wch\fP, and
+\fBmvwadd_wch\fP
+functions put the complex character \fIwch\fP into the given
+window at its current position,
+which is then advanced.
+These functions perform
+wrapping and special-character processing as follows:
+.bP
+If \fIwch\fP refers to a spacing character,
+then any previous character at that location is removed.
+A new character specified by \fIwch\fP is
+placed at that location with rendition specified by \fIwch\fP.
+The cursor then advances to
+the next spacing character on the screen.
+.bP
+If \fIwch\fP refers to a non-spacing character,
+all previous characters at that location are preserved.
+The non-spacing characters of \fIwch\fP
+are added to the spacing complex character,
+and the rendition specified by \fIwch\fP is ignored.
+.bP
+If the character part of \fIwch\fP is
+a tab, newline, backspace or other control character,
+the window is updated and the cursor moves as if \fBaddch\fP were called.
+.SS echo_wchar
+.PP
+The \fBecho_wchar\fP
+function is functionally equivalent to a call to
+\fBadd_wch\fP
+followed by a call to
+\fBrefresh\fP(3X).
+Similarly, the
+\fBwecho_wchar\fP
+is functionally equivalent to a call to
+\fBwadd_wch\fP
+followed by a call to
+\fBwrefresh\fP.
+The knowledge
+that only a single character is being output is taken into consideration and,
+for non-control characters, a considerable performance gain might be seen
+by using the *\fBecho\fP* functions instead of their equivalents.
+.SS Line Graphics
+Like \fBaddch\fP(3X),
+\fBaddch_wch\fP accepts symbols which make it simple to draw lines and other
+frequently used special characters.
+These symbols correspond to the same VT100 line-drawing set as
+\fBaddch\fP(3X).

+.SH RETURN VALUE
+.PP
+All routines return the integer \fBERR\fP upon failure and \fBOK\fP on success.
+.PP
+X/Open does not define any error conditions.
+This implementation returns an error
+.bP
+if the window pointer is null or
+.bP
+if it is not possible to add a complete character in the window.
+.PP
+The latter may be due to different causes:
+.bP
+If \fBscrollok\fP is not enabled,
+writing a character at the lower right margin succeeds.
+However, an error is returned because
+it is not possible to wrap to a new line
+.bP
+If an error is detected when converting a multibyte character to a sequence
+of bytes,
+or if it is not possible to add all of the resulting bytes in the window,
+an error is returned.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH NOTES
+.PP
+Note that
+\fBadd_wch\fP,
+\fBmvadd_wch\fP,
+\fBmvwadd_wch\fP, and
+\fBecho_wchar\fP
+may be macros.
+.SH PORTABILITY
+.PP
+All of these functions are described in the XSI Curses standard, Issue 4.
+The defaults specified for line-drawing characters apply in the POSIX locale.
+.PP
+X/Open Curses makes it clear that the WACS_ symbols should be defined as
+a pointer to \fBcchar_t\fP data, e.g., in the discussion of \fBborder_set\fP.
+A few implementations are problematic:
+.bP
+NetBSD curses defines the symbols as a \fBwchar_t\fP within a \fBcchar_t\fP.
+.bP
+HPUX curses equates some of the \fBACS_\fP symbols
+to the analogous \fBWACS_\fP symbols as if the \fBACS_\fP symbols were
+wide characters.
+The misdefined symbols are the arrows
+and other symbols which are not used for line-drawing.
+.PP
+X/Open Curses does not define symbols for thick- or double-lines.
+SVr4 curses implementations defined their line-drawing symbols in
+terms of intermediate symbols.
+This implementation extends those symbols, providing new definitions
+which are not in the SVr4 implementations.
+.PP
+Not all Unicode-capable terminals provide support for VT100-style
+alternate character sets (i.e., the \fBacsc\fP capability),
+with their corresponding line-drawing characters.
+X/Open Curses did not address the aspect of integrating Unicode with
+line-drawing characters.
+Existing implementations of Unix curses (AIX, HPUX, Solaris)
+use only the \fBacsc\fP character-mapping to provide this feature.
+As a result, those implementations can only use single-byte line-drawing
+characters.
+Ncurses 5.3 (2002) provided a table of Unicode values to solve these problems.
+NetBSD curses incorporated that table in 2010.
+.PP
+In this implementation, the Unicode values are used instead of the
+terminal description's \fBacsc\fP mapping as discussed in ncurses(3X)
+for the environment variable \fBNCURSES_NO_UTF8_ACS\fP.
+In contrast, for the same cases, the line-drawing characters
+described in \fBcurs_addch\fP(3X) will use only the ASCII default values.
+.PP
+Having Unicode available does not solve all of the problems with
+line-drawing for curses:
+.bP
+The closest Unicode equivalents to the
+VT100 graphics \fIS1\fP, \fIS3\fP, \fIS7\fP and \fIS9\fP
+frequently are not displayed at
+the regular intervals which the terminal used.
+.bP
+The \fIlantern\fP is a special case.
+It originated with the AT&T 4410 terminal in the early 1980s.
+There is no accessible documentation depicting the lantern symbol
+on the AT&T terminal.
+.IP
+Lacking documentation, most readers assume that a \fIstorm lantern\fP
+was intended.
+But there are several possibilities, all with problems.
+.IP
+Unicode 6.0 (2010) does provide two lantern symbols: U+1F383 and U+1F3EE.
+Those were not available in 2002, and are irrelevant since
+they lie outside the BMP and as a result are not generally available
+in terminals.
+They are not storm lanterns, in any case.
+.IP
+Most \fIstorm lanterns\fP have a tapering glass chimney
+(to guard against tipping);
+some have a wire grid protecting the chimney.
+.IP
+For the tapering appearance, \[u2603] U+2603 was adequate.
+In use on a terminal, no one can tell what the image represents.
+Unicode calls it a snowman.
+.IP
+Others have suggested these alternatives:
+\[sc] U+00A7 (section mark),
+\[u0398] U+0398 (theta),
+\[u03A6] U+03A6 (phi),
+\[u03B4] U+03B4 (delta),
+\[u2327] U+2327 (x in a rectangle),
+\[u256C] U+256C (forms double vertical and horizontal), and
+\[u2612] U+2612 (ballot box with x).

+.SH DESCRIPTION
+These functions copy the (null-terminated)
+array of complex characters \fIwchstr\fP
+into the window image structure
+starting at the current cursor position.
+The four functions with \fIn\fP as the last
+argument copy at most \fIn\fP elements,
+but no more than will fit on the line.
+If \fBn\fP=\fB\-1\fP then the whole array is copied,
+to the maximum number of characters that will fit on the line.
+.PP
+The window cursor is \fInot\fP advanced.
+These functions work faster than \fBwaddnstr\fP.
+On the other hand:
+.bP
+they do not perform checking
+(such as for the newline, backspace, or carriage return characters),
+.bP
+they do not advance the current cursor position,
+.bP
+they do not expand other control characters to ^-escapes, and
+.bP
+they truncate the string if it crosses the right margin,
+rather than wrapping it around to the new line.
+.PP
+These functions end successfully
+on encountering a null \fBcchar_t\fP, or
+when they have filled the current line.
+If a complex character cannot completely fit at the end of the current line,
+the remaining columns are filled with the background character and rendition.
+.SH RETURN VALUE
+All functions return the integer \fBERR\fP upon failure and \fBOK\fP on success.
+.PP
+X/Open does not define any error conditions.
+This implementation returns an error
+if the window pointer is null.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH NOTES
+All functions except \fBwadd_wchnstr\fP may be macros.

+.br
+.SH DESCRIPTION
+.SS Adding characters
+The \fBaddch\fP, \fBwaddch\fP, \fBmvaddch\fP and \fBmvwaddch\fP routines put
+the character \fIch\fP into the given window at its current window position,
+which is then advanced.
+They are analogous to \fBputchar\fP(3) in \fBstdio\fP(3).
+If the advance is at the right margin:
+.bP
+The cursor automatically wraps to the beginning of the next line.
+.bP
+At the bottom of the current scrolling region,
+and if \fBscrollok\fP is enabled,
+the scrolling region is scrolled up one line.
+.bP
+If \fBscrollok\fP is not enabled,
+writing a character at the lower right margin succeeds.
+However, an error is returned because
+it is not possible to wrap to a new line
+.PP
+If \fIch\fP is a tab, newline, carriage return or backspace,
+the cursor is moved appropriately within the window:
+.bP
+Backspace moves the cursor one character left; at the left
+edge of a window it does nothing.
+.bP
+Carriage return moves the cursor to the window left margin on the current line.
+.bP
+Newline does a \fBclrtoeol\fP,
+then moves the cursor to the window left margin on the next line,
+scrolling the window if on the last line.
+.bP
+Tabs are considered to be at every eighth column.
+The tab interval may be altered by setting the \fBTABSIZE\fP variable.
+.PP
+If \fIch\fP is any other nonprintable character,
+it is drawn in printable form,
+i.e., the \fB^\fIX\fR notation used by \fBunctrl\fR(3X).
+Calling \fBwinch\fP after adding a
+nonprintable character does not return the character itself,
+but instead returns the printable representation of the character.
+.PP
+Video attributes can be combined with a character argument passed to
+\fBaddch\fP or related functions by logical-ORing them into the character.
+(Thus, text, including attributes, can be copied from one place to another
+using \fBinch\fP(3X) and \fBaddch\fP.)  See the \fBcurs_attr\fP(3X) page for
+values of predefined video attribute constants that can be usefully OR'ed
+into characters.
+.SS Echoing characters
+.PP
+The \fBechochar\fP and \fBwechochar\fP routines are equivalent to a call to
+\fBaddch\fP followed by a call to \fBrefresh\fP(3X), or a call to \fBwaddch\fP
+followed by a call to \fBwrefresh\fP.
+The knowledge that only a single
+character is being output is used and, for non-control characters, a
+considerable performance gain may be seen by using these routines instead of
+their equivalents.
+.SS Line Graphics
+The following variables may be used to add line drawing characters to the
+screen with routines of the \fBaddch\fP family.
+The default character listed
+below is used if the \fBacsc\fP capability does not define a terminal-specific
+replacement for it,
+or if the terminal and locale configuration requires Unicode but the
+library is unable to use Unicode.
+.PP
+The names are taken from VT100 nomenclature.

+\fBechochar\fP may be macros.
+.SH PORTABILITY
+All these functions are described in the XSI Curses standard, Issue 4.
+The defaults specified for forms-drawing characters apply in the POSIX locale.
+.SS ACS Symbols
+.LP
+X/Open Curses states that the \fBACS_\fP definitions are \fBchar\fP constants.
+For the wide-character implementation (see \fBcurs_add_wch\fP),
+there are analogous \fBWACS_\fP definitions which are \fBcchar_t\fP constants.
+Some implementations are problematic:
+.bP
+Some implementations define the ACS symbols to a constant
+(such as Solaris), while others define those to entries in an array.
+.IP
+This implementation uses an array \fBacs_map\fP, as done in SVr4 curses.
+NetBSD also uses an array, actually named \fB_acs_char\fP, with a \fB#define\fP
+for compatibility.
+.bP
+HPUX curses equates some of the \fBACS_\fP symbols
+to the analogous \fBWACS_\fP symbols as if the \fBACS_\fP symbols were
+wide characters.
+The misdefined symbols are the arrows
+and other symbols which are not used for line-drawing.
+.bP
+X/Open Curses (issues 2 through 7) has a typographical error
+for the ACS_LANTERN symbol, equating its \*(``VT100+ Character\*(''
+to \fBI\fP (capital I), while the header files for SVr4 curses
+and the various implementations use \fBi\fP (lowercase).
+.IP
+None of the terminal descriptions on Unix platforms use uppercase-I,
+except for Solaris (i.e., \fBscreen\fP's terminal description,
+apparently based on the X/Open documentation around 1995).
+On the other hand, the terminal description \fIgs6300\fP
+(AT&T PC6300 with EMOTS Terminal Emulator) uses lowercase-i.
+.LP
+Some ACS symbols
+(ACS_S3,
+ACS_S7,
+ACS_LEQUAL,
+ACS_GEQUAL,
+ACS_PI,
+ACS_NEQUAL,
+ACS_STERLING)
+were not documented in
+any publicly released System V.
+However, many publicly available terminfos
+include \fBacsc\fP strings in which their key characters (pryz{|}) are
+embedded, and a second-hand list of their character descriptions has come
+to light.
+The ACS-prefixed names for them were invented for \fBncurses\fP(3X).
+.LP
+The \fIdisplayed\fP values for the \fBACS_\fP and \fBWACS_\fP constants
+depend on
+.bP
+the library configuration, i.e., \fBncurses\fP versus \fBncursesw\fP,
+where the latter is capable of displaying Unicode while the former is not, and
+.bP
+whether the \fIlocale\fP uses UTF-8 encoding.
+.LP
+In certain cases, the terminal is unable to display line-drawing characters
+except by using UTF-8 (see the discussion of \fBNCURSES_NO_UTF8_ACS\fP in
+ncurses(3X)).
+.SS Character Set
+X/Open Curses assumes that the parameter passed to \fBwaddch\fP contains
+a single character.
+As discussed in \fBcurs_attr\fP(3X), that character may have been
+more than eight bits in an SVr3 or SVr4 implementation,
+but in the X/Open Curses model, the details are not given.
+The important distinction between SVr4 curses and X/Open Curses is
+that the non-character information (attributes and color) was
+separated from the character information which is packed in a \fBchtype\fP
+to pass to \fBwaddch\fP.
+.PP
+In this implementation, \fBchtype\fP holds an eight-bit character.
+But ncurses allows multibyte characters to be passed in a succession
+of calls to \fBwaddch\fP.
+The other implementations do not do this;
+a call to \fBwaddch\fP passes exactly one character
+which may be rendered as one or more cells on the screen
+depending on whether it is printable.
+.PP
+Depending on the locale settings,
+ncurses will inspect the byte passed in each call to \fBwaddch\fP,
+and check if the latest call will continue a multibyte sequence.
+When a character is \fIcomplete\fP,
+ncurses displays the character and moves to the next position in the screen.
+.PP
+If the calling application interrupts the succession of bytes in
+a multibyte character by moving the current location (e.g., using \fBwmove\fP),
+ncurses discards the partially built character,
+starting over again.
+.PP
+For portability to other implementations,
+do not rely upon this behavior:
+.bP
+check if a character can be represented as a single byte in the current locale
+before attempting call \fBwaddch\fP, and
+.bP
+call \fBwadd_wch\fP for characters which cannot be handled by \fBwaddch\fP.
+.SS TABSIZE
+.LP

+.SH DESCRIPTION
+These functions copy the (null-terminated)
+\fIchstr\fP array
+into the window image structure
+starting at the current cursor position.
+The four functions with \fIn\fP as the last
+argument copy at most \fIn\fP elements,
+but no more than will fit on the line.
+If \fBn\fP=\fB\-1\fP then the whole array is copied,
+to the maximum number of characters that will fit on the line.
+.PP
+The window cursor is \fInot\fP advanced.
+These functions work faster than \fBwaddnstr\fP.
+On the other hand:
+.bP
+they do not perform checking
+(such as for the newline, backspace, or carriage return characters),
+.bP
+they do not advance the current cursor position,
+.bP
+they do not expand other control characters to ^-escapes, and
+.bP
+they truncate the string if it crosses the right margin,
+rather than wrapping it around to the new line.
+.SH RETURN VALUE
+All functions return the integer \fBERR\fP upon failure and \fBOK\fP on success.
+.PP
+X/Open does not define any error conditions.
+This implementation returns an error
+if the window pointer is null.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH NOTES

+(e.g.,

+.SH DESCRIPTION
+.PP
+These routines manipulate the current attributes of the named window,
+which then apply to all characters that are written into
+the window with \fBwaddch\fP, \fBwaddstr\fP and \fBwprintw\fP.
+Attributes are
+a property of the character, and move with the character through any scrolling
+and insert/delete line/character operations.
+To the extent possible, they are
+displayed as appropriate modifications to the graphic rendition of characters
+put on the screen.
+.PP
+These routines do not affect the attributes used
+when erasing portions of the window.
+See \fBcurs_bkgd\fP(3X) for functions which modify the attributes used for
+erasing and clearing.
+.PP
+Routines which do not have a \fBWINDOW*\fP parameter apply to \fBstdscr\fP.
+For example,
+\fBattr_set\fP is the \fBstdscr\fP variant of \fBwattr_set\fP.
+.\" ---------------------------------------------------------------------------
+.SS Window attributes
+.PP
+There are two sets of functions:
+.bP
+functions for manipulating the window attributes and color:
+\fBwattr_set\fP and \fBwattr_get\fP.
+.bP
+functions for manipulating only the window attributes (not color):
+\fBwattr_on\fP and \fBwattr_off\fP.
+.PP
+The \fBwattr_set\fP function sets the current attributes
+of the given window to \fIattrs\fP, with color specified by \fIpair\fP.
+.PP
+Use \fBwattr_get\fP to retrieve attributes for the given window.
+.PP
+Use \fBattr_on\fP and \fBwattr_on\fP to turn on window attributes, i.e.,
+values OR'd together in \fIattr\fP,
+without affecting other attributes.
+Use \fBattr_off\fP and \fBwattr_off\fP to turn off window attributes,
+again values OR'd together in \fIattr\fP,
+without affecting other attributes.
+.\" ---------------------------------------------------------------------------
+.SS Legacy window attributes
+The X/Open window attribute routines which \fIset\fP or \fIget\fP,
+turn \fIon\fP or \fIoff\fP
+are extensions of older routines
+which assume that color pairs are OR'd into the attribute parameter.
+These newer routines use similar names, because
+X/Open simply added an underscore (\fB_\fP) for the newer names.
+.PP
+The \fBint\fP datatype used in the legacy routines is treated as if
+it is the same size as \fBchtype\fP (used by \fBaddch\fP(3X)).
+It holds the common video attributes (such as bold, reverse),
+as well as a few bits for color.
+Those bits correspond to the \fBA_COLOR\fP symbol.
+The \fBCOLOR_PAIR\fP macro provides a value which can be OR'd into
+the attribute parameter.
+For example,
+as long as that value fits into the \fBA_COLOR\fP mask,
+then these calls produce similar results:
+.NS
+attrset(A_BOLD | COLOR_PAIR(\fIpair\fP));
+attr_set(A_BOLD, \fIpair\fP, NULL);
+.NE
+.PP
+However, if the value does not fit, then the \fBCOLOR_PAIR\fP macro
+uses only the bits that fit.
+For example, because in ncurses \fBA_COLOR\fP has eight (8) bits,
+then \fBCOLOR_PAIR(\fI259\fB)\fR is 4
+(i.e., 259 is 4 more than the limit 255).
+.PP
+The \fBPAIR_NUMBER\fP macro extracts a pair number from an \fBint\fP
+(or \fBchtype\fP).
+For example, the \fIinput\fP and \fIoutput\fP values in these statements
+would be the same:
+.NS
+int value = A_BOLD | COLOR_PAIR(\fIinput\fP);
+int \fIoutput\fP = PAIR_NUMBER(value);
+.NE
+.PP
+The \fBattrset\fP routine is a legacy feature predating SVr4 curses
+but kept in X/Open Curses for the same reason that SVr4 curses kept it:
+compatibility.
+.PP
+The remaining \fBattr\fP* functions operate exactly like the corresponding
+\fBattr_\fP* functions, except that they take arguments of type \fBint\fP
+rather than \fBattr_t\fP.
+.PP
+There is no corresponding \fBattrget\fP function as such in X/Open Curses,
+although ncurses provides \fBgetattrs\fP (see curs_legacy(3X)).
+.\" ---------------------------------------------------------------------------
+.SS Change character rendition
+.PP
+The routine \fBchgat\fP changes the attributes of a given number of characters
+starting at the current cursor location of \fBstdscr\fP.
+It does not update
+the cursor and does not perform wrapping.
+A character count of \-1 or greater
+than the remaining window width means to change attributes all the way to the
+end of the current line.
+The \fBwchgat\fP function generalizes this to any window;
+the \fBmvwchgat\fP function does a cursor move before acting.
+.PP
+In these functions,
+the color \fIpair\fP argument is a color-pair index
+(as in the first argument of \fBinit_pair\fP, see \fBcurs_color\fP(3X)).
+.\" ---------------------------------------------------------------------------
+.SS Change window color
+The routine \fBcolor_set\fP sets the current color of the given window to the
+foreground/background combination described by the color \fIpair\fP parameter.
+.\" ---------------------------------------------------------------------------
+.SS Standout
+.PP
+The routine \fBstandout\fP is
+the same as \fBattron(A_STANDOUT)\fP.
+The routine \fBstandend\fP is the same
+as \fBattrset(A_NORMAL)\fP or \fBattrset(0)\fP, that is, it turns off all
+attributes.
+.PP
+X/Open does not mark these \*(``restricted\*('', because
+.bP
+they have well established legacy use, and
+.bP
+there is no ambiguity about the way the attributes
+might be combined with a color pair.
+.\" ---------------------------------------------------------------------------
+.SH VIDEO ATTRIBUTES
+The following video attributes, defined in \fB<curses.h>\fP, can be passed to

+.\" ---------------------------------------------------------------------------
+.SH HISTORY
+X/Open Curses is largely based on SVr4 curses,
+adding support for \*(``wide-characters\*('' (not specific to Unicode).
+Some of the X/Open differences from SVr4 curses address the way
+video attributes can be applied to wide-characters.
+But aside from that, \fBattrset\fP and \fBattr_set\fP are similar.
+SVr4 curses provided the basic features for manipulating video attributes.
+However, earlier versions of curses provided a part of these features.
+.PP
+As seen in 2.8BSD, curses assumed 7-bit characters,
+using the eighth bit of a byte to represent the \fIstandout\fP
+feature (often implemented as bold and/or reverse video).
+The BSD curses library provided functions \fBstandout\fP and \fBstandend\fP
+which were carried along into X/Open Curses due to their pervasive use
+in legacy applications.
+.PP
+Some terminals in the 1980s could support a variety of video attributes,
+although the BSD curses library could do nothing with those.
+System V (1983) provided an improved curses library.
+It defined the \fBA_\fP symbols for use by applications to manipulate the
+other attributes.
+There are few useful references for the chronology.
+.PP
+Goodheart's book
+\fIUNIX Curses Explained\fP (1991) describes SVr3 (1987),
+commenting on several functions:
+.bP
+the \fBattron\fP, \fBattroff\fP, \fBattrset\fP functions
+(and most of the functions found in SVr4 but not in BSD curses) were
+introduced by System V,
+.bP
+the alternate character set feature with \fBA_ALTCHARSET\fP was
+added in SVr2 and improved in SVr3 (by adding \fBacs_map[]\fP),
+.bP
+\fBstart_color\fP and related color-functions were introduced by System V.3.2,
+.bP
+pads, soft-keys were added in SVr3, and
+.PP
+Goodheart did not mention the background character or the \fBcchar_t\fP type.
+Those are respectively SVr4 and X/Open features.
+He did mention the \fBA_\fP constants, but did not indicate their values.
+Those were not the same in different systems,
+even for those marked as System V.
+.PP
+Different Unix systems used different sizes for the bit-fields in \fBchtype\fP
+for \fIcharacters\fP and \fIcolors\fP, and took into account the different
+integer sizes (32-bit versus 64-bit).
+.PP
+This table showing the number of bits for \fBA_COLOR\fP
+and \fBA_CHARTEXT\fP
+was gleaned from the curses header files for
+various operating systems and architectures.
+The inferred architecture and notes reflect
+the format and size of the defined constants
+as well as clues such as the alternate character set implementation.
+A 32-bit library can be used on a 64-bit system,
+but not necessarily the reverse.

+.PP
+Regarding HP-UX,
+.bP
+HP-UX 10.20 (1996) added support for 64-bit PA-RISC processors in 1996.
+.bP
+HP-UX 10.30 (1997) marked \*(``curses_colr\*('' obsolete.
+That version of curses was dropped with HP-UX 11.30 in 2006.
+.PP
+Regarding OSF/1 (and Tru64),
+.bP
+These used 64-bit hardware.
+Like ncurses, the OSF/1 curses interface is not customized for 32-bit
+and 64-bit versions.
+.bP
+Unlike other systems which evolved from AT&T code,
+OSF/1 provided a new implementation for X/Open curses.
+.PP
+Regarding Solaris,
+.bP
+The initial release of Solaris was in 1992.
+.bP
+The \fIxpg4\fP (X/Open) curses was developed by MKS from 1990 to 1995.
+Sun's copyright began in 1996.
+.bP
+Sun updated the X/Open curses interface
+after 64-bit support was introduced in 1997,
+but did not modify the SVr4 curses interface.
+.PP
+Regarding U/Win,
+.bP
+Development of the curses library began in 1991, stopped in 2000.
+.bP
+Color support was added in 1998.
+.bP
+The library uses only \fBchtype\fP (no \fBcchar_t\fP).
+.RE
+.PP
+Once X/Open curses was adopted in the mid-1990s, the constraint of
+a 32-bit interface with many colors and wide-characters for \fBchtype\fP
+became a moot point.
+The \fBcchar_t\fP structure (whose size and
+members are not specified in X/Open Curses) could be extended as needed.
+.PP
+Other interfaces are rarely used now:
+.bP
+BSD curses was improved slightly in 1993/1994 using Keith Bostic's
+modification to make the library 8-bit clean for \fBnvi\fP(1).
+He moved \fIstandout\fP attribute to a structure member.
+.IP
+The resulting 4.4BSD curses was replaced by ncurses over the next ten years.
+.bP
+U/Win is rarely used now.
+.\" ---------------------------------------------------------------------------
+.SH EXTENSIONS
+.PP
+This implementation provides the \fBA_ITALIC\fP attribute for terminals
+which have the \fBenter_italics_mode\fP (\fBsitm\fP)
+and \fBexit_italics_mode\fP (\fBritm\fP) capabilities.
+Italics are not mentioned in X/Open Curses.
+Unlike the other video attributes, \fBA_ITALIC\fP is unrelated
+to the \fBset_attributes\fP capabilities.
+This implementation makes the assumption that
+\fBexit_attribute_mode\fP may also reset italics.
+.PP
+Each of the functions added by XSI Curses has a parameter \fIopts\fP,
+which X/Open Curses still (after more than twenty years) documents
+as reserved for future use, saying that it should be \fBNULL\fP.
+This implementation uses that parameter in ABI 6 for the functions which
+have a color-pair parameter to support \fIextended color pairs\fP:
+.bP
+For functions which modify the color, e.g.,
+\fBwattr_set\fP and \fBwattr_on\fP,
+if \fIopts\fP is set it is treated as a pointer to \fBint\fP,
+and used to set the color pair instead of the \fBshort\fP \fIpair\fP parameter.
+.bP
+For functions which retrieve the color, e.g.,
+\fBwattr_get\fP,
+if \fIopts\fP is set it is treated as a pointer to \fBint\fP,
+and used to retrieve the color pair as an \fBint\fP value,
+in addition to
+retrieving it via the standard pointer to \fBshort\fP parameter.
+.bP
+For functions which turn attributes off, e.g.,
+\fBwattr_off\fP,
+the \fIopts\fP parameter is ignored except
+except to check that it is \fBNULL\fP.
+.\" ---------------------------------------------------------------------------
+.SH PORTABILITY
+These functions are supported in the XSI Curses standard, Issue 4.
+The standard defined the dedicated type for highlights,
+\fBattr_t\fP, which was not defined in SVr4 curses.
+The functions taking \fBattr_t\fP arguments were not supported under SVr4.
+.PP
+Very old versions of this library did not force an update of the screen
+when changing the attributes.
+Use \fBtouchwin\fP to force the screen to match the updated attributes.
+.PP
+The XSI Curses standard states that whether the traditional functions
+\fBattron\fP/\fBattroff\fP/\fBattrset\fP can manipulate attributes other than
+\fBA_BLINK\fP, \fBA_BOLD\fP, \fBA_DIM\fP, \fBA_REVERSE\fP, \fBA_STANDOUT\fP, or
+\fBA_UNDERLINE\fP is \*(``unspecified\*(''.
+Under this implementation as well as
+SVr4 curses, these functions correctly manipulate all other highlights
+(specifically, \fBA_ALTCHARSET\fP, \fBA_PROTECT\fP, and \fBA_INVIS\fP).

+.PP
+XSI curses does not assign values to these symbols,
+nor does it state whether or not they are related to the
+similarly-named A_NORMAL, etc.:
+.bP
+The XSI curses standard specifies that each pair of corresponding \fBA_\fP
+and \fBWA_\fP-using functions operates on the same current-highlight
+information.
+.bP
+However, in some implementations, those symbols have unrelated values.
+.IP
+For example, the Solaris \fIxpg4\fP (X/Open) curses declares
+\fBattr_t\fP to be an unsigned short integer (16-bits),
+while \fBchtype\fP is a unsigned integer (32-bits).
+The \fBWA_\fP symbols in this case are different from the \fBA_\fP symbols
+because they are used for a smaller datatype which does not
+represent \fBA_CHARTEXT\fP or \fBA_COLOR\fP.
+.IP
+In this implementation (as in many others), the values happen to be
+the same because it simplifies copying information between
+\fBchtype\fP and \fBcchar_t\fP variables.
+.bP
+Because ncurses's \fBattr_t\fP can hold a color pair
+(in the \fBA_COLOR\fP field),
+a call to
+\fBwattr_on\fP,
+\fBwattr_off\fP, or
+\fBwattr_set\fP
+may alter the window's color.
+If the color pair information in the attribute parameter is zero,
+no change is made to the window's color.
+.IP
+This is consistent with SVr4 curses;
+X/Open Curses does not specify this.
+.PP
+The XSI standard extended conformance level adds new highlights
+\fBA_HORIZONTAL\fP, \fBA_LEFT\fP, \fBA_LOW\fP, \fBA_RIGHT\fP, \fBA_TOP\fP,
+\fBA_VERTICAL\fP (and corresponding \fBWA_\fP macros for each).
+As of August 2013,
+no known terminal provides these highlights
+(i.e., via the \fBsgr1\fP capability).

+\fBint beep(void);\fP
+.br
+\fBint flash(void);\fP
+.br
+.SH DESCRIPTION
+The \fBbeep\fP and \fBflash\fP routines are used to alert the terminal user.
+The routine \fBbeep\fP sounds an audible alarm on the terminal, if possible;
+otherwise it flashes the screen (visible bell).
+The routine \fBflash\fP
+flashes the screen, and if that is not possible, sounds the alert.
+If neither
+alert is possible, nothing happens.
+Nearly all terminals have an audible alert
+(bell or beep), but only some can flash the screen.
+.SH RETURN VALUE
+These routines return \fBOK\fP if they succeed in beeping or flashing,
+\fBERR\fP otherwise.
+.SH EXTENSIONS
+SVr4's beep and flash routines always returned \fBOK\fP, so it was not
+possible to tell when the beep or flash failed.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+Like SVr4, it specifies that they always return \fBOK\fP.

+\fBgetbkgd\fP \- \fBcurses\fP window background manipulation routines
+.SH SYNOPSIS

+.br
+.SH DESCRIPTION
+.SS bkgdset
+The \fBbkgdset\fP and \fBwbkgdset\fP routines
+set the \fIbackground\fP for a window.
+A window's background is a \fBchtype\fP consisting of
+any combination of attributes (i.e., rendition) and a character:
+.bP
+The attribute part of the background is combined (OR'ed) with all non-blank
+characters that are written into the window with \fBwaddch\fP.
+.bP
+Both the character and attribute parts of the background are combined with
+blank characters that are written into the window.
+.PP
+The background becomes a property of each
+character and moves with the character through any scrolling and
+insert/delete line/character operations.
+.PP
+To the extent possible on a particular terminal,
+the attribute part of the background is displayed
+as the graphic rendition of the character put on the screen.
+.SS bkgd
+.PP
+The \fBbkgd\fP and \fBwbkgd\fP functions
+set the background property of the current or specified window
+and then apply this setting to every character position in that window.
+According to X/Open Curses, it should do this:
+.PP
+.bP
+The rendition of every character on the screen is changed to
+the new background rendition.
+.bP
+Wherever the former background character
+appears, it is changed to the new background character.
+.PP
+Neither X/Open Curses nor the SVr4 manual pages give details about
+the way the rendition of characters on the screen is updated when
+\fBbkgd\fP or \fBwbkgd\fP is used to change the background character.
+.PP
+This implementation, like SVr4 curses, does not store the background
+and window attribute contributions to each cell separately.
+It updates the rendition by comparing the character, non-color attributes and
+colors contained in the background.
+For each cell in the window, whether or not it is blank:
+.bP
+The library first compares the \fIcharacter\fP,
+and if it matches the current character part of the background,
+it replaces that with the new background character.
+.IP
+When \fBbkgdset\fP is used to set the background character,
+that does not update each cell in the window.
+A subsequent call to \fBbkgd\fP will only modify the \fIcharacter\fP in
+cells which match the current background character.
+.bP
+The library then checks if the cell uses color,
+i.e., its color pair value is nonzero.
+If not, it simply replaces the attributes and color pair in the
+cell with those from the new background character.
+.bP
+If the cell uses color,
+and that matches the color in the current background,
+the library removes attributes
+which may have come from the current background
+and adds attributes from the new background.
+It finishes by setting the cell
+to use the color from the new background.
+.bP
+If the cell uses color,
+and that does not match the color in the current background,
+the library updates only the non-color attributes,
+first removing those which may have come from the current background,
+and then adding attributes from the new background.
+.PP
+If the background's character value is zero (0), a space is assumed.
+.PP
+If the terminal does not support color,
+or if color has not been started with \fBstart_color\fP,
+the new background character's color attribute will be ignored.
+.SS getbkgd
+.PP
+The \fBgetbkgd\fP function returns the given window's current background
+character/attribute pair.
+.SH RETURN VALUE
+.PP
+These functions are described in the XSI Curses standard, Issue 4.
+It specifies that \fBbkgd\fP and \fBwbkgd\fP return \fBERR\fP on failure,
+but gives no failure conditions.
+.PP
+The routines \fBbkgd\fP and \fBwbkgd\fP return the integer \fBOK\fP,
+unless the library has not been initialized.
+.PP
+In contrast,
+the SVr4.0 manual says \fBbkgd\fP and \fBwbkgd\fP may return \fBOK\fP
+"or a non-negative integer if \fBimmedok\fP is set",
+which refers to the return value from \fBwrefresh\fP
+(used to implement the immediate repainting).
+The SVr4 curses \fBwrefresh\fP returns the number of characters
+written to the screen during the refresh.
+This implementation does not do that.
+.SH NOTES
+.PP
+Note that \fBbkgdset\fP and \fBbkgd\fP may be macros.
+.PP
+X/Open Curses mentions that the character part of the background must
+be a single-byte value.
+This implementation, like SVr4, checks to ensure that,
+and will reuse the old background character if the check fails.
+.SH PORTABILITY
+.PP
+These functions are described in the XSI Curses standard, Issue 4
+(X/Open Curses).

+The \fBgetbkgrnd\fP function returns the given window's current background
+character/attribute pair via the \fBwch\fP pointer.

+The \fBbkgrndset\fP and \fBwbkgrndset\fP routines do not return a value.
+.PP
+Upon successful completion, the other functions return \fBOK\fP.
+Otherwise, they return \fBERR\fP:

+.PP
+The
+\fBborder_set\fP
+and
+\fBwborder_set\fP
+functions draw a border around the edges of the current or specified window.
+These functions do not change the cursor position, and do not wrap.
+.PP
+Other than the window, each argument is a complex character with attributes:
+.RS
+\fIls\fP \- left side,
+.br
+\fIrs\fP \- right side,
+.br
+\fIts\fP \- top side,
+.br
+\fIbs\fP \- bottom side,
+.br
+\fItl\fP \- top left-hand corner,
+.br
+\fItr\fP \- top right-hand corner,
+.br
+\fIbl\fP \- bottom left-hand corner, and
+.br
+\fIbr\fP \- bottom right-hand corner.
+.RE
+.PP
+If any of these arguments is zero, then the corresponding
+default values (defined in \fBcurses.h\fP) are used instead:

+\fBwborder_set(\fIwin\fB, \fIverch\fB, \fIverch\fB,\fR
+    \fIhorch\fB, \fIhorch\fB, NULL, NULL, NULL, NULL);\fR
+.PP
+The
+\fB*line_set\fP
+functions use
+\fIwch\fP
+to draw a line starting at the current cursor position in the window.
+The line is at most \fIn\fP characters long or as many as fit into the window.
+The current cursor position is not changed.
+.PP
+The
+\fBhline_set\fP,
+\fBmvhline_set\fP,
+\fBmvwhline_set\fP, and
+\fBwhline_set\fP

+\fBmvwvline_set\fP, and
+\fBwvline_set\fP

+may be macros.
+.br
+.SH RETURN VALUE
+.PP
+Upon successful completion, these functions return
+\fBOK\fP.
+Otherwise, they return
+\fBERR\fP.
+.PP
+Functions using a window parameter return an error if it is null.

+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.

+.SH DESCRIPTION
+.SS erase/werase
+The \fBerase\fP and \fBwerase\fP routines copy blanks to every
+position in the window, clearing the screen.
+.PP
+Blanks created by erasure have the current background rendition (as set
+by \fBwbkgdset\fP(3X)) merged into them.
+.SS clear/wclear
+.PP
+The \fBclear\fP and \fBwclear\fP routines are like \fBerase\fP and
+\fBwerase\fP, but they also call \fBclearok\fP(3X), so that the screen is
+cleared completely on the next call to \fBwrefresh\fP for that window
+and repainted from scratch.
+.SS clrtobot/wclrtobot
+.PP
+The \fBclrtobot\fP and \fBwclrtobot\fP routines erase from the cursor to the
+end of screen.
+That is, they erase all lines below the cursor in the window.
+Also, the current line to the right of the cursor, inclusive, is erased.
+.SS clrtoeol/wclrtoeol
+.PP
+The \fBclrtoeol\fP and \fBwclrtoeol\fP routines erase the current line
+to the right of the cursor, inclusive, to the end of the current line.
+.SH RETURN VALUE
+All routines return the integer \fBOK\fP on success and \fBERR\fP on failure.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+.bP
+functions using a window pointer parameter return an error if it is null
+.bP
+\fBwclrtoeol\fP returns an error
+if the cursor position is about to wrap.
+.SH NOTES
+Note that \fBerase\fP, \fBwerase\fP, \fBclear\fP, \fBwclear\fP,
+\fBclrtobot\fP, and \fBclrtoeol\fP may be macros.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+The
+standard specifies that they return \fBERR\fP on failure, but specifies no
+error conditions.
+.PP
+The SVr4.0 manual says that these functions could
+return "a non-negative integer if \fBimmedok\fP(3X) is set",
+referring to the return-value of \fBwrefresh\fP.
+In that implementation, \fBwrefresh\fP would return a count of
+the number of characters written to the terminal.
+.PP
+Some historic curses implementations had, as an undocumented feature, the
+ability to do the equivalent of \fBclearok(..., 1)\fP by saying
+\fBtouchwin(stdscr)\fP or \fBclear(stdscr)\fP.
+This will not work under
+ncurses.
+.PP
+This implementation, and others such as Solaris,
+sets the current position to 0,0 after erasing
+via \fBwerase\fP and \fBwclear\fP.
+That fact is not documented in other implementations,
+and may not be true of implementations
+which were not derived from SVr4 source.
+.PP
+Not obvious from the description,
+most implementations clear the screen after \fBwclear\fP
+even for a subwindow or derived window.
+If you do not want to clear the screen during the next \fBwrefresh\fP,
+use \fBwerase\fP instead.

+.SH DESCRIPTION
+.SS Overview
+\fBcurses\fP supports color attributes on terminals with that capability.
+To use these routines \fBstart_color\fP must be called, usually right after
+\fBinitscr\fP.
+Colors are always used in pairs (referred to as color-pairs).
+A color-pair consists of a foreground color (for characters) and a background
+color (for the blank field on which the characters are displayed).
+A programmer initializes a color-pair with the routine \fBinit_pair\fP.
+After it has been initialized, \fBCOLOR_PAIR\fP(\fIn\fP)
+can be used to convert the pair to a video attribute.
+.PP
+If a terminal is capable of redefining colors, the programmer can use the
+routine \fBinit_color\fP to change the definition of a color.
+The routines \fBhas_colors\fP and \fBcan_change_color\fP
+return \fBTRUE\fP or \fBFALSE\fP,
+depending on whether the terminal has color capabilities and whether the
+programmer can change the colors.
+The routine \fBcolor_content\fP allows a
+programmer to extract the amounts of red, green, and blue components in an
+initialized color.
+The routine \fBpair_content\fP allows a programmer to find
+out how a given color-pair is currently defined.
+.SS Color Rendering
+The \fBcurses\fP library combines these inputs to produce the
+actual foreground and background colors shown on the screen:
+.bP
+per-character video attributes (e.g., via \fBwaddch\fP),
+.bP
+the window attribute (e.g., by \fBwattrset\fP), and
+.bP
+the background character (e.g., \fBwbkgdset\fP).
+.PP
+Per-character and window attributes are usually set by a parameter containing
+video attributes including a color pair value.
+Some functions such as \fBwattr_set\fP use a separate parameter which
+is the color pair number.
+.PP
+The background character is a special case: it includes a character value,
+just as if it were passed to \fBwaddch\fP.
+.PP
+The \fBcurses\fP library does the actual work of combining these color
+pairs in an internal function called from \fBwaddch\fP:
+.bP
+If the parameter passed to \fBwaddch\fP is \fIblank\fP,
+and it uses the special color pair 0,
+.RS
+.bP
+\fBcurses\fP next checks the window attribute.
+.bP
+If the window attribute does not use color pair 0,
+\fBcurses\fP uses the color pair from the window attribute.
+.bP
+Otherwise, \fBcurses\fP uses the background character.
+.RE
+.bP
+If the parameter passed to \fBwaddch\fP is \fInot blank\fP,
+or it does not use the special color pair 0,
+\fBcurses\fP prefers the color pair from the parameter,
+if it is nonzero.
+Otherwise, it tries the window attribute next, and finally the
+background character.
+.PP
+Some \fBcurses\fP functions such as \fBwprintw\fP call \fBwaddch\fP.
+Those do not combine its parameter with a color pair.
+Consequently those calls use only the window attribute or
+the background character.
+.SH CONSTANTS
+.PP
+In \fB<curses.h>\fP the following macros are defined.
+These are the standard colors (ISO-6429).
+\fBcurses\fP also assumes that \fBCOLOR_BLACK\fP is the default
+background color for all terminals.
+.PP
+.nf
+      \fBCOLOR_BLACK\fP
+      \fBCOLOR_RED\fP
+      \fBCOLOR_GREEN\fP
+      \fBCOLOR_YELLOW\fP
+      \fBCOLOR_BLUE\fP
+      \fBCOLOR_MAGENTA\fP
+      \fBCOLOR_CYAN\fP
+      \fBCOLOR_WHITE\fP
+.fi
+.PP
+Some terminals support more than the eight (8) \*(``ANSI\*('' colors.
+There are no standard names for those additional colors.
+.SH VARIABLES
+.SS COLORS
+is initialized by \fBstart_color\fP to the maximum number of colors
+the terminal can support.
+.SS COLOR_PAIRS
+is initialized by \fBstart_color\fP to the maximum number of color pairs
+the terminal can support.
+.SH FUNCTIONS
+.SS start_color
+The \fBstart_color\fP routine requires no arguments.
+It must be called if the programmer wants to use colors, and before any other
+color manipulation routine is called.
+It is good practice to call this routine right after \fBinitscr\fP.
+\fBstart_color\fP does this:
+.bP
+It initializes two global variables, \fBCOLORS\fP and
+\fBCOLOR_PAIRS\fP (respectively defining the maximum number of colors
+and color-pairs the terminal can support).
+.bP
+It initializes the special color pair \fB0\fP to the default foreground
+and background colors.
+No other color pairs are initialized.
+.bP
+It restores the colors on the terminal to the values
+they had when the terminal was just turned on.
+.bP
+If the terminal supports the \fBinitc\fP (\fBinitialize_color\fP) capability,
+\fBstart_color\fP
+initializes its internal table representing the
+red, green, and blue components of the color palette.
+.IP
+The components depend on whether the terminal uses
+CGA (aka \*(``ANSI\*('') or
+HLS (i.e., the \fBhls\fP (\fBhue_lightness_saturation\fP) capability is set).
+The table is initialized first for eight basic colors
+(black, red, green, yellow, blue, magenta, cyan, and white),
+using weights that depend upon the CGA/HLS choice.
+For \*(``ANSI\*('' colors the weights are \fB680\fP or \fB0\fP
+depending on whether the corresponding
+red, green, or blue component is used or not.
+That permits using \fB1000\fP to represent bold/bright colors.
+After the initial eight colors
+(if the terminal supports more than eight colors)
+the components are initialized using the same pattern,
+but with weights of \fB1000\fP.
+SVr4 uses a similar scheme, but uses \fB1000\fP
+for the components of the initial eight colors.
+.IP
+\fBstart_color\fP does not attempt to set the terminal's color palette
+to match its built-in table.
+An application may use \fBinit_color\fP to alter the internal table
+along with the terminal's color.
+.PP
+These limits apply to color values and color pairs.
+Values outside these limits are not legal, and may result in a runtime error:
+.bP
+\fBCOLORS\fP corresponds to the terminal database's \fBmax_colors\fP capability,
+(see \fBterminfo\fP(\*n)).
+.bP
+color values are expected to be in the range \fB0\fP to \fBCOLORS\-1\fP,
+inclusive (including \fB0\fP and \fBCOLORS\-1\fP).
+.bP
+a special color value \fB\-1\fP is used in certain extended functions
+to denote the \fIdefault color\fP (see \fBuse_default_colors\fP(3X)).
+.bP
+\fBCOLOR_PAIRS\fP corresponds to
+the terminal database's \fBmax_pairs\fP capability,
+(see \fBterminfo\fP(\*n)).
+.bP
+legal color pair values are in the range \fB1\fP to \fBCOLOR_PAIRS\-1\fP,
+inclusive.
+.bP
+color pair \fB0\fP is special; it denotes \*(``no color\*(''.
+.IP
+Color pair \fB0\fP is assumed to be white on black,
+but is actually whatever the terminal implements before color is initialized.
+It cannot be modified by the application.
+.SS has_colors
+.PP
+The \fBhas_colors\fP routine requires no arguments.
+It returns \fBTRUE\fP if
+the terminal can manipulate colors; otherwise, it returns \fBFALSE\fP.
+This routine facilitates writing terminal-independent programs.
+For example, a programmer can use it to decide
+whether to use color or some other video attribute.
+.SS can_change_color
+.PP
+The \fBcan_change_color\fP routine requires no arguments.
+It returns \fBTRUE\fP if the terminal supports colors
+and can change their definitions;
+other, it returns \fBFALSE\fP.
+This routine facilitates writing terminal-independent programs.
+.SS init_pair
+.PP
+The \fBinit_pair\fP routine changes the definition of a color-pair.
+It takes three arguments:
+the number of the color-pair to be changed, the foreground
+color number, and the background color number.
+For portable applications:
+.bP
+The first argument must be a legal color pair value.
+If default colors are used (see \fBuse_default_colors\fP(3X))
+the upper limit is adjusted to allow for extra pairs which use
+a default color in foreground and/or background.
+.bP
+The second and third arguments must be legal color values.
+.PP
+If the color-pair was previously initialized,
+the screen is refreshed and all occurrences of that color-pair
+are changed to the new definition.
+.PP
+As an extension, ncurses allows you to set color pair \fB0\fP via
+the \fBassume_default_colors\fP(3X) routine, or to specify the use of
+default colors (color number \fB\-1\fP) if you first invoke the
+\fBuse_default_colors\fP(3X) routine.
+.SS init_extended_pair
+.PP
+Because \fBinit_pair\fP uses signed \fBshort\fPs for its parameters,
+that limits color-pairs and color-values
+to 32767 on modern hardware.
+The extension \fBinit_extended_pair\fP uses \fBint\fPs
+for the color-pair and color-value,
+allowing a larger number of colors to be supported.
+.SS init_color
+.PP
+The \fBinit_color\fP routine changes the definition of a color.
+It takes four arguments:
+the number of the color to be changed followed by three RGB values
+(for the amounts of red, green, and blue components).
+.bP
+The first argument must be a legal color value;
+default colors are not allowed here.
+(See the section \fBColors\fP for the default color index.)
+.bP
+Each of the last three arguments
+must be a value in the range \fB0\fP through \fB1000\fP.
+.PP
+When \fBinit_color\fP is used, all
+occurrences of that color on the screen immediately change to the new
+definition.
+.SS init_extended_color
+.PP
+Because \fBinit_color\fP uses signed \fBshort\fPs for its parameters,
+that limits color-values and their red, green, and blue components
+to 32767 on modern hardware.
+The extension \fBinit_extended_color\fP uses \fBint\fPs
+for the color value and
+for setting the red, green, and blue components,
+allowing a larger number of colors to be supported.
+.SS color_content
+.PP
+The \fBcolor_content\fP routine gives programmers a way to find the intensity
+of the red, green, and blue (RGB) components in a color.
+It requires four arguments: the color number, and three addresses
+of \fBshort\fRs for storing
+the information about the amounts of red, green, and blue components in the
+given color.
+.bP
+The first argument must be a legal color value, i.e.,
+\fB0\fP through \fBCOLORS\-1\fP, inclusive.
+.bP
+The values that are stored at the addresses pointed to by the
+last three arguments are in the range
+\fB0\fP (no component) through \fB1000\fP
+(maximum amount of component), inclusive.
+.SS extended_color_content
+.PP
+Because \fBcolor_content\fP uses signed \fBshort\fPs for its parameters,
+that limits color-values and their red, green, and blue components
+to 32767 on modern hardware.
+The extension \fBextended_color_content\fP uses \fBint\fPs
+for the color value and
+for returning the red, green, and blue components,
+allowing a larger number of colors to be supported.
+.SS pair_content
+.PP
+The \fBpair_content\fP routine allows programmers to find out what colors a
+given color-pair consists of.
+It requires three arguments: the color-pair
+number, and two addresses of \fBshort\fRs for storing the foreground and the
+background color numbers.
+.bP
+The first argument must be a legal color value,
+i.e., in the range \fB1\fP through \fBCOLOR_PAIRS\-1\fP, inclusive.
+.bP
+The values that are stored at the addresses pointed
+to by the second and third arguments are in the
+range \fB0\fP through \fBCOLORS\fP, inclusive.
+.SS extended_pair_content
+.PP
+Because \fBpair_content\fP uses signed \fBshort\fPs for its parameters,
+that limits color-pair and color-values to 32767 on modern hardware.
+The extension \fBextended_pair_content\fP uses \fBint\fPs
+for the color pair and
+for returning the foreground and background colors,
+allowing a larger number of colors to be supported.
+.SS reset_color_pairs
+.PP
+The extension \fBreset_color_pairs\fP tells ncurses to discard all
+of the color-pair information which was set with \fBinit_pair\fP.
+It also touches the current- and standard-screens, allowing an application to
+switch color palettes rapidly.
+.SS PAIR_NUMBER
+.PP
+\fBPAIR_NUMBER(\fIattrs\fR) extracts the color
+value from its \fIattrs\fP parameter and returns it as a color pair number.
+.SS COLOR_PAIR
+Its inverse \fBCOLOR_PAIR(\fIn\fB)\fR converts a color pair number
+to an attribute.
+Attributes can hold color pairs in the range 0 to 255.
+If you need a color pair larger than that, you must use functions
+such as \fBattr_set\fP (which pass the color pair as a separate parameter)
+rather than the legacy functions such as \fBattrset\fP.
+.SH RETURN VALUE
+The routines \fBcan_change_color\fP and \fBhas_colors\fP return \fBTRUE\fP
+or \fBFALSE\fP.
+.PP
+All other routines return the integer \fBERR\fP upon failure and an \fBOK\fP
+(SVr4 specifies only \*(``an integer value
+other than \fBERR\fP\*('') upon successful completion.
+.PP
+X/Open defines no error conditions.
+SVr4 does document some error conditions which apply in general:
+.bP
+This implementation will return \fBERR\fP on attempts to
+use color values outside the range \fB0\fP to \fBCOLORS\fP\-1
+(except for the default colors extension),
+or use color pairs outside the range \fB0\fP to \fBCOLOR_PAIRS\-1\fP.
+.IP
+Color values used in \fBinit_color\fP must be
+in the range \fB0\fP to \fB1000\fP.
+.IP
+An error is returned from all functions
+if the terminal has not been initialized.
+.IP
+An error is returned from secondary functions such as \fBinit_pair\fP
+if \fBstart_color\fP was not called.
+.bP
+SVr4 does much the same, except that
+it returns \fBERR\fP from \fBpair_content\fP if the pair was not initialized
+using \fBinit_pairs\fP
+and
+it returns \fBERR\fP from \fBcolor_content\fP
+if the terminal does not support changing colors.
+.IP
+This implementation does not return \fBERR\fP for either case.
+.PP
+Specific functions make additional checks:
+.RS 3
+.TP 5
+\fBinit_color\fP
+returns an error if the terminal does not support
+this feature, e.g., if the \fBinitialize_color\fP capability is absent
+from the terminal description.
+.TP 5
+\fBstart_color\fP
+returns an error if the color table cannot be allocated.
+.RE
+.SH NOTES
+In the \fBncurses\fP implementation, there is a separate color activation flag,
+color palette, color pairs table,
+and associated \fBCOLORS\fP and \fBCOLOR_PAIRS\fP counts
+for each screen; the \fBstart_color\fP function only affects the current
+screen.
+The SVr4/XSI interface is not really designed with this in mind, and
+historical implementations may use a single shared color palette.
+.PP
+Setting an implicit background color via a color pair affects only
+character cells that a character write operation explicitly touches.
+To change
+the background color used when parts of a window are blanked by erasing or
+scrolling operations, see \fBcurs_bkgd\fP(3X).
+.PP
+Several caveats apply on older x86 machines
+(e.g., i386, i486) with VGA-compatible graphics:
+.bP
+COLOR_YELLOW is actually brown.
+To get yellow, use COLOR_YELLOW combined with the \fBA_BOLD\fP attribute.
+.bP
+The A_BLINK attribute should in theory cause the background to go bright.
+This often fails to work, and even some cards for which it mostly works
+(such as the
+Paradise and compatibles) do the wrong thing when you try to set a bright
+\*(``yellow\*('' background (you get a blinking yellow foreground instead).
+.bP
+Color RGB values are not settable.
+.SH HISTORY
+.PP
+SVr3.2 introduced color support to curses in 1987.
+.PP
+SVr4 made internal changes,
+e.g., moving the storage for the color state
+from \fBSP\fP (the \fBSCREEN\fP structure)
+to \fBcur_term\fP (the \fBTERMINAL\fP structure),
+but provided the same set of library functions.
+.PP
+SVr4 curses limits the number of color pairs to 64,
+reserving color pair zero (0) as the terminal's initial uncolored state.
+This limit arises because the color pair information is a bitfield
+in the \fBchtype\fP data type (denoted by \fBA_COLOR\fP).
+.PP
+Other implementations of curses had different limits:
+.bP
+PCCurses (1987-1990) provided for only eight (8) colors.
+.bP
+PDCurses (1992-present) inherited the 8-color limitation from PCCurses,
+but changed this to 256 in version 2.5 (2001),
+along with changing \fBchtype\fP from 16-bits to 32-bits.
+.bP
+X/Open Curses (1992-present)
+added a new structure \fBcchar_t\fP to store the character,
+attributes and color-pair values, allowing increased range of color-pairs.
+Both color-pairs and color-values used a signed \fBshort\fP,
+limiting values to 15 bits.
+.bP
+ncurses (1992-present) uses eight bits for \fBA_COLOR\fP in \fBchtype\fP values.
+.IP
+Version 5.3 provided a wide-character interface (2002),
+but left color-pairs as part of the attributes-field.
+.IP
+Since version 6 (2015),
+ncurses uses a separate \fBint\fP for color-pairs in the \fBcchar_t\fP values.
+When those color-pair values fit in 8 bits,
+ncurses allows color-pairs to be manipulated
+via the functions using \fBchtype\fP values.
+.bP
+NetBSD curses used 6 bits from
+2000 (when colors were first supported) until 2004.
+At that point, NetBSD changed to use 10 bits.
+As of 2021, that size is unchanged.
+Like ncurses before version 6,
+the NetBSD color-pair information is stored in
+the attributes field of \fBcchar_t\fP, limiting the number of color-pairs
+by the size of the bitfield.
+.SH PORTABILITY
+This implementation satisfies XSI Curses's minimum maximums
+for \fBCOLORS\fP and \fBCOLOR_PAIRS\fP.
+.PP
+The \fBinit_pair\fP routine accepts negative values of foreground
+and background color to support the \fBuse_default_colors\fP(3X) extension,
+but only if that routine has been first invoked.
+.PP
+The assumption that \fBCOLOR_BLACK\fP is the default
+background color for all terminals can be modified using the
+\fBassume_default_colors\fP(3X) extension.
+.PP
+This implementation checks the pointers,
+e.g., for the values returned by
+\fBcolor_content\fP and \fBpair_content\fP,
+and will treat those as optional parameters when null.
+.PP
+X/Open Curses does not specify a limit for the number of colors and
+color pairs which a terminal can support.
+However, in its use of \fBshort\fP for the parameters,
+it carries over SVr4's implementation detail for the compiled
+terminfo database, which uses signed 16-bit numbers.
+This implementation provides extended versions of those functions
+which use \fBshort\fP parameters,
+allowing applications to use larger color- and pair-numbers.
+.PP
+The \fBreset_color_pairs\fP function is an extension of ncurses.

+.SH DESCRIPTION
+These routines delete the character under the cursor; all characters to the
+right of the cursor on the same line are moved to the left one position and the
+last character on the line is filled with a blank.
+The cursor position does
+not change (after moving to \fIy\fP, \fIx\fP, if specified).
+(This does not
+imply use of the hardware delete character feature.)
+.SH RETURN VALUE
+All routines return the integer \fBERR\fP upon failure and an \fBOK\fP (SVr4
+specifies only "an integer value other than \fBERR\fP") upon successful
+completion.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH NOTES
+Note that \fBdelch\fP, \fBmvdelch\fP, and \fBmvwdelch\fP may be macros.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+The
+standard specifies that they return \fBERR\fP on failure, but specifies no
+error conditions.

+.SH NAME
+\fBdeleteln\fP,
+\fBwdeleteln\fP,
+\fBinsdelln\fP,
+\fBwinsdelln\fP,
+\fBinsertln\fP,
+\fBwinsertln\fP \- delete and insert lines in a \fBcurses\fP window
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint deleteln(void);\fP
+.br
+\fBint wdeleteln(WINDOW *\fIwin\fB);\fR
+.sp
+\fBint insdelln(int \fIn\fB);\fR
+.br
+\fBint winsdelln(WINDOW *\fIwin\fB, int \fIn\fB);\fR
+.sp
+\fBint insertln(void);\fP
+.br
+\fBint winsertln(WINDOW *\fIwin\fB);\fR
+.br
+.SH DESCRIPTION
+The \fBdeleteln\fP and \fBwdeleteln\fP routines delete the line under the
+cursor in the window; all lines below the current line are moved up one line.
+The bottom line of the window is cleared.
+The cursor position does not change.
+.PP
+The \fBinsdelln\fP and \fBwinsdelln\fP routines, for positive \fIn\fP, insert
+\fIn\fP lines into the specified window above the current line.
+The \fIn\fP
+bottom lines are lost.
+For negative \fIn\fP, delete \fIn\fP lines (starting
+with the one under the cursor), and move the remaining lines up.
+The bottom
+\fIn\fP lines are cleared.
+The current cursor position remains the same.
+.PP
+The \fBinsertln\fP and \fBwinsertln\fP routines insert a blank line above the
+current line and the bottom line is lost.
+.SH RETURN VALUE
+All routines return the integer \fBERR\fP upon failure and an \fBOK\fP (SVr4
+specifies only "an integer value other than \fBERR\fP") upon successful
+completion.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+if the window parameter is null, an error is returned.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+The
+standard specifies that they return \fBERR\fP on failure, but specifies no
+error conditions.
+.SH NOTES
+Note that all but \fBwinsdelln\fP may be macros.
+.PP
+These routines do not require a hardware line delete or insert feature in the
+terminal.
+In fact, they will not use hardware line delete/insert unless
+\fBidlok(..., TRUE)\fP has been set on the current window.

+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBconst char * curses_version(void);\fP
+.br
+\fBint use_extended_names(bool \fIenable\fB);\fR
+.SH DESCRIPTION
+These functions are extensions to the curses library
+which do not fit easily into other categories.
+.SS curses_version
+.PP
+Use \fBcurses_version\fP
+to get the version number, including patch level of the library,
+prefixed by \*(``ncurses\*('', e.g.,
+.RS
+.sp
+.B ncurses 5.0.19991023
+.RE
+.SS use_extended_names
+.PP
+The \fBuse_extended_names\fP
+function controls whether the calling application
+is able to use user-defined or nonstandard names
+which may be compiled into the terminfo
+description, i.e., via the terminfo or termcap interfaces.
+Normally these names are available for use, since the essential decision
+is made by using the \fB\-x\fP option of \fB@TIC@\fP to compile
+extended terminal definitions.
+However you can disable this feature
+to ensure compatibility with other implementations of curses.
+.SH RETURN VALUE
+.PP
+\fBcurses_version\fP returns a pointer to static memory; you should not free
+this in your application.
+.PP
+\fBuse_extended_names\fP returns the previous state, allowing you to
+save this and restore it.
+.SH PORTABILITY
+These routines are specific to ncurses.
+They were not supported on
+Version 7, BSD or System V implementations.
+It is recommended that
+any code depending on them be conditioned using NCURSES_VERSION.

+.ad
+.hy
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint get_wch(wint_t *\fIwch\fB);\fR
+.br
+\fBint wget_wch(WINDOW *\fIwin\fB, wint_t *\fIwch\fB);\fR

+.sp
+\fBint unget_wch(const wchar_t \fIwch\fB);\fR
+.SH DESCRIPTION
+.SS wget_wch
+The
+\fBget_wch\fP,
+\fBwget_wch\fP,
+\fBmvget_wch\fP, and
+\fBmvwget_wch\fP
+functions read a character
+from the terminal associated with the current or specified window.
+In no-delay mode,
+if no input is waiting, the value \fBERR\fP is returned.
+In delay mode,
+the program waits until the system passes text through to the program.
+Depending on the setting of \fBcbreak\fP,
+this is after one character (cbreak mode),
+or after the first newline (nocbreak mode).
+In half-delay mode,
+the program waits until the user types a character or the specified
+timeout interval has elapsed.
+.PP
+Unless \fBnoecho\fP has been set,
+these routines echo the character into the designated window.
+.PP
+If the window is not a pad and has been moved or modified since the
+last call to \fBwrefresh\fP,
+\fBwrefresh\fP will be called before another character is read.
+.PP
+If \fBkeypad\fP is enabled,
+these functions respond to
+the pressing of a function key by setting the object pointed to by
+\fIwch\fP
+to the keycode assigned to the function key,
+and returning \fBKEY_CODE_YES\fP.
+If a character (such as escape) that could be the
+beginning of a function key is received, curses sets a timer.
+If the remainder
+of the sequence does arrive within the designated time, curses passes through
+the character; otherwise, curses returns the function key value.
+For this
+reason, many terminals experience a delay between the time a user presses
+the escape key and the time the escape is returned to the program.
+.PP
+The keycodes returned by these functions are the same as those
+returned by \fBwgetch\fP:
+.bP
+The predefined function
+keys are listed in \fB<curses.h>\fP as macros with values outside the range
+of 8-bit characters.
+Their names begin with \fBKEY_\fP.
+.bP
+Other (user-defined) function keys
+which may be defined using \fBdefine_key\fP(3X) have no names,
+but also are expected to have values outside the range of 8-bit characters.
+.SS unget_wch
+The
+\fBunget_wch\fP
+function pushes the wide character
+\fIwch\fP
+back onto the head of the input queue, so the wide character
+is returned by the next call to
+\fBget_wch\fP.
+The pushback of
+one character is guaranteed.
+If the program calls
+\fBunget_wch\fP
+too many times without an intervening call to
+\fBget_wch\fP,
+the operation may fail.
+.PP
+Unlike \fBungetch\fP and \fBwgetch\fP,
+\fBunget_wch\fP cannot distinguish special characters
+returned by \fBwget_wch\fP from ordinary characters.
+An application can push special keys
+which it may read via \fBwget_wch\fP
+by checking for the \fBKEY_CODE_YES\fP result,
+and using \fBungetch\fP for those special keys.
+.SH NOTES
+The header file
+\fB<curses.h>\fP
+automatically
+includes the header file
+\fB<stdio.h>\fP.
+.PP
+Applications should not define the escape key by itself as a single-character
+function.
+.PP
+When using
+\fBget_wch\fP,
+\fBwget_wch\fP,
+\fBmvget_wch\fP, or
+\fBmvwget_wch\fP, applications should
+not use
+\fBnocbreak\fP
+mode and
+\fBecho\fP
+mode
+at the same time.
+Depending on the state of the tty driver when each character
+is typed, the program may produce undesirable results.
+.PP
+All functions except \fBwget_wch\fP and \fBunget_wch\fP
+may be macros.
+.SH RETURN VALUE
+When
+\fBget_wch\fP,
+\fBwget_wch\fP,
+\fBmvget_wch\fP, and
+\fBmvwget_wch\fP
+functions successfully
+report the pressing of a function key, they return
+\fBKEY_CODE_YES\fP.
+When they successfully report a wide character, they return
+\fBOK\fP.
+Otherwise, they return
+\fBERR\fP.
+.PP
+Upon successful completion,
+\fBunget_wch\fP
+returns
+\fBOK\fP.
+Otherwise, the function returns
+\fBERR\fP.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.

+.SH DESCRIPTION
+The effect of
+\fBget_wstr\fP
+is as though a series of calls
+to
+\fBget_wch\fP(3X)
+were made, until a newline, other end-of-line,
+or end-of-file condition is processed.
+An end-of-file condition is represented by \fBWEOF\fP,
+as defined in \fB<wchar.h>\fP.
+The newline and end-of-line conditions are represented
+by the \fB\\n\fP \fBwchar_t\fP value.
+In all instances, the end of the string is terminated by a null \fBwchar_t\fP.
+The routine places resulting values in the area pointed to by \fIwstr\fP.
+.PP
+The user's erase and kill characters are interpreted.
+If keypad
+mode is on for the window, \fBKEY_LEFT\fP and \fBKEY_BACKSPACE\fP
+are both considered equivalent to the user's kill character.
+.PP
+Characters input are echoed only if \fBecho\fP is currently on.
+In that case,

+Functions with a \*(``mv\*('' prefix first perform a cursor movement using

+.SH PORTABILITY
+These functions are described in The Single Unix Specification, Version 2.
+No error conditions are defined.
+This implementation returns \fBERR\fP if the window pointer is null,
+or if the lower-level \fBwget_wch\fP call returns an \fBERR\fP.
+In the latter case,
+an \fBERR\fP return without other data is treated as an end-of-file condition,
+and the returned array contains a \fBWEOF\fP followed by a null \fBwchar_t\fP.
+.PP
+X/Open curses documented these functions to pass an array of \fBwchar_t\fP
+in 1997, but that was an error because of this part of the description:
+.RS
+.PP
+The effect of \fBget_wstr\fP is as though a series of calls to
+\fBget_wch\fP were made, until a newline character, end-of-line character, or
+end-of-file character is processed.
+.RE
+.PP
+The latter function \fIget_wch\fP can return a negative value,
+while \fBwchar_t\fP is a unsigned type.
+All of the vendors implement this using \fBwint_t\fP, following the standard.
+.PP
+X/Open Curses, Issue 7 (2009) is unclear regarding whether
+the terminating \fInull \fBwchar_t\fR
+value is counted in the length parameter \fIn\fP.
+X/Open Curses, Issue 7 revised the corresponding description
+of \fBwgetnstr\fP to address this issue.
+The unrevised description of \fBwget_nwstr\fP can be interpreted either way.
+This implementation counts the terminator in the length.
+.PP
+X/Open Curses does not specify what happens if the length \fIn\fP is negative.
+.bP
+For analogy with \fBwgetnstr\fP,
+ncurses 6.2 uses a limit (based on \fBLINE_MAX\fP).
+.bP
+Some other implementations (such as Solaris xcurses) do the same,
+while others (PDCurses) do not allow this.
+.bP
+NetBSD 7 curses imitates ncurses 6.1 in this regard,
+treating a \fB\-1\fP as an indefinite number of characters.

+.SH DESCRIPTION
+.SS getcchar
+.PP
+The \fBgetcchar\fP function gets a wide-character string
+and rendition from a \fBcchar_t\fP argument.
+When \fIwch\fP is not a null pointer,
+the \fBgetcchar\fP function does the following:
+.bP
+Extracts information from a \fBcchar_t\fP value \fIwcval\fP
+.bP
+Stores the character attributes in the location pointed to by \fIattrs\fP
+.bP
+Stores the color-pair in the location pointed to by \fIcolor_pair\fP
+.bP
+Stores the wide-character string,
+characters referenced by \fIwcval\fP, into the array pointed to by \fIwch\fP.
+.PP
+When
+\fIwch\fP
+is a null pointer, the
+\fBgetcchar\fP
+function does the following:
+.bP
+Obtains the number of wide characters pointed to by \fIwcval\fP
+.bP
+Does not change the data referenced by
+\fIattrs\fP
+or
+\fIcolor_pair\fP
+.SS setcchar
+.PP
+The \fBsetcchar\fP function initializes the location pointed to by \fIwcval\fP
+by using:
+.bP
+The character attributes in
+\fIattrs\fP
+.bP
+The color pair in
+\fIcolor_pair\fP
+.bP
+The wide-character string pointed to by \fIwch\fP.
+The string must be L'\\0' terminated,
+contain at most one spacing character,
+which must be the first.
+.IP
+Up to \fBCCHARW_MAX\fP\-1 nonspacing characters may follow.
+Additional nonspacing characters are ignored.
+.IP
+The string may contain a single control character instead.
+In that case, no nonspacing characters are allowed.
+.SH EXTENSIONS
+.PP
+X/Open Curses documents the \fIopts\fP argument as reserved for future use,
+saying that it must be null.
+This implementation
+uses that parameter in ABI 6 for the functions which have a color-pair
+parameter to support extended color pairs:
+.bP
+For  functions  which modify the color, e.g., \fBsetcchar\fP,
+if \fIopts\fP is set it is treated as a pointer to \fBint\fP,
+and used to  set  the  color pair instead of the \fBshort\fP pair parameter.
+.bP
+For functions which retrieve the color, e.g., \fBgetcchar\fP,
+if \fIopts\fP is set it is treated as a pointer to \fBint\fP,
+and  used  to  retrieve  the color pair as an \fBint\fP value,
+in addition retrieving it via the standard pointer to \fBshort\fP parameter.
+.SH NOTES
+.PP
+The \fIwcval\fP argument may be a value generated by a call to
+\fBsetcchar\fP or by a function that has a \fBcchar_t\fP output argument.
+If \fIwcval\fP is constructed by any other means, the effect is unspecified.
+.SH RETURN VALUE
+.PP
+When \fIwch\fP is a null pointer,
+\fBgetcchar\fP returns the number of wide characters referenced by
+\fIwcval\fP,
+including one for a trailing null.
+.PP
+When \fIwch\fP is not a null pointer,
+\fBgetcchar\fP returns \fBOK\fP upon successful completion,
+and \fBERR\fP otherwise.
+.PP
+Upon successful completion, \fBsetcchar\fP returns \fBOK\fP.
+Otherwise, it returns \fBERR\fP.
+.SH PORTABILITY
+The \fBCCHARW_MAX\fP symbol is specific to ncurses.
+X/Open Curses does not provide details for the layout of the \fBcchar_t\fP
+structure.
+It tells what data are stored in it:
+.bP
+a spacing character (\fBwchar_t\fP, i.e., 32-bits).
+.bP
+non-spacing characters (again, \fBwchar_t\fP's).
+.bP
+attributes (at least 16 bits, inferred from the various ACS- and WACS-flags).
+.bP
+color pair (at least 16 bits, inferred from the \fBunsigned short\fP type).
+.PP
+The non-spacing characters are optional,
+in the sense that zero or more may be stored in a \fBcchar_t\fP.
+XOpen/Curses specifies a limit:
+.RS 4
+.PP
+Implementations may limit the number of non-spacing characters that can be
+associated with a spacing character, provided any limit is at least 5.
+.RE
+.PP
+The Unix implementations at the time follow that limit:
+.bP
+AIX\ 4 and OSF1\ 4 use the same declaration with an array of 5 non-spacing
+characters \fIz\fP and a single spacing character \fIc\fP.
+.bP
+HP-UX\ 10 uses an opaque structure with 28 bytes,
+which is large enough for the 6 \fBwchar_t\fP values.
+.bP
+Solaris \fIxpg4\fP curses uses a single array of 6 \fBwchar_t\fP values.
+.PP
+This implementation's \fBcchar_t\fP was defined in 1995
+using \fB5\fP for the total of spacing and non-spacing characters
+(\fBCCHARW_MAX\fP).
+That was probably due to a misreading of the AIX\ 4 header files,
+because the X/Open Curses document was not generally available at that time.
+Later (in 2002), this detail was overlooked when beginning to implement
+the functions using the structure.
+.PP
+In practice, even four non-spacing characters may seem enough.
+X/Open Curses documents possible uses for non-spacing characters,
+including using them for ligatures between characters
+(a feature apparently not supported by any curses implementation).
+Unicode does not limit the (analogous) number of combining characters,
+so some applications may be affected.

+.SH DESCRIPTION
+.SS Reading characters
+The \fBgetch\fP, \fBwgetch\fP, \fBmvgetch\fP and \fBmvwgetch\fP, routines read
+a character from the window.
+In no-delay mode, if no input is waiting, the value \fBERR\fP is returned.
+In delay mode, the program waits until the system
+passes text through to the program.
+Depending on the setting of \fBcbreak\fP,
+this is after one character (cbreak mode),
+or after the first newline (nocbreak mode).
+In half-delay mode,
+the program waits until a character is typed or the
+specified timeout has been reached.
+.PP
+If \fBecho\fP is enabled, and the window is not a pad,
+then the character will also be echoed into the
+designated window according to the following rules:
+.bP
+If the character is the current erase character, left arrow, or backspace,
+the cursor is moved one space to the left and that screen position is erased
+as if \fBdelch\fP had been called.
+.bP
+If the character value is any other \fBKEY_\fP define, the user is alerted
+with a \fBbeep\fP call.
+.bP
+If the character is a carriage-return,
+and if \fBnl\fP is enabled,
+it is translated to a line-feed after echoing.
+.bP
+Otherwise the character is simply output to the screen.
+.PP
+If the window is not a pad, and it has been moved or modified since the last
+call to \fBwrefresh\fP, \fBwrefresh\fP will be called before another character
+is read.
+.SS Keypad mode
+.PP
+If \fBkeypad\fP is \fBTRUE\fP, and a function key is pressed, the token for
+that function key is returned instead of the raw characters:
+.bP
+The predefined function
+keys are listed in \fB<curses.h>\fP as macros with values outside the range
+of 8-bit characters.
+Their names begin with \fBKEY_\fP.
+.bP
+Other (user-defined) function keys which may be defined
+using \fBdefine_key\fP(3X)
+have no names, but also are expected to have values outside the range of
+8-bit characters.
+.PP
+Thus, a variable
+intended to hold the return value of a function key must be of short size or
+larger.
+.PP
+When a character that could be the beginning of a function key is received
+(which, on modern terminals, means an escape character),
+\fBcurses\fP sets a timer.
+If the remainder of the sequence does not come in within the designated
+time, the character is passed through;
+otherwise, the function key value is returned.
+For this reason, many terminals experience a delay between the time
+a user presses the escape key and the escape is returned to the program.
+.PP
+In \fBncurses\fP, the timer normally expires after
+the value in \fBESCDELAY\fP (see \fBcurs_variables\fP(3X)).
+If \fBnotimeout\fP is \fBTRUE\fP, the timer does not expire;
+it is an infinite (or very large) value.
+Because function keys usually begin with an escape character,
+the terminal may appear to hang in notimeout mode after pressing the escape key
+until another key is pressed.
+.SS Ungetting characters
+.PP
+The \fBungetch\fP routine places \fIch\fP back onto the input queue to be
+returned by the next call to \fBwgetch\fP.
+There is just one input queue for all windows.
+.PP
+.SS Predefined key-codes
+The following special keys are defined in \fB<curses.h>\fP.
+.bP
+Except for the special case \fBKEY_RESIZE\fP,
+it is necessary to enable \fBkeypad\fP for \fBgetch\fP to return these codes.
+.bP
+Not all of these are necessarily supported on any particular terminal.
+.bP
+The naming convention may seem obscure, with some apparent
+misspellings (such as \*(``RSUME\*('' for \*(``resume\*('').
+The names correspond to the long terminfo capability names for the keys,
+and were defined long ago, in the 1980s.

+.RS 3
+.TP 5
+\fBungetch\fP
+returns \fBERR\fP
+if there is no more room in the FIFO.
+.TP
+\fBwgetch\fP
+returns \fBERR\fP
+if the window pointer is null, or
+if its timeout expires without having any data, or
+if the execution was interrupted by a signal (\fBerrno\fP will be set to
+\fBEINTR\fP).
+.RE
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH NOTES
+Use of the escape key by a programmer for a single character function is
+discouraged, as it will cause a delay of up to one second while the
+keypad code looks for a following function-key sequence.
+.PP
+Some keys may be the same as commonly used control
+keys, e.g.,
+\fBKEY_ENTER\fP versus control/M,
+\fBKEY_BACKSPACE\fP versus control/H.
+Some curses implementations may differ according to whether they
+treat these control keys specially (and ignore the terminfo), or
+use the terminfo definitions.
+\fBNcurses\fP uses the terminfo definition.
+If it says that \fBKEY_ENTER\fP is control/M,
+\fBgetch\fP will return \fBKEY_ENTER\fP
+when you press control/M.
+.PP
+Generally, \fBKEY_ENTER\fP denotes the character(s) sent by the \fIEnter\fP
+key on the numeric keypad:
+.bP
+the terminal description lists the most useful keys,
+.bP
+the \fIEnter\fP key on the regular keyboard is already handled by
+the standard ASCII characters for carriage-return and line-feed,
+.bP
+depending on whether \fBnl\fP or \fBnonl\fP was called,
+pressing \*(``Enter\*('' on the regular keyboard
+may return either a carriage-return or line-feed, and finally
+.bP
+\*(``Enter or send\*('' is the standard description for this key.
+.PP
+When using \fBgetch\fP, \fBwgetch\fP, \fBmvgetch\fP, or
+\fBmvwgetch\fP, nocbreak mode (\fBnocbreak\fP) and echo mode
+(\fBecho\fP) should not be used at the same time.
+Depending on the
+state of the tty driver when each character is typed, the program may
+produce undesirable results.
+.PP
+Note that \fBgetch\fP, \fBmvgetch\fP, and \fBmvwgetch\fP may be macros.
+.PP
+Historically, the set of keypad macros was largely defined by the extremely
+function-key-rich keyboard of the AT&T 7300, aka 3B1, aka Safari 4.
+Modern
+personal computers usually have only a small subset of these.
+IBM PC-style
+consoles typically support little more than \fBKEY_UP\fP, \fBKEY_DOWN\fP,
+\fBKEY_LEFT\fP, \fBKEY_RIGHT\fP, \fBKEY_HOME\fP, \fBKEY_END\fP,
+\fBKEY_NPAGE\fP, \fBKEY_PPAGE\fP, and function keys 1 through 12.
+The Ins key
+is usually mapped to \fBKEY_IC\fP.
+.SH PORTABILITY
+The *get* functions are described in the XSI Curses standard, Issue 4.
+They
+read single-byte characters only.
+The standard specifies that they return
+\fBERR\fP on failure, but specifies no error conditions.
+.PP
+The echo behavior of these functions on input of \fBKEY_\fP or backspace
+characters was not specified in the SVr4 documentation.
+This description is
+adopted from the XSI Curses standard.
+.PP
+The behavior of \fBgetch\fP and friends in the presence of handled signals is
+unspecified in the SVr4 and XSI Curses documentation.
+Under historical curses
+implementations, it varied depending on whether the operating system's
+implementation of handled signal receipt interrupts a \fBread\fP(2) call in
+progress or not, and also (in some implementations) depending on whether an
+input timeout or non-blocking mode has been set.
+.PP
+\fBKEY_MOUSE\fP is mentioned in XSI Curses, along with a few related
+terminfo capabilities, but no higher-level functions use the feature.
+The implementation in ncurses is an extension.
+.PP
+\fBKEY_RESIZE\fP is an extension first implemented for ncurses.
+NetBSD curses later added this extension.
+.PP
+Programmers concerned about portability should be prepared for either of two
+cases: (a) signal receipt does not interrupt \fBgetch\fP; (b) signal receipt
+interrupts \fBgetch\fP and causes it to return \fBERR\fP with \fBerrno\fP set to
+\fBEINTR\fP.
+.PP
+The \fBhas_key\fP function is unique to \fBncurses\fP.
+We recommend that
+any code using it be conditionalized on the \fBNCURSES_VERSION\fP feature macro.

+.br
+.SH DESCRIPTION
+The function \fBgetstr\fP is equivalent to a series of calls to \fBgetch\fP,
+until a newline or carriage return is received (the terminating character is
+not included in the returned string).
+.\" X/Open says also until EOf
+.\" X/Open says then an EOS is added to the result
+.\" X/Open doesn't mention n<0
+The resulting value is placed in the
+area pointed to by the character pointer \fIstr\fP,
+followed by a NUL.
+.PP
+The \fBgetnstr\fP function reads
+from the \fIstdscr\fP default window.
+The other functions, such as \fBwgetnstr\fP,
+read from the window given as a parameter.
+.PP
+\fBgetnstr\fP reads at most \fIn\fP characters, thus preventing a possible
+overflow of the input buffer.
+Any attempt to enter more characters (other
+than the terminating newline or carriage return) causes a beep.
+Function
+keys also cause a beep and are ignored.
+.PP
+The user's \fIerase\fP and \fIkill\fP characters are interpreted:
+.bP
+The \fIerase\fP character (e.g., \fB^H\fP) erases the character
+at the end of the buffer, moving the cursor to the left.
+.IP
+If \fIkeypad\fP mode is on for the window,
+\fBKEY_LEFT\fP and \fBKEY_BACKSPACE\fP
+are both considered equivalent to the user's erase character.
+.bP
+The \fIkill\fP character (e.g., \fB^U\fP) erases the entire buffer,
+leaving the cursor at the beginning of the buffer.
+.PP
+Characters input are echoed only if \fBecho\fP is currently on.
+In that case,
+backspace is echoed as deletion of the previous character (typically a left
+motion).
+.SH RETURN VALUE
+All routines return the integer \fBERR\fP upon failure and an \fBOK\fP (SVr4
+specifies only \*(``an integer value other than \fBERR\fP\*('') upon successful
+completion.
+.PP
+X/Open defines no error conditions.
+.PP
+In this implementation,
+these functions return an error
+if the window pointer is null, or
+if its timeout expires without having any data.
+.PP
+This implementation provides an extension as well.
+If a \fBSIGWINCH\fP interrupts the function, it will return \fBKEY_RESIZE\fP
+rather than \fBOK\fP or \fBERR\fP.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH NOTES
+Note that \fBgetstr\fP, \fBmvgetstr\fP, and \fBmvwgetstr\fP may be macros.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+They read single-byte characters only.
+The standard does not define any error conditions.
+This implementation returns \fBERR\fP if the window pointer is null,
+or if the lower-level \fBwgetch\fP(3X) call returns an \fBERR\fP.
+.PP
+SVr3 and early SVr4 curses implementations did not reject function keys;
+the SVr4.0 documentation claimed that \*(``special keys\*(''
+(such as function keys,
+\*(``home\*('' key,
+\*(``clear\*('' key,
+\fIetc\fP.) are \*(``interpreted\*('',
+without giving details.
+It lied.
+In fact, the \*(``character\*('' value appended to the
+string by those implementations was predictable but not useful
+(being, in fact, the low-order eight bits of the key's KEY_ value).
+.PP
+The functions \fBgetnstr\fP, \fBmvgetnstr\fP, and \fBmvwgetnstr\fP were
+present but not documented in SVr4.
+.PP
+X/Open Curses, Issue 5 (2007) stated that these functions
+\*(``read at most \fIn\fP bytes\*(''
+but did not state whether the terminating NUL is counted in that limit.
+X/Open Curses, Issue 7 (2009) changed that to say they
+\*(``read at most \fIn\fP\-1 bytes\*(''
+to allow for the terminating NUL.
+As of 2018, some implementations do, some do not count it:
+.bP
+ncurses 6.1 and PDCurses do not count the NUL in the given limit, while
+.bP
+Solaris SVr4 and NetBSD curses count the NUL as part of the limit.
+.bP
+Solaris xcurses provides both:
+its wide-character \fBwget_nstr\fP reserves a NUL,
+but its \fBwgetnstr\fP does not count the NUL consistently.
+.PP
+In SVr4 curses,
+a negative value of \fIn\fP tells \fBwgetnstr\fP to assume that the
+caller's buffer is large enough to hold the result,
+i.e., to act like \fBwgetstr\fP.
+X/Open Curses does not mention this
+(or anything related to negative or zero values of \fIn\fP),
+however most implementations
+use the feature, with different limits:
+.bP
+Solaris SVr4 curses and PDCurses limit the result to 255 bytes.
+Other Unix systems than Solaris are likely to use the same limit.
+.bP
+Solaris xcurses limits the result to \fBLINE_MAX\fP bytes.
+.bP
+NetBSD 7 assumes no particular limit for the result from \fBwgetstr\fP.
+However, it limits the \fBwgetnstr\fP parameter \fIn\fP to ensure
+that it is greater than zero.
+.IP
+A comment in NetBSD's source code states that this is specified in SUSv2.
+.bP
+ncurses (before 6.2) assumes no particular limit for the result
+from \fBwgetstr\fP, and treats the \fIn\fP parameter of \fBwgetnstr\fP
+like SVr4 curses.
+.bP
+ncurses 6.2 uses \fBLINE_MAX\fP,
+or a larger (system-dependent) value
+which the \fBsysconf\fP function may provide.
+If neither \fBLINE_MAX\fP or \fBsysconf\fP is available,
+ncurses uses the POSIX value for \fBLINE_MAX\fP (a 2048 byte limit).
+In either case, it reserves a byte for the terminating NUL.
+.PP
+Although \fBgetnstr\fP is equivalent to a series of calls to \fBgetch\fP,
+it also makes changes to the curses modes to allow simple editing of
+the input buffer:
+.bP
+\fBgetnstr\fP saves the current value of the \fBnl\fP, \fBecho\fP,
+\fBraw\fP and \fBcbreak\fP modes, and sets
+\fBnl\fP,
+\fBnoecho\fP,
+\fBnoraw\fP, and
+\fBcbreak\fP.
+.IP
+\fBgetnstr\fP handles the echoing of characters,
+rather than relying on the caller to set an appropriate mode.
+.bP
+It also obtains the \fIerase\fP and \fIkill\fP characters
+from \fBerasechar\fP and \fBkillchar\fP, respectively.
+.bP
+On return, \fBgetnstr\fP restores the modes to their previous values.
+.PP
+Other implementations differ in their treatment of special characters:
+.bP
+While they may set the \fIecho\fP mode,
+other implementations do not modify the \fIraw\fP mode,
+They may take the \fIcbreak\fP
+mode set by the caller into account when deciding whether to handle
+echoing within \fBgetnstr\fP or as a side-effect of the \fBgetch\fP calls.
+.bP
+The original ncurses (as \fIpcurses\fP in 1986) set \fBnoraw\fP and \fBcbreak\fP
+when accepting input for \fBgetnstr\fP.
+That may have been done to make function- and cursor-keys work;
+it is not necessary with ncurses.
+.IP
+Since 1995, ncurses has provided signal handlers for INTR and QUIT
+(e.g., \fB^C\fP or \fB^\\\fP).
+With the \fBnoraw\fP and \fBcbreak\fP settings,
+those may catch a signal and stop the program,
+where other implementations allow one to enter those characters in the buffer.
+.bP
+Starting in 2021 (ncurses 6.3), \fBgetnstr\fP sets \fBraw\fP,
+rather than \fBnoraw\fP and \fBcbreak\fP for better compatibility with
+SVr4-curses, e.g., allowing one to enter a \fB^C\fP into the buffer.

+\fBvoid getyx(WINDOW *\fIwin\fB, int \fIy\fB, int \fIx\fB);\fR

+.SH DESCRIPTION
+The \fBgetyx\fP macro places the current cursor position of the given window in
+the two integer variables \fIy\fP and \fIx\fP.
+.PP
+If \fIwin\fP is a subwindow, the \fBgetparyx\fP macro places the beginning
+coordinates of the subwindow relative to the parent window into two integer
+variables \fIy\fP and \fIx\fP.
+Otherwise, \fB\-1\fP is placed into \fIy\fP and \fIx\fP.
+.PP
+Like \fBgetyx\fP, the \fBgetbegyx\fP and \fBgetmaxyx\fP macros store
+the current beginning coordinates and size of the specified window.
+.SH RETURN VALUE
+The return values of these macros are undefined (i.e.,
+they should not be used as the right-hand side of assignment statements).
+.SH NOTES
+All of these interfaces are macros.
+A "\fB&\fP" is not necessary before the variables \fIy\fP and \fIx\fP.
+.SH PORTABILITY
+The
+\fBgetyx\fP,
+\fBgetparyx\fP,
+\fBgetbegyx\fP and
+\fBgetmaxyx\fP
+macros are described in the XSI Curses standard, Issue 4.
+.PP
+This implementation also provides functions
+\fBgetbegx\fP,
+\fBgetbegy\fP,
+\fBgetcurx\fP,
+\fBgetcury\fP,
+\fBgetmaxx\fP,
+\fBgetmaxy\fP,
+\fBgetparx\fP and
+\fBgetpary\fP
+for compatibility with older versions of curses.
+.PP
+Although X/Open Curses does not address this,
+many implementations provide members of the WINDOW structure
+containing values corresponding to these macros.
+For best portability, do not rely on using the data in WINDOW,
+since some implementations make WINDOW opaque (do not allow

+\fBinch\fP,

+\fBchtype mvwinch(WINDOW *\fIwin\fB, int \fIy\fB, int \fIx\fB);\fR
+.br
+.SH DESCRIPTION
+These routines return the character, of type \fBchtype\fP, at the current
+position in the named window.
+If any attributes are set for that position,
+their values are OR'ed into the value returned.
+Constants defined in
+\fB<curses.h>\fP can be used with the \fB&\fP (logical AND) operator to
+extract the character or attributes alone.
+.
+.SS Attributes
+The following bit-masks may be AND-ed with characters returned by \fBwinch\fP.
+.
+.TS
+l l .
+\fBA_CHARTEXT\fP	Bit-mask to extract character
+\fBA_ATTRIBUTES\fP	Bit-mask to extract attributes
+\fBA_COLOR\fP	Bit-mask to extract color-pair field information
+.TE
+.SH RETURN VALUE
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.PP
+The \fBwinch\fP function does not return an error if the window contains
+characters larger than 8-bits (255).
+Only the low-order 8 bits of the character are used by \fBwinch\fP.
+.SH NOTES
+Note that all of these routines may be macros.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+.PP
+Very old systems (before standardization) provide a different function
+with the same name:
+.bP
+The \fBwinch\fP function was part of the original BSD curses library,
+which stored a 7-bit character combined with the \fIstandout\fP attribute.
+.IP
+In BSD curses, \fBwinch\fP returned only the character (as an integer)
+with the \fIstandout\fP attribute removed.
+.bP
+System V curses added support for several video attributes which
+could be combined with characters in the window.
+.IP
+Reflecting this improvement, the function was altered to return the
+character combined with all video attributes in a \fBchtype\fP value.
+.PP
+X/Open Curses does not specify
+the size and layout of attributes, color and character values in
+\fBchtype\fP; it is implementation-dependent.
+This implementation uses 8 bits for character values.
+An application using more bits, e.g., a Unicode value,
+should use the wide-character equivalents to these functions.

+.br
+.SH DESCRIPTION
+.SS initscr
+\fBinitscr\fP is normally the first \fBcurses\fP routine to call when
+initializing a program.
+A few special routines sometimes need to be called before it;
+these are \fBslk_init\fP(3X), \fBfilter\fP, \fBripoffline\fP,
+\fBuse_env\fP.
+For multiple-terminal applications,
+\fBnewterm\fP may be called before \fBinitscr\fP.
+.PP
+The initscr code determines the terminal type and initializes all \fBcurses\fP
+data structures.
+\fBinitscr\fP also causes the first call to \fBrefresh\fP(3X)
+to clear the screen.
+If errors occur, \fBinitscr\fP writes an appropriate error
+message to standard error and exits;
+otherwise, a pointer is returned to \fBstdscr\fP.
+.SS newterm
+.PP
+A program that outputs to more than one terminal should use the \fBnewterm\fP
+routine for each terminal instead of \fBinitscr\fP.
+A program that needs to inspect capabilities,
+so it can continue to run in a line-oriented mode if the
+terminal cannot support a screen-oriented program, would also use
+\fBnewterm\fP.
+The routine \fBnewterm\fP should be called once for each terminal.
+It returns a variable of type \fBSCREEN *\fP which should be saved
+as a reference to that terminal.
+\fBnewterm\fP's arguments are
+.bP
+the \fItype\fP of the terminal to be used in place of \fB$TERM\fP,
+.bP
+a file pointer for output to the terminal, and
+.bP
+another file pointer for input from the terminal
+.PP
+If the \fItype\fP parameter is \fBNULL\fP, \fB$TERM\fP will be used.
+.SS endwin
+.PP
+The program must also call
+\fBendwin\fP for each terminal being used before exiting from \fBcurses\fP.
+If \fBnewterm\fP is called more than once for the same terminal, the first
+terminal referred to must be the last one for which \fBendwin\fP is called.
+.PP
+A program should always call \fBendwin\fP before exiting or escaping from
+\fBcurses\fP mode temporarily.
+This routine
+.bP
+resets colors to correspond with the default color pair 0,
+.bP
+moves the cursor to the lower left-hand corner of the screen,
+.bP
+clears the remainder of the line so that it uses the default colors,
+.bP
+sets the cursor to normal visibility (see \fBcurs_set\fP(3X)),
+.bP
+stops cursor-addressing mode using the \fIexit_ca_mode\fP terminal capability,
+.bP
+restores tty modes (see \fBreset_shell_mode\fP(3X)).
+.PP
+Calling \fBrefresh\fP(3X) or \fBdoupdate\fP(3X) after a
+temporary escape causes the program to resume visual mode.
+.SS isendwin
+.PP
+The \fBisendwin\fP routine returns \fBTRUE\fP if \fBendwin\fP has been
+called without any subsequent calls to \fBwrefresh\fP,
+and \fBFALSE\fP otherwise.
+.SS set_term
+.PP
+The \fBset_term\fP routine is used to switch between different terminals.
+The screen reference \fInew\fP becomes the new current terminal.
+The previous terminal is returned by the routine.
+This is the only routine which manipulates \fBSCREEN\fP pointers;
+all other routines affect only the current terminal.
+.SS delscreen
+.PP
+The \fBdelscreen\fP routine frees storage associated with the
+\fBSCREEN\fP data structure.
+The \fBendwin\fP routine does not do
+this, so \fBdelscreen\fP should be called after \fBendwin\fP if a
+particular \fBSCREEN\fP is no longer needed.
+.SH RETURN VALUE
+\fBendwin\fP returns the integer \fBERR\fP upon failure and \fBOK\fP
+upon successful completion.
+.PP
+Routines that return pointers always return \fBNULL\fP on error.
+.PP
+X/Open defines no error conditions.
+In this implementation
+.bP
+\fBendwin\fP returns an error if the terminal was not initialized.
+.bP
+\fBnewterm\fP
+returns an error if it cannot allocate the data structures for the screen,
+or for the top-level windows within the screen,
+i.e.,
+\fBcurscr\fP, \fBnewscr\fP, or \fBstdscr\fP.
+.bP
+\fBset_term\fP
+returns no error.
+.SH PORTABILITY
+These functions were described in the XSI Curses standard, Issue 4.
+As of 2015, the current document is X/Open Curses, Issue 7.
+.SS Differences
+X/Open specifies that portable applications must not
+call \fBinitscr\fP more than once:
+.bP
+The portable way to use \fBinitscr\fP is once only,
+using \fBrefresh\fP (see curs_refresh(3X))
+to restore the screen after \fBendwin\fP.
+.bP
+This implementation allows using \fBinitscr\fP after \fBendwin\fP.
+.PP
+Old versions of curses, e.g., BSD 4.4, would return a null pointer
+from \fBinitscr\fP when an error is detected, rather than exiting.
+It is safe but redundant to check the return value of \fBinitscr\fP
+in XSI Curses.
+.PP
+Calling \fBendwin\fP does not dispose of the memory allocated in \fBinitscr\fP
+or \fBnewterm\fP.
+Deleting a \fBSCREEN\fP provides a way to do this:
+.bP
+X/Open Curses does not say what happens to \fBWINDOW\fPs when \fBdelscreen\fP
+\*(``frees storage associated with the \fBSCREEN\fP\*(''
+nor does the SVr4 documentation help,
+adding that it should be called after \fBendwin\fP if a \fBSCREEN\fP
+is no longer needed.
+.bP
+However, \fBWINDOW\fPs are implicitly associated with a \fBSCREEN\fP.
+so that it is reasonable to expect \fBdelscreen\fP to deal with these.
+.bP
+SVr4 curses deletes the standard \fBWINDOW\fP structures
+\fBstdscr\fP and \fBcurscr\fP as well as a work area \fBnewscr\fP.
+SVr4 curses ignores other windows.
+.bP
+Since version 4.0 (1996), ncurses has maintained a list of all windows
+for each screen,
+using that information to delete those windows when \fBdelscreen\fP is called.
+.bP
+NetBSD copied this feature of ncurses in 2001.
+PDCurses follows the SVr4 model,
+deleting only the standard \fBWINDOW\fP structures.
+.SS Unset TERM Variable
+.PP
+If the TERM variable is missing or empty, \fBinitscr\fP uses the
+value \*(``unknown\*('',
+which normally corresponds to a terminal entry with the \fIgeneric\fP
+(\fIgn\fP) capability.
+Generic entries are detected by \fBsetupterm\fP
+(see curs_terminfo(3X)) and cannot be used for full-screen operation.
+Other implementations may handle a missing/empty TERM variable differently.
+.SS Signal Handlers
+.PP
+Quoting from X/Open Curses, section 3.1.1:
+.RS 5
+.hy 0
+.PP
+.I Curses implementations may provide for special handling of the
+.I \fBSIGINT\fP,
+.I \fBSIGQUIT\fP and
+.I \fBSIGTSTP\fP signals
+.I if their disposition is \fBSIG_DFL\fP at the time
+\fBinitscr\fI is called \fR...
+.PP
+.I Any special handling for these signals may remain in effect for the
+.I life of the process or until the process changes the disposition of
+.I the signal.
+.PP
+.I None of the Curses functions are required to be safe
+.I with respect to signals \fP...
+.RE
+.hy
+.PP
+This implementation establishes signal handlers during initialization,
+e.g., \fBinitscr\fP or \fBnewterm\fP.
+Applications which must handle these signals should set up the corresponding
+handlers \fIafter\fP initializing the library:
+.TP 5
+.B SIGINT
+The handler \fIattempts\fP to cleanup the screen on exit.
+Although it \fIusually\fP works as expected, there are limitations:
+.RS 5
+.bP
+Walking the \fBSCREEN\fP list is unsafe, since all list management
+is done without any signal blocking.
+.bP
+On systems which have \fBREENTRANT\fP turned on, \fBset_term\fP uses
+functions which could deadlock or misbehave in other ways.
+.bP
+\fBendwin\fP calls other functions, many of which use stdio or
+other library functions which are clearly unsafe.
+.RE
+.TP 5
+.B SIGTERM
+This uses the same handler as \fBSIGINT\fP, with the same limitations.
+It is not mentioned in X/Open Curses, but is more suitable for this
+purpose than \fBSIGQUIT\fP (which is used in debugging).
+.TP 5
+.B SIGTSTP
+This handles the \fIstop\fP signal, used in job control.
+When resuming the process, this implementation discards pending
+input with \fBflushinput\fP (see curs_util(3X)), and repaints the screen
+assuming that it has been completely altered.
+It also updates the saved terminal modes with \fBdef_shell_mode\fP
+(see \fBcurs_kernel\fP(3X)).
+.TP 5
+.B SIGWINCH
+This handles the window-size changes which were ignored in
+the standardization efforts.
+The handler sets a (signal-safe) variable
+which is later tested in \fBwgetch\fP (see curs_getch(3X)).
+If \fBkeypad\fP has been enabled for the corresponding window,
+\fBwgetch\fP returns the key symbol \fBKEY_RESIZE\fP.
+At the same time, \fBwgetch\fP calls \fBresizeterm\fP to adjust the
+standard screen \fBstdscr\fP,
+and update other data such as \fBLINES\fP and \fBCOLS\fP.

+.SH DESCRIPTION
+The \fBncurses\fP library provides several functions which let an application
+change the way input from the terminal is handled.
+Some are global, applying to all windows.
+Others apply only to a specific window.
+Window-specific settings are not automatically applied to new or derived
+windows.
+An application must apply these to each window, if the same behavior
+is needed.
+.\"
+.SS cbreak/nocbreak
+Normally, the tty driver buffers typed characters until a newline or carriage
+return is typed.
+The \fBcbreak\fP routine disables line buffering and
+erase/kill character-processing (interrupt and flow control characters are
+unaffected), making characters typed by the user immediately available to the
+program.
+The \fBnocbreak\fP routine returns the terminal to normal (cooked)
+mode.
+.PP
+Initially the terminal may or may not be in \fBcbreak\fP mode, as the mode is
+inherited; therefore, a program should call \fBcbreak\fP or \fBnocbreak\fP
+explicitly.
+Most interactive programs using \fBcurses\fP set the \fBcbreak\fP
+mode.
+Note that \fBcbreak\fP overrides \fBraw\fP.
+[See \fBcurs_getch\fP(3X) for a
+discussion of how these routines interact with \fBecho\fP and \fBnoecho\fP.]
+.\"
+.SS echo/noecho
+.PP
+The \fBecho\fP and \fBnoecho\fP routines control whether characters typed by
+the user are echoed by \fBgetch\fP(3X) as they are typed.
+Echoing by the tty
+driver is always disabled, but initially \fBgetch\fP is in echo mode, so
+characters typed are echoed.
+Authors of most interactive programs prefer to do
+their own echoing in a controlled area of the screen, or not to echo at all, so
+they disable echoing by calling \fBnoecho\fP.
+[See \fBcurs_getch\fP(3X) for a
+discussion of how these routines interact with \fBcbreak\fP and
+\fBnocbreak\fP.]
+.\"
+.SS halfdelay
+.PP
+The \fBhalfdelay\fP routine is used for half-delay mode, which is similar to
+\fBcbreak\fP mode in that characters typed by the user are immediately
+available to the program.
+However, after blocking for \fItenths\fP tenths of
+seconds, \fBERR\fP is returned if nothing has been typed.
+The value of \fItenths\fP
+must be a number between 1 and 255.
+Use \fBnocbreak\fP to leave half-delay
+mode.
+.\"
+.SS intrflush
+.PP
+If the \fBintrflush\fP option is enabled (\fIbf\fP is \fBTRUE\fP), and an
+interrupt key is pressed on the keyboard (interrupt, break, quit), all output in
+the tty driver queue will be flushed, giving the effect of faster response to
+the interrupt, but causing \fBcurses\fP to have the wrong idea of what is on
+the screen.
+Disabling the option (\fIbf\fP is \fBFALSE\fP) prevents the
+flush.
+The default for the option is inherited from the tty driver settings.
+The window argument is ignored.
+.\"
+.SS keypad
+.PP
+The \fBkeypad\fP option enables the keypad of the user's terminal.
+If
+enabled (\fIbf\fP is \fBTRUE\fP), the user can press a function key
+(such as an arrow key) and \fBwgetch\fP(3X) returns a single value
+representing the function key, as in \fBKEY_LEFT\fP.
+If disabled
+(\fIbf\fP is \fBFALSE\fP), \fBcurses\fP does not treat function keys
+specially and the program has to interpret the escape sequences
+itself.
+If the keypad in the terminal can be turned on (made to
+transmit) and off (made to work locally), turning on this option
+causes the terminal keypad to be turned on when \fBwgetch\fP(3X) is
+called.
+The default value for keypad is \fBFALSE\fP.
+.\"
+.SS meta
+.PP
+Initially, whether the terminal returns 7 or 8 significant bits on
+input depends on the control mode of the tty driver [see \fBtermios\fP(3)].
+To force 8 bits to be returned, invoke \fBmeta\fP(\fIwin\fP,
+\fBTRUE\fP); this is equivalent, under POSIX, to setting the CS8 flag
+on the terminal.
+To force 7 bits to be returned, invoke
+\fBmeta\fP(\fIwin\fP, \fBFALSE\fP); this is equivalent, under POSIX,
+to setting the CS7 flag on the terminal.
+The window argument,
+\fIwin\fP, is always ignored.
+If the terminfo capabilities \fBsmm\fP
+(meta_on) and \fBrmm\fP (meta_off) are defined for the terminal,
+\fBsmm\fP is sent to the terminal when \fBmeta\fP(\fIwin\fP,
+\fBTRUE\fP) is called and \fBrmm\fP is sent when \fBmeta\fP(\fIwin\fP,
+\fBFALSE\fP) is called.
+.\"
+.SS nl/nonl
+.PP
+The \fBnl\fP and \fBnonl\fP routines control whether the underlying display
+device translates the return key into newline on input.
+.\"
+.SS nodelay
+.PP
+The \fBnodelay\fP option causes \fBgetch\fP to be a non-blocking call.
+If no input is ready, \fBgetch\fP returns \fBERR\fP.
+If disabled
+(\fIbf\fP is \fBFALSE\fP), \fBgetch\fP waits until a key is pressed.
+.SS notimeout
+.PP
+When interpreting an escape sequence, \fBwgetch\fP(3X) sets a timer
+while waiting for the next character.
+If \fBnotimeout(\fIwin\fR,
+\fBTRUE\fP) is called, then \fBwgetch\fP does not set a timer.
+The
+purpose of the timeout is to differentiate between sequences received
+from a function key and those typed by a user.
+.\"
+.SS raw/noraw
+.PP
+The \fBraw\fP and \fBnoraw\fP routines place the terminal into or out of raw
+mode.
+Raw mode is similar to \fBcbreak\fP mode, in that characters typed are
+immediately passed through to the user program.
+The differences are that in
+raw mode, the interrupt, quit, suspend, and flow control characters are all
+passed through uninterpreted, instead of generating a signal.
+The behavior of
+the BREAK key depends on other bits in the tty driver that are not set by
+\fBcurses\fP.
+.\"
+.SS qiflush/noqiflush
+.PP
+When the \fBnoqiflush\fP routine is used, normal flush of input and
+output queues associated with the \fBINTR\fP, \fBQUIT\fP and
+\fBSUSP\fP characters will not be done [see \fBtermios\fP(3)].
+When
+\fBqiflush\fP is called, the queues will be flushed when these control
+characters are read.
+You may want to call \fBnoqiflush\fP in a signal
+handler if you want output to continue as though the interrupt
+had not occurred, after the handler exits.
+.\"
+.SS timeout/wtimeout
+.PP
+The \fBtimeout\fP and \fBwtimeout\fP routines set blocking or
+non-blocking read for a given window.
+If \fIdelay\fP is negative,
+blocking read is used (i.e., waits indefinitely for
+input).
+If \fIdelay\fP is zero, then non-blocking read is used
+(i.e., read returns \fBERR\fP if no input is waiting).
+If
+\fIdelay\fP is positive, then read blocks for \fIdelay\fP
+milliseconds, and returns \fBERR\fP if there is still no input.
+Hence, these routines provide the same functionality as \fBnodelay\fP,
+plus the additional capability of being able to block for only
+\fIdelay\fP milliseconds (where \fIdelay\fP is positive).
+.\"
+.SS typeahead
+.PP
+The \fBcurses\fP library does \*(``line-breakout optimization\*(''
+by looking for typeahead periodically while updating the screen.
+If input is found, and it is coming from a tty,
+the current update is postponed until
+\fBrefresh\fP(3X) or \fBdoupdate\fP is called again.
+This allows faster response to commands typed in advance.
+Normally, the input FILE
+pointer passed to \fBnewterm\fP, or \fBstdin\fP in the case that
+\fBinitscr\fP was used, will be used to do this typeahead checking.
+The \fBtypeahead\fP routine specifies that the file descriptor
+\fIfd\fP is to be used to check for typeahead instead.
+If \fIfd\fP is
+\-1, then no typeahead checking is done.
+.\"
+.SH RETURN VALUE
+All routines that return an integer return \fBERR\fP upon failure and \fBOK\fP
+(SVr4 specifies only \*(``an integer value other than \fBERR\fP\*('')
+upon successful completion,
+unless otherwise noted in the preceding routine descriptions.
+.PP
+X/Open does not define any error conditions.
+In this implementation,
+functions with a window parameter will return an error if it is null.
+Any function will also return an error if the terminal was not initialized.
+Also,
+.RS
+.TP 5
+\fBhalfdelay\fP
+returns an error
+if its parameter is outside the range 1..255.
+.RE
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+.PP
+The ncurses library obeys the XPG4 standard and the historical practice of the
+AT&T curses implementations, in that the echo bit is cleared when curses
+initializes the terminal state.
+BSD curses differed from this slightly; it
+left the echo bit on at initialization, but the BSD \fBraw\fP call turned it
+off as a side-effect.
+For best portability, set \fBecho \fPor \fBnoecho\fP explicitly
+just after initialization, even if your program remains in cooked mode.
+.PP
+The XSI Curses standard is ambiguous on the question of whether \fBraw\fP
+should disable the CRLF translations controlled by \fBnl\fP and \fBnonl\fP.
+BSD curses did turn off these translations; AT&T curses (at least as late as
+SVr1) did not.
+We chose to do so, on the theory that a programmer requesting
+raw input wants a clean (ideally 8-bit clean) connection that the operating
+system will not alter.
+.PP
+When \fBkeypad\fP is first enabled,
+ncurses loads the key-definitions for the current terminal description.
+If the terminal description includes extended string capabilities,
+e.g., from using the \fB\-x\fP option of \fB@TIC@\fP,
+then ncurses also defines keys for the capabilities whose names
+begin with \*(``k\*(''.
+The corresponding keycodes are generated and (depending on previous
+loads of terminal descriptions) may differ from one execution of a
+program to the next.
+The generated keycodes are recognized by the \fBkeyname\fP function
+(which will then return a name beginning with \*(``k\*('' denoting the
+terminfo capability name rather than \*(``K\*('', used for curses key-names).
+On the other hand, an application can use \fBdefine_key\fP to establish
+a specific keycode for a given string.
+This makes it possible for an application to check for an extended
+capability's presence with \fBtigetstr\fP,
+and reassign the keycode to match its own needs.
+.PP
+Low-level applications can use \fBtigetstr\fP to obtain the definition
+of any particular string capability.
+Higher-level applications which use the curses \fBwgetch\fP
+and similar functions to return keycodes rely upon the order in which
+the strings are loaded.
+If more than one key definition has the same string value,
+then \fBwgetch\fP can return only one keycode.
+Most curses implementations (including ncurses)
+load key definitions in the order
+defined by the array of string capability names.
+The last key to be loaded determines the keycode which will be returned.
+In ncurses, you may also have extended capabilities interpreted as
+key definitions.
+These are loaded after the predefined keys,
+and if a capability's value is the same as a previously-loaded
+key definition,
+the later definition is the one used.
+.SH NOTES
+Note that
+\fBecho\fP,
+\fBnoecho\fP,
+\fBhalfdelay\fP,
+\fBintrflush\fP,
+\fBmeta\fP,
+\fBnl\fP,
+\fBnonl\fP,
+\fBnodelay\fP,
+\fBnotimeout\fP,
+\fBnoqiflush\fP,
+\fBqiflush\fP,
+\fBtimeout\fP, and
+\fBwtimeout\fP may be macros.
+.PP
+The \fBnoraw\fP and \fBnocbreak\fP calls follow historical practice in that
+they attempt to restore to normal (\*(``cooked\*('') mode
+from raw and cbreak modes respectively.
+Mixing raw/noraw and cbreak/nocbreak calls leads to tty driver
+control states that are hard to predict or understand; it is not recommended.

+These routines insert a \fBwchar_t\fP character string
+(as many characters as will fit on the line)
+before the character under the cursor.
+All characters to the right of the cursor are shifted right,
+with the possibility of the rightmost characters on the line being lost.
+No wrapping is performed.
+The cursor position does not change
+(after moving to \fIy\fP, \fIx\fP, if specified).
+The four routines with \fIn\fP as the last argument
+insert a leading substring of at most \fIn\fP \fBwchar_t\fP characters.
+If \fIn\fP is less than 1, the entire string is inserted.
+.PP
+If a character in \fIwstr\fP is a tab, newline, carriage return or
+backspace, the cursor is moved appropriately within the window.
+A newline also does a \fBclrtoeol\fP before moving.
+Tabs are considered to be at every eighth column.
+If a character in \fIwstr\fP is another control character,
+it is drawn in the \fB^\fIX\fR notation.
+Calling \fBwin_wch\fP after adding a control character
+(and moving to it, if necessary)
+does not return the control character,
+but instead returns a character in the ^-representation
+of the control character.
+.SH NOTES
+Note that all but wins_nwstr may be macros.
+.PP
+If the first character in the string is a nonspacing character, these
+functions will fail.

+Upon successful completion, these functions return \fBOK\fP.
+Otherwise, they return \fBERR\fP.

+.SH DESCRIPTION
+These routines insert a character string
+(as many characters as will fit on the line)
+before the character under the cursor.
+All characters to the right of the cursor are shifted right
+with the possibility of the rightmost characters on the line being lost.
+The cursor position does not change
+(after moving to \fIy\fP, \fIx\fP, if specified).
+The functions with \fIn\fP as the last argument
+insert a leading substring of at most \fIn\fP characters.
+If \fIn\fP<=0, then the entire string is inserted.
+.PP
+Special characters are handled as in \fBaddch\fP.
+.SH RETURN VALUE
+All routines that return an integer return \fBERR\fP upon failure and \fBOK\fP
+(SVr4 specifies only "an integer value other than \fBERR\fP")
+upon successful completion,
+unless otherwise noted in the preceding routine descriptions.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+if the window parameter is null or the str parameter is null,
+an error is returned.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH NOTES
+Note that all but \fBwinsnstr\fP may be macros.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4, which adds
+const qualifiers to the arguments.
+.LP
+The Single Unix Specification, Version 2 states that
+\fBinsnstr\fP and \fBwinsnstr\fP perform wrapping.
+This is probably an error, since it makes this group of functions inconsistent.
+Also, no implementation of curses documents this inconsistency.

+.SH DESCRIPTION
+The following routines give low-level access
+to various \fBcurses\fP capabilities.
+These routines typically are used inside library routines.
+.SS def_prog_mode, def_shell_mode
+.PP
+The \fBdef_prog_mode\fP and \fBdef_shell_mode\fP routines save the
+current terminal modes as the \*(``program\*('' (in \fBcurses\fP) or \*(``shell\*(''
+(not in \fBcurses\fP) state for use by the \fBreset_prog_mode\fP and
+\fBreset_shell_mode\fP routines.
+This is done automatically by \fBinitscr\fP.
+There is one such save area for each screen context
+allocated by \fBnewterm\fP.
+.SS reset_prog_mode, reset_shell_mode
+.PP
+The \fBreset_prog_mode\fP and \fBreset_shell_mode\fP routines restore
+the terminal to \*(``program\*('' (in \fBcurses\fP) or \*(``shell\*('' (out of
+\fBcurses\fP) state.
+These are done automatically by \fBendwin\fP(3X) and,
+after an \fBendwin\fP, by \fBdoupdate\fP,
+so they normally are not called.
+.SS resetty, savetty
+.PP
+The \fBresetty\fP and \fBsavetty\fP routines save and restore the
+state of the terminal modes.
+\fBsavetty\fP saves the current state in
+a buffer and \fBresetty\fP restores the state to what it was at the
+last call to \fBsavetty\fP.
+.SS getsyx
+.PP
+The \fBgetsyx\fP routine returns the current coordinates
+of the \fIvirtual screen\fP cursor in \fIy\fP and \fIx\fP.
+If \fBleaveok\fP is currently \fBTRUE\fP, then
+\fB\-1\fP,\fB\-1\fP is returned.
+If lines have been removed from the top of the
+screen, using \fBripoffline\fP, \fIy\fP and \fIx\fP include these lines;
+therefore, \fIy\fP and \fIx\fP should be used only as arguments for
+\fBsetsyx\fP.
+.PP
+Few applications will use this feature,
+most use \fBgetyx\fP instead.
+.SS setsyx
+.PP
+The \fBsetsyx\fP routine sets
+the \fIvirtual screen\fP cursor to \fIy\fP, \fIx\fP.
+If \fIy\fP and \fIx\fP are both \fB\-1\fP, then
+\fBleaveok\fP is set.
+The two routines \fBgetsyx\fP and \fBsetsyx\fP
+are designed to be used by a library routine, which manipulates
+\fBcurses\fP windows but does not want to change the current position
+of the program's cursor.
+The library routine would call \fBgetsyx\fP
+at the beginning, do its manipulation of its own windows, do a
+\fBwnoutrefresh\fP on its windows, call \fBsetsyx\fP, and then call
+\fBdoupdate\fP.
+.PP
+Few applications will use this feature,
+most use \fBwmove\fP instead.
+.SS ripoffline
+.PP
+The \fBripoffline\fP routine provides access to the same facility that
+\fBslk_init\fP [see \fBcurs_slk\fP(3X)] uses to reduce the size of the
+screen.
+\fBripoffline\fP must be called before \fBinitscr\fP or
+\fBnewterm\fP is called, to prepare these initial actions:
+.bP
+If \fIline\fP is positive, a line is removed from the top of \fBstdscr\fP.
+.bP
+if \fIline\fP is negative, a line is removed from the bottom.
+.PP
+When the resulting initialization is done inside \fBinitscr\fP, the
+routine \fBinit\fP (supplied by the user) is called with two
+arguments:
+.bP
+a window pointer to the one-line window that has been
+allocated and
+.bP
+an integer with the number of columns in the window.
+.PP
+Inside this initialization routine, the integer variables \fBLINES\fP
+and \fBCOLS\fP (defined in \fB<curses.h>\fP) are not guaranteed to be
+accurate and \fBwrefresh\fP or \fBdoupdate\fP must not be called.
+It is allowable to call \fBwnoutrefresh\fP during the initialization routine.
+.PP
+\fBripoffline\fP can be called up to five times before calling \fBinitscr\fP or
+\fBnewterm\fP.
+.SS curs_set
+.PP
+The \fBcurs_set\fP routine sets the cursor state to invisible,
+normal, or very visible for \fBvisibility\fP equal to \fB0\fP,
+\fB1\fP, or \fB2\fP respectively.
+If the terminal supports the \fIvisibility\fP requested,
+the previous \fIcursor\fP state is returned;
+otherwise, \fBERR\fP is returned.
+.SS napms
+.PP
+The \fBnapms\fP routine is used to sleep for \fIms\fP milliseconds.
+.SH RETURN VALUE
+Except for \fBcurs_set\fP, these routines always return \fBOK\fP.
+.PP
+\fBcurs_set\fP
+returns the previous cursor state, or \fBERR\fP if the
+requested \fIvisibility\fP is not supported.
+.PP
+X/Open defines no error conditions.
+In this implementation
+.TP 5
+.na
+.hy 0
+\fBdef_prog_mode\fP, \fBdef_shell_mode\fP, \fBreset_prog_mode\fP, \fBreset_shell_mode\fP
+.hy
+.ad
+return an error
+if the terminal was not initialized, or
+if the I/O call to obtain the terminal settings fails.
+.TP 5
+\fBripoffline\fP
+returns an error if the maximum number of ripped-off lines
+exceeds the maximum (NRIPS = 5).
+.SH NOTES
+Note that \fBgetsyx\fP is a macro, so \fB&\fP is not necessary before
+the variables \fIy\fP and \fIx\fP.
+.PP
+Older SVr4 man pages warn that the return value
+of \fBcurs_set\fP \*(``is currently incorrect\*(''.
+This implementation gets it right, but it may be unwise to count
+on the correctness of the return value anywhere else.
+.PP
+Both ncurses and SVr4 will call \fBcurs_set\fP in \fBendwin\fP
+if \fBcurs_set\fP
+has been called to make the cursor other than normal, i.e., either
+invisible or very visible.
+There is no way for ncurses to determine the initial cursor state to
+restore that.
+.SH PORTABILITY
+The \fIvirtual screen\fP functions \fBsetsyx\fP and \fBgetsyx\fP
+are not described in the XSI Curses standard, Issue 4.
+All other functions are as described in XSI Curses.
+.PP
+The SVr4 documentation describes \fBsetsyx\fP and \fBgetsyx\fP
+as having return type int.
+This is misleading, as they are macros with no documented semantics
+for the return value.

+.SH NAME
+curs_legacy \- get \fBcurses\fP cursor and window coordinates, attributes
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint getattrs(const WINDOW *\fIwin\fB);\fR
+.sp
+\fBint getbegx(const WINDOW *\fIwin\fB);\fR
+.br
+\fBint getbegy(const WINDOW *\fIwin\fB);\fR
+.sp
+\fBint getcurx(const WINDOW *\fIwin\fB);\fR
+.br
+\fBint getcury(const WINDOW *\fIwin\fB);\fR
+.sp
+\fBint getmaxx(const WINDOW *\fIwin\fB);\fR
+.br
+\fBint getmaxy(const WINDOW *\fIwin\fB);\fR
+.sp
+\fBint getparx(const WINDOW *\fIwin\fB);\fR
+.br
+\fBint getpary(const WINDOW *\fIwin\fB);\fR
+.br
+.SH DESCRIPTION
+These legacy functions are simpler to use than the X/Open Curses functions:
+.bP
+The \fBgetattrs\fP function returns the same attribute data as \fBwattr_get\fP.
+.IP
+However, \fBgetattrs\fP returns an integer (actually a \fBchtype\fP),
+while \fBwattr_get\fP returns the current color pair in a separate parameter.
+In the wide-character library configuration,
+color pairs may not fit into a \fBchtype\fP,
+so \fBwattr_get\fP is the only way to obtain the color information.
+.IP
+Because \fBgetattrs\fP returns the attributes in a single parameter,
+it would not be possible for an application to distinguish that from
+\fBERR\fP (a \fI-1\fP).
+If the window parameter is null, \fBgetattrs\fP returns \fBA_NORMAL\fP (zero).
+.bP
+The \fBgetbegy\fP and \fBgetbegx\fP functions return the same
+data as \fBgetbegyx\fP.
+.bP
+The \fBgetcury\fP and \fBgetcurx\fP functions return the same
+data as \fBgetyx\fP.
+.bP
+The \fBgetmaxy\fP and \fBgetmaxx\fP functions return the same
+data as \fBgetmaxyx\fP.
+.bP
+The \fBgetpary\fP and \fBgetparx\fP functions return the same
+data as \fBgetparyx\fP.
+.SH RETURN VALUE
+Except as noted,
+these functions return an integer,
+or \fBERR\fP if the window parameter is null.
+.SH NOTES
+All of these interfaces are provided as macros and functions.
+The macros are suppressed (and only the functions provided)
+when \fBNCURSES_OPAQUE\fP is defined.
+The standard forms such as \fBgetyx\fP must be implemented as macros,
+and (in this implementation) are defined in terms of the functions
+described here,
+to avoid reliance on internal details of the WINDOW structure.
+.SH PORTABILITY
+These functions were supported on Version 7, BSD or System V implementations.
+None of those implementations checked the window parameter.
+.PP
+The \fBgetattrs\fP function and macro are defined to return a (signed) integer
+for compatibility with those implementations
+although an unsigned type would have been more appropriate.

+\fBvoid _nc_free_and_exit(int \fIcode\fB);\fR
+.br
+\fBvoid _nc_free_tinfo(int \fIcode\fB);\fR
+.SH DESCRIPTION
+These functions are used to simplify analysis of memory leaks in the ncurses
+library.
+.PP
+Any implementation of curses must not free the memory associated with
+a screen, since (even after calling \fBendwin\fP(3X)), it must be available
+for use in the next call to \fBrefresh\fP(3X).
+There are also chunks of memory held for performance reasons.
+That makes it hard to analyze curses applications for memory leaks.
+When using the specially configured debugging version of the ncurses library,
+applications can call functions which free those chunks of memory,
+simplifying the process of memory-leak checking.
+.PP
+Some of the functions are named with a \*(``_nc_\*('' prefix
+because they are not intended for use in the non-debugging library:
+.TP 5
+\fB_nc_freeall\fP
+This frees (almost) all of the memory allocated by ncurses.
+.TP 5
+\fB_nc_free_and_exit\fP
+This frees the memory allocated by ncurses (like \fB_nc_freeall\fP),
+and exits the program.
+It is preferred over \fB_nc_freeall\fP since some of that memory
+may be required to keep the application running.
+Simply exiting (with the given exit-code) is safer.
+.TP 5
+\fB_nc_free_tinfo\fP
+Use this function if only the low-level terminfo functions (and
+corresponding library) are used.
+Like \fB_nc_free_and_exit\fP, it exits the program after freeing memory.
+.PP
+The functions prefixed \*(``_nc\*('' are normally not available;
+they must be configured into the library
+at build time using the \fB\-\-disable-leaks\fP option.
+That compiles-in code that frees memory that normally would not be freed.
+.PP
+The \fBexit_curses\fP and \fBexit_terminfo\fP functions
+call \fB_nc_free_and_exit\fP and \fB_nc_free_tinfo\fP if
+the library is configured to support memory-leak checking.
+If the library is not configured to support memory-leak checking,
+they simply call \fBexit\fP.
+.SH RETURN VALUE
+These functions do not return a value.
+.SH PORTABILITY
+These functions are not part of X/Open Curses;
+nor do other implementations of curses provide a similar feature.
+.PP
+In any implementation of X/Open Curses, an application can free part
+of the memory allocated by curses:
+.bP
+The portable part of \fBexit_curses\fP can be freed using \fBdelscreen\fP,
+passing the \fBSCREEN*\fP pointer returned by \fBnewterm\fP.
+.IP
+In some implementations, there is a global variable \fBsp\fP
+which could be used, e.g., if the screen were only initialized
+using \fBinitscr\fP.
+.bP
+The portable part of \fBexit_terminfo\fP can be freed using \fBdel_curterm\fP.
+.IP
+In this case, there is a global variable \fBcur_term\fP which can be
+used as parameter.

+These functions provide an interface to mouse events from
+\fBncurses\fP(3X).
+Mouse events are represented by \fBKEY_MOUSE\fP
+pseudo-key values in the \fBwgetch\fP(3X) input stream.
+.SS mousemask
+.PP
+To make mouse events visible, use the \fBmousemask\fP function.
+This sets the mouse events to be reported.
+By default, no mouse events are reported.
+.bP
+The function returns an updated copy of \fInewmask\fP
+to indicate which of the specified mouse events can be reported.
+.IP
+If the screen has not been initialized,
+or if the terminal does not support mouse-events,
+this function returns 0.
+.bP
+If \fIoldmask\fP is non-NULL,
+this function fills the indicated location with the previous value of the
+current screen's mouse event mask.
+.PP
+As a side effect, setting a zero mousemask may turn off the mouse pointer;
+setting a nonzero mask may turn it on.
+Whether this happens is device-dependent.

+.SS getmouse
+.PP
+Once a class of mouse events has been made visible in a window,
+calling the \fBwgetch\fP function on that window may return
+\fBKEY_MOUSE\fP as an indicator that a mouse event has been queued.
+To read the event data and pop the event off the queue, call
+\fBgetmouse\fP.
+This function will return \fBOK\fP if a mouse event
+is actually visible in the given window, \fBERR\fP otherwise.
+When \fBgetmouse\fP returns \fBOK\fP, the data deposited as y and
+x in the event structure coordinates will be screen-relative character-cell
+coordinates.
+The returned state mask will have exactly one bit set to
+indicate the event type.
+The corresponding data in the queue is marked invalid.
+A subsequent call to \fBgetmouse\fP will retrieve the next older
+item from the queue.
+.SS ungetmouse
+.PP
+The \fBungetmouse\fP function behaves analogously to \fBungetch\fP.
+It pushes
+a \fBKEY_MOUSE\fP event onto the input queue, and associates with that event
+the given state data and screen-relative character-cell coordinates.
+.SS wenclose
+.PP
+The \fBwenclose\fP function tests whether a given pair of screen-relative
+character-cell coordinates is enclosed by a given window, returning \fBTRUE\fP
+if it is and \fBFALSE\fP otherwise.
+It is useful for determining what subset of
+the screen windows enclose the location of a mouse event.
+.SS wmouse_trafo
+.PP
+The \fBwmouse_trafo\fP function transforms a given pair of coordinates
+from stdscr-relative coordinates
+to coordinates relative to the given window or vice versa.
+The resulting stdscr-relative coordinates are not always identical
+to window-relative coordinates due to the mechanism to reserve lines on top
+or bottom of the screen for other purposes
+(see the \fBripoffline\fP and \fBslk_init\fP(3X) calls, for example).
+.bP
+If the parameter \fIto_screen\fP is \fBTRUE\fP, the pointers
+\fIpY, pX\fP must reference the coordinates of a location
+inside the window \fIwin\fP.
+They are converted to window-relative coordinates and returned
+through the pointers.
+If the conversion was successful, the function returns \fBTRUE\fP.
+.bP
+If one of the parameters was NULL or the location is
+not inside the window, \fBFALSE\fP is returned.
+.bP
+If \fIto_screen\fP is
+\fBFALSE\fP, the pointers \fIpY, pX\fP must reference window-relative
+coordinates.
+They are converted to stdscr-relative coordinates if the
+window \fIwin\fP encloses this point.
+In this case the function returns \fBTRUE\fP.
+.bP
+If one of the parameters is NULL or the point is not inside the
+window, \fBFALSE\fP is returned.
+The referenced coordinates
+are only replaced by the converted coordinates if the transformation was
+successful.
+.SS mouse_trafo
+.PP
+The \fBmouse_trafo\fP function performs the same translation
+as \fBwmouse_trafo\fP,
+using stdscr for \fIwin\fP.
+.SS mouseinterval
+.PP
+The \fBmouseinterval\fP function sets the maximum time (in thousands of a
+second) that can elapse between press and release events for them to
+be recognized as a click.
+Use \fBmouseinterval(0)\fP to disable click resolution.
+This function returns the previous interval value.
+Use \fBmouseinterval(\-1)\fP to obtain the interval without altering it.
+The default is one sixth of a second.
+.SS has_mouse
+.PP
+The \fBhas_mouse\fP function returns \fBTRUE\fP if the mouse driver has been
+successfully initialized.
+.PP
+Note that mouse events will be ignored when input is in cooked mode, and will
+cause an error beep when cooked mode is being simulated in a window by a
+function such as \fBgetstr\fP that expects a linefeed for input-loop
+termination.
+.SH RETURN VALUE
+\fBgetmouse\fP and \fBungetmouse\fP
+return the integer \fBERR\fP upon failure or \fBOK\fP
+upon successful completion:
+.RS 3
+.TP 5
+\fBgetmouse\fP
+returns an error.
+.bP
+If no mouse driver was initialized, or
+if the mask parameter is zero,
+.bP
+It returns an error if a mouse event was detected which did not match the
+current \fImousemask\fP.
+.bP
+It also returns an error if no more events remain in the queue.
+.TP 5
+\fBungetmouse\fP
+returns an error if the FIFO is full.
+.RE
+.PP
+\fBmousemask\fP
+returns the mask of reportable events.
+.PP
+\fBmouseinterval\fP
+returns the previous interval value, unless
+the terminal was not initialized.
+In that case, it returns the maximum interval value (166).
+.PP
+\fBwenclose\fP and \fBwmouse_trafo\fP
+are boolean functions returning \fBTRUE\fP or \fBFALSE\fP depending
+on their test result.
+.SH PORTABILITY
+These calls were designed for \fBncurses\fP(3X), and are not found in SVr4
+curses, 4.4BSD curses, or any other previous version of curses.
+.PP
+SVr4 curses had support for the mouse in a variant of \fBxterm\fP(1).
+It is mentioned in a few places, but with no supporting documentation:
+.bP
+the \*(``libcurses\*('' manual page lists functions for this feature
+which are prototyped in \fBcurses.h\fP:
+.NS
+extern int mouse_set(long int);
+extern int mouse_on(long int);
+extern int mouse_off(long int);
+extern int request_mouse_pos(void);
+extern int map_button(unsigned long);
+extern void wmouse_position(WINDOW *, int *, int *);
+extern unsigned long getmouse(void), getbmap(void);
+.NE
+.bP
+the \*(``terminfo\*('' manual page lists capabilities for the feature
+.NS
+buttons           btns    BT       Number of buttons on the mouse
+get_mouse         getm    Gm       Curses should get button events
+key_mouse         kmous   Km       0631, Mouse event has occurred
+mouse_info        minfo   Mi       Mouse status information
+req_mouse_pos     reqmp   RQ       Request mouse position report
+.NE
+.bP
+the interface made assumptions (as does ncurses) about the escape sequences
+sent to and received from the terminal.
+.IP
+For instance
+the SVr4 curses library used the \fBget_mouse\fP capability to tell the
+terminal which mouse button events it should send,
+passing the mouse-button bit-mask to the terminal.
+Also, it could ask the terminal
+where the mouse was using the \fBreq_mouse_pos\fP capability.
+.IP
+Those features required a terminal which had been modified to work with curses.
+They were not part of the X Consortium's xterm.
+.PP
+When developing the xterm mouse support for ncurses in September 1995,
+Eric Raymond was uninterested in using the same interface due to its
+lack of documentation.
+Later, in 1998, Mark Hesseling provided support in
+PDCurses 2.3 using the SVr4 interface.
+PDCurses, however, does not use video terminals,
+making it unnecessary to be concerned about compatibility with the
+escape sequences.
+.PP
+The feature macro \fBNCURSES_MOUSE_VERSION\fP is provided so the preprocessor
+can be used to test whether these features are present.
+If the interface is changed, the value of \fBNCURSES_MOUSE_VERSION\fP will be
+incremented.
+These values for \fBNCURSES_MOUSE_VERSION\fP may be
+specified when configuring ncurses:
+.RS 3
+.TP 3
+1
+has definitions for reserved events.
+The mask uses 28 bits.
+.TP 3
+2
+adds definitions for button 5,
+removes the definitions for reserved events.
+The mask uses 29 bits.
+.RE
+.PP
+The order of the \fBMEVENT\fP structure members is not guaranteed.
+Additional fields may be added to the structure in the future.
+.PP
+Under \fBncurses\fP(3X), these calls are implemented using either
+xterm's built-in mouse-tracking API or
+platform-specific drivers including
+.RS 3
+.bP
+Alessandro Rubini's gpm server
+.bP
+FreeBSD sysmouse
+.bP
+OS/2 EMX
+.RE
+.PP
+If you are using an unsupported configuration,
+mouse events will not be visible to
+\fBncurses\fP(3X) (and the \fBmousemask\fP function will always
+return \fB0\fP).
+.PP
+If the terminfo entry contains a \fBXM\fP string,
+this is used in the xterm mouse driver to control the
+way the terminal is initialized for mouse operation.
+The default, if \fBXM\fP is not found,
+corresponds to private mode 1000 of xterm:
+.PP
+.RS 3
+\\E[?1000%?%p1%{1}%=%th%el%;
+.RE
+.PP
+The mouse driver also recognizes a newer xterm private mode 1006, e.g.,
+.PP
+.RS 3
+\\E[?1006;1000%?%p1%{1}%=%th%el%;
+.RE
+.PP
+The \fIz\fP member in the event structure is not presently used.
+It is intended
+for use with touch screens (which may be pressure-sensitive) or with
+3D-mice/trackballs/power gloves.
+.PP
+The \fBALL_MOUSE_EVENTS\fP class does not include \fBREPORT_MOUSE_POSITION\fP.
+They are distinct.
+For example, in xterm,
+wheel/scrolling mice send position reports as a sequence of
+presses of buttons 4 or 5 without matching button-releases.
+.SH BUGS
+Mouse events under xterm will not in fact be ignored during cooked mode,
+if they have been enabled by \fBmousemask\fP.
+Instead, the xterm mouse
+report sequence will appear in the string read.
+.PP
+Mouse events under xterm will not be detected correctly in a window with
+its keypad bit off, since they are interpreted as a variety of function key.
+Your terminfo description should have \fBkmous\fP set to \*(``\\E[M\*(''
+(the beginning of the response from xterm for mouse clicks).
+Other values for \fBkmous\fP are permitted,
+but under the same assumption,
+i.e., it is the beginning of the response.
+.PP
+Because there are no standard terminal responses that would serve to identify
+terminals which support the xterm mouse protocol, \fBncurses\fP assumes that
+if \fBkmous\fP is defined in the terminal description,
+or if the terminal description's primary name or aliases
+contain the string \*(``xterm\*('',
+then the terminal may send mouse events.
+The \fBkmous\fP capability is checked first,
+allowing the use of newer xterm mouse protocols
+such as xterm's private mode 1006.

+.br
+.SH DESCRIPTION
+.PP
+These routines set options that change the style of output within
+\fBcurses\fP.
+All options are initially \fBFALSE\fP, unless otherwise stated.
+It is not necessary to turn these options off before calling \fBendwin\fP(3X).
+.SS clearok
+.PP
+If \fBclearok\fP is called with \fBTRUE\fP as argument, the next
+call to \fBwrefresh\fP with this window will clear the screen completely and
+redraw the entire screen from scratch.
+This is useful when the contents of the
+screen are uncertain, or in some cases for a more pleasing visual effect.
+If
+the \fIwin\fP argument to \fBclearok\fP is the global variable \fBcurscr\fP,
+the next call to \fBwrefresh\fP with any window causes the screen to be cleared
+and repainted from scratch.
+.SS idlok
+.PP
+If \fBidlok\fP is called with \fBTRUE\fP as second argument, \fBcurses\fP
+considers using the hardware insert/delete line feature of terminals so
+equipped.
+Calling \fBidlok\fP with \fBFALSE\fP as second argument disables use
+of line insertion and deletion.
+This option should be enabled only if the
+application needs insert/delete line, for example, for a screen editor.
+It is
+disabled by default because insert/delete line tends to be visually annoying
+when used in applications where it is not really needed.
+If insert/delete line
+cannot be used, \fBcurses\fP redraws the changed portions of all lines.
+.SS idcok
+.PP
+If \fBidcok\fP is called with \fBFALSE\fP as second argument, \fBcurses\fP
+no longer considers using the hardware insert/delete character feature of
+terminals so equipped.
+Use of character insert/delete is enabled by default.
+Calling \fBidcok\fP with \fBTRUE\fP as second argument re-enables use
+of character insertion and deletion.
+.SS immedok
+.PP
+If \fBimmedok\fP is called with \fBTRUE as argument\fP, any change
+in the window image, such as the ones caused by \fBwaddch, wclrtobot, wscrl\fP,
+etc., automatically cause a call to \fBwrefresh\fP.
+However, it may
+degrade performance considerably, due to repeated calls to \fBwrefresh\fP.
+It is disabled by default.
+.SS leaveok
+.PP
+Normally, the hardware cursor is left at the location of the window cursor
+being refreshed.
+The \fBleaveok\fP option allows the cursor to be left
+wherever the update happens to leave it.
+It is useful for applications where
+the cursor is not used, since it reduces the need for cursor motions.
+.SS scrollok
+.PP
+The \fBscrollok\fP option controls what happens when the cursor of a window is
+moved off the edge of the window or scrolling region, either as a result of a
+newline action on the bottom line, or typing the last character of the last
+line.
+If disabled, (\fIbf\fP is \fBFALSE\fP), the cursor is left on the bottom
+line.
+If enabled, (\fIbf\fP is \fBTRUE\fP), the window is scrolled up one line
+(Note that to get the physical scrolling effect on the terminal, it is
+also necessary to call \fBidlok\fP).
+.SS  setscrreg/wsetscrreg
+.PP
+The \fBsetscrreg\fP and \fBwsetscrreg\fP routines allow the application
+programmer to set a software scrolling region in a window.
+The \fItop\fP and
+\fIbot\fP parameters
+are the line numbers of the top and bottom margin of the scrolling
+region.
+(Line 0 is the top line of the window.)  If this option and
+\fBscrollok\fP are enabled, an attempt to move off the bottom margin line
+causes all lines in the scrolling region to scroll one line in the direction
+of the first line.
+Only the text of the window is scrolled.
+(Note that this
+has nothing to do with the use of a physical scrolling region capability in the
+terminal, like that in the VT100.
+If \fBidlok\fP is enabled and the terminal
+has either a scrolling region or insert/delete line capability, they will
+probably be used by the output routines.)
+.SH RETURN VALUE
+The functions \fBsetscrreg\fP and \fBwsetscrreg\fP return \fBOK\fP upon success
+and \fBERR\fP upon failure.
+All other routines that return an integer always
+return \fBOK\fP.
+.PP
+X/Open Curses does not define any error conditions.
+.PP
+In this implementation,
+.bP
+those functions that have a window pointer
+will return an error if the window pointer is null
+.bP
+\fBwsetscrreg\fP
+returns an error if the scrolling region limits extend outside the window.
+.RE
+.PP
+X/Open does not define any error conditions.
+This implementation returns an error
+if the window pointer is null.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4.
+.PP
+From the outset, ncurses used \fBnl\fP/\fBnonl\fP to control the conversion
+of newlines to carriage return/line-feed on output as well as input.
+XSI Curses documents only the use of these functions for input.
+This difference arose from converting the \fIpcurses\fP source
+(which used \fBioctl\fP calls with the \fBsgttyb\fP structure)
+to termios (i.e., the POSIX terminal interface).
+In the former, both input and output were controlled via a single
+option \fBCRMOD\fP,
+while the latter separates these features.
+Because that conversion interferes with output optimization,
+\fBnl\fP/\fBnonl\fP were amended after ncurses 6.2
+to eliminate their effect on output.
+.PP
+Some historic curses implementations had, as an undocumented feature, the
+ability to do the equivalent of \fBclearok(..., 1)\fP by saying
+\fBtouchwin(stdscr)\fP or \fBclear(stdscr)\fP.
+This will not work under ncurses.
+.PP
+Earlier System V curses implementations specified that with \fBscrollok\fP
+enabled, any window modification triggering a scroll also forced a physical
+refresh.
+XSI Curses does not require this, and \fBncurses\fP avoids doing
+it to perform better vertical-motion optimization at \fBwrefresh\fP
+time.
+.PP
+The XSI Curses standard does not mention that the cursor should be
+made invisible as a side-effect of \fBleaveok\fP.
+SVr4 curses documentation does this, but the code does not.
+Use \fBcurs_set\fP to make the cursor invisible.
+.SH NOTES
+Note that
+\fBclearok\fP,
+\fBleaveok\fP,
+\fBscrollok\fP,
+\fBidcok\fP, and
+\fBsetscrreg\fP may be macros.
+.PP
+The \fBimmedok\fP routine is useful for windows that are used as terminal
+emulators.

+.SS overlay, overwrite
+The \fBoverlay\fP and \fBoverwrite\fP routines overlay \fIsrcwin\fP on

+\fIscrwin\fP and \fIdstwin\fP are not required

+The difference is that \fBoverlay\fP is non-destructive
+(blanks are not copied) whereas \fBoverwrite\fP is destructive.
+.SS copywin
+.PP
+The \fBcopywin\fP routine provides a finer granularity of control over the
+\fBoverlay\fP and \fBoverwrite\fP routines.
+As in the \fBprefresh\fP routine,
+a rectangle is specified in the destination window, (\fIdminrow\fP,
+\fIdmincol\fP) and (\fIdmaxrow\fP, \fIdmaxcol\fP), and the upper-left-corner

+.SH DESCRIPTION
+.SS newpad
+The \fBnewpad\fP routine creates and returns a pointer to a new pad data
+structure with the given number of lines, \fInlines\fP, and columns,
+\fIncols\fP.
+A pad is like a window, except that it is not restricted by the
+screen size, and is not necessarily associated with a particular part of the
+screen.
+Pads can be used when a large window is needed, and only a part of the
+window will be on the screen at one time.
+Automatic refreshes of pads
+(e.g., from scrolling or echoing of input) do not occur.
+.PP
+It is not
+legal to call \fBwrefresh\fP with a \fIpad\fP as an argument; the routines
+\fBprefresh\fP or \fBpnoutrefresh\fP should be called instead.
+Note that these
+routines require additional parameters to specify the part of the pad to be
+displayed and the location on the screen to be used for the display.
+.SS subpad
+.PP
+The \fBsubpad\fP routine creates and returns a pointer to a subwindow within a
+pad with the given number of lines, \fInlines\fP, and columns, \fIncols\fP.
+Unlike \fBsubwin\fP, which uses screen coordinates, the window is at position
+(\fIbegin\fR_\fIx\fB,\fR \fIbegin\fR_\fIy\fR) on the pad.
+The window is
+made in the middle of the window \fIorig\fP, so that changes made to one window
+affect both windows.
+During the use of this routine, it will often be
+necessary to call \fBtouchwin\fP or \fBtouchline\fP on \fIorig\fP before
+calling \fBprefresh\fP.
+.SS prefresh, pnoutrefresh
+.PP
+The \fBprefresh\fP and \fBpnoutrefresh\fP routines are analogous to
+\fBwrefresh\fP and \fBwnoutrefresh\fP except that they relate to pads instead
+of windows.
+The additional parameters are needed to indicate what part of the
+pad and screen are involved.
+.bP
+The \fIpminrow\fP and \fIpmincol\fP parameters specify the upper
+left-hand corner of the rectangle to be displayed in the pad.
+.bP
+The \fIsminrow\fP,
+\fIsmincol\fP, \fIsmaxrow\fP, and \fIsmaxcol\fP
+parameters specify the edges of the
+rectangle to be displayed on the screen.
+.PP
+The lower right-hand corner of the
+rectangle to be displayed in the pad is calculated from the screen coordinates,
+since the rectangles must be the same size.
+Both rectangles must be entirely
+contained within their respective structures.
+Negative values of
+\fIpminrow\fP, \fIpmincol\fP, \fIsminrow\fP, or \fIsmincol\fP are treated as if
+they were zero.
+.SS pechochar
+.PP
+The \fBpechochar\fP routine is functionally equivalent to a call to \fBaddch\fP
+followed by a call to \fBrefresh\fP(3X),
+a call to \fBwaddch\fP followed by a call
+to \fBwrefresh\fP, or a call to \fBwaddch\fP followed by a call to
+\fBprefresh\fP.
+The knowledge that only a single character is being output is
+taken into consideration and, for non-control characters, a considerable
+performance gain might be seen by using these routines instead of their
+equivalents.
+In the case of \fBpechochar\fP, the last location of the pad on
+the screen is reused for the arguments to \fBprefresh\fP.
+.SS pecho_wchar
+.PP
+The \fBpecho_wchar\fP function is the analogous wide-character
+form of \fBpechochar\fP.
+It outputs one character to a pad and immediately refreshes the pad.
+It does this by a call to \fBwadd_wch\fP followed by a call to \fBprefresh\fP.
+.SH RETURN VALUE
+Routines that return an integer return \fBERR\fP upon failure and \fBOK\fP
+(SVr4 only specifies "an integer value other than \fBERR\fP") upon successful
+completion.
+.PP
+Routines that return pointers return \fBNULL\fP on error, and set \fBerrno\fP
+to \fBENOMEM\fP.
+.PP
+X/Open does not define any error conditions.
+In this implementation
+.RS 3
+.TP 5
+\fBprefresh\fP and \fBpnoutrefresh\fP
+return an error
+if the window pointer is null, or
+if the window is not really a pad or
+if the area to refresh extends off-screen or
+if the minimum coordinates are greater than the maximum.
+.TP 5
+\fBpechochar\fP
+returns an error
+if the window is not really a pad, and the associated call
+to \fBwechochar\fP returns an error.
+.TP 5
+\fBpecho_wchar\fP
+returns an error
+if the window is not really a pad, and the associated call
+to \fBwecho_wchar\fP returns an error.
+.RE
+.SH NOTES
+Note that \fBpechochar\fP may be a macro.
+.SH PORTABILITY
+BSD curses has no \fIpad\fP feature.
+.PP
+SVr2 curses (1986) provided the \fBnewpad\fP and related functions,
+documenting them in a single line each.
+SVr3 (1987) provided more extensive documentation.
+.PP
+The documentation does not explain the term \fIpad\fP.
+However, the Apollo \fIAegis\fP workstation operating system
+supported a graphical \fIpad\fP feature:
+.bP
+These graphical pads could be much larger than the computer's display.
+.bP
+The read-only output from a command could be scrolled back to inspect,
+and select text from the pad.
+.PP
+The two uses may be related.
+.PP
+The XSI Curses standard, Issue 4 describes these functions,
+without significant change from the SVr3 documentation.
+It describes no error conditions.
+The behavior of \fBsubpad\fP if the parent window is not
+a pad is undocumented,
+and is not checked by the vendor Unix implementations:
+.bP
+SVr4 curses sets a flag in the \fBWINDOW\fP structure in \fBnewpad\fP
+which tells if the window is a \fIpad\fP.
+.IP
+However, it uses this information only in
+\fBwaddch\fP (to decide if it should call \fBwrefresh\fP) and
+\fBwscrl\fP (to avoid scrolling a pad),
+and does not check in \fBwrefresh\fP to ensure that the pad
+is refreshed properly.
+.bP
+Solaris X/Open Curses checks if a window is a pad in \fBwnoutrefresh\fP,
+returning \fBERR\fP in that case.
+.IP
+However, it only sets the flag for subwindows if the parent window is a pad.
+Its \fBnewpad\fP function does not set this information.
+Consequently, the check will never fail.
+.IP
+It makes no comparable check in \fBpnoutrefresh\fP,
+though interestingly enough, a comment in the source code
+states that the lack of a check was an MKS extension.
+.bP
+NetBSD 7 curses
+sets a flag in the \fBWINDOW\fP structure for \fBnewpad\fP and \fBsubpad\fP,
+using this to help with the distinction between \fBwnoutrefresh\fP
+and \fBpnoutrefresh\fP.
+.IP
+It does not check for the case where a subwindow is created in
+a pad using \fBsubwin\fP or \fBderwin\fP.
+.IP
+The \fBdupwin\fP function returns a regular window when duplicating a pad.
+Likewise, \fBgetwin\fP always returns a window, even if the saved
+data was from a pad.
+.PP
+This implementation
+.bP
+sets a flag in the \fBWINDOW\fP structure for \fBnewpad\fP and \fBsubpad\fP,
+.bP
+allows a \fBsubwin\fP or \fBderwin\fP call to succeed having a pad parent by
+forcing the subwindow to be a pad,
+.bP
+checks in both \fBwnoutrefresh\fP and \fBpnoutrefresh\fP to ensure
+that pads and windows are handled distinctly, and
+.bP
+ensures that \fBdupwin\fP and \fBgetwin\fP treat
+pads versus windows consistently.

+\fBmcprint\fP \- ship binary data to printer
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint mcprint(char *\fIdata\fB, int \fIlen\fB);\fR
+.SH DESCRIPTION
+This function uses the \fBmc5p\fP or \fBmc4\fP and \fBmc5\fP capabilities,
+if they are present, to ship given data to a printer attached to the terminal.
+.PP
+Note that the \fBmcprint\fP code has no way to do flow control with the printer
+or to know how much buffering it has.
+Your application is responsible for
+keeping the rate of writes to the printer below its continuous throughput rate
+(typically about half of its nominal cps rating).
+Dot-matrix printers and
+6-page-per-minute lasers can typically handle 80cps, so a good conservative
+rule of thumb is to sleep for a second after shipping each 80-character line.
+.
+.SH RETURN VALUE
+The \fBmcprint\fP function returns \fBERR\fP if the write operation aborted
+for some reason.
+In this case, \fBerrno\fP will contain either an error associated
+with \fBwrite\fP(2) or one of the following:
+.TP 5
+ENODEV
+Capabilities for printer redirection do not exist.
+.TP 5
+ENOMEM
+Couldn't allocate sufficient memory to buffer the printer write.
+.PP
+When \fBmcprint\fP succeeds, it returns the number of characters actually
+sent to the printer.
+.SH PORTABILITY
+The \fBmcprint\fP call was designed for \fBncurses\fP(3X), and is not found
+in SVr4 curses, 4.4BSD curses, or any other previous version of curses.
+.SH BUGS
+Padding in the \fBmc5p\fP, \fBmc4\fP and \fBmc5\fP capabilities will not be
+interpreted.

+.SH DESCRIPTION
+The \fBprintw\fP, \fBwprintw\fP, \fBmvprintw\fP and \fBmvwprintw\fP
+routines are analogous to \fBprintf\fP [see \fBprintf\fP(3)].
+In
+effect, the string that would be output by \fBprintf\fP is output
+instead as though \fBwaddstr\fP were used on the given window.
+.PP
+The \fBvwprintw\fP and \fBvw_printw\fP routines are analogous
+to \fBvprintf\fP [see \fBprintf\fP(3)]
+and perform a \fBwprintw\fP using a variable argument list.
+The third argument is a \fBva_list\fP, a pointer to a
+list of arguments, as defined in \fB<stdarg.h>\fP.
+.SH RETURN VALUE
+Routines that return an integer return \fBERR\fP upon failure and \fBOK\fP
+(SVr4 only specifies "an integer value other than \fBERR\fP") upon successful
+completion.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+an error may be returned if it cannot allocate enough memory for the
+buffer used to format the results.
+It will return an error if the window pointer is null.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH HISTORY
+While \fBprintw\fP was implemented in 4BSD,
+it was unused until 4.2BSD (which used it in games).
+That early version of curses was before the ANSI C standard.
+It did not use <varargs.h>, though that was available.
+In 1991 (a couple of years after SVr4 was generally available,
+and after the C standard was published),
+other developers updated the library,
+using <stdarg.h> internally in 4.4BSD curses.
+Even with this improvement,
+BSD curses did not use function prototypes (or even declare
+functions) in the <curses.h> header until 1992.
+.PP
+SVr2 documented
+\fBprintw\fP,
+\fBwprintw\fP
+tersely as \*(``printf on \fIstdscr\fP\*('' and
+tersely as \*(``printf on \fIwin\fP\*('', respectively.
+.PP
+SVr3 added
+\fBmvprintw\fP, and
+\fBmvwprintw\fP, with a three-line summary saying that they were analogous
+to \fBprintf\fP(3),
+explaining that the string which would be output from \fBprintf\fP(3) would
+instead be output using \fBwaddstr\fP on the given window.
+SVr3 also added \fBvwprintw\fP, saying that the third parameter
+is a \fBva_list\fP, defined in <varargs.h>,
+and referring the reader to the manual pages for \fIvarargs\fP and
+\fBvprintf\fP for detailed descriptions.
+.PP
+SVr4 added no new variations of \fBprintw\fP,
+but provided for using <varargs.h> or <stdarg.h> to define the \fBva_list\fP
+type.
+.PP
+X/Open Curses added \fBvw_printw\fP to replace \fBvwprintw\fP,
+stating that its \fBva_list\fP definition requires <stdarg.h>.
+.SH PORTABILITY
+In this implementation, \fBvw_printw\fP and \fBvwprintw\fP are equivalent,
+to support legacy applications.
+However, the latter (\fBvwprintw\fP) is obsolete:
+.bP
+The XSI Curses standard, Issue 4 described these functions.
+The function
+\fBvwprintw\fP is marked TO BE WITHDRAWN, and is to be replaced by a function
+\fBvw_printw\fP using the \fB<stdarg.h>\fP interface.
+.bP
+The Single Unix Specification, Version 2 states that
+\fBvw_printw\fP  is preferred to \fBvwprintw\fP since the latter requires
+including \fB<varargs.h>\fP, which
+cannot be used in the same file as \fB<stdarg.h>\fP.
+This implementation uses \fB<stdarg.h>\fP for both,
+because that header is included in \fB<curses.h\fP>.
+.bP
+X/Open Curses, Issue 5 (December 2007) marked \fBvwprintw\fP (along with
+\fBvwscanw\fP and the termcap interface) as withdrawn.

+.br
+.SH DESCRIPTION
+.SS refresh/wrefresh
+The \fBrefresh\fP and \fBwrefresh\fP routines (or \fBwnoutrefresh\fP and
+\fBdoupdate\fP) must be called to get actual output to the terminal,
+as other routines merely manipulate data structures.
+The routine \fBwrefresh\fP copies
+the named window to the \fIphysical screen\fP,
+taking into account what is already there to do optimizations.
+The \fBrefresh\fP routine is the
+same, using \fBstdscr\fP as the default window.
+Unless \fBleaveok\fP has been
+enabled, the physical cursor of the terminal is left at the location of the
+cursor for that window.
+.SS wnoutrefresh/doupdate
+.PP
+The \fBwnoutrefresh\fP and \fBdoupdate\fP routines allow multiple updates with
+more efficiency than \fBwrefresh\fP alone.
+In addition to all the window
+structures, \fBcurses\fP keeps two data structures representing the terminal
+screen:
+.bP
+a \fIphysical screen\fP, describing what is actually on the screen, and
+.bP
+a \fIvirtual screen\fP, describing what the programmer wants to have on the screen.
+.PP
+The routine \fBwrefresh\fP works by
+.bP
+first calling \fBwnoutrefresh\fP,
+which copies the named window to the \fIvirtual screen\fP, and
+.bP
+then calling \fBdoupdate\fP, which compares
+the \fIvirtual screen\fP to the \fIphysical screen\fP
+and does the actual update.
+.PP
+If the programmer wishes to output several windows at once, a series
+of calls to \fBwrefresh\fP results in alternating calls to \fBwnoutrefresh\fP
+and \fBdoupdate\fP, causing several bursts of output to the screen.
+By first
+calling \fBwnoutrefresh\fP for each window, it is then possible to call
+\fBdoupdate\fP once, resulting in only one burst of output, with fewer total
+characters transmitted and less CPU time used.
+.PP
+If the \fIwin\fP argument to
+\fBwrefresh\fP is the \fIphysical screen\fP
+(i.e., the global variable \fBcurscr\fP),
+the screen is immediately cleared and repainted from scratch.
+.PP
+The phrase \*(``copies the named window
+to the virtual screen\*('' above is ambiguous.
+What actually happens is that all \fItouched\fP (changed) lines in the window
+are copied to the virtual screen.
+This affects programs that use overlapping
+windows; it means that if two windows overlap, you can refresh them in either
+order and the overlap region will be modified only when it is explicitly
+changed.
+(But see the section on \fBPORTABILITY\fP below for a warning about
+exploiting this behavior.)
+.SS wredrawln/redrawwin
+.PP
+The \fBwredrawln\fP routine indicates to \fBcurses\fP that some screen lines
+are corrupted and should be thrown away before anything is written over them.
+It touches the indicated lines (marking them changed).
+The routine \fBredrawwin\fP touches the entire window.
+.SH RETURN VALUE
+Routines that return an integer return \fBERR\fP upon failure, and \fBOK\fP
+(SVr4 only specifies "an integer value other than \fBERR\fP") upon successful
+completion.
+.PP
+X/Open does not define any error conditions.
+In this implementation
+.RS 3
+.TP 5
+\fBwnoutrefresh\fP
+returns an error
+if the window pointer is null, or
+if the window is really a pad.
+.TP 5
+\fBwredrawln\fP
+returns an error
+if the associated call to \fBtouchln\fP returns an error.
+.RE
+.SH NOTES
+Note that \fBrefresh\fP and \fBredrawwin\fP may be macros.
+.SH PORTABILITY
+The XSI Curses standard, Issue 4 describes these functions.
+.PP
+Whether \fBwnoutrefresh\fP copies to the virtual screen the entire contents
+of a window or just its changed portions has never been well-documented in
+historic curses versions (including SVr4).
+It might be unwise to rely on
+either behavior in programs that might have to be linked with other curses
+implementations.
+Instead, you can do an explicit \fBtouchwin\fP before the
+\fBwnoutrefresh\fP call to guarantee an entire-contents copy anywhere.

+/* obsolete */
+.br
+\fBint vwscanw(WINDOW *\fIwin\fB, const char *\fIfmt\fB, va_list \fIvarglist\fB);\fR
+.SH DESCRIPTION
+The \fBscanw\fP, \fBwscanw\fP and \fBmvscanw\fP routines are analogous to
+\fBscanf\fP [see \fBscanf\fP(3)].
+The effect of these routines is as though
+\fBwgetstr\fP were called on the window, and the resulting line used as input
+for \fBsscanf\fP(3).
+Fields which do not map to a variable in the \fIfmt\fP
+field are lost.
+.PP
+The \fBvwscanw\fP and \fBvw_scanw\fP routines are analogous to \fBvscanf\fP(3).
+They perform a \fBwscanw\fP using a variable argument list.
+The third argument is a \fBva_list\fP,
+a pointer to a list of arguments, as defined in \fB<stdarg.h>\fP.
+.SH RETURN VALUE
+\fBvwscanw\fP returns \fBERR\fP on failure and an integer equal to the
+number of fields scanned on success.
+.PP
+Applications may use the return value from the \fBscanw\fP, \fBwscanw\fP,
+\fBmvscanw\fP and \fBmvwscanw\fP routines to determine the number of fields
+which were mapped in the call.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+.SH HISTORY
+While \fBscanw\fP was implemented in 4BSD,
+none of the BSD releases used it until 4.4BSD (in a game).
+That early version of curses was before the ANSI C standard.
+It did not use <varargs.h>, though that was available.
+In 1991 (a couple of years after SVr4 was generally available,
+and after the C standard was published),
+other developers updated the library,
+using <stdarg.h> internally in 4.4BSD curses.
+Even with this improvement,
+BSD curses did not use function prototypes (or even declare
+functions) in the <curses.h> header until 1992.
+.PP
+SVr2 documented
+\fBscanw\fP,
+\fBwscanw\fP
+tersely as \*(``scanf through \fIstdscr\fP\*('' and
+tersely as \*(``scanf through \fIwin\fP\*('', respectively.
+.PP
+SVr3 added
+\fBmvscanw\fP, and
+\fBmvwscanw\fP, with a three-line summary saying that they were analogous
+to \fBscanf\fP(3),
+explaining that the string which would be output from \fBscanf\fP(3) would
+instead be output using \fBwaddstr\fP on the given window.
+SVr3 also added \fBvwscanw\fP, saying that the third parameter
+is a \fBva_list\fP, defined in <varargs.h>,
+and referring the reader to the manual pages for \fIvarargs\fP and
+\fBvprintf\fP for detailed descriptions.
+(Because the SVr3 documentation does not mention \fBvscanf\fP,
+that reference to \fBvprintf\fP may not be an error).
+.PP
+SVr4 added no new variations of \fBscanw\fP,
+but provided for using <varargs.h> or <stdarg.h> to define the \fBva_list\fP
+type.
+.PP
+X/Open Curses added \fBvw_scanw\fP to replace \fBvwscanw\fP,
+stating that its \fBva_list\fP definition requires <stdarg.h>.
+.SH PORTABILITY
+In this implementation, \fBvw_scanw\fP and \fBvwscanw\fP are equivalent,
+to support legacy applications.
+However, the latter (\fBvwscanw\fP) is obsolete:
+.bP
+The XSI Curses standard, Issue 4 described these functions,
+noting that the function
+\fBvwscanw\fP is marked TO BE WITHDRAWN, and is to be replaced by a function
+\fBvw_scanw\fP using the \fB<stdarg.h>\fP interface.
+.bP
+The Single Unix Specification, Version 2 states that
+\fBvw_scanw\fP  is preferred to \fBvwscanw\fP since the latter requires
+including \fB<varargs.h>\fP, which
+cannot be used in the same file as \fB<stdarg.h>\fP.
+This implementation uses \fB<stdarg.h>\fP for both, because that header
+is included in \fB<curses.h\fP>.
+.bP
+X/Open Curses, Issue 5 (December 2007) marked \fBvwscanw\fP (along with
+\fBvwprintw\fP and the termcap interface) as withdrawn.
+.LP
+Both XSI and The Single Unix Specification, Version 2 state that these
+functions return \fBERR\fP or \fBOK\fP.
+.bP
+Since the underlying \fBscanf\fP(3) can return the number of items scanned,
+and the SVr4 code was documented to use this feature,
+this is probably an editing error which was introduced in XSI,
+rather than being done intentionally.
+.bP
+This implementation returns the number of items scanned,
+for compatibility with SVr4 curses.
+As of 2018, NetBSD curses also returns the number of items scanned.
+Both ncurses and NetBSD curses call \fBvsscanf\fP to scan the string,
+which returns \fBEOF\fP on error.
+.bP
+Portable applications should only test if the return value is \fBERR\fP,
+since the \fBOK\fP value (zero) is likely to be misleading.
+.IP
+One possible way to get useful results would be to use a "%n" conversion
+at the end of the format string to ensure that something was processed.

+.br
+.SH DESCRIPTION
+.SS scr_dump
+.PP
+The \fBscr_dump\fP routine dumps the current contents
+of the \fIvirtual screen\fP
+to the file \fIfilename\fP.
+.SS scr_restore
+.PP
+The \fBscr_restore\fP routine sets the \fIvirtual screen\fP to the contents
+of \fIfilename\fP, which must have been written using \fBscr_dump\fP.
+The next call to \fBdoupdate\fP restores
+the \fIphysical screen\fP to the way it looked in the dump file.
+.SS scr_init
+.PP
+The \fBscr_init\fP routine reads in the contents of \fIfilename\fP and uses
+them to initialize the \fBcurses\fP data structures about what the terminal
+currently has on its screen.
+If the data is determined to be valid,
+\fBcurses\fP bases its next update of the screen on this information rather
+than clearing the screen and starting from scratch.
+\fBscr_init\fP is used
+after \fBinitscr\fP(3X) or a \fBsystem\fP(3) call to share
+the screen with another process which has done a \fBscr_dump\fP after its
+\fBendwin\fP(3X) call.
+The data is declared invalid
+.bP
+if the terminfo capabilities \fBrmcup\fP and \fBnrrmc\fP exist, also
+.bP
+if the terminal has been written to since the preceding \fBscr_dump\fP call.
+.SS scr_set
+.PP
+The \fBscr_set\fP routine is a combination of \fBscr_restore\fP and
+\fBscr_init\fP.  It tells the program that the information in \fIfilename\fP is
+what is currently on the screen, and also what the program wants on the screen.
+This can be thought of as a screen inheritance function.
+.PP
+To read (write) a window from (to) a file, use the \fBgetwin\fP and
+\fBputwin\fP routines [see \fBcurs_util\fP(3X)].
+.SH RETURN VALUE
+All routines return the integer \fBERR\fP upon failure and \fBOK\fP
+upon success.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+each will return an error if the file cannot be opened.
+.SH NOTES
+Note that \fBscr_init\fP, \fBscr_set\fP, and \fBscr_restore\fP may be macros.
+.SH PORTABILITY
+The XSI Curses standard, Issue 4, describes these functions (adding the const
+qualifiers).
+.PP
+The SVr4 docs merely say under \fBscr_init\fP that the dump data is also
+considered invalid "if the time-stamp of the tty is old" but do not define
+\*(``old\*(''.

+\fBint scrl(int \fIn\fB);\fR

+\fBint wscrl(WINDOW *\fIwin\fB, int \fIn\fB);\fR
+.br
+.SH DESCRIPTION
+The \fBscroll\fP routine scrolls the window up one line.
+This involves moving
+the lines in the window data structure.
+As an optimization, if the scrolling
+region of the window is the entire screen,
+the \fIphysical screen\fP may be scrolled at the same time.
+.PP
+For positive \fIn\fP, the \fBscrl\fP and \fBwscrl\fP routines scroll the
+window up \fIn\fP lines (line \fIi\fP+\fIn\fP becomes \fIi\fP); otherwise
+scroll the window down \fIn\fP lines.
+This involves moving the lines in the
+window character image structure.
+The current cursor position is not changed.
+.PP
+For these functions to work, scrolling must be enabled via \fBscrollok\fP.
+.SH RETURN VALUE
+These routines return \fBERR\fP upon failure, and \fBOK\fP (SVr4 only specifies
+"an integer value other than \fBERR\fP") upon successful completion.
+.PP
+X/Open defines no error conditions.
+.PP
+This implementation returns an error
+if the window pointer is null, or
+if scrolling is not enabled in the window, e.g., with \fBscrollok\fP.
+.SH NOTES
+Note that \fBscrl\fP and \fBscroll\fP may be macros.
+.PP
+The SVr4 documentation says that the optimization of physically scrolling
+immediately if the scroll region is the entire screen \*(``is\*('' performed, not
+\*(``may be\*('' performed.
+This implementation deliberately does not guarantee
+that this will occur, to leave open the possibility of smarter
+optimization of multiple scroll actions on the next update.
+.PP
+Neither the SVr4 nor the XSI documentation specify whether the current
+attribute or
+current color-pair of blanks generated by the scroll function is zeroed.
+Under this implementation it is.
+.SH PORTABILITY
+The XSI Curses standard, Issue 4 describes these functions.

+.SH DESCRIPTION
+The slk* functions manipulate the set of soft function-key labels that exist on
+many terminals.
+For those terminals that do not have soft labels,
+\fBcurses\fP takes over the bottom line of \fBstdscr\fP, reducing the size of
+\fBstdscr\fP and the variable \fBLINES\fP.
+\fBcurses\fP standardizes on eight
+labels of up to eight characters each.
+In addition to this, the ncurses
+implementation supports a mode where it simulates 12 labels of up to five
+characters each.
+This is useful for PC-like enduser devices.
+ncurses simulates this mode by taking over up to two lines at
+the bottom of the screen;
+it does not try to use any hardware support for this
+mode.
+.SS Initialization
+.PP
+The \fBslk_init\fP routine must be called before \fBinitscr\fP or \fBnewterm\fP
+is called.
+If \fBinitscr\fP eventually uses a line from \fBstdscr\fP to
+emulate the soft labels,
+then \fIfmt\fP determines how the labels are arranged on the screen:
+.RS 3
+.TP 3
+.B 0
+indicates a 3\-2\-3 arrangement of
+the labels.
+.TP 3
+.B 1
+indicates a 4\-4 arrangement
+.TP 3
+.B 2
+indicates the PC-like 4\-4\-4 mode.
+.TP 3
+.B 3
+is again the PC-like 4\-4\-4 mode,
+but in addition an index line is generated, helping the user to
+identify the key numbers easily.
+.RE
+.SS Labels
+.PP
+The \fBslk_set\fP routine
+(and the \fBslk_wset\fP routine for the wide-character library)
+has three parameters:
+.RS 3
+.TP 5
+.I labnum
+is the label number, from \fB1\fP to \fB8\fP
+(12 if \fIfmt\fP in \fBslk_init\fP is \fB2\fP or \fB3\fP);
+.TP
+.I label
+is be the string to put on the label,
+up to eight
+(five if \fIfmt\fP in \fBslk_init\fP is \fB2\fP or \fB3\fP)
+characters in length.
+A null string or a null pointer sets up a blank label.
+.TP
+.I fmt
+is either
+\fB0\fP, \fB1\fP, or \fB2\fP, indicating whether the label is to be
+left-justified, centered, or right-justified, respectively, within the
+label.
+.RE
+.PP
+The \fBslk_label\fP routine returns the current label for label number
+\fIlabnum\fP, with leading and trailing blanks stripped.
+.SS Screen updates
+.PP
+The \fBslk_refresh\fP and \fBslk_noutrefresh\fP routines correspond to
+the \fBwrefresh\fP and \fBwnoutrefresh\fP routines.
+.PP
+The \fBslk_clear\fP routine clears the soft labels from the screen.
+.PP
+The \fBslk_restore\fP routine restores the soft labels to the screen
+after a \fBslk_clear\fP has been performed.
+.PP
+The \fBslk_touch\fP routine forces all the soft labels to be output
+the next time a \fBslk_noutrefresh\fP is performed.
+.SS Video attributes
+.PP
+The
+\fBslk_attron\fP, \fBslk_attrset\fP, \fBslk_attroff\fP and \fBslk_attr\fP
+routines correspond to
+\fBattron\fP, \fBattrset\fP, \fBattroff\fP and \fBattr_get\fP, respectively.
+They have an effect only if soft labels are simulated on the bottom line of
+the screen.
+The default highlight for soft keys is A_STANDOUT (as in
+System V curses, which does not document this fact).
+.SS Colors
+.PP
+The \fBslk_color\fP routine corresponds to \fBcolor_set\fP.
+It has an effect only
+if soft labels are simulated on the bottom line of the screen.
+.PP
+Because \fBslk_color\fP accepts only \fBshort\fP (signed 16-bit integer) values,
+this implementation provides
+\fBextended_slk_color\fP which accepts an integer value, e.g., 32-bits.
+.
+.SH RETURN VALUE
+These routines return \fBERR\fP upon failure
+and \fBOK\fP (SVr4 specifies only "an integer value other than \fBERR\fP")
+upon successful completion.
+.PP
+X/Open defines no error conditions.

+memory for the labels cannot be allocated.
+.RE
+.SH HISTORY
+SVr3 introduced these functions:
+  slk_clear
+  slk_init
+  slk_label
+  slk_noutrefresh
+  slk_refresh
+  slk_restore
+  slk_set
+  slk_touch
+.PP
+SVr4 added these functions:
+  slk_attroff
+  slk_attron
+  slk_attrset
+  slk_start
+.PP
+X/Open Curses added these:
+  slk_attr_off
+  slk_attr_on
+  slk_attr_set
+  slk_color
+  slk_wset
+.SH EXTENSIONS
+.PP
+X/Open Curses documents the \fIopts\fP argument as reserved for future use,
+saying that it must be null.
+This implementation
+uses that parameter in ABI 6 for the functions which have a color-pair
+parameter to support extended color pairs.
+.PP
+For  functions  which modify the color, e.g., \fBslk_attr_set\fP,
+if \fIopts\fP is set it is treated as a pointer to \fBint\fP,
+and used to  set  the  color pair instead of the \fBshort\fP pair parameter.
+.SH NOTES
+Most applications would use \fBslk_noutrefresh\fP because a
+\fBwrefresh\fP is likely to follow soon.
+.SH PORTABILITY
+The XSI Curses standard, Issue 4, described the soft-key functions,
+with some differences from SVr4 curses:
+.bP
+It added functions like the SVr4
+attribute-manipulation functions \fBslk_attron\fP,
+\fBslk_attroff\fP, \fBslk_attrset\fP,
+but which use \fBattr_t\fP parameters (rather than \fBchtype\fP),
+along with a reserved \fIopts\fP parameter.
+.IP
+Two of these new functions (unlike the SVr4 functions) have no provision
+for color: \fBslk_attr_on\fP and \fBslk_attr_off\fP.
+.IP
+The third function (\fBslk_attr_set\fP) has a color-pair parameter.
+.bP
+It added \fBconst\fP qualifiers to parameters (unnecessarily), and
+.bP
+It added \fBslk_color\fP.
+.PP
+Although \fBslk_start\fP is declared in the curses header file,
+it was not documented by SVr4 other than its presence in a list
+of libtermlib.so.1 symbols.
+Reading the source code (i.e., Illumos):
+.bP
+\fBslk_start\fP has two parameters:
+.RS
+.bP
+\fIng\fP (number of groups) and
+.bP
+\fIgp\fP (group pointer).
+.RE
+.bP
+Soft-key groups are an array of \fIng\fP integers.
+.bP
+In SVr4, \fBslk_init\fP calls \fBslk_start\fP passing a null for \fIgp\fP. 
+For this case, \fBslk_start\fP uses the number of groups \fIng\fP
+(3 for the 3-2-3 layout, 2 for the 4-4 layout) which \fBslk_init\fP provided.
+.IP
+If \fIng\fP is neither 2 or 3,
+\fBslk_start\fP checks the terminfo \fIfln\fP (label_format) capability,
+interpreting that as a comma-separated list of numbers,
+e.g., \*(``3,2,3\*('' for the 3-2-3 layout.
+.IP
+Finally, if there is no \fIfln\fP capability, \fBslk_start\fP returns ERR.
+.bP
+If \fBslk_start\fP is given a non-null \fIgp\fP,
+it copies the \fIng\fP elements of the group of soft-keys, up to 16.
+.IP
+If there are more than 16 elements, \fBslk_start\fP returns an error.
+.bP
+The format codes \fB2\fP and \fB3\fP for \fBslk_init\fP
+were added by ncurses in 1996.
+PDCurses 2.4 added this feature in 2001.
+.PP
+The function \fBslk_attr\fP was added by ncurses in 1996.
+.PP
+X/Open Curses does not specify a limit for the number of colors and
+color pairs which a terminal can support.
+However, in its use of \fBshort\fP for the parameters,
+it carries over SVr4's implementation detail for the compiled
+terminfo database, which uses signed 16-bit numbers.
+This implementation provides extended versions of those functions
+which use \fBint\fP parameters,
+allowing applications to use larger color- and pair-numbers.

+.SH DESCRIPTION
+This implementation can be configured to provide a set of functions which
+improve the ability to manage multiple screens.
+This feature can be added to any of the configurations supported by ncurses;
+it adds new entrypoints
+without changing the meaning of any of the existing ones.
+.PP
+.\" ***************************************************************************
+.SS IMPROVED FUNCTIONS
+Most of the functions are new versions of existing functions.
+A parameter is added at the front of the parameter list.
+It is a SCREEN pointer.
+.PP
+The existing functions all use the current screen,
+which is a static variable.
+The extended functions use the specified screen,
+thereby reducing the number of variables which must be modified
+to update multiple screens.
+.\" ***************************************************************************
+.SS NEW FUNCTIONS
+Here are the new functions:
+.TP 5
+ceiling_panel
+this returns a pointer to the topmost panel in the given screen.
+.TP 5
+ground_panel
+this returns a pointer to the lowest panel in the given screen.
+.TP 5
+new_prescr
+when creating a new screen, the library uses static variables which
+have been preset, e.g., by \fBuse_env\fP(3X), \fBfilter\fP(3X), etc.
+With the screen-pointer extension,
+there are situations where it must create a current screen before
+the unextended library does.
+The \fBnew_prescr\fP function is used internally to handle these cases.
+It is also provided as an entrypoint to allow applications to customize
+the library initialization.
+.\" ***************************************************************************
+.SH NOTES
+This extension introduces some new names:
+.TP 5
+NCURSES_SP_FUNCS
+This is set to the library patch-level number.
+In the unextended library, this is zero (0),
+to make it useful for checking if the extension is provided.
+.TP 5
+NCURSES_SP_NAME
+The new functions are named using the macro \fINCURSES_SP_NAME\fP,
+which hides the actual implementation.
+Currently this adds a \*(``_sp\*('' suffix to the name of the unextended function.
+This manual page indexes the extensions showing the full name.
+However the proper usage of these functions uses the macro,
+to provide for the possibility of changing the naming convention
+for specific library configurations.
+.TP 5
+NCURSES_SP_OUTC
+This is a new function-pointer type to use in the screen-pointer functions
+where an \fINCURSES_OUTC\fP is used in the unextended library.
+.TP 5
+NCURSES_OUTC
+This is a function-pointer type used for the cases where a function passes
+characters to the output stream, e.g., \fBvidputs\fP(3X).
+.PP
+.SH PORTABILITY
+These routines are specific to ncurses.
+They were not supported on Version 7, BSD or System V implementations.
+It is recommended that any code depending on ncurses extensions
+be conditioned using \fINCURSES_SP_FUNCS\fP.
+.SH SEE ALSO

+\fBcurs_opaque\fP(3X),
+\fBcurs_threads\fP(3X).

+.SH DESCRIPTION
+.SS baudrate
+The \fBbaudrate\fP routine returns the output speed of the terminal.
+The
+number returned is in bits per second, for example \fB9600\fP, and is an
+integer.
+.SS erasechar, erasewchar
+.PP
+The \fBerasechar\fP routine returns the user's current erase character.
+.PP
+The \fBerasewchar\fP routine stores the current erase character
+in the location referenced by \fIch\fP.
+If no erase character has been defined, the routine fails
+and the location referenced by \fIch\fP is not changed.
+.SS has_is, has_il
+.PP
+The \fBhas_ic\fP routine is true if the terminal has insert- and delete-
+character capabilities.
+.PP
+The \fBhas_il\fP routine is true if the terminal has insert- and delete-line
+capabilities, or can simulate them using scrolling regions.
+This might
+be used to determine if it would be appropriate to turn on physical
+scrolling using \fBscrollok\fP.
+.SS killchar, killwchar
+.PP
+The \fBkillchar\fP routine returns the user's current line kill character.
+.PP
+The \fBkillwchar\fP routine stores the current line-kill character
+in the location referenced by \fIch\fP.
+If no line-kill character has been defined,
+the routine fails and the location referenced by \fIch\fP is not changed.
+.SS longname
+.PP
+The \fBlongname\fP routine returns a pointer to a static area
+containing a verbose description of the current terminal.
+The maximum
+length of a verbose description is 128 characters.
+It is defined only
+after the call to \fBinitscr\fP or \fBnewterm\fP.  The area is
+overwritten by each call to \fBnewterm\fP and is not restored by
+\fBset_term\fP, so the value should be saved between calls to
+\fBnewterm\fP if \fBlongname\fP is going to be used with multiple
+terminals.
+.SS termattrs, term_attrs
+.PP
+If a given terminal does not support a video attribute that an
+application program is trying to use, \fBcurses\fP may substitute a
+different video attribute for it.
+The \fBtermattrs\fP and \fBterm_attrs\fP functions
+return a logical \fBOR\fP of all video attributes supported by the
+terminal using \fBA_\fP and \fBWA_\fP constants respectively.
+This information is useful when a \fBcurses\fP program
+needs complete control over the appearance of the screen.
+.SS termname
+.PP
+The \fBtermname\fP routine returns the terminal name used by \fBsetupterm\fP.
+.SH RETURN VALUE
+\fBlongname\fP and \fBtermname\fP return \fBNULL\fP on error.
+.PP
+Routines that return an integer return \fBERR\fP upon failure and \fBOK\fP
+(SVr4 only specifies "an integer value other than \fBERR\fP") upon successful
+completion.
+.SH NOTES
+Note that \fBtermattrs\fP may be a macro.
+.SH PORTABILITY
+The XSI Curses standard, Issue 4 describes these functions.
+It changes the
+return type of \fBtermattrs\fP to the new type \fBattr_t\fP.
+Most versions of curses truncate the result returned by \fBtermname\fP to
+14 characters.

+.br
+.SH DESCRIPTION
+These routines are included as a conversion aid for programs that use
+the \fItermcap\fP library.
+Their parameters are the same, but the
+routines are emulated using the \fIterminfo\fP database.
+Thus, they
+can only be used to query the capabilities of entries for which a
+terminfo entry has been compiled.
+.SS Initialization
+.PP
+The \fBtgetent\fP routine loads the entry for \fIname\fP.
+It returns:
+.RS 3
+.TP 3
+1
+on success,
+.TP 3
+0
+if there is no such entry
+(or that it is a generic type, having too little information for curses
+applications to run), and
+.TP 3
+\-1
+if the terminfo database could not be found.
+.RE
+.PP
+This differs from the \fItermcap\fP library in two ways:
+.RS 3
+.bP
+The emulation ignores the buffer pointer \fIbp\fP.
+The \fItermcap\fP library would store a copy of the terminal
+description in the area referenced by this pointer.
+However, ncurses stores its terminal descriptions in compiled
+binary form, which is not the same thing.
+.bP
+There is a difference in return codes.
+The \fItermcap\fP library does not check if the terminal
+description is marked with the \fIgeneric\fP capability,
+or if the terminal description has cursor-addressing.
+.RE
+.SS Capability Values
+.PP
+The \fBtgetflag\fP routine gets the boolean entry for \fIid\fP,
+or zero if it is not available.
+.PP
+The \fBtgetnum\fP routine gets the numeric entry for \fIid\fP,
+or \-1 if it is not available.
+.PP
+The \fBtgetstr\fP routine returns the string entry for \fIid\fP,
+or zero if it is not available.
+Use \fBtputs\fP to output the returned string.
+The \fIarea\fP parameter is used as follows:
+.RS 3
+.bP
+It is assumed to be the address of a pointer to a buffer managed by the
+calling application.
+.bP
+However, ncurses checks to ensure that \fBarea\fP is not NULL,
+and also that the resulting buffer pointer is not NULL.
+If either check fails, the \fIarea\fP parameter is ignored.
+.bP
+If the checks succeed, ncurses also copies the return value to
+the buffer pointed to by \fIarea\fP,
+and the \fIarea\fP value will be updated to point past the null ending
+this value.
+.bP
+The return value itself is an address in the terminal description which
+is loaded into memory.
+.RE
+.PP
+Only the first two characters of the \fBid\fP parameter of
+\fBtgetflag\fP,
+\fBtgetnum\fP and
+\fBtgetstr\fP are compared in lookups.
+.SS Formatting Capabilities
+.PP
+The \fBtgoto\fP routine expands the given capability using the parameters.
+.bP
+Because the capability may have padding characters,
+the output of \fBtgoto\fP should be passed to \fBtputs\fP
+rather than some other output function such as \fBprintf\fP(3).
+.bP
+While \fBtgoto\fP is assumed to be used for the two-parameter
+cursor positioning capability,
+termcap applications also use it for single-parameter capabilities.
+.IP
+Doing this shows a quirk in \fBtgoto\fP: most hardware
+terminals use cursor addressing with \fIrow\fP first,
+but the original developers of the termcap interface chose to
+put the \fIcolumn\fP parameter first.
+The \fBtgoto\fP function swaps the order of parameters.
+It does this also for calls requiring only a single parameter.
+In that case, the first parameter is merely a placeholder.
+.bP
+Normally the ncurses library is compiled with terminfo support.
+In that case, \fBtgoto\fP uses \fBtparm\fP(3X) (a more capable formatter).
+.IP
+However, \fBtparm\fP is not a \fItermcap\fP feature,
+and portable \fItermcap\fP applications should not rely upon its availability.
+.PP
+The \fBtputs\fP routine is described on the \fBcurs_terminfo\fP(3X) manual
+page.
+It can retrieve capabilities by either termcap or terminfo name.
+.SS Global Variables
+.PP
+The variables
+\fBPC\fP,
+\fBUP\fP and
+\fBBC\fP
+are set by \fBtgetent\fP to the terminfo entry's data for
+\fBpad_char\fP,
+\fBcursor_up\fP and
+\fBbackspace_if_not_bs\fP,
+respectively.
+\fBUP\fP is not used by ncurses.
+\fBPC\fP is used in the \fBtdelay_output\fP function.
+\fBBC\fP is used in the \fBtgoto\fP emulation.
+The variable \fBospeed\fP is set by ncurses in a system-specific coding
+to reflect the terminal speed.
+.SS Releasing Memory
+The termcap functions provide no means for freeing memory,
+because legacy termcap implementations used only the buffer
+areas provided by the caller via \fBtgetent\fP and \fBtgetstr\fP.
+Those buffers are unused in terminfo.
+.PP
+On the other hand, terminfo allocates memory.
+It uses \fBsetupterm\fP to retrieve the data used by \fBtgetent\fP
+and the functions which return capability values such as \fBtgetstr\fP.
+One could use
+.sp
+	\fBdel_curterm(cur_term);\fP
+.sp
+.PP
+to free this memory, but there is an additional complication with ncurses.
+It uses a fixed-size \fIpool\fP of storage locations,
+one per setting of the \fBTERM\fP variable when \fBtgetent\fP is called.
+The \fBscreen\fP(1) program relies upon this arrangement,
+to improve its performance.
+.PP
+An application which uses only the low-level termcap functions could
+free the memory using \fBdel_curterm\fP,
+because the pool is freed using other functions
+(see \fBcurs_memleaks\fP(3X)).
+.
+.SH RETURN VALUE
+Except where explicitly noted,
+routines that return an integer return \fBERR\fP upon failure and \fBOK\fP
+(SVr4 only specifies "an integer value other than \fBERR\fP") upon successful
+completion.
+.PP
+Routines that return pointers return \fBNULL\fP on error.
+.SH BUGS
+If you call \fBtgetstr\fP to fetch \fBca\fP or any other parameterized string,
+be aware that it will be returned in terminfo notation, not the older and
+not-quite-compatible termcap notation.
+This will not cause problems if all
+you do with it is call \fBtgoto\fP or \fBtparm\fP, which both expand
+terminfo-style strings as terminfo.
+(The \fBtgoto\fP function, if configured to support termcap, will check
+if the string is indeed terminfo-style by looking for "%p" parameters or
+"$<..>" delays, and invoke a termcap-style parser if the string does not
+appear to be terminfo).
+.PP
+Because terminfo conventions for representing padding in string capabilities
+differ from termcap's,
+users can be surprised:
+.bP
+\fBtputs("50")\fP in a terminfo system will put out a literal \*(``50\*(''
+rather than busy-waiting for 50 milliseconds.
+.bP
+However, if ncurses is configured to support termcap,
+it may also have been configured to support the BSD-style padding.
+.IP
+In that case, \fBtputs\fP inspects strings passed to it,
+looking for digits at the beginning of the string.
+.IP
+\fBtputs("50")\fP in a termcap system may wait for 50 milliseconds
+rather than put out a literal \*(``50\*(''
+.PP
+Note that termcap has nothing analogous to terminfo's \fBsgr\fP string.
+One consequence of this is that termcap applications assume \fBme\fP
+(terminfo \fBsgr0\fP) does not reset the alternate character set.
+This implementation checks for, and modifies the data shown to the
+termcap interface to accommodate termcap's limitation in this respect.
+.SH PORTABILITY
+.SS Standards
+These functions are provided for supporting legacy applications,
+and should not be used in new programs:
+.bP
+The XSI Curses standard, Issue 4 describes these functions.
+However, they
+are marked TO BE WITHDRAWN and may be removed in future versions.
+.bP
+X/Open Curses, Issue 5 (December 2007) marked the termcap interface
+(along with \fBvwprintw\fP and \fBvwscanw\fP) as withdrawn.
+.PP
+Neither the XSI Curses standard nor the SVr4 man pages documented the return
+values of \fBtgetent\fP correctly, though all three were in fact returned ever
+since SVr1.
+In particular, an omission in the XSI Curses documentation has been
+misinterpreted to mean that \fBtgetent\fP returns \fBOK\fP or \fBERR\fP.
+Because the purpose of these functions is to provide compatibility with
+the \fItermcap\fP library, that is a defect in XCurses, Issue 4, Version 2
+rather than in ncurses.
+.SS Compatibility with BSD Termcap
+.PP
+External variables are provided for support of certain termcap applications.
+However, termcap applications' use of those variables is poorly documented,
+e.g., not distinguishing between input and output.
+In particular, some applications are reported to declare and/or
+modify \fBospeed\fP.
+.PP
+The comment that only the first two characters of the \fBid\fP parameter
+are used escapes many application developers.
+The original BSD 4.2 termcap library (and historical relics thereof)
+did not require a trailing null NUL on the parameter name passed
+to \fBtgetstr\fP, \fBtgetnum\fP and \fBtgetflag\fP.
+Some applications assume that the termcap interface does not require
+the trailing NUL for the parameter name.
+Taking into account these issues:
+.bP
+As a special case,
+\fBtgetflag\fP matched against a single-character identifier
+provided that was at the end of the terminal description.
+You should not rely upon this behavior in portable programs.
+This implementation disallows matches against single-character capability names.
+.bP
+This implementation disallows matches by the termcap interface against
+extended capability names which are longer than two characters.
+.PP
+The BSD termcap function \fBtgetent\fP returns the text of a termcap
+entry in the buffer passed as an argument.
+This library (like other terminfo implementations) does not store
+terminal descriptions as text.
+It sets the buffer contents to a null-terminated string.
+.SS Other Compatibility
+This library includes a termcap.h header,
+for compatibility with other implementations.
+But the header is rarely used because the other implementations
+are not strictly compatible.
+.PP
+The original BSD termcap (through 4.3BSD) had no header file which
+gave function prototypes, because that was a feature of ANSI C.
+BSD termcap was written several years before C was standardized.
+However, there were two different termcap.h header files in the BSD
+sources:
+.bP
+One was used internally by the \fBjove\fP editor in 2BSD through 4.4BSD.
+It defined global symbols for the termcap variables which it used.
+.bP
+The other appeared in 4.4BSD Lite Release 2 (mid-1993)
+as part of \fIlibedit\fP (also known as the \fIeditline\fP library).
+The CSRG source history shows that this was added in mid-1992.
+The \fIlibedit\fP header file was used internally,
+as a convenience for compiling the \fIeditline\fP library.
+It declared function prototypes, but no global variables.
+.PP
+The header file from \fIlibedit\fP was added to NetBSD's termcap
+library in mid-1994.
+.PP
+Meanwhile, GNU termcap was under development, starting in 1990.
+The first release (termcap 1.0) in 1991 included a termcap.h header.
+The second release (termcap 1.1) in September 1992 modified the
+header to use \fBconst\fP for the function prototypes in the header
+where one would expect the parameters to be read-only.
+This was a difference versus the original BSD termcap.
+The prototype for \fBtputs\fP also differed,
+but in that instance, it was \fIlibedit\fP which differed from BSD termcap.
+.PP
+A copy of GNU termcap 1.3 was bundled with \fIbash\fP in mid-1993,
+to support the \fBreadline\fP(3) library.
+.PP
+A termcap.h file was provided in ncurses 1.8.1 (November 1993).
+That reflected influence by \fBemacs\fP(1) (rather than \fBjove\fP(1))
+and GNU termcap:
+.bP
+it provided declarations for a few global symbols used by \fBemacs\fP
+.bP
+it provided function prototypes (using \fBconst\fP).
+.bP
+a prototype for \fBtparam\fP (a GNU termcap feature) was provided.
+.PP
+Later (in mid-1996) the \fBtparam\fP function was removed from ncurses.
+As a result, there are differences between any of the four implementations,
+which must be taken into account by programs which can work with all
+termcap library interfaces.

+.SH DESCRIPTION
+These low-level routines must be called by programs that have to deal
+directly with the \fBterminfo\fP database to handle certain terminal
+capabilities, such as programming function keys.
+For all other
+functionality, \fBcurses\fP routines are more suitable and their use is
+recommended.
+.PP
+None of these functions use (or are aware of) multibyte character strings
+such as UTF-8:
+.bP
+capability names use the POSIX portable character set
+.bP
+capability string values have no associated encoding;
+they are strings of 8-bit characters.
+.SS Initialization
+.PP
+Initially, \fBsetupterm\fP should be called.
+The high-level curses functions \fBinitscr\fP and
+\fBnewterm\fP call \fBsetupterm\fP to initialize the
+low-level set of terminal-dependent variables
+[listed in \fBterminfo\fP(\*n)].
+.PP
+Applications can use the
+terminal capabilities either directly (via header definitions),
+or by special functions.
+The header files \fBcurses.h\fP and \fBterm.h\fP should be included (in this
+order) to get the definitions for these strings, numbers, and flags.
+.PP
+The \fBterminfo\fP variables
+\fBlines\fP and \fBcolumns\fP are initialized by \fBsetupterm\fP as
+follows:
+.bP
+If \fBuse_env(FALSE)\fP has been called, values for
+\fBlines\fP and \fBcolumns\fP specified in \fBterminfo\fP are used.
+.bP
+Otherwise, if the environment variables \fBLINES\fP and \fBCOLUMNS\fP
+exist, their values are used.
+If these environment variables do not
+exist and the program is running in a window, the current window size
+is used.
+Otherwise, if the environment variables do not exist, the
+values for \fBlines\fP and \fBcolumns\fP specified in the
+\fBterminfo\fP database are used.
+.PP
+Parameterized strings should be passed through \fBtparm\fP to instantiate them.
+All \fBterminfo\fP strings
+(including the output of \fBtparm\fP)
+should be printed
+with \fBtputs\fP or \fBputp\fP.
+Call \fBreset_shell_mode\fP to restore the
+tty modes before exiting [see \fBcurs_kernel\fP(3X)].
+.PP
+Programs which use
+cursor addressing should
+.bP
+output \fBenter_ca_mode\fP upon startup and
+.bP
+output \fBexit_ca_mode\fP before exiting.
+.PP
+Programs which execute shell subprocesses should
+.bP
+call \fBreset_shell_mode\fP and
+output \fBexit_ca_mode\fP before the shell
+is called and
+.bP
+output \fBenter_ca_mode\fP and
+call \fBreset_prog_mode\fP after returning from the shell.
+.PP
+The \fBsetupterm\fP routine reads in the \fBterminfo\fP database,
+initializing the \fBterminfo\fP structures, but does not set up the
+output virtualization structures used by \fBcurses\fP.
+These are its parameters:
+.RS 3
+.TP 5
+\fIterm\fP
+is the terminal type, a character string.
+If \fIterm\fP is null, the environment variable \fBTERM\fP is used.
+.TP 5
+\fIfiledes\fP
+is the file descriptor used for all output.
+.TP 5
+\fIerrret\fP
+points to an optional location where an error status can be returned to
+the caller.
+If \fIerrret\fP is not null,
+then \fBsetupterm\fP returns \fBOK\fP or
+\fBERR\fP and stores a status value in the integer pointed to by
+\fIerrret\fP.
+A return value of \fBOK\fP combined with status of \fB1\fP in \fIerrret\fP
+is normal.
+.IP
+If \fBERR\fP is returned, examine \fIerrret\fP:
+.RS
+.TP 5
+.B 1
+means that the terminal is hardcopy, cannot be used for curses applications.
+.IP
+\fBsetupterm\fP determines if the entry is a hardcopy type by
+checking the \fBhc\fP (\fBhardcopy\fP) capability.
+.TP 5
+.B 0
+means that the terminal could not be found,
+or that it is a generic type,
+having too little information for curses applications to run.
+.IP
+\fBsetupterm\fP determines if the entry is a generic type by
+checking the \fBgn\fP (\fBgeneric\fP) capability.
+.TP 5
+.B \-1
+means that the \fBterminfo\fP database could not be found.
+.RE
+.IP
+If \fIerrret\fP is
+null, \fBsetupterm\fP prints an error message upon finding an error
+and exits.
+Thus, the simplest call is:
+.sp
+      \fBsetupterm((char *)0, 1, (int *)0);\fP,
+.sp
+which uses all the defaults and sends the output to \fBstdout\fP.
+.RE
+.\" ***************************************************************************
+.SS The Terminal State
+.PP
+The \fBsetupterm\fP routine stores its information about the terminal
+in a \fBTERMINAL\fP structure pointed to by the global variable \fBcur_term\fP.
+If it detects an error,
+or decides that the terminal is unsuitable (hardcopy or generic),
+it discards this information,
+making it not available to applications.
+.PP
+If \fBsetupterm\fP is called repeatedly for the same terminal type,
+it will reuse the information.
+It maintains only one copy of a given terminal's capabilities in memory.
+If it is called for different terminal types,
+\fBsetupterm\fP allocates new storage for each set of terminal capabilities.
+.PP
+The \fBset_curterm\fP routine sets \fBcur_term\fP to
+\fInterm\fP, and makes all of the \fBterminfo\fP boolean, numeric, and
+string variables use the values from \fInterm\fP.
+It returns the old value of \fBcur_term\fP.
+.PP
+The \fBdel_curterm\fP routine frees the space pointed to by
+\fIoterm\fP and makes it available for further use.
+If \fIoterm\fP is
+the same as \fBcur_term\fP, references to any of the \fBterminfo\fP
+boolean, numeric, and string variables thereafter may refer to invalid
+memory locations until another \fBsetupterm\fP has been called.
+.PP
+The \fBrestartterm\fP routine is similar to \fBsetupterm\fP and \fBinitscr\fP,
+except that it is called after restoring memory to a previous state (for
+example, when reloading a game saved as a core image dump).
+\fBrestartterm\fP assumes that the windows and the input and output options
+are the same as when memory was saved,
+but the terminal type and baud rate may be different.
+Accordingly, \fBrestartterm\fP saves various tty state bits,
+calls \fBsetupterm\fP, and then restores the bits.
+.\" ***************************************************************************
+.SS Formatting Output
+.PP
+The \fBtparm\fP routine instantiates the string \fIstr\fP with
+parameters \fIpi\fP.  A pointer is returned to the result of \fIstr\fP
+with the parameters applied.
+Application developers should keep in mind these quirks of the interface:
+.bP
+Although \fBtparm\fP's actual parameters may be integers or strings,
+the prototype expects \fBlong\fP (integer) values.
+.bP
+Aside from the \fBset_attributes\fP (\fBsgr\fP) capability,
+most terminal capabilities require no more than one or two parameters.
+.bP
+Padding information is ignored by \fBtparm\fP;
+it is interpreted by \fBtputs\fP.
+.bP
+The capability string is null-terminated.
+Use \*(``\\200\*('' where an ASCII NUL is needed in the output.
+.PP
+\fBtiparm\fP is a newer form of \fBtparm\fP which uses \fI<stdarg.h>\fP
+rather than a fixed-parameter list.
+Its numeric parameters are integers (int) rather than longs.
+.\" ***************************************************************************
+.SS Output Functions
+.PP
+The \fBtputs\fP routine applies padding information
+(i.e., by interpreting marker embedded in the terminfo capability
+such as \*(``$<5>\*('' as 5 milliseconds)
+to the string
+\fIstr\fP and outputs it:
+.bP
+The \fIstr\fP parameter must be a terminfo string
+variable or the return value from
+\fBtparm\fP, \fBtiparm\fP, \fBtgetstr\fP, or \fBtgoto\fP.
+.IP
+The \fBtgetstr\fP and \fBtgoto\fP functions are part of the \fItermcap\fP
+interface,
+which happens to share this function name with the \fIterminfo\fP interface.
+.bP
+\fIaffcnt\fP is the number of lines affected, or 1 if
+not applicable.
+.bP
+\fIputc\fP is a \fBputchar\fP-like routine to which
+the characters are passed, one at a time.
+.PP
+The \fBputp\fR routine calls \fBtputs(\fIstr\fB, 1, putchar)\fR.
+The output of \fBputp\fP always goes to \fBstdout\fP, rather than
+the \fIfiledes\fP specified in \fBsetupterm\fP.
+.PP
+The \fBvidputs\fP routine displays the string on the terminal in the
+video attribute mode \fIattrs\fP, which is any combination of the
+attributes listed in \fBcurses\fP(3X).
+The characters are passed to
+the \fBputchar\fP-like routine \fIputc\fP.
+.PP
+The \fBvidattr\fP routine is like the \fBvidputs\fP routine, except
+that it outputs through \fBputchar\fP.
+.PP
+The \fBvid_attr\fP and \fBvid_puts\fP routines correspond
+to vidattr and vidputs, respectively.
+They use a set of arguments for representing the video attributes plus color,
+i.e.,
+.bP
+\fIattrs\fP of type \fBattr_t\fP for the attributes and
+.bP
+\fIpair\fP of type \fBshort\fP for the color-pair number.
+.PP
+The \fBvid_attr\fP and \fBvid_puts\fP routines
+are designed to use the attribute constants with the \fBWA_\fP prefix.
+.PP
+X/Open Curses reserves the \fIopts\fP argument for future use,
+saying that applications must provide a null pointer for that argument.
+As an extension,
+this implementation allows \fIopts\fP to be used as a pointer to \fBint\fP,
+which overrides the \fIpair\fP (\fBshort\fP) argument.
+.PP
+The \fBmvcur\fP routine provides low-level cursor motion.
+It takes effect immediately (rather than at the next refresh).
+.PP
+While \fBputp\fP and \fBmvcur\fP are low-level functions which
+do not use the high-level curses state,
+they are declared in \fB<curses.h>\fP because SystemV did this
+(see \fIHISTORY\fP).
+.\" ***************************************************************************

+.PP
+The \fBtigetflag\fP, \fBtigetnum\fP and \fBtigetstr\fP routines return
+the value of the capability corresponding to the \fBterminfo\fP

+The \fIcapname\fP for each capability is given in the table column entitled
+\fIcapname\fP code in the capabilities section of \fBterminfo\fP(\*n).

+.SH HISTORY
+.PP
+SVr2 introduced the terminfo feature.
+Its programming manual mentioned these low-level functions:
+.TS
+l l
+_ _
+l l.
+\fBFunction\fP	\fBDescription\fP
+fixterm	restore tty to \*(``in curses\*('' state
+gettmode	establish current tty modes
+mvcur	low level cursor motion
+putp	T{
+utility function that uses \fBtputs\fP to send characters via \fBputchar\fP.
+T}
+resetterm	set tty modes to \*(``out of curses\*('' state
+resetty	reset tty flags to stored value
+saveterm	save current modes as \*(``in curses\*('' state

+vidattr	like \fBvidputs\fP, but outputs through \fBputchar\fP
+vidputs	T{
+output a string to put terminal in a specified video attribute mode
+T}
+.TE
+.PP
+The programming manual also mentioned
+functions provided for termcap compatibility
+(commenting that they \*(``may go away at a later date\*(''):
+.TS
+l l
+_ _
+l l.
+\fBFunction\fP	\fBDescription\fP
+tgetent	look up termcap entry for given \fIname\fP
+tgetflag	get boolean entry for given \fIid\fP
+tgetnum	get numeric entry for given \fIid\fP
+tgetstr	get string entry for given \fIid\fP
+tgoto	apply parameters to given capability
+tputs	T{
+apply padding to capability, calling a function to put characters
+T}
+.TE
+.PP
+Early terminfo programs obtained capability values from the
+\fBTERMINAL\fP structure initialized by \fBsetupterm\fP.
+.PP
+SVr3 extended terminfo by adding functions to retrieve capability values
+(like the termcap interface),
+and reusing tgoto and tputs:
+.TS
+l l
+_ _
+l l.
+\fBFunction\fP	\fBDescription\fP
+tigetflag	get boolean entry for given \fIid\fP
+tigetnum	get numeric entry for given \fIid\fP
+tigetstr	get string entry for given \fIid\fP
+.TE
+.PP
+SVr3 also replaced several of the SVr2 terminfo functions
+which had no counterpart in the termcap interface,
+documenting them as obsolete:
+.TS
+l l
+_ _
+l l.
+\fBFunction\fP	\fBReplaced by\fP
+crmode	cbreak
+fixterm	reset_prog_mode
+gettmode	N/A
+nocrmode	nocbreak
+resetterm	reset_shell_mode
+saveterm	def_prog_mode
+setterm	setupterm
+.TE
+.PP
+SVr3 kept the \fBmvcur\fP, \fBvidattr\fP and \fBvidputs\fP functions,
+along with \fBputp\fP, \fBtparm\fP and \fBtputs\fP.
+The latter were needed to support padding,
+and handling functions such as \fBvidattr\fP
+(which used more than the two parameters supported by \fBtgoto\fP).
+.PP
+SVr3 introduced the functions for switching between terminal
+descriptions, e.g., \fBset_curterm\fP.
+Some of that was incremental improvements to the SVr2 library:
+.bP
+The \fBTERMINAL\fP type definition was introduced in SVr3.01,
+for the \fBterm\fP structure provided in SVr2.
+.bP
+The various global variables such as \fBboolnames\fP were mentioned
+in the programming manual at this point,
+though the variables were provided in SVr2.
+.PP
+SVr4 added the \fBvid_attr\fP and \fBvid_puts\fP functions.
+.PP
+There are other low-level functions declared in the curses header files
+on Unix systems,
+but none were documented.
+The functions marked \*(``obsolete\*('' remained in use
+by the Unix \fBvi\fP(1) editor.
+.SH PORTABILITY
+.SS Legacy functions
+.PP
+X/Open notes that \fBvidattr\fP and \fBvidputs\fP may be macros.
+.PP
+The function \fBsetterm\fP is not described by X/Open and must
+be considered non-portable.
+All other functions are as described by X/Open.
+.SS Legacy data
+.PP
+\fBsetupterm\fP copies the terminal name to the array \fBttytype\fP.
+This is not part of X/Open Curses, but is assumed by some applications.
+.PP
+Other implementions may not declare the capability name arrays.
+Some provide them without declaring them.
+X/Open does not specify them.
+.PP
+Extended terminal capability names, e.g., as defined by \fB@TIC@\ \-x\fP,
+are not stored in the arrays described here.
+.SS Output buffering
+.PP
+Older versions of \fBncurses\fP assumed that the file descriptor passed to
+\fBsetupterm\fP from \fBinitscr\fP or \fBnewterm\fP uses buffered I/O,
+and would write to the corresponding stream.
+In addition to the limitation that the terminal was left in block-buffered
+mode on exit (like System V curses),
+it was problematic because \fBncurses\fP
+did not allow a reliable way to cleanup on receiving SIGTSTP.
+.PP
+The current version (ncurses6)
+uses output buffers managed directly by \fBncurses\fP.
+Some of the low-level functions described in this manual page write
+to the standard output.
+They are not signal-safe.
+The high-level functions in \fBncurses\fP use
+alternate versions of these functions
+using the more reliable buffering scheme.
+.SS Function prototypes
+.PP
+The X/Open Curses prototypes are based on the SVr4 curses header declarations,
+which were defined at the same time the C language was first standardized in
+the late 1980s.
+.bP
+X/Open Curses uses \fBconst\fP less effectively than a later design might,
+in some cases applying it needlessly to values are already constant,
+and in most cases overlooking parameters which normally would use \fBconst\fP.
+Using constant parameters for functions which do not use \fBconst\fP
+may prevent the program from compiling.
+On the other hand, \fIwritable strings\fP are an obsolescent feature.
+.IP
+As an extension, this implementation can be configured to change the
+function prototypes to use the \fBconst\fP keyword.
+The ncurses ABI 6 enables this feature by default.
+.bP
+X/Open Curses prototypes \fBtparm\fP with a fixed number of parameters,
+rather than a variable argument list.
+.IP
+This implementation uses a variable argument list, but can be
+configured to use the fixed-parameter list.
+Portable applications should provide 9 parameters after the format;
+zeroes are fine for this purpose.
+.IP
+In response to review comments by Thomas E. Dickey,
+X/Open Curses Issue 7 proposed the \fBtiparm\fP function in mid-2009.
+.SS Special TERM treatment
+.PP
+If configured to use the terminal-driver,
+e.g., for the MinGW port,
+.bP
+\fBsetupterm\fP interprets a missing/empty TERM variable as the
+special value \*(``unknown\*(''.
+.bP
+\fBsetupterm\fP allows explicit use of the
+the windows console driver by checking if $TERM is set to
+\*(``#win32con\*('' or an abbreviation of that string.
+.SS Other portability issues
+.PP
+In System V Release 4, \fBset_curterm\fP has an \fBint\fP return type and
+returns \fBOK\fP or \fBERR\fP.  We have chosen to implement the X/Open Curses
+semantics.
+.PP
+In System V Release 4, the third argument of \fBtputs\fP has the type
+\fBint (*putc)(char)\fP.
+.PP
+At least one implementation of X/Open Curses (Solaris) returns a value
+other than \fBOK\fP/\fBERR\fP from \fBtputs\fP.
+That returns the length of the string, and does no error-checking.
+.PP
+X/Open notes that after calling \fBmvcur\fP, the curses state may not match the
+actual terminal state, and that an application should touch and refresh
+the window before resuming normal curses calls.
+Both \fBncurses\fP and System V Release 4 curses implement \fBmvcur\fP using
+the SCREEN data allocated in either \fBinitscr\fP or \fBnewterm\fP.
+So though it is documented as a terminfo function,
+\fBmvcur\fP is really a curses function which is not well specified.
+.PP
+X/Open states that the old location must be given for \fBmvcur\fP.
+This implementation allows the caller to use \-1's for the old ordinates.
+In that case, the old location is unknown.

+.SH DESCRIPTION
+This implementation can be configured to provide rudimentary support
+for multi-threaded applications.
+This makes a different set of libraries, e.g., \fBlibncursest\fP since
+the binary interfaces are different.
+.PP
+Rather than modify the interfaces to pass a thread specifier to
+each function, it adds a few functions which can be used in any
+configuration which hide the mutex's needed to prevent concurrent
+use of the global variables when configured for threading.
+.PP
+In addition to forcing access to members of the \fBWINDOW\fP structure
+to be via functions (see \fBcurs_opaque\fP(3X)),
+it makes functions of the common global variables,
+e.g.,
+COLORS,
+COLOR_PAIRS,
+COLS,
+ESCDELAY,
+LINES,
+TABSIZE
+curscr,
+newscr and
+ttytype.
+Those variables are maintained as read-only values, stored in the \fBSCREEN\fP
+structure.
+.PP
+Even this is not enough to make a thread-safe application using curses.
+A multi-threaded application would be expected to have threads updating
+separate windows (within the same device),
+or updating on separate screens (on different devices).
+Also, a few of the global variables are considered writable by some
+applications.
+The functions described here address these special situations.
+.PP
+The ESCDELAY and TABSIZE global variables are modified by some applications.
+To modify them in any configuration,
+use the \fBset_escdelay\fP or \fBset_tabsize\fP functions.
+Other global variables are not modifiable.
+.PP
+The \fBget_escdelay\fP function returns the value for ESCDELAY.
+.PP
+The \fBuse_window\fP and \fBuse_screen\fP functions provide coarse
+granularity mutexes for their respective \fBWINDOW\fP and \fBSCREEN\fP
+parameters, and call a user-supplied function,
+passing it a \fIdata\fP parameter,
+and returning the value from the user-supplied function to the application.

+\fBbool is_linetouched(WINDOW *\fIwin\fB, int \fIline\fB);\fR

+.br
+.SH DESCRIPTION
+The \fBtouchwin\fP and \fBtouchline\fP routines throw away all
+optimization information about which parts of the window have been
+touched, by pretending that the entire window has been drawn on.
+This
+is sometimes necessary when using overlapping windows, since a change
+to one window affects the other window, but the records of which lines
+have been changed in the other window do not reflect the change.
+The
+routine \fBtouchline\fP only pretends that \fIcount\fP lines have been
+changed, beginning with line \fIstart\fP.
+.PP
+The \fBuntouchwin\fP routine marks all lines in the window as unchanged since
+the last call to \fBwrefresh\fP.
+.PP
+The \fBwtouchln\fP routine makes \fIn\fP lines in the window, starting
+at line \fIy\fR, look as if they have (\fIchanged\fB=1\fR) or have
+not (\fIchanged\fB=0\fR) been changed since the last call to
+\fBwrefresh\fP.
+.PP
+The \fBis_linetouched\fP and \fBis_wintouched\fP routines return
+\fBTRUE\fP if the specified line/window was modified since the last
+call to \fBwrefresh\fP; otherwise they return \fBFALSE\fP.  In
+addition, \fBis_linetouched\fP returns \fBERR\fP if \fIline\fP is not
+valid for the given window.
+.SH RETURN VALUE
+All routines return the integer \fBERR\fP upon failure and an integer value
+other than \fBERR\fP upon successful completion, unless otherwise noted in the
+preceding routine descriptions.
+.PP
+X/Open does not define any error conditions.
+In this implementation
+.RS 3
+.TP 5
+\fBis_linetouched\fP
+returns an error
+if the window pointer is null, or
+if the line number is outside the window.
+.IP
+The constant \fBERR\fP is distinct from \fBTRUE\fP and \fBFALSE\fP,
+which are the normal return values of this function.
+Because the function returns a \fBbool\fP,
+returning \fBERR\fP (which is neither \fBTRUE\fP nor \fBFALSE\fP)
+may not be supported by the compiler.
+.IP
+To provide error-checking and also match the X/Open function prototype,
+the \fBERR\fP is provided by a macro named \fBis_linetouched\fP.
+The actual function returns \fBFALSE\fP when it detects an error.
+.TP 5
+\fBwtouchln\fP
+returns an error
+if the window pointer is null, or
+if the line number is outside the window.
+.RE
+.SH PORTABILITY
+.PP
+These functions were introduced by SVr4.
+The Solaris curses header file,
+for instance, defines both an actual function and macro for each.
+The macros give the same result as the actual functions.
+SVr4 curses does not check the window parameter \fIwin\fP to ensure
+that it is not \fBNULL\fP;
+otherwise this implementation behaves the same as SVr4.
+.PP
+The XSI Curses standard, Issue 4 describes these functions,
+but defines no error conditions.
+.SH NOTES
+All of these routines except \fBwtouchln\fP may be macros.

+.SH DESCRIPTION
+The \fIcurses trace\fP routines are used for debugging the ncurses libraries,
+as well as applications which use the ncurses libraries.
+Some limitations apply:
+.bP
+Aside from \fBcurses_trace\fP,
+the other functions are normally available only with the debugging library
+e.g., \fBlibncurses_g.a\fP.
+.IP
+All of the trace functions may be compiled into any model (shared, static,
+profile) by defining the symbol \fBTRACE\fP.
+.bP
+Additionally, the functions which use \fBcchar_t\fP
+are only available with the wide-character configuration of the libraries.
+.SS Functions
+The principal parts of this interface are
+.bP
+\fBcurses_trace\fP, which selectively enables different tracing features, and
+.bP
+\fB_tracef\fP, which writes formatted data to the \fItrace\fP file.
+.IP
+The other functions either return a pointer to a string-area
+(allocated by the corresponding function), or return no value
+(such as \fB_tracedump\fP,
+which implements the screen dump for \fBTRACE_UPDATE\fP).
+The caller should not free these strings,
+since the allocation is reused on successive calls.
+To work around the problem of a single string-area per function,
+some use a buffer-number parameter, telling the library to allocate
+additional string-areas.
+.PP
+The \fBcurses_trace\fP function is always available,
+whether or not the other trace functions are available:
+.bP
+If tracing is available,
+calling \fBcurses_trace\fP with a nonzero parameter
+updates the trace mask,
+and returns the previous trace mask.
+.IP
+When the trace mask is nonzero,
+ncurses creates the file \*(``trace\*('' in the current directory for output.
+If the file already exists, no tracing is done.
+.bP
+If tracing is not available, \fBcurses_trace\fP returns zero (0).
+.SS Trace Parameter
+The trace parameter is formed by OR'ing
+values from the list of \fBTRACE_\fIxxx\fR definitions in \fB<curses.h>\fR.
+These include:
+.TP 5
+.B TRACE_DISABLE
+turn off tracing by passing a zero parameter.
+.IP
+The library flushes the output file,
+but retains an open file-descriptor to the trace file
+so that it can resume tracing later if a nonzero parameter is passed
+to the \fBcurses_trace\fP function.
+.TP 5
+.B TRACE_TIMES
+trace user and system times of updates.
+.TP 5
+.B TRACE_TPUTS
+trace \fBtputs\fP(3X) calls.
+.TP 5
+.B TRACE_UPDATE
+trace update actions, old & new screens.
+.TP 5
+.B TRACE_MOVE
+trace cursor movement and scrolling.
+.TP 5
+.B TRACE_CHARPUT
+trace all character outputs.
+.TP 5
+.B TRACE_ORDINARY
+trace all update actions.
+The old and new screen contents are written to the trace file
+for each refresh.
+.TP 5
+.B TRACE_CALLS
+trace all curses calls.
+The parameters for each call are traced, as well as return values.
+.TP 5
+.B TRACE_VIRTPUT
+trace virtual character puts, i.e., calls to \fBaddch\fP.
+.TP 5
+.B TRACE_IEVENT
+trace low-level input processing, including timeouts.
+.TP 5
+.B TRACE_BITS
+trace state of TTY control bits.
+.TP 5
+.B TRACE_ICALLS
+trace internal/nested calls.
+.TP 5
+.B TRACE_CCALLS
+trace per-character calls.
+.TP 5
+.B TRACE_DATABASE
+trace read/write of terminfo/termcap data.
+.TP 5
+.B TRACE_ATTRS
+trace changes to video attributes and colors.
+.TP 5
+.B TRACE_MAXIMUM
+maximum trace level, enables all of the separate trace features.
+.PP
+Some tracing features are enabled whenever the \fBcurses_trace\fP parameter
+is nonzero.
+Some features overlap.
+The specific names are used as a guideline.
+.SS Initialization
+These functions check the \fBNCURSES_TRACE\fP environment variable,
+to set the tracing feature as if \fBcurses_trace\fP was called:

+.RE
+.SS Command-line Utilities
+.PP
+The command-line utilities such as \fBtic\fP(1) provide a verbose option
+which extends the set of messages written using the \fBcurses_trace\fP function.
+Both of these (\fB\-v\fP and \fBcurses_trace\fP)
+use the same variable (\fB_nc_tracing\fP),
+which determines the messages which are written.
+.PP
+Because the command-line utilities may call initialization functions
+such as \fBsetupterm\fP, \fBtgetent\fP or \fBuse_extended_names\fP,
+some of their debugging output may be directed to the \fItrace\fP file
+if the \fBNCURSES_TRACE\fP environment variable is set:
+.bP
+messages produced in the utility are written to the standard error.
+.bP
+messages produced by the underlying library are written to \fItrace\fP.
+.PP
+If ncurses is built without tracing, none of the latter are produced,
+and fewer diagnostics are provided by the command-line utilities.
+.SH RETURN VALUE
+Routines which return a value are designed to be used as parameters
+to the \fB_tracef\fP routine.
+.SH PORTABILITY
+These functions are not part of the XSI interface.
+Some other curses implementations are known to
+have similar features,
+but they are not compatible with ncurses:
+.bP
+SVr4 provided \fBtraceon\fP and \fBtraceoff\fP,
+to control whether debugging information was written
+to the \*(``trace\*('' file.
+While the functions were always available,
+this feature was only enabled
+if \fBDEBUG\fP was defined when building the library.
+.IP
+The SVr4 tracing feature is undocumented.
+.bP
+PDCurses provides \fBtraceon\fP and \fBtraceoff\fP,
+which (like SVr4) are always available,
+and enable tracing
+to the \*(``trace\*('' file
+only when a debug-library is built.
+.IP
+PDCurses has a short description of these functions,
+with a note that they are not present in X/Open Curses,
+ncurses or NetBSD.
+It does not mention SVr4,
+but the functions' inclusion in a header file section
+labeled \*(``Quasi-standard\*('' hints at the origin.
+.bP
+NetBSD does not provide functions for enabling/disabling traces.
+It uses environment variables
+\fBCURSES_TRACE_MASK\fP and
+\fBCURSES_TRACE_FILE\fP to determine what is traced,
+and where the results are written.
+This is available only when a debug-library is built.
+.IP
+The NetBSD tracing feature is undocumented.
+.PP
+A few ncurses functions are not provided when symbol versioning is used:

+.SH DESCRIPTION
+.SS unctrl
+.PP
+The \fBunctrl\fP routine returns a character string which is a printable
+representation of the character \fIc\fP, ignoring attributes.
+Control characters are displayed in the \fB^\fIX\fR notation.
+Printing characters are displayed as is.
+The corresponding \fBwunctrl\fP returns a printable representation of
+a wide character.
+.SS keyname/key_name
+.PP
+The \fBkeyname\fP routine returns a character string
+corresponding to the key \fIc\fP:
+.bP
+Printable characters are displayed as themselves,
+e.g., a one-character string containing the key.
+.bP
+Control characters are displayed in the \fB^\fIX\fR notation.
+.bP
+DEL (character 127) is displayed as \fB^?\fP.
+.bP
+Values above 128 are either meta characters
+(if the screen has not been initialized,
+or if \fBmeta\fP(3X) has been called with a \fBTRUE\fP parameter),
+shown in the \fBM\-\fIX\fR notation,
+or are displayed as themselves.
+In the latter case, the values may not be printable;
+this follows the X/Open specification.
+.bP
+Values above 256 may be the names of the names of function keys.
+.bP
+Otherwise (if there is no corresponding name) the function returns null,
+to denote an error.
+X/Open also lists an \*(``UNKNOWN KEY\*('' return value,
+which some implementations return rather than null.
+.LP
+The corresponding \fBkey_name\fP returns a character string corresponding
+to the wide-character value \fIw\fP.
+The two functions do not return the same set of strings;
+the latter returns null where the former would display a meta character.
+.SS filter/nofilter
+.PP
+The \fBfilter\fP routine, if used, must be called before \fBinitscr\fP or
+\fBnewterm\fP are called.
+Calling \fBfilter\fP causes these changes in initialization:
+.bP
+\fBLINES\fP is set to 1;
+.bP
+the capabilities
+\fBclear\fP,
+\fBcud1\fP,
+\fBcud\fP,
+\fBcup\fP,
+\fBcuu1\fP,
+\fBcuu\fP,
+\fBvpa\fP
+are disabled;
+.bP
+the capability \fBed\fP is disabled if \fBbce\fP is set;
+.bP
+and the \fBhome\fP string is set to the value of \fBcr\fP.
+.PP
+The \fBnofilter\fP routine cancels the effect of a preceding \fBfilter\fP
+call.
+That allows the caller to initialize a screen on a different device,
+using a different value of \fB$TERM\fP.
+The limitation arises because the \fBfilter\fP routine modifies the
+in-memory copy of the terminal information.
+.SS use_env
+.PP
+The \fBuse_env\fP routine, if used,
+should be called before \fBinitscr\fP or
+\fBnewterm\fP are called
+(because those compute the screen size).
+It modifies the way \fBncurses\fP treats environment variables
+when determining the screen size.
+.bP
+Normally \fBncurses\fP looks first at the terminal database for the screen size.
+.IP
+If \fBuse_env\fP was called with \fBFALSE\fP for parameter,
+it stops here unless
+\fBuse_tioctl\fP was also called with \fBTRUE\fP for parameter.
+.bP
+Then it asks for the screen size via operating system calls.
+If successful,
+it overrides the values from the terminal database.
+.bP
+Finally (unless \fBuse_env\fP was called with \fBFALSE\fP parameter),
+\fBncurses\fP examines the \fBLINES\fP or \fBCOLUMNS\fP environment variables,
+using a value in those to override the results
+from the operating system or terminal database.
+.IP
+\fBNcurses\fP also updates the screen size in response to \fBSIGWINCH\fP,
+unless overridden by the \fBLINES\fP or \fBCOLUMNS\fP environment variables,
+.SS use_tioctl
+.PP
+The \fBuse_tioctl\fP routine, if used,
+should be called before \fBinitscr\fP or \fBnewterm\fP are called
+(because those compute the screen size).
+After \fBuse_tioctl\fP is called with \fBTRUE\fP as an argument,
+\fBncurses\fP modifies the last step in its computation
+of screen size as follows:
+.bP
+checks if the \fBLINES\fP and \fBCOLUMNS\fP environment variables
+are set to a number greater than zero.
+.bP
+for each, \fBncurses\fP updates the corresponding environment variable
+with the value that it has obtained via operating system call
+or from the terminal database.
+.bP
+\fBncurses\fP re-fetches the value of the environment variables so that
+it is still the environment variables which set the screen size.
+.PP
+The \fBuse_env\fP and \fBuse_tioctl\fP routines combine as
+summarized here:
+.TS
+center tab(/);
+l l l
+_ _ _
+lw7 lw7 lw40.
+\fBuse_env\fP/\fBuse_tioctl\fP/\fBSummary\fP
+TRUE/FALSE/T{
+This is the default behavior.
+\fBncurses\fP uses operating system calls
+unless overridden by $LINES or $COLUMNS environment variables.
+T}
+TRUE/TRUE/T{
+\fBncurses\fP updates $LINES and $COLUMNS based on operating system calls.
+T}
+FALSE/TRUE/T{
+\fBncurses\fP ignores $LINES and $COLUMNS,
+uses operating system calls to obtain size.
+T}
+FALSE/FALSE/T{
+\fBncurses\fP relies on the terminal database to determine size.
+T}
+.TE
+.SS putwin/getwin
+.PP
+The \fBputwin\fP routine writes all data associated
+with window (or pad) \fIwin\fP into
+the file to which \fIfilep\fP points.
+This information can be later retrieved
+using the \fBgetwin\fP function.
+.PP
+The \fBgetwin\fP routine reads window related data stored in the file by
+\fBputwin\fP.
+The routine then creates and initializes a new window using that
+data.
+It returns a pointer to the new window.
+There are a few caveats:
+.bP
+the data written is a copy of the \fBWINDOW\fP structure,
+and its associated character cells.
+The format differs between the wide-character (\fBncursesw\fP) and
+non-wide (\fBncurses\fP) libraries.
+You can transfer data between the two, however.
+.bP
+the retrieved window is always created as a top-level window (or pad),
+rather than a subwindow.
+.bP
+the window's character cells contain the color pair \fIvalue\fP,
+but not the actual color \fInumbers\fP.
+If cells in the retrieved window use color pairs which have not been
+created in the application using \fBinit_pair\fP,
+they will not be colored when the window is refreshed.
+.SS delay_output
+.PP
+The \fBdelay_output\fP routine inserts an \fIms\fP millisecond pause
+in output.
+This routine should not be used extensively because
+padding characters are used rather than a CPU pause.
+If no padding character is specified,
+this uses \fBnapms\fP to perform the delay.
+.SS flushinp
+.PP
+The \fBflushinp\fP routine throws away any typeahead that has been typed by the
+user and has not yet been read by the program.
+.SH RETURN VALUE
+Except for \fBflushinp\fP, routines that return an integer return \fBERR\fP
+upon failure and \fBOK\fP (SVr4 specifies only "an integer value other than
+\fBERR\fP") upon successful completion.
+.PP
+Routines that return pointers return \fBNULL\fP on error.
+.PP
+X/Open does not define any error conditions.
+In this implementation
+.RS 3
+.TP 5
+\fBflushinp\fP
+returns an error if the terminal was not initialized.
+.TP 5
+\fBputwin\fP
+returns an error if the associated \fBfwrite\fP calls return an error.
+.RE
+.SH PORTABILITY
+.SS filter
+.PP
+The SVr4 documentation describes the action of \fBfilter\fP only in the vaguest
+terms.
+The description here is adapted from the XSI Curses standard (which
+erroneously fails to describe the disabling of \fBcuu\fP).
+.SS keyname
+.PP
+The \fBkeyname\fP function may return the names of user-defined
+string capabilities which are defined in the terminfo entry via the \fB\-x\fP
+option of \fB@TIC@\fP.
+This implementation automatically assigns at run-time keycodes to
+user-defined strings which begin with \*(``k\*(''.
+The keycodes start at KEY_MAX, but are not guaranteed to be
+the same value for different runs because user-defined codes are
+merged from all terminal descriptions which have been loaded.
+The \fBuse_extended_names\fP(3X) function controls whether this data is
+loaded when the terminal description is read by the library.
+.SS nofilter/use_tioctl
+.PP
+The \fBnofilter\fP and \fBuse_tioctl\fP routines are specific to \fBncurses\fP.
+They were not supported on Version 7, BSD or System V implementations.
+It is recommended that any code depending on \fBncurses\fP extensions
+be conditioned using NCURSES_VERSION.
+.SS putwin/getwin file-format
+.PP
+The \fBputwin\fP and \fBgetwin\fP functions have several issues with
+portability:
+.bP
+The files written and read by these functions
+use an implementation-specific format.
+Although the format is an obvious target for standardization,
+it has been overlooked.
+.IP
+Interestingly enough, according to the copyright dates in Solaris source,
+the functions (along with \fBscr_init\fP, etc.) originated with
+the University of California, Berkeley (in 1982)
+and were later (in 1988) incorporated into SVr4.
+Oddly, there are no such functions in the 4.3BSD curses sources.
+.bP
+Most implementations simply dump the binary \fBWINDOW\fP structure to the file.
+These include SVr4 curses, NetBSD and PDCurses,
+as well as older \fBncurses\fP versions.
+This implementation
+(as well as the X/Open variant of Solaris curses, dated 1995)
+uses textual dumps.
+.IP
+The implementations which use binary dumps use block-I/O
+(the \fBfwrite\fP and \fBfread\fP functions).
+Those that use textual dumps use buffered-I/O.
+A few applications may happen to write extra data in the file using
+these functions.
+Doing that can run into problems mixing block- and buffered-I/O.
+This implementation reduces the problem on writes by flushing the output.
+However, reading from a file written using mixed schemes may not be successful.
+.SS unctrl/wunctrl
+.PP
+The XSI Curses standard, Issue 4 describes these functions.
+It states that \fBunctrl\fP and \fBwunctrl\fP will return a null pointer if
+unsuccessful, but does not define any error conditions.
+This implementation checks for three cases:
+.bP
+the parameter is a 7-bit US\-ASCII code.
+This is the case that X/Open Curses documented.
+.bP
+the parameter is in the range 128\-159, i.e., a C1 control code.
+If \fBuse_legacy_coding\fP(3X) has been called with a \fB2\fP parameter,
+\fBunctrl\fP returns the parameter, i.e., a one-character string with
+the parameter as the first character.
+Otherwise, it returns \*(``~@\*('', \*(``~A\*('', etc.,
+analogous to \*(``^@\*('', \*(``^A\*('', C0 controls.
+.IP
+X/Open Curses does not document whether \fBunctrl\fP can be called before
+initializing curses.
+This implementation permits that,
+and returns the \*(``~@\*('', etc., values in that case.
+.bP
+parameter values outside the 0 to 255 range.
+\fBunctrl\fP returns a null pointer.
+.PP
+The strings returned by \fBunctrl\fP in this implementation are determined
+at compile time,
+showing C1 controls from the upper-128 codes
+with a \*(``~\*('' prefix rather than \*(``^\*(''.
+Other implementations have different conventions.
+For example, they may show both sets of control characters with \*(``^\*('',
+and strip the parameter to 7 bits.
+Or they may ignore C1 controls and treat all of the upper-128 codes as
+printable.
+This implementation uses 8 bits but does not modify the string to reflect
+locale.
+The \fBuse_legacy_coding\fP(3X) function allows the caller to
+change the output of \fBunctrl\fP.
+.PP
+Likewise, the \fBmeta\fP(3X) function allows the caller to change the
+output of \fBkeyname\fP, i.e.,
+it determines whether to use the \*(``M\-\*('' prefix
+for \*(``meta\*('' keys (codes in the range 128 to 255).
+Both \fBuse_legacy_coding\fP(3X) and \fBmeta\fP(3X) succeed only after
+curses is initialized.
+X/Open Curses does not document the treatment of codes 128 to 159.
+When treating them as \*(``meta\*('' keys
+(or if \fBkeyname\fP is called before initializing curses),
+this implementation returns strings \*(``M\-^@\*('', \*(``M\-^A\*('', etc.
+.PP
+X/Open Curses documents \fBunctrl\fP as declared in \fB<unctrl.h>\fP,
+which \fBncurses\fP does.
+However, \fBncurses\fP' \fB<curses.h>\fP includes \fB<unctrl.h>\fP,
+matching the behavior of SVr4 curses.
+Other implementations may not do that.
+.SS use_env/use_tioctl
+.PP
+If \fBncurses\fP is configured to provide the sp-functions extension,
+the state of \fBuse_env\fP and \fBuse_tioctl\fP may be updated before
+creating each \fIscreen\fP rather than once only
+(\fBcurs_sp_funcs\fP(3X)).
+This feature of \fBuse_env\fP
+is not provided by other implementation of curses.

+.SH DESCRIPTION
+This page summarizes variables provided by the \fBcurses\fP library.
+A more complete description is given in the \fBcurses\fP(3X) manual page.
+.PP
+Depending on the configuration, these may be actual variables,
+or macros (see \fBcurs_threads\fP(3X) and \fBcurs_opaque\fP(3X))
+which provide read-only access to \fIcurses\fP's state.
+In either case, applications should treat them as read-only to avoid
+confusing the library.
+.SS COLOR_PAIRS
+After initializing curses, this variable contains the number of color pairs
+which the terminal can support.
+Usually the number of color pairs will be the product \fBCOLORS\fP*\fBCOLORS\fP,
+however this is not always true:
+.bP
+a few terminals use HLS colors, which do not follow this rule
+.bP
+terminals supporting a large number of colors are limited by the number
+of color pairs that can be represented in a \fIsigned short\fP value.
+.SS COLORS
+After initializing curses, this variable contains the number of colors
+which the terminal can support.
+.SS COLS
+After initializing curses, this variable contains the width of the screen,
+i.e., the number of columns.
+.SS ESCDELAY
+This variable holds the number of milliseconds to wait after reading an
+escape character,
+to distinguish between an individual escape character entered on the
+keyboard from escape sequences sent by cursor- and function-keys
+(see curses(3X)).
+.SS LINES
+After initializing curses, this variable contains the height of the screen,
+i.e., the number of lines.
+.SS TABSIZE
+This variable holds the number of columns used by the \fIcurses\fP library
+when converting a tab character to spaces as it adds the tab to a window
+(see \fBcurs_addch\fP(3X).
+.SS The Current Screen
+This implementation of curses uses a special window \fBcurscr\fP to
+record its updates to the terminal screen.
+.PP
+This is referred to as the \*(``physical screen\*('' in the
+\fBcurs_refresh\fP(3X) and
+\fBcurs_outopts\fP(3X) manual pages.
+.SS The New Screen
+This implementation of curses uses a special window \fBnewscr\fP to
+hold updates to the terminal screen before applying them to \fBcurscr\fP.
+.PP
+This is referred to as the \*(``virtual screen\*('' in the
+\fBcurs_kernel\fP(3X),
+\fBcurs_refresh\fP(3X) and
+\fBcurs_outopts\fP(3X) manual pages.
+.SS The Standard Screen
+Upon initializing curses,
+a default window called \fBstdscr\fP,
+which is the size of the terminal screen, is created.
+Many curses functions use this window.
+.SH NOTES
+The curses library is initialized using either \fBinitscr\fP(3X),
+or \fBnewterm\fP(3X).
+.PP
+If \fBcurses\fP is configured to use separate curses/terminfo libraries,
+most of these variables reside in the curses library.
+.SH PORTABILITY
+\fBTABSIZE\fP is a feature of SVr4 curses
+which is not documented by X/Open curses.
+.bP
+In SVr4 curses, \fBTABSIZE\fP is initially set from the terminal description's
+\fBinit_tabs\fP capability.
+After that, it can be altered by the applications using SVr4 curses.
+.IP
+SVr4 curses uses the current value of \fBTABSIZE\fP to
+compute the position of tabstops for updating both
+the virtual screen with \fBaddch\fP(3X) as well as
+the physical screen with \fBmvcur\fP(3X).
+.bP
+This implementation uses the current value of \fBTABSIZE\fP only for
+updating the virtual screen.
+It uses the terminal description's \fBit\fP (\fBinit_tabs\fP) capability for
+computing hardware tabs (i.e., tab stops on the physical screen).
+.bP
+Other implementations differ.
+For instance, NetBSD curses allows \fBTABSIZE\fP to be set through
+an environment variable.
+This implementation does not.
+.IP
+NetBSD curses does not support hardware tabs;
+it uses the \fBinit_tabs\fP capability and the \fBTABSIZE\fP variable
+only for updating the virtual screen.
+.PP
+\fBESCDELAY\fP is an extension in AIX curses:
+.bP
+In AIX, the units for \fBESCDELAY\fP are \fIfifths\fP of a millisecond.
+.bP
+The default value for AIX's \fBESCDELAY\fP is 0.1 seconds.
+.bP
+AIX also enforces a limit of 10,000 seconds for \fBESCDELAY\fP;
+this implementation currently has no upper limit.
+.PP
+This implementation has long used \fBESCDELAY\fP with units of milliseconds,
+making it impossible to be completely compatible with AIX.
+Likewise, most users have either decided to override the value,
+or rely upon its default value.

+Calling \fBnewwin\fP creates and returns a pointer to a new window with the

+A new full-screen window is created by calling \fBnewwin(0,0,0,0)\fP.
+.PP
+Regardless of the function used for creating a new window
+(e.g., \fBnewwin\fP, \fBsubwin\fP, \fBderwin\fP, \fBnewpad\fP),
+rather than a duplicate (with \fBdupwin\fP),
+all of the window modes are initialized to the default values.
+These functions set window modes after a window is created:

+.RE
+.ad
+.SS delwin
+.PP
+Calling \fBdelwin\fP deletes the named window, freeing all memory
+associated with it (it does not actually erase the window's screen
+image).
+Subwindows must be deleted before the main window can be deleted.
+.SS mvwin
+.PP
+Calling \fBmvwin\fP moves the window so that the upper left-hand
+corner is at position (\fIx\fP, \fIy\fP).
+If the move would cause the window to be off the screen,
+it is an error and the window is not moved.
+Moving subwindows is allowed, but should be avoided.
+.SS subwin
+.PP
+Calling \fBsubwin\fP creates and returns a pointer to a new window
+with the given number of lines, \fInlines\fP, and columns, \fIncols\fP.
+The window is at position (\fIbegin\fR_\fIy\fP,
+\fIbegin\fR_\fIx\fP) on the screen.
+The subwindow shares memory with the window \fIorig\fP,
+so that changes made to one window
+will affect both windows.
+When using this routine, it is necessary to call
+\fBtouchwin\fP or \fBtouchline\fP on \fIorig\fP before calling
+\fBwrefresh\fP on the subwindow.
+.SS derwin
+.PP
+Calling \fBderwin\fP is the same as calling \fBsubwin,\fP except that
+\fIbegin\fR_\fIy\fP and \fIbegin\fR_\fIx\fP are relative to the origin
+of the window \fIorig\fP rather than the screen.
+There is no difference between the subwindows and the derived windows.
+.PP
+Calling \fBmvderwin\fP moves a derived window (or subwindow)
+inside its parent window.
+The screen-relative parameters of the window are not changed.
+This routine is used to display different
+parts of the parent window at the same physical position on the
+screen.
+.SS dupwin
+.PP
+Calling \fBdupwin\fP creates an exact duplicate of the window \fIwin\fP.
+.SS wsyncup
+.PP
+Calling \fBwsyncup\fP touches all locations in ancestors of \fIwin\fP that are
+changed in \fIwin\fP.
+If \fBsyncok\fP is called with second argument
+\fBTRUE\fP then \fBwsyncup\fP is called automatically whenever there is a
+change in the window.
+.SS wsyncdown
+.PP
+The \fBwsyncdown\fP routine touches each location in \fIwin\fP that has been
+touched in any of its ancestor windows.
+This routine is called by
+\fBwrefresh\fP, so it should almost never be necessary to call it manually.
+.SS wcursyncup
+.PP
+The routine \fBwcursyncup\fP updates the current cursor position of all the
+ancestors of the window to reflect the current cursor position of the
+window.
+.SH RETURN VALUE
+Routines that return an integer return the integer \fBERR\fP upon failure and
+\fBOK\fP (SVr4 only specifies "an integer value other than \fBERR\fP") upon
+successful completion.
+.PP
+Routines that return pointers return \fBNULL\fP on error.
+.PP
+X/Open defines no error conditions.
+In this implementation
+.TP 5
+\fBdelwin\fP
+returns an error if the window pointer is null, or
+if the window is the parent of another window.
+.TP 5
+\fBderwin\fP
+returns an error if the parent window pointer is null, or
+if any of its ordinates or dimensions is negative, or
+if the resulting window does not fit inside the parent window.
+.TP 5
+\fBdupwin\fP
+returns an error if the window pointer is null.
+.IP
+This implementation also maintains a list of windows,
+and checks that the pointer passed to \fBdelwin\fP is one that
+it created, returning an error if it was not..
+.TP 5
+\fBmvderwin\fP
+returns an error
+if the window pointer is null, or
+if some part of the window would be placed off-screen.
+.TP 5
+\fBmvwin\fP
+returns an error
+if the window pointer is null, or
+if the window is really a pad, or
+if some part of the window would be placed off-screen.
+.TP 5
+\fBnewwin\fP
+will fail if either of its beginning ordinates is negative, or
+if either the number of lines or columns is negative.
+.TP 5
+\fBsyncok\fP
+returns an error
+if the window pointer is null.
+.TP 5
+\fBsubwin\fP
+returns an error if the parent window pointer is null, or
+if any of its ordinates or dimensions is negative, or
+if the resulting window does not fit inside the parent window.
+.PP
+The functions which return a window pointer
+may also fail if there is insufficient memory for its data structures.
+Any of these functions will fail if the screen has not been initialized,
+i.e., with \fBinitscr\fP or \fBnewterm\fP.
+.SH NOTES
+If many small changes are made to the window, the \fBwsyncup\fP option could
+degrade performance.
+.PP
+Note that \fBsyncok\fP may be a macro.
+.SH BUGS
+The subwindow functions (\fBsubwin\fP, \fBderwin\fP, \fBmvderwin\fP,
+\fBwsyncup\fP, \fBwsyncdown\fP, \fBwcursyncup\fP, \fBsyncok\fP) are flaky,
+incompletely implemented, and not well tested.
+.PP
+The System V curses documentation is very unclear about what \fBwsyncup\fP
+and \fBwsyncdown\fP actually do.
+It seems to imply that they are only
+supposed to touch exactly those lines that are affected by ancestor changes.
+The language here, and the behavior of the \fBcurses\fP implementation,
+is patterned on the XPG4 curses standard.
+The weaker XPG4 spec may result in slower updates.
+.SH PORTABILITY
+The XSI Curses standard, Issue 4 describes these functions.
+.PP
+X/Open Curses states regarding \fBdelwin\fP:
+.bP
+It must delete subwindows before deleting their parent.
+.bP
+If \fBdelwin\fP is asked to delete a parent window,
+it can only succeed if the curses library keeps a list of the subwindows.
+SVr4 curses kept a count of the number of subwindows rather than a list.
+It simply returned \fBERR\fP when asked to delete a subwindow.
+Solaris X/Open curses does not even make that check,
+and will delete a parent window which still has subwindows.
+.bP
+Since release 4.0 (1996), ncurses maintains a list of windows for each screen,
+to ensure that a window has no subwindows before allowing deletion.
+.bP
+NetBSD copied this feature of ncurses in 2003.
+.br
+PDCurses follows the scheme used in Solaris X/Open curses.

+\fBuse_default_colors\fP,
+\fBassume_default_colors\fP \- use terminal's default colors
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint use_default_colors(void);\fP
+.br
+\fBint assume_default_colors(int \fIfg\fB, int \fIbg\fB);\fR
+.SH DESCRIPTION
+The \fBuse_default_colors\fP and \fBassume_default_colors\fP
+functions are extensions to the curses library.
+They are used with terminals that support ISO 6429 color, or equivalent.
+These terminals allow the application to reset color to an unspecified
+default value (e.g., with SGR 39 or SGR 49).
+.PP
+Applications that paint a colored background over the whole screen
+do not take advantage of SGR 39 and SGR 49.
+Some applications are designed to work with the default background,
+using colors only for text.
+For example, there are several implementations of the \fBls\fP program
+which use colors to denote different file types or permissions.
+These \*(``color ls\*('' programs do not necessarily modify the background color,
+typically using only the \fBsetaf\fP terminfo capability to set the
+foreground color.
+Full-screen applications that use default colors can achieve similar
+visual effects.
+.PP
+The first function, \fBuse_default_colors\fP
+tells the curses library to assign terminal default
+foreground/background colors to color number \-1.
+So init_pair(x,COLOR_RED,\-1)
+will initialize pair x as red on default background
+and init_pair(x,\-1,COLOR_BLUE) will
+initialize pair x as default foreground on blue.
+.PP
+The other, \fBassume_default_colors\fP
+is a refinement which tells which colors to paint for color pair 0.
+This function recognizes a special color number \-1,
+which denotes the default terminal color.
+.PP
+The following are equivalent:
+.RS
+.br
+.I use_default_colors();
+.br
+.I assume_default_colors(\-1,\-1);
+.RE
+.PP
+These are ncurses extensions.
+For other curses implementations, color
+number \-1 does not mean anything, just as for ncurses before a
+successful call of \fBuse_default_colors\fP or \fBassume_default_colors\fP.
+.PP
+Other curses implementations do not allow an application to modify color pair 0.
+They assume that the background is COLOR_BLACK,
+but do not ensure that the color pair 0 is painted to match the
+assumption.
+If your application does not use either
+.B use_default_colors
+or
+.B assume_default_colors
+ncurses will paint a white foreground (text) with black background
+for color pair 0.
+.SH RETURN VALUE
+These functions return the integer \fBERR\fP upon failure
+and \fBOK\fP on success.
+They will fail if either the terminal does not support
+the \fBorig_pair\fP or \fBorig_colors\fP capability.
+If the \fBinitialize_pair\fP capability is not found, this causes an
+error as well.
+.SH NOTES
+Associated with this extension, the \fBinit_pair\fP function accepts
+negative arguments to specify default foreground or background colors.
+.PP
+The \fBuse_default_colors\fP function was added to support \fBded\fP.
+This is a full-screen application which uses curses to manage only part
+of the screen.
+The bottom portion of the screen, which is of adjustable
+size, is left uncolored to display the results from shell commands.
+The top portion of the screen colors filenames using a scheme like the
+\*(``color ls\*('' programs.
+Attempting to manage the background color of the screen for this application
+would give unsatisfactory results for a variety of reasons.
+This extension was devised after
+noting that color xterm (and similar programs) provides a background color
+which does not necessarily correspond to any of the ANSI colors.
+While a special terminfo entry could be constructed using nine colors,
+there was no mechanism provided within curses to account for the related
+\fBorig_pair\fP and \fBback_color_erase\fP capabilities.
+.PP
+The \fBassume_default_colors\fP function was added to solve
+a different problem: support for applications which would use
+environment variables and other configuration to bypass curses'
+notion of the terminal's default colors, setting specific values.
+.SH PORTABILITY
+These routines are specific to ncurses.
+They were not supported on
+Version 7, BSD or System V implementations.
+It is recommended that
+any code depending on them be conditioned using NCURSES_VERSION.

+.SH NAME
+\fBdefine_key\fP \- define a keycode
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint define_key(const char *\fIdefinition\fB, int \fIkeycode\fB);\fR
+.SH DESCRIPTION
+This is an extension to the curses library.
+It permits an application to define keycodes with their corresponding control
+strings, so that the ncurses library will interpret them just as it would
+the predefined codes in the terminfo database.
+.PP
+If the given string is null, any existing definition for the keycode is
+removed.
+Similarly, if the given keycode is negative or zero, any existing string
+for the given definition is removed.
+.SH RETURN VALUE
+The keycode must be greater than zero, and the string non-null,
+otherwise \fBERR\fP is returned.
+\fBERR\fP may also be returned if there is insufficient memory to allocate the
+data to store the definition.
+If no error is detected, \fBOK\fP is returned.
+.SH PORTABILITY
+These routines are specific to ncurses.
+They were not supported on
+Version 7, BSD or System V implementations.
+It is recommended that
+any code depending on them be conditioned using NCURSES_VERSION.

+.SH NAME
+\fBform\fP \- curses extension for programming forms
+.SH SYNOPSIS
+\fB#include <form.h>\fP
+.br
+.SH DESCRIPTION
+The \fBform\fP library provides terminal-independent facilities for composing
+form screens on character-cell terminals.
+The library includes: field
+routines, which create and modify form fields; and form routines, which group
+fields into forms, display forms on the screen, and handle interaction with the
+user.
+.PP
+The \fBform\fP library uses the \fBcurses\fP libraries.
+To use the \fBform\fP library, link with the options
+\fB\-lform \-lcurses\fP.
+.PP
+Your program should set up the locale, e.g.,
+.sp
+     \fBsetlocale(LC_ALL, "");\fP
+.sp
+so that input/output processing will work.
+.PP
+A curses initialization routine such as \fBinitscr\fP must be called
+before using any of these functions.
+.
+.SS Current Default Values for Field Attributes
+.
+The \fBform\fP library maintains a default value for field attributes.
+You
+can get or set this default by calling the appropriate \fBset_\fP
+or retrieval
+routine with a \fBNULL\fP field pointer.
+Changing this default with a
+\fBset_\fP function affects future field creations, but does not change the
+rendering of fields already created.
+.
+.SS Routine Name Index
+.
+The following table lists each \fBform\fP routine and the name of
+the manual page on which it is described.
+Routines flagged with \*(``*\*(''
+are ncurses-specific, not present in SVr4.

+.SH RETURN VALUE
+Routines that return pointers return \fBNULL\fP on error,
+and set \fBerrno\fP to the corresponding error-code returned by functions
+returning an integer.
+Routines that return
+an integer return one of the following error codes:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_BAD_STATE
+Routine was called from an initialization or termination function.
+.TP 5
+.B E_CONNECTED
+The field is already connected to a form.
+.TP 5
+.B E_INVALID_FIELD
+Contents of a field are not valid.
+.TP 5
+.B E_NOT_CONNECTED
+No fields are connected to the form.
+.TP 5
+.B E_NOT_POSTED
+The form has not been posted.
+.TP 5
+.B E_NO_ROOM
+Form is too large for its window.
+.TP 5
+.B E_POSTED
+The form is already posted.
+.TP 5
+.B E_REQUEST_DENIED
+The form driver could not process the request.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.TP 5
+.B E_UNKNOWN_COMMAND
+The form driver code saw an unknown request code.
+.SH NOTES
+The header file \fB<form.h>\fP automatically includes the header files
+\fB<curses.h>\fP and \fB<eti.h>\fP.
+.PP
+In your library list, libform.a should be before libncurses.a; that is,
+you want to say \*(``\-lform \-lncurses\*('', not the other way around
+(which would give you a link error when using static libraries).
+.SH PORTABILITY
+These routines emulate the System V forms library.
+They were not supported on
+Version 7 or BSD versions.
+.PP
+The menu facility was documented in SVr4.2 in
+\fICharacter User Interface Programming (UNIX SVR4.2)\fP.
+.PP
+It is not part of X/Open Curses.
+.PP
+Aside from ncurses, there are few implementations:
+.bP
+systems based on SVr4 source code, e.g., Solaris.
+.bP
+NetBSD curses.
+.PP
+A few functions in this implementation are extensions added for ncurses,
+but not provided by other implementations, e.g.,
+\fBform_driver_w\fP,
+\fBunfocus_current_field\fP.
+.SH AUTHORS
+Juergen Pfeifer.

+S. Raymond.

+.SH NAME
+\fBform_driver\fP,
+\fBform_driver_w\fP \- command-processing loop of the form system
+.SH SYNOPSIS
+\fB#include <form.h>\fP
+.sp
+\fBint form_driver(FORM *\fIform\fB, int \fIc\fB);\fR
+.br
+\fBint form_driver_w(FORM *\fIform\fB, int \fIc\fB, wchar_t \fIwch\fB);\fR
+.br
+.SH DESCRIPTION
+.SS form_driver
+Once a form has been posted (displayed), you should funnel input events to it
+through \fBform_driver\fP.  This routine has three major input cases:
+.bP
+The input is a form navigation request.
+Navigation request codes are constants defined in \fB<form.h>\fP,
+which are distinct from the key- and character codes returned
+by \fBwgetch\fP(3X).
+.bP
+The input is a printable character.
+Printable characters (which must be positive, less than 256) are
+checked according to the program's locale settings.
+.bP
+The input is the KEY_MOUSE special key associated with an mouse event.
+.SS form_driver_w
+.PP
+This extension simplifies the use of the forms library using wide characters.
+The input is either a key code (a request) or a wide character
+returned by \fBget_wch\fP(3X).
+The type must be passed as well,
+to enable the library to determine whether the parameter
+is a wide character or a request.
+.SS Form-driver requests
+.PP
+The form driver requests are as follows:
+.TS
+l l
+_ _

+REQ_SPREV_FIELD	Move to the sorted previous field.
+REQ_UP_CHAR	Move up in the field.
+REQ_UP_FIELD	Move up to a field.
+REQ_VALIDATION	Validate field.
+.TE
+.PP
+If the second argument is a printable character, the driver places it
+in the current position in the current field.
+If it is one of the forms
+requests listed above, that request is executed.
+.SS Field validation
+The form library makes updates to the window associated
+with form fields rather than directly to the field buffers.
+.PP
+The form driver provides low-level control over updates to the form fields.
+The form driver also provides for validating modified fields
+to ensure that the contents
+meet whatever constraints an application may attach using \fBset_field_type\fP.
+.PP
+.PP
+You can validate a field without making any changes to it using
+\fBREQ_VALIDATION\fP.
+The form driver also validates a field in these cases:
+.bP
+a call to \fBset_current_field\fP attempts to move to a different field.
+.bP
+a call to \fBset_current_page\fP attempts to move
+to a different page of the form.
+.bP
+a request attempts to move to a different field.
+.bP
+a request attempts to move to a different page of the form.
+.PP
+In each case, the move fails if the field is invalid.
+.PP
+If the modified field is valid, the form driver copies the modified
+data from the window associated with the field
+to the field buffer.
+.SS Mouse handling
+.PP
+If the second argument is the KEY_MOUSE special key, the associated
+mouse event is translated into one of the above pre-defined requests.
+Currently only clicks in the user window (e.g., inside the form display
+area or the decoration window) are handled.
+.PP
+If you click above the display region of the form:
+.RS 3
+.TP
+a REQ_PREV_FIELD is generated for a single click,
+.TP
+a REQ_PREV_PAGE is generated for a double-click and
+.TP
+a REQ_FIRST_FIELD is generated for a triple-click.
+.RE
+.PP
+If you click below the display region of the form:
+.RS 3
+.TP
+a REQ_NEXT_FIELD is generated for a single click,
+.TP
+a REQ_NEXT_PAGE is generated for a double-click and
+.TP
+a REQ_LAST_FIELD is generated for a triple-click.
+.RE
+.PP
+If you click at an field inside the display area of the form:
+.RS 3
+.bP
+the form cursor is positioned to that field.
+.bP
+If you double-click a field,
+the form cursor is positioned to that field
+and \fBE_UNKNOWN_COMMAND\fP is returned.
+This return value makes sense,
+because a double click usually means that an field-specific action should
+be returned.
+It is exactly the purpose of this return value to signal that an
+application specific command should be executed.
+.bP
+If a translation
+into a request was done, \fBform_driver\fP returns the result of this request.
+.RE
+.PP
+If you clicked outside the user window
+or the mouse event could not be translated
+into a form request an \fBE_REQUEST_DENIED\fP is returned.
+.SS Application-defined commands
+.PP
+If the second argument is neither printable nor one of the above
+pre-defined form requests, the driver assumes it is an application-specific
+command and returns \fBE_UNKNOWN_COMMAND\fP.  Application-defined commands
+should be defined relative to \fBMAX_COMMAND\fP, the maximum value of these
+pre-defined requests.
+.SH RETURN VALUE
+\fBform_driver\fP returns one of the following error codes:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_BAD_STATE
+Routine was called from an initialization or termination function.
+.TP 5
+.B E_NOT_POSTED
+The form has not been posted.
+.TP 5
+.B E_INVALID_FIELD
+Contents of field is invalid.
+.TP 5
+.B E_NOT_CONNECTED
+No fields are connected to the form.
+.TP 5
+.B E_REQUEST_DENIED
+The form driver could not process the request.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.TP 5
+.B E_UNKNOWN_COMMAND
+The form driver code saw an unknown request code.

+\fBform_field_buffer\fP \- field buffer control
+.SH SYNOPSIS
+\fB#include <form.h>\fP
+.sp
+\fBint set_field_buffer(FIELD *\fIfield\fB, int \fIbuf\fB, const char *\fIvalue\fB);\fR

+\fBbool field_status(const FIELD *\fIfield\fB);\fR
+.sp
+\fBint set_max_field(FIELD *\fIfield\fB, int \fImax\fB);\fR
+.br
+.SH DESCRIPTION
+The function \fBset_field_buffer\fP sets the numbered buffer of the given field
+to contain a given string:
+.RS 3
+.bP
+Buffer 0 is the displayed value of the field.
+.bP
+Other numbered buffers may be allocated by applications through the \fBnbuf\fP
+argument of (see \fBform_field_new\fP(3X))
+but are not manipulated by the forms library.
+.RE
+.PP
+The function \fBfield_buffer\fP returns a pointer to
+the contents of the given numbered buffer:
+.RS 3
+.bP
+The buffer contents always have the same length,
+and are padded with trailing spaces
+as needed to ensure this length is the same.
+.bP
+The buffer may contain leading spaces, depending on how it was set.
+.bP
+The buffer contents are set with \fBset_field_buffer\fP,
+or as a side effect of any editing operations on the corresponding field.
+.bP
+Editing operations are based on the \fIwindow\fP which displays the field,
+rather than a \fIstring\fP.
+The window contains only printable characters, and is filled with blanks.
+If you want the raw data, you must write your
+own routine that copies the value out of the buffer and removes the leading
+and trailing spaces.
+.bP
+Because editing operations change the content of the buffer to
+correspond to the window, you should not rely on using buffers
+for long-term storage of form data.
+.RE
+.PP
+The function \fBset_field_status\fP sets the associated status flag of
+\fIfield\fP; \fBfield_status\fP gets the current value.
+The status flag
+is set to a nonzero value whenever the field changes.
+.PP
+The function \fBset_max_field\fP sets the maximum size for a dynamic field.
+An argument of 0 turns off any maximum size threshold for that field.
+.SH RETURN VALUE
+The \fBfield_buffer\fP function returns NULL on error.
+It sets \fBerrno\fP according to their success:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.PP
+The \fBfield_status\fP function returns \fBTRUE\fP or \fBFALSE\fP.
+.PP
+The remaining routines return one of the following:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.SH SEE ALSO
+\fBcurses\fP(3X) and related pages whose names begin \*(``form_\*('' for detailed
+descriptions of the entry points.
+.SH NOTES
+The header file \fB<form.h>\fP automatically includes the header file
+.PP
+When configured for wide characters, \fBfield_buffer\fP returns a pointer
+to temporary storage (allocated and freed by the library).
+The application should not attempt to modify the data.
+It will be freed on the next call to \fBfield_buffer\fP to return the
+same buffer.
+\fB<curses.h>\fP.
+.SH PORTABILITY
+These routines emulate the System V forms library.
+They were not supported on
+Version 7 or BSD versions.
+.PP
+The \fBset_max_field\fP function checks for an ncurses extension
+\fBO_INPUT_FIELD\fP which allows a dynamic field to shrink if the new
+limit is smaller than the current field size.

+.SH DESCRIPTION
+The function \fBnew_field\fP allocates a new field and initializes it from the
+parameters given: height, width, row of upper-left corner, column of upper-left
+corner, number off-screen rows, and number of additional working buffers.
+.PP
+The function \fBdup_field\fP duplicates a field at a new location.
+Most
+attributes (including current contents, size, validation type, buffer count,

+options, and user pointer) are copied.
+Field status and the field page bit are
+not copied.
+.PP
+The function \fBlink_field\fP acts like \fBdup_field\fP, but the new field
+shares buffers with its parent.
+Attribute data is separate.
+.PP
+The function \fBfree_field\fP de-allocates storage associated with a field.
+.SH RETURN VALUE
+The functions \fBnew_field\fP, \fBdup_field\fP, \fBlink_field\fP return
+\fBNULL\fP on error.

+.SH NAME
+\fBset_field_opts\fP,

+.SH SYNOPSIS
+\fB#include <form.h>\fP

+\fBint set_field_opts(FIELD *\fIfield\fB, Field_Options \fIopts\fB);\fR
+.br
+\fBField_Options field_opts(const FIELD *\fIfield\fB);\fR

+.br
+.SH DESCRIPTION
+The function \fBset_field_opts\fP sets all the given field's option bits (field
+option bits may be logically-OR'ed together).
+.PP
+The function \fBfield_opts_on\fP turns on the given option bits, and leaves
+others alone.
+.PP
+The function \fBfield_opts_off\fP turns off the given option bits, and leaves
+others alone.
+.PP
+The function \fBfield_opts\fP returns the field's current option bits.
+.PP
+The following standard options are defined (all are on by default):
+.TP 5
+O_ACTIVE
+The field is visited during processing.
+If this option is off, the field will
+not be reachable by navigation keys.
+Please notice that an invisible field
+appears to be inactive also.
+.TP 5
+O_AUTOSKIP
+Skip to the next field when this one fills.
+.TP 5
+O_BLANK
+The field is cleared whenever a character is entered at the first position.
+.TP 5
+O_EDIT
+The field can be edited.
+.TP 5
+O_NULLOK
+Allow a blank field.
+.TP 5
+O_PASSOK
+Validate field only if modified by user.
+.TP 5
+O_PUBLIC
+The field contents are displayed as data is entered.
+.TP 5
+O_STATIC
+Field buffers are fixed to field's original size.
+Turn this option off to create a dynamic field.
+.TP 5
+O_VISIBLE
+The field is displayed.
+If this option is off, display of the field is
+suppressed.
+.TP 5
+O_WRAP
+Words that do not fit on a line are wrapped to the next line.
+Words are
+blank-separated.
+.PP
+These extension options are defined (extensions are off by default):
+.TP 5
+O_DYNAMIC_JUSTIFY
+Permit dynamic fields to be justified, like static fields.
+.TP 5
+O_NO_LEFT_STRIP
+Preserve leading whitespace in the field buffer, which is normally discarded.
+.TP 5
+O_EDGE_INSERT_STAY
+When inserting into a field up to the boundary position,
+optionally delay the scrolling,
+so that the last inserted character remains visible,
+but advance the cursor to reflect the insertion.
+This allows the form library to display the
+inserted character in one-character fields
+as well as allowing the library to maintain consistent state.
+.TP 5
+O_INPUT_FIELD
+The \fBset_max_field\fP function checks for this extension,
+which allows a dynamic field to shrink if the new
+limit is smaller than the current field size.
+.SH RETURN VALUE
+Except for \fBfield_opts\fP, each routine returns one of the following:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_CURRENT
+The field is the current field.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).

+.SH DESCRIPTION
+By default, no validation is done on form fields.
+You can associate a form with with a \fIfield type\fP,
+making the form library validate input.
+.SS field_arg
+Returns a pointer to the field's argument block.
+The \fIargument block\fP is an opaque structure containing
+a copy of the arguments provided in a \fBset_field_type\fP call.
+.SS field_type
+Returns a pointer to the \fIfield type\fP associated with the form field,
+i.e., by calling \fBset_field_type\fP.
+.SS set_field_type
+The function \fBset_field_type\fP associates
+a field type with a given form field.
+This is the type checked by validation functions.
+Most field types are configurable,
+via arguments which the caller provides when calling \fBset_field_type\fP.
+.PP
+Several field types are predefined by the form library.
+.SS Predefined types
+.PP
+It is possible to set up new programmer-defined field types.
+Field types are implemented via the \fBFIELDTYPE\fP data
+structure, which contains several pointers to functions.
+.PP
+See the \fBform_fieldtype\fP(3X) manual page,
+which describes functions which can be used to construct
+a field-type dynamically.
+.PP
+The predefined types are as follows:
+.TP 5
+TYPE_ALNUM
+Alphanumeric data.
+Required parameter:
+.RS
+.bP
+a third \fBint\fP argument, a minimum field width.
+.RE
+.TP 5
+TYPE_ALPHA
+Character data.
+Required parameter:
+.RS
+.bP
+a third \fBint\fP argument, a minimum field width.
+.RE
+.TP 5
+TYPE_ENUM
+Accept one of a specified set of strings.
+Required parameters:
+.RS
+.bP
+a third \fB(char **)\fP argument pointing to a string list;
+.bP
+a fourth \fBint\fP flag argument to enable case-sensitivity;
+.bP
+a fifth \fBint\fP flag argument specifying whether a partial
+match must be a unique one.
+If this flag is off, a prefix matches the first
+of any set of more than one list elements with that prefix.
+.RE
+.IP
+The library copies the string list,
+so you may use a list that lives in automatic variables on the stack.
+.TP 5
+TYPE_INTEGER
+Integer data, parsable to an integer by \fBatoi\fP(3).
+Required parameters:
+.RS
+.bP
+a third \fBint\fP argument controlling the precision,
+.bP
+a fourth \fBlong\fP argument constraining minimum value,
+.bP
+a fifth \fBlong\fP constraining maximum value.
+If the maximum value is less than or equal to the minimum value, the range is
+simply ignored.
+.RE
+.IP
+On return, the field buffer is formatted according to the
+\fBprintf\fP format specification \*(``.*ld\*('',
+where the \*(``*\*('' is replaced by the precision argument.
+.IP
+For details of the precision handling see \fBprintf\fP(3).
+.TP 5
+TYPE_NUMERIC
+Numeric data (may have a decimal-point part).
+Required parameters:
+.RS
+.bP
+a third \fBint\fP argument controlling the precision,
+.bP
+a fourth \fBdouble\fP argument constraining minimum value,
+.bP
+and a fifth \fBdouble\fP constraining maximum value.
+If your system supports locales,
+the decimal point character must be the one specified by your locale.
+If the maximum value is less than or equal to the minimum value,
+the range is simply ignored.
+.RE
+.IP
+On return, the field buffer is formatted according to the
+\fBprintf\fP format specification \*(``.*f\*('',
+where the \*(``*\*('' is replaced by the precision argument.
+.IP
+For details of the precision handling see \fBprintf\fP(3).
+.TP 5
+TYPE_REGEXP
+Regular expression data.
+Required parameter:
+.RS
+.bP
+a third argument, a regular expression \fB(char *)\fP string.
+The data is valid if the regular expression matches it.
+.RE
+.IP
+Regular expressions
+are in the format of \fBregcomp\fP and \fBregexec\fP.
+.IP
+The regular expression must match the whole field.
+If you have for example, an eight character wide field,
+a regular expression "^[0\-9]*$" always
+means that you have to fill all eight positions with digits.
+If you want to allow fewer digits,
+you may use for example "^[0\-9]* *$" which is good for
+trailing spaces (up to an empty field),
+or "^ *[0\-9]* *$" which is good for
+leading and trailing spaces around the digits.
+.TP 5
+TYPE_IPV4
+An Internet Protocol Version 4 address.
+Required parameter:
+.RS
+.bP
+none
+.RE
+.IP
+The form library checks whether or not the buffer has the form \fIa.b.c.d\fP,
+where \fIa\fP, \fIb\fP, \fIc\fP, and \fId\fP are numbers in the range 0 to 255.
+Trailing blanks in the buffer are ignored.
+The address itself is not validated.
+.IP
+This is an ncurses extension;
+this field type may not be available in other curses implementations.
+.SH RETURN VALUE
+The functions \fBfield_type\fP and \fBfield_arg\fP return \fBNULL\fP on error.
+The function \fBset_field_type\fP returns one of the following:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).

+.SH DESCRIPTION
+.SS new_fieldtype
+The function \fBnew_fieldtype\fP creates a new field type usable for data
+validation.
+Its parameters are function pointers:
+.TP 5
+\fIfield_check\fP
+This function checks the
+validity of an entered data string whenever the user attempts to leave a field.
+It has two arguments:
+.RS
+.bP
+The (FIELD *) argument is passed in so the validation predicate can see the
+field's buffer, sizes and other attributes.
+.bP
+The second argument is an
+argument-block structure, about which more below.
+.RE
+.TP 5
+\fIchar_check\fP
+This function validates input characters as they are entered.
+The form library passes it the character to be checked
+and a pointer to an argument-block structure.
+.SS free_fieldtype
+.PP
+The \fBfree_fieldtype\fP function
+frees the space allocated for a given validation type by \fBnew_fieldtype\fP.
+.SS set_fieldtype_arg
+.PP
+The function \fBset_fieldtype_arg\fP associates
+three storage-management functions with a field type:
+.TP 5
+\fImake_arg\fP
+This function is automatically applied to the
+list of arguments you give \fBset_field_type\fP when attaching validation
+to a field.
+It stores the arguments in an allocated argument-block
+object which is used when validating input.
+.TP 5
+\fIcopy_arg\fP
+This function may be used by applications to copy argument-blocks.
+.TP 5
+\fIfree_arg\fP
+Frees an argument-block structure.
+.PP
+You must supply the \fImake_arg\fP function.
+The other two are optional: you may supply NULL for them.
+In this case, the form library assumes
+that \fImake_arg\fP does not allocate memory but simply loads the
+argument into a single scalar value.
+.SS set_fieldtype_choice
+.PP
+The form driver requests \fBREQ_NEXT_CHOICE\fP and \fBREQ_PREV_CHOICE\fP assume
+that the possible values of a field form an ordered set, and provide the forms
+user with a way to move through the set.
+.PP
+The \fBset_fieldtype_choice\fP
+function allows forms programmers to define successor and predecessor functions
+for the field type.
+These functions take the field pointer and an
+argument-block structure as arguments.
+.SS link_fieldtype
+.PP
+The function \fBlink_fieldtype\fP creates
+a new field type from the two given types.
+They are connected by an logical 'OR'.
+.SH RETURN VALUE
+The pointer-valued routines return NULL on error.
+They set \fBerrno\fP according to their success:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred, e.g., malloc failure.
+.PP
+The integer-valued routines return one of the following codes on
+error:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_CONNECTED
+The field is already connected to a form.

+The function \fBset_field_term\fP sets a hook to be called at form-unpost time
+and each time the selected field changes (before the change).
+\fBfield_term\fP
+returns the current field term hook, if any (\fBNULL\fP if there is no such
+hook).
+.PP
+The function \fBset_form_init\fP sets a hook to be called at form-post time and
+just after a page change once it is posted.
+\fBform_init\fP returns the
+current form init hook, if any (\fBNULL\fP if there is no such hook).
+.PP
+The function \fBset_form_term\fP sets a hook to be called at form-unpost time
+and just before a page change once it is posted.
+\fBform_init\fP
+returns the current form term hook, if any (\fBNULL\fP if there is no such

+.br
+.SH DESCRIPTION
+The function \fBset_current_field\fP sets the current field of the given
+form; \fBcurrent_field\fP returns the current field of the given form.
+.PP
+The function \fBunfocus_current_field\fP removes the focus from the current
+field of the form.
+In such state, inquiries via \fBcurrent_field\fP shall return a NULL pointer.
+.PP
+The function \fBset_form_page\fP sets the form's page number (goes to page
+\fIn\fP of the form).
+.PP
+The function \fBform_page\fP returns the form's current page number.
+.PP
+The function \fBfield_index\fP returns the index of the field in the
+field array of the form it is connected to.
+It returns \fBERR\fP if
+the argument is the null pointer or the field is not connected.
+.SH RETURN VALUE
+Except for \fBform_page\fP, each routine returns one of the following:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_BAD_STATE
+Routine was called from an initialization or termination function.
+.TP 5
+.B E_INVALID_FIELD
+Contents of a field are not valid.
+.TP 5
+.B E_REQUEST_DENIED
+The form driver could not process the request.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.
+.SH SEE ALSO
+\fBcurses\fP(3X), \fBform\fP(3X).

+These routines emulate the System V forms library.
+They were not supported on
+Version 7 or BSD versions.
+.PP
+The \fBunfocus_current_field\fP function is an ncurses extension.

+.SH NAME
+\fBform_win\fP \- make and break form window and subwindow associations
+.SH SYNOPSIS
+\fB#include <form.h>\fP
+.sp
+\fBint set_form_win(FORM *\fIform\fB, WINDOW *\fIwin\fB);\fR
+.br
+\fBWINDOW *form_win(const FORM *\fIform\fB);\fR
+.sp
+\fBint set_form_sub(FORM *\fIform\fB, WINDOW *\fIsub\fB);\fR
+.br
+\fBWINDOW *form_sub(const FORM *\fIform\fB);\fR
+.sp
+\fBint scale_form(const FORM *\fIform\fB, int *\fIrows\fB, int *\fIcolumns\fB);\fR
+.br
+.SH DESCRIPTION
+Every form has an associated pair of \fBcurses\fP windows.
+The form window
+displays any title and border associated with the window; the form subwindow
+displays the items of the form that are currently available for selection.
+.PP
+The first four functions get and set those windows.
+It is not necessary to set
+either window; by default, the driver code uses \fBstdscr\fP for both.
+.PP
+In the \fBset_\fP functions, window argument of \fBNULL\fP is treated as though
+it were \fBstsdcr\fP.  A form argument of \fBNULL\fP is treated as a request
+to change the system default form window or subwindow.
+.PP
+The function \fBscale_form\fP returns the minimum size required for the
+subwindow of \fIform\fP.
+.SH RETURN VALUE
+Routines that return pointers return \fBNULL\fP on error.
+Routines that return
+an integer return one of the following error codes:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_POSTED
+The form has already been posted.
+.TP 5
+.B E_NOT_CONNECTED
+No items are connected to the form.
+.SH SEE ALSO

+.SH NOTES
+The header file \fB<form.h>\fP automatically includes the header file
+\fB<curses.h>\fP.
+.SH PORTABILITY
+These routines emulate the System V forms library.
+They were not supported on
+Version 7 or BSD versions.

+.SH DESCRIPTION
+\fB@INFOCMP@\fP can be used to compare a binary \fBterminfo\fP entry with other
+terminfo entries, rewrite a \fBterminfo\fP description to take advantage of the
+\fBuse=\fP terminfo field, or print out a \fBterminfo\fP description from the
+binary file (\fBterm\fP) in a variety of formats.
+In all cases, the boolean
+fields will be printed first, followed by the numeric fields, followed by the
+string fields.
+.SS Default Options
+If no options are specified and zero or one \fItermnames\fP are specified, the
+\fB\-I\fP option will be assumed.
+If more than one \fItermname\fP is specified,
+the \fB\-d\fP option will be assumed.
+.SS Comparison Options [\-d] [\-c] [\-n]
+\fB@INFOCMP@\fP compares the \fBterminfo\fP description of the first terminal
+\fItermname\fP with each of the descriptions given by the entries for the other
+terminal's \fItermnames\fP.
+If a capability is defined for only one of the
+terminals, the value returned depends on the type of the capability:
+.bP
+\fBF\fP for missing boolean variables
+.bP
+\fBNULL\fP for missing integer or string variables
+.PP
+Use the \fB\-q\fP option to show the distinction between
+\fIabsent\fP and \fIcancelled\fP capabilities.
+.PP
+These options produce a list which you can use to compare two
+or more terminal descriptions:
+.TP 5
+\fB\-d\fP
+produces a list of each capability that is \fIdifferent\fP
+between two entries.
+Each item in the list shows \*(``:\*('' after the capability name,
+followed by the capability values, separated by a comma.
+.TP
+\fB\-c\fP
+produces a list of each capability that is \fIcommon\fP between
+two or more entries.
+Missing capabilities are ignored.
+Each item in the list shows \*(``=\*('' after the capability name,
+followed by the capability value.
+.IP
+The \fB\-u\fP option provides a related output,
+showing the first terminal description rewritten to use the second
+as a building block via the \*(``use=\*('' clause.
+.TP
+\fB\-n\fP
+produces a list of each capability that is in \fInone\fP of the given entries.
+Each item in the list shows \*(``!\*('' before the capability name.
+.IP
+Normally only the conventional capabilities are shown.
+Use the \fB\-x\fP option to add the BSD-compatibility
+capabilities (names prefixed with \*(``OT\*('').
+.IP
+If no \fItermnames\fP are given,
+\fB@INFOCMP@\fP uses the environment variable \fBTERM\fP
+for each of the \fItermnames\fP.
+.SS Source Listing Options [\-I] [\-L] [\-C] [\-r]
+The \fB\-I\fP, \fB\-L\fP, and \fB\-C\fP options will produce
+a source listing for each terminal named.
+.
+.TS
+center tab(/) ;
+l l .
+\fB\-I\fP/use the \fBterminfo\fP names
+\fB\-L\fP/use the long C variable name listed in <\fBterm.h\fP>
+\fB\-C\fP/use the \fBtermcap\fP names
+\fB\-r\fP/when using \fB\-C\fP, put out all capabilities in \fBtermcap\fP form
+\fB\-K\fP/modifies the \fB\-C\fP option, improving BSD-compatibility.
+.TE
+.PP
+If no \fItermnames\fP are given, the environment variable \fBTERM\fP will be
+used for the terminal name.
+.PP
+The source produced by the \fB\-C\fP option may be used directly as a
+\fBtermcap\fP entry, but not all parameterized strings can be changed to
+the \fBtermcap\fP format.
+\fB@INFOCMP@\fP will attempt to convert most of the
+parameterized information, and anything not converted will be plainly marked in
+the output and commented out.
+These should be edited by hand.
+.PP
+For best results when converting to \fBtermcap\fP format,
+you should use both \fB\-C\fP and \fB\-r\fP.
+Normally a termcap description is limited to 1023 bytes.
+\fB@INFOCMP@\fP trims away less essential parts to make it fit.
+If you are converting to one of the (rare) termcap implementations
+which accept an unlimited size of termcap,
+you may want to add the \fB\-T\fP option.
+More often however, you must help the termcap implementation,
+and trim excess whitespace (use the \fB\-0\fP option for that).
+.PP
+All padding information for strings will be collected together and placed
+at the beginning of the string where \fBtermcap\fP expects it.
+Mandatory
+padding (padding information with a trailing \*(``/\*('') will become optional.
+.PP
+All \fBtermcap\fP variables no longer supported by \fBterminfo\fP, but which
+are derivable from other \fBterminfo\fP variables, will be output.
+Not all
+\fBterminfo\fP capabilities will be translated; only those variables which were
+part of \fBtermcap\fP will normally be output.
+Specifying the \fB\-r\fP option
+will take off this restriction, allowing all capabilities to be output in
+\fItermcap\fP form.
+Normally you would use both the \fB\-C\fP and \fB\-r\fP options.
+The actual format used incorporates some improvements for escaped characters
+from terminfo format.
+For a stricter BSD-compatible translation, use the \fB\-K\fP option
+rather than \fB\-C\fP.
+.PP
+Note that because padding is collected to the beginning of the capability, not
+all capabilities are output.
+Mandatory padding is not supported.
+Because
+\fBtermcap\fP strings are not as flexible, it is not always possible to convert
+a \fBterminfo\fP string capability into an equivalent \fBtermcap\fP format.
+A subsequent conversion of the \fBtermcap\fP file
+back into \fBterminfo\fP format
+will not necessarily reproduce the original \fBterminfo\fP source.
+.PP
+Some common \fBterminfo\fP parameter sequences, their \fBtermcap\fP
+equivalents, and some terminal types which commonly have such sequences, are:

+.TE
+.SS Use= Option [\-u]
+The \fB\-u\fP option produces a \fBterminfo\fP source description of the first
+terminal \fItermname\fP which is relative to the sum of the descriptions given
+by the entries for the other terminals \fItermnames\fP.
+It does this by
+analyzing the differences between the first \fItermname\fP and the other
+\fItermnames\fP and producing a description with \fBuse=\fP fields for the
+other terminals.
+In this manner, it is possible to retrofit generic terminfo
+entries into a terminal's description.
+Or, if two similar terminals exist, but
+were coded at different times or by different people so that each description
+is a full description, using \fB@INFOCMP@\fP
+will show what can be done to change
+one description to be relative to the other.
+.PP
+A capability will be printed with an at-sign (@) if it no longer exists in the
+first \fItermname\fP, but one of the other \fItermname\fP entries contains a
+value for it.
+A capability's value will be printed if the value in the first
+\fItermname\fP is not found in any of the other \fItermname\fP entries, or if
+the first of the other \fItermname\fP entries that has this capability gives a
+different value for the capability than that in the first \fItermname\fP.
+.PP
+The order of the other \fItermname\fP entries is significant.
+Since the
+terminfo compiler \fB@TIC@\fP does a left-to-right scan of the capabilities,
+specifying two \fBuse=\fP entries that contain differing entries for the same
+capabilities will produce different results depending on the order that the
+entries are given in.
+\fB@INFOCMP@\fP will flag any such inconsistencies between
+the other \fItermname\fP entries as they are found.
+.PP
+Alternatively, specifying a capability \fIafter\fP a \fBuse=\fP entry that
+contains that capability will cause the second specification to be ignored.
+Using \fB@INFOCMP@\fP to recreate a description can be a useful check to make
+sure that everything was specified correctly in the original source
+description.
+.PP
+Another error that does not cause incorrect compiled files, but will slow down
+the compilation time, is specifying extra \fBuse=\fP fields that are
+superfluous.
+\fB@INFOCMP@\fP will flag any other \fItermname use=\fP fields that
+were not needed.
+.SS Changing Databases [\-A \fIdirectory\fR] [\-B \fIdirectory\fR]
+Like other \fBncurses\fP utilities,
+\fB@INFOCMP@\fP looks for the terminal descriptions in several places.
+You can use the \fBTERMINFO\fP and \fBTERMINFO_DIRS\fP environment variables
+to override the compiled-in default list of places to search
+(see \fBcurses\fP(3X) for details).
+.PP
+You can also use the options \fB\-A\fP
+and \fB\-B\fP to override the list of places to search
+when comparing terminal descriptions:
+.bP
+The \fB\-A\fP option sets the location for the first \fItermname\fP
+.bP
+The \fB\-B\fP option sets the location for the other \fItermnames\fP.
+.PP
+Using these options, it is possible to
+compare descriptions for a terminal with the same name located in two different
+databases.
+For instance,
+you can use this feature for comparing descriptions for the same terminal
+created by different people.
+.SS Other Options
+.TP 5
+\fB\-0\fP
+causes the fields to be printed on one line, without wrapping.
+.TP 5
+\fB\-1\fP
+causes the fields to be printed out one to a line.
+Otherwise,
+the fields will be printed several to a line to a maximum width
+of 60 characters.
+.TP
+\fB\-a\fP
+tells \fB@INFOCMP@\fP to retain commented-out capabilities
+rather than discarding them.
+Capabilities are commented by prefixing them with a period.
+.TP
+\fB\-D\fP
+tells \fB@INFOCMP@\fP to print the database locations that it knows about,
+and exit.
+.TP 5
+\fB\-E\fP
+Dump the capabilities of the given terminal as tables, needed in
+the C initializer for a
+TERMTYPE structure (the terminal capability structure in the \fB<term.h>\fP).
+This option is useful for preparing versions of the curses library hardwired
+for a given terminal type.
+The tables are all declared static, and are named according to the type
+and the name of the corresponding terminal entry.
+.sp
+Before ncurses 5.0, the split between the \fB\-e\fP and \fB\-E\fP
+options was not needed; but support for extended names required making
+the arrays of terminal capabilities separate from the TERMTYPE structure.
+.TP 5
+\fB\-e\fP
+Dump the capabilities of the given terminal as a C initializer for a
+TERMTYPE structure (the terminal capability structure in the \fB<term.h>\fP).
+This option is useful for preparing versions of the curses library hardwired
+for a given terminal type.
+.TP 5
+\fB\-F\fP
+compare terminfo files.
+This assumes that two following arguments are filenames.
+The files are searched for pairwise matches between
+entries, with two entries considered to match if any of their names do.
+The report printed to standard output lists entries with no matches in
+the other file, and entries with more than one match.
+For entries
+with exactly one match it includes a difference report.
+Normally,
+to reduce the volume of the report, use references are
+not resolved before looking for differences, but resolution can be forced
+by also specifying \fB\-r\fP.
+.TP 5
+\fB\-f\fP
+Display complex terminfo strings which contain if/then/else/endif expressions
+indented for readability.
+.TP 5
+\fB\-G\fP
+Display constant literals in decimal form
+rather than their character equivalents.
+.TP 5
+\fB\-g\fP
+Display constant character literals in quoted form
+rather than their decimal equivalents.
+.TP 5
+\fB\-i\fP
+Analyze the initialization (\fBis1\fP, \fBis2\fP, \fBis3\fP), and reset
+(\fBrs1\fP, \fBrs2\fP, \fBrs3\fP), strings in the entry,
+as well as those used for starting/stopping cursor-positioning mode
+(\fBsmcup\fP, \fBrmcup\fP) as well as starting/stopping keymap mode
+(\fBsmkx\fP, \fBrmkx\fP).
+.IP
+For each string, the
+code tries to analyze it into actions in terms of the other capabilities in the
+entry, certain X3.64/ISO 6429/ECMA\-48 capabilities, and certain DEC VT-series
+private modes (the set of recognized special sequences has been selected for
+completeness over the existing terminfo database).
+Each report line consists
+of the capability name, followed by a colon and space, followed by a printable
+expansion of the capability string with sections matching recognized actions
+translated into {}-bracketed descriptions.

+.TP 5
+\fB\-T\fP

+\fB\-U\fP
+tells \fB@INFOCMP@\fP to not post-process the data

+Compiled terminal description database.
+.SH HISTORY
+Although System V Release 2 provided a terminfo library,
+it had no documented tool for decompiling the terminal descriptions.
+Tony Hansen (AT&T) wrote the first \fBinfocmp\fP in early 1984,
+for System V Release 3.
+.PP
+Eric Raymond used the AT&T documentation in 1995 to provide an equivalent
+\fB@INFOCMP@\fP for ncurses.
+In addition, he added a few new features such as:
+.bP
+the \fB\-e\fP option, to support \fIfallback\fP
+(compiled-in) terminal descriptions
+.bP
+the \fB\-i\fP option, to help with analysis
+.PP
+Later, Thomas Dickey added the \fB\-x\fP (user-defined capabilities)
+option, and the \fB\-E\fP option to support fallback entries with
+user-defined capabilities.
+.PP
+For a complete list, see the \fIEXTENSIONS\fP section.
+.PP
+In 2010, Roy Marples provided an \fBinfocmp\fP program for NetBSD.
+It is less capable than the SVr4 or ncurses versions
+(e.g., it lacks the sorting options documented in X/Open),
+but does include the \fB\-x\fP option adapted from ncurses.
+.SH PORTABILITY
+X/Open Curses, Issue 7 (2009) provides a description of \fBinfocmp\fP.
+It does not mention the options used for converting to termcap format.
+.SH EXTENSIONS
+The
+\fB\-0\fP,
+\fB\-1\fP,
+\fB\-E\fP,
+\fB\-F\fP,
+\fB\-G\fP,
+\fB\-Q\fP,
+\fB\-R\fP,
+\fB\-T\fP,
+\fB\-V\fP,
+\fB\-a\fP,
+\fB\-e\fP,
+\fB\-f\fP,
+\fB\-g\fP,
+\fB\-i\fP,
+\fB\-l\fP,
+\fB\-p\fP,
+\fB\-q\fP and
+\fB\-t\fP
+options are not supported in SVr4 curses.
+.PP
+SVr4 infocmp does not distinguish between absent and cancelled capabilities.
+Also, it shows missing integer capabilities as \fB\-1\fP
+(the internal value used to represent missing integers).
+This implementation shows those as \*(``NULL\*('',
+for consistency with missing strings.
+.PP
+The \fB\-r\fP option's notion of \*(``termcap\*('' capabilities
+is System V Release 4's.
+Actual BSD curses versions will have a more restricted set.
+To see only the
+4.4BSD set, use \fB\-r\fP \fB\-RBSD\fP.
+.SH BUGS
+The \fB\-F\fP option of \fB@INFOCMP@\fP(1M) should be a \fB@TOE@\fP(1M) mode.

+.SH NAME
+\fBuse_legacy_coding\fP \- override locale-encoding checks
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint use_legacy_coding(int \fIlevel\fB);\fR
+.SH DESCRIPTION
+The \fBuse_legacy_coding\fP function is an extension to the curses library.
+It allows the caller to change the result of \fBunctrl\fP,
+and suppress related checks within the library that would normally
+cause nonprinting characters to be rendered in visible form.
+This affects only 8-bit characters.
+.PP
+The \fIlevel\fP parameter controls the result:
+.RS
+.TP 5
+0
+the library functions normally,
+rendering nonprinting characters as described in \fBunctrl\fP.
+.TP
+1
+the library ignores \fBisprintf\fP for codes in the range 160-255.
+.TP
+2
+the library ignores \fBisprintf\fP for codes in the range 128-255.
+It also modifies the output of \fBunctrl\fP, showing codes in the
+range 128-159 as is.
+.RE
+.SH RETURN VALUE
+If the screen has not been initialized,
+or the \fIlevel\fP parameter is out of range,
+the function returns \fBERR\fP.
+Otherwise, it returns the previous level: \fB0\fP, \fB1\fP or \fB2\fP.
+.SH PORTABILITY
+This routine is specific to ncurses.
+It was not supported on Version 7, BSD or System V implementations.
+It is recommended that any code depending on ncurses extensions
+be conditioned using NCURSES_VERSION.
+.SH SEE ALSO
+\fBunctrl\fP(3X).
+.SH AUTHOR
+Thomas Dickey (to support lynx's font-switching feature).

+.SH NAME
+\fBmenu\fP \- curses extension for programming menus
+.SH SYNOPSIS
+\fB#include <menu.h>\fP
+.br
+.SH DESCRIPTION
+The \fBmenu\fP library provides terminal-independent facilities for composing
+menu systems on character-cell terminals.
+The library includes: item routines,
+which create and modify menu items; and menu routines, which group items into
+menus, display menus on the screen, and handle interaction with the user.
+.PP
+The \fBmenu\fP library uses the \fBcurses\fP libraries, and a curses
+initialization routine such as \fBinitscr\fP must be called before using any of
+these functions.
+To use the \fBmenu\fP library, link with the options
+\fB\-lmenu \-lcurses\fP.
+.
+.SS Current Default Values for Item Attributes
+.
+The \fBmenu\fP library maintains a default value for item attributes.
+You can
+get or set this default by calling the appropriate \fBget_\fP or \fBset_\fP
+routine with a \fBNULL\fP item pointer.
+Changing this default with a
+\fBset_\fP function affects future item creations, but does not change the
+rendering of items already created.
+.
+.SS Routine Name Index
+.
+The following table lists each \fBmenu\fP routine and the name of
+the manual page on which it is described.

+.SH RETURN VALUE
+Routines that return pointers return \fBNULL\fP on error.
+Routines that return
+an integer return one of the following error codes:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_BAD_STATE
+Routine was called from an initialization or termination function.
+.TP 5
+.B E_NO_MATCH
+Character failed to match.
+.TP 5
+.B E_NO_ROOM
+Menu is too large for its window.
+.TP 5
+.B E_NOT_CONNECTED
+No items are connected to the menu.
+.TP 5
+.B E_NOT_POSTED
+The menu has not been posted.
+.TP 5
+.B E_NOT_SELECTABLE
+The designated item cannot be selected.
+.TP 5
+.B E_POSTED
+The menu is already posted.
+.TP 5
+.B E_REQUEST_DENIED
+The menu driver could not process the request.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.TP 5
+.B E_UNKNOWN_COMMAND
+The menu driver code saw an unknown request code.
+.SH NOTES
+The header file \fB<menu.h>\fP automatically includes the header files
+\fB<curses.h>\fP and \fB<eti.h>\fP.
+.PP
+In your library list, libmenu.a should be before libncurses.a; that is,
+you should say \*(``\-lmenu \-lncurses\*('', not the other way around
+(which would give a link-error when using static libraries).
+.SH PORTABILITY
+These routines emulate the System V menu library.
+They were not supported on
+Version 7 or BSD versions.
+.PP
+The menu facility was documented in SVr4.2 in
+\fICharacter User Interface Programming (UNIX SVR4.2)\fP.
+.PP
+It is not part of X/Open Curses.
+.PP
+Aside from ncurses, there are few implementations:
+.bP
+systems based on SVr4 source code, e.g., Solaris.
+.bP
+NetBSD curses.
+.SH AUTHORS
+Juergen Pfeifer.
+Manual pages and adaptation for ncurses by Eric S. Raymond.
+.SH SEE ALSO
+\fBcurses\fP(3X) and related pages whose names begin \*(``menu_\*(''
+for detailed descriptions of the entry points.

+.SH NAME
+\fBmenu_driver\fP \- command-processing loop of the menu system
+.SH SYNOPSIS
+\fB#include <menu.h>\fP
+.sp
+\fBint menu_driver(MENU *\fImenu\fB, int \fIc\fB);\fR
+.br
+.SH DESCRIPTION
+Once a menu has been posted (displayed), you should funnel input events to it
+through \fBmenu_driver\fP.  This routine has three major input cases:
+.bP
+The input is a form navigation request.
+Navigation request codes are constants defined in \fB<form.h>\fP,
+which are distinct from the key- and character codes
+returned by \fBwgetch\fP(3X).
+.bP
+The input is a printable character.
+Printable characters (which must be positive, less than 256) are
+checked according to the program's locale settings.
+.bP
+The input is the KEY_MOUSE special key associated with an mouse event.
+.PP
+The menu driver requests are as follows:
+.TP 5
+REQ_LEFT_ITEM
+Move left to an item.
+.TP 5
+REQ_RIGHT_ITEM
+Move right to an item.
+.TP 5
+REQ_UP_ITEM
+Move up to an item.
+.TP 5
+REQ_DOWN_ITEM
+Move down to an item.
+.TP 5
+REQ_SCR_ULINE
+Scroll up a line.
+.TP 5
+REQ_SCR_DLINE
+Scroll down a line.
+.TP 5
+REQ_SCR_DPAGE
+Scroll down a page.
+.TP 5
+REQ_SCR_UPAGE
+Scroll up a page.
+.TP 5
+REQ_FIRST_ITEM
+Move to the first item.
+.TP 5
+REQ_LAST_ITEM
+Move to the last item.
+.TP 5
+REQ_NEXT_ITEM
+Move to the next item.
+.TP 5
+REQ_PREV_ITEM
+Move to the previous item.
+.TP 5
+REQ_TOGGLE_ITEM
+Select/deselect an item.
+.TP 5
+REQ_CLEAR_PATTERN
+Clear the menu pattern buffer.
+.TP 5
+REQ_BACK_PATTERN
+Delete the previous character from the pattern buffer.
+.TP 5
+REQ_NEXT_MATCH
+Move to the next item matching the pattern match.
+.TP 5
+REQ_PREV_MATCH
+Move to the previous item matching the pattern match.
+.PP
+If the second argument is a printable character, the code appends
+it to the pattern buffer and attempts to move to the next item matching
+the new pattern.
+If there is no such match, \fBmenu_driver\fP returns
+\fBE_NO_MATCH\fP and deletes the appended character from the buffer.
+.PP
+If the second argument is one of the above pre-defined requests, the
+corresponding action is performed.
+.SS MOUSE HANDLING
+.PP
+If the second argument is the KEY_MOUSE special key, the associated
+mouse event is translated into one of the above pre-defined requests.
+Currently only clicks in the user window (e.g., inside the menu display
+area or the decoration window) are handled.
+.PP
+If you click above the display region of the menu:
+.bP
+a REQ_SCR_ULINE is generated for a single click,
+.bP
+a REQ_SCR_UPAGE is generated for a double-click and
+.bP
+a REQ_FIRST_ITEM is generated for a triple-click.
+.PP
+If you click below the display region of the menu:
+.bP
+a REQ_SCR_DLINE is generated for a single click,
+.bP
+a REQ_SCR_DPAGE is generated for a double-click and
+.bP
+a REQ_LAST_ITEM is generated for a triple-click.
+.PP
+If you click at an item inside the display area of the menu:
+.bP
+the menu cursor is positioned to that item.
+.bP
+If you double-click an item a REQ_TOGGLE_ITEM
+is generated and \fBE_UNKNOWN_COMMAND\fP is returned.
+This return value makes sense,
+because a double click usually means that an item-specific action should
+be returned.
+It is exactly the purpose of this return value to signal that an
+application specific command should be executed.
+.bP
+If a translation
+into a request was done, \fBmenu_driver\fP returns the result of this request.
+.PP
+If you clicked outside the user window
+or the mouse event could not be translated
+into a menu request an \fBE_REQUEST_DENIED\fP is returned.
+.SS APPLICATION-DEFINED COMMANDS
+.PP
+If the second argument is neither printable nor one of the above
+pre-defined menu requests or KEY_MOUSE,
+the drive assumes it is an application-specific
+command and returns \fBE_UNKNOWN_COMMAND\fP.  Application-defined commands
+should be defined relative to \fBMAX_COMMAND\fP, the maximum value of these
+pre-defined requests.
+.SH RETURN VALUE
+\fBmenu_driver\fP return one of the following error codes:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_BAD_STATE
+Routine was called from an initialization or termination function.
+.TP 5
+.B E_NOT_POSTED
+The menu has not been posted.
+.TP 5
+.B E_UNKNOWN_COMMAND
+The menu driver code saw an unknown request code.
+.TP 5
+.B E_NO_MATCH
+Character failed to match.
+.TP 5
+.B E_REQUEST_DENIED
+The menu driver could not process the request.

+.SH DESCRIPTION
+These functions make it possible to set hook functions to be called at various
+points in the automatic processing of input event codes by \fBmenu_driver\fP.
+.PP
+The function \fBset_item_init\fP sets a hook to be called at menu-post time and
+each time the selected item changes (after the change).
+\fBitem_init\fP
+returns the current item init hook, if any (\fBNULL\fP if there is no such
+hook).
+.PP
+The function \fBset_item_term\fP sets a hook to be called at menu-unpost time
+and each time the selected item changes (before the change).
+\fBitem_term\fP
+returns the current item term hook, if any (\fBNULL\fP if there is no such
+hook).
+.PP
+The function \fBset_menu_init\fP sets a hook to be called at menu-post time and
+just after the top row on the menu changes once it is posted.
+\fBmenu_init\fP
+returns the current menu init hook, if any (\fBNULL\fP if there is no such
+hook).
+.PP
+The function \fBset_menu_term\fP sets a hook to be called at menu-unpost time
+and just before the top row on the menu changes once it is posted.
+\fBmenu_term\fP returns the current menu term hook, if any (\fBNULL\fP if there
+is no such hook).
+.SH RETURN VALUE
+Routines that return pointers return \fBNULL\fP on error.
+Other routines
+return one of the following:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.SH SEE ALSO
+\fBcurses\fP(3X), \fBmenu\fP(3X).
+.SH NOTES
+The header file \fB<menu.h>\fP automatically includes the header file
+\fB<curses.h>\fP.
+.SH PORTABILITY
+These routines emulate the System V menu library.
+They were not supported on
+Version 7 or BSD versions.

+.SH DESCRIPTION
+In order to make menu selections visible on older terminals without

+in a menu with a prefix string.
+.PP
+The function \fBset_menu_mark\fP sets the mark string for the given menu.
+Calling \fBset_menu_mark\fP with a null menu item will abolish the mark string.
+Note that changing the length of the mark string for a menu while the
+menu is posted is likely to produce unhelpful behavior.
+.PP
+The default string is "\-" (a dash).
+Calling \fBset_menu_mark\fP with
+a non-\fBNULL\fP menu argument will change this default.
+.PP
+The function \fBmenu_mark\fP returns the menu's mark string (or \fBNULL\fP if

+The function \fBmenu_mark\fP returns a pointer (which may be \fBNULL\fP).

+O_IGNORECASE
+Ignore the case when pattern-matching.
+.TP 5
+O_SHOWMATCH
+Move the cursor to within the item name while pattern-matching.
+.TP 5
+O_NONCYCLIC
+Don't wrap around next-item and previous-item,
+requests to the other end of the menu.
+.TP 5
+O_MOUSE_MENU
+If user clicks with the mouse
+and it does not fall on the currently active menu,
+push \fBKEY_MOUSE\fP and the \fBMEVENT\fP data
+back on the queue to allow processing in another part of the calling program.
+.SH RETURN VALUE
+Except for \fBmenu_opts\fP, each routine returns one of the following:
+.TP 5
+.B E_OK
+The routine succeeded.

+.SH DESCRIPTION
+Every menu has an associated pattern match buffer.
+As input events that are
+printable characters come in, they are appended to this match buffer
+and tested for a match, as described in \fBmenu_driver\fP(3X).
+.PP
+The function \fBset_menu_pattern\fP sets the pattern buffer for the given menu

+The function \fBmenu_pattern\fP returns the pattern buffer of the given
+\fImenu\fP.
+.SH RETURN VALUE
+The function \fBmenu_pattern\fP returns a pointer,
+which is \fBNULL\fP if the \fImenu\fP parameter is \fBNULL\fP.
+Otherwise, it is a pointer to a string which is empty
+if no pattern has been set.

+.br
+.SH DESCRIPTION
+The function \fBset_menu_spacing\fP sets the spacing information for the menu.
+Its parameter \fBspc_description\fP controls the number of spaces
+between an item name and an item description.
+It must not be larger than \fBTABSIZE\fP.
+The menu system puts in the
+middle of this spacing area the pad character.
+The remaining parts are filled with
+spaces.
+The \fBspc_rows\fP parameter controls the number of rows
+that are used for an item.
+It must not be larger than 3.
+The menu system inserts the blank lines between item rows, these lines
+will contain the pad character in the appropriate positions.
+The \fBspc_columns\fP parameter controls
+the number of blanks between columns of items.
+It must not be larger than \fBTABSIZE\fP.
+A value of 0 for all the spacing values resets them to the default,
+which is 1 for all of them.
+.br
+The function \fBmenu_spacing\fP passes back the spacing info for the menu.
+If a
+pointer is NULL, this specific info is simply not returned.
+.SH RETURN VALUE
+Both routines return \fBE_OK\fP on success.
+\fBset_menu_spacing\fP may return
+\fBE_POSTED\fP if the menu is posted, or \fBE_BAD_ARGUMENT\fP if one of the
+spacing values is out of range.

+\fBWINDOW *menu_sub(const MENU *\fImenu\fB);\fR
+.sp
+\fBint scale_menu(const MENU *\fImenu, int *\fIrows\fB, int *\fIcolumns);\fR
+.br
+.SH DESCRIPTION
+Every menu has an associated pair of \fBcurses\fP windows.
+The menu window
+displays any title and border associated with the window; the menu subwindow
+displays the items of the menu that are currently available for selection.
+.PP
+The first four functions get and set those windows.
+It is not necessary to set
+either window; by default, the driver code uses \fBstdscr\fP for both.
+.PP
+In the \fBset_\fP functions, window argument of \fBNULL\fP is treated as though
+it were \fBstsdcr\fP.  A menu argument of \fBNULL\fP is treated as a request
+to change the system default menu window or subwindow.
+.PP
+The function \fBscale_menu\fP returns the minimum size required for the
+subwindow of \fImenu\fP.
+.SH RETURN VALUE
+Routines that return pointers return \fBNULL\fP on error.
+Routines that return
+an integer return one of the following error codes:
+.TP 5
+.B E_OK
+The routine succeeded.
+.TP 5
+.B E_SYSTEM_ERROR
+System error occurred (see \fBerrno\fP(3)).
+.TP 5
+.B E_BAD_ARGUMENT
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+.B E_POSTED
+The menu has already been posted.
+.TP 5
+.B E_NOT_CONNECTED
+No items are connected to the menu.

+.SH DESCRIPTION
+The function \fBset_current_item\fP sets the current item (the item on which
+the menu cursor is positioned).
+\fBcurrent_item\fP returns a pointer to the
+current item in the given menu.
+.PP
+The function \fBset_top_row\fP sets the top row of the menu to show the given
+row (the top row is initially 0, and is reset to this value whenever the
+\fBO_ROWMAJOR\fP option is toggled).
+The item leftmost on the given row
+becomes current.
+The function \fBtop_row\fP returns the number of the top menu
+row being displayed.
+.PP
+The function \fBitem_index\fP returns the (zero-origin) index of \fIitem\fP in
+the menu's item pointer list.
+.SH RETURN VALUE
+\fBcurrent_item\fP returns a pointer (which may be \fBNULL\fP).
+It does not set \fBerrno\fP.
+.PP
+\fBtop_row\fP and \fBitem_index\fP return \fBERR\fP (the general \fBcurses\fP
+error value) if their \fImenu\fP parameter is \fBNULL\fP.
+.PP
+\fBset_current_item\fP and \fBset_top_row\fP return one of the following:
+.TP 5
+.B E_OK
+The routine succeeded.

+.SH NAME
+\fBncurses\fP \- CRT screen handling and optimization package
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.br
+.SH DESCRIPTION
+The \fBncurses\fP library routines give the user a terminal-independent method
+of updating character screens with reasonable optimization.
+This implementation is \*(``new curses\*('' (ncurses) and
+is the approved replacement for
+4.4BSD classic curses, which has been discontinued.
+This describes \fBncurses\fP
+version @NCURSES_MAJOR@.@NCURSES_MINOR@ (patch @NCURSES_PATCH@).
+.PP
+The \fBncurses\fP library emulates the curses library of
+System V Release 4 UNIX,
+and XPG4 (X/Open Portability Guide) curses (also known as XSI curses).
+XSI stands for X/Open System Interfaces Extension.
+The \fBncurses\fP library is freely redistributable in source form.
+Differences from the SVr4
+curses are summarized under the
+\fIEXTENSIONS\fP and \fIPORTABILITY\fP sections below and
+described in detail in the respective
+\fIEXTENSIONS\fP, \fIPORTABILITY\fP and \fIBUGS\fP sections
+of individual man pages.
+.PP
+The \fBncurses\fP library also provides many useful extensions,
+i.e., features which cannot be implemented by a simple add-on library
+but which require access to the internals of the library.
+.PP
+A program using these routines must be linked with the \fB\-lncurses\fP option,
+or (if it has been generated) with the debugging library \fB\-lncurses_g\fP.
+(Your system integrator may also have installed these libraries under
+the names \fB\-lcurses\fP and \fB\-lcurses_g\fP.)
+The ncurses_g library generates trace logs (in a file called \*(``trace\*('' in the
+current directory) that describe curses actions.
+See also the section on \fBALTERNATE CONFIGURATIONS\fP.
+.PP
+The \fBncurses\fP package supports: overall screen, window and pad
+manipulation; output to windows and pads; reading terminal input; control over
+terminal and \fBcurses\fP input and output options; environment query
+routines; color manipulation; use of soft label keys; terminfo capabilities;
+and access to low-level terminal-manipulation routines.
+.SS Initialization
+.PP
+The library uses the locale which the calling program has initialized.
+That is normally done with \fBsetlocale\fP(3):
+.NS
+\fBsetlocale(LC_ALL, "");\fP
+.NE
+.PP
+If the locale is not initialized,
+the library assumes that characters are printable as in ISO\-8859\-1,
+to work with certain legacy programs.
+You should initialize the locale and not rely on specific details of
+the library when the locale has not been setup.
+.PP
+The function \fBinitscr\fP or \fBnewterm\fP
+must be called to initialize the library
+before any of the other routines that deal with windows
+and screens are used.
+The routine \fBendwin\fP(3X) must be called before exiting.
+.PP
+To get character-at-a-time input without echoing (most
+interactive, screen oriented programs want this), the following
+sequence should be used:
+.NS
+\fBinitscr(); cbreak(); noecho();\fP
+.NE
+.PP
+Most programs would additionally use the sequence:
+.NS
+\fBintrflush(stdscr, FALSE);\fP
+\fBkeypad(stdscr, TRUE);\fP
+.NE
+.PP
+Before a \fBcurses\fP program is run, the tab stops of the terminal
+should be set and its initialization strings, if defined, must be output.
+This can be done by executing the \fB@TPUT@ init\fP command
+after the shell environment variable \fBTERM\fP has been exported.
+\fB@TSET@(1)\fP is usually responsible for doing this.
+[See \fBterminfo\fP(\*n) for further details.]
+.SS Datatypes
+.PP
+The \fBncurses\fP library permits manipulation of data structures,
+called \fIwindows\fP, which can be thought of as two-dimensional
+arrays of characters representing all or part of a CRT screen.
+A default window called \fBstdscr\fP, which is the size of the terminal
+screen, is supplied.
+Others may be created with \fBnewwin\fP.
+.PP
+Note that \fBcurses\fP does not handle overlapping windows, that's done by
+the \fBpanel\fP(3X) library.
+This means that you can either use
+\fBstdscr\fP or divide the screen into tiled windows and not using
+\fBstdscr\fP at all.
+Mixing the two will result in unpredictable, and undesired, effects.
+.PP
+Windows are referred to by variables declared as \fBWINDOW *\fP.
+These data structures are manipulated with routines described here and
+elsewhere in the \fBncurses\fP manual pages.
+Among those, the most basic
+routines are \fBmove\fP and \fBaddch\fP.
+More general versions of
+these routines are included with names beginning with \fBw\fP,
+allowing the user to specify a window.
+The routines not beginning
+with \fBw\fP affect \fBstdscr\fP.
+.PP
+After using routines to manipulate a window, \fBrefresh\fP(3X) is called,
+telling \fBcurses\fP to make the user's CRT screen look like
+\fBstdscr\fP.
+The characters in a window are actually of type
+\fBchtype\fP, (character and attribute data) so that other information
+about the character may also be stored with each character.
+.PP
+Special windows called \fIpads\fP may also be manipulated.
+These are windows
+which are not constrained to the size of the screen and whose contents need not
+be completely displayed.
+See \fBcurs_pad\fP(3X) for more information.
+.PP
+In addition to drawing characters on the screen, video attributes and colors
+may be supported, causing the characters to show up in such modes as
+underlined, in reverse video, or in color on terminals that support such
+display enhancements.
+Line drawing characters may be specified to be output.
+On input, \fBcurses\fP is also able to translate arrow and function keys that
+transmit escape sequences into single values.
+The video attributes, line
+drawing characters, and input values use names, defined in \fB<curses.h>\fP,
+such as \fBA_REVERSE\fP, \fBACS_HLINE\fP, and \fBKEY_LEFT\fP.
+.SS Environment variables
+.PP
+If the environment variables \fBLINES\fP and \fBCOLUMNS\fP are set, or if the
+program is executing in a window environment, line and column information in
+the environment will override information read by \fIterminfo\fP.
+This would affect a program running in an AT&T 630 layer,
+for example, where the size of a
+screen is changeable (see \fBENVIRONMENT\fP).
+.PP
+If the environment variable \fBTERMINFO\fP is defined, any program using
+\fBcurses\fP checks for a local terminal definition before checking in the
+standard place.
+For example, if \fBTERM\fP is set to \fBatt4424\fP, then the
+compiled terminal definition is found in
+.NS
+\fB\*d/a/att4424\fP.
+.NE
+.PP
+(The \fBa\fP is copied from the first letter of \fBatt4424\fP to avoid
+creation of huge directories.)  However, if \fBTERMINFO\fP is set to
+\fB$HOME/myterms\fP, \fBcurses\fP first checks
+.NS
+\fB$HOME/myterms/a/att4424\fP,
+.NE
+.PP
+and if that fails, it then checks
+.NS
+\fB\*d/a/att4424\fP.
+.NE
+.PP
+This is useful for developing experimental definitions or when write
+permission in \fB\*d\fP is not available.
+.PP
+The integer variables \fBLINES\fP and \fBCOLS\fP are defined in
+\fB<curses.h>\fP and will be filled in by \fBinitscr\fP with the size of the
+screen.
+The constants \fBTRUE\fP and \fBFALSE\fP have the values \fB1\fP and
+\fB0\fP, respectively.
+.PP
+The \fBcurses\fP routines also define the \fBWINDOW *\fP variable \fBcurscr\fP
+which is used for certain low-level operations like clearing and redrawing a
+screen containing garbage.
+The \fBcurscr\fP can be used in only a few routines.
+.\"
+.SS Routine and Argument Names
+Many \fBcurses\fP routines have two or more versions.
+The routines prefixed with \fIw\fP require a window argument.
+The routines prefixed with \fIp\fP require a pad argument.
+Those without a prefix generally use \fBstdscr\fP.
+.PP
+The routines prefixed with \fBmv\fP require a \fIy\fP and \fIx\fP
+coordinate to move to before performing the appropriate action.
+The \fBmv\fP routines imply a call to \fBmove\fP before the call to the
+other routine.
+The coordinate \fIy\fP always refers to the row (of
+the window), and \fIx\fP always refers to the column.
+The upper left-hand corner is always (0,0), not (1,1).
+.PP
+The routines prefixed with \fBmvw\fP take both a window argument and
+\fIx\fP and \fIy\fP coordinates.
+The window argument is always specified before the coordinates.
+.PP
+In each case, \fIwin\fP is the window affected, and \fIpad\fP is the
+pad affected; \fIwin\fP and \fIpad\fP are always pointers to type
+\fBWINDOW\fP.
+.PP
+Option setting routines require a Boolean flag \fIbf\fP with the value
+\fBTRUE\fP or \fBFALSE\fP; \fIbf\fP is always of type \fBbool\fP.
+Most of the data types used in the library routines,
+such as \fBWINDOW\fP, \fBSCREEN\fP, \fBbool\fP, and \fBchtype\fP
+are defined in \fB<curses.h>\fP.
+Types used for the terminfo routines such as
+\fBTERMINAL\fP are defined in \fB<term.h>\fP.
+.PP
+This manual page describes functions which may appear in any configuration
+of the library.
+There are two common configurations of the library:
+.RS 3
+.TP 5
+.I ncurses
+the \*(``normal\*('' library, which handles 8-bit characters.
+The normal (8-bit) library stores characters combined with attributes
+in \fBchtype\fP data.
+.IP
+Attributes alone (no corresponding character) may be stored in \fBchtype\fP
+or the equivalent \fBattr_t\fP data.
+In either case, the data is stored in something like an integer.
+.IP
+Each cell (row and column) in a \fBWINDOW\fP is stored as a \fBchtype\fP.
+.TP 5
+.I ncursesw
+the so-called \*(``wide\*('' library, which handles multibyte characters
+(see the section on \fBALTERNATE CONFIGURATIONS\fP).
+The \*(``wide\*('' library includes all of the calls
+from the \*(``normal\*('' library.
+It adds about one third more calls using data types which store
+multibyte characters:
+.RS 5
+.TP 5
+.B cchar_t
+corresponds to \fBchtype\fP.
+However it is a structure, because more data is stored than can fit into
+an integer.
+The characters are large enough to require a full integer value \- and there
+may be more than one character per cell.
+The video attributes and color are stored in separate fields of the structure.
+.IP
+Each cell (row and column) in a \fBWINDOW\fP is stored as a \fBcchar_t\fP.
+.IP
+The \fBsetcchar\fP(3X) and \fBgetcchar\fP(3X)
+functions store and retrieve the data from
+a \fBcchar_t\fP structure.
+.TP 5
+.B wchar_t
+stores a \*(``wide\*('' character.
+Like \fBchtype\fP, this may be an integer.
+.TP 5
+.B wint_t
+stores a \fBwchar_t\fP or \fBWEOF\fP \- not the same, though both may have
+the same size.
+.RE
+.IP
+The \*(``wide\*('' library provides new functions which are analogous to
+functions in the \*(``normal\*('' library.
+There is a naming convention which relates many of the normal/wide variants:
+a \*(``_w\*('' is inserted into the name.
+For example, \fBwaddch\fP becomes \fBwadd_wch\fP.
+.RE

+the \*(``normal\*('' and \*(``wide\*('' libraries and the names of
+the manual pages on which they are described.

+.RE
+.SH RETURN VALUE
+Routines that return an integer return \fBERR\fP upon failure and an
+integer value other than \fBERR\fP upon successful completion, unless
+otherwise noted in the routine descriptions.
+.PP
+As a general rule, routines check for null pointers passed as parameters,
+and handle this as an error.
+.PP
+All macros return the value of the \fBw\fP version, except \fBsetscrreg\fP,
+\fBwsetscrreg\fP, \fBgetyx\fP, \fBgetbegyx\fP, and \fBgetmaxyx\fP.
+The return values of
+\fBsetscrreg\fP,
+\fBwsetscrreg\fP,
+\fBgetyx\fP,
+\fBgetbegyx\fP, and
+\fBgetmaxyx\fP are undefined (i.e., these should not be used as the
+right-hand side of assignment statements).
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
+Most \*(``mv\*(''-prefixed functions
+(except variadic functions such as \fBmvprintw\fP)
+are provided both as macros and functions.
+.PP
+Routines that return pointers return \fBNULL\fP on error.
+.SH ENVIRONMENT
+.PP
+The following environment symbols are useful for customizing the
+runtime behavior of the \fBncurses\fP library.
+The most important ones have been already discussed in detail.
+.SS CC command-character
+.PP
+When set, change occurrences of the command_character
+(i.e., the \fBcmdch\fP capability)
+of the loaded terminfo entries to the value of this variable.
+Very few terminfo entries provide this feature.
+.PP
+Because this name is also used in development environments to represent
+the C compiler's name, \fBncurses\fP ignores it if it does not happen to
+be a single character.
+.SS BAUDRATE
+.PP
+The debugging library checks this environment variable when the application
+has redirected output to a file.
+The variable's numeric value is used for the baudrate.
+If no value is found, \fBncurses\fP uses 9600.
+This allows testers to construct repeatable test-cases
+that take into account costs that depend on baudrate.
+.SS COLUMNS
+.PP
+Specify the width of the screen in characters.
+Applications running in a windowing environment usually are able to
+obtain the width of the window in which they are executing.
+If neither the \fBCOLUMNS\fP value nor the terminal's screen size is available,
+\fBncurses\fP uses the size which may be specified in the terminfo database
+(i.e., the \fBcols\fP capability).
+.PP
+It is important that your application use a correct size for the screen.
+This is not always possible because your application may be
+running on a host which does not honor NAWS (Negotiations About Window
+Size), or because you are temporarily running as another user.
+However, setting \fBCOLUMNS\fP and/or \fBLINES\fP overrides the library's
+use of the screen size obtained from the operating system.
+.PP
+Either \fBCOLUMNS\fP or \fBLINES\fP symbols may be specified independently.
+This is mainly useful to circumvent legacy misfeatures of terminal descriptions,
+e.g., xterm which commonly specifies a 65 line screen.
+For best results, \fBlines\fP and \fBcols\fP should not be specified in
+a terminal description for terminals which are run as emulations.
+.PP
+Use the \fBuse_env\fP function to disable all use of external environment
+(but not including system calls) to determine the screen size.
+Use the \fBuse_tioctl\fP function to update \fBCOLUMNS\fP or \fBLINES\fP
+to match the screen size obtained from system calls or the terminal database.
+.SS ESCDELAY
+.PP
+Specifies the total time, in milliseconds, for which ncurses will
+await a character sequence, e.g., a function key.
+The default value, 1000 milliseconds, is enough for most uses.
+However, it is made a variable to accommodate unusual applications.
+.PP
+The most common instance where you may wish to change this value
+is to work with slow hosts, e.g., running on a network.
+If the host cannot read characters rapidly enough, it will have the same
+effect as if the terminal did not send characters rapidly enough.
+The library will still see a timeout.
+.PP
+Note that xterm mouse events are built up from character sequences
+received from the xterm.
+If your application makes heavy use of multiple-clicking, you may
+wish to lengthen this default value because the timeout applies
+to the composed multi-click event as well as the individual clicks.
+.PP
+In addition to the environment variable,
+this implementation provides a global variable with the same name.
+Portable applications should not rely upon the presence of ESCDELAY
+in either form,
+but setting the environment variable rather than the global variable
+does not create problems when compiling an application.
+.SS HOME
+Tells \fBncurses\fP where your home directory is.
+That is where it may read and write auxiliary terminal descriptions:
+.NS
+$HOME/.termcap
+$HOME/.terminfo
+.NE
+.SS LINES
+.PP
+Like COLUMNS, specify the height of the screen in characters.
+See COLUMNS for a detailed description.
+.SS MOUSE_BUTTONS_123
+.PP
+This applies only to the OS/2 EMX port.
+It specifies the order of buttons on the mouse.
+OS/2 numbers a 3-button mouse inconsistently from other
+platforms:
+.NS
+1 = left
+.br
+2 = right
+.br
+3 = middle.
+.NE
+.PP
+This variable lets you customize the mouse.
+The variable must be three numeric digits 1\-3 in any order, e.g., 123 or 321.
+If it is not specified, \fBncurses\fP uses 132.
+.SS NCURSES_ASSUMED_COLORS
+.PP
+Override the compiled-in assumption that the
+terminal's default colors are white-on-black
+(see \fBdefault_colors\fP(3X)).
+You may set the foreground and background color values with this environment
+variable by proving a 2-element list: foreground,background.
+For example, to tell ncurses to not assume anything
+about the colors, set this to "\-1,\-1".
+To make it green-on-black, set it to "2,0".
+Any positive value from zero to the terminfo \fBmax_colors\fP value is allowed.
+.SS NCURSES_CONSOLE2
+This applies only to the MinGW port of ncurses.
+.PP
+The \fBConsole2\fP program's handling of the Microsoft Console API call
+\fBCreateConsoleScreenBuffer\fP is defective.
+Applications which use this will hang.
+However, it is possible to simulate the action of this call by
+mapping coordinates,
+explicitly saving and restoring the original screen contents.
+Setting the environment variable \fBNCGDB\fP has the same effect.
+.SS NCURSES_GPM_TERMS
+.PP
+This applies only to ncurses configured to use the GPM interface.
+.PP
+If present,
+the environment variable is a list of one or more terminal names
+against which the \fBTERM\fP environment variable is matched.
+Setting it to an empty value disables the GPM interface;
+using the built-in support for xterm, etc.
+.PP
+If the environment variable is absent,
+ncurses will attempt to open GPM if \fBTERM\fP contains \*(``linux\*(''.
+.SS NCURSES_NO_HARD_TABS
+.PP
+\fBNcurses\fP may use tabs as part of the cursor movement optimization.
+In some cases,
+your terminal driver may not handle these properly.
+Set this environment variable to disable the feature.
+You can also adjust your \fBstty\fP(1) settings to avoid the problem.
+.SS NCURSES_NO_MAGIC_COOKIE
+.PP
+Some terminals use a magic-cookie feature which requires special handling
+to make highlighting and other video attributes display properly.
+You can suppress the highlighting entirely for these terminals by
+setting this environment variable.
+.SS NCURSES_NO_PADDING
+.PP
+Most of the terminal descriptions in the terminfo database are written
+for real \*(``hardware\*('' terminals.
+Many people use terminal emulators
+which run in a windowing environment and use curses-based applications.
+Terminal emulators can duplicate
+all of the important aspects of a hardware terminal, but they do not
+have the same limitations.
+The chief limitation of a hardware terminal from the standpoint
+of your application is the management of dataflow, i.e., timing.
+Unless a hardware terminal is interfaced into a terminal concentrator
+(which does flow control),
+it (or your application) must manage dataflow, preventing overruns.
+The cheapest solution (no hardware cost)
+is for your program to do this by pausing after
+operations that the terminal does slowly, such as clearing the display.
+.PP
+As a result, many terminal descriptions (including the vt100)
+have delay times embedded.
+You may wish to use these descriptions,
+but not want to pay the performance penalty.
+.PP
+Set the NCURSES_NO_PADDING environment variable to disable all but mandatory
+padding.
+Mandatory padding is used as a part of special control
+sequences such as \fBflash\fP.
+.SS NCURSES_NO_SETBUF
+This setting is obsolete.
+Before changes
+.RS 3
+.bP
+started with 5.9 patch 20120825
+and
+.bP
+continued
+though 5.9 patch 20130126
+.RE
+.PP
+\fBncurses\fP enabled buffered output during terminal initialization.
+This was done (as in SVr4 curses) for performance reasons.
+For testing purposes, both of \fBncurses\fP and certain applications,
+this feature was made optional.
+Setting the NCURSES_NO_SETBUF variable
+disabled output buffering, leaving the output in the original (usually
+line buffered) mode.
+.PP
+In the current implementation,
+ncurses performs its own buffering and does not require this workaround.
+It does not modify the buffering of the standard output.
+.PP
+The reason for the change was to make the behavior for interrupts and
+other signals more robust.
+One drawback is that certain nonconventional programs would mix
+ordinary stdio calls with ncurses calls and (usually) work.
+This is no longer possible since ncurses is not using
+the buffered standard output but its own output (to the same file descriptor).
+As a special case, the low-level calls such as \fBputp\fP still use the
+standard output.
+But high-level curses calls do not.
+.SS NCURSES_NO_UTF8_ACS
+.PP
+During initialization, the \fBncurses\fP library
+checks for special cases where VT100 line-drawing (and the corresponding
+alternate character set capabilities) described in the terminfo are known
+to be missing.
+Specifically, when running in a UTF\-8 locale,
+the Linux console emulator and the GNU screen program ignore these.
+Ncurses checks the \fBTERM\fP environment variable for these.
+For other special cases, you should set this environment variable.
+Doing this tells ncurses to use Unicode values which correspond to
+the VT100 line-drawing glyphs.
+That works for the special cases cited,
+and is likely to work for terminal emulators.
+.PP
+When setting this variable, you should set it to a nonzero value.
+Setting it to zero (or to a nonnumber)
+disables the special check for \*(``linux\*('' and \*(``screen\*(''.
+.PP
+As an alternative to the environment variable,
+ncurses checks for an extended terminfo capability \fBU8\fP.
+This is a numeric capability which can be compiled using \fB@TIC@\ \-x\fP.
+For example
+.RS 3
+.ft CW
+.sp
+.nf
+# linux console, if patched to provide working
+# VT100 shift-in/shift-out, with corresponding font.
+linux-vt100|linux console with VT100 line-graphics,
+        U8#0, use=linux,
+.sp
+# uxterm with vt100Graphics resource set to false
+xterm-utf8|xterm relying on UTF-8 line-graphics,
+        U8#1, use=xterm,
+.fi
+.ft
+.RE
+.PP
+The name \*(``U8\*('' is chosen to be two characters,
+to permit it to be used by applications that use ncurses'
+termcap interface.
+.SS NCURSES_TRACE
+.PP
+During initialization, the \fBncurses\fP debugging library
+checks the NCURSES_TRACE environment variable.
+If it is defined, to a numeric value, \fBncurses\fP calls the \fBtrace\fP
+function, using that value as the argument.
+.PP
+The argument values, which are defined in \fBcurses.h\fP, provide several
+types of information.
+When running with traces enabled, your application will write the
+file \fBtrace\fP to the current directory.
+.PP
+See \fBcurs_trace\fP(3X) for more information.
+.SS TERM
+.PP
+Denotes your terminal type.
+Each terminal type is distinct, though many are similar.
+.PP
+\fBTERM\fP is commonly set by terminal emulators to help
+applications find a workable terminal description.
+Some of those choose a popular approximation, e.g.,
+\*(``ansi\*('', \*(``vt100\*('', \*(``xterm\*('' rather than an exact fit.
+Not infrequently, your application will have problems with that approach,
+e.g., incorrect function-key definitions.
+.PP
+If you set \fBTERM\fP in your environment,
+it has no effect on the operation of the terminal emulator.
+It only affects the way applications work within the terminal.
+Likewise, as a general rule (\fBxterm\fP(1) being a rare exception),
+terminal emulators which allow you to
+specify \fBTERM\fP as a parameter or configuration value do
+not change their behavior to match that setting.
+.SS TERMCAP
+If the \fBncurses\fP library has been configured with \fItermcap\fP
+support, \fBncurses\fP will check for a terminal's description in
+termcap form if it is not available in the terminfo database.
+.PP
+The \fBTERMCAP\fP environment variable contains
+either a terminal description (with newlines stripped out),
+or a file name telling where the information denoted by
+the \fBTERM\fP environment variable exists.
+In either case, setting it directs \fBncurses\fP to ignore
+the usual place for this information, e.g., /etc/termcap.
+.SS TERMINFO
+.PP
+\fBncurses\fP can be configured to read from multiple terminal databases.
+The \fBTERMINFO\fP variable overrides the location for
+the default terminal database.
+Terminal descriptions (in terminal format) are stored in terminal databases:
+.bP
+Normally these are stored in a directory tree,
+using subdirectories named by the first letter of the terminal names therein.
+.IP
+This is the scheme used in System V, which legacy Unix systems use,
+and the \fBTERMINFO\fP variable is used by \fIcurses\fP applications on those
+systems to override the default location of the terminal database.
+.bP
+If \fBncurses\fP is built to use hashed databases,
+then each entry in this list may be the path of a hashed database file, e.g.,
+.NS
+/usr/share/terminfo.db
+.NE
+.IP
+rather than
+.NS
+/usr/share/terminfo/
+.NE
+.IP
+The hashed database uses less disk-space and is a little faster than the
+directory tree.
+However,
+some applications assume the existence of the directory tree,
+reading it directly
+rather than using the terminfo library calls.
+.bP
+If \fBncurses\fP is built with a support for reading termcap files
+directly, then an entry in this list may be the path of a termcap file.
+.bP
+If the \fBTERMINFO\fP variable begins with
+\*(``hex:\*('' or \*(``b64:\*('',
+\fBncurses\fP uses the remainder of that variable as a compiled terminal
+description.
+You might produce the base64 format using \fBinfocmp\fP(1M):
+.NS
+TERMINFO="$(infocmp -0 -Q2 -q)"
+export TERMINFO
+.NE
+.IP
+The compiled description is used if it corresponds to the terminal identified
+by the \fBTERM\fP variable.
+.PP
+Setting \fBTERMINFO\fP is the simplest,
+but not the only way to set location of the default terminal database.
+The complete list of database locations in order follows:
+.RS 3
+.bP
+the last terminal database to which \fBncurses\fP wrote,
+if any, is searched first
+.bP
+the location specified by the TERMINFO environment variable
+.bP
+$HOME/.terminfo
+.bP
+locations listed in the TERMINFO_DIRS environment variable
+.bP
+one or more locations whose names are configured and compiled into the
+ncurses library, i.e.,
+.RS 3
+.bP
+@TERMINFO_DIRS@ (corresponding to the TERMINFO_DIRS variable)
+.bP
+@TERMINFO@ (corresponding to the TERMINFO variable)
+.RE
+.RE
+.PP
+.SS TERMINFO_DIRS
+.PP
+Specifies a list of locations to search for terminal descriptions.
+Each location in the list is a terminal database as described in
+the section on the \fBTERMINFO\fP variable.
+The list is separated by colons (i.e., ":") on Unix, semicolons on OS/2 EMX.
+.PP
+There is no corresponding feature in System V terminfo;
+it is an extension developed for \fBncurses\fP.
+.SS TERMPATH
+.PP
+If \fBTERMCAP\fP does not hold a file name then \fBncurses\fP checks
+the \fBTERMPATH\fP environment variable.
+This is a list of filenames separated by spaces or colons (i.e., ":") on Unix,
+semicolons on OS/2 EMX.
+.PP
+If the \fBTERMPATH\fP environment variable is not set,
+\fBncurses\fP looks in the files
+.NS
+/etc/termcap, /usr/share/misc/termcap and $HOME/.termcap,
+.NE
+.PP
+in that order.
+.PP
+The library may be configured to disregard the following variables when the
+current user is the superuser (root), or if the application uses setuid or
+setgid permissions:
+.NS
+$TERMINFO, $TERMINFO_DIRS, $TERMPATH, as well as $HOME.

+.PP
+Several different configurations are possible,
+depending on the configure script options used when building \fBncurses\fP.
+There are a few main options whose effects are visible to the applications
+developer using \fBncurses\fP:
+.TP 5
+\-\-disable\-overwrite
+The standard include for \fBncurses\fP is as noted in \fBSYNOPSIS\fP:
+.NS
+\fB#include <curses.h>\fP
+.NE
+.IP
+This option is used to avoid filename conflicts when \fBncurses\fP
+is not the main implementation of curses of the computer.
+If \fBncurses\fP is installed disabling overwrite, it puts its headers in
+a subdirectory, e.g.,
+.NS
+\fB#include <ncurses/curses.h>\fP
+.NE
+.IP
+It also omits a symbolic link which would allow you to use \fB\-lcurses\fP
+to build executables.
+.TP 5
+\-\-enable\-widec
+The configure script renames the library and
+(if the \fB\-\-disable\-overwrite\fP option is used)
+puts the header files in a different subdirectory.
+All of the library names have a \*(``w\*('' appended to them,
+i.e., instead of
+.NS
+\fB\-lncurses\fP
+.NE
+.IP
+you link with
+.NS
+\fB\-lncursesw\fP
+.NE
+.IP
+You must also enable the wide-character features in the header file
+when compiling for the wide-character library
+to use the extended (wide-character) functions.
+The symbol which enables these features has changed since XSI Curses, Issue 4:
+.RS
+.bP
+Originally, the wide-character feature required the symbol
+\fB_XOPEN_SOURCE_EXTENDED\fP
+but that was only valid for XPG4 (1996).
+.bP
+Later, that was deemed conflicting with \fB_XOPEN_SOURCE\fP defined to 500.
+.bP
+As of mid-2018,
+none of the features in this implementation require a \fB_XOPEN_SOURCE\fP
+feature greater than 600.
+However, X/Open Curses, Issue 7 (2009) recommends defining it to 700.
+.bP
+Alternatively, you can enable the feature by defining \fBNCURSES_WIDECHAR\fP
+with the caveat that some other header file than \fBcurses.h\fP
+may require a specific value for \fB_XOPEN_SOURCE\fP
+(or a system-specific symbol).
+.RE
+.IP
+The \fBcurses.h\fP file which is installed for the wide-character
+library is designed to be compatible with the normal library's header.
+Only the size of the \fBWINDOW\fP structure differs, and very few
+applications require more than a pointer to \fBWINDOW\fPs.
+.IP
+If the headers are installed allowing overwrite,
+the wide-character library's headers should be installed last,
+to allow applications to be built using either library
+from the same set of headers.
+.TP 5
+\-\-with\-pthread
+The configure script renames the library.
+All of the library names have a \*(``t\*('' appended to them
+(before any \*(``w\*('' added by \fB\-\-enable\-widec\fP).
+.IP
+The global variables such as \fBLINES\fP are replaced by macros to
+allow read-only access.
+At the same time, setter-functions are provided to set these values.
+Some applications (very few) may require changes to work with this convention.
+.TP 5
+\-\-with\-shared
+.TP
+\-\-with\-normal
+.TP
+\-\-with\-debug
+.TP
+\-\-with\-profile
+The shared and normal (static) library names differ by their suffixes,
+e.g., \fBlibncurses.so\fP and \fBlibncurses.a\fP.
+The debug and profiling libraries add a \*(``_g\*(''
+and a \*(``_p\*('' to the root names respectively,
+e.g., \fBlibncurses_g.a\fP and \fBlibncurses_p.a\fP.
+.TP 5
+\-\-with\-termlib
+Low-level functions which do not depend upon whether the library
+supports wide-characters, are provided in the tinfo library.
+.IP
+By doing this, it is possible to share the tinfo library between
+wide/normal configurations as well as reduce the size of the library
+when only low-level functions are needed.
+.IP
+Those functions are described in these pages:
+.RS
+.bP
+\fBcurs_extend\fP(3X) \- miscellaneous curses extensions
+.bP
+\fBcurs_inopts\fP(3X) \- \fBcurses\fP input options
+.bP
+\fBcurs_kernel\fP(3X) \- low-level \fBcurses\fP routines
+.bP
+\fBcurs_termattrs\fP(3X) \- \fBcurses\fP environment query routines
+.bP
+\fBcurs_termcap\fP(3X) \- \fBcurses\fP emulation of termcap
+.bP
+\fBcurs_terminfo\fP(3X) \- \fBcurses\fP interfaces to terminfo database
+.bP
+\fBcurs_util\fP(3X) \- miscellaneous \fBcurses\fP utility routines
+.RE
+.TP 5
+\-\-with\-trace
+The \fBtrace\fP function normally resides in the debug library,
+but it is sometimes useful to configure this in the shared library.
+Configure scripts should check for the function's existence rather
+than assuming it is always in the debug library.
+.SH FILES
+.TP 5
+@DATADIR@/tabset
+directory containing initialization files for the terminal capability database
+@TERMINFO@
+terminal capability database
+.SH SEE ALSO
+\fBterminfo\fP(\*n) and related pages whose names begin
+\*(``curs_\*('' for detailed routine descriptions.
+.br
+\fBcurs_variables\fP(3X)
+.br
+\fBuser_caps\fP(5) for user-defined capabilities
+.SH EXTENSIONS
+The \fBncurses\fP library can be compiled with an option (\fB\-DUSE_GETCAP\fP)
+that falls back to the old-style /etc/termcap file if the terminal setup code
+cannot find a terminfo entry corresponding to \fBTERM\fP.
+Use of this feature
+is not recommended, as it essentially includes an entire termcap compiler in
+the \fBncurses\fP startup code, at significant cost in core and startup cycles.
+.PP
+The \fBncurses\fP library includes facilities for capturing mouse events on
+certain terminals (including xterm).
+See the \fBcurs_mouse\fP(3X)
+manual page for details.
+.PP
+The \fBncurses\fP library includes facilities for responding to window
+resizing events, e.g., when running in an xterm.
+See the \fBresizeterm\fP(3X)
+and \fBwresize\fP(3X) manual pages for details.
+In addition, the library may be configured with a \fBSIGWINCH\fP handler.
+.PP
+The \fBncurses\fP library extends the fixed set of function key capabilities
+of terminals by allowing the application designer to define additional
+key sequences at runtime.
+See the \fBdefine_key\fP(3X)
+\fBkey_defined\fP(3X),
+and \fBkeyok\fP(3X) manual pages for details.
+.PP
+The \fBncurses\fP library can exploit the capabilities of terminals which
+implement the ISO\-6429 SGR 39 and SGR 49 controls, which allow an application
+to reset the terminal to its original foreground and background colors.
+From the users' perspective, the application is able to draw colored
+text on a background whose color is set independently, providing better
+control over color contrasts.
+See the \fBdefault_colors\fP(3X) manual page for details.
+.PP
+The \fBncurses\fP library includes a function for directing application output
+to a printer attached to the terminal device.
+See the \fBcurs_print\fP(3X) manual page for details.
+.SH PORTABILITY
+The \fBncurses\fP library is intended to be BASE-level conformant with XSI
+Curses.
+The EXTENDED XSI Curses functionality
+(including color support) is supported.
+.PP
+A small number of local differences (that is, individual differences between
+the XSI Curses and \fBncurses\fP calls) are described in \fBPORTABILITY\fP
+sections of the library man pages.
+.SS Error checking
+.PP
+In many cases, X/Open Curses is vague about error conditions,
+omitting some of the SVr4 documentation.
+.PP
+Unlike other implementations, this one checks parameters such as pointers
+to WINDOW structures to ensure they are not null.
+The main reason for providing this behavior is to guard against programmer
+error.
+The standard interface does not provide a way for the library
+to tell an application which of several possible errors were detected.
+Relying on this (or some other) extension will adversely affect the
+portability of curses applications.
+.SS Extensions versus portability
+.PP
+Most of the extensions provided by ncurses have not been standardized.
+Some have been incorporated into other implementations, such as
+PDCurses or NetBSD curses.
+Here are a few to consider:
+.bP
+The routine \fBhas_key\fP is not part of XPG4, nor is it present in SVr4.
+See the \fBcurs_getch\fP(3X) manual page for details.
+.bP
+The routine \fBslk_attr\fP is not part of XPG4, nor is it present in SVr4.
+See the \fBcurs_slk\fP(3X) manual page for details.
+.bP
+The routines \fBgetmouse\fP, \fBmousemask\fP, \fBungetmouse\fP,
+\fBmouseinterval\fP, and \fBwenclose\fP relating to mouse interfacing are not
+part of XPG4, nor are they present in SVr4.
+See the \fBcurs_mouse\fP(3X) manual page for details.
+.bP
+The routine \fBmcprint\fP was not present in any previous curses implementation.
+See the \fBcurs_print\fP(3X) manual page for details.
+.bP
+The routine \fBwresize\fP is not part of XPG4, nor is it present in SVr4.
+See the \fBwresize\fP(3X) manual page for details.
+.bP
+The WINDOW structure's internal details can be hidden from application
+programs.
+See \fBcurs_opaque\fP(3X) for the discussion of \fBis_scrollok\fP, etc.
+.bP
+This implementation can be configured to provide rudimentary support
+for multi-threaded applications.
+See \fBcurs_threads\fP(3X) for details.
+.bP
+This implementation can also be configured to provide a set of functions which
+improve the ability to manage multiple screens.
+See \fBcurs_sp_funcs\fP(3X) for details.
+.SS Padding differences
+.PP
+In historic curses versions, delays embedded in the capabilities \fBcr\fP,
+\fBind\fP, \fBcub1\fP, \fBff\fP and \fBtab\fP activated corresponding delay
+bits in the UNIX tty driver.
+In this implementation, all padding is done by sending NUL bytes.
+This method is slightly more expensive, but narrows the interface
+to the UNIX kernel significantly and increases the package's portability
+correspondingly.
+.SS Header files
+The header file \fB<curses.h>\fP automatically includes the header files
+\fB<stdio.h>\fP and \fB<unctrl.h>\fP.
+.PP
+X/Open Curses has more to say,
+but does not finish the story:
+.RS 4
+.PP
+The inclusion of <curses.h> may make visible all symbols
+from the headers <stdio.h>, <term.h>, <termios.h>, and <wchar.h>.
+.RE
+.PP
+Here is a more complete story:
+.bP
+Starting with BSD curses, all implementations have included <stdio.h>.
+.IP
+BSD curses included <curses.h> and <unctrl.h> from an internal header
+"curses.ext" ("ext" was a short name for \fIexterns\fP).
+.IP
+BSD curses used <stdio.h> internally (for \fBprintw\fP and \fBscanw\fP),
+but nothing in <curses.h> itself relied upon <stdio.h>.
+.bP
+SVr2 curses added \fBnewterm\fP(3X), which relies upon <stdio.h>.
+That is, the function prototype uses \fBFILE\fP.
+.IP
+SVr4 curses added \fBputwin\fP and \fBgetwin\fP, which also use <stdio.h>.
+.IP
+X/Open Curses documents all three of these functions.
+.IP
+SVr4 curses and X/Open Curses do not require the developer to
+include <stdio.h> before including <curses.h>.
+Both document curses showing <curses.h> as the only required header.
+.IP
+As a result, standard <curses.h> will always include <stdio.h>.
+.bP
+X/Open Curses is inconsistent with respect to SVr4 regarding <unctrl.h>.
+.IP
+As noted in \fBcurs_util\fP(3X), ncurses includes <unctrl.h> from
+<curses.h> (like SVr4).
+.bP
+X/Open's comments about <term.h> and <termios.h> may refer to HP-UX and AIX:
+.IP
+HP-UX curses includes <term.h> from <curses.h>
+to declare \fBsetupterm\fP in curses.h,
+but ncurses (and Solaris curses) do not.
+.IP
+AIX curses includes <term.h> and <termios.h>.
+Again, ncurses (and Solaris curses) do not.
+.bP
+X/Open says that <curses.h> \fImay\fP include <term.h>,
+but there is no requirement that it do that.
+.IP
+Some programs use functions declared in both <curses.h> and <term.h>,
+and must include both headers in the same module.
+Very old versions of AIX curses required including <curses.h>
+before including <term.h>.
+.IP
+Because ncurses header files include the headers needed to
+define datatypes used in the headers,
+ncurses header files can be included in any order.
+But for portability, you should include <curses.h> before <term.h>.
+.bP
+X/Open Curses says \fI"may make visible"\fP
+because including a header file does not necessarily make all symbols
+in it visible (there are ifdef's to consider).
+.IP
+For instance, in ncurses <wchar.h> \fImay\fP be included if
+the proper symbol is defined, and if ncurses is configured for
+wide-character support.
+If the header is included, its symbols may be made visible.
+That depends on the value used for \fB_XOPEN_SOURCE\fP
+feature test macro.
+.bP
+X/Open Curses documents one required header,
+in a special case: <stdarg.h> before <curses.h> to prototype
+the \fBvw_printw\fP and \fBvw_scanw\fP functions
+(as well as the obsolete
+the \fBvwprintw\fP and \fBvwscanw\fP functions).
+Each of those uses a \fBva_list\fP parameter.
+.IP
+The two obsolete functions were introduced in SVr3.
+The other functions were introduced in X/Open Curses.
+In between, SVr4 curses provided for the possibility that
+an application might include either <varargs.h> or <stdarg.h>.
+Initially, that was done by using \fBvoid*\fP for the \fBva_list\fP
+parameter.
+Later, a special type (defined in <stdio.h>) was introduced,
+to allow for compiler type-checking.
+That special type is always available,
+because <stdio.h> is always included by <curses.h>.
+.IP
+None of the X/Open Curses implementations require an application
+to include <stdarg.h> before <curses.h> because they either
+have allowed for a special type, or (like ncurses) include <stdarg.h>
+directly to provide a portable interface.
+.SH NOTES
+.PP
+If standard output from a \fBncurses\fP program is re-directed to something
+which is not a tty, screen updates will be directed to standard error.
+This was an undocumented feature of AT&T System V Release 3 curses.

+.SH NAME
+\fBalloc_pair\fP,
+\fBfind_pair\fP,
+\fBfree_pair\fP \- new curses color-pair functions
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint alloc_pair(int \fIfg\fB, int \fIbg\fB);\fR
+.br
+\fBint find_pair(int \fIfg\fB, int \fIbg\fB);\fR
+.br
+\fBint free_pair(int \fIpair\fB);\fR
+.SH DESCRIPTION
+These functions are an extension to the curses library.
+They permit an application to dynamically allocate a color pair using
+the foreground/background colors rather than assign a fixed color pair number,
+and return an unused pair to the pool.
+.PP
+The number of colors may be related to the number of possible color
+pairs for a given terminal, or it may not:
+.bP
+While almost all terminals allow setting the color \fIattributes\fP
+independently,
+it is unlikely that your terminal allows you to modify the attributes
+of a given character cell without rewriting it.
+That is, the foreground and background colors are applied as a pair.
+.bP
+Color pairs are the curses library's way of managing a color palette
+on a terminal.
+If the library does not keep track of the \fIcombinations\fP of
+colors which are displayed, it will be inefficient.
+.bP
+For simple terminal emulators
+with only a few dozen color combinations,
+it is convenient to use the maximum number of combinations
+as the limit on color pairs:
+.NS
+\fBCOLORS\fI * \fBCOLORS\fR
+.NE
+.bP
+Terminals which support \fIdefault colors\fP distinct
+from \*(``ANSI colors\*(''
+add to the possible combinations, producing this total:
+.NS
+\fI( \fBCOLORS\fI + 1 ) * ( \fBCOLORS\fI + 1 )\fR
+.NE
+.bP
+An application might use up to a few dozen color pairs to
+implement a predefined color scheme.
+.IP
+Beyond that lies in the realm of programs using the foreground
+and background colors for \*(``ASCII art\*(''
+(or some other non-textual application).
+.IP
+Also beyond those few dozen pairs, the required size for a table
+to represent the combinations grows rapidly with an increasing number of colors.
+.IP
+These functions allow a developer to let the screen library
+manage color pairs.
+.SS alloc_pair
+The \fBalloc_pair\fP function accepts parameters for
+foreground and background color, and
+checks if that color combination is already associated with a color pair.
+.bP
+If the combination already exists,
+\fBalloc_pair\fP returns the existing pair.
+.bP
+If the combination does not exist,
+\fBalloc_pair\fP allocates a new color pair and returns that.
+.bP
+If the table fills up, \fBalloc_pair\fP discards the least-recently
+allocated entry using \fBfree_pair\fP and allocates a new color pair.
+.PP
+All of the color pairs are allocated from a table of possible color pairs.
+The size of the table is determined by the terminfo \fBpairs\fP capability.
+The table is shared with \fBinit_pair\fP;
+in fact \fBalloc_pair\fP calls \fBinit_pair\fP after
+updating the ncurses library's fast index to the colors versus color pairs.
+.SS find_pair
+The \fBfind_pair\fP function accepts parameters for
+foreground and background color, and
+checks if that color combination is already associated with a color pair,
+returning the pair number if it has been allocated.
+Otherwise it returns \-1.
+.SS free_pair
+Marks the given color pair as unused,
+i.e., like color pair 0.
+.SH RETURN VALUE
+.PP
+The \fBalloc_pair\fP function returns a color pair number in the range
+1 through \fBCOLOR_PAIRS\fP\-1, unless it encounters an error updating
+its fast index to the color pair values, preventing it from allocating
+a color pair.
+In that case, it returns \-1.
+.PP
+The \fBfind_pair\fP function returns a color pair number if the
+given color combination has been associated with a color pair,
+or \-1 if not.
+.PP
+Likewise, \fBfree_pair\fP returns \fBOK\fP unless it encounters an
+error updating the fast index or if no such color pair is in use.
+.SH PORTABILITY
+These routines are specific to ncurses.
+They were not supported on
+Version 7, BSD or System V implementations.
+It is recommended that
+any code depending on them be conditioned using NCURSES_VERSION.

+.SH DESCRIPTION
+Panels are \fBcurses\fP(3X) windows with the added feature of
+depth.
+Panel functions allow the use of stacked windows and ensure
+the proper portions of each window and the curses \fBstdscr\fP window are
+hidden or displayed when panels are added, moved, modified or removed.
+The set of currently visible panels is the stack of panels.
+The
+\fBstdscr\fP window is beneath all panels, and is not considered part
+of the stack.
+.P
+A window is associated with every panel.
+The panel routines enable
+you to create, move, hide, and show panels, as well as position a
+panel at any desired location in the stack.
+.P
+Panel routines are a functional layer added to \fBcurses\fP(3X), make only
+high-level curses calls, and work anywhere terminfo curses does.
+.SH FUNCTIONS
+.\" ---------
+.SS bottom_panel
+\fBbottom_panel(\fIpan\fB)\fR
+puts panel \fIpan\fP at the bottom of all panels.
+.\" ---------
+.SS ceiling_panel
+\fBceiling_panel(\fIsp\fB)\fR
+acts like \fBpanel_below(NULL)\fP, for the given \fBSCREEN\fP \fIsp\fP.
+.\" ---------
+.SS del_panel
+\fBdel_panel(\fIpan\fB)\fR
+removes the given panel \fIpan\fP from the  stack and deallocates the
+\fBPANEL\fP structure (but not its associated window).
+.\" ---------
+.SS ground_panel
+\fBground_panel(\fIsp\fB)\fR
+acts like \fBpanel_above(NULL)\fP, for the given \fBSCREEN\fP \fIsp\fP.
+.\" ---------
+.SS hide_panel
+\fBhide_panel(\fIpan\fB)\fR
+removes the given panel \fIpan\fP from the panel stack
+and thus hides it from view.
+The \fBPANEL\fP structure is not lost, merely removed from the stack.
+.\" ---------
+.SS move_panel
+\fBmove_panel(\fIpan\fB,\fIstarty\fB,\fIstartx\fB)\fR
+moves the given panel \fIpan\fP's window so that its upper-left corner is at
+\fIstarty\fP, \fIstartx\fP.
+It does not change the position of the panel in the stack.
+Be sure to use this function, not \fBmvwin\fP(3X), to move a panel window.
+.\" ---------
+.SS new_panel
+\fBnew_panel(\fIwin\fB)\fR allocates a \fBPANEL\fR structure,
+associates it with \fIwin\fP, places the panel on the top of the stack
+(causes  it to  be  displayed above any other panel) and returns a
+pointer to the new panel.
+.\" ---------
+.SS panel_above
+\fBpanel_above(\fIpan\fB)\fR
+returns a pointer to the panel above \fIpan\fP.
+If the panel argument is
+\fB(PANEL *)0\fP, it returns a pointer to the bottom panel in the stack.
+.\" ---------
+.SS panel_below
+\fBpanel_below(\fIpan\fB)\fR
+returns a pointer to the panel just below \fIpan\fP.
+If the panel argument
+is \fB(PANEL *)0\fP, it returns a pointer to the top panel in the stack.
+.\" ---------
+.SS panel_hidden
+\fBpanel_hidden(\fIpan\fB)\fR
+returns \fBTRUE\fP if the panel \fIpan\fP is in the panel stack,
+\fBFALSE\fP if it is not.
+If the panel is a null pointer, return \fBERR\fP.
+.\" ---------
+.SS panel_userptr
+\fBpanel_userptr(\fIpan\fB)\fR
+returns the user pointer for a given panel \fIpan\fP.
+.\" ---------
+.SS panel_window
+\fBpanel_window(\fIpan\fB)\fR
+returns a pointer to the window of the given panel \fIpan\fP.
+.\" ---------
+.SS replace_panel
+\fBreplace_panel(\fIpan\fB,\fIwindow\fB)\fR
+replaces the current window of panel \fIpan\fP with \fIwindow\fP
+This is useful, for example if you want to resize a panel.
+In \fBncurses\fP, you can call \fBreplace_panel\fP
+to resize a panel using a window resized with \fBwresize\fP(3X).
+It does not change the position of the panel in the stack.
+.\" ---------
+.SS set_panel_userptr
+\fBset_panel_userptr(\fIpan\fB,\fIptr\fB)\fR
+sets the panel's user pointer.
+.\" ---------
+.SS show_panel
+\fBshow_panel(\fIpan\fB)\fR
+makes a hidden panel visible by placing it on top of the panels in the
+panel stack.
+See \fBCOMPATIBILITY\fP below.
+.\" ---------
+.SS top_panel
+\fBtop_panel(\fIpan\fB)\fR
+puts the given visible panel \fIpan\fP on top of all panels in the stack.
+See \fBCOMPATIBILITY\fP below.
+.\" ---------
+.SS update_panels
+\fBupdate_panels()\fR
+refreshes the \fIvirtual screen\fP to reflect the relations between the
+panels in the stack, but does not call \fBdoupdate\fP(3X) to refresh the
+\fIphysical screen\fP.
+Use this function and not \fBwrefresh\fP(3X) or \fBwnoutrefresh\fP(3X).
+.PP
+\fBupdate_panels\fP may be called more than once before a call to
+\fBdoupdate\fP, but \fBdoupdate\fP is the function responsible for updating
+the \fIphysical screen\fP.
+.SH DIAGNOSTICS
+Each routine that returns a pointer returns \fBNULL\fP if an error
+occurs.
+Each routine that returns an int value returns \fBOK\fP if it
+executes successfully and \fBERR\fP if not.
+.PP
+Except as noted, the \fIpan\fP and \fIwindow\fP parameters must be non-null.
+If those are null, an error is returned.
+.PP
+The \fBmove_panel\fP function uses \fBmvwin\fP(3X),
+and will return an error if \fBmvwin\fP returns an error.
+.SH COMPATIBILITY
+Reasonable care has been taken to  ensure  compatibility
+with  the  native  panel facility introduced in System V (inspection of
+the SVr4 manual pages suggests the programming interface is unchanged).
+The \fBPANEL\fP data structures are merely  similar.
+The  programmer
+is cautioned not to directly use \fBPANEL\fP fields.
+.P
+The functions \fBshow_panel\fP and \fBtop_panel\fP are identical
+in this implementation, and work equally well with displayed or hidden
+panels.
+In the native System V implementation, \fBshow_panel\fP is
+intended for making a hidden panel visible (at the top of the stack)
+and \fBtop_panel\fP is intended for making an already-visible panel
+move to the top of the stack.
+You are cautioned to use the correct
+function to ensure compatibility with native panel libraries.
+.SH NOTE
+In your library list, libpanel.a should be before libncurses.a; that is,
+you should say \*(``\-lpanel \-lncurses\*('', not the other way around
+(which would give a link-error with static libraries).
+.SH PORTABILITY
+.PP
+The panel facility was documented in SVr4.2 in
+\fICharacter User Interface Programming (UNIX SVR4.2)\fP.
+.PP
+It is not part of X/Open Curses.
+.PP
+A few implementations exist:
+.bP
+Systems based on SVr4 source code,
+e.g., Solaris, provide this library.
+.bP
+\fBncurses\fP (since version 0.6 in 1993)
+and \fBPDCurses\fP (since version 2.2 in 1995)
+provide a panel library whose common ancestor
+was a public domain implementation by Warren Tucker
+published in \fIu386mon\fP 2.20 (1990).
+.IP
+According to Tucker, the SystemV panel library
+was first released in SVr3.2 (1988),
+and his implementation helped with a port to SVr3.1 (1987).
+.IP
+Several developers have improved each of these;
+they are no longer the same as Tucker's implementation.
+.bP
+NetBSD 8 (2018)
+has a panel library begun by Valery Ushakov in 2015.
+This is based on the AT&T documentation.

+.SH DESCRIPTION
+.PP
+This is an extension to the curses library.
+It provides callers with a hook into the \fBncurses\fP data to resize windows,
+primarily for use by programs running in an X Window terminal (e.g., xterm)
+when the terminal's screen size is changed by the user:
+.bP
+Curses windows cannot extend outside the screen.
+If the terminal is shrunk, curses windows must be shrunk to fit.
+.bP
+If the terminal is stretched,
+rows and/or columns can be added to existing windows.
+The added cells should match the current attributes of the windows.
+.PP
+If the calling program has not set up a handler for \fBSIGWINCH\fP
+when it initializes \fBncurses\fP
+(e.g., using \fBinitscr\fP(3X) or \fBnewterm\fP(3X)),
+then \fBncurses\fP sets a handler for \fBSIGWINCH\fP which notifies
+the library when a window-size event has occurred.
+The library checks for this notification
+.bP
+when reading input data,
+.bP
+when implicitly resuming program mode
+(e.g., between \fBendwin\fP(3X) and \fBwrefresh\fP(3X)),
+and
+.bP
+when explicitly resuming program mode in \fBrestartterm\fP(3X).
+.PP
+When the library has found that the terminal's window-size has
+changed, it calls \fBresizeterm\fP to update its data structures.
+.PP
+An application which establishes its own \fBSIGWINCH\fP handler
+can call \fBresizeterm\fP, but in that case, the library will not
+see \fBSIGWINCH\fP, and proper layout will rely upon the application.
+.SH FUNCTIONS
+.SS resizeterm
+.PP
+The function \fBresizeterm\fP resizes the standard and current windows
+(i.e., \fBstdscr\fP and \fBcurscr\fP)
+to the specified dimensions, and adjusts other bookkeeping data used by
+the \fBncurses\fP library that record the window dimensions
+such as the \fBLINES\fP and \fBCOLS\fP variables.
+.SS resize_term
+.PP
+Most of the work for \fBresizeterm\fP is
+done by the inner function \fBresize_term\fP.
+The outer function \fBresizeterm\fP adds bookkeeping
+for the \fBSIGWINCH\fP handler,
+as well as repainting the soft-key area (see \fBslk_touch\fP(3X)).
+.PP
+The \fBresize_term\fP function attempts to resize all windows.
+This helps with simple applications.
+However:
+.bP
+It is not possible to automatically resize pads.
+.bP
+Applications which have complicated layouts should check for
+\fBKEY_RESIZE\fP returned from \fBwgetch\fP,
+and adjust their layout, e.g., using \fBwresize\fP and \fBmvwin\fP,
+or by recreating the windows.
+.PP
+When resizing windows, \fBresize_term\fP recursively adjusts subwindows,
+keeping them within the updated parent window's limits.
+If a top-level window happens to extend to the screen's limits,
+then on resizing the window, \fBresize_term\fP will keep the window
+extending to the corresponding limit, regardless of whether the
+screen has shrunk or grown.
+.SS is_term_resized
+.PP
+A support function \fBis_term_resized\fP is provided so that applications
+can check if the \fBresize_term\fP function would modify the window structures.
+It returns \fBTRUE\fP if the windows would be modified,
+and \fBFALSE\fP otherwise.
+.SH RETURN VALUE
+Except as noted, these functions return
+the integer \fBERR\fP upon failure and \fBOK\fP on success.
+They will fail if either of the dimensions are less than or equal to zero,
+or if an error occurs while (re)allocating memory for the windows.
+.SH NOTES
+While these functions are intended to be used to support a signal handler
+(i.e., for \fBSIGWINCH\fP), care should be taken to avoid invoking them in a
+context where \fBmalloc\fP or \fBrealloc\fP may have been interrupted,
+since it uses those functions.
+.PP
+If ncurses is configured to supply its own \fBSIGWINCH\fP handler,
+.bP
+on receipt of a \fBSIGWINCH\fP, the handler sets a flag
+.bP
+which is tested in
+\fBwgetch\fP(3X),
+\fBdoupdate\fP(3X) and
+\fBrestartterm\fP(3X),
+.bP
+in turn, calling the \fBresizeterm\fP function,
+.bP
+which \fBungetch\fP's a \fBKEY_RESIZE\fP which
+will be read on the next call to \fBwgetch\fP.
+.IP
+The \fBKEY_RESIZE\fP alerts an application that the screen size has changed,
+and that it should repaint special features such as pads that cannot
+be done automatically.
+.IP
+Calling \fBresizeterm\fP or \fBresize_term\fP
+directly from a signal handler is unsafe.
+This indirect method is used to provide a safe way to resize the ncurses
+data structures.
+.PP
+If the environment variables \fBLINES\fP or \fBCOLUMNS\fP are set,
+this overrides the library's use of the window size obtained from
+the operating system.
+Thus, even if a \fBSIGWINCH\fP is received,
+no screen size change may be recorded.
+.SH PORTABILITY
+.PP
+It is possible to resize the screen with SVr4 curses,
+by
+.bP
+exiting curses with \fBendwin\fP(3X) and
+.bP
+resuming using \fBrefresh\fP(3X).
+.PP
+Doing that clears the screen and is visually distracting.
+.PP
+This extension of ncurses was introduced in mid-1995.
+It was adopted in NetBSD curses (2001) and PDCurses (2003).

+.SH NAME
+scr_dump \- format of curses screen-dumps.
+.SH SYNOPSIS
+.B scr_dump
+.SH DESCRIPTION
+.PP
+The curses library provides applications with the ability to write the
+contents of a window to an external file using \fBscr_dump\fP or \fBputwin\fP,
+and read it back using \fBscr_restore\fP or \fBgetwin\fP.
+.PP
+The \fBputwin\fP and \fBgetwin\fP functions do the work;
+while \fBscr_dump\fP and \fBscr_restore\fP conveniently save and restore
+the whole screen, i.e., \fBstdscr\fP.
+.SS ncurses6
+.PP
+A longstanding implementation of screen-dump was
+revised with ncurses6 to remedy problems with the earlier approach:
+.bP
+A \*(``magic number\*('' is written to the beginning of the dump file,
+allowing applications (such as \fBfile\fP(1)) to recognize curses dump files.
+.IP
+Because ncurses6 uses a new format,
+that requires a new magic number
+was unused by other applications.
+This 16-bit number was unused:
+.NS
+0x8888 (octal \*(``\\210\\210\*('')
+.NE
+.IP
+but to be more certain, this 32-bit number was chosen:
+.NS
+0x88888888 (octal \*(``\\210\\210\\210\\210\*('')
+.NE
+.IP
+This is the pattern submitted to the maintainers of the \fBfile\fP program:
+.NS
+#
+# ncurses5 (and before) did not use a magic number,
+# making screen dumps "data".
+#
+# ncurses6 (2015) uses this format, ignoring byte-order
+0    string    \\210\\210\\210\\210ncurses    ncurses6 screen image
+#

+The screen dumps are written in textual form,
+so that internal data sizes are not directly related to the dump-format, and
+enabling the library to read dumps from either narrow- or wide-character-
+configurations.
+.IP
+The \fInarrow\fP library configuration holds characters and video attributes
+in a 32-bit \fBchtype\fP, while the \fIwide-character\fP library stores
+this information in the \fBcchar_t\fP structure, which is much larger than
+32-bits.
+.bP
+It is possible to read a screen dump into a terminal with a different
+screen-size,
+because the library truncates or fills the screen as necessary.
+.bP
+The ncurses6 \fBgetwin\fP reads the legacy screen dumps from ncurses5.
+.SS ncurses5 (legacy)
+.PP
+The screen-dump feature was added to ncurses in June 1995.
+While there were fixes and improvements in succeeding years,
+the basic scheme was unchanged:
+.bP
+The \fBWINDOW\fP structure was written in binary form.
+.bP
+The \fBWINDOW\fP structure refers to lines of data,
+which were written as an array of binary data following the \fBWINDOW\fP.
+.bP
+When \fBgetwin\fP restored the window,
+it would keep track of offsets into the array of line-data
+and adjust the \fBWINDOW\fP structure which was read back into memory.
+.PP
+This is similar to Unix SystemV,
+but does not write a \*(``magic number\*('' to identify the file format.
+.SH PORTABILITY
+.PP
+There is no standard format for \fBputwin\fP.
+This section gives a brief description of the existing formats.
+.SS X/Open Curses
+.PP
+Refer to \fIX/Open Curses, Issue 7\fP (2009).
+.PP
+X/Open's documentation for \fIenhanced curses\fP says only:
+.RS 3
+.PP
+The \fBgetwin(\ ) \fPfunction reads window-related data
+stored in the file by \fIputwin(\ )\fP.
+The function
+then creates and initializes a new window using that data.
+.PP
+The \fBputwin(\ )\fP function writes all data associated
+with \fIwin\fP into the \fBstdio\fP(3) stream to which \fIfilep\fP
+points, using an \fBunspecified format\fP.
+This information can be retrieved later using \fBgetwin(\ )\fP.
+.RE
+.PP
+In the mid-1990s when the X/Open Curses document was written,
+there were still systems using older, less capable curses libraries
+(aside from the BSD curses library which was not relevant to X/Open
+because it did not meet the criteria for \fIbase curses\fP).
+The document explained the term \*(``enhanced\*('' as follows:
+.RS 3
+.bP
+Shading is used to identify \fIX/Open Enhanced Curses\fP material,
+relating to interfaces included to provide enhanced capabilities
+for applications originally written to be compiled on systems
+based on the UNIX operating system.
+Therefore, the features described may not be present on systems
+that conform to \fBXPG4 or to earlier XPG releases\fP.
+The relevant reference pages may provide additional
+or more specific portability warnings about use of the material.
+.RE
+.PP
+In the foregoing, emphasis was added to \fBunspecified format\fP
+and to \fBXPG4 or to earlier XPG releases\fP,
+for clarity.
+.SS Unix SystemV
+.PP
+Unix SystemV curses identified the file format by writing a
+\*(``magic number\*('' at the beginning of the dump.
+The \fBWINDOW\fP data and the lines of text follow, all in binary form.
+.PP
+The Solaris curses source has these definitions:
+.NS
+/* terminfo magic number */
+#define MAGNUM  0432
+
+/* curses screen dump magic number */
+#define SVR2_DUMP_MAGIC_NUMBER  0433
+#define SVR3_DUMP_MAGIC_NUMBER  0434
+.NE
+.PP
+That is, the feature was likely introduced in SVr2 (1984),
+and improved in SVr3 (1987).
+The Solaris curses source has no magic number for SVr4 (1989).
+Other operating systems (AIX and HPUX) use a magic number which would
+correspond to this definition:
+.NS
+/* curses screen dump magic number */
+#define SVR4_DUMP_MAGIC_NUMBER  0435
+.NE
+.PP
+That octal number in bytes is 001, 035.
+Because most Unix vendors use big-endian hardware,
+the magic number is written with the high-order byte first, e.g.,
+.NS
+\001\035
+.NE
+.PP
+After the magic number, the \fBWINDOW\fP structure and line-data are
+written in binary format.
+While the magic number used by the Unix systems can be seen using \fBod\fP(1),
+none of the Unix systems documents the format used for screen-dumps.
+.PP
+The Unix systems do not use identical formats.
+While collecting information for for this manual page,
+the \fIsavescreen\fP test-program
+produced dumps of different size
+(all on 64-bit hardware, on 40x80 screens):
+.bP
+AIX (51817 bytes)
+.bP
+HPUX (90093 bytes)
+.bP
+Solaris 10 (13273 bytes)
+.bP
+ncurses5 (12888 bytes)
+.SS Solaris
+.PP
+As noted above, Solaris curses has no magic number corresponding
+to SVr4 curses.
+This is odd since Solaris was the first operating system
+to pass the SVr4 guidelines.
+Solaris has two versions of curses:
+.bP
+The default curses library uses the SVr3 magic number.
+.bP
+There is an alternate curses library in \fB/usr/xpg4\fP.
+This uses a textual format with no magic number.
+.IP
+According to the copyright notice, the \fIxpg4\fP Solaris curses library was
+developed by MKS (Mortice Kern Systems) from 1990 to 1995.
+.IP
+Like ncurses6, there is a file-header with parameters.
+Unlike ncurses6, the contents of the window are written piecemeal,
+with coordinates and attributes for each chunk of text rather
+than writing the whole window from top to bottom.
+.SS PDCurses
+.PP
+PDCurses added support for screen dumps in version 2.7 (2005).
+Like Unix SystemV and ncurses5,
+it writes the \fBWINDOW\fP structure in binary,
+but begins the file with its three-byte identifier \*(``PDC\*('',
+followed by a one-byte version,
+e.g.,
+.NS
+	\*(``PDC\\001\*(''
+.NE
+.SS NetBSD
+.PP
+As of April 2017, NetBSD curses does
+not support \fBscr_dump\fP and \fBscr_restore\fP
+(or \fBscr_init\fP, \fBscr_set\fP),
+although it has \fBputwin\fP and \fBgetwin\fP.
+.PP
+Like ncurses5, NetBSD \fBputwin\fP does not identify its dumps with a
+useful magic number.
+It writes
+.bP
+the curses shared library major and minor versions
+as the first two bytes (e.g., 7 and 1),
+.bP
+followed by a binary dump of the \fBWINDOW\fP,
+.bP
+some data for wide-characters referenced by the \fBWINDOW\fP structure, and
+.bP
+finally, lines as done by other implementations.
+.SH EXAMPLE
+.PP
+Given a simple program which writes text to the screen
+(and for the sake of example, limiting the screen-size to 10x20):
+.NS
+#include <curses.h>
+
+int
+main(void)

+.SH NAME
+\fB@TABS@\fP \- set tabs on a terminal
+.SH SYNOPSIS
+\fB@TABS@\fP [\fIoptions\fP]] \fI[tabstop-list]\fP
+.SH DESCRIPTION
+.PP
+The \fB@TABS@\fP program clears and sets tab-stops on the terminal.
+This uses the terminfo \fBclear_all_tabs\fP and \fBset_tab\fP capabilities.
+If either is absent, \fB@TABS@\fP is unable to clear/set tab-stops.
+The terminal should be configured to use hard tabs, e.g.,
+.NS
+stty tab0
+.NE
+.PP
+Like \fB@CLEAR@\fP(1), \fB@TABS@\fP writes to the standard output.
+You can redirect the standard output to a file (which prevents
+\fB@TABS@\fP from actually changing the tabstops),
+and later \fBcat\fP the file to the screen, setting tabstops at that point.
+.PP
+These are hardware tabs, which cannot be queried rapidly by applications
+running in the terminal, if at all.
+Curses and other full-screen applications may use hardware tabs
+in optimizing their output to the terminal.
+If the hardware tabstops differ from the information in the terminal
+database, the result is unpredictable.
+Before running curses programs,
+you should either reset tab-stops to the standard interval
+.NS
+tabs -8
+.NE
+.PP
+or use the \fB@RESET@\fP program,
+since the normal initialization sequences do not ensure that tab-stops
+are reset.
+.SH OPTIONS
+.SS General Options
+.TP 5
+.BI \-T "name"
+Tell \fB@TABS@\fP which terminal type to use.
+If this option is not given, \fB@TABS@\fP will use the \fB$TERM\fP
+environment variable.
+If that is not set, it will use the \fIansi+tabs\fP entry.
+.TP 5
+.B \-d
+The debugging option shows a ruler line, followed by two data lines.
+The first data line shows the expected tab-stops marked with asterisks.
+The second data line shows the actual tab-stops, marked with asterisks.
+.TP 5
+.B \-n
+This option tells \fB@TABS@\fP to check the options and run any debugging
+option, but not to modify the terminal settings.
+.TP
+\fB\-V\fP
+reports the version of ncurses which was used in this program, and exits.
+.PP
+The \fB@TABS@\fP program processes a single list of tab stops.
+The last option to be processed which defines a list is the one that
+determines the list to be processed.
+.SS Implicit Lists
+Use a single number as an option,
+e.g., \*(``\fB\-5\fP\*('' to set tabs at the given
+interval (in this case 1, 6, 11, 16, 21, etc.).
+Tabs are repeated up to the right margin of the screen.
+.PP
+Use \*(``\fB\-0\fP\*('' to clear all tabs.
+.PP
+Use \*(``\fB\-8\fP\*('' to set tabs to the standard interval.
+.SS Explicit Lists
+An explicit list can be defined after the options
+(this does not use a \*(``\-\*('').
+The values in the list must be in increasing numeric order,
+and greater than zero.
+They are separated by a comma or a blank, for example,
+.NS
+tabs 1,6,11,16,21
+.br
+tabs 1 6 11 16 21
+.NE
+.PP
+Use a \*(``+\*('' to treat a number
+as an increment relative to the previous value,
+e.g.,
+.NS
+tabs 1,+5,+5,+5,+5
+.NE
+.PP
+which is equivalent to the 1,6,11,16,21 example.
+.SS Predefined Tab-Stops
+POSIX defines several predefined lists of tab stops.

+.SS Margins
+A few terminals provide the capability for changing their left/right margins.
+The @TABS@ program has an option to use this feature:
+.TP 5
+.BI +m \ margin
+The effect depends on whether the terminal has the margin capabilities:
+.RS
+.bP
+If the terminal provides the capability for setting the left margin,
+@TABS@ uses this, and adjusts the available width for tab-stops.
+.bP
+If the terminal does not provide the margin capabilities,
+@TABS@ imitates the effect, putting the tab stops at the appropriate
+place on each line.
+The terminal's left-margin is not modified.
+.RE
+.IP
+If the \fImargin\fP parameter is omitted, the default is 10.
+Use \fB+m0\fP to reset the left margin,
+i.e., to the left edge of the terminal's display.
+Before setting a left-margin,
+@TABS@ resets the margin to reduce problems which might arise
+on moving the cursor before the current left-margin.
+.PP
+When setting or resetting the left-margin,
+@TABS@ may reset the right-margin.
+.SH PORTABILITY
+.PP
+\fIIEEE Std 1003.1/The Open Group Base Specifications Issue 7\fP (POSIX.1-2008)
+describes a \fBtabs\fP utility.
+However
+.bP
+This standard describes a \fB+m\fP option, to set a terminal's left-margin.
+Very few of the entries in the terminal database provide the
+\fBsmgl\fP (\fBset_left_margin\fP) or
+\fBsmglp\fP (\fBset_left_margin_parm\fP)
+capability needed to support the feature.
+.bP
+There is no counterpart in X/Open Curses Issue 7 for this utility,
+unlike \fB@TPUT@\fP(1).
+.PP
+The \fB\-d\fP (debug) and \fB\-n\fP (no-op) options are extensions not provided
+by other implementations.
+.PP
+A \fBtabs\fP utility appeared in PWB/Unix 1.0 (1977).
+There was a reduced version of the \fBtabs\fP utility
+in Unix 7th edition and in 3BSD (1979).
+The latter supported a single \*(``\-n\*('' option
+(to cause the first tab stop to be set on the left margin).
+That option is not documented by POSIX.
+.PP
+The PWB/Unix \fBtabs\fP utility, which was included in System III (1980),
+used built-in tables rather than the terminal database,
+to support a half-dozen hardcopy terminal (printer) types.
+It also had built-in logic to support the left-margin,
+as well as a feature for copying the tab settings from a file.
+.PP
+Later versions of Unix, e.g., SVr4,
+added support for the terminal database,
+but kept the tables to support the printers.
+In an earlier development effort,
+the tab-stop initialization provided by \fBtset\fP (1982)
+and incorporated into \fBtput\fP uses the terminal database,
+.PP
+The \fB+m\fP option was documented
+in the Base Specifications Issue 5 (Unix98, 1997),
+and omitted in Issue 6 (Unix03, 2004) without documenting the rationale,
+though an introductory comment
+\fI\*(``and optionally adjusts the margin\*(''\fP remains,
+overlooked in the removal.
+The documented \fBtabs\fP utility in Issues 6 and later has no mechanism
+for setting margins.
+The \fB+m\fP option in this implementation differs from the feature
+in SVr4 by using terminal capabilities rather than built-in tables.
+.PP
+POSIX documents no limits on the number of tab stops.
+Documentation for other implementations states that there is a limit on the
+number of tab stops
+(e.g., 20 in PWB/Unix's \fBtabs\fP utility).
+While some terminals may not accept an arbitrary number
+of tab stops, this implementation will attempt to set tab stops up to the
+right margin of the screen, if the given list happens to be that long.
+.PP
+The \fIRationale\fP section of the POSIX documentation goes into some
+detail about the ways the committee considered redesigning the
+\fBtabs\fP and \fBtput\fP utilities,
+without proposing an improved solution.
+It comments that
+.RS 5
+.PP
+no known historical version of tabs supports the capability of setting
+arbitrary tab stops.
+.RE
+.PP
+However, the \fIExplicit Lists\fP described in this manual page
+were implemented in PWB/Unix.
+Those provide the capability of setting abitrary tab stops.

+.SH NAME
+term \- format of compiled term file.
+.SH SYNOPSIS
+.B term
+.SH DESCRIPTION
+.SS STORAGE LOCATION
+Compiled terminfo descriptions are placed under the directory \fB\*d\fP.
+Two configurations are supported (when building the \fBncurses\fP libraries):
+.TP 5
+.B directory tree
+A two-level scheme is used to avoid a linear search
+of a huge \s-1UNIX\s+1 system directory: \fB\*d/c/name\fP where
+.I name
+is the name of the terminal, and
+.I c
+is the first character of
+.IR name .
+Thus,
+.I act4
+can be found in the file \fB\*d/a/act4\fP.
+Synonyms for the same terminal are implemented by multiple
+links to the same compiled file.
+.TP 5
+.B hashed database
+Using Berkeley database, two types of records are stored:
+the terminfo data in the same format as stored in a directory tree with
+the terminfo's primary name as a key,
+and records containing only aliases pointing to the primary name.
+.IP
+If built to write hashed databases,
+\fBncurses\fP can still read terminfo databases organized as a directory tree,
+but cannot write entries into the directory tree.
+It can write (or rewrite) entries in the hashed database.
+.IP
+\fBncurses\fP distinguishes the two cases in the TERMINFO and TERMINFO_DIRS
+environment variable by assuming a directory tree for entries that
+correspond to an existing directory,
+and hashed database otherwise.
+.SS LEGACY STORAGE FORMAT
+The format has been chosen so that it will be the same on all hardware.
+An 8 or more bit byte is assumed, but no assumptions about byte ordering
+or sign extension are made.
+.PP
+The compiled file is created with the \fB@TIC@\fP program,
+and read by the routine \fBsetupterm\fP(3X).
+The file is divided into six parts:
+.RS 5
+.TP 3
+a) \fIheader\fP,
+.TP 3
+b) \fIterminal names\fP,
+.TP 3
+c) \fIboolean flags\fP,
+.TP 3
+d) \fInumbers\fP,
+.TP 3
+e) \fIstrings\fP, and
+.TP 3
+f) \fIstring table\fP.
+.RE
+.PP
+The \fIheader\fP section begins the file.
+This section contains six short integers in the format
+described below.
+These integers are
+.RS 5
+.TP 5
+(1) the \fImagic number\fP (octal 0432);
+.TP 5
+(2) the size, in bytes, of the \fIterminal names\fP section;
+.TP 5
+(3) the number of bytes in the \fIboolean flags\fP section;
+.TP 5
+(4) the number of short integers in the \fInumbers\fP section;
+.TP 5
+(5) the number of offsets (short integers) in the \fIstrings\fP section;
+.TP 5
+(6) the size, in bytes, of the \fIstring table\fP.
+.RE
+.PP
+The capabilities in the
+\fIboolean flags\fP,
+\fInumbers\fP, and
+\fIstrings\fP
+sections are in the same order as the file <term.h>.
+.PP
+Short integers are signed, in the range \-32768 to 32767.
+They are stored as two 8-bit bytes.
+The first byte contains the least significant 8 bits of the value,
+and the second byte contains the most significant 8 bits.
+(Thus, the value represented is 256*second+first.)
+This format corresponds to the hardware of the \s-1VAX\s+1
+and \s-1PDP\s+1-11 (that is, little-endian machines).
+Machines where this does not correspond to the hardware must read the
+integers as two bytes and compute the little-endian value.
+.PP
+Numbers in a terminal description,
+whether they are entries in the \fInumbers\fP or \fIstrings\fP table,
+are positive integers.
+Boolean flags are treated as positive one-byte integers.
+In each case, those positive integers represent a terminal capability.
+The terminal compiler @TIC@ uses negative integers to handle the cases where
+a capability is not available:
+.bP
+If a capability is absent from this terminal,
+@TIC@ stores a \-1 in the corresponding table.
+.IP
+The integer value \-1 is represented by two bytes 0377, 0377.
+.br
+Absent boolean values are represented by the byte 0 (false).
+.bP
+If a capability has been canceled from this terminal,
+@TIC@ stores a \-2 in the corresponding table.
+.IP
+The integer value \-2 is represented by two bytes 0377, 0376.
+.br
+The boolean value \-2 is represented by the byte 0376.
+.br
+.bP
+Other negative values are illegal.
+.PP
+The \fIterminal names\fP section comes after the \fIheader\fP.
+It contains the first line of the terminfo description,
+listing the various names for the terminal,
+separated by the \*(``|\*('' character.
+The \fIterminal names\fP section is terminated
+with an \s-1ASCII NUL\s+1 character.
+.PP
+The \fIboolean flags\fP section has one byte for each flag.
+Boolean capabilities are either 1 or 0 (true or false)
+according to whether the terminal supports the given capability or not.
+.PP
+Between the \fIboolean flags\fP section and the \fInumber\fP section,
+a null byte will be inserted, if necessary,
+to ensure that the \fInumber\fP section begins on an even byte
+This is a relic of the PDP\-11's word-addressed architecture,
+originally designed to avoid traps induced
+by addressing a word on an odd byte boundary.
+All short integers are aligned on a short word boundary.
+.PP
+The \fInumbers\fP section is similar to the \fIboolean flags\fP section.
+Each capability takes up two bytes,
+and is stored as a little-endian short integer.
+.PP
+The \fIstrings\fP section is also similar.
+Each capability is stored as a short integer.
+The capability value is an index into the \fIstring table\fP.
+.PP
+The \fIstring table\fP is the last section.
+It contains all of the values of string capabilities referenced in
+the \fIstrings\fP section.
+Each string is null-terminated.
+Special characters in ^X or \ec notation are stored in their
+interpreted form, not the printing representation.
+Padding information $<nn> and parameter information %x are
+stored intact in uninterpreted form.
+.SS EXTENDED STORAGE FORMAT
+The previous section describes the conventional terminfo binary format.
+With some minor variations of the offsets (see PORTABILITY),
+the same binary format is used in all modern UNIX systems.
+Each system uses a predefined set of boolean, number or string capabilities.
+.PP
+The \fBncurses\fP libraries and applications support
+extended terminfo binary format,
+allowing users to define capabilities which are loaded at runtime.
+This
+extension is made possible by using the fact that the other implementations
+stop reading the terminfo data when they have reached the end of the size given
+in the header.
+\fBncurses\fP checks the size,
+and if it exceeds that due to the predefined data,
+continues to parse according to its own scheme.
+.PP
+First, it reads the extended header (5 short integers):
+.RS 5
+.TP 5
+(1)
+count of extended boolean capabilities
+.TP 5
+(2)
+count of extended numeric capabilities
+.TP 5
+(3)
+count of extended string capabilities
+.TP 5
+(4)
+count of the items in extended string table
+.TP 5
+(5)
+size of the extended string table in bytes
+.RE
+.PP
+The count- and size-values for the extended string table
+include the extended capability \fInames\fP as well as
+extended capability \fIvalues\fP.
+.PP
+Using the counts and sizes, \fBncurses\fP allocates arrays and reads data
+for the extended capabilities in the same order as the header information.
+.PP
+The extended string table contains values for string capabilities.
+After the end of these values, it contains the names for each of
+the extended capabilities in order, e.g., booleans, then numbers and
+finally strings.
+.PP
+Applications which manipulate terminal data can use the definitions
+described in \fBterm_variables\fP(3X) which associate the long capability
+names with members of a \fBTERMTYPE\fP structure.
+.
+.SS EXTENDED NUMBER FORMAT
+.PP
+On occasion, 16-bit signed integers are not large enough.
+With \fBncurses\fP 6.1, a new format was introduced by making a few changes
+to the legacy format:
+.bP
+a different magic number (octal 01036)
+.bP
+changing the type for the \fInumber\fP array from signed 16-bit integers
+to signed 32-bit integers.
+.PP
+To maintain compatibility, the library presents the same data structures
+to direct users of the \fBTERMTYPE\fP structure as in previous formats.
+However, that cannot provide callers with the extended numbers.
+The library uses a similar but hidden data structure \fBTERMTYPE2\fP
+to provide data for the terminfo functions.
+.SH PORTABILITY
+.SS setupterm
+.PP
+Note that it is possible for
+.B setupterm
+to expect a different set of capabilities
+than are actually present in the file.
+Either the database may have been updated since
+.B setupterm
+was recompiled
+(resulting in extra unrecognized entries in the file)
+or the program may have been recompiled more recently
+than the database was updated
+(resulting in missing entries).
+The routine
+.B setupterm
+must be prepared for both possibilities \-
+this is why the numbers and sizes are included.
+Also, new capabilities must always be added at the end of the lists
+of boolean, number, and string capabilities.
+.SS Binary format
+.PP
+X/Open Curses does not specify a format for the terminfo database.
+UNIX System V curses used a directory-tree of binary files,
+one per terminal description.
+.PP
+Despite the consistent use of little-endian for numbers and the otherwise
+self-describing format, it is not wise to count on portability of binary
+terminfo entries between commercial UNIX versions.
+The problem is that there
+are at least three versions of terminfo (under HP\-UX, AIX, and OSF/1) which
+diverged from System V terminfo after SVr1, and have added extension
+capabilities to the string table that (in the binary format) collide with
+System V and XSI Curses extensions.
+See \fBterminfo\fP(\*n) for detailed
+discussion of terminfo source compatibility issues.
+.PP
+This implementation is by default compatible with the binary
+terminfo format used by Solaris curses,
+except in a few less-used details
+where it was found that the latter did not match X/Open Curses.
+The format used by the other Unix versions
+can be matched by building ncurses
+with different configuration options.
+.SS Magic codes
+.PP
+The magic number in a binary terminfo file is the first 16-bits (two bytes).
+Besides making it more reliable for the library to check that a file
+is terminfo,
+utilities such as \fBfile\fP(1) also use that to tell what the file-format is.
+System V defined more than one magic number,
+with 0433, 0435 as screen-dumps (see \fBscr_dump\fP(5)).
+This implementation uses 01036 as a continuation of that sequence,
+but with a different high-order byte to avoid confusion.
+.SS The TERMTYPE structure
+.PP
+Direct access to the \fBTERMTYPE\fP structure is provided for legacy
+applications.
+Portable applications should use the \fBtigetflag\fP and related functions
+described in \fBcurs_terminfo\fP(3X) for reading terminal capabilities.
+.SS Mixed-case terminal names
+.PP
+A small number of terminal descriptions use uppercase characters in
+their names.
+If the underlying filesystem ignores the difference between
+uppercase and lowercase,
+\fBncurses\fP represents the \*(``first character\*(''
+of the terminal name used as
+the intermediate level of a directory tree in (two-character) hexadecimal form.
+.SH EXAMPLE
+As an example, here is a description for the Lear-Siegler
+ADM\-3, a popular though rather stupid early terminal:
+.NS
+adm3a|lsi adm3a,
+        am,
+        cols#80, lines#24,
+        bel=^G, clear=\032$<1>, cr=^M, cub1=^H, cud1=^J,
+        cuf1=^L, cup=\\E=%p1%{32}%+%c%p2%{32}%+%c, cuu1=^K,
+        home=^^, ind=^J,
+.NS
+.PP
+and a hexadecimal dump of the compiled terminal description:

+term \- conventions for naming terminal types
+.SH DESCRIPTION
+.PP
+The environment variable \fBTERM\fP should normally contain the type name of
+the terminal, console or display-device type you are using.
+This information
+is critical for all screen-oriented programs, including your editor and mailer.
+.PP
+A default \fBTERM\fP value will be set on a per-line basis by either
+\fB/etc/inittab\fP (e.g., System\-V-like UNIXes)
+or \fB/etc/ttys\fP (BSD UNIXes).
+This will nearly always suffice for workstation and microcomputer consoles.
+.PP
+If you use a dialup line, the type of device attached to it may vary.
+Older UNIX systems pre-set a very dumb terminal type
+like \*(``dumb\*('' or \*(``dialup\*('' on dialup lines.
+Newer ones may pre-set \*(``vt100\*('', reflecting the prevalence of DEC
+VT100-compatible terminals and personal-computer emulators.
+.PP
+Modern telnets pass your \fBTERM\fP environment variable from the local side to
+the remote one.
+There can be problems if the remote terminfo or termcap entry
+for your type is not compatible with yours, but this situation is rare and
+can almost always be avoided by explicitly exporting \*(``vt100\*(''
+(assuming you are in fact using a VT100-superset console,
+terminal, or terminal emulator).
+.PP
+In any case, you are free to override the system \fBTERM\fP setting to your
+taste in your shell profile.
+The \fB@TSET@\fP(1) utility may be of assistance;
+you can give it a set of rules for deducing or requesting a terminal type based
+on the tty device and baud rate.
+.PP
+Setting your own \fBTERM\fP value may also be useful if you have created a
+custom entry incorporating options (such as visual bell or reverse-video)
+which you wish to override the system default type for your line.
+.PP
+Terminal type descriptions are stored as files of capability data underneath
+\*d.
+To browse a list of all terminal names recognized by the system, do
+.sp
+	@TOE@ | more
+.sp
+from your shell.
+These capability files are in a binary format optimized for
+retrieval speed (unlike the old text-based \fBtermcap\fP format they replace);
+to examine an entry, you must use the \fB@INFOCMP@\fP(1M) command.
+Invoke it as follows:
+.sp
+	@INFOCMP@ \fIentry_name\fP
+.sp
+where \fIentry_name\fP is the name of the type you wish to examine (and the
+name of its capability file the subdirectory of \*d named for its first
+letter).
+This command dumps a capability file in the text format described by
+\fBterminfo\fP(\*n).
+.PP
+The first line of a \fBterminfo\fP(\*n) description gives the names by which
+terminfo knows a terminal,
+separated by \*(``|\*('' (pipe-bar) characters with the last
+name field terminated by a comma.
+The first name field is the type's
+\fIprimary name\fP, and is the one to use when setting \fBTERM\fP.  The last
+name field (if distinct from the first) is actually a description of the
+terminal type (it may contain blanks; the others must be single words).
+Name
+fields between the first and last (if present) are aliases for the terminal,
+usually historical names retained for compatibility.
+.PP
+There are some conventions for how to choose terminal primary names that help
+keep them informative and unique.
+Here is a step-by-step guide to naming
+terminals that also explains how to parse them:
+.PP
+First, choose a root name.
+The root will consist of a lower-case letter
+followed by up to seven lower-case letters or digits.
+You need to avoid using
+punctuation characters in root names, because they are used and interpreted as
+filenames and shell meta-characters (such as !, $, *, ?, etc.) embedded in them
+may cause odd and unhelpful behavior.
+The slash (/), or any other character
+that may be interpreted by anyone's file system (\e, $, [, ]), is especially
+dangerous (terminfo is platform-independent, and choosing names with special
+characters could someday make life difficult for users of a future port).
+The
+dot (.) character is relatively safe as long as there is at most one per root
+name; some historical terminfo names use it.
+.PP
+The root name for a terminal or workstation console type should almost always
+begin with a vendor prefix (such as \fBhp\fP for Hewlett-Packard, \fBwy\fP for
+Wyse, or \fBatt\fP for AT&T terminals), or a common name of the terminal line
+(\fBvt\fP for the VT series of terminals from DEC, or \fBsun\fP for Sun
+Microsystems workstation consoles, or \fBregent\fP for the ADDS Regent series.
+You can list the terminfo tree to see what prefixes are already in common use.
+The root name prefix should be followed when appropriate by a model number;
+thus \fBvt100\fP, \fBhp2621\fP, \fBwy50\fP.
+.PP
+The root name for a PC-Unix console type should be the OS name,
+i.e., \fBlinux\fP, \fBbsdos\fP, \fBfreebsd\fP, \fBnetbsd\fP.  It should
+\fInot\fP be \fBconsole\fP or any other generic that might cause confusion in a
+multi-platform environment!  If a model number follows, it should indicate
+either the OS release level or the console driver release level.
+.PP
+The root name for a terminal emulator (assuming it does not fit one of the
+standard ANSI or vt100 types) should be the program name or a readily
+recognizable abbreviation of it (i.e., \fBversaterm\fP, \fBctrm\fP).
+.PP
+Following the root name, you may add any reasonable number of hyphen-separated
+feature suffixes.
+.TP 5
+2p
+Has two pages of memory.
+Likewise 4p, 8p, etc.
+.TP 5
+mc
+Magic-cookie.
+Some terminals (notably older Wyses) can only support one
+attribute without magic-cookie lossage.
+Their base entry is usually paired
+with another that has this suffix and uses magic cookies to support multiple
+attributes.
+.TP 5
+\-am
+Enable auto-margin (right-margin wraparound).
+.TP 5
+\-m
+Mono mode \- suppress color support.
+.TP 5
+\-na
+No arrow keys \- termcap ignores arrow keys which are actually there on the
+terminal, so the user can use the arrow keys locally.
+.TP 5
+\-nam
+No auto-margin \- suppress am capability.
+.TP 5
+\-nl
+No labels \- suppress soft labels.
+.TP 5
+\-nsl
+No status line \- suppress status line.
+.TP 5
+\-pp
+Has a printer port which is used.
+.TP 5
+\-rv
+Terminal in reverse video mode (black on white).
+.TP 5
+\-s
+Enable status line.
+.TP 5
+\-vb
+Use visible bell (flash) rather than beep.
+.TP 5
+\-w
+Wide; terminal is in 132-column mode.
+.PP
+Conventionally, if your terminal type is a variant intended to specify a
+line height, that suffix should go first.
+So, for a hypothetical FuBarCo
+model 2317 terminal in 30-line mode with reverse video, best form would be
+\fBfubar\-30\-rv\fP (rather than, say, \*(``fubar\-rv\-30\*('').
+.PP
+Terminal types that are written not as standalone entries, but rather as
+components to be plugged into other entries via \fBuse\fP capabilities,
+are distinguished by using embedded plus signs rather than dashes.
+.PP
+Commands which use a terminal type to control display often accept a \-T
+option that accepts a terminal name argument.
+Such programs should fall back
+on the \fBTERM\fP environment variable when no \-T option is specified.
+.SH PORTABILITY
+For maximum compatibility with older System V UNIXes, names and aliases
+should be unique within the first 14 characters.

+.SH DESCRIPTION
+This page summarizes variables provided by the \fBcurses\fP library's
+low-level terminfo interface.
+A more complete description is given in the \fBcurs_terminfo\fP(3X) manual page.
+.PP
+Depending on the configuration, these may be actual variables,
+or macros (see \fBcurs_threads\fP(3X))
+which provide read-only access to \fIcurses\fP's state.
+In either case, applications should treat them as read-only to avoid
+confusing the library.
+.SS Alternate Character Set Mapping
+After initializing the curses or terminfo interfaces,
+the \fBacs_map\fP array holds information used to translate cells
+with the \fBA_ALTCHARSET\fP video attribute into line-drawing characters.
+.PP
+The encoding of the information in this array has changed periodically.
+Application developers need only know that it is used for the \*(``ACS_\*(''
+constants in <curses.h>.
+.PP
+The comparable data for the wide-character library is a private variable.
+.SS Current Terminal Data
+After initializing the curses or terminfo interfaces,
+the \fBcur_term\fP contains data describing the current terminal.
+This variable is also set as a side-effect of \fBset_term\fP(3X)
+and \fBdelscreen\fP(3X).
+.PP
+It is possible to save a value of \fBcur_term\fP for subsequent
+use as a parameter to \fBset_term\fP, for switching between screens.
+Alternatively, one can save the return value from \fBnewterm\fP
+or \fBsetupterm\fP(3X) to reuse in \fBset_term\fP.
+.SS Terminfo Lookup Tables
+The \fB@TIC@\fP(1) and \fB@INFOCMP@\fP(1) programs use lookup tables for
+the long and short names of terminfo capabilities,
+as well as the corresponding names for termcap capabilities.
+These are available to other applications,
+although the hash-tables used by
+the terminfo and termcap functions are not available.
+.PP
+The long terminfo capability names use a \*(``l\*('' (ell) in their names:
+\fBboolfnames\fP,
+\fBnumfnames\fP, and
+\fBstrfnames\fP.
+.PP
+These are the short names for terminfo capabilities:
+\fBboolnames\fP,
+\fBnumnames\fP, and
+\fBstrnames\fP.
+.PP
+These are the corresponding names used for termcap descriptions:
+\fBboolcodes\fP,
+\fBnumcodes\fP, and
+\fBstrcodes\fP.
+.\"
+.SS Terminal Type
+A terminal description begins with one or more terminal names
+separated by \*(``|\*('' (vertical bars).
+On initialization of the curses or terminfo interfaces,
+\fBsetupterm\fP(3X) copies the terminal names to the array \fBttytype\fP.
+.\"
+.SS Terminfo Names
+.PP
+In addition to the variables, \fB<term.h>\fP also defines a symbol for each
+terminfo capability \fIlong name\fP.
+These are in terms of the symbol \fBCUR\fP,
+which is defined
+.PP
+.nf
+.ft CW
+#define CUR ((TERMTYPE *)(cur_term))->
+.fi
+.ft R
+.PP
+These symbols provide a faster method of accessing terminfo capabilities
+than using \fBtigetstr\fP(3X), etc.
+.PP
+The actual definition of \fBCUR\fP depends upon the implementation,
+but each terminfo library provides these long names defined to point
+into the current terminal description loaded into memory.
+.\"
+.SH NOTES
+The low-level terminfo interface is initialized using
+.hy 0
+\fBsetupterm\fP(3X).
+.hy
+The upper-level curses interface uses the low-level terminfo interface,
+internally.
+.\"
+.SH PORTABILITY
+X/Open Curses does not describe any of these except for \fBcur_term\fP.
+(The inclusion of \fBcur_term\fP appears to be an oversight,
+since other comparable low-level information is omitted by X/Open).
+.PP
+Other implementations may have comparable variables.
+Some implementations provide the variables in their libraries,
+but omit them from the header files.
+.PP
+All implementations which provide terminfo interfaces add definitions
+as described in the \fBTerminfo Names\fP section.
+Most, but not all, base the definition upon the \fBcur_term\fP variable.

+.SH NAME
+terminfo \- terminal capability database
+.SH SYNOPSIS
+\*d/*/*
+.SH DESCRIPTION
+.I Terminfo
+is a database describing terminals,
+used by screen-oriented programs such as
+\fBnvi\fP(1),
+\fBlynx\fP(1),
+\fBmutt\fP(1),
+and other curses applications,
+using high-level calls to libraries such as \fBcurses\fP(3X).
+It is also used via low-level calls by non-curses applications
+which may be screen-oriented (such as \fB@CLEAR@\fP(1))
+or non-screen (such as \fB@TABS@\fP(1)).
+.PP
+.I Terminfo
+describes terminals by giving a set of capabilities which they
+have, by specifying how to perform screen operations, and by
+specifying padding requirements and initialization sequences.
+.PP
+This manual describes \fBncurses\fP
+version @NCURSES_MAJOR@.@NCURSES_MINOR@ (patch @NCURSES_PATCH@).
+.SS Terminfo Entry Syntax
+.PP
+Entries in
+.I terminfo
+consist of a sequence of fields:
+.bP
+Each field ends with a comma \*(``,\*(''
+(embedded commas may be
+escaped with a backslash or written as \*(``\\054\*('').
+.bP
+White space between fields is ignored.
+.bP
+The first field in a \fIterminfo\fP entry begins in the first column.
+.bP
+Newlines and leading whitespace (spaces or tabs)
+may be used for formatting entries for readability.
+These are removed from parsed entries.
+.IP
+The \fB@INFOCMP@\fP \fB\-f\fP and \fB\-W\fP options rely on this to
+format if-then-else expressions,
+or to enforce maximum line-width.
+The resulting formatted terminal description can be read by \fB@TIC@\fP.
+.bP
+The first field for each terminal gives the names which are known for the
+terminal, separated by \*(``|\*('' characters.
+.IP
+The first name given is the most common abbreviation for the terminal
+(its primary name),
+the last name given should be a long name fully identifying the terminal
+(see \fBlongname\fP(3X)),
+and all others are treated as synonyms (aliases) for the primary terminal name.
+.IP
+X/Open Curses advises that all names but the last should be in lower case
+and contain no blanks;
+the last name may well contain upper case and blanks for readability.
+.IP
+This implementation is not so strict;
+it allows mixed case in the primary name and aliases.
+If the last name has no embedded blanks,
+it allows that to be both an alias and a verbose name
+(but will warn about this ambiguity).
+.bP
+Lines beginning with a \*(``#\*('' in the first column are treated as comments.
+.IP
+While comment lines are legal at any point, the output of \fB@CAPTOINFO@\fP
+and \fB@INFOTOCAP@\fP (aliases for \fB@TIC@\fP)
+will move comments so they occur only between entries.
+.PP
+Terminal names (except for the last, verbose entry) should
+be chosen using the following conventions.
+The particular piece of hardware making up the terminal should
+have a root name, thus \*(``hp2621\*(''.
+This name should not contain hyphens.
+Modes that the hardware can be in, or user preferences, should
+be indicated by appending a hyphen and a mode suffix.
+Thus, a vt100 in 132-column mode would be vt100\-w.
+The following suffixes should be used where possible:
+.PP
+.TS
+center ;
+l c l
+l l l.
+\fBSuffix	Meaning	Example\fP
+\-\fInn\fP	Number of lines on the screen	aaa\-60
+\-\fIn\fPp	Number of pages of memory	c100\-4p
+\-am	With automargins (usually the default)	vt100\-am
+\-m	Mono mode; suppress color       	ansi\-m
+\-mc	Magic cookie; spaces when highlighting	wy30\-mc
+\-na	No arrow keys (leave them in local)	c100\-na
+\-nam	Without automatic margins       	vt100\-nam
+\-nl	No status line                  	att4415\-nl
+\-ns	No status line                  	hp2626\-ns
+\-rv	Reverse video                   	c100\-rv
+\-s	Enable status line              	vt100\-s
+\-vb	Use visible bell instead of beep	wy370\-vb
+\-w	Wide mode (> 80 columns, usually 132)	vt100\-w
+.TE
+.PP
+For more on terminal naming conventions, see the \fBterm\fP(7) manual page.
+.SS Terminfo Capabilities Syntax
+.PP
+The terminfo entry consists of several \fIcapabilities\fP,
+i.e., features that the terminal has,
+or methods for exercising the terminal's features.
+.PP
+After the first field (giving the name(s) of the terminal entry),
+there should be one or more \fIcapability\fP fields.
+These are boolean, numeric or string names with corresponding values:
+.bP
+Boolean capabilities are true when present, false when absent.
+There is no explicit value for boolean capabilities.
+.bP
+Numeric capabilities have a \*(``#\*('' following the name,
+then an unsigned decimal integer value.
+.bP
+String capabilities have a \*(``=\*('' following the name,
+then an string of characters making up the capability value.
+.IP
+String capabilities can be split into multiple lines,
+just as the fields comprising a terminal entry can be
+split into multiple lines.
+While blanks between fields are ignored,
+blanks embedded within a string value are retained,
+except for leading blanks on a line.
+.PP
+Any capability can be \fIcanceled\fP,
+i.e., suppressed from the terminal entry,
+by following its name with \*(``@\*(''
+rather than a capability value.
+.SS Similar Terminals
+.PP
+If there are two very similar terminals, one (the variant) can be defined as
+being just like the other (the base) with certain exceptions.
+In the
+definition of the variant, the string capability \fBuse\fP can be given with
+the name of the base terminal:
+.bP
+The capabilities given before
+.B use
+override those in the base type named by
+.BR use .
+.bP
+If there are multiple \fBuse\fP capabilities, they are merged in reverse order.
+That is, the rightmost \fBuse\fP reference is processed first, then the one to
+its left, and so forth.
+.bP
+Capabilities given explicitly in the entry override
+those brought in by \fBuse\fP references.
+.PP
+A capability can be canceled by placing \fBxx@\fP to the left of the
+use reference that imports it, where \fIxx\fP is the capability.
+For example, the entry
+.RS
+.PP
+2621\-nl, smkx@, rmkx@, use=2621,
+.RE
+.PP
+defines a 2621\-nl that does not have the \fBsmkx\fP or \fBrmkx\fP capabilities,
+and hence does not turn on the function key labels when in visual mode.
+This is useful for different modes for a terminal, or for different
+user preferences.
+.PP
+An entry included via \fBuse\fP can contain canceled capabilities,
+which have the same effect as if those cancels were inline in the
+using terminal entry.

+.SS User-Defined Capabilities
+.
+The preceding section listed the \fIpredefined\fP capabilities.
+They deal with some special features for terminals no longer
+(or possibly never) produced.
+Occasionally there are special features of newer terminals which
+are awkward or impossible to represent by reusing the predefined
+capabilities.
+.PP
+\fBncurses\fP addresses this limitation by allowing user-defined capabilities.
+The \fB@TIC@\fP and \fB@INFOCMP@\fP programs provide
+the \fB\-x\fP option for this purpose.
+When \fB\-x\fP is set,
+\fB@TIC@\fP treats unknown capabilities as user-defined.
+That is, if \fB@TIC@\fP encounters a capability name
+which it does not recognize,
+it infers its type (boolean, number or string) from the syntax
+and makes an extended table entry for that capability.
+The \fBuse_extended_names\fP(3X) function makes this information
+conditionally available to applications.
+The ncurses library provides the data leaving most of the behavior
+to applications:
+.bP
+User-defined capability strings whose name begins
+with \*(``k\*('' are treated as function keys.
+.bP
+The types (boolean, number, string) determined by \fB@TIC@\fP
+can be inferred by successful calls on \fBtigetflag\fP, etc.
+.bP
+If the capability name happens to be two characters,
+the capability is also available through the termcap interface.
+.PP
+While termcap is said to be extensible because it does not use a predefined set
+of capabilities,
+in practice it has been limited to the capabilities defined by
+terminfo implementations.
+As a rule,
+user-defined capabilities intended for use by termcap applications should
+be limited to booleans and numbers to avoid running past the 1023 byte
+limit assumed by termcap implementations and their applications.
+In particular, providing extended sets of function keys (past the 60
+numbered keys and the handful of special named keys) is best done using
+the longer names available using terminfo.
+.
+.SS A Sample Entry

+.PP
+Entries may continue onto multiple lines by placing white space at
+the beginning of each line except the first.
+Comments may be included on lines beginning with \*(``#\*(''.
+Capabilities in
+.I terminfo
+are of three types:
+.bP
+Boolean capabilities which indicate that the terminal has
+some particular feature,
+.bP
+numeric capabilities giving the size of the terminal
+or the size of particular delays, and
+.bP
+string
+capabilities, which give a sequence which can be used to perform particular
+terminal operations.
+.PP
+.SS Types of Capabilities
+.PP
+All capabilities have names.
+For instance, the fact that
+ANSI-standard terminals have
+.I "automatic margins"
+(i.e., an automatic return and line-feed
+when the end of a line is reached) is indicated by the capability \fBam\fP.
+Hence the description of ansi includes \fBam\fP.
+Numeric capabilities are followed by the character \*(``#\*('' and then a positive value.
+Thus \fBcols\fP, which indicates the number of columns the terminal has,
+gives the value \*(``80\*('' for ansi.
+Values for numeric capabilities may be specified in decimal, octal or hexadecimal,
+using the C programming language conventions (e.g., 255, 0377 and 0xff or 0xFF).
+.PP
+Finally, string valued capabilities, such as \fBel\fP (clear to end of line
+sequence) are given by the two-character code, an \*(``=\*('', and then a string
+ending at the next following \*(``,\*(''.
+.PP
+A number of escape sequences are provided in the string valued capabilities
+for easy encoding of characters there:
+.bP
+Both \fB\eE\fP and \fB\ee\fP
+map to an \s-1ESCAPE\s0 character,
+.bP
+\fB^x\fP maps to a control-x for any appropriate \fIx\fP, and
+.bP
+the sequences
+.RS 6
+.PP
+\fB\en\fP, \fB\el\fP, \fB\er\fP, \fB\et\fP, \fB\eb\fP, \fB\ef\fP, and \fB\es\fP
+.RE
+.IP
+produce
+.RS 6
+.PP
+\fInewline\fP, \fIline-feed\fP, \fIreturn\fP, \fItab\fP, \fIbackspace\fP, \fIform-feed\fP, and \fIspace\fP,
+.RE
+.IP
+respectively.
+.PP
+X/Open Curses does not say what \*(``appropriate \fIx\fP\*('' might be.
+In practice, that is a printable ASCII graphic character.
+The special case \*(``^?\*('' is interpreted as DEL (127).
+In all other cases, the character value is AND'd with 0x1f,
+mapping to ASCII control codes in the range 0 through 31.
+.PP
+Other escapes include
+.bP
+\fB\e^\fP for \fB^\fP,
+.bP
+\fB\e\e\fP for \fB\e\fP,
+.bP
+\fB\e\fP, for comma,
+.bP
+\fB\e:\fP for \fB:\fP,
+.bP
+and \fB\e0\fP for null.
+.IP
+\fB\e0\fP will produce \e200, which does not terminate a string but behaves
+as a null character on most terminals, providing CS7 is specified.
+See \fBstty\fP(1).
+.IP
+The reason for this quirk is to maintain binary compatibility of the
+compiled terminfo files with other implementations,
+e.g., the SVr4 systems, which document this.
+Compiled terminfo files use null-terminated strings, with no lengths.
+Modifying this would require a new binary format,
+which would not work with other implementations.
+.PP
+Finally, characters may be given as three octal digits after a \fB\e\fP.
+.PP
+A delay in milliseconds may appear anywhere in a string capability, enclosed in
+$<..> brackets, as in \fBel\fP=\eEK$<5>,
+and padding characters are supplied by \fBtputs\fP(3X)
+to provide this delay.
+.bP
+The delay must be a number with at most one decimal
+place of precision; it may be followed by suffixes \*(``*\*('' or \*(``/\*('' or both.
+.bP
+A \*(``*\*(''
+indicates that the padding required is proportional to the number of lines
+affected by the operation, and the amount given is the per-affected-unit
+padding required.
+(In the case of insert character, the factor is still the
+number of \fIlines\fP affected.)
+.IP
+Normally, padding is advisory if the device has the \fBxon\fP
+capability; it is used for cost computation but does not trigger delays.
+.bP
+A \*(``/\*(''
+suffix indicates that the padding is mandatory and forces a delay of the given
+number of milliseconds even on devices for which \fBxon\fP is present to
+indicate flow control.
+.PP
+Sometimes individual capabilities must be commented out.
+To do this, put a period before the capability name.
+For example, see the second
+.B ind
+in the example above.
+.br
+.ne 5
+.PP
+.SS Fetching Compiled Descriptions
+.PP
+The \fBncurses\fP library searches for terminal descriptions in several places.
+It uses only the first description found.
+The library has a compiled-in list of places to search
+which can be overridden by environment variables.
+Before starting to search,
+\fBncurses\fP eliminates duplicates in its search list.
+.bP
+If the environment variable TERMINFO is set, it is interpreted as the pathname
+of a directory containing the compiled description you are working on.
+Only that directory is searched.
+.bP
+If TERMINFO is not set,
+\fBncurses\fP will instead look in the directory \fB$HOME/.terminfo\fP
+for a compiled description.
+.bP
+Next, if the environment variable TERMINFO_DIRS is set,
+\fBncurses\fP will interpret the contents of that variable
+as a list of colon-separated directories (or database files) to be searched.
+.IP
+An empty directory name (i.e., if the variable begins or ends
+with a colon, or contains adjacent colons)
+is interpreted as the system location \fI\*d\fP.
+.bP
+Finally, \fBncurses\fP searches these compiled-in locations:
+.RS
+.bP
+a list of directories (@TERMINFO_DIRS@), and
+.bP
+the system terminfo directory, \fI\*d\fP (the compiled-in default).
+.RE
+.SS Preparing Descriptions
+.PP
+We now outline how to prepare descriptions of terminals.
+The most effective way to prepare a terminal description is by imitating
+the description of a similar terminal in
+.I terminfo
+and to build up a description gradually, using partial descriptions
+with
+.I vi
+or some other screen-oriented program to check that they are correct.
+Be aware that a very unusual terminal may expose deficiencies in
+the ability of the
+.I terminfo
+file to describe it
+or bugs in the screen-handling code of the test program.
+.PP
+To get the padding for insert line right (if the terminal manufacturer
+did not document it) a severe test is to edit a large file at 9600 baud,
+delete 16 or so lines from the middle of the screen, then hit the \*(``u\*(''
+key several times quickly.
+If the terminal messes up, more padding is usually needed.
+A similar test can be used for insert character.
+.PP
+.SS Basic Capabilities
+.PP
+The number of columns on each line for the terminal is given by the
+\fBcols\fP numeric capability.
+If the terminal is a \s-1CRT\s0, then the
+number of lines on the screen is given by the \fBlines\fP capability.
+If the terminal wraps around to the beginning of the next line when
+it reaches the right margin, then it should have the \fBam\fP capability.
+If the terminal can clear its screen, leaving the cursor in the home
+position, then this is given by the \fBclear\fP string capability.
+If the terminal overstrikes
+(rather than clearing a position when a character is struck over)
+then it should have the \fBos\fP capability.
+If the terminal is a printing terminal, with no soft copy unit,
+give it both
+.B hc
+and
+.BR os .
+.RB ( os
+applies to storage scope terminals, such as \s-1TEKTRONIX\s+1 4010
+series, as well as hard copy and APL terminals.)
+If there is a code to move the cursor to the left edge of the current
+row, give this as
+.BR cr .
+(Normally this will be carriage return, control/M.)
+If there is a code to produce an audible signal (bell, beep, etc)
+give this as
+.BR bel .
+.PP
+If there is a code to move the cursor one position to the left
+(such as backspace) that capability should be given as
+.BR cub1 .
+Similarly, codes to move to the right, up, and down should be
+given as
+.BR cuf1 ,
+.BR cuu1 ,
+and
+.BR cud1 .
+These local cursor motions should not alter the text they pass over,
+for example, you would not normally use \*(``\fBcuf1\fP=\ \*('' because the
+space would erase the character moved over.
+.PP
+A very important point here is that the local cursor motions encoded
+in
+.I terminfo
+are undefined at the left and top edges of a \s-1CRT\s0 terminal.
+Programs should never attempt to backspace around the left edge,
+unless
+.B bw
+is given,
+and never attempt to go up locally off the top.
+In order to scroll text up, a program will go to the bottom left corner
+of the screen and send the
+.B ind
+(index) string.
+.PP
+To scroll text down, a program goes to the top left corner
+of the screen and sends the
+.B ri
+(reverse index) string.
+The strings
+.B ind
+and
+.B ri
+are undefined when not on their respective corners of the screen.
+.PP
+Parameterized versions of the scrolling sequences are
+.B indn
+and
+.B rin
+which have the same semantics as
+.B ind
+and
+.B ri
+except that they take one parameter, and scroll that many lines.
+They are also undefined except at the appropriate edge of the screen.
+.PP
+The \fBam\fP capability tells whether the cursor sticks at the right
+edge of the screen when text is output, but this does not necessarily
+apply to a
+.B cuf1
+from the last column.
+The only local motion which is defined from the left edge is if
+.B bw
+is given, then a
+.B cub1
+from the left edge will move to the right edge of the previous row.
+If
+.B bw
+is not given, the effect is undefined.
+This is useful for drawing a box around the edge of the screen, for example.
+If the terminal has switch selectable automatic margins,
+the
+.I terminfo
+file usually assumes that this is on; i.e., \fBam\fP.
+If the terminal has a command which moves to the first column of the next
+line, that command can be given as
+.B nel
+(newline).
+It does not matter if the command clears the remainder of the current line,
+so if the terminal has no
+.B cr
+and
+.B lf
+it may still be possible to craft a working
+.B nel
+out of one or both of them.
+.PP
+These capabilities suffice to describe hard-copy and \*(``glass-tty\*('' terminals.
+Thus the model 33 teletype is described as

+.\".in +2
+.ft R
+.fi
+.PP
+.SS Parameterized Strings
+.PP
+Cursor addressing and other strings requiring parameters
+in the terminal are described by a
+parameterized string capability,
+with \fIprintf\fP-like escapes such as \fI%x\fP in it.
+For example, to address the cursor, the
+.B cup
+capability is given, using two parameters:
+the row and column to address to.
+(Rows and columns are numbered from zero and refer to the
+physical screen visible to the user, not to any unseen memory.)
+If the terminal has memory relative cursor addressing,
+that can be indicated by
+.BR mrcup .
+.PP
+The parameter mechanism uses a stack and special \fB%\fP codes
+to manipulate it.
+Typically a sequence will push one of the
+parameters onto the stack and then print it in some format.
+Print (e.g., \*(``%d\*('') is a special case.
+Other operations, including \*(``%t\*('' pop their operand from the stack.
+It is noted that more complex operations are often necessary,
+e.g., in the \fBsgr\fP string.
+.PP
+The \fB%\fP encodings have the following meanings:
+.PP
+.TP 5
+\fB%%\fP
+outputs \*(``%\*(''
+.TP
+\fB%\fP\fI[[\fP:\fI]flags][width[.precision]][\fP\fBdoxXs\fP\fI]\fP
+as in \fBprintf\fP(3), flags are \fI[\-+#]\fP and \fIspace\fP.
+Use a \*(``:\*('' to allow the next character to be a \*(``\-\*('' flag,
+avoiding interpreting \*(``%\-\*('' as an operator.
+.TP
+\f(CW%c\fP
+print \fIpop()\fP like %c in \fBprintf\fP

+\fB%P\fP\fI[A\-Z]\fP
+set static variable \fI[a\-z]\fP to \fIpop()\fP
+.TP
+\fB%g\fP\fI[A\-Z]\fP
+get static variable \fI[a\-z]\fP and push it
+.IP
+The terms \*(``static\*('' and \*(``dynamic\*('' are misleading.
+Historically, these are simply two different sets of variables,
+whose values are not reset between calls to \fBtparm\fP(3X).
+However, that fact is not documented in other implementations.
+Relying on it will adversely impact portability to other implementations:
+.RS
+.bP
+SVr2 curses supported \fIdynamic\fP variables.
+Those are set only by a \fB%P\fP operator.
+A \fB%g\fP for a given variable without first setting it with \fB%P\fP
+will give unpredictable results, because dynamic variables are
+an uninitialized local array on the stack in the \fBtparm\fP function.
+.bP
+SVr3.2 curses supported \fIstatic\fP variables.
+Those are an array in the \fBTERMINAL\fP
+structure (declared in \fBterm.h\fP),
+and are zeroed automatically when the \fBsetupterm\fP function
+allocates the data.
+.bP
+SVr4 curses made no further improvements
+to the \fIdynamic/static\fP variable feature.
+.bP
+Solaris XPG4 curses does not distinguish between \fIdynamic\fP and
+\fIstatic\fP variables.
+They are the same.
+Like SVr4 curses, XPG4 curses does not initialize these explicitly.
+.bP
+Before version 6.3, ncurses stores both \fIdynamic\fP and \fIstatic\fP

+relative cursor addressing, a one screen-sized window must be fixed into
+the terminal for cursor addressing to work properly.

+It is possible to get the effect of insert or delete line using

+(Note that the \fBncurses\fP(3X) library does this synthesis

+Yet another way to construct insert and delete might be to use a combination of

+Inserting lines at the top or bottom of the screen can also be

+System V and XSI Curses expect that \fBind\fP, \fBri\fP,
+\fBindn\fP, and \fBrin\fP will simulate destructive scrolling; their

+.PP
+.SS Insert/Delete Character
+.PP
+There are two basic kinds of intelligent terminals with respect to
+insert/delete character which can be described using
+.I terminfo.
+The most common insert/delete character operations affect only the characters
+on the current line and shift characters off the end of the line rigidly.
+Other terminals, such as the Concept 100 and the Perkin Elmer Owl, make
+a distinction between typed and untyped blanks on the screen, shifting
+upon an insert or delete only to an untyped blank on the screen which is
+either eliminated, or expanded to two untyped blanks.
+.PP
+You can determine the
+kind of terminal you have by clearing the screen and then typing
+text separated by cursor motions.
+Type \*(``abc\ \ \ \ def\*('' using local
+cursor motions (not spaces) between the \*(``abc\*('' and the \*(``def\*(''.
+Then position the cursor before the \*(``abc\*('' and put the terminal in insert
+mode.
+If typing characters causes the rest of the line to shift
+rigidly and characters to fall off the end, then your terminal does
+not distinguish between blanks and untyped positions.
+If the \*(``abc\*(''
+shifts over to the \*(``def\*('' which then move together around the end of the
+current line and onto the next as you insert, you have the second type of
+terminal, and should give the capability \fBin\fP, which stands for
+\*(``insert null\*(''.
+.PP
+While these are two logically separate attributes (one line versus multi-line
+insert mode, and special treatment of untyped spaces) we have seen no
+terminals whose insert mode cannot be described with the single attribute.
+.PP
+Terminfo can describe both terminals which have an insert mode, and terminals
+which send a simple sequence to open a blank position on the current line.
+Give as \fBsmir\fP the sequence to get into insert mode.
+Give as \fBrmir\fP the sequence to leave insert mode.
+Now give as \fBich1\fP any sequence needed to be sent just before sending
+the character to be inserted.
+Most terminals with a true insert mode
+will not give \fBich1\fP; terminals which send a sequence to open a screen
+position should give it here.
+.PP
+If your terminal has both, insert mode is usually preferable to \fBich1\fP.
+Technically, you should not give both unless the terminal actually requires
+both to be used in combination.
+Accordingly, some non-curses applications get
+confused if both are present; the symptom is doubled characters in an update
+using insert.
+This requirement is now rare; most \fBich\fP sequences do not
+require previous smir, and most smir insert modes do not require \fBich1\fP
+before each character.
+Therefore, the new \fBcurses\fP actually assumes this
+is the case and uses either \fBrmir\fP/\fBsmir\fP or \fBich\fP/\fBich1\fP as
+appropriate (but not both).
+If you have to write an entry to be used under
+new curses for a terminal old enough to need both, include the
+\fBrmir\fP/\fBsmir\fP sequences in \fBich1\fP.
+.PP
+If post insert padding is needed, give this as a number of milliseconds
+in \fBip\fP (a string option).
+Any other sequence which may need to be
+sent after an insert of a single character may also be given in \fBip\fP.
+If your terminal needs both to be placed into an \*(``insert mode\*('' and
+a special code to precede each inserted character, then both
+.BR smir / rmir
+and
+.B ich1
+can be given, and both will be used.
+The
+.B ich
+capability, with one parameter,
+.IR n ,
+will repeat the effects of
+.B ich1
+.I n
+times.
+.PP
+If padding is necessary between characters typed while not
+in insert mode, give this as a number of milliseconds padding in \fBrmp\fP.
+.PP
+It is occasionally necessary to move around while in insert mode
+to delete characters on the same line (e.g., if there is a tab after
+the insertion position).
+If your terminal allows motion while in
+insert mode you can give the capability \fBmir\fP to speed up inserting
+in this case.
+Omitting \fBmir\fP will affect only speed.
+Some terminals
+(notably Datamedia's) must not have \fBmir\fP because of the way their
+insert mode works.
+.PP
+Finally, you can specify
+.B dch1
+to delete a single character,
+.B dch
+with one parameter,
+.IR n ,
+to delete
+.I n characters,
+and delete mode by giving \fBsmdc\fP and \fBrmdc\fP
+to enter and exit delete mode (any mode the terminal needs to be placed
+in for
+.B dch1
+to work).
+.PP
+A command to erase
+.I n
+characters (equivalent to outputting

+blanks without moving the cursor)
+can be given as

+with one parameter.
+.PP
+.SS "Highlighting, Underlining, and Visible Bells"

+Note that it is not possible to handle
+terminals where the keypad only works in local (this applies, for example,
+to the unshifted HP 2621 keys).
+If the keypad can be set to transmit or not transmit,
+give these codes as \fBsmkx\fP and \fBrmkx\fP.
+Otherwise the keypad is assumed to always transmit.
+.PP
+The codes sent by the left arrow, right arrow, up arrow, down arrow,
+and home keys can be given as
+\fBkcub1, kcuf1, kcuu1, kcud1, \fRand\fB khome\fP respectively.
+If there are function keys such as f0, f1, ..., f10, the codes they send
+can be given as \fBkf0, kf1, ..., kf10\fP.
+If these keys have labels other than the default f0 through f10, the labels
+can be given as \fBlf0, lf1, ..., lf10\fP.
+.PP
+The codes transmitted by certain other special keys can be given:
+.bP
+.B kll
+(home down),
+.bP
+.B kbs
+(backspace),
+.bP
+.B ktbc
+(clear all tabs),
+.bP
+.B kctab
+(clear the tab stop in this column),
+.bP
+.B kclr
+(clear screen or erase key),
+.bP
+.B kdch1
+(delete character),
+.bP
+.B kdl1
+(delete line),
+.bP
+.B krmir
+(exit insert mode),
+.bP
+.B kel
+(clear to end of line),
+.bP
+.B ked
+(clear to end of screen),
+.bP
+.B kich1
+(insert character or enter insert mode),
+.bP
+.B kil1
+(insert line),
+.bP
+.B knp
+(next page),
+.bP
+.B kpp
+(previous page),
+.bP
+.B kind
+(scroll forward/down),
+.bP
+.B kri
+(scroll backward/up),
+.bP
+.B khts
+(set a tab stop in this column).
+.PP
+In addition, if the keypad has a 3 by 3 array of keys including the four
+arrow keys, the other five keys can be given as
+.BR ka1 ,
+.BR ka3 ,
+.BR kb2 ,
+.BR kc1 ,
+and
+.BR kc3 .
+These keys are useful when the effects of a 3 by 3 directional pad are needed.
+.PP
+Strings to program function keys can be given as
+.BR pfkey ,
+.BR pfloc ,
+and
+.BR pfx .
+A string to program screen labels should be specified as \fBpln\fP.
+Each of these strings takes two parameters: the function key number to
+program (from 0 to 10) and the string to program it with.
+Function key numbers out of this range may program undefined keys in
+a terminal dependent manner.
+The difference between the capabilities is that
+.B pfkey
+causes pressing the given key to be the same as the user typing the
+given string;
+.B pfloc
+causes the string to be executed by the terminal in local; and
+.B pfx
+causes the string to be transmitted to the computer.
+.PP
+The capabilities \fBnlab\fP, \fBlw\fP and \fBlh\fP
+define the number of programmable
+screen labels and their width and height.
+If there are commands to turn the labels on and off,
+give them in \fBsmln\fP and \fBrmln\fP.
+\fBsmln\fP is normally output after one or more pln
+sequences to make sure that the change becomes visible.
+.PP
+.SS Tabs and Initialization
+.PP
+A few capabilities are used only for tabs:
+.bP
+If the terminal has hardware tabs, the command to advance to the next
+tab stop can be given as
+.B ht
+(usually control/I).
+.bP
+A \*(``back-tab\*('' command which moves leftward to the preceding tab stop can
+be given as
+.BR cbt .
+.IP
+By convention, if the teletype modes indicate that tabs are being
+expanded by the computer rather than being sent to the terminal,
+programs should not use
+.B ht
+or
+.B cbt
+even if they are present, since the user may not have the tab stops
+properly set.
+.bP
+If the terminal has hardware tabs which are initially set every
+.I n
+spaces when the terminal is powered up,
+the numeric parameter
+.B it
+is given, showing the number of spaces the tabs are set to.
+.IP
+The \fBit\fP capability is normally used by the \fB@TSET@\fP
+command to determine whether to set the mode for hardware tab expansion,
+and whether to set the tab stops.
+If the terminal has tab stops that can be saved in non-volatile memory,
+the terminfo description can assume that they are properly set.
+.PP
+Other capabilities
+include
+.bP
+.BR is1 ,
+.BR is2 ,
+and
+.BR is3 ,
+initialization strings for the terminal,
+.bP
+.BR iprog ,
+the path name of a program to be run to initialize the terminal,
+.bP
+and \fBif\fP, the name of a file containing long initialization strings.
+.PP
+These strings are expected to set the terminal into modes consistent
+with the rest of the terminfo description.
+They are normally sent to the terminal, by the
+.I init
+option of the \fB@TPUT@\fP program, each time the user logs in.
+They will be printed in the following order:
+.RS
+.TP
+run the program
+.B iprog
+.TP
+output
+.br
+\fBis1\fP and
+.br
+\fBis2\fP
+.TP
+set the margins using
+\fBmgc\fP or
+.br
+\fBsmglp\fP and \fBsmgrp\fP or
+.br
+\fBsmgl\fP and \fBsmgr\fP
+.TP
+set tabs using
+.B tbc
+and
+.B hts
+.TP
+print the file
+\fBif\fP
+.TP
+and finally output
+\fBis3\fP.
+.RE
+.PP
+Most initialization is done with
+.BR is2 .
+Special terminal modes can be set up without duplicating strings
+by putting the common sequences in
+.B is2
+and special cases in
+.B is1
+and
+.BR is3 .
+.PP
+A set of sequences that does a harder reset from a totally unknown state
+can be given as
+.BR rs1 ,
+.BR rs2 ,
+.B rf
+and
+.BR rs3 ,
+analogous to
+.B is1 ,
+.B is2 ,
+.B if
+and
+.B is3
+respectively.
+These strings are output
+by \fIreset\fP option of \fB@TPUT@\fP,
+or by the \fB@RESET@\fP program
+(an alias of \fB@TSET@\fP),
+which is used when the terminal gets into a wedged state.
+Commands are normally placed in
+.BR rs1 ,
+.B rs2
+.B rs3
+and
+.B rf
+only if they produce annoying effects on the screen and are not
+necessary when logging in.
+For example, the command to set the vt100 into 80-column mode would
+normally be part of
+.BR is2 ,
+but it causes an annoying glitch of the screen and is not normally
+needed since the terminal is usually already in 80-column mode.
+.PP
+The \fB@RESET@\fP program writes strings including
+.BR iprog ,
+etc., in the same order as the
+.I init
+program, using
+.BR rs1 ,
+etc., instead of
+.BR is1 ,
+etc.
+If any of
+.BR rs1 ,
+.BR rs2 ,
+.BR rs3 ,
+or
+.B rf
+reset capability strings are missing,
+the \fB@RESET@\fP program
+falls back upon the corresponding initialization capability string.
+.PP
+If there are commands to set and clear tab stops, they can be given as
+.B tbc
+(clear all tab stops)
+and
+.B hts
+(set a tab stop in the current column of every row).
+If a more complex sequence is needed to set the tabs than can be
+described by this, the sequence can be placed in
+.B is2
+or
+.BR if .
+.PP
+The \fB@TPUT@ reset\fP command uses the same capability strings
+as the \fB@RESET@\fP command,
+although the two programs (\fB@TPUT@\fP and \fB@RESET@\fP)
+provide different command-line options.
+.PP
+In practice, these terminfo capabilities are not often used in
+initialization of tabs
+(though they are required for the \fB@TABS@\fP program):
+.bP
+Almost all hardware terminals (at least those which supported tabs)
+initialized those to every \fIeight\fP columns:
+.IP
+The only exception was the AT&T 2300 series,
+which set tabs to every \fIfive\fP columns.
+.bP
+In particular, developers of the hardware terminals which are commonly used
+as models for modern terminal emulators provided documentation demonstrating
+that \fIeight\fP columns were the standard.
+.bP
+Because of this, the terminal initialization programs
+\fB@TPUT@\fP and \fB@TSET@\fP
+use the
+\fBtbc\fP (\fBclear_all_tabs\fP) and
+\fBhts\fP (\fBset_tab\fP) capabilities directly
+only when the \fBit\fP (\fBinit_tabs\fP) capability
+is set to a value other than \fIeight\fP.
+.SS Delays and Padding
+.PP
+Many older and slower terminals do not support either XON/XOFF or DTR
+handshaking, including hard copy terminals and some very archaic CRTs
+(including, for example, DEC VT100s).
+These may require padding characters
+after certain cursor motions and screen changes.
+.PP
+If the terminal uses xon/xoff handshaking for flow control (that is,
+it automatically emits ^S back to the host when its input buffers are
+close to full), set
+.BR xon .
+This capability suppresses the emission of padding.
+You can also set it
+for memory-mapped console devices effectively that do not have a speed limit.
+Padding information should still be included so that routines can
+make better decisions about relative costs, but actual pad characters will
+not be transmitted.
+.PP
+If \fBpb\fP (padding baud rate) is given, padding is suppressed at baud rates
+below the value of \fBpb\fP.
+If the entry has no padding baud rate, then
+whether padding is emitted or not is completely controlled by \fBxon\fP.
+.PP
+If the terminal requires other than a null (zero) character as a pad,
+then this can be given as \fBpad\fP.
+Only the first character of the
+.B pad
+string is used.
+.PP
+.SS Status Lines
+Some terminals have an extra \*(``status line\*('' which is not normally used by
+software (and thus not counted in the terminal's \fBlines\fP capability).
+.PP
+The simplest case is a status line which is cursor-addressable but not
+part of the main scrolling region on the screen; the Heathkit H19 has
+a status line of this kind, as would a 24-line VT100 with a 23-line
+scrolling region set up on initialization.
+This situation is indicated
+by the \fBhs\fP capability.
+.PP
+Some terminals with status lines need special sequences to access the
+status line.
+These may be expressed as a string with single parameter
+\fBtsl\fP which takes the cursor to a given zero-origin column on the
+status line.
+The capability \fBfsl\fP must return to the main-screen
+cursor positions before the last \fBtsl\fP.
+You may need to embed the
+string values of \fBsc\fP (save cursor) and \fBrc\fP (restore cursor)
+in \fBtsl\fP and \fBfsl\fP to accomplish this.
+.PP
+The status line is normally assumed to be the same width as the width
+of the terminal.
+If this is untrue, you can specify it with the numeric
+capability \fBwsl\fP.
+.PP
+A command to erase or blank the status line may be specified as \fBdsl\fP.
+.PP
+The boolean capability \fBeslok\fP specifies that escape sequences, tabs,
+etc., work ordinarily in the status line.
+.PP
+The \fBncurses\fP implementation does not yet use any of these capabilities.
+They are documented here in case they ever become important.
+.PP
+.SS Line Graphics
+.PP
+Many terminals have alternate character sets useful for forms-drawing.
+Terminfo and \fBcurses\fP have built-in support
+for most of the drawing characters
+supported by the VT100, with some characters from the AT&T 4410v1 added.
+This alternate character set may be specified by the \fBacsc\fP capability.

+A few notes apply to the table itself:
+.bP
+X/Open Curses incorrectly states that the mapping for \fIlantern\fP is
+uppercase \*(``I\*('' although Unix implementations use the
+lowercase \*(``i\*('' mapping.
+.bP
+The DEC VT100 implemented graphics using the alternate character set
+feature, temporarily switching \fImodes\fP and sending characters
+in the range 0x60 (96) to 0x7e (126)
+(the \fBacsc Value\fP column in the table).
+.bP
+The AT&T terminal added graphics characters outside that range.
+.IP
+Some of the characters within the range do not match the VT100;
+presumably they were used in the AT&T terminal:
+\fIboard of squares\fP replaces the VT100 \fInewline\fP symbol, while
+\fIlantern symbol\fP replaces the VT100 \fIvertical tab\fP symbol.
+The other VT100 symbols for control characters (\fIhorizontal tab\fP,
+\fIcarriage return\fP and \fIline-feed\fP) are not (re)used in curses.
+.PP
+The best way to define a new device's graphics set is to add a column
+to a copy of this table for your terminal, giving the character which
+(when emitted between \fBsmacs\fP/\fBrmacs\fP switches) will be rendered
+as the corresponding graphic.
+Then read off the VT100/your terminal
+character pairs right to left in sequence; these become the ACSC string.
+.PP
+.SS Color Handling
+.PP
+The curses library functions \fBinit_pair\fP and \fBinit_color\fP
+manipulate the \fIcolor pairs\fP and \fIcolor values\fP discussed in this
+section
+(see \fBcurs_color\fP(3X) for details on these and related functions).
+.PP
+Most color terminals are either \*(``Tektronix-like\*('' or \*(``HP-like\*('':
+.bP
+Tektronix-like
+terminals have a predefined set of \fIN\fP colors
+(where \fIN\fP is usually 8),
+and can set
+character-cell foreground and background characters independently, mixing them
+into \fIN\fP\ *\ \fIN\fP color-pairs.
+.bP
+On HP-like terminals, the user must set each color
+pair up separately (foreground and background are not independently settable).
+Up to \fIM\fP color-pairs may be set up from 2*\fIM\fP different colors.
+ANSI-compatible terminals are Tektronix-like.
+.PP
+Some basic color capabilities are independent of the color method.
+The numeric
+capabilities \fBcolors\fP and \fBpairs\fP specify the maximum numbers of colors
+and color-pairs that can be displayed simultaneously.
+The \fBop\fP (original
+pair) string resets foreground and background colors to their default values
+for the terminal.
+The \fBoc\fP string resets all colors or color-pairs to
+their default values for the terminal.
+Some terminals (including many PC
+terminal emulators) erase screen areas with the current background color rather
+than the power-up default background; these should have the boolean capability
+\fBbce\fP.
+.PP
+While the curses library works with \fIcolor pairs\fP
+(reflecting the inability of some devices to set foreground
+and background colors independently),
+there are separate capabilities for setting these features:
+.bP
+To change the current foreground or background color on a Tektronix-type
+terminal, use \fBsetaf\fP (set ANSI foreground) and \fBsetab\fP (set ANSI
+background) or \fBsetf\fP (set foreground) and \fBsetb\fP (set background).
+These take one parameter, the color number.
+The SVr4 documentation describes
+only \fBsetaf\fP/\fBsetab\fP; the XPG4 draft says that "If the terminal
+supports ANSI escape sequences to set background and foreground, they should
+be coded as \fBsetaf\fP and \fBsetab\fP, respectively.
+.bP
+If the terminal
+supports other escape sequences to set background and foreground, they should
+be coded as \fBsetf\fP and \fBsetb\fP, respectively.
+The \fBvidputs\fP and the \fBrefresh\fP(3X) functions
+use the \fBsetaf\fP and \fBsetab\fP capabilities if they are defined.
+.PP
+The \fBsetaf\fP/\fBsetab\fP and \fBsetf\fP/\fBsetb\fP capabilities take a
+single numeric argument each.
+Argument values 0-7 of \fBsetaf\fP/\fBsetab\fP are portably defined as
+follows (the middle column is the symbolic #define available in the header for
+the \fBcurses\fP or \fBncurses\fP libraries).
+The terminal hardware is free to
+map these as it likes, but the RGB values indicate normal locations in color
+space.

+It is important to not confuse the two sets of color capabilities;
+otherwise red/blue will be interchanged on the display.
+.PP
+On an HP-like terminal, use \fBscp\fP with a color-pair number parameter to set
+which color pair is current.
+.PP
+Some terminals allow the \fIcolor values\fP to be modified:
+.bP
+On a Tektronix-like terminal, the capability \fBccc\fP may be present to
+indicate that colors can be modified.
+If so, the \fBinitc\fP capability will
+take a color number (0 to \fBcolors\fP \- 1)and three more parameters which
+describe the color.
+These three parameters default to being interpreted as RGB
+(Red, Green, Blue) values.
+If the boolean capability \fBhls\fP is present,
+they are instead as HLS (Hue, Lightness, Saturation) indices.
+The ranges are
+terminal-dependent.
+.bP
+On an HP-like terminal, \fBinitp\fP may give a capability for changing a
+color-pair value.
+It will take seven parameters; a color-pair number (0 to
+\fBmax_pairs\fP \- 1), and two triples describing first background and then
+foreground colors.
+These parameters must be (Red, Green, Blue) or
+(Hue, Lightness, Saturation) depending on \fBhls\fP.
+.PP
+On some color terminals, colors collide with highlights.
+You can register

+.PP
+For example, on many IBM PC consoles, the underline attribute collides with the

+These should have
+an \fBncv\fP capability of 2.
+.PP
+SVr4 curses does nothing with \fBncv\fP, ncurses recognizes it and optimizes
+the output in favor of colors.
+.PP
+.SS Miscellaneous
+If the terminal requires other than a null (zero) character as a pad, then this
+can be given as pad.
+Only the first character of the pad string is used.
+If the terminal does not have a pad character, specify npc.
+Note that ncurses implements the termcap-compatible \fBPC\fP variable;
+though the application may set this value to something other than
+a null, ncurses will test \fBnpc\fP first and use napms if the terminal
+has no pad character.
+.PP
+If the terminal can move up or down half a line,
+this can be indicated with
+.B hu
+(half-line up)
+and
+.B hd
+(half-line down).
+This is primarily useful for superscripts and subscripts on hard-copy terminals.
+If a hard-copy terminal can eject to the next page (form feed), give this as
+.B ff
+(usually control/L).
+.PP
+If there is a command to repeat a given character a given number of
+times (to save time transmitting a large number of identical characters)
+this can be indicated with the parameterized string
+.BR rep .
+The first parameter is the character to be repeated and the second
+is the number of times to repeat it.
+Thus, tparm(repeat_char, \(aqx\(aq, 10) is the same as \*(``xxxxxxxxxx\*(''.
+.PP
+If the terminal has a settable command character, such as the \s-1TEKTRONIX\s+1 4025,
+this can be indicated with
+.BR cmdch .
+A prototype command character is chosen which is used in all capabilities.
+This character is given in the
+.B cmdch
+capability to identify it.
+The following convention is supported on some UNIX systems:
+The environment is to be searched for a
+.B CC
+variable, and if found, all
+occurrences of the prototype character are replaced with the character
+in the environment variable.
+.PP
+Terminal descriptions that do not represent a specific kind of known
+terminal, such as
+.IR switch ,
+.IR dialup ,
+.IR patch ,
+and
+.IR network ,
+should include the
+.B gn
+(generic) capability so that programs can complain that they do not know
+how to talk to the terminal.
+(This capability does not apply to
+.I virtual
+terminal descriptions for which the escape sequences are known.)
+.PP
+If the terminal has a \*(``meta key\*('' which acts as a shift key,
+setting the 8th bit of any character transmitted, this fact can
+be indicated with
+.BR km .
+Otherwise, software will assume that the 8th bit is parity and it
+will usually be cleared.
+If strings exist to turn this \*(``meta mode\*('' on and off, they
+can be given as
+.B smm
+and
+.BR rmm .
+.PP
+If the terminal has more lines of memory than will fit on the screen
+at once, the number of lines of memory can be indicated with
+.BR lm .
+A value of
+.BR lm #0
+indicates that the number of lines is not fixed,
+but that there is still more memory than fits on the screen.
+.PP
+If the terminal is one of those supported by the \s-1UNIX\s+1 virtual
+terminal protocol, the terminal number can be given as
+.BR vt .
+.PP
+Media copy
+strings which control an auxiliary printer connected to the terminal
+can be given as
+.BR mc0 :
+print the contents of the screen,
+.BR mc4 :
+turn off the printer, and
+.BR mc5 :
+turn on the printer.
+When the printer is on, all text sent to the terminal will be sent
+to the printer.
+It is undefined whether the text is also displayed on the terminal screen
+when the printer is on.

+The parameter should not exceed 255.
+All text, including
+.BR mc4 ,
+is transparently passed to the printer while an
+.B mc5p

+.PP
+.SS Glitches and Braindamage
+.PP
+Hazeltine terminals, which do not allow \*(``~\*('' characters to be displayed should
+indicate \fBhz\fP.
+.PP
+Terminals which ignore a line-feed immediately after an \fBam\fP wrap,
+such as the Concept and vt100,
+should indicate \fBxenl\fP.
+.PP
+If
+.B el
+is required to get rid of standout
+(instead of merely writing normal text on top of it),
+\fBxhp\fP should be given.
+.PP
+Teleray terminals, where tabs turn all characters moved over to blanks,
+should indicate \fBxt\fP (destructive tabs).
+Note: the variable indicating this is now \*(``dest_tabs_magic_smso\*(''; in
+older versions, it was teleray_glitch.
+This glitch is also taken to mean that it is not possible to position
+the cursor on top of a \*(``magic cookie\*('',
+that to erase standout mode it is instead necessary to use
+delete and insert line.
+The ncurses implementation ignores this glitch.
+.PP
+The Beehive Superbee, which is unable to correctly transmit the escape
+or control/C characters, has
+.BR xsb ,
+indicating that the f1 key is used for escape and f2 for control/C.
+(Only certain Superbees have this problem, depending on the ROM.)
+Note that in older terminfo versions, this capability was called
+\*(``beehive_glitch\*(''; it is now \*(``no_esc_ctl_c\*(''.
+.PP
+Other specific terminal problems may be corrected by adding more
+capabilities of the form \fBx\fP\fIx\fP.
+.PP
+.SS Pitfalls of Long Entries
+.PP
+Long terminfo entries are unlikely to be a problem; to date, no entry has even
+approached terminfo's 4096-byte string-table maximum.
+Unfortunately, the termcap
+translations are much more strictly limited (to 1023 bytes), thus termcap translations
+of long terminfo entries can cause problems.
+.PP
+The man pages for 4.3BSD and older versions of \fBtgetent\fP instruct the user to
+allocate a 1024-byte buffer for the termcap entry.
+The entry gets null-terminated by
+the termcap library, so that makes the maximum safe length for a termcap entry
+1k\-1 (1023) bytes.
+Depending on what the application and the termcap library
+being used does, and where in the termcap file the terminal type that \fBtgetent\fP
+is searching for is, several bad things can happen.
+.PP
+Some termcap libraries print a warning message or exit if they find an
+entry that's longer than 1023 bytes; others do not; others truncate the
+entries to 1023 bytes.
+Some application programs allocate more than
+the recommended 1K for the termcap entry; others do not.
+.PP
+Each termcap entry has two important sizes associated with it: before
+\*(``tc\*('' expansion, and after \*(``tc\*('' expansion.
+\*(``tc\*('' is the capability that
+tacks on another termcap entry to the end of the current one, to add
+on its capabilities.
+If a termcap entry does not use the \*(``tc\*(''
+capability, then of course the two lengths are the same.
+.PP
+The \*(``before tc expansion\*('' length is the most important one, because it
+affects more than just users of that particular terminal.
+This is the
+length of the entry as it exists in /etc/termcap, minus the
+backslash-newline pairs, which \fBtgetent\fP strips out while reading it.
+Some termcap libraries strip off the final newline, too (GNU termcap does not).
+Now suppose:
+.bP
+a termcap entry before expansion is more than 1023 bytes long,
+.bP
+and the application has only allocated a 1k buffer,
+.bP
+and the termcap library (like the one in BSD/OS 1.1 and GNU) reads
+the whole entry into the buffer, no matter what its length, to see
+if it is the entry it wants,
+.bP
+and \fBtgetent\fP is searching for a terminal type that either is the
+long entry, appears in the termcap file after the long entry, or
+does not appear in the file at all (so that \fBtgetent\fP has to search
+the whole termcap file).
+.PP
+Then \fBtgetent\fP will overwrite memory, perhaps its stack, and probably core dump
+the program.
+Programs like telnet are particularly vulnerable; modern telnets
+pass along values like the terminal type automatically.
+The results are almost
+as undesirable with a termcap library, like SunOS 4.1.3 and Ultrix 4.4, that
+prints warning messages when it reads an overly long termcap entry.
+If a
+termcap library truncates long entries, like OSF/1 3.0, it is immune to dying
+here but will return incorrect data for the terminal.
+.PP
+The \*(``after tc expansion\*('' length will have a similar effect to the
+above, but only for people who actually set TERM to that terminal
+type, since \fBtgetent\fP only does \*(``tc\*('' expansion once it is found the
+terminal type it was looking for, not while searching.
+.PP
+In summary, a termcap entry that is longer than 1023 bytes can cause,
+on various combinations of termcap libraries and applications, a core
+dump, warnings, or incorrect operation.
+If it is too long even before
+\*(``tc\*('' expansion, it will have this effect even for users of some other
+terminal types and users whose TERM variable does not have a termcap
+entry.
+.PP
+When in \-C (translate to termcap) mode, the \fBncurses\fP implementation of
+\fB@TIC@\fP(1M) issues warning messages when the pre-tc length of a termcap
+translation is too long.
+The \-c (check) option also checks resolved (after tc
+expansion) lengths.
+.SS Binary Compatibility
+It is not wise to count on portability of binary terminfo entries between
+commercial UNIX versions.
+The problem is that there are at least two versions
+of terminfo (under HP\-UX and AIX) which diverged from System V terminfo after
+SVr1, and have added extension capabilities to the string table that (in the
+binary format) collide with System V and XSI Curses extensions.
+.SH EXTENSIONS
+.PP
+Searching for terminal descriptions in
+\fB$HOME/.terminfo\fP and TERMINFO_DIRS
+is not supported by older implementations.
+.PP
+Some SVr4 \fBcurses\fP implementations, and all previous to SVr4, do not
+interpret the %A and %O operators in parameter strings.
+.PP
+SVr4/XPG4 do not specify whether \fBmsgr\fP licenses movement while in
+an alternate-character-set mode (such modes may, among other things, map
+CR and NL to characters that do not trigger local motions).
+The \fBncurses\fP implementation ignores \fBmsgr\fP in \fBALTCHARSET\fP
+mode.
+This raises the possibility that an XPG4
+implementation making the opposite interpretation may need terminfo
+entries made for \fBncurses\fP to have \fBmsgr\fP turned off.
+.PP
+The \fBncurses\fP library handles insert-character and insert-character modes
+in a slightly non-standard way to get better update efficiency.
+See
+the \fBInsert/Delete Character\fP subsection above.
+.PP
+The parameter substitutions for \fBset_clock\fP and \fBdisplay_clock\fP are
+not documented in SVr4 or the XSI Curses standard.
+They are deduced from the
+documentation for the AT&T 505 terminal.
+.PP
+Be careful assigning the \fBkmous\fP capability.
+The \fBncurses\fP library wants to interpret it as \fBKEY_MOUSE\fP,
+for use by terminals and emulators like xterm
+that can return mouse-tracking information in the keyboard-input stream.
+.PP
+X/Open Curses does not mention italics.
+Portable applications must assume that numeric capabilities are
+signed 16-bit values.
+This includes the \fIno_color_video\fP (ncv) capability.
+The 32768 mask value used for italics with ncv can be confused with
+an absent or cancelled ncv.
+If italics should work with colors,
+then the ncv value must be specified, even if it is zero.
+.PP
+Different commercial ports of terminfo and curses support different subsets of
+the XSI Curses standard and (in some cases) different extension sets.
+Here
+is a summary, accurate as of October 1995:
+.bP
+\fBSVR4, Solaris, ncurses\fP \-\-
+These support all SVr4 capabilities.
+.bP
+\fBSGI\fP \-\-
+Supports the SVr4 set, adds one undocumented extended string
+capability (\fBset_pglen\fP).
+.bP
+\fBSVr1, Ultrix\fP \-\-
+These support a restricted subset of terminfo capabilities.
+The booleans end with \fBxon_xoff\fP;
+the numerics with \fBwidth_status_line\fP;
+and the strings with \fBprtr_non\fP.
+.bP
+\fBHP/UX\fP \-\-
+Supports the SVr1 subset, plus the SVr[234] numerics \fBnum_labels\fP,
+\fBlabel_height\fP, \fBlabel_width\fP, plus function keys 11 through 63, plus
+\fBplab_norm\fP, \fBlabel_on\fP, and \fBlabel_off\fP, plus some incompatible
+extensions in the string table.
+.bP
+\fBAIX\fP \-\-
+Supports the SVr1 subset, plus function keys 11 through 63, plus a number
+of incompatible string table extensions.
+.bP
+\fBOSF\fP \-\-
+Supports both the SVr4 set and the AIX extensions.

+.SH DESCRIPTION
+The \fB@TIC@\fP command translates a \fBterminfo\fP file from source
+format into compiled format.
+The compiled format is necessary for use with
+the library routines in \fBncurses\fP(3X).
+.PP
+As described in \fBterm\fP(\*n), the database may be either a directory
+tree (one file per terminal entry) or a hashed database (one record per entry).
+The \fB@TIC@\fP command writes only one type of entry,
+depending on how it was built:
+.bP
+For directory trees, the top-level directory, e.g., /usr/share/terminfo,
+specifies the location of the database.
+.bP
+For hashed databases, a filename is needed.
+If the given file is not found by that name,
+but can be found by adding the suffix ".db",
+then that is used.
+.IP
+The default name for the hashed database is the same as the
+default directory name (only adding a ".db" suffix).
+.PP
+In either case (directory or hashed database),
+\fB@TIC@\fP will create the container if it does not exist.
+For a directory, this would be the \*(``terminfo\*('' leaf,
+versus a "terminfo.db" file.
+.PP
+The results are normally placed in the system terminfo database \fB\*d\fP.
+The compiled terminal description can be placed
+in a different terminfo database.
+There are two ways to achieve this:
+.bP
+First, you may override the system default either by
+using the \fB\-o\fP option,
+or by setting the variable \fBTERMINFO\fP
+in your shell environment to a valid database location.
+.bP
+Secondly, if \fB@TIC@\fP cannot write in \fI\*d\fP
+or the location specified using your TERMINFO variable,
+it looks for the directory \fI$HOME/.terminfo\fP
+(or hashed database \fI$HOME/.terminfo.db)\fP;
+if that location exists, the entry is placed there.
+.PP
+Libraries that read terminfo entries are expected to check in succession
+.bP
+a location specified with the TERMINFO environment variable,
+.bP
+\fI$HOME/.terminfo\fP,
+.bP
+directories listed in the TERMINFO_DIRS environment variable,
+.bP
+a compiled-in list of directories (@TERMINFO_DIRS@), and
+.bP
+the system terminfo database (\fI\*d\fP).
+.SS ALIASES
+.PP
+This is the same program as @INFOTOCAP@ and @CAPTOINFO@;
+usually those are linked to, or copied from this program:
+.bP
+When invoked as @INFOTOCAP@, @TIC@ sets the \fB\-I\fP option.
+.bP
+When invoked as @CAPTOINFO@, @TIC@ sets the \fB\-C\fP option.
+.SS OPTIONS
+.TP
+\fB\-0\fP
+restricts the output to a single line
+.TP
+\fB\-1\fP
+restricts the output to a single column
+.TP
+\fB\-a\fP
+tells \fB@TIC@\fP to retain commented-out capabilities rather than discarding
+them.
+Capabilities are commented by prefixing them with a period.
+This sets the \fB\-x\fP option, because it treats the commented-out
+entries as user-defined names.
+If the source is termcap, accept the 2-character names required by version 6.
+Otherwise these are ignored.
+.TP
+\fB\-C\fP
+Force source translation to termcap format.
+Note: this differs from the \fB\-C\fP
+option of \fB@INFOCMP@\fP(1M) in that it does not merely translate capability
+names, but also translates terminfo strings to termcap format.
+Capabilities
+that are not translatable are left in the entry under their terminfo names
+but commented out with two preceding dots.
+The actual format used incorporates some improvements for escaped characters
+from terminfo format.
+For a stricter BSD-compatible translation, add the \fB\-K\fP option.
+.IP
+If this is combined with \fB\-c\fP, \fB@TIC@\fP makes additional checks
+to report cases where the terminfo values do not have an exact equivalent
+in termcap form.
+For example:
+.RS
+.bP
+\fBsgr\fP usually will not convert, because termcap lacks the ability to
+work with more than two parameters, and because termcap lacks many of
+the arithmetic/logical operators used in terminfo.
+.bP
+capabilities with more than one delay or with delays before the end of
+the string will not convert completely.
+.RE
+.TP
+\fB\-c\fP
+tells \fB@TIC@\fP to only check \fIfile\fP for errors,
+including syntax problems and bad use-links.
+If you specify \fB\-C\fP (\fB\-I\fP) with this option, the code
+will print warnings about entries which, after use resolution, are more than
+1023 (4096) bytes long.
+Due to a fixed buffer length in older termcap libraries,
+as well as buggy checking for the buffer length
+(and a documented limit in terminfo),
+these entries may cause core
+dumps with other implementations.
+.IP
+\fB@TIC@\fP checks string capabilities to ensure that those with parameters
+will be valid expressions.
+It does this check only for the predefined string capabilities;
+those which are defined with the \fB\-x\fP option are ignored.
+.TP
+\fB\-D\fP
+tells \fB@TIC@\fP to print the database locations that it knows about, and exit.
+The first location shown is the one to which it would write compiled
+terminal descriptions.
+If \fB@TIC@\fP is not able to find a writable database location
+according to the rules summarized above,
+it will print a diagnostic and exit with an error rather than
+printing a list of database locations.
+.TP
+\fB\-e \fInames\fR
+Limit writes and translations to the following comma-separated list of
+terminals.
+If any name or alias of a terminal matches one of the names in
+the list, the entry will be written or translated as normal.
+Otherwise no output will be generated for it.
+The option value is interpreted as a file containing the list if it
+contains a '/'.
+(Note: depending on how @TIC@ was compiled,
+this option may require \fB\-I\fP or \fB\-C\fP.)
+.TP
+\fB\-f\fP
+Display complex terminfo strings which contain if/then/else/endif expressions
+indented for readability.
+.TP
+\fB\-G\fP
+Display constant literals in decimal form
+rather than their character equivalents.
+.TP
+\fB\-g\fP
+Display constant character literals in quoted form
+rather than their decimal equivalents.
+.TP
+\fB\-I\fP
+Force source translation to terminfo format.
+.TP
+\fB\-K\fP
+Suppress some longstanding ncurses extensions to termcap format,
+e.g., "\\s" for space.
+.TP
+\fB\-L\fP
+Force source translation to terminfo format
+using the long C variable names listed in <\fBterm.h\fP>
+.TP
+\fB\-N\fP
+Disable smart defaults.
+Normally, when translating from termcap to terminfo, the compiler makes
+a number of assumptions about the defaults of string capabilities
+\fBreset1_string\fP, \fBcarriage_return\fP, \fBcursor_left\fP,
+\fBcursor_down\fP, \fBscroll_forward\fP, \fBtab\fP, \fBnewline\fP,
+\fBkey_backspace\fP, \fBkey_left\fP, and \fBkey_down\fP, then attempts
+to use obsolete termcap capabilities to deduce correct values.
+It also
+normally suppresses output of obsolete termcap capabilities such as \fBbs\fP.
+This option forces a more literal translation that also preserves the
+obsolete capabilities.
+.TP
+\fB\-o\fIdir\fR
+Write compiled entries to given database location.
+Overrides the TERMINFO environment variable.
+.TP
+\fB\-Q\fIn\fR
+Rather than show source in terminfo (text) format,
+print the compiled (binary) format in hexadecimal or base64 form,
+depending on the option's value:
+.RS 8
+.TP 3
+1
+hexadecimal
+.TP 3
+2
+base64
+.TP 3
+3
+hexadecimal and base64
+.RE
+.TP
+\fB\-q\fP
+Suppress comments and blank lines when showing translated source.
+.TP
+\fB\-R\fIsubset\fR
+Restrict output to a given subset.
+This option is for use with archaic
+versions of terminfo like those on SVr1, Ultrix, or HP-UX that do not support
+the full set of SVR4/XSI Curses terminfo; and outright broken ports like AIX 3.x
+that have their own extensions incompatible with SVr4/XSI.
+Available subsets
+are \*(``SVr1\*('', \*(``Ultrix\*('', \*(``HP\*('', \*(``BSD\*('' and \*(``AIX\*('';
+see \fBterminfo\fP(\*n) for details.
+.TP
+\fB\-r\fP
+Force entry resolution (so there are no remaining tc capabilities) even
+when doing translation to termcap format.
+This may be needed if you are
+preparing a termcap file for a termcap library (such as GNU termcap through
+version 1.3 or BSD termcap through 4.3BSD) that does not handle multiple
+tc capabilities per entry.
+.TP
+\fB\-s\fP
+Summarize the compile by showing the database location into which entries
+are written, and the number of entries which are compiled.
+.TP
+\fB\-T\fP
+eliminates size-restrictions on the generated text.
+This is mainly useful for testing and analysis, since the compiled
+descriptions are limited (e.g., 1023 for termcap, 4096 for terminfo).
+.TP
+\fB\-t\fP
+tells \fB@TIC@\fP to discard commented-out capabilities.
+Normally when translating from terminfo to termcap,
+untranslatable capabilities are commented-out.
+.TP 5
+\fB\-U\fP
+tells \fB@TIC@\fP to not post-process the data after parsing the source file.
+Normally, it infers data which is commonly missing in older terminfo data,
+or in termcaps.
+.TP
+\fB\-V\fP
+reports the version of ncurses which was used in this program, and exits.
+.TP
+\fB\-v\fIn\fR
+specifies that (verbose) output be written to standard error trace
+information showing \fB@TIC@\fP's progress.
+.IP
+The optional parameter \fIn\fP is a number from 1 to 9, inclusive,
+indicating the desired level of detail of information.
+.RS
+.bP
+If ncurses is built without tracing support, the optional parameter is ignored.
+.bP
+If \fIn\fP is omitted, the default level is 1.
+.bP
+If \fIn\fP is specified and greater than 1, the level of
+detail is increased, and the output is written (with tracing information)
+to the \*(``trace\*('' file.

+\fB\-W\fP
+By itself, the \fB\-w\fP option will not force long strings to be wrapped.
+Use the \fB\-W\fP option to do this.
+.IP
+If you specify both \fB\-f\fP and \fB\-W\fP options,
+the latter is ignored when \fB\-f\fP has already split the line.
+.TP
+\fB\-w\fIn\fR
+specifies the width of the output.
+The parameter is optional.
+If it is omitted, it defaults to 60.
+.TP
+\fB\-x\fP
+Treat unknown capabilities as user-defined (see \fBuser_caps(\*n)\fP).
+That is, if you supply a capability name which \fB@TIC@\fP does not recognize,
+it will infer its type (boolean, number or string) from the syntax and
+make an extended table entry for that.
+User-defined capability strings
+whose name begins with \*(``k\*('' are treated as function keys.
+.SS PARAMETERS
+.TP
+\fIfile\fP
+contains one or more \fBterminfo\fP terminal descriptions in source
+format [see \fBterminfo\fP(\*n)].
+Each description in the file
+describes the capabilities of a particular terminal.
+.IP
+If \fIfile\fP is \*(``-\*('', then the data is read from the standard input.
+The \fIfile\fP parameter may also be the path of a character-device.
+.SS PROCESSING
+.PP
+All but one of the capabilities recognized by \fB@TIC@\fP are documented
+in \fBterminfo\fP(\*n).
+The exception is the \fBuse\fP capability.
+.PP
+When a \fBuse\fP=\fIentry\fP\-\fIname\fP field is discovered in a
+terminal entry currently being compiled, \fB@TIC@\fP reads in the binary
+from \fB\*d\fP to complete the entry.
+(Entries created from
+\fIfile\fP will be used first.
+\fB@TIC@\fP duplicates the capabilities in
+\fIentry\fP\-\fIname\fP for the current entry, with the exception of
+those capabilities that explicitly are defined in the current entry.
+.PP
+When an entry, e.g., \fBentry_name_1\fP, contains a
+\fBuse=\fIentry\fR_\fIname\fR_\fI2\fR field, any canceled
+capabilities in \fIentry\fR_\fIname\fR_\fI2\fP must also appear in
+\fBentry_name_1\fP before \fBuse=\fP for these capabilities to be
+canceled in \fBentry_name_1\fP.
+.PP
+Total compiled entries cannot exceed 4096 bytes.
+The name field cannot
+exceed 512 bytes.
+Terminal names exceeding the maximum alias length
+(32 characters on systems with long filenames, 14 characters otherwise)
+will be truncated to the maximum alias length
+and a warning message will be printed.
+.SH HISTORY
+.PP
+System V Release 2 provided a \fBtic\fP utility.
+It accepted a single option: \fB\-v\fP (optionally followed by a number).
+According to Ross Ridge's comment in \fImytinfo\fP,
+this version of \fBtic\fP was
+unable to represent cancelled capabilities.
+.PP
+System V Release 3 provided a different \fBtic\fP utility,
+written by Pavel Curtis,
+(originally named \*(``compile\*('' in \fIpcurses\fP).
+This added an option \fB\-c\fP to check the file for
+errors, with the caveat that errors in \*(``use=\*('' links
+would not be reported.
+System V Release 3 documented a few warning messages which
+did not appear in \fIpcurses\fP.
+While the program itself was changed little as development
+continued with System V Release 4,
+the table of capabilities grew from 180 (\fIpcurses\fP) to 464 (Solaris).
+.PP
+In early development of ncurses (1993),
+Zeyd Ben-Halim used the table from \fImytinfo\fP to
+extend the \fIpcurses\fP table to 469 capabilities
+(456 matched SVr4, 8 were only in SVr4, 13 were not in SVr4).
+Of those 13, 11 were ultimately discarded
+(perhaps to match the draft of X/Open Curses).
+The exceptions were
+\fBmemory_lock_above\fP and
+\fBmemory_unlock\fP (see \fBuser_caps\fP(5)).
+.PP
+Eric Raymond incorporated parts of \fImytinfo\fP into ncurses
+to implement the termcap-to-terminfo source conversion,
+and extended that to begin development of
+the corresponding terminfo-to-termcap source conversion,
+Thomas Dickey completed that development over the course of several years.
+.PP
+In 1999, Thomas Dickey added the \fB\-x\fP option
+to support user-defined capabilities.
+.PP
+In 2010, Roy Marples provided a \fBtic\fP program
+and terminfo library for NetBSD.
+That implementation adapts several features from ncurses,
+including \fB@TIC@\fP's \fB\-x\fP option.
+.PP
+The \fB\-c\fP option tells \fB@TIC@\fP to check for problems in the
+terminfo source file.
+Continued development provides additional checks:
+.bP
+\fIpcurses\fP had 8 warnings
+.bP
+ncurses in 1996 had 16 warnings
+.bP
+Solaris (SVr4) curses has 28 warnings
+.bP
+NetBSD tic in 2019 has 19 warnings.
+.bP
+ncurses in 2019 has 96 warnings
+.PP
+The checking done in ncurses' \fB@TIC@\fP helps with the conversion to
+termcap, as well as pointing out errors and inconsistencies.
+It is also used to ensure consistency with the user-defined capabilities.
+There are 527 distinct capabilities in ncurses' terminal database;
+128 of those are user-defined.
+.SH PORTABILITY
+.PP
+X/Open Curses, Issue 7 (2009) provides a brief description of \fBtic\fP.
+It lists one option: \fB\-c\fP.
+The omission of \fB\-v\fP is unexpected.
+The change history states that the description is derived from True64 UNIX.
+According to its manual pages, that system also supported the \fB\-v\fP option.
+.PP
+Shortly after Issue 7 was released, Tru64 was discontinued.
+As of 2019, the surviving implementations of \fBtic\fP
+are SVr4 (AIX, HP-UX and Solaris),
+ncurses
+and NetBSD curses.
+The SVr4 \fBtic\fP programs all support the \fB\-v\fP option.
+The NetBSD \fBtic\fP program follows X/Open's documentation,
+omitting the \fB\-v\fP option.
+.PP
+The X/Open rationale states that some implementations of \fBtic\fP
+read terminal descriptions from the standard input if the \fIfile\fP
+parameter is omitted.
+None of these implementations do that.
+Further, it comments that some may choose to read from \*(''./terminfo.src\*(''
+but that is obsolescent behavior from SVr2,
+and is not (for example) a documented feature of SVr3.
+.SS COMPATIBILITY
+There is some evidence that historic \fB@TIC@\fP implementations treated
+description fields with no whitespace in them as additional aliases or
+short names.
+This \fB@TIC@\fP does not do that, but it does warn when
+description fields may be treated that way and check them for dangerous
+characters.
+.SS EXTENSIONS
+Unlike the SVr4 \fB@TIC@\fP command, this implementation can actually
+compile termcap sources.
+In fact, entries in terminfo and termcap syntax can
+be mixed in a single source file.
+See \fBterminfo\fP(\*n) for the list of
+termcap names taken to be equivalent to terminfo names.
+.PP
+The SVr4 manual pages are not clear on the resolution rules for \fBuse\fP
+capabilities.
+This implementation of \fB@TIC@\fP will find \fBuse\fP targets anywhere
+in the source file, or anywhere in the file tree rooted at \fBTERMINFO\fP (if
+\fBTERMINFO\fP is defined),
+or in the user's \fI$HOME/.terminfo\fP database
+(if it exists),
+or (finally) anywhere in the system's file tree of
+compiled entries.
+.PP
+The error messages from this \fB@TIC@\fP have the same format as GNU C
+error messages, and can be parsed by GNU Emacs's compile facility.
+.PP
+Aside from \fB\-c\fP and \fB\-v\fP, options are not portable:
+.bP
+Most of @TIC@'s options
+are not supported by SVr4 \fBtic\fP:

+\fB@TOE@\fP [\fB\-v\fP[\fIn\fP]] [\fB\-ahsuUV\fP] \fIfile...\fP
+.br
+.SH DESCRIPTION
+.PP
+With no options,
+\fB@TOE@\fP lists all available terminal types by primary name
+with descriptions.
+File arguments specify the directories to be scanned; if no
+such arguments are given,
+your default terminfo directory is scanned.
+If you also specify the \fB\-h\fP option,
+a directory header will be issued as each
+directory is entered.
+.PP
+There are other options intended for use by terminfo file maintainers:
+.TP
+\fB\-a\fP
+report on all of the terminal databases which ncurses would search,
+rather than only the first one that it finds.
+.IP
+If the \fB\-s\fP is also given, \fB@TOE@\fP
+adds a column to the report,
+showing (like \fBconflict\fP(1)) which entries which
+belong to a given terminal database.
+An "*" marks entries which differ, and "+" marks equivalent entries.
+.IP
+Without the \fB\-s\fP option, \fB@TOE@\fP does not attempt to merge
+duplicates in its report
+.TP
+\fB\-s\fP
+sort the output by the entry names.
+.TP
+\fB\-u\fP \fIfile\fP
+says to write a report to the standard output,
+listing dependencies in the given terminfo/termcap source file.
+The report condenses the \*(``use\*('' relation:
+each line consists of the primary name of a terminal that
+has use capabilities,
+followed by a colon,
+followed by the
+whitespace-separated primary names of all terminals which occur in those use
+capabilities,
+followed by a newline
+.TP
+\fB\-U\fP \fIfile\fP
+says to write a report to the standard output,
+listing reverse dependencies in the given terminfo/termcap source file.
+The report reverses the \*(``use\*('' relation:
+each line consists of the primary name of a
+terminal that occurs in use capabilities,
+followed by a colon,
+followed by the
+whitespace-separated primary names of all terminals which depend on it,
+followed by a newline.
+.TP
+\fB\-v\fIn\fR
+specifies that (verbose) output be written to standard error,
+showing \fB@TOE@\fP's progress.
+.IP
+The optional parameter \fIn\fP is a number from 1 to 10,
+interpreted as for \fB@TIC@\fP(1M).
+If ncurses is built without tracing support, the optional parameter is ignored.
+.TP
+\fB\-V\fP
+reports the version of ncurses which was used in this program,
+and exits.
+.SH EXAMPLES
+.PP
+Without sorting, the \fB\-a\fP option reports all of the names found
+in all of the terminal databases found by the \fBTERMINFO\fP and
+\fBTERMINFO_DIRS\fP environment variables:

+.SH DESCRIPTION
+The \fB@TPUT@\fP utility uses the \fBterminfo\fP database to make the
+values of terminal-dependent capabilities and information available to
+the shell (see \fBsh\fP(1)), to initialize or reset the terminal, or
+return the long name of the requested terminal type.
+The result depends upon the capability's type:
+.RS 3
+.TP 5
+string
+\fB@TPUT@\fP writes the string to the standard output.
+No trailing newline is supplied.
+.TP
+integer
+\fB@TPUT@\fP writes the decimal value to the standard output,
+with a trailing newline.
+.TP
+boolean
+\fB@TPUT@\fP simply sets the exit code
+(\fB0\fP for TRUE if the terminal has the capability,
+\fB1\fP for FALSE if it does not),
+and writes nothing to the standard output.
+.RE
+.PP
+Before using a value returned on the standard output,
+the application should test the exit code
+(e.g., \fB$?\fP, see \fBsh\fP(1)) to be sure it is \fB0\fP.
+(See the \fBEXIT CODES\fP and \fBDIAGNOSTICS\fP sections.)
+For a complete list of capabilities
+and the \fIcapname\fP associated with each, see \fBterminfo\fP(5).
+.SS Options
+.TP
+\fB\-S\fP
+allows more than one capability per invocation of \fB@TPUT@\fP.  The
+capabilities must be passed to \fB@TPUT@\fP from the standard input
+instead of from the command line (see example).
+Only one \fIcapname\fP is allowed per line.
+The \fB\-S\fP option changes the
+meaning of the \fB0\fP and \fB1\fP boolean and string exit codes (see the
+EXIT CODES section).
+.IP
+Because some capabilities may use
+\fIstring\fP parameters rather than \fInumbers\fP,
+\fB@TPUT@\fP uses a table and the presence of parameters in its input
+to decide whether to use \fBtparm\fP(3X),
+and how to interpret the parameters.
+.TP
+\fB\-T\fItype\fR
+indicates the \fItype\fP of terminal.
+Normally this option is
+unnecessary, because the default is taken from the environment
+variable \fBTERM\fP.
+If \fB\-T\fP is specified, then the shell
+variables \fBLINES\fP and \fBCOLUMNS\fP will also be ignored.
+.TP
+\fB\-V\fP
+reports the version of ncurses which was used in this program, and exits.
+.TP
+.B \-x
+do not attempt to clear the terminal's scrollback buffer
+using the extended \*(``E3\*('' capability.
+.SS Commands
+A few commands (\fBinit\fP, \fBreset\fP and \fBlongname\fP) are
+special; they are defined by the \fB@TPUT@\fP program.
+The others are the names of \fIcapabilities\fP from the terminal database
+(see \fBterminfo\fP(5) for a list).
+Although \fBinit\fP and \fBreset\fP resemble capability names,
+\fB@TPUT@\fP uses several capabilities to perform these special functions.
+.TP
+\fIcapname\fP
+indicates the capability from the terminal database.
+.IP
+If the capability is a string that takes parameters, the arguments
+following the capability will be used as parameters for the string.
+.IP
+Most parameters are numbers.
+Only a few terminal capabilities require string parameters;
+\fB@TPUT@\fP uses a table to decide which to pass as strings.
+Normally \fB@TPUT@\fP uses \fBtparm\fP(3X) to perform the substitution.
+If no parameters are given for the capability,
+\fB@TPUT@\fP writes the string without performing the substitution.
+.TP
+\fBinit\fP
+If the terminal database is present and an entry for the user's
+terminal exists (see \fB\-T\fItype\fR, above), the following will
+occur:
+.RS
+.TP 5
+(1)
+first, \fB@TPUT@\fP retrieves the current terminal mode settings
+for your terminal.
+It does this by successively testing
+.RS
+.bP
+the standard error,
+.bP
+standard output,
+.bP
+standard input and
+.bP
+ultimately \*(``/dev/tty\*(''
+.RE
+.IP
+to obtain terminal settings.
+Having retrieved these settings, \fB@TPUT@\fP remembers which
+file descriptor to use when updating settings.
+.TP

+.bP

+.bP
+reset any unset special characters to their default values
+.RE
+.TP 5
+(2)
+Instead of putting out \fIinitialization\fP strings, the terminal's
+\fIreset\fP strings will be output if present
+(\fBrs1\fP, \fBrs2\fP, \fBrs3\fP, \fBrf\fP).
+If the \fIreset\fP strings are not present, but \fIinitialization\fP
+strings are, the \fIinitialization\fP strings will be output.
+.RE
+.IP
+Otherwise, \fBreset\fP acts identically to \fBinit\fP.
+.TP
+\fBlongname\fP
+If the terminal database is present and an entry for the
+user's terminal exists (see \fB\-T\fItype\fR above), then the long name
+of the terminal will be put out.
+The long name is the last
+name in the first line of the terminal's description in the
+\fBterminfo\fP database [see \fBterm\fP(5)].
+.SS Aliases
+\fB@TPUT@\fP handles the \fBclear\fP, \fBinit\fP and \fBreset\fP
+commands specially:
+it allows for the possibility that it is invoked by a link with those names.
+.PP
+If \fB@TPUT@\fP is invoked by a link named \fBreset\fP, this has the
+same effect as \fB@TPUT@ reset\fP.
+The \fB@TSET@\fP(\*n) utility also treats a link named \fBreset\fP specially.
+.PP
+Before ncurses 6.1, the two utilities were different from each other:
+.bP
+\fB@TSET@\fP utility reset the terminal modes and special characters
+(not done with \fB@TPUT@\fP).
+.bP
+On the other hand, \fB@TSET@\fP's repertoire of terminal capabilities for
+resetting the terminal was more limited,
+i.e., only \fBreset_1string\fP, \fBreset_2string\fP and \fBreset_file\fP
+in contrast to the tab-stops and margins which are set by this utility.
+.bP
+The \fBreset\fP program is usually an alias for \fB@TSET@\fP,
+because of this difference with resetting terminal modes and special characters.
+.PP
+With the changes made for ncurses 6.1, the \fIreset\fP feature of the
+two programs is (mostly) the same.
+A few differences remain:
+.bP
+The \fB@TSET@\fP program waits one second when resetting,
+in case it happens to be a hardware terminal.
+.bP
+The two programs write the terminal initialization strings
+to different streams (i.e., the standard error for \fB@TSET@\fP and the
+standard output for \fB@TPUT@\fP).
+.IP
+\fBNote:\fP although these programs write to different streams,
+redirecting their output to a file will capture only part of their actions.
+The changes to the terminal modes are not affected by redirecting the output.
+.PP
+If \fB@TPUT@\fP is invoked by a link named \fBinit\fP, this has the
+same effect as \fB@TPUT@ init\fP.
+Again, you are less likely to use that link because another program
+named \fBinit\fP has a more well-established use.
+.SS Terminal Size
+.PP
+Besides the special commands (e.g., \fBclear\fP),
+@TPUT@ treats certain terminfo capabilities specially:
+\fBlines\fP and \fBcols\fP.
+@TPUT@ calls \fBsetupterm\fP(3X) to obtain the terminal size:
+.bP
+first, it gets the size from the terminal database
+(which generally is not provided for terminal emulators
+which do not have a fixed window size)
+.bP
+then it asks the operating system for the terminal's size
+(which generally works, unless connecting via a serial line which
+does not support \fINAWS\fP: negotiations about window size).
+.bP
+finally, it inspects the environment variables \fBLINES\fP and \fBCOLUMNS\fP
+which may override the terminal size.
+.PP
+If the \fB\-T\fP option is given
+@TPUT@ ignores the environment variables by calling \fBuse_tioctl(TRUE)\fP,
+relying upon the operating system (or finally, the terminal database).
+.SH EXAMPLES

+.SH HISTORY
+The \fBtput\fP command was begun by Bill Joy in 1980.
+The initial version only cleared the screen.
+.PP
+AT&T System V provided a different \fBtput\fP command:
+.bP
+SVr2 provided a rudimentary \fBtput\fP
+which checked the parameter against each
+predefined capability and returned the corresponding value.
+This version of \fBtput\fP did not use \fBtparm\fP(3X) for
+the capabilities which are parameterized.
+.bP
+SVr3 replaced that, a year later, by a more extensive program
+whose \fBinit\fP and \fBreset\fP subcommands
+(more than half the program) were incorporated from
+the \fBreset\fP feature of BSD \fBtset\fP written by Eric Allman.
+.bP
+SVr4 added color initialization using the \fBorig_colors\fP and
+\fBorig_pair\fP capabilities in the \fBinit\fP subcommand.
+.PP
+Keith Bostic replaced the BSD \fBtput\fP command in 1989
+with a new implementation
+based on the AT&T System V program \fBtput\fP.
+Like the AT&T program, Bostic's version
+accepted some parameters named for \fIterminfo\fP capabilities
+(\fBclear\fP, \fBinit\fP, \fBlongname\fP and \fBreset\fP).
+However (because he had only \fItermcap\fP available),
+it accepted \fItermcap\fP names for other capabilities.
+Also, Bostic's BSD \fBtput\fP did not modify the terminal I/O modes
+as the earlier BSD \fBtset\fP had done.
+.PP
+At the same time, Bostic added a shell script named \*(``clear\*('',
+which used \fBtput\fP to clear the screen.
+.PP
+Both of these appeared in 4.4BSD,
+becoming the \*(``modern\*('' BSD implementation of \fBtput\fP.
+.PP
+This implementation of \fBtput\fP began from a different source than
+AT&T or BSD: Ross Ridge's \fImytinfo\fP package, published on
+\fIcomp.sources.unix\fP in December 1992.
+Ridge's program made more sophisticated use of the terminal capabilities
+than the BSD program.
+Eric Raymond used that \fBtput\fP program
+(and other parts of \fImytinfo\fP) in ncurses in June 1995.
+Using the portions dealing with terminal capabilities
+almost without change,
+Raymond made improvements to the way the command-line parameters
+were handled.
+.SH PORTABILITY
+.PP
+This implementation of \fBtput\fP differs from AT&T \fBtput\fP in
+two important areas:
+.bP
+\fB@TPUT@\fP \fIcapname\fP writes to the standard output.
+That need not be a regular terminal.
+However, the subcommands which manipulate terminal modes
+may not use the standard output.
+.IP
+The AT&T implementation's \fBinit\fP and \fBreset\fP commands
+use the BSD (4.1c) \fBtset\fP source, which manipulates terminal modes.
+It successively tries standard output, standard error, standard input
+before falling back to \*(``/dev/tty\*('' and finally just assumes
+a 1200Bd terminal.
+When updating terminal modes, it ignores errors.
+.IP
+Until changes made after ncurses 6.0,
+\fB@TPUT@\fP did not modify terminal modes.
+\fB@TPUT@\fP now uses a similar scheme,
+using functions shared with \fB@TSET@\fP
+(and ultimately based on the 4.4BSD \fBtset\fP).
+If it is not able to open a terminal, e.g., when running in \fBcron\fP(1),
+\fB@TPUT@\fP will return an error.
+.bP
+AT&T \fBtput\fP guesses the type of its \fIcapname\fP operands by seeing if
+all of the characters are numeric, or not.
+.IP
+Most implementations which provide support for \fIcapname\fP operands
+use the \fBtparm\fP function to expand parameters in it.
+That function expects a mixture of numeric and string parameters,
+requiring \fB@TPUT@\fP to know which type to use.
+.IP
+This implementation uses a table to determine the parameter types for
+the standard \fIcapname\fP operands, and an internal library
+function to analyze nonstandard \fIcapname\fP operands.
+.IP
+Besides providing more reliable operation than AT&T's utility,
+a portability problem is introduced by this analysis:
+An OpenBSD developer adapted the internal library function from ncurses
+to port NetBSD's termcap-based \fBtput\fP to terminfo.
+That had been modified to interpret multiple commands on a line.
+Portable applications should not rely upon this feature;
+ncurses provides it to support applications written
+specifically for OpenBSD.
+.PP
+This implementation (unlike others) can accept both \fItermcap\fP
+and \fIterminfo\fP names for the \fIcapname\fP feature,
+if
+\fItermcap\fP support is compiled in.
+However, the predefined \fItermcap\fP and \fIterminfo\fP names have two
+ambiguities in this case (and the \fIterminfo\fP name is assumed):
+.bP
+The \fItermcap\fP name \fBdl\fP corresponds to
+the \fIterminfo\fP name \fBdl1\fP (delete one line).
+.br
+The \fIterminfo\fP name \fBdl\fP corresponds to
+the \fItermcap\fP name \fBDL\fP (delete a given number of lines).
+.bP
+The \fItermcap\fP name \fBed\fP corresponds to
+the \fIterminfo\fP name \fBrmdc\fP (end delete mode).
+.br
+The \fIterminfo\fP name \fBed\fP corresponds to
+the \fItermcap\fP name \fBcd\fP (clear to end of screen).
+.PP
+The \fBlongname\fP and \fB\-S\fP options, and the parameter-substitution
+features used in the \fBcup\fP example,
+were not supported in BSD curses before 4.3reno (1989) or in
+AT&T/USL curses before SVr4 (1988).
+.PP
+IEEE Std 1003.1/The Open Group  Base Specifications Issue 7 (POSIX.1-2008)
+documents only the operands for \fBclear\fP, \fBinit\fP and \fBreset\fP.
+There are a few interesting observations to make regarding that:
+.bP
+In this implementation, \fBclear\fP is part of the \fIcapname\fP support.
+The others (\fBinit\fP and \fBlongname\fP) do not correspond to terminal
+capabilities.
+.bP
+Other implementations of \fBtput\fP on
+SVr4-based systems such as Solaris, IRIX64 and HPUX
+as well as others such as AIX and Tru64
+provide support for \fIcapname\fP operands.
+.bP
+A few platforms such as FreeBSD recognize termcap names rather
+than terminfo capability names in their respective \fBtput\fP commands.
+Since 2010, NetBSD's \fBtput\fP uses terminfo names.
+Before that, it (like FreeBSD) recognized termcap names.
+.IP
+Beginning in 2021, FreeBSD uses the ncurses \fBtput\fP,
+configured for both terminfo (tested first) and termcap (as a fallback).
+.PP
+Because (apparently) \fIall\fP of the certified Unix systems
+support the full set of capability names, the reasoning for documenting
+only a few may not be apparent.
+.bP
+X/Open Curses Issue 7 documents \fBtput\fP differently, with \fIcapname\fP
+and the other features used in this implementation.
+.bP
+That is, there are two standards for \fBtput\fP:
+POSIX (a subset) and X/Open Curses (the full implementation).
+POSIX documents a subset to avoid the complication of including X/Open Curses
+and the terminal capabilities database.
+.bP
+While it is certainly possible to write a \fBtput\fP program
+without using curses,
+none of the systems which have a curses implementation provide
+a \fBtput\fP utility which does not provide the \fIcapname\fP feature.
+.PP
+X/Open Curses Issue 7 (2009) is the first version to document utilities.
+However that part of X/Open Curses does not follow existing practice
+(i.e., Unix features documented in SVID 3):
+.bP
+It assigns exit code 4 to \*(``invalid operand\*('',
+which may be the same as \fIunknown capability\fP.
+For instance, the source code for Solaris' xcurses uses the term
+\*(``invalid\*('' in this case.
+.bP
+It assigns exit code 255 to a numeric variable that is not specified in
+the terminfo database.
+That likely is a documentation error,
+confusing the \fB\-1\fP written to the standard output for an absent
+or cancelled numeric value versus an (unsigned) exit code.
+.PP
+The various Unix systems (AIX, HPUX, Solaris) use the same exit-codes
+as ncurses.
+.PP
+NetBSD curses documents different exit codes which do not correspond
+to either ncurses or X/Open.

+.SH DESCRIPTION
+.SS tset - initialization
+This program initializes terminals.
+.PP
+First, \fB@TSET@\fP retrieves the current terminal mode settings
+for your terminal.
+It does this by successively testing
+.bP
+the standard error,
+.bP
+standard output,
+.bP
+standard input and
+.bP
+ultimately \*(``/dev/tty\*(''
+.PP
+to obtain terminal settings.
+Having retrieved these settings, \fB@TSET@\fP remembers which
+file descriptor to use when updating settings.
+.PP
+Next, \fB@TSET@\fP determines the type of terminal that you are using.
+This determination is done as follows, using the first terminal type found.
+.PP
+1. The \fBterminal\fP argument specified on the command line.
+.PP
+2. The value of the \fBTERM\fP environmental variable.
+.PP
+3. (BSD systems only.) The terminal type associated with the standard
+error output device in the \fI/etc/ttys\fP file.
+(On System\-V-like UNIXes and systems using that convention,
+\fBgetty\fP(1) does this job by setting
+\fBTERM\fP according to the type passed to it by \fI/etc/inittab\fP.)
+.PP
+4. The default terminal type, \*(``unknown\*(''.
+.PP
+If the terminal type was not specified on the command-line, the \fB\-m\fP
+option mappings are then applied (see the section
+.B TERMINAL TYPE MAPPING
+for more information).
+Then, if the terminal type begins with a question mark (\*(``?\*(''), the
+user is prompted for confirmation of the terminal type.
+An empty
+response confirms the type, or, another type can be entered to specify
+a new type.
+Once the terminal type has been determined,
+the terminal description for the terminal is retrieved.
+If no terminal description is found
+for the type, the user is prompted for another terminal type.
+.PP
+Once the terminal description is retrieved,
+.bP
+if the \*(``\fB\-w\fP\*('' option is enabled, \fB@TSET@\fP may update
+the terminal's window size.
+.IP
+If the window size cannot be obtained from the operating system,
+but the terminal description (or environment, e.g., \fBLINES\fP
+and \fBCOLUMNS\fP variables specify this),
+use this to set the operating system's notion of the window size.
+.bP
+if the \*(``\fB\-c\fP\*('' option is enabled,
+the backspace, interrupt and line kill characters
+(among many other things) are set
+.bP
+unless the \*(``\fB\-I\fP\*('' option is enabled,
+the terminal
+and tab \fIinitialization\fP strings are sent to the standard error output,
+and \fB@TSET@\fP waits one second (in case a hardware reset was issued).
+.bP
+Finally, if the erase, interrupt and line kill characters have changed,
+or are not set to their default values, their values are displayed to the
+standard error output.
+.SS reset - reinitialization
+.PP
+When invoked as \fB@RESET@\fP, \fB@TSET@\fP sets the terminal
+modes to \*(``sane\*('' values:
+.bP
+sets cooked and echo modes,
+.bP
+turns off cbreak and raw modes,
+.bP
+turns on newline translation and
+.bP
+resets any unset special characters to their default values
+.PP
+before
+doing the terminal initialization described above.
+Also, rather than using the terminal \fIinitialization\fP strings,
+it uses the terminal \fIreset\fP strings.
+.PP
+The \fB@RESET@\fP command is useful
+after a program dies leaving a terminal in an abnormal state:
+.bP
+you may have to type
+.sp
+    \fI<LF>\fB@RESET@\fI<LF>\fR
+.sp
+(the line-feed character is normally control-J) to get the terminal
+to work, as carriage-return may no longer work in the abnormal state.
+.bP
+Also, the terminal will often not echo the command.
+.SH OPTIONS
+.PP
+The options are as follows:
+.TP 5
+.B \-c
+Set control characters and modes.
+.TP 5
+.BI \-e\  ch
+Set the erase character to \fIch\fP.
+.TP
+.B \-I
+Do not send the terminal or tab initialization strings to the terminal.
+.TP
+.BI \-i\  ch
+Set the interrupt character to \fIch\fP.
+.TP
+.BI \-k\  ch
+Set the line kill character to \fIch\fP.
+.TP
+.BI \-m\  mapping
+Specify a mapping from a port type to a terminal.
+See the section
+.B TERMINAL TYPE MAPPING
+for more information.
+.TP
+.B \-Q
+Do not display any values for the erase, interrupt and line kill characters.
+Normally \fB@TSET@\fP displays the values for control characters which
+differ from the system's default values.
+.TP
+.B \-q
+The terminal type is displayed to the standard output, and the terminal is
+not initialized in any way.
+The option \*(``\-\*('' by itself is equivalent but archaic.
+.TP
+.B \-r
+Print the terminal type to the standard error output.
+.TP
+.B \-s
+Print the sequence of shell commands to initialize the environment variable
+\fBTERM\fP to the standard output.
+See the section
+.B SETTING THE ENVIRONMENT
+for details.
+.TP
+.B \-V
+reports the version of ncurses which was used in this program, and exits.
+.TP
+.B \-w
+Resize the window to match the size deduced via \fBsetupterm\fP(3X).
+Normally this has no effect,
+unless \fBsetupterm\fP is not able to detect the window size.
+.PP
+The arguments for the \fB\-e\fP, \fB\-i\fP, and \fB\-k\fP
+options may either be entered as actual characters
+or by using the \*(``hat\*(''
+notation, i.e., control-h may be specified as \*(``^H\*('' or \*(``^h\*(''.
+.PP
+If neither \fB\-c\fP or \fB\-w\fP is given, both options are assumed.
+.
+.SH SETTING THE ENVIRONMENT
+It is often desirable to enter the terminal type and information about
+the terminal's capabilities into the shell's environment.
+This is done using the \fB\-s\fP option.
+.PP
+When the \fB\-s\fP option is specified, the commands to enter the information
+into the shell's environment are written to the standard output.
+If
+the \fBSHELL\fP environmental variable ends in \*(``csh\*('', the commands
+are for \fBcsh\fP, otherwise, they are for \fBsh\fP(1).
+Note, the \fBcsh\fP commands set and unset the shell variable
+\fBnoglob\fP, leaving it unset.
+The following line in the \fB.login\fP
+or \fB.profile\fP files will initialize the environment correctly:
+.sp
+    eval \`@TSET@ \-s options ... \`
+.
+.SH TERMINAL TYPE MAPPING
+When the terminal is not hardwired into the system (or the current
+system information is incorrect) the terminal type derived from the
+\fI/etc/ttys\fP file or the \fBTERM\fP environmental variable is often
+something generic like \fBnetwork\fP, \fBdialup\fP, or \fBunknown\fP.
+When \fB@TSET@\fP is used in a startup script it is often desirable to
+provide information about the type of terminal used on such ports.
+.PP
+The \fB\-m\fP options maps
+from some set of conditions to a terminal type, that is, to
+tell \fB@TSET@\fP
+\*(``If I'm on this port at a particular speed,
+guess that I'm on that kind of terminal\*(''.
+.PP
+The argument to the \fB\-m\fP option consists of an optional port type, an
+optional operator, an optional baud rate specification, an optional
+colon (\*(``:\*('') character and a terminal type.
+The port type is a
+string (delimited by either the operator or the colon character).
+The operator may be any combination of
+\*(``>\*('',
+\*(``<\*('',
+\*(``@\*('',
+and \*(``!\*('';
+\*(``>\*('' means greater than,
+\*(``<\*('' means less than,
+\*(``@\*('' means equal to and
+\*(``!\*('' inverts the sense of the test.
+The baud rate is specified as a number and is compared with the speed
+of the standard error output (which should be the control terminal).
+The terminal type is a string.
+.PP
+If the terminal type is not specified on the command line, the \fB\-m\fP
+mappings are applied to the terminal type.
+If the port type and baud
+rate match the mapping, the terminal type specified in the mapping
+replaces the current type.
+If more than one mapping is specified, the
+first applicable mapping is used.
+.PP
+For example, consider the following mapping: \fBdialup>9600:vt100\fP.
+The port type is dialup , the operator is >, the baud rate
+specification is 9600, and the terminal type is vt100.
+The result of
+this mapping is to specify that if the terminal type is \fBdialup\fP,
+and the baud rate is greater than 9600 baud, a terminal type of
+\fBvt100\fP will be used.
+.PP
+If no baud rate is specified, the terminal type will match any baud rate.
+If no port type is specified, the terminal type will match any port type.
+For example, \fB\-m dialup:vt100 \-m :?xterm\fP
+will cause any dialup port, regardless of baud rate, to match the terminal
+type vt100, and any non-dialup port type to match the terminal type ?xterm.
+Note, because of the leading question mark, the user will be
+queried on a default port as to whether they are actually using an xterm
+terminal.
+.PP
+No whitespace characters are permitted in the \fB\-m\fP option argument.
+Also, to avoid problems with meta-characters, it is suggested that the
+entire \fB\-m\fP option argument be placed within single quote characters,
+and that \fBcsh\fP users insert a backslash character (\*(``\e\*('') before
+any exclamation marks (\*(``!\*('').
+.SH HISTORY
+.PP
+A \fBreset\fP command appeared in 1BSD (March 1978), written by Kurt Shoens.
+This program set the \fIerase\fP and \fIkill\fP characters
+to \fB^H\fP (backspace) and \fB@\fP respectively.
+Mark Horton improved that in 3BSD (October 1979), adding
+\fIintr\fP, \fIquit\fP, \fIstart\fP/\fIstop\fP and \fIeof\fP characters
+as well as changing the program to avoid modifying any user settings.
+That version of \fBreset\fP did not use the termcap database.
+.PP
+A separate \fBtset\fP command was provided in 1BSD by Eric Allman,
+using the termcap database.
+Allman's comments in the source code indicate
+that he began work in October 1977,
+continuing development over the next few years.
+.PP
+According to comments in the source code,
+the \fBtset\fP program was modified in September 1980,
+to use logic copied from the 3BSD \*(``reset\*(''
+when it was invoked as \fBreset\fP.
+This version appeared in 4.1cBSD, late in 1982.
+.PP
+Other developers (e.g., Keith Bostic and Jim Bloom)
+continued to modify \fBtset\fP until 4.4BSD was released in 1993.
+.PP
+The \fBncurses\fP implementation
+was lightly adapted from the 4.4BSD sources for a terminfo environment by Eric
+S. Raymond <esr@snark.thyrsus.com>.
+.SH COMPATIBILITY
+.PP
+Neither IEEE Std 1003.1/The Open Group Base Specifications Issue 7
+(POSIX.1-2008) nor
+X/Open Curses Issue 7 documents \fB@TSET@\fP or \fB@RESET@\fP.
+.PP
+The AT&T \fBtput\fP utility (AIX, HPUX, Solaris)
+incorporated the terminal-mode manipulation as well as termcap-based features
+such as resetting tabstops from \fBtset\fP in BSD (4.1c),
+presumably with the intention of making \fBtset\fP obsolete.
+However, each of those systems still provides \fBtset\fP.
+In fact, the commonly-used \fBreset\fP utility
+is always an alias for \fBtset\fP.
+.PP
+The \fB@TSET@\fP utility provides for backward-compatibility with BSD
+environments (under most modern UNIXes, \fB/etc/inittab\fP and \fBgetty\fP(1)
+can set \fBTERM\fP appropriately for each dial-up line; this obviates what was
+\fB@TSET@\fP's most important use).
+This implementation behaves like 4.4BSD
+\fBtset\fP, with a few exceptions specified here.
+.PP
+A few options are different
+because the \fBTERMCAP\fP variable
+is no longer supported under terminfo-based \fBncurses\fP:
+.bP
+The \fB\-S\fP option of BSD \fBtset\fP no longer works;
+it prints an error message to the standard error and dies.
+.bP
+The \fB\-s\fP option only sets \fBTERM\fP, not \fBTERMCAP\fP.
+.PP
+There was an undocumented 4.4BSD feature
+that invoking \fBtset\fP via a link named
+\*(``TSET\*('' (or via any other name beginning with an upper-case letter)
+set the terminal to use upper-case only.
+This feature has been omitted.
+.PP
+The \fB\-A\fP, \fB\-E\fP, \fB\-h\fP, \fB\-u\fP and \fB\-v\fP
+options were deleted from the \fB@TSET@\fP
+utility in 4.4BSD.
+None of them were documented in 4.3BSD and all are
+of limited utility at best.
+The \fB\-a\fP, \fB\-d\fP, and \fB\-p\fP options are similarly
+not documented or useful, but were retained as they appear to be in
+widespread use.
+It is strongly recommended that any usage of these
+three options be changed to use the \fB\-m\fP option instead.
+The \fB\-a\fP, \fB\-d\fP, and \fB\-p\fP options
+are therefore omitted from the usage summary above.
+.PP
+Very old systems, e.g., 3BSD, used a different terminal driver which
+was replaced in 4BSD in the early 1980s.
+To accommodate these older systems, the 4BSD \fB@TSET@\fP provided a
+\fB\-n\fP option to specify that the new terminal driver should be used.
+This implementation does not provide that choice.
+.PP
+It is still permissible to specify the \fB\-e\fP, \fB\-i\fP,
+and \fB\-k\fP options without arguments,
+although it is strongly recommended that such usage be fixed to
+explicitly specify the character.
+.PP
+As of 4.4BSD,
+executing \fB@TSET@\fP as \fB@RESET@\fP no longer implies the \fB\-Q\fP option.
+Also, the interaction between the \- option and the \fIterminal\fP
+argument in some historic implementations of \fB@TSET@\fP has been removed.
+.PP
+The \fB\-c\fP and \fB\-w\fP options are not found in earlier implementations.
+However, a different window size-change feature was provided in 4.4BSD.
+.bP
+In 4.4BSD, \fBtset\fP uses the window size from the termcap description
+to set the window size if \fBtset\fP is not able to obtain the window
+size from the operating system.
+.bP
+In ncurses, \fB@TSET@\fP obtains the window size using
+\fBsetupterm\fP, which may be from
+the operating system,
+the \fBLINES\fP and \fBCOLUMNS\fP environment variables or
+the terminal description.
+.PP
+Obtaining the window size from the terminal description is common to
+both implementations, but considered obsolescent.
+Its only practical use is for hardware terminals.
+Generally speaking, a window size would be unset only if there were
+some problem obtaining the value from the operating system
+(and \fBsetupterm\fP would still fail).
+For that reason, the \fBLINES\fP and \fBCOLUMNS\fP environment variables
+may be useful for working around window-size problems.
+Those have the drawback that if the window is resized,
+those variables must be recomputed and reassigned.
+To do this more easily, use the \fBresize\fP(1) program.
+.SH ENVIRONMENT
+The \fB@TSET@\fP command uses these environment variables:
+.TP 5
+SHELL
+tells \fB@TSET@\fP whether to initialize \fBTERM\fP using \fBsh\fP(1) or
+\fBcsh\fP(1) syntax.
+.TP 5
+TERM
+Denotes your terminal type.
+Each terminal type is distinct, though many are similar.
+.TP 5
+TERMCAP
+may denote the location of a termcap database.
+If it is not an absolute pathname, e.g., begins with a \*(``/\*('',
+\fB@TSET@\fP removes the variable from the environment before looking
+for the terminal description.

+.SH NAME
+user_caps \- user-defined terminfo capabilities
+.SH SYNOPSIS
+.B @TIC@ -x, @INFOCMP@ -x
+.SH DESCRIPTION
+.SS Background
+.PP
+Before ncurses 5.0,
+terminfo databases used a \fIfixed repertoire\fP of terminal
+capabilities designed for the SVr2 terminal database in 1984,
+and extended in stages through SVr4 (1989),
+and standardized in the Single Unix Specification beginning in 1995.
+.PP
+Most of the \fIextensions\fP in this fixed repertoire were additions
+to the tables of boolean, numeric and string capabilities.
+Rather than change the meaning of an existing capability, a new name was added.
+The terminfo database uses a binary format; binary compatibility was
+ensured by using a header which gave the number of items in the
+tables for each type of capability.
+The standardization was incomplete:
+.bP
+The \fIbinary format\fP itself is not described
+in the X/Open Curses documentation.
+Only the \fIsource format\fP is described.
+.IP
+Library developers rely upon the SVr4 documentation,
+and reverse-engineering the compiled terminfo files to match the binary format.
+.bP
+Lacking a standard for the binary format, most implementations
+copy the SVr2 binary format, which uses 16-bit signed integers,
+and is limited to 4096-byte entries.
+.IP
+The format cannot represent very large numeric capabilities,
+nor can it represent large numbers of special keyboard definitions.
+.bP
+The tables of capability names differ between implementations.
+.IP
+Although they \fImay\fP provide all of the standard capability names,
+the position in the tables differs because some features were added as needed,
+while others were added (out of order) to comply with X/Open Curses.
+.IP
+While ncurses' repertoire of predefined capabilities is closest to Solaris,
+Solaris's terminfo database has a few differences from
+the list published by X/Open Curses.
+For example, ncurses can be configured with tables which match the
+terminal databases for AIX, HP-UX or OSF/1,
+rather than the default Solaris-like configuration.
+.bP
+In SVr4 curses and ncurses,
+the terminal database is defined at compile-time using a text file
+which lists the different terminal capabilities.
+.IP
+In principle, the text-file can be extended,
+but doing this requires recompiling and reinstalling the library.
+The text-file used in ncurses for terminal capabilities includes
+details for various systems past the documented X/Open Curses features.
+For example, ncurses supports these capabilities in each configuration:
+.RS 8
+.TP 5
+memory_lock
+(meml)
+lock memory above cursor
+.TP 5
+memory_unlock
+(memu)
+unlock memory
+.TP 5
+box_chars_1
+(box1)
+box characters primary set
+.RE
+.IP
+The memory lock/unlock capabilities were included because they were used
+in the X11R6 terminal description for \fBxterm\fP(1).
+The \fIbox1\fP capability is used in @TIC@ to help with terminal descriptions
+written for AIX.
+.PP
+During the 1990s, some users were reluctant to use terminfo
+in spite of its performance advantages over termcap:
+.bP
+The fixed repertoire prevented users from adding features
+for unanticipated terminal improvements
+(or required them to reuse existing capabilities as a workaround).
+.bP
+The limitation to 16-bit signed integers was also mentioned.
+Because termcap stores everything as a string,
+it could represent larger numbers.
+.PP
+Although termcap's extensibility was rarely used
+(it was never the \fIspeaker\fP who had actually used the feature),
+the criticism had a point.
+ncurses 5.0 provided a way to detect nonstandard capabilities,
+determine their
+type and optionally store and retrieve them in a way which did not interfere
+with other applications.
+These are referred to as \fIuser-defined capabilities\fP because no
+modifications to the toolset's predefined capability names are needed.
+.PP
+The ncurses utilities \fB@TIC@\fP and \fB@INFOCMP@\fP have a command-line
+option \*(``\-x\*('' to control whether the nonstandard capabilities
+are stored or retrieved.
+A library function \fBuse_extended_names\fP
+is provided for the same purpose.
+.PP
+When compiling a terminal database, if \*(``\-x\*('' is set,
+\fB@TIC@\fP will store a user-defined capability if the capability name is not
+one of the predefined names.
+.PP
+Because ncurses provides a termcap library interface,
+these user-defined capabilities may be visible to termcap applications:
+.bP
+The termcap interface (like all implementations of termcap)
+requires that the capability names are 2-characters.
+.IP
+When the capability is simple enough for use in a termcap application,
+it is provided as a 2-character name.
+.bP
+There are other
+user-defined capabilities which refer to features not usable in termcap,
+e.g., parameterized strings that use more than two parameters
+or use more than the trivial expression support provided by termcap.
+For these, the terminfo database should have only capability names with
+3 or more characters.
+.bP
+Some terminals can send distinct strings for special keys (cursor-,
+keypad- or function-keys) depending on modifier keys (shift, control, etc.).
+While terminfo and termcap have a set of 60 predefined function-key names,
+to which a series of keys can be assigned,
+that is insufficient for more than a dozen keys multiplied by more than
+a couple of modifier combinations.
+The ncurses database uses a convention based on \fBxterm\fP(1) to
+provide extended special-key names.
+.IP
+Fitting that into termcap's limitation of 2-character names
+would be pointless.
+These extended keys are available only with terminfo.
+.SS Recognized capabilities
+.PP
+The ncurses library uses the user-definable capabilities.
+While the terminfo database may have other extensions,
+ncurses makes explicit checks for these:
+.RS 3
+.TP 3
+AX
+\fIboolean\fP, asserts that the terminal interprets SGR 39 and SGR 49
+by resetting the foreground and background color, respectively, to the default.
+.IP
+This is a feature recognized by the \fBscreen\fP program as well.
+.TP 3
+E3
+\fIstring\fP, tells how to clear the terminal's scrollback buffer.
+When present, the \fBclear\fP(1) program sends this before clearing
+the terminal.
+.IP
+The command \*(``\fBtput clear\fP\*('' does the same thing.
+.TP 3
+NQ
+used to suppress a consistency check in @TIC@ for the ncurses capabilities
+in user6 through user9 (u6, u7, u8 and u9)
+which tell how to query the terminal's cursor position
+and its device attributes.
+.TP 3
+RGB
+\fIboolean\fP, \fInumber\fP \fBor\fP \fIstring\fP,
+used to assert that the
+\fBset_a_foreground\fP and
+\fBset_a_background\fP capabilities correspond to \fIdirect colors\fP,
+using an RGB (red/green/blue) convention.
+This capability allows the \fBcolor_content\fP function to
+return appropriate values without requiring the application
+to initialize colors using \fBinit_color\fP.
+.IP
+The capability type determines the values which ncurses sees:
+.RS 3
+.TP 3
+\fIboolean\fP
+implies that the number of bits for red, green and blue are the same.
+Using the maximum number of colors,
+ncurses adds two, divides that sum by three, and assigns the result
+to red, green and blue in that order.
+.IP
+If the number of bits needed for the number of colors is not a multiple
+of three, the blue (and green) components lose in comparison to red.
+.TP 3
+\fInumber\fP
+tells ncurses what result to add to red, green and blue.
+If ncurses runs out of bits,
+blue (and green) lose just as in the \fIboolean\fP case.
+.TP 3
+\fIstring\fP
+explicitly list the number of bits used for red, green and blue components
+as a slash-separated list of decimal integers.
+.RE
+.IP
+Because there are several RGB encodings in use,
+applications which make assumptions about the number of bits per color
+are unlikely to work reliably.
+As a trivial case, for example, one could define \fBRGB#1\fP
+to represent the standard eight ANSI colors, i.e., one bit per color.
+.TP 3
+U8
+\fInumber\fP,
+asserts that ncurses must use Unicode values for line-drawing characters,
+and that it should ignore the alternate character set capabilities
+when the locale uses UTF-8 encoding.
+For more information, see the discussion of
+\fBNCURSES_NO_UTF8_ACS\fP in \fBncurses\fP(3X).
+.IP
+Set this capability to a nonzero value to enable it.
+.TP 3
+XM
+\fIstring\fP,
+override ncurses's built-in string which
+enables/disables \fBxterm\fP(1) mouse mode.
+.IP
+ncurses sends a character sequence to the terminal to initialize mouse mode,
+and when the user clicks the mouse buttons or (in certain modes) moves the
+mouse, handles the characters sent back by the terminal to tell it what
+was done with the mouse.
+.IP
+The mouse protocol is enabled when
+the \fImask\fP passed in the \fBmousemask\fP function is nonzero.
+By default, ncurses handles the responses for the X11 xterm mouse protocol.
+It also knows about the \fISGR 1006\fP xterm mouse protocol,
+but must to be told to look for this specifically.
+It will not be able to guess which mode is used,
+because the responses are enough alike that only confusion would result.
+.IP

+.SS Extended key-definitions
+.PP
+Several terminals provide the ability to send distinct strings for
+combinations of modified special keys.
+There is no standard for what those keys can send.
+.PP
+Since 1999, \fBxterm\fP(1) has supported
+\fIshift\fP, \fIcontrol\fP, \fIalt\fP, and \fImeta\fP modifiers which produce
+distinct special-key strings.
+In a terminal description, ncurses has no special knowledge of the
+modifiers used.
+Applications can use the \fInaming convention\fP established for \fBxterm\fP
+to find these special keys in the terminal description.
+.PP
+Starting with the curses convention that \fIkey names\fP begin with \*(``k\*(''
+and that shifted special keys are an uppercase name,
+ncurses' terminal database defines these names to which a suffix is added:
+.RS 5
+.TS
+tab(/) ;
+l l .
+\fBName\fP/\fBDescription\fP
+_
+kDC/special form of kdch1 (delete character)
+kDN/special form of kcud1 (cursor down)
+kEND/special form of kend (End)
+kHOM/special form of khome (Home)
+kLFT/special form of kcub1 (cursor-left or cursor-back)
+kNXT/special form of knext (Next, or Page-Down)
+kPRV/special form of kprev (Prev, or Page-Up)
+kRIT/special form of kcuf1 (cursor-right, or cursor-forward)
+kUP/special form of kcuu1 (cursor-up)
+.TE
+.RE
+.PP
+These are the suffixes used to denote the modifiers:
+.RS 5
+.TS
+tab(/) ;
+l l .
+\fBValue\fP/\fBDescription\fP
+_
+2/Shift
+3/Alt
+4/Shift + Alt
+5/Control
+6/Shift + Control
+7/Alt + Control
+8/Shift + Alt + Control
+9/Meta
+10/Meta + Shift
+11/Meta + Alt
+12/Meta + Alt + Shift
+13/Meta + Ctrl
+14/Meta + Ctrl + Shift
+15/Meta + Ctrl + Alt
+16/Meta + Ctrl + Alt + Shift
+.TE
+.RE
+.PP
+None of these are predefined; terminal descriptions can refer to \fInames\fP
+which ncurses will allocate at runtime to \fIkey-codes\fP.
+To use these keys in an ncurses program, an application could do this:
+.bP
+using a list of extended key \fInames\fP,
+ask \fBtigetstr\fP(3X) for their values, and
+.bP
+given the list of values,
+ask \fBkey_defined\fP(3X) for the \fIkey-code\fP which
+would be returned for those keys by \fBwgetch\fP(3X).
+.PP
+.\"
+.SH PORTABILITY
+.PP
+The \*(``\-x\*('' extension feature of \fB@TIC@\fP and \fB@INFOCMP@\fP
+has been adopted in NetBSD curses.
+That implementation stores user-defined capabilities,
+but makes no use of these capabilities itself.

+.SH NAME
+\fBwresize\fP \- resize a curses window
+.SH SYNOPSIS
+\fB#include <curses.h>\fP
+.sp
+\fBint wresize(WINDOW *\fIwin\fB, int \fIlines\fB, int \fIcolumns\fB);\fR
+.SH DESCRIPTION
+This is an extension to the curses library.
+It reallocates storage for an \fBncurses\fP
+window to adjust its dimensions to the specified values.
+If either dimension is larger than the current values, the
+window's data is filled with blanks that have the current background rendition
+(as set by \fBwbkgdset\fP) merged into them.
+.SH RETURN VALUE
+The function returns the integer \fBERR\fP upon failure and \fBOK\fP on success.
+It will fail if either of the dimensions less than or equal to zero,
+or if an error occurs while (re)allocating memory for the window.
+.SH NOTES
+The only restriction placed on the dimensions is that they be greater than zero.
+The dimensions are not compared to \fBcurses\fP screen dimensions to
+simplify the logic of \fBresizeterm\fP.
+The caller must ensure that the window's dimensions fit within the
+actual screen dimensions.
+.SH PORTABILITY
+.PP
+It is not possible to resize windows with SVr4 curses.
+.PP
+This extension of ncurses was introduced in mid-1995.
+It was adopted in NetBSD curses (2001) and PDCurses (2003).
+.SH SEE ALSO
+\fBresizeterm\fP(3X).
+.SH AUTHOR
+Thomas Dickey (from an equivalent function written in 1988 for BSD curses).

+# System-dependent wrapper for 'lint' that creates a lint-library via the
+# following method (XXX is the name of the library):
+#	a.  If the file llib-lXXX doesn't exist, create it using the make-rule
+#	b.  Process llib-lXXX with the system's lint utility, making
+#	    llib-lXXX.ln
+#	c.  Install llib-lXXX.ln in the lib directory.
+#
+# Using the intermediate file llib-lXXX bypasses a weakness of lint (passing
+# through warning messages from the original source-files).
+#
+# There are two drawbacks to this approach:
+#	a.  On a few systems, you'll have to manually-edit the llib-lXXX file
+#	    to get a usable lint-library (not all C-preprocessors work well).
+#	b.  The system's lint utility won't recognize -lXXX as a lint-library
+#	    (Use tdlint as a wrapper; it is designed for this).

+# Use this script as a wrapper when running executables linked to shared
+# libraries on systems that use the $LD_LIBRARY_PATH variable and don't embed
+# the soname's path within the linked executable (such as IRIX), e.g,
+#
+#	shlib knight
+#
+# Setting LD_LIBRARY_PATH, overrides/supplements the loader's normal search
+# path, and works on most systems.  The drawback is that then the environment
+# variable has to be set to run the programs within this directory tree.
+#
+# For Linux (and other systems using the GNU loader), we can use the rpath
+# directive, which embeds the pathname of the library within the executable.
+# Using the Linux loader's rpath directive introduces a constraint, since
+# it's embedded into the binary, and means that the binary cannot be moved
+# around (though it'll work if the $exec_prefix convention that puts the bin
+# and lib directories under the same parent is followed).
+#
+# Using the actual soname (e.g., ../lib/libncurses.so) alone, is a more
+# flexible solution; you can link without having to set the environment
+# variable, and on some systems (IRIX) you can even run the resulting binaries
+# without setting LD_LIBRARY_PATH.
+#
+# Using a conventional link, with -L and -l options on Linux results in a
+# statically linked executable, which we don't want at all.

+######## TERMINAL TYPE DESCRIPTIONS SOURCE FILE
+#
+# This version of terminfo.src is distributed with ncurses and is maintained
+# by Thomas E. Dickey (TD).
+#
+# Report bugs and new terminal descriptions to
+#	bug-ncurses@gnu.org
+#

+#
+# The original header is preserved below for reference.  It is noted that there
+# is a "newer" version which differs in some cosmetic details (but actually
+# stopped updates several years ago); we have decided to not change the header
+# unless there is also a change in content.
+#
+# To further muddy the waters, it is noted that changes to this file as part of
+# maintenance of ncurses (since 1996) are generally conceded to be copyright
+# under the ncurses MIT-style license.  That was the effect of the agreement
+# which the principal authors of ncurses made in 1998.  However, since much of
+# the file itself is of unknown authorship (and the disclaimer below makes it
+# obvious that Raymond cannot or will not convey rights over those parts),
+# there is no explicit copyright notice on the file itself.
+#
+# It would also be a nuisance to split the file into unknown/known authorship
+# and move pieces as they are maintained, since many of the maintenance changes
+# have been small corrections to Raymond's translations to/from termcap format,
+# correcting the data but not the accompanying annotations.
+#
+# In any case, note that almost half of this file is not data but annotations
+# which reflect creative effort.  Furthermore, the structure of entries to
+# reuse common chunks also is creative (and subject to copyright).  Finally,
+# some portions of the data are derivative work under a compatible MIT-style
+# license from xterm.

+#
+# PURPOSE OF THIS FILE:
+#
+# This file describes the capabilities of various character-cell terminals,
+# as needed by software such as screen-oriented editors.
+#
+# Other terminfo and termcap files exist, supported by various OS vendors
+# or as relics of various older versions of UNIX.  This one is the longest
+# and most comprehensive one in existence.  It subsumes not only the entirety
+# of the historical 4.4BSD, GNU, System V and SCO termcap files and the BRL
+# termcap file, but also large numbers of vendor-maintained termcap and
+# terminfo entries more complete and carefully tested than those in historical
+# termcap/terminfo versions.
+#
+# Pointers to related resources (including the ncurses distribution) may
+# be found at <http://www.tuxedo.org/terminfo>.
+#
+# INTERNATIONALIZATION:
+#
+# This file uses only the US-ASCII character set (no ISO8859 characters).
+#
+# This file assumes a US-ASCII character set. If you need to fix this, start
+# by global-replacing \E(B and \E)B with the appropriate ISO 6429 enablers
+# for your character set.  \E(A and \E)A enables the British character set
+# with the pound sign at position 2/3.
+#
+# In a Japanese-processing environment using EUC/Japanese or Shift-JIS,
+# C1 characters are considered the first-byte set of the Japanese encodings,
+# so \E)0 should be avoided in <enacs> and initialization strings.
+#
+# FILE FORMAT:
+#
+# The version you are looking at may be in any of three formats: master
+# (terminfo with OT capabilities), stock terminfo, or termcap.  You can tell
+# which by the format given in the header above.
+#
+# The master format is accepted and generated by the terminfo tools in the
+# ncurses suite; it differs from stock (System V-compatible) terminfo only
+# in that it admits a group of capabilities (prefixed `OT') equivalent to
+# various obsolete termcap capabilities.  You can, thus, convert from master
+# to stock terminfo simply by filtering with `sed "/OT[^,]*,/s///"'; but if
+# you have ncurses `tic -I' is nicer (among other things, it automatically
+# outputs entries in a canonical form).
+#
+# The termcap version is generated automatically from the master version
+# using tic -C.  This filtering leaves in the OT capabilities under their
+# original termcap names.  All translated entries fit within the 1023-byte
+# string-table limit of archaic termcap libraries except where explicitly
+# noted below.  Note that the termcap translation assumes that your termcap
+# library can handle multiple tc capabilities in an entry. 4.4BSD has this
+# capability.  Older versions of GNU termcap, through 1.3, do not.
+#
+# For details on these formats, see terminfo(5) in the ncurses distribution,
+# and termcap(5) in the 4.4BSD Unix Programmer's Manual.  Be aware that 4.4BSD
+# curses has been declared obsolete by the caretakers of the 4.4BSD sources
+# as of June 1995; they are encouraging everyone to migrate to ncurses.
+#
+# Note: unlike some other distributed terminfo files (Novell Unix & SCO's),
+# no entry in this file has embedded comments.  This is so source translation
+# to termcap only has to carry over leading comments.  Also, no name field
+# contains embedded whitespace (such whitespace confuses rdist).
+#
+# Further note: older versions of this file were often installed with an editor
+# script (reorder) that moved the most common terminal types to the front of
+# the file.  This should no longer be necessary, as the file is now ordered
+# roughly by type frequency with ANSI/VT100 and other common types up front.
+#
+# Some information has been merged in from terminfo files distributed by
+# USL and SCO (see COPYRIGHTS AND OTHER DELUSIONS below).  Much information
+# comes from vendors who maintain official terminfos for their hardware
+# (notably DEC and Wyse).
+#
+# A detailed change history is included at the end of this file.
+#
+# FILE ORGANIZATION:
+#
+# Comments in this file begin with # - they cannot appear in the middle
+# of a terminfo/termcap entry (this feature had to be sacrificed in order
+# to allow standard terminfo and termcap syntax to be generated cleanly from
+# the master format).  Individual capabilities are commented out by
+# placing a period between the colon and the capability name.
+#
+# The file is divided up into major sections (headed by lines beginning with
+# the string "########") and minor sections (beginning with "####"); do
+#
+#	grep "^####" <file> | more
+#
+# to see a listing of section headings.  The intent of the divisions is
+# (a) to make it easier to find things, and (b) to order the database so
+# that important and frequently-encountered terminal types are near the
+# front (so that you'll get reasonable search efficiency from a linear
+# search of the termcap form even if you don't use reorder).  Minor sections
+# usually correspond to manufacturers or standard terminal classes.
+# Parenthesized words following manufacturer names are type prefixes or
+# product line names used by that manufacturers.
+#
+# HOW TO READ THE ENTRIES:
+#
+# The first name in an entry is the canonical name for the model or
+# type, last entry is a verbose description.  Others are mnemonic synonyms for
+# the terminal.
+#
+# Terminal names look like <manufacturer> <model> - <modes/options>
+# The part to the left of the dash, if a dash is present, describes the
+# particular hardware of the terminal.  The part to the right may be used
+# for flags indicating special ROMs, extra memory, particular terminal modes,
+# or user preferences.
+#
+# All names should be in lower case, for consistency in typing.
+#
+# The following are conventionally used suffixes:
+#	-2p	Has two pages of memory.  Likewise 4p, 8p, etc.
+#	-am	Enable auto-margin.
+#	-m	Monochrome.  Suppress color support
+#	-mc	Magic-cookie.  Some terminals (notably older Wyses) can

+# Entries with embedded plus signs are designed to be included through use/tc

+#
+# To avoid search clashes, some older all-numeric names for terminals have
+# been removed (i.e., "33" for the Model 33 Teletype, "2621" for the HP2621).
+# All primary names of terminals now have alphanumeric prefixes.
+#
+# Comments marked "esr" are mostly results of applying the termcap-compiler
+# code packaged with ncurses and contemplating the resulting error messages.
+# In many cases, these indicated obvious fixes to syntax garbled by the
+# composers.  In a few cases, I was able to deduce corrected forms for garbled
+# capabilities by looking at context.  All the information in the original
+# entries is preserved in the comments.
+#
+# In the comments, terminfo capability names are bracketed with <> (angle
+# brackets).  Termcap capability names are bracketed with :: (colons).
+#
+# INTERPRETATION OF USER CAPABILITIES
+#
+# The System V Release 4 and XPG4 terminfo format defines ten string
+# capabilities for use by applications, <u0>...<u9>.   In this file, we use
+# certain of these capabilities to describe functions which are not covered
+# by terminfo.  The mapping is as follows:
+#
+#	u9	terminal enquire string (equiv. to ANSI/ECMA-48 DA)
+#	u8	terminal answerback description
+#	u7	cursor position request (equiv. to VT100/ANSI/ECMA-48 DSR 6)
+#	u6	cursor position report (equiv. to ANSI/ECMA-48 CPR)
+#
+# The terminal enquire string <u9> should elicit an answerback response
+# from the terminal.  Common values for <u9> will be ^E (on older ASCII
+# terminals) or \E[c (on newer VT100/ANSI/ECMA-48-compatible terminals).
+#
+# The cursor position request (<u7>) string should elicit a cursor position
+# report.  A typical value (for VT100 terminals) is \E[6n.
+#
+# The terminal answerback description (u8) must consist of an expected
+# answerback string.  The string may contain the following scanf(3)-like
+# escapes:
+#
+#	%c	Accept any character
+#	%[...]	Accept any number of characters in the given set
+#
+# The cursor position report (<u6>) string must contain two scanf(3)-style
+# %d format elements.  The first of these must correspond to the Y coordinate
+# and the second to the %d.  If the string contains the sequence %i, it is
+# taken as an instruction to decrement each value after reading it (this is
+# the inverse sense from the cup string).  The typical CPR value is
+# \E[%i%d;%dR (on VT100/ANSI/ECMA-48-compatible terminals).
+#
+# These capabilities are used by tack(1m), the terminfo action checker
+# (distributed with ncurses 5.0).
+#
+# TABSET FILES
+#
+# All the entries in this file have been edited to assume that the tabset
+# files directory is /usr/share/tabset, in conformance with the File Hierarchy
+# Standard for Linux and open-source BSD systems.  Some vendors (notably Sun)
+# use /usr/lib/tabset or (more recently) /usr/share/lib/tabset.
+#
+# No curses package we know of actually uses these files.  If their location
+# is an issue, you will have to hand-patch the file locations before compiling
+# this file.
+#
+# REQUEST FOR CONTACT INFORMATION AND HISTORICAL MATERIAL
+#
+# As the ANSI/ECMA-48 standard and variants take firmer hold, and as
+# character-cell terminals are increasingly replaced by X displays, much of
+# this file is becoming a historical document (this is part of the reason for
+# the new organization, which puts ANSI types, xterm, Unix consoles,
+# and vt100 up front in confidence that this will catch 95% of new hardware).
+#
+# For the terminal types still alive, I'd like to have manufacturer's
+# contact data (Internet address and/or snail-mail + phone).
+#
+# I'm also interested in enriching the comments so that the latter portions of
+# the file do in fact become a potted history of VDT technology as seen by
+# UNIX hackers.  Ideally, I'd like the headers for each manufacturer to
+# include its live/dead/out-of-the-business status, and for as many
+# terminal types as possible to be tagged with information like years
+# of heaviest use, popularity, and interesting features.
+#
+# I'm especially interested in identifying the obscure entries listed under
+# `Miscellaneous obsolete terminals, manufacturers unknown' before the tribal
+# wisdom about them gets lost.  If you know a lot about obscure old terminals,
+# please go to the terminfo resource page, grab the UFO file (ufo.ti), and
+# eyeball it for things you can identify and describe.
+#
+# If you have been around long enough to contribute, please read the file
+# with this in mind and send me your annotations.

+# California copyright with dates from 1980 to 1993.

+#
+# Not that anyone should care.  However many valid functions copyrights may

+# 16-color linux console entry; this works with a 256-character
+# console font but bright background colors turn into dim ones when
+# you use a 512-character console font. This uses bold for bright
+# foreground colors and blink for bright background colors.
+#
+# Interestingly, the original version of this entry in 2009 used a documented
+# (but nonstandard) SGR 21, which was supported in the Linux console since 1992
+# as an equivalent for SGR 22.  Long after (early 2018), someone modified the
+# console driver to make it ignore SGR 21 because the ECMA-48 standard
+# suggested a different use for that particular code:
+#
+# https://github.com/torvalds/linux/commit/65d9982d7e523a1a8e7c9af012da0d166f72fc56#diff-7da3c215d12c9f6b88e1a37d38b116f0
+#
+# Two years later, someone (unfamiliar with ECMA-48 this time) documented it:
+#
+# https://git.kernel.org/pub/scm/docs/man-pages/man-pages.git/commit/man4/console_codes.4?id=a133a6bc03d751a424fe0a4adea2198757599615

+# Comments in the original are summarized here:
+#
+# hurd uses 8-bit characters (km).
+#
+# Although it doesn't do XON/XOFF, we don't want padding characters (xon).
+#
+# Regarding compatibility to vt100:  hurd doesn't specify <xenl>, as we don't
+# have the eat_newline_glitch.  It doesn't support setting or removing tab
+# stops (hts/tbc).
+#
+# hurd uses ^H instead of \E[D for cub1, as only ^H implements <bw> and it is
+# one byte instead three.
+#
+# <ich1> is not included because hurd has insert mode.
+#
+# hurd doesn't use ^J for scrolling, because this could put things into the
+# scrollback buffer.
+#
+# gsbom/grbom are used to enable/disable real bold (not intensity bright) mode.
+# This is a GNU extension.
+#
+# The original has commented-out ncv, but is restored here.
+#
+# Reading the source, RIS resets cnorm, but not xmous.

+#### SGI consoles
+
+# Sent by Stefan Stapelberg <stefan@rent-a-guru.de>, 24 Feb 1997, this is
+# from SGI's terminfo database.  SGI's entry shows F9-F12 with the codes
+# for the application keypad mode.  We have added iris-ansi-ap rather than
+# change the original to keypad mode.
+#
+# (iris-ansi: added rmam/smam based on init string -- esr)
+#
+# This entry, and those derived from it, is used in xwsh (also known as
+# winterm).  Some capabilities that do not fit into the terminfo model
+# include the shift- and control-functionkeys:
+#
+# F1-F12 generate different codes when shift or control modifiers are used.
+# For example:
+#	F1		\E[001q
+#	shift F1	\E[013q
+#	control-F1	\E[025q
+#
+# In application keypad mode, F9-F12 generate codes like vt100 PF1-PF4, i.e.,
+# \EOP to \EOS.  The shifted and control modifiers still do the same thing.
+#
+# The cursor keys also have different codes:
+#	control-up	\E[162q
+#	control-down	\E[165q
+#	control-left	\E[159q
+#	control-right	\E[168q
+#
+#	shift-up	\E[161q
+#	shift-down	\E[164q
+#	shift-left	\E[158q
+#	shift-right	\E[167q

+# The following terminal descriptions for the  AMD/Intel PC console
+# were prepared  based on information contained in  the OpenBSD-4.9
+# termtypes.master and wscons(4) & vga(4) manuals (2010, November).
+#
+# Added bce based on testing with tack -TD
+# Added several capabilities to pccon+base, reading wsemul_vt100_subr.c -TD
+# Changed kbs to DEL and removed keys that duplicate stty settings -TD
+#
+# Notes from testing with vttest:
+#	fails wrapping test
+#	no 8-bit controls
+#	identifies as vt200 with selective erase, but does not implement DECSCA
+#	no vt52 mode
+#	also lacks these:
+#		ESC # 8	  DEC Screen Alignment Test (DECALN).
+#		CSI ? 5 h Reverse Video (DECSCNM).

+# Andrey Chernov maintains the FreeBSD termcap distributions.
+#
+# Note: Users of FreeBSD 2.1.0 and older versions must either upgrade
+# or comment out the :cb: capability in the console entry.
+#
+# Alexander Lukyanov reports:
+# I have seen FreeBSD-2.1.5R... The old el1 bug changed, but it is still there.
+# Now el1 clears not only to the line beginning, but also a large chunk
+# of previous line. But there is another bug - ech does not work at all.
+
+# syscons, sc - the console driver
+#
+# for syscons
+# common entry without semigraphics
+# Bug: The <op> capability resets attributes.
+# Bug? The ech and el1 attributes appear to move the cursor in some cases; for
+# instance el1 does if the cursor is moved to the right margin first.  Removed
+# by T.Dickey 97/5/3 (ech=\E[%p1%dX, el1=\E[1K)
+#
+# Setting colors turns off reverse; we cannot guarantee order, so use ncv.

+# "The vt(4) system console is automatically selected when booting via UEFI."
+# See FreeBSD #264226.
+#
+# FreeBSD 13 supports 64-bit machines which boot with UEFI:
+#	https://www.freebsd.org/platforms/
+# The i386 platform does not use UEFI (and modifying the loader configuration
+# does load sysconf); however because no updates (fixes) are available, most
+# developers will regard that as unsupported.
+#
+# With FreeBSD 13, even when syscons is loaded (e.g., with the i386 platform),
+# its function-keys are not configured.  Using
+#	vidcontrol -T cons25
+# repairs this.
+#
+# When teken is loaded, vidcontrol can switch at runtime between the
+# teken/cons25 function keys:
+#	vidcontrol -T cons25
+#	vidcontrol -T xterm
+# However due to a limitation in the implementation, only the first 12 function
+# keys are available.  The real syscons supports 48 function keys (using the
+# shift and control modifiers), while xterm supports more than twice as many.
+#
+# vidcontrol does not change the emulation. As a result, the quarter (17/73) of
+# non-function key capabilities which differ between syscons and teken are
+# unsupported in the UEFI-based configurations.
+#
+# tack:
+#	VT100 line-drawing does not work (UTF-8 equivalents do).
+#	Shift/control modifiers have no effect on special keys.
+#	Meta does not work.
+# vttest:
+#	supports REP (repeat).
+#	still does not support left/right margins
+#	SU/SD work, but not SL/SR
+#	alternate screen does not work
+#	ENQ/DA1 is unimplemented (the terminal does not identify itself)
+#	CPR, XCPR are unimplemented (i.e., vttest and resize are broken)
+#	implements X11 (original) xterm-mouse.
+# ncurses:
+#	UTF-8 line-drawing works, including some double/thick lines
+#
+# For FreeBSD 9 and 10:
+# --------------------
+# The /etc/ttys entries for console and other ttys are all configured to set
+# TERM=xterm.
+#
+# Testing with tack:
+# There is no VT100 line-drawing (uses +'s and -'s)
+# Shifted f1-f12 give cons25 codes, rather than xterm function-keys
+#
+# Testing with vttest:
+# Menu 2 diamonds don't work, blink ditto, light background ditto
+# The terminal identifies itself as VT100 with AVO
+# There is no VT52 support
+# There is no doublesize character support
+# The terminal supports ECH (like rxvt)
+# The terminal does not support send/receive mode
+# The terminal supports all of the ISO-6429 cursor-movement
+# The terminal supports some of the ISO-6429 miscellaneous tests
+#	(SL/SR also leave unexpected char on screen too)
+#
+# Considering cons25 as a base, the line-drawing mostly works, but is missing
+# the cells which happen to have ASCII control-character values:
+#	-    ^X    arrow pointing up
+#	.    ^Y    arrow pointing down
+#	i    ^Y    lantern
+#	`    ^D    diamond
+#
+# Those are removed from this entry's acsc string to avoid confusion.

+#### DEC VT100 and compatibles
+#
+# DEC terminals from the VT100 forward are collected here. Older DEC terminals
+# and micro consoles can be found in the `obsolete' section.  More details on
+# the relationship between the VT100 and ANSI X3.64/ISO 6429/ECMA-48 may be
+# found near the end of this file.
+#
+# Except where noted, these entries are DEC's official terminfos.
+# Contact Bill Hedberg <hedberg@hannah.enet.dec.com> of Terminal Support
+# Engineering for more information.  Updated terminfos and termcaps
+# are kept available at ftp://gatekeeper.dec.com/pub/DEC/termcaps.
+#
+# In October 1995 DEC sold its terminals business, including the VT and Dorio
+# line and trademark, to SunRiver Data Systems.  SunRiver has since changed
+# its name to Boundless Technologies; see http://www.boundless.com.
+#
+
+# NOTE:  Any VT100 emulation, whether in hardware or software, almost
+# certainly includes what DEC called the `Level 1 editing extension' codes;
+# only the very oldest VT100s lacked these and there probably aren't any of
+# those left alive.  To capture these, use one of the VT102 entries.
+#
+# Note that the <xenl> glitch in vt100 is not quite the same as on the Concept,
+# since the cursor is left in a different position while in the
+# weird state (concept at beginning of next line, vt100 at end
+# of this line) so all versions of vi before 3.7 don't handle
+# <xenl> right on vt100. The correct way to handle <xenl> is when
+# you output the char in column 80, immediately output CR LF
+# and then assume you are in column 1 of the next line. If <xenl>
+# is on, am should be on too.
+#
+# I assume you have smooth scroll off or are at a slow enough baud
+# rate that it doesn't matter (1200? or less). Also this assumes
+# that you set auto-nl to "on", if you set it off use vt100-nam
+# below.
+#
+# The padding requirements listed here are guesses. It is strongly
+# recommended that xon/xoff be enabled, as this is assumed here.
+#
+# The vt100 uses <rs2> and <rf> rather than <is2>/<tbc>/<hts> because the
+# tab settings are in non-volatile memory and don't need to be
+# reset upon login. Also setting the number of columns glitches
+# the screen annoyingly. You can type "reset" to get them set.
+#
+# The VT100 series terminals have cursor ("arrows") keys which can operate
+# in two different modes: Cursor Mode and Application Mode.  Cursor Mode
+# is the reset state, and is assumed to be the normal state.  Application
+# Mode is the "set" state.  In Cursor Mode, the cursor keys transmit
+# "Esc [ {code}" sequences, conforming to ANSI standards.  In Application
+# Mode, the cursor keys transmit "Esc O <code>" sequences.  Application Mode
+# was provided primarily as an aid to the porting of VT52 applications.  It is
+# assumed that the cursor keys are normally in Cursor Mode, and expected that
+# applications such as vi will always transmit the <smkx> string.  Therefore,
+# the definitions for the cursor keys are made to match what the terminal
+# transmits after the <smkx> string is transmitted.  If the <smkx> string
+# is a null string or is not defined, then cursor keys are assumed to be in
+# "Cursor Mode", and the cursor keys definitions should match that assumption,
+# else the application may fail.  It is also expected that applications will
+# always transmit the <rmkx> string to the terminal before they exit.
+#
+# The VT100 series terminals have an auxiliary keypad, commonly referred to as
+# the "Numeric Keypad", because it is a cluster of numeric and function keys.
+# The Numeric Keypad which can operate in two different modes: Numeric Mode and
+# Application Mode.  Numeric Mode is the reset state, and is assumed to be
+# the normal state.  Application Mode is the "set" state.  In Numeric Mode,
+# the numeric and punctuation keys transmit ASCII 7-bit characters, and the
+# Enter key transmits the same as the Return key (Note: the Return key
+# can be configured to send either LF (\015) or CR LF).  In Application Mode,
+# all the keypad keys transmit "Esc O {code}" sequences.  The PF1 - PF4 keys
+# always send the same "Esc O {code}" sequences.  It is assumed that the keypad
+# is normally in Numeric Mode.  If an application requires that the keypad be
+# in Application Mode then it is expected that the user, or the application,
+# will set the TERM environment variable to point to a terminfo entry which has
+# defined the <smkx> string to include the codes that switch the keypad into
+# Application Mode, and the terminfo entry will also define function key
+# fields to match the Application Mode control codes.  If the <smkx> string
+# is a null string or is not defined, then the keypad is assumed to be in
+# Numeric Mode.  If the <smkx> string switches the keypad into Application
+# Mode, it is expected that the <rmkx> string will contain the control codes
+# necessary to reset the keypad to "Normal" mode, and it is also expected that
+# applications which transmit the <smkx> string will also always transmit the
+# <rmkx> string to the terminal before they exit.
+#
+# Here's a diagram of the VT100 keypad keys with their bindings.
+# The top line is the name of the key (some DEC keyboards have the keys
+# labelled somewhat differently, like GOLD instead of PF1, but this is
+# the most "official" name).  The second line is the escape sequence it
+# generates in Application Keypad mode (where "$" means the ESC
+# character).  The third line contains two items, first the mapping of
+# the key in terminfo, and then in termcap.

+
+#### Terminal.app
+
+# nsterm*|Apple_Terminal - AppKit Terminal.app
+#
+# Terminal.app is a Terminal emulator bundled with NeXT's NeXTSTEP and
+# OPENSTEP/Mach operating systems, and with Apple's Rhapsody, Mac OS X
+# Server and Mac OS X operating systems. There is also a
+# "terminal.app" in GNUstep, but I believe it to be an unrelated
+# codebase and I have not attempted to describe it here.
+#
+# For NeXTSTEP, OPENSTEP/Mach, Rhapsody and Mac OS X Server 1.0, you
+# are pretty much on your own. Use "nsterm-7-m" and hope for the best.
+# You might also try "nsterm-7" and "nsterm-old" if you suspect your
+# version supports color.
+#
+# To determine the version of Terminal.app you're using by running:
+#
+#     echo "$TERM_PROGRAM" "$TERM_PROGRAM_VERSION"
+#
+# For Apple_Terminal v309+, use "nsterm-256color" (or "nsterm-bce")
+#
+# For Apple_Terminal v200+, use "nsterm-16color" (a.k.a. "nsterm")
+#
+# For Apple_Terminal v71+/v100+, use "nsterm-bce".
+#
+# For Apple_Terminal v51+, use "nsterm-7-c" or "nsterm-7-c-s".
+#
+# For Apple_Terminal v41+, use "nsterm-old", or "nsterm-s".
+#
+# For all earlier versions (Apple_Terminal), try "nsterm-7-m"
+# (monochrome) or "nsterm-7" (color); "nsterm-7-m-s" and "nsterm-7-s"
+# might work too, but really you're on your own here since these
+# systems are very obsolete and I can't test them. I do welcome
+# patches, though :).
+
+# Other Terminals:
+#
+# For GNUstep_Terminal, you're probably best off using "linux" or
+# writing your own terminfo.
+
+# For MacTelnet, you're on your own. It's a different codebase, and
+# seems to be somewhere between "vt102", "ncsa" and "xterm-color".
+
+# For iTerm.app, see "iterm".
+
+#
+# The AppKit Terminal.app descriptions all have names beginning with
+# "nsterm". Note that the statusline (-s) versions use the window
+# titlebar as a phony status line, and may produce warnings during
+# compilation as a result ("tsl uses 0 parameters, expected 1".)
+# Ignore these warnings, or even ignore these entries entirely. Apps
+# which need to position the cursor or do other fancy stuff inside the
+# status line won't work with these entries. They're primarily useful
+# for programs like Pine which provide simple notifications in the
+# status line. Please note that non-ASCII characters don't work right
+# in the status line, since Terminal.app incorrectly interprets their
+# Unicode codepoints as MacRoman codepoints (in earlier Mac OS X
+# versions) or only accepts status lines consisting entirely of
+# characters from the first 256 Unicode positions (including C1 but
+# not C0 or DEL.)
+#
+# The Mythology* of AppKit Terminal.app:
+#
+# In the days of NeXTSTEP 0.x and 1.x there were two incompatible
+# bundled terminal emulators, Shell and Terminal. Scott Hess wrote a
+# shareware replacement for Terminal called "Stuart" which NeXT bought
+# and used as the basis for the Terminal.app in NeXTSTEP 2+,
+# OPENSTEP/Mach, Apple Rhapsody, Mac OS X Server 1.0, and Mac OS X. I
+# don't know the TERM_PROGRAM and TERM_PROGRAM_VERSION settings or
+# capabilities for the early versions, but I believe that the
+# TERM_PROGRAM_VERSION may have been reset at some point.
+#
+# The early versions were tailored to the NeXT character set. Sometime
+# after the Apple acquisition the encoding was switched to MacRoman
+# (initially with serious altcharset bugs due to incomplete conversion
+# of the old NeXT code,) and then later to UTF-8. Also sometime during
+# or just prior to the early days of Mac OS X, the Terminal grew ANSI
+# 8-color support (initially buggy when combined with attributes, but
+# that was later fixed.) More recently, around Mac OS X version 10.3
+# or so (Terminal.app v100+) xterm-like 16-color support was added. In
+# some versions (for instance 133-1 which shipped with Mac OS X
+# version 10.4) this suffered from the <bce> bug, but that seems to
+# have been fixed in Mac OS X version 10.5 (Terminal.app v240.2+).
+#
+# In the early days of Mac OS X the terminal was fairly buggy and
+# would routinely crash under load. Many of these bugs seem to have
+# been fixed around Mac OS X version 10.3 (Terminal.app v100+) but
+# some may still remain. This change seems to correspond to
+# Terminal.app reporting "xterm-color" as $TERM rather than "vt100" as
+# it did previously.
+#
+# * This may correspond with what actually happened, but I don't
+#   know. It is based on guesswork, hearsay, private correspondence,
+#   my faulty memory, and the following online sources and references:
+#
+# [1] "Three Scotts and a Duane" by Simson L. Garfinkel
+# http://www.nextcomputers.org/NeXTfiles/Articles/NeXTWORLD/93.8/93.8.Dec.Community1.html
+#
+# [2] NeXTSTEP entry from Wikipedia, the free encyclopedia
+# https://secure.wikimedia.org/wikipedia/en/wiki/Nextstep
+#
+# * Renamed the AppKit Terminal.app entry from "Apple_Terminal" to
+#   "nsterm" to comply with the name length and case conventions and
+#   limitations of various software packages [notably Solaris terminfo
+#   and UNIX.] A single Apple_Terminal alias is retained for
+#   backwards-compatibility.
+#
+# * Added function key support (F1-F4). These only work in Terminal.app
+#   version 51, hopefully the capabilities won't cause problems for people
+#   using version 41.
+#
+# * Added "full color" (-c) entries which support the 16-color mode in
+#   version 51.
+#
+# * By default, version 51 uses UTF-8 encoding with broken altcharset
+#   support, so "ASCII" (-7) entries without altcharset support were
+#   added.
+
+# nsterm - AppKit Terminal.app
+#
+# Apple's Mac OS X includes a Terminal.app derived from the old NeXT
+# Terminal.app. It is a partial VT100 emulation with some xterm-like
+# extensions. This terminfo was written to describe versions 41
+# (shipped with Mac OS X version 10.0) and 51 (shipped with Mac OS X
+# version 10.1) of Terminal.app.
+#
+# Terminal.app runs under the Mac OS X Quartz windowing system (and
+# other AppKit-supported windowing systems.)  On the Mac OS X machine I
+# use, the executable for Terminal.app is:
+# /Applications/Utilities/Terminal.app/Contents/MacOS/Terminal
+#
+# If you're looking for a description of the full-screen system
+# console which runs under Apple's Darwin operating system on PowerPC
+# platforms, see the "xnuppc" entry instead.
+#
+# There were no function keys in version 41. In version 51, there are
+# four working function keys (F1, F2, F3 and F4.) The function keys
+# are included in all of these entries.
+#
+# It does not support mouse pointer position reporting. Under some
+# circumstances the cursor can be positioned using option-click; this
+# works by comparing the cursor position and the selected position,
+# and simulating enough cursor-key presses to move the cursor to the
+# selected position. This technique fails in all but the simplest
+# applications.
+#
+# It provides partial ANSI color support (background colors interacted
+# badly with bold in version 41, though, as reflected in :ncv:.) The
+# monochrome (-m) entries are useful if you've disabled color support
+# or use a monochrome monitor. The full color (-c) entries are useful
+# in version 51, which doesn't exhibit the background color bug. They
+# also enable an xterm-compatible 16-color mode.
+#
+# The configurable titlebar is set using xterm-compatible sequences;
+# it is used as a status bar in the statusline (-s) entries. Its width
+# depends on font sizes and window sizes, but 50 characters seems to
+# be the default for an 80x24 window.
+#
+# The MacRoman character encoding is used for some of the alternate
+# characters in the "MacRoman" entries; the "ASCII" (-7) entries
+# disable alternate character set support entirely, and the "VT100"
+# (-acs) entries rely instead on Terminal.app's own buggy VT100
+# graphics emulation, which seems to think the character encoding is
+# the old NeXT charset instead of MacRoman. The "ASCII" (-7) entries
+# are useful in Terminal.app version 51, which supports UTF-8 and
+# other ASCII-compatible character encodings but does not correctly
+# implement VT100 graphics; once VT100 graphics are correctly
+# implemented in Terminal.app, the "VT100" (-acs) entries should be
+# usable in any ASCII-compatible character encoding [except perhaps
+# in UTF-8, where some experts argue for disallowing alternate
+# characters entirely.]
+#
+# Terminal.app reports "vt100" as the terminal type, but exports
+# several environment variables which may aid detection in a shell
+# profile (i.e. .profile or .login):
+#
+# TERM=vt100
+# TERM_PROGRAM=Apple_Terminal
+# TERM_PROGRAM_VERSION=41      # in Terminal.app version 41
+# TERM_PROGRAM_VERSION=51      # in Terminal.app version 51
+#
+# For example, the following Bourne shell script would detect the
+# correct terminal type:
+#
+# if [ :"$TERM" = :"vt100" -a :"$TERM_PROGRAM" = :"Apple_Terminal" ]
+# then
+#     export TERM
+#     if [ :"$TERM_PROGRAM_VERSION" = :41 ]
+#     then
+#         TERM="nsterm-old"
+#     else
+#         TERM="nsterm-c-7"
+#     fi
+# fi
+#
+# In a C shell derivative, this would be accomplished by:
+#
+# if ( $?TERM && $?TERM_PROGRAM && $?TERM_PROGRAM_VERSION) then
+#     if ( :"$TERM" == :"vt100" && :"$TERM_PROGRAM" == :"Apple_Terminal" ) then
+#          if ( :"$TERM_PROGRAM_VERSION" == :41 ) then
+#              setenv TERM "nsterm-old"
+#          else
+#              setenv TERM "nsterm-c-7"

+#   the menu says "Declare terminal as" without promising to actually emulate
+#   the corresponding terminals.  Indeed, changing TERM does not affect the
+#   emulation itself.  This means that
+#   + the function-keys do not match for dtterm for kf1-kf4 as well as
+#     khome/kend
+#   + the color model is the same for each setting of TERM (does not match

+#     does not work as expected.
+#   + selecting "xterm" or "xterm-16color" sets TERM to "xterm-256color".
+# + OSX 10.9 (Yosemite) added more extended keys in the default configuration
+#   as well as unmasking F10 (which had been used in the window manager). Those
+#   keys are listed in this entry.

+# xnuppc - Darwin PowerPC Console (a.k.a. "darwin")
+#
+# On PowerPC platforms, Apple's Darwin operating system uses a
+# full-screen system console derived from a NetBSD framebuffer
+# console. It is an ANSI-style terminal, and is not really VT-100
+# compatible.
+#
+# Under Mac OS X, this is the system console driver used while in
+# single-user mode [reachable by holding down Command-S during the
+# boot process] and when logged in using console mode [reachable by
+# typing ">console" at the graphical login prompt.]
+#
+# If you're looking for a description of the Terminal.app terminal
+# emulator which runs under the Mac OS X Quartz windowing system (and
+# other AppKit-supported windowing systems,) see the "nsterm"
+# entry instead.
+#
+# NOTE: Under Mac OS X version 10.1, the default login window does not
+# prompt for user name, instead requiring an icon to be selected from
+# a list of known users. Since the special ">console" login is not in
+# this list, you must make one of two changes in the Login Window
+# panel of the Login section of System Prefs to make the special
+# ">console" login accessible. The first option is to enable 'Show
+# "Other User" in list for network users', which will add a special
+# "Other..." icon to the graphical login panel. Selecting "Other..."
+# will present the regular graphical login prompt. The second option
+# is to change the 'Display Login Window as:' setting to 'Name and
+# password entry fields', which replaces the login panel with a
+# graphical login prompt.
+#
+# There are no function keys, at least not in Darwin 1.3.
+#
+# It has no mouse support.
+#
+# It has full ANSI color support, and color combines correctly with
+# all three supported attributes: bold, inverse-video and underline.
+# However, bold colored text is almost unreadable (bolding is
+# accomplished using shifting and or-ing, and looks smeared) so bold
+# has been excluded from the list of color-compatible attributes
+# [using (ncv)]. The monochrome entry (-m) is useful if you use a
+# monochrome monitor.
+#
+# There is one serious bug with this terminal emulation's color
+# support: repositioning the cursor onto a cell with non-matching
+# colors obliterates that cell's contents, replacing it with a blank
+# and displaying a colored cursor in the "current" colors. There is
+# no complete workaround at present [other than using the monochrome
+# (-m) entries,] but removing the (msgr) capability seemed to help.
+#
+# The "standout" chosen was simple reverse-video, although a colorful
+# standout might be more aesthetically pleasing. Similarly, the bold
+# chosen is the terminal's own smeared bold, although a simple
+# color-change might be more readable. The color-bold (-b) entries
+# uses magenta colored text for bolding instead. The fancy color (-f
+# and -f2) entries use color for bold, standout and underlined text
+# (underlined text is still underlined, though.)
+#
+# Apparently the terminal emulator does support a VT-100-style
+# alternate character set, but all the alternate character set
+# positions have been left blank in the font. For this reason, no
+# alternate character set capabilities have been included in this
+# description. The console driver appears to be ASCII-only, so (enacs)
+# has been excluded [although the VT-100 sequence does work.]
+#
+# The default Mac OS X and Darwin installation reports "vt100" as the
+# terminal type, and exports no helpful environment variables. To fix
+# this, change the "console" entry in /etc/ttys from "vt100" to
+# "xnuppc-WxH", where W and H are the character dimensions of your
+# console (see below.)
+#
+# The font used by the terminal emulator is apparently one originally
+# drawn by Ka-Ping Yee, and uses 8x16-pixel characters. This
+# file includes descriptions for the following geometries:
+#
+#     Pixels        Characters   Entry Name (append -m for monochrome)

+#### PuTTY
+# PuTTY 0.74 (27 June 2020)
+# http://www.chiark.greenend.org.uk/~sgtatham/putty/
+#
+# PuTTY 0.73 (September 2019)
+# Testing with tack:
+#	does not implement italics
+#	does not implement cross-out text
+#	its settings dialog allows some of the VT100 line-drawing tests to pass
+#	(not the padding test, though)
+# Testing with vttest:
+#	xterm mouse modes are incomplete: X10, highlight, any-event, and focus in/out modes are not implemented.
+#	does not implement protected areas
+#	does not implement SL/SR
+#
+# PuTTY 0.71 (March 2019) provided a workable "rep" capability.  It also
+# changed longstanding keypad assignments, so that these no longer apply:
+#	kLFT=\E[D, kRIT=\E[C, kb2=\E[G,
+#
+# PuTTY recognized xterm's 1006 mouse mode in late 2015; subsequent release was
+# in 2017 (0.70) -TD
+#
+# Comparing with 0.51, vttest is much better (only a few problems with the
+# cursor position reports and wrapping).
+#
+# PuTTY 0.51 (14 December 2000)
+#
+# This emulates VT100 + VT52 (plus a few VT220 features:  ech, SRM, DECTCEM, as
+# well as SCO and Atari, color palettes from Linux console).  Reading the code,
+# it is intended to be VT102 plus selected features.  By default, it sets $TERM
+# to xterm, which is incorrect, since several features are misimplemented:
+#
+#	Alt+key always sends ESC+key, so 'km' capability is removed.
+#
+#	Control responses, wrapping and tabs are buggy, failing a couple of
+#	screens in vttest.
+#
+#	xterm mouse support is not implemented (unreleased version may).
+#
+# Several features such as backspace/delete are optional; this entry documents
+# the default behavior.  None of the combinations of keyboard settings match
+# those used for xterm -TD
+#
+# PuTTY recognizes xterm's 1049 mode for switching to/from alternate screen,
+# but implements it incorrectly as mentioned here:

+# Originally a fork (and reduction) of PuTTY, this has grown from 15ksloc in
+# 2013 to 41ksloc in 2020.  That is still smaller than PuTTY (160ksloc), but
+# larger than rxvt (31ksloc) and slightly smaller than rxvt-unicode (42ksloc).
+#
+# Version 3.0 responds to DA as a VT400, however it does not implement the
+# application keypad.  The assignment of cursor-keys versus modifiers differs
+# from xterm (alt-left and alt-right send modifier 7, i.e., alt+control).
+#
+# Thomas Wolff suggested these extensions:
+#	blink2   turn on rapid blinking
+#	blink0   turn off blinking
+#	norm     turn off bold and half-bright mode
+#	opaq     turn off blank mode
+#	smul2    begin double underline mode
+#	smol     begin overline mode
+#	rmol     exit overline mode
+#	Font0    use default font
+#	Font1    use alternative font 1
+#	...
+#	Font10   use alternative font 10
+#	setal    set (under)line color
+#	ol       set default (under)line color
+#	overs    overstrike (print characters over each other)
+#
+# but see vte-2018 (use Smol/Rmol rather than smol/rmol).

+#### TeraTerm
+
+# This entry is for Tera Term Pro version 2.3, for MS-Windows 95/NT written by
+# T. Teranishi dated Mar 10, 1998.  It is a free software terminal emulator
+# (communication program) which supports:
+#
+#	- Serial port connections.
+#	- TCP/IP (telnet) connections.
+#	- VT100 emulation, and selected VT200/300 emulation.
+#	- TEK4010 emulation.
+#	- File transfer protocols (Kermit, XMODEM, ZMODEM, B-PLUS and
+#	  Quick-VAN).
+#	- Scripts using the "Tera Term Language".
+#	- Japanese and Russian character sets.
+#
+# The program does not come with terminfo or termcap entries.  However, the
+# emulation (testing with vttest and ncurses) is reasonably close to VT100 (no
+# VT52 or doublesize character support; blinking is done with color).  Besides
+# the HPA, VPA extensions it also implements CPL and CNL.
+#
+# All of the function keys can be remapped.  This description shows the default
+# mapping, as installed.  Both VT100 PF1-PF4 keys and quasi-vt220 F1-F4 keys
+# are supported.  F13-F20 are obtained by shifting F3-F10.  The editing keypad
+# is laid out like VT220, rather than the face codes on the PC keyboard, i.e,
+#	kfnd	Insert
+#	kslt	Delete
+#	kich1	Home
+#	kdch1	PageUp
+#	kpp	End
+#	knp	PageDown
+#
+# ANSI colors are implemented, but cannot be combined with video attributes
+# except for reverse.
+#
+# No fonts are supplied with the program, so the acsc string is chosen to
+# correspond with the default Microsoft terminal font.
+#
+# Tera Term recognizes some xterm sequences, including those for setting and
+# retrieving the window title, and for setting the window size (i.e., using
+# "resize -s"), though it does not pass SIGWINCH to the application if the
+# user resizes the window with the mouse.

+# - does not support numeric keypad application mode.
+# - control-modifier (without alt/shift) does not work for special keys.

+# copied the earlier scheme, as noted in the "use=" clauses in this file.
+#
+# The original assignments from patch #94 for cursor-keys had some technical
+# issues:
+#
+#	A parameter for a function-key to represent a modifier is just more
+#	bits.  But for a cursor-key it may change the behavior of the
+#	application.  For instance, emacs decodes the first parameter of a
+#	cursor-key as a repeat count.
+#
+#	A parameterized string should (really) not begin with SS3 (\EO).
+#	Rather, CSI (\E[) should be used.
+#
+# For these reasons, the original assignments were deprecated.  For
+# compatibility reasons, they are still available as a setting of xterm's
+# modifyCursorKeys resource.  These fragments list the modified cursor-keys
+# that might apply to xterm+pcfkeys with different values of that resource.
+#
+# These entries will have warnings when checking with tic because the kri/kind

+# Xterm's emulation of the VT100 numeric keypad on a PC-keyboard runs into the
+# problem that the keypad layout is different, and that the natural choice for
+# PF1 is NumLock (which happens to be reserved for other use).  To work around
+# that, PF1-PF4 are emulated via F1-F4, which leaves the "/", "*" and "+" not
+# directly related to VT100.
+#
+# With the VT220 keypad block that uses the 1-9 keys as suggested in
+# terminfo(5), the other keys can be handled with user-defined capabilities:

+#### XTERM Features
+
+# This chunk is based on suggestions by Ailin Nemui and Nicholas Marriott, who
+# asked for some of xterm's advanced features to be added to its terminfo
+# entry.  It defines extended capabilities not found in standard terminfo or
+# termcap.  These are useful in tmux, for instance, hence the name.
+#
+# One caveat in adding extended capabilities in ncurses is that if the names
+# are longer than two characters, then they will not be visible through the
+# termcap interface.
+#
+# Ms modifies the selection/clipboard.  Its parameters are
+#	p1 = the storage unit (clipboard, selection or cut buffer)
+#	p2 = the base64-encoded clipboard content.
+#
+# Ss is used to set the cursor style as described by the DECSCUSR
+#	function to a block or underline.
+# Se resets the cursor style to the terminal power-on default.
+#
+# Cs and Cr set and reset the cursor colour.

+# b) the "0" code for xterm updates both icon-title and window title.  Some

+#    it such as tvtwm, ctwm, and vtwm) track windows by icon-name. Thus, you
+#    don't want to mess with icon-name when using those window managers.

+#    may cause the escape sequence to end with an error.
+# d) the BEL (^G or \007) used in the original title-as-statusline came from

+#### XTERM Mouse
+# The xterm mouse protocol is used by other terminal emulators.
+# In this section, two extended capabilities are used to illustrate the mouse
+# protocol: XM and xm.  The "XM" capability is recognized by ncurses to allow
+# enabling/disabling other mouse protocols.  The "xm" capability describes the
+# mouse response; currently there is no interpreter which would use this
+# information to make the mouse support completely data-driven.
+
+# Here is the "original" xterm mouse protocol.
+#
+# First seen in X10.3, February 1986, this likely dates from 1985 based on the
+# copyright dates in the sources.  A comment in charproc.c notes "MIT bogus
+# sequence", referring to the fact that it does not correspond to a "real"
+# terminal.  The mouse responses for the X10 protocol are sent only for

+
+# Here is the conventional xterm mouse protocol, introduced with X11R1 in
+# September 1987.
+#
+# The mouse responses for the X11 protocol covered button releases, as well as
+# modifiers:
+#  shift    4
+#  alt/meta 8 (technically the "mod1" mask, because X11 has no such keys)
+#  control 16
+#
+# The modifiers are not reflected in this description because as used in xterm
+# they are normally inaccessible because the translations resources assign
+# shift and control to other features.  However, they are important because
+# they take up space in the first byte of the response.  The other bits of this
+# byte are used to encode the button number for both presses and releases.
+# In the X11 protocol, any button-release is encoded with "3" (the lowest 2
+# bits in the byte).  Later work on XFree86 xterm used the remaining 3 bits to
+# provide additional features, e.g., wheel mouse.
+#
+# X11R1's xterm also supported an "emacs" mouse protocol, with final character
+# "t" or "T", which was activated by double-clicking.  The "t" response was
+# used when the starting/ending positions were the same.
+#
+# X11R3 (February 1988) added the highlight/tracking mode.
+#
+# X11R4 (December 1989) added the control sequences document, listing the
+# control sequences for the X10/X11 protocols without descriptions.  It also
+# mentioned the "emacs" ("T") response.  Comments in button.c referred to the
+# X11 protocol as "DEC VT200 compatible", although DEC offered no such terminal.
+#
+# X11R5 (November 1993) gave a description of the mouse protocol.
+#
+# X11R6 (January 1995) moved the control sequences document out of the xterm

+# Originally VTE was promoted as a library able to emulate any terminal by
+# reading its terminal description.  In practice, that never got beyond the
+# ability to read definitions of special keys (function-, editing-, cursor).
+#
+# Before 2014, VTE had a termcap reader (originally pointing to a private copy
+# of a termcap file derived from xterm).  That was incomplete because it did
+# not have any of the modifier-key information used for xterm's function-,
+# editing-, and cursor-keys.  Having its own reader was unnecessary since
+# ncurses provides that information; used since xterm patch #225 in 2007.
+#
+# During April/May 2014, a few bug reports (e.g., gnome #169295, gnome #728900,
+# gnome #730137) dealt with attempts to recast that termcap reader as library
+# calls, then attempting to adapt a chunk of code from ncurses (src/vteti.c),
+# abandoning that and finally constructing a table to match xterm's default
+# behavior, e.g., for "xterm+pcfkeys".

+# (formerly known as kvt)
+#
+# This program hardcodes $TERM to 'xterm', which is not accurate.  However, to
+# simplify this entry (and point out why konsole isn't xterm), we base this on
+# xterm-r6.  The default keyboard appears to be 'linux'.
+#
+# Notes:
+# a) konsole implements several features from XFree86 xterm, though none of
+#    that is documented - except of course in its source code - apparently
+#    because its implementors are unaccustomed to reading documentation - as
+#    evidenced by the sparse and poorly edited documentation distributed with
+#    konsole.  Some features such as the 1049 private mode are recognized but
+#    incorrectly implemented as a duplicate of the 47 private mode.
+# b) even with the "vt100 (historical)" keyboard setting, the numeric keypad
+#    sends PC-style escapes rather than VT100.
+# c) fails vttest menu 3 (Test of character sets) because it does not properly
+#    parse some control sequences.  Also fails vttest Primary Device Attributes
+#    by sending a bogus code (in the source it says it's supposed to be a
+#    VT220, which is doubly incorrect because it does not implement VT220
+#    control sequences except for a few special cases).  Treat it as a
+#    mildly-broken VT102.
+#
+# Update for konsole 1.3.2:
+#    The 1049 private mode works (but see the other xterm screens in vttest).
+#    Primary Device Attributes now returns the code for a VT100 with advanced
+#    video option.  Perhaps that's intended to be a "mildly-broken Vt102".
+#
+# Updated for konsole 1.6.4:
+#    add konsole-solaris
+#
+# Updated for konsole 1.6.6:
+#    add control-key modifiers for function-keys, etc.
+#
+# Updated for konsole 2.3 (October 2008):
+#    vttest menu 1 shows that both konsole and gnome terminal do wrapping
+#    different from xterm (and VT100's).  They have the same behavior in
+#    this detail, but it is unclear which copies the other.
+#
+# Deferred update for konsole 2.10 (late 2012):

+# The keytab feature was introduced in 0.9.12 (February 2000) with "linux" and
+# "vt100" key-table files along with a compiled-in default key-table.
+#
+# The main difference between the two keytabs was that the developer equated
+# "vt100" with xterm, and noticed that the Linux console's F1-F5 differed from
+# that.  For the same reason, the home/end keys differ.  A VT100 had none of
+# that.  The otherwise identical keytabs have definitions to model the VT52
+# cursor-keys and the VT100 cursor-keys with application versus normal modes.
+#
+# An "x11r5" keytab (displayed in the menu as "X11 R5") was added in January
+# 2001, and shortly after retitled to "XFree 3.x.x".  Both it and "vt100" were
+# dropped from the install in June 2008.
+#
+# The default keytab added in January 2000 was originally titled "X11 R6",
+# and likewise retitled to "XFree 4".
+#
+# A "solaris" keytab was added in Febrary 2005, copying the "vt100" keytab
+# and changing backspace to ^H, removing that keytab's attempt to model the
+# VT100 keypad and VT52 (KDE #20459).
+#
+# The developers made changes to the default and linux keytabs.  Comparing
+# the original and 2018 versions using diffstat:
+#	default: 119 added, 147 deleted, 28 unchanged
+#	linux:   47 added, 28 deleted, 104 unchanged
+#
+# Most of the change for the default keytab was to make konsole act more like
+# xterm.  That was a feature named AnyMod which came in May 2005 for KDE #92749
+# (see also Redhat #122815).  Later, in June 2007 the compiled-in keytab was
+# made an external file (like "linux" and "solaris"), and some further
+# refinement made.  But there are still flaws in the scheme.
+#
+# Essentially AnyMod maps the xterm "PC-style" modifier codes such as 2 for
+# Shift into a placeholder in the table entries.  That works well if all of the
+# modified keys are modified in the same way.  But xterm does not do that.  The
+# first 4 function keys are used in xterm to support the VT100 PF1-PF4 keypad
+# keys.  For example, F2 sends \EOQ in both terminals because of this feature.
+# But a shifted F2 (F14=F2+12) differs like this, in infocmp's listing:
+#	kf14: '\E[1;2Q', '\EO2Q'.
+#
+# In effect, a quarter of konsole's function-keys are different from xterm.
+#
+# It is not a simple blunder:
+# a) xterm patch #121 (November 1999), providing the first version of the
+#    PC-style modifiers would send \EO2Q
+# b) xterm patch #216 (July 2006) amended this and other details, provided
+#    better documentation for the modifiers and made the behavior configurable,
+#    e.g., using the modifyFunctionKeys resource.  The reason why it sends
+#    \E[1;2Q is that \E[O2Q is not a legal ECMA-48 control sequence.  The
+#    changelog points this out as "avoid sending SS3 with parameters".
+# c) That came after AnyMod was introduced, but still early enough that one
+#    might expect konsole's developers to followup.  Twelve years later that
+#    has yet to happen.
+#
+# As of 2018, konsole still provides 3 keyboard profiles ("XFree 4", "linux",

+# Updated: Oezguer Kesim <kesim@math.fu-berlin.de> 02 Nov 1997
+# Notes:
+# rxvt 2.21b uses
+#	smacs=\E(B\E)U^N, rmacs=\E(B\E)0^O,
+# but some applications don't work with that.
+# It also has an AIX extension
+#	box2=lqkxjmwuvtn,
+# and
+#	ech=\E[%p1%dX,
+# but the latter does not work correctly.
+#
+# The distributed terminfo says it implements hpa and vpa, but they are not
+# implemented correctly, using relative rather than absolute positioning.
+#
+# rxvt is normally configured to look for "xterm" or "xterm-color" as $TERM.
+# Since rxvt is not really compatible with xterm, it should be configured as
+# "rxvt" or "rxvt-color".
+#
+# removed dch/dch1 because they are inconsistent with bce/ech -TD

+# Though its change-log does not mention this, John Davis has stated that he
+# was the author of the changes to use the bce ("new color model") which was
+# incorporated into rxvt 2.11 (June 15, 1995).  The change-log does not give
+# dates, nor give developer's names.  Initial color support was added for rxvt
+# "2.0", which was sometime in 1994.
+#
+# rxvt had usable color support with 2.16 (April 2, 1996), with some help by my
+# work on vttest, as well as bug reports to Mark Olesen.  For instance, the fix
+# mentioned here
+#	https://web.archive.org/web/20141016124430/http://web.archiveorange.com/archive/v/6ETvLb5wHtbbzCaS4S9J
+# was from one of my bug-reports -TD
+#
+# While the color model both for xterm and rxvt was based on Linux console,
+# Olesen (or possibly Davis) diverged in one respect from Linux's bce color
+# behavior: inserting/deleting characters does not fill the newly empty cell
+# with the default background color.

+#
+# Testing with tack:

+#
+# Testing with vttest:
+# +	While "based on" rxvt, some of the basic functionality is broken.  The
+#	window collapses to a single line when running several of the screens
+#	in vttest, e.g., the tests for cursor movement, screen features,
+#	double-sized characters.
+# +	The VT52 test works properly, but this is an exception.  Due to the
+#	other bug(s) most of vttest is untestable.
+# +	the color test using ECH shows a gap in the bce model, like rxvt.
+#
+# Testing with xterm "vttest" scripts:
+# +	resize.pl does not work because mrxvt does implement CSI 18 t
+#	(not in rxvt, but not documented by mrxvt) but not CSI 19 t.

+#### TERMINATOR
+# https://github.com/software-jessies-org/jessies/wiki/Terminator
+#
+# Tested using the Debian package org.jessies.terminator 6.104.3256 on 64-bit
+# Debian/current -TD (2011/8/20)
+#
+# There were some packaging problems:
+# a) using Java, the program starts off using 50Mb, and climbs from there,
+#    up to 114Mb after testing (no scrollback).
+# b) it insists on reinstalling its terminal description in $HOME/.terminfo
+#    (two copies, just in case the host happens to be Mac OS X).
+#    I deleted this after testing with tack.
+#
+# Issues/features found with tack:
+# a) tbc does not work (implying that hts also is broken).
+#    Comparing with the tabs utility shows a problem with the last tabstop on
+#    a line.
+# b) has xterm-style shifted function-key strings
+#    meta also is used, but control is ignored.
+# c) has xterm-style modifiers for cursor keys (shift, control, shift+control,
+#    meta)
+# d) some combinations of shift/control send xterm-style sequences for
+#    insert/delete/home/end.
+# e) numeric keypad sends only numbers (compare with vttest).
+# f) meta mode (km) is not implemented.
+#
+# Issues found with ncurses test-program:
+# a) bce is inconsistently implemented
+# b) widths of Unicode values above 256 do not always agree with wcwidth.
+#
+# Checked with vttest, found low degree of compatibility there.
+#
+# Checked with xterm's scripts, found that the 256-color palette is fixed.
+#
+# Fixes:
+# a) add sgr string
+# b) corrected sgr0 to reset alternate character set
+# c) modified smacs/rmacs to use SCS rather than SI/SO
+# d) removed bce
+# e) removed km
+#
+# Revisiting in May 2019, the Debian package was no longer available, and a
+# developer-provided ".deb" does not work.  However, a usable Windows ".msi"
+# (which relies upon Cygwin) can be tested.  The developers provide a terminfo,
+# but some of the features it lists do not work reliably (bce, italics, invis).
+#
+# tack:
+#	tbc fails
+#	invis attribute fails
+#	key-definitions could be expanded, with some work:
+#	+ supports xterm-style cursor key-modifiers for shift
+#	+ supports xterm-style function key-modifiers for shift,control,alt

+#	window modify/report operations do not work
+#	miscellaneous ISO-6429 tests, e.g., REP, do not work
+#	CBT, CHT, HPR, CNL,CPL, VPR do not work

+#
+# General comments:
+#	cursor does not fill on focus

+#	resizing the window causes it to stop listening to the keyboard
+# tack -
+#	doesn't understand VT100 CPR needed for resize
+#	no CBT
+#	no cvvis
+#	has invis
+#	no blink
+#	uses bce model for colors, but (see below) fails the vttest screens
+#	has partial support for 256color feature.
+#	tack function-keys (a subset of xterm+pcf0), and
+#	tack cursor-keys (a subset of xterm+pce2):
+#			ctrl+shift (ignored)
+#		2	shift
+#			shift-alt modifier -> shift (2)
+#		3	alt
+#		4
+#		5	ctrl
+#	tack modifiers did not work for fkeys in 0.3.0; subset works in 0.6.1
+#	ctrl + khome/kend works - none of the other modifiers do
+# vttest -
+#	spits lots of messages from termptyesc.c especially in vttest.
+#	no 132-column mode
+#	fails menu 1, 2 (definitely not VT100-compatible)
+#	primary (claims VT420 with several options, apparently none work) and

+#	BCE with ED/EL - fail
+#	BCE with ECH/indexing - fail
+#	SD/SU work

+# https://github.com/kovidgoyal/kitty
+# Project started in 2016/10 (see alacritty), but is a Python script rather

+#	Repeatable tests with tack and vttest assume a standard screensize --
+#	measured in characters.  However, kitty uses pixel-measurements and
+#	does not readily use characters.
+#	Resizing with twm shows only pixel-based hint rather than characters
+#	manual page states that it is possible to override initial window size,
+#	but configuration file has no effect on initial window size.
+#	The same problem with XFCE4, but editing the cached json file works
+#	for setting the window size (the "c" suffix for cells does not):
+#		{"window-size": [720, 440]}
+#	though the values depend upon the font in use.

+#### Screen
+
+# Entries for use by the `screen' program by Juergen Weigert,
+# Michael Schroeder, Oliver Laumann.  The screen and
+# screen-w entries came with version 3.7.1.  The screen2 and screen3 entries
+# come from University of Wisconsin and may be older.
+# (screen: added <cnorm> on ANSI model -- esr)
+#
+# 'screen' defines extensions to termcap.  Some are used in its terminal
+# description:
+#      G0   (bool)  Terminal can deal with ISO 2022  font  selection sequences.
+#      AX   (bool)  Does  understand ANSI set default fg/bg color
+#                   (\E[39m / \E[49m).
+#      S0   (str)   Switch charset 'G0' to the specified charset.
+#      E0   (str)   Switch charset 'G0' back to standard charset.
+#
+# Initially tested with screen 3.09.08
+#
+# According to its manual page
+#
+#      Screen is a full-screen window manager that multiplexes a physical
+#      terminal between several processes (typically interactive shells).  Each
+#      virtual terminal provides the functions of a DEC VT100 terminal and, in
+#      addition, several control functions from the ISO 6429 (ECMA 48, ANSI
+#      X3.64) and ISO 2022 standards (e.g.  insert/delete line and support for
+#      multiple character sets).
+#
+# However, there is a design error in its support for video highlights.  The
+# program uses a table (rendlist) which equates the SGR codes to terminal
+# capabilities.  That, and color-decoding are hardcoded in screen; its behavior
+# is modified only by the presence or absence of the corresponding capabilities.
+# Not by their values.
+#
+# If screen sets the TERMCAP variable, it uses hardcoded strings which
+# correspond to the rendlist table.
+#
+# The table gives this information:
+#
+#	SGR	capability
+#	---	---------
+#	1	bold
+#	2	dim
+#	3	standout
+#	4	underline
+#	5	blink
+#	-	(unused 6)
+#	7	reverse
+#	-	(unused 8-21)
+#	22	reset bold, standout and dim
+#	23	reset standout
+#	24	reset underline
+#	25	reset blink
+#	-	(unused 26)
+#	27	reset reverse
+#
+# ECMA-48 differs from this: 3 and 23 set and reset italics, respectively.
+# ECMA-48 does not define "standout" - that is a termcap/terminfo abstraction.
+# Without some redesign of screen, it is not possible to extend the set of
+# capabilities.  Substitution would be possible, e.g., sending italics in
+# place of underline.
+#
+# Because screen uses hard-coded parsing, it does not check if two capabilities
+# use the same value.  For example, changing standout to be the same as any of
+# the other capabilities will confuse screen.  Curses applications which use
+# sgr are not impacted (because that usually resets all capabilities before
+# setting any), but termcap applications do not use sgr -TD
+#
+# The "screen" entry should use ecma+index rather than just indn, but tmux
+# defaults to using "screen".  For background, screen supported ecma+index
+# since 1994 (i.e., screen 3.0.5), stating that it was an obscure code used by
+# the (Siemens Nixdorf) 97801 terminal.  It was not shown in the termcap or
+# terminfo entries (which list about 60% of the control sequences).

+#### Mosh
+# https://mosh.org/
+# mosh 1.3.2
+#
+# mosh's DA1 identifies it as a VT220, but sets $TERM to "xterm" or
+# "xterm-256color" (hard-coded), which in its pretense that it is xterm, is
+# several years out of date.
+#
+# There is little documentation; the existing manpages amount to a quarter of
+# the length of mosh.org's heavily promotional website.  This entry is based
+# on testing, and reading the source-code.  For the latter, analysis is aided
+# by the developer's extensive use of hard-coded strings.
+#
+# The website has an example "Tricky unicode", which shows a shell command
+# with a typo (i.e., assuming that a byte in octal uses 4 digits) and suggests
+# that mosh and OS X Terminal "gets it right".
+#
+# The example as shown would not work.  Correcting the typo, xterm gives the
+# result expected by the mosh developer.
+#
+# The other examples follow in a similar vein.
+#
+# It does not support these xterm features:
+#	use=ansi+rep (xterm patch #36, 1997)
+#	use=ecma+strikeout (xterm patch #305, 2014)
+#	use=vt420+lrmm (xterm patch #279, 2012)
+#	titlestack in smcup/rmcup has no effect (xterm patch #251, 2009)
+#	does not support "dim" (xterm patch #305, 2014)
+# In tack
+#	rmkx/smkx has no effect on numeric keypad
+#	acs stuff has no effect, is included here for ease of comparison
+#
+# Unlike screen and tmux, mosh has only limited awareness of a terminal
+# description.  It assumes that the underlying terminal is xterm, and would
+# not work well with terminals using other key-definitions, such as urxvt.

+#
+# + This uses ncurses to manage the display, including support for italics and
+#   default-colors.
+# + However, default-colors are incomplete: do not set bce.
+# + It does not implement flash (since no \e[?5h)
+# + Do not set XT: dvtm knows about OSC 0 and 2, but not 1.
+#   Oddly enough, if $TERM contains "linux", it attempts to set the title.
+# + Some of the program is cut/paste from rxvt-unicode, e.g., the ACS table.
+# + The built-in table of function-keys (based on rxvt) is incomplete (ends
+#   with kf22).
+# + It also omits the shifted cursor- and editing-keypad keys.
+#   However, it is confused by xterm's shifted cursor- and editing-keypad keys
+#   (and passes those through without interpretation)
+#   and may simply pass-through rxvt's, making it appear to work.
+#   In other cases such as kf23 and up, no pass-through is done.
+# + Most of the mode-settings in the initialization/reset strings are not
+#   implemented; dvtm copies its description from rxvt.

+# These entries are for the Embeddable Linux Kernel System (ELKS)
+# project - an heavily stripped down Linux to be run on 16 bit
+# boxes or, eventually, to be used in embedded systems - and have been
+# adapted from the stock ELKS termcap. The project itself looks stalled,
+# and the latest improvements I know of date back to March 2000.
+#
+# To cope with the ELKS dumb console I added an "elks-glasstty" entry;
+# as an added bonus, this deals with all the capabilities common to
+# both VT52 and ANSI (or, eventually, "special") modes.

+#### Microsoft (miscellaneous)
+
+# This entry fits the Windows NT console when the _POSIX_TERM environment
+# variable is set to 'on'.  While the Windows NT POSIX console is seldom used,
+# the Telnet client supplied with both the Windows for WorkGroup 3.11 TCP/IP
+# stack and the Win32 (i.e., Windows 95 and Windows NT 3.1 or later) operating
+# systems is not, and (surprise!) they match very well.
+#
+# See:  MS Knowledge Base item Q108581, dated 13-MAY-1997, titled "Setting Up
+# VI POSIX Editor for Windows NT 3.1".  True to Microsoft form, not only
+# are the installation instructions a pile of mind-numbing bureaucratese,
+# but the termcap entry is actually broken and unusable as given; the :do:
+# capability is misspelled "d".
+#
+# To use this, you need to a bunch of environment variables:
+#
+# SET _POSIX_TERM=on
+# SET TERM=ansi
+# SET TERMCAP=location of termcap file in POSIX file format
+# which is case-sensitive.
+# e.g. SET TERMCAP=//D/RESKIT35/posix/termcap
+# SET TMP=//C/TEMP
+#
+# Important note: setting the TMP environment variable in POSIX style renders
+# it incompatible with a lot of other applications, including Visual C++. So
+# you should have a separate command window just for vi. All the other
+# variables may be permanently set in the Control Panel\System applet.
+#
+# You can find out more about the restrictions of this facility at
+# <https://jeffpar.github.io/kbarchive/kb/108/Q108581/>

+# These guys are long since out of the terminals business, but
+# in 1995 many current terminals still have an adm type as one of their
+# emulations (usually their stupidest, and usually labeled adm3, though
+# these `adm3' emulations normally have adm3a+ capabilities).
+#
+# WARNING: Some early ADM terminals (including the ADM3 and ADM5) had a
+# `diagnostic feature' that sending them a ^G while pin 22 (`Ring Indicator')
+# was being held to ground would trigger a send of the top line on the screen.
+# A quick fix might be to drop back to a cheesy 4-wire cable with pin 22
+# hanging in the air. (Thanks to Eric Fischer, <eric@fudge.uchicago.edu>,

+# You will need to get into the supervisor setup before you can set

+# see a lot more setup options.
+#
+# While in supervisor setup you can also use following codes:
+#
+# Ctrl-P Personality character selections (configure for example what
+#        arrow keys send, if I recall correctly)
+# Ctrl-T tabs 1-80   use left&right to move and up to set and
+# Ctrl-V tabs 81-158 down to clear tab. Shift-Ctrl-M sets right margin at cursor
+# Ctrl-B Binary setup (probably not needed. I think that everything can
+#        be set using normal setup)
+# Ctrl-A Answerback mode (enter answerback message)
+# Ctrl-U User friendly mode (normal setup)
+# Ctrl-D Defaults entire setup and function keys from EPROM tables
+# Ctrl-S Save both setup and functions keys. Takes from 6 to 10 seconds.
+# Ctrl-R Reads both setup and functions keys from NVM.
+# Shift-Ctrl-X Unlock keyboard and cancel received X-OFF status
+#
+# ADM-12+ supports hardware handshaking, but it is DTR/CTS as opposed to
+# RTS/CTS used nowadays with virtually every modem and computer. 19200
+# bps works fine with hardware flow control.
+#
+# The following null-modem cable should fix this and enable you to use
+# RTS/CTS handshaking (which Linux supports, use CRTSCTS setting). Also

+# Qume was bought by Wyse, but still (as of early 1995) has its own support
+# group and production division.
+#
+# Discontinued Qume models:
+#
+# The qvt101 and qvt102 listed here are long obsolete; so is the qvt101+
+# built to replace them, and a qvt119+ which was a 101+ with available wide
+# mode (132 columns).  There was a qvt103 which added VT100/VT131 emulations
+# and an ANSI-compatible qvt203 that replaced it.  Qume started producing
+# ANSI-compatible terminals with the qvt323 and qvt61.
+#
+# Current Qume models (as of February 1995):
+#
+# All current Qume terminals have ANSI-compatible operation modes.
+# Qume is still producing the qvt62, which features emulations for other
+# popular lines such as ADDS, and dual-host capabilities.  The qvt82 is
+# designed for use as a SCO ANSI terminal.  The qvt70 is a color terminal
+# with many emulations including Wyse370, Wyse 325, etc.  Their newest
+# model is the qvt520, which is VT420-compatible.
+#
+# There are some ancient printing Qume terminals under `Daisy Wheel Printers'
+#
+# If you inherit a Qume without docs, try Ctrl-Shift-Setup to enter its
+# setup mode.  Shift-s should be a configuration save to NVRAM.

+# These terminals were produced ca. 1979, and had a 12" monochrome
+# screen, supported 75-9600 baud (no handshaking), monochrome, 7-bit
+# ASCII, and were generally similar to adm3a but with attributes
+# (including some with magic cookies), fancy half-duplex mode, and
+# different bugs.
+#
+# Some operations require truly incredible amounts of padding. The
+# insert_line (<il1>) and delete_line (<dl1>) operations in particular
+# are so slow as to be nearly unusable.
+#
+# There may or may not have been a separate, earlier series of 912/920
+# terminals (without the "B" and "C" suffix); I have never seen one,
+# and the manual only describes the "B" and "C" series. The 912 and 920
+# are quite distinct from the 914 and 924, which were much nicer non-
+# magic-cookie terminals similar to the 950.
+#
+# This is a new description for the following TeleVideo terminals,
+# distinguished chiefly by their keyboards:
+#
+#   TVI-912B - very odd layout, no function keys (84 keys)
+#   TVI-920B - typewriter layout, no function keys (103 keys)
+#   TVI-912C - very odd layout, function keys F1-F11 (82 keys)
+#   TVI-920C - typewriter layout, function keys F1-F11 (101 keys)
+#
+# To choose a setting for the TERM variable, start with the model:
+#
+#    Model  || base name
+# ----------||-----------
+#  TVI-912B || tvi912b
+#  TVI-912C || tvi912c
+#  TVI-920B || tvi920b
+#  TVI-920C || tvi920c
+#
+# Then add a suffix from the following table describing installed options
+# and how you'd like to use the terminal:
+#
+#   Use Video | Second | Visual |  Magic  |  Page || feature
+#  Attributes |  Page  |  Bell  | Cookies | Print || suffix
+# ------------|--------|--------|---------|-------||---------
+#      No     |   No   |  N/A   |   N/A   |   No  || -unk
+#      No     |   No   |  N/A   |   N/A   |  Yes  || -p
+#      No     |  Yes   |   No   |   N/A   |   No  || -2p-unk
+#      No     |  Yes   |   No   |   N/A   |  Yes  || -2p-p
+#      No     |  Yes   |  Yes   |   N/A   |   No  || -vb-unk
+#      No     |  Yes   |  Yes   |   N/A   |  Yes  || -vb-p
+#     Yes     |   No   |  N/A   |    No   |  N/A  ||
+#     Yes     |   No   |  N/A   |   Yes   |  N/A  || -mc
+#     Yes     |  Yes   |   No   |    No   |  N/A  || -2p
+#     Yes     |  Yes   |   No   |   Yes   |  N/A  || -2p-mc
+#     Yes     |  Yes   |  Yes   |    No   |  N/A  || -vb
+#     Yes     |  Yes   |  Yes   |   Yes   |  N/A  || -vb-mc
+#
+# So e.g. a model 920 C with second page memory option, visual bell
+# and no magic cookies would be tvi920c-vb; a model 912 B without the
+# second page memory option and using magic cookies would be
+# tvi912b-mc
+#
+# PADDING
+#
+# At 9600 baud, the terminal is prone to overflow its input buffer
+# during complex operations (insert/delete
+# character/line/screen/page), and it does not signal this over the
+# RS232 cable. The typical symptom of an overrun is that the terminal
+# starts beeping, and output becomes garbled.
+#
+# The padding delays in this terminfo were derived using tack(1)
+# running on a Linux box connected to a TVI-920C with a later-model
+# (A49C1-style) ROM running at 9600 baud, so your mileage may
+# vary. The numbers below seem to give the terminal enough time so
+# that it doesn't overflow its input buffer and start losing
+# characters.
+#
+# KEYS
+#
+# If you want to use the FUNCT key on a tvi912[bc], use the
+# corresponding tvi920[bc] terminfo with FUNCT + ... equivalents from
+# the following table (these also work on the 920 series):
+#
+# Unshifted Function Keys:
+#

+#
+# NON-STANDARD CAPABILITIES
+#
+# Sending <u9> or <u7> returns a cursor position report in the format
+# YX\r, where Y and X are as in <cup>. This format is described in
+# <u8> and <u6>, but it's not clear how one should write an
+# appropriate scanf string, since we need to subtract %' ' from the
+# character after reading it. The <u9> capability is used by tack(1)
+# to synchronize during padding tests, and seems to work for that
+# purpose.
+#
+# This description also includes the obsolete termcap capabilities
+# has_hardware_tabs (<OTpt>) and backspaces_with_bs (<OTbs>).
+#
+# FEATURES NOT YET DESCRIBED IN THIS TERMINFO
+#
+# The FUNCT modifier actually works with every normal key by sending
+# ^AX\r, where X is the sequence normally sent by that key. This is a
+# sort of meta key not currently describable in terminfo.
+#
+# There are quite a few other keys (especially on the 920 models,) but
+# they are for the most part only useful in block mode.
+#
+# These terminals have lots of forms manipulation features, mainly
+# useful in block mode, including "clear X to nulls" (vs. "clear X to
+# spaces"; nulls are sentinels for "send X" operations); "send X"
+# operations for uploading all or part of the screen; and block-mode
+# editing keys (they don't send escape sequences, but manipulate video
+# memory directly). Block mode is used for local editing, and protect
+# mode (in conjunction with the "write protect" attribute,
+# a.k.a. half-intensity outside of protect mode) is used to control
+# which parts of the screen are edited/sent/printed (by <mc0>).
+#
+# There are at least two major families of ROM, "early" and
+# A49B1/A49C1; the major difference seems to be that the latter ROMs
+# support a few extra escape sequences for manipulating the off-screen
+# memory page, and for sending whole pages back to the host (mainly
+# useful in block mode.) The descriptions in this file don't use any
+# of those sequences: set cursor position including page (\E-PYX,
+# where P is \s for page 0 and ! for page 1 [actually only the LSB of
+# P is taken into account, so e.g. 0 and 1 work too,] and Y and X are
+# as in <cup>); read cursor position (\E/), which is analogous to <u9>
+# and returns PYX\r, where P is \s for page 0 or ! for page 1, and YX
+# are as in <cup>, and some "send page" features mainly useful for
+# forms manipulation.
+#
+# The keyboard enable (\E") and disable (\E#) sequences are unused,
+# except that a terminal reset (<is2>) enables the keyboard.
+#
+# Auto-flip mode (\Ev) is likely faster than the scrolling mode (\Ew)
+# enabled in <is2>, but auto-flip is very jarring so we don't use it.
+#
+# BUGS
+#
+# At least up to the A49B1 and A49C1 ROMs, there are no \Eb and \Ed
+# sequences (I infer that in some TeleVideo terminal they may invert
+# and uninvert the display) so the <flash> sequence given here is a
+# cheesy page-flip instead.
+#
+# The back_tab (<cbt>) sequence (\EI) doesn't work according to
+# tack(1), so it is not included in the descriptions below.
+#
+# It's not clear whether auto_left_margin (<bw>) flag should be set
+# for these terminals; tack says yes, so it is set here, but this
+# differs from other descriptions I've seen.
+#
+# Extension print mode (<mc5>) echoes all characters to the printer
+# port [in addition to displaying them] except for the page print mode
+# sequence (<mc4>); this is a slight violation of the terminfo
+# definition for <mc5> but I don't expect it to cause problems.  We
+# reset to page print mode in <rs1> since it may have been enabled
+# accidentally.
+#
+# The descriptions with plus signs (+) are building blocks.

+# Visual 50 from Beau Shekita, BTL-Whippany <whuxlb!ejs>
+# Recently I hacked together the following termcap for Visual
+# Technology's Visual 50 terminal. It's a slight modification of
+# the VT52 termcap.
+# It's intended to run when the Visual 50 is in VT52 emulation mode
+# (I know what you're thinking; if it's emulating a VT52, then why
+# another termcap? Well, it turns out that the Visual 50 can handle
+# <dl1> and db(?) among other things, which the VT52 can't)
+# The termcap works OK for the most part. The only problem is on
+# character inserts. The whole line gets painfully redrawn for each
+# character typed. Any suggestions?
+# Beau's entry is combined with the vi50 entry from University of Wisconsin.
+# Note especially the <il1> function.  <kf4>-<kf6> are really l4-l6 in
+# disguise; <kf7>-<kf9> are really l1-l3.

+# These entries include a few small fixes.

+#	the protect mode to support one attribute (dim) without cookies.
+#	If more than one attribute is needed then the wy30-mc terminfo

+#	The Wyse 350 is a Wyse 50 with color.
+#	Unfortunately this means that it has magic cookies.
+#	The color attributes are designed to overlap the reverse, dim and
+#	underline attributes.  This is nice for monochrome applications
+#	because you can make underline stuff green (or any other color)
+#	but for true color applications it's not so hot because you cannot
+#	mix color with reverse, dim or underline.
+#	    To further complicate things one of the attributes must be
+#	black (either the foreground or the background).  In reverse video
+#	the background changes color with black letters.  In normal video
+#	the foreground changes colors on a black background.
+#	    This terminfo uses some of the more advanced features of curses
+#	to display both color and blink.  In the final analysis I am not
+#	sure that the wy350 runs better with this terminfo than it does
+#	with the wy50 terminfo (with user adjusted colors).
+#
+#	The mandatory pause used by flash does not work with

+# This copes with an apparent firmware bug in the wy85.  He writes:
+# "What I did was change leave the terminal cursor keys set to Normal
+# (instead of application), and change \E[ to \233 for all the keys in
+# terminfo. At one point, I found some reference indicating that this
+# terminal bug (not sending \E[) was acknowledged by Wyse (so it's not just
+# me), but I can't find that and the server under my bookmark to "Wyse
+# Technical" isn't responding.  So there's the question of whether the wy85
+# terminfo should reflect the manufacturer's intended behaviour of the terminal
+# or the actual."

+#TITLE:  TERMINFO ENTRY WY520
+#DATE:   8/5/93
+# The WY520 terminfo is based on the WY285 entry published on the WYSE
+# BBS with the addition of more function keys and special keys.
+#
+#               rs1 -> set personality
+#               rs2 -> set number of columns
+#               rs3 -> set number of lines
+#               is1 -> select the proper font
+#               is2 -> do the initialization
+#               is3 -> If this string is empty then rs3 gets sent.
+#
+#       Wyse 520 emulating a VT420 7 bit mode with default ANSI keyboard
+#       - The BS key is programmed to generate BS in smcup since
+#         is2 doesn't seem to work.
+#       - Remove and shift/Remove: delete a character
+#       - Insert : enter insert mode
+#       - Find   : delete to end of file
+#       - Select : clear a line
+#       - F11, F12, F13: send default sequences (not ESC, BS, LF)
+#       - F14 : Home key
+#       - Bottom status line (host writable line) is used.
+#       - smkx,rmkx are removed because this would put the numeric
+#         keypad in Dec application mode which doesn't seem to work
+#         with SCO applications.

+######## NON-ANSI TERMINAL EMULATIONS
+#
+
+#### Avatar
+#
+# These entries attempt to describe Avatar, a terminal emulation used with
+# MS-DOS bulletin-board systems.  It was designed to give ANSI-like
+# capabilities, but with cheaper (shorter) control sequences.  Messy design,
+# excessively dependent on PC idiosyncrasies, but apparently rather popular
+# in the BBS world.
+#
+# No color support.  Avatar doesn't fit either of the Tektronix or HP color
+# models that terminfo knows about.  An Avatar color attribute is the
+# low 7 bits of the IBM-PC display-memory attribute.  Bletch.
+#
+# I wrote these entries while looking at the Avatar spec.  I don't have
+# the facilities to test them.  Let me know if they work, or don't.
+#
+# Avatar escapes not used by these entries (because maybe you're smarter
+# and more motivated than I am and can figure out how to wrap terminfo
+# around some of them, and because they are weird enough to be funny):

+# Note: Most terminals, especially the 600 family use Reverse Video for
+# standout mode.  DEC also uses reverse video.  The VT100 uses bold in addition
+# Assume we should stay with reverse video for 70..  However, the 605V2 exits
+# standout mode with \E[m (all normal attributes).  The 730 entry simply
+# exits reverse video which would leave other current attributes intact.  It
+# was assumed the 730 entry to be more correct so rmso has changed.  The
+# 605V2 has no sequences to turn individual attributes off, thus its setting
+# and the rmso/smso settings from the 730.
+#
+# Note: For the same reason as above in rmso I changed exit under-score mode
+# to specifically turn off underscore, rather than return to all normal
+# attributes
+#
+# Note: The following pkey_xmit is taken from the 605V2 which contained the
+# capability as pfxl.  It was changed here to pfx since pfxl
+# will only compile successfully with Unix 4.0 tic.  Also note that pfx only
+# allows strings to be parameters and label values must be programmed as
+# constant strings.  Supposedly the pfxl of Version 4.0 allows both labels
+# and strings to be parameters.  The 605V2 pfx entry should be examined later
+# in this regard. For reference the 730 pfxl entry is shown here for comparison

+#### Ann Arbor (aa)
+#
+# Ann Arbor made dream terminals for hackers -- large screen sizes and huge
+# numbers of function keys.  At least some used monitors in portrait mode,
+# allowing up to 76-character screen heights!  They were reachable at:
+#
+#	Ann Arbor Terminals
+#	6175 Jackson Road
+#	Ann Arbor, MI 48103
+#	(313)-663-8000
+#
+# But in 1996 the phone number reaches some kitschy retail shop, and Ann Arbor
+# can't be found on the Web; I fear they're long dead.  R.I.P.
+#
+
+
+# Originally from Mike O'Brien@Rand and Howard Katseff at Bell Labs.
+# Highly modified 6/22 by Mike O'Brien.
+# split out into several for the various screen sizes by dave-yost@rand
+# Modifications made 3/82 by Mark Horton
+# Modified by Tom Quarles at UCB for greater efficiency and more diversity
+# status line moved to top of screen, <flash> removed 5/82
+# Some unknown person at SCO then hacked the init strings to make them more
+# efficient.

+#### Getronics
+#
+# Getronics is a Dutch electronics company that at one time was called
+# `Geveke' and made async terminals; but (according to the company itself!)
+# they've lost all their documentation on the command set.  The hardware
+# documentation suggests the terminals were actually manufactured by a
+# Taiwanese electronics company named Cal-Comp.  There are known
+# to have been at least two models, the 33 and the 50.
+#
+
+# The 50 seems to be a top end VT220 clone, with the addition of a higher
+# screen resolution, a larger screen, at least 1 page of memory above and
+# below the screen, apparently pages of memory right and left of the screen
+# which can be panned, and about 75 function keys (15 function keys x normal,
+# shift, control, func A, func B). It also has more setup possibilities than
+# the VT220. The monitor case is dated November 1978 and the keyboard case is
+# May 1982.
+#
+# The VT100 emulation works as is.  The entry below describes the rather
+# non-conformant (but more featureful) ANSI mode.

+# Some unknown person at SCO then translated it to terminfo.
+#
+# There seem to be a number of different versions of the C108 PROMS
+# (with bug fixes in its Z-80 program).
+#
+# The first one that we had would lock out the keyboard of you
+# sent lots of short lines (like /usr/dict/words) at 9600 baud.
+# Try that on your C108 and see if it sends a ^S when you type it.
+# If so, you have an old version of the PROMs.
+#
+# You should configure the C108 to send ^S/^Q before running this.
+# It is much faster (at 9600 baud) than the c100 because the delays
+# are not fixed.
+# new status line display entries for c108-8p:
+# <is3> - init str #3 - setup term for status display -
+# set programmer mode, select window 2, define window at last
+# line of memory, set bkgnd stat mesg there, select window 0.
+#
+# <tsl> - to status line - select window 2, home cursor, erase to
+# end-of-window, 1/2 bright on, goto(line#0, col#?)
+#
+# <fsl> - from status line - 1/2 bright off, select window 0
+#
+# <dsl> - disable status display - set bkgnd status mesg with
+# illegal window #
+#
+# There are probably more function keys that should be added but
+# I don't know what they are.
+#
+# No delays needed on c108 because of ^S/^Q handshaking

+# These have only window relative cursor addressing, not screen
+# relative. To get it to work right here, smcup/rmcup (which
+# were invented for the concept) lock you into a one page
+# window for screen style programs.
+#
+# To get out of the one page window, we use a clever trick:
+# we set the window size to zero ("\Ev    " in rmcup) which the
+# terminal recognizes as an error and resets the window to all
+# of memory.
+#
+# This trick works on c100 but does not on c108, sigh.
+#
+# Some tty drivers use cr3 for concept, others use nl3, hence
+# the delays on cr and ind below. This padding is only needed at

+# local conventions.
+#
+# 2 ms padding on <rmcup> isn't always enough. 6 works fine. Maybe

+#
+# Note: can't use function keys f7-f10 because they are

+# clear: Could be done with \E[2J alone, except that vi (and probably most

+#	\E[2;029!t to is2.
+# lines: is set to 24 because this terminal refuses to treat the 25th

+# ll:	Not available in power on mode, but turned on with \E[=107;207h in

+# lm:	Pointless, given that this definition locks a single screen of
+#	memory into view, but what the hey...
+# rmso: Could use \E[1;7!{ to turn off only bold and reverse (leaving any
+#	other attributes alone), but some programs expect this to turn off
+#	everything.
+# rmul: Could use \E[4!{ to turn off only underline (leaving any other
+#	attributes alone), but some programs expect this to turn off
+#	everything.
+# sgr:	Attributes are set on this terminal with the string \E[ followed by
+#	a list of attribute code numbers (in decimal, separated by
+#	semicolons), followed by the character m.  The attribute code
+#	numbers are:
+#		  1 for bold;
+#		  2 for dim (which is ignored in power on mode);
+#		  4 for underline;
+#		  5 for blinking;
+#		  7 for inverse;
+#		  8 for not displayable; and
+#		=99 for protected (except that there are strange side
+#		effects to protected characters which make them inadvisable).
+#	 The mapping of terminfo parameters to attributes is as follows:
+#		%p1 (standout) = bold and inverse together;
+#		%p2 (underline) = underline;
+#		%p3 (reverse) = inverse;
+#		%p4 (blink) = blinking;
+#		%p5 (dim) is ignored;
+#		%p6 (bold) = bold;
+#		%p7 (invisible) = not displayable;
+#		%p8 (protected) is ignored; and
+#		%p9 (alt char set) = alt char set.
+#	 The code to do this is:
+#		\E[0		OUTPUT	\E[0
+#		%?%p1%p6%O	IF	(standout; bold) OR
+#		%t;1		THEN	OUTPUT	;1
+#		%;		ENDIF

+#		%?%p9		IF	altcharset
+#		%t^N		THEN	OUTPUT	^N
+#		%e^O		ELSE	OUTPUT	^O
+#		%;		ENDIF
+# sgr0: Everything is turned off (including alternate character set), since
+#	there is no way of knowing what it is that the program wants turned
+#	off.
+# smul: The "underline" attribute is reconfigurable to an overline or
+#	strike-through, or (as done with \E[;3+} in is2=), to a line at the true
+#	bottom of the character cell.  This was done to allow for more readable
+#	underlined characters, and to be able to distinguish between an
+#	underlined space, an underscore, and an underlined underscore.
+# xenl: Terminal can be configured to not need this, but this "glitch"
+#	behavior is actually preferable with autowrap terminals.
+#
+# Parameters kf31= thru kf53= actually contain the strings sent by the shifted
+# Fkeys.  There are no parameters for shifted Fkeys in terminfo.  The is2
+# string modifies the 'O' in kf43 to kf46 to a '$'.
+#

+# set the bell mode also sets the key click volume, and there is no way to say
+# "leave that alone", or to know what it's set to, either.
+# The second way to do a flash is to set the screen to inverse video, pad for a
+# tenth of a second, and set it back - but like before, there's no way to know
+# that the screen wasn't ALREADY in inverse video, or that the user may prefer
+# it that way.  The point is moot anyway, since vi (and probably other

+#### Data General (dg)
+#
+# According to James Carlson <carlson@xylogics.com> writing in January 1995,
+# the terminals group at Data General was shut down in 1991; all these
+# terminals have thus been discontinued.
+#
+# DG terminals have function keys that respond to the SHIFT and CTRL keys,
+# e.g., SHIFT-F1 generates a different code from F1.  To number the keys
+# sequentially, first the unmodified key codes are listed as F1 through F15.
+# Then their SHIFT versions are listed as F16 through F30, their CTRL versions
+# are listed as F31 through F45, and their CTRL-SHIFT versions are listed as
+# F46 through F60.  This is done in the private "includes" below whose names
+# start with "dgkeys+".
+#
+# DG terminals generally support 8 bit characters.  For each of these terminals
+# two descriptions are supplied:
+#	1) A default description for 8 bits/character communications, which
+#	   uses the default DG international character set and keyboard codes.
+#	2) A description with suffix "-7b" for 7 bits/character communications.
+#	   This description must use the NON-DEFAULT native keyboard language.
+
+# Unmodified fkeys (kf1-kf11), Shift fkeys (kf12-kf22), Ctrl fkeys (kf23-kf33),
+# Ctrl/Shift fdkeys (kf34-kf44).

+#### Harris (Beehive)
+#
+# Bletch.  These guys shared the Terminal Brain Damage laurels with Hazeltine.
+# Their terminal group is ancient history now (1995) though the parent
+# company is still in business.
+#
+
+# Beehive documentation is undated and marked Preliminary and has no figures
+# so we must have early Superbee2 (Model 600, according to phone conversation
+# with mfr.). It has proved reliable except for some missing padding
+# (notably after \EK and <nl> at bottom of screen).
+#
+# The key idea is that AEP mode is poison for <cup> & that US's in
+# the local memory should be avoided like the plague. That means
+# that the 2048 character local buffer is used as 25 lines of 80
+# characters, period. No scrolling local memory, folks. It also
+# appears that we cannot use naked INS LINE feature since it uses
+# US. The sbi fakes <il1> with an 80-space insert that may be too
+# slow at low speeds; also spaces get converted to \040 which is
+# too long for some programs (not vi).  DEL LINE is ok but slow.
+#
+# The <nl> string is designed for last line of screen ONLY; cup to
+# 25th line corrects the motion inherent in scrolling to Page 1.
+#
+# There is one understood bug. It is that the screen appears to
+# pop to a new (blank) page after a <nel>, or leave a half-line
+# ellipsis to a quad that is the extra 48 memory locations. The
+# data received is dumped into memory but not displayed.  Not to
+# worry if <cup> is being used; the lines not displayed will be,
+# whenever the cursor is moved up there. Since <cup> is addressed
+# relative to MEMORY of window, nothing is lost; but beware of
+# relative cursor motion (<cuu1>,<cud1>,<cuf1>,<cub1>). Recommended,
+# therefore, is setenv MORE -c .
+#
+# WARNING: Not all features tested.
+#
+# Timings are assembled from 3 sources. Some timings may reflect
+# SB2/Model 300 that were used if more conservative.
+# Tested on a Model 600 at 1200 and 9600 bd.
+#
+# The BACKSPACEkb option is cute. The NEWLINE key, so cleverly
+# placed on the keyboard and useless because of AEP, is made
+# into a backspace key. In use ESC must be pressed twice (to send)
+# and sending ^C must be prefixed by ESC to avoid that weird
+# transmit mode associated with ENTER key.
+#
+# IF TERMINAL EVER GOES CATATONIC with the cursor buzzing across
+# the screen, then it has dropped into ENTER mode; hit
+# RESET--ONLINE--!tset.
+#
+# As delivered this machine has a FATAL feature that will throw
+# it into that strange transmit state (SPOW) if the space bar is
+# hit after a CR is received, but before receiving a LF (or a
+# few others).
+#
+# The circuits MUST be modified to eliminate the SPOW latch.
+# This is done by strapping on chip A46 of the I/O board; cut
+# the p.c. connection to Pin 5 and strap Pin 5 to Pin 8 of that
+# chip. This mod has been checked out on a Mod 600 of Superbee II.
+# With this modification absurdly high timings on cr are
+# unnecessary.
+#
+# NOTE WELL that the rear panel switch should be set to CR/LF,
+# not AEP!

+# Some notes about the abm85h entries:
+# 1) there are several firmware revs of 85H in the world. Use abm85h-old for
+#    firmware revs prior to SP51
+# 2) Make sure to use abm85h entry if the terminal is in 85h mode and the
+#    abm85e entry if it is in tvi920 emulation mode. They are incompatible
+#    in some places and NOT software settable i.e., <is2> can't fix it)
+# 3) In 85h mode, the arrow keys and special functions transmit when
+#    the terminal is in dup-edit, and work only locally in local-edit.
+#    Vi won't swallow `del char' for instance, but <smcup> turns on
+#    dup-edit anyway so that the arrow keys will work right. If the
+#    arrow keys don't work the way you like, change <smcup>, <rmcup>, and
+#    <is2>.  Note that 920E mode does not have software commands to toggle
+#    between dup and local edit, so you get whatever was set last on the
+#    terminal.
+# 4) <flash> attribute is nice, but seems too slow to work correctly
+#    (\Eb<pad>\Ed)
+# 5) Make sure `hidden' attributes are selected. If `embedded' attributes
+#    are selected, the <xmc@> entry should be removed.
+# 6) auto new-line should be on (selectable from setup mode only)

+#### Microdata/MDIS
+#
+# This was a line of terminals made by McDonnell-Douglas Information Systems.
+# These entries come direct from MDIS documentation.  I have edited them only
+# to move primary names of the form p[0-9] * to aliases, and to comment out
+# <rmacs>/<smacs> in a couple of entries without <acsc> strings.  I have
+# also removed the change history; the last version indicates this is
+# version 4.3 by A.Barkus, September 1990 (earliest entry is October 1989).
+#
+
+# McDonnell Information Systems Terminal Family History
+# =========================================
+#
+# Prism-1, Prism-2 and P99:
+#       Ancient Microdata and CMC terminals, vaguely like ADDS Regent 25.
+#
+# Prism-4 and Prism-5:
+#       Slightly less ancient range of Microdata terminals. Follow-on from
+#       Prism-2, but with many enhancements. P5 has eight display pages.
+#
+# Prism-6:
+#       A special terminal for use with library systems, primarily in Germany.
+#       Limited numbers. Similar functionality to P5 (except attributes?).
+#
+# Prism-7, Prism-8 and Prism-9:
+#       More recent range of MDIS terminals, in which P7 and P8
+#       replace the P4 & P5, with added functionality, and P9 is the flagship.
+#       The P9 has two emulation modes - P8 and ANSI - and includes a
+#       large number of the DEC VT220 control sequences. Both
+#       P8 and P9 support 80c/24ln/8pg and 132cl/24li/4pg formats.
+#
+# Prism-12 and Prism-14:
+#       Latest range, functionally very similar to the P9.  The P14 has a
+#       black-on-white overscanning screen.
+#
+# The terminfo definitions given here are:
+#
+# p2      - Prism-2 (or Prism-1 or P99).
+#
+# p4      - Prism-4 (and older P7s & P8s).
+# p5      - Prism-5 (or Prism-6).
+#
+# p7      - Prism-7.
+# p8      - Prism-8 (in national or multinational mode).
+# p8-w    - 132 column version of p8.
+# p9      - Prism-9 in ANSI mode.
+# p9-w    - 132 column version of p9.
+# p9-8    - Prism-9 in Prism-8 emulation mode.
+# p9-8-w  - As p9-8, but with 132 columns.
+#
+# p12     - Prism-12 in ANSI mode.
+# p12-w   - 132 column version of p12.
+# p12-m   - Prism-12 in MDC emulation mode.
+# p12-m-w - As p12-m, but with 132 columns.
+# p14     - Prism-14 in ANSI mode.
+# p14-w   - 132 column version of p14.
+# p14-m   - Prism-14 in MDC emulation mode.
+# p14-m-w - As p14-m, but with 132 columns.
+#
+# p2: Prism-2
+# -----------
+#
+# Includes Prism-1 and basic P99 without SP or MP loaded.
+# The simplest form of Prism-type terminal.
+# Basic cursor movement and clearing operations only.
+# No video attributes.
+# Notes:
+#  Horizontal cursor qualifiers of NUL, XON and XOFF are mapped to the next
+#  value up, followed by backspace.

+# 1 selects ANSI mode
+# 2 selects ANSI edit-mode
+# 3 selects VT52 mode
+#
+# One odd thing about the description (which has been unchanged since the 90s)
+# is that the cursor addressing is using VT52 mode, and a few others use the
+# VT52's non-CSI versions of ANSI, e.g., \EJ.  A possible explanation is that
+# the developer used Emacs, which misuses cvvis (this description sets VT52

+# Coherent, Minix, Venix, and several lesser-known kin were OSs for 8088
+# machines that tried to emulate the UNIX look'n'feel.  Coherent and Venix
+# were commercial, Minix an educational tool sold in conjunction with a book.
+# Memory-segmentation limits and a strong tendency to look like V7 long after
+# it was obsolete made all three pretty lame.  Venix croaked early.  Coherent
+# and Minix were ported to 32-bit Intel boxes, only to be run over by a
+# steamroller named `Linux' (which, to be fair, traces some lineage to Minix).
+# Coherent's vendor, the Mark Williams Company, went belly-up in 1994.  There
+# are also, I'm told, Minix ports that ran on Amiga and Atari machines and
+# even as single processes under SunOS and the Macintosh OS.

+#### Bell Labs blit terminals
+#
+# These were AT&T's official entries.  The 5620 FAQ maintained by
+# David Breneman <daveb@dgtl.com> has this to say:
+#
+#  Actually, in the beginning was the Jerq, and the Jerq was white with a
+#  green face, and Locanthi and Pike looked upon the Jerq and said the Jerq
+#  was good.  But lo, upon the horizon loomed a mighty management-type person
+#  (known now only by the initials VP) who said, the mighty Jerq must stay
+#  alone, and could not go forth into the world. So Locanthi and Pike put the
+#  Jerq to sleep, cloned its parts, and the Blit was brought forth unto the
+#  world. And the Jerq lived the rest of its days in research, but never
+#  strayed from those paths.
+#
+#  In all seriousness, the Blit was originally known as the Jerq, but when
+#  it started to be shown outside of the halls of the Bell Labs Research
+#  organization, the management powers that be decided that the name could
+#  not remain. So it was renamed to be Blit. This was in late 1981.
+#
+# (The AT&T 5620 was the commercialized Blit.  Its successors were the 630,
+# 730, and 730+.)

+# Jeff DelPapa <dp@world.std.com> writes:
+# The bitgraph was a large white box that contained a monochrome bitmap
+# display, and a 68000 to run it.  You could download code and run it on
+# the cpu, it had 128kb (I think) of memory.  I used one in the late
+# 70's, sure beat a VT100.  It had one strange feature tho -- it used
+# the cpu to bitblt pixels to scroll, it took longer than the refresh
+# rate, and looked like a rubber sheet stretching, then snapping
+# upwards.  It had everything the early mac had, except a floppy drive a
+# small screen (it had a 17" crisp beauty) and a real OS. They (Bolt
+# Beranek and Neuman) sold at most a few hundred of them to the real
+# world.  DOD may have bought more...
+#
+
+# Entries for the BitGraph terminals.  The problem
+# with scrolling in vi can only be fixed by getting BBN to put
+# smarter scroll logic in the terminal or changing vi or padding
+# scrolls with about 500 ms delay.
+#
+# I always thought the problem was related to the terminal
+# counting newlines in its input buffer before scrolling and
+# then moving the screen that much. Then vi comes along and
+# paints lines in on the bottom line of the screen, so you get
+# this big white gap.

+#### DEC terminals (Obsolete types: DECwriter and VT40/42/50)

+# These entries came from DEC's official terminfos for its older terminals
+# (which happen to be identical to the AT&T/SCO terminal descriptions),
+# Bill Hedberg <hedberg@hannah.enet.dec.com> of Terminal Support Engineering
+# may have had more information.  Updated terminfos and termcaps were available
+# at ftp://gatekeeper.dec.com/pub/DEC/termcaps.
+
+# DEC's terminfos did not describe the auxiliary keypad.
+#
+# DECScope of course had no "function keys", but this building block assigns
+# the three blank keys at the top of the auxiliary (numeric) keypad, using
+# the same analogy as VT100 (also lacking function-keys).
+#
+# These assignments use the same layout for 0-9 as VT100+keypad; the VT52
+# keypad had its cursor-keys on the right-column as shown -TD

+# Tim tells us that:
+# I have an old Zenith-19 terminal at home that still gets a lot of use.
+# This terminal suffers from the same famous insert-mode padding lossage
+# that has been acknowledged for the Z29 terminal.  Emacs is nearly
+# unusable on this box, since even a half-scroll up or down the window
+# causes flaming terminal death.
+#
+# On the Z19, the only way I have found around this problem is to remove
+# the :al: and :dl: entries entirely.  No amount of extra padding will
+# help (I have tried up to 20000).  Removing <il1=\EL$> and <dl1=\EM$>
+# makes Emacs a little slower, but it remains in the land of the living.
+# Big win.

+# The major problem with the Z29 is that it requires more padding than the Z19.
+#
+# The problem with declaring an H19 to be synonymous with a Z29 is that
+# it needs more padding. It especially loses if a program attempts
+# to put the Z29 into insert mode and insert text at 9600 baud. It
+# even loses worse if the program attempts to insert tabs at 9600
+# baud. Adding padding to text that is inserted loses because in
+# order to make the Z29 not die, one must add so much padding that
+# whenever the program tries to use insert mode, the effective
+# rate is about 110 baud.
+#
+# What program would want to put the terminal into insert mode
+# and shove stuff at it at 9600 baud you ask?
+#
+# Emacs. Emacs seems to want to do the mathematically optimal
+# thing in doing a redisplay rather than the practical thing.
+# When it is about to output a line on top of a line that is
+# already on the screen, instead of just killing to the end of
+# the line and outputting the new line, it compares the old line
+# and the new line and if there are any similarities, it
+# constructs the new line by deleting the text on the old line
+# on the terminal that is already there and then inserting new
+# text into the line to transform it into the new line that is
+# to be displayed. The Z29 does not react kindly to this.
+#
+# But don't cry for too long.... There is a solution. You can make
+# a termcap entry for the Z29 that says the Z29 has no insert mode.
+# Then Emacs cannot use it. "Oh, no, but now inserting into a
+# line will be really slow", you say. Well there is a sort of a
+# solution to that too. There is an insert character option on
+# the Z29 that will insert one character. Unfortunately, it
+# involves putting the terminal into ANSI mode, inserting the
+# character, and changing it back to H19 mode. All this takes 12
+# characters. Pretty expensive to insert one character, but it
+# works. Either Emacs doesn't try to use its inserting hack when
+# it's only given an insert character ability or the Z29 doesn't
+# require padding with this (the former is probably more likely,
+# but I haven't checked it out).

+# Bob Manson <manson@pattyr.acs.ohio-state.edu> writes (28 Apr 1995):
+#
+# Synertek used to make ICs, various 6502-based single-board process
+# control and hobbyist computers, and assorted peripherals including a
+# series of small inexpensive terminals (I think they were one of the
+# first to have a "terminal-on-a-keyboard", where the terminal itself
+# was only slightly larger than the keyboard).
+#
+# They apparently had a KTM-1 model, which I've never seen. The KTM-2/40
+# was a 40x24 terminal that could connect to a standard TV through a
+# video modulator.  The KTM-2/80 was the 80-column version (the 2/40
+# could be upgraded to the 2/80 by adding 2 2114 SRAMs and a new ROM).
+# I have a KTM-2/80 still in working order.  The KTM-2s had fully
+# socketed parts, used 2 6507s, a 6532 as keyboard scanner, a program
+# ROM and 2 ROMs as character generators. They were incredibly simple,
+# and I've never had any problems with mine (witness the fact that mine
+# was made in 1981 and is still working great... I've blown the video
+# output transistor a couple of times, but it's a 2N2222 :-)
+#
+# The KTM-3 (which is what is listed in the terminfo file) was their
+# attempt at putting a KTM-2 in a box (and some models came with a
+# CRT). It wasn't much different from the KTM-2 hardware-wise, but the
+# control and escape sequences are very different. The KTM-3 was always
+# real broken, at least according to the folks I've talked to about it.
+#
+# The padding in the entry is probably off--these terminals were very
+# slow (it takes like 100ms for the KTM-2 to clear the screen...) And
+# anyone with any sanity replaced the ROMs with something that provided
+# a reasonable subset of VT100 functionality, since the usual ROMs were
+# obviously very primitive... oh, you could get an upgraded ROM from
+# Synertek for some incredible amount of money, but what hacker with an
+# EPROM burner would do that? :)
+#
+# Sorry I don't have any contact info; I believe they were located in
+# Sunnyvale, and I'm fairly sure they are still manufacturing ICs
+# (they've gone to ASICs and FPGAs), but I doubt they're in the computer

+# From: Benjamin C. W. Sittler <bsittler@nmt.edu>
+#
+# I have a UNIX PC which I use as a terminal attached to my Linux PC.
+# Unfortunately, the UNIX PC terminfo entry that comes with ncurses
+# is broken. All the special key sequences are broken, making it unusable
+# with Emacs. The problem stems from the following:
+#
+# The UNIX PC has a plethora of keys (103 of them, and there's no numeric
+# keypad!), loadable fonts, and strange highlighting modes ("dithered"
+# half-intensity, "smeared" bold, and real strike-out, for example.) It also
+# uses resizable terminal windows, but the bundled terminal program always
+# uses an 80x24 window (and doesn't support seem to support a 132-column
+# mode.)
+#
+# HISTORY: The UNIX PC was one of the first machines with a GUI, and used a
+# library which was a superset of SVr3.5 curses (called tam, for "terminal
+# access method".) tam includes support for real, overlapping windows,
+# onscreen function key labels, and bitmap graphics. But since the primary
+# user interface on the UNIX PC was a GUI program (ua, for "user
+# assistant",) and remote administration was considered important for the
+# machine, tam also supported VT100-compatible terminals attached to the
+# serial port or used across the StarLan network. To simulate the extra keys
+# not present on a VT100, users could press ESC and a two-letter sequence,
+# such as u d (Undo) or U D (Shift-Undo.) These two-letter sequences,
+# however, were not the same as those sent by the actual Undo key. The
+# actual Undo key sends ESC 0 s unshifted, and ESC 0 S shifted, for example.
+# (If you're interested in adding some of the tam calls to ncurses, btw, I
+# have the full documentation and several programs which use tam. It also
+# used an extended terminfo format to describe key sequences, special
+# highlighting modes, etc.)
+#
+# KEYS: This means that ncurses would quite painful on the UNIX PC, since
+# there are two sequences for every key-modifier combination (local keyboard
+# sequence and remote "VT100" sequence.) But I doubt many people are trying
+# to use ncurses on the UNIX PC, since ncurses doesn't properly handle the
+# GUI. Unfortunately, the terminfo entry (and the termcap, too, I presume)
+# seem to have been built from the manual describing the VT100 sequences.
+# This means it doesn't work for a real live UNIX PC.
+#
+# FONTS: The UNIX PC also has a strange interpretation of "alternate
+# character set". Rather than the VT100 graphics you might expect, it allows
+# up to 8 custom fonts to be loaded at any given time. This means that
+# programs expecting VT100 graphics will usually be disappointed. For this
+# reason I have disabled the smacs/rmacs sequences, but they could easily be
+# re-enabled. Here are the relevant control sequences (from the ESCAPE(7)
+# manpage), should you wish to do so:
+#
+# SGR10 - Select font 0 - ESC [ 10 m or SO
+# SGR11 - Select font 1 - ESC [ 11 m or SI
+# SGR12 - Select font 2 - ESC [ 12 m
+# ... (etc.)
+# SGR17 - Select font 7 - ESC [ 17 m
+#
+# Graphics for line drawing are not reliably found at *any* character
+# location because the UNIX PC has dynamically reloadable fonts. I use font
+# 0 for regular text and font 1 for italics, but this is by no means
+# universal. So ASCII line drawing is in order if smacs/rmacs are enabled.
+#
+# MISC: The cursor visible/cursor invisible sequences were swapped in the
+# distributed terminfo.
+#
+# To ameliorate these problems (and fix a few highlighting bugs) I rewrote
+# the UNIX PC terminfo entry. The modified version works great with Lynx,
+# Emacs, and XEmacs running on my Linux PC and displaying on the UNIX PC
+# attached by serial cable. In Emacs, even the Undo key works, and many
+# applications can now use the F1-F8 keys.

+# 1. underlining is not allowed with colors: first, is is simulated by
+# black on white, second, it disables background color manipulations.
+# 2. BLINKING, REVERSE and BOLD are allowed with colors,
+# so we have to save their status in the static registers A, B and H
+# respectively, to be able to restore them when color changes
+# (because any color change turns off ALL attributes)
+# 3. <bold> and <rev> sequences alternate modes,
+# rather than simply  entering them.  Thus we have to check the
+# static register B and H to determine the status, before sending the
+# escape sequence.
+# 4. <sgr0> now must set the status of all 3 register (A,B,H) to zero
+# and then reset colors
+# 5. implementation of the protect mode would badly penalize the performance.
+# we would have to use \E&bn sequence to turn off colors (as well as all
+# other attributes), and keep the status of protect mode in yet another
+# static variable.  If someone really needs this mode, they would have to
+# create another terminfo entry.
+# 6. original color-pair is white on black.

+#   1) turn off all attributes
+#   2) turn on the background and video attributes that have been turned
+#      on before (this information is stored in static registers X,Y,Z,A,B,H,D).
+#   3) turn on foreground attributes

+# was a like the VT-240 (monochrome with Regis + Sixel graphics), and the 3222
+# was like the VT-241 (color with Regis + Sixel Graphics).  These terminals
+# (3221) cost about $1500 each, and one was always broken -- had to be sent
+# back to the shop for repairs.
+# The only real advantage these scopes had over the VT-240's were:
+# 1) They were faster in the Regis display, or at least the ones I did
+# 2) They had a handy debugging feature where you could split-screen the
+# scope, the graphics would appear on the top, and the REGIS commands would
+# appear on the bottom.  I don't remember the VT-240s being able to do that.
+# I would swear that LANPAR Technologies was in MA someplace, but since I
+# don't work at the same place anymore, and those terminals and manuals were
+# long since junked, I cannot be any more sure than that.
+#
+# (v3220: removed obsolete ":kn#10:",
+# I added <rmam>/<smam> based on the init string -- esr)

+######## ICH/ICH1 VERSUS RMIR/SMIR
+#
+# Some non-curses applications get confused if both ich/ich1 and rmir/smir
+# are present; the symptom is doubled characters in an update using insert.
+# These applications are technically correct; in both 4.3BSD termcap and
+# terminfo, you're not actually supposed to specify both ich/ich1 and rmir/smir
+# unless the terminal needs both.  To my knowledge, no terminal still in this
+# file requires both other than the very obsolete dm2500.
+#
+# For ncurses-based applications this is not a problem, as ncurses uses
+# one or the other as appropriate but never mixes the two.  Therefore we
+# have not corrected entries like `linux' and `xterm' that specify both.
+# If you see doubled characters from these, use the linux-nic and xterm-nic
+# entries that suppress ich/ich1.  And upgrade to ncurses!

+######## VT100/ANSI/ISO 6429/ECMA-48/PC-TERM TERMINAL STANDARDS
+#
+# ANSI X3.64 has been withdrawn and replaced by ECMA-48.  The ISO 6429 and
+# ECMA-48 standards are said to be almost identical, but are not the same
+# as X3.64 (though for practical purposes they are close supersets of it).
+#
+# You can obtain ECMA-48 for free by sending email to helpdesk@ecma.ch
+# requesting the standard(s) you want (i.e. ECMA-48, "Control Functions for
+# Coded Character Sets"), include your snail-mail address, and you should
+# receive the document in due course.  Don't expect an email acknowledgment.
+#
+# Related standards include "X3.4-1977: American National Standard Code for
+# Information Interchange" (the ASCII standard) and "X3.41.1974:
+# Code-Extension Techniques for Use with the 7-Bit Coded Character Set of
+# American National Standard for Information Interchange."  I believe (but
+# am not certain) that these are effectively identical to ECMA-6 and ECMA-35
+# respectively.

+#
+# Much of the content of this comment is adapted from a table prepared by
+# Richard Shuford, based on a 1984 Byte article.  Terminfo correspondences,
+# discussion of some terminfo-related issues, and updates to capture ECMA-48
+# have been added.  Control functions described in ECMA-48 only are tagged
+# with * after their names.
+#
+# The table is a complete list of the defined ANSI X3.64/ECMA-48 control
+# sequences.  In the main table, \E stands for an escape (\033) character,
+# SPC for space.  Pn stands for a single numeric parameter to be inserted
+# in decimal ASCII.  Ps stands for a list of such parameters separated by
+# semicolons.  Parameter meanings for most parameterized sequences are
+# described in the notes.

+# Notes:
+#
+# Some control characters are listed in the ECMA-48 standard without
+# being assigned functions relevant to terminal control there (they
+# referred to other standards such as ISO 1745 or ECMA-35).  They are listed
+# here anyway for completeness.
+#
+# (A) ECMA-48 calls this "CancelCharacter" but retains the CCH abbreviation.
+#
+# (B) There seems to be some confusion abroad between CHA and HPA.  Most
+# `ANSI' terminals accept the CHA sequence, not the HPA. but terminfo calls
+# the capability (hpa).  ECMA-48 calls this "Cursor Character Absolute" but
+# preserved the CHA abbreviation.
+#
+# (C) CHT corresponds to terminfo (tab).  Usually it has the value ^I.
+# Occasionally (as on, for example, certain HP terminals) this has the HTJ
+# value.  ECMA-48 calls this "Cursor Forward Tabulation" but preserved the
+# CHT abbreviation.
+#
+# (D) terminfo (nel) is usually \r\n rather than ANSI \EE.
+#
+# (E) ECMA-48 calls this "Active Position Report" but preserves the CPR

+#
+# (G) CUP and HVP are identical in effect.  Some ANSI.SYS versions accept
+# HVP, but always allow CUP as an alternate.  ECMA-48 calls HVP "Character
+# Position Absolute" but retains the HVP abbreviation.
+#
+# (H) ECMA calls this "Cursor Line Tabulation" but preserves the CVT

+#	3 = malfunction,
+#	4 = malfunction, will send DSR later,
+#	5 = request DSR,

+# (J) ECMA calls ED "Erase In Page". EA/ED/EL parameters:
+#	0 = clear to end,
+#	1 = clear from beginning,
+#	2 = clear.
+#
+# (K) ECMA calls this "End of Guarded Area" but preserves the EPA abbreviation.
+#
+# (L) The GSM parameters are vertical and horizontal parameters to scale by.
+#
+# (M) Some ANSI.SYS versions accept HPR, but more commonly `ANSI' terminals

+#
+# Ce     is a control represented as a single bit combination in the C1 set
+#        of controls in an 8-bit character set
+#
+# C0     the familiar set of 7-bit ASCII control characters
+#
+# C1     roughly, the set of control chars available only in 8-bit systems.
+#        This is too complicated to explain fully here, so read Jim Fleming's
+#        article in the February 1983 BYTE, especially pages 214 through 224.
+#
+# Fe     is a Final character of a 2-character Escape sequence that has an
+#        equivalent representation in an 8-bit environment as a Ce-type
+#        (Fe ranges from 4/0 to 5/15)
+#
+# Fs     is a Final character of a 2-character Escape sequence that is

+#        and 8-bit environments and is independent of the currently
+#        designated C0 and C1 control sets (Fs ranges from 6/0 to 7/14)
+#
+# I      is an Intermediate character from 2/0 to 2/15 (inclusive) in the

+#
+# Ps     is a variable number of selective parameters in a control sequence
+#        with each selective parameter separated from the other by the code
+#        3/11 (which usually represents a semicolon); Ps ranges from
+#        3/0 to 3/9 and includes 3/11
+#
+# *      Not relevant to terminal control, listed for completeness only.
+#
+# Format Effectors versus Editor Functions
+#
+# A format effector specifies how following output is to be displayed.
+# An editor function allows you to modify the display.  Informally
+# format effectors may be destructive; format effectors should not be.
+#
+# For instance, a format effector that moves the "active position" (the
+# cursor or equivalent) one space to the left would be useful when you want to
+# create an overstrike, a compound character made of two standard characters
+# overlaid. Control-H, the Backspace character, is actually supposed to be a
+# format effector, so you can do this. But many systems use it in a
+# nonstandard fashion, as an editor function, deleting the character to the
+# left of the cursor and moving the cursor left. When Control-H is assumed to
+# be an editor function, you cannot predict whether its use will create an
+# overstrike unless you also know whether the output device is in an "insert
+# mode" or an "overwrite mode". When Control-H is used as a format effector,
+# its effect can always be predicted. The familiar characters carriage
+# return, linefeed, formfeed, etc., are defined as format effectors.
+#
+# NOTES ON THE DEC VT100 IMPLEMENTATION
+#
+# Control sequences implemented in the VT100 are as follows:
+#
+#      CPR, CUB, CUD, CUF, CUP, CUU, DA, DSR, ED, EL, HTS, HVP, IND,
+#      LNM, NEL, RI, RIS, RM, SGR, SM, TBC
+#
+# plus several private DEC commands.
+#
+# Erasing parts of the display (EL and ED) in the VT100 is performed thus:
+#
+#      Erase from cursor to end of line           Esc [ 0 K    or Esc [ K
+#      Erase from beginning of line to cursor     Esc [ 1 K
+#      Erase line containing cursor               Esc [ 2 K
+#      Erase from cursor to end of screen         Esc [ 0 J    or Esc [ J
+#      Erase from beginning of screen to cursor   Esc [ 1 J
+#      Erase entire screen                        Esc [ 2 J
+#
+# Some brain-damaged terminal/emulators respond to Esc [ J as if it were
+# Esc [ 2 J, but this is wrong; the default is 0.
+#
+# The VT100 responds to receiving the DA (Device Attributes) control
+#
+#      Esc [ c    (or Esc [ 0 c)
+#
+# by transmitting the sequence
+#
+#      Esc [ ? l ; Ps c
+#
+# where Ps is a character that describes installed options.
+#
+# The VT100's cursor location can be read with the DSR (Device Status
+# Report) control
+#
+#      Esc [ 6 n
+#
+# The VT100 reports by transmitting the CPR sequence
+#
+#      Esc [ Pl ; Pc R
+#
+# where Pl is the line number and Pc is the column number (in decimal).
+#
+# The specification for the DEC VT100 is document EK-VT100-UG-003.
+
+#### ANSI.SYS
+#
+# Here is a description of the color and attribute controls supported in the
+# the ANSI.SYS driver under MS-DOS.  Most console drivers and ANSI
+# terminal emulators for Intel boxes obey these.  They are a proper subset
+# of the ECMA-48 escapes.
+#
+# 0	all attributes off
+# 1	foreground bright
+# 4	underscore on
+# 5	blink on/background bright (not reliable with brown)
+# 7	reverse-video
+# 8	set blank (non-display)
+# 10	set primary font
+# 11	set first alternate font (on PCs, display ROM characters 1-31)
+# 12	set second alternate font (on PCs, display IBM high-half chars)
+#
+#			Color attribute sets
+# 3n	set foreground color       / 0=black, 1=red,     2=green, 3=brown,
+# 4n	set background color       \ 4=blue,  5=magenta, 6=cyan,  7=white
+# Bright black becomes gray.  Bright brown becomes yellow,
+# These coincide with the prescriptions of the ISO 6429/ECMA-48 standard.
+#
+# * If the 5 attribute is on and you set a background color (40-47) it is
+#   supposed to enable bright background.
+#
+# * Many VGA cards (such as the Paradise and compatibles) do the wrong thing
+#   when you try to set a "bright brown" (yellow) background with attribute
+#   5 (you get a blinking yellow foreground instead).  A few displays
+#   (including the System V console) support an attribute 6 that undoes this
+#   braindamage (this is required by iBCS2).
+#
+# * Some older versions of ANSI.SYS have a bug that causes them to require
+#   ESC [ Pn k as EL rather than the ANSI ESC [ Pn K.  (This is not ECMA-48
+#   compatible.)
+
+#### Intel Binary Compatibility Standard
+#
+# For comparison, here are the capabilities implied by the Intel Binary
+# Compatibility Standard for UNIX systems (Intel order number 468366-001).
+# These recommendations are optional.  IBCS2 allows the leading escape to
+# be either the 7-bit \E[ or 8-bit \0233 introducer, in accordance with
+# the ANSI X.364/ISO 6429/ECMA-48 standard.  Here are the iBCS2 capabilities
+# (as described in figure 9-3 of the standard).  Those expressed in the ibcs2
+# terminfo entry are followed with the corresponding capability in parens:
+#
+#	CSI <n>k		disable (n=0) or enable (n=1) keyclick
+#	CSI 2h			lock keyboard
+#	CSI 2i			send screen as input
+#	CSI 2l			unlock keyboard

+#	CSI =<p>;<d>B		set bell parameters
+#	CSI =<s>;<e>C		set cursor parameters
+#	CSI =<x>D		enable/disable intensity of background color

+#	CSI H		(hts)	(hts) set tab stop
+#	CSI Q<n><string>	define function key string
+#				(string must begin and end with delimiter char)
+#	CSI c		(clear) clear screen
+#
+# The lack of any specification for attributes in SGR (among other things)
+# makes this a wretchedly weak standard. The table above is literally
+# everything iBSC2 has to say about terminal escape sequences; there is
+# no further discussion of their meaning or how to set the parameters
+# in these sequences at all.

+#	GR	Gr	right-tick character       |-
+#	GC	Gc	middle intersection   -|-
+#	GU	Gu	up-tick character          _|_
+#
+# These were invented to take advantage of the IBM PC ROM character set.  One
+# can compose an acsc string from the single-width characters as follows
+#	"j{G4}k{G1}l{G2}m{G3}q{GH}x{GV}t{GR}u{GL}v{GU}w{GD}n{GC}"
+# When translating a termcap file, ncurses tic will do this automatically.
+# The double forms characters don't fit the SVr4 terminfo model.
+#
+#### AT&T Extensions:
+#
+# The old AT&T 5410, 5420, 5425, pc6300plus, 610, and s4 entries used a set of
+# nonstandard capabilities.  Its signature is the KM capability, used to name
+# some sort of keymap file.  EE, BO, CI, CV, XS, DS, FL and FE are in this
+# set.  Comments in the original, and a little cross-checking with other AT&T
+# documentation, seem to establish that BO=:mr: (start reverse video), DS=:mh:
+# (start dim), XS=:mk: (secure/invisible mode), EE=:me: (end highlights),
+# FL=:LO: (enable soft labels), FE=:LF: (disable soft labels), CI=:vi: (make
+# cursor invisible), and CV=:ve: (make cursor normal).
+#
+#### HP Extensions
+#
+# The HP library (as of mid-1995, their term.h file version 70.1) appears to
+# have the System V capabilities up to SVr1 level.  After that, it supports
+# two nonstandard caps meml and memu corresponding to the old termcap :ml:,
+# :mu: capabilities.  After that, it supports caps plab_norm, label_on,
+# label_off, and key_f11..key_f63 capabilities like SVr4's.  This makes the
+# HP binary format incompatible with SVr4's.
+#
+#### IBM Extensions
+#
+# There is a set of nonstandard terminfos used by IBM's AIX operating system.
+# The AIX terminfo library diverged from SVr1 terminfo, and replaces all
+# capabilities following prtr_non with the following special capabilities:
+# box[12], batt[12], colb[0123456789], colf[0123456789], f[01234567], kbtab,
+# kdo, kcmd, kcpn, kend, khlp, knl, knpn, kppn, kppn, kquit, ksel, kscl, kscr,
+# ktab, kmpf[123456789], apstr, ksf1..ksf10, kf11...kf63, kact, topl, btml,
+# rvert, lvert.   Some of these are identical to XPG4/SVr4 equivalents:
+# kcmd, kend, khlp, and kf11...kf63.  Two others (kbtab and ksel) can be
+# renamed (to kcbt and kslt).  The places in the box[12] capabilities
+# correspond to acsc chars, here is the mapping:
+#
+#	box1[0]  = ACS_ULCORNER
+#	box1[1]  = ACS_HLINE
+#	box1[2]  = ACS_URCORNER
+#	box1[3]  = ACS_VLINE
+#	box1[4]  = ACS_LRCORNER
+#	box1[5]  = ACS_LLCORNER
+#	box1[6]  = ACS_TTEE
+#	box1[7]  = ACS_RTEE
+#	box1[8]  = ACS_BTEE
+#	box1[9]  = ACS_LTEE
+#	box1[10] = ACS_PLUS
+#
+# The box2 characters are the double-line versions of these forms graphics.
+# The AIX binary terminfo format is incompatible with SVr4's.
+#
+#### Iris console extensions:
+#
+# HS is half-intensity start; HE is half-intensity end
+# CT is color terminal type (for Curses & rogue)
+# CP is color change escape sequence
+# CZ are color names (for Curses & rogue)
+#
+# The ncurses tic utility recognizes HS as an alias for mh <dim>.
+#
+#### TC Extensions:
+#
+# There is a set of extended termcaps associated with something
+# called the "Terminal Control" or TC package created by MainStream Systems,
+# Winfield Kansas.  This one also uses GS/GE for as/ae, and also uses
+# CF for civis and CO for cvvis.  Finally, they define a boolean :ct:
+# that flags color terminals.
+#
+######## NCURSES USER-DEFINABLE CAPABILITIES
+#
+# Extensions added after ncurses 5.0 generally use the "-x" option of tic and
+# infocmp to manipulate user-definable capabilities.  Those that are intended
+# for use in either terminfo or termcap use 2-character names.  Extended
+# function keys do not use 2-character names, and are available only with
+# terminfo.
+#
+# Beginning in 2010, NetBSD curses has also provided a "-x" option for
+# tic/infocmp, and uses this database (with a few changes).  There are a few
+# differences, noted in
+#	https://invisible-island.net/ncurses/ncurses-netbsd.html
+#
+# ncurses makes explicit checks for a few user-definable capabilities:  AX,
+# RGB, U8, XM, which are documented in the user_caps(5) manual page.
+#
+#### SCREEN Extensions:
+#
+# The screen program uses the termcap interface.  It recognizes a few useful
+# nonstandard capabilities.  Those are used in this file.
+#
+#       AX   (bool)  Does  understand  ANSI  set  default fg/bg color (\E[39m /
+#                    \E[49m).
+#       G0   (bool)  Terminal can deal with ISO 2022  font  selection sequences.
+#       E0   (str)   Switch charset 'G0' back to standard charset.
+#       S0   (str)   Switch charset 'G0' to the specified charset.
+#       XT   (bool)  Terminal understands special xterm sequences  (OSC,  mouse
+#                    tracking).
+#
+# AX is relatively straightforward; it is interpreted by ncurses to say that
+# SGR 39/49 reset the terminal's foreground and background colors to their
+# "default".
+#
+# XT is harder, since screen's manpage does not give more details.  For that,
+# we must read screen's source-code.  For example, when XT is set, screen
+# assumes
+#
+# a) OSC 1 sets the title string, e.g., for the icon.  Recent versions of
+#    screen may also set the terminal's name, which is (for xterm) distinct
+#    from the icon name.
+# b) OSC 20 sets the background pixmap.  This is an rxvt feature.
+# c) OSC 39 and OSC 49 set the default foreground/background colors.  Again
+#    this is an rxvt feature.
+# d) certain mode settings enable the mouse: 9, 1000, 1001, 1002, 1003.
+#    These are from xterm, although xterm accepts mouse codes that may not be
+#    recognized by screen, e.g., 1005, 1006.
+# e) colors beyond 0..7 are implemented by xterm's aixterm-like 16-color
+#    sequence.  However, because screen uses only termcap, the values returned
+#    by Af/Ab are not usable because they rely on expressions that termcap
+#    does not support.  Therefore, screen uses a hardcoded string to work
+#    around the limitation.  In a few cases, screen also uses tparm, which
+#    is a terminfo function rather than termcap.
+# f) all entries named "*xterm*" or "*rxvt*" have the bce flag set.
+# g) screen also uses the feature to decide whether to pay attention to other
+#    xterm-related features which are unrelated to the description in the
+#    manual page.
+#
+# Since XT is useful only when the outer terminal matches screen's assumptions,
+# it is appropriate to use it in the derived terminal descriptions such as
+# "screen.xterm", but not in the generic "screen", "screen-bce" entries.
+#
+# The other ISO-2022 features are rarely used, but provided here to make
+# screen's termcap features available.
+#
+#### XTERM Extensions:
+#
+# For a discussion of "xterm", "xterm-256color" as values for TERM, see
+#	https://invisible-island.net/ncurses/ncurses.faq.html#xterm_generic
+#	https://invisible-island.net/ncurses/ncurses.faq.html#xterm_256color
+#
+# For xterm control sequences, see
+#	https://invisible-island.net/xterm/ctlseqs/ctlseqs.html
+#
+# For function-keys with modifiers, see
+#	https://invisible-island.net/ncurses/ncurses.faq.html#modified_keys
+#
+# For a discussion of "bracketed paste", see
+#	https://invisible-island.net/xterm/xterm-paste64.html
+#
+# Most of the xterm extensions are for function-keys.  Since xterm patch #94 (in
+# 1999), xterm has supported shift/control/alt/meta modifiers which produce
+# additional function-key strings.  Some other developers copied the feature,
+# though they did not follow xterm's lead in xterm patch #167 (in 2002), to make
+# these key definitions less ambiguous.
+#
+# A few terminals provide similar functionality (sending distinct keys when
+# a modifier is used), including rxvt.
+#
+# These are the extended keys defined in this file:
+#
+# kDC3 kDC4 kDC5 kDC6 kDC7 kDN kDN3 kDN4 kDN5 kDN6 kDN7 kEND3 kEND4 kEND5 kEND6
+# kEND7 kHOM3 kHOM4 kHOM5 kHOM6 kHOM7 kIC3 kIC4 kIC5 kIC6 kIC7 kLFT3 kLFT4
+# kLFT5 kLFT6 kLFT7 kNXT3 kNXT4 kNXT5 kNXT6 kNXT7 kPRV3 kPRV4 kPRV5 kPRV6 kPRV7
+# kRIT3 kRIT4 kRIT5 kRIT6 kRIT7 kUP kUP3 kUP4 kUP5 kUP6 kUP7 ka2 kb1 kb3 kc2
+#
+# Bracketed paste is described with these capabilities in vim:
+#
+# BE enables bracketed paste
+# BD disables bracketed paste
+# PS is sent before the pasted text
+# PE is sent after the pasted text
+#
+# Here are the other xterm-related extensions which are used in this file:
+#
+# Cr is a string capability which resets the cursor color
+# Cs is a string capability which sets the cursor color to a given value.
+#    The single string parameter is the color name/number, according to the
+#    implementation.
+# Ms modifies the selection/clipboard.  Its parameters are
+#	p1 = the storage unit (clipboard, selection or cut buffer)
+#	p2 = the base64-encoded clipboard content.
+# Se resets the cursor style to the terminal power-on default.
+# Ss is a string capability with one numeric parameter.  It is used to set the
+#    cursor style as described by the DECSCUSR function to a block or
+#    underline.
+# TS is a string capability which acts like "tsl", but uses no parameter and
+#    goes to the first column of the "status line".
+# XM is a string capability which overrides ncurses's built-in string which
+#    enables/disables xterm mouse mode.
+# xm shows the format of the mouse responses.  Parameters:
+#	p1 = y-ordinate
+#	p2 = x-ordinate
+#	p3 = button
+#	p4 = state, e.g., pressed or released
+#	p5 = y-ordinate starting region
+#	p6 = x-ordinate starting region
+#	p7 = y-ordinate ending region
+#	p8 = x-ordinate ending region
+# Other extensions, used in xm:
+#	%u = UTF-8
+#
+#### Miscellaneous extensions:
+#
+# csr clears the status line
+# gsbom/grbom are used to enable/disable real bold (not intensity bright) mode.
+#    This was implemented for the Hurd.
+# rmxx/smxx describes the ECMA-48 strikeout/crossed-out attributes, as an
+#    experimental feature of tmux.
+# CO gives the number of indexed ("ANSI") colors which overlay an RGB color
+#    space.
+# E3 clears the terminal's scrollback buffer.  This was implemented in the
+#    Linux 3.0 kernel as a security feature.  It matches a feature which was
+#    added in xterm patch #107.
+# NQ denotes a terminal which does not support the standard query/response used
+#    in u6/u7 (cursor position) and u8/u9 (device attributes).
+# U8 is a numeric capability which denotes a terminal emulator which does not
+#    support VT100 SI/SO when processing UTF-8 encoding.  Set this to a nonzero
+#    value to enable it.
+# Smulx modifies the appearance of underlines in VTE, December 2017.
+#
+######## CHANGE HISTORY
+#
+# The last /etc/termcap version maintained by John Kunze was 8.3, dated 8/5/94.
+# Releases 9 and 10 (up until the release of ncurses 4.2 in 1998) were
+# maintained by Eric S. Raymond as part of the ncurses project.
+#
+# This file contains all the capability information present in John Kunze's
+# last version of the termcap master file, except as noted in the change
+# comments at end of file.  Some information about very ancient obsolete
+# capabilities has been moved to comments.  Some all-numeric names of older
+# terminals have been retired.
+#
+# I changed :MT: to :km: (the 4.4BSD name) everywhere.  I commented out some
+# capabilities (EP, dF, dT, dV, kn, ma, ml, mu, xr, xx) that are no longer
+# used by BSD curses.
+#
+# The 9.1.0 version of this file was translated from my lightly-edited copy of
+# 8.3, then mechanically checked against 8.3 using Emacs Lisp code written for
+# the purpose.  Unless the ncurses tic implementation and the Lisp code were
+# making perfectly synchronized mistakes which I then failed to catch by
+# eyeball, the translation was correct and perfectly information-preserving.
+#
+# Major version number bumps correspond to major version changes in ncurses.
+#
+# Here is a log of the changes since then:
+#
+# 9.1.0 (Wed Feb  1 04:50:32 EST 1995):

+#	* Added the new BSDI pc3 entry.
+# 9.5.2 (Tue Apr 25 17:27:52 EDT 1995)
+#	* A change in the tic -C logic now ensures that all entries in
+#	  the termcap translation will fit in < 1024 bytes.
+#	* Added `bobcat' and `gator' HP consoles and the Nu machine entries
+#	  from GNU termcap file.  This merges in all their local information.
+# 9.5.3 (Tue Apr 25 22:28:13 EDT 1995)
+#	* Changed tic -C logic to dump all capabilities used by GNU termcap.
+#	* Added warnings about entries with long translations (restoring
+#	  all the GNU termcaps pushes a few over the edge).
+# 9.5.4 (Wed Apr 26 15:35:09 EDT 1995)
+#	* Yet another tic change, and a couple of entry tweaks, to reduce the
+#	  number of long (> 1024) termcap translations back to 0.

+#	  when ich1/ich is present (copes with an ancient vi bug).
+#	* Added `screen' entries from FSF's screen-3.6.2.
+#	* Added linux-nic and xterm-nic entries.
+# 9.6.2 (Sat May  6 17:00:55 EDT 1995):
+#	* Change linux entry to use smacs=\E[11m and have an explicit acsc,
+#	  eliminating some special-case code in ncurses.
+#
+# 9.7.0 (Tue May  9 18:03:12 EDT 1995):
+#	* Added vt320-k3, rsvidtx from the Emacs termcap.dat file.  I think
+#	  that captures everything unique from it.
+#	* Added reorder script generator.
+#	* Freeze for ncurses 1.9.2 release.
+# 9.7.1 (Thu Jun 29 09:35:22 EDT 1995):
+#	* Added Sean Farley's kspd, flash, rs1 capabilities for linux.
+#	* Added Olaf Siebert's corrections for adm12.
+#	* ansi-pc-color now includes the colors and pairs caps, so that
+#	  entries which use it will inherit them automatically.
+#	* The linux entry can now recognize the center (keypad 5) key.
+#	* Removed some junk that found its way into Linux acsc.
+#
+# 9.8.0 (Fri Jul  7 04:46:57 EDT 1995):
+#	* Add 50% cut mark as a desperate hack to reduce tic's core usage.
+#	* xterm doesn't try to use application keypad mode any more.
+#	* Freeze for ncurses-1.9.3 release.
+# 9.8.1 (Thu Jul 19 17:02:12 EDT 1995):
+#	* Added corrected sun entry from vendor.
+#	* Added csr capability to linux entry.
+#	* Peter Wemm says the at386 hpa should be \E[%i%p1%dG, not \E[%p1%dG.
+#	* Added vt102-nsgr to cope with stupid IBM PC `VT100' emulators.
+#	* Some commented-out caps in long entries come back in, my code
+#	  for computing string-table lengths had a bug in it.
+#	* pcansi series modified to fit comm-program reality better.
+# 9.8.2 (Sat Sep  9 23:35:00 EDT 1995):
+#	* BSD/OS actually ships the ibmpc3 bold entry as its console.
+#	* Correct some bad aliases in the pcansi series
+#	* Added entry for QNX console.
+#	* Clean up duplicate long names for use with 4.4 library.
+#	* Change vt100 standout to be normal reverse vide, not bright reverse;
+#	  this makes the Emacs status line look better.
+# 9.8.3 (Sun Sep 10 13:07:34 EDT 1995):
+#	* Added Adam Thompson's VT320 entries, also his dtx-sas and z340.
+#	* Minor surgery, mostly on name strings, to shorten termcap version.
+#
+# 9.9.0 (Sat Sep 16 23:03:48 EDT 1995):
+#	* Added dec-vt100 for use with the EWAN emulator.
+#	* Added kmous to xterm for use with xterm's mouse-tracking facility.
+#	* Freeze for 1.9.5 alpha release.
+# 9.9.1 (Wed Sep 20 13:46:09 EDT 1995):
+#	* Changed xterm lines to 24, the X11R6 default.
+# 9.9.2 (Sat Sep 23 21:29:21 EDT 1995):

+The llib-lXXXX files could be used as lint-library sources (and were, at one
+time).  However, they are actually used as a documentation aid to keep track
+of changes to the public/private interfaces in ncurses.  Most of the text in
+these files is generated using cproto; some manual cleanup and adjustment of
+types (to reflect #define's in curses.h) is needed.  The functions listed in
+the llib-lXXXX files do not correspond to the default configure options; some
+additional ones are added to include "all" of the entrypoints for each of the
+major configurations (normal, wide-character, threaded):
+

+	--disable-root-environ
+	--enable-expanded
+	--enable-getcap

+
+Here is the patch.  I did no testing whatsoever with event watching
+requests present (I need some applications which exercise this before
+this, probably lynx ;-), but the code looks working "the normal way".
+
+I had no way to test that the poll() branch compiles/works...
+
+Here is the API:
+
+*) two new functions wgetch_events() wgetstrn_event() are introduced,
+   which allow an event-watch specification given as the last argument;
+
+*) if the last argument is NULL, they behave as wgetch() and
+   wgetstrn() (TESTED!);
+
+*) the event specification is a pointer to _nc_eventlist, which
+   contains bookkeeping elements (count and the summary of results),
+   and an array of pointers to _nc_event;
+
+*) each _nc_event is a typed union, with two types supported "as
+   shipped": _NC_EVENT_TIMEOUT_MSEC, _NC_EVENT_FILE.  For
+   _NC_EVENT_FILE the fields are fd, flag, and the output field.
+
+*) The only supported flag "as shipped" is _NC_EVENT_FILE_READABLE.
+   If the file was found readable, the return field is set to this,
+   otherwise to 0;
+
+*) If these functions return KEY_EVENT, this means that the return
+   fields in both the _nc_eventlist and _nc_event structures make
+   sense.  The field result_flags of _nc_eventlist may have a
+   combination of bits _NC_EVENT_TIMEOUT_MSEC and _NC_EVENT_FILE_READABLE
+   set;
+
+*) The timeout_msec field of _NC_EVENT_TIMEOUT_MSEC _nc_event's is
+   updated on return, even if the return is not KEY_EVENT.  However,
+   the change in the value represents only the amount of time spent in
+   waiting for events, not the amount of time spent bookkeeping;
+
+*) the return KEY_EVENT of wgetstrn_event() means that the output
+   string includes the user input typed so far, but the user did not have
+   a chance to press ENTER (or whatever).  This call should be
+   repeated (with "shifted" pointer to a buffer, of course) to
+   complete the input;
+
+*) The presence of this extension can be checked via inspecting
+   #ifdef NCURSES_EVENT_VERSION.  This symbol is not defined on BeOS,
+   since there is no support for this on BeOS.
+
+Known issues:  calls interrupted by KEY_EVENT reset the ESCDELAY
+timer.  This is not entirely new, since other synthetic events behave
+the same (see "if (ch >= KEY_MIN)" branch of kgetch()).  However,
+KEY_EVENT may be generated in a continuous stream (say, when
+downloading a file), thus this may be more important than with other
+synthetic keys.  An additional field in window structure which keeps
+timestamp of the first raw key in the queue may be needed to
+circumvent this.
+
+Another possible issue: KEY_EVENT has a preference over a user input,
+so a stream of KEY_EVENT's can make input hard.  Maybe use
+result_flags as in input parameter too, which specifies whether the
+user input should have higher precedence?
+
+Also: I took an opportunity to document kgetch() better.
+
+Enjoy,
+Ilya

+# The XSI Curses standard requires all curses entry points to exist as
+# functions, even though many definitions would normally be shadowed
+# by macros.  Rather than hand-hack all that code, we actually
+# generate functions from the macros.
+#
+# This script accepts a file of prototypes on standard input.  It discards
+# any that don't have a `generated' comment attached. It then parses each
+# prototype (relying on the fact that none of the macros take function
+# pointer or array arguments) and generates C source from it.
+#
+# Here is what the pipeline stages are doing:
+#
+# 1. sed: extract prototypes of generated functions
+# 2. sed: decorate prototypes with generated arguments a1. a2,...z
+# 3. awk: generate the calls with args matching the formals
+# 4. sed: prefix function names in prototypes so the preprocessor won't expand
+#         them.
+# 5. cpp: macro-expand the file so the macro calls turn into C calls
+# 6. awk: strip the expansion junk off the front and add the new header
+# 7. sed: squeeze spaces, strip off gen_ prefix.
+#
+
+# keep the editing independent of locale:

+/*
+ * This module is intended to encapsulate ncurses's interface to pointing
+ * devices.
+ *
+ * The primary method used is xterm's internal mouse-tracking facility.
+ * Additional methods depend on the platform:
+ *	Alessandro Rubini's GPM server (Linux)
+ *	sysmouse (FreeBSD)
+ *	special-purpose mouse interface for OS/2 EMX.
+ *
+ * Notes for implementors of new mouse-interface methods:
+ *
+ * The code is logically split into a lower level that accepts event reports
+ * in a device-dependent format and an upper level that parses mouse gestures
+ * and filters events.  The mediating data structure is a circular queue of
+ * MEVENT structures.
+ *
+ * Functionally, the lower level's job is to pick up primitive events and
+ * put them on the circular queue.  This can happen in one of two ways:
+ * either (a) _nc_mouse_event() detects a series of incoming mouse reports
+ * and queues them, or (b) code in lib_getch.c detects the kmous prefix in
+ * the keyboard input stream and calls _nc_mouse_inline to queue up a series
+ * of adjacent mouse reports.
+ *
+ * In either case, _nc_mouse_parse() should be called after the series is
+ * accepted to parse the digested mouse reports (low-level MEVENTs) into
+ * a gesture (a high-level or composite MEVENT).
+ *
+ * Don't be too shy about adding new event types or modifiers, if you can find
+ * room for them in the 32-bit mask.  The API is written so that users get
+ * feedback on which theoretical event types they won't see when they call
+ * mousemask. There's one bit per button (the RESERVED_EVENT bit) not being
+ * used yet, and a couple of bits open at the high end.

+The files in this directory (tinfo) are those that support the terminfo
+database and interfaces for ncurses.  The terminfo library can be built
+separately, as a lower-level library for ncurses, but usually is bundled.
+
+In addition to the standard documented interfaces, ncurses uses internal
+functions which reside in tinfo to satisfy linkage requirements.

+ *	captoinfo.c
+ *
+ *	Provide conversion in both directions between termcap and terminfo.
+ *
+ * cap-to-info --- conversion between termcap and terminfo formats
+ *
+ *	The captoinfo() code was swiped from Ross Ridge's mytinfo package,
+ *	adapted to fit ncurses by Eric S. Raymond <esr@snark.thyrsus.com>.
+ *
+ *	It has just one entry point:
+ *
+ *	char *_nc_captoinfo(n, s, parameterized)
+ *
+ *	Convert value s for termcap string capability named n into terminfo
+ *	format.
+ *
+ *	This code recognizes all the standard 4.4BSD %-escapes:
+ *
+ *	%%       output `%'
+ *	%d       output value as in printf %d
+ *	%2       output value as in printf %2d
+ *	%3       output value as in printf %3d
+ *	%.       output value as in printf %c
+ *	%+x      add x to value, then do %.
+ *	%>xy     if value > x then add y, no output
+ *	%r       reverse order of two parameters, no output
+ *	%i       increment by one, no output
+ *	%n       exclusive-or all parameters with 0140 (Datamedia 2500)
+ *	%B       BCD (16*(value/10)) + (value%10), no output
+ *	%D       Reverse coding (value - 2*(value%16)), no output (Delta Data).
+ *
+ *	Also, %02 and %03 are accepted as synonyms for %2 and %3.
+ *
+ *	Besides all the standard termcap escapes, this translator understands
+ *	the following extended escapes:
+ *
+ *	used by GNU Emacs termcap libraries
+ *		%a[+*-/=][cp]x	GNU arithmetic.
+ *		%m		xor the first two parameters by 0177
+ *		%b		backup to previous parameter
+ *		%f		skip this parameter
+ *
+ *	used by the University of Waterloo (MFCF) termcap libraries
+ *		%-x	 subtract parameter FROM char x and output it as a char
+ *		%ax	 add the character x to parameter
+ *
+ *	If #define WATERLOO is on, also enable these translations:
+ *
+ *		%sx	 subtract parameter FROM the character x
+ *
+ *	By default, this Waterloo translations are not compiled in, because
+ *	the Waterloo %s conflicts with the way terminfo uses %s in strings for
+ *	function programming.
+ *
+ *	Note the two definitions of %a: the GNU definition is translated if the
+ *	characters after the 'a' are valid for it, otherwise the UW definition
+ *	is translated.

+ *	char *
+ *	tparm(string, ...)
+ *
+ *	Substitute the given parameters into the given string by the following
+ *	rules (taken from terminfo(5)):
+ *
+ *	     Cursor addressing and other strings  requiring  parame-
+ *	ters in the terminal are described by a parameterized string
+ *	capability, with escapes like %x in  it.   For  example,  to
+ *	address  the  cursor, the cup capability is given, using two
+ *	parameters: the row and column to  address  to.   (Rows  and
+ *	columns  are  numbered  from  zero and refer to the physical
+ *	screen visible to the user, not to any  unseen  memory.)  If
+ *	the terminal has memory relative cursor addressing, that can
+ *	be indicated by
+ *
+ *	     The parameter mechanism uses  a  stack  and  special  %
+ *	codes  to manipulate it.  Typically a sequence will push one
+ *	of the parameters onto the stack and then print it  in  some
+ *	format.  Often more complex operations are necessary.
+ *
+ *	     The % encodings have the following meanings:
+ *
+ *	     %%        outputs `%'
+ *	     %c        print pop() like %c in printf()
+ *	     %s        print pop() like %s in printf()
+ *           %[[:]flags][width[.precision]][doxXs]
+ *                     as in printf, flags are [-+#] and space
+ *                     The ':' is used to avoid making %+ or %-
+ *                     patterns (see below).
+ *
+ *	     %p[1-9]   push ith parm
+ *	     %P[a-z]   set dynamic variable [a-z] to pop()
+ *	     %g[a-z]   get dynamic variable [a-z] and push it
+ *	     %P[A-Z]   set static variable [A-Z] to pop()
+ *	     %g[A-Z]   get static variable [A-Z] and push it
+ *	     %l        push strlen(pop)
+ *	     %'c'      push char constant c
+ *	     %{nn}     push integer constant nn
+ *
+ *	     %+ %- %* %/ %m
+ *	               arithmetic (%m is mod): push(pop() op pop())
+ *	     %& %| %^  bit operations: push(pop() op pop())
+ *	     %= %> %<  logical operations: push(pop() op pop())
+ *	     %A %O     logical and & or operations for conditionals
+ *	     %! %~     unary operations push(op pop())
+ *	     %i        add 1 to first two parms (for ANSI terminals)
+ *
+ *	     %? expr %t thenpart %e elsepart %;
+ *	               if-then-else, %e elsepart is optional.
+ *	               else-if's are possible ala Algol 68:
+ *	               %? c1 %t b1 %e c2 %t b2 %e c3 %t b3 %e c4 %t b4 %e b5 %;
+ *
+ *	For those of the above operators which are binary and not commutative,
+ *	the stack works in the usual way, with
+ *			%gx %gy %m
+ *	resulting in x mod y, not the reverse.

+ * Termcap compatibility support
+ *
+ * If your OS integrator didn't install a terminfo database, you can call
+ * _nc_read_termcap_entry() to support reading and translating capabilities
+ * from the system termcap file.  This is a kludge; it will bulk up and slow
+ * down every program that uses ncurses, and translated termcap entries cannot
+ * use full terminfo capabilities.  Don't use it unless you absolutely have to;
+ * instead, get your system people to run tic(1) from root on the terminfo
+ * master included with ncurses to translate it into a terminfo database.
+ *
+ * If USE_GETCAP is enabled, we use what is effectively a copy of the 4.4BSD
+ * getcap code to fetch entries.  There are disadvantages to this; mainly that
+ * getcap(3) does its own resolution, meaning that entries read in in this way
+ * can't reference the terminfo tree.  The only thing it buys is faster startup
+ * time, getcap(3) is much faster than our tic parser.

+NAME
+   hardscroll.c -- hardware-scrolling optimization for ncurses
+
+SYNOPSIS
+   void _nc_scroll_optimize(void)
+
+DESCRIPTION
+			OVERVIEW
+
+This algorithm for computes optimum hardware scrolling to transform an
+old screen (curscr) into a new screen (newscr) via vertical line moves.
+
+Because the screen has a `grain' (there are insert/delete/scroll line
+operations but no insert/delete/scroll column operations), it is efficient
+break the update algorithm into two pieces: a first stage that does only line
+moves, optimizing the end product of user-invoked insertions, deletions, and
+scrolls; and a second phase (corresponding to the present doupdate code in
+ncurses) that does only line transformations.
+
+The common case we want hardware scrolling for is to handle line insertions
+and deletions in screen-oriented text-editors.  This two-stage approach will
+accomplish that at a low computation and code-size cost.
+
+			LINE-MOVE COMPUTATION
+
+Now, to a discussion of the line-move computation.
+
+For expository purposes, consider the screen lines to be represented by
+integers 0..23 (with the understanding that the value of 23 may vary).
+Let a new line introduced by insertion, scrolling, or at the bottom of
+the screen following a line delete be given the index -1.
+
+Assume that the real screen starts with lines 0..23.  Now, we have
+the following possible line-oriented operations on the screen:
+
+Insertion: inserts a line at a given screen row, forcing all lines below
+to scroll forward.  The last screen line is lost.  For example, an insertion
+at line 5 would produce: 0..4 -1 5..23.
+
+Deletion: deletes a line at a given screen row, forcing all lines below
+to scroll forward.  The last screen line is made new.  For example, a deletion
+at line 7 would produce: 0..6 8..23 -1.
+
+Scroll up: move a range of lines up 1.  The bottom line of the range
+becomes new.  For example, scrolling up the region from 9 to 14 will
+produce 0..8 10..14 -1 15..23.
+
+Scroll down: move a range of lines down 1.  The top line of the range
+becomes new.  For example, scrolling down the region from 12 to 16 will produce
+0..11 -1 12..15 17..23.
+
+Now, an obvious property of all these operations is that they preserve the
+order of old lines, though not their position in the sequence.
+
+The key trick of this algorithm is that the original line indices described
+above are actually maintained as _line[].oldindex fields in the window
+structure, and stick to each line through scroll and insert/delete operations.
+
+Thus, it is possible at update time to look at the oldnum fields and compute
+an optimal set of il/dl/scroll operations that will take the real screen
+lines to the virtual screen lines.  Once these vertical moves have been done,
+we can hand off to the second stage of the update algorithm, which does line
+transformations.
+
+Note that the move computation does not need to have the full generality
+of a diff algorithm (which it superficially resembles) because lines cannot
+be moved out of order.
+
+			THE ALGORITHM
+
+The scrolling is done in two passes. The first pass is from top to bottom
+scroling hunks UP. The second one is from bottom to top scrolling hunks DOWN.
+Obviously enough, no lines to be scrolled will be destroyed. (lav)
+
+HOW TO TEST THIS:
+
+Use the following production:
+
+hardscroll: hardscroll.c
+	$(CC) -g -DSCROLLDEBUG hardscroll.c -o hardscroll
+
+Then just type scramble vectors and watch.  The following test loads are
+a representative sample of cases:

+NAME
+   hashmap.c -- fill in scramble vector based on text hashes
+
+SYNOPSIS
+   void _nc_hash_map(void)
+
+DESCRIPTION:
+   This code attempts to recognize pairs of old and new lines in the physical
+and virtual screens.  When a line pair is recognized, the old line index is
+placed in the oldindex member of the virtual screen line, to be used by the
+vertical-motion optimizer portion of the update logic (see hardscroll.c).
+
+   Line pairs are recognized by applying a modified Heckel's algorithm,
+sped up by hashing.  If a line hash is unique in both screens, those
+lines must be a pair. Then if the lines just before or after the pair
+are the same or similar, they are a pair too.
+
+   We don't worry about false pairs produced by hash collisions, on the
+assumption that such cases are rare and will only make the latter stages
+of update less efficient, not introduce errors.
+
+HOW TO TEST THIS:
+
+Use the following production:
+
+hashmap: hashmap.c
+	$(CC) -g -DHASHDEBUG hashmap.c hardscroll.c ../objects/lib_trace.o -o hashmap

+**		int mvcur(int old_y, int old_x, int new_y, int new_x)

+**
+** Comparisons with older movement optimizers:
+**    SVr3 curses mvcur() can't use cursor_to_ll or auto_left_margin.
+**    4.4BSD curses can't use cuu/cud/cuf/cub/hpa/vpa/tab/cbt for local
+** motions.  It doesn't use tactics based on auto_left_margin.  Weirdly
+** enough, it doesn't use its own hardware-scrolling routine to scroll up
+** destination lines for out-of-bounds addresses!
+**    old ncurses optimizer: less accurate cost computations (in fact,
+** it was broken and had to be commented out!).

+** Compile with -DMAIN to build an interactive tester/timer for the movement
+** optimizer.  You can use it to investigate the optimizer's behavior.
+** You can also use it for tuning the formulas used to determine whether
+** or not full optimization is attempted.
+**
+** This code has a nasty tendency to find bugs in terminfo entries, because it
+** exercises the non-cup movement capabilities heavily.  If you think you've
+** found a bug, try deleting subsets of the following capabilities (arranged
+** in decreasing order of suspiciousness): it, tab, cbt, hpa, vpa, cuu, cud,
+** cuf, cub, cuu1, cud1, cuf1, cub1.  It may be that one or more are wrong.
+**
+** Note: you should expect this code to look like a resource hog in a profile.
+** That's because it does a lot of I/O, through the tputs() calls.  The I/O
+** cost swamps the computation overhead (and as machines get faster, this
+** will become even more true).  Comments in the test exerciser at the end
+** go into detail about tuning and how you can gauge the optimizer's

+ * Note: This code is fragile!  Its problem is that different OSs
+ * handle restart of system calls interrupted by signals differently.
+ * The ncurses code needs signal-call restart to happen -- otherwise,
+ * interrupted wgetch() calls will return FAIL, probably making the
+ * application think the input stream has ended and it should
+ * terminate.  In particular, you know you have this problem if, when
+ * you suspend an ncurses-using lynx with ^Z and resume, it dies
+ * immediately.
+ *
+ * Default behavior of POSIX sigaction(2) is not to restart
+ * interrupted system calls, but Linux's sigaction does it anyway (at
+ * least, on and after the 1.1.47 I (esr) use).  Thus this code works
+ * OK under Linux.  The 4.4BSD sigaction(2) supports a (non-portable)
+ * SA_RESTART flag that forces the right behavior.  Thus, this code
+ * should work OK under BSD/OS, NetBSD, and FreeBSD (let us know if it
+ * does not).
+ *
+ * Stock System Vs (and anything else using a strict-POSIX
+ * sigaction(2) without SA_RESTART) may have a problem.  Possible
+ * solutions:
+ *
+ *    sigvec      restarts by default (SV_INTERRUPT flag to not restart)
+ *    signal      restarts by default in SVr4 (assuming you link with -lucb)
+ *                and BSD, but not SVr3.
+ *    sigset      restarts, but is only available under SVr4/Solaris.
+ *
+ * The signal(3) call is mandated by the ANSI standard, and its
+ * interaction with sigaction(2) is described in the POSIX standard
+ * (3.3.4.2, page 72,line 934).  According to section 8.1, page 191,
+ * however, signal(3) itself is not required by POSIX.1.  And POSIX is
+ * silent on whether it is required to restart signals.
+ *
+ * So.  The present situation is, we use sigaction(2) with no
+ * guarantee of restart anywhere but on Linux and BSD.  We could
+ * switch to signal(3) and collar Linux, BSD, and SVr4.  Any way
+ * we slice it, System V UNIXes older than SVr4 will probably lose
+ * (this may include XENIX).
+ *
+ * This implementation will probably be changed to use signal(3) in
+ * the future.  If nothing else, it is simpler...

+ * happen, or on the first line of region to scroll down.
+ *
+ * This code makes one aesthetic decision in the opposite way from
+ * BSD curses.  BSD curses preferred pairs of il/dl operations
+ * over scrolls, allegedly because il/dl looked faster.  We, on
+ * the other hand, prefer scrolls because (a) they're just as fast
+ * on many terminals and (b) using them avoids bouncing an
+ * unchanged bottom section of the screen up and down, which is
+ * visually nasty.
+ *
+ * (lav): added more cases, used dl/il when bot==maxy and in csr case.
+ *
+ * I used assumption that capabilities il/il1/dl/dl1 work inside
+ * changed scroll region not shifting screen contents outside of it.

+ * This is an implementation of wcwidth() and wcswidth() (defined in
+ * IEEE Std 1002.1-2001) for Unicode.
+ *
+ * http://www.opengroup.org/onlinepubs/007904975/functions/wcwidth.html
+ * http://www.opengroup.org/onlinepubs/007904975/functions/wcswidth.html
+ *
+ * In fixed-width output devices, Latin characters all occupy a single
+ * "cell" position of equal width, whereas ideographic CJK characters
+ * occupy two such cells. Interoperability between terminal-line
+ * applications and (teletype-style) character terminals using the
+ * UTF-8 encoding requires agreement on which character should advance
+ * the cursor by how many cell positions. No established formal
+ * standards exist at present on which Unicode character shall occupy
+ * how many cell positions on character terminals. These routines are
+ * a first attempt of defining such behavior based on simple rules
+ * applied to data provided by the Unicode Consortium.
+ *
+ * For some graphical characters, the Unicode standard explicitly
+ * defines a character-cell width via the definition of the East Asian
+ * FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes.
+ * In all these cases, there is no ambiguity about which width a
+ * terminal shall use. For characters in the East Asian Ambiguous (A)
+ * class, the width choice depends purely on a preference of backward
+ * compatibility with either historic CJK or Western practice.
+ * Choosing single-width for these characters is easy to justify as
+ * the appropriate long-term solution, as the CJK practice of
+ * displaying these characters as double-width comes from historic
+ * implementation simplicity (8-bit encoded characters were displayed
+ * single-width and 16-bit ones double-width, even for Greek,
+ * Cyrillic, etc.) and not any typographic considerations.
+ *
+ * Much less clear is the choice of width for the Not East Asian
+ * (Neutral) class. Existing practice does not dictate a width for any
+ * of these characters. It would nevertheless make sense
+ * typographically to allocate two character cells to characters such
+ * as for instance EM SPACE or VOLUME INTEGRAL, which cannot be
+ * represented adequately with a single-width glyph. The following
+ * routines at present merely assign a single-cell width to all
+ * neutral characters, in the interest of simplicity. This is not
+ * entirely satisfactory and should be reconsidered before
+ * establishing a formal standard in this area. At the moment, the
+ * decision which Not East Asian (Neutral) characters should be
+ * represented by double-width glyphs cannot yet be answered by
+ * applying a simple rule from the Unicode database content. Setting
+ * up a proper standard for the behavior of UTF-8 character terminals
+ * will require a careful analysis not only of each Unicode character,
+ * but also of each presentation form, something the author of these
+ * routines has avoided to do so far.

+     * So.  This hook *immediately* writes out the referenced entry if it
+     * has no use capabilities.  The compiler main loop refrains from
+     * adding the entry to the in-core list when this hook fires.  If some
+     * other entry later needs to reference an entry that got written
+     * immediately, that's OK; the resolution code will fetch it off disk
+     * when it can't find it in core.

+     * Name collisions will still be detected, just not as cleanly.  The
+     * write_entry() code complains before overwriting an entry that
+     * postdates the time of tic's first call to write_entry().  Thus
+     * it will complain about overwriting entries newly made during the
+     * tic run, but not about overwriting ones that predate it.
+     *
+     * The reason this is a hook, and not in line with the rest of the
+     * compiler code, is that the support for termcap fallback cannot assume
+     * it has anywhere to spool out these entries!

+The programs in this directory are used to test and demonstrate ncurses.
+Some are interesting in themselves, while others merely show how some of
+the library calls are used.  Some date back to the initial releases of
+ncurses during the mid-1990s, such as:
+
+	blue       - Blue Moon, a nifty solitaire (uses color)
+	bs.c       - the game of Battleships (uses color)
+	firework.c - multi-colored fireworks (uses color)
+	gdc.c      - Great Digital Clock (uses color)
+	hanoi.c    - the game of hanoi (uses color essentially)
+	knight.c   - the game of Knight's Tour (uses color)
+	lrtest.c   - test of access to the lower-right corner
+	ncurses.c  - multi-test program (uses color)
+	newdemo.c  - another test from PDCurses (uses color)
+	rain.c     - rain drops keep falling on my head...
+	tclock.c   - analog/digital clock
+	testcurs.c - a test from the PDCurses people (uses color)
+	tracemunch - Perl script to make trace scripts easier to read
+	worm.c     - worms run all over your screen (uses color)
+	xmas.c     - Xmas greeting card
+
+Besides being built as part of ncurses, the programs are also packaged as
+"ncurses-examples".  Despite the name, the programs have been adjusted to
+allow them to build with other curses implementations, to provide a way to
+compare those with ncurses.
+
+You can build the programs by
+
+	./configure
+	make
+
+The configure script has several options which allow you to tell it more
+about the curses implementation for which you are building the examples.
+Use
+
+	./configure --help
+
+to list the options.
+

+
+These programs provide examples of use, but do not comprise a complete set of
+tests.  Here is a list of library externals, noting those that are used:

+dnl -----------------
+dnl The X11R4-X11R6 Xt specification uses an ambiguous String type for most
+dnl character-strings.
+dnl
+dnl It is ambiguous because the specification accommodated the pre-ANSI
+dnl compilers bundled by more than one vendor in lieu of providing a standard C
+dnl compiler other than by costly add-ons.  Because of this, the specification
+dnl did not take into account the use of const for telling the compiler that
+dnl string literals would be in readonly memory.
+dnl
+dnl As a workaround, one could (starting with X11R5) define XTSTRINGDEFINES, to
+dnl let the compiler decide how to represent Xt's strings which were #define'd.
+dnl That does not solve the problem of using the block of Xt's strings which
+dnl are compiled into the library (and is less efficient than one might want).
+dnl
+dnl Xt specification 7 introduces the _CONST_X_STRING symbol which is used both
+dnl when compiling the library and compiling using the library, to tell the
+dnl compiler that String is const.

+dnl -------------
+dnl Check if the make-program handles a ".PHONY" target, e.g,. a target which
+dnl acts as a placeholder.
+dnl
+dnl The ".PHONY" feature was proposed in 2011 here
+dnl     https://www.austingroupbugs.net/view.php?id=523
+dnl and is scheduled for release in P1003.1 Issue 8 (late 2022).
+dnl
+dnl This is not supported by SVr4 make (or SunOS 4, 4.3SD, etc), but works with
+dnl a few others (i.e., GNU make and the non-POSIX "BSD" make):
+dnl
+dnl + This is a GNU make feature (since April 1988, but in turn from binutils,
+dnl   date unspecified).
+dnl
+dnl + It was adopted in NetBSD make in June 1995.
+dnl
+dnl + The other BSD make programs are derived from the NetBSD make (and for
+dnl   that reason are not actually different "implementations").
+dnl
+dnl + Some features of NetBSD make were actually adapted from pmake, which
+dnl   began as a modified GNU make starting in 1993.
+dnl
+dnl + Version 3.8 of the dmake program in January 1992 also implemented this
+dnl   GNU make extension, but is less well known than the BSD make.

+.SH NAME
+bs \- battleships game
+.SH SYNOPSIS
+battle [ -b | -s ] [ -c ]
+.SH DESCRIPTION
+This program allows you to play the familiar Battleships game against the
+computer on a 10x10 board. The interface is visual and largely
+self-explanatory; you place your ships and pick your shots by moving the
+cursor around the `sea' with the rogue/hack motion keys hjklyubn.
+.PP
+Note that when selecting a ship to place, you must type the capital letter
+(these are, after all, capital ships). During ship placement, the `r' command
+may be used to ignore the current position and randomly place your currently
+selected ship. The `R' command will place all remaining ships randomly. The ^L
+command (form feed, ASCII 12) will force a screen redraw).
+.PP
+The command-line arguments control game modes.
+
+.nf
+	-b selects a `blitz' variant
+	-s selects a `salvo' variant
+	-c permits ships to be placed adjacently
+.fi
+
+The `blitz' variant allows a side to shoot for as long as it continues to
+score hits.
+.PP
+The `salvo' game allows a player one shot per turn for each of his/her ships
+still afloat.  This puts a premium scoring hits early and knocking out some
+ships and also makes much harder the situation where you face a superior force
+with only your PT-boat.
+.PP
+Normally, ships must be separated by at least one square of open water. The
+-c option disables this check and allows them to close-pack.
+.PP
+The algorithm the computer uses once it has found a ship to sink is provably
+optimal. The dispersion criterion for the random-fire algorithm may not be.
+.SH AUTHORS
+Originally written by one Bruce Holloway in 1986. Salvo mode added by Chuck A.
+DeGaul (cbosgd!cad). Visual user interface, `closepack' option, code rewrite
+and manual page by Eric S. Raymond <esr@snark.thyrsus.com> August 1989.

+ * An example of the 'filter()' function in ncurses, this program prompts
+ * for commands and executes them (like a command shell).  It illustrates
+ * how ncurses can be used to implement programs that are not full-screen.
+ *
+ * Ncurses differs slightly from SVr4 curses.  The latter does not flush its
+ * state when exiting program mode, so the attributes on the command lines of
+ * this program 'bleed' onto the executed commands.  Rather than use the
+ * reset_shell_mode() and reset_prog_mode() functions, we could invoke endwin()
+ * and refresh(), but that does not work any better.

+.SH NAME
+gdc \- grand digital clock (curses)
+.SH SYNOPSIS
+.B gdc \fP[\fIoptions\fP] [\fIn\fP]
+.SH DESCRIPTION
+.I Gdc
+runs a digital clock made of reverse-video blanks on a terminal screen.
+If the terminal supports color, the clock is drawn in red.
+You can make the clock stop, pause or resume by pressing a ``q'',
+``s'' or space, respectively.
+.SH OPTIONS
+.TP
+.B \-d
+use terminal's default colors for the background.
+.TP
+.B \-n
+redirects input to /dev/null, making it ignore the stop/pause commands.
+You can still stop it by pressing the interrupt key.
+.TP
+.B \-s
+makes digits scroll as they change.
+When running on a fast display, the program breaks up the scrolling into
+subsecond repaints, making the operation appear smooth.
+.TP
+.B \-t \fIhh:mm:ss\fP
+specify starting time (default is ``now'').
+.PP
+With an optional numeric argument
+.I num
+it stops after
+.I num
+seconds.
+Normally it runs "forever" (counting down from 2 billion seconds).
+.SH AUTHOR
+Amos Shapir, modified for curses by John Lupien.
+.br
+Improvements for ncurses by Thomas Dickey.

+ *		'hanoi'		will give a manual game with 7 playing pieces.
+ *		'hanoi n'	will give a manual game with n playing pieces.
+ *		'hanoi n a' will give an auto solved game with n playing pieces.

+ * Note: to provide inputs for *ins_wch(), we use setcchar().  A quirk of the
+ * X/Open definition for that function is that the string contains no
+ * characters with negative width.  Any control character (such as tab) falls
+ * into that category.  So it follows that *ins_wch() cannot render a tab
+ * character because there is no legal way to construct a cchar_t containing
+ * one.  X/Open does not document this, and it would be logical to assume that
+ * *ins_wstr() has the same limitation, but it uses a wchar_t string directly,
+ * and does not document how tabs are handled.

+ * Demonstrate the waddwchstr() and wadd_wch functions.
+ * Thomas Dickey - 2009/9/12
+ *
+ * Note: to provide inputs for *add_wch(), we use setcchar().  A quirk of the
+ * X/Open definition for that function is that the string contains no
+ * characters with negative width.  Any control character (such as tab) falls
+ * into that category.  So it follows that *add_wch() cannot render a tab
+ * character because there is no legal way to construct a cchar_t containing
+ * one.  X/Open does not document this, and it would be logical to assume that
+ * *addwchstr() has the same limitation, but it uses a wchar_t string directly,
+ * and does not document how tabs are handled.

+ * Demonstrate the waddwstr() and wadd_wch functions.
+ * Thomas Dickey - 2009/9/12
+ *
+ * Note: to provide inputs for *add_wch(), we use setcchar().  A quirk of the
+ * X/Open definition for that function is that the string contains no
+ * characters with negative width.  Any control character (such as tab) falls
+ * into that category.  So it follows that *add_wch() cannot render a tab
+ * character because there is no legal way to construct a cchar_t containing
+ * one.  X/Open does not document this, and it would be logical to assume that
+ * *addwstr() has the same limitation, but it uses a wchar_t string directly,
+ * and does not document how tabs are handled.

+/*
+ * view.c -- a silly little viewer program
+ *
+ * written by Eric S. Raymond <esr@snark.thyrsus.com> December 1994
+ * to test the scrolling code in ncurses.
+ *
+ * modified by Thomas Dickey <dickey@clark.net> July 1995 to demonstrate
+ * the use of 'resizeterm()', and May 2000 to illustrate wide-character
+ * handling.  This program intentionally does not use pads, to allow testing
+ * with less-capable implementations of curses.
+ *
+ * Takes a filename argument.  It's a simple file-viewer with various
+ * scroll-up and scroll-down commands.
+ *
+ * n	-- scroll one line forward
+ * p	-- scroll one line back
+ *
+ * Either command accepts a numeric prefix interpreted as a repeat count.
+ * Thus, typing `5n' should scroll forward 5 lines in the file.
+ *
+ * The way you can tell this is working OK is that, in the trace file,
+ * there should be one scroll operation plus a small number of line
+ * updates, as opposed to a whole-page update.  This means the physical
+ * scroll operation worked, and the refresh() code only had to do a
+ * partial repaint.

+  traces will be dumped.  The program stops and waits for one character of

+# This illustrates the predefined colors for xterm's "xterm-88color" feature.
+# If you set $TERM to "xterm-88color" (and have xterm compiled to support the
+# 88-color or 256-color feature), you can use the ncurses 'd' screen to
+# manipulate the colors shown in the screen.  The 'd' screen is limited to
+# the first 16 colors, and xterm happens to use the same first 16 colors in
+# the extended color models that support initc.
+#
+# The colors shown are for xterm patch #192.
