| 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><curses.h></STRONG> |
| can be used with the <STRONG>&</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>]. |
| |
| |
| </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 (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 |
| document whether the result string is zero-terminated; it does not doc- |
| ument whether a length limit argument includes any trailing 0; and it |
| does not document the meaning of the return value. |
| |
| |
| </PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE> |
| These functions are described in the XSI Curses standard, Issue 4. It |
| is no more specific than the SVr4 documentation on the trailing 0. It |
| does specify that the successful return of the functions is <STRONG>OK</STRONG>. |
