| /* This program massages a system include file (such as stdio.h), |
| into a form that is compatible with GNU C and GNU C++. |
| |
| * extern "C" { ... } braces are added (inside #ifndef __cplusplus), |
| if they seem to be needed. These prevent C++ compilers from name |
| mangling the functions inside the braces. |
| |
| * If an old-style incomplete function declaration is seen (without |
| an argument list), and it is a "standard" function listed in |
| the file sys-protos.h (and with a non-empty argument list), then |
| the declaration is converted to a complete prototype by replacing |
| the empty parameter list with the argument list from sys-protos.h. |
| |
| * The program can be given a list of (names of) required standard |
| functions (such as fclose for stdio.h). If a required function |
| is not seen in the input, then a prototype for it will be |
| written to the output. |
| |
| * If all of the non-comment code of the original file is protected |
| against multiple inclusion: |
| #ifndef FOO |
| #define FOO |
| <body of include file> |
| #endif |
| then extra matter added to the include file is placed inside the <body>. |
| |
| * If the input file is OK (nothing needs to be done); |
| the output file is not written (nor removed if it exists). |
| |
| There are also some special actions that are done for certain |
| well-known standard include files: |
| |
| * If argv[1] is "sys/stat.h", the Posix.1 macros |
| S_ISBLK, S_ISCHR, S_ISDIR, S_ISFIFO, S_ISLNK, S_ISREG are added if |
| they were missing, and the corresponding "traditional" S_IFxxx |
| macros were defined. |
| |
| * If argv[1] is "errno.h", errno is declared if it was missing. |
| |
| * TODO: The input file should be read complete into memory, because: |
| a) it needs to be scanned twice anyway, and |
| b) it would be nice to allow update in place. |
| |
| Usage: |
| fix-header FOO.H INFILE.H OUTFILE.H [OPTIONS] |
| where: |
| * FOO.H is the relative file name of the include file, |
| as it would be #include'd by a C file. (E.g. stdio.h) |
| * INFILE.H is a full pathname for the input file (e.g. /usr/include/stdio.h) |
| * OUTFILE.H is the full pathname for where to write the output file, |
| if anything needs to be done. (e.g. ./include/stdio.h) |
| * OPTIONS can be -D or -I switches as you would pass to cpp. |
