- /* This program massages a system include file (such as stdio.h),
- into a form more conformant with ANSI/POSIX, and more suitable for 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 lust 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 reqquired 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 REQUIRED_FUNCS <SCAN-FILE
- 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)
- * SCAN-FILE is the output of the scan-decls program.
- * REQUIRED_FUNCS is a list of required function (e.g. fclose for stdio.h).
