/* 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).
