19 /* This program massages a system include file (such as stdio.h),
20 into a form that is compatible with GNU C and GNU C++.
21
22 * extern "C" { ... } braces are added (inside #ifndef __cplusplus),
23 if they seem to be needed. These prevent C++ compilers from name
24 mangling the functions inside the braces.
25
26 * If an old-style incomplete function declaration is seen (without
27 an argument list), and it is a "standard" function listed in
28 the file sys-protos.h (and with a non-empty argument list), then
29 the declaration is converted to a complete prototype by replacing
30 the empty parameter list with the argument list from sys-protos.h.
31
32 * The program can be given a list of (names of) required standard
33 functions (such as fclose for stdio.h). If a required function
34 is not seen in the input, then a prototype for it will be
35 written to the output.
36
37 * If all of the non-comment code of the original file is protected
38 against multiple inclusion:
39 #ifndef FOO
40 #define FOO
41 <body of include file>
42 #endif
43 then extra matter added to the include file is placed inside the <body>.
44
45 * If the input file is OK (nothing needs to be done);
46 the output file is not written (nor removed if it exists).
47
48 There are also some special actions that are done for certain
49 well-known standard include files:
50
51 * If argv[1] is "sys/stat.h", the Posix.1 macros
52 S_ISBLK, S_ISCHR, S_ISDIR, S_ISFIFO, S_ISLNK, S_ISREG are added if
53 they were missing, and the corresponding "traditional" S_IFxxx
54 macros were defined.
55
56 * If argv[1] is "errno.h", errno is declared if it was missing.
57
58 * TODO: The input file should be read complete into memory, because:
59 a) it needs to be scanned twice anyway, and
60 b) it would be nice to allow update in place.
61
62 Usage:
63 fix-header FOO.H INFILE.H OUTFILE.H [OPTIONS]
64 where:
65 * FOO.H is the relative file name of the include file,
66 as it would be #include'd by a C file. (E.g. stdio.h)
67 * INFILE.H is a full pathname for the input file (e.g. /usr/include/stdio.h)
68 * OUTFILE.H is the full pathname for where to write the output file,
69 if anything needs to be done. (e.g. ./include/stdio.h)
70 * OPTIONS can be -D or -I switches as you would pass to cpp.
