18 | /* This program massages a system include file (such as stdio.h), | |
9e04c65a | 19 | into a form that is compatible with GNU C and GNU C++. |
7936052f PB |
20 | |
21 | * extern "C" { ... } braces are added (inside #ifndef __cplusplus), | |
05227b51 | 22 | if they seem to be needed. These prevent C++ compilers from name |
7936052f PB |
23 | mangling the functions inside the braces. |
24 | ||
25 | * If an old-style incomplete function declaration is seen (without | |
26 | an argument list), and it is a "standard" function listed in | |
27 | the file sys-protos.h (and with a non-empty argument list), then | |
28 | the declaration is converted to a complete prototype by replacing | |
081f5e7e | 29 | the empty parameter list with the argument list from sys-protos.h. |
7936052f PB |
30 | |
31 | * The program can be given a list of (names of) required standard | |
9faa82d8 | 32 | functions (such as fclose for stdio.h). If a required function |
7936052f PB |
33 | is not seen in the input, then a prototype for it will be |
34 | written to the output. | |
35 | ||
36 | * If all of the non-comment code of the original file is protected | |
37 | against multiple inclusion: | |
38 | #ifndef FOO | |
39 | #define FOO | |
40 | <body of include file> | |
41 | #endif | |
42 | then extra matter added to the include file is placed inside the <body>. | |
43 | ||
44 | * If the input file is OK (nothing needs to be done); | |
45 | the output file is not written (nor removed if it exists). | |
46 | ||
47 | There are also some special actions that are done for certain | |
48 | well-known standard include files: | |
49 | ||
50 | * If argv[1] is "sys/stat.h", the Posix.1 macros | |
51 | S_ISBLK, S_ISCHR, S_ISDIR, S_ISFIFO, S_ISLNK, S_ISREG are added if | |
52 | they were missing, and the corresponding "traditional" S_IFxxx | |
53 | macros were defined. | |
54 | ||
55 | * If argv[1] is "errno.h", errno is declared if it was missing. | |
56 | ||
57 | * TODO: The input file should be read complete into memory, because: | |
58 | a) it needs to be scanned twice anyway, and | |
59 | b) it would be nice to allow update in place. | |
60 | ||
61 | Usage: | |
b3ca463c | 62 | fix-header FOO.H INFILE.H OUTFILE.H [OPTIONS] |
7936052f PB |
63 | where: |
64 | * FOO.H is the relative file name of the include file, | |
65 | as it would be #include'd by a C file. (E.g. stdio.h) | |
66 | * INFILE.H is a full pathname for the input file (e.g. /usr/include/stdio.h) | |
67 | * OUTFILE.H is the full pathname for where to write the output file, | |
68 | if anything needs to be done. (e.g. ./include/stdio.h) | |
b3ca463c | 69 | * OPTIONS are such as you would pass to cpp. |
