| 18 | /* This program massages a system include file (such as stdio.h), |
---|
[11287] | 19 | into a form that is compatible with GNU C and GNU C++. |
---|
[8833] | 20 | |
---|
| 21 | * extern "C" { ... } braces are added (inside #ifndef __cplusplus), |
---|
| 22 | if they seem to be needed. These prevent C++ compilers from name |
---|
| 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 |
---|
| 29 | the empty parameter list with the argument lust from sys-protos.h. |
---|
| 30 | |
---|
| 31 | * The program can be given a list of (names of) required standard |
---|
| 32 | functions (such as fclose for stdio.h). If a required function |
---|
| 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: |
---|
| 62 | fix-header FOO.H INFILE.H OUTFILE.H [OPTIONS] |
---|
| 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) |
---|
| 69 | * OPTIONS are such as you would pass to cpp. |
