Perl Programmers Reference Guide H2PH(1) NAME h2ph - convert .h C header files to .ph Perl header files SYNOPSIS h2ph [-d destination directory] [-r | -a] [-l] [headerfiles] DESCRIPTION h2ph converts any C header files specified to the corresponding Perl header file format. It is most easily run while in /usr/include: cd /usr/include; h2ph * sys/* or cd /usr/include; h2ph * sys/* arpa/* netinet/* or cd /usr/include; h2ph -r -l . The output files are placed in the hierarchy rooted at Perl's architecture dependent library directory. You can specify a different hierarchy with a -d switch. If run with no arguments, filters standard input to standard output. OPTIONS -d destination_dir Put the resulting .ph files beneath destination_dir, instead of beneath the default Perl library location ($Config{'installsitearch'}). -r Run recursively; if any of headerfiles are directories, then run h2ph on all files in those directories (and their subdirectories, etc.). -r and -a are mutually exclusive. -a Run automagically; convert headerfiles, as well as any .h files which they include. This option will search for .h files in all directories which your C compiler ordinarily uses. -a and -r are mutually exclusive. -l Symbolic links will be replicated in the destination directory. If -l is not specified, then links are skipped over. -h Put ``hints'' in the .ph files which will help in locating problems with h2ph. In those cases when you require a .ph file containing syntax errors, instead of the cryptic [ some error condition ] at (eval mmm) line nnn you will see the slightly more helpful [ some error condition ] at filename.ph line nnn However, the .ph files almost double in size when built using -h. -D Include the code from the .h file as a comment in the .ph file. This is primarily used for debugging h2ph. -Q ``Quiet'' mode; don't print out the names of the files being converted. ENVIRONMENT No environment variables are used. FILES /usr/include/*.h /usr/include/sys/*.h etc. AUTHOR Larry Wall ATTRIBUTES See attributes(5) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | runtime/perl-512 | +---------------+------------------+ |Stability | Uncommitted | +---------------+------------------+ SEE ALSO perl(1) DIAGNOSTICS The usual warnings if it can't read or write the files involved. BUGS Doesn't construct the %sizeof array for you. It doesn't handle all C constructs, but it does attempt to isolate definitions inside evals so that you can get at the definitions that it can translate. It's only intended as a rough tool. You may need to dicker with the files produced. You have to run this program by hand; it's not run as part of the Perl installation. Doesn't handle complicated expressions built piecemeal, a la: enum { FIRST_VALUE, SECOND_VALUE, #ifdef ABC THIRD_VALUE #endif }; Doesn't necessarily locate all of your C compiler's internally-defined symbols.
