h2ph - convert .h C header files to .ph Perl header files
h2ph [-d destination directory] [-r] [-l] [headerfiles]
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/*
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.
- -d destination_dir
Put the resulting .ph files beneath destination_dir, instead of beneath the default Perl library location (
Run recursively; if any of headerfiles are directories, then run h2ph on all files in those directories (and their subdirectories, etc.).
Symbolic links will be replicated in the destination directory. If -l is not specified, then links are skipped over.
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.
No environment variables are used.
The usual warnings if it can't read or write the files involved.
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.
