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.

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.
