=head1 NAME

h2ph - convert .h C header files to .ph Perl header files

=head1 SYNOPSIS

B<h2ph [-d destination directory] [-r | -a] [-l] [-h] [-e] [-D] [-Q]
[headerfiles]>

=head1 DESCRIPTION

I<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 * sys/* arpa/* netinet/*

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 B<-d> switch.

If run with no arguments, filters standard input to standard output.

=head1 OPTIONS

=over 4

=item -d destination_dir

Put the resulting B<.ph> files beneath B<destination_dir>, instead of
beneath the default Perl library location (C<$Config{'installsitearch'}>).

=item -r

Run recursively; if any of B<headerfiles> are directories, then run I<h2ph>
on all files in those directories (and their subdirectories, etc.).  B<-r>
and B<-a> are mutually exclusive.

=item -a

Run automagically; convert B<headerfiles>, as well as any B<.h> files
which they include.  This option will search for B<.h> files in all
directories which your C compiler ordinarily uses.  B<-a> and B<-r> are
mutually exclusive.

=item -l

Symbolic links will be replicated in the destination directory.  If B<-l>
is not specified, then links are skipped over.

=item -h

Put 'hints' in the .ph files which will help in locating problems with
I<h2ph>.  In those cases when you B<require> a B<.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 B<.ph> files almost double in size when built using B<-h>.

=item -e

If an error is encountered during conversion, output file will be removed and
a warning emitted instead of terminating the conversion immediately.

=item -D

Include the code from the B<.h> file as a comment in the B<.ph> file.
This is primarily used for debugging I<h2ph>.

=item -Q

'Quiet' mode; don't print out the names of the files being converted.

=back

=head1 ENVIRONMENT

No environment variables are used.

=head1 FILES

/usr/include/*.h
 /usr/include/sys/*.h

etc.

=head1 AUTHOR

Larry Wall

=head1 SEE ALSO

perl(1)

=head1 DIAGNOSTICS

The usual warnings if it can't read or write the files involved.

=head1 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.
