NAME ^

Alien::FFCall - Alien library for FFCall

SYNOPSIS ^

I would encourage you to look at FFI.pm if you want a Perl-level wrapper to FFCall. However, if you want to write your own XS-based interface to FFCall, your Build.PL file should say:

 use strict;
 use warnings;
 use Module::Build;
 use Alien::FFCall;
 
 # Retrieve the Alien::FFCall configuration:
 my $alien = Alien::FFCall->new;
 
 # Create the build script:
 my $builder = Module::Build->new(
     module_name => 'My::FFCall::Wrapper',
     extra_compiler_flags => $alien->cflags(),
     extra_linker_flags => $alien->libs(),
     configure_requires => {
         'Alien::FFCall' => 0,
     },
 );
 $builder->create_build_script;

Your module (.pm) file should look like this:

 package My::FFCall::Wrapper;
 
 use strict;
 use warnings;
 
 use Alien::FFCall;
 
 our $VERSION = '0.01';
 
 require XSLoader;
 XSLoader::load('My::FFCall::Wrapper');
 
 ... perl-level code goes here ...

Your XS file should look like this:

 #include "EXTERN.h"
 #include "perl.h"
 #include "XSUB.h"
 
 #include <avcall.h>
 #include <callback.h>
 
 ... normal XS stuff goes here, making use of the FFCall API ...

DESCRIPTION ^

Alien::FFCall provides a CPAN distribution for the FFCall library. In other words, it installs FFCall's library in a non-system folder and provides you with the details necessary to include in and link to your C/XS code.

For documentation on the FFCall's API, see http://www.haible.de/bruno/packages-ffcall.html.

BUGS ^

The best place to report bugs or get help for this module is to file Issues on github:

Note that I do not maintain FFCall itself, only the Alien module for it. As I understand it, FFCall is no longer maintained. :-(
