NAME

FFI::Library - Perl Access to Dynamically Loaded Libraries

SYNOPSIS

use FFI::Library;
$lib = FFI::Library->new("mylib");
$fn = $lib->function("fn", "signature");
$ret = $fn->(...);

DESCRIPTION

This module provides access from Perl to functions exported from dynamically linked libraries. Functions are described by signatures, for details of which see the FFI module's documentation.

Newer FFI modules such as FFI::Platypus and FFI::Raw provide more functionality and should probably be considered for new projects.

EXAMPLES

$clib_file = ($^O eq "MSWin32") ? "MSVCRT40.DLL" : "-lc";
$clib = FFI::Library->new($clib_file);
$strlen = $clib->function("strlen", "cIp");
$n = $strlen->($my_string);
