NAME
FFI::Library - Perl Access to Dynamically Loaded Libraries
VERSION
version 0.05
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 and better maintained FFI modules such as FFI::Platypus provide more functionality and should probably be considered for new projects.
CONSTRUCTOR
new
my $lib = FFI::Library->new($libname);Creates an instance of FFI::Library.
FUNCTIONS
address
my $address = $lib->address($function_name);Returns the symbol of the given function. Returns undef if the symbol is not found.
function
my $sub = $lib->function($function_name, $signature);Creates a code-reference like object which you can call.
EXAMPLES
$clib_file = ($^O eq "MSWin32") ? "MSVCRT40.DLL" : "-lc";
$clib = FFI::Library->new($clib_file);
$strlen = $clib->function("strlen", "cIp");
$n = $strlen->($my_string);SUPPORT
