NAME

Media::LibMTP::API - Low-level interface to libmtp

VERSION

This document describes version 0.03 of Media::LibMTP::API, released July 4, 2012 as part of Media-LibMTP-API version 0.03.

SYNOPSIS

  use Media::LibMTP::API qw(Get_First_Device);
  my $device = Get_First_Device() or die;
  say $device->Get_Friendlyname;

DESCRIPTION

Media::LibMTP::API provides a low-level interface to libmtp (http://libmtp.sourceforge.net), which is an Initiator implementation of the Media Transfer Protocol (MTP) in the form of a library suitable primarily for POSIX compliant operating systems.

libmtp is not included with Media::LibMTP::API; you must install it separately.

Media::LibMTP::API is a thin wrapper around libmtp. It follows the libmtp API closely, even when that's not very Perlish. For example, many functions return 0 on success. Media::LibMTP will be a higher-level, more Perl-like interface built on top of Media::LibMTP::API, but it's not yet ready for release. You can follow or help with Media::LibMTP's development at https://github.com/madsen/media-libmtp.

This module is not well documented. Consult the libmtp documentation (which can be generated by Doxygen, and should have been installed along with libmtp). All functions that take a pointer to a libmtp struct as their first parameter are implemented as a method on the corresponding Perl object. Not all functions are currently implemented; consult the source for details.

Many libmtp functions return a linked list of structures. In Media::LibMTP::API, you get the next struct by calling an accessor method. You must preserve the reference to the first struct returned by libmtp until you are done with all the structures in the list, because when that reference is dropped, the entire list will be deleted. This is the purpose of the AlbumList, FileList, FolderList, MTPDeviceList, PlaylistList, and TrackList subclasses: they have a destructor that cleans up the list. For example, the Get_Album_List method returns an AlbumList object (a subclass of Album), but $album->next returns an Album object.
