NAME
       P2P::pDonkey::Packet - Perl extension for handling packets of eDonkey
       peer2peer protocol.

SYNOPSIS
           use P2P::pDonkey::Meta qw( makeClientInfo printInfo );
           use P2P::pDonkey::Packet ':all';
           use Data::Hexdumper;

           my $user = makeClientInfo(0, 4662, 'Muxer', 60);
           my $raw = packBody(PT_HELLO, $user);
           print hexdump(data => $raw);

           my ($off, $pt) = (0);
           $user = unpackBody(\$pt, $raw, $off);
           print "Packet type: ", PacketTagName($pt), "\n";
           printInfo($user);

DESCRIPTION
       The module provides functions and constants for creating, packing and
       unpacking packets of eDonkey peer2peer protocol.

       PacketTagName(PT_TAG)
               Returns string name of PT_TAG or 'Unknown(PT_TAG)' if name is unknown.

       unpackBody(\$pt, $data, $offset)
               Unpacks data and places packet type in $pt. $offset is changed to last
               unpacked byte offset in $data. Packet header is not processed in
               unpackBody(), so $offset should be set on packet type byte offset.
               Returns list of unpacked data in success.

       packBody(PT_TAG, ...)
               Packs user data in packet with PT_TAG type and returns byte string.
               packet header is not included in result.

       unpackUDPHeader($data, $offset)
               Returns 1 if data starts with PT_HEADER byte.

       packUDPHeader()
               Returns packed PT_HEADER byte.

       unpackTCPHeader($data, $offset)
               Unpacks header and returns length of the following packet body.

       packTCPHeader($length)
               Returns packed header.

       eDonkey packet types

           Here listed data, returned by unpackBody() and passed to packBody()
           for each packet type.

       EXPORT

       None by default.
