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.
