NAME

UDT::Simple - simplified Perl bindings for UDT(reliable UDP based application level data transport protocol - http://udt.sourceforge.net/)

SYNOPSIS

# example server: (using SOCK_DGRAM $client->recv() 
                   will automatically use recvmsg 
                   instead of recv)
my $server = UDT::Simple->new(AF_INET,SOCK_STREAM);
$server->udt_sndbuf(4000);
$server->udt_rcvbuf(4000);
$server->udp_sndbuf(4000);
$server->udp_rcvbuf(4000);
$server->bind("localhost","12344");
$server->listen(4);
while (my $client = $u->accept()) {
   my $data = $client->recv(11);
   $client->close();
}
$server->close();

# example client: (using SOCK_DGRAM $u->send()
                   will automatically use sendmsg
                   instead of send()
my $u = UDT::Simple->new(AF_INET,SOCK_STREAM);
$u->udt_sndbuf(4000);
$u->udt_rcvbuf(4000);
$u->udp_sndbuf(4000);
$u->udp_rcvbuf(4000);

$u->connect("localhost","12344");
# if the socket is SOCK_STREAM send() might not send the whole thing
my $message = "hello world";
my $offset = 0;
while (lenght($message) - $offset > 0) {
    $offset += $u->send($message,$offset);
}
$u->send("hello world")

# if it is SOCK_DGRAM the whole message will be sent
$u->send($message);
$u->close();

INSTALLATION

or download libudt, install it, and run

UDT_INCLUDE=/custom/path/to/udt.h perl Makefile.pl && make && make install

DESCRIPTION

quote from http://udt.sourceforge.net/udt4/index.htm:

UDT is a high performance data transfer protocol - UDP-based
data transfer protocol. It was designed for data intensive 
applications over high speed wide area networks, to overcome
the efficiency and fairness problems of TCP. As its name
indicates, UDT is built on top of UDP and it provides both
reliable data streaming and messaging services.

this module offers incomplete bindings for http://udt.sourceforge.net/, requires libudt see http://udt.sourceforge.net/udt4/index.htm for how to install it.
