Synopsis

Create a Listening Socket:

var mdgram=require('mdgram');
var socket=mdgram.createSocket('udp4');
socket.bind(1234);
socket.joinGroup("225.0.0.73");

Setting the Multicast TimeToLive:

socket.setMulticastTTL(5);

Setting the Multicast Interface:

socket.setMulticastInterface("192.168.0.3"); // Where 192.168.0.3 is the IP of the interface you want to use Multicast on
socket.setMulticastInterface(); // If you want the system to figure out which to use (commonly the first non-loopback interface)

Leaving a Multicast Group:

socket.leaveGroup("225.0.0.73");
