Datagram sockets are available through `require('dgram')`.
+Important note: the behavior of `dgram.Socket#bind()` has changed in v0.10
+and is always asynchronous now. If you have code that looks like this:
+
+ var s = dgram.createSocket('udp4');
+ s.bind(1234);
+ s.addMembership('224.0.0.114');
+
+You have to change it to this:
+
+ var s = dgram.createSocket('udp4');
+ s.bind(1234, function() {
+ s.addMembership('224.0.0.114');
+ });
+
+
## dgram.createSocket(type, [callback])
* `type` String. Either 'udp4' or 'udp6'
