Node.js: UDP client (that should wait for a response before closing)

nodejs-udpclient.js

var dgram = require('dgram');

sendUDPMessage("10.1.2.3", 1234, Buffer("Release The Kraken!"));

function sendUDPMessage(targetIP, targetPORT, message){

  var client = dgram.createSocket("udp4");

  client.on('error', function(e) {
      throw e;
  });

  client.on("message", function (msg, rinfo) {
    console.log("got: \t" + msg + "\t from\t" + rinfo.address + ":" + rinfo.port);
    client.close();
  });

  client.send(message, 0, message.length, targetPORT, targetIP, function(err, bytes) {});

}
