1     UDPEchoServer echoserver(SocketAddress("localhost",6000));
2     echoserver.run();

2、udpclient

1         UDPEchoServer echoServer;
2         DatagramSocket ss;
3         ss.connect(SocketAddress("localhost", echoServer.port()));//连接
4         int n = ss.sendBytes("hello", 5);//发送
5         char buffer[256];
6         n = ss.receiveBytes(buffer, sizeof(buffer));//udp client接收
7         printf("n = %d\n",n);
