Socket UDP Programming Steps

The general steps of the server side of UDP programming are:
1, create a socket, with a function socket ();
3, binding IP address, port and other information to the socket, with the function bind ();
4, the loop receives sends the data, uses the function recvfrom (), sendto ();
5, close the network connection;

The general steps for UDP programming clients are:
1, create a socket, with a function socket ();
2, set the other IP address and port properties;
3, connect the server, with function connect ();
If the data is sent and received only once, this function can not be used;
If the loop sends the receive, then uses the Connect function here, because if does not have, when sendto () then after the server kill, then the client side is blocked at the Recvfrom place;
4, the loop sends receives the data, uses the function sendto (), recvfrom ();
5, close the network connection;
