Create a connectionless pair of sockets that can communicate with each other without specifying any addresses in their I/O operations
=====================================================================================================================================

#. Open ``SOCK_DGRAM`` socket ``srvr_s`` on ``srvr`` and bind it to ``srvr_addr`` address;

#. Open ``SOCK_DGRAM`` socket ``clnt_s`` on ``clnt`` and bind it to to ``clnt_addr`` address;

#. **connect()** ``clnt_s`` socket to ``srvr_s`` socket;

#. **connect()** ``srvr_s`` socket to ``clnt_s`` socket.
