Connecting To A Server

After we create the socket, we need to connect it to the server. This is required because the TCP protocol is connection oriented.


 /* now connect to the remote server. the system will   */
 /* choose a free port number for the local side of the */
 /* connection.                                         */
 /* note the cast to a struct sockaddr pointer of the   */
 /* address of variable 'sa'.                           */
 if (connect(s, (struct sockaddr *)&sa, sizeof(sa)) ) {
     perror("connect");
     exit(1);
 }
