            Construct a basic_seq_packet_socket without
            opening it.
          
basic_seq_packet_socket( asio::io_service & io_service);
This constructor creates a sequenced packet socket without opening it. The socket needs to be opened and then connected or accepted before data can be sent or received on it.
                  The io_service
                  object that the sequenced packet socket will use to dispatch handlers
                  for any asynchronous operations performed on the socket.
