          socket_write() sends a message on a socket s. If the socket
          s is of type STREAM or MUD, the socket must already be
          connected and the address is not specified. If the socket is
          of type DATAGRAM, the address must be specified.  The
          address is of the form: "127.0.0.1 23".
