          #include <socket_err.h>

          int socket_connect( int s, string address,
                              string read_callback,
                              string write_callback );

          The argument s is a socket. s must be either a STREAM mode
          or a MUD mode socket. address is the address to which the
          socket will attempt to connect.  address is of the form:
          "127.0.0.1 23"

          The argument read_callback is the name of a function for the
          driver to call when the socket gets data from its peer. The
          read callback should follow this format:

               void read_callback(int fd, mixed message)

          Where fd is the socket which received the data, and message
          is the data which was received.

          The argument write_callback is the name of a function for
          the driver to call when the socket is ready to be written
          to. The write callback should follow this format:

               void write_callback(int fd)

          Where fd is the socket which is ready to be written to.
