          socket_listen() - listen for connections on a socket

     SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
          #include <socket_err.h>

          int socket_listen( int s, string listen_callback );

          To accept connections, a socket is first created with
          socket_create(3), the socket is them put into listening mode
          with socket_listen(3), and the connections are accepted with
          socket_accept(3). The socket_listen() call applies only to
          sockets of type STREAM or MUD.

          The argument listen_callback is the name of a function for
          the driver to call when a connection is requested on the
          listening socket. The listen callback should follow this
          format:

               void listen_callback(int fd)

          Where fd is the listening socket.
