     socket_listen() - listen for connections on a socket

SYNOPSIS
     #include <socket_err.h>

     int socket_listen( int s, string listen_callback );

DESCRIPTION
     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.

RETURN VALUES
     socket_listen() returns:

          EESUCCESS on success.

          a negative value indicated below on error.

ERRORS
     EEFDRANGE      Descriptor out of range.

     EEBADF         Descriptor is invalid.

     EESECURITY     Security violation attempted.

     EEMODENOTSUPP  Socket mode not supported.
