socket_listen() - listen for connections on a socket


#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.


socket_listen() returns:

    EESUCCESS on success.

    a negative value indicated below on error.


EEFDRANGE      Descriptor out of range.

EEBADF         Descriptor is invalid.

EESECURITY     Security violation attempted.

EEMODENOTSUPP  Socket mode not supported.

EENOADDR       Socket not bound to an address.

EEISCONN       Socket is already connected.

EELISTEN       Problem with listen.
