DDEESSCCRRIIPPTTIIOONN
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.
