Function Documentation

int lwip_listen	(	int	s,
		int	backlog
	)

Set a socket into listen mode. The socket may not have been used for another connection previously.

0 on success, non-zero on failure

int lwip_select	(	int	maxfdp1,
		fd_set *	readset,
		fd_set *	writeset,
		fd_set *	exceptset,
		struct timeval *	timeout
	)

Processing exceptset is not yet implemented.

int lwip_shutdown	(	int	s,
