SELWAIT_T

#define SELWAIT_T   u8_t

This is overridable for the rare case where more than 255 threads select on the same socket...

Function Documentation

lwip_fcntl()

int lwip_fcntl	(	int	s,
		int	cmd,
		int	val
	)

A minimal implementation of fcntl. Currently only the commands F_GETFL and F_SETFL are implemented. Only the flag O_NONBLOCK is implemented.

lwip_listen()

int lwip_listen	(	int	s,
		int	backlog
	)

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

Parameters

s	the socket to set to listening mode
backlog	(ATTENTION: needs TCP_LISTEN_BACKLOG=1)

Returns

0 on success, non-zero on failure

lwip_shutdown()

int lwip_shutdown	(	int	s,
		int	how
	)

Close one end of a full-duplex connection.
