Detailed Description

Socket API (to be used from non-TCPIP threads)

Macro Definition Documentation

◆ LWIP_TIMEVAL_PRIVATE

#define LWIP_TIMEVAL_PRIVATE 1

LWIP_TIMEVAL_PRIVATE: if you want to use the struct timeval provided by your system, set this to 0 and include <sys/time.h> in cc.h

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. The flag O_NONBLOCK and access modes are supported for F_GETFL, only the flag O_NONBLOCK is implemented for F_SETFL.

◆ 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.

◆ lwip_socket_thread_cleanup()

void lwip_socket_thread_cleanup ( void )

LWIP_NETCONN_SEM_PER_THREAD==1: destroy thread-local semaphore

◆ lwip_socket_thread_init()

void lwip_socket_thread_init ( void )

LWIP_NETCONN_SEM_PER_THREAD==1: initialize thread-local semaphore
