Detailed Description

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

Definition in file sockets.h.

Function Documentation

A minimal implementation of fcntl.

Currently only the commands F_GETFL and F_SETFL are implemented. Only the flag O_NONBLOCK is implemented.

Definition at line 2712 of file lwip_sockets.c.

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)

Definition at line 709 of file lwip_sockets.c.

Close one end of a full-duplex connection.
