int lwip_fcntl ( int  s,

A minimal implementation of fcntl.

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

int lwip_listen ( int  s,

Set a socket into listen mode.

The socket may not have been used for another connection previously.

sthe socket to set to listening mode

Returns
0 on success, non-zero on failure
