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.
| int lwip_listen | ( | int | s, | 
| int | backlog | ||
| ) | 
Set a socket into listen mode. The socket may not have been used for another connection previously.
| s | the socket to set to listening mode | 
| backlog | (ATTENTION: needs TCP_LISTEN_BACKLOG=1) | 
| int lwip_shutdown | ( | int | s, | 
| int | how | ||
| ) | 
Close one end of a full-duplex connection.
