Detailed Description
Socket API (to be used from non-TCPIP threads)
Definition in file sockets.h.
Function Documentation
| 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.
Definition at line 2712 of file lwip_sockets.c.
| 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
Definition at line 709 of file lwip_sockets.c.
| int lwip_shutdown | ( | int | s, |
| int | how | ||
| ) |
Close one end of a full-duplex connection.
Definition at line 1691 of file lwip_sockets.c.
| void lwip_socket_thread_cleanup | ( | void | ) |
LWIP_NETCONN_SEM_PER_THREAD==1: destroy thread-local semaphore.
Definition at line 338 of file lwip_sockets.c.
| void lwip_socket_thread_init | ( | void | ) |
LWIP_NETCONN_SEM_PER_THREAD==1: initialize thread-local semaphore.
Definition at line 331 of file lwip_sockets.c.
