XS_CLOSE(3) Crossroads I/O Manual XS_CLOSE(3)

xs_close - close Crossroads socket

int xs_close (void *socket);

The xs_close() function shall destroy the socket referenced by the socket argument. Any outstanding messages physically received from the network but not yet received by the application with xs_recv() shall be discarded. The behaviour for discarding messages sent by the application with xs_send() but not yet physically transferred to the network depends on the value of the XS_LINGER socket option for the specified socket.
 
Note
 
 
The default setting of XS_LINGER does not discard unsent messages; this behaviour may cause the application to block when calling xs_term(). For details refer to xs_setsockopt(3) and xs_term(3).

The xs_close() function shall return zero if successful. Otherwise it shall return -1 and set errno to one of the values defined below.

ENOTSOCK
The provided socket was invalid.
