ZMQ_CLOSE

Section: 0MQ Manual (3)
Updated: 10/14/2014
Index Return to Main Contents
 

NAME

zmq_close - close 0MQ socket  

SYNOPSIS

int zmq_close (void *socket);  

DESCRIPTION

The zmq_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 zmq_recv() shall be discarded. The behaviour for discarding messages sent by the application with zmq_send() but not yet physically transferred to the network depends on the value of the ZMQ_LINGER socket option for the specified socket.


Note

The default setting of ZMQ_LINGER does not discard unsent messages; this behaviour may cause the application to block when calling zmq_term(). For details refer to zmq_setsockopt(3) and zmq_term(3).

 

RETURN VALUE

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

ERRORS

ENOTSOCK

The provided socket was invalid.
