zmq_flush(3) ============ NAME ---- zmq_flush - flushes pre-sent messages to the socket SYNOPSIS -------- 'int zmq_flush (void *s);' DESCRIPTION ----------- Flushes all the pre-sent messages - i.e. those that have been sent with ZMQ_NOFLUSH flag - to the socket. This functionality improves performance in cases where several messages are sent during a single business operation. It should not be used as a transaction - ACID properties are not guaranteed. Note that calling 'zmq_send' without ZMQ_NOFLUSH flag automatically flushes all previously pre-sent messages. RETURN VALUE ------------ In case of success the function returns zero. Otherwise it returns -1 and sets 'errno' to the appropriate value. ERRORS ------ *ENOTSUP*:: function isn't supported by particular socket type. *EFSM*:: function cannot be called at the moment, because socket is not in the approprite state. EXAMPLE ------- ---- rc = zmq_send (s, &msg1, ZMQ_NOFLUSH); assert (rc == 0); rc = zmq_send (s, &msg2, ZMQ_NOFLUSH); assert (rc == 0); rc = zmq_flush (s); assert (rc == 0); ---- SEE ALSO -------- linkzmq:zmq_send[3] AUTHOR ------ Martin Sustrik
