ZMQ_ATOMIC_COUNTER_S(3) 0MQ Manual ZMQ_ATOMIC_COUNTER_S(3) NAME zmq_atomic_counter_set - set atomic counter to new value SYNOPSIS void zmq_atomic_counter_set (void *counter, int value); DESCRIPTION The zmq_atomic_counter_set function sets the counter to a new value, in a threadsafe fashion. The largest value that is guaranteed to work across all platforms is 2^31-1. This function uses platform specific atomic operations. RETURN VALUE The zmq_atomic_counter_set() function has no return value. EXAMPLE Test code for atomic counters. void *counter = zmq_atomic_counter_new (); assert (zmq_atomic_counter_value (counter) == 0); assert (zmq_atomic_counter_inc (counter) == 0); assert (zmq_atomic_counter_inc (counter) == 1); assert (zmq_atomic_counter_inc (counter) == 2); assert (zmq_atomic_counter_value (counter) == 3); assert (zmq_atomic_counter_dec (counter) == 1); assert (zmq_atomic_counter_dec (counter) == 1); assert (zmq_atomic_counter_dec (counter) == 0); zmq_atomic_counter_set (counter, 2); assert (zmq_atomic_counter_dec (counter) == 1); assert (zmq_atomic_counter_dec (counter) == 0); zmq_atomic_counter_destroy (&counter); return 0; SEE ALSO zmq_atomic_counter_new(3) zmq_atomic_counter_inc(3) zmq_atomic_counter_dec(3) zmq_atomic_counter_value(3) zmq_atomic_counter_destroy(3) AUTHORS This page was written by the 0MQ community.
