ZMQ_ATOMIC_COUNTER_D(3) 0MQ Manual ZMQ_ATOMIC_COUNTER_D(3) NAME zmq_atomic_counter_dec - decrement an atomic counter SYNOPSIS int zmq_atomic_counter_dec (void *counter); DESCRIPTION The zmq_atomic_counter_dec function decrements an atomic counter in a threadsafe fashion. This function uses platform specific atomic operations. RETURN VALUE The zmq_atomic_counter_dec() function returns 1 if the counter is greater than zero after decrementing, or zero if the counter reached zero. 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_set(3) zmq_atomic_counter_inc(3) zmq_atomic_counter_value(3) zmq_atomic_counter_destroy(3) AUTHORS This page was written by the 0MQ community.
