zmq_atomic_counter_destroy3
Destroy an atomic counter
Usage
void zmq_atomic_counter_destroy (void **counter_p);
Overview
The zmq_atomic_counter_destroy function destroys an atomic counter and nullifies its reference. Pass the address of an atomic counter (void **) rather than the counter itself. You must destroy all counters that you create, to avoid memory leakage. This function uses platform specific atomic operations.
Return value
The zmq_atomic_counter_destroy() function has no return value.
Examples
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;
