ZMQ_ATOMIC_COUNTER_V(3)           0MQ Manual           ZMQ_ATOMIC_COUNTER_V(3)

NAME
       zmq_atomic_counter_value - return value of atomic counter

SYNOPSIS
       int zmq_atomic_counter_value (void *counter);

DESCRIPTION
       The zmq_atomic_counter_value function returns the value of an atomic
       counter created by zmq_atomic_counter_new(). This function uses
       platform specific atomic operations.

RETURN VALUE
       The zmq_atomic_counter_value() function returns the value of the atomic
       counter. If counter does not point to an atomic counter created by
       zmq_atomic_counter_new(), the behaviour is undefined.

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;
