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;
