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;
