0MQ 4.3.5                                          03/31/2024                            ZMQ_ATOMIC_COUNTER_N(3)

       The zmq_atomic_counter_new function creates a new atomic counter. You can use this in multithreaded
       applications to do, for example, reference counting of shared objects. The atomic counter is at least 32
       bits large. This function uses platform specific atomic operations.

           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_new - create a new atomic counter

       The zmq_atomic_counter_new() function returns the new atomic counter if successful. Otherwise it returns
       NULL.
