NAME

       zmq_atomic_counter_set - set atomic counter to new value

SYNOPSIS

       void zmq_atomic_counter_set (void *counter, int value);

DESCRIPTION

       The zmq_atomic_counter_set function sets the counter to a new value, in a threadsafe
       fashion. The largest value that is guaranteed to work across all platforms is 2^31-1. This
       function uses platform specific atomic operations.

RETURN VALUE

       The zmq_atomic_counter_set() function has no return value.

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;
