ZMQ_ATOMIC_COUNTER_S(3) 	   0MQ Manual		 ZMQ_ATOMIC_COUNTER_S(3)

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  opera-
     tions.

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;
