ZMQ_ATOMIC_COUNTER_N(3) 0MQ Manual ZMQ_ATOMIC_COUNTER_N(3) NAME zmq_atomic_counter_new - create a new atomic counter SYNOPSIS void *zmq_atomic_counter_new (void); DESCRIPTION The zmq_atomic_counter_new function creates a new atomic counter. You can use this in multithreaded applications to do, for example, reference count- ing of shared objects. The atomic counter is at least 32 bits large. This function uses platform specific atomic operations. RETURN VALUE The zmq_atomic_counter_new() function returns the new atomic counter if successful. Otherwise it returns NULL. 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; SEE ALSO zmq_atomic_counter_set(3) zmq_atomic_counter_inc(3) zmq_atomic_counter_dec(3) zmq_atomic_counter_value(3) zmq_atomic_counter_destroy(3) AUTHORS This page was written by the 0MQ community.
