zmq_atomic_counter_new(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 counting 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 -------- linkzmq:zmq_atomic_counter_set[3] linkzmq:zmq_atomic_counter_inc[3] linkzmq:zmq_atomic_counter_dec[3] linkzmq:zmq_atomic_counter_value[3] linkzmq:zmq_atomic_counter_destroy[3] AUTHORS ------- This page was written by the 0MQ community.
