void atomic_thread_fence( memory_order order );
(Seit C11)
Stellt Speicher Synchronisierung Bestellung von nicht-atomare und entspannt atomare Zugriffe, wie order angewiesen, ohne einen zugehörigen atomaren Operation. Zum Beispiel werden alle nicht-atomare und entspannt atomaren Läden, die vor einem memory_order_release Zaun in thread geschehen A wird mit nicht-atomare und entspannt atomaren Lasten aus den gleichen Stellen in thread B nach einer memory_order_acquire Zaun gemacht synchronisiert werden .
Original:
Establishes memory synchronization ordering of non-atomic and relaxed atomic accesses, as instructed by order, without an associated atomic operation. For example, all non-atomic and relaxed atomic stores that happen before a memory_order_release fence in thread A will be synchronized with non-atomic and relaxed atomic loads from the same locations made in thread B after an memory_order_acquire fence.
