Defined in header <stdatomic.h>
void atomic_thread_fence( memory_order order );
(C11およびそれ以降)
関連するアトミック操作せず、としてorderによって指示非アトミックとリラックスした不可分なアクセスの順序付けメモリ同期を確立する。たとえば、スレッド内memory_order_releaseフェンスの前に起こるすべての非アトミックとリラックスしたアトミックストアはmemory_order_acquireフェンス後に、スレッドBに作ったのと同じ場所から非原子的でリラックスしたアトミック負荷で同期されます.
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.
