atomic_thread_fence Function

Acts as a fence—which is a memory synchronization primitive that enforces ordering between load/store operations—without an associated atomic operation.

inline void atomic_thread_fence(
   memory_order Order
) _NOEXCEPT;

Parameters

• Order
  A memory ordering constraint that determines fence type.

Remarks

The Order argument determines fence type.

memory_order_relaxed	The fence has no effect.
memory_order_consume	The fence is an acquire fence.
memory_order_acquire	The fence is an acquire fence.
memory_order_release	The fence is a release fence.
memory_order_acq_rel	The fence is both an acquire fence and a release fence.
memory_order_seq_cst	The fence is both an acquire fence and a release fence, and is sequentially consistent.
