Defined in header <stdatomic.h>
void atomic_signal_fence( memory_order order );
(C11およびそれ以降)
スレッドと同じスレッドで実行されるシグナルハンドラとの間で、orderによって指示されるように、非原子的でリラックスしたアトミックアクセスの順序メモリ同期を確立する。これは、メモリの順序のためのCPU命令が発行されていない場合を除き、std::atomic_thread_fenceに相当します。 orderが指示としてコンパイラによる命令の並べ替えだけでは抑制されます。たとえば、リリースのセマンティクスでフェンスを越えて移動することはできません書き込みと読み出しのセマンティクスを取得すると前方にフェンスの移動はできません.
Original:
Establishes memory synchronization ordering of non-atomic and relaxed atomic accesses, as instructed by order, between a thread and a signal handler executed on the same thread. This is equivalent to std::atomic_thread_fence, except no CPU instructions for memory ordering are issued. Only reordering of the instructions by the compiler is suppressed as order instructs. For example, writes cannot be moved past a fence with release semantics and reads cannot be moved ahead of a fence with acquire semantics.
