建立订货的非原子和轻松的原子访问的内存同步的指示，
order，在线程和信号处理器，在同一个线程中执行。这是相当于std::atomic_thread_fence，除了没有CPU指令的内存顺序发出。只有由编译器的指示，重新排序可以抑制作为order指示。例如，写入不能移动过去的围栏发布的语义和读取的篱笆，不能提前与收购语义.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.The text has been machine-translated via Google Translate.
