(depuis C11) | |
Établit la synchronisation de mémoire de commande de la non-atomiques et détendue accès atomiques, comme indiqué par
order, entre un thread et un gestionnaire de signal exécutés sur le même thread. Ceci est équivalent à std::atomic_thread_fence, à l'exception d'instructions CPU pour commander la mémoire sont émises. Seulement réorganisation des instructions par le compilateur est supprimé en tant que order instruit. Par exemple, écrit ne peut pas être déplacé au-delà d'une clôture avec une sémantique de libération et lit ne peut pas être passé devant une clôture avec l'acquisition sémantique .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.
