void atomic_signal_fence( memory_order order ); |
(Seit C11) | |
Stellt Speicher Synchronisierung Bestellung von nicht-atomare und entspannt atomare Zugriffe, wie
order angewiesen, zwischen einem Thread und einem Signal-Handler auf dem gleichen Thread ausgeführt. Dies entspricht std::atomic_thread_fence, außer keine CPU Befehle für Memory Ordnung emittiert. Nur Neuordnung der Instruktionen durch den Compiler unterdrückt wird order anweist. Zum Beispiel schreibt kann nicht über einen Zaun mit Release Semantik verschoben werden und liest nicht vor einem Zaun mit zu erwerben Semantik verschoben werden .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.
