(since C++11) | |
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, a fence with release semantics prevents reads or writes from being moved past subsequent writes and a fence with acquire semantics prevents reads or writes from being moved ahead of preceding reads.
