NAME¶

std::atomic_signal_fence - std::atomic_signal_fence

Synopsis¶

Defined in header <atomic>
extern "C" void atomic_signal_fence( std::memory_order order ) (since C++11)
noexcept;

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.

Parameters¶

order - the memory ordering executed by this fence

Return value¶

(none)
