std::atomic_signal_fence
From Cppreference

| extern "C" void atomic_signal_fence( std::memory_order order );
|
(C++11 feature) | |
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, e.g. writes cannot be moved past std::atomic_signal_fence(std::memory_order_release) and reads cannot be moved ahead of std::atomic_signal_fence(std::memory_order::acquire).
