void atomic_signal_fence(memory_order order); | (since C11) | |
Establishes memory synchronization ordering of non-atomic and relaxed atomic accesses, as instructed byorder, between a thread and a signal handler executed on the same thread. This is equivalent toatomic_thread_fence, except no CPU instructions for memory ordering are issued. Only reordering of the instructions by the compiler is suppressed asorder 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.
