Defined in header <stdatomic.h>
void atomic_thread_fence( memory_order order );
(desde C11)
Estabelece a sincronização de memória ordenação de não-atômicas e relaxado acessos atômicas, conforme instruções order, sem uma operação associada atômica. Por exemplo, todas as lojas não-atômicas e relaxado atômicas que acontecem antes de uma cerca memory_order_release no segmento A será sincronizado com os não-atômicas e relaxado cargas atômicas dos mesmos locais feitas no segmento B, após uma cerca memory_order_acquire.
Original:
Establishes memory synchronization ordering of non-atomic and relaxed atomic accesses, as instructed by order, without an associated atomic operation. For example, all non-atomic and relaxed atomic stores that happen before a memory_order_release fence in thread A will be synchronized with non-atomic and relaxed atomic loads from the same locations made in thread B after an memory_order_acquire fence.
