                    | Defined in header  <stdatomic.h> | ||
| void atomic_thread_fence( memory_order order ); | (since C11) | |
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.
Parameters
| order | - | the memory ordering executed by this fence | 
Return value
(none)
