memory_order Enum

Supplies symbolic names for synchronization operations on memory locations. These operations affect how assignments in one thread become visible in another.

typedef enum memory_order {
   memory_order_relaxed,
   memory_order_consume,
   memory_order_acquire,
   memory_order_release,
   memory_order_acq_rel,
   memory_order_seq_cst,
} memory_order;

Remarks

memory_order_relaxed	No ordering required.
memory_order_consume	A load operation acts as a consume operation on the memory location.
memory_order_acquire	A load operation acts as an acquire operation on the memory location.
memory_order_release	A store operation acts as a release operation on the memory location.
memory_order_acq_rel	Combines memory_order_acquire and memory_order_release.
memory_order_seq_cst	Combines memory_order_acquire and memory_order_release. Memory accesses that are marked as memory_order_seq_cst must be sequentially consistent.
