Enumerations
enum	RWAtomicMemoryOrder {   rw_mem_order_relaxed, rw_mem_order_consume, rw_mem_order_acquire, rw_mem_order_release,   rw_mem_order_acq_rel, rw_mem_order_seq_cst }

Enumeration Type Documentation

enum RWAtomicMemoryOrder

Specifies the ordering semantics of atomic operations. Specifying memory ordering semantics indicates the minimum ordering constraints on the operation. Implementations may impose stricter ordering constraints.

Enumerator
rw_mem_order_relaxed	No memory ordering is required.
rw_mem_order_consume	Ensure that previous "release" operations on this variable are visible.
rw_mem_order_acquire	Ensure that previous "release" operations on this variable are visible.
rw_mem_order_release	Ensure that changes to this variable are visible to later operations that perform a "consume" or "acquire" operation.
rw_mem_order_acq_rel	Ensure that prior "release" operations on this variable are visible and that changes resulting from this operation are visible to future "consume" and "acquire" operations.
rw_mem_order_seq_cst	Ensure that there is a total ordering of operations. This enforces a "happens before" relationship between all operations on the object.
