| void atomic_store( volatile A* obj , C desired);

(1) | (since C11) |
| void atomic_store_explicit( volatile A* obj, C desired, memory_order order );
|
(2) | (since C11) |
Atomically replaces the value of the atomic variable pointed to by obj with desired. The operation is atomic write operation.
The first version orders memory accesses according to memory_order_seq_cst, the second version orders memory accesses according to order. order must be one of memory_order_relaxed, memory_order_release or memory_order_seq_cst. Otherwise the behavior is undefined.
This is a generic function defined for all atomic object types. A is the type of an atomic object, C is the non-atomic type corresponding to A.
