    C atomic_exchange( volatile A* obj, C desired );
    		 (1)
    C atomic_exchange_explicit( volatile A* obj, C desired, memory_order order );
    		 (2)

    Atomically replaces the value pointed by obj with desired and returns the value obj held previously. The operation is read-modify-write operation. The first version orders memory accesses according to memory_order_seq_cst, the second version orders memory accesses according to order.
