atomic::fetch_or Method
Performs a bitwise or on a value and an existing value that is stored in *this.
Ty atomic<Ty>::fetch_or (
Ty Value,
memory_order Order = memory_order_seq_cst
) volatile _NOEXCEPT;
Ty atomic<Ty>::fetch_or (
Ty Value,
memory_order Order = memory_order_seq_cst
) _NOEXCEPT;
Parameters
Value
A value of type Ty.Order
A memory_order.
Return Value
A Ty object that contains the result of the bitwise or.
Remarks
The fetch_or method performs a read-modify-write operation to replace the stored value of *this with a bitwise or of Value and the current value that is stored in *this, within the memory constraints that are specified by Order.
