   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

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.
