T fetch_xor( T arg,              std::memory_order order = std::memory_order_seq_cst ) const noexcept;		(since C++20) (member only of atomic_ref<Integral> template specialization)

Atomically replaces the current value of the referenced object with the result of bitwise XOR of the value and arg. This operation is a read-modify-write operation. Memory is affected according to the value of order.

Parameters

arg	-	the other argument of bitwise XOR
order	-	memory order constraints to enforce

Return value

The value of the referenced object, immediately preceding the effects of this function.
