std::atomic::fetch_xor(3)     C++ Standard Libary    std::atomic::fetch_xor(3)

NAME
       std::atomic::fetch_xor -	std::atomic::fetch_xor

Synopsis
	  member only of atomic<Integral> specializations
	  T	fetch_xor(     T     arg,     std::memory_order	    order    =
       (1) (since C++11)
				  std::memory_order_seq_cst ) noexcept;
	  T fetch_xor( T arg, std::memory_order	order =
				  std::memory_order_seq_cst	)     volatile
       (2) (since C++11)
	  noexcept;

	  Atomically replaces the current value	with the result	of bitwise XOR
       of the value
	  and arg. The operation is read-modify-write operation. Memory	is af-
       fected according
	  to the value of order.

	  It is	deprecated if std::atomic<T>::is_always_lock_free is false and
       (since C++20)
	  overload (2) participates in overload	resolution.

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

Return value
	  The  value immediately preceding the effects of this function	in the
       modification
	  order	of *this.

See also
	  atomic_fetch_xor	    replaces the atomic	object with the	result
       of bitwise XOR
	  atomic_fetch_xor_explicit with a non-atomic argument and obtains the
       previous	value
	  (C++11)		    of the atomic
	  (C++11)		    (function template)
