NAME
       std::atomic_ref::fetch_or - std::atomic_ref::fetch_or

Synopsis
	  T fetch_or( T	arg,				  (since C++20)
	  std::memory_order  order  =			     (member  only  of
       atomic_ref<Integral>
	  std::memory_order_seq_cst ) const noexcept;	  template specializa-
       tion)

	  Atomically replaces the current value	of the referenced object  with

       write operation.
	  Memory is affected according to the value of order.

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

Return value
	  The value of the referenced object, immediately  preceding  the  ef-
       fects of	this
	  function.
