NAME
       std::atomic_notify_all -	std::atomic_notify_all

Synopsis
	  Defined in header <atomic>
	  template<   class   T	 >					   (1)
       (since C++20)
	  void atomic_notify_all( std::atomic<T>* object );
	  template<  class  T	>					   (2)
       (since C++20)
	  void atomic_notify_all( volatile std::atomic<T>* object );

	  Performs atomic notifying operations.

	  Unblocks  all	 threads  blocked  in  atomic waiting operations (i.e.
       std::atomic_wait(),
	  std::atomic_wait_explicit(), or std::atomic::wait()) on *object,  if
       there are any;
	  otherwise does nothing.

	  Equivalent to	object->notify_all().

Parameters
	  object - pointer to the atomic object	to notify

Return value
	  (none)

Notes
	  This	form  of  change-detection is often more efficient than	simple
       polling or pure
	  spinlocks.
