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

NAME
       std::atomic::notify_one - std::atomic::notify_one

Synopsis
	  void notify_one() noexcept;		(since C++20)
	  void notify_one() volatile noexcept;

	  Performs atomic notifying operations.

	  If  there  is	 a  thread  blocked  in	atomic waiting operation (i.e.
       wait()) on *this,
	  then unblocks	at least one such thread; otherwise does nothing.

Return value
	  (none)

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