std::atomic_ref::notify_one(3)

NAME
std::atomic_ref::notify_one - std::atomic_ref::notify_one

Synopsis
   void notify_one() const noexcept; (since C++20)
   void notify_one() const 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.
