Defined in header
<atomic>
template< class T >
void atomic_notify_one( std::atomic <T>* object );
(1)
(since C++20)
void atomic_notify_one( std::atomic <T>* object );
template< class T >
void atomic_notify_one( volatile std::atomic <T>* object );
(2)
(since C++20)
void atomic_notify_one( volatile std::atomic <T>* object );
Performs atomic notifying operations.
If there is a thread blocked in atomic waiting operation (i.e. std::atomic_wait() , std::atomic_wait_explicit() , or std::atomic::wait()) on *object, then unblocks at least one such thread; otherwise does nothing.
Equivalent to object->notify_one().

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