atomic_flag::notify_one
(C++20)
(C++20)
void notify_one() noexcept;
(1)
(since C++20) (constexpr since C++26)
void notify_one() volatile noexcept;
(2)
(since C++20)
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.
[edit] Notes
This form of change-detection is often more efficient than simple polling or pure spinlocks.
