std::atomic_flag::notify_one
| (since C++20) | ||
void notify_one() noexcept; |
||
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.
