std::atomic_ref
 
(since C++20)
void notify_all() const noexcept;
void notify_all() const volatile noexcept;

Performs atomic notifying operations.

Unblocks all threads blocked in atomic waiting operations (i.e. wait()) on *this, if there are any; otherwise does nothing.

Return value

(none)

Notes

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