(1) | (since C++20) |
| template< class T > void atomic_notify_all( volatile std::atomic<T>* object ); |
(2) | (since C++20) |
Performs atomic notifying operations.
Unblocks all threads blocked in atomic waiting operations (i.e. std::atomic_wait(), std::atomic_wait_explicit(), or std::atomic::wait()) on *object, if there are any; otherwise does nothing.
Equivalent to object->notify_all().
Parameters
| object | - | pointer to the atomic object to notify |
Return value

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