Performs atomic notifying operations.
Unblocks all threads blocked in atomic waiting operations (i.e. std::atomic_flag_wait(), std::atomic_flag_wait_explicit(), or std::atomic_flag::wait()) on *object
Equivalent to object->notify_all().
Parameters
object | - | pointer to the atomic_flag object to notify
|
Return value
(none)
Notes
This form of change-detection is often more efficient than simple polling or pure spinlocks.
