Cancel Notification Details

If any Wait on Notification or Wait on Notification from Multiple functions received the message before the call to this function, those functions continue to execute. This function does not recall or reset any wait functions. After you cancel a notification, any subsequent wait functions wait until the notifier receives another message. Canceling a notification before the notifier has a message does not result in an error.
