Details  

notifier is a reference to a notifier. Use the Obtain Notifier function to obtain a notifier reference.
force destroy? indicates whether to destroy the notifier. If FALSE (default) and you want to destroy the notifier, call the Release Notifier function a number of times equal to the number of times you obtained a reference to the notifier or stop all VIs using the notifier reference. If TRUE, the function destroys the notifier and you do not have to call the function multiple times or stop all VIs using the notifier reference.

This node runs normally even if an error occurred before this node runs.

Release Notifier Details

You can use the Obtain Notifier function to obtain a reference to the same notifier with the same name multiple times. To destroy a notifier, call the Release Notifier function a number of times equal to the number of times you obtained a reference to the notifier or stop all VIs using the notifier reference.

If force destroy? is TRUE, this function releases all references to the notifier and destroys the notifier.

Any Wait on Notification or Wait on Notification from Multiple functions waiting on the notifier time out and return error code 1122.
