Owning Palette: Notifier Operations Functions

Installed With: Base Package

Releases a reference to a notifier.

Details  Examples

	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.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally even if an error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use exception control to treat what is normally an error as no error or to treat a warning as an error. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	notifier name is the name of the notifier.
	last notification is the last uncancelled notification sent to the notifier. If no notification is available, the function returns the zero value for the element data type you wired in the Obtain Notifier function.This data type changes to match the subtype of notifier.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.

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.

Examples

Refer to the following VIs for examples of using the Release Notifier function:

• General Notifier Example VI: labview\examples\general\notifier.llb
• Wait for All Notifications Demo VI: labview\examples\general\WaitForAll.llb
