Destroy User Event (G Dataflow)

Last Modified: March 15, 2017

Releases a user event reference by destroying its associated user event refnum. Any Event Structures registered for this user event no longer receive the event.


user event

User event refnum created by a Create User Event node.


error in

Error conditions that occur before this node runs. Unlike most nodes, this node runs normally even if an error occurs before this node runs.

Default: no error


error out

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Where This Node Can Run:

Desktop OS: Windows

FPGA: This product does not support FPGA devices
