Release Semaphore Reference (G Dataflow)

Last Modified: March 15, 2017

Releases a reference to a semaphore.



A reference to a semaphore.


force destroy

A Boolean that specifies whether to destroy the semaphore. If False, the semaphore is destroyed only if no other references to the semaphore exist. If True, all references to the semaphore are released and the semaphore is destroyed.


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


semaphore name

The name of the semaphore.


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
