Owning Palette: Semaphore VIs
Requires: Base Development System
Releases a reference to a semaphore.
|semaphore is a reference to a semaphore.|
|force destroy? specifies whether to destroy the semaphore. If FALSE (default), LabVIEW destroys the semaphore only if no other references to the semaphore exist. If TRUE, LabVIEW releases all references to the semaphore and destroys the semaphore.|
|error in describes error conditions that occur before this node runs. With the following exception, this input provides standard error in functionality.
This node runs normally even if an error occurred before this node runs.
|semaphore name is the name of the semaphore.|
|error out contains error information. This output provides standard error out functionality.|
All Acquire Semaphore VIs that are currently waiting on this reference to the semaphore time out immediately and return an error. This does not affect any Acquire Semaphore VIs that are waiting on a different reference to the same semaphore. However, if force destroy? is TRUE, all Acquire Semaphore VIs, including those that are waiting on a different reference to the semaphore, time out immediately and return an error.
Refer to the Simple Semaphore VI in the labview\examples\Synchronization\Semaphore directory for an example of using the Release Semaphore Reference VI.
