Returns current status information of a semaphore.
The name of the semaphore.
A reference to a semaphore.
Error conditions that occur before this node runs.
The node responds to this input 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.
Default: No error
The maximum number of tasks that can acquire the semaphore at a time.
Same value as the input semaphore.
The number of tasks that can acquire the semaphore at the current time. This number is always less than or equal to the size.
The number of Acquire Semaphore nodes currently waiting to acquire the semaphore.
Error information.
The node produces this output according to standard error behavior.
