ListAPI.TryWaitForListIdle Method

public bool TryWaitForListIdle(
	out int? listID,
	int? timeout = null
)

Parameters

listID  Nullable<Int32>

Receives the Card-CommandList Identifier of the first list to become idle since the last time this function was called.

timeout  Nullable<Int32>  (Optional)

null (or omitted)	use the default timeout period specified by ClientAPI.Timeout
-1	wait indefinitely for the event
0	do not wait, simply check if an event has already been reported
> 0	timeout period in ms

Return Value

• Note that in case of a timeout this function will always return false.

  See WaitForListIdle(Nullable<Int32> , Nullable<Int32> ) if you wish to wait for a TimeoutException instead.

• Waiting can be interrupted by calling InterruptWaitForListIdle().

  Doing so will cause a ThreadInterruptedException.

• Like all methods which involve communication with the card, this method is not thread-safe.
• An idle event occurs when the card firmware has finished processing a list, and signals that the original list contents can now be altered again by the client.
• The event occurs regardless of how the list was called for execution: either explicitly ( ListAPI.Execute(Int32)), or as a sublist from another list.

  Note, however, that the event does not imply that all of the micro-vectors generated by the list have been output yet ( WaitForListDone(Nullable<Int32>, Nullable<Int32>)).
