Discussion This routine modifies the tracking information contained in the queue data structure to indicate that the queue is empty. If the queue is already empty, this has no effect. If there are characters in the queue, they will be discarded. Note that before any queue operations are performed, the queue data structure must be initialized. See the discussion of OpenQueue() for more details. Example Dim inQueue(1 to 40) as Byte Call OpenQueue(inQueue, SizeOf(inQueue)) Call PutQueueStr(inQueue, "Hello") Call ClearQueue(inQueue) After the call to ClearQueue() the queue will no longer contain the characters that were added. Compatibility BasicX allows any type for the first parameter. The ZBasic implementation requires that it be an array of Byte.
