Parameters

numPending: Type: System Int32
The number of acquisitions in the pending state. This is the number of acquisitions requested by StartAcquire for which acquisition has not started. To achieve frame rate acquisition in manual trigger mode, the FIFO must always have one or more pending acquisitions.

numReady: Type: System Int32
The number of acquisition requests ready to be completed.

busy: Type: System Boolean
True if the oldest outstanding acquisition is waiting for a trigger signal or is acquiring an image. For master/slave acquisitions, it becomes true only after the master and all slaves are ready for acquisition.
