Ring and Sequence Functions
Use the ring and sequence functions to perform a multibuffered acquisition that stops after all buffers are filled (sequence) or continually loops through the buffers (ring).
To use the ring and sequence functions, you must first call imgRingSetup or imgSequenceSetup to configure the session and optionally start the acquisition process. If you do not start the acquisition using imgRingSetup or imgSequenceSetup, you must call imgSessionStartAcquisition to start the acquisition.
