comedi_cmd.data

We are trying to write real-time kernel code that uses a comedi command to sample data asynchronously.  The documentation leads us to believe that the data field in the comedi_cmd struct should be updated with the data that is read in after each scan, but I have not observed that these values change at all (we are feeding a sine wave into the DAQ).  We are checking these values with a callback after every scan.

How does comedi use the comedi_cmd.data field?
