       Used to prepare an analog input for a subsequent call to comedi_data_read. It is not necessary to use
       this function, but it can be useful for eliminating inaccuracies caused by insufficient settling times
       when switching the channel or gain on an analog input. This function sets an analog input to the channel,
       range, and aref specified but does not perform an actual analog to digital conversion.

       Alternatively, one can simply use comedi_data_read_delayed, which sets up the input, pauses to allow
       settling, then performs a conversion.
