Description

       Similar to comedi_data_read except it will wait for the specified number of nanoseconds between setting
       the input channel and taking a sample. For analog inputs, most boards have a single analog to digital
       converter which is multiplexed to be able to read multiple channels. If the input is not allowed to
       settle after the multiplexer switches channels, the reading will be inaccurate. This function is useful
       for allowing a multiplexed analog input to settle when switching channels.

       Although the settling time is specified in nanoseconds, the actual settling time will be rounded up to
       the nearest microsecond.
