As you might expect, ptr[range] is for range 'range',
which you provided to comedi_data_read() above. 'min' represents
the voltage corresponding to comedi_data_read() returning 0,
and 'max' represents comedi_data_read() returning 'maxdata',
(i.e., 4095 for 12 bit A/C converters, 65535 for 16 bit,
or, 1 for digital input -- more on this in a bit.) The
