11 lsampl_t comedi_from_physical (double data, const comedi_polynomial_t
12 *conversion_polynomial);
13
15 Converts data given in physical units into Comedi's integer sample val‐
16 ues (lsampl_t, between 0 and maxdata). The conversion_polynomial
17 parameter is obtained from either comedi_get_hardcal_converter() or
18 comedi_get_softcal_converter(). The result will be rounded using the C
19 library's current rounding direction. No range checking of the input
20 data is performed. It is up to you to insure your data is within the
21 limits of the output range you are using.

23 This function is intended to supplant comedi_from_phys(), and was
24 introduced in order to support software calibrations.
25
27 Comedi sample value corresponding to input physical value.
