Converts data
given in physical units into Comedi's
integer sample values
(lsampl_t, between 0 and maxdata). The conversion_polynomial
parameter is obtained from either comedi_get_hardcal_converter()
or comedi_get_softcal_converter(). The result will be rounded
using the C library's current rounding direction.
No range checking of the input
data
is performed. It is up to you to insure
your data is within the limits of the output range you are using.
This function is intended to supplant comedi_from_phys(), and was introduced in order to support software calibrations.
