>Converts data given in physical units (data) into sample values
(lsampl_t, between 0 and maxdata). The parameter rng
represents the conversion information to use, and the parameter
maxdata represents the maximum possible data value for the
channel that the data will be written to.</P
><P
>Conversion is not affected by out-of-range behavior. Out-of-range
data parameters are silently truncated to the range 0 to maxdata.</P
