Description

TryConvTypeToFamily looks up the conversion family identifier for the family of the specified conversion type or types. Conversion types are associated with a conversion family by the RegisterConversionType function when the conversion type is registered.

AType is the identifier for a registered conversion type (unit of measurement).

AFrom and ATo are two registered conversion types that are assumed to be in the same family.

AFamily returns the identifier of the conversion family.

TryConvTypeToFamily returns true if the family can be obtained (if AType is a registered conversion type or if AFrom and ATo are both registered in the same family), false otherwise.
