Holder class. 
Non-descriptor parameters in API methods will be copied into a 
descriptor and held in a descriptor array iPtrArray. 
This class type also stores copies of API parameters that are passed in by value as opposed
to by reference. This keeps the size of the R-classes constant as the API evolves, thus
maintaining Binary Compatibility (BC).
