Comments

On return, the second parameter contains a pointer to a pointer to a type description that is referenced by this type description. A type description must have a reference to each type description that occurs as the type of any of its variables, function parameters, or function return types. For example, if the type of a data member is a record type, the typeinfo for that data member contains the hreftype of a referenced type description. To get a pointer to the type description, the reference is passed to GetRefTypeInfo.
