Calling this function does not pass ownership of the VARDESC structure to ICreateTypeInfo. The instance member (oInst) of the VARDESC structure is ignored.
This attribute is set only when ICreateTypeInfo::LayOut is called. Also, the member identifier members within the VARDESC structures are ignored unless the TYPEKIND of the class is TKIND_DISPATCH.
Any HREFTYPE members in the VARDESC structure must have been produced by the same instance of ITypeInfo for which AddVarDesc is called.
AddVarDesc ignores the contents of the idldesc member of the ELEMDESC.
