The extended return exists for build-in-place results of limited types. There's
really no reason to use it for other types.
function Gettexgen (Coord : in Texture_Coordiate_Type;
Pname : in Texture_Coordinate_Generation)
return Double_Vector_Type is
Result : aliased Double_Vector_Type (1 .. Get_Elements (Pname) );
begin -- Gettexgen
Glgettexgendv (Coord => Convert (Coord),
Pname => Convert (Pname),
Params => Result'Unchecked_Access);
return Result;
end Gettexgen;
