Comments

LayOut assigns VTBL offsets for virtual functions and instance offsets for per-instance data members, and creates the two typeinfos for dual interfaces. LayOut also assigns member ID numbers to the functions and variables unless the TYPEKIND of the class is TKIND_DISPATCH. LayOut should be called after all members of the type information are defined and before the type library is saved.

Use SaveAllChanges to save the type information after calling LayOut. Don't call other members of the ICreateTypeInfo interface after calling LayOut.

Note that different implementations of ICreateTypeInfo or other interfaces that create type information are free to assign any member ID numbers, provided that all members, including inherited members, have unique IDs.
