// either the __uuidof() extension or the old-style CLSID_Foo / IID_IFoo names.

// If using the latter approach, the client can also choose whether to get the
|
|
// GUID definitions by defining the INITGUID preprocessor constant or by linking
|
|
// to a GUID library. This works in either C or C++.
