// CAdviseSink::QueryInterface
//
// Purpose:
//
//      Used for interface negotiation
//
// Parameters:
//
//      REFIID riid         - The requested interface
//
//      LPVOID FAR* ppvObj  - Place to return the interface
//
// Return Value:

//      TestDebugOut           Windows API
//
// Comments:
//
//      This function simply delegates to the Object class, which is
//      aware of the supported interfaces.

// CAdviseSink::AddRef

// Purpose:
//
//      Increments the reference count on the CSimpleSite. Since CAdviseSink
//      is a nested class of CSimpleSite, we don't need a separate reference
//      count for CAdviseSink. We can just use the reference count of
//      CSimpleSite.

// Parameters:

//      None
//
// Return Value:
