// comdecl.h: Macros to facilitate COM interface and GUID declarations.

#ifndef _COMDECL_H_

#include <basetyps.h>   // For standard COM interface macros 
 
// The DEFINE_CLSID() and DEFINE_IID() macros defined below allow COM GUIDs to 
// be declared and defined in such a way that clients can obtain the GUIDs using 
// 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++.
