/****** Interface Declaration ***********************************************/

/*
 *      These are macros for declaring interfaces.  They exist so that
 *      a single definition of the interface is simulataneously a proper
 *      declaration of the interface structures (C++ abstract classes)
 *      for both C and C++.
 *
 *      DECLARE_INTERFACE(iface) is used to declare an interface that does
 *      not derive from a base interface.
 *      DECLARE_INTERFACE_(iface, baseiface) is used to declare an interface
 *      that does derive from a base interface.
 *
 *      By default if the source file has a .c extension the C version of
 *      the interface declaratations will be expanded; if it has a .cpp
 *      extension the C++ version will be expanded. if you want to force
 *      the C version expansion even though the source file has a .cpp
 *      extension, then define the macro "CINTERFACE".
 *      eg.     cl -DCINTERFACE file.cpp
 *
 *      Example Interface declaration:
 *
 *          #undef  INTERFACE
 *          #define INTERFACE   IClassFactory
 *
 *          DECLARE_INTERFACE_(IClassFactory, IUnknown)
 *          {
 *              // *** IUnknown methods ***
 *              STDMETHOD(QueryInterface) (THIS_
 *                                        REFIID riid,
 *                                        LPVOID FAR* ppvObj) PURE;
 *              STDMETHOD_(ULONG,AddRef) (THIS) PURE;
 *              STDMETHOD_(ULONG,Release) (THIS) PURE;
 *
 *              // *** IClassFactory methods ***
 *              STDMETHOD(CreateInstance) (THIS_
 *                                        LPUNKNOWN pUnkOuter,
 *                                        REFIID riid,
 *                                        LPVOID FAR* ppvObject) PURE;
 *          };
 *
 *      Example C++ expansion:
 *
 *          struct FAR IClassFactory : public IUnknown
 *          {
 *              virtual HRESULT STDMETHODCALLTYPE QueryInterface(
 *                                                  IID FAR& riid,
 *                                                  LPVOID FAR* ppvObj) = 0;
 *              virtual HRESULT STDMETHODCALLTYPE AddRef(void) = 0;
 *              virtual HRESULT STDMETHODCALLTYPE Release(void) = 0;
 *              virtual HRESULT STDMETHODCALLTYPE CreateInstance(
 *                                              LPUNKNOWN pUnkOuter,
 *                                              IID FAR& riid,
 *                                              LPVOID FAR* ppvObject) = 0;
 *          };
 *
 *          NOTE: Our documentation says '#define interface class' but we use
 *          'struct' instead of 'class' to keep a lot of 'public:' lines
 *          out of the interfaces.  The 'FAR' forces the 'this' pointers to
 *          be far, which is what we need.
 *
 *      Example C expansion:
 *
 *          typedef struct IClassFactory
 *          {
 *              const struct IClassFactoryVtbl FAR* lpVtbl;
 *          } IClassFactory;
 *
 *          typedef struct IClassFactoryVtbl IClassFactoryVtbl;
 *
 *          struct IClassFactoryVtbl
 *          {
 *              HRESULT (STDMETHODCALLTYPE * QueryInterface) (
 *                                                  IClassFactory FAR* This,
 *                                                  IID FAR* riid,
 *                                                  LPVOID FAR* ppvObj) ;
 *              HRESULT (STDMETHODCALLTYPE * AddRef) (IClassFactory FAR* This) ;
