/****** 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) ; * HRESULT (STDMETHODCALLTYPE * Release) (IClassFactory FAR* This) ; * HRESULT (STDMETHODCALLTYPE * CreateInstance) ( * IClassFactory FAR* This, * LPUNKNOWN pUnkOuter, * IID FAR* riid, * LPVOID FAR* ppvObject); * HRESULT (STDMETHODCALLTYPE * LockServer) ( * IClassFactory FAR* This, * BOOL fLock); * }; */
