/****** 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);
