/****** 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);
|
||
|
|
