#ifdef __cplusplus } #endif /***************************************************************************** * Macros to define a COM interface */ /* * The goal of the following set of definitions is to provide a way to use the same * header file definitions to provide both a C interface and a C++ object oriented * interface to COM interfaces. The type of interface is selected automatically * depending on the language but it is always possible to get the C interface in C++ * by defining CINTERFACE. * * It is based on the following assumptions: * - all COM interfaces derive from IUnknown, this should not be a problem. * - the header file only defines the interface, the actual fields are defined * separately in the C file implementing the interface. * * The natural approach to this problem would be to make sure we get a C++ class and * virtual methods in C++ and a structure with a table of pointer to functions in C. * Unfortunately the layout of the virtual table is compiler specific, the layout of * g++ virtual tables is not the same as that of an egcs virtual table which is not the * same as that generated by Visual C+. There are workarounds to make the virtual tables * compatible via padding but unfortunately the one which is imposed to the WINE emulator * by the Windows binaries, i.e. the Visual C++ one, is the most compact of all. * * So the solution I finally adopted does not use virtual tables. Instead I use inline * non virtual methods that dereference the method pointer themselves and perform the call. * * Let's take Direct3D as an example: * * #define ICOM_INTERFACE IDirect3D * #define IDirect3D_METHODS \ * ICOM_METHOD1(HRESULT,Initialize, REFIID,) \ * ICOM_METHOD2(HRESULT,EnumDevices, LPD3DENUMDEVICESCALLBACK,, LPVOID,) \ * ICOM_METHOD2(HRESULT,CreateLight, LPDIRECT3DLIGHT*,, IUnknown*,) \ * ICOM_METHOD2(HRESULT,CreateMaterial,LPDIRECT3DMATERIAL*,, IUnknown*,) \ * ICOM_METHOD2(HRESULT,CreateViewport,LPDIRECT3DVIEWPORT*,, IUnknown*,) \ * ICOM_METHOD2(HRESULT,FindDevice, LPD3DFINDDEVICESEARCH,, LPD3DFINDDEVICERESULT,) * #define IDirect3D_IMETHODS \ * IUnknown_IMETHODS \ * IDirect3D_METHODS * ICOM_DEFINE(IDirect3D,IUnknown) * #undef ICOM_INTERFACE * * #ifdef ICOM_CINTERFACE * // *** IUnknown methods *** // * #define IDirect3D_QueryInterface(p,a,b) ICOM_CALL2(QueryInterface,p,a,b) * #define IDirect3D_AddRef(p) ICOM_CALL (AddRef,p) * #define IDirect3D_Release(p) ICOM_CALL (Release,p) * // *** IDirect3D methods *** // * #define IDirect3D_Initialize(p,a) ICOM_CALL1(Initialize,p,a) * #define IDirect3D_EnumDevices(p,a,b) ICOM_CALL2(EnumDevice,p,a,b) * #define IDirect3D_CreateLight(p,a,b) ICOM_CALL2(CreateLight,p,a,b) * #define IDirect3D_CreateMaterial(p,a,b) ICOM_CALL2(CreateMaterial,p,a,b) * #define IDirect3D_CreateViewport(p,a,b) ICOM_CALL2(CreateViewport,p,a,b) * #define IDirect3D_FindDevice(p,a,b) ICOM_CALL2(FindDevice,p,a,b) * #endif * * Comments: * - The ICOM_INTERFACE macro is used in the ICOM_METHOD macros to define the type of the 'this' * pointer. Defining this macro here saves us the trouble of having to repeat the interface * name everywhere. Note however that because of the way macros work, a macro like ICOM_METHOD1 * cannot use 'ICOM_INTERFACE##_VTABLE' because this would give 'ICOM_INTERFACE_VTABLE' and not * 'IDirect3D_VTABLE'. * - ICOM_METHODS defines the methods specific to this interface. It is then aggregated with the * inherited methods to form ICOM_IMETHODS. * - ICOM_IMETHODS defines the list of methods that are inheritable from this interface. It must * be written manually (rather than using a macro to generate the equivalent code) to avoid * macro recursion (which compilers don't like). * - The ICOM_DEFINE finally declares all the structures necessary for the interface. We have to * explicitly use the interface name for macro expansion reasons again. * Inherited methods are inherited in C by using the IDirect3D_METHODS macro and the parent's * Xxx_IMETHODS macro. In C++ we need only use the IDirect3D_METHODS since method inheritance * is taken care of by the language. * - In C++ the ICOM_METHOD macros generate a function prototype and a call to a function pointer * method. This means using once 't1 p1, t2 p2, ...' and once 'p1, p2' without the types. The * only way I found to handle this is to have one ICOM_METHOD macro per number of parameters and * to have it take only the type information (with const if necessary) as parameters. * The 'undef ICOM_INTERFACE' is here to remind you that using ICOM_INTERFACE in the following * macros will not work. This time it's because the ICOM_CALL macro expansion is done only once * the 'IDirect3D_Xxx' macro is expanded. And by that time ICOM_INTERFACE will be long gone * anyway. * - You may have noticed the double commas after each parameter type. This allows you to put the * name of that parameter which I think is good for documentation. It is not required and since * I did not know what to put there for this example (I could only find doc about IDirect3D2), * I left them blank. * - Finally the set of 'IDirect3D_Xxx' macros is a standard set of macros defined to ease access * to the interface methods in C. Unfortunately I don't see any way to avoid having to duplicate * the inherited method definitions there. This time I could have used a trick to use only one * macro whatever the number of parameters but I prefered to have it work the same way as above. * - You probably have noticed that we don't define the fields we need to actually implement this * interface: reference count, pointer to other resources and miscellaneous fields. That's * because these interfaces are just that: interfaces. They may be implemented more than once, in * different contexts and sometimes not even in Wine. Thus it would not make sense to impose * that the interface contains some specific fields. * * * In C this gives: * typedef struct IDirect3DVtbl IDirect3DVtbl; * struct IDirect3D { * IDirect3DVtbl* lpVtbl; * }; * struct IDirect3DVtbl { * HRESULT (*QueryInterface)(IDirect3D* me, REFIID riid, LPVOID* ppvObj); * ULONG (*QueryInterface)(IDirect3D* me); * ULONG (*QueryInterface)(IDirect3D* me); * HRESULT (*Initialize)(IDirect3D* me, REFIID a); * HRESULT (*EnumDevices)(IDirect3D* me, LPD3DENUMDEVICESCALLBACK a, LPVOID b); * HRESULT (*CreateLight)(IDirect3D* me, LPDIRECT3DLIGHT* a, IUnknown* b); * HRESULT (*CreateMaterial)(IDirect3D* me, LPDIRECT3DMATERIAL* a, IUnknown* b); * HRESULT (*CreateViewport)(IDirect3D* me, LPDIRECT3DVIEWPORT* a, IUnknown* b); * HRESULT (*FindDevice)(IDirect3D* me, LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b); * }; * * #ifdef ICOM_CINTERFACE * // *** IUnknown methods *** // * #define IDirect3D_QueryInterface(p,a,b) (p)->lpVtbl->QueryInterface(p,a,b) * #define IDirect3D_AddRef(p) (p)->lpVtbl->AddRef(p) * #define IDirect3D_Release(p) (p)->lpVtbl->Release(p) * // *** IDirect3D methods *** // * #define IDirect3D_Initialize(p,a) (p)->lpVtbl->Initialize(p,a) * #define IDirect3D_EnumDevices(p,a,b) (p)->lpVtbl->EnumDevice(p,a,b) * #define IDirect3D_CreateLight(p,a,b) (p)->lpVtbl->CreateLight(p,a,b) * #define IDirect3D_CreateMaterial(p,a,b) (p)->lpVtbl->CreateMaterial(p,a,b) * #define IDirect3D_CreateViewport(p,a,b) (p)->lpVtbl->CreateViewport(p,a,b) * #define IDirect3D_FindDevice(p,a,b) (p)->lpVtbl->FindDevice(p,a,b) * #endif * * Comments: * - IDirect3D only contains a pointer to the IDirect3D virtual/jump table. This is the only thing * the user needs to know to use the interface. Of course the structure we will define to * implement this interface will have more fields but the first one will match this pointer. * - The code generated by ICOM_DEFINE defines both the structure representing the interface and * the structure for the jump table. ICOM_DEFINE uses the parent's Xxx_IMETHODS macro to * automatically repeat the prototypes of all the inherited methods and then uses IDirect3D_METHODS * to define the IDirect3D methods. * - Each method is declared as a pointer to function field in the jump table. The implementation * will fill this jump table with appropriate values, probably using a static variable, and * initialize the lpVtbl field to point to this variable. * - The IDirect3D_Xxx macros then just derefence the lpVtbl pointer and use the function pointer * corresponding to the macro name. This emulates the behavior of a virtual table and should be * just as fast. * - This C code should be quite compatible with the Windows headers both for code that uses COM * interfaces and for code implementing a COM interface. * * * And in C++ (with gcc's g++): * * typedef struct IDirect3D: public IUnknown { * private: HRESULT (*Initialize)(IDirect3D* me, REFIID a); * public: inline HRESULT Initialize(REFIID a) { return ((IDirect3D*)t.lpVtbl)->Initialize(this,a); }; * private: HRESULT (*EnumDevices)(IDirect3D* me, LPD3DENUMDEVICESCALLBACK a, LPVOID b); * public: inline HRESULT EnumDevices(LPD3DENUMDEVICESCALLBACK a, LPVOID b) * { return ((IDirect3D*)t.lpVtbl)->EnumDevices(this,a,b); }; * private: HRESULT (*freateLight)(IDirect3D* me, LPDIRECT3DLIGHT* a, IUnknown* b); * public: inline HRESULT CreateLight(LPDIRECT3DLIGHT* a, IUnknown* b) * { return ((IDirect3D*)t.lpVtbl)->CreateLight(this,a,b); }; * private: HRESULT (*CreateMaterial)(IDirect3D* me, LPDIRECT3DMATERIAL* a, IUnknown* b); * public: inline HRESULT CreateMaterial(LPDIRECT3DMATERIAL* a, IUnknown* b) * { return ((IDirect3D*)t.lpVtbl)->CreateMaterial(this,a,b); }; * private: HRESULT (*CreateViewport)(IDirect3D* me, LPDIRECT3DVIEWPORT* a, IUnknown* b); * public: inline HRESULT CreateViewport(LPDIRECT3DVIEWPORT* a, IUnknown* b) * { return ((IDirect3D*)t.lpVtbl)->CreateViewport(this,a,b); }; * private: HRESULT (*FindDevice)(IDirect3D* me, LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b); * public: inline HRESULT FindDevice(LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b) * { return ((IDirect3D*)t.lpVtbl)->FindDevice(this,a,b); }; * }; * * Comments: * - In C++ IDirect3D does double duty as both the virtual/jump table and as the interface * definition. The reason for this is to avoid having to duplicate the mehod definitions: once * to have the function pointers in the jump table and once to have the methods in the interface * class. Here one macro can generate both. This means though that the first pointer, t.lpVtbl * defined in IUnknown, must be interpreted as the jump table pointer if we interpret the * structure as the the interface class, and as the function pointer to the QueryInterface * method, t.QueryInterface, if we interpret the structure as the jump table. Fortunately this * gymnastic is entirely taken care of in the header of IUnknown. * - Of course in C++ we use inheritance so that we don't have to duplicate the method definitions. * - Since IDirect3D does double duty, each ICOM_METHOD macro defines both a function pointer and * a non-vritual inline method which dereferences it and calls it. This way this method behaves * just like a virtual method but does not create a true C++ virtual table which would break the * structure layout. If you look at the implementation of these methods you'll notice that they * would not work for void functions. We have to return something and fortunately this seems to * be what all the COM methods do (otherwise we would need another set of macros). * - Note how the ICOM_METHOD generates both function prototypes mixing types and formal parameter * names and the method invocation using only the formal parameter name. This is the reason why * we need different macros to handle different numbers of parameters. * - Finally there is no IDirect3D_Xxx macro. These are not needed in C++ unless the CINTERFACE * macro is defined in which case we would not be here. * - This C++ code works well for code that just uses COM interfaces. But it will not work with * C++ code implement a COM interface. That's because such code assumes the interface methods * are declared as virtual C++ methods which is not the case here. * * * Implementing a COM interface. * * This continues the above example. This example assumes that the implementation is in C. * * typedef struct _IDirect3D { * void* lpVtbl; * // ... * * } _IDirect3D; * * static ICOM_VTABLE(IDirect3D) d3dvt; * * // implement the IDirect3D methods here * * int IDirect3D_QueryInterface(IDirect3D* me) * { * ICOM_THIS(IDirect3D,me); * // ... * } * * // ... * * static ICOM_VTABLE(IDirect3D) d3dvt = { * ICOM_MSVTABLE_COMPAT_DummyRTTIVALUE * IDirect3D_QueryInterface, * IDirect3D_Add, * IDirect3D_Add2, * IDirect3D_Initialize, * IDirect3D_SetWidth * }; * * Comments: * - We first define what the interface really contains. This is th e_IDirect3D structure. The * first field must of course be the virtual table pointer. Everything else is free. * - Then we predeclare our static virtual table variable, we will need its address in some * methods to initialize the virtual table pointer of the returned interface objects. * - Then we implement the interface methods. To match what has been declared in the header file * they must take a pointer to a IDirect3D structure and we must cast it to an _IDirect3D so that * we can manipulate the fields. This is performed by the ICOM_THIS macro. * - Finally we initialize the virtual table. */ #if !defined(__cplusplus) || defined(CINTERFACE) #define ICOM_CINTERFACE 1 #endif #ifndef ICOM_CINTERFACE /* C++ interface */ #define ICOM_METHOD(ret,xfn) \ public: virtual ret CALLBACK (xfn)(void) = 0;
