/*****************************************************************************
 * 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 {

 *        ULONG (*fnQueryInterface)(IDirect3D* me);

 *        HRESULT (*fnFindDevice)(IDirect3D* me, LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b);
 *    }; 
 *
 *    #ifdef ICOM_CINTERFACE
 *    // *** IUnknown methods *** //
 *    #define IDirect3D_QueryInterface(p,a,b) (p)->lpVtbl->fnQueryInterface(p,a,b)
 *    #define IDirect3D_AddRef(p)             (p)->lpVtbl->fnAddRef(p)

 *    #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 (*fnInitialize)(IDirect3D* me, REFIID a);
 *        public: inline HRESULT Initialize(REFIID a) { return ((IDirect3D*)t.lpVtbl)->fnInitialize(this,a); };
 *        private: HRESULT (*fnEnumDevices)(IDirect3D* me, LPD3DENUMDEVICESCALLBACK a, LPVOID b);
 *        public: inline HRESULT EnumDevices(LPD3DENUMDEVICESCALLBACK a, LPVOID b)
 *            { return ((IDirect3D*)t.lpVtbl)->fnEnumDevices(this,a,b); };
 *        private: HRESULT (*fnCreateLight)(IDirect3D* me, LPDIRECT3DLIGHT* a, IUnknown* b);
 *        public: inline HRESULT CreateLight(LPDIRECT3DLIGHT* a, IUnknown* b)
 *            { return ((IDirect3D*)t.lpVtbl)->fnCreateLight(this,a,b); };
 *        private: HRESULT (*fnCreateMaterial)(IDirect3D* me, LPDIRECT3DMATERIAL* a, IUnknown* b);
 *        public: inline HRESULT CreateMaterial(LPDIRECT3DMATERIAL* a, IUnknown* b)
 *            { return ((IDirect3D*)t.lpVtbl)->fnCreateMaterial(this,a,b); };
 *        private: HRESULT (*fnCreateViewport)(IDirect3D* me, LPDIRECT3DVIEWPORT* a, IUnknown* b);
 *        public: inline HRESULT CreateViewport(LPDIRECT3DVIEWPORT* a, IUnknown* b)
 *            { return ((IDirect3D*)t.lpVtbl)->fnCreateViewport(this,a,b); };
 *        private:  HRESULT (*fnFindDevice)(IDirect3D* me, LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b);
 *        public: inline HRESULT FindDevice(LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b)
 *            { return ((IDirect3D*)t.lpVtbl)->fnFindDevice(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.fnQueryInterface, 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_fnQueryInterface(IDirect3D* me)
 *    {
 *        ICOM_THIS(IDirect3D,me);
 *        // ...
 *    }
 *
 *    // ...
 *
 *    static ICOM_VTABLE(IDirect3D) d3dvt = {
 *        ICOM_MSVTABLE_COMPAT_DummyRTTIVALUE
 *        IDirect3D_fnQueryInterface,
 *        IDirect3D_fnAdd,
 *        IDirect3D_fnAdd2,
 *        IDirect3D_fnInitialize,
 *        IDirect3D_fnSetWidth
 *    };
 *
 * 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.
