/*****************************************************************************
 * 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 INTERFACE IDirect3D
 *    DECLARE_INTERFACE_(IDirect3D,IUnknown)
 *    {
 *        // *** IUnknown methods *** //
 *        STDMETHOD_(HRESULT,QueryInterface)(THIS_ REFIID, void**) PURE;
 *        STDMETHOD_(ULONG,AddRef)(THIS) PURE;
 *        STDMETHOD_(ULONG,Release)(THIS) PURE;
 *        // *** IDirect3D methods *** //
 *        STDMETHOD(Initialize)(THIS_ REFIID) PURE;
 *        STDMETHOD(EnumDevices)(THIS_ LPD3DENUMDEVICESCALLBACK, LPVOID) PURE;
 *        STDMETHOD(CreateLight)(THIS_ LPDIRECT3DLIGHT *, IUnknown *) PURE;
 *        STDMETHOD(CreateMaterial)(THIS_ LPDIRECT3DMATERIAL *, IUnknown *) PURE;
 *        STDMETHOD(CreateViewport)(THIS_ LPDIRECT3DVIEWPORT *, IUnknown *) PURE;
 *        STDMETHOD(FindDevice)(THIS_ LPD3DFINDDEVICESEARCH, LPD3DFINDDEVICERESULT) PURE;
 *    };
 *    #undef INTERFACE
 *
 *    #ifdef COBJMACROS
 *    // *** 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:
 *  - The INTERFACE macro is used in the STDMETHOD 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 STDMETHOD
 *    cannot use 'INTERFACE##_VTABLE' because this would give 'INTERFACE_VTABLE' and not
 *    'IDirect3D_VTABLE'.
 *  - The DECLARE_INTERFACE declares all the structures necessary for the interface. We have to
 *    explicitly use the interface name for macro expansion reasons again. It 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). It must start with the methods definition of the parent interface so that
 *    method inheritance works properly.
 *  - The 'undef INTERFACE' is here to remind you that using INTERFACE in the following macros
 *    will not work.
 *  - 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 preferred 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 (*AddRef)(IDirect3D* me);
 *        ULONG (*Release)(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 COBJMACROS
 *    // *** 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 DECLARE_INTERFACE defines both the structure representing the interface and
 *    the structure for the jump table.
 *  - 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 {
 *        virtual HRESULT Initialize(REFIID a) = 0;
 *        virtual HRESULT EnumDevices(LPD3DENUMDEVICESCALLBACK a, LPVOID b) = 0;
 *        virtual HRESULT CreateLight(LPDIRECT3DLIGHT* a, IUnknown* b) = 0;
 *        virtual HRESULT CreateMaterial(LPDIRECT3DMATERIAL* a, IUnknown* b) = 0;
 *        virtual HRESULT CreateViewport(LPDIRECT3DVIEWPORT* a, IUnknown* b) = 0;
 *        virtual HRESULT FindDevice(LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b) = 0;
 *    };
 *
 * Comments:
 *  - Of course in C++ we use inheritance so that we don't have to duplicate the method definitions.
 *  - 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.
 *
 *
 * Implementing a COM interface.
 *
 * This continues the above example. This example assumes that the implementation is in C.
 *
 *    typedef struct IDirect3DImpl {
 *        void* lpVtbl;
 *        // ...
 *
 *    } IDirect3DImpl;
 *
 *    static IDirect3DVtbl d3dvt;
 *
 *    // implement the IDirect3D methods here
 *
 *    int IDirect3D_QueryInterface(IDirect3D* me)
 *    {
 *        IDirect3DImpl *This = (IDirect3DImpl *)me;
 *        // ...
 *    }
 *
 *    // ...
 *
 *    static IDirect3DVtbl d3dvt = {
 *        IDirect3D_QueryInterface,
 *        IDirect3D_Add,
 *        IDirect3D_Add2,
 *        IDirect3D_Initialize,
 *        IDirect3D_SetWidth
 *    };
 *
 * Comments:
 *  - We first define what the interface really contains. This is the IDirect3DImpl 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 an IDirect3D structure and we must cast it to an IDirect3DImpl so
 *    that we can manipulate the fields.
 *  - Finally we initialize the virtual table.
