  26  * Macros to define a COM interface
  27  */
  28 /*
  29  * The goal of the following set of definitions is to provide a way to use the same
  30  * header file definitions to provide both a C interface and a C++ object oriented
  31  * interface to COM interfaces. The type of interface is selected automatically
  32  * depending on the language but it is always possible to get the C interface in C++
  33  * by defining CINTERFACE.
  34  *
  35  * It is based on the following assumptions:
  36  *  - all COM interfaces derive from IUnknown, this should not be a problem.
  37  *  - the header file only defines the interface, the actual fields are defined
  38  *    separately in the C file implementing the interface.
  39  *
  40  * The natural approach to this problem would be to make sure we get a C++ class and
  41  * virtual methods in C++ and a structure with a table of pointer to functions in C.
  42  * Unfortunately the layout of the virtual table is compiler specific, the layout of
  43  * g++ virtual tables is not the same as that of an egcs virtual table which is not the
  44  * same as that generated by Visual C+. There are workarounds to make the virtual tables
  45  * compatible via padding but unfortunately the one which is imposed to the WINE emulator
  46  * by the Windows binaries, i.e. the Visual C++ one, is the most compact of all.
  47  *
  48  * So the solution I finally adopted does not use virtual tables. Instead I use inline
  49  * non virtual methods that dereference the method pointer themselves and perform the call.
  50  *
  51  * Let's take Direct3D as an example:
  52  *
  53  *    #define INTERFACE IDirect3D
  54  *    #define IDirect3D_METHODS \
  55  *        IUnknown_METHODS \
  56  *        STDMETHOD(Initialize)(THIS_ REFIID) PURE; \
  57  *        STDMETHOD(EnumDevices)(THIS_ LPD3DENUMDEVICESCALLBACK, LPVOID) PURE; \
  58  *        STDMETHOD(CreateLight)(THIS_ LPDIRECT3DLIGHT*, IUnknown*) PURE; \
  59  *        STDMETHOD(CreateMaterial)(THIS_ LPDIRECT3DMATERIAL*, IUnknown*) PURE; \
  60  *        STDMETHOD(CreateViewport)(THIS_ LPDIRECT3DVIEWPORT*, IUnknown*) PURE; \
  61  *        STDMETHOD(FindDevice)(THIS_ LPD3DFINDDEVICESEARCH, LPD3DFINDDEVICERESULT) PURE;
  62  *    DECLARE_INTERFACE_(IDirect3D,IUnknown) { IDirect3D_METHODS };
  63  *    #undef INTERFACE
  64  *
  65  *    #ifdef COBJMACROS
  66  *    // *** IUnknown methods *** //
  67  *    #define IDirect3D_QueryInterface(p,a,b) (p)->lpVtbl->QueryInterface(p,a,b)
  68  *    #define IDirect3D_AddRef(p)             (p)->lpVtbl->AddRef(p)
  69  *    #define IDirect3D_Release(p)            (p)->lpVtbl->Release(p)
  70  *    // *** IDirect3D methods *** //
  71  *    #define IDirect3D_Initialize(p,a)       (p)->lpVtbl->Initialize(p,a)
  72  *    #define IDirect3D_EnumDevices(p,a,b)    (p)->lpVtbl->EnumDevice(p,a,b)
  73  *    #define IDirect3D_CreateLight(p,a,b)    (p)->lpVtbl->CreateLight(p,a,b)
  74  *    #define IDirect3D_CreateMaterial(p,a,b) (p)->lpVtbl->CreateMaterial(p,a,b)
  75  *    #define IDirect3D_CreateViewport(p,a,b) (p)->lpVtbl->CreateViewport(p,a,b)
  76  *    #define IDirect3D_FindDevice(p,a,b)     (p)->lpVtbl->FindDevice(p,a,b)
  77  *    #endif
  78  *
  79  * Comments:
  80  *  - The INTERFACE macro is used in the STDMETHOD macros to define the type of the 'this'
  81  *    pointer. Defining this macro here saves us the trouble of having to repeat the interface
  82  *    name everywhere. Note however that because of the way macros work, a macro like STDMETHOD
  83  *    cannot use 'INTERFACE##_VTABLE' because this would give 'INTERFACE_VTABLE' and not
  84  *    'IDirect3D_VTABLE'.
  85  *  - ICOM_METHODS defines the list of methods that are inheritable from this interface. It must
  86  *    be written manually (rather than using a macro to generate the equivalent code) to avoid
  87  *    macro recursion (which compilers don't like). It must start with the METHODS definition
  88  *    of the parent interface so that method inheritance works properly.
  89  *  - The DECLARE_INTERFACE finally declares all the structures necessary for the interface. We have
  90  *    to explicitly use the interface name for macro expansion reasons again.
  91  *  - The 'undef INTERFACE' is here to remind you that using INTERFACE in the following macros
  92  *    will not work.
  93  *  - Finally the set of 'IDirect3D_Xxx' macros is a standard set of macros defined to ease access
  94  *    to the interface methods in C. Unfortunately I don't see any way to avoid having to duplicate
  95  *    the inherited method definitions there. This time I could have used a trick to use only one
  96  *    macro whatever the number of parameters but I prefered to have it work the same way as above.
  97  *  - You probably have noticed that we don't define the fields we need to actually implement this
  98  *    interface: reference count, pointer to other resources and miscellaneous fields. That's
  99  *    because these interfaces are just that: interfaces. They may be implemented more than once, in
 100  *    different contexts and sometimes not even in Wine. Thus it would not make sense to impose
 101  *    that the interface contains some specific fields.
 102  *
 103  *
 104  * In C this gives:
 105  *    typedef struct IDirect3DVtbl IDirect3DVtbl;
 106  *    struct IDirect3D {
 107  *        IDirect3DVtbl* lpVtbl;
 108  *    };
 109  *    struct IDirect3DVtbl {
 110  *        HRESULT (*QueryInterface)(IDirect3D* me, REFIID riid, LPVOID* ppvObj);
 111  *        ULONG (*QueryInterface)(IDirect3D* me);
 112  *        ULONG (*QueryInterface)(IDirect3D* me);
 113  *        HRESULT (*Initialize)(IDirect3D* me, REFIID a);
 114  *        HRESULT (*EnumDevices)(IDirect3D* me, LPD3DENUMDEVICESCALLBACK a, LPVOID b);
 115  *        HRESULT (*CreateLight)(IDirect3D* me, LPDIRECT3DLIGHT* a, IUnknown* b);
 116  *        HRESULT (*CreateMaterial)(IDirect3D* me, LPDIRECT3DMATERIAL* a, IUnknown* b);
 117  *        HRESULT (*CreateViewport)(IDirect3D* me, LPDIRECT3DVIEWPORT* a, IUnknown* b);
 118  *        HRESULT (*FindDevice)(IDirect3D* me, LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b);
 119  *    };

 133  *    #endif
 134  *
 135  * Comments:
 136  *  - IDirect3D only contains a pointer to the IDirect3D virtual/jump table. This is the only thing
 137  *    the user needs to know to use the interface. Of course the structure we will define to
 138  *    implement this interface will have more fields but the first one will match this pointer.
 139  *  - The code generated by DECLARE_INTERFACE defines both the structure representing the interface and
 140  *    the structure for the jump table. DECLARE_INTERFACE uses the parent's Xxx_METHODS macro to
 141  *    automatically repeat the prototypes of all the inherited methods and then uses IDirect3D_METHODS
 142  *    to define the IDirect3D methods.
 143  *  - Each method is declared as a pointer to function field in the jump table. The implementation
 144  *    will fill this jump table with appropriate values, probably using a static variable, and
 145  *    initialize the lpVtbl field to point to this variable.
 146  *  - The IDirect3D_Xxx macros then just derefence the lpVtbl pointer and use the function pointer
 147  *    corresponding to the macro name. This emulates the behavior of a virtual table and should be
 148  *    just as fast.
 149  *  - This C code should be quite compatible with the Windows headers both for code that uses COM
 150  *    interfaces and for code implementing a COM interface.
 151  *
 152  *
 153  * And in C++ (with gcc's g++):
 154  *
 155  *    typedef struct IDirect3D: public IUnknown {
 156  *        virtual HRESULT Initialize(REFIID a) = 0;
 157  *        virtual HRESULT EnumDevices(LPD3DENUMDEVICESCALLBACK a, LPVOID b) = 0;
 158  *        virtual HRESULT CreateLight(LPDIRECT3DLIGHT* a, IUnknown* b) = 0;
 159  *        virtual HRESULT CreateMaterial(LPDIRECT3DMATERIAL* a, IUnknown* b) = 0;
 160  *        virtual HRESULT CreateViewport(LPDIRECT3DVIEWPORT* a, IUnknown* b) = 0;
 161  *        virtual HRESULT FindDevice(LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b) = 0;
 162  *    };
 163  *
 164  * Comments:
 165  *  - Of course in C++ we use inheritance so that we don't have to duplicate the method definitions.
 166  *  - Finally there is no IDirect3D_Xxx macro. These are not needed in C++ unless the CINTERFACE
 167  *    macro is defined in which case we would not be here.
 168  *
 169  *
 170  * Implementing a COM interface.
 171  *
 172  * This continues the above example. This example assumes that the implementation is in C.
 173  *
 174  *    typedef struct _IDirect3D {
 175  *        void* lpVtbl;
 176  *        // ...
 177  *
 178  *    } _IDirect3D;
 179  *
 180  *    static IDirect3DVtbl d3dvt;
 181  *
 182  *    // implement the IDirect3D methods here
 183  *
 184  *    int IDirect3D_QueryInterface(IDirect3D* me)
 185  *    {
 186  *        ICOM_THIS(IDirect3D,me);
 187  *        // ...
 188  *    }
 189  *
 190  *    // ...
 191  *
 192  *    static IDirect3DVtbl d3dvt = {
 193  *        IDirect3D_QueryInterface,
 194  *        IDirect3D_Add,
 195  *        IDirect3D_Add2,
 196  *        IDirect3D_Initialize,
 197  *        IDirect3D_SetWidth
 198  *    };
 199  *
 200  * Comments:
 201  *  - We first define what the interface really contains. This is th e_IDirect3D structure. The
 202  *    first field must of course be the virtual table pointer. Everything else is free.
 203  *  - Then we predeclare our static virtual table variable, we will need its address in some
 204  *    methods to initialize the virtual table pointer of the returned interface objects.
 205  *  - Then we implement the interface methods. To match what has been declared in the header file
 206  *    they must take a pointer to a IDirect3D structure and we must cast it to an _IDirect3D so that
 207  *    we can manipulate the fields. This is performed by the ICOM_THIS macro.
 208  *  - Finally we initialize the virtual table.
