  99  * Macros to define a COM interface
 100  */
 101 /*
 102  * The goal of the following set of definitions is to provide a way to use the same
 103  * header file definitions to provide both a C interface and a C++ object oriented
 104  * interface to COM interfaces. The type of interface is selected automatically
 105  * depending on the language but it is always possible to get the C interface in C++
 106  * by defining CINTERFACE.
 107  *
 108  * It is based on the following assumptions:
 109  *  - all COM interfaces derive from IUnknown, this should not be a problem.
 110  *  - the header file only defines the interface, the actual fields are defined
 111  *    separately in the C file implementing the interface.
 112  *
 113  * The natural approach to this problem would be to make sure we get a C++ class and
 114  * virtual methods in C++ and a structure with a table of pointer to functions in C.
 115  * Unfortunately the layout of the virtual table is compiler specific, the layout of
 116  * g++ virtual tables is not the same as that of an egcs virtual table which is not the
 117  * same as that generated by Visual C+. There are workarounds to make the virtual tables
 118  * compatible via padding but unfortunately the one which is imposed to the WINE emulator
 119  * by the Windows binaries, i.e. the Visual C++ one, is the most compact of all.
 120  *
 121  * So the solution I finally adopted does not use virtual tables. Instead I use inline
 122  * non virtual methods that dereference the method pointer themselves and perform the call.
 123  *
 124  * Let's take Direct3D as an example:
 125  *
 126  *    #define ICOM_INTERFACE IDirect3D
 127  *    #define IDirect3D_METHODS \
 128  *        ICOM_METHOD1(HRESULT,Initialize,    REFIID,) \
 129  *        ICOM_METHOD2(HRESULT,EnumDevices,   LPD3DENUMDEVICESCALLBACK,, LPVOID,) \
 130  *        ICOM_METHOD2(HRESULT,CreateLight,   LPDIRECT3DLIGHT*,, IUnknown*,) \
 131  *        ICOM_METHOD2(HRESULT,CreateMaterial,LPDIRECT3DMATERIAL*,, IUnknown*,) \
 132  *        ICOM_METHOD2(HRESULT,CreateViewport,LPDIRECT3DVIEWPORT*,, IUnknown*,) \
 133  *        ICOM_METHOD2(HRESULT,FindDevice,    LPD3DFINDDEVICESEARCH,, LPD3DFINDDEVICERESULT,)
 134  *    #define IDirect3D_IMETHODS \
 135  *        IUnknown_IMETHODS \
 136  *        IDirect3D_METHODS
 137  *    ICOM_DEFINE(IDirect3D,IUnknown)
 138  *    #undef ICOM_INTERFACE
 139  *
 140  *    #ifdef ICOM_CINTERFACE
 141  *    // *** IUnknown methods *** //
 142  *    #define IDirect3D_QueryInterface(p,a,b) ICOM_CALL2(QueryInterface,p,a,b)
 143  *    #define IDirect3D_AddRef(p)             ICOM_CALL (AddRef,p)
 144  *    #define IDirect3D_Release(p)            ICOM_CALL (Release,p)
 145  *    // *** IDirect3D methods *** //
 146  *    #define IDirect3D_Initialize(p,a)       ICOM_CALL1(Initialize,p,a)
 147  *    #define IDirect3D_EnumDevices(p,a,b)    ICOM_CALL2(EnumDevice,p,a,b)

 152  *    #endif
 153  *
 154  * Comments:
 155  *  - The ICOM_INTERFACE macro is used in the ICOM_METHOD macros to define the type of the 'this'
 156  *    pointer. Defining this macro here saves us the trouble of having to repeat the interface
 157  *    name everywhere. Note however that because of the way macros work, a macro like ICOM_METHOD1
 158  *    cannot use 'ICOM_INTERFACE##_VTABLE' because this would give 'ICOM_INTERFACE_VTABLE' and not
 159  *    'IDirect3D_VTABLE'.
 160  *  - ICOM_METHODS defines the methods specific to this interface. It is then aggregated with the
 161  *    inherited methods to form ICOM_IMETHODS.
 162  *  - ICOM_IMETHODS defines the list of methods that are inheritable from this interface. It must
 163  *    be written manually (rather than using a macro to generate the equivalent code) to avoid
 164  *    macro recursion (which compilers don't like).
 165  *  - The ICOM_DEFINE finally declares all the structures necessary for the interface. We have to
 166  *    explicitly use the interface name for macro expansion reasons again.
 167  *    Inherited methods are inherited in C by using the IDirect3D_METHODS macro and the parent's
 168  *    Xxx_IMETHODS macro. In C++ we need only use the IDirect3D_METHODS since method inheritance
 169  *    is taken care of by the language.
 170  *  - In C++ the ICOM_METHOD macros generate a function prototype and a call to a function pointer
 171  *    method. This means using once 't1 p1, t2 p2, ...' and once 'p1, p2' without the types. The
 172  *    only way I found to handle this is to have one ICOM_METHOD macro per number of parameters and
 173  *    to have it take only the type information (with const if necessary) as parameters.
 174  *    The 'undef ICOM_INTERFACE' is here to remind you that using ICOM_INTERFACE in the following
 175  *    macros will not work. This time it's because the ICOM_CALL macro expansion is done only once
 176  *    the 'IDirect3D_Xxx' macro is expanded. And by that time ICOM_INTERFACE will be long gone
 177  *    anyway.
 178  *  - You may have noticed the double commas after each parameter type. This allows you to put the
 179  *    name of that parameter which I think is good for documentation. It is not required and since
 180  *    I did not know what to put there for this example (I could only find doc about IDirect3D2),
 181  *    I left them blank.
 182  *  - Finally the set of 'IDirect3D_Xxx' macros is a standard set of macros defined to ease access
 183  *    to the interface methods in C. Unfortunately I don't see any way to avoid having to duplicate
 184  *    the inherited method definitions there. This time I could have used a trick to use only one
 185  *    macro whatever the number of parameters but I prefered to have it work the same way as above.
 186  *  - You probably have noticed that we don't define the fields we need to actually implement this
 187  *    interface: reference count, pointer to other resources and miscellaneous fields. That's
 188  *    because these interfaces are just that: interfaces. They may be implemented more than once, in
 189  *    different contexts and sometimes not even in Wine. Thus it would not make sense to impose
 190  *    that the interface contains some specific fields.
 191  *

 222  *    #endif
 223  *
 224  * Comments:
 225  *  - IDirect3D only contains a pointer to the IDirect3D virtual/jump table. This is the only thing
 226  *    the user needs to know to use the interface. Of course the structure we will define to
 227  *    implement this interface will have more fields but the first one will match this pointer.
 228  *  - The code generated by ICOM_DEFINE defines both the structure representing the interface and
 229  *    the structure for the jump table. ICOM_DEFINE uses the parent's Xxx_IMETHODS macro to
 230  *    automatically repeat the prototypes of all the inherited methods and then uses IDirect3D_METHODS
 231  *    to define the IDirect3D methods.
 232  *  - Each method is declared as a pointer to function field in the jump table. The implementation
 233  *    will fill this jump table with appropriate values, probably using a static variable, and
 234  *    initialize the lpVtbl field to point to this variable.
 235  *  - The IDirect3D_Xxx macros then just derefence the lpVtbl pointer and use the function pointer
 236  *    corresponding to the macro name. This emulates the behavior of a virtual table and should be
 237  *    just as fast.
 238  *  - This C code should be quite compatible with the Windows headers both for code that uses COM
 239  *    interfaces and for code implementing a COM interface.
 240  *
 241  *
 242  * And in C++ (with gcc's g++):
 243  *
 244  *    typedef struct IDirect3D: public IUnknown {
 245  *        private: HRESULT (*fnInitialize)(IDirect3D* me, REFIID a);
 246  *        public: inline HRESULT Initialize(REFIID a) { return ((IDirect3D*)t.lpVtbl)->fnInitialize(this,a); };
 247  *        private: HRESULT (*fnEnumDevices)(IDirect3D* me, LPD3DENUMDEVICESCALLBACK a, LPVOID b);
 248  *        public: inline HRESULT EnumDevices(LPD3DENUMDEVICESCALLBACK a, LPVOID b)
 249  *            { return ((IDirect3D*)t.lpVtbl)->fnEnumDevices(this,a,b); };

 251  *        public: inline HRESULT CreateLight(LPDIRECT3DLIGHT* a, IUnknown* b)
 252  *            { return ((IDirect3D*)t.lpVtbl)->fnCreateLight(this,a,b); };
 253  *        private: HRESULT (*fnCreateMaterial)(IDirect3D* me, LPDIRECT3DMATERIAL* a, IUnknown* b);

 257  *        public: inline HRESULT CreateViewport(LPDIRECT3DVIEWPORT* a, IUnknown* b)
 258  *            { return ((IDirect3D*)t.lpVtbl)->fnCreateViewport(this,a,b); };
 259  *        private:  HRESULT (*fnFindDevice)(IDirect3D* me, LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b);
 260  *        public: inline HRESULT FindDevice(LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b)
 261  *            { return ((IDirect3D*)t.lpVtbl)->fnFindDevice(this,a,b); };
 262  *    };
 263  *
 264  * Comments:
 265  *  - In C++ IDirect3D does double duty as both the virtual/jump table and as the interface
 266  *    definition. The reason for this is to avoid having to duplicate the mehod definitions: once
 267  *    to have the function pointers in the jump table and once to have the methods in the interface
 268  *    class. Here one macro can generate both. This means though that the first pointer, t.lpVtbl
 269  *    defined in IUnknown,  must be interpreted as the jump table pointer if we interpret the
 270  *    structure as the the interface class, and as the function pointer to the QueryInterface
 271  *    method, t.fnQueryInterface, if we interpret the structure as the jump table. Fortunately this
 272  *    gymnastic is entirely taken care of in the header of IUnknown.
 273  *  - Of course in C++ we use inheritance so that we don't have to duplicate the method definitions.
 274  *  - Since IDirect3D does double duty, each ICOM_METHOD macro defines both a function pointer and
 275  *    a non-vritual inline method which dereferences it and calls it. This way this method behaves
 276  *    just like a virtual method but does not create a true C++ virtual table which would break the
 277  *    structure layout. If you look at the implementation of these methods you'll notice that they
 278  *    would not work for void functions. We have to return something and fortunately this seems to
 279  *    be what all the COM methods do (otherwise we would need another set of macros).
 280  *  - Note how the ICOM_METHOD generates both function prototypes mixing types and formal parameter
 281  *    names and the method invocation using only the formal parameter name. This is the reason why
 282  *    we need different macros to handle different numbers of parameters.
 283  *  - Finally there is no IDirect3D_Xxx macro. These are not needed in C++ unless the CINTERFACE
 284  *    macro is defined in which case we would not be here.
 285  *  - This C++ code works well for code that just uses COM interfaces. But it will not work with
 286  *    C++ code implement a COM interface. That's because such code assumes the interface methods
 287  *    are declared as virtual C++ methods which is not the case here.
 288  *
 289  *
 290  * Implementing a COM interface.
 291  *
 292  * This continues the above example. This example assumes that the implementation is in C.

 296  *        // ...
 297  *

 307  *        // ...
 308  *    }
 309  *
 310  *    // ...

 313  *        ICOM_MSVTABLE_COMPAT_DummyRTTIVALUE
 314  *        IDirect3D_fnQueryInterface,

 317  *        IDirect3D_fnInitialize,
 318  *        IDirect3D_fnSetWidth
 319  *    };
 320  *
 321  * Comments:
 322  *  - We first define what the interface really contains. This is th e_IDirect3D structure. The
 323  *    first field must of course be the virtual table pointer. Everything else is free.
 324  *  - Then we predeclare our static virtual table variable, we will need its address in some
 325  *    methods to initialize the virtual table pointer of the returned interface objects.
 326  *  - Then we implement the interface methods. To match what has been declared in the header file
 327  *    they must take a pointer to a IDirect3D structure and we must cast it to an _IDirect3D so that
 328  *    we can manipulate the fields. This is performed by the ICOM_THIS macro.
 329  *  - Finally we initialize the virtual table.
