  96  * Macros to define a COM interface
  97  */
  98 /*
  99  * The goal of the following set of definitions is to provide a way to use the same
 100  * header file definitions to provide both a C interface and a C++ object oriented
 101  * interface to COM interfaces. The type of interface is selected automatically
 102  * depending on the language but it is always possible to get the C interface in C++
 103  * by defining CINTERFACE.
 104  *
 105  * It is based on the following assumptions:
 106  *  - all COM interfaces derive from IUnknown, this should not be a problem.
 107  *  - the header file only defines the interface, the actual fields are defined
 108  *    separately in the C file implementing the interface.
 109  *
 110  * The natural approach to this problem would be to make sure we get a C++ class and
 111  * virtual methods in C++ and a structure with a table of pointer to functions in C.
 112  * Unfortunately the layout of the virtual table is compiler specific, the layout of
 113  * g++ virtual tables is not the same as that of an egcs virtual table which is not the
 114  * same as that generated by Visual C+. There are workarounds to make the virtual tables
 115  * compatible via padding but unfortunately the one which is imposed to the WINE emulator
 116  * by the Windows binaries, i.e. the Visual C++ one, is the most compact of all.
 117  *
 118  * So the solution I finally adopted does not use virtual tables. Instead I use inline
 119  * non virtual methods that dereference the method pointer themselves and perform the call.
 120  *
 121  * Let's take Direct3D as an example:
 122  *
 123  *    #define ICOM_INTERFACE IDirect3D
 124  *    #define IDirect3D_METHODS \
 125  *        ICOM_METHOD1(HRESULT,Initialize,    REFIID,) \
 126  *        ICOM_METHOD2(HRESULT,EnumDevices,   LPD3DENUMDEVICESCALLBACK,, LPVOID,) \
 127  *        ICOM_METHOD2(HRESULT,CreateLight,   LPDIRECT3DLIGHT*,, IUnknown*,) \
 128  *        ICOM_METHOD2(HRESULT,CreateMaterial,LPDIRECT3DMATERIAL*,, IUnknown*,) \
 129  *        ICOM_METHOD2(HRESULT,CreateViewport,LPDIRECT3DVIEWPORT*,, IUnknown*,) \
 130  *        ICOM_METHOD2(HRESULT,FindDevice,    LPD3DFINDDEVICESEARCH,, LPD3DFINDDEVICERESULT,)
 131  *    #define IDirect3D_IMETHODS \
 132  *        IUnknown_IMETHODS \
 133  *        IDirect3D_METHODS
 134  *    ICOM_DEFINE(IDirect3D,IUnknown)
 135  *    #undef ICOM_INTERFACE
 136  *
 137  *    #ifdef ICOM_CINTERFACE
 138  *    // *** IUnknown methods *** //

 140  *    #define IDirect3D_AddRef(p)             ICOM_CALL (AddRef,p)
 141  *    #define IDirect3D_Release(p)            ICOM_CALL (Release,p)
 142  *    // *** IDirect3D methods *** //
 143  *    #define IDirect3D_Initialize(p,a)       ICOM_CALL1(Initialize,p,a)
 144  *    #define IDirect3D_EnumDevices(p,a,b)    ICOM_CALL2(EnumDevice,p,a,b)

 149  *    #endif
 150  *
 151  * Comments:
 152  *  - The ICOM_INTERFACE macro is used in the ICOM_METHOD macros to define the type of the 'this'
 153  *    pointer. Defining this macro here saves us the trouble of having to repeat the interface
 154  *    name everywhere. Note however that because of the way macros work, a macro like ICOM_METHOD1
 155  *    cannot use 'ICOM_INTERFACE##_VTABLE' because this would give 'ICOM_INTERFACE_VTABLE' and not
 156  *    'IDirect3D_VTABLE'.
 157  *  - ICOM_METHODS defines the methods specific to this interface. It is then aggregated with the
 158  *    inherited methods to form ICOM_IMETHODS.
 159  *  - ICOM_IMETHODS defines the list of methods that are inheritable from this interface. It must
 160  *    be written manually (rather than using a macro to generate the equivalent code) to avoid
 161  *    macro recursion (which compilers don't like).
 162  *  - The ICOM_DEFINE finally declares all the structures necessary for the interface. We have to
 163  *    explicitly use the interface name for macro expansion reasons again.
 164  *    Inherited methods are inherited in C by using the IDirect3D_METHODS macro and the parent's
 165  *    Xxx_IMETHODS macro. In C++ we need only use the IDirect3D_METHODS since method inheritance
 166  *    is taken care of by the language.
 167  *  - In C++ the ICOM_METHOD macros generate a function prototype and a call to a function pointer
 168  *    method. This means using once 't1 p1, t2 p2, ...' and once 'p1, p2' without the types. The
 169  *    only way I found to handle this is to have one ICOM_METHOD macro per number of parameters and
 170  *    to have it take only the type information (with const if necessary) as parameters.
 171  *    The 'undef ICOM_INTERFACE' is here to remind you that using ICOM_INTERFACE in the following
 172  *    macros will not work. This time it's because the ICOM_CALL macro expansion is done only once
 173  *    the 'IDirect3D_Xxx' macro is expanded. And by that time ICOM_INTERFACE will be long gone
 174  *    anyway.
 175  *  - You may have noticed the double commas after each parameter type. This allows you to put the
 176  *    name of that parameter which I think is good for documentation. It is not required and since
 177  *    I did not know what to put there for this example (I could only find doc about IDirect3D2),
 178  *    I left them blank.
 179  *  - Finally the set of 'IDirect3D_Xxx' macros is a standard set of macros defined to ease access
 180  *    to the interface methods in C. Unfortunately I don't see any way to avoid having to duplicate
 181  *    the inherited method definitions there. This time I could have used a trick to use only one
 182  *    macro whatever the number of parameters but I prefered to have it work the same way as above.
 183  *  - You probably have noticed that we don't define the fields we need to actually implement this
 184  *    interface: reference count, pointer to other resources and miscellaneous fields. That's
 185  *    because these interfaces are just that: interfaces. They may be implemented more than once, in
 186  *    different contexts and sometimes not even in Wine. Thus it would not make sense to impose
 187  *    that the interface contains some specific fields.

 220  *
 221  * Comments:
 222  *  - IDirect3D only contains a pointer to the IDirect3D virtual/jump table. This is the only thing
 223  *    the user needs to know to use the interface. Of course the structure we will define to
 224  *    implement this interface will have more fields but the first one will match this pointer.
 225  *  - The code generated by ICOM_DEFINE defines both the structure representing the interface and
 226  *    the structure for the jump table. ICOM_DEFINE uses the parent's Xxx_IMETHODS macro to
 227  *    automatically repeat the prototypes of all the inherited methods and then uses IDirect3D_METHODS
 228  *    to define the IDirect3D methods.
 229  *  - Each method is declared as a pointer to function field in the jump table. The implementation
 230  *    will fill this jump table with appropriate values, probably using a static variable, and
 231  *    initialize the lpVtbl field to point to this variable.
 232  *  - The IDirect3D_Xxx macros then just derefence the lpVtbl pointer and use the function pointer
 233  *    corresponding to the macro name. This emulates the behavior of a virtual table and should be
 234  *    just as fast.
 235  *  - This C code should be quite compatible with the Windows headers both for code that uses COM
 236  *    interfaces and for code implementing a COM interface.
 237  *
 238  *
 239  * And in C++ (with gcc's g++):
 240  *
 241  *    typedef struct IDirect3D: public IUnknown {
 242  *        private: HRESULT (*fnInitialize)(IDirect3D* me, REFIID a);
 243  *        public: inline HRESULT Initialize(REFIID a) { return ((IDirect3D*)t.lpVtbl)->fnInitialize(this,a); };
 244  *        private: HRESULT (*fnEnumDevices)(IDirect3D* me, LPD3DENUMDEVICESCALLBACK a, LPVOID b);

 256  *        private:  HRESULT (*fnFindDevice)(IDirect3D* me, LPD3DFINDDEVICESEARCH a, LPD3DFINDDEVICERESULT b);

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

 316  *    };
 317  *
 318  * Comments:
 319  *  - We first define what the interface really contains. This is th e_IDirect3D structure. The
 320  *    first field must of course be the virtual table pointer. Everything else is free.
 321  *  - Then we predeclare our static virtual table variable, we will need its address in some
 322  *    methods to initialize the virtual table pointer of the returned interface objects.
 323  *  - Then we implement the interface methods. To match what has been declared in the header file
 324  *    they must take a pointer to a IDirect3D structure and we must cast it to an _IDirect3D so that
 325  *    we can manipulate the fields. This is performed by the ICOM_THIS macro.
 326  *  - Finally we initialize the virtual table.
