* 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 {
* HRESULT (*fnQueryInterface)(IDirect3D* me, REFIID riid, LPVOID* ppvObj);
* ULONG (*fnQueryInterface)(IDirect3D* me);
* ULONG (*fnQueryInterface)(IDirect3D* me);

* HRESULT (*fnCreateMaterial)(IDirect3D* me, LPDIRECT3DMATERIAL* a, IUnknown* b);
* HRESULT (*fnCreateViewport)(IDirect3D* me, LPDIRECT3DVIEWPORT* a, IUnknown* b);
* 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 = {
* 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.
