Define Documentation

#define COMCALL   STDMETHODCALLTYPE

The COM calling convention.

#define COMAPI   virtual HRESULT COMCALL

The standard COM return type and calling convention,.

#define IMPLEMENT_IUNKNOWN

(

)

Value:

virtual ULONG COMCALL AddRef()      \
                                    {   return AddRefImpl();    }       \
                                    virtual ULONG COMCALL Release()     \
                                    {   return ReleaseImpl();   }       \
                                    virtual HRESULT COMCALL QueryInterface(const IID& rIID, void** ppInterface)     \
                                    {   return QueryInterfaceImpl(rIID, ppInterface);   }                           \
                                    virtual HRESULT COMCALL InterfaceSupportsErrorInfo(const IID& rIID)             \
                                    {   return InterfaceSupportsErrorInfoImpl(rIID);    }

Implements IUnknown and ISupportErrorInfo.

#define DEFINE_INTERFACE_TABLE

(

primary_iface

)

Value:

virtual void* interface_cast(const IID& rIID)           \
                                    {                                                       \
                                        if (IsEqualIID(rIID, IID_IUnknown))                 \
                                            return static_cast<primary_iface*>(this);       \
                                        if (IsEqualIID(rIID, IID_ISupportErrorInfo))        \
                                            return static_cast<ISupportErrorInfo*>(this);

Implements interface_cast to match and downcast to the rquired interface.

#define IMPLEMENT_INTERFACE	(		iid,
			iface_name
	)

Value:

if (IsEqualIID(rIID, iid))                          \
                                            return static_cast<iface_name*>(this);

Adds a match for an interface.

#define END_INTERFACE_TABLE

(

)

Value:

return nullptr;                                     \
                                    }

End of CastInterfaceImpl implementation.
