指针问题,请高手回答

Question

IUnknown *pUnk=NULL;
       IObject *pObject=NULL;
       CoInitialize(NULL);
       CoCreateInstance(CLSID_Object, CLSCTX_INPROC_SERVER, NULL, IID_IUnknown,
(void**)&pUnk);
       pUnk->QueryInterface(IID_IOjbect, (void**)&pObject);
       pUnk->Release();
       pObject->Func();
       pObject->Release();
       CoUninitialize();
----------------------------------------------
请问
   pUnk->QueryInterface(IID_IOjbect, (void**)&pObject);
为什么不能变成
   pUnk->QueryInterface(IID_IOjbect, &pObject);------------------------------------------------------

你看人家接口的要求，人家接口要你传递void**类型的，你就传就得了
