如何用C语言实现实现webbrowers 的IDocHostUIHandler接口？

下面给出了用Ｃ语言实现webbrowers 的IOleClientSite方法
// IOleClientSite接口 函数
HRESULT STDMETHODCALLTYPE Site_QueryInterface(IOleClientSite FAR* This, REFIID riid, void ** ppvObject);
HRESULT STDMETHODCALLTYPE Site_AddRef(IOleClientSite FAR* This);
HRESULT STDMETHODCALLTYPE Site_Release(IOleClientSite FAR* This);
HRESULT STDMETHODCALLTYPE Site_SaveObject(IOleClientSite FAR* This);
HRESULT STDMETHODCALLTYPE Site_GetMoniker(IOleClientSite FAR* This, DWORD dwAssign, DWORD dwWhichMoniker, IMoniker ** ppmk);
HRESULT STDMETHODCALLTYPE Site_GetContainer(IOleClientSite FAR* This, LPOLECONTAINER FAR* ppContainer);
HRESULT STDMETHODCALLTYPE Site_ShowObject(IOleClientSite FAR* This);
HRESULT STDMETHODCALLTYPE Site_OnShowWindow(IOleClientSite FAR* This, BOOL fShow);
HRESULT STDMETHODCALLTYPE Site_RequestNewObjectLayout(IOleClientSite FAR* This);

//用C语言实现虚表
IOleClientSiteVtbl MyIOleClientSiteTable = {Site_QueryInterface,
Site_AddRef,
Site_Release,
Site_SaveObject,
Site_GetMoniker,
Site_GetContainer,
Site_ShowObject,
Site_OnShowWindow,
Site_RequestNewObjectLayout};


_IOleClientSiteEx *_iOleClientSiteEx;

// 用 IOleClientSite 虚表指针初始化IOleClientSite 对象
_iOleClientSiteEx = (_IOleClientSiteEx *)(ptr + sizeof(IOleInPlaceFrameEx) + sizeof(IOleObject *));
_iOleClientSiteEx->client.lpVtbl = &MyIOleClientSiteTable;

我的问题是　如何用C语言实现实现webbrowers 的IDocHostUIHandler接口，IDocHostUIHandler这个接口都有那些函数？

上面的代码编译连接通过
现在的问题是: 1.每个接口函数的返回值.该如何确定.看例子有的返回S_OK,有的返回1,有的返回NOTIMPLEMENTED
              依据是什么,或者说需要看什么文挡
               2.QueryInterface和GetHostInfo的代码如何写.
             3.这个接口的函数GetHostInfo是自己写的程序调用,还是IE调用.如何是自己写的程序调用,在什么情 
                 况下调用.

目前的问题是 QueryInterface如何写. 
这个接口的函数GetHostInfo是自己写的程序调用,还是IE调用.如何是自己写的程序调用,在什么情 况下调用.
