#include "unknwn.h"  
[module(name="MyLib")];  
  
[object, uuid("9E66A290-4365-11D2-A997-00C04FA37DDB")]  
__interface ICustom{  
   HRESULT Custom([in] long l, [out, retval] long *pLong);  
   [uidefault]HRESULT id0([in] long l);  
   [uidefault]HRESULT id1([in] long l);  
  
   [uidefault, propget] HRESULT get_y(int *y);
