This program may help creating ICOM_ macro.
(but this code doesn't have portability,
so some modification may be required.)
for example, if give the following codes to stdin,
we gets ICOM_ macros for IPersist.
class IUnknown
{
public:
HRESULT QueryInterface( REFIID riid, LPVOID *ppvObj) ;
ULONG AddRef() ;
ULONG Release() ;
};
export interface IPersist : public IUnknown
{
virtual HRESULT STDMETHODCALLTYPE GetClassID( CLSID *pClassID );
};
