Print a GUID variable

Question

I have a GUID variable and I want to write inside a text file its value. GUID definition is:

typedef struct _GUID {          // size is 16
    DWORD Data1;
             


        

Answer 1

I know the question is quite old, but would this work maybe?

inline std::ostream& operator <<(std::ostream& ss,GUID const& item) {
  OLECHAR* bstrGuid;
  ::StringFromCLSID(item, &bstrGuid);
  ss << bstrGuid;
  ::CoTaskMemFree(bstrGuid);
  return ss;
}
