[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]

  [out] BSTR *Clsid
);

Parameters

[out] Clsid

Pointer to a variable that receives a string representation of the CLSID.

Return value

The caller must free the returned string, using the SysFreeString function.
