  [in]  VARIANT            v,
  [out] IMSVidOutputDevice **pDB
);

Parameters

[in] v

VARIANT that specifies the index of the item to retrieve.

[out] pDB

Address of a variable that receives an IMSVidOutputDevice interface pointer.

Return value

S_OK	Success.
DISP_E_BADINDEX	The index is out of range.
DISP_E_TYPEMISMATCH	Wrong VARIANT type.
E_POINTER	NULL pointer argument.
