   REFIID        riid,
   IUnknown **   ppRowset);

Parameters

  • riid
    [in] The requested IID for the rowset returned in *ppRowset.

  • ppRowset
    [out] A pointer to memory in which to return the interface pointer of the underlying rowset.

Return Code

  • S_OK
    The method succeeded.

  • E_INVALIDARG
    ppRowset was a null pointer.

  • E_NOINTERFACE
    riid referenced IID_NULL.

    ppRowset did not support the interface specified in riid.

  • E_UNEXPECTED

    ITransaction::Commit or ITransaction::Abort was called, and the object is in a zombie state.

Comments

Before ppRowset is returned, the row position object calls IUnknown::AddRef on it.
