);

Parameters

• itinfo
  Type information to return. Pass zero to retrieve type information for the IDispatch implementation.

Returns an E_POINTER if pptinfo is invalid.

Returns TYPE_E_ELEMENTNOTFOUND if itinfo is not zero.

Returns S_OK if is successful.

Otherwise, returns an HRESULT from one of the calls to retrieve the type.

The HRESULT indicates the error and can be one of the following standard constants, or other values not listed.
