IWiaMiniDrv::drvAnalyzeItem method (wiamindr_lh.h)

  • Article

The IWiaMiniDrv::drvAnalyzeItem method inspects an item, and creates subitems, if necessary.

Syntax

HRESULT drvAnalyzeItem(
  BYTE *__MIDL__IWiaMiniDrv0036,
  LONG __MIDL__IWiaMiniDrv0037,
  LONG *__MIDL__IWiaMiniDrv0038
);

Parameters

__MIDL__IWiaMiniDrv0036

lFlags [in]

Reserved.

__MIDL__IWiaMiniDrv0037

pWiasContext [in]

Pointer to a WIA item context.

__MIDL__IWiaMiniDrv0038

plDevErrVal [in]

Points to a memory location that will receive a status code for this method. If this method returns S_OK, the value stored will be zero. Otherwise, a minidriver-specific error code will be stored at the location pointed to by this parameter.

Return value

On success, the method should return S_OK and clear the device error value pointed to by plDevErrVal. If the method is not fully implemented, it can return E_NOTIMPL. If the method fails, it should return a standard COM error code and place a minidriver-specific error code value in the memory pointed to by plDevErrVal.

The value pointed to by plDevErrVal can be converted to a string by calling IWiaMiniDrv::drvGetDeviceErrorStr.
