IWiaMiniDrv::drvInitItemProperties method (wiamindr_lh.h)
The IWiaMiniDrv::drvInitItemProperties method initializes WIA driver item properties for each item in an application item tree.
Syntax
HRESULT drvInitItemProperties(
BYTE *__MIDL__IWiaMiniDrv0013,
LONG __MIDL__IWiaMiniDrv0014,
LONG *__MIDL__IWiaMiniDrv0015
);
Parameters
__MIDL__IWiaMiniDrv0013
lFlags [in]
Reserved. Set to zero.
__MIDL__IWiaMiniDrv0014
pWiasContext [in]
Pointer to a WIA item context.
__MIDL__IWiaMiniDrv0015
plDevErrVal [out]
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 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.
Remarks
The IWiaMiniDrv::drvInitItemProperties method is called once per application for each item in the item tree.
