IWiaMiniDrv::drvWriteItemProperties method (wiamindr_lh.h)
The IWiaMiniDrv::drvWriteItemProperties method writes driver item properties to a WIA hardware device.
Syntax
HRESULT drvWriteItemProperties(
BYTE *__MIDL__IWiaMiniDrv0021,
LONG __MIDL__IWiaMiniDrv0022,
PMINIDRV_TRANSFER_CONTEXT __MIDL__IWiaMiniDrv0023,
LONG *__MIDL__IWiaMiniDrv0024
);
Parameters
__MIDL__IWiaMiniDrv0021
lFlags [in]
Reserved.
__MIDL__IWiaMiniDrv0022
pWiasContext [in]
Pointer to a WIA item context.
__MIDL__IWiaMiniDrv0023
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.
__MIDL__IWiaMiniDrv0024
pmdtc [in]
Points to a MINIDRV_TRANSFER_CONTEXT structure containing the device transfer context.
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.
