Hello!
I just want to understand DDK unidrv example. As far as I've read unidrv can
include two plug-ins. So,I try OEMDEV structure to send some data from one to
another. But when I add some more fields in OEMDEV stucture (I mean besides
OEM_DMEXTRAHEADER and dwDriverData, which are happened in DDK example), the
data stopped translated between the plug-ins. Is OEMDEV structure of a fix
size, or my private data should be described anywhere more?
To fill private members I use the following:
LONG APIENTRY OEMDocUICallBack(PCPSUICBPARAM pCallbackParam)
{
......
PCBUSERDATA pUserData = (PCBUSERDATA) pCallbackParam->UserData;
POEMDEV pOEMDev = (POEMDEV)pUserData->pOEMUIParam->pOEMDM;
........
pOEMDev->dwDriverData1 = 1;
pOEMDev->dwDriverData2 = 2;
pOEMDev->dwDriverData3 = 3;
.......
}
