How to query 802.11 OIDs from NDIS

Archived from groups: microsoft.public.development.device.drivers,microsoft.public.pocketpc.developer.networking,microsoft.public.windowsxp.device_driver.dev (More info?)

Hi all,

I have written a simple application in which I open the handle to file
NDISUIO_DEVICE_NAME and then use IOCTL_NDISUIO_QUERY_OID_VALUE in the call
to DeviceIOControl() to query different 802.11 OIDs like OID_802_11_SSID,
OID_802_11_RSSI etc etc and some other OIDs like OID_GEN_RCV_OK,
OID_GEN_XMIT_OK. The sample code is shown below:

BOOL MyClass::IOQueryOID(HANDLE hNdisUio, PTCHAR adapter_name, NDIS_OID oid,
LPVOID pData, int length)
{
DWORD dwBytesReturned = 0;
PNDISUIO_QUERY_OID pQOid=NULL;
DWORD dwQueryOidBufferSize = sizeof(NDISUIO_QUERY_OID) + length;

pQOid = (PNDISUIO_QUERY_OID) new BYTE[dwQueryOidBufferSize];
if (!pQueryOid)
{
return false;
}

pQueryOid->Oid = oid;
pQueryOid->ptcDeviceName = adapter_name;

if(!DeviceIoControl(hNdisUio,
IOCTL_NDISUIO_QUERY_OID_VALUE,
pQueryOid,
dwQueryOidBufferSize,
pQueryOid,
dwQueryOidBufferSize,
&dwBytesReturned,
0))
{
delete [] pQueryOid;
return false;
}

if(pData != NULL && length > 0)
memcpy(pData, &pQueryOid->Data[0], (dwBytesReturned < length) ?
dwBytesReturned : length);

delete [] pQueryOid;
return true;
}

But now i want to open file DD_NDIS_DEVICE_NAME and want to query same
OIDs..how should i do this?

Thanks,

Arsalan

Hi,

I am developing an application on Pocket PC 2003 which uses NDISUIO to query
different oids like OID_802_11_FRAGMENTATION_THRESHOLD, OID_11_RTS_THRESHOLD
etc. However I am getting Not Supported for these OIDs when I query for the
supported OIDs from NDISUIO driver. But even then if I need to query these
OIDs, then please tell me what should i do? Is there any other interface
available for this? Or can I query the NIC driver directly rather than using
the NDISUIO driver? My application runs on Pocket PC 2003.

Thanks,

Arsalan
