How to get PCI PDO info from FDO

NTDEV
1

Hi,
Is there a sample how to query
Bus/Dev/Fun from a PCI FDO ?
I assume its a query IRP to the PDO.

Thanks, Tom.

Create an IRP with IRP_MJ_PNP and IRP_MN_QUERY_ID and with
“Parameters.QueryId.IdType” of IRP stack set to BusQueryInstanceID /
BusQueryDeviceID / BusQueryHardwareIDs / BusQueryCompatibleIDs.

Best of Luck,
Shashi

Actually you just call IoGetDeviceProperty, specifying
DevicePropertyAddress to get back a ulong value representing the slot
(device number/function number value,) and specifying
DevicePropertyBusNumber to get back a ULONG value for the bus number.

Search the XP or later DDK for DevicePropertyAddress.
