-Routine Description:
-
- The PnP Manager sends this IRP to gather information about
- devices with a relationship to the specified device.
- Bus drivers must handle this request for TargetDeviceRelation
- for their child devices (child PDOs).
-
- If a driver returns relations in response to this IRP,
- it allocates a DEVICE_RELATIONS structure from paged
- memory containing a count and the appropriate number of
- device object pointers. The PnP Manager frees the structure
- when it is no longer needed. If a driver replaces a
- DEVICE_RELATIONS structure allocated by another driver,
- it must free the previous structure.
-
- A driver must reference the PDO of any device that it
- reports in this IRP (ObReferenceObject). The PnP Manager
- removes the reference when appropriate.
