Routine Description:
|
|
|
|
This routine is a callback into the driver to retrieve the list of
|
|
guids or data blocks that the driver wants to register with WMI. This
|
|
routine may not pend or block. Driver should NOT call
|
|
WmiCompleteRequest.
|
|
|
|
Arguments:
|
|
|
|
DeviceObject is the device whose data block is being queried
|
|
|
|
*RegFlags returns with a set of flags that describe the guids being
|
|
registered for this device. If the device wants enable and disable
|
|
collection callbacks before receiving queries for the registered
|
|
guids then it should return the WMIREG_FLAG_EXPENSIVE flag. Also the
|
|
returned flags may specify WMIREG_FLAG_INSTANCE_PDO in which case
|
|
the instance name is determined from the PDO associated with the
|
|
device object. Note that the PDO must have an associated devnode. If
|
|
WMIREG_FLAG_INSTANCE_PDO is not set then Name must return a unique
|
|
name for the device.
|
|
|
|
InstanceName returns with the instance name for the guids if
|
|
WMIREG_FLAG_INSTANCE_PDO is not set in the returned *RegFlags. The
|
|
caller will call ExFreePool with the buffer returned.
|
|
|
|
*RegistryPath returns with the registry path of the driver
|
|
|
|
*MofResourceName returns with the name of the MOF resource attached to
|
|
the binary file. If the driver does not have a mof resource attached
|
|
then this can be returned as NULL.
|
|
|
|
*Pdo returns with the device object for the PDO associated with this
|
|
device if the WMIREG_FLAG_INSTANCE_PDO flag is retured in
|
|
*RegFlags.
