|

*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. The caller
|
|
does NOT free this buffer.
|
|
|
|
*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. The caller does NOT free this
|
|
buffer.

Routine Description:
|
|
|
|
This routine is a callback into the driver to enabled or disable event
|
|
generation or data block collection. A device should only expect a
|
|
single enable when the first event or data consumer enables events or
|
|
data collection and a single disable when the last event or data
|
|
consumer disables events or data collection. Data blocks will only
|
|
receive collection enable/disable if they were registered as requiring
|
|
it. If the driver can complete enabling/disabling within the callback it
|
|
should call WmiCompleteRequest to complete the irp before returning to
|
|
the caller. Or the driver can return STATUS_PENDING if the irp cannot be
|
|
completed immediately and must then call WmiCompleteRequest once the
|
|
data is changed.
|
|
|
|
Arguments:
|
|
|
|
DeviceObject is the device object
|
|
|
|
GuidIndex is the index into the list of guids provided when the
|
|
device registered
|
|
|
|
Function specifies which functionality is being enabled or disabled
|
|
|
|
Enable is TRUE then the function is being enabled else disabled
