Reserved for internal use.

WdfIoTargetStarted

The I/O target is started and can process I/O requests.

WdfIoTargetStopped

The I/O target is temporarily stopped and cannot process I/O requests.

WdfIoTargetClosedForQueryRemove

The I/O target's underlying device might be removed in the near future.

WdfIoTargetClosed

The I/O target is permanently stopped and cannot process I/O requests.

WdfIoTargetDeleted

The I/O target's underlying device has been removed.

WdfIoTargetPurged

The I/O target is temporarily purged and cannot receive or process I/O requests. This constant is available starting in KMDF 1.11.
