WMI Library Callback Routines
This section describes required and optional routines that a kernel-mode WDM driver contains, if the driver handles WMI Minor IRPs by calling WmiSystemControl. For more information, see Calling WmiSystemControl to Handle WMI IRPs.
The DpWmiXxx names that are used in the Microsoft Windows Driver Kit (WDK) documentation are placeholders. A driver's DpWmiXxx routines can have any names that the driver writer chooses.
For information about WMI library support routines, see WMI Library Support Routines.
