Using GUIDs in Drivers

Drivers and other system components use globally unique identifiers (GUIDs) to identify a variety of items. System components define GUIDs for items such as device setup classes, PnP events, WMI events, and still image events. Driver writers can create GUIDs for items such as device interface classes, custom PnP events, and custom WMI events. Drivers and applications include header files that define the GUIDs that they use.

This section includes the following topics:

Defining and Exporting New GUIDs

Including GUIDs in Driver Code

For information about using GUIDs in user-mode applications, see Microsoft Windows SDK documentation.
