Windows Driver Framework Extensions (Wdfkd.dll)

Extension commands that are useful for debugging drivers built with the Kernel-Mode Driver Framework (KMDF) or version 2 of the User-Mode Driver Framework (UMDF 2) are implemented in Wdfkd.dll.

These extensions can be used on Microsoft Windows XP and later operating systems. Some extensions have additional restrictions; these restrictions are noted on the individual reference pages.

Note  When you create a new KMDF or UMDF driver, you must select a driver name that has 32 characters or less. This length limit is defined in wdfglobals.h. If your driver name exceeds the maximum length, your driver will fail to load.

For more information about how to use these extensions, see Kernel-Mode Driver Framework Debugging.
