Module Name:
|
|
|
|
gdisup.h
|
|
|
|
Abstract:
|
|
|
|
This is the NT Watchdog driver implementation.
|
|
This module implements support routines for
|
|
watchdog in win32k.

|
|
|
Environment:
|
|
|
|
Kernel mode only.
|
|
|
|
Notes:
|
|
|
|
This module cannot be moved to win32k since routines defined here can
|
|
be called at any time and it is possible that win32k may not be mapped
|
|
into running process space at this time (e.g. TS session).
