Module Name:
wdbgexts.h
Abstract:
This file contains the necessary prototypes and data types for a user
to write a debugger extension DLL. This header file is also included
by the NT debuggers (WINDBG & KD).
This header file must be included after "windows.h" and "imagehlp.h".
Please see the NT DDK documentation for specific information about
how to write your own debugger extension DLL.
Environment:
Win32 only.
