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 "dbghelp.h".

    Please see the NT DDK documentation for specific information about
    how to write your own debugger extension DLL.

Environment:

    Win32 only.
