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 "dbghelp.h".
Please see the NT DDK documentation for specific information about
how to write your own debugger extension DLL.
Environment:
Win32 only.

Copies the value of the specified field into pOutValue assuming TypeAddress
points to start of the type in debugee.
If the Field is NULL and the size of Type is <= 8 Whole type value is read into
pOutValue. This is to allow to read in primitive types suchas ULONG, PVOID etc.
If address is zero this considers Type a global variable.
It raises an exception if OutSize is less than size to be copied.
Returns 0 on success, errorvalue (defined with SYM_DUMP_PARAM) otherwise.
