Basic WinDbg question

[karthik.moc]

Hi,

I am a novice windbg user. When I try to list the processes via the
extension command,

!process 0 0, I am getting a display of "No Export process" found.
Could you please explain me what is "Export Process" and why am I
getting this error on my system?

Thanks & Regards,
Karthikeyan S.

Are you using it in a kernel-debugger session ?

If NOT, then, `.tlist` is your friend.

The debugger complains `no export` named `process` found,
because most of the debugger extension commands are implemented
as exported functions from the related dll.

For example:
C:\debuggers\winxp>link -dump -exports kdexts.dll | findstr /i process
191 BE 001476F0 process

Hi Ivan,

Thanks a lot for your immediate response. This really encourages me to
learn things further.

As per my current understanding I can't use extension commands
exported by kdexts.dll as it is solely for "kd". So, It means I could
use only functions exported by "exts.dll" in windbg.

Thanks & Regards,
Karthik.

Technically not true for all the commands and for all the debugger-extension
DLLs
Each command has an applicable environment (user-mode, kernel-mode,
user-mode-dump, kernel-mode-dump, etc, etc) that is listed
in the documentation of the command.
There are kernel-mode only commands that implemented in other DLLs,
and the other way around.
