Re: GetLastError / SetLastError functionality from inside a driver

Let's get to the substance of Don's reply. You have attempted to force the
world of drivers into a user mode mindset. I won't work. Read, study, and
quit bottom posting. I usually don't scroll down since bottom posters
mostly don't have anything useful.

If you HAVE to leap into this for whatever reason, that doesn't mean you
will receive a drivers 101 tutorial via this newsgroup.

read the "Windows Internals" book by Russinovich and Solomon. Note: you
mention file system filters, these are some of the toughest kernel drivers
to get right, don't even go near them with the questions you are asking.

Hi,

Please cooperate if this appears to be a trivial question.

I am newbie to this.

I just wanted to know how is it possible to get functionality similar
to GetLastError() and SetLastError() inside a driver?

If there is something more particular about a file system filter
driver, please advise me about that too because i am working on a file
system filter.

Thanks for any help.

Regards,
Aman.

Is there a way to set last error (SetLastError() ) from the kernel
mode , so that when GetLastError() is called in the user mode, the
error that was set in the kernel mode is returned?

Your reply is appreciated Don.
Somehow i have no other choice but to dive into these drivers. It is
tough going i know but i guess i'll eventually find a way. It'll take
time i do understand.

For now if you can guide me on how do i send the error code back. Is
it to be passed back as the part of the IRP or some other way?

It is a legacy filter and not a minifilter.

Thanks again.

Regards,
Aman.
