Re: Whats the best way to sleep a thread?

Hello Matt,
You may want to look at the thread's TCB structure because the delay
of the thread is just about the setting or unsetting a certain member
of this structure. I am now out of my office, and I don't have the
proper documentation, but I willprovide you with the algorithm for you
to see what is going on actually when the system delay's a thread and
wakes it up.
You may also want to see if you are compiling Checked Build or Free
Build.

Hi all

I have an interesting situation: An Ndis driver creates a thread in
MiniportInitialise. For now thwe thread does nothing else.

When the system goes to standby the thread does a
KeWaitForSibngleObject on an event (which is never set) with a timeout
of 10 seconds.

However, I have noticed different behaviour coming out of Hibernate
while attatched to WinDbg.

Without the thread, the PC comes out of Hibernate attatched to the
debugger.

With the thread, the PC comes out of Hibernate not attatched to the
debugger.

I have also tried KeDelayExecutionThread() which gives exactly the
same results.

So the question is, is there a way to halt a thread without affecting
system functionality in this respect?

Thanks in advance.
