How to set up a thread callback?

NTDEV
1

Hi all!
How can I set up a routine that will be called when a thread gets activated
by the scheduler?
Basically, what I want is to detect a thread switch before newly activated
thread continues its execution.

TIA,

Vladimir

It’s been awhile since I’ve looked at this, but my recollection is that the
KiSwapContextNotifyRoutine (set by KeSetSwapContextNotifyRoutine) is only
called by the SMP kernel on a thread switch. It does not work on the single
processor kernel.

Vladimir:

Where they are documented? I seached my XP IFS and did see them. Are they
documented in .NET IFS?

Thanks.

Found them. However it is not in XP IFS. Does anyone know if the return
value of PTHREAD_SELECT_NOTIFY_ROUTINE would influence the selected thread
to be scheduled or not?

How to set up a thread callback? IIRC they were described in one of the “undocumented NT” websites or books.

My recollection is that if your THREAD_SELECT_NOTIFY_ROUTINE returns FALSE, then the thread won’t be scheduled.
