threads implementation

[highland]

Hello
I wanted to write simple program swithing between threads.
My threads are simple functions.
I created itimerval timer, which sends SIGVTALRM every 100ms.
In my timer_handler() procedure i would like to choose
aprioprate thread to continue. My problem is:
How does stack looks like when thread (my function) is interrupted by
SIGVTALRM ? What information should i save, and how can i back to
selected thread in timer_handler() ?
Do you know some good web pages/HOWTO about it ?

Thanx for any help
Michal

Maybe you can find some inspiration in this code:
