can pthread be preemptive ?
 

Hi all,

I have read about that pthread (or in general, userland threads) are cooperative. Is it true? Is there a "preemptive mode" for pthread?

Thanks,
Wei Xu

On linux (using pthreads) they are treated as separate processes.

You can see that using "ps -eLf", "ps axms" or "top -H". Each thread is scheduled independently by the kernel.
