Re: Thread behaviour using pthread

Hello Igor,

I have tried using pthread library on Linux (2.6 kernel) and found that
setting parameters in the attr structure
do not seem to change anything in the thread behaviour - changing sched
policy (RR, FIFO) or RT priority. So, it seems that any changes to attr
structure for a thread are transparent. The only way I could change the
behaviour is by using process level calls like sched_setscheduler etc.on a
thread.

Is there anything I am missing?

Yes. You must set the inheritsched attribute to PTHREAD_EXPLICIT_SCHED;
otherwise the thread created inherits the schedpolicy and schedparam
attributes from the creating thread.

HTH,
Loic.
