I've found 2 ways to shared time between threads at
the same priority that seem to work well. Here's
some psuedo-code...
For 'cooperative', just have the thread that is
yielding do...
pthread_wakeup_np(other_thread);
pthread_suspend_np(pthread_self());
If you want it preemptive, make a 3rd thread that is
at a higher priority, and from that thread do...
loop( figure out next_thread )
{
pthread_wakeup_np(next_thread);
clock_nanosleep(clock, timeslice);
pthread_suspend_np(next_thread);
}
Either of these should get what you're after.
