Is there an equivalent to sched_setscheduler() that
adjusts thread priority in
stead of process priority? I want my audio thread to be higher priority than
my drawing thread. Both threads are part of the same app (process). Is this
possible in Linux v2.5?
from the source code of jack/libjack/client.c
if (pthread_attr_setschedpolicy (attributes, SCHED_FIFO)) {
jack_error ("cannot set FIFO scheduling class for RT thread");
return -1;
}
if (pthread_attr_setscope (attributes, PTHREAD_SCOPE_SYSTEM)) {
jack_error ("Cannot set scheduling scope for RT thread");
return -1;
}
memset (&rt_param, 0, sizeof (rt_param));
rt_param.sched_priority = client->engine->client_priority;
if (pthread_attr_setschedparam (attributes, &rt_param)) {
jack_error ("Cannot set scheduling priority for RT thread (%s)", strerror
(errno));
return -1;
}
