I always thought I knew the answer, but then when I searched for the
answers in the source code, it started getting really confusing! :-(
In classesh.inc we have:
TThreadPriority = (tpIdle, tpLowest, tpLower, tpNormal, tpHigher, tpHighest,
tpTimeCritical);
Then in unix/thread.inc we have:
// stupid, considering its not even implemented...
Priorities: array [TThreadPriority] of Integer =
(-20,-19,-10,0,9,18,19);
This already conflicts with the documentation which says the range is -15
to 15. Go figure!
Then we also have in linux/pthread.inc
const
THREAD_PRIORITY_IDLE = 1;
THREAD_PRIORITY_LOWEST = 15;
THREAD_PRIORITY_BELOW_NORMAL = 30;
THREAD_PRIORITY_NORMAL = 50;
THREAD_PRIORITY_ABOVE_NORMAL = 70;
THREAD_PRIORITY_HIGHEST = 80;
THREAD_PRIORITY_TIME_CRITICAL = 99;
So there you go! I'm not just as confused as you are. ;-)
