Hi Guys,

The Linux tthread.inc file in FPC 2.2.4 refers:

There is a constant array defined at line 55 that lists 'priority' values which I think are inverted. i.e. Currently, the listed values range from -20 to +19 and these map to tpIdle to tpRealtime. According to man nice(1), Nicenesses range from -20 (most favorable scheduling) to 19 (least favorable scheduling).

The comment on line 54 should perhaps be reworded to reflect that although it's not implemented in the current release, the user is free to use the values if he so wishes. It's not stupid, one never knows what the next guy will do with ones code.

If the above has been sorted for the next release, that's cool.

Regards,
Nino

It is mentioned in the documentation that under Linux the thread priority is a lot more fine grained than Windows and the constants defined are just suggestions for Linux developers.

I can't remember exactly we in the docs that was, but I know I read it somewhere.

My question/suggestion has little to do with the actual priority values. If you implement something, for present or future use, it must be correct or leave it out.

Please look at the code in question.
