[fpc-pascal] values for ThreadSetPriority

[Seth Grover]

After reading the online docs, and searching this list, I'm still
confused. Hopefully someone can straighten me out.

http://www.hu.freepascal.org/docs-html/rtl/system/threadsetpriority.html
says that it takes for a priority values from -15 to 15. The comment
to the right of the declaration says that "0" is normal. Are these
numbers like nice's, where negative numbers are more favorable (higher
priority) and positive numbers are less favorable (lower priority)?

Also, to further confuse my mind, I found this:
http://community.freepascal.org:10000/docs-html/rtl/classes/tthreadpriority.html
which has some enumerations. How do those come into play? Are those
just for TThread descendents?

I'm just trying to find the correct cross-platform approach for
changing thread priority of threads started with BeginThread.

Thanks,

-SG
