I think you meant sysconf (that's what the man page points to...)?

There's no portable sysconf()'s for CPU number/activity/SMT/etc. identification. Linux has introduced a couple, but until everyone agrees on scoping rules, it's not going to be safe to implement them, since that may not end up being what The Austin Group decides will make it into the standard, so it's impossible for anyone to adopt the experimental ones Linux uses, and ensure binary backward compatibility AND standards compliance at the same time.

Thank you both for the information. As I mentioned in my first email, I'm actually doing anything with this information, I just like to see what people are running when I get crash reports.
