Actually, now that I think about it the calls I made with ps in the program are valid for Linux but not for FreeBSD (they're for getting thread listings). Hence error code 2.
From intro(2):
2 ENOENT No such file or directory. A component of a specified pathname did not exist, or
the pathname was an empty
string.
Didn't think that a bad command would return errno=2 though..
And hopefully you've realized that your code is totally bogus
since pthread_foo() don't set errno. All the pthread_foo()
functions _return_ the error. If your code is not checking
the return values from those functions, it is wrong on every
platform, not just FreeBSD.

Well, right. I was just being lazy by checking errno, instead of checking the return value of pthread_*. It wasn't meant to be anything more than a simple set of tests. I thought that errno was set on errors though, but after reading the manpage more carefully it turns out that this is not the case.
I'll see if I can fix my checks.
Thanks for bringing this to my attention!
