In "libc_r", "_r" means "reentrant".
The library is for support of the MIT pthreads, which hve been
ported and tested on FreeBSD.
This is *not* kernelk threading support, not that it's horribly
relevant at this point, since kernel threading has a lot of
drawbacks compared to user space threading for every use but
SMP scalability, and even then it is sometimes a tradeoff (even
in UnixWare 2.x or Solaris 5.x).
You should be able to use the pthreads package using the POSIX
threading document as a reference. For more information, you
should probably contact the home site for pthreads (you can find
it in the "port" package from FreeBSD, or you can find it by
looking for "pthreads" at the www.yahoo.com search site).
