Could you please elaborate, what are you trying to say ? 1) The only variable exported to a process from libc is "environ", not __environ or _environ. Look at src/lib/libc/stdlib/getenv.c for an example, and confirmation. 2) Your code assigns environ = NULL, which is why I felt the above commit has relevancy to you. You should be aware that there are many different conditions where clearing environ on FreeBSD behaves differently compared to other OSes; the commit makes it compatible with pretty much everything. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
