safe function... and I have found good implementations of getpwnam_r in other OSes
and some not so good looking ones as well but I haven't really been able to integrate
one into our current system which appears to be centralized in lib/libc/net/nsdispatch.c.
There is a lot of global state in there that would hinder the ability to make a fully reentrant
function.
It may be that the whole subsystem must be replaced before this is really possible in a clean
way.
Take that above statement however you wish... I am pretty new to this whole kernel/OS thing :).

Hmmm for some reason I thought that would be the simple answer... also at one point in time unistd.h gave me trouble when I didn't build libc under world.
Is libc_r the correct place to put getpwnam_r anyway? My understanding
is that just
where the userland thread implementation goes.
I never got a clear answer to that question either... basically I haven't made much progress due to being unclear on several of these little issues.

Or even better would be just building libc. I have been working on my
getpwnam_r assignment...
examining implementations in both Darwin and NetBSD and started trying
to implement some of
this code for FreeBSD... Its not anywhere even near the goal in sight
as I am still learning the
build system.
Do I always have to build world or can I get away with just making some subdirectories? If so what is the best way to do this?
If you're just experimenting wiht getpwnam_r, you can just rebuild libc_r:
cd /usr/src/lib/libc_r make make install
