The _np on the function name is to indicate its lack of portability to other OSes - it is not part of any standard. There is no posix standard way to impersonate a user/group on a per-thread basis - and, in fact, the OS X pthread_setugid_np interface is the only one I know of in common use. I'm proposing introducing the same API and semantics to FreeBSD, thereby vaguely pushing it further towards a standard. I don't really claim it's the most elegant interface, though. -- Zach Loafman | Staff Engineer | Isilon Systems
