Thanks, Russell! I didn't know that -- it may come in handy.
Unfortunately, I oversimplified my example. What I've actually working on
is a tcpdump-like process listening on a live interface that dynamically
adjusts its pcap filter based on certain events. What I really want to
do is to be able to pipe directly into argus if at all possible and avoid
writing to disk.
Would getting rid of the fclose(stdin) break anything, as far as anyone
