[buug] checking a pid

[Ian Zimmerman]

How does one check in general if a number is a pid of a living
process, under BSD?  The old saw kill(pid, 0) only works for my own
processes - it will fail for other users' processes whether or not pid
is alive.

Under Linux, I solved this by stat'ing /proc/<pid>/ .
What is the BSD way?
