# From: John C. Oppenheimer <jco@slinky.convex.com> # Subject: gawk-3.0.2 pid test # To: arnold@skeeve.atl.ga.us # Date: Mon, 10 Feb 1997 08:31:55 -0600 (CST) # # Thanks for the very quick reply. # # This all started when I was looking for how to do the equivalent of # "nextfile." I was after documentation and found our gawk down a few # revs. # # Looks like the nextfile functionality was added somewhere around # 2.15.5. There wasn't a way to do it, until now! Thanks for the # functionality! # # Saw the /dev/xxx capability and just tried it. # # Anyway, I wrote a pid test. I hope that it is portable. Wanted to # make a user test, but looks like id(1) is not very portable. But a # little test is better than none. # # John # # pid.ok is a zero length file # # ================== pid.awk ============ BEGIN { # getline pid <"/dev/pid" # getline ppid <"/dev/ppid" # 12/2001: switch to PROCINFO. ADR pid = PROCINFO["pid"] ppid = PROCINFO["ppid"] if (pid != ok_pid) printf "Bad pid %d, wanted %d\n", pid, ok_pid else print "PID ok" if (ppid != ok_ppid) printf "Bad ppid %d, wanted %d\n", ppid, ok_ppid else print "PPID ok" # ADR --- added # close("/dev/pid") # close("/dev/ppid") print "All Done." }
