Subject: O_APPEND, file locking...
Date: Fri, 23 Jul 93 20:35:44 CES
From: Juergen Lock <nox@jelal.north.de>
Message-Id: <9307231835.AA00268@jelal.north.de>
quick question: on what filesystems does O_APPEND (or fopen (.. "a"))
work with > 1 processes writing to the same file? i doubt it does on
GEMDOSfs, but on others? reason i ask is should i put locking code
around simple one-line fprintfs to logfiles.. i would rather not :-)
i also noticed that flock etc don't use F_SETLKW, is there a deeper
reason?
(i'm just preparing an `update' for the old hacked-up smail 2.5 that
some of use are still using here... works quite well with elm and
taylor uucp on MiNT now btw.)
