flock ??

[Nigel Rantor <wiggly at bogo dot co dot uk>]

Hmm, ok, simple question, is there flock? I have looked around the include
files and can't find it. I know that Win32 can do it because I have seen
the stuff about locking/lock/unlock and the whole issue of DOS machines
required to load share.exe to use those features. My question is whether
or not we have the UNIX calls or whether I would have to find out what the
correct Win32 ones are.

At the moment I am trying to come up with a couple of IO manipulators for
streams so that you can just pass manipulators such as,
lock/lock(attempts,timeout) and unlock() just as you would endl
setprecision setfill and their like. So I need a reliable way to lock
files and I would rather take advantage of system calls rather that
(eeeuuughh) use temp files. Just so you know what I needed flock for.

Or indeed lockf, I have read someone looking for this (BSD??) call, I use
Linux but if they are the same, functionally, then thats what I need. You
get the idea.

Any suggestions gratefully accepted,

 Nige

p.s. Is that mail loop really gone now?
