samba - Mar 2005 - file locking

Is file locking dependent on the editor or we can control it via the
oplocks option? here's the scenario: I usually use vi from the
console. However, some of my colleagues might work on the same file
from the windows machine using notepad, Jedit, dreamweaver etc. What
is the best way to lock files?

You need an oplock-aware kernel and applications that are locking-aware
of each other (ie. POSIX apps that attempt to get an advisory fcntl lock
over any region the read/write). I don't know of any posix apps that do
this (certainly not vi).
