Re^2: Best practices for modifying a file in place: q's about opening files, file locking, and using the rename function

If you write all the programs that write to the files, you can use locks, but take care, file locks is not a real restriction, you can ignore it if you want

Not necessarily. Some OSes (Windows, for example) have mandatory locks (as opposed to advisory locks).

Even the "mandatory" locks on Windows' aren't infallible when you get into network shared filesystems, especially SMB/Samba connections, because the whole modification stack isn't under one machine's control. You are right: they profess to be mandatory and cause you grief if you ignore them, but they cause you grief anyway when the remote system does unexpected things. -- `[ e d @ h a l l e y . c c ]`	[reply]
