As the documentation says, flocks are merely advisory, meaning they only work when all programs that access the file cooperate and use the same locking mechanism. Also, as Corion already noted, a lot of file locking mechanisms don't work properly over a lot of different network file systems.

Why do you want to lock the files - are you trying to coordinate different processes of yours, or are you actually trying to prevent others from accessing the files?
