You might get some better quality answers if you provide some more information about the specific context you are working in. – Colin D Apr 20 '12 at 12:56

Directly from the man page:
NOTES
flock() does not lock files over NFS. Use fcntl(2) instead: that does work over NFS, given
a sufficiently recent version of Linux and a server which supports locking.
I'm not saying using lock files is the better option over NFS, though.

`fcntl` locks or `lockf` should be used instead. `flock` is deprecated but plenty of broken software insists on still trying to use it... – R.. GitHub STOP HELPING ICE Apr 20 '12 at 13:10

some reasons not to use flock():
It does not work over NFS.
It is just an advisory lock, even if you use a lock there is no guarantee other processes will respect it.
