Well, I'm developing my application in Linux, but after it's done, it will be used mostly on Mac OS. So far, on regular basis, I test everything on my Mac to make sure it's working.
I guess I'll have to find another way then. One idea I have is to poll the size of the file every certain amount of time, and if it's different---there's my event. Same applies to "date/time last modified".
Is there something I can use successfully on both Linux and Mac about that?
Just to mention that the file is a text file, and it doesn't change very often. I mean, it's not constantly changing, so I'm not concerned with performance and resource issues.
Oh, here's another idea---every certain amount of time, I just compare my last saved version of the file to the current one---if different, there's my event. What do you think?

If you are on Linux/Unix, have a look at Inotify. The Ocaml bindings are
