Track a file [C++ or Python]

How can I "track" a file using C++, or Python (I'm guessing C++ will be way more powerfull. Just putting Python in there in case there is a way with it, which wou开发者_运维问答ld be simpler than C++).

When I mean track, I mean registering any moving of the file to a different path, changes in name, etc. Changes in the actual content of the file isn't an issue.

You can do that using launchd on OS X. Check out: Is there a command like "watch" or "inotifywait" on the Mac?
