I wouldn't count on any such library existing. What you're asking for is
*strongly* platform-dependent. Some OSes don't even provide such
notifications. (The POSIX standard doesn't appear to include "file system
notifications" in its feature set.)
The cross-platform solution is to start a thread going that checks the
relevant file or directory every so often to see whether it's changed.
