Mac File Change Event

Does OS X have an easy OS hook to detect file changes in the filesystem?

What I need is a way to detect when a user writes to a filesystem in real time - as you might have in a virus scanner that needs to scan any changes that get written to the filesystem.

The File Notification APIs deal with this, specifically FNSubscribe() and FNSubscribeByPath() in File.h:

Thanks!  That gave me a starting point to solve my issue. For anyone else going down this road, in addition to FNSubscribe, OS X has the kqueue interface which also provides some of this information.

Thanks for the quick response.
