Here is some sample code demonstrating how the new FSEvents API works in Leopard

On the plus side:

• Each event has a unique ID
• The events are stored on the disk in a log, i.e. in theory you can search and replay the events!

On the minus side:

• It only really provides directory changed, and volume mount/unmount messages
• It doesn't say when the event occurred, the ID simply implies an order
• It will only provides events about directories the user has access to (security)

Meanwhile, the low-level fsevent support still does work in Leopard - and so fseventer will be updated soon has been updated (v2.1 14Jan08) to support this.
