What folders are monitored by FSEvents? How to get vnop_monitor_desc working?

My company develops network file system driver. I want to inform Finder about changes on server.

I need to know what folders are monitored by Finder.

There is vnop_monitor_desc to "Indicate to a filesystem that the number of watchers of a file has changed." But this vnop is KERNEL_PRIVATE.


Question: is there a way to find out what folders are monitored? Or any public alternative to vnop_monitor_desc?


Any help will be appreciated!
