File monitoring using Grand Central Dispatch

Question

I\'m using the code example by David Hamrick to monitor a file using GCD.

int fildes = open(\"/path/to/config.plist\", O_RDONLY);

dispatch_queue_t queue = d         


        

Answer 1

After a little bit a research I found out :

=> I was getting the flag DISPATCH_VNODE_DELETE

I was monitoring ~/Library/Preferences/com.apple.dock.plist As I found out, changing the dock orientation, deletes the original file and replaces it with a new one.

Therefore, the monitoring stopped.

The same author proposes a solution where in case of deletion, the GCD block call itself to continue the monitoring.
