Thread: inotify - IN_DELETE_SELF

Hi @ all!

First, i try du keep up of additions to my music directory; so i take the the basedir, add a watch, scan it for directories, add a watch for a hit - looping in that procedure.

Each watch its descriptor i take as a key in an array of *char to save the directories absolute path.

I asume an IN_DELETE_SELF event would me give back the watch descriptor i need to dealloc the stringspace i saved the absolut path in.

I cannot work with the IN_DELETE event, because it gives me the watch descriptor of the directory in which the deletion occurs.

But...i do not get the IN_DELETE_SELF event!? - please, what do you think...why?

Yes.

I watch the directories for actions; the happenings therein will be notified, and i get the name of the file/directory which the event produced in the member 'name' of the struct 'event' inotify posts.

If a file is created, i purpose to multicast on dbus to start the applet for completion of the mp3 tags. That is no trouble to me.

If a directory is created, i add a watch, get back the unique watchdescriptor (integer), and that indexes a *char [ 65536 ] (hey, maybe someone knows me a symbol for the max. integer value!?) where i save a pointer to the stringspace i placed the absolute path into. It seems pretty handy so far.

What i need is the <watch descriptor> the deleted directory itself watching for the index , to free the stringspace i got with malloc.

But, i do not get the IN_DELETE_SELF event, for my understanding he should work that way.

Now, that i tried it (hopefully i do not blast the thread), something faulty: size of array is too large.

Could load the possible amount of watchdescriptors from /proc/sys/fs/inotify/max_user_watches ... now, nice would it be if i could define a macro to read out that value AND is usable in a struct definition. *rofl* - possible?

...it also seems not to matter if it is a file that is deleted, or the watch is deleted by the function inotify_rm_watch inside the program - i never get IN_DELETE_SELF.
