I'm using kqueue for detecting file-events; for additional information
I add a struct to udata, when registering an event with kevent.
When I delete an event, will be udata deleted too, or do I have to
manage the memory for the structs with an own implementation?
It is up to you to free udata.
kevent is triggered when a file is renamed. How do I get the new name?
Is there an extra function? In the moment, I see only the possibility
by searching the filesystem(folder) for a new name.
A good question to which I unfortunately do not have the answer to. I
think in principle it is impossible to get the file name by file
descriptor alone (it could have multiple names). In practice I would
just treat NOTE_RENAME as a sequence of unlink/link. I believe tools
like lsof use the system name cache to map fds to names, but that is not
very reliable.
If you need more help with kqueue you might try the hackers@ mailing
list, more technical people read that list.
