Is there in a resource manager, a mechanism to be advised that a client,
which did an open, is died before doing a close?

Thanks,
Alain.

The kernel synthesizes an _IO_CLOSE when the client dies. So, the answer
is “technically” no – you will get the close() when the client dies.

Ok, I actually use procmgr_daemon() for my VIC (Very Important Client) and
procmgr_event_notify(PROCMGR_EVENT_DAEMON_DEATH, &event) in my server.

I’ll continue with this method.
Thanks,
Alain.
