Hi,
I'm reading that I can't use timer in daemon because daemon core is
based on thread.
daemonapp is using threads but nothing stops you from daemonizing your
app yourself with a simple fork.
The threads are not there for daemonizing.
They are there because a single app can host multiple services (daemons) as on Windows.
So I'm trying to create another thread which simulate
timer. My interval is quite big (~1-5 minutes), so I can't just use
sleep(60000) because daemon will hung on terminate. So I have two ideas:
1. Create loop with short sleep(1000) which on each loop check if main
interval occur and check if daemon is terminated
2. Create loop with RTL event with RtlEventWaitFor(Event, 60000) and
daemon on terminate just send event to worker so it immediately exit.
What is the best efficient solution? Maybe exists another way?
Very difficult to give an absolute answer without knowing what the
daemon is doing.
On unix, an alternate solution is to use fpSelect (Function
fpSelect(N:cint;readfds,writefds,exceptfds:pfdSet;TimeOut:PTimeVal):cint;
) and specify a time-out value.
I would go for this.
Michael.
