Timer signal results in "Alarm clock"

["Andre' Karwath" <Andre Karwath informatik tu-chemnitz de>]

Hello,

I'd like to connect the timer signal SIGALRM to a signal handler

  signal (SIGALRM, timer_signal_handler);

and start the timer

  itimerval t;
  t.it_value.tv_sec=1;
  t.it_value.tv_usec=0;
  setitimer (ITIMER_REAL, &t, NULL);

All this works fine if I start the timer before I call gtk_main () and
the timer_signal_handler function gets called as usual. But if I setup
the timer after gtk_main (), the program stops after the adjusted time
with the message "Alarm clock".

Now, I really would like to avoid this message and the stopping of my
program, as well. I need to react myself within timer_signal_handler.

I'm sure, there exists a solution ;) Have anyone a good idea?

Thanks a lot.
