The documentation for GLib.Unix.SignalSource states "In GLib versions before 2.36, only `SIGHUP`, `SIGINT`, `SIGTERM` can be monitored. In GLib 2.36, `SIGUSR1` and `SIGUSR2` were added. In GLib 2.54, `SIGWINCH` was added." The example is in Genie, so significant leading whitespace and types are declared after the identifier with a colon. Save as unix_signal_example.gs and compile like any other Vala program: [indent = 4] init var main = new MainLoop() var handler = new SignalHandler( main ) Unix.signal_add( Posix.SIGINT, handler.quit ) print (@"To end the process use: kill -2 $((int)Posix.getpid()) or CTRL+C") main.run() class SignalHandler _mainloop:MainLoop construct( mainloop:MainLoop ) _mainloop = mainloop def quit():bool print( @" Process $((int)Posix.getpid()) has received SIGINT, ending..." ) _mainloop.quit() return Source.REMOVE For segmentation faults you may find inspiration from vala-stacktrace: https://github.com/PerfectCarl/vala-stacktrace Thanks for keeping us updated, Al _______________________________________________ vala-list mailing list vala-list@gnome.org https://mail.gnome.org/mailman/listinfo/vala-list
