Function silc_schedule_signal_register
SYNOPSIS

        void silc_schedule_signal_register(SilcSchedule schedule,
                                           SilcUInt32 signal,
                                             SilcTaskCallback callback,
                                             void *context);

DESCRIPTION

        Register signal indicated by `signal' to the scheduler.  Application
        should register all signals it is going to use to the scheduler.
        The `callback' with `context' will be called after the application
        has called silc_schedule_signal_call function in the real signal
        callback.  Application is responsible of calling that, and the
        signal system will not work without calling silc_schedule_signal_call
        function.  The specified `signal' value will be also delivered to
        the `callback' as the fd-argument.  The event type in the callback
        will be SILC_TASK_INTERRUPT.  It is safe to use any SILC routines
        in the `callback' since it is actually called after the signal really
        happened.

        On platform that does not support signals calling this function has
        no effect.

EXAMPLE

        Typical signal usage case on Unix systems:

        struct sigaction sa;
        sa.sa_handler = signal_handler;
        sigaction(SIGHUP, &sa, NULL);
        sigaction(SIGINT, &sa, NULL);
        silc_schedule_signal_register(schedule, SIGHUP, hup_signal, context);
        silc_schedule_signal_register(schedule, SIGINT, int_signal, context);

        static void signal_handler(int sig)
        {
          silc_schedule_signal_call(schedule, sig);
        }

        The `signal_handler' can be used as generic signal callback in the
        application that merely calls silc_schedule_signal_call, which then
        eventually will deliver for example the `hup_signal' callback.  The
        same `signal_handler' can be used with all signals.
