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.
