SilcSchedule silc_schedule_init(int max_tasks, void *app_context);

    Initializes the scheduler. This returns the scheduler context that
    is given as argument usually to all silc_schedule_* functions.
    The `max_tasks' indicates the number of maximum tasks that the
    scheduler can handle. The `app_context' is application specific
    context that is delivered to all task callbacks. The caller must
    free that context.  The 'app_context' can be for example the
    application itself.
