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 `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.

    The `max_tasks' is the maximum number of file descriptor and socket
    tasks in the scheduler.  Set value to 0 to use default.  Operating
    system will enforce the final limit.  On some operating systems the
    limit can be significantly increased when this function is called in
    priviliged mode (as super user).
