void silc_schedule(SilcSchedule schedule);

    The SILC scheduler.  The program will run inside this function.
    When this returns the program is to be ended.  Before this function
    can be called, one must call silc_schedule_init function.

    On Windows this will block the calling thread but will continue
    to dispatch window messages, and thus can be used as the main loop
    of the program.

    On Symbian this will block the calling thread.  The Symbian Active
    Scheduler must be running before calling this function.
