void silc_fsm_start(void *fsm, SilcFSMStateCallback start_state);

    This function must be called after the SILC FSM context was created.
    This actually starts the state machine.  Note that, the machine is
    started later after this function returns.  The `start_state' is the
    state where the machine or thread is started.  This function is used
    with both SilcFSM and SilcFSMThread contexts.

    SilcFSM fsm;

    fsm = silc_fsm_alloc(context, destructor, context, schedule);
    silc_fsm_start(fsm, first_state);
