-       * 만약 main-thread, tdm-thread에서 동시에 synchronous event가 발생되게 되면 deadlock발생됨\r
-               - 양쪽에서 모두 pthread_cond_wait에서 대기\r
-       * sync event는 한쪽 thread에서만 발생되도록 보장되어야 함.\r
-               - tdm-thread -> main-thread방향으로만 sync event전달만 허용\r
-       * sync event의 종류\r
-               - backend에서 스스로 발생되는 event들만 가능\r
-               - output status변경중에 connection/disconnection, virtual output creation/destruction\r
