### 콜백 라우터 추가하기 { #add-the-callback-router }

이 시점에서, 위에서 만든 콜백 라우터 안에 *콜백 경로 처리(들)*(즉 *external developer*가 *external API*에 구현해야 하는 것들)을 준비했습니다.

이제 *여러분의 API 경로 처리 데코레이터*에서 `callbacks` 파라미터를 사용해, 그 콜백 라우터의 `.routes` 속성(실제로는 routes/*경로 처리*의 `list`)을 전달합니다:

  // scheduled on that same threadpool, causing a deadlock in cases where the
  // caller of event_mgr->ThenExecute() blocks on the completion of the callback
  // (as in the case of ConstOp kernel creation on GPU, which involves copying a
