# ReplyHostSetECID
### int ReplyHostSetECID(int lMsgId, short EAC)
호스트로부터 수신된 S2F15 (New Equipment Constant Send) 메시지에 대한 응답(`S2F16`)을 전송합니다. 사용자는 라이브러리 이벤트에서 수신된 내용을 확인하고, 설정값 변경이 성공했는지 여부를 EAC 값에 담아 이 함수를 호출하면 됩니다.

GetHostSetECID()와 사용하면 더욱 편리합니다.

if (nECCount < 0)

break;
}
AddLog(string.Format("ECID={0},VALUE={1}", nECID, strNewValue));
