cciGetBrokerInfo

이 함수는 현재 브로커 환경(예: 브로커 이름, 실행 그룹 이름 및 큐 관리자 이름에 관한 정보)을 조회합니다. 정보는 CCI_BROKER_INFO_ST 유형의 구조로 리턴됩니다.
주: CciNode* 핸들을 제공하지 않아도 되고 cciGetBrokerInfo가 메시지 플로우에 대한 정보를 리턴하지 않는다는 점에서 이 함수는 cniGetBrokerInfo와 다릅니다. 따라서 cciGetBrokerInfo는 초기화 함수(예: bipInitializeUserExits, bipGetMessageParserFactorybipGetMessageFlowNodeFactory)에서 호출할 수 있습니다.

구문

void cciGetBrokerInfo(
int*                   returnCode,
CCI_BROKER_INFO_ST* broker_info_st);

매개변수

returnCode(출력)
함수의 리턴 코드를 수신합니다(출력).
가능한 리턴 코드는 다음과 같습니다.
  • CCI_SUCCESS
  • CCI_INV_BROKER_INFO_ST
  • CCI_EXCEPTION
broker_info_st(출력)
성공적으로 완료 시 관련 값으로 채워질 CCI_BROKER_INFO_ST 구조의 주소.

리턴 값

없음. 오류가 발생할 경우, returnCode 매개변수는 오류의 이유를 표시합니다.
