리눅스 errno 에러 번호 리스트

by SidePower 2020. 12. 16.

C언어로 개발된 프로그램은 기본적으로 오류가 발생되면

오류에 대한 에러번호가 부여되어 알려줍니다.

 

이 에러번호를 활용하면 쉽게 원인 파악을 할 수 있고 이에 대한 조치를 취함으로써

빠른 시간 정상화시킬 수 있을 거예요.

 

제가 사용하고 있는 CentOS 8에서 errno.h 를 찾아봤습니다.

1) /usr/include/asm-generic/errno-base.h

    errno 1 ~ 34 까지 정의.

2) /usr/include/asm-generic/errno.h

    errno 35 ~ 133 까지 정의.
