posix_pathconf 함수에 대한 질문

나는 파이썬에서 posix_pathconf 함수를 사용 중인데, 이 함수의 사용법과 결과값에 대한 설명을 듣고 싶습니다.

나는 posix_pathconf 함수를 사용하여 파일의 경로를 확인하는 데 문제가 있습니다. 파일의 경로가 존재하는지 여부를 확인하는 코드를 작성했는데, 파일이 존재하지 않아도 True를 반환하는 현상이 발생합니다. 이 현상은 왜 발생하고 어떻게 해결할 수 있는지 알려주세요.

파일 경로 확인 코드는 다음과 같습니다.

python

import os

import posix_pathconf



path = '/path/to/file'



if posix_pathconf.PATHCONF(path).PC_NAME == 0:

    print('파일이 존재하지 않습니다.')

else:

    print('파일이 존재합니다.')


위 코드는 파일이 존재하지 않아도 True를 반환하는 현상이 발생합니다. 이 현상은 왜 발생하고 어떻게 해결할 수 있는지 알려주세요.
