주어진 파일 핸들에서 파일 이름을 검색하려고합니다.C에서 Windows의 파일 핸들에서 파일 이름을 가져 오는 방법은 무엇입니까?
나는 GetFileInformationByHandle이 유용 할 수 있지만 반환하는 구조에는 파일 이름 정보 (http://msdn.microsoft.com/en-us/library/aa363788%28v=VS.85%29.aspx)가 포함되어 있지 않은 것으로 나타났습니다.
어떻게하면됩니까?
편집 : 나는 GetFileInformationByHandleEx Windows XP에서 작업을 진행하기 위해 Windows FileID에 API를 설치하려고했습니다
