[경고: UMDF 2는 UMDF의 최신 버전이며 UMDF 1을 대체합니다. 모든 새 UMDF 드라이버는 UMDF 2를 사용하여 작성해야 합니다. UMDF 1에 새 기능이 추가되지 않으며 최신 버전의 Windows 10 UMDF 1에 대한 지원이 제한되어 있습니다. 유니버설 Windows 드라이버는 UMDF 2를 사용해야 합니다. 자세한 내용은 UMDF를 사용하여 시작 참조하세요.]

WDF_FILE_INFORMATION_CLASS 열거형은 드라이버가 가져오거나 설정할 수 있는 파일 정보의 형식을 식별합니다.

설명

WDF_FILE_INFORMATION_CLASS 열거형은 IWDFIoRequest2::GetQueryInformationParameters에 대한 입력 값으로 사용되며 IWDFIoRequest2::GetSetInformationParameters의 출력 값으로 사용됩니다.

WDF_FILE_INFORMATION_CLASS 열거형이 정의하는 대부분의 값에 대해 wdm.h 또는 ntifs.h 헤더 파일은 드라이버가 파일 정보를 가져오거나 설정할 때 사용할 수 있는 FILE_XXXX_INFORMATION 명명된 구조를 정의합니다.

열거형 값 및 관련 구조체에 대한 자세한 내용은 ZwQueryInformationFile 및 ZwSetInformationFile의 FileInformationClass 매개 변수에 대한 설명을 참조하세요.
