  • Artículo

[Advertencia: UMDF 2 es la versión más reciente de UMDF y sustituye a UMDF 1. Todos los controladores UMDF nuevos deben escribirse con UMDF 2. No se agregan nuevas características a UMDF 1 y hay compatibilidad limitada con UMDF 1 en versiones más recientes de Windows 10. Los controladores universales de Windows deben usar UMDF 2. Para obtener más información, consulta Introducción con UMDF.

La enumeración WDF_FILE_INFORMATION_CLASS identifica los tipos de información de archivo que un controlador puede obtener o establecer.

Comentarios

La enumeración WDF_FILE_INFORMATION_CLASS se usa como valor de entrada para IWDFIoRequest2::GetQueryInformationParameters y como valor de salida de IWDFIoRequest2::GetSetInformationParameters.

Para la mayoría de los valores que define la enumeración WDF_FILE_INFORMATION_CLASS , el archivo de encabezado wdm.h o ntifs.h define una estructura con nombre FILE_XXXX_INFORMATION que el controlador puede usar al obtener o establecer la información del archivo.

Para obtener más información sobre el valor de enumeración y las estructuras asociadas, vea la descripción del parámetro FileInformationClass de ZwQueryInformationFile y ZwSetInformationFile.
