[Peringatan: UMDF 2 adalah versi terbaru UMDF dan pengganti UMDF 1. Semua driver UMDF baru harus ditulis menggunakan UMDF 2. Tidak ada fitur baru yang ditambahkan ke UMDF 1 dan ada dukungan terbatas untuk UMDF 1 pada versi Windows 10 yang lebih baru. Driver Universal Windows harus menggunakan UMDF 2. Untuk informasi selengkapnya, lihat Mulai menggunakan UMDF.]

Enumerasi WDF_FILE_INFORMATION_CLASS mengidentifikasi jenis informasi file yang dapat diperoleh atau diatur oleh driver.

Keterangan

Enumerasi WDF_FILE_INFORMATION_CLASS digunakan sebagai nilai input untuk IWDFIoRequest2::GetQueryInformationParameters dan sebagai nilai output dari IWDFIoRequest2::GetSetInformationParameters.

Untuk sebagian besar nilai yang ditentukan enumerasi WDF_FILE_INFORMATION_CLASS , file header wdm.h atau ntifs.h menentukan struktur bernama FILE_XXXX_INFORMATION yang dapat digunakan driver saat mendapatkan atau mengatur informasi file.

Untuk informasi selengkapnya tentang nilai enumerasi dan struktur terkait, lihat deskripsi parameter FileInformationClass dari ZwQueryInformationFile dan ZwSetInformationFile.
