WDF_FILE_INFORMATION_CLASS列挙 (wdffileobject.h)

  • [アーティクル]

[警告: UMDF 2 は UMDF の最新バージョンであり、UMDF 1 よりも優先されます。 すべての新しい UMDF ドライバーは、UMDF 2 を使用して記述する必要があります。 UMDF 1 には新機能が追加されておらず、新しいバージョンのWindows 10では UMDF 1 のサポートが制限されています。 ユニバーサル Windows ドライバーでは UMDF 2 を使用する必要があります。 詳細については、「UMDF を使用したはじめに」を参照してください。

WDF_FILE_INFORMATION_CLASS列挙は、ドライバーが取得または設定できるファイル情報の種類を識別します。

注釈

WDF_FILE_INFORMATION_CLASS列挙は、IWDFIoRequest2::GetQueryInformationParameters への入力値として、および IWDFIoRequest2::GetSetInformationParameters からの出力値として使用されます。

WDF_FILE_INFORMATION_CLASS列挙体が定義するほとんどの値について、wdm.h または ntifs.h ヘッダー ファイルは、ドライバーがファイル情報を取得または設定するときに使用できるFILE_XXXX_INFORMATION名前付き構造体を定義します。

列挙値と関連する構造体の詳細については、ZwQueryInformationFile および ZwSetInformationFile の FileInformationClass パラメーターの説明を参照してください。
