遅延コンテキストに対する DDI 関数の除外

このセクションは、Windows 7 以降、および Windows Server 2008 R2 以降のバージョンで Windows オペレーティング システムのみを対象としています。

Microsoft Direct3D ランタイムがユーザー モード表示ドライバーの CreateDeferredContext 関数を呼び出して遅延コンテキストを作成すると、ドライバーは、ランタイムがその遅延コンテキストに対して呼び出すことができる関数を提供します。 ドライバーは、D3D11DDIARG_CREATEDEFERREDCONTEXT 構造体の p11ContextFuncs メンバーが指す D3D11DDI_DEVICEFUNCS 構造体のメンバーを満たします。 ドライバーは、ドライバーが即時コンテキストに対して行うのと同様に、遅延コンテキストの関数のサブセットのみを提供します。

ドライバーは、D3D11_1DDI_DEVICEFUNCS または D3D11DDI_DEVICEFUNCS の次のメンバーを NULL に設定することで、遅延コンテキストの多くの関数を除外します。
