dxgkInitialize 函式 (dispmprt.h)

發行項
05/23/2024

DxgkInitialize 函式會載入並初始化 DirectX 圖形核心子系統 (Dxgkrnl.sys) 。

語法

NTSTATUS DxgkInitialize(
  [in] PDRIVER_OBJECT              DriverObject,
  [in] PUNICODE_STRING             RegistryPath,
  [in] PDRIVER_INITIALIZATION_DATA DriverInitializationData
);

參數

[in] DriverObject

DRIVER_OBJECT 結構的指標。顯示迷你埠驅動程式先前在其 DriverEntry 函式中取得此指標。

[in] RegistryPath

提供驅動程式服務登錄機碼路徑之UNICODE_STRING 結構的指標。顯示迷你埠驅動程式先前在其 DRIVER_OBJECT 函式中取得此指標。

[in] DriverInitializationData

DRIVER_INITIALIZATION_DATA 結構的指標，提供 DirectX 圖形核心子系統，以及顯示迷你埠驅動程式所實作之函式的指標。

傳回值

如果成功，DxgkInitialize會傳回STATUS_SUCCESS;否則，它會傳回 Ntstatus.h 中定義的其中一個錯誤碼。

備註

顯示迷你埠驅動程式的 DriverEntry 函式會呼叫 DxgkInitialize。

範例

下列程式代碼範例示範 DriverEntry 的實作，其中 會呼叫 DxgkInitialize 。

    IN PDRIVER_OBJECT DriverObject,
    IN PUNICODE_STRING RegistryPath
    )
