DxgkInitialize 函数 （dispmprt.h）

内核模式显示微型端口驱动程序（KMD）DriverEntry 例程调用系统提供的 DxgkInitialize 函数来加载和初始化 DirectX 图形内核子系统（Dxgkrnl.sys）。

语法

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

参数

[in] DriverObject

指向 DRIVER_OBJECT 结构的指针。 当 OS 调用 KMD 的 DriverEntry 例程时，DriverObject 传递给 KMD。

[in] RegistryPath

指向提供驱动程序服务注册表项路径的 UNICODE_STRING 的指针。 当 OS 调用 KMD 的 DriverEntry 例程时，OS 会将 RegistryPath 传递给 KMD。

[in] DriverInitializationData

指向 DRIVER_INITIALIZATION_DATA 结构的指针，该结构提供 Dxgkrnl，其中包含 KMD 实现的函数的指针。

返回值

DxgkInitialize 如果成功，则返回STATUS_SUCCESS;否则，它将返回 Ntstatus.h中定义的错误代码之一。

言论

下面的代码示例演示 DriverEntry 的实现，其中调用了 dxgkInitialize 。

NTSTATUS
DriverEntry(
    IN PDRIVER_OBJECT DriverObject,
    IN PUNICODE_STRING RegistryPath
    )
{
    DRIVER_INITIALIZATION_DATA DriverInitializationData = {'\0'};

    PAGED_CODE();

    if (! ARGUMENT_PRESENT(DriverObject) ||
        ! ARGUMENT_PRESENT(RegistryPath))
    {
        return STATUS_INVALID_PARAMETER;
