Función DxgkInitialize (dispmprt.h)

Artículo
05/23/2024

La función DxgkInitialize carga e inicializa el subsistema del kernel de gráficos de DirectX (Dxgkrnl.sys).

Sintaxis

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

Parámetros

[in] DriverObject

Puntero a una estructura de DRIVER_OBJECT . El controlador de miniporte de pantalla obtuvo anteriormente este puntero en su función DriverEntry .

[in] RegistryPath

Puntero a una estructura de UNICODE_STRING que proporciona la ruta de acceso a la clave del Registro del servicio del controlador. El controlador de minipuerto de pantalla obtuvo previamente este puntero en su función DRIVER_OBJECT .

[in] DriverInitializationData

Puntero a una estructura de DRIVER_INITIALIZATION_DATA que proporciona el subsistema del kernel de gráficos de DirectX con punteros a funciones implementadas por el controlador de minipuerto de pantalla.

Valor devuelto

DxgkInitializedevuelve STATUS_SUCCESS si se realiza correctamente; de lo contrario, devuelve uno de los códigos de error definidos en Ntstatus.h.

Comentarios

La función DriverEntry del controlador driver de pantalla llama a DxgkInitialize.

Ejemplos

En el ejemplo de código siguiente se muestra una implementación de DriverEntry en la que se llama a 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;
    }
