DxgkInitialize function

-description

The DxgkInitialize function loads and initializes the DirectX graphics kernel subsystem (Dxgkrnl.sys).

-parameters

-param DriverObject [in]

A pointer to a DRIVER_OBJECT structure. The display miniport driver previously obtained this pointer in its DriverEntry function.

-param RegistryPath [in]

A pointer to a UNICODE_STRING structure that supplies the path to the driver's service registry key. The display miniport driver previously obtained this pointer in its DRIVER_OBJECT function.

-param DriverInitializationData [in]

A pointer to a DRIVER_INITIALIZATION_DATA structure that supplies the DirectX graphics kernel subsystem with pointers to functions implemented by the display miniport driver.

-returns

DxgkInitializereturns STATUS_SUCCESS if it succeeds; otherwise, it returns one of the error codes defined in Ntstatus.h.

-remarks

The display miniport driver's DriverEntry function calls DxgkInitialize.

Examples

The following code example shows an implementation of DriverEntry in which DxgkInitialize is called.

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;
    }
