# XGameRuntimeUninitialize

> XGameRuntimeUninitialize

# XGameRuntimeUninitialize

取消初始化 Gaming Runtime。

## Syntax

```cpp theme={null}
void XGameRuntimeUninitialize(  
)  
```

### Parameters

无。

### Return value

类型：void

## Remarks

若要在游戏中使用 Gaming Runtime 功能，请先通过调用 [XGameRuntimeInitialize](/reference/system/xgameruntimeinit/functions/xgameruntimeinitialize) 函数来初始化 Gaming Runtime。当你的游戏完成对 Gaming Runtime 的使用并准备退出时，请通过调用 **XGameRuntimeUninitialize** 函数来取消初始化 Gaming Runtime。请尽可能晚地（但需在游戏退出之前）调用 **XGameRuntimeUninitialize** 函数，通常在游戏的入口点函数中调用。

以下示例演示了如何在基于 Visual Studio 中 **Direct3D 12 Desktop Game** 模板的游戏的入口点函数中使用 [XGameRuntimeInitialize](/reference/system/xgameruntimeinit/functions/xgameruntimeinitialize) 和 **XGameRuntimeUninitialize** 函数。在实例化并注册 **Game** 对象之前调用 **XGameRuntimeInitialize** 函数，并在重置 **Game** 对象之后但在入口点函数返回之前调用 **XGameRuntimeUninitialize** 函数。

```cpp theme={null}
// Entry point
int WINAPI wWinMain(_In_ HINSTANCE hInstance, _In_opt_ HINSTANCE hPrevInstance, _In_ LPWSTR lpCmdLine, _In_ int nCmdShow)
{
    UNREFERENCED_PARAMETER(hPrevInstance);
    UNREFERENCED_PARAMETER(lpCmdLine);

    // Initialize the Gaming Runtime before
    // performing any other activity.
    if (FAILED(XGameRuntimeInitialize()))
        return 1;

    if (!XMVerifyCPUSupport())
        return 1;

    g_game = std::make_unique<Game>();

    // Register class and create window
    {
        // Code omitted for brevity.
        ...
    }

    // Main message loop
    MSG msg = {};
    while (WM_QUIT != msg.message)
    {
        // Code omitted for brevity.
        ...
    }

    g_game.reset();

    // Uninitialize the Gaming Runtime after
    // all other activity has been completed.
    XGameRuntimeUninitialize();

    return (int) msg.wParam;
}
```

## Requirements

**头文件：** XGameRuntimeInit.h

**库：** xgameruntime.lib

**受支持的平台：** Windows、XBOX One 系列主机和 XBOX Series 主机
