Uninitializes the Gaming Runtime.

Syntax

void XGameRuntimeUninitialize(  
)

Parameters

None.

Return value

Type: void

Remarks

To use the Gaming Runtime features in your game, first initialize the Gaming Runtime by invoking the XGameRuntimeInitialize function. When your game is done using the Gaming Runtime and is ready to exit, uninitialize the Gaming Runtime by invoking the XGameRuntimeUninitialize function. Invoke the XGameRuntimeUninitialize function as late as possible but before your game exits, typically within the entry-point function for your game.

The following example demonstrates how to use the XGameRuntimeInitialize and XGameRuntimeUninitialize functions within the entry-point function of a game that is based on the Direct3D 12 Desktop Game template in Visual Studio. The XGameRuntimeInitialize function is invoked before the Game object is instantiated and registered, and the XGameRuntimeUninitialize function is invoked after the Game object is reset but before the entry-point function returns.

// 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;
}
