# XStoreQueryGameLicenseAsync

擷取為允許應用程式啟動而取得之授權的相關資訊。

## 語法

```cpp theme={null}
HRESULT XStoreQueryGameLicenseAsync(  
         const XStoreContextHandle storeContextHandle,  
         XAsyncBlock* async  
)  
```

### 參數

*storeContextHandle*   \_In\_\
類型：XStoreContextHandle

由 [XStoreCreateContext](https://docs.xbox.com/zh-TW/reference/system/xstore/functions/xstorecreatecontext.md) 傳回之使用者的商店內容控制代碼。

*async*   \_Inout\_\
類型：[XAsyncBlock\*](https://docs.xbox.com/zh-TW/reference/system/xasync/structs/xasyncblock.md)

定義正在進行之非同步工作的 [XAsyncBlock](https://docs.xbox.com/zh-TW/reference/system/xasync/structs/xasyncblock.md)。[XAsyncBlock](https://docs.xbox.com/zh-TW/reference/system/xasync/structs/xasyncblock.md) 可用來輪詢呼叫的狀態並擷取呼叫結果。如需詳細資訊，請參閱 [XAsyncBlock](https://docs.xbox.com/zh-TW/reference/system/xasync/structs/xasyncblock.md)。

### 傳回值

類型：HRESULT

HRESULT 成功或錯誤碼。

## 備註

若要擷取授權資訊以及此函式的執行結果，請在呼叫此函式之後呼叫 [XStoreQueryGameLicenseResult](https://docs.xbox.com/zh-TW/reference/system/xstore/functions/xstorequerygamelicenseresult.md)。[XStoreQueryGameLicenseResult](https://docs.xbox.com/zh-TW/reference/system/xstore/functions/xstorequerygamelicenseresult.md) 應在 **XStoreQueryGameLicenseAsync** 的回呼函式中呼叫。下列程式碼片段示範如何擷取為允許遊戲啟動而取得之授權的授權資訊。

```cpp theme={null}
void CALLBACK GameLicenseCallback(XAsyncBlock* asyncBlock)
{
    XStoreGameLicense result{};

    HRESULT hr = XStoreQueryGameLicenseResult(
        asyncBlock,
        &result);

    if (FAILED(hr))
    {
        printf("Failed retrieve the game license result: 0x%x\r\n", hr);
        return;
    }

    printf("expirationDate        : %d\r\n", result.expirationDate);
    printf("isActive              : %s\r\n", result.isActive ? "true" : "false");
    printf("isDiscLicense         : %s\r\n", result.isDiscLicense ? "true" : "false");
    printf("isTrial               : %s\r\n", result.isTrial ? "true" : "false");
    printf("isTrialOwnedByThisUser: %s\r\n", result.isTrialOwnedByThisUser ? "true" : "false");
    printf("skuStoreId            : %s\r\n", result.skuStoreId);
    printf("trialTimeRemaining    : %d\r\n", result.trialTimeRemainingInSeconds);
    printf("trialUniqueId         : %s\r\n", result.trialUniqueId);
}

void QueryGameLicense(XStoreContextHandle storeContextHandle, XTaskQueueHandle taskQueueHandle)
{
    auto asyncBlock = std::make_unique<XAsyncBlock>();
    ZeroMemory(asyncBlock.get(), sizeof(*asyncBlock));
    asyncBlock->queue = taskQueueHandle;
    asyncBlock->callback = GameLicenseCallback;

    HRESULT hr = XStoreQueryGameLicenseAsync(
        storeContextHandle,
        asyncBlock.get());

    if (FAILED(hr))
    {
        printf("Failed to get the game license: 0x%x\r\n", hr);
        return;
    }
}
```
