# 获取 Title Storage 服务配置的配额信息

> 通过 XblTitleStorageGetQuotaAsync 检索 XBOX Title Storage 中指定服务配置和存储类型的配额及已用字节的扁平 C 代码示例。

本主题演示如何使用以下扁平 C 代码示例获取 XBOX Title Storage 中指定服务配置和存储类型的配额信息。

<Note>对于 `TrustedPlatform ` 存储类型,请求是针对调用玩家的 XBOX 用户 ID 发出的。</Note>

#### Flat C

```cpp theme={null}
auto asyncBlock = std::make_unique<XAsyncBlock>();
asyncBlock->queue = queue;
asyncBlock->context = nullptr;
asyncBlock->callback = [](XAsyncBlock* asyncBlock)
{
    std::unique_ptr<XAsyncBlock> asyncBlockPtr{ asyncBlock };   // Take over ownership of XAsyncBlock*.
    size_t usedBytes;
    size_t quotaBytes;
    HRESULT hr = XblTitleStorageGetQuotaResult(asyncBlock, &usedBytes, &quotaBytes);
};

HRESULT hr = XblTitleStorageGetQuotaAsync(
    xboxLiveContext,
    scid,
    storageType,
    asyncBlock.get()
);

if (SUCCEEDED(hr))
{
    // The call succeeded, so release  std::unique_ptr ownership of XAsyncBlock* because
    // the callback takes over ownership. If the call fails, however, std::unique_ptr keeps
    // ownership and deletes XAsyncBlock*.
    asyncBlock.release();
}
```
