# 从 Title Storage 删除 blob

> 扁平 C 代码示例，演示如何使用 XblTitleStorageDeleteBlobAsync 从 XBOX 服务 Title Storage 中删除 blob，并支持 ETag 匹配以用于云存档。

本主题通过以下扁平 C 代码示例演示如何从 XBOX 服务 Title Storage 中删除 blob。

#### 扁平 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*.
    HRESULT hr = XAsyncGetStatus(asyncBlock, false);
};

HRESULT hr = XblTitleStorageDeleteBlobAsync(
    xboxLiveContext,
    blobMetadata,
    deleteOnlyIfEtagMatches,
    asyncBlock.get()
);

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