# XPackageInstallChunksResult

检索 [XPackageInstallChunksAsync](/reference/system/xpackage/functions/xpackageinstallchunksasync) 调用的结果。

## 语法

```cpp theme={null}
HRESULT XPackageInstallChunksResult(  
         XAsyncBlock* asyncBlock,  
         XPackageInstallationMonitorHandle* installationMonitor  
)  
```

### 参数

*asyncBlock*   \_Inout\_\
类型：[XAsyncBlock\*](/reference/system/xasync/structs/xasyncblock)

传递给 [XPackageInstallChunksAsync](/reference/system/xpackage/functions/xpackageinstallchunksasync) 的 **XAsyncBlock**。

*installationMonitor*   \_Out\_\
类型：XPackageInstallationMonitorHandle\*

返回时，包含用于该安装的安装监视器。

### 返回值

类型：HRESULT

HRESULT 成功或错误代码。

## 备注

[XPackageInstallChunks](/reference/system/xpackage/functions/xpackageinstallchunks) 有一个异步变体。区块的安装可能需要提示用户接受下载大小。

此示例展示了如何使用异步 API 安装 BigMaps：

```cpp theme={null}
void CALLBACK BigMapsInstallProgress(
    void* /* context */,
    XPackageInstallationMonitorHandle monitor)
{
    XPackageInstallationProgress progress;
    XPackageGetInstallationProgress(monitor, &progress);
    if (progress.completed)
    {
        printf("BigMaps Installed\n");
        XPackageCloseInstallationMonitorHandle(monitor);
    }
}

void CALLBACK BigMapsAsyncInstallComplete(XAsyncBlock* asyncBlock)
{
    XPackageInstallationMonitorHandle monitor;
    HRESULT hr = XPackageInstallChunksResult(asyncBlock, &monitor);
    delete asyncBlock;

    if (SUCCEEDED(hr))
    {
        XTaskQueueRegistrationToken token;
        if (FAILED(XPackageRegisterInstallationProgressChanged(
            monitor,
            nullptr,
            BigMapsInstallProgress, &token)))
        {
            XPackageCloseInstallationMonitorHandle(monitor);
        }
    }
}

HRESULT InstallBigMapsAsync(XTaskQueueHandle queue)
{
    char id[XPACKAGE_IDENTIFIER_MAX_LENGTH];
    HRESULT hr = XPackageGetCurrentProcessPackageIdentifier(_countof(id), id);
    if (FAILED(hr)) return hr;

    XPackageChunkSelector selector;
    selector.type = XPackageChunkSelectorType::Tag;
    selector.tag = "BigMaps";

    XAsyncBlock* asyncBlock = new (std::nothrow) XAsyncBlock{};
    asyncBlock->callback = BigMapsAsyncInstallComplete;
    asyncBlock->queue = queue;

    hr = XPackageInstallChunksAsync(
        id, 1, &selector, 1000,
        false, asyncBlock);

    if (FAILED(hr))
    {
        delete asyncBlock;
    }

    return hr;
}
```

## 要求

**头文件：** XPackage.h

**库：** xgameruntime.lib

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