# IXtfDeployCallback::OnDeployFileProgress

> IXtfDeployCallback::OnDeployFileProgress

# IXtfDeployCallback::OnDeployFileProgress

用于报告将文件部署到主机的进度的回调。

<a id="syntaxSection" />

## 语法

```cpp theme={null}
public:
HRESULT OnDeployFileProgress(
         LPCWSTR pszFilePath,
         ULONGLONG ullBytesTransferred,
         ULONGLONG ullFileSize
)  
```

<a id="parametersSection" />

### 参数

*pszFilePath*\
类型：LPCWSTR

正在部署的文件的路径。

*ullBytesTransferred*\
类型：ULONGLONG

到目前为止已传输的字节数。

*ullFileSize*\
类型：ULONGLONG

正在传输的文件的总大小（以字节为单位）。

<a id="retvalSection" />

### 返回值

类型：HRESULT

返回 `S_OK` 以继续部署，或返回 HRESULT 错误代码以取消部署。

<a id="remarksSection" />

## 备注

此回调在部署系统将文件从部署 PC 传输到主机时调用。每为一个文件成功传输一个缓冲区块，就会调用此回调一次。每个成功传输的文件至少调用两次此回调：一次在部署开始时，一次在部署结束时。如果部署一个长度为零的文件，两次调用都将报告已传输零个字节（共零个字节）。有关文件如何评估以及在部署过程中何时调用回调的详细信息，请参阅 [IXtfDeployCallback Interface](/reference/tools/xtf/xtfapplication/classes/IXtfDeployCallback/ixtfdeploycallback-xtfapplication-xbox-microsoft-t)。

<Note>部署的文件传输过程使用多个线程。你的代码必须确保按 `pszFilePath` 关联进度消息，并防范典型的多线程问题。</Note>

与 `IXtfDeployCallback` 的其他回调一样，如果此回调返回 `S_OK`，则部署过程继续。如果此回调返回任何 `HRESULT` 错误代码，则部署过程会立即取消。已传输或删除的文件保持原样，部分传输的文件将以其被截断的形式关闭。必须完成另一次部署，以确保主机上的所有文件完整且为最新。
