# 从您的标题调用 wd 工具

> 从您的标题调用 wd 工具

本部分将提供在您的标题代码中调用主机上 wd 工具的详细信息和示例代码。例如,在标题代码中调用 wdtrace.exe 以启用网络跟踪来调试多人游戏延迟问题。

## 调用 wd 工具的标题示例代码

以下示例代码行详细介绍了启动 wdtrace 进程的辅助方法。在此示例中,可以用任何 wd 工具替换 wdtrace。第二个参数是启动该工具的参数。

```c++ theme={null}
CreateAndRunRedirectedStdoutProcess(L"C:\\Windows\\System32\\wdtrace.exe", const_cast<wchar_t*>(L" start advancedmp"));
```

以下是 CreateAndRunRedirectedStdoutProcess 方法用于 wdconfig.exe 的另一个示例。

```c++ theme={null}
CreateAndRunRedirectedStdoutProcess(L"C:\\Windows\\System32\\wdconfig.exe", const_cast<wchar_t*>(L" query consolemode"));
```

这是一段辅助代码示例,用于创建进程并将输出从 Stdout 重定向到 OutputDebugString。然后就能使输出显示在 Visual Studio 或 XbWatson 中。也可以将其替换为文件写入以将输出存储到文件中。

```c++ theme={null}
void
ReadAndHandleOutput(
    _In_ HANDLE hPipeRead)
{
    CHAR lpBuffer[256];
    DWORD nBytesRead;
    BOOL  result = TRUE;

    while (result)
    {
        ZeroMemory(lpBuffer, sizeof(lpBuffer));
        result = ReadFile(hPipeRead, lpBuffer, (sizeof(lpBuffer) - 1), &nBytesRead, NULL);
        if (!result || !nBytesRead)
        {
            if (GetLastError() == ERROR_BROKEN_PIPE)
            {
                break;
            }
            else
            {
                break;
            }
        }
        
        // Instead of outputting this via OutputDebugStringA, it could instead be written to a log file.
        
        try
        {
            OutputDebugStringA(lpBuffer);
        }
        catch (...)
        {
            return;
        }
    }
}
