已知：.exe执行正确的话返回0，否则为非零。
用哪个函数调用它可以得到这个返回值，用以判断程序的执行情况。

试了下，command()是不行的，
比如：即使.exe是exit(-2)退出的，command()返回的还是0

自动驾驶传感器选型实战：摄像头、激光雷达与毫米波雷达融合策略自动驾驶感知系统的核心在于多传感器协同，而非单一技术优劣。摄像头擅长语义识别但受光照和天气制约；激光雷达提供高精度测距却面临成本、温漂与多径干扰等物理瓶颈；毫米波雷达则以全天候鲁棒性与精准测速成为安全底线的守门人。三者融合不是简单叠加，而是基于场景约束（如暴雨、强光、高速跟车）、成本边界（BOM控制）与时间窗口（量产节奏）的工程权衡。真实量产方案中，‘纯视觉’实为视觉主责+毫米波兜底，‘激光雷达上车’本质是用硬件真值加速算法迭代，而传统车企更倾向以毫米波为仲裁者协调冲突。理解这些底层原理，才能在传感器选型、阅读详情

更正一下：
原贴中command()应为system()
后来又验证了一下，system()是可以得到error code的，是我的程序有问题
各位的方法我也试了，可以用。
总结一下，结贴.
1. errorcode=system(command) //command: command line
2.
STARTUPINFO si;
PROCESS_INFORMATION pi;
char szAppPath[_MAX_PATH];

ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );

// Start the child process.
if( !CreateProcess( NULL, // No module name (use command line).
(LPSTR)(LPCTSTR)szAppPath,// Command line.
NULL, // Process handle not inheritable.
NULL, // Thread handle not inheritable.
FALSE, // Set handle inheritance to FALSE.
0, // No creation flags.
NULL, // Use parent's environment block.
NULL, // Use parent's starting directory.
&si, // Pointer to STARTUPINFO structure.
&pi ) // Pointer to PROCESS_INFORMATION structure.
)
{
fprintf(stderr,"Creat Process Error.\n" );
}

// Wait until child process exits.
WaitForSingleObject( pi.hProcess, INFINITE );

DWORD ExitCode = 0;
GetExitCodeProcess(pi.hProcess,&ExitCode);

//DeleteFile(szAppPath.GetAt(i));
// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );

GetExitCodeProcess

The GetExitCodeProcess function retrieves the termination status of the specified process.

BOOL GetExitCodeProcess(
HANDLE hProcess, // handle to the process
LPDWORD lpExitCode // termination status
);
Parameters
hProcess
[in] Handle to the process.
Windows NT/2000 or later: The handle must have PROCESS_QUERY_INFORMATION access. For more information, see Process Security and Access Rights.

lpExitCode
[out] Pointer to a variable to receive the process termination status.
Return Values
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.
