C++里怎么利用代码连续执行cmd命令
我现在会先使用一行代码⼊telnet 设备IP进入一个交互界面。交互命令里去执行命令，就想mysql里进入mysql>这样的去执行命令并获取结果
大概是telnet 127.0.0.1
root>do jsona
获取结果
root>da jsonb
获取结果
我现在完成了利用管道获取一次结果。
BOOL PipeCmd(char *pszCmd, char *pszResultBuffer, DWORD dwResultBufferSize)
{
HANDLE hReadPipe = NULL;
HANDLE hWritePipe = NULL;
SECURITY_ATTRIBUTES securityAttributes = { 0 };
BOOL bRet = FALSE;
STARTUPINFO si = { 0 };
PROCESS_INFORMATION pi = { 0 };
// 设定管道的安全属性
securityAttributes.bInheritHandle = TRUE;
securityAttributes.nLength = sizeof(securityAttributes);
securityAttributes.lpSecurityDescriptor = NULL;
// 创建匿名管道
bRet = ::CreatePipe(&hReadPipe, &hWritePipe, &securityAttributes, 0);
if (FALSE == bRet)
{
ShowError("CreatePipe");
return FALSE;
}
// 设置新进程参数
si.cb = sizeof(si);
si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
si.wShowWindow = SW_HIDE;
si.hStdError = hWritePipe;
si.hStdOutput = hWritePipe;
// 创建新进程执行命令, 将执行结果写入匿名管道中
bRet = ::CreateProcess(NULL, pszCmd, NULL, NULL, TRUE, 0, NULL, NULL, &si, &pi);
if (bRet == FALSE)
{
ShowError("CreateProcess");
}
// 等待命令执行结束
::WaitForSingleObject(pi.hThread, INFINITE);
::WaitForSingleObject(pi.hProcess, INFINITE);
// 从匿名管道中读取结果到输出缓冲区
::RtlZeroMemory(pszResultBuffer, dwResultBufferSize);
::ReadFile(hReadPipe, pszResultBuffer, dwResultBufferSize, NULL, NULL);
// 关闭句柄, 释放内存
::CloseHandle(pi.hThread);
::CloseHandle(pi.hProcess);
::CloseHandle(hWritePipe);
::CloseHandle(hReadPipe);
return TRUE;
}
