Please have a look at the code below, I am trying to redirect the output of
cmd.exe to a TMemo.

   HANDLE HNDChildStdoutRd, HNDChildStdoutWr, HNDChildStdinRd,
HNDChildStdinWr;

    SECURITY_ATTRIBUTES saAttr;
    saAttr.nLength= sizeof(SECURITY_ATTRIBUTES);
    saAttr.bInheritHandle = TRUE;
    saAttr.lpSecurityDescriptor = NULL;

    if (!CreatePipe(&HNDChildStdoutRd, &HNDChildStdoutWr, &saAttr, 0))
        PrintError("Stdout pipe creation failed.");

    if (!CreatePipe(&HNDChildStdinRd, &HNDChildStdinWr, &saAttr, 0))
        PrintError("Stdin pipe creation failed.");

    PROCESS_INFORMATION piProcInfo;
    STARTUPINFO siStartInfo;

    ZeroMemory(&piProcInfo, sizeof(PROCESS_INFORMATION));
    ZeroMemory(&siStartInfo, sizeof(STARTUPINFO));

    siStartInfo.cb = sizeof(STARTUPINFO);
    siStartInfo.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
    siStartInfo.wShowWindow = SW_SHOW;
    siStartInfo.hStdOutput = HNDChildStdoutWr;
    siStartInfo.hStdInput = GetStdHandle(STD_INPUT_HANDLE);
    siStartInfo.hStdError = GetStdHandle(STD_ERROR_HANDLE);

    if (!CreateProcess("C:\\Windows\\System32\\Cmd.exe", NULL, NULL, NULL,
TRUE, CREATE_NEW_CONSOLE, NULL, NULL, &siStartInfo, &piProcInfo))
        PrintError("Process creation failed.");


It works fine but the problem is ReadFile(HNDChildStdoutRd, ......) does not
return when I close cmd.exe, how do I make it return with error when cmd.exe
is closed so that it does not make my program stopped responding ?
