问题描述

这已经被问过,但我无法找到一个明确的答案,在code。

This has been asked before but I can't find a definitive answer, in code.

我打开一个过程,ProcessA(带PID 1234)。这一过程将打开一个子进程,ProcessAB(PID 5678)。
我做完了后,我终止ProcessA但我仍然有ProcessAB的缠绵。

I open a process, ProcessA (with PID 1234). This process opens a child process, ProcessAB (PID 5678).After I'm done I terminate ProcessA but I still have the lingering of ProcessAB.

我如何终止整个进程树?我的意思是,我如何确保我是否终止该进程,我打开我也终止所有相关的流程?

How do I terminate the whole process tree? What I mean, how do I make sure that if I terminate the process I opened I am also terminating all the associated processes?

感谢

code是AP preciated。

Code is appreciated.

推荐答案

检查this螺纹 的工作中分组的过程。

Check this thread for grouping processes within a "job".

如果不为你工作,一个土生土长的做法可能会去如下:

If that does not work for you, a home grown approach might go as follows:


  1. 让你的主进程ID

  2. 呼叫CreateToolhelp32Snapshot到enumerateall系统上的程序

  3. 检查PROCESSENTRY32结构的th32ParentProcessID成员上的每个进程,如果你的父母ID匹配,则终止该进程(使用TerminateProcess)

  4. 所有的孩子都结束后,终止主要工艺

样code:

    DWORD myprocID = 1234; // your main process id

PROCESSENTRY32 pe;

memset(&pe, 0, sizeof(PROCESSENTRY32));
pe.dwSize = sizeof(PROCESSENTRY32);

HANDLE hSnap = :: CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);

if (::Process32First(hSnap, &pe))
{
    BOOL bContinue = TRUE;

    // kill child processes
    while (bContinue)
    {
        // only kill child processes
        if (pe.th32ParentProcessID == myprocID)
        {
            HANDLE hChildProc = ::OpenProcess(PROCESS_ALL_ACCESS, FALSE, pe.th32ProcessID);

            if (hChildProc)
            {
                ::TerminateProcess(hChildProc, 1);
                ::CloseHandle(hChildProc);
            }
        }

        bContinue = ::Process32Next(hSnap, &pe);
    }

    // kill the main process
    HANDLE hProc = ::OpenProcess(PROCESS_ALL_ACCESS, FALSE, myprocID);

    if (hProc)
    {
        ::TerminateProcess(hProc, 1);
        ::CloseHandle(hProc);
    }
}
