Question

我与C++共同管理外部方案:

_wsystem(exec);

如果这一进程的运行时间超过零秒,我想杀死这一进程。我可以这样做。

p = subprocess.Popen(self.temp_exec, shell=True)

cur_time = 0.0

while cur_time < self.time_limit:
            if p.poll() != None:
                # Kill the process
                                    p.terminate()
                break
            time.sleep(0.1)
            cur_time += 0.1

C++中p.poll()和p.terminate()的备选案文是什么?

谢谢。

P.S. Solutions concerning WinAPI也受到欢迎。

Answer 1

There is a MS knowledge base entry describing how to cleanly terminate applications. Essentially if you just want to kill the process and don t care about potential side effects then you can just use TerminateProcess.

如果一个程序仍在运行,可核查的Windows 2008/6方法是。 GetExitCodeProcess。

Answer 2

如果你能够从本组织一级解决问题,而不是利用沙捞越。例如,可以研究

http://devel.ringlet.net/sysutils/timelimit/

或者,你检查了Sharma的资源模块:

Answer 3

I can only comment on Unix, since that s the platform I know best.

p.poll() becomes kill(pid, 0)
p.terminate() becomes kill(pid, SIGTERM)
