如何发送"Ctrl + Break"通过pid或处理程序进入子流程

问题描述

import subprocess

proc = subprocess.Popen(['c:\windows\system32\ping.exe','127.0.0.1', '-t'],stdout=subprocess.PIPE) 
while True: 
  line = proc.stdout.readline() 
  print "ping result:", line.rstrip() 
  #sendkey("Ctrl+Break", proc)            # i need this here, this is not for terminate the process but to print a statistics result for the ping result.

如果有人知道该怎么做，请与我分享，谢谢！

If someone know how to do it, please share with me, thanks!

推荐答案

Windows?试试这个:

Windows? Try this:

import signal
proc.send_signal(signal.SIGBREAK)

如果您要中断信号( kill -2 )

import signal
proc.send_signal(signal.SIGINT)
