how to send a "Ctrl+Break" to a subprocess via pid or handler


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.

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


Solution

  • Windows? Try this:

    import signal
    proc.send_signal(signal.SIGBREAK)
    

    If you meant a signal interrupt (kill -2)

    import signal
    proc.send_signal(signal.SIGINT)
