[Twisted-Python] Killing a process
Hi, I wondered last time what is the best way under Win32 to kill a process launched with: reactor.spawnProcess() os.kill() as documented here: http://docs.python.org/lib/os-process.html#l2h-1676 only works under Macintosh and Unix. Furthermore, spawnProcess() doesn't return any handle, process ID or anything to deal with. Any help or idea would be really appreciated, Igor.

spawnProcess returns an IProcessTransport, which has a signalProcess method, which you can pass 'KILL' to end the process. Process termination with Twisted on Windows is unreliable, though, so whether or not it will work in your specific case is uncertain. Jean-Paul

I don't think that is true. TerminateProcess works fine to kill a single process. What isn't supported is killing a processes group, or asking a process politely to quit. On Aug 17, 2006, at 11:40 AM, Manlio Perillo wrote:

It uses an hack (create a thread on the remote process) but it seems to work fine, at least with Python process and Twisted.
That shouldn't be necessary if you just want to kill dead the process. James

Observations disagree. Jean-Paul
