Killing a Process

[music-cat-bread]

Hi. I know this isn's a issue, but how I am supossed to kill a process or add something like daemon flag that is used in threads?

And here is more detailed reason. I am making a mobile app, and there will be a process that work in background and communicate with server, and it can not be a thread because then GUI can easily be broken. And a lot of times process will be stuck on .recv() from a socket library and it don't have a way to stop until:

• Server will went down. (it will not happen obviously)
• Something will kill it. (and this is what I want)

Thanks!
