It depends on what you mean. If you want to actually stop the process and restart it, then no you can't. At least not without starting another process that respawns the original. Some process that you write has to be running to relaunch the process. If you are wanting to "shut down" the process from the user's perspective and an operation perspective, that's pretty simple. Just call QuitUserInterface() and setup your main to relaunch the UI later or when some event occurs. Also, if you have continuous functions going on, then just have them checking a flag and go to sleep.
I'm not sure if that was what you were wanting, but I hope that helps.
