How can I programmatically close all other applications from my iPhone application?

I am developing a test application to discover the capabilities of IOS system, so I would like to know if there is some way where I can get the list of all processes running on My DEVICE said it: Iphone, Ipad or Ipod. Then I would like to use the PID List or Proc开发者_如何转开发ess Id list to iterate over it and Kill them all, one by one but only certain processes specially those which were started by the user and aren't critical process of the system. I have found some example from XCODE documentation about how to kill processes running on MAC OS but nothing about IOS, I dont know the starting point to begin my searching, or what is the IOS framework I need to seek.

You can't, iOS doesn't allow you to access other applications at all.
