Pointer Testing

Hello, Given a pointer value, is there some relatively trivial way to determine whether or not it points to a valid readable or writeable address? i.e. is there a way to find out whether accessing the address will cause a panic? I'm interested in how to do this from a KEXT, but it also seems like it would be a useful ability to have in user-space too.
