Which is, pretty much, the exact opposite of passing it by value (one
might even term it "pass by reference"). If the called function
modifies the string you've passed in this way, it's changing your string
not its own copy.
Mind you, the meaning of "pass by value" *does* vary widely depending on
exactly which religion you subscribe to ...
