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 ...
