    if var is a private member of your class ( and i take it that keyword is just a placeholder) then thats fine. btw you sdont need the return; at the end of a function that returns void. Only if you are returning from the middle of the func do you need that. i.e.
    void func()
    {
    if(something) return;
    else
    {
    //do $$$$
    }
    }
    Free the weed!! Class B to class C is not good enough!!
    And the FAQ is here :- http://faq.cprogramming.com/cgi-bin/smartfaq.cgi

    That should work fine (did for me), just make a variable named var.
