    In the function declaration, derefrence the desired parameter with the 'address of' operand (&).

    void myFunct(int &passedbyref, int notpassedbyref);
    Then, just use the variable inside the function as you always would.

    Not sure what you mean, perhaps something like this:

    Code:
    datatype *function (void)
    {
        datatype *variable;
    
        // do some stuff with the variable
    
        // return address of variable to main
        return variable;
    }
