Use ref or pointer, whatever suits you best.  Usually ref is preferable 
because it makes no difference at the call site:

void func(ref S s){
..
}

void main (){
S t;
func(t);  // only a pointer is actually passed
..
}

If you use a pointer though, you must explicitly pass an address of your 
struct:

void func(S* s){
..
}

void main (){
S t;
func(&t); // explicit address expression
..
}
