In C I can do something like this
struct Point {
int x,y;
}
struct Circle {
struct Point p; // must be first!
int rad;
}
void move(struct Point *p,int dx,int dy) {
....
}
struct Circle c = .....;
move( (struct Point*)&c,1,2);
Using this approach, I can pass any struct(Circle,Rectangle,etc) that has struct Point as first member. How can I do the same in google go?
