The "->" is a shorthand reference for the long hand version:


It's more commonly used, kinda like the function pointer.  Hardly anyone
refers to the function points as...

        int get_size (int);
        int (*func) (int);

        func = get_size;

        (*func) (13);

They refer to it's shorthand:

        func (13);
