Can I pass an explicit cursor to a function/procedure for use in FOR loop?

Question

I have a procedure that performs some calculations on all records returned by a cursor. It looks a bit like this:

PROCEDURE do_calc(id table.id_column%TYPE)

Try this one, Usong ref cursor.

    declare
    type c is ref cursor;
    c2 c;
    type rec is record(
    id number,
    name varchar(20)
    );
    r rec;
    procedure p1(c1 in out c,r1 in out rec)is begin

    loop
    fetch c1 into r1;
    exit when c1%notfound;
    dbms_output.put_line(r1.id || ' ' ||r1.name);
    end loop;
    end;
    begin
    open c2 for select id, name from student;
    p1(c2,r);
    end;
