If I understand correctly, you will have no more than
19 x 19 lines, right? So,

(a) This is a small amount of memory per board,  either "reserved"
in the program text, or allocated on the stack during a run.

(b) if you are worried about objects of this type being passed
around costly, no need :-) The compiler will make a good decision
whether to use by copy or by reference, irrespective of the
parameter mode (in, out, in out).

Any particular reason why you want to use a pointer?
