For this model I would opt to simply always return a status and pass
values, if any, though pointers. In programming it makes very little
difference: You'd end up storing the returned value anyway, because the
error return needs to be evaluated first.

I would happily make exceptions for all functions that cannot return
with an error, such as is_playing() and other accessors that can give a
meaningful result even if there is no meaningful input.
