I just have a few general comments, that are minor, and yet important
(IMO).

I think the meaning of each field should be documented. A good
example you could look at, for instance, is the declaration of
type struct frame_id in frame.h.

I think it's important to also say WHAT the function does.
'Helper' doesn't help in that respect (no pun intended).

Empty line between variable declarations and code...
(sorry, one of the innumerable coding style rules in the GDB project).
