What do you mean by retrieve? Get a list of member names? Names and
types? Offsets? At runtime? At compile time?
(I think the answer's no, in any case.)

Again, I'm not sure what you mean. Do you mean compute a checksum of
the values, or the layout, or something else? At runtime, or before
the program runs? Or after?

You can retrieve information on object layout from DWARF debugging info.
