You mean with pointer the dump_context::offset that is sort of a current
write location in dump_context::buf? Yes, that's the convention. But it
is something different that is happening:
Take dump_symbol. This first writes the Lisp_Symbol structure to the
dump. If appropriate, this is immediately followed by a
Lisp_Buffer_Local_Value that is written to the dump. The blv is not a
Lisp object.
Similar things are also done for hash tables, obarrays (I think) and
maybe others.
