Hello.
In getunwind.2 first:
otherwise, no data is copied, and the
call succeeds, returning the size that would be needed to store the unwind
data.
and second:
On success, getunwind returns the size of unwind table.
As I understand size of unwind data > size of unwind table.
What size really returned?

I think it should say "returns the size of the unwind data",
and I've made that change. Perhaps Marcela can confirm.
Cheers,
Michael
