Your comment brings to mind another issue I had.  I was trying to fetch a
signed integer 32 variable that contained error codes.  But I was getting
large negative numbers.  I only got reasonable results when I set the cffi
code to look for an unsigned integer 32 variable.  Maybe the two issues are
related.
