Re: automatic struct-variable question

Here's the answer.  A bigdatum doesn't contain a pointer-to-char, as
if I had written
  char *id;
in the struct definition.  Rather, it contains a complete array of 200
chars.  In the original version of indexToId, x contains a copy of
those 200 chars.  So yes,
  char *result = x.id;
makes result point to the copy.
