Sorry, this was badly worded.  Checking the return value is required
to ensure that snprintf() wrote all the data (rc < size, NOT <= size),
assuming you want that.  If you actually want it to silently truncate,
which you may if for example you're formatting the index, then you can
ignore it.  That may or may not cause an error if compiled with -Wall
-Werror flags... the glibc folks have been doing a lot of that lately.
