-   ERR is the error code returned by one of the xstrto* functions.

-   Use OPT_IDX to decide whether to print the short option string "C"
-   or "-C" or a long option string derived from LONG_OPTIONS.  OPT_IDX
-   is -2 if the short option "C" was used, without any leading "-"; it
-   is -1 if the short option "-C" was used; otherwise it is an index
-   into LONG_OPTIONS, which should have a name preceded by two '-'
-   characters.
-
-   ARG is the option-argument containing the integer.
