Unfortunately, "optind = 0 means initialize" seems to be a glibc
feature that is not backed up by POSIX. So I agree that gengetopt
should not rely on it. Which leaves the question how to tell getopt
to discard any internal pointers in a portable way.
I guess the right thing to do is to never free arguments passed to
getopt_long if another call has to be made: this seems to never be safe
(even because getopt_long can rearrange the elements, as documented).
I uploaded a newer version here
http://rap.dsi.unifi.it/~bettini/gengetopt-2.17rc.tar.gz
I still haven't documented the use of multiple parsers but there's the
test test_multiple_parsers that can be taken as an example of usage of
three parsers.
there's the new parser function that can be generated with the gengetopt
command line
-S, --string-parser generate a string parser (the string
contains the command line)
see the test test_multiple_parsers.c
Of course I switched back to optind = 1
I hope to hear from you soon about this new feature (before I release it)
thanks in advance
Lorenzo
