Where the best place to question about feature

[Nilton Jose Rizzo]

Hi all

I'm have a quenstion about getopt_long functionality, where the best
place to send my question?


I'm trying use a getopt_long and get a fuzzy operation with 
an optional argument.

Look at git at gitlab.com:ufrrj/disciplinas/IC501.git
the source code are in src/C++  or src/C directory
getopt_long.{c,cpp}

when I run with this command line:

% clang getopt_long.c -o getopt_long
% ./getopt_long 
Retorno: 1 :
% ./getopt_long -h
Retorno: 0 :
% ./getopt_long -h d
Help: d :
Retorno: 1 :
% ./getopt_long --help
Segmentation fault (core dumped)
% ./getopt_long --help=
Help:   :
Retorno: 1 :
% 

My questions is How I detect correct when the optional argument
was passed or not


TIA
