[help-gengetopt] restricting an array to 3 args

[BuildSmart]

I wish to first thank the authors of gengetopt for such a lovely  
peice of work as it has saved me countless hours of programming.

I'm trying to set the default values for an int array and to  
establish that it requires 3 args.

I've gone over the manual and I'm unable to find a solution to enter  
in the '.ggo' file which leaves me to do some manual editing.


I assigned the following in ggo file:
_______________________________

option  "font_color_selected"   - "RColor[0] of selected font  
text"          int                        default="51" no multiple
_______________________________


then I edited the cmdline1.c file and changed the following:
_______________________________

  else /* set the default value */
    {
      if (! args_info->font_color_selected_arg && ! args_info- 
>font_color_selected_given)
        {
          args_info->font_color_selected_arg = (int *) malloc  
(sizeof (int));
          args_info->font_color_selected_arg [0] = 51;
          args_info->font_color_selected_orig = (char **) malloc  
(sizeof (char *));
          args_info->font_color_selected_orig [0] = NULL;
        }
    }
_______________________________


to:
_______________________________

  else /* set the default value */
    {
      if (! args_info->font_color_selected_arg && ! args_info- 
>font_color_selected_given)
        {
          args_info->font_color_selected_arg = (int *) malloc  
(sizeof (int));
          args_info->font_color_selected_arg [0] = 51;
          args_info->font_color_selected_arg [1] = 51;
          args_info->font_color_selected_arg [2] = 51;
          args_info->font_color_selected_orig = (char **) malloc  
(sizeof (char *));
          args_info->font_color_selected_orig [0] = NULL;
          args_info->font_color_selected_orig [1] = NULL;
          args_info->font_color_selected_orig [2] = NULL;
        }
    }

The issue now is ensuring that 3 values are passed from the command  
line or config file and if the value is < or > 3 complain about it.
