increment_optind() sounds excellent! Thanks! > Oh, but you mentioned it doesn't currently even handle the middle > options (which is what I thought the point was for your getopt()?). I'm not sure what you mean by "middle options"... It currently behaves exactly like GNU getopt as far as required arguments (as in "o:") and non-option arguments (as in "-") except it doesn't permute[1] argv and optind doesn't work like GNU getopt. I don't use optional arguments (which I believe is a GNU extension) but I'll implement it if I knew how to use it :) And... I don't think there's anything else, is there??? Oh, my code does handle "--" :) > You'd still need > increment_optind()---or you could break getopt()'s parameter list by > passing back the allocated string (make sure it gets freed > somewhere...). My original version of getopt allocated an array that is the same size as argc+1, but I realized freeing it becomes a problem (don't wanna use atexit(), and wanna keep compatibility so don't wanna use a cleanup function call). I modified the program to not use allocation at all. > If you email me the code, I'd be happy to comment on it (comp.lang.c is > a hobby of mine, though one I haven't gotten around to lately).

Maybe I'll just put up a copy on my website. Thanks, Micah! -Mark [1] - Thank you for bringing up the proper vocabulary :) -- Mark K.
