Its arguments argc - * and argv are the argument count and array as passed to the main() - * function on program invocation. An element of argv that starts with - * '-' is an option element. The characters of this element (aside from - * the initial '-') are option characters. If getopt() is called repeatedly, - * it returns successively each of the option characters from each of the - * option elements. - * - * If getopt() finds another option character, it returns that character, - * updating the external variable optind and a static variable nextchar so - * that the next call to getopt() can resume the scan with the following - * option character or argv-element. - * - * If there are no more option characters, getopt() returns -1. Then optind - * is the index in argv of the first argv-element that is not an option. - * - * The 'optstring' argument is a string containing the legitimate option - * characters. If such a character is followed by a colon, this indicates - * that the option requires an argument. If an argument is required for an - * option so getopt() places a pointer to the following text in the same - * argv-element, or the text of the following argv-element, in optarg. - * - * NOTES: - * 1. opterr is not supported and this implementation of getopt() never - * printfs error messages. - * 2. getopt is NOT threadsafe! - * 3. This version of getopt() does not reset global variables until - * -1 is returned. As a result, your command line parsing loops - * must call getopt() repeatedly and continue to parse if other - * errors are returned ('?' or ':') until getopt() finally returns -1. - * (You can also set optind to -1 to force a reset). - * - * Return: If an option was successfully found, then getopt() returns the - * option character. If all command-line options have been parsed, then - * getopt() returns -1. If getopt() encounters an option character that - * was not in optstring, then '?' is returned. If getopt() encounters an - * option with a missing argument, then the return value depends on the - * first character in optstring: if it is ':', then ':' is returned; - * otherwise '?' is returned. - * - ****************************************************************************/ - -int getopt(int argc, FAR char *const argv[], FAR const char *optstring) -{ - if (argv && optstring && argc > 1) - { - int noarg_ret = '?'; - char *optchar; - - /* The inital value of optind is 1.
