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.
