+ * \param string The format string to parse.
+ * \param params gengetopt parameters.
+ * \param admissible_uids The array of admissible uid ranges.
+ * \param fi The format info to be used with format_items().
+ *
+ * If \a string is not \p NULL, it is broken down into its components using
+ * \ref create_argv() and the resulting argument vector is passed together with
+ * \a params to gengetopt's command line parser. If --help or --detailed-help
+ * was specified in \a string, the corresponding help text is printed and the
+ * function returns zero.
+ *
+ * Otherwise, any --uid or --user options are parsed and transformed into an
+ * array of admissible uids which is returned via \a admissible_uids.
+ *
+ * Finally, the format string given by --format (or the default format string
+ * for the given select mode if no --format option was given in \a string) is
+ * parsed as well resulting in a format_info structure which is returned via
+ * \a fi. The caller uses the \a fi pointer later to format each output line.
+ *
+ * \return Negative on errors, zero if --help or --detailed-help was given,
+ * positive otherwise.
