663 * parse_freqchan - Parse frequency or channel definition
665 * @chandef: chandef structure to be filled in
666 * @chan: Boolean whether to parse a channel or frequency based specifier
667 * @argc: Number of arguments
668 * @argv: Array of string arguments
669 * @parsed: Pointer to return the number of used arguments, or NULL to error
670 * out if any argument is left unused.
672 * The given chandef structure will be filled in from the command line
673 * arguments. argc/argv will be updated so that further arguments from the
674 * command line can be parsed.
676 * Note that despite the fact that the function knows how many center freqs
677 * are needed, there's an ambiguity if the next argument after this is an
678 * integer argument, since the valid channel width values are interpreted
679 * as such, rather than a following argument. This can be avoided by the
680 * user by giving "NOHT" instead.
682 * The working specifier if chan is set are:
683 * <channel> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz]
685 * And if frequency is set:
686 * <freq> [NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz]
687 * <control freq> [5|10|20|40|80|80+80|160] [<center1_freq> [<center2_freq>]]
689 * If the mode/channel width is not given the NOHT is assumed.
691 * Return: Number of used arguments, zero or negative error number otherwise
