NAME
       struct_ieee80211_radiotap_iterator - tracks walk thru present radiotap args

SYNOPSIS
       struct ieee80211_radiotap_iterator {
	 struct ieee80211_radiotap_header * _rtheader;
	 const struct ieee80211_radiotap_vendor_namespaces * _vns;
	 const struct ieee80211_radiotap_namespace * current_namespace;
	 unsigned char * _arg;
	 unsigned char * _next_ns_data;
	 __le32 * _next_bitmap;
	 unsigned char * this_arg;
	 int this_arg_index;
	 int this_arg_size;
	 int is_radiotap_ns;
	 int _max_length;
	 int _arg_index;
	 uint32_t _bitmap_shifter;
	 int _reset_on_ext;
       };

MEMBERS
       _rtheader
	   pointer to the radiotap header we are walking through

       _vns
	   vendor namespace definitions

       current_namespace
	   pointer to the current namespace definition (or internally NULL if the current namespace is unknown)

       _arg
	   next argument pointer

       _next_ns_data
	   beginning of the next namespace's data

       _next_bitmap
	   internal pointer to next present u32

       this_arg
	   pointer to current radiotap arg; it is valid after each call to ieee80211_radiotap_iterator_next but also after
	   ieee80211_radiotap_iterator_init where it will point to the beginning of the actual data portion

       this_arg_index
	   index of current arg, valid after each successful call to ieee80211_radiotap_iterator_next

       this_arg_size
	   length of the current arg, for convenience

       is_radiotap_ns
	   indicates whether the current namespace is the default radiotap namespace or not

       _max_length
	   length of radiotap header in cpu byte ordering

       _arg_index
	   next argument index

       _bitmap_shifter
	   internal shifter for curr u32 bitmap, b0 set == arg present

       _reset_on_ext
	   internal; reset the arg index to 0 when going to the next bitmap word

DESCRIPTION
       Describes the radiotap parser state. Fields prefixed with an underscore must not be used by users of the parser, only by the parser
       internally.
