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. AUTHOR
