Detailed Description

struct ieee80211_radiotap_iterator - tracks walk thru present radiotap args

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

Member Data Documentation

_arg_index

int ieee80211_radiotap_iterator::_arg_index

next argument index

_bitmap_shifter

uint32_t ieee80211_radiotap_iterator::_bitmap_shifter

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

_max_length

int ieee80211_radiotap_iterator::_max_length

length of radiotap header in cpu byte ordering

_next_bitmap

uint32_t* ieee80211_radiotap_iterator::_next_bitmap

internal pointer to next present u32

_next_ns_data

unsigned char * ieee80211_radiotap_iterator::_next_ns_data

beginning of the next namespace's data

_reset_on_ext

int ieee80211_radiotap_iterator::_reset_on_ext

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

_rtheader

struct ieee80211_radiotap_header* ieee80211_radiotap_iterator::_rtheader

pointer to the radiotap header we are walking through

_vns

const struct ieee80211_radiotap_vendor_namespaces* ieee80211_radiotap_iterator::_vns

vendor namespace definitions

current_namespace

const struct ieee80211_radiotap_namespace* ieee80211_radiotap_iterator::current_namespace

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

n_overrides

int ieee80211_radiotap_iterator::n_overrides

number of overrides

overrides

const struct radiotap_override* ieee80211_radiotap_iterator::overrides

override standard radiotap fields

this_arg

unsigned char* ieee80211_radiotap_iterator::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

int ieee80211_radiotap_iterator::this_arg_index

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

this_arg_size

int ieee80211_radiotap_iterator::this_arg_size

length of the current arg, for convenience
