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

Overview
