3. 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 namespaceAqs 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

4. 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.
