cfg80211_iter_rnr(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, this is cfg80211_iter_rnr(9), straight out of the Kernel API Manual ✨ — part 1 of 3, by the way 👑. It's the helper that walks through frame elements, finds the RNR elements, and then checks out all their entries. no cap, that's the whole vibe 💅.

🌸 NAME 🌸

cfg80211_iter_rnr — iterate reduced neighbor report entries 🦋

✨ SYNOPSIS ✨

       bool cfg80211_iter_rnr (const u8 *elems , size_t elems_len , enum
       cfg80211_rnr_iter_ret (*iter)(void *data, u8 type, const struct
       ieee80211_neighbor_ap_info *info, const u8 *tbtt_info, u8 tbtt_info_len)
       , void *iter_data );

That signature is giving "lots of args" energy, but it's literally just the element blob, its length, your iteration function, and some extra data for that function 🫶.

🎀 ARGUMENTS 🎀

  • elems — the frame elements we're iterating RNR elements — and then their entries — in 🌈. like, that's the whole starting point, bestie.
  • elems_len — the length of the elements 💖. periodt.
  • iter — the iteration function 💅. also see enum cfg80211_rnr_iter_ret for what its return value means, iykyk.
  • iter_data — additional data that gets passed to the iteration function 🫶. literally just extra stuff for your function to use.

🔥 RETURN 🔥

Returns true on success 💖 — that means all entries got successfully iterated, or the iteration function returned RNR_ITER_BREAK 👑. Returns false on error 😭 — that happens if the iteration function returned RNR_ITER_ERROR, or if the elements were malformed. no cap, malformed elements are a no 💀.

✨ SEE ALSO ✨

okay bestie, this is the part where the manpage stops explaining and just drops the entire friend list. like every single page that's ever been in the group chat 💀 grab a snack, we're going through all of them. no skipping. i'm literally not letting you skip. 🍓
