ieee80211_op...s_to_chandef(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, you opened the ieee80211_op...s_to_chandef(9) page from the Kernel API Manual, and the main character here is ieee80211_operating_class_to_chandef 💅✨ — it's literally about converting an operating class to a chandef, no cap.

🌸 NAME 🌸

ieee80211_operating_class_to_chandef — convert operating class to chandef. that's the whole name, and it's giving exactly what it says on the tin 🎀

✨ SYNOPSIS ✨

here's the signature, copied with love and zero edits, bestie 🫶:

bool ieee80211_operating_class_to_chandef (u8 operating_class , struct
       ieee80211_channel *chan , struct cfg80211_chan_def *chandef );

💅 ARGUMENTS 💅

okay, the rundown:

  • operating_class — the operating class to convert. it's a u8 operating_class, iykyk 💜
  • chan — the ieee80211_channel to convert. (struct ieee80211_channel *chan 🌸)
  • chandef — a pointer to the resulting chandef. (struct cfg80211_chan_def *chandef 🦋)

🎀 RETURN 🎀

  • true — if the conversion was successful ✨
  • false — otherwise 💀

💜 SEE ALSO 💜

okay so this page has a lot of friends, and honestly? the cross-reference list is giving main character energy all on its own. every single one is here, bestie, nothing skipped — think of it as your reading list for the whole cfg80211 cinematic universe 🌈

first up, the literal source of truth:

  • Kernel file ./include/net/cfg80211.h

and the intro-level stuff you should probably meet before you go deeper:

  • Introduction(9), Device registration(9), Actions and configuration(9), Scanning and BSS list handling(9), Neighbor Awareness Networking (NAN)(9), Utility functions(9), Data path helpers(9), Regulatory enforcement infrastructure(9), Internal regulatory db functions(9), RFkill integration(9), Vendor commands(9), Test mode(9)

🍓 utility functions (the little helpers that ate)

🔥 data path helpers

🌈 regulatory enforcement + internal regdb

⭐ BSS notifications & mgmt frames

🫶 rfkill, vendor commands & test mode

👑 connect / roam / station + notification squad

and yes, that's genuinely every single one of them — no cap, not a single reference left behind 💅✨ lowkey each of these is a whole rabbit hole of its own, so pace yourself 🐇💖

…and the list just keeps going, bestie 😭 this SEE ALSO section is not playing around. Part two of the cross-refs, coming right up, no skips, no cuts 💅

And that's a wrap on the whole page, bestie 🫶 go read the actual man page in ./include/net on your system if you want the source-of-truth, and this one's dated October 2026 under the name ieee80211_op...s_to_chandef(9). Slay, you're done 💖✨🎀
