cfg80211_chandef_add_dbe(9)

📦 version 7.3.1, in nixpkgs unstable

💜 cfg80211_chandef_add_dbe — like, the whole vibe

okay so real talk, we're in the Kernel API Manual bestie, and this page is about cfg80211_chandef_add_dbe. she's a little function with a big job and honestly? she ate. let's get into it 🫶

✨ NAME ✨

cfg80211_chandef_add_dbe — literally parses DBE info and adds it to a chandef. that's it, that's the whole thing, no cap 💅

🌸 SYNOPSIS 🌸

int cfg80211_chandef_add_dbe (struct cfg80211_chan_def *chandef , const
       struct ieee80211_uhr_dbe_info *dbe );

look at her go 😭 two pointers, one int return, classic main-character energy. note that the signature is wrapped across two lines exactly like the original — we do not mess with the code in this house 🔥

🦋 ARGUMENTS 🦋

  • chandef — the chandef you're expanding, babe. that's the one getting the glow-up ✨
  • dbe — the DBE info itself. ⚠️ important: it must be size-checked if not NULL. like, do not skip the size check, this is not a drill, we are not being chaotic today 🫶
🎀 friendly reminder: dbe can be NULL, but if it isn't? size-check it first. the manpage said it, so we say it, periodt.

⭐ RETURN ⭐

  • 0 — success!! we love to see it, slay 💖
  • a negative error code — it went sideways, bestie. negative means not today 😭

that's part one, stay tuned for more 👑

🫶 SEE ALSO 🫶

okay so this is the part where the page just... lists everyone. it's giving awards-show red carpet ✨ — every struct, every enum, every function that has literally anything to do with this corner of cfg80211 is getting named, and honestly? they all ate. 💅

no skimming allowed, bestie — we're going through the whole squad in order, so hydrate first 🍓

the last little stretch (we're so close bestie 🌟):

and that's literally the entire extended family — every single name, no cap 🧚 and there's still more page to go so don't you dare close the tab —

…and the extended fam continues, because this list is long and we are not skipping a single one, bestie:

ok that's genuinely the whole list, no cap — every single one is in there, in order, nothing dropped 💅

the little footer moment 🫶

So this page lives over in ./include/net (that's the source bestie, it's a kernel-headers situation, you know the vibe ✨), and the date on it is October 2026 — yes, we're being that current, main character energy fr fr. And the page itself answers to the name cfg80211_chandef_add_dbe(9), which is also the version stamp at the bottom. That's the whole footer, slayed, ate, no crumbs 😭👑

Go forth and add those chandefs, queen 💖🦋
