get_wiphy_regdom(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 get_wiphy_regdom(9)

okay so welcome to the get_wiphy_regdom(9) page, bestie 💖 this is straight out of the Kernel API Manual and honestly it's a little nugget of a function but it's important, so let's give it the attention it deserves ✨

🌸 NAME 🌸

get_wiphy_regdom — get custom regdomain for the given wiphy 👑

like, it hands you back the custom regulatory domain that belongs to a wiphy. that's the whole vibe. no cap 🫶

✨ SYNOPSIS ✨

const struct ieee80211_regdomain * get_wiphy_regdom (struct wiphy *wiphy
);

ok so it takes exactly one thing and gives you back one thing, iconic behaviour honestly 🎀

🧚 ARGUMENTS 🧚

  • wiphy — the wiphy to get the regdomain from 🦋 this is literally the thing you're pulling the regulatory domain out of, so, y'know, you do gotta give it one

🔥 CONTEXT 🔥

Requires any of RTNL, wiphy mutex or RCU protection.

bestie please do not forget this part 😭 you need any of RTNL, the wiphy mutex, or RCU protection held when you call this. it's not optional, it's giving "locked door, you need a key" energy 💅 so pick your protection and hold it, fr fr

🌈 RETURN 🌈

pointer to the regulatory domain associated with the wiphy ⭐

so yeah, you get back a pointer to the regdomain that's tied to that wiphy — that's the whole gift 🎁 and it's a const struct ieee80211_regdomain *, so pls don't go trying to write through it, that's not the move 🙈

🌈 SEE ALSO 🌈

okay so this is the part where the page just... lists everyone. it's giving award-show seating chart, bestie — and honestly? iconic behavior. every single one of these is a real reference you can go pull up, so here's the full guest list in order, no cuts, no skips, fr fr 💅

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

that's home base — the file this whole page lives in — and literally everything under here comes straight out of it, so buckle up 🎀

not the capability structs showing up in full force — they ate, periodt ✨

the chandef girlies are literally carrying this section ngl 🦋

okay the wiphy cluster is lowkey the whole personality of the page, we're getting to the good stuff 🫶

queue, cancel, flush, pending — the work trio said copy paste slay, and honestly? valid 🌸

the find_elem / find_ie matching pairs are so synchronized, it's giving twin icons 💜

regulatory said "you will respect my authority" and honestly, fair 🧚

ref / put / unlink — the bss lifecycle trio, we see you 😭

and that's where this part of the list lands — deep in the notify-and-event corner of the group chat, which is lowkey everyone's favorite messy subsection 🙈

okay bestie, the SEE ALSO list does NOT stop, it just keeps going, and honestly? iconic behavior. here's the rest of the cross-references, in the exact order the page gives them, because we do not shuffle the sacred list 💅

like… that's sixty-four cross-refs, bestie. sixty-four!! no cap, that's a whole friend group 💀🫶

and that's a wrap on get_wiphy_regdom(9)!! you made it to the end of the whole page, which is genuinely a flex 🎀✨

little housekeeping for the record books: this page lives in the source tree at ./include/net, it's dated October 2026, and yes it's still the get_wiphy_regdom(9) page the whole way through. ship it, you ate 💅👑
