📦 version 7.3.1, in nixpkgs unstable

💖 wiphy_register(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's called wiphy_register(9) and it's literally the glow-up moment for your wireless device. let's get into it 🎀

🌸 NAME 🌸

wiphy_register — register a wiphy with cfg80211 🦋

like, you made a whole wiphy. now introduce it to the world. slay 💅

✨ SYNOPSIS ✨

int wiphy_register (struct wiphy *wiphy );

that's it. one function, one pointer, big main character energy 👑

🫶 ARGUMENTS 🫶

  • wiphy — The wiphy to register. 🧚 that's your baby! the struct you've been building up this whole time. hand it over and let cfg80211 know she exists 💖

⭐ RETURN ⭐

you get back a non-negative wiphy index — yay, you're official, here's your number bestie 🎉

or a negative error code — 😭 which means something went wrong, no cap. check it, seriously, don't just ignore it 🙈

ngl the return value is doing double duty here: <pink>index ≥ 0</pink> = success, <red>index < 0</red> = error. vibe check your result before you celebrate 💀

part 1 out of 3, bestie — there's more coming, don't go anywhere 🌈

  • the kernel file it lives in: ./include/net/cfg80211.h — that's the source of truth, the mothership 💖
  • Introduction(9), Device registration(9) — start here if you're brand new, no cap
