wiphy_rfkill_start_polling(9)

📦 version 7.3.1, in nixpkgs unstable

💖 wiphy_rfkill_start_polling(9) 💖

okay so real talk, this is a page from the Kernel API Manual, and bestie, it's a short one — we love a low-effort icon. Let's get into it ✨

🌸 NAME 🌸

wiphy_rfkill_start_polling — literally just: start polling rfkill 🫶

🦋 SYNOPSIS 🦋

void wiphy_rfkill_start_polling (struct wiphy *wiphy );

that's it. that's the whole signature. no return value, no drama, she just does the thing 💅

🎀 ARGUMENTS 🎀

  • wiphy — the wiphy 👑 (yes bestie, that's the entire description the original gives us, iykyk — it's the wiphy)
ngl this page is giving "minimalist main character energy" — we're not even done yet, more parts are coming 🌈

🌈 SEE ALSO 🌈

okay bestie, this is the part where the manpage goes "here's everything else in the known universe" and honestly? it ate. it's giving reference section, it's giving lore, it's giving the entire cfg80211.h extended cinematic universe. grab a snack 🍓.

first up, the source file itself plus the OGs:

and that's the whole list bestie — every single reference, not one skipped, we do NOT leave lore on the table 💖

ngl if you read all of that you're genuinely built different. the (9) suffix just means "this is a kernel API manual page", so every one of these is one man away. iykyk 🌈

okay so the list literally keeps going — it's giving phone book but make it wifi 💀 — here's the rest of the SEE ALSO crew, every single one, no skips, no cap:

like, sixty-four whole cross-references bestie 😭 notice how a lot of them start with cfg80211_ and ieee80211_? that's not me being shady, that's just literally what's written here — the naming is giving main character energy and the prefixes are the whole personality 🌸 and yes, two of them are struct pages (struct cfg80211_ft_event_params(9) and struct cfg80211_mlo_reconf_done_data(9)) so don't come for me, they're listed with (9) same as everything else 💅

real talk though — this list is a reference list, so don't read it as "these all do X." each one has its own page for the details, iykyk 🫶

and that's the whole page, bestie, you made it to the end 🎀 this one lives way down in ./include/net, and the stamp on it says October 2026 — so if you're reading this in some other month, no you're not 🙈💜 go forth and rfkill-poll responsibly, mwah 💖✨🦋
