ieee80211_is_assoc(9)

💅 ieee80211_is_assoc(9)

okay so welcome to the Kernel API Manual, bestie — this is the page for ieee80211_is_assoc, and honestly? it's a lil one but it eats. 🍓

---

✨ NAME ✨

ieee80211_is_assoc — check if (Re)association request/response frame 🦋

like yes that's the whole job and she does it flawlessly, no notes.

---

🌸 SYNOPSIS 🌸

bool ieee80211_is_assoc(__le16 fc);

one function, one argument, returns a bool. minimal. clean. iconic. 👑

---

🎀 ARGUMENTS 🎀

• fc — frame control bytes in little-endian byteorder ✨ (yes little-endian, don't come at me, that's literally the spec)

fr fr the endianness matters, so pls don't just jam bytes in there and hope 💀

---

🔥 RETURN 🔥

she returns whether or not the frame is an (re)association request or response 💖 — that's it, that's the whole vibe check. true = yes bestie it's a (re)assoc req/resp, false = not it.
