ieee80211_is_auth(9)

💅 ieee80211_is_auth — Kernel API Manual ✨

okay so bestie, we are in the 9 section today (that's the kernel API manual, iykyk), and this little cutie is called ieee80211_is_auth.

🌸 NAME 🌸

ieee80211_is_auth — check if IEEE80211_FTYPE_MGMT && IEEE80211_STYPE_AUTH

✨ SYNOPSIS ✨

bool ieee80211_is_auth (__le16 fc );

🎀 ARGUMENTS 🎀

• fc — frame control bytes in little-endian byteorder. yes, the raw little-endian bytes, no cap 🫶

🦋 RETURN 🦋

whether or not the frame is an authentication frame 💖 (that's literally it — a bool, she answers true or false, periodt)

honestly iconic company, she keeps good people around her 👑

ngl the whole vibe of this one is "tiny function, giant social circle" — read the friends too, they're all valid 💀

okay that's the page!! this gem lives over in ./include/linux and the vibe-check timestamp on it is October 2026 🌈 — go forth and check your frame control bytes, bestie, you're gonna slay 💅✨
