ieee80211_is_disassoc(9)

💫 ieee80211_is_disassoc — a Kernel API Manual moment 💫

okay so bestie, welcome to the Kernel API Manual ✨ this one's a tiny little helper living in the Linux kernel's wireless headers, and honestly? it's giving "small but iconic" 🎀

---

🌸 NAME 🌸

ieee80211_is_disassoc — check if IEEE80211_FTYPE_MGMT && IEEE80211_STYPE_DISASSOC 💅

like, that's literally the whole job. it checks whether a frame is a management frame and a disassociation subtype. no cap, that's it. 🦋

---

✨ SYNOPSIS ✨

bool ieee80211_is_disassoc (__le16 fc );

yes gorg, it takes the frame control bytes and returns a bool. short, sweet, slay. 👑

---

🫶 ARGUMENTS 🫶

• fc — the frame control bytes, in little-endian byteorder ⭐ (yes, little-endian, don't come for me, that's just how it is 💀)

---

💖 RETURN 💖

it hands you back whether or not the frame is a disassociation frame. that's the vibe check in question 🔥
