💅 llc_qualify_conn_ev(9) — Kernel API Manual 🎀

okay bestie, welcome to the Kernel API Manual ✨ today we're decoding llc_qualify_conn_ev(9) and honestly? it's giving "small function, big main character energy." let's go 💖

---

✨ NAME ✨

llc_qualify_conn_ev — finds transition for event 🌸

like, it literally goes looking for the transition that matches what just happened. no cap.

---

🦋 SYNOPSIS 🦋

const struct llc_conn_state_trans * llc_qualify_conn_ev (struct sock *sk
, struct sk_buff *skb );

so it hands you back a const struct llc_conn_state_trans * — that's the whole vibe 🫶

---

🎀 ARGUMENTS 🎀

• sk — connection 💫 (this is the connection, she's the context, she's the moment)
• skb — happened event ⭐ (yep, the event that just went down)

---

🔥 DESCRIPTION 🔥

so what does it do? this function finds the transition that matches with the happened event. that's it, that's the whole job, and she does it flawlessly 💅

• on success → returns a pointer to the found transition ✨
• otherwise → returns NULL 💀

bestie pls check for NULL, it's literally the "otherwise" case and she will not warn you, she'll just hand you nothing and vibe away 🙈
