tls_alert_recv(9)

💌 tls_alert_recv(9) — like, the whole deal

okay bestie, so this is a page from the Kernel API Manual and honestly? it's a little one, but she's important. this is tls_alert_recv — the function that literally just sits there and parses TLS Alert messages. that's the vibe. that's the whole vibe. 🎀

---

✨ NAME ✨

tls_alert_recv — parse TLS Alert messages 💅

like, it takes an incoming alert message and pulls the interesting bits out of it so the kernel knows what's going on. no cap.

---

🌸 SYNOPSIS 🌸

void tls_alert_recv (const struct sock *sk , const struct msghdr *msg ,
       u8 *level , u8 *description );

note the void up front — she doesn't return anything, she just does. 🦋

---

💖 ARGUMENTS 💖

• sk — the socket ✨ — it's there so you get the IP address information. that's literally its job, bestie, don't ask it for more.
• msg — the incoming message that's about to get parsed. this is the thing we're here for. 🔥
• level — OUT — out comes the TLS AlertLevel value. she writes it for you, you don't write it for her. 💅
• description — OUT — out comes the TLS AlertDescription value. same deal, it's an output, okay? 🫶

lowkey important: level and description are both marked OUT, meaning the function fills them in. don't go stuffing your own values in there first and expecting a good time. 😭
