sock_recvmsg(9)

💌 sock_recvmsg(9) — from the Kernel API Manual, bestie 💌

okay so picture this: it's a kernel API manual page, it's called sock_recvmsg(9), and it's literally about catching messages on a socket. i got you. let's go 🫶

---

✨ NAME ✨

sock_recvmsg — receive a message from @sock 💅 (yes the @ is in the original, it's giving very "i'm addressing the socket directly")

---

🌸 SYNOPSIS 🌸

int sock_recvmsg (struct socket *sock , struct msghdr *msg , int flags
);

three args, one int out, no cap. 🎀

---

🦋 ARGUMENTS 🦋

• sock — socket 💖
• msg — message to receive 🌸
• flags — message flags ⭐

that's the whole lineup, bestie. no hidden extras, i checked.

---

🔥 DESCRIPTION 🔥

so what it does: it receives msg from sock, passing through LSM. 👑

and what it gives back? the total number of bytes received, or an error. that's it. that's the whole vibe check. 💀

lowkey important: "or an error" is doing a LOT of work in that sentence — always check your return value, bestie, don't just assume the bytes arrived. 🙈
