tipc_shutdown(9)

✨ NAME ✨

tipc_shutdown — shutdown socket connection 💅

okay so real quick bestie, before we even get into it: this is from the Kernel API Manual, section 9, and it's all about that one little function that ends a TIPC connection and clears the decks. stay with me, it's short and it slays 🫶

---

🌸 SYNOPSIS 🌸

int tipc_shutdown (struct socket *sock , int how );

like, that's the whole signature. two args, one int coming back at you. no cap, that's it 🎀

---

🦋 ARGUMENTS 🦋

• sock — the socket structure. your main character. this is the socket you're shutting down ✨
• how — the direction to close, and heads up: it must be SHUT_RDWR. not a suggestion, not a vibe, it just has to be that. 💀

---

💖 DESCRIPTION 💖

so what does it actually do? two things, in order:

1. It terminates the connection (if necessary — key phrase, if necessary, iykyk).
2. Then it purges the socket's receive queue.

that's the entire personality. connection ended, receive queue yeeted, done. 🌈

not me emphasizing that "if necessary" — but fr fr, the connection termination is conditional, the receive-queue purge is just what happens. don't @ me, that's literally the manpage.

---

👑 RETURN 👑

• 0 on success 🎉
• errno otherwise 😭

like, it's giving classic kernel return convention and honestly? iconic.

<aqua>okay that's the whole page, bestie, you ate that 🫶 this came out of the ./net/tipc corner of the kernel tree, dated October 2026, and it lives in section 9 of the Kernel API Manual — periodt. 💅✨</aqua>
