tipc_setsockopt(9)

💅 tipc_setsockopt(9) — a lil' page from the Kernel API Manual

okay so bestie, welcome to the group chat. this is tipc_setsockopt, a kernel function, and honestly she's kind of a queen of doing the absolute least. let's get into it 💖

---

✨ NAME ✨

tipc_setsockopt — set socket option 🎀

like, she sets the socket option. that's the whole personality. iconic.

---

✨ SYNOPSIS ✨

int tipc_setsockopt (struct socket *sock , int lvl , int opt , sockptr_t
ov , unsigned int ol );

---

✨ ARGUMENTS ✨

listen bestie, the roster is small but every single one matters:

• sock — the socket structure itself 🫶 the main character of this whole situation
• lvl — the option level, aka which layer of the vibe we're talking to
• opt — the option identifier, the actual which option of it all
• ov — pointer to the new option value ✨ she points at the newness
• ol — length of the option value, so we know how much of it there is

---

✨ DESCRIPTION ✨

so here's the tea 🍓: this is for stream sockets only. and when you hit her with it, she accepts and ignores all IPPROTO_TCP options — the whole point is just to ease compatibility, no cap. she's not reading them, she's not judging them, she's just letting them through so everything plays nice 💅

---

✨ RETURN ✨

• 0 on success 🎉 slay
• errno otherwise 😭 it's giving not-her-day

🦋 friendly reminder bestie: she really does ignore those IPPROTO_TCP options on stream sockets. that's the documented behaviour, not me being shady. iykyk.

okay that's the page!! mwah 💋 this icon came to you from source ./net/tipc, dated October 2026 — bookmark her, she ate and left no crumbs 👑✨🌈
