calipso_sock_delattr(9)

💅 calipso_sock_delattr(9) — the Kernel API Manual, bestie edition 🎀

okay so this one lives in the Kernel API Manual (section 9, kernel-space girlies only 💖) and it's about yeeting a CALIPSO option off a socket. short page, but we're gonna slay it anyway ✨

---

🌸 NAME 🌸

calipso_sock_delattr — Deleting the CALIPSO option from a socket, no cap 🫶

---

🦋 SYNOPSIS 🦋

void calipso_sock_delattr (struct sock *sk );

that's it. that's the whole signature. void function, one arg, zero returns, very demure 💅

---

✨ ARGUMENTS ✨

• sk — the socket 👑 the actual struct sock * you're operating on, the main character of this whole operation.

---

🔥 DESCRIPTION 🔥

Removes the CALIPSO option from a socket, if present. literally that's it, that's the whole job 🎀 it peeks at whether the option is there, and if it is, it's gone. if it isn't — no drama, nothing happens, no error, nothing to worry about 💜

no return value to check, no errno to stress over, it just does the little delete and moves on with its life. icon behaviour, honestly 😭✨

literally the entire personality of this function is "removes it if present" — please don't read anything more into it, i'm not gonna make stuff up about internals i don't have receipts for 🙈
