cipso_v4_sock_delattr(9)

💖 cipso_v4_sock_delattr — the kernel API manual, bestie edition 💖

Okay so real talk, this one's from the kernel API manual (cipso_v4_sock_delattr(9)), and it's honestly so simple it's giving "one-line icon". Let's get into it 🎀

---

✨ NAME ✨

cipso_v4_sock_delattr — delete the CIPSO option from a socket. That's it, that's the whole job 💅

---

🌸 SYNOPSIS 🌸

void cipso_v4_sock_delattr (struct sock *sk );

Not me copy-pasting this exactly because you know I would never retype a signature from memory 😭

---

🦋 ARGUMENTS 🦋

• sk — the socket. Yeah, just the socket. That's the only thing you're handing over, no extra lore, no secret third argument, nothing 🫶

---

🔥 DESCRIPTION 🔥

Removes the CIPSO option from a socket — if present. That "if present" is doing a lot of heavy lifting ngl, so like… if there's nothing there, nothing happens. No drama, no error, no main character meltdown. It just quietly does its thing ✨

Lowkey the vibe check here: this is a delete function, so it's the "cleaning up your room before your mom gets home" of kernel calls. Understood the assignment 🧚

That's the whole page, bestie — mwah 💋
