pipapo_maybe_clone(9)

💅 pipapo_maybe_clone — kernel API manual, but make it make sense 🫶

okay so bestie, you're reading the page for pipapo_maybe_clone, and it lives in the kernel API manual section 9 (that's the kernel-internals girlies, not your regular command-line girlies). sit down, hydrate, and let's get into it ✨

---

✨ NAME ✨

pipapo_maybe_clone — build a clone for pending data changes, if one doesn't already exist. that's it, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

struct nft_pipapo_match * pipapo_maybe_clone (const struct nft_set *set);

---

🦋 ARGUMENTS 🦋

• set — the nftables API set representation. yep, that's the whole argument, she's low-maintenance 💅

---

⭐ RETURN ⭐

you get back the newly created clone or the existing clone, if there is any. and if allocation fails? you get NULL. no cap, that's the failure path, so check it 👑

fr fr do not just assume you got a pointer back — NULL on allocation failure is real and she will not be gentle about it 😭
