💅 nft_register_obj(9) — like, the Kernel API Manual tea 🍓

okay so bestie, welcome to nft_register_obj(9), straight out of the Kernel API Manual and honestly? it's giving "tiny function, big responsibilities" ✨

---

🌸 NAME 🌸

nft_register_obj — the girl whose whole job is registering a stateful object type for nf_tables 💖

---

✨ SYNOPSIS ✨

int nft_register_obj (struct nft_object_type *obj_type );

---

🎀 ARGUMENTS 🎀

• obj_type — the object type, periodt. that's the whole argument, she's not complicated 🫶

---

🦋 DESCRIPTION 🦋

So what she does is register the object type so it can be used with nf_tables 💅 no cap, that's it.

She returns zero on success, or a negative errno code otherwise — so if you get a negative back, that's your vibe check failing, not a slay 😭
