✨ NAME ✨

netlink_policy_dump_write — write current policy dump attributes 💖

like, it writes the attributes of the policy dump you're currently doing. that's the whole vibe. no cap.

🌸 SYNOPSIS 🌸

int netlink_policy_dump_write (struct sk_buff *skb , struct
       netlink_policy_dump_state *state );

that's the exact signature, character for character, don't come for me 😭 it returns an int, takes a struct sk_buff * and a struct netlink_policy_dump_state *, and yes the line break in the middle is from the original, we're keeping it, periodt ✨

🎀 ARGUMENTS 🎀

• skb — the message skb to write to 🦋 this is the buffer that's catching your output, she's the main character here
• state — the policy dump state 💅 the whole dump situation lives in here, this is what you're writing out

two args, both iconic, both required, no defaults, no surprises 🍓

---

⭐ RETURN ⭐

0 on success, an error code otherwise 🙈

so like, zero is the slay number. anything else means something went sideways and you should go check. fr fr.
