nft_pipapo_init(9)

💖 NAME 💖

okay so we are in the Kernel API Manual, and today’s main character is nft_pipapo_init(9) — literally the function that initialises data for a set instance. bestie, it’s giving setup era. ✨

✨ SYNOPSIS ✨

the signature is right here, no cap:

int nft_pipapo_init (const struct nft_set *set , const struct
       nft_set_desc *desc , const struct nlattr * const nla[] );

🎀 ARGUMENTS 🎀

• set — the nftables API set representation. like, the set in question, hi bestie 👋
• desc — the set description. the little descriptor bestie 🎀
• nla — netlink attributes. the netlink attrs are pulling up 🦋

🦋 DESCRIPTION 🦋

okay so nft_pipapo_init() validates the number and size of fields passed as NFTA_SET_DESC_CONCAT netlink attributes. then it initialises the internal set parameters, the current instance of matching data, and a copy for subsequent insertions. periodt. 💅

🌸 RETURN 🌸

0 on success, and a negative error code on failure. simple as that, bestie. no cap. 😭
