batadv_meshif_validate(9)

🦋 batadv_meshif_validate(9) — the vibe check for your brand-new batadv link

okay so real talk, bestie: this is a page from the Kernel API Manual, and it's all about one little function that looks at a fresh batman-adv link and goes "hmm, is this config actually valid or are we about to be a clown 🤡". Think of it as the bouncer at the club door of your mesh interface. No cap.

✨ NAME ✨

batadv_meshif_validate — literally validates the configuration of a new batadv link. that's it, that's the whole gig 💅

---

🌸 SYNOPSIS 🌸

int batadv_meshif_validate (struct nlattr *tb[] , struct nlattr *data[]
, struct netlink_ext_ack *extack );

she takes three things and hands you back an int. iconic signature, no notes 🫶

---

🎀 ARGUMENTS 🎀

• tb — the IFLA_INFO_DATA netlink attributes. yes, the whole array, she's nosy like that 👀
• data — the enum batadv_ifla_attrs attributes. the actual menu of options being checked 🍓
• extack — the extended ACK report struct. this is where the receipts get filed if something's sus 📝

---

⭐ RETURN ⭐

0 if successful, or an error otherwise. that's the whole deal — zero means slay, anything else means something went sideways 😭
