💅 NAME 💅

batadv_netlink_notify_hardif — bestie, this one sends hardif attributes to the listener ✨

(also hi, you're reading the Kernel API Manual, welcome to the group chat 🫶)

---

🦋 SYNOPSIS 🦋

int batadv_netlink_notify_hardif (struct batadv_priv *bat_priv , struct
batadv_hard_iface *hard_iface );

okay so it takes exactly two things and returns an int, that's the whole vibe 💅

---

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv, aka the main character that's holding all the mesh interface information 👑
• hard_iface — the hard interface that got modified, the one that changed, the one we're here to talk about 🔥

---

⭐ RETURN ⭐

• 0 on success — slay, we ate 💖
• < 0 on error — not the vibe, something went wrong 😭

💀 reminder bestie: the page says < 0 on error and that's it, so just check your return value and don't go inventing extra behaviour, ok? 🙈

okay that's the whole page, ily, go read your kernel source 🌈

this gem dropped from ./net/batman-adv back in October 2026 — catch you in the next one, mwah 🧚💜
