batadv_get_vlan_from_info(9)

💅 batadv_get_vlan_from_info — Kernel API Manual ✨

Okay so bestie, welcome to the manual page for batadv_get_vlan_from_info(9), straight out of the Kernel API Manual. Yes it's a mouthful, no you don't have to say it out loud, but it IS the function we're about to obsess over. 🫶

---

🌸 NAME 🌸

batadv_get_vlan_from_info — retrieve vlan from genl attributes. That's it, that's the whole vibe. 💫

---

🦋 SYNOPSIS 🦋

struct batadv_meshif_vlan * batadv_get_vlan_from_info (struct
batadv_priv *bat_priv , struct net *net , struct genl_info *info );

Like, look at that signature. It's giving "I take three pointers and I give you back a vlan." Main character energy fr fr. 👑

---

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv with all the mesh interface information. This is the big one, the info hub, the girl who knows everybody. 💖
• net — the applicable net namespace. Which little universe of networking are we in, bestie? 🌈
• info — receiver information. The genl info that comes flying in. 📨

---

⭐ RETURN ⭐

Pointer to vlan on success — and yes, it comes back with an increased refcnt, so mind your references, no cap. On error you get an error pointer back. 😭

Heads up bestie: error pointer means you check it with the error-checking macros, you don't just deref it. That refcnt ain't gonna decrement itself. 💀
