batadv_netlink_get_hardif(9)

💅 batadv_netlink_get_hardif(9) — from the Kernel API Manual, bestie ✨

okay so bestie, real talk: this function is literally the moment when you need to pull a hard interface out of a netlink callback. yes, that specific vibe. it retrieves hard interface from netlink callback, no cap, and it does it with main character energy 😌🫶

---

✨ SYNOPSIS ✨

struct batadv_hard_iface * batadv_netlink_get_hardif (struct batadv_priv
*bat_priv , struct netlink_callback *cb );

like, look at that signature. it's giving "I know exactly what I'm doing" 💅

---

🌸 ARGUMENTS 🌸

• bat_priv — the bat priv with all the mesh interface information. yes she contains multitudes, all the mesh deets are in there 🎀
• cb — callback structure containing arguments. that's where the callback args live, periodt 🦋

---

🔥 RETURN 🔥

• on success — pointer to hard interface, and bestie note the (with increased refcnt) part because refcounts are serious business 💖
• on error — error pointer. so if things go sideways you get an error pointer, not a cute moment 😭
