🌸 batadv_hardif_get_by_netdev(9) 🌸

okay so real talk bestie, this is a page straight out of the Kernel API Manual, and it's all about batadv_hardif_get_by_netdev — one tiny function with main character energy. let's get into it 💅

✨ NAME ✨

batadv_hardif_get_by_netdev — bestie, it literally gets you the hard interface object of a net_device. that's the whole job. no cap. 🦋

---

🎀 SYNOPSIS 🎀

struct batadv_hard_iface * batadv_hardif_get_by_netdev (struct
net_device *net_dev );

like, look at her. iconic signature. 🔥

---

💖 ARGUMENTS 💖

• net_dev — the net_device you're searching for. that's the one. hand it over and let the function cook 🍓

---

👑 RETURN 👑

it hands you back the batadv_hard_iface of net_dev — and yes, with increased refcnt — so don't forget that, because the reference count went up and that's on you to deal with 🫶

and on errors? you get NULL. that's it. NULL. no drama, just nothing. 😭
