💅 batadv_get_real_netdev(9) — kernel API manual, section 9, bestie

okay so this is a kernel API manual page for batadv_get_real_netdev, living in section 9 of the manual, and honestly? it's short but it's important, so let's go 🫶

---

✨ NAME ✨

batadv_get_real_netdev — the function that checks whether the net_device struct you handed it is a virtual interface sitting on top of another, "real" interface 🦋

like, is your netdev wearing a costume? this function finds out. no cap.

---

🌸 SYNOPSIS 🌸

struct net_device * batadv_get_real_netdev (struct net_device *net_device );

one argument in, one struct net_device * out. cute, clean, iconic 🔥

---

🎀 ARGUMENTS 🎀

• net_device — the device to check 💖 literally just hand it the device you're curious about and let it do its thing.

---

👑 RETURN 👑

it gives you back the 'real' net device, or the original net device — and NULL in case of an error 😭

so: real one, or the same one you gave it, or NULL if something went sideways. three possible vibes, one return value. periodt.

ngl, always check for that NULL before you go dereferencing anything, bestie 💀
