batadv_netlink_get_meshif(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, we're in the batadv_netlink_get_meshif(9) page today and honestly? it's a little icon. short, sweet, does exactly one thing. let's get into it 🫶

✨ NAME ✨

batadv_netlink_get_meshif — Retrieve mesh interface from netlink callback 🦋

like, that's the whole gig. it retrieves the mesh interface. from a netlink callback. she's focused, she's employed, she's not doing extra 💅

🌸 SYNOPSIS 🌸

struct net_device * batadv_netlink_get_meshif (struct netlink_callback *cb );

one function, one argument, one return type. minimalism ate fr fr ✨

🎀 ARGUMENTS 🎀

  • cb — the callback structure containing arguments. that's it, that's her whole job. she holds the args, you hand her over, everybody moves on 🌈

💖 RETURN 💖

so here's the vibe check on what comes back:

  • on success — a pointer to the mesh interface, and bestie, important detail: the refcnt is increased. like she comes with a hold on her, you gotta release that later, no cap 😭
  • on error — an error pointer. classic. not NULL, an error pointer, so please check it with the proper helpers, iykyk 💀
fr fr do not forget about that increased refcnt, that's the main character detail of this whole page 👑

👑 SEE ALSO 👑

the whole netlink friend group showed up for this one, and we are obsessed:

and if you wanna see where the source lives, it's chilling in the kernel file ./net/batman-adv/netlink.c alongside enum. go say hi 🧚

okay that's the page!! huge thank you to ./net/batman-adv for the source and to October 2026 for the date stamp, you both slayed this drop 🍓💜 stay hydrated, check your error pointers, and remember: increased refcnt means increased responsibility. periodt ✨🎀
