batadv_netl...if_from_info(9)

📦 version 7.3.1, in nixpkgs unstable

💅 batadv_netlink_get_meshif_from_info — like, the whole page

okay so bestie, we're in the Kernel API Manual today and honestly? This one's a little baddie. It's the batadv_netlink_get_meshif_from_info page and it does exactly one thing but it does it iconically.

🎀 NAME 🎀

batadv_netlink_get_meshif_from_info — Get mesh-iface from genl attributes ✨

(yeah that's it. that's the whole job. and she ate.)

🌸 SYNOPSIS 🌸

struct net_device * batadv_netlink_get_meshif_from_info (struct net *net
, struct genl_info *info );

literally just: you hand her a net and an info, she hands you back a struct net_device *. no drama. 💅

🦋 ARGUMENTS 🦋

  • net — the applicable net namespace 🫶 (like, which world are we living in rn)
  • info — receiver information 📬 (the genl attributes, the lore, the context)

👑 RETURN 👑

Pointer to mesh interface (with increased refcnt) on success, error pointer on error.

⚠️ okay important bestie: on success you get a refcnt bump, so like… that reference is yours to hold. don't just leave it lying around, that's not the vibe. and on error you get an error pointer — check it with IS_ERR()-style thinking, don't dereference it, that would be so embarrassing for everyone involved 😭

🔥 SEE ALSO 🔥

Kernel file ./net/batman-adv/netlink.c plus enum batadv_netlink_multicast_groups(9), enum batadv_genl_ops_flags(9) — and honestly the whole friend group, we're listing them all because everyone deserves their moment:
