📦 version 7.3.1, in nixpkgs unstable

💅 batadv_mcast_forw_orig_entry

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our life now, and honestly? iconic. grab a matcha 🍓

✨ NAME ✨

batadv_mcast_forw_orig_entry — get the orig_node out of an hlist node 🎀

🌸 SYNOPSIS 🌸

struct batadv_orig_node * batadv_mcast_forw_orig_entry (struct
       hlist_node *node , size_t entry_offset );

like, you hand it a node and an offset and it hands you back the orig_node, no cap 💖

🦋 ARGUMENTS 🦋

  • node — the hlist node you want the orig_node from, bestie. that's the whole assignment.
  • entry_offset — the offset of that hlist node within the orig_node struct. yes it's a size_t, yes you need it, no you cannot skip it 🙈

👑 RETURN 👑

The orig_node containing the hlist node on success — slay ✨ — and NULL on error 😭 (which is the vibe check failing, fr).

ngl, always check for that NULL. it's giving "i forgot to check and now everything is on fire" energy 💀
