batadv_find_best_neighbor(9)

✨ batadv_find_best_neighbor ✨

okay so bestie, pull up a chair 🎀 this one lives in the Kernel API Manual and it's called batadv_find_best_neighbor — and yes the name lowkey spoils the whole plot: it finds the best neighbor after purging. icon behavior, honestly 💅

🌸 SYNOPSIS 🌸

struct batadv_neigh_node * batadv_find_best_neighbor (struct batadv_priv
*bat_priv , struct batadv_orig_node *orig_node , struct
batadv_hard_iface *if_outgoing );

she returns a struct batadv_neigh_node *, no cap 🦋

💖 ARGUMENTS 💖

• bat_priv — the bat priv with all the mesh interface information. it's giving "the main character who holds everyone's info" 👑
• orig_node — orig node which is to be checked. like, the one we're side-eyeing 🙈
• if_outgoing — the interface for which the metric should be compared. this is the vibe check interface, fr fr ✨

⭐ RETURN ⭐

the current best neighbor, with refcount increased. not me reminding you that the refcount goes UP — pls don't leak it, bestie 😭🫶
