batadv_iv_og...h_ifinfo_sum(9)

okay so bestie, this is a page from the Kernel API Manual for batadv_iv_ogm_neigh_ifinfo_sum — the header label got absolutely squished into batadv_iv_og...h_ifinfo_sum(9), but we're still gonna understand it together. 💅✨

💖 NAME 💖

batadv_iv_ogm_neigh_ifinfo_sum — Get bcast_own sum for a last-hop neighbor. That's the whole name-vibe, and yes it's giving very specific kernel lore. 🫶

✨ SYNOPSIS ✨

here's the signature, untouched, because we do not edit code in this house:

u8 batadv_iv_ogm_neigh_ifinfo_sum (struct batadv_priv *bat_priv , const
struct batadv_neigh_node *neigh_node );

🦋 ARGUMENTS 🦋

• bat_priv — the bat priv with all the mesh interface information. It's literally holding the mesh-interface receipts. 🫶
• neigh_node — last-hop neighbor of an originator. Your last-hop bestie, no cap. 💅

🌸 RETURN 🌸

It hands back a u8: the Number of replied (rebroadcasted) OGMs for the originator currently announced by the neighbor. And if the neighbor's originator entry is not available anymore, it returns 0 — that's the fallback, periodt. 😭🫶
