batadv_tt_l...t_is_roaming(9)

📦 version 7.3.1, in nixpkgs unstable

💅 batadv_tt_local_client_is_roaming(9) — the "is my bestie ghosting this node??" check

okay so first things first: this is a Kernel API Manual page, section 9, and the function we're obsessing over is batadv_tt_local_client_is_roaming. yes the header got cutely truncated to batadv_tt_l...t_is_roaming(9) up top, but we're saying the whole name, periodt. 🎀

✨ NAME ✨

batadv_tt_local_client_is_roaming — literally tells you whether a client is roaming. that's it, that's the whole vibe check. 🦋

🌸 SYNOPSIS 🌸

bool batadv_tt_local_client_is_roaming (struct batadv_priv *bat_priv ,
u8 *addr , unsigned short vid );

look at her. returns a bool, takes three things. iconic signature, no notes. 💅

💖 ARGUMENTS 💖

  • bat_priv — the bat priv with all the mesh interface information. she's carrying the whole mesh's lore, bestie, respect her.
  • addr — the mac address of the local client you're querying. like, which client are we gossiping about?
  • vid — VLAN identifier. your girl lives in a specific VLAN and we gotta say which one. 🏷️

👑 RETURN 👑

returns true if the local client is known to be roaming — meaning it is not served by this node anymore — or not. 😭

and if it is yes? the client is still present in the table, and that's on purpose: it keeps the table consistent with the node TTVN. don't come for her for leaving the entry there, she has reasons. ✨

ngl the whole point is consistency. the entry stays so the table matches the node TTVN, so don't @ her about it. 🫶
