💅 batadv_tp_li...iver_session(9) 💅

okay so real talk, bestie — this is the batadv_tp_li...iver_session(9) page out of the Kernel API Manual, and yes the title is literally truncated with the little ... in the middle, that's not a typo, that's just how it's printed, we love a mysterious queen 🎀

---

✨ NAME ✨

batadv_tp_list_find_receiver_session — find tp_vars receiver session object in the global list. that's it. that's the whole job. she finds, she returns, she slays 💅

---

🌸 SYNOPSIS 🌸

struct batadv_tp_receiver * batadv_tp_list_find_receiver_session (struct
batadv_priv *bat_priv , const u8 *dst , const u8 *session );

look at her. three args, one pointer out, zero drama (the good kind of zero drama, ngl) ✨

---

🦋 ARGUMENTS 🦋

• bat_priv — the bat priv with all the mesh interface information. she carries the whole squad's mesh-interface lore, okurrr 👑
• dst — the other endpoint MAC address to look for. like, who are we trying to find, address-wise 🫶
• session — session identifier. your little name tag for the tp meter session so we know which one's which 🎀

---

💜 DESCRIPTION 💜

so here's the vibe: she goes looking for a tp_vars object that matches dst as end_point, and session as tp meter session — both have to line up, no half-matching bestie, we don't do that here 💀

and when she finds it? she hands it back to you after having increment the refcounter. yes queen, she bumps that refcount before she lets go, that's the whole point 🔥

and if it's not found? NULL. that's it. don't overthink it 😭

careful, babes — the refcounter thing is load-bearing. she's not just returning a pointer, she's returning a pointer that's been counted. that's the contract 💅

---

⭐ RETURN ⭐

matching tp_vars, or NULL when no tp_vars was found. either she ate and found your receiver session, or she comes back empty-handed with NULL — no in-between, no maybes, periodt 🌈
