batadv_tt_hash_find(9)

💅 batadv_tt_hash_find(9) — Kernel API Manual ✨

okay so bestie, welcome to the kernel docs, Gen Z edition. this one lives in the Kernel API Manual, and it's a tiny little lookup function that's honestly doing the most for the translation table 🎀

---

🌸 NAME 🌸

batadv_tt_hash_find — look for a client in the given hash table. that's it, that's the whole vibe. it's giving "front desk checking if you're on the list" 💅

---

✨ SYNOPSIS ✨

struct batadv_tt_common_entry * batadv_tt_hash_find (struct
batadv_hashtable *hash , const u8 *addr , unsigned short vid );

like, hand it a hash table, a MAC address, and a VLAN id, and it goes digging 🔍

---

🦋 ARGUMENTS 🦋

• hash — the hash table to search. this is the place you're rummaging through, no cap.
• addr — the mac address of the client to look for. yes, that client. the one you're thinking about. 👀
• vid — VLAN identifier. gotta know which VLAN lane your fave is in 💜

---

👑 RETURN 👑

a pointer to the tt_common struct belonging to the searched client if found, and NULL otherwise. so either you get your entry back (slay) or you get NULL (😭 it's giving "not on the list"). always check, bestie, always check.
