batadv_choose_backbone_gw(9)

💅 batadv_choose_backbone_gw(9) — or, the glow-up guide to picking a hash bucket 💅

okay so bestie, welcome to the Kernel API Manual ✨ this one's a little cutie from the batman-adv world and honestly it's giving "tiny function, big responsibilities." no cap. 🦋

---

🌸 NAME 🌸

batadv_choose_backbone_gw — choose the right bucket for a backbone gateway.

like, literally just picking which bucket a backbone gateway belongs in. that's the whole job. main character energy for a hash function, fr fr 💅

---

✨ SYNOPSIS ✨

u32 batadv_choose_backbone_gw (const void *data , u32 size );

yes that's it. that's the whole signature. short and iconic 🎀

---

🎯 ARGUMENTS 🎯

• data — the data to hash. this is the thing getting tossed into the bucket-finding machine 🫶
• size — size of the hash table. yep, it needs to know how many buckets exist so it doesn't invent a new one 😭

---

🔥 RETURN 🔥

the hash index of the backbone gateway. that's the answer, bestie — one little index, but it's the index 👑
