💅 batadv_compare_dat(9) — the Kernel API Manual moment

okay so bestie, buckle up, because we're talking about batadv_compare_dat, which lives in the Kernel API Manual and is literally the comparing function used in the local DAT hash table. that's it, that's the vibe. she's a little comparison queen and she's iconic for it 🎀

✨ NAME ✨

batadv_compare_dat — the comparing function used in the local DAT hash table. no cap, that's her whole job and she does it flawlessly 💅

---

🦋 SYNOPSIS 🦋

bool batadv_compare_dat (const struct hlist_node *node , const void
       *data2 );

---

🌸 ARGUMENTS 🌸

• node — a node in the local table. that's the first one up for the vibe check 👀
• data2 — the second object we're comparing the node to. yes bestie, two entries, one showdown 🫶

---

⭐ RETURN ⭐

• true if the two entries are the same 💖
• false otherwise 🙈

fr fr, that's the whole contract. true = twins, false = not twins. don't overthink it ✨
