batadv_dat_init(9)

💖 batadv_dat_init(9) 💖

okay so bestie, welcome to the batadv_dat_init page from the Kernel API Manual — yes that Kernel API Manual, the one with all the lore. this one's short and sweet but it's literally the origin story for the DAT internals, so pay attention 🎀

---

✨ NAME ✨

batadv_dat_init — initialise the DAT internals. that's it. that's the whole vibe check. it sets the DAT stuff up so the rest of the mesh can actually do its thing 🦋

---

🌸 SYNOPSIS 🌸

int batadv_dat_init (struct batadv_priv *bat_priv );

one function, one argument, one int coming back at you. iconic honestly 💅

---

🧚 ARGUMENTS 🧚

• bat_priv — the bat priv with all the mesh interface information. yeah, all of it. this is the main character struct keeping track of everything about your mesh interface, so hand it over and let DAT do its thing 🫶

---

⭐ RETURN ⭐

• 0 — success, we slayed, everything's initialised 💖
• a negative error code — otherwise 😭 something went sideways, and the negative number is the receipts
