💖 cmd_db_read_aux_data(9) — it's a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual entry for cmd_db_read_aux_data — yes that's a whole mouthful but stay with me, it's literally just "go ask the command db for some aux data and it hands you a pointer" 🫶 no cap.

---

✨ NAME ✨

cmd_db_read_aux_data — Query command db for aux data.

like, that's the whole job. you want aux data, you query the db, you get aux data. iconic behaviour honestly 🌸

---

🎀 SYNOPSIS 🎀

const void * cmd_db_read_aux_data (const char *id , size_t *len );

yep that's the whole signature, copy it exactly bestie, don't be out here renaming things 💅

---

🦋 ARGUMENTS 🦋

• id — the Resource you're retrieving AUX Data on. like, which thing are we asking about. main character resource energy ✨
• len — size of data buffer returned. it tells you how much data you got back, so you're not out here guessing 🌈

---

🔥 RETURN 🔥

pointer to data on success, error pointer otherwise.

so like... vibe check: if it worked you get a pointer to data, and if it didn't you get an error pointer. that's it, that's the deal 💀 please actually check which one you got, i'm begging 🙈
