💅 aa_unpack_u16_chunk(9) — Kernel API Manual, bestie edition 🎀

🌸 NAME 🌸

aa_unpack_u16_chunk — she tests and does bounds checking for a u16 size based chunk. that's the whole job. that's the assignment. periodt 💅

---

🦋 SYNOPSIS 🦋

VISIBLE_IF_KUNIT size_t aa_unpack_u16_chunk (struct aa_ext *e , char
**chunk );

not me copying this exactly because you cannot be out here paraphrasing a function signature, bestie. VISIBLE_IF_KUNIT, size_t, the whole vibe — verbatim, no notes 🔥

---

✨ ARGUMENTS ✨

• e — the serialized data read head. and listen: it is NOT NULL. do not come in here with a null e, that's not the energy we're bringing today 😭
• chunk — the start address for the chunk of data. also NOT NULL. both of these are mandatory, no cap 🙈

---

👑 RETURN 👑

she returns the size of the chunk, and the read head ends up sitting at the end of the chunk. so you get the size and you get moved along. multitasking main character energy fr fr 💖

🫶 reminder: e and chunk are NOT NULL. i will not be elaborating. (okay i will — it literally says NOT NULL. twice. that's a vibe check you should pass.)
