unpack_profile(9)

💅 unpack_profile(9) — or, the kernel API manual's main character

Okay bestie, welcome to unpack_profile from the Kernel API Manual — yes that's the manual section, we're in the big leagues now (section 9, kernel API, no cap) ✨

---

🎀 NAME

unpack_profile — unpack a serialized profile. That's the whole vibe. It takes serialized stuff and unpacks it. Slay.

---

✨ SYNOPSIS

struct aa_profile * unpack_profile (struct aa_ext *e , char **ns_name );

Look at that signature, she's giving function-call realness 🫶

---

🧚 ARGUMENTS

• e — serialized data extent information (NOT NULL, okay?? like, do NOT pass NULL, that is not the move 🙈).
• ns_name — pointer of newly allocated copy of NULL in case of error. That's what the docs say, word for word, and I'm not gonna gaslight you about it 💀

---

💀 NOTE

Lowkey important: unpack profile sets audit struct if there is a failure. So if things go sideways, the audit struct gets set. Noted, remembered, filed under "iykyk" 📝

🍓 Quick vibe check recap: e is NOT NULL, ns_name is that pointer-of-newly-allocated-copy-of-NULL-in-case-of-error situation, and failures set the audit struct. Periodt.
