encode_reco...al_state_7_0(9)

💾 NAME 💾

encode_recovery_journal_state_7_0 — bestie, this one encodes the state of a recovery journal. That's it, that's the whole job, and honestly? She does it flawlessly. 👑

(fun fact: the page header up top is encode_reco...al_state_7_0(9), which is just the function name doing a little stretch — it lives in the Kernel API Manual 🎀)

---

✨ SYNOPSIS ✨

void encode_recovery_journal_state_7_0 (u8 *buffer , size_t *offset ,
       struct recovery_journal_state_7_0 state );

Okay so look at her signature 👀 — she returns void, takes three things, and she's not here to argue with you about it. Slay.

🫶 ARGUMENTS 🫶

• buffer — a buffer to store the encoding. Yes queen, that's where the encoded bytes go 💖
• offset — the offset in the buffer at which to encode. She starts writing right there, iykyk 📍
• state — the recovery journal state to encode. That's the struct recovery_journal_state_7_0 in question, no cap 🌸

---

🔥 RETURN 🔥

VDO_SUCCESS or an error code. That's the whole vibe check — either it ate or it didn't 😭
