initialize_recovery_block(9)

💫 initialize_recovery_block(9) — like, the glow-up ritual for a journal block ✨

okay so first thing, bestie: this is a Kernel API Manual page, and the star of the show is initialize_recovery_block(9). She's the one who gets a journal block all dressed and ready for the function. 🎀

---

🌸 NAME

initialize_recovery_block — literally just Initialize a journal block. that's it, that's the whole vibe. 🦋

---

✨ SYNOPSIS

int initialize_recovery_block (struct vdo *vdo , struct recovery_journal
*journal , struct recovery_journal_block *block );

she takes three things and gives you back an int. iconic signature honestly. 💅

---

💖 ARGUMENTS

• vdo — the vdo you're pulling vios out of. it's giving "source of truth" energy, no cap. 🌈
• journal — the journal that this block is gonna belong to. she's gotta know her people. 🫶
• block — the actual block getting initialized. this is the main character of the whole operation. 👑

---

🔥 RETURN

VDO_SUCCESS or an error. that's it. either we slayed or we didn't, fr fr. 💀
