set_active_sector(9)

🎀 set_active_sector(9) 🎀

okay so bestie, this one is from the Kernel API Manual, and it’s giving “one tiny kernel helper, one very specific job.” The job? Set the current sector of the current block and initialize it. That’s it. Slay. 💅

✨ NAME ✨

set_active_sector — set the current sector of the current block and initialize it. no cap, that’s the whole vibe. 🫶

🔥 SYNOPSIS 🔥

void set_active_sector (struct recovery_journal_block *block , void *sector );

🌸 ARGUMENTS 🌸

• block — the block to update. literally the block that’s getting its moment. 👑
• sector — a pointer to the first byte of the new sector. yes, the very first byte, bestie. ✨
