💖 uncompress_data_vio(9) 💖

okay so bestie, welcome to the Kernel API Manual page for uncompress_data_vio(9) — yes that's the title AND the manual, we're folding it in right here at the top like a little name tag 🎀

---

✨ NAME ✨

uncompress_data_vio — literally the function that uncompresses the data a data_vio has just read. that's it, that's the whole vibe 🫶

---

🌸 SYNOPSIS 🌸

int uncompress_data_vio (struct data_vio *data_vio , enum
block_mapping_state mapping_state , char *buffer );

like… she returns an int, she takes three things, she's booked and busy 💅

---

🦋 ARGUMENTS 🦋

• data_vio — the data_vio. the main character of this whole operation, no cap 👑
• mapping_state — the mapping state that tells you which fragment to decompress ✨ like a little map that says "that one, bestie"
• buffer — the buffer that receives the uncompressed data. she's the receiving end of this whole glow-up 🍓
