reset_ppn_array(9)

💅 reset_ppn_array(9) 💅

ok so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding era 🫶 and today's main character is reset_ppn_array. it's a little function, it does one thing, and it does it flawlessly. no cap.

---

✨ NAME ✨

reset_ppn_array — resets a PPN64 array to INVALID_PPN64 content 🌸

like, it takes your array and makes it invalid. on purpose. that's the whole job. iconic behaviour honestly.

---

🦋 SYNOPSIS 🦋

void reset_ppn_array (PPN64 *arr , size_t size );

that's it. that's the whole signature. void return, so it gives you nothing back except vibes and a freshly reset array 💀

---

🎀 ARGUMENTS 🎀

• arr — the array you want to reset 💖 like, hand it over, it's getting reset.
• size — how long that array is 📏 (the array length, bestie, not the byte count, don't come for me).
