💜 plpks_get_usedspace(9) — a Kernel API Manual moment ✨

okay bestie, settle in, because this one is short and sweet but it's literally the whole vibe of PLPKS housekeeping 🧚

---

🌸 NAME 🌸

plpks_get_usedspace — the girly that tells you how much space is used out of the total size of the PLPKS 💅

---

✨ SYNOPSIS ✨

u32 plpks_get_usedspace (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments. none. zero. she takes nothing, she gives you a number. icon behaviour 🫶

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this function invokes the H_PKS_GET_CONFIG HCALL to refresh the latest value for the used space. why refresh? because that number keeps changing as objects get created and removed in the PLPKS 😭 it's giving "my storage situation is a moving target" and honestly, relatable.

basically: call her, she pokes the hypervisor, you get the freshest used-space number available. no cap.

---

⭐ RETURN ⭐

• On success the used space is returned 🔥
• 0 if not 💀
