plpks_get_version(9)

💅 plpks_get_version — a Kernel API Manual moment (section 9, bestie)

okay so this is plpks_get_version(9) from the Kernel API Manual, and honestly? it's a little one-but-mighty icon. it does exactly one thing and it does it adorably. let's get into it ✨

---

🌸 NAME 🌸

plpks_get_version — get the version of the PLPKS config structure. that's it. that's the whole job. she's a specialist 🎀

---

🦋 SYNOPSIS 🦋

u8 plpks_get_version (void );

look at her. no drama, no parameters, just vibes and a u8 💜

---

✨ ARGUMENTS ✨

• void — no arguments. literally none. she takes nothing from you, she gives everything 🫶

---

💖 DESCRIPTION 💖

so here's the lore 👑 — during initialization, when the H_PKS_GET_CONFIG HCALL runs successfully, it reads the version of the PLPKS config structure. and then? it saves that version into a file local static version variable. lowkey a little treasure chest, tucked away for later 📦✨

no cap, that's the whole flow. hcall slays → version gets read → static variable holds onto it 💅

---

🔥 RETURN 🔥

• on success, you get back that saved PLPKS config structure version 💫
• and if not? you get 0. that's the "no thoughts, head empty" answer 😭
