✨ plpks_wrapping_is_supported ✨

okay so bestie, welcome to the plpks_wrapping_is_supported(9) page from the Kernel API Manual 💖 this one's short and sweet and honestly kind of iconic for it.

---

🌸 NAME 🌸

plpks_wrapping_is_supported — the lil function that tells you whether the H_PKS_WRAP_OBJECT interface is available on this LPAR or not 🫶

---

🎀 SYNOPSIS 🎀

bool plpks_wrapping_is_supported (void );

---

🦋 ARGUMENTS 🦋

• void — literally no arguments. nothing. zero. it takes nothing, it needs nothing, main character energy 💅

---

💜 DESCRIPTION 💜

so here's the tea ☕ during initialization, if the H_PKS_GET_CONFIG HCALL runs successfully, it sets bit 3 of the flags variable inside the PLPKS config structure — but only if the H_PKS_WRAP_OBJECT interface is supported. that's the whole bit. that's the vibe check. 🌈

---

⭐ RETURN ⭐

• true — if the H_PKS_WRAP_OBJECT interface is supported 🔥
• false — if it's not 🙈
