cipso_v4_init(9)

💖 cipso_v4_init(9) 💖

okay bestie, welcome to the Kernel API Manual, section 9 — this is the little init function for the CIPSO module and honestly it's giving first day of school energy. 🎀

---

✨ NAME ✨

cipso_v4_init — literally just initializes the CIPSO module, that's the whole vibe 😌

---

🌸 SYNOPSIS 🌸

int cipso_v4_init (void );

---

🦋 ARGUMENTS 🦋

• void — no arguments, bestie. none. zero. nothing. it takes nothing, and honestly? iconic of it. 💅

---

🧚 DESCRIPTION 🧚

So what does it do? It initializes the CIPSO module and gets it all prepped and ready for use — like doing your skincare routine before bed so future-you doesn't suffer. 🫶

And the return situation, since I know you're gonna ask:

• returns zero on success — slay, we love a zero 💖
• returns negative values on failure — 😭 not the negative values, but okay, that's how you know something went sideways

ngl, always check the return value, bestie. zero = we're so back, negative = it's so over. 🔥
