libie_ctlq_xn_init(9)

💅 libie_ctlq_xn_init(9) — kernel API manual, but make it make sense 🎀

okay so bestie, we're in the Kernel API Manual today and the star of the show is libie_ctlq_xn_init — the girl whose whole job is setting up the Xn transaction manager. she's giving "first day of school, gotta get everything in place" energy and honestly? iconic. ✨

---

🌸 NAME 🌸

libie_ctlq_xn_init — literally just initialize the Xn transaction manager. that's it. that's the whole vibe. 💖

---

🦋 SYNOPSIS 🦋

int libie_ctlq_xn_init (struct libie_ctlq_xn_init_params *params );

one function, one pointer, one int coming back at you. clean. minimal. slay. 💅

---

👑 ARGUMENTS 👑

• params — the Xn init param info 🫶 this is the little bundle of details she needs to go allocate all the Xn manager resources. think of it as her packing list before the trip. no params, no party. 🙈

---

⭐ RETURN ⭐

• 0 on success — we love a zero, we stan a zero, zero is the moment. 🎉
• -errno on failure — boo, but at least she tells you why with a negative errno. no mystery, no games. 💀
