ib_ucaps_init(9)

💅 ib_ucaps_init — a Kernel API Manual moment ✨

okay so bestie, welcome to the ib_ucaps_init page 💖 this one lives in the Kernel API Manual, and it's lowkey the little pre-party ritual you gotta do before anything else happens. no cap.

---

🌸 NAME 🌸

ib_ucaps_init — the initialization you literally have to do before ucap creation 🎀

like, think of it as setting up the snack table before the guests arrive. the guests are ucaps. the snack table is this function. iykyk.

---

✨ SYNOPSIS ✨

int ib_ucaps_init (void );

that's the whole vibe. it returns an int, it takes nothing, it's giving minimal main character energy 👑

---

🦋 ARGUMENTS 🦋

• void — no arguments 🫶 nothing to pass in, nothing to worry about, she takes zero parameters and she's at peace with that

---

🔥 RETURN 🔥

• 0 — slay, it worked, success 💖
• a negative errno value — not slay 😭 something went wrong, and you get a negative errno back to tell you all about it

fr fr, check that return value. don't just call it and walk away like it's not gonna matter later 🙈

🌈 SEE ALSO 🌈
