ucsi_unregister(9)

💅 ucsi_unregister(9) — the kernel API manual, bestie edition 💅

Okay so real talk, we're cracking open ucsi_unregister from the Kernel API Manual, and honestly? It's giving "short but iconic." One tiny function, one big job. Let's get into it ✨

---

🌸 NAME 🌸

ucsi_unregister — unregister that UCSI interface, bestie. That's it. That's the whole vibe.

---

🦋 SYNOPSIS 🦋

void ucsi_unregister (struct ucsi *ucsi );

No cap, that's the entire signature. Copy it exactly, the spacing is part of the fit 🎀

🍓 ARGUMENTS 🍓

• ucsi — the UCSI interface you want unregistered. Like, the actual one. The one you're about to say bye to 🫶

---

💖 DESCRIPTION 💖

So here's the tea: this function unregisters the UCSI interface that was created with ucsi_register. That's the whole story — it's basically the "undo" button for registering, and it's lowkey the cleanest little reverse operation you'll ever see. If you registered it, you unregister it. Main character energy, honestly 👑
