usb_unanchor_urb(9)

💅 usb_unanchor_urb(9) — from the Kernel API Manual, bestie ✨

okay so welcome to the glow-up edition of the usb_unanchor_urb page, straight out of the Kernel API Manual, and no cap this one's a shortie but a goodie 🎀

---

🌸 NAME 🌸

usb_unanchor_urb — unanchors an URB 🦋

like... that's the whole vibe. it unanchors it. bye anchor 👋

---

✨ SYNOPSIS ✨

void usb_unanchor_urb (struct urb *urb );

that's it, that's the function signature, and yes she returns void because she's not here to give you feedback, she's here to detach 💅

---

🎀 ARGUMENTS 🎀

• urb — pointer to the urb to anchor, i.e. the little guy you're handing over so he can get un-anchored 🫶

(that's the one and only argument, main character energy, no supporting cast 💖)

---

🔥 DESCRIPTION 🔥

call this to stop the system keeping track of this URB ✨

literally the whole thing. you call it, the system stops tracking the URB, and everyone moves on with their lives 😌 no drama, no return value, just closure 🦋

ngl it's giving "unfollow and soft block" — the tracking is just gone and you don't get a notification 💀
