xudc_ep_enable(9)

✨ xudc_ep_enable(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's called xudc_ep_enable — and yeah, it does exactly what it says on the tin: it enables the given endpoint 🔥

---

🎀 SYNOPSIS 🎀

int xudc_ep_enable (struct usb_ep *_ep , const struct
usb_endpoint_descriptor *desc );

short king of a signature, honestly. returns an int, takes two pointers, no cap 🫶

---

🌸 ARGUMENTS 🌸

• _ep — a pointer to the usb endpoint structure. like, the endpoint in question, the main character of this whole situation 👑
• desc — a pointer to the usb endpoint descriptor. it's the little info card that tells everyone what this endpoint actually is 🎀

---

💖 RETURN 💖

• 0 on success — slay ✨
• an error value on failure — not slay 😭

that's literally it. 0 good, error bad, the whole vibe check in one line fr fr.
