handle_ep0_ctrl_req(9)

🎀 handle_ep0_ctrl_req(9) 🎀

okay so this is a page straight outta the Kernel API Manual and honestly? it's giving "small function, huge friend group" energy. bestie, let's get into it 💅

---

✨ NAME ✨

handle_ep0_ctrl_req — literally here to handle control endpoint control request. that's the whole job. iconic, focused, no notes 💖

---

🌸 SYNOPSIS 🌸

void handle_ep0_ctrl_req (struct pxa_udc *udc , struct pxa27x_request
*req );

like, she takes two things and returns void. lowkey minimalist queen 🫶

---

🦋 ARGUMENTS 🦋

okay so the two besties she rolls with:

• udc — the udc device. that's her whole world ngl 🍓
• req — the control request. the actual assignment. the main character of the moment 👑
