set_ep0state(9)

okay so we're in the Kernel API Manual bestie, and today's main character is set_ep0state — she's small, she's specific, she sets a state, and honestly? iconic behavior ✨ let's get into it 🫶

set_ep0state — Set ep0 automata state 💅

like, the whole job. setting the ep0 automata state. no notes. periodt.

---

🦋 SYNOPSIS 🦋

void set_ep0state (struct pxa_udc *udc , int state );

that's literally the whole signature, no cap 🌸

• state — the state. that's the arg. that's what it is. the state 💫

and that's the whole page, bestie 🧚 this came out of the ./drivers/usb/gadget/udc corner of the kernel, dated October 2026, and the page itself is set_ep0state(9) 💜 go forth and set those states, you absolute legend 👑
