__cdns3_gadget_ep_set_halt(9)

💅 __cdns3_gadget_ep_set_halt — like, the real title 💅

okay so this is a page from the Kernel API Manual, and bestie, it's a short one but it's important, so let's get into it ✨

🌸 NAME 🌸

__cdns3_gadget_ep_set_halt — sets stall on selected endpoint. Should be called after acquiring spin_lock and selecting ep. 🎀

no like fr fr, read that twice. the "should be called after acquiring spin_lock and selecting ep" part is not decorative, it's the whole vibe check. 👑

---

🦋 SYNOPSIS 🦋

void __cdns3_gadget_ep_set_halt (struct cdns3_endpoint *priv_ep );

it returns void, so like… it doesn't hand you anything back. it just does the thing and dips. main character energy honestly 💅

---

🌈 ARGUMENTS 🌈

• priv_ep — endpoint object to set stall on. that's it. that's the one (1) argument. hand it the endpoint object and it does its little stall-setting ritual on it 🫶
