dwc3_event_buffers_setup(9)

🌸 NAME 🌸

dwc3_event_buffers_setup — the lil glow-up moment where we set up all the event buffers we already allocated 💅

---

🦋 SYNOPSIS 🦋

int dwc3_event_buffers_setup (struct dwc3 *dwc );

---

🎀 ARGUMENTS 🎀

• dwc — pointer to our controller context structure, aka the main character struct we're doing all this for 🫶

---

✨ DESCRIPTION ✨

Okay so this function does the setup work on the event buffers we already allocated earlier, and it reports back how it went: it returns 0 on success, otherwise a negative errno. That's it, that's the whole vibe check 🧚

No cap, that's literally the entire contract — no extra lore, no hidden side quests in the docs.
