💅 uclogic_par..._event_hooks(9) — a Kernel API Manual moment

okay so bestie, pull up a chair, because this is the function that initializes the list of events to be hooked for UGEE v2 devices and honestly it's giving "small but crucial" 💖 (also hi, yes, this is from the Kernel API Manual, we're doing kernel lore today 🎀)

It's a 9th-section page, so it's ~driver internals~ territory — that's the kernel developers only section, iykyk 🧚

✨ NAME ✨

uclogic_params_ugee_v2_init_event_hooks — initializes the list of events to be hooked for UGEE v2 devices 🔥

Like, it's the setup girlie that decides which events get hooked. No cap.

---

🌸 SYNOPSIS 🌸

int uclogic_params_ugee_v2_init_event_hooks(struct hid_device *hdev,
                                            struct uclogic_params *p);

Returns an int, takes a struct hid_device *hdev and a struct uclogic_params *p, and then a space before each comma because kernel style said so 🫶 (the original writes it struct hid_device *hdev , struct uclogic_params *p — blessed be the formatting, we don't touch it)

---

🦋 ARGUMENTS 🦋

• hdev — the HID device of the tablet interface to initialize and get parameters from 🖊️ like, this is the tablet interface bestie, we're pulling params out of it.
• p — parameters to fill in. cannot be NULL. ⚠️ not me warning you twice — seriously, do not pass NULL here, that's a one-way ticket to sad times 💀

---

⭐ RETURN ⭐

• Zero — if successful ✨ slay, we love a zero.
• A negative errno code — on error 😭 that's the "something went sideways" vibe check fail.

That's the whole return contract, no secret extras. periodt.

lowkey reminder: p cannot be NULL. this is a load-bearing fact, bestie, don't come for me when it explodes 🙈
