uclogic_params_pen_init_v1(9)

✨ NAME ✨

okay bestie, welcome to uclogic_params_pen_init_v1(9) — that’s the Kernel API Manual, section 9, and this page is all about uclogic_params_pen_init_v1: initialize tablet interface pen input and retrieve its parameters from the device, using v1 protocol. Periodt. 💅

🌸 SYNOPSIS 🌸

int uclogic_params_pen_init_v1 (struct uclogic_params_pen *pen , bool
*pfound , struct hid_device *hdev );

🎀 ARGUMENTS 🎀

• pen — pointer to the pen parameters to initialize (to be cleaned up with uclogic_params_pen_cleanup). Not modified in case of error, or if parameters are not found. Cannot be NULL. literally cannot be NULL, bestie 🫶
• pfound — location for a flag which is set to true if the parameters were found, and to false if not (e.g. device was incompatible). Not modified in case of error. Cannot be NULL. no cap, that NULL rule is real 😭
• hdev — the HID device of the tablet interface to initialize and get parameters from. Cannot be NULL. yes, also cannot be NULL 💀

🌈 RETURN 🌈

Zero, if successful. A negative errno code on error. that’s the whole vibe check 🔥
