hid_hw_request(9)

✨ hid_hw_request 💅

okay bestie, welcome to the Kernel API Manual 🫶 — yes we're literally in the kernel docs and no, it's not scary, i promise. today's main character is hid_hw_request, and she does exactly one (1) thing but she does it iconically.

---

🌸 NAME 🌸

hid_hw_request — sends a report request to the device, no cap 🎀

---

💖 SYNOPSIS 💖

void hid_hw_request (struct hid_device *hdev , struct hid_report *report
, enum hid_class_request reqtype );

like, that's the whole signature. three args, void return, she's not giving you anything back — she just does it. periodt. 🔥

---

🦋 ARGUMENTS 🦋

• hdev — the hid device. your guy. the one you're talking to. 🫶
• report — the report you want to send. this is the actual thing going out the door. 💌
• reqtype — the hid request type. yes, like which kind of request. the vibe check of the whole call, honestly. ✨

ngl, all three are required — there's no "just vibes" overload here, bestie. you pass all three or you pass nothing. 💀
