rt2x00usb_re...er_multiread(9)

💅 rt2x00usb_register_multiread(9) 💅

okay bestie, so this is a page straight out of the Kernel API Manual — yes, the actual kernel docs, and yes, we're gonna make it cute. this is rt2x00usb_register_multiread(9) and she's a little function that just reads registers. iconic behavior honestly. 🎀

---

✨ NAME ✨

rt2x00usb_register_multiread — Read 32bit register words 🦋

like the name says, she reads 32bit register words. plural. multiple. multiread. the way that name foreshadows.

---

🌸 SYNOPSIS 🌸

void rt2x00usb_register_multiread (struct rt2x00_dev *rt2x00dev , const
unsigned int offset , void *value , const u32 length );

that's the whole signature fr — four params, returns void, no cap. 💜

---

🎀 ARGUMENTS 🎀

four of them, bestie, let's go through them one by one, no skipping:

• rt2x00dev — the Device pointer 💖 see struct rt2x00_dev. she needs to know which device she's talking to, obviously.
• offset — Register offset ✨ literally just where the register lives.
• value — Pointer to where register contents should be stored 🫶 this is the output spot, the little home where the data goes to live.
• length — Length of the data 🌈 how much stuff we're moving, in case you forgot.

---

🦋 DESCRIPTION 🦋

okay so what does she actually do?

she's a simple wrapper for 32bit register access through rt2x00usb_vendor_request_buff. that's it. that's the whole personality. a thin, elegant little wrapper doing her one job and doing it well. not me being obsessed with a wrapper function 😭

so like, when you call her, she's just handing the actual work off to rt2x00usb_vendor_request_buff — she's the main character of her own function but also lowkey a middleman. and honestly? respect. 💅

🫶 a little note from the source: this page lives at ./drivers/net/wireless/ralink/... and it's dated October 2026 — so yeah, future knowledge, we stay ahead of the timeline bestie ⭐ and the whole thing is filed under rt2x00usb_re...er_multiread(9) because even manpage headers get truncated sometimes, and that's valid 🙈

slay, you now know everything about reading 32bit register words 💖✨🎀
