💖 amd_halo_wmi_get_rgb(9) 💖

okay so this is a page straight outta the Kernel API Manual (section 9, kernel-space girlies only ✨), and it's your girl explaining amd_halo_wmi_get_rgb — the little function that goes and gets you some RGB values. no cap, that's the whole plot 🎀

✨ NAME ✨

amd_halo_wmi_get_rgb — Get RGB values 💅

that's it. that's the name. it gets the RGB values. iconic behaviour honestly.

---

🦋 SYNOPSIS 🦋

int amd_halo_wmi_get_rgb (struct wmi_device *wdev , u8 *r , u8 *g , u8 *b );

look at her. four arguments, returns an int, zero notes. main character energy fr fr 🌸

🎀 ARGUMENTS 🎀

• wdev — WMI device pointer 🫶 lowkey the whole connection to the WMI device, so like, don't lose her.
• r — output buffer for red value 🔥 she outputs, she doesn't take input, remember that.
• g — output buffer for green value 💚 same deal, output buffer, green flavoured.
• b — output buffer for blue value 💙 and the blue one. trio complete, vibe check passed.

bestie these are output buffers, ok? the function writes into them. don't hand her garbage and expect a glow-up 🙈

• 0 on success — slay, we got the RGB 💖
• negative error code on failure — not slay, but at least she's honest about it 😭
