b43_radio_write(9)

💖 b43_radio_write(9) — the Kernel API Manual page, bestie edition 💖

okay so we're in the Kernel API Manual today and the main character of this page is b43_radio_write, a tiny little 16bit radio register write function that honestly does exactly what it says on the tin. no notes. iconic behavior. ✨

🌸 NAME 🌸

b43_radio_write — 16bit Radio register write access

like, it writes a 16-bit value into a radio register. that's the whole vibe. 🎀

---

🦋 SYNOPSIS 🦋

void b43_radio_write (struct b43_wldev *dev , u16 reg , u16 value );

look at her go. void return, so she doesn't give anything back — she just does it. main character energy fr fr 💅

---

🌈 ARGUMENTS 🌈

okay bestie, i have to be so real with you right now. the original page is giving absolutely nothing here, and i'm not about to make up lore that isn't there 😭

• dev — -- undescribed -- (yes literally, the manpage itself says this, i'm not gatekeeping, there's just nothing to gatekeep 🙈)
• reg — -- undescribed --
• value — -- undescribed --

the fact that all three arguments are just sitting there undescribed is so funny to me. no cap. but the names are right there in the synopsis: a struct b43_wldev * called dev, a u16 called reg, and a u16 called value. and those are exactly, character for character, what the original says. 🫶

quick vibe check: this page only ever tells you these are related. it does not tell you what they do, so don't come for me if you want details — go read their own pages. i'm just the messenger 🧚

and that's the page! short, sweet, 16 bits of radio register writing, and a SEE ALSO section longer than the function itself. slay. ⭐
