ms_sensors_write_resolution(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ms_sensors_write_resolution(9) — like, the kernel API manual, bestie ✨

Okay so this is ms_sensors_write_resolution(9) from the Kernel API Manual, and no cap, it's a lil baby function that does exactly one thing and does it beautifully. Let's get into it 🎀

🌸 NAME 🌸

ms_sensors_write_resolution — the set-resolution function. That's it, that's the whole vibe. She's the "set resolution" function, periodt ✨

🦋 SYNOPSIS 🦋

ssize_t ms_sensors_write_resolution (struct ms_ht_dev *dev_data , u8 i
);

Yeah, that's the whole signature — two args, one return value, no drama 💅

🎀 ARGUMENTS 🎀

  • dev_data — a pointer to your temperature/humidity device data. Like, the whole device's little info bundle 🫶
  • i — the resolution index you wanna set. It's a u8, so like... small numbers only, bestie 🔥

✨ DESCRIPTION ✨

So here's the tea: this function programs the appropriate resolution based on the index you hand it — that's i — and it does this when user space sets the samp_freq channel. The way it just... knows what resolution goes with what index? Iconic. Main character energy fr fr 👑

And who is this for, you ask? She's serving TSYS02D, HTU21, and MS8607 chipsets specifically. If you're not one of those three, this function is not your girl, sorry not sorry 🙈

⭐ RETURN ⭐

  • 0 on success — slay, you ate 💖
  • a negative errno otherwise — not the vibe, but at least it tells you 😭

💀 SEE ALSO 💀

The kernel file itself, in all its glory:

And the whole friend group — the entire ms_sensors squad, lowkey a whole family reunion 🧚:

ngl bestie, if you gotta set a resolution on a TSYS02D, an HTU21, or an MS8607, this is the function. Go off 💜
