iio_read_min_channel_raw(9)

🌸 iio_read_min_channel_raw(9) 🌸

okay bestie, welcome to the Kernel API Manual — the function on the cover is iio_read_min_channel_raw(9), and she is main character energy 💅✨

💖 NAME 💖

iio_read_min_channel_raw — read the minimum available raw value from a given channel, i.e. the minimum possible value. no cap, that's the whole vibe check 📉💖

✨ SYNOPSIS ✨

the signature, copied exactly so nobody comes for me:

int iio_read_min_channel_raw (struct iio_channel *chan , int *val );

🫶 ARGUMENTS 🫶

• chan — the channel being queried. that's the one you're asking, bestie 👀
• val — value read back. this is where the value comes back to you 🎀

🦋 DESCRIPTION 🦋

⚠️ note, bestie: if you need standard units, raw reads from iio channels need the offset (default 0) and scale (default 1) applied as (raw + offset) * scale. do not skip this — it's giving "math check before you flex" 😭📐
