iio_read_channel_scale(9)

✨ iio_read_channel_scale ✨

okay bestie, welcome to the glow-up era of iio_read_channel_scale — straight out of the Kernel API Manual, section 9 of the kernel API pages. this one's short and sweet and lowkey adorable, let's get into it 🎀

---

💖 NAME 💖

iio_read_channel_scale — read the scale value for a channel. that's it. that's the whole vibe. she reads scales. 👑

---

🌸 SYNOPSIS 🌸

int iio_read_channel_scale (struct iio_channel *chan , int *val , int
*val2 );

like, she takes your channel, and she hands you back two little ints. two. because one int was simply not enough drama. 💅

---

🦋 ARGUMENTS 🦋

• chan — the channel being queried. the main character of this whole operation, honestly. she's the one getting asked the questions. 🫶
• val — first part of the value read back. part one of the duo. 💖
• val2 — second part of the value read back. part two, the sequel, the remix. ✨

🌈 DESCRIPTION 🌈

okay so listen — this is the part you actually need to remember, bestie. 👀

note: the function returns a description of what is in val and val2, and the manpage's own example is IIO_VAL_INT_PLUS_MICRO, which tells us we have a value of val + val2/1e6.

so the return value isn't just "did it work, yes/no" energy — it's literally telling you how to read your own numbers back. it's giving "here's the lore, now go do the math yourself" and honestly? iconic. 🧮🔥
