📦 version 7.3.1, in nixpkgs unstable

💖 iio_read_channel_processed 💖

okay so this is a page from the Kernel API Manual — yes bestie, the actual kernel docs, we're in the big leagues now — and it's all about pulling a processed value out of an IIO channel. slay.

✨ NAME ✨

iio_read_channel_processed — read a processed value from a given channel 🎀

✨ SYNOPSIS ✨

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

✨ ARGUMENTS ✨

  • chan — the channel being queried 🫶
  • val — the value that gets read back 💫

✨ DESCRIPTION ✨

So this one returns an error code, or 0. that's the contract, no cap.

What it does: it reads a processed value from a channel. and "processed" is the whole vibe here — it means the value comes back with the correct unit, not some device-internal representation that only the hardware understands 😭 like, actual usable numbers.

and here's the clever part 👑 if the device doesn't support reporting a processed value, the function doesn't just give up — it queries the raw value plus the channel's scale and offset, and does the appropriate transformation for you. it's giving main character energy, it's giving "i'll handle it myself". 💅
