iio_read_cha...cessed_scale(9)

💖 NAME 💖

okay so this is iio_read_cha...cessed_scale(9), straight out of the Kernel API Manual — the function that reads and scales a processed value. ✨

🦋 SYNOPSIS 🦋

Here’s the exact signature, bestie:

int iio_read_channel_processed_scale (struct iio_channel *chan , int
       *val , unsigned int scale );

🎀 ARGUMENTS 🎀

• chan — the channel being queried. 👑
• val — the value read back. 💖
• scale — the scale factor to apply during the conversion. 💅

✨ DESCRIPTION ✨

It returns an error code or 0. No cap.

This function will read a processed value from a channel. It works like iio_read_channel_processed but also scales with an additional scale factor while attempting to minimize any precision loss. 🫶
