💅 iio_find_channel_from_si(9) — get channel from its scan index 💅

okay so bestie, welcome to the Kernel API Manual page for iio_find_channel_from_si(9). This is the “get channel from its scan index” girly, and she is lowkey iconic in a very specific kernel-lookup way. We are keeping every single detail exactly where it belongs, no cap. ✨

💖 NAME 💖

iio_find_channel_from_si — get channel from its scan index.

---

✨ SYNOPSIS ✨

const struct iio_chan_spec * iio_find_channel_from_si (struct iio_dev
       *indio_dev , int si );

---

🎀 ARGUMENTS 🎀

• indio_dev — the device. That’s the device bestie in question. 🫶
• si — scan index to match. Like, the exact scan-index vibe we are hunting for. 🔍

---

🦋 RETURN 🦋

Constant pointer to iio_chan_spec, if scan index matches, and NULL on failure. So if the scan index matches, you get the constant pointer; if not, NULL is the “nope, not today” answer. 💀
