iio_for_each_active_channel(9)

💅 iio_for_each_active_channel — from the Kernel API Manual (9) 🎀

okay so bestie, welcome to the iio_for_each_active_channel(9) page, straight outta the Kernel API Manual. this one's short and sweet, so grab your lil strawberry drink 🍓 and let's get into it.

✨ NAME ✨

iio_for_each_active_channel — iterated over active channels 💫

yes the original says "iterated", not "iterate". we respect the original's grammar choices here, no cap.

---

🌸 SYNOPSIS 🌸

iio_for_each_active_channel (indio_dev , chan );

that's the whole vibe. two args, in that order, spaces included, we do not touch the spaces. 💅

---

🦋 ARGUMENTS 🦋

• indio_dev — the IIO device. that's the main character right there 👑
• chan — holds the index of the enabled channel. it's giving "the lil number that tells you which one we're on" ✨
