iio_active_scan_mask_index(9)

🌸 NAME 🌸

okay so bestie, this is iio_active_scan_mask_index(9), straight outta the Kernel API Manual, and it's here to do one iconic little job: get the index of the active scan mask inside the available scan masks array. That's the whole vibe. 💅✨

✨ SYNOPSIS ✨

int iio_active_scan_mask_index (struct iio_dev *indio_dev );

🎀 ARGUMENTS 🎀

• indio_dev — the IIO device containing the active and available scan masks. It's giving main character struct energy, and it's literally the thing you pass in. 🫶

💅 RETURN 💅

It returns the index. But if active_scan_mask is not set? Boom: -EINVAL. No index, just a little error moment. 😭
