iio_scan_mask_set(9)

✨ iio_scan_mask_set ✨

okay so bestie, welcome to the iio_scan_mask_set(9) page from the Kernel API Manual — this is the little function that sets a particular bit in the scan mask 💅 and we're gonna get into it fr fr.

🌸 NAME 🌸

iio_scan_mask_set — set particular bit in the scan mask 🎀

🦋 SYNOPSIS 🦋

int iio_scan_mask_set (struct iio_dev *indio_dev , struct iio_buffer
*buffer , int bit );

like literally that's the whole signature, no cap 🫶

💖 ARGUMENTS 💖

• indio_dev — the iio device 👑 that's your main character right there
• buffer — the buffer whose scan mask we are interested in 🧚 (yes, this buffer's mask, we're being specific)
• bit — the bit to be set. periodt. 💅

🔥 DESCRIPTION 🔥

okay so here's the vibe check: at this point we have no way of knowing what other buffers might request 😭 — like we literally cannot see them, they haven't texted back — hence this code only verifies that the individual buffer's request is plausible ✨. that's it. that's the whole check. don't come for it, it's doing its best 💀

ngl bestie, "plausible" is doing a LOT of heavy lifting in that sentence and you should not read it as "guaranteed correct" 🙈
