iio_dummy_write_raw(9)

✨ NAME ✨

okay so this is the iio_dummy_write_raw(9) page from the Kernel API Manual, and it's literally the manual for iio_dummy_write_raw — the data write function. no cap, that's the whole name vibe 💖

🌸 SYNOPSIS 🌸

bestie, here's the signature, copied exactly because we do not mess with code:

int iio_dummy_write_raw (struct iio_dev *indio_dev , struct
       iio_chan_spec const *chan , int val , int val2 , long mask );

💅 ARGUMENTS 💅

• indio_dev — the struct iio_dev associated with this device instance 🫶
• chan — the channel whose data is to be written ✨
• val — first element of value to set (typically INT) 👑
• val2 — second element of value to set (typically MICRO) 🎀
• mask — what we actually want to write as per the info_mask_* in iio_chan_spec 💅

🦋 DESCRIPTION 🦋

heads up, bestie, this is the caveat part and it matters:

Note that all raw writes are assumed IIO_VAL_INT and info mask elements are assumed to be IIO_INT_PLUS_MICRO unless the callback write_raw_get_fmt in struct iio_info is provided by the driver. literally iconic behavior, but also literally the rule 😭
