sca3000_write_event_value(9)

💅 sca3000_write_event_value — a kernel API manual moment

okay so bestie, you're looking at sca3000_write_event_value(9) from the Kernel API Manual, and honestly? it's giving "small function, big responsibility." this one is literally all about control of threshold and period. that's the whole vibe. 🎀

✨ SYNOPSIS ✨

int sca3000_write_event_value (struct iio_dev *indio_dev , const struct
       iio_chan_spec *chan , enum iio_event_type type , enum
       iio_event_direction dir , enum iio_event_info info , int val , int val2
       );

like, yes, that's a lot of parameters. breathe. we're gonna go through every single one, no cap. 🫶

🌸 ARGUMENTS 🌸

• indio_dev — the device instance's own specific IIO information. it's the "which device are we even talking about" of it all.
• chan — the description of the channel whose event is being configured. you gotta know which channel you're messing with, periodt.
• type — the type of event being configured. here it's magnitude rising, because literally everything else is read only. that's not a suggestion, that's just the rules. 💅
• dir — the direction of the event. here: rising. (here too, bestie, keep up 😭)
• info — what info about the event are we configuring? here it's the threshold only. that's the whole assignment.
• val — the integer part of the value being written.. (yes, two dots, that's how the original rolls, don't come for me 🙈)
• val2 — the non integer part of the value being written. here it's always 0. iconic, unchanging, reliable. ✨

ngl, the "here always 0" and "here rising" energy is giving this function is lowkey specialized, so don't go expecting it to do the other stuff — the manpage is very clear that it doesn't. 💀
