iio_write_channel_attribute(9)

📦 version 7.3.1, in nixpkgs unstable

💫 iio_write_channel_attribute — like, the NAME section, bestie 💫

okay so this is iio_write_channel_attribute(9), straight out of the Kernel API Manual ✨ and it's literally the little guy you call when you want to write values to the device attribute. that's the whole vibe. short, sweet, iconic 💅

🦋 SYNOPSIS 🦋

int iio_write_channel_attribute (struct iio_channel *chan , int val ,
int val2 , enum iio_chan_info_enum attribute );

no cap, that's the exact signature — don't come for me if you typo it, the compiler will absolutely drag you 🙈

🌸 ARGUMENTS 🌸

  • chan — the channel being queried. yes bestie, queried, that's what it says 🫶
  • val — the value being written ✍️
  • val2 — also the value being written. whether val2 even matters at all is lowkey up to the attribute type — it's giving "depends on the situation" energy 💀
  • attribute — the info attribute to be read 👀

🎀 DESCRIPTION 🎀

so like. it returns an error code, or 0. that's it. that's the whole description. main character of a function that knows exactly what it is and refuses to elaborate 💖

fr fr, 0 is the slay outcome and anything else is the error code telling you something went sideways 😭

👑 SEE ALSO 👑
