📦 version 7.3.1, in nixpkgs unstable

🎀 NAME 🎀

okay so bestie, this is the Kernel API Manual entry for iio_backend_debugfs_print_chan_status, and its whole job is literally: print channel status. no cap. 💅✨

✨ SYNOPSIS ✨

ssize_t iio_backend_debugfs_print_chan_status (struct iio_backend *back
, unsigned int chan , char *buf , size_t len );

🌸 ARGUMENTS 🌸

vibe check the parameters, bestie:

  • back — Backend device. Your main-character backend. 👑
  • chan — Channel number. The specific channel, iykyk. 🔢
  • buf — Buffer where to print the status. This is where the status tea goes. 🫶
  • len — Available space. How much room there is in buf. 📏

🦋 DESCRIPTION 🦋

One usecase where this is useful is for testing test tones in a digital interface and "ask" the backend to dump more details on why a test tone might have errors.

It’s giving “debugging with receipts,” lowkey. 💀✨

🔥 RETURN 🔥

Number of copied bytes on success, negative error code on failure. That’s it, that’s the return vibe. 💖
