πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… NAME πŸ’…

v4l2_ctrl_log_status β€” bestie, it's the helper function to implement the %VIDIOC_LOG_STATUS ioctl ✨

(also hi, you're reading the Kernel API Manual entry for it, welcome 🫢)


✨ SYNOPSIS ✨

int v4l2_ctrl_log_status (struct file *file , void *priv );

🌸 ARGUMENTS 🌸

  • file β€” pointer to struct file. yeah. that one. the filehandle, the main character πŸ’…
  • priv β€” lowkey unused 😭 it's just sitting there existing purely for compatibility with the arguments expected by struct v4l2_ioctl_ops.vidioc_log_status. iconic of it honestly, showing up to the function and doing nothing πŸŽ€

πŸ¦‹ DESCRIPTION πŸ¦‹

So the way this works: you can use this as your vidioc_log_status function, and what it does is literally just dump all the controls associated with the filehandle. that's it. that's the whole vibe. no cap πŸ”₯

like it's giving "walk in, dump every control tied to this filehandle, leave" β€” and honestly? slay. sometimes the simplest helper is the most iconic one πŸ‘‘
