📦 version 7.3.1, in nixpkgs unstable

💅 v4l2_ctrl_handler_log_status(9) — from the Kernel API Manual, bestie

Okay so real talk: this is a kernel API page, the Kernel API Manual one, for v4l2_ctrl_handler_log_status. It's short. It's sweet. It's giving "one job, does it well." Let's get into it 🎀

✨ NAME ✨

v4l2_ctrl_handler_log_status — literally just logs every single control that the handler owns. That's it. That's the whole gig. 💖

🌸 SYNOPSIS 🌸

void v4l2_ctrl_handler_log_status (struct v4l2_ctrl_handler *hdl , const
char *prefix );

🦋 ARGUMENTS 🦋

  • hdl — the control handler, aka the main character of this whole situation 👑
  • prefix — the prefix you wanna slap in front of the logged control values. Two little rules though, iykyk:
    • if the prefix does not end with a space, then ": " gets added after it
    • if prefix == NULL, then no prefix is used at all — zero, nada, no vibes

🌈 DESCRIPTION 🌈

So this one is for use with VIDIOC_LOG_STATUS. That's the whole assignment, no cap.

And here's the safety net: it does nothing if hdl == NULL. No crash, no drama, no nothing. Just. Nothing. We love a function that knows when to chill 💀✨

👑 SEE ALSO 👑

Bird's-eye view: it's the kernel file ./include/media/v4l2-ctrls.h, plus the entire extended family. The whole group chat, fr fr 🌸:

That's the page, bestie. Mwah. 🫶

And for the cute sign-off: this lil masterpiece lives under ./include/media, dated October 2026, and it goes by v4l2_ctrl_ha...r_log_status(9) — yes the title is literally truncated like that, we don't question it, we stan anyway 💅⭐
