v4l2_ctrl_request_hdl_put(9)

📦 version 7.3.1, in nixpkgs unstable

💅 v4l2_ctrl_request_hdl_put — the Kernel API Manual, bestie edition 🎀

okay so real talk: this is a page from the Kernel API Manual (yes, the v4l2_ctrl_request_hdl_put(9) one, she's famous), and honestly she's short but she matters. Let's get into it ✨

🌸 NAME 🌸

v4l2_ctrl_request_hdl_put — put the control handler 🫶

Like, "put it back." Release it. Let it go. Free the girl.

✨ SYNOPSIS ✨

void v4l2_ctrl_request_hdl_put (struct v4l2_ctrl_handler *hdl );

That's the whole vibe. One function, one pointer, returns nothing (it's void, she gives nothing and that's her right 👑).

🦋 ARGUMENTS 🦋

  • hdl — put this control handler. That's it. That's the argument. You hand her the handler and she puts it. 💖

🌈 DESCRIPTION 🌈

okay so what does she actually do? This function releases the control handler that you previously obtained from v4l2_ctrl_request_hdl_find. That's the whole story, no cap.

So like — you went and found a handler earlier with v4l2_ctrl_request_hdl_find, and now you're done with it, so you pass it here and she releases it. It's giving "borrow your hoodie, give it back" energy 🧚

fr fr bestie, this is the cleanup half of a pair. The original text literally says "this function released the control handler previously obtained from' v4l2_ctrl_request_hdl_find" — yes there's a lil rogue apostrophe in there, we love her anyway 🙈 don't come for her, she's doing her best.

🔥 SEE ALSO 🔥

okay this is the part where she lists literally everyone she knows at the function party and honestly? iconic. Go say hi to all of them, they're in the kernel file ./include/media/v4l2-ctrls.h 💜

mwah 💋 that's the page. Sourced straight from ./include/media, dated October 2026, and it's v4l2_ctrl_request_hdl_put(9) — she came, she released the handler, she left. slay 💅✨🎀
