dpio_close(9)

📦 version 7.3.1, in nixpkgs unstable

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

Okay so real talk, the manpage is literally called dpio_close(9) and it lives in the Kernel API Manual. What does it do? It closes the control session of the object. That's it. That's the whole name section. A closer. An icon. 🎀

✨ NAME ✨

dpio_close — Close the control session of the object

🦋 SYNOPSIS 🦋

int dpio_close (struct fsl_mc_io *mc_io , u32 cmd_flags , u16 token );

Yes bestie, the spaces before the commas are exactly how it's written, I don't make the rules, I just serve them 💅

🌸 ARGUMENTS 🌸

Three args, three little besties, let's meet them:

  • mc_io — Pointer to MC portal's I/O object. It's giving "your portal pass", like you literally cannot get in without it 🫶
  • cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. Note the quote situation: the page literally says one or more of 'MC_CMD_FLAG_', so that's what you're getting from me, no cap.
  • token — Token of DPIO object. Your little DPIO hall pass so the kernel knows which object you're closing the control session on 👑

💀 RETURN 💀

So… the RETURN section on this page is genuinely empty. Nothing. Not a value, not an exit status, not a single crumb of documentation 😭 The original just goes straight from ARGUMENTS to SEE ALSO like nothing happened. I'm not gonna invent a return value for you — that's not my main character energy, that's fanfic. If you need it, go read the source (see below).

🔥 SEE ALSO 🔥

The kernel file lives at ./drivers/soc/fsl/dpio/dpio.c — go say hi to it 🧚

And these siblings, all in section 9, all iconic:

Like honestly, dpio_open(9) and dpio_close(9) are the original "you're my bestie, you're my enemy" duo 💜

Lowkey a tiny page, highkey complete — every arg, every flag, every SEE ALSO reference is here, so you're not missing a thing 🍓

Okay byeee, this lil page comes to you from ./drivers/soc/fsl/dpio, dated October 2026, and its header/footer name is dpio_close(9) — slay, stay hydrated, read your manpages, periodt 💖✨
