💅 dprtc_close(9) — the kernel API manual, bestie edition

Okay so real talk: this is a page from the Kernel API Manual for dprtc_close, and it's lowkey one of those functions that does exactly one thing and does it iconically. Sit down, grab a lil snack 🍓, and let's get into it.

✨ NAME ✨

dprtc_close — close the control session of the object

That's it. That's the whole vibe. It shuts the door on your session. 🚪💨

🦋 SYNOPSIS 🦋

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

Three args, one int coming back at you. No cap, that's the whole signature. 🌸

🎀 ARGUMENTS 🎀

  • mc_io — Pointer to MC portal's I/O object. Like, this is your connection to the MC portal itself, so don't be out here passing garbage, bestie 🫶
  • cmd_flags — Command flags; one or more of 'MC_CMD_FLAG_'. Yes, one or more — you can stack 'em. 👑
  • token — Token of DPRTC object. This is the token that identifies your object. It's giving VIP wristband at the club. 🎟️

🌈 DESCRIPTION 🌈

So here's the tea ☕: after this function is called, no further operations are allowed on the object without opening a new control session.

Read that again. No further operations. Zero. None. Nada. You closed the session, so the session is closed — that's the whole deal. If you wanna come back and do stuff on this object, you gotta call dprtc_open(9) again and start fresh, like a brand new era. ✨

It's literally the "and that's on periodt, we're done here" of kernel functions. 💅

💀 RETURN 💀

The original page doesn't document any return values here — the section is there but it's empty, so I'm not gonna make up numbers and lie to you. Insert your own dramatic pause. 😭

🔥 SEE ALSO 🔥

Kernel file: ./drivers/net/ethernet/freescale/dpaa2/dprtc.c

The whole friend group, in order:

Like, if dprtc_close is the goodbye, dprtc_open is the "heyyy bestie" — they're a package deal, iykyk. 🧚

Heads up babes: once dprtc_close has run, any further operations on the object must wait for a new control session. That's not a suggestion, that's the rule. 🚨

Mwah 💖 this page lives at ./drivers/net/ethernet/freesca... in the Kernel API Manual, dated October 2026, and it's the dprtc_close(9) girlies' official documentation. Go forth and close your sessions responsibly. 🎀🦋
