ca8210_test_int_ioctl(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ca8210_test_int_ioctl — the ca8210_test_int_ioctl(9) girlie pop-off 💖

okay so bestie, welcome to the Kernel API Manual entry for ca8210_test_int_ioctl(9) — yes that's the whole name, it's giving "my parents named me after a stack trace" but honestly? iconic. this is the little handler that a process in userspace calls when it wants to enact an arbitrary action. yes. arbitrary. as in you pick the action. main character energy fr fr 🌈

✨ NAME ✨

ca8210_test_int_ioctl — called by a process in userspace to enact an arbitrary action 💅

like. it's the doorbell. userspace rings it, and whatever it asked for, happens. no cap.

🎀 SYNOPSIS 🎀

long ca8210_test_int_ioctl (struct file *filp , unsigned int ioctl_num ,
       unsigned long ioctl_param );

that's the whole vibe check right there — one function, three little arguments, returns a long. she's concise. she's booked and busy. ✨

🌸 ARGUMENTS 🌸

  • filp — file interface 🫶 this is the file handle situation, the "who's calling" of it all.
  • ioctl_num — which action to enact 👑 you choose the action, bestie, that's literally the whole point.
  • ioctl_param — arbitrary parameter for the action 🎁 it's a lil gift box for whatever the action needs. arbitrary. keep that word in your heart.

⭐ RETURN ⭐

status 💀 that's it. that's the answer. it gives you a status. queen of not over-explaining.

🦋 SEE ALSO 🦋

okay this next part is a lot — like, this function has more friends than anyone i know — but i'm not skipping a single one because every crumb matters 🙈 here's the whole guest list, starting with the kernel file itself:

  • Kernel file ./drivers/net/ieee802154/ca8210.c 🧚

and then, in order, the entire extended universe:

like i said. the whole friend group. obsessed. 🔥

lowkey reminder bestie: "arbitrary action" means arbitrary — whatever ioctl_num says goes. this is a test interface, so treat it with the respect of something that straight-up does what it's told. 💀

and that's the page!! mwah 🫶 before i go — this lil beauty lives in ./drivers/net/ieee802154, it's dated October 2026, and it's formally known as ca8210_test_int_ioctl(9). stay slay, stay in userspace, and don't touch filp. 💜🍓
