ioctl_done(9)

💅 ioctl_done — the Kernel API Manual moment 🎀

okay so bestie, we're in the Kernel API Manual today and the star of the show is ioctl_done(9). Buckle up, it's a short one but it's iconic. ✨

---

✨ NAME ✨

ioctl_done — the callback from the low level driver 🫶

Like, the whole vibe is: the low-level driver calls back to say "hey, I'm done". That's it. That's the function. 💖

---

🌸 SYNOPSIS 🌸

void ioctl_done (uioc_t *kioc );

Look at that signature. void return, one pointer argument, no drama. Lowkey the cleanest little prototype you've ever seen. 💅

---

🦋 ARGUMENTS 🦋

• kioc — the completed ioctl packet 💌

fr fr, that's the whole thing — kioc is a uioc_t * and it's the completed ioctl packet. Not a pending one, not a half-done one. Completed. She's done her job and she's serving. 👑

💜 SEE ALSO 💜

okay this is the part where the manpage goes full main-character and name-drops the entire megaraid friend group 😭 and you know I'm listing every single one, no cap:

ngl bestie, this page is short but she's perfect. Read the SEE ALSO list, meet the whole crew, and go be a callback. 🌈
