io_uring_unregister_napi(3)

💖 io_uring_unregister_napi — ok bestie let's talk NAPI 💖

So this one's from the liburing Manual, and honestly? It's giving "small function, big cleanup energy." ✨

🌸 NAME 🌸

io_uring_unregister_napi — unregister NAPI busy poll settings

Like. It literally does what it says on the tin, and we love that for it. 💅

🦋 SYNOPSIS 🦋

#include <liburing.h>

int io_uring_unregister_napi(struct io_uring *ring,
                             struct io_uring_napi *napi)

Two args, no drama. ring is your ring, napi is your napi struct. Slay. 🎀

✨ DESCRIPTION ✨

okay so here's the tea ☕

The io_uring_unregister_napi(3) function unregisters the NAPI busy poll settings for subsequent operations.

That's it. That's the whole vibe. You had NAPI busy poll settings registered, and now you're like "actually, no, we're done here" and this function handles the goodbye. 👋 Subsequent operations don't get those settings anymore. Periodt.

👑 RETURN VALUE 👑

• On success, io_uring_unregister_napi(3) returns 0. 🎉
• On failure, they return -errno. 😭
• It also updates the napi structure with the current values.

not me checking the return value every single time, because -errno will absolutely humble you if you ignore it 🙈

🫶 SEE ALSO 🫶

...okay so the original page doesn't have a SEE ALSO section, and I'm not about to invent one, because rule number one is keep every detail, add nothing. No cap. 💜

that's the whole page bestie, go unregister those NAPI busy poll settings and live your main character life 🌈💖
