io_uring_unregister_buffers(3)

💖 io_uring_unregister_buffers — bestie edition 💖

okay so this is a liburing manual page, bestie. it lives in section 3 of the manual, and it's all about ✨ undoing ✨ a thing you did earlier. the function is called io_uring_unregister_buffers. say it with me. iconic name, honestly.

✨ NAME ✨

io_uring_unregister_buffers — unregister buffers for fixed buffer operations 🎀

like, it takes your fixed buffers off the guest list. that's the whole vibe.

🌸 SYNOPSIS 🌸

#include <liburing.h>

int io_uring_unregister_buffers(struct io_uring *ring);

there it is. one include, one function, one struct io_uring *ring pointer. clean. minimal. main character energy. 💅

🦋 DESCRIPTION 🦋

okay so listen. the io_uring_unregister_buffers(3) function unregisters the fixed buffers that were previously registered to the ring.

that's it. that's the function. it's the uno reverse card 🃏 for buffer registration — you registered them, and now you're taking them back off the list. no cap.

💀 reminder that it's the fixed buffers previously registered to the ring that get unregistered. it's not inventing new ones, it's not guessing, it's just un-doing the registration you already did.

🌈 RETURN VALUE 🌈

• success — io_uring_unregister_buffers(3) returns 0 ✨ and you may celebrate 🎉
• failure — it returns -errno 😭 so yeah, negative errno, go read your errno and find out what went wrong

🫶 fr fr, 0 means slay, -errno means read the error and cope.

👑 SEE ALSO 👑

• io_uring_register_buffers(3) — the other half of this situationship 💞 (register them there, unregister them here, it's giving balance)

and that's the whole page, bestie!! 🎀 this little gem comes to you from liburing-2.1, dated November 15, 2021, and it's the liburing Manual, section 3 — same title up top, same title at the bottom, because symmetry is also main character energy. go unregister those buffers, you've got this 💖✨🦋
