io_uring_buf_ring_init(3)

💖 io_uring_buf_ring_init(3) 💖

okay bestie, welcome to the liburing corner of the manual, this one's short and sweet and honestly a little iconic for how much it does with so little ✨

🌸 NAME 🌸

io_uring_buf_ring_init — no cap, this is the one that Initialises a buffer ring 🎀

🦋 SYNOPSIS 🦋

#include <liburing.h>

void io_uring_buf_ring_init(struct io_uring_buf_ring *br);

✨ DESCRIPTION ✨

so like. io_uring_buf_ring_init(3) gets br all set up and ready to be used 💅 it's giving "glow up in one function call."

you may call it after io_uring_register_buf_ring(3), but — and this is the important part, do not skip this — it must be called before the buffer ring is used in any other way. any other way. periodt. 🫶

💜 RETURN VALUE 💜

None 💀 yeah, nothing. it returns void. it's a no-notes, no-drama, does-its-job king 👑

👑 NOTES 👑

unless you genuinely need manual setup (iykyk, sometimes you do), the move is to use io_uring_setup_buf_ring(3) instead — it's a simpler way to set up a provided buffer ring and honestly it's just less work for you 🌈
