✨ io_uring_sqe_set_buf_group ✨

okay bestie, welcome to the liburing manual, page for io_uring_sqe_set_buf_group(3) 💖 this one's short and sweet, like a little snack, but it's lowkey important if you're doing multishot stuff, so pay attention 🫶

🌸 NAME 🌸

io_uring_sqe_set_buf_group — set buf group for submission queue event 👑

🎀 SYNOPSIS 🎀

#include <liburing.h>

void io_uring_sqe_set_buf_group(struct io_uring_sqe *sqe,
                                int bgid);

no return value, no drama, just vibes ✨

🦋 DESCRIPTION 🦋

so the way this works is, io_uring_sqe_set_buf_group(3) sets the associated buf_group of the sqe to bgid. that's it. that's the whole job. she's a one-task queen 💅

and when do you use her? okay so after the caller has requested a submission queue entry (SQE) with io_uring_get_sqe(3), they can associate a buf_group with the SQE used for multishot operations 🔥 like, that's the moment. you got your SQE, now you're telling it which buf group it belongs to, and multishot is gonna eat that up fr fr.

not me explaining a two-line function like it's a whole personality, but honestly? it deserves the spotlight 💀

🌈 RETURN VALUE 🌈

None 💖 nothing. zero. she gives you nothing back and honestly that's iconic of her. no error code, no exit status, no nothing. just set and go ✨
