okay so bestie, this is a page straight out of the liburing Manual and it's about ONE little function that does ONE little thing and honestly? we love a specialist 💅

🌸 NAME 🌸

io_uring_prep_uring_cmd128 — get a uring_cmd request all set up and ready to slay

🎀 SYNOPSIS 🎀

#include <liburing.h>

void io_uring_prep_uring_cmd128(struct io_uring_sqe *sqe,
                                           int cmd_op,
                                           int fd);

🦋 DESCRIPTION 🦋

so the function io_uring_prep_uring_cmd128(3) is here to prep a uring_cmd request — and not just any request, a file-descriptor-specific one, for a 128 byte submission queue entry. iykyk 🌈

basically it takes your submission queue entry sqe and sets it up so it uses the filedescriptor fd to send the file descriptor specific cmd_op. that's the whole vibe. it's giving "matchmaker, but for fds and ops" 🫶

oh and also? the reserved fields get initialized to 0. iconic. the rest of it though — any operation-specific fields on the submission queue entry — that's on you, bestie. the caller has to set those up. no one else is gonna do it. periodt. 💅

💖 RETURN VALUE 💖

None. literally nothing. zero. it's void-coded 😌

🔥 ERRORS 🔥

None. not a single one. no notes. 💀
