如何构建liburing

sudo apt-get install -f

sudo ldconfig /usr/local/lib

#include <liburing.h>
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>

#define BUF_SIZE 4096

int main(int argc, char *argv[]) {
    struct io_uring ring;

    char buf[BUF_SIZE];
    int fd;

    if (argc < 2) {
        fprintf(stderr, "Usage: %s <file>\n", argv[0]);
        return 1;
    }

    fd = open(argv[1], O_RDONLY);
    if (fd < 0) {
        perror("open");
        return 1;
    }

    io_uring_queue_init(32, &ring, 0);

    sqe = io_uring_get_sqe(&ring);
    io_uring_prep_read(sqe, fd, buf, BUF_SIZE, 0);
    io_uring_submit(&ring);

    cqe = io_uring_wait_cqe(&ring);
    if (cqe->res < 0) {
        fprintf(stderr, "read error: %s\n", strerror(-cqe->res));
    } else {
        printf("Read %d bytes\n", cqe->res);
    }

    io_uring_cqe_seen(&ring, cqe);
    close(fd);
    io_uring_queue_exit(&ring);

    return 0;
}

gcc -o async_read async_read.c -luring
./async_read /path/to/file
