如何使用readdir获取文件修改时间

        // 构建文件的完整路径
        char path[PATH_MAX];

        if (stat(path, &file_stat) == -1) {
            perror("stat");
            continue;

        // 打印文件名和修改时间
        char time_buf[26];
        ctime_r(&file_stat.st_mtime, time_buf);

        printf("%s - Modified: %s", entry->d_name, time_buf);
    }

    // 关闭目录
    closedir(dir);

    return EXIT_SUCCESS;
