struct stat结构体的详解和用法-ag真人游戏

//! 需要包含de头文件
#include 
#include  
int stat(const char *filename, struct stat *buf); //! prototype,原型 
struct stat
{
    dev_t       st_dev;     /* id of device containing file -文件所在设备的id*/
    ino_t       st_ino;     /* inode number -inode节点号*/
    mode_t      st_mode;    /* protection -保护模式?*/
    nlink_t     st_nlink;   /* number of hard links -链向此文件的连接数(硬连接)*/
    uid_t       st_uid;     /* user id of owner -user id*/
    gid_t       st_gid;     /* group id of owner - group id*/
    dev_t       st_rdev;    /* device id (if special file) -设备号，针对设备文件*/
    off_t       st_size;    /* total size, in bytes -文件大小，字节为单位*/
    blksize_t   st_blksize; /* blocksize for filesystem i/o -系统块的大小*/
    blkcnt_t    st_blocks;  /* number of blocks allocated -文件所占块数*/
    time_t      st_atime;   /* time of last access -最近存取时间*/
    time_t      st_mtime;   /* time of last modification -最近修改时间*/
    time_t      st_ctime;   /* time of last status change - */
