struct stat结构体的详解和用法

//! 需要包含de头文件

#include <sys/types.h>

#include <sys/stat.h> 

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 - */

};

#include <iostream>

#include <ctime>

#include <sys/types.h>

#include <sys/stat.h> 

using namespace std; 

int
main ()
{
    struct stat buf;

    int result;

    result = stat ("./Makefile", &buf);

    if (result != 0)
      {
          perror ("Failed ^_^");
      }
    else
      {

          //! 文件的大小，字节为单位

          cout << "size of the file in bytes: " << buf.st_size << endl;

          //! 文件创建的时间

          cout << "time of creation of the file: " << ctime (&buf.st_ctime) <<

              endl;

          //! 最近一次修改的时间

          cout << "time of last modification of the file: " <<

              ctime (&buf.st_mtime) << endl;

          //! 最近一次访问的时间

          cout << "time of last access of the file: " << ctime (&buf.st_atime)

              << endl;
      }

    return 0;

}

$ ./test


size of the file in bytes: 36


time of creation of the file: Sun May 24 18:38:10 2009


time of last modification of the file: Sun May 24 18:38:10 2009


time of last access of the file: Sun May 24 18:38:13 2009
