stat.c

简介

//! 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 - */
};

using namespace std;

 

int main ()

    else

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

    }

    return 0;
