stat( ) 函数

#include<sys/stat.h>

#include<iostream>

#include<ctime>

using namespace std;



int main()

{

    struct stat buf;

    int result;

    result=stat("1.mp3",&buf);//stat（）函数获取文件状态，成功返回0，失败返回-1。

    if(result!=0)

                 perror("Failed !");

    else

    {

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

        cout<<"time of creation of the file"<<"\t"<<ctime(&buf.st_ctime)<<endl;

        cout<<"time of last modification of the file:"<<"\t"<<ctime(&buf.st_mtime)<<endl;

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

    }

    getchar();

    return 0;

}

OUTPUT:

size of the file in bytes:      6083826

time of creation of the file    Mon Dec 20 15:44:58 2010

 

time of last modification of the file:  Sun Dec 19 20:37:57 2010

 

time of last access of the file:        Mon Dec 20 15:44:58 2010

文件属性： 

（该文件夹中不存在2.MP3，所以：

#include<sys/stat.h>

#include<iostream>

#include<ctime>





using namespace std;



int main()

{

    struct stat buf;

    int result;

    result=stat("2.mp3",&buf);//stat（）函数获取文件状态，成功返回0，失败返回-1。

    if(result!=0)

                 perror("Failed !");

    else

    {

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

        cout<<"time of creation of the file"<<"\t"<<ctime(&buf.st_ctime)<<endl;

        cout<<"time of last modification of the file:"<<"\t"<<ctime(&buf.st_mtime)<<endl;

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

    }

    getchar();

    return 0;

}

output：

Failed !: No such file or directory
