【C/C++文件处理系列】通过stat()函数获取struct stat结构的信息_c/c++ stat()

【stat】

函数原型：

stat() stats the file pointed to by path and fills in buf

获取指定路径的文件信息并保存到struct stat类型的结构体中

int stat(const char *path, struct stat *buf);

struct stat 结构体 详见struct stat定义链接

代码实现

#include <sys/stat.h>
#include <sys/types.h>
using namespace std;
int main()
{
   int abc;
   struct stat mystat;
   stat("l_stat.cpp",&mystat);
 
   cout<<"st_dev is:"<<mystat.st_dev<<endl;
   cout<<"st_ino is:"<<mystat.st_ino<<endl;
   cout<<"st_mode is:"<<mystat.st_mode<<endl;
   cout<<"st_nlink is:"<<mystat.st_nlink<<endl;
   cout<<"st_uid si:"<<mystat.st_uid<<endl;
   cout<<"st_gid is:"<<mystat.st_gid<<endl;
   cout<<"st_rdev is:"<<mystat.st_rdev<<endl;
   cout<<"st_size is:"<<mystat.st_size<<endl;
   cout<<"st_blksize is:"<<mystat.st_blksize<<endl;
   cout<<"st_atime is:"<<mystat.st_atime<<endl;
   cout<<"st_mtime is:"<<mystat.st_mtime<<endl;
   cout<<"st_ctime is :"<<mystat.st_ctime<<endl;
 
}

编译执行
