struct stat 的用法

#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; }
