给出一个文件（文件、文件夹），一旦给出pathname,stat函数就返回与此命名文件有关的信息结构，fstat函数获取已在描述符fields上打开文件的有关信息。lstat函数类似于stat.但是当命名的文件是一个符号链接时，lstat返回该符号链接的有关信息，而不是由该符号链接引用文件的信息。第二个参数buf是指针，它指向一个我们必须提供的结构，这些函数填写由buf指向的结构。该结构的实际定义可能随实现有所不同.

int stat(const char *restrict pathname,struct stat *restrict buf);
int fstat(int fields,struct stat *buf);
int lstat(const char *restrict pathname,struct stat *restrict buf);
int chmod(const char *, mode_t);
int fchmod(int, mode_t);
int fstat(int, struct stat *);
int lstat(const char *restrict, struct stat *restrict);
int mkdir(const char *, mode_t);
int mkfifo(const char *, mode_t);
int mknod(const char *, mode_t, dev_t);
int stat(const char *restrict, struct stat *restrict);
mode_t umask(mode_t);
//返回值:若成功则返回0,失败则返回-1

sys/stat.h定义的结构体如下：

struct stat{ mode_t st_mode; //文件类型和权限信息ino_t st_ino; //i结点标识dev_t st_dev; //device number (file system)dev_t st_rdev; //device number for special filesnlink_t st_nlink; //符号链接数uid_t st_uid; //用户IDgid_t st_gid; //组IDoff_t st_size; //size in bytes,for regular filestime_t st_atime; //最后一次访问的时间time_t st_mtime; //文件内容最后一次被更改的时间time_t st_ctime; //文件结构最后一次被更改的时间blksize_t st_blksize; //best I/O block sizeblkcnt_t st_blocks; //number of disk blocks allocated
};

判断文件类型的函数：

文件类型：
普通文件，S_ISREG();
目录文件，S_ISDIR();
块特殊文件，字符特殊文件，套接字，
FIFO，S_ISFIFO();符号链接.
文件类型信息包含在stat结构的st_mode成员中,可以用如下的宏确定文件类型,这些宏是stat结构中的st_mode成员.
S_ISCHR();S_ISBLK();S_ISLNK();S_ISSOCK()

编写一个简单的程序，用整形输出结构体变量

#include<sys/stat.h>
/*文件属性*/
#include<stdio.h>int main(int argc,char* argv[])
{struct stat buf;stat("Demo.c", &buf);printf("st_mode = %d\n", buf.st_mode);printf("st_ino = %d\n", buf.st_ino);printf("st_dev = %d\n", buf.st_dev);printf("st_rdev = %d\n", buf.st_rdev);printf("st_nlink = %d\n", buf.st_nlink);printf("st_uid = %d\n", buf.st_uid);printf("st_gid = %d\n", buf.st_gid);printf("st_size = %d\n", buf.st_size);printf("st_atime = %d\n", buf.st_atime);printf("st_mtime = %d\n", buf.st_mtime);printf("st_ctime = %d\n", buf.st_ctime);printf("st_blksize = %d\n", buf.st_blksize);printf("st_blocks = %d\n", buf.st_blocks);char *ptr;if (S_ISREG(buf.st_mode))ptr="普通文件";if (S_ISDIR(buf.st_mode))ptr="目录";printf("%s\n",ptr);
}

编译与运行：

$ gcc Demo.c
$ ./a.out
st_mode = 33188
st_ino = 1081915443
st_dev = 2065
st_rdev = 0
st_nlink = 1
st_uid = 532
st_gid = 500
st_size = 2895
st_atime = 1517745734
st_mtime = 1517745603
st_ctime = 1517745603
st_blksize = 4096
st_blocks = 8
普通文件

随便给一个CentOS的sys.stat.h文件（/usr/include/sys/stat.h）
