Python3 os.fstat() Method
Python3 OS File/Directory Methods
Overview
The os.fstat() method is used to return the status of the file descriptor fd, similar to stat().
Available on Unix and Windows.
The structure returned by the fstat method:
st_dev:Device information
st_ino:The i-node value of the file
st_mode:The file information mask, which includes the file's permission information and the file's type information (whether it is a regular file, a pipe file, or another file type)
st_nlink:Number of hard links
st_uid:User ID
st_gid:User group ID
st_rdev:Device ID (if the file is specified)
st_size:File size, in bytes
st_blksize:System I/O block size
st_blocks:The number of 512-byte blocks the file consists of
st_atime:The file's most recent access time
st_mtime:The file's most recent modification time
st_ctime:The modification time of the file status information (not the modification time of the file content)
Syntax
fstat()The method syntax is as follows:
os.fstat(fd)
Parameters
fd-- The file descriptor.
Return Value
Returns the status of the file descriptor fd.
Example
The following example demonstrates the use of the fstat() method:
#!/usr/bin/python3
import os, sys
# 打开文件
fd = os.open( "foo.txt", os.O_RDWR|os.O_CREAT )
# 获取元组
info = os.fstat(fd)
print ("文件信息 :", info)
# 获取文件 uid
print ("文件 UID :%d" % info.st_uid)
# 获取文件 gid
print ("文件 GID :%d" % info.st_gid)
# 关闭文件
os.close( fd)
The output of the above program is:
文件信息 : (33261, 3753776L, 103L, 1, 0, 0,
102L, 1238783197, 1238786767, 1238786767)
文件 UID :0
文件 GID :0
