Python os.fpathconf() Method with example

Hello dear readers! Welcome back to another section of our tutorial on Python. In this tutorial guide, we are going to be studying about the Os fpathconf() method.

The Python os fpathconf() method returns system configuration data that is relevant to an open file. This variable is very similar to the unix system call fpathconf() and also accept the similar arguments.


Below is the syntax for Python Os fpathconf() method -

os.fpathconf(fd,   name);

Parameter Details

  • fd - It is the file descriptor for which system configuration information is to be returned.
  • name - This specifies the config value to retrieve; it may be a string, which is the name of a defined system value; these names are been specified in a number of standards (POSIX.1, Unix 95, Unix 98).

Return Value

This returns system configuration information relevant to an open file.


The following below is a simple example -


import os, sys

# Open a file
fd = os.open( "foo.txt", os.O_RDWR|os.O_CREAT )

print "%s" % os.pathconf_names

# Now get maximum number of links to the file.
no = os.fpathconf(fd, 'PC_LINK_MAX')
print "Maximum number of links to the file. :%d" % no

# Now get maximum length of a filename
no = os.fpathconf(fd, 'PC_NAME_MAX')
print "Maximum length of a filename :%d" % no

# Close opened file
os.close( fd)

print "Closed the file successfully!!"

When the above code is executed, it will produce the following result -


Maximum number of links to the file. :127
Maximum length of a filename :255
Closed the file successfully!!

Alright guys! This is where we are rounding up for this tutorial post. In our next tutorial, we are going to be studying about the Python OS fstat() Method.
