import os, sys

# Faylni oching

fd = os.open ("foo.txt", os.O_RDWR | os.O_CREAT)

bosib chiqarish ("% s"% os.pathconf_names)

# Endi faylga maksimal havolalarni oling.

no = os.fpathconf (fd, 'PC_LINK_MAX')

bosib chiqarish ("faylga havolalarning maksimal soni.% d"% no)

# Endi fayl nomining maksimal uzunligini oling

no = os.fpathconf (fd, 'PC_NAME_MAX')

bosib chiqarish ("Fayl nomining maksimal uzunligi:% d"% no)

# Ochilgan faylni yopish

os.close (fd)
