OS module in Python provides functions for interacting with the operating system. OS comes under Python’s standard utility modules. This module provides a portable way of using operating system dependent functionality.
os.get_inheritable() method in Python is used to get the value of inheritable flag of the specified file descriptor.
Inheritable flag of a file descriptor tells that if it can be inherited by the child processes or not. For example: if the parent process has a file descriptor 4 in use for a particular file and parent creates a child process then the child process will also have file descriptor 4 in use for that same file, if the inheritable flag of the file descriptor 4 in the parent process is set.
Syntax: os.get_inheritable(fd)
Parameter:
fd: A file descriptor whose inheritable flag is to be checked.Return Type: This method returns a Boolean value of class bool which represents the value of inheritable flag of the specified file descriptor.
# Python program to explain os.get_inheritable() method # importing os module import os # File path path = "/home/ihritik/Desktop/file.txt" # Open the file and get # the file descriptor associated # with it using os.open() method fd = os.open(path, os.O_RDWR | os.O_CREAT) # Get the value of # inheritable flag of the # file descriptor fd using # os.get_inheritable() method inheritable = os.get_inheritable(fd) # print the value of inheritable flag print("Value of inheritable flag:", inheritable) # Value of inheritable flag can be set / unset # using os.set_inheritable() method # For example: # change inheritable flag os.set_inheritable(fd, True) # Print the value of inheritable flag inheritable = os.get_inheritable(fd) print("Value of inheritable flag:", inheritable) |
Value of inheritable flag: False Value of inheritable flag: True
