Python | os.set_inheritable() method
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.set_inheritable() method in Python is used to set 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.set_inheritable(fd, inheritable)
Parameter:
fd: A file descriptor whose inheritable flag is to be set.
inheritable: An integer or a Boolean value representing the new value of inheritable flag.Return Type: This method does not return any value.

Current value of inheritable flag: False Inheritable flag modified Current value of inheritable flag: True
