Create a child process and display process id of both parent and child process.
Fork system call use for creates a new process, which is called child process, which runs concurrently with process (which process called system call fork) and this process is called parent process. After a new child process created, both processes will execute the next instruction following the fork() system call.
Library used :
os : The OS module in Python provides a way of using operating system dependent functionality. The functions that the OS module provides allows you to interface with the underlying operating system that Python is running on; be that Windows, Mac or Linux. It can be imported as –
import os
System Call Used :
Below is Python program implementing above :
# Python code to create child process import os def parent_child(): n = os.fork() # n greater than 0 means parent process if n > 0: print("Parent process and id is : ", os.getpid()) # n equals to 0 means child process else: print("Child process and id is : ", os.getpid()) # Driver code parent_child() |
Output :
Child process and id is : 32523 Parent process and id is : 32524
Note : Output can vary time to time, machine to machine or process to process.
