Creating child process using fork() in Python
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 –
System Call Used :fork() : fork() is an operation whereby a process creates a copy of itself. It is usually a system call, implemented in the kernel.getpid() : getpid() returns the process ID (PID) of the calling process.
Below is Python program implementing above :
"Parent process and id is : "
"Child process and id is : "
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.
