Conclusion

Forking

Learn about the functionality of fork( ) in this lesson.

We'll cover the following

- - fork()
  - Example program
- - Explanation

We have already learned, in the last lesson, that a running program is known as a process, and we can create another process from this running program. The first one is known as the parent process; whereas, the second one is known as the child process.

`fork()`

fork() launches a child process. Control goes to fork() only once. Whereas, control returns from fork() twice.

Example program

See the code given below:
