Welcome to our deep dive into the Fork System Call! 🖥️

In this video, we unravel the complexities of the fork() system call, an essential concept in Unix-like operating systems. You'll learn how fork() is used to create new processes, the parent-child process relationship, and how it plays a crucial role in process management.

What You'll Learn:
What is Fork?: An introduction to the fork() system call and its significance.
How Fork Works: Step-by-step explanation of how fork() creates a new process.
Parent and Child Processes: Understanding the dynamics between parent and child processes.
Practical Examples: Real-world coding examples demonstrating the usage of fork() in C programming.
Common Pitfalls: Tips to avoid common mistakes and best practices.
Whether you're a beginner or looking to brush up on your knowledge, this video will give you a clear and comprehensive understanding of the fork() system call.

#Chapter1
#ForkSystemCall
#fork()
The fork system call is used to create a new processes. The newly created process is the child process. The process which calls fork and creates a new process is the parent process. The child and parent processes are executed concurrently.
But the child and parent processes reside on different memory spaces. These memory spaces have same content and whatever operation is performed by one process will not affect the other process.
When the child processes is created; now both the processes will have the same Program Counter (PC), so both of these processes will point to the same next instruction. The files opened by the parent process will be the same for child process.
When the child process is successfully created, the PID of the child process is returned in the parent process and 0 will be returned to the child process itself.
If there is any error then -1 is returned to the parent process and the child process is not created.
