Explore how the fork function creates parent and child processes by replicating code execution in C under Linux. Understand the return values of fork and getppid, and see practical applications such as performing simultaneous tasks. This lesson guides you through managing process IDs and using fork to run parallel activities in C programs on Linux systems.

We have already learned, in the last lesson, that fork() replicates the code of the parent process in the child process. The code inside fork() is executed only once. Whereas, the rest of the code is executed twice. Therefore, there will be two return calls from the fork() function, ...
