standard UNIX fork() return child's pit to the parent and returns 0 to the child. Instead, imagine that fork() returns 0 to the parent and returns parent's pid to the child. What would be a potential issue with this semantic?
According to the general fork() function. The purpose of fork() is to create a new process, in which becomes the child process of the parent. It returns a process ID.
Below are different values returned by fork().
But the given scenario is distinct.Normally the fork() returns 0 to the parent and in turn child PID from the parent.
Here assuming fork() returns 0 to parent and returns parent's PID to the child means the function fork() is recursively applying on a single process and no child is being created.
For a unique process the same fork() function is calling again and again.If a child got created means compulsorily it will act as dual under same address space and returns child PID to parent process.

This is for a Unix class. Please help me out. I am attaching a skeletal code of the program below, it just needs ti be filled in. Below is a skeletal code of the program.
