Fork handlers may be established by means of the pthread_atfork() function in order to maintain application invariants across fork() calls. When the application calls fork() from a signal handler and any of the fork handlers registered by pthread_atfork() calls a function that is not async-signal-safe, the behavior is undefined.
The use of fork and exec exemplifies the spirit of UNIX in that it provides a very simple way to start new tasks. Note the use of the word task here, I have deliberately avoided using the terms process or program, which you can define as: a process is an "engine of execution", something within the operating system which is capable of running a program; and a program is a specific piece of code ...

In many programs and man pages of Linux, I have seen code using fork(). Why do we need to use fork() and what is its purpose?

When you enter fork, there's only a single process. While inside fork, this single process is cloned/copied. Now there are two processes running the same code in parallel. Both processes are still inside the fork function. Eventually, each process will exit the fork function: the parent process will exit the fork function (returning the PID of the child) and the child process will exit the ...
