Basic concurrency with fork()

Wed, 23 Jun 2021 00:00:00 +0000

When programming on Linux/Unix, the function fork(2) allows us to create new processes. This is a short and example-driven introduction to the basics of using that function.

First stab

After a brief look at the manual page for fork(2) we can tell that it returns a value of type pid_t and does not take any arguments:

NAME
     fork – create a new process

SYNOPSIS
     #include <unistd.h>

     pid_t
     fork(void);

Let us simply call fork and see what happens and what values does it return.
