fork(2) is used to create all new processes on a unix system, each new process is created by having a parent process "fork" a child process. fork(2) is essential to many programs and features an API which could lend itself to confusion.

Write an EXAMPLES section for the fork(2) manpage(s) showing the usage of the functions defined in those manpage(s) in a plausible, real-world and if possible only semi-contrived scenario.

All examples should follow the style guidelines in the style(9) manpage.

All examples should be written in a manner that is self-documenting and make copious use of comments in order to explain the actions being taken.

Examples should be real and working code. They should not include headers or even a main function, but it should be reasonable for a developer to copy and paste an example from a manpage and expect it to work.

An example of a manpage with excellent example code is umtx(2).

Deliverables: A complete EXAMPLES manpage section in mdoc format.
