CLIL source code from book "Firmware demystified"

Hello, All!

Recently this book has fallen into my hands and I was reviewing the chapter
dedicated to development of Command Line Interface for generic embedded
system.

I was confused, the author offers unusual method: there is main function
getting command line from user and parsing it, than calls appropriate
function (for example, which shows env. variables: show_env()) and pass
'argc' and 'argv[]' to that function (assuming that in CLI prompt you enter
some arguments, like 'show env current').

How is it possible to work?

With best regards, Roman Mashak. E-mail: mrv@xxxxxxxx
