Code formatting

[Rubo3]

Have you thought about using a code formatter like astyle or uncrustify? It's good to have a consistent style.

That you be great, I like to follow the same formatting rules.

Great! I was playing with astyle, it's dead easy to use, I ran:

astyle --style=google --attach-closing-while --indent-preproc-block --indent-preproc-define --indent-col1-comments --pad-oper --pad-comma --pad-header --unpad-paren --align-reference=name --break-one-line-headers --remove-braces --break-return-type --break-return-type-decl --convert-tabs --remove-comment-prefix --max-code-length=100 --break-after-logical < vkvg_context.c > vkvg_context_beautified.c

and this is the result: vkvg_context_beautified.txt.
Not bad, but it could be better. On the other hand, uncrustify has many more options, but the documentation is very minimal.
You can take some time to try some configurations and then decide which one you like more.
