Functions:
-> When function returns pointer, asterisk character must be aligned to return type (char*), example for "ok" and "wrong" is the same.

I tried using the astyle-code-format.cfg file with style but it almost only fixes indents and braces. I like the rules you described for variable and function naming but I couldn't find a way to format my C files according to that. There is no such option in AStyle. So even if I use your cfg file with AStyle, there is no difference between using yours or a predefined XML file on Eclipse (like original K&R etc.)

Many IDE and editors use clang-format to format code, like VSCode, Clion, Visual Studio, QtCreator.

BasedOnStyle: GNU may help

Hey! I think this is a great style guide and as I'm reading through it I'm going "yep, yep, yep" as I agree with nearly all of it. I intend to adopt a few of these too like the prv_ idea. A few things though:

• What is wrong with first curly bracket on the next line?

• Not initialising variables to 0? In places I've worked, uninitialised variables will fail your peer review.

• Declaring all variables at the top of a block is a bit old fashioned.

• I think it's nicer to underscore de-limit function names and camel-case variables. void my_func(void); int32_t myVar = 0;

• I agree strongly with documenting #if/#elif/#else/#endif statements. Oh my god this helps so much!

Problem Description

This project has no LICENSE file at its root.

Technically I believe this makes it your intellectual property, and others that find it shouldn't assume you're willing to share it... I'm no lawyer, but if this were a software project, it wouldn't be OSS without a license.

Assumption : Intended to be open (?)

I'm assuming you're happy for people to share and use this for their own projects openly... either way, if your intent for this standard is:

• open: an open license is necessary for people to use it legally
• closed: a license stating that you'd like to be contacted before it's copied would also be helpful to those that find it.
