Giving C a superpower: custom header file (safe_c.h)

Nice, but if the intention is portability my experience has unfortunately been that you pretty much have to stick to C99. MSVC’s C compiler is rough, but pretty much necessary for actual cross platform. I have my own such header which has many, many things like the OP’s. As much as I would find it constantly useful, I don’t have a cleanup utility because of this.

But if you can stay out of MSVC world, awesome! You can do so much with a few preprocessor blocks in a header

MSVC now supports C17.

MSVC is also made out of a dozen javascript processes which makes typing text need a beefy computer.

MSVC is a C++ compiler toolchain and it does not contain any JavaScript. You're thinking of VSCode, probably, but your comment was an off-topic rant either way.

Microsoft visual studio the IDE (not vs code the electron program) has lots of javascript processes running in the background doing all sorts of things.

Also my comment was a single sentence with a single fact so it can't be a rant.

MSVC is also completely different from Visual Studo. It’s OK to say you were wrong. You don’t have to be angry online. I promise!
