No, for a good modern C alternative I’d look at Zig. The main reason C is used for the Linux kernel is because Linus hates C++ for a variety of reasons. For what it’s worth I agree with him. Most other OS kernels are written in C++. Linus allowed Rust in because it demonstrated that it could provide the same power as C++ without all of C++'s problems (mostly that over the years it became a kitchen sink language, anything that anyone ever thought might be a good idea got rolled in even when it was incompatible with some other feature already in the language).
Thanks for the suggestion. How does Zig compare to C safety wise? One of my main reasons for going for Rust was because I was looking for something like C but safer
It’s a bit safer and a lot more convenient to use, but still lets you do dangerous things with pointers. At its core it’s still fundamentally the same as C just with a bunch of helpful tools and features to make doing all the stuff you do in C easier and more convenient.
Really the biggest thing it does significantly better than C is its macro system. C macros are “dumb” in that the C pre-processor does a simple find and replace on the source files without doing any kind of processing on the underlying C code so you can E.G. write C macros that spit out mangled illegal C code when you run them. Likewise a C #include is literally the same thing as copy and pasting the contents of the included file before it gets fed into the compiler.
Zig on the other hand has a smart macro system that’s actually aware of the zig code and works in concert with it at compile time.
Interesting. I always assumed that Rust would be more similar to C since they are now using Rust in the linux kernel

Okay that makes sense. Thanks for the comparisons here
