Show HN: I rewrote few of the common core string.h functions
github.com/deep-vinciI rewrote the most common core string.h functions in pure C. I mostly did it to learn pointers and string. Would love to get any feedbacks:)

Depending on what exactly you are trying to learn from this, I would recommend looking at the source for musl like https://git.musl-libc.org/cgit/musl/tree/src/string and trying to understand why it looks so much more complicated than the simple implementation.
Look at glibc. eg: https://github.com/lattera/glibc/blob/master/string/strcpy.c
how do you know that the implementation is correct? i don't see tests
`r_strlen` truncates the output length on 64bit systems (size_t is 64 bits while int is 32 bits).
You should be compiling with -Wall -Werror.
If you specifically want code review, consider submitting the code to the code review SE https://codereview.stackexchange.com/
I would rather see some novel, simple, easy to use c string library.
I dunno about novel, I have used (some of) these functions extensively: https://github.com/lelanthran/libds/blob/master/src/ds_str.h
what does easy means here? can you elaborate?
strcmp doesn’t return a bool.
Is this meant to be used in production systems, or is it just a learning exercise?
