pid is supported. wait() will just return -1 and set errno to
ECHILD.

Bananymous 88e92eec9e LibC: Add simple definition for realloc

Bananymous faf14b880e LibC: Rewrite all the headers. 
We now have more or less posix issue 2018 conforming libc headers.

This was a really time consuming and boring operation but it had to
be done.

Now we get to actually start implementing libc :)

Bananymous 49fe3d0d4f LibC: add probably functional *printf 
I wrote a general printf function that takes an putc function
pointer. We can use this to implement all the printf family
functions. I haven't done thorough testing with this, but it seems
to be functional for the most part

Bananymous 3f9d6f0311 LibC: add needed stubs to build executables with our compiler 2023-04-12 17:53:02 +03:00
Bananymous aa2aee684b Kernel: remove message from BAN::Error 
We don't store the error message anymore in BAN::Error.
Instead we store a error code that can be mapped into a string.
This allows BAN::Error to only take 4 bytes instead of 128.

We should also make some kernel initialization just panic instead
of returning errors since they are required for succesfull boot
anyway.
