Bananymous cae0a1cc60 LibC: add working f modifier to printf 
This is implementation will write out of bounds if the conversion
takes more than 1024 characters (either super large number or very
big percision).

Also we dont handle NaN and infinity cases

Bananymous 480d92fce5 LibC: add better error string support 2023-05-10 02:22:31 +03:00
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 ff2e2937a5 Kernel: Remove offset from OpenFileDescriptor 
This is now handled on the libc side. There might be reasons to
have it in kernel side, but for simplicity's sake I'm moving it
to libc for now :)

Bananymous 12e42f40c5 Kernel/LibC: add free function for FixedWidthAllocator 
I have to rework the syscall API and allocators in process. For
now this works well enough :)

Bananymous bcfd838131 Kernel: Add basic fixed width allocator for userspace 
We have to move process stacks to the general heap and maybe map
kernel to higher half.

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.

Bananymous 781cc78a1f BuildSystem: Fix header copying to sysroot 
We used to copy all headers everytime to sysroot which caused
rebuild of the whole os. Now we use the cmake command
'copy_directory_if_different' which seemed to fix this issue :)

Bananymous 25ddc24754 BuildSystem: cmake can now build out libc

Bananymous 4c5176f751 BuildSystem: We are now using cmake instead of plain make 
I have been annoyed for a while since I had to build everything
when running the os since the buildsystem was really bad.

I wanted to rewrite the whole build system and changed to using cmake

:)
