Andreas Kling 5af4e622b9 Kernel: Add KResult and KResultOr<T> classes.
The idea here is to combine a potential syscall error code with an arbitrary
type in the case of success. I feel like this will end up much less error
prone than returning some arbitrary type that kinda sorta has bool semantics
(but sometimes not really) and passing the error through an out-param.

This patch only converts a few syscalls to using it. More to come.

Serenity

x86 Unix-like operating system for IBM PC-compatibles.

About

I always wanted to write my own operating system, but I never took it seriously. Until now.

Current features

  • Pre-emptive multitasking
  • Compositing window server (in userspace)
  • ext2 filesystem support
  • mmap()
  • Unix-like libc and userland
  • Pseudoterminals
  • Event-driven GUI library
  • Other stuff I can't think of right now...

How do I get it to run?

You need a cross-compiler for the i686-elf target. I've only tested this on an Ubuntu 18.10 host with GCC, so I'm not sure it works anywhere else.

If you'd like to run it, here's how you'd get it to boot:

cd Kernel
./makeall.sh
./run q          # Runs in QEMU
./run            # Runs in bochs
