# Lanskern

Lanskern is a minimal kernel written in C. It's a hobby project. Currently it's in very early development. More features will be added in the future. The kernel comes with a fork of ManuOS.

## Requirements

- gcc

- make

- NASM

- Linux based OS

- QEMU

- grub

## How to build

1. Type `make` in the terminal. This builds the kernel to an `Lanskern.iso` file and launches it in QEMU.

## System calls

- `syswrite32(char *buf, int len)`: Write a string to the screen

- `sysread32(char *buf, int len, int echo)`: Read a string from the screen

- `sysreade32(char *buf, int len, int echo)`: Read a string from the screen until enter is pressed

- `sysrestart32()`: Restart the kernel
