```c
#include <logging.h>
#include <module.h>

static int init(void) {
    debug_print(NOTICE, "hello world");
    return 0;
}

static int fini(void) {
    return 0;
}

MODULE_DEF(hello, init, fini);
```

--------------------------------

### Run ToaruOS in QEMU

Source: https://github.com/klange/toaruos/blob/master/README.md

Recommended QEMU command line for ToaruOS development. Replace KVM acceleration options based on your host platform. Note that QEMU options may change between versions.

```bash
qemu-system-x86_64 -enable-kvm -m 1G -device AC97 -cdrom image.iso -smp 2
```

--------------------------------

### Boot ToaruOS with Grub

Source: https://github.com/klange/toaruos/blob/master/README.md

Commands to boot ToaruOS using Grub, supporting Multiboot and Multiboot 2 specifications. Ensure correct paths to the kernel and ramdisk are provided.

multiboot2 /path/to/misaka-kernel root=/dev/ram0 migrate vid=auto start=live-session
module2 /path/to/ramdisk.igz
set gfxpayload=keep
```

--------------------------------

### Build ToaruOS with Docker

Source: https://github.com/klange/toaruos/blob/master/README.md

Use this command to build ToaruOS from source within a Docker container. Ensure the ToaruOS repository is mounted at /root/misaka. This process requires cloning the repository and initializing submodules.

```bash
git clone https://github.com/klange/toaruos
cd toaruos
git submodule update --init kuroko
git submodule update --init bim
docker pull toaruos/build-tools:1.99.x
docker run -v `pwd`:/root/misaka -w /root/misaka -e LANG=C.UTF-8 -t toaruos/build-tools:1.99.x util/build-in-docker.sh
```

--------------------------------

### Build ToaruOS Docker Image

Source: https://github.com/klange/toaruos/blob/master/util/docker/README.md

Build the base Docker image for ToaruOS development from the Dockerfile.

```bash
docker build .
```

--------------------------------

### Activate ToaruOS Toolchain

Source: https://github.com/klange/toaruos/wiki/How-to-Python

Source this script to add the ToaruOS cross-compilation toolchain to your PATH.

```bash
source util/activate.sh
```

### Extend the Debug Shell with a New Command

Source: https://github.com/klange/toaruos/wiki/Modules

This module adds a new command, 'hello', to the debug shell. It uses macros from `<mod/shell.h>` to define and bind the shell function. The module depends on the 'debugshell' module.

```c
#include <module.h>
#include <mod/shell.h>

DEFINE_SHELL_FUNCTION(hello, "Print 'hello world'") {
    fs_printf(tty, "hello world\n");
    return 0;
}

static int init(void) {
    BIND_SHELL_FUNCTION(hello);
    return 0;
}

static int fini(void) {
    return 0;
}

MODULE_DEF(hello, init, fini);
MODULE_DEPENDS(debugshell);
```

--------------------------------

### Send Screenshot from ToaruOS VM

Source: https://github.com/klange/toaruos/wiki/Screenshots

Use this command within the ToaruOS VM to send the captured screenshot file over the network to the listening host. This requires netcat to be available in the VM.

```bash
cat /tmp/screenshot.tga > /dev/net/10.0.2.1:9999
```

--------------------------------

### Old VFS Virtual Function Types (C)

Source: https://github.com/klange/toaruos/wiki/New-VFS

Defines the type aliases for various virtual functions used in the previous VFS implementation. These cover read, write, open, close, readdir, finddir, create, unlink, mkdir, ioctl, get_size, and chmod operations.

```c
typedef uint32_t (*read_type_t) (struct fs_node *, uint32_t, uint32_t, uint8_t *);
typedef uint32_t (*write_type_t) (struct fs_node *, uint32_t, uint32_t, uint8_t *);
typedef void (*open_type_t) (struct fs_node *, unsigned int flags);
typedef void (*close_type_t) (struct fs_node *);
typedef struct dirent *(*readdir_type_t) (struct fs_node *, uint32_t);
typedef struct fs_node *(*finddir_type_t) (struct fs_node *, char *name);
typedef void (*create_type_t) (struct fs_node *, char *name, uint16_t permission);
typedef void (*unlink_type_t) (struct fs_node *, char *name);
typedef void (*mkdir_type_t) (struct fs_node *, char *name, uint16_t permission);
typedef int (*ioctl_type_t) (struct fs_node *, int request, void * argp);
typedef int (*get_size_type_t) (struct fs_node *);
typedef int (*chmod_type_t) (struct fs_node *, int mode);
```
