This crate provides some wrappers aground common used WinApi functions. 
The purpose of this library is originally meant for [crossterm](https://github.com/TimonPost/crossterm), but could be used apart from it.
Although, notice that it unstable right because some changes to the API could be expected.

# Features
This crate provides some abstractions over reading input, console screen buffer, and handle.

_The following WinApi calls_
- CONSOLE_SCREEN_BUFFER_INFO (used to extract information like cursor pos, terminal size etc.)
- HANDLE (the handle needed to run functions from WinApi)
- SetConsoleActiveScreenBuffer (activate an other screen buffer)
- Set/GetConsoleMode (e.g. console modes like disabling output)
- SetConsoleTextAttribute (eg. coloring)
- SetConsoleWindowInfo (changing the buffer location e.g. scrolling)
- FillConsoleOutputAttribute, FillConsoleOutputCharacter (used to replace some block of cells with a color or character.)
- SetConsoleInfo
- ReadConsoleW

# Example 
The [examples](./examples) folder has more complete and verbose examples.

## Screenbuffer information
```rust 
use crossterm_winapi::{ScreenBuffer, Handle};

fn print_screen_buffer_information() {
    let screen_buffer = ScreenBuffer::current().unwrap();

    // get console screen buffer information
    let csbi = screen_buffer.info().unwrap();

    println!("cursor post: {:?}", csbi.cursor_pos());
    println!("attributes: {:?}", csbi.attributes());
    println!("terminal window dimentions {:?}", csbi.terminal_window());
    println!("terminal size {:?}", csbi.terminal_size());
}
```
## Handle 
```rust
use crossterm_winapi::{HandleType, Handle};

fn get_different_handle_types() {
    let out_put_handle = Handle::new(HandleType::OutputHandle).unwrap();
    let out_put_handle = Handle::new(HandleType::InputHandle).unwrap();
    let curr_out_put_handle = Handle::new(HandleType::CurrentOutputHandle).unwrap();
    let curr_out_put_handle = Handle::new(HandleType::CurrentInputHandle).unwrap();
}
```
