Usage

File: Cargo.toml

```toml ...

[dependencies] kernel32-sys = "*" win32-error = "0.9.0" ```

File: main.rs ```rust extern crate kernel32; extern crate win32_error;

use win32_error::*; use kernel32::OpenProcess; // needs to be brought so description function can be used use std::error::Error;

fn main() { func(); }

fn func() { let processterminate = 0x0001; let h = unsafe { OpenProcess(processterminate, 0, 4) }; let err = Win32Error::new(); println!("{}", err); // => 5: Access is denied (or localized):

let err = Win32Error::from(6); // => 6: Handle is invalid (or localized):
println!("{}", err);

println!("{}", err.description()); // => Handle is invalid (or localized)
println!("Error code is {}", err.get_error_code()); // => Error code is 6

// pass some crazy error
let err = Win32Error::from(885848);
println!("{}", err); // => 885848: Unknown error

}

// From 0.8.0 and above fn getresultok() -> Win32Result { Err(Win32Error::new()) } ```
