# errno-no-std
Cross-platform interface to the `errno` variable.
An improved version of the [`errno`](https://crates.io/crates/errno) crate.
## Examples
```rust
use errno::{Errno, errno, set_errno};
// Get the current value of errno
let e = errno();
// Set the current value of errno
set_errno(e);
// Extract the error code as an i32
let code = e.0;
// Display a human-friendly error message
println!("Error {}: {}", code, e);
```
