-//! Cross-platform interface to the `errno` variable.

-//! # Examples
-//! ```
-//! 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);
