//! System calls for getting the terminal size.
//!
//! Getting the terminal size is performed using an ioctl command that takes
//! the file handle to the terminal -- which in this case, is stdout -- and
//! populates a structure containing the values.
//!
//! The size is needed when the user wants the output formatted into columns:
//! the default grid view, or the hybrid grid-details view.
//!
//! # Example
//!
//! To get the dimensions of your terminal window, simply use the following:
//!
//! ```no_run
//! # use term_size;
//! if let Some((w, h)) = term_size::dimensions() {
//!     println!("Width: {}\nHeight: {}", w, h);
//! } else {
//!     println!("Unable to get term size :(")
//! }
//! ```
