# Rust isatty
[](https://travis-ci.org/dtolnay/isatty)
[](https://crates.io/crates/isatty)
This crate provides the following two functions:
```rust
fn stdout_isatty() -> bool
fn stderr_isatty() -> bool
```
On Linux and Mac they are implemented with
[`libc::isatty`](http://man7.org/linux/man-pages/man3/isatty.3.html).
On Windows they are implemented with
[`kernel32::GetConsoleMode`](https://msdn.microsoft.com/en-us/library/windows/desktop/ms683167.aspx).
## Usage
`Cargo.toml`
> ```toml
> [dependencies]
> isatty = "0.1"

`src/main.rs`
> ```rust
> extern crate isatty;
> use isatty::{stdout_isatty, stderr_isatty};
