# Example

Here is a program that sleeps until it receives three `SIGINT` signals.

```rust

extern crate signalbool;

extern crate nix;

use nix::unistd::sleep;

fn main() {

  let mut sb = signalbool::SignalBool::new(

    &[signalbool::Signal::SIGINT], signalbool::Flag::Interrupt,

  ).unwrap();

  let mut count = 0;

    

  loop {

    sleep(10);

    if sb.caught() {

      println!("Caught SIGINT.");

      count += 1;

      sb.reset();

      if count == 3 {

        break;

      }

    }

  }

}

```
