A simple crate to catch signals and set a boolean flag for later use.

This crate doesn't create threads behind the scene.

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; } } } } ```
