single-instance 0.1.0

A rust library for single instance application.

single-instance provides a single API to check if there are any other running instance.

Usage

On Windows, init SingleInstance will create a Mutex named by given &str then check error code by calling GetLastError. On Linux, init will create or open a file which path is given &str, then call flock to apply an advisory lock on the open file.

Examples

extern crate single_instance;

use std::thread;
use single_instance::SingleInstance;

fn main() {
    let instance = SingleInstance::new("whatever").unwrap();
    let is_single = instance.is_single();
    assert!(is_single);
}
