Rust bindings to getzoneid(3C), getzoneidbyname(3C), and getzonenamebyid(3C) for illumos based systems.
``` rust extern crate zonename;
fn main() { // Max zonename length let zonenamemax = zonename::ZONENAMEMAX; println!("zonenamemax = {}", zonenamemax);
// Get the current zone id
let zoneid = zonename::getzoneid().expect("failed to get zoneid");
println!("getzoneid() = {}", zoneid);
// Get the zonename for the current zone id (our zonename)
let zonename = zonename::getzonenamebyid(zoneid).expect("failed to get zonename");
println!("getzoneidbyname({}) = {}", zoneid, zonename);
// Convenience wrapper for getting our current zonename
let zonename = zonename::getzonename().expect("failed to get zonename");
println!("getzonename() = {}", zonename);
// Try to get a fake zoneid
let zoneid = -1;
match zonename::getzonenamebyid(zoneid) {
Ok(name) => println!("getzonenamebyid({}) = name: {}", zoneid, name),
Err(err) => println!("getzonenamebyid({}) = err: {}", zoneid, err)
};
// Try to get a fake zonename
let zonename = "fake zone";
match zonename::getzoneidbyname(zonename) {
Ok(num) => println!("getzoneidbyname('{}') = num: {}", zonename, num),
Err(err) => println!("getzoneidbyname('{}') = err: {}", zonename, err)
};
} ```
