Function fork::chdir

pub fn chdir() -> Result<c_int, i32>

Change dir to / see chdir(2)

Upon successful completion, 0 shall be returned. Otherwise, -1 shall be returned, the current working directory shall remain unchanged, and errno shall be set to indicate the error.

Example:

use fork::chdir;
use std::env;

fn main() {
    match chdir() {
        Ok(_) => {
           let path = env::current_dir().expect("failed current_dir");
           assert_eq!(Some("/"), path.to_str());
        }
        _ => panic!(),
    }
}
