set_cwd

fn set_cwd(string path) -> Result<unit, EnvError>

use env::{set_cwd};

Changes the current working directory of the whole process.

Relative paths opened later, and programs started with exec, use the new directory. Returns Err(EnvError::Other) if path does not exist or is not an accessible directory. Needs --allow-env.

let _ = set_cwd(before);
