Function librelic::prelude::sys::readlink

pub fn readlink<T>(path: T) -> Result<PathBuf, FuError> where
    T: AsRef<Path>, 

Returns the absolute path for the given link target. Handles path expansion

Examples

use fungus::prelude::*;

let tmpdir = PathBuf::from("tests/temp").abs().unwrap().mash("path_doc_readlink");
assert!(sys::remove_all(&tmpdir).is_ok());
let file1 = tmpdir.mash("file1");
let link1 = tmpdir.mash("link1");
assert!(sys::mkdir(&tmpdir).is_ok());
assert!(sys::touch(&file1).is_ok());
assert!(sys::symlink(&link1, &file1).is_ok());
assert_eq!(sys::readlink(link1).unwrap(), file1);
assert!(sys::remove_all(&tmpdir).is_ok());
