# Function std::fs::read_link [−] [src]

    pub fn read_link<P: AsRef<Path>>(path: P) -> Result<PathBuf>

Reads a symbolic link, returning the file that the link points to.

# Platform-specific behavior

This function currently corresponds to the `readlink` function on Unix and the `CreateFile` function with `FILE_FLAG_OPEN_REPARSE_POINT` and `FILE_FLAG_BACKUP_SEMANTICS` flags on Windows. Note that, this may change in the future.

# Errors

This function will return an error in the following situations, but is not limited to just these cases:

- `path` is not a symbolic link.
- `path` does not exist.

# Examples

fn main() { use std::fs; fn foo() -> std::io::Result<()> { let path = try!(fs::read_link("a.txt")); Ok(()) } }

    use std::fs;

    let path = try!(fs::read_link("a.txt"));

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize`)
