Function lgetxattr 

pub fn lgetxattr<P: Arg, Name: Arg, Buf: Buffer<u8>>(
    path: P,
    name: Name,
    value: Buf,
) -> Result<Buf::Output>

lgetxattr(path, name, value.as_ptr(), value.len())—Get extended filesystem attributes, without following symlinks in the last path component.

Unlike the libc lgetxattr function, this function does not treat an buffer with zero length as a way to return the size of the attribute. To obtain the size, use lgetxattr_query.
