/// The parameter should be a call to a systemd FFI fn with an c_int return
/// value. It is called, and if the return is negative then `sd_try!()`
/// interprets it as an error code and returns IoError from the enclosing fn.
/// Otherwise, the value of `sd_try!()` is the non-negative value returned by
/// the FFI call.
