def handle_error(errcode):
    """Error handler function. Translates an error code into an exception."""
    if type(errcode) is c_int:
        errcode = errcode.value
    if errcode == 0:
        pass  # no error
    elif errcode == -1:
        raise TimeoutError("the operation failed due to a timeout.")
    elif errcode == -2:
        raise LostError("the stream has been lost.")
    elif errcode == -3:
        raise InvalidArgumentError("an argument was incorrectly specified.")
    elif errcode == -4:
        raise InternalError("an internal error has occurred.")
    elif errcode < 0: 
        raise RuntimeError("an unknown error has occurred.")
