> 
> The only time that the pipe item needs to be passed as the third
> argument to red_channel_client_init_send_data() is when the pipe item
> holds a data buffer that has been added to the marshaller by reference
> (spice_marshaller_add_by_ref()) and needs to be kept alive until the
> data has been sent. In all other cases, the item does not need to be
> kept alive, so we can safely pass NULL for this third parameter.
