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. Acked-by: Frediano Ziglio <fziglio@redhat.com>
