Structure used for scatter\/gather data output when sending multiple
messages or packets in one go. You generally pass in an array of
@/GOutputVectors/@ and the operation will use all the buffers as if they
were one buffer.

If /@address@/ is 'Nothing' then the message is sent to the default receiver
(as previously set by 'GI.Gio.Objects.Socket.socketConnect').
