#### Description [src]

    struct GOutputMessage {
      GSocketAddress* address;
      GOutputVector* vectors;
      guint num_vectors;
      guint bytes_sent;
      GSocketControlMessage* control_messages[];
      guint num_control_messages;
    }

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 `NULL` then the message is sent to the default receiver (as previously set by g_socket_connect()).

###### Structure members

`address:` `GSocketAddress`

  A `GSocketAddress`, or `NULL`.

`vectors:` `GOutputVector`

  Pointer to an array of output vectors.

`num_vectors:` `guint`

  The number of output vectors pointed to by `vectors`.

`bytes_sent:` `guint`

  Initialize to 0. Will be set to the number of bytes that have been sent.

`control_messages:` `GSocketControlMessage`

  A pointer to an array of `GSocketControlMessages`, or `NULL`.

`num_control_messages:` `guint`

  Number of elements in `control_messages`.
