| * @include: gio/gio.h |
| * @see_also: #GSocketConnection. |
| * |
| * A #GTcpWrapperConnection can be used to wrap a #GIOStream that is |
| * based on a #GSocket, but which is not actually a |
| * #GSocketConnection. This is used by #GSocketClient so that it can |
| * always return a #GSocketConnection, even when the connection it has |
| * actually created is not directly a #GSocketConnection. |

| * Since: 2.28 |
