HelloWorld
==========

Description
***********

The basic ddscxx HelloWorld example is used to illustrate the necessary steps to setup DCPS entities.

Design
******

It consists of 2 units:

- ddscxxHelloworldPublisher: implements the publisher's main
- ddscxxHelloworldSubscriber: implements the subscriber's main

Scenario
********

The publisher sends a single HelloWorld sample. The sample contains two fields:

- a userID field (long type)
- a message field (string type)

When it receives the sample, the subscriber displays the userID and the message field.

Running the example
*******************

It is recommended that you run the subscriber and publisher in separate terminals to avoid mixing the output.

- Open 2 terminals.
- In the first terminal start the subscriber by running ddscxxHelloworldSubscriber
- In the second terminal start the publisher by running ddscxxHelloworldPublisher
