Writing subscriber applications

 

Subscriber applications communicate with the broker using command messages in the RF Header format (or the equivalent functions in the Application Messaging Interface). Subscribers need to register with a broker before they can start receiving publications. They can also request certain types of publication from the broker or directly from the publisher.

This chapter discusses the following topics:

• Registering as a subscriber

• Requesting information

• Deregistering as a subscriber

We can see an example of a subscriber application in Sample programs.
