Chapter 1 Messages

Within a TIBCO SmartSockets application, interprocess communication occurs through messages. A message is a packet of information sent from one process to one or more other processes providing instructions or data for the receiving process. Messages can carry many different kinds of information, including:

variable data in the form of a series of variable names and their values, the most common use of a message

commands to a process’s command interface

user-defined binary data, such as images or multi-byte strings

monitoring information about RTserver and RTclient processes

guaranteed message delivery (GMD) information about other messages

This chapter describes message composition, message types, how to create message types, and how to work with messages. Also discussed are message files that are used during the development phase for testing and debugging purposes.
