Receiving Messages

This chapter describes how to retrieve messages delivered to your application and how to handle the message once you have examined it. It also shows you how to send replies to requests that you receive.

To retrieve and handle ToolTalk messages, your application must perform several operations: it must be able to retrieve ToolTalk messages; it must be able to examine messages; it must provide callback routines; it must be able to respond to requests; and it must be able to destroy the message when it is no longer needed.
