This chapter provides instructions on how to participate in
a ToolTalk session. It also shows you how to manage the storage
of values passed in from the ToolTalk service and how to handle
errors that the ToolTalk service returns.
To use the ToolTalk service, your application calls ToolTalk
functions from the ToolTalk application programming interface (API)
library. To modify your application to use the ToolTalk service,
you must first include the ToolTalk API header file in your program.
After you have initialized the ToolTalk service and joined a session,
you can join files and additional user sessions. When your process
is ready to quit, you unregister your message patterns and leave
your ToolTalk session.
