Registering with the ToolTalk Service

Before you can participate in ToolTalk sessions, you must register your process with the ToolTalk service. You can either register in the ToolTalk session in which the application was started (the initial session), or locate another session and register there.

The ToolTalk functions you need to register with the ToolTalk service are shown in Table 7–1.
