TTSnoop is a tool provided to create and send custom-constructed ToolTalk messages. You can also use TTSnoop as a tool to selectively monitor any or all ToolTalk messages.
TTSnoop is a useful interactive tool that you can use to become familiar with TookTalk concepts and API calls as well as to perform demonstrations. In addition, TTSnoop is a valuable debugging tool when you are developing applications.
You can use TTSnoop to monitor for messages that match more than one pattern. When a matched message is displayed, the name of the pattern that matched the entry can also be displayed.
You can add, edit, or delete messages and patterns to scrollable lists. TTSnoop allows the definitions of multiple patterns and messages to be saved and loaded from files. You can also define, save, and reload patterns and messages particular to a category of applications (for example, DeskSetTM tools) as well as associate messages and patterns with a user-defined name.
The TTSnoop program resides in the directory /usr/dt/bin/ttsnoop.
To start the program, enter the following command on the command line:
ttsnoop [ -t ]
The -t option displays the ToolTalk API calls that are being used to construct a particular pattern or message. Table 3-1 describes the buttons that are displayed when TTSnoop starts.
