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.
About TTSnoop
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.
Where to Find TTSnoop
The TTSnoop program resides in the directory /usr/dt/bin/ttsnoop.
Starting 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.

Composing and Registering Patterns
When you click the Patterns button on the main display window, a display panel is displayed.
Click the Apply button to register your pattern. Once a pattern is registered, you can use TTSnoop as a debugging tool to observe what messages are being sent by other applications.

Displaying Message Components
When you click the Display button on the main display window, a display panel of checkboxes is displayed.
When you select a checkbox and click the Apply button, the specified ToolTalk message component is displayed until you make another selection and apply the change.
Sending Pre-Created Messages
When you click the Send Message button on the main display window, you can send one of the messages you created and stored using the Messages display.
Receiving Messages
When you click the Start button on the main display window, TTSnoop will display any incoming messages that match the patterns you registered.
Stop Receiving Messages
When you click the Stop button on the main display window, TTSnoop will stop receiving messages.
