Examining Code Paths Using Thread Display
You can use the thread display to examine code paths. To launch the thread display:
Click the Summary (Live) tab of the Code Display window.
Click the New Window button to the right of the Threads subsection.
The thread display will launch in a separate window, as exemplified below.
At the top of the thread display appears a count of the total number of running threads for the application being debugged. A summary of data for each thread then appears as a list in the thread display. This data includes:
• The name of each thread.
• The name of the module to which the thread belongs.
• The state for each thread.
• The number of statements associated with each thread.
To the right of each thread summary appear three buttons:
Previous Statement: The previous statement button (represented by a downward pointing arrow icon) can be clicked to allow you to move backward through the execution history.
Next Statement: The next statement button (represented by an upward pointing arrow icon) can be clicked to allow you to move forward through the execution history.
Show/Hide: The Show/Hide button can be clicked to display or hide the statement data that is provided for each thread.
Statements that belong to a thread are listed when the Show/Hide button is clicked. For each statement, the time (in milliseconds) is displayed, along with the name of the module and the state to which each statement belongs, and the statement number.
Note: Looking at the time column provides you with a history of recent actions. A gap in time will be reflected if an action is stopped or a breakpoint has been met.
You can double-click on a statement to have the module tree highlight the associated module. If you click on a statement in the thread display you will be taken to the appropriate line of code.
Note: VTS also includes the Thread List Application, which you may use to analyze your VTS applications.
