Stepping Through a Program
To start and step through your program, the easiest way is to use the buttons on the Process Window’s toolbar:
• To start and stop your program:
— Set a breakpoint, then select Go in the toolbar. Your program starts executing. Execution stops just before the line that contains a breakpoint or when you click Halt.
— Select Next. TotalView starts your program, and then stops it immediately before the first statement in your main() function.
• To stop a running program, select the toolbar’s Halt button. To restart a program, select the toolbar’s Restart button.
• To step through your program, use the Step and Next buttons. Both tell your program to execute the current line, but when a line has a function call
— Step goes into the function
— Next completely executes the function
If you want to get to a line without individually stepping each line in between, select the line (not the line number) to highlight it, then click the Run To button.
• To step out of a function:
If you stepped into a function and want to pop out to the statement that called it, click the Out button.
