Selecting Source Lines

Several of the single-stepping commands require you to select a source line or machine instruction in the Source Pane. To choose a source line, place the cursor over the line and select it. See Displaying Thread and Process Locations for information on what occurs within the Root Window when you select a source line or machine instruction.

If you select a source line that has more than one instantiation (for example, in a C++ function template or code in a header file), TotalView displays its Ambiguous Line dialog box that allows you to select a specific instantiation, as shown in the following figure.

You can now select the function in which the line is located so TotalView can determine where it should place its goal.
