You can set or delete a breakpoint at a specific function or source-line number without having to first find the function or source line in the Source Pane. Do this by entering a line number or function name in the Action Point > At Location Dialog Box.

When you’re done, TotalView sets a breakpoint at the location. If you enter a function name, TotalView sets the breakpoint at the function’s first executable line. In either case, if a breakpoint already exists at a location, TotalView deletes it.

For detailed information about the kinds of information you can enter in this dialog box, see dbreak in the TotalView for HPC Reference Guide.
