Method breakpoints are set on methods that do not have source code. To set a method breakpoint on a line of source code:
The Outline view appears displaying an outline of the structured elements of the C/C++ file that is currently open in the editor area.
A breakpoint appears in the Breakpoints view. A breakpoint appears on the marker bar in the file's editor for the method that was selected, if source code exists for the class.
When the breakpoint is enabled, thread execution suspends before the method enters or exits.
