Types of Breakpoints
On this page:
Breakpoints are simple but very important debug instrument which allows you to suspend a program upon reaching the certain breakpoint and examine behavior of the program and its components at that point. A breakpoint is defined by one or more conditions that determine when a program's execution should be interrupted. These conditions depend on breakpoint type and configuration.
CLion lets you create breakpoints of several types. Each breakpoint type supported by CLion addresses different debugging needs and has its own individual settings.
CLion enables you to set the following types of breakpoints:
These breakpoints are assigned to lines of source code and are used to target a particular section for debugging.
Line breakpoints are triggered when the program reaches the specified line of source code, before it is executed. The line of code that contains a set breakpoint, is marked with a red stripe; once such line of code is reached, the marking stripe changes to blue.
Exception breakpoints are triggered when the specified exception is thrown or caught, depending on settings. Unlike the line breakpoints, which require specific source references, exception breakpoints apply globally to the exception condition, rather than to a particular code reference.
Symbolic breakpoints stop program execution when a specific function or method starts executing. Symbolic breakpoint can be triggered within a specific module (modules) only or within all modules, as required. Refer to Adding Symbolic Breakpoint for details.
