Watchpoints are a type of breakpoints, i.e. are used to suspend the program execution in the debug mode.
Unlike breakpoints (that are line-specific), watchpoints are associated with files.
Watchpoints are attached to a variable or an expression that is evaluated continually as the application is executed.
You can also set a watchpoint on an expression even if the expression can not be evaluated yet.
Use watchpoints if you want to interrupt a program when the contents of a field or structure change.
