C++ Throw Exception Destructor at Phoebe Jensen blog

C++ Throw Exception Destructor. As any other function, a destructor may terminate by throwing an exception (this usually requires it to be explicitly declared. Unlike constructors, where throwing exceptions can be a useful way to indicate that object creation succeeded, exceptions should not be. Best practice prior to c++17 says to not let exceptions propagate out of a destructor. When an exception is thrown, destructors of the objects (whose scope ends with the try block) are automatically called before. Throwing exceptions from a destructor the below program shows an example of what happens when an exception gets thrown. For every function that might throw or propagate an exception, provide one of the three exception guarantees: It is fine if a destructor contains a throw. The c++ rule is that you must never throw an exception from a destructor that is being called during the “stack unwinding” process of another.
