Pattern Languages for Handling C++ Resources in an Exception-Safe Way

Harald M. M|ller
Siemens AG Austria


Using exception handling in C++ can lead to severe problems with dynamic objects and other resources- dangling pointers, memory leaks etc. By using a small set of patterns (collected into a pattern language "Ex- ception-safe C++ objects"), these problems can be avoided. However, it turns out that these pattern make use of "resource management", which poses a lot of questions in itself. For the solution of these problems, a second, somewhat larger set of patterns (collected into a pattern language "Responsibility management under exception handling") is provided.
