For example, if an exception is thrown as >in The required behaviour is a call to std::terminate(). The default behaviour of std::terminate() is to call std::abort(). You can change the default behaviour at your option by using the function std::set_terminate(void (*)()). Coding guideline: try to make your exception objects not throw. To avoid risking to throw an out-of-memory or std::bad_alloc, avoid dynamic memory in the exception object. Coding guideline: try to make your destructors of exception as well as non-exception objects not throw. If an object is being destroyed because of an exception already in progress, then if the destructor throws, we have two exceptions. The result is a call to std::terminate(). -- -------------- siemel b naran -------------- [ comp.std.c++ is moderated. To submit articles, try just posting with ] [ your news-reader.
