Introduces the concept of exception handling for handling program errors.

Shows what object construction, and construction failure, mean in C++; and that function try blocks are useful to translate an exception thrown from a base or member subobject constructor.

It is becoming increasingly popular to consider throwing destructors a bad practice. This document presents some insights on the problem and shows that maybe throwing from a destructor is not such a bad idea.

Describes an optimization that produces modest but useful gains on some existing C++ code, but produces very significant size and speed gains on code that uses empty exception specifications, avoiding otherwise serious performance losses.

Presents some guidelines when to use exceptions.

The ACCU is a non-profit organisation devoted to professionalism in programming at all levels. Although primarily focussed on C and C++, they also have interests in Java, C# and Python.

Learn how to throw an exception, how to associate handlers, or catch clauses, with a set of program statements using a try block, how exceptions are handled by catch clauses, exception specifications, and design considerations for programs that use exceptions.

Lessons learned from specifying exception-safety for the C++ standard library.

Reviews guidelines developed years ago for throwing exceptions and how to use exception specifications.

This article describes a simple method of adding exhaustive testing of the exception paths to the test suite.

Constructor Tracking - Talks about dealing with exceptions that occur during object initialization by taking a look at smart_ptr initialization that has important teachings for any generic design - and policy-based classes in particular. (Andrei Alexandrescu and David B. Held)

Discusses how to analyze the exception safety of a function. (Andrei Alexandrescu and David B. Held)

An indepth discussion of how VC++ implements exception handling. Source code includes exception handling library for VC++.

Explains why most members of the C++ community vastly underestimate the skills needed to program with exceptions and therefore underestimate the true costs of their use. By Tom Cargill.
