Boost Exception provides a namespace-scope function diagnostic_information which takes a boost::exception. The returned string contains:

The returned string is not presentable as a friendly user message, but because it is generated automatically, it is useful for debugging or logging purposes. Here is an example:

#include <boost/exception.hpp>
#include <iostream>

void f(); //throws unknown types that derive from boost::exception.

void
g()
    {
    try
        {
        f();
        }
    catch(
    boost::exception & e )
        {
        std::cerr << diagnostic_information(e);
        }
    }
