Answer 1

If you think this is what you really want, you can do it like this:

try
{
    try
    {
        //...
    }
    catch( ... )
    {
        //...
        if( .. )
            throw std::runtime_exception( "error occured" );
    }
}
catch( std::runtime_exception& e )
{
    // handle exception of exception handler
}
