cpp: catch exception with ellipsis and see the information

I know that you can catch "all exceptions" and print the exception by 

try
{
    //some code...
}catch(const std::exception& e) {
   cout << e.what();
}

but this is just for exceptions derived from std::exception. I was wondering if there is a way to get some information from an ellipsis catch

try
{
    //some code...
}catch(...) {
   // ??
}

If the mechanism is the same as ellipsis for functions then I should be able to do something like casting the argument of the va_list and trying to call the what() method.

I haven't tried it yet but if someone knows the way I'd be excited to know how.

Solution

  • Sorry, you can't do that. You can only access the exception object in a catch block for a specific exception type.
