C++ Blank Throw Statement

Hi. This may seem like a newbie question, but its not.
See, I have NO IDEA how to catch a BLANK throw stement.

(e.g.)

try{   throw;   }
catch(?)// No idea what to put to catch the blank throw statement above
{}

Let's see if anyone can figure this out, eh?
Chears!

What's so intriguing about it, and what part of it requires smarts? An exception thrown in one catch block will never be caught by another catch belonging to the same try.
