What exception does map throw

Hi everyone,

I'm finally writing some code to use a map.  I've never used them
before so this is exciting.  I'm wondering what exception does the
map<> container object through if a key requested does not exist in
the map?  I don't have a good reference for the STL (I'm using my C++
programming book, "Object-Oriented Programming in C++," by Robert
LaFore which has already proven inaccurate a few times and doesn't
cover in depth the STL).  The program I'm writing I definitely want it
to recover if the key isn't found in the map.

Thanks,
Andy
