Well, better answering late than never. By default a function may
throw any exception which will be handled outside this
function. However, the list of exceptions to be thrown by a function
may be limited with "throw" qualifier in the function head/prototype:


  returnVal functionName(parameterList) throw (exceptionType1, exceptionType2);

If this qualifier is stated, and the function throws an exception of
the type that is not listed in its head/prototype than a special
function unexpected() is invoked. By default, this function terminates
the program. Empty list of thrown exceptions:

  returnVal functionName(parameterList) throw ();

Means that the function is not expected to throw any.
