What is the point of `void func() throw(type)`?

Question

I know this is a valid c++ program. What is the point of the throw in the function declarement? AFAIK it does nothing and isnt used for anything.

#include &l         


        

Answer 1

Exception specification. The type(s) following the throw keyword specifies exactly what all, if any, exceptions the function can throw. See 15.4 of the draft.

Note: A function with no exception-specification allows all exceptions. A function with an empty exception-specification, throw(), does not allow any exceptions.
