I'm a little surprised by this question. Are you saying that *no*
paths return a value and you declare the function as non void?
Maybe you were referring to a situation like this?
// The throw is conditional, and there's at
// least one path that does return a value
//
template <typename ExceptionT>
void do_throw(ExceptionT const & ex) { throw ex; }
int f() {
for ( ...)
if (...)
return somevalue;
do_throw( some_exception() );
}
Genny.
