| <p>The function creates an exception handler functional object. The handler will call to the user-specified functional object with an exception as its argument. If the exception type cannot be identified, the handler will call the user-defined functor with no arguments, instead of propagating exception to the caller.</p> |
| <p>This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.</p> |
