);
exceptionNum
The identifier for the exception.
exceptionPtr
A pointer to the exception information.
An integer that indicates the action to be taken, based on the result of exception processing.
These methods are called by the exception-filter expression of the try-except Statement. The method consults a constant internal table to identify the exception and determine the appropriate action, as shown here. The exception numbers are defined in winnt.h and the signal numbers are defined in signal.h.
