exception handler

Computing Dictionary

exception handler definition


Special code which is called when an exception occurs during the execution of a program. If the programmer does not provide a handler for a given exception, a built-in system exception handler will usually be called resulting in abortion of the program run and some kind of error indication being returned to the user.
Examples of exception handler mechanisms are Unix's signal calls and Lisp's catch and throw.
