Many exception errors are not processed by applications. The most commonexception error is EXCEPTION_ACCESS_VIOLATION (c0000005). It occurs when apointer is dereferenced and the pointer points to inaccessible memory or awrite operation is attempted on read-only memory. If an application doesnot trap an exception, the Win32 module, UnhandledExceptionFilter, will doone of the following: display a message box, invoke Dr. Watson, or attachyour application to a debugger.
