INTRODUCTION

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

The following are standard exception errors: 

   EXCEPTION_ACCESS_VIOLATION
   EXCEPTION_ARRAY_BOUNDS_EXCEEDED
   EXCEPTION_BREAKPOINT
   EXCEPTION_DATATYPE_MISALIGNMENT
   EXCEPTION_FLT_DENORMAL_OPERAND
   EXCEPTION_FLT_DIVIDE_BY_ZERO
   EXCEPTION_FLT_INEXACT_RESULT
   EXCEPTION_FLT_INVALID_OPERATION
   EXCEPTION_FLT_OVERFLOW
   EXCEPTION_FLT_STACK_CHECK
   EXCEPTION_FLT_UNDERFLOW
   EXCEPTION_ILLEGAL_INSTRUCTION
   EXCEPTION_IN_PAGE_ERROR
