Vectored Exception Handling

Microsoft Vectored Exception Handling (VEH) is an exception handling mechanism that complements the Structured Exception Handling mechanism. It is available on the Windows NT family of operating systems, starting with Windows XP. It was extended in Windows Server 2003.

Vectored Exception Handling

Vectored Exception Handling is made available to Windows programmers using languages such as C++ and Visual Basic. VEH does not replace Structured Exception Handling (SEH), rather VEH and SEH coexist, with VEH handlers having priority over SEH handlers. Compared with SEH, VEH works more like a traditional notification callback scheme.
