Hi,
windows.inc defines EXCEPTION_NONCONTINUABLE constant, but the others seems to be missing. The identifiers of the following constants were inspired by exsup.inc, distributed with MSVS or MSVC++, and also by Matt Pietrek's nice paper about SEH (http://www.microsoft.com/msj/0197/exception/exceptiontextfigs.htm#fig5):
EXCEPTION_UNWINDING EQU 2
EXCEPTION_EXIT_UNWIND EQU 4
EXCEPTION_UNWIND_CONTEXT EQU EXCEPTION_UNWINDING OR EXCEPTION_EXIT_UNWIND
EXCEPTION_STACK_INVALID EQU 8
EXCEPTION_NESTED_CALL EQU 10h
It would be nice to see those constants in windows.inc too :green
