Actually, that's the first reference so far to say that a kernel level error code is the same as a userspace exception code. If it is, then it's safe to use as such.

If these are indeed the same as userspace exceptions, then you can load ntdll to get those. If you don't load ntdll, you can only look at "normal errors". //Magnus ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
