I'm reluctantly having to deal with Win32 structured exceptions again. I'm trying to generate a string describing an exception. Most of it is straightforward, but I'm stuck on something basic: how can I convert an exception code (the result of GetExceptionCode()
, or the ExceptionCode
member of an EXCEPTION_RECORD
) into a string describing the exception?
I'm looking for something that will convert eg 0xC0000005 to "Access Violation". Is it just a call to FormatMessage()
?
Yes. It's a NTSTATUS
, so use FORMAT_MESSAGE_FROM_SYSTEM|FORMAT_MESSAGE_FROM_HMODULE
, and pass the HMODULE
from LoadLibrary("NTDLL.DLL")
