I was about to say that this is an obvious typo, but no, this code is correct
AFAIK.
The declaration of RaiseException is:
void
WINAPI RaiseException(
__in DWORD dwExceptionCode,
__in DWORD dwExceptionFlags,
__in DWORD nNumberOfArguments,
__in const ULONG_PTR *lpArguments
);
That is, the last argument is an array of arguments to be copied into the
exception record.
In our case, the start of the array is &exc, and its length is 1.
So, the first element of ExceptionInformation will be exc.
Should I add a comment ?
Tristan.
