0xC000002B is an NTSTATUS code which resolves to STATUS_PARITY_ERROR
.
There is no contractual agreement that a value stored here is a standard Win32 error code. The documentation for GetLastError
vaguely implies this:
The error codes returned by a function are not part of the Windows API specification and can vary by operating system or device driver. For this reason, we cannot provide the complete list of error codes that can be returned by each function
The standard error codes are well documented, so the above statement wouldn't make much sense if all possible results are initially understood.
Note that some WINAPIs can also return HRESULT values.
