CreateEvent returns an EFI_STATUS. It expects the OUT parameter, a pointer to an EFI_EVENT, to be non-NULL. A null pointer results in EFI_INVALID_PARAMETER. If the CreateEvent is successful, then `event` points to the newly created event. It's the caller's responsibility to pass a pointer to valid writable memory.
