No, if the resource is not found, lpBuffer remains unchanged on Windows and isn't set to NULL.
I could of course set it to NULL beforehand instead of setting SetLastError. But the current solution uses less code than that. (Except of course I should use "SetLastError(ERROR_SUCCESS)" instead of S_OK, as you noted.) Which one do you prefer?
