OK. I think that would be more clear if we tested foffset. How about if (foffset == 0) /* Invalid CBFS entry that would cause an infinite loop */ return NULL;
Or we could just test foffset when we test the magic number.
The problem is that we can't trust _anything_ in that array: there's no final entry in the chain, so the data after that is garbage. You still have an endless loop for (foffset == 4) && (flen == -4) We could do if (foffset + flen == 0) return NULL; but I wonder why we shouldn't just do the full test then, with some comment to the same effect as yours above.
