The result should be positive, certainly, as it's later used as either a file offset (with a printed warning) and as a size_t. But I'm more inclined to keep it common with the other values here, and use `file_ptr`, which is a signed integer type like `off_t` and `ssize_t`. Ok, that's fine with me. Simon
