I'd forgotten that some libc-s return -1 meaning truncation. The problem with that is that some other platforms might use -1 to mean parameter errors. For example, in rather contrived situations, Windows can return -1 on NULL buffer input. I see a couple of options: 1) Add a configure test and config.h variable for if -1 means truncation or not. 2) Just memset the buffer to zero right at the start and then make the change you suggest. I think the second is the easiest and most sensible option.
