I was looking at the differences between some old FreeBSD code and the one of 7.0-RC1 and was wondering about a change in inet_ntoa.c /***** 7.0-RC1 **************/ sprintf(buf, "%d.%d.%d.%d", ucp[0] & 0xff, ucp[1] & 0xff, ucp[2] & 0xff, ucp[3] & 0xff); /****** 4.11-RELEASE ***********/ static const char fmt[] = "%u.%u.%u%u"; if ((size_t)snprintf(dst, size, fmt, src[0], src[1], src[2], src[3]) >= size) { .... .... Was there a specific purpose of changing the more easy and simple way of %u instead of the combination of %d and and-ing with 0xff ?? It essentially gives the same result but increases overhead (i think) in the more recent version.
