[QUOTE="Peter Nilsson, post: 2959110"] In other words, code as... static char buf[1024]; size_t r = fread(buf, 1, sizeof buf, fp); ....rather than... static char buf[1024]; size_t r = fread(buf, sizeof buf, 1, fp); Assuming no read errors, if there are 123 characters left in the stream, the former will return 0 into r, whereas the latter will return 123. Both calls will read the same number of characters though. [/QUOTE]
