It should instead say "(size-1)'th > character" (which is last in the buffer). I think one could argue either way. The character with index (size-1) gets the NUL byte, but if one says that the first character is the one with index 0, then it is in fact the size'th character which receives the NUL. -Ben Kaduk _______________________________________________ freebsd-doc@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-doc To unsubscribe, send any mail to "freebsd-doc-unsubscr...@freebsd.org"
