The extra byte is used to store a '\0', allowing the ->buf - * member to be a valid C-string. Every strbuf function ensures this - * invariant is preserved. - * - * Note that it is OK to "play" with the buffer directly if you work it - * that way: - * - * strbuf_grow(sb, SOME_SIZE); - * ... Here, the memory array starting at sb->buf, and of length - * ... strbuf_avail(sb) is all yours, and you are sure that - * ... strbuf_avail(sb) is at least SOME_SIZE. - * strbuf_setlen(sb, sb->len + SOME_OTHER_SIZE); - * - * Of course, SOME_OTHER_SIZE must be smaller or equal to strbuf_avail(sb). - * - * Doing so is safe, though if it has to be done in many places, adding the - * missing API to the strbuf module is the way to go. - * - * XXX: do _not_ assume that the area that is yours is of size ->alloc - 1 - * even if it's true in the current implementation.
