The SBUF_INCLUDENUL flag causes the nulterm byte at the end of the string to be counted in the length of the data. If copying the data using the sbuf_data() and sbuf_len() functions, or if writing it automatically with a drain function, the net effect is that the nulterm byte is copied along with the rest of the data.
