       int buffer_feed(buffer* b);

DESCRIPTION

       If the string is nonempty, buffer_feed returns the length of the string.  If the string is
       empty, buffer_feed uses the read operation to feed data into the string; it  then  returns
       the new length of the string, or 0 for end of input, or -1 for error.
