     input: a null-terminated input string
     str_list: a PRE-ALLOCATED array of character pointers. This must be
       at least of size str_list[max_lines][max_width]
     width: the desired number of characters per line. Note that words
       with more characters than "width" are not hypenated, so it's
       possible to get a line that is longer than "width."
     max_lines and max_width: memory-safety parameters for str_list
       (see above)

   On output, linewrap returns the number of lines used to format the
   string.
