       If dest is not NULL, the wcsrtombs()  function converts the
       wide-character string *src to a multibyte string starting at dest.  At
       most size bytes are written to dest.  The shift state *ps is updated.
       The conversion is effectively performed by repeatedly calling
       wcrtomb(dest, *src, ps), as long as this call succeeds, and then
       incrementing dest by the number of bytes written and *src by one.  The
       conversion can stop for three reasons:

          <?><?><?><?><?><?><?><?><?> <?><?><?><?><?><?><?>). <?> <?><?><?><?>

          (size_t) -1, <?> <?><?><?><?><?><?><?><?> errno
          <?><?><?><?><?><?><?><?><?><?> <?><?><?><?><?><?> EILSEQ.

       o  The size limit forces a stop.  In this case, *src is left pointing
          to the next wide character to be converted, and the number of bytes
          written to dest is returned.

       o  The wide-character string has been completely converted, including
          the terminating null wide character (L'\0'), which has the side
          effect of bringing back *ps to the initial state.  In this case,
          *src is set to NULL, and the number of bytes written to dest,
          excluding the terminating null byte ('\0'), is returned.

       If dest is NULL, size is ignored, and the conversion proceeds as above,
       except that the converted bytes are not written out to memory, and that
       no size limit exists.

       The programmer must ensure that there is room for at least size bytes
       at dest.
