  11  *  NOTE:
  12  *        int  mblen (char *s, size_t n);
  13  *
  14  *        where      n: a maximum number of bytes
  15  *
  16  *        return - the number of bytes
  17  *
  18  *  CAUTION:
  19  *
  20  *       o When you feed a null pointer for a string (s) to the function,
  21  *         set s_flg=0 instead of putting just a 'NULL' there.
  22  *         Even if you set a 'NULL', it doens't mean a NULL pointer.
  23  *
  24  *       o When s is a null pointer, the function checks state dependency.
  25  *
  26  *             state-dependent encoding      - return  NON-zero
  27  *             state-independent encoding    - return  0
  28  *
  29  *         If state-dependent encoding is expected, set
  30  *
  31  *             s_flg = 0,  ret_flg = 0,  ret_val = +1
  32  *
  33  *         If state-independent encoding is expected, set
  34  *
  35  *             s_flg = 0,  ret_flg = 0,  ret_val = 0
  36  *
  37  *
  38  *         When you set ret_flg=1, the test program simply compares an
  39  *         actual return value with an expected value. You can check
  40  *         state-independent case (return value is 0) in that way, but
  41  *         you can not check state-dependent case. So when you check
  42  *         state- dependency in this test function: tst_mblen(), set
  43  *         ret_flg=0 always. It's a special case, and the test
  44  *         function takes care of it.
  45  *
  46  *             s_flg=0           ret_flg=0
  47  *             |                 |
  48  *           { 0, 0 },   { 0, 0, 0,  x }
  49  *                |                  |
  50  *                not used           ret_val: 0/+1
  51  *                                   (expected val) */
