+/*
+ *  NOTE:
+ *       int  mblen (char *s, size_t n);
+ *
+ *       where      n: a maximum number of bytes
+ *
+ *       return - the number of bytes
+ *
+ *  CAUTION:
+ *
+ *      o When you feed a null pointer for a string (s) to the function,
+ *        set s_flg=0 instead of putting just a 'NULL' there.
+ *        Even if you set a 'NULL', it doens't mean a NULL pointer.
+ *
+ *      o When s is a null pointer, the function checks state dependency.
+ *
+ *            state-dependent encoding      - return  NON-zero
+ *            state-independent encoding    - return  0
+ *
+ *        If state-dependent encoding is expected, set
+ *
+ *            s_flg = 0,  ret_flg = 0,  ret_val = +1
+ *
+ *        If state-independent encoding is expected, set
+ *
+ *            s_flg = 0,  ret_flg = 0,  ret_val = 0
+ *
+ *
+ *        When you set ret_flg=1, the test program simply compares an
+ *        actual return value with an expected value. You can check
+ *        state-independent case (return value is 0) in that way, but
+ *        you can not check state-dependent case. So when you check
+ *        state- dependency in this test function: tst_mblen(), set
+ *        ret_flg=0 always. It's a special case, and the test
+ *        function takes care of it.
+ *
+ *            s_flg=0           ret_flg=0
+ *            |                 |
+ *          { 0, 0 },   { 0, 0, 0,  x }
+ *               |                  |
+ *               not used           ret_val: 0/+1
+ *                                  (expected val) */
