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