 *  TEST SUITE FOR MB/WC FUNCTIONS IN C LIBRARY
 *
 *       FILE:  dat_mbtowc.c
 *
 *       MBTOWC:  int  mbtowc (wchar_t *wp, char *s, size_t n);
 */

/*  NOTE:
 *
 *       int  mbtowc (wchar_t *wp, char *s, size_t n);
 *
 *       where       n: a maximum number of bytes
 *              return: the number of bytes
 *
 *
 *        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 put a 'NULL', it means a null string as well as "".
 *
 *        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_mbtowc(), set ret_flg=0 always. It's a special case
 *          and the test function takes care of it.
 *
 *                        w_flg
 *                        |     s: (a null string; can't be (char *)NULL)
 *                        |     |
 *             input.   { 1, 0, (char)NULL, MB_LEN_MAX  },
 *                           |
 *                           s_flg=0: makes _s_ a null pointer.
 *
 *             expect   { 0,0,0,x,     0x0000     },
 *                            | |
 *                            | ret_val: 0/+1
 *                            ret_flg=0
 *
 *
 *    Test data for State dependent encodings:
 *
 *        mbtowc( NULL, NULL, 0 );       ... first  data
 *        mbtowc( &wc,  s1,  n1 );       ... second data
 *        mbtowc( &wc,  s2,  n2 );       ... third  data
