9 /* NOTE:
10 *
11 * int mbtowc (wchar_t *wp, char *s, size_t n);
12 *
13 * where n: a maximum number of bytes
14 * return: the number of bytes
15 *
16 *
17 * o When you feed a null pointer for a string (s) to the function,
18 * set s_flg=0 instead of putting just a 'NULL' there.
19 * Even if you put a 'NULL', it means a null string as well as "".
20 *
21 * o When s is a null pointer, the function checks state dependency.
22 *
23 * state-dependent encoding - return NON-zero
24 * state-independent encoding - return 0
25 *
26 * If state-dependent encoding is expected, set
27 *
28 * s_flg = 0, ret_flg = 0, ret_val = +1
29 *
30 * If state-independent encoding is expected, set
31 *
32 * s_flg = 0, ret_flg = 0, ret_val = 0
33 *
34 *
35 * When you set ret_flg=1, the test program simply compares
36 * an actual return value with an expected value. You can
37 * check state-independent case (return value is 0) in that
38 * way, but you can not check state-dependent case. So when
39 * you check state- dependency in this test function:
40 * tst_mbtowc(), set ret_flg=0 always. It's a special case
41 * and the test function takes care of it.
42 *
43 * w_flg
44 * | s: (a null string; can't be (char *)NULL)
45 * | |
46 * input. { 1, 0, (char)NULL, MB_LEN_MAX },
47 * |
48 * s_flg=0: makes _s_ a null pointer.
49 *
50 * expect { 0,0,0,x, 0x0000 },
51 * | |
52 * | ret_val: 0/+1
53 * ret_flg=0
54 *
55 *
56 * Test data for State dependent encodings:
57 *
58 * mbtowc( NULL, NULL, 0 ); ... first data
59 * mbtowc( &wc, s1, n1 ); ... second data
60 * mbtowc( &wc, s2, n2 ); ... third data
