20 /* The macros in this file implement forward iteration through a
21 multi-byte string, without knowing its length a-priori.
22
23 With these macros, an iteration loop that looks like
24
25 char *iter;
26 for (iter = buf; *iter != '\0'; iter++)
27 {
28 do_something (*iter);
29 }
30
31 becomes
32
33 mbui_iterator_t iter;
34 for (mbui_init (iter, buf); mbui_avail (iter); mbui_advance (iter))
35 {
36 do_something (mbui_cur_ptr (iter), mb_len (mbui_cur (iter)));
37 }
38
39 The benefit of these macros over plain use of mbrtowc is:
40 - Handling of invalid multibyte sequences is possible without
41 making the code more complicated, while still preserving the
42 invalid multibyte sequences.
43
44 Compared to mbiter.h, the macros here don't need to know the string's
45 length a-priori. The downside is that at each step, the look-ahead
46 that guards against overrunning the terminating '\0' is more expensive.
47 The mbui_* macros are therefore suitable when there is a high probability
48 that only the first few multibyte characters need to be inspected.
49 Whereas the mbi_* macros are better if usually the iteration runs
50 through the entire string.
51
52 mbui_iterator_t
53 is a type usable for variable declarations.
54
55 mbui_init (iter, startptr)
56 initializes the iterator, starting at startptr.
57
58 mbui_avail (iter)
59 returns true if there are more multibyte chracters available before
60 the end of string is reached. In this case, mbui_cur (iter) is
61 initialized to the next multibyte chracter.
62
63 mbui_advance (iter)
64 advances the iterator by one multibyte character.
65
66 mbui_cur (iter)
67 returns the current multibyte character, of type mbchar_t. All the
68 macros defined in mbchar.h can be used on it.
69
70 mbui_cur_ptr (iter)
71 return a pointer to the beginning of the current multibyte character.
72
73 mbui_reloc (iter, ptrdiff)
74 relocates iterator when the string is moved by ptrdiff bytes.
75
76 Here are the function prototypes of the macros.
77
78 extern void mbui_init (mbui_iterator_t iter, const char *startptr);
79 extern bool mbui_avail (mbui_iterator_t iter);

112
113 1) Is this safe? Will it catch all the zero bytes?
114 Suppose there is a byte with all zeros. Any carry bits
115 propagating from its left will fall into the hole at its
116 least significant bit and stop. Since there will be no
117 carry from its most significant bit, the LSB of the
118 byte to the left will be unchanged, and the zero will be
119 detected.
120
121 2) Is this worthwhile? Will it ignore everything except
122 zero bytes? Suppose every byte of LONGWORD has a bit set
123 somewhere. There will be a carry into bit 8. If bit 8
124 is set, this will carry into bit 16. If bit 8 is clear,
125 one of bits 9-15 must be set, so there will be a carry
126 into bit 16. Similarly, there will be a carry into bit
127 24. If one of bits 24-30 is set, there will be a carry
128 into bit 31, so all of the hole bits will be changed.
129
130 The one misfire occurs when bits 24-30 are clear and bit
131 31 is set; in this case, the hole at bit 31 is not
132 changed. If we had access to the processor carry flag,
133 we could close this loophole by putting the fourth hole
134 at bit 32!
135
136 So it ignores everything except 128's, when they're aligned
137 properly.
138
139 3) But wait! Aren't we looking for C, not zero?
140 Good point. So what we do is XOR LONGWORD with a longword,
141 each of whose bytes is C. This turns each byte that is C

24
25 Programs that use <stdbool.h> should be aware of some limitations
26 and standards compliance issues.
27
28 Standards compliance:
29
30 - <stdbool.h> must be #included before 'bool', 'false', 'true'
31 can be used.
32
33 - You cannot assume that sizeof (bool) == 1.
34
35 - Programs should not undefine the macros bool, true, and false,
36 as C99 lists that as an "obsolescent feature".
37
38 Limitations of this substitute, when used in a C89 environment:
39
40 - <stdbool.h> must be #included before the '_Bool' type can be used.
41
42 - You cannot assume that _Bool is a typedef; it might be a macro.
43
44 - In C99, casts and automatic conversions to '_Bool' or 'bool' are
45 performed in such a way that every nonzero value gets converted
46 to 'true', and zero gets converted to 'false'. This doesn't work
47 with this substitute. With this substitute, only the values 0 and 1
48 give the expected result when converted to _Bool' or 'bool'.
49
50 Also, it is suggested that programs use 'bool' rather than '_Bool';
51 this isn't required, but 'bool' is more common. */

69 this, values of type '_Bool' may promote to 'int' or 'unsigned int'
70 (see ISO C 99 6.7.2.2.(4)); however, '_Bool' must promote to 'int'
71 (see ISO C 99 6.3.1.1.(2)). So we add a negative value to the
