34 * Version 0.1.16.0
35 *
36 * The ANSI C standard committee, for the C99 standard, specified the
37 * inclusion of a new standard include file called stdint.h. This is
38 * a very useful and long desired include file which contains several
39 * very precise definitions for integer scalar types that is critically
40 * important for making several classes of applications portable
41 * including cryptography, hashing, variable length integer libraries
42 * and so on. But for most developers its likely useful just for
43 * programming sanity.
44 *
45 * The problem is that some compiler vendors chose to ignore the C99
46 * standard and some older compilers have no opportunity to be updated.
47 * Because of this situation, simply including stdint.h in your code
48 * makes it unportable.
49 *
50 * So that's what this file is all about. It's an attempt to build a
51 * single universal include file that works on as many platforms as
52 * possible to deliver what stdint.h is supposed to. Even compilers
53 * that already come with stdint.h can use this file instead without
54 * any loss of functionality. A few things that should be noted about
55 * this file:
56 *
57 * 1) It is not guaranteed to be portable and/or present an identical
58 * interface on all platforms. The extreme variability of the
59 * ANSI C standard makes this an impossibility right from the
60 * very get go. Its really only meant to be useful for the vast
61 * majority of platforms that possess the capability of
62 * implementing usefully and precisely defined, standard sized
63 * integer scalars. Systems which are not intrinsically 2s
64 * complement may produce invalid constants.
65 *
66 * 2) There is an unavoidable use of non-reserved symbols.
67 *
68 * 3) Other standard include files are invoked.
69 *
70 * 4) This file may come in conflict with future platforms that do
71 * include stdint.h. The hope is that one or the other can be
72 * used with no real difference.
73 *
74 * 5) In the current version, if your platform can't represent
75 * int32_t, int16_t and int8_t, it just dumps out with a compiler
76 * error.
77 *
78 * 6) 64 bit integers may or may not be defined. Test for their
79 * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
80 * Note that this is different from the C99 specification which
81 * requires the existence of 64 bit support in the compiler. If
82 * this is not defined for your platform, yet it is capable of
83 * dealing with 64 bits then it is because this file has not yet
84 * been extended to cover all of your system's capabilities.
85 *
86 * 7) (u)intptr_t may or may not be defined. Test for its presence
87 * with the test: #ifdef PTRDIFF_MAX. If this is not defined
88 * for your platform, then it is because this file has not yet
89 * been extended to cover all of your system's capabilities, not
90 * because its optional.
91 *
92 * 8) The following might not been defined even if your platform is
93 * capable of defining it:
94 *
95 * WCHAR_MIN
96 * WCHAR_MAX
97 * (u)int64_t
98 * PTRDIFF_MIN
99 * PTRDIFF_MAX
100 * (u)intptr_t
101 *
102 * 9) The following have not been defined:
103 *
104 * WINT_MIN
105 * WINT_MAX
106 *
107 * 10) The criteria for defining (u)int_least(*)_t isn't clear,
108 * except for systems which don't have a type that precisely
109 * defined 8, 16, or 32 bit types (which this include file does
110 * not support anyways). Default definitions have been given.
111 *
112 * 11) The criteria for defining (u)int_fast(*)_t isn't something I
113 * would trust to any particular compiler vendor or the ANSI C
114 * committee. It is well known that "compatible systems" are
115 * commonly created that have very different performance
116 * characteristics from the systems they are compatible with,
117 * especially those whose vendors make both the compiler and the
118 * system. Default definitions have been given, but its strongly
119 * recommended that users never use these definitions for any
120 * reason (they do *NOT* deliver any serious guarantee of
121 * improved performance -- not in this file, nor any vendor's
122 * stdint.h).
123 *
124 * 12) The following macros:
125 *
126 * PRINTF_INTMAX_MODIFIER
127 * PRINTF_INT64_MODIFIER
128 * PRINTF_INT32_MODIFIER
129 * PRINTF_INT16_MODIFIER
130 * PRINTF_LEAST64_MODIFIER
131 * PRINTF_LEAST32_MODIFIER
132 * PRINTF_LEAST16_MODIFIER
133 * PRINTF_INTPTR_MODIFIER
134 *
135 * are strings which have been defined as the modifiers required
136 * for the "d", "u" and "x" printf formats to correctly output
137 * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
138 * (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
139 * PRINTF_INTPTR_MODIFIER is not defined for some systems which
140 * provide their own stdint.h. PRINTF_INT64_MODIFIER is not
141 * defined if INT64_MAX is not defined. These are an extension
142 * beyond what C99 specifies must be in stdint.h.
143 *
144 * In addition, the following macros are defined:
145 *
146 * PRINTF_INTMAX_HEX_WIDTH
147 * PRINTF_INT64_HEX_WIDTH
148 * PRINTF_INT32_HEX_WIDTH
149 * PRINTF_INT16_HEX_WIDTH
150 * PRINTF_INT8_HEX_WIDTH
151 * PRINTF_INTMAX_DEC_WIDTH
152 * PRINTF_INT64_DEC_WIDTH
153 * PRINTF_INT32_DEC_WIDTH
154 * PRINTF_INT16_DEC_WIDTH
155 * PRINTF_UINT8_DEC_WIDTH
156 * PRINTF_UINTMAX_DEC_WIDTH
157 * PRINTF_UINT64_DEC_WIDTH
158 * PRINTF_UINT32_DEC_WIDTH
159 * PRINTF_UINT16_DEC_WIDTH
160 * PRINTF_UINT8_DEC_WIDTH
161 *
162 * Which specifies the maximum number of characters required to
163 * print the number of that type in either hexadecimal or decimal.
164 * These are an extension beyond what C99 specifies must be in
165 * stdint.h.
166 *
167 * Compilers tested (all with 0 warnings at their highest respective
168 * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
169 * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
170 * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
171 *
172 * This file should be considered a work in progress. Suggestions for
173 * improvements, especially those which increase coverage are strongly
174 * encouraged.
