34 * Version 0.1.11
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
40 * critically important for making portable several classes of
41 * applications including cryptography, hashing, variable length
42 * integer libraries and so on. But for most developers its likely
43 * useful just for programming sanity.
44 *
45 * The problem is that most compiler vendors have decided not to
46 * implement the C99 standard, and the next C++ language standard
47 * (which has a lot more mindshare these days) will be a long time in
48 * coming and its unknown whether or not it will include stdint.h or
49 * how much adoption it will have. Either way, it will be a long time
50 * before all compilers come with a stdint.h and it also does nothing
51 * for the extremely large number of compilers available today which
52 * do not include this file, or anything comparable to it.
53 *
54 * So that's what this file is all about. Its an attempt to build a
55 * single universal include file that works on as many platforms as
56 * possible to deliver what stdint.h is supposed to. A few things
57 * that should be noted about this file:
58 *
59 * 1) It is not guaranteed to be portable and/or present an identical
60 * interface on all platforms. The extreme variability of the
61 * ANSI C standard makes this an impossibility right from the
62 * very get go. Its really only meant to be useful for the vast
63 * majority of platforms that possess the capability of
64 * implementing usefully and precisely defined, standard sized
65 * integer scalars. Systems which are not intrinsically 2s
66 * complement may produce invalid constants.
67 *
68 * 2) There is an unavoidable use of non-reserved symbols.
69 *
70 * 3) Other standard include files are invoked.
71 *
72 * 4) This file may come in conflict with future platforms that do
73 * include stdint.h. The hope is that one or the other can be
74 * used with no real difference.
75 *
76 * 5) In the current verison, if your platform can't represent
77 * int32_t, int16_t and int8_t, it just dumps out with a compiler
78 * error.
79 *
80 * 6) 64 bit integers may or may not be defined. Test for their
81 * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
82 * Note that this is different from the C99 specification which
83 * requires the existence of 64 bit support in the compiler. If
84 * this is not defined for your platform, yet it is capable of
85 * dealing with 64 bits then it is because this file has not yet
86 * been extended to cover all of your system's capabilities.
87 *
88 * 7) (u)intptr_t may or may not be defined. Test for its presence
89 * with the test: #ifdef PTRDIFF_MAX. If this is not defined
90 * for your platform, then it is because this file has not yet
91 * been extended to cover all of your system's capabilities, not
92 * because its optional.
93 *
94 * 8) The following might not been defined even if your platform is
95 * capable of defining it:
96 *
97 * WCHAR_MIN
98 * WCHAR_MAX
99 * (u)int64_t
100 * PTRDIFF_MIN
101 * PTRDIFF_MAX
102 * (u)intptr_t
103 *
104 * 9) The following have not been defined:
105 *
106 * WINT_MIN
107 * WINT_MAX
108 *
109 * 10) The criteria for defining (u)int_least(*)_t isn't clear,
110 * except for systems which don't have a type that precisely
111 * defined 8, 16, or 32 bit types (which this include file does
112 * not support anyways). Default definitions have been given.
113 *
114 * 11) The criteria for defining (u)int_fast(*)_t isn't something I
115 * would trust to any particular compiler vendor or the ANSI C
116 * committee. It is well known that "compatible systems" are
117 * commonly created that have very different performance
118 * characteristics from the systems they are compatible with,
119 * especially those whose vendors make both the compiler and the
120 * system. Default definitions have been given, but its strongly
121 * recommended that users never use these definitions for any
122 * reason (they do *NOT* deliver any serious guarantee of
123 * improved performance -- not in this file, nor any vendor's
124 * stdint.h).
125 *
126 * 12) The following macros:
127 *
128 * PRINTF_INTMAX_MODIFIER
129 * PRINTF_INT64_MODIFIER
130 * PRINTF_INT32_MODIFIER
131 * PRINTF_INT16_MODIFIER
132 * PRINTF_LEAST64_MODIFIER
133 * PRINTF_LEAST32_MODIFIER
134 * PRINTF_LEAST16_MODIFIER
135 * PRINTF_INTPTR_MODIFIER
136 *
137 * are strings which have been defined as the modifiers required
138 * for the "d", "u" and "x" printf formats to correctly output
139 * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
140 * (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
141 * PRINTF_INTPTR_MODIFIER is not defined for some systems which
142 * provide their own stdint.h. PRINTF_INT64_MODIFIER is not
143 * defined if INT64_MAX is not defined. These are an extension
144 * beyond what C99 specifies must be in stdint.h.
145 *
146 * In addition, the following macros are defined:
147 *
148 * PRINTF_INTMAX_HEX_WIDTH
149 * PRINTF_INT64_HEX_WIDTH
150 * PRINTF_INT32_HEX_WIDTH
151 * PRINTF_INT16_HEX_WIDTH
152 * PRINTF_INT8_HEX_WIDTH
153 * PRINTF_INTMAX_DEC_WIDTH
154 * PRINTF_INT64_DEC_WIDTH
155 * PRINTF_INT32_DEC_WIDTH
156 * PRINTF_INT16_DEC_WIDTH
157 * PRINTF_INT8_DEC_WIDTH
158 *
159 * Which specifies the maximum number of characters required to
160 * print the number of that type in either hexadecimal or decimal.
161 * These are an extension beyond what C99 specifies must be in
162 * stdint.h.
163 *
164 * Compilers tested (all with 0 warnings at their highest respective
165 * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
166 * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
167 * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
168 *
169 * This file should be considered a work in progress. Suggestions for
170 * improvements, especially those which increase coverage are strongly
171 * encouraged.
