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. |
