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. |
