---|
| 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. |
