- * Version 0.1.12 |
|
| 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. |

| 34 |
+ * Version 0.1.12 |
|
| 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 |
