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. 172 * 173 * Acknowledgements 174 * 175 * The following people have made significant contributions to the 176 * development and testing of this file: 177 * 178 * Chris Howie 179 * John Steele Scott 180 * Dave Thorup 181 * 182 */ 183 184#include <stddef.h> 185#include <limits.h> 186#include <signal.h> 187 188/* 189 * For gcc with _STDINT_H, fill in the PRINTF_INT*_MODIFIER macros, and 190 * do nothing else.
