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 some compiler vendors chose to ignore the C99 46 * standard and some older compilers have no opportunity to be updated. 47 * Because of this situation, simply including stdint.h in your code 48 * makes it unportable. 49 * 50 * So that's what this file is all about. Its an attempt to build a 51 * single universal include file that works on as many platforms as 52 * possible to deliver what stdint.h is supposed to. Even compilers 53 * that already come with stdint.h can use this file instead without 54 * any loss of functionality. A few things that should be noted about 55 * this file: 56 * 57 * 1) It is not guaranteed to be portable and/or present an identical 58 * interface on all platforms. The extreme variability of the 59 * ANSI C standard makes this an impossibility right from the 60 * very get go. Its really only meant to be useful for the vast 61 * majority of platforms that possess the capability of 62 * implementing usefully and precisely defined, standard sized 63 * integer scalars. Systems which are not intrinsically 2s 64 * complement may produce invalid constants. 65 * 66 * 2) There is an unavoidable use of non-reserved symbols. 67 * 68 * 3) Other standard include files are invoked. 69 * 70 * 4) This file may come in conflict with future platforms that do 71 * include stdint.h. The hope is that one or the other can be 72 * used with no real difference. 73 * 74 * 5) In the current verison, if your platform can't represent 75 * int32_t, int16_t and int8_t, it just dumps out with a compiler 76 * error. 77 * 78 * 6) 64 bit integers may or may not be defined. Test for their 79 * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX. 80 * Note that this is different from the C99 specification which 81 * requires the existence of 64 bit support in the compiler. If 82 * this is not defined for your platform, yet it is capable of 83 * dealing with 64 bits then it is because this file has not yet 84 * been extended to cover all of your system's capabilities. 85 * 86 * 7) (u)intptr_t may or may not be defined. Test for its presence 87 * with the test: #ifdef PTRDIFF_MAX. If this is not defined 88 * for your platform, then it is because this file has not yet 89 * been extended to cover all of your system's capabilities, not 90 * because its optional. 91 * 92 * 8) The following might not been defined even if your platform is 93 * capable of defining it: 94 * 95 * WCHAR_MIN 96 * WCHAR_MAX 97 * (u)int64_t 98 * PTRDIFF_MIN 99 * PTRDIFF_MAX 100 * (u)intptr_t 101 * 102 * 9) The following have not been defined: 103 * 104 * WINT_MIN 105 * WINT_MAX 106 * 107 * 10) The criteria for defining (u)int_least(*)_t isn't clear, 108 * except for systems which don't have a type that precisely 109 * defined 8, 16, or 32 bit types (which this include file does 110 * not support anyways). Default definitions have been given. 111 * 112 * 11) The criteria for defining (u)int_fast(*)_t isn't something I 113 * would trust to any particular compiler vendor or the ANSI C 114 * committee. It is well known that "compatible systems" are 115 * commonly created that have very different performance 116 * characteristics from the systems they are compatible with, 117 * especially those whose vendors make both the compiler and the 118 * system. Default definitions have been given, but its strongly 119 * recommended that users never use these definitions for any 120 * reason (they do *NOT* deliver any serious guarantee of 121 * improved performance -- not in this file, nor any vendor's 122 * stdint.h). 123 * 124 * 12) The following macros: 125 * 126 * PRINTF_INTMAX_MODIFIER 127 * PRINTF_INT64_MODIFIER 128 * PRINTF_INT32_MODIFIER 129 * PRINTF_INT16_MODIFIER 130 * PRINTF_LEAST64_MODIFIER 131 * PRINTF_LEAST32_MODIFIER 132 * PRINTF_LEAST16_MODIFIER 133 * PRINTF_INTPTR_MODIFIER 134 * 135 * are strings which have been defined as the modifiers required 136 * for the "d", "u" and "x" printf formats to correctly output 137 * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t, 138 * (u)least32_t, (u)least16_t and (u)intptr_t types respectively. 139 * PRINTF_INTPTR_MODIFIER is not defined for some systems which 140 * provide their own stdint.h. PRINTF_INT64_MODIFIER is not 141 * defined if INT64_MAX is not defined. These are an extension 142 * beyond what C99 specifies must be in stdint.h. 143 * 144 * In addition, the following macros are defined: 145 * 146 * PRINTF_INTMAX_HEX_WIDTH 147 * PRINTF_INT64_HEX_WIDTH 148 * PRINTF_INT32_HEX_WIDTH 149 * PRINTF_INT16_HEX_WIDTH 150 * PRINTF_INT8_HEX_WIDTH 151 * PRINTF_INTMAX_DEC_WIDTH 152 * PRINTF_INT64_DEC_WIDTH 153 * PRINTF_INT32_DEC_WIDTH 154 * PRINTF_INT16_DEC_WIDTH 155 * PRINTF_UINT8_DEC_WIDTH 156 * PRINTF_UINTMAX_DEC_WIDTH 157 * PRINTF_UINT64_DEC_WIDTH 158 * PRINTF_UINT32_DEC_WIDTH 159 * PRINTF_UINT16_DEC_WIDTH 160 * PRINTF_UINT8_DEC_WIDTH 161 * 162 * Which specifies the maximum number of characters required to 163 * print the number of that type in either hexadecimal or decimal. 164 * These are an extension beyond what C99 specifies must be in 165 * stdint.h. 166 * 167 * Compilers tested (all with 0 warnings at their highest respective 168 * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32 169 * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio 170 * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3 171 * 172 * This file should be considered a work in progress. Suggestions for 173 * improvements, especially those which increase coverage are strongly 174 * encouraged. 175 * 176 * Acknowledgements 177 * 178 * The following people have made significant contributions to the 179 * development and testing of this file: 180 * 181 * Chris Howie 182 * John Steele Scott 183 * Dave Thorup 184 * John Dill 185 * Florian Wobbe 186 * Christopher Sean Morrison 187 * Mikkel Fahnoe Jorgensen 188 * 189 */ 190 191 #include <stddef.h> 192 #include <limits.h> 193 #include <signal.h> 194 195 /* 196 * For gcc with _STDINT_H, fill in the PRINTF_INT*_MODIFIER macros, and 197 * do nothing else.
