This is + * a very useful and long desired include file which contains several + * very precise definitions for integer scalar types that is + * critically important for making portable several classes of + * applications including cryptography, hashing, variable length + * integer libraries and so on. But for most developers its likely + * useful just for programming sanity. + * + * The problem is that most compiler vendors have decided not to + * implement the C99 standard, and the next C++ language standard + * (which has a lot more mindshare these days) will be a long time in + * coming and its unknown whether or not it will include stdint.h or + * how much adoption it will have. Either way, it will be a long time + * before all compilers come with a stdint.h and it also does nothing + * for the extremely large number of compilers available today which + * do not include this file, or anything comparable to it. + * + * So that's what this file is all about. Its an attempt to build a + * single universal include file that works on as many platforms as + * possible to deliver what stdint.h is supposed to. A few things + * that should be noted about this file: + * + * 1) It is not guaranteed to be portable and/or present an identical + * interface on all platforms. The extreme variability of the + * ANSI C standard makes this an impossibility right from the + * very get go. Its really only meant to be useful for the vast + * majority of platforms that possess the capability of + * implementing usefully and precisely defined, standard sized + * integer scalars. Systems which are not intrinsically 2s + * complement may produce invalid constants. + * + * 2) There is an unavoidable use of non-reserved symbols. + * + * 3) Other standard include files are invoked. + * + * 4) This file may come in conflict with future platforms that do + * include stdint.h. The hope is that one or the other can be + * used with no real difference. + * + * 5) In the current verison, if your platform can't represent + * int32_t, int16_t and int8_t, it just dumps out with a compiler + * error. + * + * 6) 64 bit integers may or may not be defined. Test for their + * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX. + * Note that this is different from the C99 specification which + * requires the existence of 64 bit support in the compiler. If + * this is not defined for your platform, yet it is capable of + * dealing with 64 bits then it is because this file has not yet + * been extended to cover all of your system's capabilities. + * + * 7) (u)intptr_t may or may not be defined. Test for its presence + * with the test: #ifdef PTRDIFF_MAX. If this is not defined + * for your platform, then it is because this file has not yet + * been extended to cover all of your system's capabilities, not + * because its optional. + * + * 8) The following might not been defined even if your platform is + * capable of defining it: + * + * WCHAR_MIN + * WCHAR_MAX + * (u)int64_t + * PTRDIFF_MIN + * PTRDIFF_MAX + * (u)intptr_t + * + * 9) The following have not been defined: + * + * WINT_MIN + * WINT_MAX + * + * 10) The criteria for defining (u)int_least(*)_t isn't clear, + * except for systems which don't have a type that precisely + * defined 8, 16, or 32 bit types (which this include file does + * not support anyways). Default definitions have been given. + * + * 11) The criteria for defining (u)int_fast(*)_t isn't something I + * would trust to any particular compiler vendor or the ANSI C + * committee. It is well known that "compatible systems" are + * commonly created that have very different performance + * characteristics from the systems they are compatible with, + * especially those whose vendors make both the compiler and the + * system. Default definitions have been given, but its strongly + * recommended that users never use these definitions for any + * reason (they do *NOT* deliver any serious guarantee of + * improved performance -- not in this file, nor any vendor's + * stdint.h). + * + * 12) The following macros: + * + * PRINTF_INTMAX_MODIFIER + * PRINTF_INT64_MODIFIER + * PRINTF_INT32_MODIFIER + * PRINTF_INT16_MODIFIER + * PRINTF_LEAST64_MODIFIER + * PRINTF_LEAST32_MODIFIER + * PRINTF_LEAST16_MODIFIER + * PRINTF_INTPTR_MODIFIER + * + * are strings which have been defined as the modifiers required + * for the "d", "u" and "x" printf formats to correctly output + * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t, + * (u)least32_t, (u)least16_t and (u)intptr_t types respectively. + * PRINTF_INTPTR_MODIFIER is not defined for some systems which + * provide their own stdint.h. PRINTF_INT64_MODIFIER is not + * defined if INT64_MAX is not defined. These are an extension + * beyond what C99 specifies must be in stdint.h. + * + * In addition, the following macros are defined: + * + * PRINTF_INTMAX_HEX_WIDTH + * PRINTF_INT64_HEX_WIDTH + * PRINTF_INT32_HEX_WIDTH + * PRINTF_INT16_HEX_WIDTH + * PRINTF_INT8_HEX_WIDTH + * PRINTF_INTMAX_DEC_WIDTH + * PRINTF_INT64_DEC_WIDTH + * PRINTF_INT32_DEC_WIDTH + * PRINTF_INT16_DEC_WIDTH + * PRINTF_INT8_DEC_WIDTH + * + * Which specifies the maximum number of characters required to + * print the number of that type in either hexadecimal or decimal. + * These are an extension beyond what C99 specifies must be in + * stdint.h. + * + * Compilers tested (all with 0 warnings at their highest respective + * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32 + * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio + * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3 + * + * This file should be considered a work in progress.
