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 several classes of applications portable * 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 some compiler vendors chose to ignore the C99 * standard and some older compilers have no opportunity to be updated. * Because of this situation, simply including stdint.h in your code * makes it unportable. * * So that's what this file is all about. It's 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. Even compilers * that already come with stdint.h can use this file instead without * any loss of functionality. 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 version, 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_UINT8_DEC_WIDTH * PRINTF_UINTMAX_DEC_WIDTH * PRINTF_UINT64_DEC_WIDTH * PRINTF_UINT32_DEC_WIDTH * PRINTF_UINT16_DEC_WIDTH * PRINTF_UINT8_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. Suggestions for * improvements, especially those which increase coverage are strongly * encouraged. * * Acknowledgements * * The following people have made significant contributions to the * development and testing of this file: * * Chris Howie * John Steele Scott * Dave Thorup * John Dill * Florian Wobbe * Christopher Sean Morrison * Mikkel Fahnoe Jorgensen * */ #include <stddef.h> #include <limits.h> #include <signal.h> /* * For gcc with _STDINT_H, fill in the PRINTF_INT*_MODIFIER macros, and * do nothing else.
