* Version 0.1.11 | |
* | |
* The ANSI C standard committee, for the C99 standard, specified the | |
* inclusion of a new standard include file called stdint.h. 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. Suggestions for | |
* improvements, especially those which increase coverage are strongly | |
* encouraged. | |
* | |
