|
* Version 0.1.16.0 |
|
* |
|
* 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 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. |
