|
|
* Version 0.1.12
|
|
*
|
|
* 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.
