2018-11-03 18:09:13 +01:00
* Version 0.1 .16 .0
2008-04-03 15:40:36 +02:00
*
* 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
2018-11-03 18:09:13 +01:00
* 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
2008-04-03 15:40:36 +02:00
* single universal include file that works on as many platforms as
2018-11-03 18:09:13 +01:00
* 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 :
2008-04-03 15:40:36 +02:00
*
* 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 2 s
* 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 .
*
2018-11-03 18:09:13 +01:00
* 5 ) In the current version , if your platform can ' t represent
2008-04-03 15:40:36 +02:00
* 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
2018-11-03 18:09:13 +01:00
* PRINTF_UINT8_DEC_WIDTH
* PRINTF_UINTMAX_DEC_WIDTH
* PRINTF_UINT64_DEC_WIDTH
* PRINTF_UINT32_DEC_WIDTH
* PRINTF_UINT16_DEC_WIDTH
* PRINTF_UINT8_DEC_WIDTH
2008-04-03 15:40:36 +02:00
*
* 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 .
