00034  *  Version 0.1.11
00035  *
00036  *  The ANSI C standard committee, for the C99 standard, specified the
00037  *  inclusion of a new standard include file called stdint.h.  This is
00038  *  a very useful and long desired include file which contains several
00039  *  very precise definitions for integer scalar types that is
00040  *  critically important for making portable several classes of
00041  *  applications including cryptography, hashing, variable length
00042  *  integer libraries and so on.  But for most developers its likely
00043  *  useful just for programming sanity.
00044  *
00045  *  The problem is that most compiler vendors have decided not to
00046  *  implement the C99 standard, and the next C++ language standard
00047  *  (which has a lot more mindshare these days) will be a long time in
00048  *  coming and its unknown whether or not it will include stdint.h or
00049  *  how much adoption it will have.  Either way, it will be a long time
00050  *  before all compilers come with a stdint.h and it also does nothing
00051  *  for the extremely large number of compilers available today which
00052  *  do not include this file, or anything comparable to it.
00053  *
00054  *  So that's what this file is all about.  Its an attempt to build a
00055  *  single universal include file that works on as many platforms as
00056  *  possible to deliver what stdint.h is supposed to.  A few things
00057  *  that should be noted about this file:
00058  *
00059  *    1) It is not guaranteed to be portable and/or present an identical
00060  *       interface on all platforms.  The extreme variability of the
00061  *       ANSI C standard makes this an impossibility right from the
00062  *       very get go. Its really only meant to be useful for the vast
00063  *       majority of platforms that possess the capability of
00064  *       implementing usefully and precisely defined, standard sized
00065  *       integer scalars.  Systems which are not intrinsically 2s
00066  *       complement may produce invalid constants.
00067  *
00068  *    2) There is an unavoidable use of non-reserved symbols.
00069  *
00070  *    3) Other standard include files are invoked.
00071  *
00072  *    4) This file may come in conflict with future platforms that do
00073  *       include stdint.h.  The hope is that one or the other can be
00074  *       used with no real difference.
00075  *
00076  *    5) In the current verison, if your platform can't represent
00077  *       int32_t, int16_t and int8_t, it just dumps out with a compiler
00078  *       error.
00079  *
00080  *    6) 64 bit integers may or may not be defined.  Test for their
00081  *       presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
00082  *       Note that this is different from the C99 specification which
00083  *       requires the existence of 64 bit support in the compiler.  If
00084  *       this is not defined for your platform, yet it is capable of
00085  *       dealing with 64 bits then it is because this file has not yet
00086  *       been extended to cover all of your system's capabilities.
00087  *
00088  *    7) (u)intptr_t may or may not be defined.  Test for its presence
00089  *       with the test: #ifdef PTRDIFF_MAX.  If this is not defined
00090  *       for your platform, then it is because this file has not yet
00091  *       been extended to cover all of your system's capabilities, not
00092  *       because its optional.
00093  *
00094  *    8) The following might not been defined even if your platform is
00095  *       capable of defining it:
00096  *
00097  *       WCHAR_MIN
00098  *       WCHAR_MAX
00099  *       (u)int64_t
00100  *       PTRDIFF_MIN
00101  *       PTRDIFF_MAX
00102  *       (u)intptr_t
00103  *
00104  *    9) The following have not been defined:
00105  *
00106  *       WINT_MIN
00107  *       WINT_MAX
00108  *
00109  *   10) The criteria for defining (u)int_least(*)_t isn't clear,
00110  *       except for systems which don't have a type that precisely
00111  *       defined 8, 16, or 32 bit types (which this include file does
00112  *       not support anyways). Default definitions have been given.
00113  *
00114  *   11) The criteria for defining (u)int_fast(*)_t isn't something I
00115  *       would trust to any particular compiler vendor or the ANSI C
00116  *       committee.  It is well known that "compatible systems" are
00117  *       commonly created that have very different performance
00118  *       characteristics from the systems they are compatible with,
00119  *       especially those whose vendors make both the compiler and the
00120  *       system.  Default definitions have been given, but its strongly
00121  *       recommended that users never use these definitions for any
00122  *       reason (they do *NOT* deliver any serious guarantee of
00123  *       improved performance -- not in this file, nor any vendor's
00124  *       stdint.h).
00125  *
00126  *   12) The following macros:
00127  *
00128  *       PRINTF_INTMAX_MODIFIER
00129  *       PRINTF_INT64_MODIFIER
00130  *       PRINTF_INT32_MODIFIER
00131  *       PRINTF_INT16_MODIFIER
00132  *       PRINTF_LEAST64_MODIFIER
00133  *       PRINTF_LEAST32_MODIFIER
00134  *       PRINTF_LEAST16_MODIFIER
00135  *       PRINTF_INTPTR_MODIFIER
00136  *
00137  *       are strings which have been defined as the modifiers required
00138  *       for the "d", "u" and "x" printf formats to correctly output
00139  *       (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
00140  *       (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
00141  *       PRINTF_INTPTR_MODIFIER is not defined for some systems which
00142  *       provide their own stdint.h.  PRINTF_INT64_MODIFIER is not
00143  *       defined if INT64_MAX is not defined.  These are an extension
00144  *       beyond what C99 specifies must be in stdint.h.
00145  *
00146  *       In addition, the following macros are defined:
00147  *
00148  *       PRINTF_INTMAX_HEX_WIDTH
00149  *       PRINTF_INT64_HEX_WIDTH
00150  *       PRINTF_INT32_HEX_WIDTH
00151  *       PRINTF_INT16_HEX_WIDTH
00152  *       PRINTF_INT8_HEX_WIDTH
00153  *       PRINTF_INTMAX_DEC_WIDTH
00154  *       PRINTF_INT64_DEC_WIDTH
00155  *       PRINTF_INT32_DEC_WIDTH
00156  *       PRINTF_INT16_DEC_WIDTH
00157  *       PRINTF_INT8_DEC_WIDTH
00158  *
00159  *       Which specifies the maximum number of characters required to
00160  *       print the number of that type in either hexadecimal or decimal.
00161  *       These are an extension beyond what C99 specifies must be in
00162  *       stdint.h.
00163  *
00164  *  Compilers tested (all with 0 warnings at their highest respective
00165  *  settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
00166  *  bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
00167  *  .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
00168  *
00169  *  This file should be considered a work in progress.  Suggestions for
00170  *  improvements, especially those which increase coverage are strongly
00171  *  encouraged.
