34  *  Version 0.1.11
35  *
36  *  The ANSI C standard committee, for the C99 standard, specified the
37  *  inclusion of a new standard include file called stdint.h.  This is
38  *  a very useful and long desired include file which contains several
39  *  very precise definitions for integer scalar types that is
40  *  critically important for making portable several classes of
41  *  applications including cryptography, hashing, variable length
42  *  integer libraries and so on.  But for most developers its likely
43  *  useful just for programming sanity.
44  *
45  *  The problem is that most compiler vendors have decided not to
46  *  implement the C99 standard, and the next C++ language standard
47  *  (which has a lot more mindshare these days) will be a long time in
48  *  coming and its unknown whether or not it will include stdint.h or
49  *  how much adoption it will have.  Either way, it will be a long time
50  *  before all compilers come with a stdint.h and it also does nothing
51  *  for the extremely large number of compilers available today which
52  *  do not include this file, or anything comparable to it.
53  *
54  *  So that's what this file is all about.  Its an attempt to build a
55  *  single universal include file that works on as many platforms as
56  *  possible to deliver what stdint.h is supposed to.  A few things
57  *  that should be noted about this file:
58  *
59  *    1) It is not guaranteed to be portable and/or present an identical
60  *       interface on all platforms.  The extreme variability of the
61  *       ANSI C standard makes this an impossibility right from the
62  *       very get go. Its really only meant to be useful for the vast
63  *       majority of platforms that possess the capability of
64  *       implementing usefully and precisely defined, standard sized
65  *       integer scalars.  Systems which are not intrinsically 2s
66  *       complement may produce invalid constants.
67  *
68  *    2) There is an unavoidable use of non-reserved symbols.
69  *
70  *    3) Other standard include files are invoked.
71  *
72  *    4) This file may come in conflict with future platforms that do
73  *       include stdint.h.  The hope is that one or the other can be
74  *       used with no real difference.
75  *
76  *    5) In the current verison, if your platform can't represent
77  *       int32_t, int16_t and int8_t, it just dumps out with a compiler
78  *       error.
79  *
80  *    6) 64 bit integers may or may not be defined.  Test for their
81  *       presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX.
82  *       Note that this is different from the C99 specification which
83  *       requires the existence of 64 bit support in the compiler.  If
84  *       this is not defined for your platform, yet it is capable of
85  *       dealing with 64 bits then it is because this file has not yet
86  *       been extended to cover all of your system's capabilities.
87  *
88  *    7) (u)intptr_t may or may not be defined.  Test for its presence
89  *       with the test: #ifdef PTRDIFF_MAX.  If this is not defined
90  *       for your platform, then it is because this file has not yet
91  *       been extended to cover all of your system's capabilities, not
92  *       because its optional.
93  *
94  *    8) The following might not been defined even if your platform is
95  *       capable of defining it:
96  *
97  *       WCHAR_MIN
98  *       WCHAR_MAX
99  *       (u)int64_t
100  *       PTRDIFF_MIN
101  *       PTRDIFF_MAX
102  *       (u)intptr_t
103  *
104  *    9) The following have not been defined:
105  *
106  *       WINT_MIN
107  *       WINT_MAX
108  *
109  *   10) The criteria for defining (u)int_least(*)_t isn't clear,
110  *       except for systems which don't have a type that precisely
111  *       defined 8, 16, or 32 bit types (which this include file does
112  *       not support anyways). Default definitions have been given.
113  *
114  *   11) The criteria for defining (u)int_fast(*)_t isn't something I
115  *       would trust to any particular compiler vendor or the ANSI C
116  *       committee.  It is well known that "compatible systems" are
117  *       commonly created that have very different performance
118  *       characteristics from the systems they are compatible with,
119  *       especially those whose vendors make both the compiler and the
120  *       system.  Default definitions have been given, but its strongly
121  *       recommended that users never use these definitions for any
122  *       reason (they do *NOT* deliver any serious guarantee of
123  *       improved performance -- not in this file, nor any vendor's
124  *       stdint.h).
125  *
126  *   12) The following macros:
127  *
128  *       PRINTF_INTMAX_MODIFIER
129  *       PRINTF_INT64_MODIFIER
130  *       PRINTF_INT32_MODIFIER
131  *       PRINTF_INT16_MODIFIER
132  *       PRINTF_LEAST64_MODIFIER
133  *       PRINTF_LEAST32_MODIFIER
134  *       PRINTF_LEAST16_MODIFIER
135  *       PRINTF_INTPTR_MODIFIER
136  *
137  *       are strings which have been defined as the modifiers required
138  *       for the "d", "u" and "x" printf formats to correctly output
139  *       (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t,
140  *       (u)least32_t, (u)least16_t and (u)intptr_t types respectively.
141  *       PRINTF_INTPTR_MODIFIER is not defined for some systems which
142  *       provide their own stdint.h.  PRINTF_INT64_MODIFIER is not
143  *       defined if INT64_MAX is not defined.  These are an extension
144  *       beyond what C99 specifies must be in stdint.h.
145  *
146  *       In addition, the following macros are defined:
147  *
148  *       PRINTF_INTMAX_HEX_WIDTH
149  *       PRINTF_INT64_HEX_WIDTH
150  *       PRINTF_INT32_HEX_WIDTH
151  *       PRINTF_INT16_HEX_WIDTH
152  *       PRINTF_INT8_HEX_WIDTH
153  *       PRINTF_INTMAX_DEC_WIDTH
154  *       PRINTF_INT64_DEC_WIDTH
155  *       PRINTF_INT32_DEC_WIDTH
156  *       PRINTF_INT16_DEC_WIDTH
157  *       PRINTF_INT8_DEC_WIDTH
158  *
159  *       Which specifies the maximum number of characters required to
160  *       print the number of that type in either hexadecimal or decimal.
161  *       These are an extension beyond what C99 specifies must be in
162  *       stdint.h.
163  *
164  *  Compilers tested (all with 0 warnings at their highest respective
165  *  settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32
166  *  bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio
167  *  .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3
168  *
169  *  This file should be considered a work in progress.  Suggestions for
170  *  improvements, especially those which increase coverage are strongly
171  *  encouraged.
