34  * Version 0.1.12
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.
