  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.
