- *
- ****************************************************************************
- *
- *  Version 0.1.16.0
- *
- *  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
- *  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
- *  single universal include file that works on as many platforms as
- *  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:
- *
- *    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 2s
- *       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.
- *
- *    5) In the current version, if your platform can't represent
- *       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
- *       PRINTF_UINT8_DEC_WIDTH
- *       PRINTF_UINTMAX_DEC_WIDTH
- *       PRINTF_UINT64_DEC_WIDTH
- *       PRINTF_UINT32_DEC_WIDTH
- *       PRINTF_UINT16_DEC_WIDTH
- *       PRINTF_UINT8_DEC_WIDTH
- *
- *       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
- *

-/* Illustrate the use of Z_BLOCK, inflatePrime(), and inflateSetDictionary()
-   for random access of a compressed file.  A file containing a zlib or gzip
-   stream is provided on the command line.  The compressed stream is decoded in
-   its entirety, and an index built with access points about every SPAN bytes
-   in the uncompressed output.  The compressed file is left open, and can then
-   be read randomly, having to decompress on the average SPAN/2 uncompressed
-   bytes before getting to the desired block of data.
-
-   An access point can be created at the start of any deflate block, by saving
-   the starting file offset and bit of that block, and the 32K bytes of
-   uncompressed data that precede that block.  Also the uncompressed offset of
-   that block is saved to provide a reference for locating a desired starting
-   point in the uncompressed stream.  deflate_index_build() works by
-   decompressing the input zlib or gzip stream a block at a time, and at the
-   end of each block deciding if enough uncompressed data has gone by to
-   justify the creation of a new access point.  If so, that point is saved in a
-   data structure that grows as needed to accommodate the points.
-
-   To use the index, an offset in the uncompressed data is provided, for which
-   the latest access point at or preceding that offset is located in the index.
-   The input file is positioned to the specified location in the index, and if
-   necessary the first few bits of the compressed data is read from the file.
-   inflate is initialized with those bits and the 32K of uncompressed data, and
-   the decompression then proceeds until the desired offset in the file is
-   reached.  Then the decompression continues to read the desired uncompressed
-   data from the file.
-
-   Another approach would be to generate the index on demand.  In that case,
-   requests for random access reads from the compressed data would try to use
-   the index, but if a read far enough past the end of the index is required,
-   then further index entries would be generated and added.
-
-   There is some fair bit of overhead to starting inflation for the random
-   access, mainly copying the 32K byte dictionary.  So if small pieces of the
-   file are being accessed, it would make sense to implement a cache to hold
-   some lookahead and avoid many calls to deflate_index_extract() for small
-   lengths.
-
-   Another way to build an index would be to use inflateCopy().  That would
-   not be constrained to have access points at block boundaries, but requires
-   more memory per access point, and also cannot be saved to file due to the
-   use of pointers in the state.  The approach here allows for storage of the
-   index in a file.
