-bzip2 should compile without problems on the vast majority of -platforms. Using the supplied Makefile, I've built and tested it -myself for x86-linux and amd64-linux. With makefile.msc, Visual C++ -6.0 and nmake, you can build a native Win32 version too. Large file -support seems to work correctly on at least on amd64-linux. - -When I say "large file" I mean a file of size 2,147,483,648 (2^31) -bytes or above. Many older OSs can't handle files above this size, -but many newer ones can. Large files are pretty huge -- most files -you'll encounter are not Large Files. - -Early versions of bzip2 (0.1, 0.9.0, 0.9.5) compiled on a wide variety -of platforms without difficulty, and I hope this version will continue -in that tradition. However, in order to support large files, I've had -to include the define -D_FILE_OFFSET_BITS=64 in the Makefile. This -can cause problems. - -The technique of adding -D_FILE_OFFSET_BITS=64 to get large file -support is, as far as I know, the Recommended Way to get correct large -file support. For more details, see the Large File Support -Specification, published by the Large File Summit, at - - http://ftp.sas.com/standards/large.file - -As a general comment, if you get compilation errors which you think -are related to large file support, try removing the above define from -the Makefile, ie, delete the line - - BIGFILES=-D_FILE_OFFSET_BITS=64 - -from the Makefile, and do 'make clean ; make'. This will give you a -version of bzip2 without large file support, which, for most -applications, is probably not a problem. - -Alternatively, try some of the platform-specific hints listed below. - -You can use the spewG.c program to generate huge files to test bzip2's -large file support, if you are feeling paranoid. Be aware though that -any compilation problems which affect bzip2 will also affect spewG.c, -alas. - -AIX: I have reports that for large file support, you need to specify --D_LARGE_FILES rather than -D_FILE_OFFSET_BITS=64.

-DESCRIPTION
-
-bzip2 compresses files
-using the Burrows-Wheeler block sorting text compression
-algorithm, and Huffman coding.  Compression is generally
-considerably better than that achieved by more conventional
-LZ77/LZ78-based compressors, and approaches the performance of
-the PPM family of statistical compressors.
-
-The command-line options are deliberately very similar to
-those of GNU gzip, but they are
-not identical.
-
-bzip2 expects a list of
-file names to accompany the command-line flags.  Each file is
-replaced by a compressed version of itself, with the name
-original_name.bz2.  Each
-compressed file has the same modification date, permissions, and,
-when possible, ownership as the corresponding original, so that
-these properties can be correctly restored at decompression time.
-File name handling is naive in the sense that there is no
-mechanism for preserving original file names, permissions,
-ownerships or dates in filesystems which lack these concepts, or
-have serious file name length restrictions, such as
-MS-DOS.
-
-bzip2 and
-bunzip2 will by default not
-overwrite existing files.  If you want this to happen, specify
-the -f flag.
-
-If no file names are specified,
-bzip2 compresses from standard
-input to standard output.  In this case,
-bzip2 will decline to write
-compressed output to a terminal, as this would be entirely
-incomprehensible and therefore pointless.
-
-bunzip2 (or
-bzip2 -d) decompresses all
-specified files.  Files which were not created by
-bzip2 will be detected and
-ignored, and a warning issued.
-bzip2 attempts to guess the
-filename for the decompressed file from that of the compressed
-file as follows:
-
-
-
- filename.bz2 
-  becomes
-  filename
-
- filename.bz 
-  becomes
-  filename
-
- filename.tbz2
-  becomes
-  filename.tar
-
- filename.tbz 
-  becomes
-  filename.tar
-
- anyothername 
-  becomes
-  anyothername.out
-
-
-
-If the file does not end in one of the recognised endings,
-.bz2,
-.bz,
-.tbz2 or
-.tbz,
-bzip2 complains that it cannot
-guess the name of the original file, and uses the original name
-with .out appended.
-
-As with compression, supplying no filenames causes
-decompression from standard input to standard output.
-
-bunzip2 will correctly
-decompress a file which is the concatenation of two or more
-compressed files.  The result is the concatenation of the
-corresponding uncompressed files.  Integrity testing
-(-t) of concatenated compressed
-files is also supported.
-
-You can also compress or decompress files to the standard
-output by giving the -c flag.
-Multiple files may be compressed and decompressed like this.  The
-resulting outputs are fed sequentially to stdout.  Compression of
-multiple files in this manner generates a stream containing
-multiple compressed file representations.  Such a stream can be
-decompressed correctly only by
-bzip2 version 0.9.0 or later.
-Earlier versions of bzip2 will
-stop after decompressing the first file in the stream.
-
-bzcat (or
-bzip2 -dc) decompresses all
-specified files to the standard output.
-
-bzip2 will read arguments
-from the environment variables
-BZIP2 and
-BZIP, in that order, and will
-process them before any arguments read from the command line.
-This gives a convenient way to supply default arguments.
-
-Compression is always performed, even if the compressed
-file is slightly larger than the original.  Files of less than
-about one hundred bytes tend to get larger, since the compression
-mechanism has a constant overhead in the region of 50 bytes.
-Random data (including the output of most file compressors) is
-coded at about 8.05 bits per byte, giving an expansion of around
-0.5%.
-
-As a self-check for your protection,
-bzip2 uses 32-bit CRCs to make
-sure that the decompressed version of a file is identical to the
-original.  This guards against corruption of the compressed data,
-and against undetected bugs in
-bzip2 (hopefully very unlikely).
-The chances of data corruption going undetected is microscopic,
-about one chance in four billion for each file processed.  Be
-aware, though, that the check occurs upon decompression, so it
-can only tell you that something is wrong.  It can't help you
-recover the original uncompressed data.  You can use
-bzip2recover to try to recover
-data from damaged files.
-
-Return values: 0 for a normal exit, 1 for environmental
-problems (file not found, invalid flags, I/O errors, etc.), 2
-to indicate a corrupt compressed file, 3 for an internal
-consistency error (eg, bug) which caused
-bzip2 to panic.
-
-
-
-
-
-OPTIONS
-
-
-
- 
- -c --stdout
- Compress or decompress to standard
-  output.
- 
-
- 
- -d --decompress
- Force decompression.
-  bzip2,
-  bunzip2 and
-  bzcat are really the same
-  program, and the decision about what actions to take is done on
-  the basis of which name is used.  This flag overrides that
-  mechanism, and forces bzip2 to decompress.
- 
-
- 
- -z --compress
- The complement to
-  -d: forces compression,
-  regardless of the invokation name.
- 
-
- 
- -t --test
- Check integrity of the specified file(s), but
-  don't decompress them.  This really performs a trial
-  decompression and throws away the result.
- 
-
- 
- -f --force
- Force overwrite of output files.  Normally,
-  bzip2 will not overwrite
-  existing output files.  Also forces
-  bzip2 to break hard links to
-  files, which it otherwise wouldn't do.
-  bzip2 normally declines
-  to decompress files which don't have the correct magic header
-  bytes. If forced (-f),
-  however, it will pass such files through unmodified. This is
-  how GNU gzip behaves.
- 
- 
-
- 
- -k --keep
- Keep (don't delete) input files during
-  compression or decompression.
- 
-
- 
- -s --small
- Reduce memory usage, for compression,
-  decompression and testing.  Files are decompressed and tested
-  using a modified algorithm which only requires 2.5 bytes per
-  block byte.  This means any file can be decompressed in 2300k
-  of memory, albeit at about half the normal speed.
-  During compression, -s
-  selects a block size of 200k, which limits memory use to around
-  the same figure, at the expense of your compression ratio.  In
-  short, if your machine is low on memory (8 megabytes or less),
-  use -s for everything.  See
-   below.
- 
-
- 
- -q --quiet
- Suppress non-essential warning messages.
-  Messages pertaining to I/O errors and other critical events
-  will not be suppressed.
- 
-
- 
- -v --verbose
- Verbose mode -- show the compression ratio for
-  each file processed.  Further
-  -v's increase the verbosity
-  level, spewing out lots of information which is primarily of
-  interest for diagnostic purposes.
- 
-
- 
- -L --license -V --version
- Display the software version, license terms and
-  conditions.
- 
-
- 
- -1 (or
- --fast) to
- -9 (or
- -best)
- Set the block size to 100 k, 200 k ...  900 k
-  when compressing.  Has no effect when decompressing.  See  below.  The
-  --fast and
-  --best aliases are primarily
-  for GNU gzip compatibility.
-  In particular, --fast doesn't
-  make things significantly faster.  And
-  --best merely selects the
-  default behaviour.
- 
-
- 
- --
- Treats all subsequent arguments as file names,
-  even if they start with a dash.  This is so you can handle
-  files with names beginning with a dash, for example:
-  bzip2 --
-  -myfilename.
- 
-
- 
- --repetitive-fast
- --repetitive-best
- These flags are redundant in versions 0.9.5 and
-  above.  They provided some coarse control over the behaviour of
-  the sorting algorithm in earlier versions, which was sometimes
-  useful.  0.9.5 and above have an improved algorithm which
-  renders these flags irrelevant.
- 
-
-
-
-
-
-
-
-MEMORY MANAGEMENT
-
-bzip2 compresses large
-files in blocks.  The block size affects both the compression
-ratio achieved, and the amount of memory needed for compression
-and decompression.  The flags -1
-through -9 specify the block
-size to be 100,000 bytes through 900,000 bytes (the default)
-respectively.  At decompression time, the block size used for
-compression is read from the header of the compressed file, and
-bunzip2 then allocates itself
-just enough memory to decompress the file.  Since block sizes are
-stored in compressed files, it follows that the flags
--1 to
--9 are irrelevant to and so
-ignored during decompression.
-
-Compression and decompression requirements, in bytes, can be
-estimated as:
-
-Compression:   400k + ( 8 x block size )
-
-Decompression: 100k + ( 4 x block size ), or
-               100k + ( 2.5 x block size )
-
-
-Larger block sizes give rapidly diminishing marginal
-returns.  Most of the compression comes from the first two or
-three hundred k of block size, a fact worth bearing in mind when
-using bzip2 on small machines.
-It is also important to appreciate that the decompression memory
-requirement is set at compression time by the choice of block
-size.
-
-For files compressed with the default 900k block size,
-bunzip2 will require about 3700
-kbytes to decompress.  To support decompression of any file on a
-4 megabyte machine, bunzip2 has
-an option to decompress using approximately half this amount of
-memory, about 2300 kbytes.  Decompression speed is also halved,
-so you should use this option only where necessary.  The relevant
-flag is -s.
-
-In general, try and use the largest block size memory
-constraints allow, since that maximises the compression achieved.
-Compression and decompression speed are virtually unaffected by
-block size.
-
-Another significant point applies to files which fit in a
-single block -- that means most files you'd encounter using a
-large block size.  The amount of real memory touched is
-proportional to the size of the file, since the file is smaller
-than a block.  For example, compressing a file 20,000 bytes long
-with the flag -9 will cause the
-compressor to allocate around 7600k of memory, but only touch
-400k + 20000 * 8 = 560 kbytes of it.  Similarly, the decompressor
-will allocate 3700k but only touch 100k + 20000 * 4 = 180
-kbytes.
-
-Here is a table which summarises the maximum memory usage
-for different block sizes.  Also recorded is the total compressed
-size for 14 files of the Calgary Text Compression Corpus
-totalling 3,141,622 bytes.  This column gives some feel for how
-compression varies with block size.  These figures tend to
-understate the advantage of larger block sizes for larger files,
-since the Corpus is dominated by smaller files.

-
-RECOVERING DATA FROM DAMAGED FILES
-
-bzip2 compresses files in
-blocks, usually 900kbytes long.  Each block is handled
-independently.  If a media or transmission error causes a
-multi-block .bz2 file to become
-damaged, it may be possible to recover data from the undamaged
-blocks in the file.
-
-The compressed representation of each block is delimited by
-a 48-bit pattern, which makes it possible to find the block
-boundaries with reasonable certainty.  Each block also carries
-its own 32-bit CRC, so damaged blocks can be distinguished from
-undamaged ones.
-
-bzip2recover is a simple
-program whose purpose is to search for blocks in
-.bz2 files, and write each block
-out into its own .bz2 file.  You
-can then use bzip2 -t to test
-the integrity of the resulting files, and decompress those which
-are undamaged.
-
-bzip2recover takes a
-single argument, the name of the damaged file, and writes a
-number of files rec0001file.bz2,
-rec0002file.bz2, etc, containing
-the extracted blocks.  The output filenames are designed so that
-the use of wildcards in subsequent processing -- for example,
-bzip2 -dc rec*file.bz2 >
-recovered_data -- lists the files in the correct
-order.
-
-bzip2recover should be of
-most use dealing with large .bz2
-files, as these will contain many blocks.  It is clearly futile
-to use it on damaged single-block files, since a damaged block
-cannot be recovered.  If you wish to minimise any potential data
-loss through media or transmission errors, you might consider
-compressing with a smaller block size.
-
-

-PERFORMANCE NOTES
-
-The sorting phase of compression gathers together similar
-strings in the file.  Because of this, files containing very long
-runs of repeated symbols, like "aabaabaabaab ..."  (repeated
-several hundred times) may compress more slowly than normal.
-Versions 0.9.5 and above fare much better than previous versions
-in this respect.  The ratio between worst-case and average-case
-compression time is in the region of 10:1.  For previous
-versions, this figure was more like 100:1.  You can use the
--vvvv option to monitor progress
-in great detail, if you want.
-
-Decompression speed is unaffected by these
-phenomena.
-
-bzip2 usually allocates
-several megabytes of memory to operate in, and then charges all
-over it in a fairly random fashion.  This means that performance,
-both for compressing and decompressing, is largely determined by
-the speed at which your machine can service cache misses.
-Because of this, small changes to the code to reduce the miss
-rate have been observed to give disproportionately large
-performance improvements.  I imagine
-bzip2 will perform best on
-machines with very large caches.
-

-
-
-CAVEATS
-
-I/O error messages are not as helpful as they could be.
-bzip2 tries hard to detect I/O
-errors and exit cleanly, but the details of what the problem is
-sometimes seem rather misleading.
-
-This manual page pertains to version &bz-version; of
-bzip2.  Compressed data created by
-this version is entirely forwards and backwards compatible with the
-previous public releases, versions 0.1pl2, 0.9.0 and 0.9.5, 1.0.0,
-1.0.1, 1.0.2 and 1.0.3, but with the following exception: 0.9.0 and
-above can correctly decompress multiple concatenated compressed files.
-0.1pl2 cannot do this; it will stop after decompressing just the first
-file in the stream.
-
-bzip2recover versions
-prior to 1.0.2 used 32-bit integers to represent bit positions in
-compressed files, so it could not handle compressed files more
-than 512 megabytes long.  Versions 1.0.2 and above use 64-bit ints
-on some platforms which support them (GNU supported targets, and
-Windows). To establish whether or not
-bzip2recover was built with such
-a limitation, run it without arguments. In any event you can
-build yourself an unlimited version if you can recompile it with
-MaybeUInt64 set to be an
-unsigned 64-bit integer.

-The ideas embodied in
-bzip2 are due to (at least) the
-following people: Michael Burrows and David Wheeler (for the
-block sorting transformation), David Wheeler (again, for the
-Huffman coder), Peter Fenwick (for the structured coding model in
-the original bzip, and many
-refinements), and Alistair Moffat, Radford Neal and Ian Witten
-(for the arithmetic coder in the original
-bzip).  I am much indebted for
-their help, support and advice.  See the manual in the source
-distribution for pointers to sources of documentation.  Christian
-von Roques encouraged me to look for faster sorting algorithms,
-so as to speed up compression.  Bela Lubkin encouraged me to
-improve the worst-case compression performance.  
-Donna Robinson XMLised the documentation.
-Many people sent
-patches, helped with portability problems, lent machines, gave
-advice and were generally helpful.

-Programming with <computeroutput>libbzip2</computeroutput>
-
-
-This chapter describes the programming interface to
-libbzip2.
-
-For general background information, particularly about
-memory use and performance aspects, you'd be well advised to read
- as well.
-
-
-
-Top-level structure
-
-libbzip2 is a flexible
-library for compressing and decompressing data in the
-bzip2 data format.  Although
-packaged as a single entity, it helps to regard the library as
-three separate parts: the low level interface, and the high level
-interface, and some utility functions.
-
-The structure of
-libbzip2's interfaces is similar
-to that of Jean-loup Gailly's and Mark Adler's excellent
-zlib library.
-
-All externally visible symbols have names beginning
-BZ2_.  This is new in version
-1.0.  The intention is to minimise pollution of the namespaces of
-library clients.
-
-To use any part of the library, you need to
-#include <bzlib.h>
-into your sources.
-
-
-
-
-Low-level summary
-
-This interface provides services for compressing and
-decompressing data in memory.  There's no provision for dealing
-with files, streams or any other I/O mechanisms, just straight
-memory-to-memory work.  In fact, this part of the library can be
-compiled without inclusion of
-stdio.h, which may be helpful
-for embedded applications.
-
-The low-level part of the library has no global variables
-and is therefore thread-safe.
-
-Six routines make up the low level interface:
-BZ2_bzCompressInit,
-BZ2_bzCompress, and
-BZ2_bzCompressEnd for
-compression, and a corresponding trio
-BZ2_bzDecompressInit,
-BZ2_bzDecompress and
-BZ2_bzDecompressEnd for
-decompression.  The *Init
-functions allocate memory for compression/decompression and do
-other initialisations, whilst the
-*End functions close down
-operations and release memory.
-
-The real work is done by
-BZ2_bzCompress and
-BZ2_bzDecompress.  These
-compress and decompress data from a user-supplied input buffer to
-a user-supplied output buffer.  These buffers can be any size;
-arbitrary quantities of data are handled by making repeated calls
-to these functions.  This is a flexible mechanism allowing a
-consumer-pull style of activity, or producer-push, or a mixture
-of both.
-
-
-
-
-
-High-level summary
-
-This interface provides some handy wrappers around the
-low-level interface to facilitate reading and writing
-bzip2 format files
-(.bz2 files).  The routines
-provide hooks to facilitate reading files in which the
-bzip2 data stream is embedded
-within some larger-scale file structure, or where there are
-multiple bzip2 data streams
-concatenated end-to-end.
-
-For reading files,
-BZ2_bzReadOpen,
-BZ2_bzRead,
-BZ2_bzReadClose and 
-BZ2_bzReadGetUnused are
-supplied.  For writing files,
-BZ2_bzWriteOpen,
-BZ2_bzWrite and
-BZ2_bzWriteFinish are
-available.
-
-As with the low-level library, no global variables are used
-so the library is per se thread-safe.  However, if I/O errors
-occur whilst reading or writing the underlying compressed files,
-you may have to consult errno to
-determine the cause of the error.  In that case, you'd need a C
-library which correctly supports
-errno in a multithreaded
-environment.
-
-To make the library a little simpler and more portable,
-BZ2_bzReadOpen and
-BZ2_bzWriteOpen require you to
-pass them file handles (FILE*s)
-which have previously been opened for reading or writing
-respectively.  That avoids portability problems associated with
-file operations and file attributes, whilst not being much of an
-imposition on the programmer.
-
-
-
-
-
-Utility functions summary
-
-For very simple needs,
-BZ2_bzBuffToBuffCompress and
-BZ2_bzBuffToBuffDecompress are
-provided.  These compress data in memory from one buffer to
-another buffer in a single function call.  You should assess
-whether these functions fulfill your memory-to-memory
-compression/decompression requirements before investing effort in
-understanding the more general but more complex low-level
-interface.
-
-Yoshioka Tsuneo
-(tsuneo@rr.iij4u.or.jp) has
-contributed some functions to give better
-zlib compatibility.  These
-functions are BZ2_bzopen,
-BZ2_bzread,
-BZ2_bzwrite,
-BZ2_bzflush,
-BZ2_bzclose,
-BZ2_bzerror and
-BZ2_bzlibVersion.  You may find
-these functions more convenient for simple file reading and
-writing, than those in the high-level interface.  These functions
-are not (yet) officially part of the library, and are minimally
-documented here.  If they break, you get to keep all the pieces.
-I hope to document them properly when time permits.
-
-Yoshioka also contributed modifications to allow the
-library to be built as a Windows DLL.

-Error handling
-
-The library is designed to recover cleanly in all
-situations, including the worst-case situation of decompressing
-random data.  I'm not 100% sure that it can always do this, so
-you might want to add a signal handler to catch segmentation
-violations during decompression if you are feeling especially
-paranoid.  I would be interested in hearing more about the
-robustness of the library to corrupted compressed data.
-
-Version 1.0.3 more robust in this respect than any
-previous version.  Investigations with Valgrind (a tool for detecting
-problems with memory management) indicate
-that, at least for the few files I tested, all single-bit errors
-in the decompressed data are caught properly, with no
-segmentation faults, no uses of uninitialised data, no out of
-range reads or writes, and no infinite looping in the decompressor.
-So it's certainly pretty robust, although
-I wouldn't claim it to be totally bombproof.
-
-The file bzlib.h contains
-all definitions needed to use the library.  In particular, you
-should definitely not include
-bzlib_private.h.
-
-In bzlib.h, the various
-return values are defined.  The following list is not intended as
-an exhaustive description of the circumstances in which a given
-value may be returned -- those descriptions are given later.
-Rather, it is intended to convey the rough meaning of each return
-value.  The first five actions are normal and not intended to
-denote an error situation.
-
-
-
- 
-  BZ_OK
-  The requested action was completed
-   successfully.
- 
-
- 
-  BZ_RUN_OK, BZ_FLUSH_OK,
-    BZ_FINISH_OK
-  In 
-   BZ2_bzCompress, the requested
-   flush/finish/nothing-special action was completed
-   successfully.
- 
-
- 
-  BZ_STREAM_END
-  Compression of data was completed, or the
-   logical stream end was detected during
-   decompression.
- 
-
-
-
-The following return values indicate an error of some
-kind.
-
-
-
- 
-  BZ_CONFIG_ERROR
-  Indicates that the library has been improperly
-   compiled on your platform -- a major configuration error.
-   Specifically, it means that
-   sizeof(char),
-   sizeof(short) and
-   sizeof(int) are not 1, 2 and
-   4 respectively, as they should be.  Note that the library
-   should still work properly on 64-bit platforms which follow
-   the LP64 programming model -- that is, where
-   sizeof(long) and
-   sizeof(void*) are 8.  Under
-   LP64, sizeof(int) is still 4,
-   so libbzip2, which doesn't
-   use the long type, is
-   OK.
- 
-
- 
-  BZ_SEQUENCE_ERROR
-  When using the library, it is important to call
-   the functions in the correct sequence and with data structures
-   (buffers etc) in the correct states.
-   libbzip2 checks as much as it
-   can to ensure this is happening, and returns
-   BZ_SEQUENCE_ERROR if not.
-   Code which complies precisely with the function semantics, as
-   detailed below, should never receive this value; such an event
-   denotes buggy code which you should
-   investigate.
- 
-
- 
-  BZ_PARAM_ERROR
-  Returned when a parameter to a function call is
-   out of range or otherwise manifestly incorrect.  As with
-   BZ_SEQUENCE_ERROR, this
-   denotes a bug in the client code.  The distinction between
-   BZ_PARAM_ERROR and
-   BZ_SEQUENCE_ERROR is a bit
-   hazy, but still worth making.
- 
-
- 
-  BZ_MEM_ERROR
-  Returned when a request to allocate memory
-   failed.  Note that the quantity of memory needed to decompress
-   a stream cannot be determined until the stream's header has
-   been read.  So
-   BZ2_bzDecompress and
-   BZ2_bzRead may return
-   BZ_MEM_ERROR even though some
-   of the compressed data has been read.  The same is not true
-   for compression; once
-   BZ2_bzCompressInit or
-   BZ2_bzWriteOpen have
-   successfully completed,
-   BZ_MEM_ERROR cannot
-   occur.
- 
-
- 
-  BZ_DATA_ERROR
-  Returned when a data integrity error is
-   detected during decompression.  Most importantly, this means
-   when stored and computed CRCs for the data do not match.  This
-   value is also returned upon detection of any other anomaly in
-   the compressed data.
- 
-
- 
-  BZ_DATA_ERROR_MAGIC
-  As a special case of
-   BZ_DATA_ERROR, it is
-   sometimes useful to know when the compressed stream does not
-   start with the correct magic bytes ('B' 'Z'
-   'h').
- 
-
- 
-  BZ_IO_ERROR
-  Returned by
-   BZ2_bzRead and
-   BZ2_bzWrite when there is an
-   error reading or writing in the compressed file, and by
-   BZ2_bzReadOpen and
-   BZ2_bzWriteOpen for attempts
-   to use a file for which the error indicator (viz,
-   ferror(f)) is set.  On
-   receipt of BZ_IO_ERROR, the
-   caller should consult errno
-   and/or perror to acquire
-   operating-system specific information about the
-   problem.
- 
-
- 
-  BZ_UNEXPECTED_EOF
-  Returned by
-   BZ2_bzRead when the
-   compressed file finishes before the logical end of stream is
-   detected.
- 
-
- 
-  BZ_OUTBUFF_FULL
-  Returned by
-   BZ2_bzBuffToBuffCompress and
-   BZ2_bzBuffToBuffDecompress to
-   indicate that the output data will not fit into the output
-   buffer provided.

-                         int workFactor );
-
-
-Prepares for compression.  The
-bz_stream structure holds all
-data pertaining to the compression activity.  A
-bz_stream structure should be
-allocated and initialised prior to the call.  The fields of
-bz_stream comprise the entirety
-of the user-visible data.  state
-is a pointer to the private data structures required for
-compression.
-
-Custom memory allocators are supported, via fields
-bzalloc,
-bzfree, and
-opaque.  The value
-opaque is passed to as the first
-argument to all calls to bzalloc
-and bzfree, but is otherwise
-ignored by the library.  The call bzalloc (
-opaque, n, m ) is expected to return a pointer
-p to n *
-m bytes of memory, and bzfree (
-opaque, p ) should free that memory.
-
-If you don't want to use a custom memory allocator, set
-bzalloc,
-bzfree and
-opaque to
-NULL, and the library will then
-use the standard malloc /
-free routines.
-
-Before calling
-BZ2_bzCompressInit, fields
-bzalloc,
-bzfree and
-opaque should be filled
-appropriately, as just described.  Upon return, the internal
-state will have been allocated and initialised, and
-total_in_lo32,
-total_in_hi32,
-total_out_lo32 and
-total_out_hi32 will have been
-set to zero.  These four fields are used by the library to inform
-the caller of the total amount of data passed into and out of the
-library, respectively.  You should not try to change them.  As of
-version 1.0, 64-bit counts are maintained, even on 32-bit
-platforms, using the _hi32
-fields to store the upper 32 bits of the count.  So, for example,
-the total amount of data in is (total_in_hi32
-<< 32) + total_in_lo32.
-
-Parameter blockSize100k
-specifies the block size to be used for compression.  It should
-be a value between 1 and 9 inclusive, and the actual block size
-used is 100000 x this figure.  9 gives the best compression but
-takes most memory.
-
-Parameter verbosity should
-be set to a number between 0 and 4 inclusive.  0 is silent, and
-greater numbers give increasingly verbose monitoring/debugging
-output.  If the library has been compiled with
--DBZ_NO_STDIO, no such output
-will appear for any verbosity setting.
-
-Parameter workFactor
-controls how the compression phase behaves when presented with
-worst case, highly repetitive, input data.  If compression runs
-into difficulties caused by repetitive data, the library switches
-from the standard sorting algorithm to a fallback algorithm.  The
-fallback is slower than the standard algorithm by perhaps a
-factor of three, but always behaves reasonably, no matter how bad
-the input.
-
-Lower values of workFactor
-reduce the amount of effort the standard algorithm will expend
-before resorting to the fallback.  You should set this parameter
-carefully; too low, and many inputs will be handled by the
-fallback algorithm and so compress rather slowly, too high, and
-your average-to-worst case compression times can become very
-large.  The default value of 30 gives reasonable behaviour over a
-wide range of circumstances.
-
-Allowable values range from 0 to 250 inclusive.  0 is a
-special case, equivalent to using the default value of 30.
-
-Note that the compressed output generated is the same
-regardless of whether or not the fallback algorithm is
-used.
-
-Be aware also that this parameter may disappear entirely in
-future versions of the library.  In principle it should be
-possible to devise a good way to automatically choose which
-algorithm to use.  Such a mechanism would render the parameter
-obsolete.
-
-Possible return values:
-
-
-BZ_CONFIG_ERROR
-  if the library has been mis-compiled
-BZ_PARAM_ERROR
-  if strm is NULL 
-  or blockSize < 1 or blockSize > 9
-  or verbosity < 0 or verbosity > 4
-  or workFactor < 0 or workFactor > 250
-BZ_MEM_ERROR 
-  if not enough memory is available
-BZ_OK 
-  otherwise
-
-
-Allowable next actions:
-
-
-BZ2_bzCompress
-  if BZ_OK is returned
-  no specific action needed in case of error
-
-
-
-
-
-
-BZ2_bzCompress
-
-
-int BZ2_bzCompress ( bz_stream *strm, int action );
-
-
-Provides more input and/or output buffer space for the
-library.  The caller maintains input and output buffers, and
-calls BZ2_bzCompress to transfer
-data between them.
-
-Before each call to
-BZ2_bzCompress,
-next_in should point at the data
-to be compressed, and avail_in
-should indicate how many bytes the library may read.
-BZ2_bzCompress updates
-next_in,
-avail_in and
-total_in to reflect the number
-of bytes it has read.
-
-Similarly, next_out should
-point to a buffer in which the compressed data is to be placed,
-with avail_out indicating how
-much output space is available.
-BZ2_bzCompress updates
-next_out,
-avail_out and
-total_out to reflect the number
-of bytes output.
-
-You may provide and remove as little or as much data as you
-like on each call of
-BZ2_bzCompress.  In the limit,
-it is acceptable to supply and remove data one byte at a time,
-although this would be terribly inefficient.  You should always
-ensure that at least one byte of output space is available at
-each call.
-
-A second purpose of
-BZ2_bzCompress is to request a
-change of mode of the compressed stream.
-
-Conceptually, a compressed stream can be in one of four
-states: IDLE, RUNNING, FLUSHING and FINISHING.  Before
-initialisation
-(BZ2_bzCompressInit) and after
-termination (BZ2_bzCompressEnd),
-a stream is regarded as IDLE.
-
-Upon initialisation
-(BZ2_bzCompressInit), the stream
-is placed in the RUNNING state.  Subsequent calls to
-BZ2_bzCompress should pass
-BZ_RUN as the requested action;
-other actions are illegal and will result in
-BZ_SEQUENCE_ERROR.
-
-At some point, the calling program will have provided all
-the input data it wants to.  It will then want to finish up -- in
-effect, asking the library to process any data it might have
-buffered internally.  In this state,
-BZ2_bzCompress will no longer
-attempt to read data from
-next_in, but it will want to
-write data to next_out.  Because
-the output buffer supplied by the user can be arbitrarily small,
-the finishing-up operation cannot necessarily be done with a
-single call of
-BZ2_bzCompress.
-
-Instead, the calling program passes
-BZ_FINISH as an action to
-BZ2_bzCompress.  This changes
-the stream's state to FINISHING.  Any remaining input (ie,
-next_in[0 .. avail_in-1]) is
-compressed and transferred to the output buffer.  To do this,
-BZ2_bzCompress must be called
-repeatedly until all the output has been consumed.  At that
-point, BZ2_bzCompress returns
-BZ_STREAM_END, and the stream's
-state is set back to IDLE.
-BZ2_bzCompressEnd should then be
-called.
-
-Just to make sure the calling program does not cheat, the
-library makes a note of avail_in
-at the time of the first call to
-BZ2_bzCompress which has
-BZ_FINISH as an action (ie, at
-the time the program has announced its intention to not supply
-any more input).  By comparing this value with that of
-avail_in over subsequent calls
-to BZ2_bzCompress, the library
-can detect any attempts to slip in more data to compress.  Any
-calls for which this is detected will return
-BZ_SEQUENCE_ERROR.  This
-indicates a programming mistake which should be corrected.
-
-Instead of asking to finish, the calling program may ask
-BZ2_bzCompress to take all the
-remaining input, compress it and terminate the current
-(Burrows-Wheeler) compression block.  This could be useful for
-error control purposes.  The mechanism is analogous to that for
-finishing: call BZ2_bzCompress
-with an action of BZ_FLUSH,
-remove output data, and persist with the
-BZ_FLUSH action until the value
-BZ_RUN is returned.  As with
-finishing, BZ2_bzCompress
-detects any attempt to provide more input data once the flush has
-begun.
-
-Once the flush is complete, the stream returns to the
-normal RUNNING state.
-
-This all sounds pretty complex, but isn't really.  Here's a
-table which shows which actions are allowable in each state, what
-action will be taken, what the next state is, and what the
-non-error return values are.  Note that you can't explicitly ask
-what state the stream is in, but nor do you need to -- it can be
-inferred from the values returned by
-BZ2_bzCompress.
-
-
-IDLE/any
-  Illegal.  IDLE state only exists after BZ2_bzCompressEnd or
-  before BZ2_bzCompressInit.
-  Return value = BZ_SEQUENCE_ERROR
-
-RUNNING/BZ_RUN
-  Compress from next_in to next_out as much as possible.
-  Next state = RUNNING
-  Return value = BZ_RUN_OK
-
-RUNNING/BZ_FLUSH
-  Remember current value of next_in. Compress from next_in
-  to next_out as much as possible, but do not accept any more input.
-  Next state = FLUSHING
-  Return value = BZ_FLUSH_OK
-
-RUNNING/BZ_FINISH
-  Remember current value of next_in. Compress from next_in
-  to next_out as much as possible, but do not accept any more input.
-  Next state = FINISHING
-  Return value = BZ_FINISH_OK
-
-FLUSHING/BZ_FLUSH
-  Compress from next_in to next_out as much as possible, 
-  but do not accept any more input.
-  If all the existing input has been used up and all compressed
-  output has been removed
-    Next state = RUNNING; Return value = BZ_RUN_OK
-  else
-    Next state = FLUSHING; Return value = BZ_FLUSH_OK
-
-FLUSHING/other     
-  Illegal.
-  Return value = BZ_SEQUENCE_ERROR
-
-FINISHING/BZ_FINISH
-  Compress from next_in to next_out as much as possible,
-  but to not accept any more input.  
-  If all the existing input has been used up and all compressed
-  output has been removed
-    Next state = IDLE; Return value = BZ_STREAM_END
-  else
-    Next state = FINISHING; Return value = BZ_FINISH_OK
-
-FINISHING/other
-  Illegal.
-  Return value = BZ_SEQUENCE_ERROR
-
-
-
-That still looks complicated?  Well, fair enough.  The
-usual sequence of calls for compressing a load of data is:
-
-
-
- Get started with
-  BZ2_bzCompressInit.
-
- Shovel data in and shlurp out its compressed form
-  using zero or more calls of
-  BZ2_bzCompress with action =
-  BZ_RUN.
-
- Finish up. Repeatedly call
-  BZ2_bzCompress with action =
-  BZ_FINISH, copying out the
-  compressed output, until
-  BZ_STREAM_END is
-  returned. Close up and go home.  Call
-  BZ2_bzCompressEnd.
-
-
-
-If the data you want to compress fits into your input
-buffer all at once, you can skip the calls of
-BZ2_bzCompress ( ..., BZ_RUN )
-and just do the BZ2_bzCompress ( ..., BZ_FINISH
-) calls.
-
-All required memory is allocated by
-BZ2_bzCompressInit.  The
-compression library can accept any data at all (obviously).  So
-you shouldn't get any error return values from the
-BZ2_bzCompress calls.  If you
-do, they will be
-BZ_SEQUENCE_ERROR, and indicate
-a bug in your programming.
-
-Trivial other possible return values:
-
-
-BZ_PARAM_ERROR
-  if strm is NULL, or strm->s is NULL
-
-
-
-
-
-
-BZ2_bzCompressEnd
-
-
-int BZ2_bzCompressEnd ( bz_stream *strm );
-
-
-Releases all memory associated with a compression
-stream.

-
-BZ2_bzDecompressInit
-
-
-int BZ2_bzDecompressInit ( bz_stream *strm, int verbosity, int small );
-
-
-Prepares for decompression.  As with
-BZ2_bzCompressInit, a
-bz_stream record should be
-allocated and initialised before the call.  Fields
-bzalloc,
-bzfree and
-opaque should be set if a custom
-memory allocator is required, or made
-NULL for the normal
-malloc /
-free routines.  Upon return, the
-internal state will have been initialised, and
-total_in and
-total_out will be zero.
-
-For the meaning of parameter
-verbosity, see
-BZ2_bzCompressInit.
-
-If small is nonzero, the
-library will use an alternative decompression algorithm which
-uses less memory but at the cost of decompressing more slowly
-(roughly speaking, half the speed, but the maximum memory
-requirement drops to around 2300k).  See 
-for more information on memory management.
-
-Note that the amount of memory needed to decompress a
-stream cannot be determined until the stream's header has been
-read, so even if
-BZ2_bzDecompressInit succeeds, a
-subsequent BZ2_bzDecompress
-could fail with
-BZ_MEM_ERROR.
-
-Possible return values:
-
-
-BZ_CONFIG_ERROR

-int BZ2_bzDecompress ( bz_stream *strm );
-
-
-Provides more input and/out output buffer space for the
-library.  The caller maintains input and output buffers, and uses
-BZ2_bzDecompress to transfer
-data between them.
-
-Before each call to
-BZ2_bzDecompress,
-next_in should point at the
-compressed data, and avail_in
-should indicate how many bytes the library may read.
-BZ2_bzDecompress updates
-next_in,
-avail_in and
-total_in to reflect the number
-of bytes it has read.
-
-Similarly, next_out should
-point to a buffer in which the uncompressed output is to be
-placed, with avail_out
-indicating how much output space is available.
-BZ2_bzCompress updates
-next_out,
-avail_out and
-total_out to reflect the number
-of bytes output.
-
-You may provide and remove as little or as much data as you
-like on each call of
-BZ2_bzDecompress.  In the limit,
-it is acceptable to supply and remove data one byte at a time,
-although this would be terribly inefficient.  You should always
-ensure that at least one byte of output space is available at
-each call.
-
-Use of BZ2_bzDecompress is
-simpler than
-BZ2_bzCompress.
-
-You should provide input and remove output as described
-above, and repeatedly call
-BZ2_bzDecompress until
-BZ_STREAM_END is returned.
-Appearance of BZ_STREAM_END
-denotes that BZ2_bzDecompress
-has detected the logical end of the compressed stream.
-BZ2_bzDecompress will not
-produce BZ_STREAM_END until all
-output data has been placed into the output buffer, so once
-BZ_STREAM_END appears, you are
-guaranteed to have available all the decompressed output, and
-BZ2_bzDecompressEnd can safely
-be called.
-
-If case of an error return value, you should call
-BZ2_bzDecompressEnd to clean up
-and release memory.
-
-Possible return values:
-
-
-BZ_PARAM_ERROR
-  if strm is NULL or strm->s is NULL
-  or strm->avail_out < 1
-BZ_DATA_ERROR
-  if a data integrity error is detected in the compressed stream
-BZ_DATA_ERROR_MAGIC
-  if the compressed stream doesn't begin with the right magic bytes
-BZ_MEM_ERROR
-  if there wasn't enough memory available
-BZ_STREAM_END
-  if the logical end of the data stream was detected and all
-  output in has been consumed, eg s-->avail_out > 0

-High-level interface
-
-This interface provides functions for reading and writing
-bzip2 format files.  First, some
-general points.
-
-
-
- All of the functions take an
-  int* first argument,
-  bzerror.  After each call,
-  bzerror should be consulted
-  first to determine the outcome of the call.  If
-  bzerror is
-  BZ_OK, the call completed
-  successfully, and only then should the return value of the
-  function (if any) be consulted.  If
-  bzerror is
-  BZ_IO_ERROR, there was an
-  error reading/writing the underlying compressed file, and you
-  should then consult errno /
-  perror to determine the cause
-  of the difficulty.  bzerror
-  may also be set to various other values; precise details are
-  given on a per-function basis below.
-
- If bzerror indicates
-  an error (ie, anything except
-  BZ_OK and
-  BZ_STREAM_END), you should
-  immediately call
-  BZ2_bzReadClose (or
-  BZ2_bzWriteClose, depending on
-  whether you are attempting to read or to write) to free up all
-  resources associated with the stream.  Once an error has been
-  indicated, behaviour of all calls except
-  BZ2_bzReadClose
-  (BZ2_bzWriteClose) is
-  undefined.  The implication is that (1)
-  bzerror should be checked
-  after each call, and (2) if
-  bzerror indicates an error,
-  BZ2_bzReadClose
-  (BZ2_bzWriteClose) should then
-  be called to clean up.
-
- The FILE* arguments
-  passed to BZ2_bzReadOpen /
-  BZ2_bzWriteOpen should be set
-  to binary mode.  Most Unix systems will do this by default, but
-  other platforms, including Windows and Mac, will not.  If you
-  omit this, you may encounter problems when moving code to new
-  platforms.
-
- Memory allocation requests are handled by
-  malloc /
-  free.  At present there is no
-  facility for user-defined memory allocators in the file I/O
-  functions (could easily be added, though).
-
-
-
-
-
-
-BZ2_bzReadOpen
-
-
-typedef void BZFILE;
-
-BZFILE *BZ2_bzReadOpen( int *bzerror, FILE *f, 
-                        int verbosity, int small,
-                        void *unused, int nUnused );
-
-
-Prepare to read compressed data from file handle
-f.
-f should refer to a file which
-has been opened for reading, and for which the error indicator
-(ferror(f))is not set.  If
-small is 1, the library will try
-to decompress using less memory, at the expense of speed.
-
-For reasons explained below,
-BZ2_bzRead will decompress the
-nUnused bytes starting at
-unused, before starting to read
-from the file f.  At most
-BZ_MAX_UNUSED bytes may be
-supplied like this.  If this facility is not required, you should
-pass NULL and
-0 for
-unused and
-nUnused respectively.
-
-For the meaning of parameters
-small and
-verbosity, see
-BZ2_bzDecompressInit.
-
-The amount of memory needed to decompress a file cannot be
-determined until the file's header has been read.  So it is
-possible that BZ2_bzReadOpen
-returns BZ_OK but a subsequent
-call of BZ2_bzRead will return
-BZ_MEM_ERROR.
-
-Possible assignments to
-bzerror:
-
-
-BZ_CONFIG_ERROR
-  if the library has been mis-compiled
-BZ_PARAM_ERROR
-  if f is NULL
-  or small is neither 0 nor 1
-  or ( unused == NULL && nUnused != 0 )
-  or ( unused != NULL && !(0 <= nUnused <= BZ_MAX_UNUSED) )
-BZ_IO_ERROR
-  if ferror(f) is nonzero
-BZ_MEM_ERROR
-  if insufficient memory is available
-BZ_OK
-  otherwise.
-
-
-Possible return values:
-
-
-Pointer to an abstract BZFILE
-  if bzerror is BZ_OK
-NULL
-  otherwise
-
-
-Allowable next actions:
-
-
-BZ2_bzRead

-  otherwise
-
-
-
-
-
-
-BZ2_bzRead
-
-
-int BZ2_bzRead ( int *bzerror, BZFILE *b, void *buf, int len );
-
-
-Reads up to len
-(uncompressed) bytes from the compressed file
-b into the buffer
-buf.  If the read was
-successful, bzerror is set to
-BZ_OK and the number of bytes
-read is returned.  If the logical end-of-stream was detected,
-bzerror will be set to
-BZ_STREAM_END, and the number of
-bytes read is returned.  All other
-bzerror values denote an
-error.
-
-BZ2_bzRead will supply
-len bytes, unless the logical
-stream end is detected or an error occurs.  Because of this, it
-is possible to detect the stream end by observing when the number
-of bytes returned is less than the number requested.
-Nevertheless, this is regarded as inadvisable; you should instead
-check bzerror after every call
-and watch out for
-BZ_STREAM_END.
-
-Internally, BZ2_bzRead
-copies data from the compressed file in chunks of size
-BZ_MAX_UNUSED bytes before
-decompressing it.  If the file contains more bytes than strictly
-needed to reach the logical end-of-stream,
-BZ2_bzRead will almost certainly
-read some of the trailing data before signalling
-BZ_SEQUENCE_END.  To collect the
-read but unused data once
-BZ_SEQUENCE_END has appeared,
-call BZ2_bzReadGetUnused
-immediately before
-BZ2_bzReadClose.
-
-Possible assignments to
-bzerror:
-
-
-BZ_PARAM_ERROR
-  if b is NULL or buf is NULL or len < 0
-BZ_SEQUENCE_ERROR
-  if b was opened with BZ2_bzWriteOpen
-BZ_IO_ERROR
-  if there is an error reading from the compressed file
-BZ_UNEXPECTED_EOF
-  if the compressed file ended before 
-  the logical end-of-stream was detected
-BZ_DATA_ERROR
-  if a data integrity error was detected in the compressed stream
-BZ_DATA_ERROR_MAGIC
-  if the stream does not begin with the requisite header bytes 
-  (ie, is not a bzip2 data file).  This is really 
-  a special case of BZ_DATA_ERROR.
-BZ_MEM_ERROR
-  if insufficient memory was available
-BZ_STREAM_END
-  if the logical end of stream was detected.
-BZ_OK
-  otherwise.
-
-
-Possible return values:

-
-
-Returns data which was read from the compressed file but

-*unused is set to the address of

-
-
-Prepare to write compressed data to file handle

-f should refer to a file which

-(ferror(f))is not set.
-
-For the meaning of parameters
-blockSize100k,

-
-All required memory is allocated at this stage, so if the

-void BZ2_bzWrite ( int *bzerror, BZFILE *b, void *buf, int len );

-                         unsigned int* nbytes_out_hi32 );
-
-
-Compresses and flushes to the compressed file all data so
-far supplied by BZ2_bzWrite.
-The logical end-of-stream markers are also written, so subsequent
-calls to BZ2_bzWrite are
-illegal.  All memory associated with the compressed file
-b is released.
-fflush is called on the
-compressed file, but it is not
-fclose'd.
-
-If BZ2_bzWriteClose is
-called to clean up after an error, the only action is to release
-the memory.  The library records the error codes issued by
-previous calls, so this situation will be detected automatically.
-There is no attempt to complete the compression operation, nor to
-fflush the compressed file.  You
-can force this behaviour to happen even in the case of no error,
-by passing a nonzero value to
-abandon.
-
-If nbytes_in is non-null,
-*nbytes_in will be set to be the
-total volume of uncompressed data handled.  Similarly,
-nbytes_out will be set to the
-total volume of compressed data written.  For compatibility with
-older versions of the library,
-BZ2_bzWriteClose only yields the
-lower 32 bits of these counts.  Use
-BZ2_bzWriteClose64 if you want
-the full 64 bit counts.  These two functions are otherwise
-absolutely identical.
-
-Possible assignments to
-bzerror:
-
-
-BZ_SEQUENCE_ERROR
-  if b was opened with BZ2_bzReadOpen
-BZ_IO_ERROR
-  if there is an error writing the compressed file
-BZ_OK
-  otherwise
-
-
-
-
-
-
-Handling embedded compressed data streams
-
-The high-level library facilitates use of
-bzip2 data streams which form
-some part of a surrounding, larger data stream.
-
-
-
- For writing, the library takes an open file handle,
-  writes compressed data to it,
-  fflushes it but does not
-  fclose it.  The calling
-  application can write its own data before and after the
-  compressed data stream, using that same file handle.
-
- Reading is more complex, and the facilities are not as
-  general as they could be since generality is hard to reconcile
-  with efficiency.  BZ2_bzRead
-  reads from the compressed file in blocks of size
-  BZ_MAX_UNUSED bytes, and in
-  doing so probably will overshoot the logical end of compressed
-  stream.  To recover this data once decompression has ended,
-  call BZ2_bzReadGetUnused after
-  the last call of BZ2_bzRead
-  (the one returning
-  BZ_STREAM_END) but before
-  calling
-  BZ2_bzReadClose.
-
-
-
-This mechanism makes it easy to decompress multiple
-bzip2 streams placed end-to-end.
-As the end of one stream, when
-BZ2_bzRead returns
-BZ_STREAM_END, call
-BZ2_bzReadGetUnused to collect
-the unused data (copy it into your own buffer somewhere).  That
-data forms the start of the next compressed stream.  To start
-uncompressing that next stream, call
-BZ2_bzReadOpen again, feeding in
-the unused data via the unused /
-nUnused parameters.  Keep doing
-this until BZ_STREAM_END return
-coincides with the physical end of file
-(feof(f)).  In this situation
-BZ2_bzReadGetUnused will of
-course return no data.
-
-This should give some feel for how the high-level interface
-can be used.  If you require extra flexibility, you'll have to
-bite the bullet and get to grips with the low-level
-interface.
-
-
-
-
-
-Standard file-reading/writing code
-
-Here's how you'd write data to a compressed file:
-
-
-FILE*   f;
-BZFILE* b;
-int     nBuf;
-char    buf[ /* whatever size you like */ ];
-int     bzerror;
-int     nWritten;
-
-f = fopen ( "myfile.bz2", "w" );
-if ( !f ) {
- /* handle error */
-}
-b = BZ2_bzWriteOpen( &bzerror, f, 9 );
-if (bzerror != BZ_OK) {
- BZ2_bzWriteClose ( b );
- /* handle error */
-}
-
-while ( /* condition */ ) {
- /* get data to write into buf, and set nBuf appropriately */
- nWritten = BZ2_bzWrite ( &bzerror, b, buf, nBuf );
- if (bzerror == BZ_IO_ERROR) { 
-   BZ2_bzWriteClose ( &bzerror, b );
-   /* handle error */
- }
-}
-
-BZ2_bzWriteClose( &bzerror, b );
-if (bzerror == BZ_IO_ERROR) {
- /* handle error */
-}
-
-
-And to read from a compressed file:
-
-
-FILE*   f;
-BZFILE* b;
-int     nBuf;
-char    buf[ /* whatever size you like */ ];
-int     bzerror;
-int     nWritten;
-
-f = fopen ( "myfile.bz2", "r" );
-if ( !f ) {
-  /* handle error */
-}
-b = BZ2_bzReadOpen ( &bzerror, f, 0, NULL, 0 );
-if ( bzerror != BZ_OK ) {
-  BZ2_bzReadClose ( &bzerror, b );
-  /* handle error */
-}
-
-bzerror = BZ_OK;
-while ( bzerror == BZ_OK && /* arbitrary other conditions */) {
-  nBuf = BZ2_bzRead ( &bzerror, b, buf, /* size of buf */ );
-  if ( bzerror == BZ_OK ) {
-    /* do something with buf[0 .. nBuf-1] */
-  }
-}
-if ( bzerror != BZ_STREAM_END ) {
-   BZ2_bzReadClose ( &bzerror, b );
-   /* handle error */
-} else {
-   BZ2_bzReadClose ( &bzerror, b );

-
-
-Attempts to compress the data in source[0
-.. sourceLen-1] into the destination buffer,
-dest[0 .. *destLen-1].  If the

-BZ_OUTBUFF_FULL is
-returned.
-
-Compression in this manner is a one-shot event, done with a

-
-For the meaning of parameters

-Attempts to decompress the data in source[0

-zlib compatibility functions
-
-Yoshioka Tsuneo has contributed some functions to give
-better zlib compatibility.
-These functions are BZ2_bzopen,
-BZ2_bzread,
-BZ2_bzwrite,
-BZ2_bzflush,
-BZ2_bzclose,
-BZ2_bzerror and
-BZ2_bzlibVersion.  These
-functions are not (yet) officially part of the library.  If they
-break, you get to keep all the pieces.  Nevertheless, I think
-they work ok.
-
-
-typedef void BZFILE;
-
-const char * BZ2_bzlibVersion ( void );
-
-
-Returns a string indicating the library version.
-
-
-BZFILE * BZ2_bzopen  ( const char *path, const char *mode );
-BZFILE * BZ2_bzdopen ( int        fd,    const char *mode );
-
-
-Opens a .bz2 file for
-reading or writing, using either its name or a pre-existing file
-descriptor.  Analogous to fopen
-and fdopen.
-
-
-int BZ2_bzread  ( BZFILE* b, void* buf, int len );
-int BZ2_bzwrite ( BZFILE* b, void* buf, int len );
-
-
-Reads/writes data from/to a previously opened
-BZFILE.  Analogous to
-fread and
-fwrite.
-
-
-int  BZ2_bzflush ( BZFILE* b );
-void BZ2_bzclose ( BZFILE* b );
-
-
-Flushes/closes a BZFILE.
-BZ2_bzflush doesn't actually do
-anything.  Analogous to fflush
-and fclose.
-
-
-const char * BZ2_bzerror ( BZFILE *b, int *errnum )
-
-
-Returns a string describing the more recent error status of
-b, and also sets
-*errnum to its numerical
-value.
-

-
-Using the library in a stdio-free environment
-
-
-
-Getting rid of stdio
-
-In a deeply embedded application, you might want to use
-just the memory-to-memory functions.  You can do this
-conveniently by compiling the library with preprocessor symbol
-BZ_NO_STDIO defined.  Doing this
-gives you a library containing only the following eight
-functions:
-
-BZ2_bzCompressInit,
-BZ2_bzCompress,
-BZ2_bzCompressEnd
-BZ2_bzDecompressInit,
-BZ2_bzDecompress,
-BZ2_bzDecompressEnd
-BZ2_bzBuffToBuffCompress,
-BZ2_bzBuffToBuffDecompress
-
-When compiled like this, all functions will ignore
-verbosity settings.
-
-
-
-
-
-Critical error handling
-
-libbzip2 contains a number
-of internal assertion checks which should, needless to say, never
-be activated.  Nevertheless, if an assertion should fail,
-behaviour depends on whether or not the library was compiled with
-BZ_NO_STDIO set.
-
-For a normal compile, an assertion failure yields the
-message:
-
-

-bzip2/libbzip2: internal error number N.
-This is a bug in bzip2/libbzip2, &bz-version; of &bz-date;.
-Please report it to: &bz-email;.  If this happened
-when you were using some program which uses libbzip2 as a
-component, you should also report this bug to the author(s)
-of that program.  Please make an effort to report this bug;
-timely and accurate bug reports eventually lead to higher
-quality software.  Thanks.
-

-
-where N is some error code
-number.  If N == 1007, it also
-prints some extra text advising the reader that unreliable memory
-is often associated with internal error 1007. (This is a
-frequently-observed-phenomenon with versions 1.0.0/1.0.1).
-
-exit(3) is then
-called.
-
-For a stdio-free library,
-assertion failures result in a call to a function declared
-as:
-
-
-extern void bz_internal_error ( int errcode );
-
-
-The relevant code is passed as a parameter.  You should
-supply such a function.
-
-In either case, once an assertion failure has occurred, any
-bz_stream records involved can
-be regarded as invalid.  You should not attempt to resume normal
-operation with them.
-
-You may, of course, change critical error handling to suit
-your needs.  As I said above, critical errors indicate bugs in
-the library and should not occur.  All "normal" error situations
-are indicated via error return codes from functions, and can be
-recovered from.

-Making a Windows DLL
-
-Everything related to Windows has been contributed by
-Yoshioka Tsuneo
-(tsuneo@rr.iij4u.or.jp), so
-you should send your queries to him (but please Cc:
-&bz-email;).
-
-My vague understanding of what to do is: using Visual C++
-5.0, open the project file
-libbz2.dsp, and build.  That's
-all.
-
-If you can't open the project file for some reason, make a
-new one, naming these files:
-blocksort.c,
-bzlib.c,
-compress.c,
-crctable.c,
-decompress.c,
-huffman.c,
-randtable.c and
-libbz2.def.  You will also need
-to name the header files bzlib.h
-and bzlib_private.h.
-
-If you don't use VC++, you may need to define the
-proprocessor symbol
-_WIN32.
-
-Finally, dlltest.c is a
-sample program using the DLL.  It has a project file,
-dlltest.dsp.
-
-If you just want a makefile for Visual C, have a look at
-makefile.msc.
-
-Be aware that if you compile
-bzip2 itself on Win32, you must
-set BZ_UNIX to 0 and
-BZ_LCCWIN32 to 1, in the file
-bzip2.c, before compiling.
-Otherwise the resulting binary won't work correctly.
-
-I haven't tried any of this stuff myself, but it all looks
-plausible.
-
-
-
-
-
-
-
-
-Miscellanea
-
-These are just some random thoughts of mine.  Your mileage
-may vary.
-
-
-
-Limitations of the compressed file format
-
-bzip2-1.0.X,
-0.9.5 and
-0.9.0 use exactly the same file
-format as the original version,
-bzip2-0.1.  This decision was
-made in the interests of stability.  Creating yet another
-incompatible compressed file format would create further
-confusion and disruption for users.
-
-Nevertheless, this is not a painless decision.  Development
-work since the release of
-bzip2-0.1 in August 1997 has
-shown complexities in the file format which slow down
-decompression and, in retrospect, are unnecessary.  These
-are:
-
-
-
- The run-length encoder, which is the first of the
-   compression transformations, is entirely irrelevant.  The
-   original purpose was to protect the sorting algorithm from the
-   very worst case input: a string of repeated symbols.  But
-   algorithm steps Q6a and Q6b in the original Burrows-Wheeler
-   technical report (SRC-124) show how repeats can be handled
-   without difficulty in block sorting.
-
- The randomisation mechanism doesn't really need to be
-   there.  Udi Manber and Gene Myers published a suffix array
-   construction algorithm a few years back, which can be employed
-   to sort any block, no matter how repetitive, in O(N log N)
-   time.  Subsequent work by Kunihiko Sadakane has produced a
-   derivative O(N (log N)^2) algorithm which usually outperforms
-   the Manber-Myers algorithm.
-
-   I could have changed to Sadakane's algorithm, but I find
-   it to be slower than bzip2's
-   existing algorithm for most inputs, and the randomisation
-   mechanism protects adequately against bad cases.  I didn't
-   think it was a good tradeoff to make.  Partly this is due to
-   the fact that I was not flooded with email complaints about
-   bzip2-0.1's performance on
-   repetitive data, so perhaps it isn't a problem for real
-   inputs.
-
-   Probably the best long-term solution, and the one I have
-   incorporated into 0.9.5 and above, is to use the existing
-   sorting algorithm initially, and fall back to a O(N (log N)^2)
-   algorithm if the standard algorithm gets into
-   difficulties.
-
-  The compressed file format was never designed to be
-   handled by a library, and I have had to jump though some hoops
-   to produce an efficient implementation of decompression.  It's
-   a bit hairy.  Try passing
-   decompress.c through the C
-   preprocessor and you'll see what I mean.  Much of this
-   complexity could have been avoided if the compressed size of
-   each block of data was recorded in the data stream.
-
- An Adler-32 checksum, rather than a CRC32 checksum,
-   would be faster to compute.
-
-
-
-It would be fair to say that the
-bzip2 format was frozen before I
-properly and fully understood the performance consequences of
-doing so.
-
-Improvements which I was able to incorporate into 0.9.0,
-despite using the same file format, are:
-
-
-
- Single array implementation of the inverse BWT.  This
-  significantly speeds up decompression, presumably because it
-  reduces the number of cache misses.
-
- Faster inverse MTF transform for large MTF values.
-  The new implementation is based on the notion of sliding blocks
-  of values.
-
- bzip2-0.9.0 now reads
-  and writes files with fread
-  and fwrite; version 0.1 used
-  putc and
-  getc.  Duh!  Well, you live
-  and learn.
-
-
-
-Further ahead, it would be nice to be able to do random
-access into files.  This will require some careful design of
-compressed file formats.
-
-
-
-
-
-Portability issues
-
-After some consideration, I have decided not to use GNU
-autoconf to configure 0.9.5 or
-1.0.
-
-autoconf, admirable and
-wonderful though it is, mainly assists with portability problems
-between Unix-like platforms.  But
-bzip2 doesn't have much in the
-way of portability problems on Unix; most of the difficulties
-appear when porting to the Mac, or to Microsoft's operating
-systems.  autoconf doesn't help
-in those cases, and brings in a whole load of new
-complexity.
-
-Most people should be able to compile the library and
-program under Unix straight out-of-the-box, so to speak,
-especially if you have a version of GNU C available.
-
-There are a couple of
-__inline__ directives in the
-code.  GNU C (gcc) should be
-able to handle them.  If you're not using GNU C, your C compiler
-shouldn't see them at all.  If your compiler does, for some
-reason, see them and doesn't like them, just
-#define
-__inline__ to be
-/* */.  One easy way to do this
-is to compile with the flag
--D__inline__=, which should be
-understood by most Unix compilers.
-
-If you still have difficulties, try compiling with the
-macro BZ_STRICT_ANSI defined.
-This should enable you to build the library in a strictly ANSI
-compliant environment.  Building the program itself like this is
-dangerous and not supported, since you remove
-bzip2's checks against
-compressing directories, symbolic links, devices, and other
-not-really-a-file entities.  This could cause filesystem
-corruption!
-
-One other thing: if you create a
-bzip2 binary for public distribution,
-please consider linking it statically (gcc
--static).  This avoids all sorts of library-version
-issues that others may encounter later on.
-
-If you build bzip2 on
-Win32, you must set BZ_UNIX to 0
-and BZ_LCCWIN32 to 1, in the
-file bzip2.c, before compiling.
-Otherwise the resulting binary won't work correctly.
-
-
-
-
-
-Reporting bugs
-
-I tried pretty hard to make sure
-bzip2 is bug free, both by
-design and by testing.  Hopefully you'll never need to read this
-section for real.
-
-Nevertheless, if bzip2 dies
-with a segmentation fault, a bus error or an internal assertion
-failure, it will ask you to email me a bug report.  Experience from
-years of feedback of bzip2 users indicates that almost all these
-problems can be traced to either compiler bugs or hardware
-problems.
-
-
-
- Recompile the program with no optimisation, and
-  see if it works.  And/or try a different compiler.  I heard all
-  sorts of stories about various flavours of GNU C (and other
-  compilers) generating bad code for
-  bzip2, and I've run across two
-  such examples myself.
-
-  2.7.X versions of GNU C are known to generate bad code
-  from time to time, at high optimisation levels.  If you get
-  problems, try using the flags
-  -O2
-  -fomit-frame-pointer
-  -fno-strength-reduce.  You
-  should specifically not use
-  -funroll-loops.
-
-  You may notice that the Makefile runs six tests as part
-  of the build process.  If the program passes all of these, it's
-  a pretty good (but not 100%) indication that the compiler has
-  done its job correctly.
-
- If bzip2
-  crashes randomly, and the crashes are not repeatable, you may
-  have a flaky memory subsystem.
-  bzip2 really hammers your
-  memory hierarchy, and if it's a bit marginal, you may get these
-  problems.  Ditto if your disk or I/O subsystem is slowly
-  failing.  Yup, this really does happen.
-
-  Try using a different machine of the same type, and see
-  if you can repeat the problem.
-
-  This isn't really a bug, but ... If
-  bzip2 tells you your file is
-  corrupted on decompression, and you obtained the file via FTP,
-  there is a possibility that you forgot to tell FTP to do a
-  binary mode transfer.  That absolutely will cause the file to
-  be non-decompressible.  You'll have to transfer it
-  again.
-
-
-
-If you've incorporated
-libbzip2 into your own program
-and are getting problems, please, please, please, check that the
-parameters you are passing in calls to the library, are correct,
-and in accordance with what the documentation says is allowable.
-I have tried to make the library robust against such problems,
-but I'm sure I haven't succeeded.
-
-Finally, if the above comments don't help, you'll have to
-send me a bug report.  Now, it's just amazing how many people
-will send me a bug report saying something like:
-
-
-bzip2 crashed with segmentation fault on my machine
-
-
-and absolutely nothing else.  Needless to say, a such a
-report is totally, utterly, completely and
-comprehensively 100% useless; a waste of your time, my time, and
-net bandwidth.  With no details at all, there's no way
-I can possibly begin to figure out what the problem is.
-
-The rules of the game are: facts, facts, facts.  Don't omit
-them because "oh, they won't be relevant".  At the bare
-minimum:
-
-
-Machine type.  Operating system version.  
-Exact version of bzip2 (do bzip2 -V).  
-Exact version of the compiler used.  
-Flags passed to the compiler.
-
-
-However, the most important single thing that will help me
-is the file that you were trying to compress or decompress at the
-time the problem happened.  Without that, my ability to do
-anything more than speculate about the cause, is limited.
-
-
-
-
-
-Did you get the right package?
-
-bzip2 is a resource hog.
-It soaks up large amounts of CPU cycles and memory.  Also, it
-gives very large latencies.  In the worst case, you can feed many
-megabytes of uncompressed data into the library before getting
-any compressed output, so this probably rules out applications
-requiring interactive behaviour.
-
-These aren't faults of my implementation, I hope, but more
-an intrinsic property of the Burrows-Wheeler transform
-(unfortunately).  Maybe this isn't what you want.
-
-If you want a compressor and/or library which is faster,
-uses less memory but gets pretty good compression, and has
-minimal latency, consider Jean-loup Gailly's and Mark Adler's
-work, zlib-1.2.1 and
-gzip-1.2.4.  Look for them at 
-http://www.zlib.org and 
-http://www.gzip.org
-respectively.
-
-For something faster and lighter still, you might try Markus F
-X J Oberhumer's LZO real-time
-compression/decompression library, at 
-http://www.oberhumer.com/opensource.
