+ ZLib for Ada thick binding (ZLib.Ada)
+ Release 1.3
+
+ZLib.Ada is a thick binding interface to the popular ZLib data
+compression library, available at http://www.gzip.org/zlib/.
+It provides Ada-style access to the ZLib C library.
+
+
+ Here are the main changes since ZLib.Ada 1.2:
+
+- Attension: ZLib.Read generic routine have a initialization requirement
+ for Read_Last parameter now. It is a bit incompartible with previous version,
+ but extends functionality, we could use new parameters Allow_Read_Some and
+ Flush now.
+
+- Added Is_Open routines to ZLib and ZLib.Streams packages.
+
+- Add pragma Assert to check Stream_Element is 8 bit.
+
+- Fix extraction to buffer with exact known decompressed size. Error reported by
+ Steve Sangwine.
+
+- Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits
+ computers. Patch provided by Pascal Obry.
+
+- Add Status_Error exception definition.
+
+- Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit.
+
+
+ How to build ZLib.Ada under GNAT
+
+You should have the ZLib library already build on your computer, before
+building ZLib.Ada. Make the directory of ZLib.Ada sources current and
+issue the command:
+
+ gnatmake test -largs -L<directory where libz.a is> -lz
+
+Or use the GNAT project file build for GNAT 3.15 or later:
+
+ gnatmake -Pzlib.gpr -L<directory where libz.a is>
+
+
+ How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2
+
+1. Make a project with all *.ads and *.adb files from the distribution.
+2. Build the libz.a library from the ZLib C sources.
+3. Rename libz.a to z.lib.
+4. Add the library z.lib to the project.
+5. Add the libc.lib library from the ObjectAda distribution to the project.
+6. Build the executable using test.adb as a main procedure.
+
+
+ How to use ZLib.Ada
+
+The source files test.adb and read.adb are small demo programs that show
+the main functionality of ZLib.Ada.
+
+The routines from the package specifications are commented.

+This is a patched version of zlib modified to use
+Pentium-optimized assembly code in the deflation algorithm. The files
+changed/added by this patch are:
+
+README.586
+match.S
+
+The effectiveness of these modifications is a bit marginal, as the the
+program's bottleneck seems to be mostly L1-cache contention, for which
+there is no real way to work around without rewriting the basic
+algorithm. The speedup on average is around 5-10% (which is generally
+less than the amount of variance between subsequent executions).
+However, when used at level 9 compression, the cache contention can
+drop enough for the assembly version to achieve 10-20% speedup (and
+sometimes more, depending on the amount of overall redundancy in the
+files). Even here, though, cache contention can still be the limiting
+factor, depending on the nature of the program using the zlib library.
+This may also mean that better improvements will be seen on a Pentium
+with MMX, which suffers much less from L1-cache contention, but I have
+not yet verified this.
+
+Note that this code has been tailored for the Pentium in particular,
+and will not perform well on the Pentium Pro (due to the use of a
+partial register in the inner loop).
+
+If you are using an assembler other than GNU as, you will have to
+translate match.S to use your assembler's syntax. (Have fun.)

+ * doing two separate 8-bit accesses, as the memory is so rarely in the
+ * L1 cache.
+ *
+ * The window buffer, however, apparently spends a lot of time in the
+ * cache, and so it is faster to retrieve the word at the end of the
+ * match string with two 8-bit loads. The instructions that test the
+ * word at the beginning of the match string, however, are executed
+ * much less frequently, and there it was cheaper to use 16-bit

+
+The speedup that this patch provides varies, depending on whether the

+the default compression level, and 20-30% using -9, against a version

+ * - A bit preceding a literal or length/distance pair indicates which comes

+ * no bit reversal is needed for either the length extra bits or the distance
+ * extra bits.

+
+ TCompressionStream is write-only and strictly sequential. Reading from the

+ will raise an exception.

+ Output data is cached internally, written to the output stream only when
+ the internal output buffer is full. All pending output data is flushed
+ when the stream is destroyed.

+ The Position property returns the number of uncompressed bytes of

+ allowed. Seeking forward decompresses data until the requested position in
+ the uncompressed data has been reached. Seeking backwards, seeking relative
+ to the end of the stream, requesting the size of the stream, and writing to
+ the stream will raise an exception.

+ have been read from the stream so far.

+
+Overview
+========
+
+This directory contains an update to the ZLib interface unit,
+distributed by Borland as a Delphi supplemental component.
+
+The original ZLib unit is Copyright (c) 1997,99 Borland Corp.,
+and is based on zlib version 1.0.4. There are a series of bugs
+and security problems associated with that old zlib version, and
+we recommend the users to update their ZLib unit.
+
+
+Summary of modifications
+========================
+
+- Improved makefile, adapted to zlib version 1.2.1.
+
+- Some field types from TZStreamRec are changed from Integer to
+ Longint, for consistency with the zlib.h header, and for 64-bit
+ readiness.
+
+- The zlib_version constant is updated.
+
+- The new Z_RLE strategy has its corresponding symbolic constant.
+
+- The allocation and deallocation functions and function types
+ (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl,
+ and _malloc and _free are added as C RTL stubs. As a result,
+ the original C sources of zlib can be compiled out of the box,
+ and linked to the ZLib unit.
+
+
+Suggestions for improvements
+============================
+
+Currently, the ZLib unit provides only a limited wrapper around
+the zlib library, and much of the original zlib functionality is
+missing. Handling compressed file formats like ZIP/GZIP or PNG
+cannot be implemented without having this functionality.
+Applications that handle these formats are either using their own,
+duplicated code, or not using the ZLib unit at all.
+
+Here are a few suggestions:
+
+- Checksum class wrappers around adler32() and crc32(), similar
+ to the Java classes that implement the java.util.zip.Checksum
+ interface.
+
+- The ability to read and write raw deflate streams, without the
+ zlib stream header and trailer. Raw deflate streams are used
+ in the ZIP file format.
+
+- The ability to read and write gzip streams, used in the GZIP
+ file format, and normally produced by the gzip program.
+
+- The ability to select a different compression strategy, useful
+ to PNG and MNG image compression, and to multimedia compression
+ in general. Besides the compression level
+
+ TCompressionLevel = (clNone, clFastest, clDefault, clMax);
+
+ which, in fact, could have used the 'z' prefix and avoided
+ TColor-like symbols
+
+ TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax);
+
+ there could be a compression strategy
+
+ TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle);
+
+- ZIP and GZIP stream handling via TStreams.

+This directory contains a .Net wrapper class library for the ZLib1.dll
+
+The wrapper includes support for inflating/deflating memory buffers,
+.Net streaming wrappers for the gz streams part of zlib, and wrappers
+for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.
+
+Directory structure:
+--------------------
+
+LICENSE_1_0.txt - License file.
+readme.txt - This file.
+DotZLib.chm - Class library documentation
+DotZLib.build - NAnt build file
+DotZLib.sln - Microsoft Visual Studio 2003 solution file
+
+DotZLib\*.cs - Source files for the class library
+
+Unit tests:
+-----------
+The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
+To include unit tests in the build, define nunit before building.
+
+
+Build instructions:
+-------------------
+
+1. Using Visual Studio.Net 2003:
+ Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
+ will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
+ you are building the release or debug version of the library. Check
+ DotZLib/UnitTests.cs for instructions on how to include unit tests in the
+ build.
+
+2. Using NAnt:
+ Open a command prompt with access to the build environment and run nant
+ in the same directory as the DotZLib.build file.
+ You can define 2 properties on the nant command-line to control the build:
+ debug={true|false} to toggle between release/debug builds (default=true).
+ nunit={true|false} to include or esclude unit tests (default=true).
+ Also the target clean will remove binaries.
+ Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
+ or ./DotZLib/bin/debug, depending on whether you are building the release
+ or debug version of the library.
+
+ Examples:
+ nant -D:debug=false -D:nunit=false
+ will build a release mode version of the library without unit tests.
+ nant
+ will build a debug version of the library with unit tests
+ nant clean
+ will remove all previously built files.

+ in() and out() are the call-back input and output functions. When
+ inflateBack() needs more input, it calls in(). When inflateBack() has
+ filled the window with output, or when it completes with data in the
+ window, it calls out() to write out the data. The application must not
+ change the provided input until in() is called again or inflateBack()
+ returns. The application must not change the window/output buffer until
+ inflateBack() returns.
+
+ in() and out() are called with a descriptor parameter provided in the
+ inflateBack() call. This parameter can be a structure that provides the
+ information required to do the read or write, as well as accumulated
+ information on the input and output such as totals and check values.
+
+ in() should return zero on failure. out() should return non-zero on
+ failure. If either in() or out() fails, than inflateBack() returns a
+ Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
+ was in() or out() that caused in the error. Otherwise, inflateBack()
+ returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
+ error, or Z_MEM_ERROR if it could not allocate memory for the state.

+ bits off of the bottom. For codes where len is less than drop + curr,
+ those top drop + curr - len bits are incremented through all values to
+ fill the table with replicated entries.
+
+ root is the number of index bits for the root table. When len exceeds
+ root, sub-tables are created pointed to by the root entry with an index

+ When a new sub-table is needed, it is necessary to look ahead in the

+ counts are used for this, and so count[] is decremented as codes are
+ entered in the tables.
+
+ used keeps track of how many table entries have been allocated from the
+ provided *table space. It is checked when a LENS table is being made
+ against the space in *table, ENOUGH, minus the maximum space needed by
+ the worst case distance code, MAXD. This should never happen, but the
+ sufficiency of ENOUGH has not been proven exhaustively, hence the check.
+ This assumes that when type == LENS, bits == 9.

+ * Dec-29-2003 -- I added AMD64 inflate asm support. This version is also
+ * slightly quicker on x86 systems because, instead of using rep movsb to copy
+ * data, it uses rep movsw, which moves data in 2-byte chunks instead of single
+ * bytes. I've tested the AMD64 code on a Fedora Core 1 + the x86_64 updates
+ * from http://fedora.linux.duke.edu/fc1_x86_64
+ * which is running on an Athlon 64 3000+ / Gigabyte GA-K8VT800M system with
+ * 1GB ram. The 64-bit version is about 4% faster than the 32-bit version,
+ * when decompressing mozilla-source-1.3.tar.gz.
+ *
+ * Mar-13-2003 -- Most of this is derived from inffast.S which is derived from
+ * the gcc -S output of zlib-1.2.0/inffast.c. Zlib-1.2.0 is in beta release at
+ * the moment. I have successfully compiled and tested this code with gcc2.96,
+ * gcc3.2, icc5.0, msvc6.0. It is very close to the speed of inffast.S
+ * compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX
+ * enabled. I will attempt to merge the MMX code into this version. Newer
+ * versions of this and inffast.S can be found at

+/*
+ Decode literal, length, and distance codes and write out the resulting
+ literal and match bytes until either not enough input or output is
+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for
+ example, a 16K input buffer and a 64K output buffer, more than 95% of the
+ inflate execution time is spent in this routine.
+
+ Entry assumptions:
+
+ state->mode == LEN
+ strm->avail_in >= 6
+ strm->avail_out >= 258
+ start >= strm->avail_out
+ state->bits < 8
+
+ On return, state->mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm->avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm->avail_out >= 258 for each loop to avoid checking for
+ output space.

+ * inffast.S is a hand tuned assembler version of:
+ *
+ * inffast.c -- fast decoding
+ * Copyright (C) 1995-2003 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ *
+ * Copyright (C) 2003 Chris Anderson <christop@charm.net>
+ * Please use the copyright conditions above.
+ *
+ * This version (Jan-23-2003) of inflate_fast was coded and tested under
+ * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution. On that
+ * machine, I found that gzip style archives decompressed about 20% faster than
+ * the gcc-3.2 -O3 -fomit-frame-pointer compiled version. Your results will
+ * depend on how large of a buffer is used for z_stream.next_in & next_out
+ * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in
+ * stream processing I/O and crc32/addler32. In my case, this routine used
+ * 70% of the cpu time and crc32 used 20%.
+ *
+ * I am confident that this version will work in the general case, but I have
+ * not tested a wide variety of datasets or a wide variety of platforms.
+ *
+ * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating.
+ * It should be a runtime flag instead of compile time flag...
+ *
+ * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction.
+ * With -DUSE_MMX, only MMX code is compiled. With -DNO_MMX, only non-MMX code
+ * is compiled. Without either option, runtime detection is enabled. Runtime
+ * detection should work on all modern cpus and the recomended algorithm (flip
+ * ID bit on eflags and then use the cpuid instruction) is used in many
+ * multimedia applications. Tested under win2k with gcc-2.95 and gas-2.12
+ * distributed with cygwin3. Compiling with gcc-2.95 -c inffast.S -o
+ * inffast.obj generates a COFF object which can then be linked with MSVC++
+ * compiled code. Tested under FreeBSD 4.7 with gcc-2.95.
+ *
+ * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and
+ * slower than compiler generated code). Adjusted cpuid check to use the MMX
+ * code only for Pentiums < P4 until I have more data on the P4. Speed
+ * improvment is only about 15% on the Athlon when compared with code generated
+ * with MSVC++. Not sure yet, but I think the P4 will also be slower using the
+ * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and
+ * have less latency than MMX ops. Added code to buffer the last 11 bytes of
+ * the input stream since the MMX code grabs bits in chunks of 32, which
+ * differs from the inffast.c algorithm. I don't think there would have been
+ * read overruns where a page boundary was crossed (a segfault), but there
+ * could have been overruns when next_in ends on unaligned memory (unintialized
+ * memory read).
+ *
+ * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX. I created a C
+ * version of the non-MMX code so that it doesn't depend on zstrm and zstate
+ * structure offsets which are hard coded in this file. This was last tested
+ * with zlib-1.2.0 which is currently in beta testing, newer versions of this
+ * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and
+ * http://www.charm.net/~christop/zlib/

+These classes provide a C++ stream interface to the zlib library. It allows you
+to do things like:
+
+ gzofstream outf("blah.gz");
+ outf << "These go into the gzip file " << 123 << endl;
+
+It does this by deriving a specialized stream buffer for gzipped files, which is
+the way Stroustrup would have done it. :->
+
+The gzifstream and gzofstream classes were originally written by Kevin Ruland
+and made available in the zlib contrib/iostream directory. The older version still
+compiles under gcc 2.xx, but not under gcc 3.xx, which sparked the development of
+this version.
+
+The new classes are as standard-compliant as possible, closely following the
+approach of the standard library's fstream classes. It compiles under gcc versions
+3.2 and 3.3, but not under gcc 2.xx. This is mainly due to changes in the standard
+library naming scheme. The new version of gzifstream/gzofstream/gzfilebuf differs
+from the previous one in the following respects:
+- added showmanyc
+- added setbuf, with support for unbuffered output via setbuf(0,0)
+- a few bug fixes of stream behavior
+- gzipped output file opened with default compression level instead of maximum level
+- setcompressionlevel()/strategy() members replaced by single setcompression()
+
+The code is provided "as is", with the permission to use, copy, modify, distribute
+and sell it for any purpose without fee.

+Possible upgrades to gzfilebuf:
+
+- The ability to do putback (e.g. putbackfail)
+
+- The ability to seek (zlib supports this, but could be slow/tricky)
+
+- Simultaneous read/write access (does it make sense?)
+
+- Support for ios_base::ate open mode
+
+- Locale support?
+
+- Check public interface to see which calls give problems
+ (due to dependence on library internals)

+- Override operator<<(ostream&, gzfilebuf*) to allow direct copying

+/*
+ Decode literal, length, and distance codes and write out the resulting
+ literal and match bytes until either not enough input or output is
+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for
+ example, a 16K input buffer and a 64K output buffer, more than 95% of the
+ inflate execution time is spent in this routine.
+
+ Entry assumptions:
+
+ state->mode == LEN
+ strm->avail_in >= 6
+ strm->avail_out >= 258
+ start >= strm->avail_out
+ state->bits < 8
+
+ On return, state->mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm->avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm->avail_out >= 258 for each loop to avoid checking for
+ output space.

+Summary
+-------
+This directory contains ASM implementations of the functions
+longest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),
+for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.
+
+gvmat64.asm is written by Gilles Vollant (2005), by using Brian Raiter 686/32 bits
+ assembly optimized version from Jean-loup Gailly original longest_match function
+
+inffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing
+ original function from Mark Adler
+
+Use instructions
+----------------
+Copy these files into the zlib source directory.
+
+define ASMV and ASMINF in your project. Include inffas8664.c in your source tree,
+and inffasx64.obj and gvmat64.obj as object to link.
+
+
+Build instructions
+------------------

+; and in VC++2003 toolkit at http://msdn.microsoft.com/visualc/vctoolkit2003/
+;
+; this file contain two implementation of longest_match
+;
+; longest_match_7fff : written 1996 by Gilles Vollant optimized for
+; first Pentium. Assume s->w_mask == 0x7fff
+; longest_match_686 : written by Brian raiter (1998), optimized for Pentium Pro
+;
+; for using an seembly version of longest_match, you need define ASMV in project
+; There is two way in using gvmat32.asm
+;
+; A) Suggested method
+; if you want include both longest_match_7fff and longest_match_686
+; compile the asm file running
+; ml /coff /Zi /Flgvmat32.lst /c gvmat32.asm
+; and include gvmat32c.c in your project
+; if you have an old cpu (386,486 or first Pentium) and s->w_mask==0x7fff,
+; longest_match_7fff will be used
+; if you have a more modern CPU (Pentium Pro, II and higher)
+; longest_match_686 will be used
+; on old cpu with s->w_mask!=0x7fff, longest_match_686 will be used,
+; but this is not a sitation you'll find often
+;
+; B) Alternative
+; if you are not interresed in old cpu performance and want the smaller
+; binaries possible
+;
+; compile the asm file running
+; ml /coff /Zi /c /Flgvmat32.lst /DNOOLDPENTIUMCODE gvmat32.asm
+; and do not include gvmat32c.c in your project (ou define also
+; NOOLDPENTIUMCODE)
+;
+; note : as I known, longest_match_686 is very faster than longest_match_7fff
+; on pentium Pro/II/III, faster (but less) in P4, but it seem
+; longest_match_7fff can be faster (very very litte) on AMD Athlon64/K8
+;
+; see below : zlib1222add must be adjuster if you use a zlib version < 1.2.2.2

+ whole source package can be freely distributed, including from the USA.
+ (Prior to January 2000, re-export from the US was a violation of US law.)
+
+ This encryption code is a direct transcription of the algorithm from
+ Roger Schlafly, described by Phil Katz in the file appnote.txt. This
+ file (appnote.txt) is distributed with the PKZIP program (even in the
+ version without encryption capabilities).
+
+ If you don't need crypting in your application, just define symbols
+ NOCRYPT and NOUNCRYPT.
+
+ This code support the "Traditional PKWARE Encryption".
+
+ The new AES encryption added on Zip format by Winzip (see the page
+ http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
+ Encryption is not supported.

+readme.txt this file
+
+
+Compatibility notes
+===================
+
+- Although the name "zlib" would have been more normal for the
+ zlibpas unit, this name is already taken by Borland's ZLib unit.
+ This is somehow unfortunate, because that unit is not a genuine
+ interface to the full-fledged zlib functionality, but a suite of
+ class wrappers around zlib streams. Other essential features,
+ such as checksums, are missing.
+ It would have been more appropriate for that unit to have a name
+ like "ZStreams", or something similar.
+
+- The C and zlib-supplied types int, uInt, long, uLong, etc. are
+ translated directly into Pascal types of similar sizes (Integer,
+ LongInt, etc.), to avoid namespace pollution. In particular,
+ there is no conversion of unsigned int into a Pascal unsigned
+ integer. The Word type is non-portable and has the same size
+ (16 bits) both in a 16-bit and in a 32-bit environment, unlike
+ Integer. Even if there is a 32-bit Cardinal type, there is no
+ real need for unsigned int in zlib under a 32-bit environment.
+
+- Except for the callbacks, the zlib function interfaces are
+ assuming the calling convention normally used in Pascal
+ (__pascal for DOS and Windows16, __fastcall for Windows32).
+ Since the cdecl keyword is used, the old Turbo Pascal does
+ not work with this interface.
+
+- The gz* function interfaces are not translated, to avoid
+ interfacing problems with the C runtime library. Besides,
+ gzprintf(gzFile file, const char *format, ...)
+ cannot be translated into Pascal.

+Puff -- A Simple Inflate
+3 Mar 2003
+Mark Adler
+madler@alumni.caltech.edu
+
+What this is --
+
+puff.c provides the routine puff() to decompress the deflate data format. It
+does so more slowly than zlib, but the code is about one-fifth the size of the
+inflate code in zlib, and written to be very easy to read.
+
+Why I wrote this --
+
+puff.c was written to document the deflate format unambiguously, by virtue of
+being working C code. It is meant to supplement RFC 1951, which formally
+describes the deflate format. I have received many questions on details of the
+deflate format, and I hope that reading this code will answer those questions.
+puff.c is heavily commented with details of the deflate format, especially
+those little nooks and cranies of the format that might not be obvious from a
+specification.
+
+puff.c may also be useful in applications where code size or memory usage is a
+very limited resource, and speed is not as important.
+
+How to use it --
+
+Well, most likely you should just be reading puff.c and using zlib for actual
+applications, but if you must ...
+
+Include puff.h in your code, which provides this prototype:
+
+int puff(unsigned char *dest, /* pointer to destination pointer */
+ unsigned long *destlen, /* amount of output space */
+ unsigned char *source, /* pointer to source data pointer */
+ unsigned long *sourcelen); /* amount of input available */
+
+Then you can call puff() to decompress a deflate stream that is in memory in
+its entirety at source, to a sufficiently sized block of memory for the
+decompressed data at dest. puff() is the only external symbol in puff.c The
+only C library functions that puff.c needs are setjmp() and longjmp(), which
+are used to simplify error checking in the code to improve readabilty. puff.c
+does no memory allocation, and uses less than 2K bytes off of the stack.
+
+If destlen is not enough space for the uncompressed data, then inflate will
+return an error without writing more than destlen bytes. Note that this means
+that in order to decompress the deflate data successfully, you need to know
+the size of the uncompressed data ahead of time.
+
+If needed, puff() can determine the size of the uncompressed data with no
+output space. This is done by passing dest equal to (unsigned char *)0. Then
+the initial value of *destlen is ignored and *destlen is set to the length of
+the uncompressed data. So if the size of the uncompressed data is not known,
+then two passes of puff() can be used--first to determine the size, and second
+to do the actual inflation after allocating the appropriate memory. Not
+pretty, but it works. (This is one of the reasons you should be using zlib.)
+
+The deflate format is self-terminating. If the deflate stream does not end
+in *sourcelen bytes, puff() will return an error without reading at or past
+endsource.
+
+On return, *sourcelen is updated to the amount of input data consumed, and
+*destlen is updated to the size of the uncompressed data. See the comments
+in puff.c for the possible return codes for puff().

+ * For conditions of distribution and use, see copyright notice in puff.h
+ * version 1.8, 9 Jan 2004
+ *
+ * puff.c is a simple inflate written to be an unambiguous way to specify the
+ * deflate format. It is not written for speed but rather simplicity. As a
+ * side benefit, this code might actually be useful when small code is more
+ * important than speed, such as bootstrap applications. For typical deflate
+ * data, zlib's inflate() is about four times as fast as puff(). zlib's
+ * inflate compiles to around 20K on my machine, whereas puff.c compiles to
+ * around 4K on my machine (a PowerPC using GNU cc). If the faster decode()
+ * function here is used, then puff() is only twice as slow as zlib's
+ * inflate().
+ *
+ * All dynamically allocated memory comes from the stack. The stack required
+ * is less than 2K bytes. This code is compatible with 16-bit int's and
+ * assumes that long's are at least 32 bits. puff.c uses the short data type,
+ * assumed to be 16 bits, for arrays in order to to conserve memory. The code
+ * works whether integers are stored big endian or little endian.
+ *
+ * In the comments below are "Format notes" that describe the inflate process
+ * and document some of the less obvious aspects of the format. This source
+ * code is meant to supplement RFC 1951, which formally describes the deflate
+ * format:
+ *

+ * Decode literal/length and distance codes until an end-of-block code.
+ *
+ * Format notes:
+ *
+ * - Compressed data that is after the block type if fixed or after the code
+ * description if dynamic is a combination of literals and length/distance
+ * pairs terminated by and end-of-block code. Literals are simply Huffman
+ * coded bytes. A length/distance pair is a coded length followed by a
+ * coded distance to represent a string that occurs earlier in the
+ * uncompressed data that occurs again at the current location.
+ *
+ * - Literals, lengths, and the end-of-block code are combined into a single
+ * code of up to 286 symbols. They are 256 literals (0..255), 29 length
+ * symbols (257..285), and the end-of-block symbol (256).
+ *
+ * - There are 256 possible lengths (3..258), and so 29 symbols are not enough
+ * to represent all of those. Lengths 3..10 and 258 are in fact represented
+ * by just a length symbol. Lengths 11..257 are represented as a symbol and
+ * some number of extra bits that are added as an integer to the base length
+ * of the length symbol. The number of extra bits is determined by the base
+ * length symbol. These are in the static arrays below, lens[] for the base
+ * lengths and lext[] for the corresponding number of extra bits.
+ *
+ * - The reason that 258 gets its own symbol is that the longest length is used
+ * often in highly redundant files. Note that 258 can also be coded as the
+ * base value 227 plus the maximum extra value of 31. While a good deflate
+ * should never do this, it is not an error, and should be decoded properly.
+ *
+ * - If a length is decoded, including its extra bits if any, then it is
+ * followed a distance code. There are up to 30 distance symbols. Again
+ * there are many more possible distances (1..32768), so extra bits are added
+ * to a base value represented by the symbol. The distances 1..4 get their
+ * own symbol, but the rest require extra bits. The base distances and
+ * corresponding number of extra bits are below in the static arrays dist[]
+ * and dext[].
+ *
+ * - Literal bytes are simply written to the output. A length/distance pair is
+ * an instruction to copy previously uncompressed bytes to the output. The
+ * copy is from distance bytes back in the output stream, copying for length
+ * bytes.
+ *
+ * - Distances pointing before the beginning of the output data are not
+ * permitted.
+ *
+ * - Overlapped copies, where the length is greater than the distance, are
+ * allowed and common. For example, a distance of one and a length of 258
+ * simply copies the last byte 258 times. A distance of four and a length of
+ * twelve copies the last four bytes three times. A simple forward copy
+ * ignoring whether the length is greater than the distance or not implements
+ * this correctly. You should not use memcpy() since its behavior is not
+ * defined for overlapped arrays. You should not use memmove() or bcopy()
+ * since though their behavior -is- defined for overlapping arrays, it is
+ * defined to do the wrong thing in this case.

+ * Process a dynamic codes block.
+ *
+ * Format notes:
+ *
+ * - A dynamic block starts with a description of the literal/length and
+ * distance codes for that block. New dynamic blocks allow the compressor to
+ * rapidly adapt to changing data with new codes optimized for that data.
+ *
+ * - The codes used by the deflate format are "canonical", which means that
+ * the actual bits of the codes are generated in an unambiguous way simply
+ * from the number of bits in each code. Therefore the code descriptions
+ * are simply a list of code lengths for each symbol.
+ *
+ * - The code lengths are stored in order for the symbols, so lengths are
+ * provided for each of the literal/length symbols, and for each of the
+ * distance symbols.
+ *
+ * - If a symbol is not used in the block, this is represented by a zero as
+ * as the code length. This does not mean a zero-length code, but rather
+ * that no code should be created for this symbol. There is no way in the
+ * deflate format to represent a zero-length code.
+ *
+ * - The maximum number of bits in a code is 15, so the possible lengths for
+ * any code are 1..15.
+ *
+ * - The fact that a length of zero is not permitted for a code has an
+ * interesting consequence. Normally if only one symbol is used for a given
+ * code, then in fact that code could be represented with zero bits. However
+ * in deflate, that code has to be at least one bit. So for example, if
+ * only a single distance base symbol appears in a block, then it will be
+ * represented by a single code of length one, in particular one 0 bit. This
+ * is an incomplete code, since if a 1 bit is received, it has no meaning,
+ * and should result in an error. So incomplete distance codes of one symbol
+ * should be permitted, and the receipt of invalid codes should be handled.
+ *
+ * - It is also possible to have a single literal/length code, but that code
+ * must be the end-of-block code, since every dynamic block has one. This
+ * is not the most efficient way to create an empty block (an empty fixed
+ * block is fewer bits), but it is allowed by the format. So incomplete
+ * literal/length codes of one symbol should also be permitted.
+ *
+ * - If there are only literal codes and no lengths, then there are no distance
+ * codes. This is represented by one distance code with zero bits.
+ *
+ * - The list of up to 286 length/literal lengths and up to 30 distance lengths
+ * are themselves compressed using Huffman codes and run-length encoding. In
+ * the list of code lengths, a 0 symbol means no code, a 1..15 symbol means
+ * that length, and the symbols 16, 17, and 18 are run-length instructions.
+ * Each of 16, 17, and 18 are follwed by extra bits to define the length of
+ * the run. 16 copies the last length 3 to 6 times. 17 represents 3 to 10
+ * zero lengths, and 18 represents 11 to 138 zero lengths. Unused symbols
+ * are common, hence the special coding for zero lengths.
+ *
+ * - The symbols for 0..18 are Huffman coded, and so that code must be
+ * described first. This is simply a sequence of up to 19 three-bit values
+ * representing no code (0) or the code length for that symbol (1..7).
+ *
+ * - A dynamic block starts with three fixed-size counts from which is computed
+ * the number of literal/length code lengths, the number of distance code
+ * lengths, and the number of code length code lengths (ok, you come up with
+ * a better name!) in the code descriptions. For the literal/length and
+ * distance codes, lengths after those provided are considered zero, i.e. no
+ * code. The code length code lengths are received in a permuted order (see
+ * the order[] array below) to make a short code length code length list more
+ * likely. As it turns out, very short and very long codes are less likely
+ * to be seen in a dynamic code description, hence what may appear initially
+ * to be a peculiar ordering.
+ *
+ * - Given the number of literal/length code lengths (nlen) and distance code
+ * lengths (ndist), then they are treated as one long list of nlen + ndist
+ * code lengths. Therefore run-length coding can and often does cross the
+ * boundary between the two sets of lengths.
+ *
+ * - So to summarize, the code description at the start of a dynamic block is
+ * three counts for the number of code lengths for the literal/length codes,
+ * the distance codes, and the code length codes. This is followed by the
+ * code length code lengths, three bits each. This is used to construct the
+ * code length code which is used to read the remainder of the lengths. Then
+ * the literal/length code lengths and distance lengths are read as a single
+ * set of lengths using the code length codes. Codes are constructed from
+ * the resulting two sets of lengths, and then finally you can start
+ * decoding actual compressed data in the block.
+ *
+ * - For reference, a "typical" size for the code description in a dynamic
+ * block is around 80 bytes.

+Building instructions for the DLL versions of Zlib 1.2.3
+========================================================
+
+This directory contains projects that build zlib and minizip using
+Microsoft Visual C++ 7.0/7.1, and Visual C++ .
+
+You don't need to build these projects yourself. You can download the
+binaries from:
+ http://www.winimage.com/zLibDll
+
+More information can be found at this site.
+
+
+Build instructions for Visual Studio 7.x (32 bits)
+--------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- Download the crtdll library from
+ http://www.winimage.com/zLibDll/crtdll.zip
+ Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc7.
+- Open contrib\vstudio\vc7\zlibvc.sln with Microsoft Visual C++ 7.x
+ (Visual Studio .Net 2002 or 2003).
+
+Build instructions for Visual Studio 2005 (32 bits or 64 bits)
+--------------------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- For 32 bits only: download the crtdll library from
+ http://www.winimage.com/zLibDll/crtdll.zip
+ Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc8.
+- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
+
+Build instructions for Visual Studio 2005 64 bits, PSDK compiler
+----------------------------------------------------------------
+at the time of writing this text file, Visual Studio 2005 (and
+ Microsoft Visual C++ 8.0) is on the beta 2 stage.
+Using you can get the free 64 bits compiler from Platform SDK,
+ which is NOT a beta, and compile using the Visual studio 2005 IDE
+see http://www.winimage.com/misc/sdk64onvs2005/ for instruction
+
+- Uncompress current zlib, including all contrib/* files
+- start Visual Studio 2005 from a platform SDK command prompt, using
+ the /useenv switch
+- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
+
+
+Important
+---------
+- To use zlibwapi.dll in your application, you must define the
+ macro ZLIB_WINAPI when compiling your application's source files.
+
+
+Additional notes
+----------------
+- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
+ by Gilles Vollant from the zlib 1.1.x sources, and distributed at
+ http://www.winimage.com/zLibDll
+ It uses the WINAPI calling convention for the exported functions, and
+ includes the minizip functionality. If your application needs that
+ particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
+
+- The new DLL was renamed because there exist several incompatible
+ versions of zlib.dll on the Internet.
+
+- There is also an official DLL build of zlib, named zlib1.dll. This one
+ is exporting the functions using the CDECL convention. See the file
+ win32\DLL_FAQ.txt found in this zlib distribution.
+
+- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
+ has a slightly different effect. To avoid compatibility problems, do
+ not define it here.
+

+This directory contains examples of the use of zlib.
+
+fitblk.c
+ compress just enough input to nearly fill a requested output size
+ - zlib isn't designed to do this, but fitblk does it anyway
+
+gun.c
+ uncompress a gzip file
+ - illustrates the use of inflateBack() for high speed file-to-file
+ decompression using call-back functions
+ - is approximately twice as fast as gzip -d
+ - also provides Unix uncompress functionality, again twice as fast
+
+gzappend.c
+ append to a gzip file
+ - illustrates the use of the Z_BLOCK flush parameter for inflate()
+ - illustrates the use of deflatePrime() to start at any bit
+
+gzjoin.c
+ join gzip files without recalculating the crc or recompressing
+ - illustrates the use of the Z_BLOCK flush parameter for inflate()
+ - illustrates the use of crc32_combine()
+
+gzlog.c
+gzlog.h
+ efficiently maintain a message log file in gzip format
+ - illustrates use of raw deflate and Z_SYNC_FLUSH
+ - illustrates use of gzip header extra field
+
+zlib_how.html
+ painfully comprehensive description of zpipe.c (see below)
+ - describes in excruciating detail the use of deflate() and inflate()
+
+zpipe.c
+ reads and writes zlib streams from stdin to stdout
+ - illustrates the proper use of deflate() and inflate()
+ - deeply commented in zlib_how.html (see above)
+
+zran.c
+ index a zlib or gzip stream and randomly access it
+ - illustrates the use of Z_BLOCK, inflatePrime(), and
+ inflateSetDictionary() to provide random access

+/* fitblk.c: example of fitting compressed output to a specified size
+ Not copyrighted -- provided to the public domain
+ Version 1.1 25 November 2004 Mark Adler */
+
+/* Version history:
+ 1.0 24 Nov 2004 First version
+ 1.1 25 Nov 2004 Change deflateInit2() to deflateInit()
+ Use fixed-size, stack-allocated raw buffers
+ Simplify code moving compression to subroutines
+ Use assert() for internal errors
+ Add detailed description of approach
+ */
+
+/* Approach to just fitting a requested compressed size:
+
+ fitblk performs three compression passes on a portion of the input
+ data in order to determine how much of that input will compress to
+ nearly the requested output block size. The first pass generates
+ enough deflate blocks to produce output to fill the requested
+ output size plus a specfied excess amount (see the EXCESS define
+ below). The last deflate block may go quite a bit past that, but
+ is discarded. The second pass decompresses and recompresses just
+ the compressed data that fit in the requested plus excess sized
+ buffer. The deflate process is terminated after that amount of
+ input, which is less than the amount consumed on the first pass.
+ The last deflate block of the result will be of a comparable size
+ to the final product, so that the header for that deflate block and
+ the compression ratio for that block will be about the same as in
+ the final product. The third compression pass decompresses the
+ result of the second step, but only the compressed data up to the
+ requested size minus an amount to allow the compressed stream to
+ complete (see the MARGIN define below). That will result in a
+ final compressed stream whose length is less than or equal to the
+ requested size. Assuming sufficient input and a requested size
+ greater than a few hundred bytes, the shortfall will typically be
+ less than ten bytes.
+
+ If the input is short enough that the first compression completes
+ before filling the requested output size, then that compressed
+ stream is return with no recompression.
+
+ EXCESS is chosen to be just greater than the shortfall seen in a
+ two pass approach similar to the above. That shortfall is due to
+ the last deflate block compressing more efficiently with a smaller
+ header on the second pass. EXCESS is set to be large enough so
+ that there is enough uncompressed data for the second pass to fill
+ out the requested size, and small enough so that the final deflate
+ block of the second pass will be close in size to the final deflate
+ block of the third and final pass. MARGIN is chosen to be just
+ large enough to assure that the final compression has enough room
+ to complete in all cases.

+ gun [ -t ] [ name ... ]
+
+ decompresses the data in the named gzip files. If no arguments are given,
+ gun will decompress from stdin to stdout. The names must end in .gz, -gz,
+ .z, -z, _z, or .Z. The uncompressed data will be written to a file name
+ with the suffix stripped. On success, the original file is deleted. On
+ failure, the output file is deleted. For most failures, the command will
+ continue to process the remaining names on the command line. A memory
+ allocation failure will abort the command. If -t is specified, then the
+ listed files or stdin will be tested as gzip files for integrity (without
+ checking for a proper suffix), no output will be written, and no files
+ will be deleted.
+
+ Like gzip, gun allows concatenated gzip streams and will decompress them,
+ writing all of the uncompressed data to the output. Unlike gzip, gun allows
+ an empty file on input, and will produce no error writing an empty output
+ file.
+
+ gun will also decompress files made by Unix compress, which uses LZW
+ compression. These files are automatically detected by virtue of their
+ magic header bytes. Since the end of Unix compress stream is marked by the
+ end-of-file, they cannot be concantenated. If a Unix compress stream is
+ encountered in an input file, it is the last stream in that file.
+
+ Like gunzip and uncompress, the file attributes of the orignal compressed
+ file are maintained in the final uncompressed file, to the extent that the
+ user permissions allow it.
+
+ On my Mac OS X PowerPC G4, gun is almost twice as fast as gunzip (version
+ 1.2.4) is on the same file, when gun is linked with zlib 1.2.2. Also the
+ LZW decompression provided by gun is about twice as fast as the standard
+ Unix uncompress command.

+/*
+ gzappend takes a gzip file and appends to it, compressing files from the
+ command line or data from stdin. The gzip file is written to directly, to
+ avoid copying that file, in case it's large. Note that this results in the
+ unfriendly behavior that if gzappend fails, the gzip file is corrupted.
+
+ This program was written to illustrate the use of the new Z_BLOCK option of
+ zlib 1.2.x's inflate() function. This option returns from inflate() at each
+ block boundary to facilitate locating and modifying the last block bit at
+ the start of the final deflate block. Also whether using Z_BLOCK or not,
+ another required feature of zlib 1.2.x is that inflate() now provides the
+ number of unusued bits in the last input byte used. gzappend will not work
+ with versions of zlib earlier than 1.2.1.
+
+ gzappend first decompresses the gzip file internally, discarding all but
+ the last 32K of uncompressed data, and noting the location of the last block
+ bit and the number of unused bits in the last byte of the compressed data.
+ The gzip trailer containing the CRC-32 and length of the uncompressed data
+ is verified. This trailer will be later overwritten.
+
+ Then the last block bit is cleared by seeking back in the file and rewriting
+ the byte that contains it. Seeking forward, the last byte of the compressed
+ data is saved along with the number of unused bits to initialize deflate.
+
+ A deflate process is initialized, using the last 32K of the uncompressed
+ data from the gzip file to initialize the dictionary. If the total
+ uncompressed data was less than 32K, then all of it is used to initialize
+ the dictionary. The deflate output bit buffer is also initialized with the
+ last bits from the original deflate stream. From here on, the data to
+ append is simply compressed using deflate, and written to the gzip file.
+ When that is complete, the new CRC-32 and uncompressed length are written
+ as the trailer of the gzip file.

+ gzjoin takes one or more gzip files on the command line and writes out a
+ single gzip file that will uncompress to the concatenation of the
+ uncompressed data from the individual gzip files. gzjoin does this without
+ having to recompress any of the data and without having to calculate a new
+ crc32 for the concatenated uncompressed data. gzjoin does however have to
+ decompress all of the input data in order to find the bits in the compressed
+ data that need to be modified to concatenate the streams.
+
+ gzjoin does not do an integrity check on the input gzip files other than
+ checking the gzip header and decompressing the compressed data. They are
+ otherwise assumed to be complete and correct.
+
+ Each joint between gzip files removes at least 18 bytes of previous trailer
+ and subsequent header, and inserts an average of about three bytes to the
+ compressed data in order to connect the streams. The output gzip file
+ has a minimal ten-byte gzip header with no file name or modification time.
+
+ This program was written to illustrate the use of the Z_BLOCK option of
+ inflate() and the crc32_combine() function. gzjoin will not compile with
+ versions of zlib earlier than 1.2.3.

+We often get questions about how the <tt>deflate()</tt> and <tt>inflate()</tt> functions should be used.
+Users wonder when they should provide more input, when they should use more output,
+what to do with a <tt>Z_BUF_ERROR</tt>, how to make sure the process terminates properly, and
+so on. So for those who have read <tt>zlib.h</tt> (a few times), and
+would like further edification, below is an annotated example in C of simple routines to compress and decompress
+from an input file to an output file using <tt>deflate()</tt> and <tt>inflate()</tt> respectively. The
+annotations are interspersed between lines of the code. So please read between the lines.
+We hope this helps explain some of the intricacies of <em>zlib</em>.

+<tt>have</tt> is the amount of data returned from <tt>deflate()</tt>. The <tt>strm</tt> structure

+The first thing we do is to initialize the <em>zlib</em> state for compression using
+<tt>deflateInit()</tt>. This must be done before the first use of <tt>deflate()</tt>.
+The <tt>zalloc</tt>, <tt>zfree</tt>, and <tt>opaque</tt> fields in the <tt>strm</tt>
+structure must be initialized before calling <tt>deflateInit()</tt>. Here they are
+set to the <em>zlib</em> constant <tt>Z_NULL</tt> to request that <em>zlib</em> use
+the default memory allocation routines. An application may also choose to provide
+custom memory allocation routines here. <tt>deflateInit()</tt> will allocate on the
+order of 256K bytes for the internal state.
+(See <a href="zlib_tech.html"><em>zlib Technical Details</em></a>.)
+<p>
+<tt>deflateInit()</tt> is called with a pointer to the structure to be initialized and
+the compression level, which is an integer in the range of -1 to 9. Lower compression
+levels result in faster execution, but less compression. Higher levels result in
+greater compression, but slower execution. The <em>zlib</em> constant Z_DEFAULT_COMPRESSION,
+equal to -1,
+provides a good compromise between compression and speed and is equivalent to level 6.
+Level 0 actually does no compression at all, and in fact expands the data slightly to produce
+the <em>zlib</em> format (it is not a byte-for-byte copy of the input).
+More advanced applications of <em>zlib</em>
+may use <tt>deflateInit2()</tt> here instead. Such an application may want to reduce how
+much memory will be used, at some price in compression. Or it may need to request a
+<em>gzip</em> header and trailer instead of a <em>zlib</em> header and trailer, or raw
+encoding with no header or trailer at all.
+<p>
+We must check the return value of <tt>deflateInit()</tt> against the <em>zlib</em> constant
+<tt>Z_OK</tt> to make sure that it was able to
+allocate memory for the internal state, and that the provided arguments were valid.
+<tt>deflateInit()</tt> will also check that the version of <em>zlib</em> that the <tt>zlib.h</tt>
+file came from matches the version of <em>zlib</em> actually linked with the program. This
+is especially important for environments in which <em>zlib</em> is a shared library.
+<p>
+Note that an application can initialize multiple, independent <em>zlib</em> streams, which can
+operate in parallel. The state information maintained in the structure allows the <em>zlib</em>
+routines to be reentrant.

+</b></pre><!-- -->
+With the pleasantries out of the way, now we can get down to business. The outer <tt>do</tt>-loop
+reads all of the input file and exits at the bottom of the loop once end-of-file is reached.
+This loop contains the only call of <tt>deflate()</tt>. So we must make sure that all of the
+input data has been processed and that all of the output data has been generated and consumed
+before we fall out of the loop at the bottom.
+<pre><b>
+ /* compress until end of file */
+ do {
+</b></pre>
+We start off by reading data from the input file. The number of bytes read is put directly
+into <tt>avail_in</tt>, and a pointer to those bytes is put into <tt>next_in</tt>. We also
+check to see if end-of-file on the input has been reached. If we are at the end of file, then <tt>flush</tt> is set to the
+<em>zlib</em> constant <tt>Z_FINISH</tt>, which is later passed to <tt>deflate()</tt> to
+indicate that this is the last chunk of input data to compress. We need to use <tt>feof()</tt>
+to check for end-of-file as opposed to seeing if fewer than <tt>CHUNK</tt> bytes have been read. The
+reason is that if the input file length is an exact multiple of <tt>CHUNK</tt>, we will miss
+the fact that we got to the end-of-file, and not know to tell <tt>deflate()</tt> to finish
+up the compressed stream. If we are not yet at the end of the input, then the <em>zlib</em>
+constant <tt>Z_NO_FLUSH</tt> will be passed to <tt>deflate</tt> to indicate that we are still
+in the middle of the uncompressed data.
+<p>
+If there is an error in reading from the input file, the process is aborted with
+<tt>deflateEnd()</tt> being called to free the allocated <em>zlib</em> state before returning
+the error. We wouldn't want a memory leak, now would we? <tt>deflateEnd()</tt> can be called
+at any time after the state has been initialized. Once that's done, <tt>deflateInit()</tt> (or
+<tt>deflateInit2()</tt>) would have to be called to start a new compression process. There is
+no point here in checking the <tt>deflateEnd()</tt> return code. The deallocation can't fail.
+<pre><b>
+ strm.avail_in = fread(in, 1, CHUNK, source);
+ if (ferror(source)) {
+ (void)deflateEnd(&amp;strm);
+ return Z_ERRNO;
+ }
+ flush = feof(source) ? Z_FINISH : Z_NO_FLUSH;
+ strm.next_in = in;
+</b></pre><!-- -->
+The inner <tt>do</tt>-loop passes our chunk of input data to <tt>deflate()</tt>, and then
+keeps calling <tt>deflate()</tt> until it is done producing output. Once there is no more
+new output, <tt>deflate()</tt> is guaranteed to have consumed all of the input, i.e.,
+<tt>avail_in</tt> will be zero.
+<pre><b>
+ /* run deflate() on input until output buffer not full, finish
+ compression if all of source has been read in */
+ do {
+</b></pre>
+Output space is provided to <tt>deflate()</tt> by setting <tt>avail_out</tt> to the number
+of available output bytes and <tt>next_out</tt> to a pointer to that space.
+<pre><b>
+ strm.avail_out = CHUNK;
+ strm.next_out = out;
+</b></pre>
+Now we call the compression engine itself, <tt>deflate()</tt>. It takes as many of the
+<tt>avail_in</tt> bytes at <tt>next_in</tt> as it can process, and writes as many as
+<tt>avail_out</tt> bytes to <tt>next_out</tt>. Those counters and pointers are then
+updated past the input data consumed and the output data written. It is the amount of
+output space available that may limit how much input is consumed.
+Hence the inner loop to make sure that
+all of the input is consumed by providing more output space each time. Since <tt>avail_in</tt>
+and <tt>next_in</tt> are updated by <tt>deflate()</tt>, we don't have to mess with those
+between <tt>deflate()</tt> calls until it's all used up.
+<p>
+The parameters to <tt>deflate()</tt> are a pointer to the <tt>strm</tt> structure containing
+the input and output information and the internal compression engine state, and a parameter
+indicating whether and how to flush data to the output. Normally <tt>deflate</tt> will consume
+several K bytes of input data before producing any output (except for the header), in order
+to accumulate statistics on the data for optimum compression. It will then put out a burst of
+compressed data, and proceed to consume more input before the next burst. Eventually,
+<tt>deflate()</tt>
+must be told to terminate the stream, complete the compression with provided input data, and
+write out the trailer check value. <tt>deflate()</tt> will continue to compress normally as long
+as the flush parameter is <tt>Z_NO_FLUSH</tt>. Once the <tt>Z_FINISH</tt> parameter is provided,
+<tt>deflate()</tt> will begin to complete the compressed output stream. However depending on how
+much output space is provided, <tt>deflate()</tt> may have to be called several times until it
+has provided the complete compressed stream, even after it has consumed all of the input. The flush
+parameter must continue to be <tt>Z_FINISH</tt> for those subsequent calls.
+<p>
+There are other values of the flush parameter that are used in more advanced applications. You can
+force <tt>deflate()</tt> to produce a burst of output that encodes all of the input data provided
+so far, even if it wouldn't have otherwise, for example to control data latency on a link with
+compressed data. You can also ask that <tt>deflate()</tt> do that as well as erase any history up to
+that point so that what follows can be decompressed independently, for example for random access
+applications. Both requests will degrade compression by an amount depending on how often such
+requests are made.
+<p>
+<tt>deflate()</tt> has a return value that can indicate errors, yet we do not check it here. Why
+not? Well, it turns out that <tt>deflate()</tt> can do no wrong here. Let's go through
+<tt>deflate()</tt>'s return values and dispense with them one by one. The possible values are
+<tt>Z_OK</tt>, <tt>Z_STREAM_END</tt>, <tt>Z_STREAM_ERROR</tt>, or <tt>Z_BUF_ERROR</tt>. <tt>Z_OK</tt>
+is, well, ok. <tt>Z_STREAM_END</tt> is also ok and will be returned for the last call of
+<tt>deflate()</tt>. This is already guaranteed by calling <tt>deflate()</tt> with <tt>Z_FINISH</tt>
+until it has no more output. <tt>Z_STREAM_ERROR</tt> is only possible if the stream is not
+initialized properly, but we did initialize it properly. There is no harm in checking for
+<tt>Z_STREAM_ERROR</tt> here, for example to check for the possibility that some
+other part of the application inadvertently clobbered the memory containing the <em>zlib</em> state.
+<tt>Z_BUF_ERROR</tt> will be explained further below, but
+suffice it to say that this is simply an indication that <tt>deflate()</tt> could not consume
+more input or produce more output. <tt>deflate()</tt> can be called again with more output space
+or more available input, which it will be in this code.
+<pre><b>
+ ret = deflate(&amp;strm, flush); /* no bad return value */
+ assert(ret != Z_STREAM_ERROR); /* state not clobbered */
+</b></pre>
+Now we compute how much output <tt>deflate()</tt> provided on the last call, which is the
+difference between how much space was provided before the call, and how much output space
+is still available after the call. Then that data, if any, is written to the output file.
+We can then reuse the output buffer for the next call of <tt>deflate()</tt>. Again if there
+is a file i/o error, we call <tt>deflateEnd()</tt> before returning to avoid a memory leak.
+<pre><b>
+ have = CHUNK - strm.avail_out;
+ if (fwrite(out, 1, have, dest) != have || ferror(dest)) {
+ (void)deflateEnd(&amp;strm);
+ return Z_ERRNO;
+ }
+</b></pre>
+The inner <tt>do</tt>-loop is repeated until the last <tt>deflate()</tt> call fails to fill the
+provided output buffer. Then we know that <tt>deflate()</tt> has done as much as it can with
+the provided input, and that all of that input has been consumed. We can then fall out of this
+loop and reuse the input buffer.
+<p>
+The way we tell that <tt>deflate()</tt> has no more output is by seeing that it did not fill
+the output buffer, leaving <tt>avail_out</tt> greater than zero. However suppose that
+<tt>deflate()</tt> has no more output, but just so happened to exactly fill the output buffer!
+<tt>avail_out</tt> is zero, and we can't tell that <tt>deflate()</tt> has done all it can.
+As far as we know, <tt>deflate()</tt>
+has more output for us. So we call it again. But now <tt>deflate()</tt> produces no output
+at all, and <tt>avail_out</tt> remains unchanged as <tt>CHUNK</tt>. That <tt>deflate()</tt> call
+wasn't able to do anything, either consume input or produce output, and so it returns
+<tt>Z_BUF_ERROR</tt>. (See, I told you I'd cover this later.) However this is not a problem at
+all. Now we finally have the desired indication that <tt>deflate()</tt> is really done,
+and so we drop out of the inner loop to provide more input to <tt>deflate()</tt>.
+<p>
+With <tt>flush</tt> set to <tt>Z_FINISH</tt>, this final set of <tt>deflate()</tt> calls will
+complete the output stream. Once that is done, subsequent calls of <tt>deflate()</tt> would return
+<tt>Z_STREAM_ERROR</tt> if the flush parameter is not <tt>Z_FINISH</tt>, and do no more processing
+until the state is reinitialized.
+<p>
+Some applications of <em>zlib</em> have two loops that call <tt>deflate()</tt>
+instead of the single inner loop we have here. The first loop would call
+without flushing and feed all of the data to <tt>deflate()</tt>. The second loop would call
+<tt>deflate()</tt> with no more
+data and the <tt>Z_FINISH</tt> parameter to complete the process. As you can see from this
+example, that can be avoided by simply keeping track of the current flush state.
+<pre><b>
+ } while (strm.avail_out == 0);
+ assert(strm.avail_in == 0); /* all input will be used */
+</b></pre><!-- -->
+Now we check to see if we have already processed all of the input file. That information was
+saved in the <tt>flush</tt> variable, so we see if that was set to <tt>Z_FINISH</tt>. If so,
+then we're done and we fall out of the outer loop. We're guaranteed to get <tt>Z_STREAM_END</tt>
+from the last <tt>deflate()</tt> call, since we ran it until the last chunk of input was
+consumed and all of the output was generated.
+<pre><b>
+ /* done when last data in file processed */
+ } while (flush != Z_FINISH);
+ assert(ret == Z_STREAM_END); /* stream will be complete */
+</b></pre><!-- -->
+The process is complete, but we still need to deallocate the state to avoid a memory leak
+(or rather more like a memory hemorrhage if you didn't do this). Then
+finally we can return with a happy return value.
+<pre><b>
+ /* clean up and return */
+ (void)deflateEnd(&amp;strm);
+ return Z_OK;
+}
+</b></pre><!-- -->
+Now we do the same thing for decompression in the <tt>inf()</tt> routine. <tt>inf()</tt>
+decompresses what is hopefully a valid <em>zlib</em> stream from the input file and writes the
+uncompressed data to the output file. Much of the discussion above for <tt>def()</tt>
+applies to <tt>inf()</tt> as well, so the discussion here will focus on the differences between
+the two.
+<pre><b>
+/* Decompress from file source to file dest until stream ends or EOF.
+ inf() returns Z_OK on success, Z_MEM_ERROR if memory could not be
+ allocated for processing, Z_DATA_ERROR if the deflate data is
+ invalid or incomplete, Z_VERSION_ERROR if the version of zlib.h and
+ the version of the library linked do not match, or Z_ERRNO if there
+ is an error reading or writing the files. */
+int inf(FILE *source, FILE *dest)
+{
+</b></pre>
+The local variables have the same functionality as they do for <tt>def()</tt>. The
+only difference is that there is no <tt>flush</tt> variable, since <tt>inflate()</tt>
+can tell from the <em>zlib</em> stream itself when the stream is complete.
+<pre><b>
+ int ret;
+ unsigned have;
+ z_stream strm;
+ char in[CHUNK];
+ char out[CHUNK];
+</b></pre><!-- -->
+The initialization of the state is the same, except that there is no compression level,
+of course, and two more elements of the structure are initialized. <tt>avail_in</tt>
+and <tt>next_in</tt> must be initialized before calling <tt>inflateInit()</tt>. This
+is because the application has the option to provide the start of the zlib stream in
+order for <tt>inflateInit()</tt> to have access to information about the compression
+method to aid in memory allocation. In the current implementation of <em>zlib</em>
+(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of
+<tt>inflate()</tt> anyway. However those fields must be initialized since later versions
+of <em>zlib</em> that provide more compression methods may take advantage of this interface.
+In any case, no decompression is performed by <tt>inflateInit()</tt>, so the
+<tt>avail_out</tt> and <tt>next_out</tt> fields do not need to be initialized before calling.
+<p>
+Here <tt>avail_in</tt> is set to zero and <tt>next_in</tt> is set to <tt>Z_NULL</tt> to
+indicate that no input data is being provided.
+<pre><b>
+ /* allocate inflate state */
+ strm.zalloc = Z_NULL;
+ strm.zfree = Z_NULL;
+ strm.opaque = Z_NULL;
+ strm.avail_in = 0;
+ strm.next_in = Z_NULL;
+ ret = inflateInit(&amp;strm);
+ if (ret != Z_OK)
+ return ret;
+</b></pre><!-- -->
+The outer <tt>do</tt>-loop decompresses input until <tt>inflate()</tt> indicates
+that it has reached the end of the compressed data and has produced all of the uncompressed
+output. This is in contrast to <tt>def()</tt> which processes all of the input file.
+If end-of-file is reached before the compressed data self-terminates, then the compressed
+data is incomplete and an error is returned.
+<pre><b>
+ /* decompress until deflate stream ends or end of file */
+ do {
+</b></pre>
+We read input data and set the <tt>strm</tt> structure accordingly. If we've reached the
+end of the input file, then we leave the outer loop and report an error, since the
+compressed data is incomplete. Note that we may read more data than is eventually consumed
+by <tt>inflate()</tt>, if the input file continues past the <em>zlib</em> stream.
+For applications where <em>zlib</em> streams are embedded in other data, this routine would
+need to be modified to return the unused data, or at least indicate how much of the input
+data was not used, so the application would know where to pick up after the <em>zlib</em> stream.
+<pre><b>
+ strm.avail_in = fread(in, 1, CHUNK, source);
+ if (ferror(source)) {
+ (void)inflateEnd(&amp;strm);
+ return Z_ERRNO;
+ }
+ if (strm.avail_in == 0)
+ break;
+ strm.next_in = in;
+</b></pre><!-- -->
+The inner <tt>do</tt>-loop has the same function it did in <tt>def()</tt>, which is to
+keep calling <tt>inflate()</tt> until has generated all of the output it can with the
+provided input.
+<pre><b>
+ /* run inflate() on input until output buffer not full */
+ do {
+</b></pre>
+Just like in <tt>def()</tt>, the same output space is provided for each call of <tt>inflate()</tt>.
+<pre><b>
+ strm.avail_out = CHUNK;
+ strm.next_out = out;
+</b></pre>
+Now we run the decompression engine itself. There is no need to adjust the flush parameter, since
+the <em>zlib</em> format is self-terminating. The main difference here is that there are
+return values that we need to pay attention to. <tt>Z_DATA_ERROR</tt>
+indicates that <tt>inflate()</tt> detected an error in the <em>zlib</em> compressed data format,
+which means that either the data is not a <em>zlib</em> stream to begin with, or that the data was
+corrupted somewhere along the way since it was compressed. The other error to be processed is
+<tt>Z_MEM_ERROR</tt>, which can occur since memory allocation is deferred until <tt>inflate()</tt>
+needs it, unlike <tt>deflate()</tt>, whose memory is allocated at the start by <tt>deflateInit()</tt>.
+<p>
+Advanced applications may use
+<tt>deflateSetDictionary()</tt> to prime <tt>deflate()</tt> with a set of likely data to improve the
+first 32K or so of compression. This is noted in the <em>zlib</em> header, so <tt>inflate()</tt>
+requests that that dictionary be provided before it can start to decompress. Without the dictionary,
+correct decompression is not possible. For this routine, we have no idea what the dictionary is,
+so the <tt>Z_NEED_DICT</tt> indication is converted to a <tt>Z_DATA_ERROR</tt>.
+<p>
+<tt>inflate()</tt> can also return <tt>Z_STREAM_ERROR</tt>, which should not be possible here,
+but could be checked for as noted above for <tt>def()</tt>. <tt>Z_BUF_ERROR</tt> does not need to be
+checked for here, for the same reasons noted for <tt>def()</tt>. <tt>Z_STREAM_END</tt> will be
+checked for later.
+<pre><b>

+The output of <tt>inflate()</tt> is handled identically to that of <tt>deflate()</tt>.

+The inner <tt>do</tt>-loop ends when <tt>inflate()</tt> has no more output as indicated

+assert that <tt>strm.avail_in</tt> will be zero, since the deflate stream may end before the file
+does.
+<pre><b>
+ } while (strm.avail_out == 0);
+</b></pre><!-- -->
+The outer <tt>do</tt>-loop ends when <tt>inflate()</tt> reports that it has reached the
+end of the input <em>zlib</em> stream, has completed the decompression and integrity
+check, and has provided all of the output. This is indicated by the <tt>inflate()</tt>
+return value <tt>Z_STREAM_END</tt>. The inner loop is guaranteed to leave <tt>ret</tt>
+equal to <tt>Z_STREAM_END</tt> if the last chunk of the input file read contained the end
+of the <em>zlib</em> stream. So if the return value is not <tt>Z_STREAM_END</tt>, the
+loop continues to read more input.
+<pre><b>
+ /* done when inflate() says it's done */
+ } while (ret != Z_STREAM_END);
+</b></pre><!-- -->
+At this point, decompression successfully completed, or we broke out of the loop due to no
+more data being available from the input file. If the last <tt>inflate()</tt> return value
+is not <tt>Z_STREAM_END</tt>, then the <em>zlib</em> stream was incomplete and a data error
+is returned. Otherwise, we return with a happy return value. Of course, <tt>inflateEnd()</tt>
+is called first to avoid a memory leak.

+ /* clean up and return */
+ (void)inflateEnd(&amp;strm);

+That ends the routines that directly use <em>zlib</em>. The following routines make this
+a command-line program by running data through the above routines from <tt>stdin</tt> to
+<tt>stdout</tt>, and handling any errors reported by <tt>def()</tt> or <tt>inf()</tt>.
+<p>
+<tt>zerr()</tt> is used to interpret the possible error codes from <tt>def()</tt>

+ Version 1.0 29 May 2005 Mark Adler */
+
+/* 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 referece for locating a desired starting
+ point in the uncompressed stream. build_index() 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 accees 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 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.

+See below some functions declarations for Visual Basic.
+
+Frequently Asked Question:
+
+Q: Each time I use the compress function I get the -5 error (not enough
+ room in the output buffer).
+
+A: Make sure that the length of the compressed buffer is passed by
+ reference ("as any"), not by value ("as long"). Also check that
+ before the call of compress this length is equal to the total size of
+ the compressed buffer and not zero.

+<a name="Introduction"><h2> Introduction </h2>
+ The 'zlib' compression library provides in-memory compression and
+ decompression functions, including integrity checks of the uncompressed
+ data. This version of the library supports only one compression method
+ (deflation) but other algorithms will be added later and will have the same
+ stream interface.
+ <p>
+
+ Compression can be done in a single step if the buffers are large
+ enough (for example if an input file is mmap'ed), or can be done by
+ repeated calls of the compression function. In the latter case, the
+ application must provide more input and/or consume the output
+ (providing more output space) before each call.
+ <p>
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio.
+ <p>
+
+ The library does not install any signal handler. The decoder checks
+ the consistency of the compressed data, so the library should never
+ crash even in case of corrupted input.
+ <p>
+
+<hr>
+<a name="Utility functions"><h2> Utility functions </h2>
+ The following utility functions are implemented on top of the
+ <a href="#Basic functions">basic stream-oriented functions</a>.
+ To simplify the interface, some
+ default options are assumed (compression level and memory usage,
+ standard memory allocation functions). The source code of these
+ utility functions can easily be modified if you need special options.

+
+ The detailed semantics are as follows. <a href="#deflate">deflate</a> performs one or both of the
+ following actions:
+
+ <ul>
+ <li> Compress more input starting at <a href="#next_in">next_in</a> and update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a>

+ <li>
+ Provide more output starting at <a href="#next_out">next_out</a> and update <a href="#next_out">next_out</a> and <a href="#avail_out">avail_out</a>
+ accordingly. This action is forced if the parameter flush is non zero.
+ Forcing flush frequently degrades the compression ratio, so this parameter
+ should be set only when necessary (in interactive applications).
+ Some output may be provided even if flush is not set.
+ </ul> <p>
+
+ Before the call of <a href="#deflate">deflate</a>(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming
+ more output, and updating <a href="#avail_in">avail_in</a> or <a href="#avail_out">avail_out</a> accordingly ; <a href="#avail_out">avail_out</a>
+ should never be zero before the call. The application can consume the
+ compressed output when it wants, for example when the output buffer is full
+ (<a href="#avail_out">avail_out</a> == 0), or after each call of <a href="#deflate">deflate</a>(). If <a href="#deflate">deflate</a> returns <a href="#Z_OK">Z_OK</a>
+ and with zero <a href="#avail_out">avail_out</a>, it must be called again after making room in the
+ output buffer because there might be more output pending.
+ <p>
+
+ If the parameter flush is set to <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, all pending output is
+ flushed to the output buffer and the output is aligned on a byte boundary, so
+ that the decompressor can get all input data available so far. (In particular
+ <a href="#avail_in">avail_in</a> is zero after the call if enough output space has been provided
+ before the call.) Flushing may degrade compression for some compression
+ algorithms and so it should be used only when necessary.
+ <p>
+
+ If flush is set to <a href="#Z_FULL_FLUSH">Z_FULL_FLUSH</a>, all output is flushed as with
+ <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, and the compression <a href="#state">state</a> is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using <a href="#Z_FULL_FLUSH">Z_FULL_FLUSH</a> too often can seriously degrade
+ the compression.
+ <p>
+
+ If <a href="#deflate">deflate</a> returns with <a href="#avail_out">avail_out</a> == 0, this function must be called again
+ with the same value of the flush parameter and more output space (updated
+ <a href="#avail_out">avail_out</a>), until the flush is complete (<a href="#deflate">deflate</a> returns with non-zero
+ <a href="#avail_out">avail_out</a>).
+ <p>

+
+ <a href="#Z_FINISH">Z_FINISH</a> can be used immediately after <a href="#deflateInit">deflateInit</a> if all the compression

+ Initializes the compression dictionary from the given byte sequence

+
+ The dictionary should consist of strings (byte sequences) that are likely

+This directory contains project files for building zlib under various
+Integrated Development Environments (IDE).
+
+If you wish to submit a new project to this directory, you should comply
+to the following requirements. Otherwise (e.g. if you wish to integrate
+a custom piece of code that changes the zlib interface or its behavior),
+please consider submitting the project to the contrib directory.
+
+
+Requirements
+============
+
+- The project must build zlib using the source files from the official
+ zlib source distribution, exclusively.
+
+- If the project produces redistributable builds (e.g. shared objects
+ or DLL files), these builds must be compatible to those produced by
+ makefiles, if such makefiles exist in the zlib distribution.
+ In particular, if the project produces a DLL build for the Win32
+ platform, this build must comply to the officially-ammended Win32 DLL
+ Application Binary Interface (ABI), described in win32/DLL_FAQ.txt.
+
+- The project may provide additional build targets, which depend on
+ 3rd-party (unofficially-supported) software, present in the contrib
+ directory. For example, it is possible to provide an "ASM build",
+ besides the officially-supported build, and have ASM source files
+ among its dependencies.
+
+- If there are significant differences between the project files created
+ by different versions of an IDE (e.g. Visual C++ 6.0 vs. 7.0), the name
+ of the project directory should contain the version number of the IDE
+ for which the project is intended (e.g. "visualc6" for Visual C++ 6.0,
+ or "visualc7" for Visual C++ 7.0 and 7.1).
