-// The data format used by the zlib library is described by RFCs (Request for
-// Comments) 1950 to 1952 in the files ftp://ds.internic.net/rfc/rfc1950.txt
-// (zlib format), rfc1951.txt (deflate format) and rfc1952.txt (gzip format).
-//
-//
-// 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.
-//
-// 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.
-//
-// The library also supports reading and writing files in gzip (.gz) format
-// with an interface similar to that of stdio.
-//
-// 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.

-int inflate (z_streamp strm, int flush);
-//
-// inflate decompresses as much data as possible, and stops when the input
-// buffer becomes empty or the output buffer becomes full. It may some
-// introduce some output latency (reading input without producing any output)
-// except when forced to flush.
-//
-// The detailed semantics are as follows. inflate performs one or both of the
-// following actions:
-//
-// - Decompress more input starting at next_in and update next_in and avail_in
-// accordingly. If not all input can be processed (because there is not
-// enough room in the output buffer), next_in is updated and processing
-// will resume at this point for the next call of inflate().
-//
-// - Provide more output starting at next_out and update next_out and avail_out
-// accordingly. inflate() provides as much output as possible, until there
-// is no more input data or no more space in the output buffer (see below
-// about the flush parameter).
-//
-// Before the call of inflate(), the application should ensure that at least
-// one of the actions is possible, by providing more input and/or consuming
-// more output, and updating the next_* and avail_* values accordingly.
-// The application can consume the uncompressed output when it wants, for
-// example when the output buffer is full (avail_out == 0), or after each
-// call of inflate(). If inflate returns Z_OK and with zero avail_out, it
-// must be called again after making room in the output buffer because there
-// might be more output pending.
-//
-// If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
-// output as possible to the output buffer. The flushing behavior of inflate is
-// not specified for values of the flush parameter other than Z_SYNC_FLUSH
-// and Z_FINISH, but the current implementation actually flushes as much output
-// as possible anyway.
-//
-// inflate() should normally be called until it returns Z_STREAM_END or an
-// error. However if all decompression is to be performed in a single step
-// (a single call of inflate), the parameter flush should be set to
-// Z_FINISH. In this case all pending input is processed and all pending
-// output is flushed; avail_out must be large enough to hold all the
-// uncompressed data. (The size of the uncompressed data may have been saved
-// by the compressor for this purpose.) The next operation on this stream must
-// be inflateEnd to deallocate the decompression state. The use of Z_FINISH
-// is never required, but can be used to inform inflate that a faster routine
-// may be used for the single inflate() call.
-//
-// If a preset dictionary is needed at this point (see inflateSetDictionary
-// below), inflate sets strm-adler to the adler32 checksum of the
-// dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise
-// it sets strm->adler to the adler32 checksum of all output produced
-// so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
-// an error code as described below. At the end of the stream, inflate()
-// checks that its computed adler32 checksum is equal to that saved by the
-// compressor and returns Z_STREAM_END only if the checksum is correct.
-//
-// inflate() returns Z_OK if some progress has been made (more input processed
-// or more output produced), Z_STREAM_END if the end of the compressed data has
-// been reached and all uncompressed output has been produced, Z_NEED_DICT if a
-// preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
-// corrupted (input stream not conforming to the zlib format or incorrect
-// adler32 checksum), Z_STREAM_ERROR if the stream structure was inconsistent
-// (for example if next_in or next_out was NULL), Z_MEM_ERROR if there was not
-// enough memory, Z_BUF_ERROR if no progress is possible or if there was not
-// enough room in the output buffer when Z_FINISH is used. In the Z_DATA_ERROR
-// case, the application may then call inflateSync to look for a good
-// compression block.
-//
-
-
-int inflateEnd (z_streamp strm);
-//
-// All dynamically allocated data structures for this stream are freed.
-// This function discards any unprocessed input and does not flush any
-// pending output.
-//
-// inflateEnd returns Z_OK if success, Z_STREAM_ERROR if the stream state
-// was inconsistent. In the error case, msg may be set but then points to a
-// static string (which must not be deallocated).
-
- // Advanced functions
-
-// The following functions are needed only in some special applications.
-
-
-
-
-
-int inflateSetDictionary (z_streamp strm,
- const Byte *dictionary,
- uInt dictLength);
-//
-// Initializes the decompression dictionary from the given uncompressed byte
-// sequence. This function must be called immediately after a call of inflate
-// if this call returned Z_NEED_DICT. The dictionary chosen by the compressor
-// can be determined from the Adler32 value returned by this call of
-// inflate. The compressor and decompressor must use exactly the same
-// dictionary.
-//
-// inflateSetDictionary returns Z_OK if success, Z_STREAM_ERROR if a
-// parameter is invalid (such as NULL dictionary) or the stream state is
-// inconsistent, Z_DATA_ERROR if the given dictionary doesn't match the
-// expected one (incorrect Adler32 value). inflateSetDictionary does not
-// perform any decompression: this will be done by subsequent calls of
-// inflate().
-
-
-int inflateSync (z_streamp strm);
-//
-// Skips invalid compressed data until a full flush point can be found, or until all
-// available input is skipped. No output is provided.
-//
-// inflateSync returns Z_OK if a full flush point has been found, Z_BUF_ERROR
-// if no more input was provided, Z_DATA_ERROR if no flush point has been found,
-// or Z_STREAM_ERROR if the stream structure was inconsistent. In the success
-// case, the application may save the current current value of total_in which
-// indicates where valid compressed data was found. In the error case, the
-// application may repeatedly call inflateSync, providing more input each time,
-// until success or end of the input data.
-
-
-int inflateReset (z_streamp strm);
-// This function is equivalent to inflateEnd followed by inflateInit,
-// but does not free and reallocate all the internal decompression state.
-// The stream will keep attributes that may have been set by inflateInit2.

-// Notes beyond the 1.93a appnote.txt:
-//
-// 1. Distance pointers never point before the beginning of the output stream.
-// 2. Distance pointers can point back across blocks, up to 32k away.
-// 3. There is an implied maximum of 7 bits for the bit length table and
-// 15 bits for the actual data.
-// 4. If only one code exists, then it is encoded using one bit. (Zero
-// would be more efficient, but perhaps a little confusing.) If two
-// codes exist, they are coded using one bit each (0 and 1).
-// 5. There is no way of sending zero distance codes--a dummy must be
-// sent if there are none. (History: a pre 2.0 version of PKZIP would
-// store blocks with no distance codes, but this was discovered to be
-// too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
-// zero distance codes, which is sent as one code of zero bits in
-// length.
-// 6. There are up to 286 literal/length codes. Code 256 represents the
-// end-of-block. Note however that the static length tree defines
-// 288 codes just to fill out the Huffman codes. Codes 286 and 287
-// cannot be used though, since there is no length base or extra bits
-// defined for them. Similarily, there are up to 30 distance codes.
-// However, static trees define 32 codes (all 5 bits) to fill out the
-// Huffman codes, but the last two had better not show up in the data.
-// 7. Unzip can check dynamic Huffman blocks for complete code sets.
-// The exception is that a single code would not be complete (see #4).
-// 8. The five bits following the block type is really the number of
-// literal codes sent minus 257.
-// 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-// (1+6+6). Therefore, to output three times the length, you output
-// three codes (1+1+1), whereas to output four times the same length,
-// you only need two codes (1+3). Hmm.
-//10. In the tree reconstruction algorithm, Code = Code + Increment
-// only if BitLength(i) is not zero. (Pretty obvious.)
-//11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
-//12. Note: length code 284 can represent 227-258, but length code 285
-// really is 258. The last length deserves its own, short code
-// since it gets used a lot in very redundant files. The length
-// 258 is special since 258 - 3 (the min match length) is 255.
-//13. The literal/length and distance code bit lengths are read as a
-// single stream of lengths. It is possible (and advantageous) for
-// a repeat code (16, 17, or 18) to go across the boundary between
-// the two sets of lengths.

-// Huffman code decoding is performed using a multi-level table lookup.
-// The fastest way to decode is to simply build a lookup table whose
-// size is determined by the longest code. However, the time it takes
-// to build this table can also be a factor if the data being decoded
-// is not very long. The most common codes are necessarily the
-// shortest codes, so those codes dominate the decoding time, and hence
-// the speed. The idea is you can have a shorter table that decodes the
-// shorter, more probable codes, and then point to subsidiary tables for
-// the longer codes. The time it costs to decode the longer codes is
-// then traded against the time it takes to make longer tables.
-//
-// This results of this trade are in the variables lbits and dbits
-// below. lbits is the number of bits the first level table for literal/
-// length codes can decode in one step, and dbits is the same thing for
-// the distance codes. Subsequent tables are also less than or equal to
-// those sizes. These values may be adjusted either when all of the
-// codes are shorter than that, in which case the longest code length in
-// bits is used, or when the shortest code is *longer* than the requested
-// table size, in which case the length of the shortest code in bits is
-// used.
-//
-// There are two different values for the two tables, since they code a
-// different number of possibilities each. The literal/length table
-// codes 286 possible values, or in a flat code, a little over eight
-// bits. The distance table codes 30 possible values, or a little less
-// than five bits, flat. The optimum values for speed end up being
-// about one bit more than those, so lbits is 8+1 and dbits is 5+1.
-// The optimum values may differ though from machine to machine, and
-// possibly even between compilers. Your mileage may vary.

-#define LIT_BUFSIZE 0x8000
-#define DIST_BUFSIZE LIT_BUFSIZE
-// Sizes of match buffers for literals/lengths and distances. There are
-// 4 reasons for limiting LIT_BUFSIZE to 64K:
-// - frequencies can be kept in 16 bit counters
-// - if compression is not successful for the first block, all input data is
-// still in the window so we can still emit a stored block even when input
-// comes from standard input. (This can also be done for all blocks if
-// LIT_BUFSIZE is not greater than 32K.)
-// - if compression is not successful for a file smaller than 64K, we can
-// even emit a stored file instead of a stored block (saving 5 bytes).
-// - creating new Huffman trees less frequently may not provide fast
-// adaptation to changes in the input data statistics. (Take for
-// example a binary file with poorly compressible code followed by
-// a highly compressible string table.) Smaller buffer sizes give
-// fast adaptation but have of course the overhead of transmitting trees
-// more frequently.
-// - I can't count above 4
-// The current code is general and allows DIST_BUFSIZE < LIT_BUFSIZE (to save
-// memory at the expense of compression). Some optimizations would be possible
-// if we rely on DIST_BUFSIZE == LIT_BUFSIZE.

-// CreateZip()
-//
-// Purpose: Create a zip archive file
-//
-// Parameters: z - archive file name if flags is ZIP_FILENAME; for other
-// uses see below
-// len - for memory (ZIP_MEMORY) should be the buffer size;
-// for other uses, should be 0
-// flags - indicates usage, see below; for files, this will be
-// ZIP_FILENAME
-//
-// Returns: HZIP - non-zero if zip archive created ok, otherwise 0
-//
-HZIP CreateZip(void *z, unsigned int len, DWORD flags);
-// CreateZip - call this to start the creation of a zip file.
-// As the zip is being created, it will be stored somewhere:
-// to a pipe: CreateZip(hpipe_write, 0,ZIP_HANDLE);
-// in a file (by handle): CreateZip(hfile, 0,ZIP_HANDLE);
-// in a file (by name): CreateZip("c:\\test.zip", 0,ZIP_FILENAME);
-// in memory: CreateZip(buf, len,ZIP_MEMORY);
-// or in pagefile memory: CreateZip(0, len,ZIP_MEMORY);
-// The final case stores it in memory backed by the system paging file,
-// where the zip may not exceed len bytes. This is a bit friendlier than
-// allocating memory with new[]: it won't lead to fragmentation, and the
-// memory won't be touched unless needed.
-// Note: because pipes don't allow random access, the structure of a zipfile
-// created into a pipe is slightly different from that created into a file
-// or memory. In particular, the compressed-size of the item cannot be
-// stored in the zipfile until after the item itself. (Also, for an item added
-// itself via a pipe, the uncompressed-size might not either be known until
-// after.) This is not normally a problem. But if you try to unzip via a pipe
-// as well, then the unzipper will not know these things about the item until
-// after it has been unzipped. Therefore: for unzippers which don't just write
-// each item to disk or to a pipe, but instead pre-allocate memory space into
-// which to unzip them, then either you have to create the zip not to a pipe,
-// or you have to add items not from a pipe, or at least when adding items
-// from a pipe you have to specify the length.

-//
-// ZipAdd()
-//
-// Purpose: Add a file to a zip archive
-//
-// Parameters: hz - handle to an open zip archive
-// dstzn - name used inside the zip archive to identify the file
-// src - for a file (ZIP_FILENAME) this specifies the filename
-// to be added to the archive; for other uses, see below
-// len - for memory (ZIP_MEMORY) this specifies the buffer
-// length; for other uses, this should be 0
-// flags - indicates usage, see below; for files, this will be
-// ZIP_FILENAME
-//
-// Returns: ZRESULT - ZR_OK if success, otherwise some other value
-//
-ZRESULT ZipAdd(HZIP hz, const TCHAR *dstzn, void *src, unsigned int len, DWORD flags);
-// ZipAdd - call this for each file to be added to the zip.
-// dstzn is the name that the file will be stored as in the zip file.
-// The file to be added to the zip can come
-// from a pipe: ZipAdd(hz,"file.dat", hpipe_read,0,ZIP_HANDLE);
-// from a file: ZipAdd(hz,"file.dat", hfile,0,ZIP_HANDLE);
-// from a fname: ZipAdd(hz,"file.dat", "c:\\docs\\origfile.dat",0,ZIP_FILENAME);
-// from memory: ZipAdd(hz,"subdir\\file.dat", buf,len,ZIP_MEMORY);
-// (folder): ZipAdd(hz,"subdir", 0,0,ZIP_FOLDER);
-// Note: if adding an item from a pipe, and if also creating the zip file itself
-// to a pipe, then you might wish to pass a non-zero length to the ZipAdd
-// function. This will let the zipfile store the items size ahead of the
-// compressed item itself, which in turn makes it easier when unzipping the
-// zipfile into a pipe.

-// CloseZip()
-//
-// Purpose: Close an open zip archive
-//
-// Parameters: hz - handle to an open zip archive
-//
-// Returns: ZRESULT - ZR_OK if success, otherwise some other value
-//
-ZRESULT CloseZip(HZIP hz);
-// CloseZip - the zip handle must be closed with this function.
-
-
-ZRESULT ZipGetMemory(HZIP hz, void **buf, unsigned long *len);
-// ZipGetMemory - If the zip was created in memory, via ZipCreate(0,ZIP_MEMORY),
-// then this function will return information about that memory block.
-// buf will receive a pointer to its start, and len its length.
-// Note: you can't add any more after calling this.
-
-
-unsigned int FormatZipMessage(ZRESULT code, char *buf,unsigned int len);
-// FormatZipMessage - given an error code, formats it as a string.
-// It returns the length of the error message. If buf/len points
-// to a real buffer, then it also writes as much as possible into there.
-
-
-
-// These are the result codes:
-#define ZR_OK 0x00000000 // nb. the pseudo-code zr-recent is never returned,
-#define ZR_RECENT 0x00000001 // but can be passed to FormatZipMessage.
-// The following come from general system stuff (e.g. files not openable)
-#define ZR_GENMASK 0x0000FF00
-#define ZR_NODUPH 0x00000100 // couldn't duplicate the handle
-#define ZR_NOFILE 0x00000200 // couldn't create/open the file
-#define ZR_NOALLOC 0x00000300 // failed to allocate some resource
-#define ZR_WRITE 0x00000400 // a general error writing to the file
-#define ZR_NOTFOUND 0x00000500 // couldn't find that file in the zip
-#define ZR_MORE 0x00000600 // there's still more data to be unzipped
-#define ZR_CORRUPT 0x00000700 // the zipfile is corrupt or not a zipfile
-#define ZR_READ 0x00000800 // a general error reading the file
-// The following come from mistakes on the part of the caller
-#define ZR_CALLERMASK 0x00FF0000
-#define ZR_ARGS 0x00010000 // general mistake with the arguments
-#define ZR_NOTMMAP 0x00020000 // tried to ZipGetMemory, but that only works on mmap zipfiles, which yours wasn't
-#define ZR_MEMSIZE 0x00030000 // the memory size is too small
-#define ZR_FAILED 0x00040000 // the thing was already failed when you called this function
-#define ZR_ENDED 0x00050000 // the zip creation has already been closed
-#define ZR_MISSIZE 0x00060000 // the indicated input file size turned out mistaken
-#define ZR_PARTIALUNZ 0x00070000 // the file had already been partially unzipped
-#define ZR_ZMODE 0x00080000 // tried to mix creating/opening a zip
-// The following come from bugs within the zip library itself
-#define ZR_BUGMASK 0xFF000000
-#define ZR_NOTINITED 0x01000000 // initialisation didn't work
-#define ZR_SEEK 0x02000000 // trying to seek in an unseekable file
-#define ZR_NOCHANGE 0x04000000 // changed its mind on storage, but not allowed
-#define ZR_FLATE 0x05000000 // an internal error in the de/inflation code
-
-
-
-// e.g.
-//
-// (1) Traditional use, creating a zipfile from existing files
-// HZIP hz = CreateZip("c:\\temp.zip",0,ZIP_FILENAME);
-// ZipAdd(hz,"src1.txt", "c:\\src1.txt",0,ZIP_FILENAME);
-// ZipAdd(hz,"src2.bmp", "c:\\src2_origfn.bmp",0,ZIP_FILENAME);
-// CloseZip(hz);
-//
-// (2) Memory use, creating an auto-allocated mem-based zip file from various sources
-// HZIP hz = CreateZip(0,100000,ZIP_MEMORY);
-// // adding a conventional file...
-// ZipAdd(hz,"src1.txt", "c:\\src1.txt",0,ZIP_FILENAME);
-// // adding something from memory...
-// char buf[1000]; for (int i=0; i<1000; i++) buf[i]=(char)(i&0x7F);
-// ZipAdd(hz,"file.dat", buf,1000,ZIP_MEMORY);
-// // adding something from a pipe...
-// HANDLE hread,hwrite; CreatePipe(&hread,&write,NULL,0);
-// HANDLE hthread = CreateThread(ThreadFunc,(void*)hwrite);
-// ZipAdd(hz,"unz3.dat", hread,0,ZIP_HANDLE);
-// WaitForSingleObject(hthread,INFINITE);
-// CloseHandle(hthread); CloseHandle(hread);
-// ... meanwhile DWORD CALLBACK ThreadFunc(void *dat)
-// { HANDLE hwrite = (HANDLE)dat;
-// char buf[1000]={17};
-// DWORD writ; WriteFile(hwrite,buf,1000,&writ,NULL);
-// CloseHandle(hwrite);
-// return 0;
-// }
-// // and now that the zip is created, let's do something with it:
-// void *zbuf; unsigned long zlen; ZipGetMemory(hz,&zbuf,&zlen);
-// HANDLE hfz = CreateFile("test2.zip",GENERIC_WRITE,CREATE_ALWAYS);
-// DWORD writ; WriteFile(hfz,zbuf,zlen,&writ,NULL);
-// CloseHandle(hfz);
-// CloseZip(hz);
-//
-// (3) Handle use, for file handles and pipes
-// HANDLE hzread,hzwrite; CreatePipe(&hzread,&hzwrite);
-// HANDLE hthread = CreateThread(ZipReceiverThread,(void*)hread);
-// HZIP hz = ZipCreate(hzwrite,ZIP_HANDLE);
-// // ... add to it
-// CloseZip(hz);
-// CloseHandle(hzwrite);
-// WaitForSingleObject(hthread,INFINITE);
-// CloseHandle(hthread);
-// ... meanwhile DWORD CALLBACK ThreadFunc(void *dat)
-// { HANDLE hread = (HANDLE)dat;
-// char buf[1000];
-// while (true)
-// { DWORD red; ReadFile(hread,buf,1000,&red,NULL);
-// // ... and do something with this zip data we're receiving
-// if (red==0) break;
-// }
-// CloseHandle(hread);
-// return 0;
-// }
-//
-
-
-// Now we indulge in a little skullduggery so that the code works whether
-// the user has included just zip or both zip and unzip.
-// Idea: if header files for both zip and unzip are present, then presumably
-// the cpp files for zip and unzip are both present, so we will call
-// one or the other of them based on a dynamic choice. If the header file
-// for only one is present, then we will bind to that particular one.

+ZLIB DATA COMPRESSION LIBRARY
+
+zlib 1.2.8 is a general purpose data compression library. All the code is
+thread safe. The data format used by the zlib library is described by RFCs
+(Request for Comments) 1950 to 1952 in the files
+http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
+rfc1952 (gzip format).
+
+All functions of the compression library are documented in the file zlib.h
+(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
+of the library is given in the file test/example.c which also tests that
+the library is working correctly. Another example is given in the file
+test/minigzip.c. The compression library itself is composed of all source
+files in the root directory.
+
+To compile all files and run the test program, follow the instructions given at
+the top of Makefile.in. In short "./configure; make test", and if that goes
+well, "make install" should work for most flavors of Unix. For Windows, use
+one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use
+make_vms.com.
+
+Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
+<info@winimage.com> for the Windows DLL version. The zlib home page is
+http://zlib.net/ . Before reporting a problem, please check this site to
+verify that you have the latest version of zlib; otherwise get the latest
+version and check whether the problem still exists or not.
+
+PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
+
+Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
+issue of Dr. Dobb's Journal; a copy of the article is available at
+http://marknelson.us/1997/01/01/zlib-engine/ .
+
+The changes made in version 1.2.8 are documented in the file ChangeLog.
+
+Unsupported third party contributions are provided in directory contrib/ .
+
+zlib is available in Java using the java.util.zip package, documented at
+http://java.sun.com/developer/technicalArticles/Programming/compression/ .
+
+A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
+at CPAN (Comprehensive Perl Archive Network) sites, including
+http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
+
+A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
+available in Python 1.5 and later versions, see
+http://docs.python.org/library/zlib.html .
+
+zlib is built into tcl: http://wiki.tcl.tk/4610 .
+
+An experimental package to read and write files in .zip format, written on top
+of zlib by Gilles Vollant <info@winimage.com>, is available in the
+contrib/minizip directory of zlib.
+
+
+Notes for some targets:
+
+- For Windows DLL versions, please see win32/DLL_FAQ.txt
+
+- For 64-bit Irix, deflate.c must be compiled without any optimization. With
+ -O, one libpng test fails. The test works in 32 bit mode (with the -n32
+ compiler flag). The compiler bug has been reported to SGI.
+
+- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
+ when compiled with cc.
+
+- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
+ necessary to get gzprintf working correctly. This is done by configure.
+
+- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
+ other compilers. Use "make test" to check your compiler.
+
+- gzdopen is not supported on RISCOS or BEOS.
+
+- For PalmOs, see http://palmzlib.sourceforge.net/
+
+
+Acknowledgments:
+
+ The deflate format used by zlib was defined by Phil Katz. The deflate and
+ zlib specifications were written by L. Peter Deutsch. Thanks to all the
+ people who reported problems and suggested various improvements in zlib; they
+ are too numerous to cite here.

+ Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:

+
+ Polynomials over GF(2) are represented in binary, one bit per coefficient,
+ with the lowest powers in the most significant bit. Then adding polynomials
+ is just exclusive-or, and multiplying a polynomial by x is a right shift by
+ one. If we call the above polynomial p, and represent a byte as the
+ polynomial q, also with the lowest power in the most significant bit (so the
+ byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+ where a mod b means the remainder after dividing a by b.
+
+ This calculation is done using the shift-register method of multiplying and
+ taking the remainder. The register is initialized to zero, and for each
+ incoming bit, x^32 is added mod p to the register if the bit is a one (where
+ x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+ x (which is shifting right by one and adding x^32 mod p if the bit shifted
+ out is a one). We start with the highest power (least significant bit) of
+ q and repeat for all eight bits of q.
+
+ The first table is simply the CRC of all possible eight bit values. This is
+ all the information needed to generate CRCs on data a byte at a time for all
+ combinations of CRC register values and incoming bytes. The remaining tables
+ allow for word-at-a-time CRC calculation for both big-endian and little-
+ endian machines, where a word is four bytes.

+/*
+ * ALGORITHM
+ *
+ * The "deflation" process depends on being able to identify portions
+ * of the input text which are identical to earlier input (within a
+ * sliding window trailing behind the input currently being processed).
+ *
+ * The most straightforward technique turns out to be the fastest for
+ * most input files: try all possible matches and select the longest.
+ * The key feature of this algorithm is that insertions into the string
+ * dictionary are very simple and thus fast, and deletions are avoided
+ * completely. Insertions are performed at each input character, whereas
+ * string matches are performed only when the previous match ends. So it
+ * is preferable to spend more time in matches to allow very fast string
+ * insertions and avoid deletions. The matching algorithm for small
+ * strings is inspired from that of Rabin & Karp. A brute force approach
+ * is used to find longer strings when a small match has been found.
+ * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
+ * (by Leonid Broukhis).
+ * A previous version of this file used a more sophisticated algorithm
+ * (by Fiala and Greene) which is guaranteed to run in linear amortized
+ * time, but has a larger average cost, uses more memory and is patented.
+ * However the F&G algorithm may be faster for some highly redundant
+ * files if the parameter max_chain_length (described below) is too large.
+ *
+ * ACKNOWLEDGEMENTS
+ *
+ * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
+ * I found it in 'freeze' written by Leonid Broukhis.
+ * Thanks to many people for bug reports and testing.
+ *
+ * REFERENCES
+ *
+ * Deutsch, L.P.,"DEFLATE Compressed Data Format Specification".
+ * Available in http://tools.ietf.org/html/rfc1951

+ filled the window with output, or when it completes with data in the

+
+ in() and out() are called with a descriptor parameter provided in 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

+ 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.

+/* inflate.c -- zlib decompression
+ * Copyright (C) 1995-2012 Mark Adler
+ * For conditions of distribution and use, see copyright notice in zlib.h
+ */
+
+/*
+ * Change history:
+ *
+ * 1.2.beta0 24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ * creation of window when not needed, minimize use of window when it is
+ * needed, make inffast.c even faster, implement gzip decoding, and to
+ * improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1 25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2 4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ * to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3 22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ * buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4 1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ * source file infback.c to provide a call-back interface to inflate for
+ * programs like gzip and unzip -- uses window as output buffer to avoid
+ * window copying
+ *
+ * 1.2.beta5 1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ * input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6 4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ * make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7 27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0 9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ * for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ * and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+ inflate() uses a state machine to process as much input data and generate as
+ much output data as possible before returning. The state machine is
+ structured roughly as follows:
+
+ for (;;) switch (state) {
+ ...
+ case STATEn:
+ if (not enough input data or output space to make progress)
+ return;
+ ... make progress ...
+ state = STATEm;
+ break;
+ ...
+ }
+
+ so when inflate() is called again, the same case is attempted again, and
+ if the appropriate resources are provided, the machine proceeds to the
+ next state. The NEEDBITS() macro is usually the way the state evaluates
+ whether it can proceed or should return. NEEDBITS() does the return if
+ the requested bits are not available. The typical use of the BITS macros
+ is:
+
+ NEEDBITS(n);
+ ... do something with BITS(n) ...
+ DROPBITS(n);
+
+ where NEEDBITS(n) either returns from inflate() if there isn't enough
+ input left to load n bits into the accumulator, or it continues. BITS(n)
+ gives the low n bits in the accumulator. When done, DROPBITS(n) drops
+ the low n bits off the accumulator. INITBITS() clears the accumulator
+ and sets the number of available bits to zero. BYTEBITS() discards just
+ enough bits to put the accumulator on a byte boundary. After BYTEBITS()
+ and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+ NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+ if there is no input available. The decoding of variable length codes uses
+ PULLBYTE() directly in order to pull just enough bytes to decode the next
+ code, and no more.
+
+ Some states loop until they get enough input, making sure that enough
+ state information is maintained to continue the loop where it left off
+ if NEEDBITS() returns in the loop. For example, want, need, and keep
+ would all have to actually be part of the saved state in case NEEDBITS()
+ returns:
+
+ case STATEw:
+ while (want < need) {
+ NEEDBITS(n);
+ keep[want++] = BITS(n);
+ DROPBITS(n);
+ }
+ state = STATEx;
+ case STATEx:
+
+ As shown above, if the next state is also the next case, then the break
+ is omitted.
+
+ A state may also return if there is not enough output space available to
+ complete that state. Those states are copying stored data, writing a
+ literal byte, and copying a matching string.
+
+ When returning, a "goto inf_leave" is used to update the total counters,
+ update the check value, and determine whether any progress has been made
+ during that inflate() call in order to return the proper return code.
+ Progress is defined as a change in either strm->avail_in or strm->avail_out.
+ When there is a window, goto inf_leave will update the window with the last
+ output written. If a goto inf_leave occurs in the middle of decompression
+ and there is no window currently, goto inf_leave will create one and copy
+ output to the window for the next call of inflate().
+
+ In this implementation, the flush parameter of inflate() only affects the
+ return code (per zlib.h). inflate() always writes as much as possible to
+ strm->next_out, given the space available and the provided input--the effect
+ documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers
+ the allocation of and copying into a sliding window until necessary, which
+ provides the effect documented in zlib.h for Z_FINISH when the entire input
+ stream available. So the only thing the flush parameter actually does is:
+ when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it
+ will return Z_BUF_ERROR if it has not reached the end of the stream.

+ 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.
+
+ Compression can be done in a single step if the buffers are large enough,
+ 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.
+
+ The compressed data format used by default by the in-memory functions is
+ the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
+ around a deflate stream, which is itself documented in RFC 1951.
+
+ The library also supports reading and writing files in gzip (.gz) format
+ with an interface similar to that of stdio using the functions that start
+ with "gz". The gzip format is different from the zlib format. gzip is a
+ gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
+
+ This library can optionally read and write gzip streams in memory as well.
+
+ The zlib format was designed to be compact and fast for use in memory

+ deflate compresses as much data as possible, and stops when the input
+ buffer becomes empty or the output buffer becomes full. It may introduce
+ some output latency (reading input without producing any output) except when
+ forced to flush.
+
+ The detailed semantics are as follows. deflate performs one or both of the
+ following actions:
+
+ - Compress more input starting at next_in and update next_in and avail_in
+ accordingly. If not all input can be processed (because there is not
+ enough room in the output buffer), next_in and avail_in are updated and
+ processing will resume at this point for the next call of deflate().
+
+ - Provide more output starting at next_out and update next_out and avail_out
+ 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.
+
+ Before the call of deflate(), the application should ensure that at least
+ one of the actions is possible, by providing more input and/or consuming more
+ output, and updating avail_in or avail_out accordingly; avail_out 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 (avail_out
+ == 0), or after each call of deflate(). If deflate returns Z_OK and with
+ zero avail_out, it must be called again after making room in the output
+ buffer because there might be more output pending.
+
+ Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+ decide how much data to accumulate before producing output, in order to
+ maximize compression.
+
+ If the parameter flush is set to Z_SYNC_FLUSH, 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 avail_in 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. This
+ completes the current deflate block and follows it with an empty stored block
+ that is three bits plus filler bits to the next byte, followed by four bytes
+ (00 00 ff ff).
+
+ If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+ output buffer, but the output is not aligned to a byte boundary. All of the
+ input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+ This completes the current deflate block and follows it with an empty fixed
+ codes block that is 10 bits long. This assures that enough bytes are output
+ in order for the decompressor to finish the block before the empty fixed code
+ block.
+
+ If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+ for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+ seven bits of the current block are held to be written as the next byte after
+ the next deflate block is completed. In this case, the decompressor may not
+ be provided enough bits at this point in order to complete decompression of
+ the data provided so far to the compressor. It may need to wait for the next
+ block to be emitted. This is for advanced applications that need to control
+ the emission of deflate blocks.
+
+ If flush is set to Z_FULL_FLUSH, all output is flushed as with
+ Z_SYNC_FLUSH, and the compression state is reset so that decompression can
+ restart from this point if previous compressed data has been damaged or if
+ random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
+ compression.
+
+ If deflate returns with avail_out == 0, this function must be called again
+ with the same value of the flush parameter and more output space (updated
+ avail_out), until the flush is complete (deflate returns with non-zero
+ avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
+ avail_out is greater than six to avoid repeated flush markers due to
+ avail_out == 0 on return.
+
+ If the parameter flush is set to Z_FINISH, pending input is processed,
+ pending output is flushed and deflate returns with Z_STREAM_END if there was
+ enough output space; if deflate returns with Z_OK, this function must be
+ called again with Z_FINISH and more output space (updated avail_out) but no
+ more input data, until it returns with Z_STREAM_END or an error. After
+ deflate has returned Z_STREAM_END, the only possible operations on the stream
+ are deflateReset or deflateEnd.
+
+ Z_FINISH can be used immediately after deflateInit if all the compression
+ is to be done in a single step. In this case, avail_out must be at least the
+ value returned by deflateBound (see below). Then deflate is guaranteed to
+ return Z_STREAM_END. If not enough output space is provided, deflate will
+ not return Z_STREAM_END, and it must be called again as described above.
+
+ deflate() sets strm->adler to the adler32 checksum of all input read
+ so far (that is, total_in bytes).
+
+ deflate() may update strm->data_type if it can make a good guess about
+ the input data type (Z_BINARY or Z_TEXT). In doubt, the data is considered
+ binary. This field is only for information purposes and does not affect the
+ compression algorithm in any manner.
+
+ deflate() returns Z_OK if some progress has been made (more input
+ processed or more output produced), Z_STREAM_END if all input has been
+ consumed and all output has been produced (only when flush is set to
+ Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
+ if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible

+
+ Before the call of inflate(), the application should ensure that at least

+ inflate(). If inflate returns Z_OK and with zero avail_out, it must be
+ called again after making room in the output buffer because there might be
+ more output pending.
+
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
+ Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate()
+ stop if and when it gets to the next deflate block boundary. When decoding
+ the zlib or gzip format, this will cause inflate() to return immediately
+ after the header and before the first block. When doing a raw inflate,
+ inflate() will go ahead and process the first block, and will return when it
+ gets to the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64 if
+ inflate() is currently decoding the last block in the deflate stream, plus
+ 128 if inflate() returned immediately after decoding an end-of-block code or
+ decoding the complete header up to just before the first byte of the deflate
+ stream. The end-of-block will not be indicated until all of the uncompressed
+ data from that block has been written to strm->next_out. The number of
+ unused bits may in general be greater than seven, except when bit 7 of
+ data_type is set, in which case the number of unused bits will be less than
+ eight. data_type is set as noted here every time inflate() returns for all
+ flush options, and so can be used to determine the amount of currently
+ consumed input in bits.
+
+ The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+ end of each deflate block header is reached, before any actual data in that
+ block is decoded. This allows the caller to determine the length of the
+ deflate block header for later use in random access within a deflate block.
+ 256 is added to the value of strm->data_type when inflate() returns
+ immediately after reaching the end of the deflate block header.
+
+ inflate() should normally be called until it returns Z_STREAM_END or an
+ error. However if all decompression is to be performed in a single step (a
+ single call of inflate), the parameter flush should be set to Z_FINISH. In
+ this case all pending input is processed and all pending output is flushed;
+ avail_out must be large enough to hold all of the uncompressed data for the
+ operation to complete. (The size of the uncompressed data may have been
+ saved by the compressor for this purpose.) The use of Z_FINISH is not
+ required to perform an inflation in one step. However it may be used to
+ inform inflate that a faster approach can be used for the single inflate()
+ call. Z_FINISH also informs inflate to not maintain a sliding window if the
+ stream completes, which reduces inflate's memory footprint. If the stream
+ does not complete, either because not all of the stream is provided or not
+ enough output space is provided, then a sliding window will be allocated and
+ inflate() can be called again to continue the operation as if Z_NO_FLUSH had
+ been used.
+
+ In this implementation, inflate() always flushes as much output as
+ possible to the output buffer, and always uses the faster approach on the
+ first call. So the effects of the flush parameter in this implementation are
+ on the return value of inflate() as noted below, when inflate() returns early
+ when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of
+ memory for a sliding window when Z_FINISH is used.
+
+ If a preset dictionary is needed after this call (see inflateSetDictionary
+ below), inflate sets strm->adler to the Adler-32 checksum of the dictionary
+ chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
+ strm->adler to the Adler-32 checksum of all output produced so far (that is,
+ total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
+ below. At the end of the stream, inflate() checks that its computed adler32
+ checksum is equal to that saved by the compressor and returns Z_STREAM_END
+ only if the checksum is correct.
+
+ inflate() can decompress and check either zlib-wrapped or gzip-wrapped
+ deflate data. The header type is detected automatically, if requested when
+ initializing with inflateInit2(). Any information contained in the gzip
+ header is not retained, so applications that need that information should
+ instead use raw inflate, see inflateInit2() below, or inflateBack() and
+ perform their own processing of the gzip header and trailer. When processing
+ gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
+ producted so far. The CRC-32 is checked against the gzip trailer.
+
+ inflate() returns Z_OK if some progress has been made (more input processed
+ or more output produced), Z_STREAM_END if the end of the compressed data has
+ been reached and all uncompressed output has been produced, Z_NEED_DICT if a
+ preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
+ corrupted (input stream not conforming to the zlib format or incorrect check

+ inflate() can be called again with more input and more output space to

+
+ This is another version of deflateInit with more compression options. The
+ fields next_in, zalloc, zfree and opaque must be initialized before by the
+ caller.
+
+ The method parameter is the compression method. It must be Z_DEFLATED in
+ this version of the library.
+
+ The windowBits parameter is the base two logarithm of the window size
+ (the size of the history buffer). It should be in the range 8..15 for this
+ version of the library. Larger values of this parameter result in better
+ compression at the expense of memory usage. The default value is 15 if
+ deflateInit is used instead.
+
+ windowBits can also be -8..-15 for raw deflate. In this case, -windowBits
+ determines the window size. deflate() will then generate raw deflate data
+ with no zlib header or trailer, and will not compute an adler32 check value.
+
+ windowBits can also be greater than 15 for optional gzip encoding. Add
+ 16 to windowBits to write a simple gzip header and trailer around the
+ compressed data instead of a zlib wrapper. The gzip header will have no
+ file name, no extra data, no comment, no modification time (set to zero), no
+ header crc, and the operating system will be set to 255 (unknown). If a
+ gzip stream is being written, strm->adler is a crc32 instead of an adler32.
+
+ The memLevel parameter specifies how much memory should be allocated
+ for the internal compression state. memLevel=1 uses minimum memory but is
+ slow and reduces compression ratio; memLevel=9 uses maximum memory for
+ optimal speed. The default value is 8. See zconf.h for total memory usage
+ as a function of windowBits and memLevel.
+
+ The strategy parameter is used to tune the compression algorithm. Use the
+ value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+ filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
+ string match), or Z_RLE to limit match distances to one (run-length
+ encoding). Filtered data consists mostly of small values with a somewhat
+ random distribution. In this case, the compression algorithm is tuned to
+ compress them better. The effect of Z_FILTERED is to force more Huffman
+ coding and less string matching; it is somewhat intermediate between
+ Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as
+ fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The
+ strategy parameter only affects the compression ratio but not the
+ correctness of the compressed output even if it is not set appropriately.
+ Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
+ decoder for special applications.
+
+ deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough

+ buffer. inflate() can be faster on modern CPUs when used with large
+ buffers. inflateBack() trusts the application to not change the output
+ buffer passed by the output function, at least until inflateBack() returns.
+
+ inflateBackInit() must be called first to allocate the internal state
+ and to initialize the state with the user-provided window buffer.
+ inflateBack() may then be used multiple times to inflate a complete, raw
+ deflate stream with each call. inflateBackEnd() is then called to free the
+ allocated state.
+
+ A raw deflate stream is one with no zlib or gzip header or trailer.
+ This routine would normally be used in a utility that reads zip or gzip
+ files and writes out uncompressed files. The utility would decode the
+ header and process the trailer on its own, hence this routine expects only
+ the raw deflate stream to decompress. This is different from the normal
+ behavior of inflate(), which expects either a zlib or gzip header and
+ trailer around the deflate stream.
+
+ inflateBack() uses two subroutines supplied by the caller that are then
+ called by inflateBack() for input and output. inflateBack() calls those
+ routines until it reads a complete deflate stream and writes out all of the
+ uncompressed data, or until it encounters an error. The function's
+ parameters and return types are defined above in the in_func and out_func
+ typedefs. inflateBack() will call in(in_desc, &buf) which should return the
+ number of bytes of provided input, and a pointer to that input in buf. If
+ there is no input available, in() must return zero--buf is ignored in that
+ case--and inflateBack() will return a buffer error. inflateBack() will call
+ out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out()
+ should return zero on success, or non-zero on failure. If out() returns
+ non-zero, inflateBack() will return with an error. Neither in() nor out()
+ are permitted to change the contents of the window provided to
+ inflateBackInit(), which is also the buffer that out() uses to write from.
+ The length written by out() will be at most the window size. Any non-zero
+ amount of input may be provided by in().
+
+ For convenience, inflateBack() can be provided input on the first call by
+ setting strm->next_in and strm->avail_in. If that input is exhausted, then
+ in() will be called. Therefore strm->next_in must be initialized before
+ calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called
+ immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in
+ must also be initialized, and then if strm->avail_in is not zero, input will
+ initially be taken from strm->next_in[0 .. strm->avail_in - 1].
+
+ The in_desc and out_desc parameters of inflateBack() is passed as the
+ first parameter of in() and out() respectively when they are called. These
+ descriptors can be optionally used to pass any information that the caller-
+ supplied in() and out() functions need to do their job.
+
+ On return, inflateBack() will set strm->next_in and strm->avail_in to
+ pass back any unused input that was provided by the last in() call. The
+ return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+ if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+ in the deflate stream (in which case strm->msg is set to indicate the nature
+ of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+ In the case of Z_BUF_ERROR, an input or output error can be distinguished
+ using strm->next_in which will be Z_NULL only if in() returned an error. If
+ strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+ non-zero. (in() will always be called before out(), so strm->next_in is

+ request transparent writing or appending with no compression and not using
+ the gzip format.
+
+ "a" can be used instead of "w" to request that the gzip stream that will
+ be written be appended to the file. "+" will result in an error, since
+ reading and writing to the same gzip file is not supported. The addition of
+ "x" when writing will create the file exclusively, which fails if the file
+ already exists. On systems that support it, the addition of "e" when
+ reading or writing will set the flag to close the file on an execve() call.
+
+ These functions, as well as gzip, will read and decode a sequence of gzip
+ streams in a file. The append function of gzopen() can be used to create
+ such a file. (Also see gzflush() for another way to do this.) When
+ appending, gzopen does not test whether the file begins with a gzip stream,
+ nor does it look for the end of the gzip streams to begin appending. gzopen
+ will simply append a gzip stream to the existing file.
+
+ gzopen can be used to read a file which is not in gzip format; in this
+ case gzread will directly read from the file without decompression. When
+ reading, this will be detected automatically by looking for the magic two-
+ byte gzip header.
+
+ gzopen returns NULL if the file could not be opened, if there was
+ insufficient memory to allocate the gzFile state, or if an invalid mode was
+ specified (an 'r', 'w', or 'a' was not provided, or '+' was provided).
