-ZLIB DATA COMPRESSION LIBRARY
-
-zlib 1.2.11 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 , or to Gilles Vollant
- 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 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 1.2.11 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 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 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 , 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/

-/*
- * 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.

- *
- * Analysis: The longest fixed codes are a length code of 8 bits plus 5
- * extra bits, for lengths 131 to 257. The longest fixed distance codes are
- * 5 bits plus 13 extra bits, for distances 16385 to 32768. The longest
- * possible fixed-codes length/distance pair is then 31 bits total.
- *
- * sym_buf starts one-fourth of the way into pending_buf. So there are
- * three bytes in sym_buf for every four bytes in pending_buf. Each symbol
- * in sym_buf is three bytes -- two for the distance and one for the
- * literal/length. As each symbol is consumed, the pointer to the next
- * sym_buf value to read moves forward three bytes. From that symbol, up to
- * 31 bits are written to pending_buf. The closest the written pending_buf
- * bits gets to the next sym_buf symbol to read is just before the last
- * code is written. At that time, 31*(n-2) bits have been written, just
- * after 24*(n-2) bits have been consumed from sym_buf. sym_buf starts at
- * 8*n bits into pending_buf. (Note that the symbol buffer fills when n-1
- * symbols are written.) The closest the writing gets to what is unread is
- * then n+14 bits. Here n is lit_bufsize, which is 16384 by default, and
- * can range from 128 to 32768.
- *
- * Therefore, at a minimum, there are 142 bits of space between what is
- * written and what is read in the overlain buffers, so the symbols cannot
- * be overwritten by the compressed data. That space is actually 139 bits,
- * due to the three-bit fixed-code block header.
- *
- * That covers the case where either Z_FIXED is specified, forcing fixed
- * codes, or when the use of fixed codes is chosen, because that choice
- * results in a smaller compressed block than dynamic codes. That latter
- * condition then assures that the above analysis also covers all dynamic
- * blocks. A dynamic-code block will only be chosen to be emitted if it has
- * fewer bits than a fixed-code block would for the same set of symbols.
- * Therefore its average symbol length is assured to be less than 31. So
- * the compressed data for a dynamic block also cannot overwrite the
- * symbols from which it is being constructed.

- strm provides the memory allocation functions and window buffer on input,

- returns, strm will also provide an error message.
-
- 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.
- inflateBack() can also return Z_STREAM_ERROR if the input parameters
- are not correct, i.e. strm is Z_NULL or the state was not initialized.

- 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.

-
-/*
- * 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.

- Process a set of code lengths to create a canonical Huffman code. The
- code lengths are lens[0..codes-1]. Each length corresponds to the
- symbols 0..codes-1. The Huffman code is generated by first sorting the
- symbols by length from short to long, and retaining the symbol order
- for codes with equal lengths. Then the code starts with all zero bits
- for the first code of the shortest length, and the codes are integer
- increments for the same length, and zeros are appended as the length
- increases. For the deflate format, these bits are stored backwards
- from their more natural integer increment ordering, and so when the
- decoding tables are built in the large loop below, the integer codes
- are incremented backwards.
-
- This routine assumes, but does not check, that all of the entries in
- lens[] are in the range 0..MAXBITS. The caller must assure this.
- 1..MAXBITS is interpreted as that code length. zero means that that
- symbol does not occur in this code.
-
- The codes are sorted by computing a count of codes for each length,
- creating from that a table of starting indices for each length in the
- sorted table, and then entering the symbols in order in the sorted
- table. The sorted table is work[], with that space being provided by
- the caller.
-
- The length counts are used for other purposes as well, i.e. finding
- the minimum and maximum length codes, determining if there are any
- codes at all, checking for a valid set of lengths, and looking ahead
- at length counts to determine sub-table sizes when building the

-
- 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
- of the low root bits of huff. This is saved in low to check for when a
- new sub-table should be started. drop is zero when the root table is
- being filled, and drop is root when sub-tables are being filled.
-
- 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.
-

- * ALGORITHM
- *
- * The "deflation" process uses several Huffman trees. The more
- * common source values are represented by shorter bit sequences.
- *
- * Each code tree is stored in a compressed form which is itself
- * a Huffman encoding of the lengths of all the code strings (in
- * ascending order by source values). The actual code strings are
- * reconstructed from the lengths in the inflate process, as described
- * in the deflate specification.

- Decompresses the source buffer into the destination buffer. *sourceLen is
- the byte length of the source buffer. Upon entry, *destLen is the total size
- of the destination buffer, which must be large enough to hold the entire
- uncompressed data. (The size of the uncompressed data must have been saved
- previously by the compressor and transmitted to the decompressor by some
- mechanism outside the scope of this compression library.) Upon exit,
- *destLen is the size of the decompressed data and *sourceLen is the number
- of source bytes consumed. Upon return, source + *sourceLen points to the
- first unused input byte.
-
- uncompress returns Z_OK if success, Z_MEM_ERROR if there was not enough
- memory, Z_BUF_ERROR if there was not enough room in the output buffer, or
- Z_DATA_ERROR if the input data was corrupted, including if the input data is

- Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
- x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
-
- 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.

- 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 and raw deflate streams in
- memory as well.
-
- The zlib format was designed to be compact and fast for use in memory
- and on communications channels. The gzip format was designed for single-
- file compression on file systems, has a larger header than zlib to maintain
- directory information, and uses a different, slower check method than zlib.
-
- 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 the case of corrupted input.

- to zero. The application must initialize zalloc, zfree and opaque before
- calling the init function. All other fields are set by the compression
- library and must not be updated by the application.
-
- The opaque value provided by the application will be passed as the first
- parameter for calls of zalloc and zfree. This can be useful for custom
- memory management. The compression library attaches no meaning to the
- opaque value.
-
- zalloc must return Z_NULL if there is not enough memory for the object.
- If zlib is used in a multi-threaded application, zalloc and zfree must be
- thread safe. In that case, zlib is thread-safe. When zalloc and zfree are
- Z_NULL on entry to the initialization function, they are set to internal
- routines that use the standard library functions malloc() and free().
-
- On 16-bit systems, the functions zalloc and zfree must be able to allocate
- exactly 65536 bytes, but will not be required to allocate more than this if
- the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS, pointers
- returned by zalloc for objects of exactly 65536 bytes *must* have their
- offset normalized to zero. The default allocation function provided by this
- library ensures this (see zutil.c). To reduce memory requirements and avoid
- any allocation of 64K objects, at the expense of compression ratio, compile
- the library with -DMAX_WBITS=14 (see zconf.h).
-
- The fields total_in and total_out can be used for statistics or progress
- reports. After compression, total_in holds the total size of the
- uncompressed data and may be saved for use by the decompressor (particularly
- if the decompressor wants to decompress everything in a single step).

-ZEXTERN int ZEXPORT deflate OF((z_streamp strm, int flush));
-/*
- 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().
-
- - Generate 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. Some output may be provided even if
- flush is zero.
-
- 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. See deflatePending(),
- which can be used if desired to determine whether or not there is more ouput
- in that case.
-
- 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
- codes 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 or Z_BUF_ERROR, 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 in the first deflate call after deflateInit if all the
- compression is to be done in a single step. In order to complete in one
- call, 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 Adler-32 checksum of all input read
- so far (that is, total_in bytes). If a gzip stream is being generated, then
- strm->adler will be the CRC-32 checksum of the input read so far. (See
- deflateInit2 below.)
-
- deflate() may update strm->data_type if it can make a good guess about
- the input data type (Z_BINARY or Z_TEXT). If 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 or the state was inadvertently written over
- by the application), or Z_BUF_ERROR if no progress is possible (for example
- avail_in or avail_out was zero). Note that Z_BUF_ERROR is not fatal, and
- deflate() can be called again with more input and more output space to

- inflate decompresses as much data as possible, and stops when the input

- 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), then next_in and avail_in are updated

- - Generate 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. If the
- caller of inflate() does not provide both available input and available
- output space, it is possible that there will be no progress made. 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.
-
- 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.
- To assist in this, on return inflate() always sets 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 Adler-32
- 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 unless inflateGetHeader() is used. When processing
- gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output
- produced so far. The CRC-32 is checked against the gzip trailer, as is the
- uncompressed length, modulo 2^32.
-
- 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
- value, in which case strm->msg points to a string with a more specific
- error), Z_STREAM_ERROR if the stream structure was inconsistent (for example
- next_in or next_out was Z_NULL, or the state was inadvertently written over
- by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR
- if no progress was possible or if there was not enough room in the output
- buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and
- inflate() can be called again with more input and more output space to
- continue decompressing. If Z_DATA_ERROR is returned, the application may
- then call inflateSync() to look for a good compression block if a partial
- recovery of the data is to be attempted.

-ZEXTERN int ZEXPORT deflateInit2 OF((z_streamp strm,
- int level,
- int method,
- int windowBits,
- int memLevel,
- int strategy));
-
- 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.
-
- For the current implementation of deflate(), a windowBits value of 8 (a
- window size of 256 bytes) is not supported. As a result, a request for 8
- will result in 9 (a 512-byte window). In that case, providing 8 to
- inflateInit2() will result in an error when the zlib header with 9 is
- checked against the initialization of inflate(). The remedy is to not use 8
- with deflateInit2() with this initialization, or at least in that case use 9
- with inflateInit2().
-
- 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 a 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 the appropriate value,
- if the operating system was determined at compile time. If a gzip stream is
- being written, strm->adler is a CRC-32 instead of an Adler-32.
-
- For raw deflate or gzip encoding, a request for a 256-byte window is
- rejected as invalid, since only the zlib header provides a means of
- transmitting the window size to the decompressor.
-
- 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
- memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
- method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
- incompatible with the version assumed by the caller (ZLIB_VERSION). msg is
- set to null if there is no error message. deflateInit2 does not perform any
- compression: this will be done by deflate().

- Initializes the compression dictionary from the given byte sequence

- function must be called either before any call of deflate, or immediately
- after the completion of a deflate block, i.e. after all input has been
- consumed and all output has been delivered when using any of the flush
- options Z_BLOCK, Z_PARTIAL_FLUSH, Z_SYNC_FLUSH, or Z_FULL_FLUSH. The

- inflateSetDictionary).
-
- The dictionary should consist of strings (byte sequences) that are likely
- to be encountered later in the data to be compressed, with the most commonly
- used strings preferably put towards the end of the dictionary. Using a
- dictionary is most useful when the data to be compressed is short and can be
- predicted with good accuracy; the data can then be compressed better than
- with the default empty dictionary.
-
- Depending on the size of the compression data structures selected by
- deflateInit or deflateInit2, a part of the dictionary may in effect be
- discarded, for example if the dictionary is larger than the window size
- provided in deflateInit or deflateInit2. Thus the strings most likely to be

- used to switch between compression and straight copy of the input data, or
- to switch to a different kind of input data requiring a different strategy.
- If the compression approach (which is a function of the level) or the
- strategy is changed, and if any input has been consumed in a previous
- deflate() call, then the input available so far is compressed with the old
- level and strategy using deflate(strm, Z_BLOCK). There are three approaches
- for the compression levels 0, 1..3, and 4..9 respectively. The new level
- and strategy will take effect at the next call of deflate().
-
- If a deflate(strm, Z_BLOCK) is performed by deflateParams(), and it does
- not have enough output space to complete, then the parameter change will not
- take effect. In this case, deflateParams() can be called again with the
- same parameters and more output space to try again.
-
- In order to assure a change in the parameters on the first try, the
- deflate stream should be flushed using deflate() with Z_BLOCK or other flush
- request until strm.avail_out is not zero, before calling deflateParams().
- Then no more input data should be provided before the deflateParams() call.
- If this is done, the old level and strategy will be applied to the data
- compressed before deflateParams(), and the new level and strategy will be
- applied to the the data compressed after deflateParams().
-
- deflateParams returns Z_OK on success, Z_STREAM_ERROR if the source stream
- state was inconsistent or if a parameter was invalid, or Z_BUF_ERROR if
- there was not enough output space to complete the compression of the

- inflateBack() does a raw inflate with a single call using a call-back
- interface for input and output. This is potentially more efficient than
- inflate() for file i/o applications, in that it avoids copying between the
- output and the sliding window by simply making the window itself the output
- 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 default
- behavior of inflate(), which expects a zlib 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
- assured to be defined if out() returns non-zero.) Note that inflateBack()

-
- Opens a gzip (.gz) file for reading or writing. The mode parameter is as
- in fopen ("rb" or "wb") but can also include a compression level ("wb9") or
- a strategy: 'f' for filtered data as in "wb6f", 'h' for Huffman-only
- compression as in "wb1h", 'R' for run-length encoding as in "wb1R", or 'F'
- for fixed code compression as in "wb9F". (See the description of
- deflateInit2 for more information about the strategy parameter.) 'T' will
- 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).
- errno can be checked to determine if the reason gzopen failed was that the
