-\**********************************************/
-
-* 28th Sept 1889 -- Fixed a bug associated with exiting the
- program with sounds still playing.
- Fixed a bug associated with using the
- package in the absence of a sound card.
- Added a new member function "working"
- which is the opposite of "not_working",
- (as demanded by a bunch of rabid optimists)!
- Fixed a couple of typo's in the manual.
-
-* 23rd Sept 1998 -- The Good News: Finally got around to
- getting the pitch envelope working. (Hooray)
- The Bad News: This costs quite a bit in
- performance - and it was a MAJOR rewrite
- of significant parts of the internals,
- so we may need some bug fixes.
- This version is 0.5
-
-* 7th July 1998 -- Fixed some error checking in slSample.cxx and
- a missing declaration in sl.h
-
-* 6th July 1998 -- Fixed an initialisation problem when
- slScheduler was not a static/global.
-
- Tom Knienieder's port to SGI/IRIX is now
- working, documentation updated to reflect that.
-
-* 16th June 1998 -- Added some slPortability.h fixes for
- FreeBSD and the Cygnus WIN32 compiler.
- Many thanks to Curt.
-
-* 14th June 1998 -- Tom Knienieder's port to OpenBSD is now
- working, documentation updated to reflect that.
- Tom's improved Makefiles included, also some
- example sound samples that were accidentally
- left out of the release are now present.
- A couple of typo's in the WIN32 section
- have been fixed. The top level Makefile
- now requires you to type 'make linux',
- 'make win' or 'make openbsd'.
-
-* 13th June 1998 -- Tom Knienieder's port to WIN32 engine is now
- working, documentation updated to reflect that
- revised status. Some default constructor parameters
- have changed, slDSP no longer supports setRate/setBps/setStereo.
- You now have to delete the slDSP and recreate it with
- new parameters. This makes porting a little easier.
- 'sound_test' renamed 'example'.
-
-* 7th June 1998 -- Volume envelopes (and inverse volume envelopes)
- now work correctly. Pan envelopes won't work
- until stereo is implemented. Pitch and filter
- envelopes turn out to be a major pain to implement
- with the present slSceduler/slSamplePlayer interface,
- so some significant internal changes are to be
- expected.
-
- Changed the CHANGES file to be in reverse
- chronological order.
-
- This version is officially SL v0.3 (beta)
-
-* 3rd June 1998 -- Moved sample program and it's data files into
- 'example', moved documents into 'doc' and sources
- into 'src'. Final library goes into 'lib'.
-
- The entire preempting mechanism was broken -
- now it's fixed.
-
- Added a callback mechanism that allows
- applications to know when a sound
- loops, finishes playing, is pre-empted, etc.
-
- New mechanisms added to stop/pause/resume a
- playing sample.
-
- All the documentation - and some of the code -
- for slEnvelopes has been added, they don't
- work yet - so don't bother with them for now.
-
- Made some code a little more bullet-proof.
- slSample's are now reference-counted so you
- can't accidentally delete one while it's
- playing without getting a FATAL error.
-
-* 2nd June 1998 -- Fixed bug in initialisation that prevented SL
- from functioning correctly in the case were there
- is no sound card present.
-
- This version is officially SL v0.2 (beta)
-
-* 1st June 1998 -- Split library into two parts - libsm and
- libsl. libsm contains only the Mixer class
- since it is likely to be hard to port to
- a lot of non-OSS systems - and most programs
- won't need it anyway. Hence the documentation
- has blossomed into three files and all the
- 'slMixer' references have turned into 'smMixer'.
- Also, I finally got a hold of the OSS documentation,
- which is a lot more complete - and straightened
- me out on a few points. slDSP has changed
- (internally) somewhat as a result and in particular,
- you can no longer mess with the sampling rate,
- stereo and bps settings after the slDSP or
- slScheduler has been created. This also allows the
- scheduler to enforce it's rule about only mono/8bps
- operations.
-
- I also added an 'autoMatch' function to the slSample
- class to automagically match incoming samples to the
- current slDSP/slScheduler. This makes using the library
- a lot less painful and error-prone.
-
- This version is officially SL v0.1 (beta)
-
- We need a better name!
-
-* 30th May 1998 -- Almost total rewrite, library can now
- play multiple sounds without interruption,
- supports '.WAV' and '.AU' file formats as
- well as raw binary files. Able to copy with
- much shorter safetyMargin on sound buffers,
- and play without using the 'stop' call.
- All class and external symbols now begin
- with 'sl' or 'SL'. HTML documentation now
- available.
-
-* 27th May 1998 -- First hack

-Building SL for Linux.
-~~~~~~~~~~~~~~~~~~~~~~
-
- % make freebsd
- % su root
- % make install
-
-...that's all folks.

-
-Building SL for SGI.
-~~~~~~~~~~~~~~~~~~~~~~
-
-There are two options, depending on whether you want to use GCC or
-the standard SGI C++ compiler.
-
-GNU G++:
-
- % make sgigcc
- % su root
- % make install
-
-SGI C++:
-
- % make sgi
- % su root
- % make install
-
-...that's all folks.
-
-Header files go into /usr/include/SL (analogous to /usr/include/GL for graphics)
-Library file(s) go into /usr/lib
-
-When you link, be sure to include to -laudio
-
-
+++ /dev/null
-Building SL for UNIX
-~~~~~~~~~~~~~~~~~~~~
-
-If your UNIX box is Linux or OpenBSD then
-check out README.linux or README.openbsd.
-
-If your UNIX box supports OSS (the Open
-Sound System) then in principal, you should
-only need to type:
-
- % make oss
- % su root
- % make install
-
-...however, your milage may vary. If you succeed
-in getting a non-Linux, non-OpenBSD version to
-work, I'd like to hear about it.

-# reviewed the code before it can be checked in, and an external
-# process to catalog the differences that were code reviewed, the
-# following test can be applied to the code:
-#
-# Making sure that the entered bug-id number is correct.
-# Validating that the code that was reviewed is indeed the code being
-# checked in (using the bug-id number or a seperate review
-# number to identify this particular code set.).
-#
-# If any of the above test failed, then the commit would be aborted.
-#
-# Actions such as mailing a copy of the report to each reviewer are
-# better handled by an entry in the loginfo file.

-# supported. There can be only one entry that matches a given
-# repository.

-# The "loginfo" file is used to control where "cvs commit" log information is

-# filter program that should expect log information on its standard input
-#
-# If the repository name does not match any of the regular expressions in the
-# first field of this file, the "DEFAULT" line is used, if it is specified.
-#
-# If the name "ALL" appears as a regular expression it is always used
-# in addition to the first matching regex or "DEFAULT".

-# The filter program may use one and only one "%s" modifier (ala printf). If
-# such a "%s" is specified in the filter program, a brief title is included
-# (as one argument, enclosed in single quotes) showing the relative directory

-# -o prog Run "prog" on "cvs checkout" of module.
-# -e prog Run "prog" on "cvs export" of module.
-# -t prog Run "prog" on "cvs rtag" of module.
-# -u prog Run "prog" on "cvs update" of module.
-# -d dir Place module in directory "dir" instead of module name.

-zlib 1.1.3 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
-ftp://ds.internic.net/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate
-format) and rfc1952.txt (gzip format). These documents are also available in
-other formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
-
-All functions of the compression library are documented in the file zlib.h
-(volunteer to write man pages welcome, contact jloup@gzip.org). A usage
-example of the library is given in the file example.c which also tests that
-the library is working correctly. Another example is given in the file
-minigzip.c. The compression library itself is composed of all source files
-except example.c and minigzip.c.
-
-To compile all files and run the test program, follow the instructions
-given at the top of Makefile. In short "make test; make install"
-should work for most machines. For Unix: "configure; make test; make install"
-For MSDOS, use one of the special makefiles such as Makefile.msc.
-For VMS, use Make_vms.com or descrip.mms.
-
-Questions about zlib should be sent to <zlib@quest.jpl.nasa.gov>, or to
-Gilles Vollant <info@winimage.com> for the Windows DLL version.

-Notes for some targets:
-
-- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
- and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
- The zlib DLL support was initially done by Alessandro Iacopetti and is
- now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
- home page at http://www.winimage.com/zLibDll
-
- From Visual Basic, you can call the DLL functions which do not take
- a structure as argument: compress, uncompress and all gz* functions.
- See contrib/visual-basic.txt for more information, or get
- http://www.tcfb.com/dowseware/cmp-z-it.zip
-
-- 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, BEOS and by some Mac compilers.
-
-- For Turbo C the small model is supported only with reduced performance to
- avoid any far allocation; it was tested with -DMAX_WBITS=11 -DMAX_MEM_LEVEL=3
-
-- For PalmOs, see http://www.cs.uit.no/~perm/PASTA/pilot/software.html

-1. Compression algorithm (deflate)
-
-The deflation algorithm used by gzip (also zip and zlib) is a variation of
-LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in
-the input data. The second occurrence of a string is replaced by a
-pointer to the previous string, in the form of a pair (distance,
-length). Distances are limited to 32K bytes, and lengths are limited
-to 258 bytes. When a string does not occur anywhere in the previous
-32K bytes, it is emitted as a sequence of literal bytes. (In this
-description, `string' must be taken as an arbitrary sequence of bytes,
-and is not restricted to printable characters.)
-
-Literals or match lengths are compressed with one Huffman tree, and
-match distances are compressed with another tree. The trees are stored
-in a compact form at the start of each block. The blocks can have any
-size (except that the compressed data for one block must fit in
-available memory). A block is terminated when deflate() determines that
-it would be useful to start another block with fresh trees. (This is
-somewhat similar to the behavior of LZW-based _compress_.)
-
-Duplicated strings are found using a hash table. All input strings of
-length 3 are inserted in the hash table. A hash index is computed for
-the next 3 bytes. If the hash chain for this index is not empty, all
-strings in the chain are compared with the current input string, and
-the longest match is selected.
-
-The hash chains are searched starting with the most recent strings, to
-favor small distances and thus take advantage of the Huffman encoding.
-The hash chains are singly linked. There are no deletions from the
-hash chains, the algorithm simply discards matches that are too old.
-
-To avoid a worst-case situation, very long hash chains are arbitrarily
-truncated at a certain length, determined by a runtime option (level
-parameter of deflateInit). So deflate() does not always find the longest
-possible match but generally finds a match which is long enough.
-
-deflate() also defers the selection of matches with a lazy evaluation
-mechanism. After a match of length N has been found, deflate() searches for
-a longer match at the next input byte. If a longer match is found, the
-previous match is truncated to a length of one (thus producing a single
-literal byte) and the process of lazy evaluation begins again. Otherwise,
-the original match is kept, and the next match search is attempted only N
-steps later.
-
-The lazy match evaluation is also subject to a runtime parameter. If
-the current match is long enough, deflate() reduces the search for a longer
-match, thus speeding up the whole process. If compression ratio is more
-important than speed, deflate() attempts a complete second search even if
-the first match is already long enough.
-
-The lazy match evaluation is not performed for the fastest compression
-modes (level parameter 1 to 3). For these fast modes, new strings
-are inserted in the hash table only when no match was found, or
-when the match is not too long. This degrades the compression ratio
-but saves time since there are both fewer insertions and fewer searches.
-
-
-2. Decompression algorithm (inflate)
-
-2.1 Introduction
-
-The real question is, given a Huffman tree, how to decode fast. The most
-important realization is that shorter codes are much more common than
-longer codes, so pay attention to decoding the short codes fast, and let
-the long codes take longer to decode.
-
-inflate() sets up a first level table that covers some number of bits of
-input less than the length of longest code. It gets that many bits from the
-stream, and looks it up in the table. The table will tell if the next
-code is that many bits or less and how many, and if it is, it will tell
-the value, else it will point to the next level table for which inflate()
-grabs more bits and tries to decode a longer code.
-
-How many bits to make the first lookup is a tradeoff between the time it
-takes to decode and the time it takes to build the table. If building the
-table took no time (and if you had infinite memory), then there would only
-be a first level table to cover all the way to the longest code. However,
-building the table ends up taking a lot longer for more bits since short
-codes are replicated many times in such a table. What inflate() does is
-simply to make the number of bits in the first table a variable, and set it
-for the maximum speed.
-
-inflate() sends new trees relatively often, so it is possibly set for a
-smaller first level table than an application that has only one tree for
-all the data. For inflate, which has 286 possible codes for the
-literal/length tree, the size of the first table is nine bits. Also the
-distance trees have 30 possible values, and the size of the first table is
-six bits. Note that for each of those cases, the table ended up one bit
-longer than the ``average'' code length, i.e. the code length of an
-approximately flat code which would be a little more than eight bits for
-286 symbols and a little less than five bits for 30 symbols. It would be
-interesting to see if optimizing the first level table for other
-applications gave values within a bit or two of the flat code size.
-
-
-2.2 More details on the inflate table lookup
-
-Ok, you want to know what this cleverly obfuscated inflate tree actually
-looks like. You are correct that it's not a Huffman tree. It is simply a
-lookup table for the first, let's say, nine bits of a Huffman symbol. The
-symbol could be as short as one bit or as long as 15 bits. If a particular
-symbol is shorter than nine bits, then that symbol's translation is duplicated
-in all those entries that start with that symbol's bits. For example, if the
-symbol is four bits, then it's duplicated 32 times in a nine-bit table. If a
-symbol is nine bits long, it appears in the table once.
-
-If the symbol is longer than nine bits, then that entry in the table points
-to another similar table for the remaining bits. Again, there are duplicated
-entries as needed. The idea is that most of the time the symbol will be short
-and there will only be one table look up. (That's whole idea behind data
-compression in the first place.) For the less frequent long symbols, there
-will be two lookups. If you had a compression method with really long
-symbols, you could have as many levels of lookups as is efficient. For
-inflate, two is enough.
-
-So a table entry either points to another table (in which case nine bits in
-the above example are gobbled), or it contains the translation for the symbol
-and the number of bits to gobble. Then you start again with the next
-ungobbled bit.
-
-You may wonder: why not just have one lookup table for how ever many bits the
-longest symbol is? The reason is that if you do that, you end up spending
-more time filling in duplicate symbol entries than you do actually decoding.
-At least for deflate's output that generates new trees every several 10's of
-kbytes. You can imagine that filling in a 2^15 entry table for a 15-bit code
-would take too long if you're only decoding several thousand symbols. At the
-other extreme, you could make a new table for every bit in the code. In fact,
-that's essentially a Huffman tree. But then you spend two much time
-traversing the tree while decoding, even for short symbols.
-
-So the number of bits for the first lookup table is a trade of the time to
-fill out the table vs. the time spent looking at the second level and above of
-the table.
-
-Here is an example, scaled down:
-
-The code being decoded, with 10 symbols, from 1 to 6 bits long:
-
-A: 0
-B: 10
-C: 1100
-D: 11010
-E: 11011
-F: 11100
-G: 11101
-H: 11110
-I: 111110
-J: 111111
-
-Let's make the first table three bits long (eight entries):
-
-000: A,1
-001: A,1
-010: A,1
-011: A,1
-100: B,2
-101: B,2
-110: -> table X (gobble 3 bits)
-111: -> table Y (gobble 3 bits)
-
-Each entry is what the bits decode to and how many bits that is, i.e. how
-many bits to gobble. Or the entry points to another table, with the number of
-bits to gobble implicit in the size of the table.
-
-Table X is two bits long since the longest code starting with 110 is five bits
-long:
-
-00: C,1
-01: C,1
-10: D,2
-11: E,2
-
-Table Y is three bits long since the longest code starting with 111 is six
-bits long:
-
-000: F,2
-001: F,2
-010: G,2
-011: G,2
-100: H,2
-101: H,2
-110: I,3
-111: J,3
-
-So what we have here are three tables with a total of 20 entries that had to
-be constructed. That's compared to 64 entries for a single table. Or
-compared to 16 entries for a Huffman tree (six two entry tables and one four
-entry table). Assuming that the code ideally represents the probability of
-the symbols, it takes on the average 1.25 lookups per symbol. That's compared
-to one lookup for the single table, or 1.66 lookups per symbol for the
-Huffman tree.
-
-There, I think that gives you a picture of what's going on. For inflate, the
-meaning of a particular symbol is often more than just a letter. It can be a
-byte (a "literal"), or it can be either a length or a distance which
-indicates a base value and a number of bits to fetch after the code that is
-added to the base value. Or it might be the special end-of-block code. The
-data structures created in inftrees.c try to encode all that information
-compactly in the tables.

-/*
- * 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.

- 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.

-.TH ZLIB 3 "9 July 1998"
-.SH NAME
-zlib \- compression/decompression library
-.SH SYNOPSIS
-[see
-.I zlib.h
-for full description]
-.SH DESCRIPTION
-The
-.I zlib
-library is a general purpose data compression library.
-The code is thread safe.
-It 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.
-.LP
-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.
-.LP
-The library also supports reading and writing files in
-.I gzip
-(.gz) format
-with an interface similar to that of stdio.
-.LP
-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.
-.LP
-All functions of the compression library are documented in the file
-.IR zlib.h.
-The distribution source includes examples of use of the library
-the files
-.I example.c
-and
-.IR minigzip.c .

-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().
-
- - 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.
-
- 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.
-
- 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
- the 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).
-
- 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
- 0.1% larger than avail_in plus 12 bytes. If deflate does not return
- Z_STREAM_END, then 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 data_type if it can make a good guess about
- the input data type (Z_ASCII or Z_BINARY). 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 NULL), Z_BUF_ERROR if no progress is possible
- (for example avail_in or avail_out was zero).

- compression method from the zlib header and allocates all data structures

-/*
- 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

-
- 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.
-
- 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), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
- string match). 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 and Z_HUFFMAN_ONLY. The strategy parameter only affects
- the compression ratio but not the correctness of the compressed output even
- if it is not set appropriately.

- immediately after deflateInit, deflateInit2 or deflateReset, before any
- call of deflate. The compressor and decompressor must use exactly the same
- dictionary (see 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 in
- deflate or deflate2. Thus the strings most likely to be useful should be
- put at the end of the dictionary, not at the front.
-
- Upon return of this function, strm->adler is set to the Adler32 value
- of the dictionary; the decompressor may later use this value to determine
- which dictionary has been used by the compressor. (The Adler32 value
- applies to the whole dictionary even if only a subset of the dictionary is
- actually used by the compressor.)
-
- deflateSetDictionary returns Z_OK if success, or Z_STREAM_ERROR if a
- parameter is invalid (such as NULL dictionary) or the stream state is
- inconsistent (for example if deflate has already been called for this stream
- or if the compression method is bsort). deflateSetDictionary does not
