Changes in 1.1.4 (11 March 2002)
|

Frequently Asked Questions about zlib
|
||||
|
||||
|
||||
If your question is not there, please check the zlib home page
|
||||
http://www.zlib.org which may have more recent information.
|
||||
The lastest zlib FAQ is at http://www.gzip.org/zlib/zlib_faq.html
|
||||
|
||||
|
||||
1. Is zlib Y2K-compliant?
|
||||
|
||||
Yes. zlib doesn't handle dates.
|
||||
|
||||
2. Where can I get a Windows DLL version?
|
||||
|
||||
The zlib sources can be compiled without change to produce a DLL. If you
|
||||
want a precompiled DLL, see http://www.winimage.com/zLibDll/ . Questions
|
||||
about the zlib DLL should be sent to Gilles Vollant (info@winimage.com).
|
||||
|
||||
3. Where can I get a Visual Basic interface to zlib?
|
||||
|
||||
See
|
||||
* http://www.winimage.com/zLibDll/cmp-z-it.zip
|
||||
* http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm
|
||||
* contrib/visual-basic.txt in the zlib distribution
|
||||
|
||||
4. compress() returns Z_BUF_ERROR
|
||||
|
||||
Make sure that before the call of compress, the length of the compressed
|
||||
buffer is equal to the total size of the compressed buffer and not
|
||||
zero. For Visual Basic, check that this parameter is passed by reference
|
||||
("as any"), not by value ("as long").
|
||||
|
||||
5. deflate() or inflate() returns Z_BUF_ERROR
|
||||
|
||||
Before making the call, make sure that avail_in and avail_out are not
|
||||
zero. When setting the parameter flush equal to Z_FINISH, also make sure
|
||||
that avail_out is big enough to allow processing all pending input.
|
||||
|
||||
6. Where's the zlib documentation (man pages, etc.)?
|
||||
|
||||
It's in zlib.h for the moment, and Francis S. Lin has converted it to a
|
||||
web page zlib.html. Volunteers to transform this to Unix-style man pages,
|
||||
please contact Jean-loup Gailly (jloup@gzip.org). Examples of zlib usage
|
||||
are in the files example.c and minigzip.c.
|
||||
|
||||
7. Why don't you use GNU autoconf or libtool or ...?
|
||||
|
||||
Because we would like to keep zlib as a very small and simple
|
||||
package. zlib is rather portable and doesn't need much configuration.
|
||||
|
||||
8. I found a bug in zlib.
|
||||
|
||||
Most of the time, such problems are due to an incorrect usage of
|
||||
zlib. Please try to reproduce the problem with a small program and send
|
||||
the corresponding source to us at zlib@gzip.org . Do not send
|
||||
multi-megabyte data files without prior agreement.
|
||||
|
||||
9. Why do I get "undefined reference to gzputc"?
|
||||
|
||||
If "make test" produces something like
|
||||
|
||||
example.o(.text+0x154): undefined reference to `gzputc'
|
||||
|
||||
check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
|
||||
/usr/X11R6/lib. Remove any old versions, then do "make install".
|
||||
|
||||
10. I need a Delphi interface to zlib.
|
||||
|
||||
See the directories contrib/delphi and contrib/delphi2 in the zlib
|
||||
distribution.
|
||||
|
||||
11. Can zlib handle .zip archives?
|
||||
|
||||
See the directory contrib/minizip in the zlib distribution.
|
||||
|
||||
12. Can zlib handle .Z files?
|
||||
|
||||
No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
|
||||
the code of uncompress on your own.
|
||||
|
||||
13. How can I make a Unix shared library?
|
||||
|
||||
make clean
|
||||
./configure -s
|
||||
make
|
||||
|
||||
14. Why does "make test" fail on Mac OS X?
|
||||
|
||||
Mac OS X already includes zlib as a shared library, and so -lz links the
|
||||
shared library instead of the one that the "make" compiled. For zlib
|
||||
1.1.3, the two are incompatible due to different compile-time
|
||||
options. Simply change the -lz in the Makefile to libz.a, and it will use
|
||||
the compiled library instead of the shared one and the "make test" will
|
||||
succeed.
|
||||
|
||||
15. I have a question about OttoPDF
|
||||
|
||||
We are not the authors of OttoPDF. The real author is on the OttoPDF web
|
||||
site Joel Hainley jhainley@myndkryme.com.

The only changes made since 1.1.3 are bug corrections:
|
||||
|
||||
- ZFREE was repeated on same allocation on some error conditions.
|
||||
This creates a security problem described in
|
||||
http://www.zlib.org/advisory-2002-03-11.txt
|
||||
- Returned incorrect error (Z_MEM_ERROR) on some invalid data
|
||||
- Avoid accesses before window for invalid distances with inflate window
|
||||
less than 32K.
|
||||
- force windowBits > 8 to avoid a bug in the encoder for a window size
|
||||
of 256 bytes. (A complete fix will be available in 1.1.5).
|
||||
|
||||
The beta version 1.1.5beta includes many more changes. A new official
|
||||
version 1.1.5 will be released as soon as extensive testing has been
|
||||
completed on it.
|
||||
|
||||
- fix gzseek which was broken in write mode
|
||||
- return error for gzseek to negative absolute position
|
||||
- fix configure for Linux (Chun-Chung Chen)
|
||||
- increase stack space for MSC (Tim Wegner)
|
||||
- get_crc_table and inflateSyncPoint are EXPORTed (Gilles Vollant)
|
||||
- define EXPORTVA for gzprintf (Gilles Vollant)
|
||||
- added mini man page zlib.3 (Rick Rodgers) [volunteers to write full

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

|

* Two optimization notes on the choice of instructions:
|

*
|
||||
* The first instruction uses a 16-bit address, which costs an extra,
|
||||
* unpairable cycle. This is cheaper than doing a 32-bit access and
|
||||
* zeroing the high word, due to the 3-cycle misalignment penalty which
|
||||
* would occur half the time. This also turns out to be cheaper than
|
||||
* doing two separate 8-bit accesses, as the memory is so rarely in the
|
||||
* L1 cache.
|
||||
*
|
||||
* The window buffer, however, apparently spends a lot of time in the
|
||||
* cache, and so it is faster to retrieve the word at the end of the
|
||||
* match string with two 8-bit loads. The instructions that test the
|
||||
* word at the beginning of the match string, however, are executed
|
||||
* much less frequently, and there it was cheaper to use 16-bit
|
||||
* instructions, which avoided the necessity of saving off and
|
||||
* subsequently reloading one of the other registers.

This is a patched version of zlib, modified to use
|
||||
Pentium-Pro-optimized assembly code in the deflation algorithm. The
|
||||
files changed/added by this patch are:
|
||||
|
||||
README.686
|
||||
match.S
|
||||
|
||||
The speedup that this patch provides varies, depending on whether the
|
||||
compiler used to build the original version of zlib falls afoul of the
|
||||
PPro's speed traps. My own tests show a speedup of around 10-20% at
|
||||
the default compression level, and 20-30% using -9, against a version
|
||||
compiled using gcc 2.7.2.3. Your mileage may vary.
|
||||
|
||||
Note that this code has been tailored for the PPro/PII in particular,
|
||||
and will not perform particuarly well on a Pentium.
|
||||
|
||||
If you are using an assembler other than GNU as, you will have to
|
||||
translate match.S to use your assembler's syntax. (Have fun.)

These are files used to compile zlib under Borland C++ Builder 3.
|
||||
|
||||
zlib.bpg is the main project group that can be loaded in the BCB IDE and
|
||||
loads all other *.bpr projects
|
||||
|
||||
zlib.bpr is a project used to create a static zlib.lib library with C calling
|
||||
convention for functions.
|
||||
|
||||
zlib32.bpr creates a zlib32.dll dynamic link library with Windows standard
|
||||
calling convention.
|
||||
|
||||
d_zlib.bpr creates a set of .obj files with register calling convention.
|
||||
These files are used by zlib.pas to create a Delphi unit containing zlib.
|
||||
The d_zlib.lib file generated isn't useful and can be deleted.
|
||||
|
||||
zlib.cpp, zlib32.cpp and d_zlib.cpp are used by the above projects.

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

stream will raise an exception. Using Seek to move the stream pointer
|

will raise an exception.

Output data is cached internally, written to the output stream only when

the internal output buffer is full. All pending output data is flushed

when the stream is destroyed.

The Position property returns the number of uncompressed bytes of

data that have been written to the stream so far.

CompressionRate returns the on-the-fly percentage by which the original

data has been compressed: (1 - (CompressedBytes / UncompressedBytes)) * 100

If raw data size = 100 and compressed data size = 25, the CompressionRate
|

is 75%
|

The OnProgress event is called each time the output buffer is filled and

written to the output stream. This is useful for updating a progress

indicator when you are writing a large chunk of data to the compression
|

stream in a single call.}

Compressed data comes from a separate source stream. TDecompressionStream
|
||||
is read-only and unidirectional; you can seek forward in the stream, but not
|
||||
backwards. The special case of setting the stream position to zero is
|
||||
allowed. Seeking forward decompresses data until the requested position in
|
||||
the uncompressed data has been reached. Seeking backwards, seeking relative
|
||||
to the end of the stream, requesting the size of the stream, and writing to
|
||||
the stream will raise an exception.
|

have been read from the stream so far.

compressed data is exhausted and the next block is read from the input stream.

This is useful for updating a progress indicator when you are reading a

large chunk of data from the decompression stream in a single call.}

// If your DLL uses VCL and exports any functions that pass VCL String objects

// results, you will need to build both your DLL project and any EXE projects

// DLL and its calling EXE's to use BORLNDMM.DLL as their memory manager. In

// these cases, the file BORLNDMM.DLL should be deployed along with your DLL
|

// and the RTL DLL (CP3240MT.DLL). To avoid the requiring BORLNDMM.DLL in

// these situations, pass string information using "char *" or ShortString

See probdesc.zip from PKWare for specification of .ZIP format.
|
||||
|
||||
What is Unzip
|
||||
The Zlib library support the deflate compression and the creation of gzip (.gz)
|
||||
file. Zlib is free and small.
|
||||
The .Zip format, which can contain several compressed files (.gz can containt
|
||||
only one file) is a very popular format. This is why I've written a package for reading file compressed in Zipfile.
|
||||
|
||||
Using Unzip package
|
||||
|
||||
You need source of Zlib (get zlib111.zip and read zlib.h).
|
||||
Get unzlb015.zip and read unzip.h (whith documentation of unzip functions)
|
||||
|
||||
The Unzip package is only two file : unzip.h and unzip.c. But it use the Zlib
|
||||
files.
|
||||
unztst.c is a simple sample program, which list file in a zipfile and display
|
||||
README.TXT or FILE_ID.DIZ (if these files are found).
|
||||
miniunz.c is a mini unzip program.
|
||||
|
||||
I'm also currenlyt writing a zipping portion (zip.h, zip.c and test with minizip.c)
|
||||
|
||||
Please email me for feedback.
|
||||
I hope my source is compatible with Unix system, but I need your help for be sure

/* unzip.h -- IO for uncompress .zip files using zlib
|
||||
Version 0.15 beta, Mar 19th, 1998,
|
||||
|
||||
Copyright (C) 1998 Gilles Vollant
|
||||
|
||||
This unzip package allow extract file from .ZIP file, compatible with PKZip 2.04g
|
||||
WinZip, InfoZip tools and compatible.
|
||||
Encryption and multi volume ZipFile (span) are not supported.
|
||||
Old compressions used by old PKZip 1.x are not supported
|
||||
|
||||
THIS IS AN ALPHA VERSION. AT THIS STAGE OF DEVELOPPEMENT, SOMES API OR STRUCTURE
|
||||
CAN CHANGE IN FUTURE VERSION !!
|
||||
I WAIT FEEDBACK at mail info@winimage.com

Frequently Asked Question:
|

|

Q: Each time I use the compress function I get the -5 error (not enough
|
||||
room in the output buffer).
|
||||
|
||||
A: Make sure that the length of the compressed buffer is passed by
|
||||
reference ("as any"), not by value ("as long"). Also check that
|
||||
before the call of compress this length is equal to the total size of
|
||||
the compressed buffer and not zero.

<a name="Introduction"><h2> Introduction </h2>
|
||||
The 'zlib' compression library provides in-memory compression and
|
||||
decompression functions, including integrity checks of the uncompressed
|
||||
data. This version of the library supports only one compression method
|
||||
(deflation) but other algorithms will be added later and will have the same
|
||||
stream interface.
|
||||
<p>
|
||||
|
||||
Compression can be done in a single step if the buffers are large
|
||||
enough (for example if an input file is mmap'ed), or can be done by
|
||||
repeated calls of the compression function. In the latter case, the
|
||||
application must provide more input and/or consume the output
|
||||
(providing more output space) before each call.
|
||||
<p>
|
||||
|
||||
The library also supports reading and writing files in gzip (.gz) format
|
||||
with an interface similar to that of stdio.
|
||||
<p>
|
||||
|
||||
The library does not install any signal handler. The decoder checks
|
||||
the consistency of the compressed data, so the library should never
|
||||
crash even in case of corrupted input.

||||

<a name="Utility functions"><h2> Utility functions </h2>
|
||||
The following utility functions are implemented on top of the
|
||||
<a href="#Basic functions">basic stream-oriented functions</a>.
|
||||
To simplify the interface, some
|
||||
default options are assumed (compression level and memory usage,
|
||||
standard memory allocation functions). The source code of these
|
||||
utility functions can easily be modified if you need special options.

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". (See the description

The mode parameter is as in <a href="#gzopen">gzopen</a>.

<font color="Blue"><dt> int <a name="gzflush">gzflush</a> (gzFile file, int flush);</font>
|

<dd>
|

Flushes all pending output into the compressed file. The parameter
|
||||
flush is as in the <a href="#deflate">deflate</a>() function. The return value is the zlib
|
||||
error number (see function <a href="#gzerror">gzerror</a> below). <a href="#gzflush">gzflush</a> returns <a href="#Z_OK">Z_OK</a> if
|

the flush parameter is <a href="#Z_FINISH">Z_FINISH</a> and all output could be flushed.
|

<p>
|

<dd>
|

Sets the starting position for the next <a href="#gzread">gzread</a> or <a href="#gzwrite">gzwrite</a> on the
|

given compressed file. The offset represents a number of bytes in the
|
||||
uncompressed data stream. The whence parameter is defined as in lseek(2);
|
||||
the value SEEK_END is not supported.
|
||||
<p>
|
||||
If the file is opened for reading, this function is emulated but can be
|
||||
extremely slow. If the file is opened for writing, only forward seeks are
|

supported ; <a href="#gzseek">gzseek</a> then compresses a sequence of zeroes up to the new
|
||||
starting position.
|
||||
<p>
|
||||
<a href="#gzseek">gzseek</a> returns the resulting offset location as measured in bytes from
|

particular if the file is opened for writing and the new starting position
|
||||
would be before the current position.

<dd>
|

Returns the starting position for the next <a href="#gzread">gzread</a> or <a href="#gzwrite">gzwrite</a> on the
|

given compressed file. This position represents a number of bytes in the
|
||||
uncompressed data stream.

<font color="Blue"><dt> int <a name="gzclose">gzclose</a> (gzFile file);</font>
|

<dd>
|

Flushes all pending output if necessary, closes the compressed file
|

and deallocates all the (de)compression <a href="#state">state</a>. The return value is the zlib
|

|
||||
<font color="Blue"><dt> const char * <a name="gzerror">gzerror</a> (gzFile file, int *errnum);</font>
|

<dd>
|

Returns the error message for the last error which occurred on the
|
||||
given compressed file. errnum is set to zlib error number. If an
|
||||
error occurred in the file system and not in the compression library,
|
||||
errnum is set to <a href="#Z_ERRNO">Z_ERRNO</a> and the application may consult errno
|
||||
to get the exact error code.

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

compression method from the zlib header and allocates all data structures

accordingly ; otherwise the allocation will be deferred to the first call of

|

<dd>
|

<a href="#inflate">inflate</a> 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.
|
||||
<p>
|
||||
|
||||
The detailed semantics are as follows. <a href="#inflate">inflate</a> performs one or both of the
|
||||
following actions:
|
||||
|
||||
<ul>
|
||||
<li> Decompress more input starting at <a href="#next_in">next_in</a> and update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a>
|
||||
accordingly. If not all input can be processed (because there is not
|
||||
enough room in the output buffer), <a href="#next_in">next_in</a> is updated and processing
|
||||
will resume at this point for the next call of <a href="#inflate">inflate</a>().
|
||||
|
||||
<li> Provide more output starting at <a href="#next_out">next_out</a> and update <a href="#next_out">next_out</a> and
|
||||
<a href="#avail_out">avail_out</a> accordingly. <a href="#inflate">inflate</a>() 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).
|
||||
</ul> <p>
|
||||
|
||||
Before the call of <a href="#inflate">inflate</a>(), the application should ensure that at least
|
||||
one of the actions is possible, by providing more input and/or consuming
|
||||
more output, and updating the next_* and avail_* values accordingly.
|
||||
The application can consume the uncompressed output when it wants, for
|
||||
example when the output buffer is full (<a href="#avail_out">avail_out</a> == 0), or after each
|
||||
call of <a href="#inflate">inflate</a>(). If <a href="#inflate">inflate</a> returns <a href="#Z_OK">Z_OK</a> and with zero <a href="#avail_out">avail_out</a>, it
|
||||
must be called again after making room in the output buffer because there
|
||||
might be more output pending.
|
||||
<p>
|
||||
|
||||
If the parameter flush is set to <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>, <a href="#inflate">inflate</a> flushes as much
|
||||
output as possible to the output buffer. The flushing behavior of <a href="#inflate">inflate</a> is
|
||||
not specified for values of the flush parameter other than <a href="#Z_SYNC_FLUSH">Z_SYNC_FLUSH</a>
|
||||
and <a href="#Z_FINISH">Z_FINISH</a>, but the current implementation actually flushes as much output
|
||||
as possible anyway.
|
||||
<p>
|
||||
|
||||
<a href="#inflate">inflate</a>() should normally be called until it returns <a href="#Z_STREAM_END">Z_STREAM_END</a> or an
|
||||
error. However if all decompression is to be performed in a single step
|
||||
(a single call of <a href="#inflate">inflate</a>), the parameter flush should be set to
|
||||
<a href="#Z_FINISH">Z_FINISH</a>. In this case all pending input is processed and all pending
|
||||
output is flushed ; <a href="#avail_out">avail_out</a> 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 <a href="#inflateEnd">inflateEnd</a> to deallocate the decompression <a href="#state">state</a>. The use of <a href="#Z_FINISH">Z_FINISH</a>
|
||||
is never required, but can be used to inform <a href="#inflate">inflate</a> that a faster routine
|
||||
may be used for the single <a href="#inflate">inflate</a>() call.
|
||||
<p>
|
||||
|
||||
If a preset dictionary is needed at this point (see <a href="#inflateSetDictionary">inflateSetDictionary</a>
|
||||
below), <a href="#inflate">inflate</a> sets strm-<a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of the
|
||||
dictionary chosen by the compressor and returns <a href="#Z_NEED_DICT">Z_NEED_DICT</a> ; otherwise
|
||||
it sets strm-> <a href="#adler">adler</a> to the <a href="#adler32">adler32</a> checksum of all output produced
|
||||
so far (that is, <a href="#total_out">total_out</a> bytes) and returns <a href="#Z_OK">Z_OK</a>, <a href="#Z_STREAM_END">Z_STREAM_END</a> or
|
||||
an error code as described below. At the end of the stream, <a href="#inflate">inflate</a>()
|
||||
checks that its computed <a href="#adler32">adler32</a> checksum is equal to that saved by the
|
||||
compressor and returns <a href="#Z_STREAM_END">Z_STREAM_END</a> only if the checksum is correct.
|
||||
<p>
|
||||
|
||||
<a href="#inflate">inflate</a>() returns <a href="#Z_OK">Z_OK</a> if some progress has been made (more input processed
|
||||
or more output produced), <a href="#Z_STREAM_END">Z_STREAM_END</a> if the end of the compressed data has
|
||||
been reached and all uncompressed output has been produced, <a href="#Z_NEED_DICT">Z_NEED_DICT</a> if a
|
||||
preset dictionary is needed at this point, <a href="#Z_DATA_ERROR">Z_DATA_ERROR</a> if the input data was
|

corrupted (input stream not conforming to the zlib format or incorrect
|
||||
<a href="#adler32">adler32</a> checksum), <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the stream structure was inconsistent
|

(for example if <a href="#next_in">next_in</a> or <a href="#next_out">next_out</a> was NULL), <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not

enough memory, <a href="#Z_BUF_ERROR">Z_BUF_ERROR</a> if no progress is possible or if there was not

enough room in the output buffer when <a href="#Z_FINISH">Z_FINISH</a> is used. In the <a href="#Z_DATA_ERROR">Z_DATA_ERROR</a>

case, the application may then call <a href="#inflateSync">inflateSync</a> to look for a good

compression block.

<dd> This is another version of <a href="#deflateInit">deflateInit</a> with more compression options. The
|
||||
fields <a href="#next_in">next_in</a>, <a href="#zalloc">zalloc</a>, <a href="#zfree">zfree</a> and <a href="#opaque">opaque</a> must be initialized before by
|
||||
the caller.<p>
|
||||
|
||||
The method parameter is the compression method. It must be <a href="#Z_DEFLATED">Z_DEFLATED</a> in
|
||||
this version of the library.<p>
|
||||
|
||||
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
|
||||
<a href="#deflateInit">deflateInit</a> is used instead.<p>
|
||||
|
||||
The memLevel parameter specifies how much memory should be allocated
|
||||
for the internal compression <a href="#state">state</a>. 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.<p>
|
||||
|
||||
The strategy parameter is used to tune the compression algorithm. Use the
|
||||
value <a href="#Z_DEFAULT_STRATEGY">Z_DEFAULT_STRATEGY</a> for normal data, <a href="#Z_FILTERED">Z_FILTERED</a> for data produced by a
|
||||
filter (or predictor), or <a href="#Z_HUFFMAN_ONLY">Z_HUFFMAN_ONLY</a> 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 <a href="#compress">compress</a> them better. The effect of <a href="#Z_FILTERED">Z_FILTERED</a> is to force more
|
||||
Huffman coding and less string matching ; it is somewhat intermediate
|
||||
between Z_DEFAULT and <a href="#Z_HUFFMAN_ONLY">Z_HUFFMAN_ONLY</a>. The strategy parameter only affects
|
||||
the compression ratio but not the correctness of the compressed output even
|
||||
if it is not set appropriately.<p>
|
||||
|
||||
<a href="#deflateInit2">deflateInit2</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not enough
|

memory, <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if a parameter is invalid (such as an invalid
|
||||
method). <a href="#msg">msg</a> is set to null if there is no error message. <a href="#deflateInit2">deflateInit2</a> does

not perform any compression: this will be done by <a href="#deflate">deflate</a>().<p>

<dd>
|

Initializes the compression dictionary from the given byte sequence
|
||||
without producing any compressed output. This function must be called
|
||||
immediately after <a href="#deflateInit">deflateInit</a>, <a href="#deflateInit2">deflateInit2</a> or <a href="#deflateReset">deflateReset</a>, before any
|
||||
call of <a href="#deflate">deflate</a>. The compressor and decompressor must use exactly the same
|
||||
dictionary (see <a href="#inflateSetDictionary">inflateSetDictionary</a>).<p>
|
||||
|
||||
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.<p>
|
||||
|
||||
Depending on the size of the compression data structures selected by
|
||||
<a href="#deflateInit">deflateInit</a> or <a href="#deflateInit2">deflateInit2</a>, a part of the dictionary may in effect be
|
||||
discarded, for example if the dictionary is larger than the window size in
|
||||
<a href="#deflate">deflate</a> or deflate2. Thus the strings most likely to be useful should be
|
||||
put at the end of the dictionary, not at the front.<p>
|
||||
|
||||
Upon return of this function, strm-> <a href="#adler">adler</a> 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.)<p>

<a href="#deflateSetDictionary">deflateSetDictionary</a> returns <a href="#Z_OK">Z_OK</a> if success, or <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if a

parameter is invalid (such as NULL dictionary) or the stream <a href="#state">state</a> is
|
||||
inconsistent (for example if <a href="#deflate">deflate</a> has already been called for this stream
|
||||
or if the compression method is bsort). <a href="#deflateSetDictionary">deflateSetDictionary</a> does not

Sets the destination stream as a complete copy of the source stream.<p>
|

|

This function can be useful when several compression strategies will be
|
||||
tried, for example when there are several ways of pre-processing the input
|
||||
data with a filter. The streams that will be discarded should then be freed
|
||||
by calling <a href="#deflateEnd">deflateEnd</a>. Note that <a href="#deflateCopy">deflateCopy</a> duplicates the internal
|

compression <a href="#state">state</a> which can be quite large, so this strategy is slow and

can consume lots of memory.<p>

<a href="#deflateCopy">deflateCopy</a> returns <a href="#Z_OK">Z_OK</a> if success, <a href="#Z_MEM_ERROR">Z_MEM_ERROR</a> if there was not

enough memory, <a href="#Z_STREAM_ERROR">Z_STREAM_ERROR</a> if the source stream <a href="#state">state</a> was inconsistent

<dd>
|

Dynamically update the compression level and compression strategy. The
|
||||
interpretation of level and strategy is as in <a href="#deflateInit2">deflateInit2</a>. This can 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 level is changed, the input available so far
|
||||
is compressed with the old level (and may be flushed); the new level will

take effect only at the next call of <a href="#deflate">deflate</a>().<p>
|

Before the call of <a href="#deflateParams">deflateParams</a>, the stream <a href="#state">state</a> must be set as for

a call of <a href="#deflate">deflate</a>(), since the currently available input may have to

be compressed and flushed. In particular, strm-> <a href="#avail_out">avail_out</a> must be

non-zero.<p>

These functions are not related to compression but are exported
|
||||
anyway because they might be useful in applications using the
|
||||
compression library.

<h3> Function list </h3>
|
||||
<ul>
|
||||
<li> uLong <a href="#adler32">adler32</a> (uLong <a href="#adler">adler</a>, const Bytef *buf, uInt len);
|
||||
<li> uLong <a href="#crc32">crc32</a> (uLong crc, const Bytef *buf, uInt len);
|
||||
</ul>
|
||||
<h3> Function description </h3>
|
||||
<dl>
|
||||
<font color="Blue"><dt> uLong <a name="adler32">adler32</a> (uLong <a href="#adler">adler</a>, const Bytef *buf, uInt len);</font>
|
||||
<dd>
|
||||
Update a running Adler-32 checksum with the bytes buf[0..len-1] and
|
||||
return the updated checksum. If buf is NULL, this function returns
|
||||
the required initial value for the checksum.
|
||||
<p>
|
||||
An Adler-32 checksum is almost as reliable as a CRC32 but can be computed
|
||||
much faster. Usage example:
|
||||
<pre>
|
||||
|
||||
uLong <a href="#adler">adler</a> = <a href="#adler32">adler32</a>(0L, <a href="#Z_NULL">Z_NULL</a>, 0);
|
||||
|
||||
while (read_buffer(buffer, length) != EOF) {
|
||||
<a href="#adler">adler</a> = <a href="#adler32">adler32</a>(<a href="#adler">adler</a>, buffer, length);
|
||||
}
|
||||
if (<a href="#adler">adler</a> != original_adler) error();
|
||||
</pre>
|
||||
|
||||
<font color="Blue"><dt> uLong <a name="crc32">crc32</a> (uLong crc, const Bytef *buf, uInt len);</font>
|
||||
<dd>
|
||||
Update a running crc with the bytes buf[0..len-1] and return the updated
|
||||
crc. If buf is NULL, this function returns the required initial value
|
||||
for the crc. Pre- and post-conditioning (one's complement) is performed
|
||||
within this function so it shouldn't be done by the application.
|
||||
Usage example:
|
||||
<pre>
|
||||
|
||||
uLong crc = <a href="#crc32">crc32</a>(0L, <a href="#Z_NULL">Z_NULL</a>, 0);
|
||||
|
||||
while (read_buffer(buffer, length) != EOF) {
|
||||
crc = <a href="#crc32">crc32</a>(crc, buffer, length);
|
||||
}
|
||||
if (crc != original_crc) error();

The application must update <a href="#next_in">next_in</a> and <a href="#avail_in">avail_in</a> when <a href="#avail_in">avail_in</a> has

|

has dropped to zero. The application must initialize <a href="#zalloc">zalloc</a>, <a href="#zfree">zfree</a> and

<a href="#opaque">opaque</a> before calling the init function. All other fields are set by the
|

compression library and must not be updated by the application. <p>
|
||||
|
||||
The <a href="#opaque">opaque</a> value provided by the application will be passed as the first
|
||||
parameter for calls of <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a>. This can be useful for custom
|
||||
memory management. The compression library attaches no meaning to the
|
||||
<a href="#opaque">opaque</a> value. <p>
|
||||
|
||||
<a href="#zalloc">zalloc</a> must return <a href="#Z_NULL">Z_NULL</a> if there is not enough memory for the object.
|
||||
If zlib is used in a multi-threaded application, <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a> must be
|
||||
thread safe. <p>
|
||||
|
||||
On 16-bit systems, the functions <a href="#zalloc">zalloc</a> and <a href="#zfree">zfree</a> 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 <a href="#zalloc">zalloc</a> 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).
|
||||
<p>
|
||||
|
||||
The fields <a href="#total_in">total_in</a> and <a href="#total_out">total_out</a> can be used for statistics or
|
||||
progress reports. After compression, <a href="#total_in">total_in</a> holds the total size of
|
||||
the uncompressed data and may be saved for use in the decompressor
|
||||
(particularly if the decompressor wants to decompress everything in
|
||||
a single step). <p>
