README file for PCRE (Perl-compatible regular expression library)
|
||||
-----------------------------------------------------------------
|
||||
|
||||
The latest release of PCRE is always available from
|
||||
|
||||
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-xxx.tar.gz
|
||||
|
||||
Please read the NEWS file if you are upgrading from a previous release.
|
||||
|
||||
PCRE has its own native API, but a set of "wrapper" functions that are based on
|
||||
the POSIX API are also supplied in the library libpcreposix. Note that this
|
||||
just provides a POSIX calling interface to PCRE: the regular expressions
|
||||
themselves still follow Perl syntax and semantics. The header file
|
||||
for the POSIX-style functions is called pcreposix.h. The official POSIX name is
|
||||
regex.h, but I didn't want to risk possible problems with existing files of
|
||||
that name by distributing it that way. To use it with an existing program that
|
||||
uses the POSIX API, it will have to be renamed or pointed at by a link.
|
||||
|
||||
If you are using the POSIX interface to PCRE and there is already a POSIX regex
|
||||
library installed on your system, you must take care when linking programs to
|
||||
ensure that they link with PCRE's libpcreposix library. Otherwise they may pick
|
||||
up the "real" POSIX functions of the same name.
|
||||
|
||||
|
||||
Contributions by users of PCRE
|
||||
------------------------------
|
||||
|
||||
You can find contributions from PCRE users in the directory
|
||||
|
||||
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib
|
||||
|
||||
where there is also a README file giving brief descriptions of what they are.
|
||||
Several of them provide support for compiling PCRE on various flavours of
|
||||
Windows systems (I myself do not use Windows). Some are complete in themselves;
|
||||
others are pointers to URLs containing relevant files.
|
||||
|
||||
|
||||
Building PCRE on a Unix-like system
|
||||
-----------------------------------
|
||||
|
||||
To build PCRE on a Unix-like system, first run the "configure" command from the
|
||||
PCRE distribution directory, with your current directory set to the directory
|
||||
where you want the files to be created. This command is a standard GNU
|
||||
"autoconf" configuration script, for which generic instructions are supplied in
|
||||
INSTALL.
|
||||
|
||||
Most commonly, people build PCRE within its own distribution directory, and in
|
||||
this case, on many systems, just running "./configure" is sufficient, but the
|
||||
usual methods of changing standard defaults are available. For example,
|
||||
|
||||
CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
|
||||
|
||||
specifies that the C compiler should be run with the flags '-O2 -Wall' instead
|
||||
of the default, and that "make install" should install PCRE under /opt/local
|
||||
instead of the default /usr/local.
|
||||
|
||||
If you want to build in a different directory, just run "configure" with that
|
||||
directory as current. For example, suppose you have unpacked the PCRE source
|
||||
into /source/pcre/pcre-xxx, but you want to build it in /build/pcre/pcre-xxx:
|
||||
|
||||
cd /build/pcre/pcre-xxx
|
||||
/source/pcre/pcre-xxx/configure
|
||||
|
||||
There are some optional features that can be included or omitted from the PCRE
|
||||
library. You can read more about them in the pcrebuild man page.
|
||||
|
||||
. If you want to make use of the support for UTF-8 character strings in PCRE,
|
||||
you must add --enable-utf8 to the "configure" command. Without it, the code
|
||||
for handling UTF-8 is not included in the library. (Even when included, it
|
||||
still has to be enabled by an option at run time.)
|
||||
|
||||
. You can build PCRE to recognized CR or NL as the newline character, instead
|
||||
of whatever your compiler uses for "\n", by adding --newline-is-cr or
|
||||
--newline-is-nl to the "configure" command, respectively. Only do this if you
|
||||
really understand what you are doing. On traditional Unix-like systems, the
|
||||
newline character is NL.
|
||||
|
||||
. When called via the POSIX interface, PCRE uses malloc() to get additional
|
||||
storage for processing capturing parentheses if there are more than 10 of
|
||||
them. You can increase this threshold by setting, for example,
|
||||
|
||||
--with-posix-malloc-threshold=20
|
||||
|
||||
on the "configure" command.
|
||||
|
||||
. PCRE has a counter which can be set to limit the amount of resources it uses.
|
||||
If the limit is exceeded during a match, the match fails. The default is ten
|
||||
million. You can change the default by setting, for example,
|
||||
|
||||
--with-match-limit=500000
|
||||
|
||||
on the "configure" command. This is just the default; individual calls to
|
||||
pcre_exec() can supply their own value. There is discussion on the pcreapi
|
||||
man page.
|
||||
|
||||
. The default maximum compiled pattern size is around 64K. You can increase
|
||||
this by adding --with-link-size=3 to the "configure" command. You can
|
||||
increase it even more by setting --with-link-size=4, but this is unlikely
|
||||
ever to be necessary. If you build PCRE with an increased link size, test 2
|
||||
(and 5 if you are using UTF-8) will fail. Part of the output of these tests
|
||||
is a representation of the compiled pattern, and this changes with the link
|
||||
size.
|
||||
|
||||
. You can build PCRE so that its match() function does not call itself
|
||||
recursively. Instead, it uses blocks of data from the heap via special
|
||||
functions pcre_stack_malloc() and pcre_stack_free() to save data that would
|
||||
otherwise be saved on the stack. To build PCRE like this, use
|
||||
|
||||
--disable-stack-for-recursion
|
||||
|
||||
on the "configure" command. PCRE runs more slowly in this mode, but it may be
|
||||
necessary in environments with limited stack sizes.
|
||||
|
||||
The "configure" script builds five files:
|
||||
|
||||
. libtool is a script that builds shared and/or static libraries
|
||||
. Makefile is built by copying Makefile.in and making substitutions.
|
||||
. config.h is built by copying config.in and making substitutions.
|
||||
. pcre-config is built by copying pcre-config.in and making substitutions.
|
||||
. RunTest is a script for running tests
|
||||
|
||||
Once "configure" has run, you can run "make". It builds two libraries called
|
||||
libpcre and libpcreposix, a test program called pcretest, and the pcregrep
|
||||
command. You can use "make install" to copy these, the public header files
|
||||
pcre.h and pcreposix.h, and the man pages to appropriate live directories on
|
||||
your system, in the normal way.
|
||||
|
||||
Running "make install" also installs the command pcre-config, which can be used
|
||||
to recall information about the PCRE configuration and installation. For
|
||||
example,
|
||||
|
||||
pcre-config --version
|
||||
|
||||
prints the version number, and
|
||||
|
||||
pcre-config --libs
|
||||
|
||||
outputs information about where the library is installed. This command can be
|
||||
included in makefiles for programs that use PCRE, saving the programmer from
|
||||
having to remember too many details.
|
||||
|
||||
|
||||
Shared libraries on Unix-like systems
|
||||
-------------------------------------
|
||||
|
||||
The default distribution builds PCRE as two shared libraries and two static
|
||||
libraries, as long as the operating system supports shared libraries. Shared
|
||||
library support relies on the "libtool" script which is built as part of the
|
||||
"configure" process.
|
||||
|
||||
The libtool script is used to compile and link both shared and static
|
||||
libraries. They are placed in a subdirectory called .libs when they are newly
|
||||
built. The programs pcretest and pcregrep are built to use these uninstalled
|
||||
libraries (by means of wrapper scripts in the case of shared libraries). When
|
||||
you use "make install" to install shared libraries, pcregrep and pcretest are
|
||||
automatically re-built to use the newly installed shared libraries before being
|
||||
installed themselves. However, the versions left in the source directory still
|
||||
use the uninstalled libraries.
|
||||
|
||||
To build PCRE using static libraries only you must use --disable-shared when
|
||||
configuring it. For example
|
||||
|
||||
./configure --prefix=/usr/gnu --disable-shared
|
||||
|
||||
Then run "make" in the usual way. Similarly, you can use --disable-static to
|
||||
build only shared libraries.
|
||||
|
||||
|
||||
Cross-compiling on a Unix-like system
|
||||
-------------------------------------
|
||||
|
||||
You can specify CC and CFLAGS in the normal way to the "configure" command, in
|
||||
order to cross-compile PCRE for some other host. However, during the building
|
||||
process, the dftables.c source file is compiled *and run* on the local host, in
|
||||
order to generate the default character tables (the chartables.c file). It
|
||||
therefore needs to be compiled with the local compiler, not the cross compiler.
|
||||
You can do this by specifying CC_FOR_BUILD (and if necessary CFLAGS_FOR_BUILD)
|
||||
when calling the "configure" command. If they are not specified, they default
|
||||
to the values of CC and CFLAGS.
|
||||
|
||||
|
||||
Building on non-Unix systems
|
||||
----------------------------
|
||||
|
||||
For a non-Unix system, read the comments in the file NON-UNIX-USE, though if
|
||||
the system supports the use of "configure" and "make" you may be able to build
|
||||
PCRE in the same way as for Unix systems.
|
||||
|
||||
PCRE has been compiled on Windows systems and on Macintoshes, but I don't know
|
||||
the details because I don't use those systems. It should be straightforward to
|
||||
build PCRE on any system that has a Standard C compiler, because it uses only
|
||||
Standard C functions.
|
||||
|
||||
|
||||
Testing PCRE
|
||||
------------
|
||||
|
||||
To test PCRE on a Unix system, run the RunTest script that is created by the
|
||||
configuring process. (This can also be run by "make runtest", "make check", or
|
||||
"make test".) For other systems, see the instructions in NON-UNIX-USE.
|
||||
|
||||
The script runs the pcretest test program (which is documented in its own man
|
||||
page) on each of the testinput files (in the testdata directory) in turn,
|
||||
and compares the output with the contents of the corresponding testoutput file.
|
||||
A file called testtry is used to hold the output from pcretest. To run pcretest
|
||||
on just one of the test files, give its number as an argument to RunTest, for
|
||||
example:
|
||||
|
||||
RunTest 2
|
||||
|
||||
The first file can also be fed directly into the perltest script to check that
|
||||
Perl gives the same results. The only difference you should see is in the first
|
||||
few lines, where the Perl version is given instead of the PCRE version.
|
||||
|
||||
The second set of tests check pcre_fullinfo(), pcre_info(), pcre_study(),
|
||||
pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error
|
||||
detection, and run-time flags that are specific to PCRE, as well as the POSIX
|
||||
wrapper API. It also uses the debugging flag to check some of the internals of
|
||||
pcre_compile().
|
||||
|
||||
If you build PCRE with a locale setting that is not the standard C locale, the
|
||||
character tables may be different (see next paragraph). In some cases, this may
|
||||
cause failures in the second set of tests. For example, in a locale where the
|
||||
isprint() function yields TRUE for characters in the range 128-255, the use of
|
||||
[:isascii:] inside a character class defines a different set of characters, and
|
||||
this shows up in this test as a difference in the compiled code, which is being
|
||||
listed for checking. Where the comparison test output contains [\x00-\x7f] the
|
||||
test will contain [\x00-\xff], and similarly in some other cases. This is not a
|
||||
bug in PCRE.
|
||||
|
||||
The third set of tests checks pcre_maketables(), the facility for building a
|
||||
set of character tables for a specific locale and using them instead of the
|
||||
default tables. The tests make use of the "fr_FR" (French) locale. Before
|
||||
running the test, the script checks for the presence of this locale by running
|
||||
the "locale" command. If that command fails, or if it doesn't include "fr_FR"
|
||||
in the list of available locales, the third test cannot be run, and a comment
|
||||
is output to say why. If running this test produces instances of the error
|
||||
|
||||
** Failed to set locale "fr_FR"
|
||||
|
||||
in the comparison output, it means that locale is not available on your system,
|
||||
despite being listed by "locale". This does not mean that PCRE is broken.
|
||||
|
||||
The fourth test checks the UTF-8 support. It is not run automatically unless
|
||||
PCRE is built with UTF-8 support. To do this you must set --enable-utf8 when
|
||||
running "configure". This file can be also fed directly to the perltest script,
|
||||
provided you are running Perl 5.8 or higher. (For Perl 5.6, a small patch,
|
||||
commented in the script, can be be used.)
|
||||
|
||||
The fifth and final file tests error handling with UTF-8 encoding, and internal
|
||||
UTF-8 features of PCRE that are not relevant to Perl.
|
||||
|
||||
|
||||
Character tables
|
||||
----------------
|
||||
|
||||
PCRE uses four tables for manipulating and identifying characters. The final
|
||||
argument of the pcre_compile() function is a pointer to a block of memory
|
||||
containing the concatenated tables. A call to pcre_maketables() can be used to
|
||||
generate a set of tables in the current locale. If the final argument for
|
||||
pcre_compile() is passed as NULL, a set of default tables that is built into
|
||||
the binary is used.
|
||||
|
||||
The source file called chartables.c contains the default set of tables. This is
|
||||
not supplied in the distribution, but is built by the program dftables
|
||||
(compiled from dftables.c), which uses the ANSI C character handling functions
|
||||
such as isalnum(), isalpha(), isupper(), islower(), etc. to build the table
|
||||
sources. This means that the default C locale which is set for your system will
|
||||
control the contents of these default tables. You can change the default tables
|
||||
by editing chartables.c and then re-building PCRE. If you do this, you should
|
||||
probably also edit Makefile to ensure that the file doesn't ever get
|
||||
re-generated.
|
||||
|
||||
The first two 256-byte tables provide lower casing and case flipping functions,
|
||||
respectively. The next table consists of three 32-byte bit maps which identify
|
||||
digits, "word" characters, and white space, respectively. These are used when
|
||||
building 32-byte bit maps that represent character classes.
|
||||
|
||||
The final 256-byte table has bits indicating various character types, as
|
||||
follows:
|
||||
|
||||
1 white space character
|
||||
2 letter
|
||||
4 decimal digit
|
||||
8 hexadecimal digit
|
||||
16 alphanumeric or '_'
|
||||
128 regular expression metacharacter or binary zero
|
||||
|
||||
You should not alter the set of characters that contain the 128 bit, as that
|
||||
will cause PCRE to malfunction.
|
||||

compiled regex to around 64K, which is big enough for almost everybody.

also to make the code easier to maintain, the storing and loading of offsets

from the byte string is now handled by the macros that are defined here.

the config.h file, but can be overridden by using -D on the command line. This

is automated on Unix systems via the "configure" command. */

Changes in 1.2.3.3 (2 October 2006)
|
||||
- Make --shared the default for configure, add a --static option
|
||||
- Add compile option to permit invalid distance-too-far streams
|
||||
- Add inflateUndermine() function which is required to enable above
|
||||
- Remove use of "this" variable name for C++ compatibility [Marquess]
|
||||
- Add testing of shared library in make test, if shared library built
|
||||
- Use ftello() and fseeko() if available instead of ftell() and fseek()
|
||||
- Provide two versions of all functions that use the z_off_t type for
|
||||
binary compatibility -- a normal version and a 64-bit offset version,

Changes in 1.0.3 (2 Jul 96)
|
||||
- use z_streamp instead of z_stream *, which is now a far pointer in MSDOS
|
||||
small and medium models; this makes the library incompatible with previous
|
||||
versions for these models. (No effect in large model or on other systems.)
|
||||
- return OK instead of BUF_ERROR if previous deflate call returned with
|
||||
avail_out as zero but there is nothing to do
|
||||
- added memcmp for non STDC compilers
|
||||
- define NO_DUMMY_DECL for more Mac compilers (.h files merged incorrectly)
|
||||
- define __32BIT__ if __386__ or i386 is defined (pb. with Watcom and SCO)
|
||||
- better check for 16-bit mode MSC (avoids problem with Symantec)
|
||||
|
||||
Changes in 1.0.2 (23 May 96)
|
||||
- added Windows DLL support
|
||||
- added a function zlibVersion (for the DLL support)
|
||||
- fixed declarations using Bytef in infutil.c (pb with MSDOS medium model)
|
||||
- Bytef is define's instead of typedef'd only for Borland C
|
||||
- avoid reading uninitialized memory in example.c
|
||||
- mention in README that the zlib format is now RFC1950
|
||||
- updated Makefile.dj2
|
||||
- added algorithm.doc
|
||||
|
||||

|
||||
- allow preset dictionary shared between compressor and decompressor
|
||||
- allow compression level 0 (no compression)
|

- add deflateParams in zlib.h: allow dynamic change of compression level
|
||||
and compression strategy.
|
||||
- test large buffers and deflateParams in example.c
|

- default window size is same for compression and decompression
|
||||
(it's now sufficient to set MAX_WBITS in zconf.h).
|
||||
- voidp -> voidpf and voidnp -> voidp (for consistency with other
|
||||
typedefs and because voidnp was not near in large model).
|

|
||||
- added support for DJGPP
|
||||
|
||||
Changes in 0.9 (1 May 95)
|
||||
- don't assume that zalloc clears the allocated memory (the TurboC bug
|
||||
was Mark's bug after all :)
|
||||
- let again gzread copy uncompressed data unchanged (was working in 0.71)
|
||||
- deflate(Z_FULL_FLUSH), inflateReset and inflateSync are now fully implemented
|
||||
- added a test of inflateSync in example.c
|

||||
Changes in 0.8 (29 April 95)
|
||||
- added fast inflate (inffast.c)
|

- deflate(Z_FINISH) now returns Z_STREAM_END when done. Warning: this
|
||||
is incompatible with previous versions of zlib which returned Z_OK.
|
||||
- work around a TurboC compiler bug (bad code for b << 0, see infutil.h)
|
||||
(actually that was not a compiler bug, see 0.81 above)
|
||||
- gzread no longer reads one extra byte in certain cases
|
||||
- In gzio destroy(), don't reference a freed structure
|
||||

TurboC large model.
|
||||
|
||||
Changes in 0.7 (14 April 95)
|
||||
- Added full inflate support.
|
||||
- Simplified the crc32() interface. The pre- and post-conditioning
|
||||
(one's complement) is now done inside crc32(). WARNING: this is
|
||||
incompatible with previous versions; see zlib.h for the new usage.
|
||||
|
||||
Changes in 0.61 (12 April 95)
|
||||

|
||||
- fix some MSDOS compilation problems
|
||||
|
||||
Changes in 0.5:

|
||||
not yet Z_FULL_FLUSH.
|
||||
- support decompression but only in a single step (forced Z_FINISH)
|
||||
- added opaque object for zalloc and zfree.
|
||||
- added deflateReset and inflateReset
|
||||
- added a variable zlib_version for consistency checking.

|
||||
|
||||
Changes in 0.4:
|
||||
- avoid "zip" everywhere, use zlib instead of ziplib.
|
||||
- suppress Z_BLOCK_FLUSH, interpret Z_PARTIAL_FLUSH as block flush
|
||||
if compression method == 8.
|
||||
- added adler32 and crc32
|
||||
- renamed deflateOptions as deflateInit2, call one or the other but not both
|
||||
- added the method parameter for deflateInit2.
|
||||

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.
|
||||
See the file win32/DLL_FAQ.txt in the zlib distribution.
|
||||
Pointers to the precompiled DLL are found in the zlib web site at
|
||||
http://www.zlib.org.
|
||||
|
||||
3. Where can I get a Visual Basic interface to zlib?
|
||||
|
||||
See
|
||||
* http://www.dogma.net/markn/articles/zlibtool/zlibtool.htm
|
||||
* contrib/visual-basic.txt in the zlib distribution
|
||||
* win32/DLL_FAQ.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.
|
||||
Note that a Z_BUF_ERROR is not fatal--another call to deflate() or
|
||||
inflate() can be made with more input or output space. A Z_BUF_ERROR
|
||||
may in fact be unavoidable depending on how the functions are used, since
|
||||
it is not possible to tell whether or not there is more output pending
|
||||
when strm.avail_out returns with zero.
|
||||
|
||||
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 us (zlib@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 contrib/delphi directory in the zlib distribution.
|
||||
|
||||
11. Can zlib handle .zip archives?
|
||||
|
||||
Not by itself, no. 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. How do I install a shared zlib library on Unix?
|
||||
|
||||
After the above, then:
|
||||
|
||||
make install
|
||||
|
||||
However, many flavors of Unix come with a shared zlib already installed.
|
||||
Before going to the trouble of compiling a shared version of zlib and
|
||||
trying to install it, you may want to check if it's already there! If you
|
||||
can #include <zlib.h>, it's there. The -lz option will probably link to it.
|
||||
|
||||
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.
|
||||
|
||||
16. Can zlib decode Flate data in an Adobe PDF file?
|
||||
|
||||
Yes. See http://www.fastio.com/ (ClibPDF), or http://www.pdflib.com/ .
|
||||
To modify PDF forms, see http://sourceforge.net/projects/acroformtool/ .
|
||||
|
||||
17. Why am I getting this "register_frame_info not found" error on Solaris?
|
||||
|
||||
After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib
|
||||
generates an error such as:
|
||||
|
||||
ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so:
|
||||
symbol __register_frame_info: referenced symbol not found
|
||||
|
||||
The symbol __register_frame_info is not part of zlib, it is generated by
|
||||
the C compiler (cc or gcc). You must recompile applications using zlib
|
||||
which have this problem. This problem is specific to Solaris. See
|
||||
http://www.sunfreeware.com for Solaris versions of zlib and applications
|
||||
using zlib.
|
||||
|
||||
18. Why does gzip give an error on a file I make with compress/deflate?
|
||||
|
||||
The compress and deflate functions produce data in the zlib format, which
|
||||
is different and incompatible with the gzip format. The gz* functions in
|
||||
zlib on the other hand use the gzip format. Both the zlib and gzip
|
||||
formats use the same compressed data format internally, but have different
|
||||
headers and trailers around the compressed data.
|
||||
|
||||
19. Ok, so why are there two different formats?
|
||||
|
||||
The gzip format was designed to retain the directory information about
|
||||
a single file, such as the name and last modification date. The zlib
|
||||
format on the other hand was designed for in-memory and communication
|
||||
channel applications, and has a much more compact header and trailer and
|
||||
uses a faster integrity check than gzip.
|
||||
|
||||
20. Well that's nice, but how do I make a gzip file in memory?
|
||||
|
||||
You can request that deflate write the gzip format instead of the zlib
|
||||
format using deflateInit2(). You can also request that inflate decode
|
||||
the gzip format using inflateInit2(). Read zlib.h for more details.
|
||||
|
||||
21. Is zlib thread-safe?
|
||||
|
||||
Yes. However any library routines that zlib uses and any application-
|
||||
provided memory allocation routines must also be thread-safe. zlib's gz*
|
||||
functions use stdio library routines, and most of zlib's functions use the
|
||||
library memory allocation routines by default. zlib's Init functions allow
|
||||
for the application to provide custom memory allocation routines.
|
||||
|
||||
Of course, you should only operate on any given zlib or gzip stream from a
|
||||
single thread at a time.
|
||||
|
||||
22. Can I use zlib in my commercial application?
|
||||
|
||||
Yes. Please read the license in zlib.h.
|
||||
|
||||
23. Is zlib under the GNU license?
|
||||
|
||||
No. Please read the license in zlib.h.
|
||||
|
||||
24. The license says that altered source versions must be "plainly marked". So
|
||||
what exactly do I need to do to meet that requirement?
|
||||
|
||||
You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
|
||||
particular, the final version number needs to be changed to "f", and an
|
||||
identification string should be appended to ZLIB_VERSION. Version numbers
|
||||
x.x.x.f are reserved for modifications to zlib by others than the zlib
|
||||
maintainers. For example, if the version of the base zlib you are altering
|
||||
is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
|
||||
ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also
|
||||
update the version strings in deflate.c and inftrees.c.
|
||||
|
||||
For altered source distributions, you should also note the origin and
|
||||
nature of the changes in zlib.h, as well as in ChangeLog and README, along
|
||||
with the dates of the alterations. The origin should include at least your
|
||||
name (or your company's name), and an email address to contact for help or
|
||||
issues with the library.
|
||||
|
||||
Note that distributing a compiled zlib library along with zlib.h and
|
||||
zconf.h is also a source distribution, and so you should change
|
||||
ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes
|
||||
in zlib.h as you would for a full source distribution.
|
||||
|
||||
25. Will zlib work on a big-endian or little-endian architecture, and can I
|
||||
exchange compressed data between them?
|
||||
|
||||
Yes and yes.
|
||||
|
||||
26. Will zlib work on a 64-bit machine?
|
||||
|
||||
It should. It has been tested on 64-bit machines, and has no dependence
|
||||
on any data types being limited to 32-bits in length. If you have any
|
||||
difficulties, please provide a complete problem report to zlib@gzip.org
|
||||
|
||||
27. Will zlib decompress data from the PKWare Data Compression Library?
|
||||
|
||||
No. The PKWare DCL uses a completely different compressed data format
|
||||
than does PKZIP and zlib. However, you can look in zlib's contrib/blast
|
||||
directory for a possible solution to your problem.
|
||||
|
||||
28. Can I access data randomly in a compressed stream?
|
||||
|
||||
No, not without some preparation. If when compressing you periodically
|
||||
use Z_FULL_FLUSH, carefully write all the pending data at those points,
|
||||
and keep an index of those locations, then you can start decompression
|
||||
at those points. You have to be careful to not use Z_FULL_FLUSH too
|
||||
often, since it can significantly degrade compression.
|
||||
|
||||
29. Does zlib work on MVS, OS/390, CICS, etc.?
|
||||
|
||||
Yes, there are working ports of zlib 1.1.4 to MVS which you can find
|
||||
here:
|
||||
|
||||
http://www.homerow.net/asm/zlib390.htm
|
||||
http://www.homerow.net/asm/zlibLE.htm
|
||||
|
||||
If these are updated to more recent versions of zlib, please let us
|
||||
know. Thanks.
|
||||
|
||||
30. Is there some simpler, easier to read version of inflate I can look at
|
||||
to understand the deflate format?
|
||||
|
||||
First off, you should read RFC 1951. Second, yes. Look in zlib's
|
||||
contrib/puff directory.
|
||||
|
||||
31. Does zlib infringe on any patents?
|
||||
|
||||
As far as we know, no. In fact, that was originally the whole point behind
|
||||
zlib. Look here for some more information:
|
||||
|
||||
http://www.gzip.org/#faq11
|
||||
|
||||
32. Can zlib work with greater than 4 GB of data?
|
||||
|
||||
Yes. inflate() and deflate() will process any amount of data correctly.
|
||||
Each call of inflate() or deflate() is limited to input and output chunks
|
||||
of the maximum value that can be stored in the compiler's "unsigned int"
|
||||
type, but there is no limit to the number of chunks. Note however that the
|
||||
strm.total_in and strm_total_out counters may be limited to 4 GB. These
|
||||
counters are provided as a convenience and are not used internally by
|
||||
inflate() or deflate(). The application can easily set up its own counters
|
||||
updated after each call of inflate() or deflate() to count beyond 4 GB.
|
||||
compress() and uncompress() may be limited to 4 GB, since they operate in a
|
||||
single call. gzseek() and gztell() may be limited to 4 GB depending on how
|
||||
zlib is compiled. See the zlibCompileFlags() function in zlib.h.
|
||||
|
||||
The word "may" appears several times above since there is a 4 GB limit
|
||||
only if the compiler's "long" type is 32 bits. If the compiler's "long"
|
||||
type is 64 bits, then the limit is 16 exabytes.
|
||||
|
||||
33. Does zlib have any security vulnerabilities?
|
||||
|
||||
The only one that we are aware of is potentially in gzprintf(). If zlib
|
||||
is compiled to use sprintf() or vsprintf(), then there is no protection
|
||||
against a buffer overflow of a 4K string space, other than the caller of
|
||||
gzprintf() assuring that the output will not exceed 4K. On the other
|
||||
hand, if zlib is compiled to use snprintf() or vsnprintf(), which should
|
||||
normally be the case, then there is no vulnerability. The ./configure
|
||||
script will display warnings if an insecure variation of sprintf() will
|
||||
be used by gzprintf(). Also the zlibCompileFlags() function will return
|
||||
information on what variant of sprintf() is used by gzprintf().
|
||||
|
||||
If you don't have snprintf() or vsnprintf() and would like one, you can
|
||||
find a portable implementation here:
|
||||
|
||||
http://www.ijs.si/software/snprintf/
|
||||
|
||||
Note that you should be using the most recent version of zlib. Versions
|
||||
1.1.3 and before were subject to a double-free vulnerability, and version
|
||||
1.2.1 was subject to an access exception when decompressing invalid
|
||||
compressed data.
|
||||
|
||||
34. Is there a Java version of zlib?
|
||||
|
||||
Probably what you want is to use zlib in Java. zlib is already included
|
||||
as part of the Java SDK in the java.util.zip package. If you really want
|
||||
a version of zlib written in the Java language, look on the zlib home
|
||||
page for links: http://www.zlib.org/
|
||||
|
||||
35. I get this or that compiler or source-code scanner warning when I crank it
|
||||
up to maximally-pedantic. Can't you guys write proper code?
|
||||
|
||||
Many years ago, we gave up attempting to avoid warnings on every compiler
|
||||
in the universe. It just got to be a waste of time, and some compilers
|
||||
were downright silly. So now, we simply make sure that the code always
|
||||
works.
|
||||
|
||||
36. Valgrind (or some similar memory access checker) says that deflate is
|
||||
performing a conditional jump that depends on an uninitialized value.
|
||||
Isn't that a bug?
|
||||
|
||||
No. That is intentional for performance reasons, and the output of
|
||||
deflate is not affected. This only started showing up recently since
|
||||
zlib 1.2.x uses malloc() by default for allocations, whereas earlier
|
||||
versions used calloc(), which zeros out the allocated memory.
|
||||
|
||||
37. Will zlib read the (insert any ancient or arcane format here) compressed
|
||||
data format?
|
||||
|
||||
Probably not. Look in the comp.compression FAQ for pointers to various
|
||||
formats and associated software.
|
||||
|
||||
38. How can I encrypt/decrypt zip files with zlib?
|
||||
|
||||
zlib doesn't support encryption. The original PKZIP encryption is very weak
|
||||
and can be broken with freely available programs. To get strong encryption,
|
||||
use GnuPG, http://www.gnupg.org/ , which already includes zlib compression.
|
||||
For PKZIP compatible "encryption", look at http://www.info-zip.org/
|
||||
|
||||
39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings?
|
||||
|
||||
"gzip" is the gzip format, and "deflate" is the zlib format. They should
|
||||
probably have called the second one "zlib" instead to avoid confusion
|
||||
with the raw deflate compressed data format. While the HTTP 1.1 RFC 2616
|
||||
correctly points to the zlib specification in RFC 1950 for the "deflate"
|
||||
transfer encoding, there have been reports of servers and browsers that
|
||||
incorrectly produce or expect raw deflate data per the deflate
|
||||
specficiation in RFC 1951, most notably Microsoft. So even though the
|
||||
"deflate" transfer encoding using the zlib format would be the more
|
||||
efficient approach (and in fact exactly what the zlib format was designed
|
||||
for), using the "gzip" transfer encoding is probably more reliable due to
|
||||
an unfortunate choice of name on the part of the HTTP 1.1 authors.
|
||||
|
||||
Bottom line: use the gzip format for HTTP 1.1 encoding.
|
||||
|
||||
40. Does zlib support the new "Deflate64" format introduced by PKWare?
|
||||
|
||||
No. PKWare has apparently decided to keep that format proprietary, since
|
||||
they have not documented it as they have previous compression formats.
|
||||
In any case, the compression improvements are so modest compared to other
|
||||
more modern approaches, that it's not worth the effort to implement.
|
||||
|
||||
41. I'm having a problem with the zip functions in zlib, can you help?
|
||||
|
||||
There are no zip functions in zlib. You are probably using minizip by
|
||||
Giles Vollant, which is found in the contrib directory of zlib. It is not
|
||||
part of zlib. In fact none of the stuff in contrib is part of zlib. The
|
||||
files in there are not supported by the zlib authors. You need to contact
|
||||
the authors of the contribution for help.
|
||||
|
||||
42. The match.asm code in contrib is under the GNU General Public License.
|
||||
Since it's part of zlib, doesn't that mean that all of zlib falls under the
|
||||
GNU GPL?
|
||||
|
||||
No. The files in contrib are not part of zlib. They were contributed by
|
||||
other authors and are provided as a convenience to the user within the zlib
|
||||
distribution. Each of the items in contrib have their own license.
|
||||
|
||||
43. Can you please sign these lengthy legal documents and fax them back to us
|
||||
so that we can use your software in our product?
|
||||
|
||||
No. Go away. Shoo.

ZLIB DATA COMPRESSION LIBRARY
|
||||
|
||||
zlib 1.2.3.3 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
|
||||
http://www.ietf.org/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 zlib@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.
|
||||
|
||||
Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
|
||||
<info@winimage.com> for the Windows DLL version. The zlib home page is
|
||||
http://www.zlib.org or http://www.gzip.org/zlib/ 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://www.gzip.org/zlib/zlib_faq.html before asking
|
||||
for help.
|
||||
|
||||
Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
|
||||
issue of Dr. Dobb's Journal; a copy of the article is available in
|
||||
http://dogma.net/markn/articles/zlibtool/zlibtool.htm
|
||||
|
||||
The changes made in version 1.2.3.3 are documented in the file ChangeLog.
|
||||
|
||||
Unsupported third party contributions are provided in directory "contrib".
|
||||
|
||||
A Java implementation of zlib is available in the Java Development Kit
|
||||
http://java.sun.com/j2se/1.4.2/docs/api/java/util/zip/package-summary.html
|
||||
See the zlib home page http://www.zlib.org for details.

A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is in the
|
||||
CPAN (Comprehensive Perl Archive Network) sites
|
||||
http://www.cpan.org/modules/by-module/Compress/
|
||||
|

A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
|
||||
available in Python 1.5 and later versions, see
|

An experimental package to read and write files in .zip format, written on top
|
||||
of zlib by Gilles Vollant <info@winimage.com>, is available in the
|
||||
contrib/minizip directory of zlib.
|
||||
|
||||
|
||||
Notes for some targets:
|
||||
|
||||
- For Windows DLL versions, please see win32/DLL_FAQ.txt
|
||||
|
||||
- For 64-bit Irix, deflate.c must be compiled without any optimization. With
|
||||
-O, one libpng test fails. The test works in 32 bit mode (with the -n32
|
||||
compiler flag). The compiler bug has been reported to SGI.
|
||||
|
||||
- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
|
||||
when compiled with cc.
|
||||
|
||||
- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
|
||||
necessary to get gzprintf working correctly. This is done by configure.
|
||||
|
||||
- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
|
||||
other compilers. Use "make test" to check your compiler.
|
||||
|
||||
- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.
|
||||
|
||||
- For PalmOs, see http://palmzlib.sourceforge.net/
|
||||
|
||||
- When building a shared, i.e. dynamic library on Mac OS X, the library must be
|
||||
installed before testing (do "make install" before "make test"), since the
|
||||
library location is specified in the library.
|
||||
|
||||
|
||||
Acknowledgments:
|

The deflate format used by zlib was defined by Phil Katz. The deflate
|
||||
and zlib specifications were written by L. Peter Deutsch. Thanks to all the
|
||||
people who reported problems and suggested various improvements in zlib;
|

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.

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.

|
||||
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

||||
decoding tables.

Create and fill in decoding tables. In this loop, the table being
|
||||
filled is at next and has curr index bits. The code being used is huff
|
||||
with length len. That code is converted to an index by dropping drop
|
||||
bits off of the bottom. For codes where len is less than drop + curr,
|
||||
those top drop + curr - len bits are incremented through all values to
|
||||
fill the table with replicated entries.
|
||||
|
||||
root is the number of index bits for the root table. When len exceeds
|
||||
root, sub-tables are created pointed to by the root entry with an index
|
||||
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
|
||||
code lengths to determine what size sub-table is needed. The length
|
||||
counts are used for this, and so count[] is decremented as codes are
|
||||
entered in the tables.
|
||||
|
||||
used keeps track of how many table entries have been allocated from the
|
||||
provided *table space. It is checked when a LENS table is being made
|
||||
against the space in *table, ENOUGH, minus the maximum space needed by
|
||||
the worst case distance code, MAXD. This should never happen, but the
|
||||
sufficiency of ENOUGH has not been proven exhaustively, hence the check.
|
||||
This assumes that when type == LENS, bits == 9.
|
||||
|
||||
sym increments through all symbols, and the loop terminates when
|
||||
all codes of length max, i.e. all codes, have been processed. This
|
||||
routine permits incomplete codes, so another loop after this one fills
|
||||
in the rest of the decoding tables with invalid code markers.

.TH ZLIB 3 "2 October 2006"
|
||||
.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
|
||||
.IR gzip (1)
|
||||
(.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
|
||||
in the files
|
||||
.I example.c
|
||||
and

.IR minigzip.c .

.LP
|

Changes to this version are documented in the file

that accompanies the source,
