This directory contains a .Net wrapper class library for the ZLib1.dll

The wrapper includes support for inflating/deflating memory buffers,

.Net streaming wrappers for the gz streams part of zlib, and wrappers
|

for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.

Unit tests:
|
||||
-----------
|
||||
The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
|
||||
To include unit tests in the build, define nunit before building.
|
||||
|
||||
|
||||
Build instructions:
|
||||
-------------------
|
||||
|
||||
1. Using Visual Studio.Net 2003:
|
||||
Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
|
||||
will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
|
||||
you are building the release or debug version of the library. Check
|
||||
DotZLib/UnitTests.cs for instructions on how to include unit tests in the
|
||||
build.
|
||||
|
||||
2. Using NAnt:
|
||||
Open a command prompt with access to the build environment and run nant
|
||||
in the same directory as the DotZLib.build file.
|
||||
You can define 2 properties on the nant command-line to control the build:
|
||||
debug={true|false} to toggle between release/debug builds (default=true).
|
||||
nunit={true|false} to include or esclude unit tests (default=true).
|
||||
Also the target clean will remove binaries.
|
||||
Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
|
||||
or ./DotZLib/bin/debug, depending on whether you are building the release
|
||||
or debug version of the library.
|
||||
|
||||
Examples:
|
||||
nant -D:debug=false -D:nunit=false
|
||||
will build a release mode version of the library without unit tests.
|
||||
nant
|
||||
will build a debug version of the library with unit tests
|
||||
nant clean
|
||||
will remove all previously built files.

============

|
||||
- The project must build zlib using exclusively the source files from
|
||||
the official zlib distribution.
|
||||
- The project must build zlib using the source files from the official
|
||||
zlib source distribution, exclusively.
|
||||
|
||||
- If there are "official" makefiles in the zlib distribution, the builds
|
||||
given by the makefiles must be compatible with the builds given by the
|
||||
project. These builds are called "official" builds.
|
||||
- If the project produces redistributable builds (e.g. shared objects
|
||||
or DLL files), these builds must be compatible to those produced by
|
||||
makefiles, if such makefiles exist in the zlib distribution.
|
||||
In particular, if the project produces a DLL build for the Win32
|
||||
platform, this build must comply to the officially-ammended Win32 DLL
|
||||
Application Binary Interface (ABI), described in win32/DLL_FAQ.txt.
|
||||
|
||||
- It is possible to add non-official pieces of code to the project,
|
||||
if the resulting build remains compatible with an official build.
|
||||
For example, it is possible to add an "ASM build" target besides
|
||||
the regular target, by including ASM source files from the contrib
|
||||
directory.
|
||||
- The project may provide additional build targets, which depend on
|
||||
3rd-party (unofficially-supported) software, present in the contrib
|
||||
directory. For example, it is possible to provide an "ASM build",
|
||||
besides the officially-supported build, and have ASM source files
|
||||
among its dependencies.

||||
|
||||
- If there are significant differences between the project files created
|
||||
by different versions of an IDE (e.g. Visual C++ 6.0 vs. 7.0), the name

* Linking ZLIB1.DLL to MSVCR70.DLL, supplied with the

a good option. Although it is available for free download

and distribution, its presence is scarce on today's Win32
|
||||
installations. If it will ever become more popular than
|

MSVCRT.DLL and will be pre-installed on the future Win32
|

systems, we will probably think again about it.

* Linking ZLIB1.DLL to MSVCR70.DLL or MSVCR71.DLL, supplied
|
||||
with the Microsoft .NET platform, and Visual C++ 7.0/7.1,
|

raises problems related to the status of ZLIB1.DLL as a
|
||||
system component. According to the Microsoft Knowledge Base
|
||||
article KB326922 "INFO: Redistribution of the Shared C
|
||||
Runtime Component in Visual C++ .NET", MSVCR70.DLL and
|
||||
MSVCR71.DLL are not supposed to function as system DLLs,
|
||||
because they may clash with MSVCRT.DLL. Instead, the
|
||||
application's installer is supposed to put these DLLs
|
||||
(if needed) in the application's private directory.
|
||||
If ZLIB1.DLL depends on a non-system runtime, it cannot
|
||||
function as a redistributable system component.
|
||||
|
||||
* Linking ZLIB1.DLL to NTDLL.DLL is not possible.
|
||||
NTDLL.DLL exports only a part of the C library, and only on
|
||||
Windows NT systems.
|
||||
* Linking ZLIB1.DLL to non-Microsoft runtimes, such as
|
||||
Borland's, or Cygwin's, raises problems related to the
|
||||
reliable presence of these runtimes on Win32 systems.
|
||||
It's easier to let the DLL build of zlib up to the people

who distribute these runtimes, and who may proceed as

explained in the answer to Question 14.

|

how can I build/use ZLIB1.DLL in Microsoft Visual C++ 7.0
|
||||
(Visual Studio .NET) or newer?
|
||||
|
||||
- Due to the problems explained in the Microsoft Knowledge Base
|
||||
article KB326922 (see the previous answer), the C runtime that
|
||||
comes with the VC7 environment is no longer considered a
|
||||
system component. That is, it should not be assumed that this
|
||||
runtime exists, or may be installed in a system directory.
|
||||
Since ZLIB1.DLL is supposed to be a system component, it may
|
||||
not depend on a non-system component.
|
||||
|
||||
In order to link ZLIB1.DLL and your application to MSVCRT.DLL
|
||||
in VC7, you need the library of Visual C++ 6.0 or older. If
|
||||
you don't have this library at hand, it's probably best not to
|
||||
use ZLIB1.DLL.
|
||||
|
||||
We are hoping that, in the future, Microsoft will provide a
|
||||
way to build applications linked to a proper system runtime,
|
||||
from the Visual C++ environment. Until then, you have a
|
||||
couple of alternatives, such as linking zlib in statically.

If your application requires dynamic linking, you may proceed

The compressed data format used by the in-memory functions is the zlib

around a deflate stream, which is itself documented in RFC 1951.
|
||||
|
||||
The library also supports reading and writing files in gzip (.gz) format
|
||||
with an interface similar to that of stdio using the functions that start
|
||||
with "gz". The gzip format is different from the zlib format. gzip is a
|
||||
gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
|
||||
|
||||
This library can optionally read and write gzip streams in memory as well.
|
||||
|
||||
The zlib format was designed to be compact and fast for use in memory
|
||||
and on communications channels. The gzip format was designed for single-
|
||||
file compression on file systems, has a larger header than zlib to maintain
|
||||
directory information, and uses a different, slower check method than zlib.
|
||||
|
||||
This library does not provide any functions to write gzip files in memory.
|
||||
However such functions could be easily written using zlib's deflate function,
|
||||
the documentation in the gzip RFC, and the examples in gzio.c.
|
||||
|
||||
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.
