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 compressed data format used by the in-memory functions is the zlib
|
||||
format, which is a zlib wrapper documented in RFC 1950, wrapped around a
|

deflate stream, which is itself documented in RFC 1951.

the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped

around a deflate stream, which is itself documented in RFC 1951.
|
||||
|
||||
The library also supports reading and writing files in gzip (.gz) format
|
||||
with an interface similar to that of stdio using the functions that start
|
||||
with "gz". The gzip format is different from the zlib format. gzip is a
|
||||
gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
|
||||
|
||||
This library can optionally read and write gzip 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.
