miniLZO -- mini subset of the LZO real-time data compression library
|
||||
============================================================================
|
||||
|
||||
Author : Markus Franz Xaver Johannes Oberhumer
|
||||
<markus@oberhumer.com>
|
||||
http://www.oberhumer.com/opensource/lzo/
|
||||
Version : 2.03
|
||||
Date : 30 Apr 2008
|
||||
|
||||
I've created miniLZO for projects where it is inconvenient to
|
||||
include (or require) the full LZO source code just because you
|
||||
want to add a little bit of data compression to your application.
|
||||
|
||||
miniLZO implements the LZO1X-1 compressor and both the standard and
|
||||
safe LZO1X decompressor. Apart from fast compression it also useful
|
||||
for situations where you want to use pre-compressed data files (which
|
||||
must have been compressed with LZO1X-999).
|
||||
|
||||
miniLZO consists of one C source file and three header files:
|
||||
minilzo.c
|
||||
minilzo.h, lzoconf.h, lzodefs.h
|
||||
|
||||
To use miniLZO just copy these files into your source directory, add
|
||||
minilzo.c to your Makefile and #include minilzo.h from your program.
|
||||
Note: you also must distribute this file (`README.LZO') with your project.
|
||||
|
||||
minilzo.o compiles to about 6 kB (using gcc or Visual C on a i386), and
|
||||
the sources are about 30 kB when packed with zip - so there's no more
|
||||
excuse that your application doesn't support data compression :-)
|
||||
|
||||
For more information, documentation, example programs and other support
|
||||
files (like Makefiles and build scripts) please download the full LZO
|
||||
package from
|
||||
http://www.oberhumer.com/opensource/lzo/
|
||||
|
||||
Have fun,
|
||||
Markus
|
||||
|
||||
|
||||
P.S. minilzo.c is generated automatically from the LZO sources and
|
||||
therefore functionality is completely identical
|
||||
|
||||
|
||||
Appendix A: building miniLZO
|
||||
----------------------------
|
||||
miniLZO is written such a way that it should compile and run
|
||||
out-of-the-box on most machines.
|
||||
|
||||
If you are running on a very unusual architecture and lzo_init() fails then
|
||||
you should first recompile with `-DLZO_DEBUG' to see what causes the failure.
|
||||
The most probable case is something like `sizeof(char *) != sizeof(long)'.
|
||||
After identifying the problem you can compile by adding some defines
|
||||
like `-DSIZEOF_CHAR_P=8' to your Makefile.
|
||||
|
||||
The best solution is (of course) using Autoconf - if your project uses
|
||||
Autoconf anyway just add `-DMINILZO_HAVE_CONFIG_H' to your compiler
|
||||
flags when compiling minilzo.c. See the LZO distribution for an example
|
||||
how to set up configure.in.
|
||||
|
||||
|
||||
Appendix B: list of public functions available in miniLZO

||||
