LZ4 - Library Files
|
||||
================================
|
||||
|
||||
The directory contains many files, but depending on project's objectives,
|
||||
not all of them are necessary.
|
||||
|
||||
#### Minimal LZ4 build
|
||||
|
||||
The minimum required is **`lz4.c`** and **`lz4.h`**,
|
||||
which will provide the fast compression and decompression algorithm.
|
||||
|
||||
|
||||
#### The High Compression variant of LZ4
|
||||
|
||||
For more compression at the cost of compression speed,
|
||||
the High Compression variant **lz4hc** is available.
|
||||
It's necessary to add **`lz4hc.c`** and **`lz4hc.h`**.
|
||||
The variant still depends on regular `lz4` source files.
|
||||
In particular, the decompression is still provided by `lz4.c`.
|
||||
|
||||
|
||||
#### Compatibility issues
|
||||
|
||||
In order to produce files or streams compatible with `lz4` command line utility,
|
||||
it's necessary to encode lz4-compressed blocks using the [official interoperable frame format].
|
||||
This format is generated and decoded automatically by the **lz4frame** library.
|
||||
In order to work properly, lz4frame needs lz4 and lz4hc, and also **xxhash**,
|
||||
which provides error detection.
|
||||
(_Advanced stuff_ : It's possible to hide xxhash symbols into a local namespace.
|
||||
This is what `liblz4` does, to avoid symbol duplication
|
||||
in case a user program would link to several libraries containing xxhash symbols.)
|
||||
|
||||
|
||||
#### Advanced API
|
||||
|
||||
A more complex `lz4frame_static.h` is also provided.
|
||||
It contains definitions which are not guaranteed to remain stable within future versions.
|
||||
It must be used with static linking ***only***.
|
||||
|
||||
|
||||
#### Using MinGW+MSYS to create DLL
|
||||
|
||||
DLL can be created using MinGW+MSYS with the `make liblz4` command.
|
||||
This command creates `dll\liblz4.dll` and the import library `dll\liblz4.lib`.
|
||||
The import library is only required with Visual C++.
|
||||
The header files `lz4.h`, `lz4hc.h`, `lz4frame.h` and the dynamic library
|
||||
`dll\liblz4.dll` are required to compile a project using gcc/MinGW.
|
||||
The dynamic library has to be added to linking options.
|
||||
It means that if a project that uses LZ4 consists of a single `test-dll.c`
|
||||
file it should be linked with `dll\liblz4.dll`. For example:
|
||||
```
|
||||
gcc $(CFLAGS) -Iinclude/ test-dll.c -o test-dll dll\liblz4.dll
|
||||
```
|
||||
The compiled executable will require LZ4 DLL which is available at `dll\liblz4.dll`.
|
||||
|
||||
|
||||
#### Miscellaneous
|
||||
|
||||
Other files present in the directory are not source code. There are :
|
||||
|
||||
- LICENSE : contains the BSD license text
|
||||
- Makefile : script to compile or install lz4 library (static or dynamic)

Introduction
|
||||
|
||||
LZ4 is lossless compression algorithm, providing compression speed at 400 MB/s per core,
|
||||
scalable with multi-cores CPU. It features an extremely fast decoder, with speed in
|
||||
multiple GB/s per core, typically reaching RAM speed limits on multi-core systems.
|
||||
|
||||
The LZ4 compression library provides in-memory compression and decompression functions.
|
||||
Compression can be done in:
|
||||
- a single step (described as Simple Functions)
|
||||
- a single step, reusing a context (described in Advanced Functions)
|
||||
- unbounded multiple steps (described as Streaming compression)
|
||||
|
||||
lz4.h provides block compression functions. It gives full buffer control to user.
|
||||
Decompressing an lz4-compressed block also requires metadata (such as compressed size).
|
||||
Each application is free to encode such metadata in whichever way it wants.
|
||||
|
||||
An additional format, called LZ4 frame specification (doc/lz4_Frame_format.md),
|
||||
take care of encoding standard metadata alongside LZ4-compressed blocks.
|
||||
If your application requires interoperability, it's recommended to use it.
|
||||
A library is provided to take care of it, see lz4frame.h.
