1LZ4 - Library Files 2================================ 3 4The __lib__ directory contains several files, but you don't necessarily need them all. 5 6To integrate fast LZ4 compression/decompression into your program, you basically just need "**lz4.c**" and "**lz4.h**". 7 8For more compression at the cost of compression speed (while preserving decompression speed), use **lz4hc** on top of regular lz4. `lz4hc` only provides compression functions. It also needs `lz4` to compile properly. 9 10If you want to produce files or data streams compatible with `lz4` command line utility, use **lz4frame**. This library encapsulates lz4-compressed blocks into the [official interoperable frame format]. In order to work properly, lz4frame needs lz4 and lz4hc, and also **xxhash**, which provides error detection algorithm. 11(_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.) 12 13A more complex "lz4frame_static.h" is also provided, although its usage is not recommended. It contains definitions which are not guaranteed to remain stable within future versions. Use for static linking ***only***. 14 15The other files are not source code. There are : 16 17 - LICENSE : contains the BSD license text 18 - Makefile : script to compile or install lz4 library (static or dynamic) 19 - liblz4.pc.in : for pkg-config (make install) 20 21[official interoperable frame format]: ../lz4_Frame_format.md 22
