The lzip file format is designed for long-term data archiving. It is clean, provides very safe 4 factor integrity checking, and is backed by the recovery capabilities of lziprecover.
The functions and variables forming the interface of the compression library are declared in the file lzlib.h. Usage examples of the library are given in the files main.c and bbexample.c from the source distribution.
Compression/decompression is done by repeatedly calling a couple of read/write functions until all the data has been processed by the library. This interface is safer and less error prone than the traditional zlib interface.
Lzlib will correctly decompress a data stream which is the concatenation of two or more compressed data streams. The result is the concatenation of the corresponding decompressed data streams. Integrity testing of concatenated compressed data streams is also supported.
All the library functions are thread safe. 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.
Lzlib implements a simplified version of the LZMA (Lempel-Ziv-Markov chain-Algorithm) algorithm. The original LZMA algorithm was designed by Igor Pavlov. For a description of the LZMA algorithm, see the lzip manual.
