Name

libbz2 - library for block-sorting data compression

Synopsis

cc [ flag ...] file...” -lbz2 [ library ... ]

#include <stdio.h>
#include <bzlib.h>

Description

Interfaces in this library provide the ability to compress (and decompress) files using the Burrows-Wheeler blocksorting text compression algorithm, and Huffman coding. It is provided along with the bzip2(1) utility. See bzip2(1) for more information.

The source distribution of bzip2 contains a description of how to use this library in HTML form.

For additional information on shared object interfaces, see intro(3) .

The ideas embodied in bzip2 are due to (at least) the fol- lowing people: Michael Burrows and David Wheeler (for the block sorting transformation), David Wheeler (again, for the Huffman coder), Peter Fenwick (for the structured cod- ing model in the original bzip, and many refinements), and Alistair Moffat, Radford Neal and Ian Witten (for the arithmetic coder in the original bzip). I am much indebted for their help, support and advice. See the man- ual in the source distribution for pointers to sources of documentation. Christian von Roques encouraged me to look for faster sorting algorithms, so as to speed up compres- sion. Bela Lubkin encouraged me to improve the worst-case compression performance. Many people sent patches, helped with portability problems, lent machines, gave advice and were generally helpful.
