libbz2(3)libbz2(3)NAMElibbz2 - 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 decom‐
press) 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 peo‐
ple: Michael Burrows and David Wheeler (for the block sorting trans‐
formation), 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 gener‐
ally helpful.
