Description

libbz2(3)                  Library Functions Manual                  libbz2(3)



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 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.
