.TH libbz2 3 "8 Oct 1999" .SH NAME libbz2 \- library for block-sorting data compression .SH SYNOPSIS .LP .B cc .RI "[ " "flag " \|.\|.\|. ] " "file \|.\|.\|." .B \-lbz2 .RI "[ " "library" " \|.\|.\|. ]" .sp 1n .nf .ft 3 #include #include .ft .fi .SH 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 .BR bzip2(1) utility. See .BR bzip2(1) for more information. .LP The source distribution of bzip2 contains a description of how to use this library in HTML form. .LP For additional information on shared object interfaces, see .BR intro(3). .SH INTERFACES .nf BZ2_bzCompressInit BZ2_bzCompress BZ2_bzCompressEnd BZ2_bzDecompressInit BZ2_bzDecompress BZ2_bzDecompressEnd BZ2_bzReadOpen BZ2_bzReadClose BZ2_bzReadGetUnused BZ2_bzRead BZ2_bzWriteOpen BZ2_bzWrite BZ2_bzWriteClose BZ2_bzBuffToBuffCompress BZ2_bzBuffToBuffDecompress BZ2_bzlibVersion BZ2_bzopen BZ2_bzdopen BZ2_bzread BZ2_bzwrite BZ2_bzflush BZ2_bzclose .fi .SH FILES .PD 0 .TP 20 /usr/lib/libbz2.so.1 shared object .TP /usr/lib/64/libbz2.so.1 64-bit shared object .PD .SH "SEE ALSO" bzip2(1), intro(3) .SH AUTHOR Julian Seward, jseward@acm.org. http://sourceware.cygnus.com/bzip2 http://www.muraroa.demon.co.uk 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.
