SYNOPSIS

 ($bz, $status) = bzdeflateInit( [PARAMS] ) ;
 ($out, $status) = $bz->bzdeflate($buffer) ;

 ($bz, $status) = bzinflateInit( [PARAMS] ) ;
 ($out, $status) = $bz->bzinflate($buffer) ;

 ($out, $status) = $bz->bzflush() ;
 ($out, $status) = $bz->bzclose() ;

 $dest = memBzip($source);
 alias compress
 $dest = memBunzip($source);
 alias decompress

 $bz = Compress::Bzip2->new( [PARAMS] );

 $bz = bzopen($filename or filehandle, $mode);
 alternate, with $bz created by new():
 $bz->bzopen($filename or filehandle, $mode);

 $bytesread = $bz->bzread($buffer [,$size]) ;
 $bytesread = $bz->bzreadline($line);
 $byteswritten = $bz->bzwrite($buffer [,$limit]);
 $errstring = $bz->bzerror();
 $status = $bz->bzeof();
 $status = $bz->bzflush();
 $status = $bz->bzclose() ;

 $status = $bz->bzsetparams( $param => $setting );

The Compress::Bzip2 module provides a Perl interface to the Bzip2 compression library (see "AUTHOR" for details about where to get Bzip2). A relevant subset of the functionality provided by Bzip2 is available in Compress::Bzip2.

All string parameters can either be a scalar or a scalar reference.

The module can be split into two general areas of functionality, namely in-memory compression/decompression and read/write access to bzip2 files. Each of these areas will be discussed separately below.
