The +output is the list of files that match the fileglob. + +When C<$output> is an fileglob string, C<$input> must also be a fileglob +string. Anything else is an error. + +=back + +If the C<$output> parameter is any other type, C<undef> will be returned. + +=head2 Notes + +When C<$input> maps to multiple files/buffers and C<$output> is a single +file/buffer the input files/buffers will be stored +in C<$output> as a concatenated series of compressed data streams. + +=head2 Optional Parameters + +Unless specified below, the optional parameters for C<bzip2>, +C<OPTS>, are the same as those used with the OO interface defined in the +L</"Constructor Options"> section below. + +=over 5 + +=item C<< AutoClose => 0|1 >> + +This option applies to any input or output data streams to +C<bzip2> that are filehandles. + +If C<AutoClose> is specified, and the value is true, it will result in all +input and/or output filehandles being closed once C<bzip2> has +completed. + +This parameter defaults to 0. + +=item C<< BinModeIn => 0|1 >> + +When reading from a file or filehandle, set C<binmode> before reading. + +Defaults to 0. + +=item C<< Append => 0|1 >> + +TODO + +=back + +=head2 Examples + +To read the contents of the file C<file1.txt> and write the compressed +data to the file C<file1.txt.bz2>. + + use strict ; + use warnings ; + use IO::Compress::Bzip2 qw(bzip2 $Bzip2Error) ; + + my $input = "file1.txt"; + bzip2 $input => "$input.bz2" + or die "bzip2 failed: $Bzip2Error\n"; + +To read from an existing Perl filehandle, C<$input>, and write the +compressed data to a buffer, C<$buffer>. + + use strict ; + use warnings ; + use IO::Compress::Bzip2 qw(bzip2 $Bzip2Error) ; + use IO::File ; + + my $input = new IO::File "<file1.txt" + or die "Cannot open 'file1.txt': $!\n" ; + my $buffer ; + bzip2 $input => \$buffer + or die "bzip2 failed: $Bzip2Error\n"; + +To compress all files in the directory "/my/home" that match "*.txt" +and store the compressed data in the same directory + + use strict ; + use warnings ; + use IO::Compress::Bzip2 qw(bzip2 $Bzip2Error) ; + + bzip2 '</my/home/*.txt>' => '<*.bz2>' + or die "bzip2 failed: $Bzip2Error\n"; + +and if you want to compress each file one at a time, this will do the trick + + use strict ; + use warnings ; + use IO::Compress::Bzip2 qw(bzip2 $Bzip2Error) ; + + for my $input ( glob "/my/home/*.txt" ) + { + my $output = "$input.bz2" ; + bzip2 $input => $output + or die "Error compressing '$input': $Bzip2Error\n"; + } + +=head1 OO Interface + +=head2 Constructor + +The format of the constructor for C<IO::Compress::Bzip2> is shown below + + my $z = new IO::Compress::Bzip2 $output [,OPTS] + or die "IO::Compress::Bzip2 failed: $Bzip2Error\n"; + +It returns an C<IO::Compress::Bzip2> object on success and undef on failure. +The variable C<$Bzip2Error> will contain an error message on failure. + +If you are running Perl 5.005 or better the object, C<$z>, returned from +IO::Compress::Bzip2 can be used exactly like an L<IO::File|IO::File> filehandle. +This means that all normal output file operations can be carried out +with C<$z>. +For example, to write to a compressed file/buffer you can use either of +these forms + + $z->print("hello world\n"); + print $z "hello world\n"; + +The mandatory parameter C<$output> is used to control the destination +of the compressed data.
