The exceptions are listed below AutoClose => 0|1 The optional parameters for the one-shot function xz are (for the most part) identical to those used with the OO interface defined in the "Constructor Options" section.
#ERROR XZ COMPRESSION NOT AVAILABLE SERIES#
When $input_filename_or_reference maps to multiple files/buffers and $output_filename_or_reference is a single file/buffer the input files/buffers will be stored in $output_filename_or_reference as a concatenated series of compressed data streams. If the $output_filename_or_reference parameter is any other type, undef will be returned. When $output_filename_or_reference is an fileglob string, $input_filename_or_reference must also be a fileglob string. The output is the list of files that match the fileglob. If $output_filename_or_reference is a string that is delimited by the characters "" xz will assume that it is an output fileglob string. If $output_filename_or_reference is an array reference, the compressed data will be pushed onto the array. If $output_filename_or_reference is a scalar reference, the compressed data will be stored in $$output_filename_or_reference. The string '-' can be used as an alias for standard output. If the $output_filename_or_reference parameter is a filehandle, the compressed data will be written to it. This file will be opened for writing and the compressed data will be written to it. If the $output_filename_or_reference parameter is a simple scalar, it is assumed to be a filename. This parameter can take one of these forms.
The parameter $output_filename_or_reference is used to control the destination of the compressed data. The $output_filename_or_reference parameter If the $input_filename_or_reference parameter is any other type, undef will be returned. The input is the list of files that match the fileglob. If $input_filename_or_reference is a string that is delimited by the characters "" xz will assume that it is an input fileglob string. The complete array will be walked to ensure that it only contains valid filenames before any data is compressed. The input data will be read from each file in turn.
If $input_filename_or_reference is an array reference, each element in the array must be a filename. If $input_filename_or_reference is a scalar reference, the input data will be read from $$input_filename_or_reference. The string '-' can be used as an alias for standard input. If the $input_filename_or_reference parameter is a filehandle, the input data will be read from it. This file will be opened for reading and the input data will be read from it.
If the $input_filename_or_reference parameter is a simple scalar, it is assumed to be a filename. It can take one of the following forms: A filename The parameter, $input_filename_or_reference, is used to define the source of the uncompressed data. Xz expects at least two parameters, $input_filename_or_reference and $output_filename_or_reference and zero or more optional parameters (see "Optional Parameters") The $input_filename_or_reference parameter xz $input_filename_or_reference => $output_filename_or_reference The functional interface needs Perl5.005 or better.
Xz $input_filename_or_reference => $output_filename_or_reference For finer control over the compression process, see the "OO Interface" section. Functional InterfaceĪ top-level function, xz, is provided to carry out "one-shot" compression between buffers and/or files. This module provides a Perl interface that allows writing xz compressed data to files or buffer.įor reading xz files/buffers, see the companion module IO::Uncompress::UnXz. IO::Compress::Xz - Write xz files/buffers SYNOPSIS use IO::Compress::Xz qw(xz $XzError)
