What does the gunzip function do in Perl?

This module provides a Perl interface that allows the reading of files/buffers that conform to RFC 1952. For writing RFC 1952 files/buffers, see the companion module IO::Compress::Gzip. A top-level function, gunzip, is provided to carry out “one-shot” uncompression between buffers and/or files.

What does$ gziperror mean in Perl 5.005?

The variable $GzipError will contain an error message on failure. If you are running Perl 5.005 or better the object, $z, returned from IO::Compress::Gzip can be used exactly like an IO::File filehandle. This means that all normal output file operations can be carried out with $z.

How does IO : Compress gzip work in Perl?

It returns an IO::Compress::Gzip object on success and undef on failure. The variable $GzipError will contain an error message on failure. If you are running Perl 5.005 or better the object, $z, returned from IO::Compress::Gzip can be used exactly like an IO::File filehandle.

What is the function of gunzip in Io?

A top-level function, gunzip, is provided to carry out “one-shot” uncompression between buffers and/or files. For finer control over the uncompression process, see the “OO Interface” section. The functional interface needs Perl5.005 or better.
