The IO modules belonging to the core are: IO::Handle IO::Seekable IO::File IO::Pipe IO::Socket IO::Dir IO::Select IO::Poll Some other IO modules don&#39;t belong to the perl core but can be loaded as well if they have been installed from CPAN. You can discover which ones exist with this query: L&lt;https://metacpan.org/search?q=IO%3A%3A&gt;. For more information on any of these modules, please see its respective documentation. =head1 DEPRECATED use IO; # loads all the modules listed below The loaded modules are IO::Handle, IO::Seekable, IO::File, IO::Pipe, IO::Socket, IO::Dir. You should instead explicitly import the IO modules you want. =cut </code></pre> </main> <div class="content-pagination"> </div> </div> <footer class="footer"> <div class="footer-container"> <div
