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'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<https://metacpan.org/search?q=IO%3A%3A>. 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
