NAME
IO - load various IO modules
SYNOPSIS
use IO qw(Handle File); # loads IO modules, here IO::Handle, IO::File
use IO; # DEPRECATED
DESCRIPTION
"IO" provides a simple mechanism to load several of the IO modules in
one go. 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: <https://metacpan.org/search?q=IO%3A%3A>.
For more information on any of these modules, please see its respective
documentation.
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.
