IO - load various IO modules
use IO qw(Handle File);
use IO;
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 by searching for "^IO::" on http://search.cpan.org.
For more information on any of these modules, please see its respective
documentation.
use IO;
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.
