IO - load various IO modules
use IO qw(Handle File); # loads IO modules, here IO::Handle, IO::File
use IO; # DEPRECATED
"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; # 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 expli-
citly import the IO modules you want.
