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 explicitly import the IO modules you want.
