NAME

Tie::Handle - base class definitions for tied handles

SYNOPSIS

package NewHandle;
require Tie::Handle;
@ISA = qw(Tie::Handle);
sub READ { ... }		# Provide a needed method
sub TIEHANDLE { ... }	# Overrides inherited method
package main;
tie *FH, 'NewHandle';

DESCRIPTION

This module provides some skeletal methods for handle-tying classes. See perltie for a list of the functions required in tying a handle to a package. The basic Tie::Handle package provides a new method, as well as methods TIEHANDLE, PRINT, PRINTF and GETC.

For developers wishing to write their own tied-handle classes, the methods are summarized below. The perltie section not only documents these, but has sample code as well:

MORE INFORMATION

The perltie section contains an example of tying handles.

COMPATIBILITY

This version of Tie::Handle is neither related to nor compatible with the Tie::Handle (3.0) module available on CPAN. It was due to an accident that two modules with the same name appeared. The namespace clash has been cleared in favor of this module that comes with the perl core in September 2000 and accordingly the version number has been bumped up to 4.0.
